This story is 100% true.
I got hired onto a team of construction workers to build a house. We set up a meeting with Management to find out what kind of house they wanted us to build, where’s the floor plan, what it’s going to be used for, who it’s for, etc. Management said that they didn’t know all that, we should just get started. They told us that we were going to use “Agile” which means that we just work on small deliverables and build the thing incrementally.
The developer team lead argued that we at least need to know how big the thing is going to be so that we can get started pouring the foundation, but Management told him they just don’t know. “What we do know,” Management said, “is that the house is going to have a bathroom. Just start there, and we’ll know more when it’s done. You have two weeks.”
So we just bought a port-a-potty, and screwed around on the internet for two weeks. Management was outraged. “You call this a house? This is the worst house ever! It doesn’t even have a tv!”
So we bought a tv and put it in the port-a-potty, attached to an outdoor generator. We were going to buy a a dvd player and get it hooked up to cable, but Management rejected the expense request, saying that they didn’t know if we needed it, and we’d come back to that later.
Management decided that we definitely need storage space, so we bought a boxcar and duct-taped the port-a-potty to it. Then to our horror they set up some desks and put a few miserable business interns in there. It went on like this…
After a few years the boxcar grew into a huge, ramshackle complex. It floods, leaks, it’s frozen in the winter and an oven in the summer. You have to get around in a strange maze of cardboard tubes, ladders and slides. There are two equally horrible separate buildings. We’re still using just the one outdoor generator for all power, so electricity is tightly rationed.
Communication between the buildings was a problem. For one of them, we use a complex series of flag signals. For the other we write notes on paper, crumple the paper up, and toss it over. Both of these methods were suggested as jokes, but Management really liked them for some reason. The buildings mostly talk to each other but they have to talk through us, so most of what we do is pass messages on.
It was suggested that we use paper airplanes instead of crumpled up balls, but the fat, awkward fingers of the Business Majors who inevitably take those jobs couldn’t be trained to make them. I built an awesome automatic paper airplane folder, but once again they couldn’t be trained to use it, so they just went back to crumpling the notes up in balls.
The worst part of all this is that it’s working. Everyone is miserable, but the business is making money. The bright side is that this nightmare complex is done so now we know what kind of building they actually needed in the first place, so we can start work on it. Obviously we can’t tell Management anything about what we’re doing until it’s finished. They noticed the gigantic hole in the ground where the foundation is coming in, but we told them that it’s a cache reset, and they mostly ignore it except when the occasional customer falls in.
I’ll probably be out of here before the new building gets finished. I could get a 50% raise by switching jobs, but Management still doesn’t think I should get a raise because I missed a couple sprints.7 -
fork() can fail: this is important
Ah, fork(). The way processes make more processes. Well, one of them, anyway. It seems I have another story to tell about it.
It can fail. Got that? Are you taking this seriously? You should. fork can fail. Just like malloc, it can fail. Neither of them fail often, but when they do, you can't just ignore it. You have to do something intelligent about it.
People seem to know that fork will return 0 if you're the child and some positive number if you're the parent -- that number is the child's pid. They sock this number away and then use it later.
Guess what happens when you don't test for failure? Yep, that's right, you probably treat "-1" (fork's error result) as a pid.
That's the beginning of the pain. The true pain comes later when it's time to send a signal. Maybe you want to shut down a child process.
Do you kill(pid, signal)? Maybe you do kill(pid, 9).
Do you know what happens when pid is -1? You really should. It's Important. Yes, with a capital I.
...
...
...
Here, I'll paste from the kill(2) man page on my Linux box.
If pid equals -1, then sig is sent to every process for which the calling process has permission to send signals, except for process 1 (init), ...
See that? Killing "pid -1" is equivalent to massacring every other process you are permitted to signal. If you're root, that's probably everything. You live and init lives, but that's it. Everything else is gone gone gone.
Do you have code which manages processes? Have you ever found a machine totally dead except for the text console getty/login (which are respawned by init, naturally) and the process manager? Did you blame the oomkiller in the kernel?
It might not be the guilty party here. Go see if you killed -1.
Unix: just enough potholes and bear traps to keep an entire valley going.

I stare through the blueish black backgrounds and blurry colorful syntax into a somewhat familiar office within a mirrored world. That damned reflective glass layer covering these meaningless pixels is certainly not on my side.
The rushing sound of transactions flowing through cables is silenced today. Some blood cloth in the invoicing system is zeroing out everything after the currency mark.
While sighing I spin a one-and-a-half pirouette on my desk chair — even when desperate, you shouldn't give up on style — I take three steps away from my screen and try to harmonize my thoughts.
So much noise, everywhere... Noise from within?
I have been stuck at the apogee of an inhale for a while now. Locked into some masochistic constriction, self-punishment for the blindness which stings my ego.
Just fucking take a deep breath you asshole...
I freeze in place, and fall backwards.
Patterns on the creamy drywall rapidly vibrate and synchronize on vivid rhythms of respiration and resonating basslines. Deep indigo rainbows ripple through tiny veins, in-between chalky grains, raining as fine magenta dust through the ceiling frames.
My bare feet slide over soft oscillating concrete, fine flows of unsievable sand surrounded by toes, toes surrounded by streaming variables veiled in obscure vile abstractions.
A jadegreen field of vectored compressions resiliently rumbles and bounces through the clearances and corners of the vibrant concrete office cave, whispering in tongues. I try to voice my woes in little blips and bleeps but I seem to be missing an asymmetric key to their shrouded sequenced speech.
Suddenly, a wild turbulence breaks up all signals.
Joanna floats by in her tipsy effervescent cloud of disordered black hair and alcohol perfume, one hand grasping grapes, her other waving at me.
With every finger she moves a thousand tensors propagating paradoxically flawed but perfect pieces of an intricate surreal picture, sketching whole constellations of possible paths throughout the leafs of the giant Ficus next to her desk.
She stops dead in her tracks, and asks somewhat hypocritically: "Are you high?"
I can not discern the meaning of her words, and respond stoically.
"Joanna! Check out those branches!".
"Pun intended?", she giggles.
I'm focused on her grapeless hand, her fingers stretching to reach the lush little tree.
On touch, the plant shivers, grappled in the tight net of the puppet master. She pulls her strings, applying measured weights, all nodes normalize, and Joanna speaks in an oddly soft tone:
"Isn't it beautiful, how so many models emulate nature"
Her cheek buried in foliage she babbles on about unbalanced search trees and machine learning models... but from the tips of her fingers tables and indexes flow into the plant. Users, payments, tariffs, invoices and taxes crawl over the bark, joining at thