Mother of god, was listening to the US govt hearing of zuckerberg about the recent scandals. The amount of very fucking simple obvious questions he 'could not' answer normally...

Govt person: Would you be willing to change Facebook's business model if this was required for the security and privacy of Facebook users' accounts?

Zuck: I don't understand your question.

Sorry, WHAT?! You don't need particular rocket science to understand what's being asked here. A combination of common sense and knowing the English language and English grammar in combination with maybe having finished some form of education should be enough to understand this ridiculously easy question.

Do you need it written on a golden plate with fucking blue letters in Facebook's font with the S letters as dollar signs while drinking 10 gallons of 'fuck every persons privacy'?!

Or maybe shoving it up your ass in the form of heated/glowing metal letters of 10+ inches in height? We could arrange that as well.

School principal : P / Me : M / Interviewer over Skype : S

P. I recently heard you run a software club in our school.
M. Yes. (started from March)
P. Well, one software community seems that he found you somewhere, and asked me if we can do a quick interview.
M. Sure. What is it?
P. So he will connect to skype.
M. Let's start then...

*A few moments later...*
M. Wwwwhhhhaaaaattttttt?
P. Calm down! What's the problem?
M. How can I have more than 5 years of android development?
S. Ok. Recorded. Next question.
M. (uhhh)
*A few moments later...*
M. What? Why in the heck do I use subversion?........
Yes... Ah... Ummm....
No! Why should i make a gui client for subversion?
*A few moments later...*
S. Do you have hacking experience?
M. Of what? I know hacking is illegal here..
S. Like... Anything!
M. Do YOU have an experience?
S. Yup.
M. What?
S. Google.
M. How?
S. (silence) Ok. Let's move on.
M. (wtf is this guy)
*A few moments later...*
S. Okay. We were about to hire you but you didnt met our job requirements.
M. ......What? What was the job?
S. Web developer Intern
M. I got no questions regarding "web".
S. I know devs should be great at all things.
M. Shut the hell up. What company are you?
S. (says something)
M. (Searches in google) Doesnt come in search results.
S. Where did you searched it? (trembling voice)
M. (Searches in naver, search engine of korea) Nothing. Are you sure you are a company?
S. (ends call)

Hate these fake interviews. And i have no idea how they found my school
I never wrote my school anywhere.

It seems like every other day I run into some post/tweet/article about people whining about having the imposter syndrome. It seems like no other profession (except maybe acting) is filled with people like this.

Well lemme answer that question for you lot.

YES YOU ARE A BLOODY IMPOSTER.

There. I said it. BUT.

Know that you're already a step up from those clowns that talk a lot but say nothing of substance.

You're better than the rockstar dev that "understands" the entire codebase because s/he is the freaking moron that created that convoluted nonsensical pile of shit in the first place.

You're better than that person who thinks knowing nothing is fine. It's just a job and a pay cheque.

The main question is, what the flying fuck are you going to do about being an imposter? Whine about it on twtr/fb/medium? HOW ABOUT YOU GO LEARN SOMETHING BEYOND FRAMEWORKS OR MAKING DUMB CRUD WEBSITES WITH COLOR CHANGING BUTTONS.

Computers are hard. Did you expect to spend 1 year studying random things and waltz into the field as a fucking expert? FUCK YOU. How about you let a "doctor" who taught himself medicine for 1 year do your open heart surgery?

Learn how a godamn computer actually works. Do you expect your doctors and surgeons to be ignorant of how the body works? If you aspire to be a professional WHY THE FUCK DO YOU STAY AT THE SURFACE.

Go learn about Compilers, complete projects with low level languages like C / Rust (protip: stay away from C++, Java doesn't count), read up on CPU architecture, to name a few topics.

Then, after learning how your computers work, you can start learning functional programming and appreciate the tradeoffs it makes. Or go learn AI/ML/DS. But preferably not before.

Basically, it's fine if you were never formally taught. Get yourself schooled, quit bitching, and be patient. It's ok to be stupid, but it's not ok to stay stupid forever.

Once upon a time in Devland, there were two best friends @Alice and @Michelle and they worked together at The DevCo company as developers.
After a tough day handling an @-ANGRY-CLIENT-, they thought that they had to go and @RantSomewhere and so they went to a café. At the café, they ranted about some stupid clients, and @theItalianGuy at the third floor of their office building who never picked up calls, and @thatJavaGuy from the second floor who, they thought, was @notarealDev, and the usual stuff about their work. Somewhere in between, @Alice thought it would be @funvengeance to @hack @theNSA; “@karma is coming to get them”, said @Michelle.
To do this, they knew they’d have to take help from none other than @Gandalf who lived in a nearby @cave. So, the next day, taking a leave from work, @Alice and @Michelle embarked on journey to meet @Gandalf. After about an hour’s drive, they reached @Gandalf’s @cave. @Michelle went ahead to knock on @Gandalf’s rusty cave door. Being a lazy @necromancer, he magically opened his door 2 minutes later. “Who is't dares to disturb me in mine own catch but a wink?” shouted a voice from the back; “We’re two developers from DevCo and we need your help in our mission to @hack @theNSA”, shouted @Michelle. After a few seconds, he replied, ”Hmm… N'rmally I wouldst sendeth thee to mine own cousin @Hagrid, but in thy case, I sayeth thee shouldst visiteth the detective who is't goeth by the nameth @S-Holmes”. @Alice replied back, “Thank you, Sir @Gandalf, we’ll get help from this @S-Holmes, I’ve heard that he’s an @exceptionalGuy”; “Mine own pleasure, Farewell!” said @Gandalf, and the door closed shut.
So, @Alice and @Michelle went back to their car, and that time @Alice raised a question, “How are we gonna find this @S-Holmes? We don’t have a phone number or anything so we could contact this guy.”
“We should call @thatJavaGuy from work, I’ve heard he is a man of resources, he must know how to contact @S-Holmes”, said @Michelle.
And it was true, after a call with @thatJavaGuy, they were able to obtain @S-Holmes’s phone number.
“Howdy, this is @S-Holmes, what can I diddily ding dong do you for?”
“Hi, I’m @Alice, I’m from DevCo and I was hoping that I could get your help in our mission.”
“What kind of mission?”, asked @S-Holmes.
“We want to @hack @theNSA.”, replied @Alice.
“Okay… I think I might be able to hel-diddly-elp you! There’s an old and abandoned laberino noodly-near @stacked Street. It was made in @1989 and since then, it houses a magical computeroo that can hel-diddly-elp you in your mission. So, you just have to connect the computeroo to the Internet and you can diddily ding dong do your programmeroo thing and then you'll have access to the the noodly-nsa diddily ding dong database!”, answered @S-Holmes.
S-Holmes continued, “But I shall warn you, there's a riddly-rumorino that the laberino was abandoned because of an @electric-ghost that lurks there, but I bel-diddly-elieve it is just a computeroo program that was diddily ding dong designed to try to @stop hackers from accessing the top secret stuff!".
“Okay, thanks for your help! I bet we can handle whatever this @electric-ghost thing is, so… Goodbye!”, replied @Alice.
“Goodbye!”, said @S-Holmes and that ended their conversation.
Luckily, the @stacked Street was just a couple of miles away from them, so they reached the lab quickly.
As they got close to the lab they saw something that really surprised them…

To be continued in part two...
(Do you want a part two? :/)

My first ever story is a little special because it is kind of dev related at it has "cameos" by various devranters, as you might have noticed.
How many did you count?
More in Part Two.

Thank you for reading and please, any feedback is welcome. Did you like it?
I haven't really revised it once, it is straight out of the keyboard.
Should I drop the "@" ?
But then it would impossible to spot some of the devRanters .
Let me know.

PS
What should be the title?
1)Alice in DevLand?
2)Adventures of Alice and Friends: Hacking the NSA?
You decide..(or maybe I'll pick the second one :D)

Following a conversation with a fellow devRanter this came to my mind ago, happened a year or two ago I think.

Was searching for an online note taking app which also provided open source end to end encryption.

After searching for a while I found something that looked alright (do not remember the URL/site too badly). They used pretty good open source JS crypto libraries so it seemed very good!

Then I noticed that the site itself did NOT ran SSL (putting the https:// in front of the site name resulted in site not found or something similar).

Went to the Q/A section because that's really weird.

Saw the answer to that question:

"Since the notes are end to end encrypted client side anyways, we don't see the point in adding SSL. It's secure enough this way".

😵

I emailed them right away explaing that any party inbetween their server(s) and the browser could do anything with the request (includingt the cryptographic JS code) so they should start going onto SSL very very fast.

Too badly I never received a reply.

People, if you ever work with client side crypto, ALWAYS use SSL. Also with valid certs!

The NSA for example has this thing known as the 'Quantum Insert' attack which they can deploy worldwide which basically is an attack where they detect requests being made to servers and reply quickly with their own version of that code which is very probably backdoored.

This attack cannot be performed if you use SSL! (of course only if they don't have your private keys but lets assume that for now)
Luckily Fox-IT (formerly Dutch cyber security company) wrote a Snort (Intrustion Detection System) module for detecting this attack.

Anyways, Always use SSL if you do anything at all with crypto/sensitive data! Actually, always use it but at the very LEAST really do it when you process the mentioned above!

A Fellow Ranter said I should introduce myself, so here I go.

Me = {
Gender = "Male",
CodeOfChoise = {"lua", "PHP"},
Age = "28"
Location = "404"
}

No really here we go, I am Rex, I am dyslexic and forget code really badly but it does not stop me from trying to have fun with some ideas, I use mostly PHP these days but when I want to make a quick windows tool I use a app called AMS or AutoPlayMedia Studios what as a nice lua scripting language back end.

I been coding on and off for many years since I was about 15 and I been in love with computers since I was about 6 (don't tell my wife).

So far I like the site, its better then Twitter and Facebook as it's code related and fun to read and some stuff gets the cogs a turning.

I don't have any real foot print in the dev world, I get by but I not here to be loved, or to be big in any field, I am here because I enjoy my tech.

I leave this little introduce me with a question, what was your first or first memorial computer.

Mine was the Acorn A4000 Mixed with parts from the A3000 and A5000's :) she was a little bit of a mix match.

Story Time. Inspired by another rant.

Context: I'm In a coding camp years ago, it's the first day.

We're doing introductions (name, why you're here, etc). Always fun to do that....

The folks running the camp are excited to introduce a student who also at one point was a teacher for some sort of girl power coding organization. So this raises questions, why would someone who teaches be a student in this camp?? And even a bigger question is raised when this person introduces themselves for a long time, and as an aside puts down the girls she taught in this program they taught ... like who does that?

horribleLady does that ...

A few hours later horribleLady asks her 12th question of the day (we haven't even started talking about code). Before she asks her question actually says:

“I know, I’m going to be a problem.” -laugh-

🚨🚨🚨 ヽ ( ꒪д꒪ )ﾉ 🚨🚨🚨

Fast forward to group projects and she's this sort of emotional storm, tears, and a sort of angry shouting that isn't angry enough for some folks to say she's yelling at people ... but she is. Fortunately I'm not in the first group project with her, but because we're all working in the same room we all get to see the train-wreck unfold.

The moment she doesn't get something (all the time) everyone in her group has to STOP and figure out what they're going to do about it, then again STOP because she thinks someone is doing something different than what was planned. STOP STOP STOP STOP STOP.

In a way, everything had to go through her, she didn’t declare it that way, she didn't present herself as any sort of authority, she would just stop everyone the moment she thought anything was wrong, or she didn't understand it (all the time), and either inject herself or demand help from her team. Everyone around her had to be drawn into whatever problem she had. It was horrific to watch.

Private slack channels would light up like crazy with "OMG", "WTF", "I DON'T UNDERSTAND HER", "FUCK" and "SHE"S HOW OLD!?!?"

So finally it happens to me and guyWhoDoesPotConstantly (capable guy, nice dude, pretty sure he was high all the time).... we're teamed up to work with horribleLady. Thankfully for just one day. I accept this because I figure one day with her is enough penance to try to avoid any further contact later on.

My approach is straight stone face. I refuse to respond to her sulking, or sighing, or general emotional bait she throws out constantly. I saw other students unwittingly take her bait (they were trying to be helpful) only to have her crap all over them with her frustrations or whatever it is is going on.

Still we're teamed up with her her for the day so I'm going to be a good team member and I explain what guyWhoDoesPotConstantly and I are doing / trying.... and so forth. But she's just too upset that she's even assigned to work with us, and tells me I'm just not doing it right, and her explanations about how we're not doing it right makes less than 0 sense. I ask her to show me what she means but she won't type anything on her keyboard, she'd just talk about how she’s thinking conceptually in circles and sulk about it rather than listen. I don't respond to any of her shit and say "I'm going to try this." and guyWhoDoesPotConstantly and I just keep working.

She would later call the instructor over and complain to him for a while and say: "These guys just get it, they're not helping me, I want to be assigned to another group." She doesn't get her way so she just moves to another table in front of us.

After that day I figured it was a great time to ask .... to NEVER be assigned to anything with her because "If I told her what I thought it would just get a lot worse." I got my way ;)

Other students weren't so lucky. Tears, sulking, her special way of yelling at people that somehow never got her in trouble (she should have been kicked out of the program) just kept going on. She refused to even present one group project she deemed not good enough despite the fact that she contributed nothing functional to the project that the TA's didn't write for her...

Amidst the stories she would tell to students was one of how she sued her totally sexist/racist/evil former employer. She never said what came of it, but that combined with her inability to do things reminded me of a rant I read on here.

I sometimes fear being hired someplace and walking in my first day to find I'm assigned to work with .... horribleLady. In this scenario she managed to get hired and they're too afraid to fire her so they assign the new guy to work with horribleLady...

I've no idea what happened to her after the camp.

(I rewrote this rant a few times because it kept circling back to a larger story about the coding camp I wrote about a few years ago, so if this seemed sort of broken up and wonky, yeah it was / is / yeah)

My code review nightmare part 2

Team responsible for code 'quality' dictated in their 18+ page coding standard document that all the references in the 'using' block be sorted alphabetically. Easy enough in Visual Studio with the right-click -> 'Remove and Sort Usings', so I thought.

Called into a conference room with other devs and the area manager (because 'Toby' needed an audience) focusing on my lack of code quality and not adhering to the coding standard.

The numerous files in question were unit tests files

using Microsoft.VisualStudio.TestTools.UnitTesting;
using System.Collections.Generic;
using System.Linq;
<the rest of the usings>

T: "As you can see, none of these files' usings are in alphabetical order"
Me: "Um, I think they are. M comes before S"
T: "The standards clearly dictate system level references are to be sorted first."
Mgr: "Yes, why didn't you sort before checking this code in? T couldn't have made the standards any easier to follow. All you had to do is right-click and sort."
Me: "I did. M comes before S."
T: "No You Didn't! That is not a system reference!"
Me: "I disagree. MSTest references are considered a system level reference, but whatever, I'll move that one line if it upsets you that much."
Mgr: "OK smartass, that's enough disrespect. Just follow the fucking standard."
T: "And learn to sort. It's easy. You should have learned that in college"
<Mgr and T have a laugh>
Me: "Are all your unit tests up to standard? I mean, are the usings sorted correctly?"
T:"Um..well..of course they are!"
Me: "Lets take a look."

I had no idea, a sorted usings seems like a detail no one cares about that much and something people do when bored. I navigate to project I knew T was working on and found nearly all the file's usings weren't sorted. I pick on one..

using NUnit;
using Microsoft.Something.Other;
using System;
<the rest of the usings>

Me: "These aren't sorted..."
T: "Uh..um...hey...this file is sorted. N comes before M!"
Me: "Say that again. A little louder please."
Mgr: "NUnit is a system level nuget package. It's fine. We're not wasting time fixing some bug in how Visual Studio sorts"
Me: "Bug? What?..wait...and having me update 10 or so files isn't a waste of time?"
Mgr: "No! Coding standards are never a waste of time! We're done here. This meeting is to review your code and not T's. Fix your bugs and re-submit the code for review..today!"

Find a place where management is able to handle some criticism.

I personally think Agile/Scrum is holy, and I don't mean "yeah we kind of do our own version of it", no, fucking do it by the book. The PM shouldn't assign estimates. Developers shouldn't receive bugfix requests from anyone other than the scrum master. The CTO can't be your scrum master... etc.

If a company can't answer the question "What were the points of feedback during the last retrospective(s), and how are those points being picked up?" -- Don't work there.

Many other things are optional in my opinion. I could work at a company without QA, without fruit baskets, table tennis, without Friday drinks. I could even live without git & continuous integration, just emailing patches to a patch integrator. I don't care.

But maintaining a safe bubble of serenity and sanity for devs to do their work in, that is an absolute must.

Also, option to WFH as much as wanted. Offices are nice for social bonding, but they kill productivity for me.

How almost every S/O question looks

I'll use this topic to segue into a related (lonely) story befitting my mood these past weeks.

This is entire story going to sound egotistical, especially this next part, but it's really not. (At least I don't think so?)

As I'm almost entirely self-taught, having another dev giving me good advice would have been nice. I've only known / worked with a few people who were better devs than I, and rarely ever received good advice from them.

One of those better devs was my first computer science teacher. Looking back, he was pretty average, but he held us to high standards and gave good advice. The two that really stuck with me were: 1) "save every time you've done something you don't want to redo," and 2) "printf is your best debugging friend; add it everywhere there's something you want to watch." Probably the best and most helpful advice I've ever received 😊

I've seen other people here posting advice like "never hardcode" or "modularity keeps your code clean" -- I had to discover these pretty simple concepts entirely on my own. School (and later college) were filled with terrible teachers and worse students, and so were almost entirely useless for learning anything new.

The only decent dev I knew had brilliant ideas (genetic algorithms, sandboxing, ...) before they were widely used, but could rarely implement them well because he was generally an idiot. (Idiot sevant, I think? Definitely the idiot part.) I couldn't stand him. Completely bypassing a ridiculously long story, I helped him on a project to build his own OS from scratch; we made very impressive progress, even to this day. Custom bootloader, hardware interfacing, memory management, (semi) sandboxed processes, gui, example programs ...; we were in highschool. I'm still surprised and impressed with what we accomplished.

But besides him, almost every other dev I met was mediocre. Even outside of school, I went so many years without having another competent dev to work with. I went through various jobs helping other dev(s) on their projects (or rewriting them), learning new languages/frameworks almost every time: php, pascal, perl, zend, js, vb, rails, node, .... I learned new concepts occasionally (which was wonderful) but overall it was just tedious and never paid well because I was too young to be taken seriously (and female, further exacerbating it). On the bright side, it didn't dwindle my love for coding, and I usually spent my evenings playing with projects of my own.

The second dev (and one one of the best I've ever met) went by Novo. His approach to a game engine reminded me of General Relativity: Everything was modular, had a rich inheritance tree, and could receive user input at any point along said tree. A user could attach their view/control to any object. (Computer control methods could be attached in this way as well.) UI would obviously change depending on how the user could interact and the number of objects; admins could view/monitor any of these. Almost every object / class of object could talk to almost everything else. It was beautiful. I learned so much from his designs. (Honestly, I don't remember the code at all, and that saddens me.) There were other things, too, but that one amazed me the most.

I havent met anyone like him ever again.

Anyway, I don't know if I can really answer this week's question. I definitely received some good advice while initially learning, but past that it's all been through discovering things on my own.

It's been lonely. ☹

Published a new blog article last weekend (finally) and had the idea to make a privacy/security Q&A one this weekend.

I'd make an email address for it to which you can email (a) question(s).

What do you people think?

I keep wondering if there’s a case of someone stealing another’s rant. And what the other person would say to the thief.

“You stole my rant” or “That was suppose to be my rant” or something along that line.

😅

You have to integrate company A system with company B.
You look up B`s api documentation, write the necessary code, test it thoroughly. Done
__________________________________
A wild dev from B has appeared!!!
------------------------------------------------------

him > you cannot use this SDK to implement this solution. You must use a different one...

You > (coming back to him after scouring through the docs) . Ok which sdk is it then? I can't find it anywhere. Could you send it to me pls?
him > I don't kbow, my knowledge doesn't go that far. Send an email to the dev department.

After sending the email, and spending a couple of days trying to figure out which sdk was he referring to. His department answers that the sdk you should use, is the one you already used. The only one they have.

A couple of days lost, because certain smart-ass could not refrain himself from meddling in the project.

What would you do?

Note: Killing him is out of the question :)

The other day, I customer of ours asked me to try to improve the performance of an application of his in a particular method. The method in question taking more than 5 minutes.
I took a look at what it did in the profiler, and it shocked me. More than 100k selects to the database, to retrieve 116 records...
I took a look at the code... Scores of selects in nested loops inside other nested loops inside of... That seemed normal to them...
At the end after we improved it's performance it took 3 seconds...
What shocks me the most is that the customer is a developer himself, really knowledgeable and has an order of magnitude more experience than I do. Am I too anti "worthless database round-trips"? Is that normal? :S

University Final Viva for OOP with C++
(Yeah, that first line is a rant in itself for the likes of me and Mr. Torvalds)
Assistant Professor:
Tell me a few "functions" in C++ STL algorithm header
Me:
*starts off with the first one that came to my mind*
sort()
AP: Huh? a I'm asking the Algorithms in C++ STL
Me: Yes, this is one of them Ma'am.
She looked at me as if I told her that I'm dating her daughter. It became clear she doesn't know about it and she'll gladly deduct my marks for getting it wrong. So I explained how Sort() is a hybrid of quicksort, heap sort and insertion sort. (Read about it an hour ago while doing a competitive programming question)
AP: Tell me the ones we did in class.
I haven't attended those classes, so I just told her the ones I knew.

After a couple more infuriating questions, which themselves sounded right from a book published in the 90's, she gave me 10/15.

This is what's wrong with India's Education system, even the teachers know only the stuff mentioned in the course hand-outs. Forget brownie points, you get screwed over by the teachers for actually knowing stuff and using it.

genuine question: does @dfox read each and every rant? I get his ++ for almost every rant and his ++'s are around 8000 😱

You wanna know what the fuck we did in our goddamn code.org class today, wait no, the last whole fucking week. YES OR NO QUESTIONS. I GET BINARY IS FUCKING 0'S AND 1'S. FOR GOD SAKES I KNOW BINARY. I EVEN KNOW FUCKING TERNARY. AND. YOU KNOW WHAT TEACHER ? EVERYONE ELSE COULD LEARN BINARY IN FIVE GODDAMN MINUTES. "Is code.org worthy of being kicked in the ass and tied up on a railroad when the trains coming?" Is a perfect binary question. This whole fucking class I feel like I'm in an english class for five year olds in spain. HEY TEACHER I DON'T CARE IF BILL GATES OR MARK SUCKERBURG OR BARAK OBAMA OR GODDAMN CHRIS BOSH SUPPORTS IT. ITS FOR THERE FUCKING REPUTATION. PEOPLE WITH HALF A BRAIN KNOW THESE PEOPLE DON'T GIVE A FUCK. THEY EACH HAVE HUNDREDS OF MILLIONS OR EVEN BILLIONS OF DOLLARS, BUT THEY ALL CHOSE TO USE A FIVE DOLLAR MIC JUST TO FUCK WITH US. EVERY TIME I WALK IN THAT CLASS I FEEL DEGRADED LIKE I'VE BEEN PUT BACK IN PRESCHOOL. THANK YOU TEACHER, I ALWAYS WANTED TO LEARN BINARY TO MAKE MY FUCKING SIMPLE JAVASCRIPT APP AS MY FINAL PROJECT FOR THE REST OF THE YEAR.

I was recently interviewing a fresh college graduate. According to his resume, he had practically invented machine learning. He eats kaggle datasets for breakfast and was all set to invent a cure for cancer with deep learning. And then, I ask him a simple question. What is 's' in 'https' and he says... "simple".

A question for all the front-end developers of devRant. How the fuck do you get a really good color scheme for a website?

P. S. I am not a front-end dev so please simple words

My company decided to reinvent the wheel by writing its own queue system instead of using the existing message queue service.

And it uses plain PHP with exec() to run the workers.

Where do we store the job? We use mongoDB which is already used in our existing projects. We can query the collection/table each time the queue service start, execute the jobs, and let it exit if there's no job anymore. Don't worry, systemd will start the queue service again once it exits.

How to monitor the workers? Yep, we use ps and grep to check if the worker's PID still exists in the OS.

What about error stack traces? Nice question, we redirect the stdout and stderr when exec()-ing into a file.

What about timeout? We don't need it, let's just assume no one is going to write while(true).

It works flawlessly! /s

The feeling when random dudes downvote a question, because a guy who finally earned some points on SO dared to format the code with `<code>`<br> He pasted code, log, even explained a little bit and ~500 point guy even flags it like _unclear_ although there's clearly visible import error.

I mean... as an answerer or moderator, I'd be damn ashamed for such behavior! I have absolutely no problem kick a person with words + explanation in my answer or comment, so that (s)he remembers to ask better questions and feels bad about that, because nooby questions are already answered so many times there.

But to downvote because of formatting even if you have a permission to edit and a flag for low quality or because you can't read ~40 lines of log makes you just a retard and hurt the whole remaining community of guys like me who find time to sit there and answer questions to help another people.

// Fist Rant :S

When you go to sleep late the day before studying hard for the exam of graph theory and when you see the test equally not know how to answer any question :(

I'm facing something really strange, in a coffee shop I go to usually, all downloads even if from terminal download speed is at best 200KB/s and at worst 50KB/s, but there is this game armored warfare, it reaches 2MB/s download speed on the same connection, while at home everything goes to max 200KB/s.

My question is, how do the devs at armored warfare do this? use max connection speed or are there any configs need to be changed so I can reach max speed in any downloading?

Hey DevRant Fam ❤️ hope everyone is well as always! It’s Sunday here in dull weather Sydney!, i was thinking bout this for awhile now, now surely most of us time to time use Stack Overflow for help and it works!.

Though, thats not the issue :-), my first time using it as a newbie wasn’t so great so to say, I’ve noticed that the people over at S/O can be quite rude such as they would downVote my question and also not comment why they have downvoted it :-(.

I’d love to know what you guys think, funnily enough I’m using DevRant much more than FB itself 😅, anyways guys hope you’re all having a great one!

Best wishes ❤️

Final project senior year...
Mistake 1: Chose a project suggested by the prof, who did not initially make it obvious that the project beneficiary would be a personal friend of his.
Mistake 2: Nine of us thought this project looked cool and all signed up for it.
Mistake 3: Looked at the code-behind provided for us and discovered that the web-app we were building was... programmed in Java, using StringBuilder to append HTML, CSS, and JavaScript and create its webpages. Which was then decoded and built into a webpage using some obtusely designed compiler.
Mistake 4: Decided to question the reasonability of said project to the prof.
Mistake 5: Did not quit the project as a group and do something else

We all graduated, I think, but a lot of C-'s were had. Fuck that class.

I just can't stress enough how fascinated I am by biology and biochemistry.

I mean, we, who call ourselves engineers, are no more but a gang of toddlers having a blast with jumbo legos on Aunt Lucy's dining room carpet on a sunny Sunday afternoon. Our solutions using "modern tools" and "modern engineering" are mere attempts to *very* remotely mimic what beautiful and elegant solutions are around us and inside of each of us.

IC/EC engines, solar batteries, computers and quantum computers, spaceships and ISSes, AI/ML, ... What are they? just the means to leverage what's been created all around us to create something that either entertains us, encourages our laziness or helps us to look at the other absolutely fascinating engineering solutions surrounding us so we could try and "replicate" their working principles to further embrace our laziness and entertain us.

Just look at the humble muscle - a myofibril made out of actin and myosin. The design is soooo simple and spot on, so elegant and efficient, the "battery" and signalling system are so universal and efficient.

Look at all those engineering miracles, small and big. Look how they work, how they leverage both big and small to create holistic, simplistic and absolutely efficient mechanisms. And then come back to me, and tell me again that all these brilliant solutions came out of nothing just by an accident we call "evolution".

How blinded by our narcissism are we to claim that there can't be a grand designer of any kind, that there's nothing smarter than us and that the next best thing than us is an incomprehensible series of accidental mutations over an unimaginable amount of time?

I mean.. could it be that someone/something greater than us created us and everything around us? naaaah.. we are the crown jewel of this universe. Everything else must be either magic or an accident. /s

Don't read this as yet another crazy-about-God person's ramblings. I'm not into religion fwiw. But science has taught me enough critical thinking to question its merit. Look at it all as engineers. Which is more probable: that everything around us happened by an accident or that someone/something preceding us had a say in the design?

At 5:35 Gilfoyle says: "In order to hold that much data we would have to go RAID 0. [...] If we lose even one platter, we lose Melcher's data. Permanently."
But my question is: Why use RAID at all? Just storing the data without RAID would reduce the complexity, and if one disk fails, only the data on that one disk is lost. Also, I doubt speed is a priority at that point, since the whole thing is running on a home broadband connection, which something like a WD Gold data-center-harddrive (200+ MB/s) can easily max out.

Also, wouldn't it be easier to pay the broadband bill out of their own pocket, instead of moving tons of server equipment to Stanford?

Alright, I’ve got a question for some of you who may have felt this way or currently are feeling this way.

I’m burnt out. I hate my job(s), I hate computers, technology, programming, etc. Honestly, at my primary job because shit is so bad, I haven’t even set an alarm clock to wake up in the mornings for the simple fact that I just don’t give a fuck anymore. My direct supervisor is the same way. This place is falling apart and honestly I’m welcoming it.

I’ve grown up with computers my whole life. When I was younger my brother would hack and tamper with shit just to test the limits. To see what he and his machine were capable of. My dad, he was always taking computers apart, anything that had a board, it was at one point taken apart to see how it worked, and when put together; always worked. They liked modifying and testing the limits of things... the shit I use to enjoy...

I guess what I’m trying to ask is, how do you gain a passion back for something that has faded away over a period of time... I truly hope I haven’t forever lost a passion for computers and every subclass under it, but I fear as though I have... How do you guys get it back?

Audiophiles here?

My Beats In-ear earphones just died, after 3 years of pretty frequent use. The cable is broken and one side is dead and the other side is flickering. Now I am looking for a replacement. And I hope that someone here can suggest me something that fits my needs :s
First question would be wireless or cable. I am not to sure yet, I think I'd prefer cable because I don"t need to charge them and the possibility of loosing them is not as big. However I am open to wireless earphones as well, since they are pretty good to listen to music during workout.
I want my earphones to have deep bass and clear highs.
One of the most important aspects is durability. If its a cable earphone, I would prefer something with strong durable cables, nothing flimsy that breaks again in a short time.
Oh yeah and the price shouldn"t break the bank, I am thinking about something <100 euros.

What would you guys recommend me?

So while exploring some new ideas, I decided to figure out if I could use variables in the known set to determine the bounds of variables in the unknown set.

The variables in question are algebraic identities derived from the semiprimes, so you already know where this is going.

The existing known set is 1194 identities.
And there are, if I recall, roughly two dozen unknowns.

Many knowns have the unknowns as their factors. The d4 product set for example is composed of variables d4a, d4u, d4z, d4z9, d4z4, d4alpha, d4theta, d4omega, etc.
The component variables themselves are unknown, just their products are known. Anyway.

What I've found interesting is if you know the minimum of some of these subsets, for example d4z is smallest out of the d4's for some semiprimes, then you know the upperbound of both the component variables d4 and z.

Unless of course either of them is < 1.

So the order of these variables, based on value, changes depending on the properties of the semiprime, which I won't get into. Most of the time the order change is minor, but for some variables they can vary a lot between semiprimes, rapidly shifting their rank in the known set. This makes it hard to do anything with them.

And what I found myself asking, over and over again, was if there was a way to lock them down? Think of it like a giant switch board, where flipping one switch lights up N number of others, apparently at random. But flipping some other switch completely alters how that first switch works and what lights it seemingly interacts with. And you have a board of them thats 1194^2 in total. So what do you do?

I'd had a similar notion a while back, where I would measure relative value in the known set, among a bunch of variables, assign a letter if the conditions were present, and generate a string, called a "haplotype."
It was hap hazard and I wrote a lot of code to do filtering, sorting, and set manipulation to find sets of elements in common, unique elements, etc. But the 'type' strings, a jumble of random letters, were only useful say, forty percent of the time. For example if a semiprime had a particular type starting with a certain series of letters, 40% of the time a certain known variable was guaranteed to be above a certain variable from the unknown set...40%~ of the time.
It was a lost cause it seemed.

But I returned to the idea recently and revamped the entire notion.

Instead what I would approach it from a more complete angle.
I'd take two known variables J and K, one would be called the indicator, and the other would be the 'target'.
Two other variables would be the 'component' variables (an element taken from the unknown set), and the constraint variable (could be from either the known or unknown set).

The idea was that relationships between the KNOWN variables (an indicator and a target variable) could be used to indicate the rank relationship between the unknown component variable and the constraint variable.

You'd think this wouldn't work either, but my intuition was there were so many seemingly 'random' rank changes of variables in the known set for any two semiprimes, that 1. no two semiprimes ever shared the same order for every variable, and 2. the order of the known variables had to be leaking information about the relationships of the unknown variables.

It turns out my intuition was correct.

Imagine you are picking a lock, and by knowing the order and position of the first two pins, you are able to deduce the relative position of two pins further back that you can't reach because of the locks security features. It doesn't let you unlock the lock directly, but by knowing this, if you can get past the lock's security features, you have a chance of using information about the third pin to get a better, if incomplete, understanding about the boundary position of the last pin.

I would initiate a big scoring list, one for each known element or identity. And then I would check it in tandem like so:

if component > constraint and indicator > target:
indicator[j]+= 1

This is a simplication, but the idea was to score ALL such combination of relationship, whether the indicator was greater than the target at the same time a component was greater than a constraint, or the opposite.
This worked out to four if checks and four separate score lists.

And by subtracting one scorelist from another, I could check for variables that were a bad fit: they'd have equal probability of scoring for example, where they were greater than the target one time, and then lesser than it for another semiprime.

So for any given relationship, greater or lesser between any unknown variable and constraint variable, I could find any indicator variable and target variable whose relationship strongly correlated to the unknown's.

Any JavaScript developers out there willing to help me out with something?

I have an interview question that I like to ask candidates that no one ever seems to get right. But, to me, it seems pretty basic, so I expect MOST JavaScript developers at almost any level of expertise to get it, and I like it generally because it demonstrates some core knowledge of JavaScript concepts and syntax.

But I want to verify that my feelings about it are reasonable, because give how few ever seem to get it right (and I'm talking across literally hundreds of interviews, MAYBE 2 people have ever gotten it right), I'm starting to wonder if I'm right or not.

Look at this code, and then answer the question after. Please do so off the top of your head and without testing anything since that's normally the experience a candidate would have. I'll give the answer after some time for anyone who gets it wrong but is curious.

But this isn't about YOU getting it right or not, and it's not about whether it's the best way to do something in JavaScript or anything like that, it's just about whether it's a reasonable question and whether my expectation that MOST JavaScript developers should get it right is fair.

const O = {
sayHello : function() { alert("Hello"); }
};
const S = "sayHello";

Question: using ONLY the variables O and S (and you MUST use both), write code that executes the sayHello function.

Thanks!

They ask me if I have girlfriend(s), I speechless for maybe 5-10 second, then they told me the answer is define my sallary..

Is that normal / common question.?

Any Windows Sysadmins here? I have a question for you - How do you do it?

I only very rarely have to do something that would fall under "Windows System Administration", but when I do... I usually find something either completely baffling, or something that makes me want to tear our my hair.

This time, I had a simple issue - Sis brought me her tablet laptop (You know, the kind of tablets that come with a bluetooth keyboard and so can "technically" be called a laptop) and an SD card stating that it doesn't work.

Plugging it in, it did work, only issue was that the card contained file from a different machine, and so all the ACLs were wrong.

I... Dealt with Windows ACLs before, so I went right to the usual combination of takeown and icacls to give the new system's user rights to work with the files already present. Takeown worked fine... But icacls? It got stuck on the first error it encountered and didn't go any further - very annoying.

The issue was a found.000 folder (Something like lost+found folder from linux?) that was hidden by default, so I didn't spot it in the explorer.

Trying to take ownership of that folder... Worked for for files in there, safe for one - found.000\dir0000.chk$Txf; no idea what it is, and frankly neither do I care really.

Now... Me, coming from the Linux ecosystem, bang my head hard against the table whenever I get "Permission denied" as an administrator on the machine.

Most of the times... While doing something not very typical like... Rooting around (Hah... rooting... Get it?! I... Carry on) the Windows folder or system folders elsewhere. I can so-so understand why even administrators don't have access to those files.

But here, it was what I would consider a "common" situation, yet I was still told that my permissions were not high enough.

Seeing that it was my sister's PC, I didn't want to install anything that would let me gain system level permissions... So I got to writing a little forloop to skip the one hidden folder alltogether... That solved the problem.

My question is - Wtf? Why? How do you guys do this sort of stuff daily? I am so used to working as root and seeing no permission denied that situations like these make me loose my cool too fast too often...

Also - What would be the "optimal" way to go about this issue, aside for the forloop method?

The exact two commands I used and expected to work were:
takeown /F * /U user /S machine-name /R
icacls * /grant machine-name\user:F /T

!rant && POLL

A lot of people are asking for poll feature. There have been many debates. While reading those, I even thought we should probably ask a debate feature before poll.

Anyway you can actually create poll rant. Just gotta be creative and a bit organized like adults (hope we all are).

1) you ask your poll question as rant
2) you enter your poll choices as comments
3) people ++ their favorite choice comment (s)

Of course this is not a poll-poll feature so there are many lacking functions. But at least it works to certain extent.

Eg Question : What is your OS?

I feel like writing or telling people about the time I jumped from Windows 7 Ultimate and jumping to Windows 10. (I'm not against 10, but I'm never updating after what had happened to me)
It all starts when none of my games will play due to a possible issue with my graphics card. I look up "3D source game bug" and not many results pop up. I go on Microsoft's Qna areas and ask this question but to my surprise nothing they say would make sense. "Clean the pins of your graphics card, make sure you verify the games on Steam". I verified the games and they checked out as perfectly fine. I don't have access to my graphics card because this is a laptop, sadly not a tower.
Two months pass and my computer is already showing signs of stress, like it didn't want to live in a sense. It was three times slower than when I was on Windows 7 and it was unallocating areas of my main hard drive where I could make virtual hard drives.
Instantly I start looking up Linux distros and find Linux Mint. 17.3 was the current version at the time. I downloaded it and burned it onto a DVD-rom and rebooted my computer. I loaded into the disc and to my surprise it seemed almost like Windows 7 apart from the Linux part. I grab my external hard drive and partition it to hold the Linux distro and leave it plugged in incase Windows 10 does actually fail.
On December 19, a few months after Windows 10 had released. I start my laptop to try and continue my studies in video game development. But to my surprise, Windows 10 had finally crashed permanently. The screen flickered blue and black, and an error box saying Loginui.exe failed to start. I look at it for a solid minute as my computer had just committed suicide in a sense.
I reboot thinking it would fix the error but it didn't. I couldn't log in anymore.
I force shutdown the laptop and turn it back on putting it into safe mode.
To my surprise loginui.exe works and I sign in. I look at my desktop, the space wallpaper I always admired, the sound files, screen shots I had saved.
I go into file explorer and grab everything out of my default hard drive Windows was installed on. Nothing but 400gb got left behind and that was mainly garbage prototypes I had made and Windows itself. I formatted my external hard drive and placed everything on it. Escaping Windows 10 with around 100GB of useful data I looked at the final shutdown button I would look at.
I click it and try to boot into normal Windows 10. But it doesn't work. It flickers and the error pops up once more.
I force it to shutdown and insert the previous Linux Mint disc I made and format the default hard drive through Linux. I was done. 10 gave me a lot of shit. Java wouldn't work, my games has a functional UI but no screen popped up except a black abyss and it wouldn't even let me try to update my graphics card, apparently my AMD Radeon 5450 was up to date at the AMD Radeon 5000's.
I installed Linux Mint and thinking the games would actually play I open steam and Launch Half-Life 2 to check if Linux would be nicer to me than Windows 10 had been.
To my surprise the game ran. The scene from Highway 17 popped on screen and the UI was fully functional. But it was playing at 10-15fps rather than the usual 60-70fps. Keep look at my drivers and see my graphics card isn't in use. I do some research and it turns out I have a Hybrid Laptop.
Intel HD Graphics and an AMD Radeon 5450 and it was using the Intel and not the AMD. Months of testing and attempts of getting the games to work at high frame rates pass and the Damn thing still functions at a low terrible fps. Finally I give up. I ask my mom for a Windows 7 disc and she says we can't afford it. A few months pass and I finally get a Windows 7 installation disc through money I've saved up. Proudly I put it into my optical disc drive and install it to my main hard drive deleting Linux completely. I announced to all my friends my computer was back in working order and I install everything I needed, Steam, Skype, Blender, and Unity as well as all my games. I test Half-Life 2 and it's running exceptionally smoothly, I test Minecraft at max settings and it's working beautifully. The computer was functioning properly once again and my life as a developer started as I modeled things and blender, learned beginners C# and learned a lot of Batch. Today the computer still runs at a great speed and I warn others of what happened to me after I installed Windows 10 to my machine if they are thinking of switching from 7 or 8 on an older machine.
Truly the damage to my data cannot be undone. But the memory of the maintenance, work, tests, all are a memory of how Windows 10 ruined me and every night before the one year anniversary of Windows 10's release, I took out the battery of my laptop and unplugged it from the a.c. power, just so Windows 10 doesn't show it's DLLs, batch scripts, vbs scripts, anything on my computer. But now, after this has happened and I have recovered, I now only have a story to tell

My Data Communication & Computer Networks (DCCN) teacher was the best teacher I've seen.

Teaching can be super hard. You're one against like sixty others who aren't interested in being there. To make that good learning environment, making the subject interesting etc, it not easy. Some justify that, "I can only bring the horse to the water" & proceed to just regurgitate whatever is on the book. Others cross question you & impose punishments - try to make you learn by fear.

But my DCCN teacher - she had the right balance between strictness & humour. So kids took her seriously (did homework, weren't late), yet never feared her - we felt comfortable asking doubts/questions.

She had some good tactics, like asking us to teach certian chapters - that made us learn better. She would revise them in the end also, incase we missed anything.

My best moment with her was when I scored the highest in my internals. She picked up my paper & showed the class - "see? Just two pages & he scored so much". There's was always those students who pump out a lot of stories/essays or whatever that comes to their mind about the topic in question. Lots of teachers just blindly give marks - "oh, s/he wrote this much, so it must be right".

But my DCCN teacher had zero tolerance for garbage. If you're wrong, you're wrong. Some even believe that the number of marks = number of lines you have to write!! Doesn't matter what you write. So, I was super glad when this teacher upped the standards.

let's create a site of Creative-Commons-licensed meme templates. Who around here can host some stuff?

So today i learn`t SASS and im impressed but here`s the damn question , What do ya recommend SASS or LESS

Note: I have deleted my previous version of this question as I found it lacking crucial information and therefore being prone to misunderstandings.

Question : In C/C++ you can position the keyword 'const' either left or right of the left-most type specifier. Which variant do you prefer?

I ask that because I'd like to hear your opinion. Although I have been working with C over three decades now, I only learned this a couple of years ago. After some experimentation I decided for myself, that I like the placement to the right more. Although the positioning to the left is taught in literally every book and course, the original placement suits me better.

One reason, of many, is the listing of many member variables in structs or classes. To have them nicely aligned, I always had to put 'const' either on the previous line or put in extra indention to everything non-const. That was quite irritating sometimes.

Another, and my main reason is, that when reading from right to left, the rhs variant just makes more sense than the lhs variant. Reading from left to right almost never makes much sense without straining your eyes. But that is, of course, highly subjective.

This is even more so if you have pointers. The 'const' keyword modifies the type identifier(s) to the left. So if the 'const' is (anywhere) left of the '*', the data is const. If the 'const' is right of the '*', the pointer address itself is const. The same applies to references.

Examples, read right-to-left:
int* const i; // i is a const pointer to int data
int const* i; // i is a pointer to const int data
int const* const obj; // i is a const pointer to const int data

The "classical" or "taught" way, that is found almost everywhere would read, still right-to-left:
int* const i; // i is a const pointer to int data
const int* i; // i is a pointer to int data const
const int* const obj; // i is a const pointer to int data const

Not only that the second "lhs" form reads worse, it also looks worse. In my opinion, the first "rhs" variant makes it simpler to quickly determine that we are dealing with three ints, while on the second "lhs" variant, one has to first get past the 'const' keywords.

I know that this is not only a matter of taste, but of course of agreement, too. You can not just go and switch the 'const' placement in long standing projects. That would surely piss of a lot of people. Or even cost you your job.
But I like to know what you people think and why.

Thanks a lot in advance!

When Do You Stop Taking Responsibility?

Let me clarify by describing four scenarios in which you are tasked with some software development. It could be a large or small task. The fourth scenario is the one I'm interested in. The first three are just for contrast.

1. You either decide how to implement the requirements, or you're given directions or constraints you agree with. (If you hadn't been given those specific directions you probably would have done the same thing anyway.) **You feel accountable for the outcome**, such as whether it works correctly or is delivered on time. And, of course, the team feels collectively accountable. (We could call this the "happy path.")

2. You would prefer to do the work one way, but you're instructed to do it a different way, either by a manager, team lead, or team consensus. You disagree with the approach, but you're not a stubborn know-it-all. You understand that their way is valid, or you don't fully understand it but you trust that someone else does. You're probably going to learn something. **You feel accountable for the outcome** in a normal, non-blaming sort of way.

3. You're instructed to do something so horribly wrong that it's guaranteed to fail badly. You're in a position to refuse or push back, and you do.

4. You're given instructions that you know are bad, you raise your objections, and then you follow them anyway. It could be a really awful technical approach, use of copy-pasted code, the wrong tools, wrong library, no unit testing, or anything similar. The negative consequences you expect could include technical failure, technical debt, or significant delays. **You do not feel accountable for the outcome.** If it doesn't work, takes too long, or the users hate it, you expect the individual(s) who gave you instructions to take full responsibility. It's not that you want to point fingers, but you will if it comes to that.

---

That fourth scenario could provoke all sorts of reactions. I'm interested in it for what you might call research purposes.

The final outcome is irrelevant. If it failed, whether someone else ultimately took responsibility or you were blamed is irrelevant. That it is the opposite of team accountability is obvious and also irrelevant.

Here is the question (finally!)

Have you experienced scenario number four, in which you develop software (big as an application, small as a class or method) in a way you believe to be so incorrect that it will have consequences, because someone required you to do so, and you complied *with the expectation that they, not you, would be accountable for the outcome?*

Emphasis is not on the outcome or who was held accountable, but on whether you *felt* accountable when you developed the software.

If you just want to answer yes or no, or "yes, several times," that's great. If you'd like to describe the scenario with any amount of detail, that's great too. If it's something you'd rather not share publicly you can contact me privately - my profile name at gmail.com.

The point is not judgment. I'll go first. My answer is yes, I have experienced scenario #4. For example, I've been told to copy/paste/edit code which I know will be incomprehensible, unmaintainable, buggy, and give future developers nightmares. I've had to build features I know users will hate. Sometimes I've been wrong. I usually raised objections or shared concerns with the team. Sometimes the environment made that impractical. If the problems persisted I looked for other work. But the point is that sometimes I did what I was told, and I felt that if it went horribly wrong I could say, "Yes, I understand, but this was not my decision." *I did not feel accountable.*.

I plan on writing more about this, but I'd like to start by gathering some perspective and understanding beyond just my own experience.

Thanks

Any technical cofounders here? I've been offered to be a technical co-founder for a new venture. This is a venture that has the same founding team as the startup I'm working with for last 3 years or so. The current venture may be acquired in the near future with the founding team exiting.

Now my question (s) are these:
1. I know the team. We're friendly. But until now the relationship has been that of an employer-employee. What all should i consider before taking this up?
2. Since founders generally take up salaries only what is required for them to sustain. It would mean a financial cut for me too. So I'm stuck in the dilemma of moving towards an entrepreneurial route vs if it fails and I've to work again i may have to start off with a lower salary in the future.

I'm a risk taker (some call it seeker) when it comes to that. Looking forward for some helpful suggestions.

Question: exactly got how necessary is a degree anymore for programming positions?

Okay, so this is more like a question, than an actual rant, but what site(s) do you freelancers use?
Lately i have some serious free time, and thought, why not try to make some side-money?

[Question]
What type of amplifier circuit would I need to power a 60w 8ohm speaker or can you recommend any prebuilt amplifier boards ?

[TLDR;]
I spotted the below stuff while cleaning out my junk cupboard and thought it might be a fun side project to convert them into a portable bluetooth speaker since the earphones are shit anyway and I've always wanted to learn more about amplifiers.

The only question remaining is how to amplify the headphone output signal enough to power the speaker. I plan on either using cells from old laptop batteries or a motorbike battery as a power supply so input voltage would be roughly 10-12v.

The speaker is from a set I salvaged from an old 80's hifi and has excellent sound quality, would mounting the components inside it have a large negative effect on it's sound?

Also although I would prefer to make my own amplifier board as a learning experience the goal is to have a portable speaker with good sound quality... is this something I'm likely to get from my first attempt at an amplifier or should I rather get a ready made board?

Hey guys, this is my first rant/question so be gentle (please).

I've heard from my friends that there are some people who are really into privacy etc. So can you recommend best VPN(s) out there?

A beginner in learning java. I was beating around the bushes on internet from past a decade . As per my understanding upto now. Let us suppose a bottle of water. Here the bottle may be considered as CLASS and water in it be objects(atoms), obejcts may be of same kind and other may differ in some properties. Other way of understanding would be human being is CLASS and MALE Female be objects of Class Human Being. Here again in this Scenario objects may differ in properties such as gender, age, body parts. Zoo might be a class and animals(object), elephants(objects), tigers(objects) and others too, Above human contents too can be added for properties such as in in Zoo class male, female, body parts, age, eating habits, crawlers, four legged, two legged, flying, water animals, mammals, herbivores, Carnivores.. Whatever.. This is upto my understanding. If any corrections always welcome. Will be happy if my answer modified, comment below.

And for basic level.

Learn from input, output devices

Then memory wise cache(quick access), RAM(runtime access temporary memory), Hard disk (permanent memory) all will be in CPU machine. Suppose to express above memory clearly as per my knowledge now am writing this answer with mobile net on. If a suddenly switch off my phone during this time and switch on.Cache runs for instant access of navigation,network etc.RAM-temporary My quora answer will be lost as it was storing in RAM before switch off . But my quora app, my gallery and others will be on permanent internal storage(in PC hard disks generally) won't be affected. This all happens in CPU right. Okay now one question, who manages all these commands, input, outputs. That's Software may be Windows, Mac ios, Android for mobiles. These are all the managers for computer componential setup for different OS's.

Java is high level language, where as computers understand only binary or low level language or binary code such as 0’s and 1’s. It understand only 00101,1110000101,0010,1100(let these be ABCD in binary). For numbers code in 0 and 1’s, small case will be in 0 and 1s and other symbols too. These will be coverted in byte code by JVM java virtual machine. The program we write will be given to JVM it acts as interpreter. But not in C'.

Let us C…

Do comment. Thank you

Generally have great experience with our management.
I work at a scale-up, so I've had some run-ins with the founder shifting priorities too often in the early days, but he's got enough notion of tech to understand when we're telling about the why(not)s of what we can and can't do
A while back we got a product owner/manager/scrum master and he's great too. I've had times when he put pressure on making deadlines when it was really not helping, but overall great guy with a lot of empathy and respect for his team.

But recently I've been starting to feel like we (the dev team) are getting more and more excluded from the decision-making process of the features & designs that we're going to be working on. We used to have a say in what we felt like was a good idea for a feature or a design, but it feels to me like we don't get asked that question any more of late...

Not sure if I'm imagining it, or overreacting to a logical (possibly positive?) evolution in our development workflow...

Can someone explain to me the need of a "technical management"? I know my question is naive, but try to explain it like to kindergarten kid.

Case 1. When team is good, and has a good tech leader(s) then the software director/manager makes more harm with his silly ideas, pompous cliche "calls to arms" etc.

Case 2. On the other hand, when software team is shit, it means that the management is responsible for assembling such team. Then it further means that they can't distinguish impostors from really good talents, which leads to bad quality, missed deliveries, bugs, frustrations, etc.

I saw many times when good technical lead (aka architect, staff, principal) made a positive difference. But I NEVER EVER saw that things were bad and "manager/director" made a positive change. This concept is soooo flawed....

... any one explain please?

Today i got so fucking depressed and discouraged because whenever i tell people "i am a software engineer" or "programmer" especially fking girls they just fuckin leave. They dump you. Imagine seeing someone with both ur eyes, both of ur shits seeing someone go from high interest and then watch their interest drop

Questions more then a rant...

I've moved from being a lead on imploring DevOps and Agile practices in a large Telco to now working for a security consultancy... The team I'm with are s*** hot when it comes to SecOps (which is why I changed jobs) and I've been hired to he the automation and working practice expert on the team. Already got some of them learning Ansible which is a great start!

I've got delivery now being pushed to Git and all client work being tracked in Jira and properly documented and collaborated through HipChat and other CI tools on the way....

My question is this... Does anyone have some awesome resources to teach people Git, Jira, Jenkins, etc. quickly without forking or branching out on expensive training? Focus on being a technical but consultative team. Ideally just wanna pull some awesome guides and make. My own commits on them for the team... Please fire a story or epic away!

Okay, stupid question...

Is there are standardized api for manipulating text terminals on linux distros? Something similar to win32's consoleapi.h
Or is there a library that provides such an api?

Quick Plesk config question...

Been getting open_basedir() notices in the WordPress logs, and frankly it's flooding the log right now. Sample below:

[24-Feb-2019 07:05:19 UTC] PHP Warning: file_exists(): open_basedir restriction in effect. File(/var/www/vhosts/webspacedomain.com/SiteInstallDirectory/wp-content/db.php) is not within the allowed path(s): (/var/www/vhosts/webspacedomain.com/:/tmp/) in /var/www/vhosts/webspacedomain.com/SiteInstallDirectory/wp-includes/load.php on line 397

Checking the settings for open_basedir in the domain's PHP settings, it's currently set to the following default value:

{WEBSPACEROOT}{/}{:}{TMP}{/}

By my read, that **should** be granting permission to the directory. I just checked it against the setting on the dev server (which doesn't report this error), and it's configured in the same manner. Only difference between Dev environment and this one is that the one in Dev is in vhosts/webspacedomain.net/DEV instead of just vhosts/webspacedomain.net

Is there something I'm missing here?

Hey Devs, question.

When job hunting, what would be your preferred option(s).

1. Contacted directly by the hiring company's HR
2. Applying via recruiting agents
3. Applying directly on companies job site
4. Referrals

Oh china, you always know how to snap me out of long stints of mundane and/or annoying, chore-esq work.
//...and letting me excuse a 10min, otherwise purely wrong procrastination down a current political rabbit hole

I gotta say, at least in china they are bold enough to put their image and identity on whatever they make... but in that 'im selling pseudo-sex, not because im sexy--just the opposite, so you know I relate' way.

Side note: i got an automated spam call survey yesterday*... it ot got to the 1st (of claimed 3) question.. which had a surprising amount of actual reiterations before looping... it was determined to get opinions(and totally incept the lemmings, soccer moms and politically ignorant into their stance, plus intense rage/disgust/dreams of standing on a soap box and fighting about this new issue they were totally unaware of.)... about this actively serving, politician's demand that china sell tiktok or totally stop allowing any operations/use on american soil... because of the heavily implied heinous nature of controlling and twisting society via media to it's explicitly declared communism... even directly called china, as a whole, communists, with impressive dramatics (and i coached public speaking hs and college kids then over a decade of business consulting, typically involving coaching vocals and implicit vocab)

I actually listened to it because it's what a typical subject, brought out of the koolaid fog, would view as ridiculously ironic(assuming they knew the actual, and therefore inherently ironic, def if irony... most dont. It's disturbing)... but it you have decent common sense, and dont emotionally view your entirety as wrong/broken/needing to be fixed in a cult-like manner, it's the oposite of irony. History of/and politics pull this crap all the time. It still works.

It reminds me of how my moniker, awesomeest, came about. In 3rd grade i realised that even adults, knowing they were chatting with an 8yr old, even if they knew/used the correct spelling of a, less common, term... if i misspelled it as if i thought it was right, theyd actually change their spelling to match (in perpetuity) albeit my vocab was easily high school level by then...likely at least in part to my flawless(aka blind/ignorant) demeanor of confidence that whatever i said/thought was totally correct, as a matter of fact. Not like the insecure ppl trying to prove something

I used to find it so comical... now it's just sad.

This bs automated political spam/manipulation is the modern version of i remember of kids farting in the late 90s... the culprit quickly accusing someone else of their offense, but even extra immature kids 25+ yrs ago figured that out... and even made the retort a catchy rhyme..."the one who smelt it, dealt it"

*i basically programmed in a counter attack/something akin to immature passive aggressive ' who"s really the one wasting the other's time and resources now?!? Ha!' ...odd numbers automatically go into a sort of echo chamber instead of ringing, with a manual escape to actually ringing/calling prompt built in.

I can listen in at any time without it having any effecf/sound too.

I'm curious if anyone participates in these minor acts of terrorism to complete an unrequested, intrusive, and human-less format of a proclaimed opinion poll? And if you do, are you honest? Why do you do it?

Annoyance at spam aside... the real victim I mentally mourn, and view it's method of demise akin to a cardinal sin (assuming religion...blah blah)... is the data! I <3 data... good, unobscured, not contrived, simple, pure, raw data... killed before its birth :'(

The charging port on my Galaxy S8 is messed up and is constantly disconnecting while charging, which results in the phone either slow charging or just got charging at all.

I thought I got the monthly phone insurance through Verizon and I was just gonna pay the deductible and get the phone replaced, but apparently I don't actually have the insurance even though I could've sworn I did. So that option is out the window.

So now I'm left with 3 other options:

1.) Pay $100 to get the charging port repaired at a local repair shop
2.) Pay off the remaining $200 I owe on the phone and get a phone upgrade from Verizon (because I am due for an upgrade)
3.) Get the upgrade but still keep my current phone on my plan and just pay the remaining $200 off monthly like I have been since I got the phone, except I'd also be paying for a second phone. Which is fine, because either way I'd be paying the $200. It's just a question of paying it in a lump sum or paying it monthly. Either works for me, it's $200 both ways

The downside of upgrading now is that I wouldn't be able to get the Galaxy S10 when that comes out, and that's what I've been waiting for as I prefer the smaller Galaxy S phones over the Galaxy Notes.

I suppose I could trade in whichever phone I get when the S10 comes out, but that would be a huge hassle and I'd have to pay at least 50% of the phone off in order for it to be eligible for trade-in

A question about Angular components. Can a component become a member of another component?

Let' s say I have a sensorReading component that looks like these green boxes. I only want 4 of them in app-component(default one). How can I create 4 of these inside app-component and access their properties and methods from app-component.ts script?

I can create 4 of them in app-component.html with ngFor but how can I access elements of these sensorReading components I created with ngFor? Members are sensorType, value and unit as you can see.

tldr: I am looking for recommendations for a basic website for my parents. GOTO question;

Pre-Story:
My parents have a small (offline) business. They have a website to give some general information and list their weekly offers.
When I felt that what has come out of the website-building tool (you know, clicky clicky stuff) looked a bit too early 2000's and is a total ripoff for what you get (almost 20€ per month), I created something with Google Sites for them. Feel free to roast me, but web development is not my field and now it looks much more modern, is mobile friendly and does what it is supposed to do. Weekly offers are edited in a google sheets file, which is embedded in the website. Not great, but this way my mom doesn't have to deal with editing a tables on the page - trust me, it won't look good. This also meant they could downgrade the hosting package to discard the clicky-tool and just the domain (maybe 1€ per month). The website itself is hosted for free by Google.

Some time ago GDPR became a thing and then I was tasked to have a look at it. (side note: I don't want to rant about being responsible for it, that's fine. My parents don't really ask me to do a lot for them.) You can't enter any data on the website, it's just very basic stuff and data protection wise there's just the "usual" stuff (cookies, embedded tools, logs). I added another site with a halfway complete privacy policy. Regarding the whole cookie issue (do not enforce unnecessary cookies) I couldn't find an easy solution. It's not 100%, but what can you really expect from a small business like this? I've seen worse.

Now to the question:
Can you recommend a good alternative to the current solution (Google Sites)?
It should be cheap (<3€/month incl. domain) and my parents should be able to make some basic changes (just text in predefined locations). I am not afraid to get my hands dirty - I can deal with some HTML, CSS, JS - but I don't want to sink a lot of time into this. No need for analytics or the like. Maybe a newsletter would be cool (with the weekly offers), but that's just a random thought of mine and definitely not necessary.

Thanks for reading :)

Don't really know if this is an appropriate question to throw on here but what the heck.

So I'm thinking about trying to look into the dating scene again. I'm in my late 20's and about a year away from graduating college so I figured I have the time to try it again. The thing is the last time I was dating I was a freshmen and I had been in a long term thing but it flat-lined a year ago. My life is different now and meeting people has changed too.

How does someone who's a career focused developer find someone in the dating pool post-college? For an FYI I've done mainstream sites like eHarmony with a moderate amount of success but nothing that really lasted beyond 2 meetups. (Meeting people at random locations for the sake of it has never been my thing so bars are sort of a non starter).

We love getting feedback, so I'd appreciate any I get from you guys. :)

Didn't really know how to categorize, bit of a question/discussion/curiosity, so I put it here.🤷

Just today I read an article that stated about the Netherlands, where the police will use an "AI surveillance camera" (yey buzzwords incoming 🙄, but it would actually make sense(?)🤷) to detect and punish drivers, holding a smartphone. Pictures without smartphone shall be deleted. How would this system work without having non-smartphone pictures? It needs to build a classifier, doesn't it? (To be clear, the system only reports those images to an officer for further analysis and actions.)

I mean let's consider that the images are somehow pre-processed, then some convolution(s) for feature extraction, then maybe some more intermediate steps and at the end apply the results on a classifier. How would that classifier work? Would a probability between 0 and 1 suffice? And if so, report those from 0,5 and above? Or would there be better techniques?

Anyone in crypto mining?
Have a small question: why the fuck I am payed half of what I was expecting?!
I know the estimation is not accurate, but half of that or less?!?
(Estimation from the H/s)

Blockchain based on SHA256 is now stuck at a certain block due to high mining difficulty, it appears that a miner, mined few blocks at 15 TH/s then stopped, my question how to resolve this issue and is there any setting to adjust (chainparams.cpp) in case this happened if no block is mined in a certain amount of time.

The Youth

How is the youth?

Pretty good question we don´t really like to communicate to older people well actually most of us have a mental issue, I know it´s kind of sad but when life gives you lemons you use them to make girls cry and that our way of thinking “I´m gonna die anyways lrts do something epic” cuz we aren't afraid to talt to the president of the united states of America like this but we are to scared to order mcdonalts of our self. I mean it´s a aspect that everyone knows we don´t know that person could be a murder of maybe that´s a little to over the top but like we just don´t like it OK.

You may ask what dose she mean with mental health issues?

Well we all know the good old depression its just that we life in a world in that you have to be perfect and when you are´t than you are a disappointment your parents want you to be a doctor or lawyer or something like that because it´s a well payed job but your generation wants to be creative we need our space to crate need things and do something amazing but this world is just a weird place were everyone has to be perfect and follow a ideal. Your appearance dosen´t describes how you are not everyone that has tattoos is a criminal or dose drugs nobody talks about the real problems.

What are the real problems?

Let me tell you we life in a world were nobody talks abou suicide nobody want´s to hear about it let me tell a fact.

Every 40 seconds somebody dies because of suicide.

Suicide is like a terror act when you were close to that person you got completely destroyed if you were far away than you got hurt but not as bad as the persons who were close. But nobody talks about this because it´s not “normal” that makes the persons who need help not reach out because they think its´s not okay.Stop the silence and help :)
But how dose it feel to have depression?

Well you can describe it as this:

it´s as you would lock yourself in a room with just a window but that window dose not have a handle but a curtain that closes every day a little more until there is no light anymore and the first days after that happens you will be scared and lonely and it will hunt you down but depressed people have to life like this every day and it becomes a normal state of mind until they decide they aren´t worth living anymore and they try to kill themselves. It hurts to see all those people die but it is the truth and truth is´t always fun.

Why am I writing this?

Honestly im asking myself that but it just feels right to tell wahts in my mind because a lot of people feel like they are tongue tied and can´t say what they are thinking and feeling and don´t express themselves. And also in my head is a lot wrong but at least I feel like I am doing something while writing this. I am one of the generation Z and I am proud that our generation has all this strength to fight for LGBT+ community and the black life's and I am proud that we understood that all this community's have to be respected because all people are on this earth and we all have to survive somehow and it dose not matter what skin color you have or sexual orientation.

But these are just my thoughts I hope everyone is doing well druing these times.

And to everyone I am proud of you and I love you.

firstly, does anyone know of an online telegram or whatsapp group where i can ask silly stuff regarding web dev and get immediate answers, just like it is here?

secondly i am trying to learn js and there are just too many related terms that are messing with my brain:
"some features are supported ines5/es6/es15/es16/es17 , some are supported in chrome's v8/chakra/spidermonkey/android browser , some features are only supported in "serverside" and blocked in all browsers thanks to browser's vm environment; babel can't read this code, some features are provided only by node js..."
WHAT THE MESS IS THIS?

All i am trying to do is to write code that would make a website visible to everyone. if by specific browser , i want to target, chrome and its subsidaries and android chrome/other android browsers .
for other browsers am willing to make external converters later but don't want to change my code by 1 bit. And from what i know, each browser (at least the browsers am thinking of supporting) has the complete JS compilers already built in

can i or can i not built a complete functional website with those things?

and finally my main question : how to make custom exceptions in vanilla js? i saw this answer on stack overflow:
===================
function InvalidArgumentException(message) {
this.message = message;
// Use V8's native method if available, otherwise fallback
if ("captureStackTrace" in Error)
Error.captureStackTrace(this, InvalidArgumentException);
else
this.stack = (new Error()).stack;
}

InvalidArgumentException.prototype = Object.create(Error.prototype);
InvalidArgumentException.prototype.name = "InvalidArgumentException";
InvalidArgumentException.prototype.constructor = InvalidArgumentException;

Usage:

throw new InvalidArgumentException();
var err = new InvalidArgumentException("Not yet...");

=====================================

where is the error code? what would be the exception details? what is the line number/timestamp of error?why is that function making an error, i thought error/exception is a class in JS?

Doing node dev with a friend that never used JS before

He asks about how to make enums for our generic model to use

Good question I think, I'm not sure

Apparently you just make a fucking object and freeze it, go figure with JS

"Wow. I bet that's super fast /s"

Dammit JS you patchwork ass language, I love you but I see why classic language developers are turned off

Got a question on DBMS Normalization. I tried searching but couldn't clear my doubt. So I have a set of functional dependencies for relation R(C, D, E, F, P, R, S) :

F->D
D->F
E->C
P->RC
E->F
S->EFD
PR->EF

So I have to convert this to 3NF. My doubt is that when finding 2NF do we find all the non-prime attributes that are dependent on a particular partial key i.e. do we take it's closure and create new relations for each partial dependency? If we do that then there are overlapping attributes in the resultant relations in this case I found the relations in 2NF as :
R1(P, S)
R2(P, R, C, E, F)
R3(S, E, F, D, C)

But when I just used the FDs as they are given (no closure) I found :

R1(P, S)
R2(P, R, C)
R3(S, E, F, D)

Which one is correct, please help.

The problem as i see it is summed up in the following: everyone is fucking crazy

asked this guy i see here alot working, 'ever feel left behind in hell' he says 'oh this isn't hell it's (redacted) and we're on (redacted)'s mountain so we're closer to heaven'

so i make a not very novel joke anymore and I say "maybe there's a hellmouth over there, and we'd just have a farther fall" he smiled. it was a funny joke. whenever it was first made.

it was cynical humore expressing my present level of personal misery as I rot with everyone else.

also. remembered being able to convince someone to work for 50/hr doled out each hour as was satisfactory.

wonder if its possible again, person in question doesn't appear to be here today. oh well.

far far more honest than the other fucked up shit they do here and yes this whole rant was made before.

so. not a bot :P

and not making the comment about ownership let someone take this piece of life and let me get booted forward 15 years. fuckers.

So trunk-based is the new approach everyone is using, because it is so cool.
I used gitflow for the last projects with azure devops, set up the pipelines like tipically in 1 week if I had other things to do with the help of the portal clicking through things. PR-s triggered pipelines, everything worked cool.
But then trunk-based got momentum, so I worked with this client where 2 developers worked for !!!3 months!!! to setup trunk-based pipeline. It was not my money, so I did not say a thing. They were using infrastructure as code.
I am all in for automation, but seriously? Then again, another project where a DevOps team took 1 dev-month to setup the pipeline + meetings. And what do you get in the end? So that the same image goes on all environments? Like how many releases do you have for prod in a year. Lets say 24. 24 x 5 minutes of manual work for the release, that is 2 hours. So my question is why would you spend 2 hours of manual work while you can automate it merely in a month? Everyone loves to code, but using the ui on the DevOps portal saves you so much time. I don't get this. Maybe I am getting old :D

Good day. I come to ask a question

Does anyone know a free program for Windows to test RAM throughput? In GB/s

Anybody here knows Backblaze's B2 Cloud Storage?
I am thinking of using it to storage video from a web app that I am developing. The process is:
1 - Send video files (both) to storage w/ cli (Done ✔)
2 - Authorize the asynchronous download and shows it on the HTML5's player (reading the doc ✖).

Question:
Anybody experienced some workflow likes this before? I am trying save some time before break my head after read all CLI doc (only cli, I can't find any workflow of it)

Hi So I need some solid advice from you all wonderful people.
I think i am now ready to look into job side of this world, but have lots of doubts , read my story.
I have been learning android for last 2 years. Most of the time i have been trying to understand how stuff works in android , but i have also gained a few other skills ( python programming, kotlin/flutter basics data analysis basics, testing, some graphic designing, aweful web dev ,etc). But i really want to work with Android. I don't have any specific Salary figure in mind, but i guess my knowledge is better or atleast par with most of the good android developers.

So i want to know how is this fresher/placement thingy work?
1.) GETTING KNOWN? : How can i make some good android based company aware that I am available for hiring? Should i start emailing every android related company that i know of? Should i start listing my profile on recruitment sites like linkedin or internshala? This year it is being said that companies will come for placements. From the status of my college, they are going to give me way to less $ , nd i know am not going to like any of them, but i guess i have to sit for them too.

2.INTERVIEW OR DIRECT PLACEMENTS? A little pre-context: i am currently starting my 4th year in clg. Afaik , 4th year isnt that strict and their can be leniency in terms of attendance. But my college is a place full of political cun*s in the name of directors and HODs and I don't know if they are again going to enforce the old 75% mandatory criteria. Plus if the company is from a different state/country , then my attendance would definitely not suffice.
So mainly i am unsure if somehow a company hires me, i would be able to start immediately. I heard that there are interviews for job recruitment after which the candidate is binded with an agreement to do some months training followed by permanent working after college completion.
This type of agreement is very much suitable for me, since from what my friend tells me, trainings can be lenient and understanding regarding exam preparations nd stuff.

So what do company usually chooses? Binding a fresher on immediate working basis or do they consider graduate completion?

Also, i suck at competitive coding. Do i need to polish myself on that or some company is willing to give me chance on the basis of my other skills 🙈(okay, no kidding , that's a serious question. I need to either work on getting better in competitive or build more apps based on that)

3.) ANDROID OR EVERYTHING? From what i have heard, working as a professional fresher is more like being an allrounder than being a domain specialist. But as i already stated, i really dig android and that's no small framework. I may di other stuff too, but won't interest me nd my output might be less efficient than expected.
So freshers can really be asked to do any stuff? Or can i still be in the area i like being into?

4.) COMPANY OR START-UP? Yeah, this is a general debate starter. Ignoring the business side of the conversation ( job safety vs more salary, experience, etc) the thing that's most important for me is the presence of a team. I want someone to assign me a task, whose vision i could follow, from whom i could learn, and some other people who are supportive and doing the same amount / similar work that am doing . This is so much import8 for me that i can easily ignore other factors for a better team. I once took a call from a startup ceo who hired me, a 2 month old android beginner at that time, as the "lead android developer"
But if am being on a team where i am supposed to do any random stuff that is assigned, then obviously this whole point of "visionary, helpful leader, guiding team, "etc goes moot

Question about linux iptables. I am currently blocking all access and whitelisting only when my users launch my software. When software is launched a socket client is also launched, it connects to socket server, identifies itself with a password and disconnects. If given password by socket client is correct, then socket server whitelists the users IP by executing the following command: " iptables -I INPUT -s userIP -j ACCEPT".

My problem is that now I have lots of duplicates of IP's whitelisted and as far as I've heard I should not go over 25k iptable rules.

So my question is how to check if ip is already whitelisted, in order to avoid duplicate iptable rules for for same IP?

Obvious solution would be to store whitelist somewhere (mysql/txt) and double check before whitelisting ip, but maybe there is an easier way to do this?

So I have a question. Currently stuck with php and it seems declined. If not say declined in the near future. The rise of front end and nodejs, go, ect. It seems my stack degrade s everyday. I do side projects with latest tech. But when job interview asks commercial experiences with latest tech. I have none. Rejected. Is it any solution?

I know it a strange thing to ask but I need help with English grammar ( I am not a English native)

I am doing an assignment on context free grammar program.

What the program need to do it "Produce a grammar tree based on the rule"

For example a sentence "Jame sat.", It will need to produce a grammar tree like this.

S
_____|___
NP VP
| |
N V
| |
holmes sat

The only thing I need to do it give a grammar rule to the program like this

S -> NP VP
NP -> N | Det N
VP -> V | NP

What the above rule said is that the sentence is composed of Noun Phrase and Verb Phrase and Noun Phrase is either is a Noun or a determiner and Noun.

Now here is the meat of the question.

I am having trouble parsing a grammar tree for this sentence "She never said a word until we were at the door here"

I have provided my grammar rule below. I think I forget to add some grammar rule or some of my grammar rule are incorrect. I am not a native English speaker so I am having trouble on it.

The search engine have fail me (I have look up various grammar tree) so I am asking for help on devrant. Grammar nazi are warmly welcome :)

S -> NP VP | S Conj VP | S Conj S

NP -> N | Det NP | N PP | Adj N | Det Adj N | Det N

PP | Det NOM | Det N PP

VP -> V | V NP | V NP PP | V PP | V NP PP Adv

VP -> Adv V NP | VP PP | VP AVP | V PP PP | V
ADJP

PP -> P NP

AVP -> Adv | Adv Adj | Adv AVP

NOM -> Adj Adj N | Adj N | Adj NP

ADJP -> Adj | Adj PP

**I am not sure about these two clause below**
VP -> V | Adv
NP -> Adj Adj N
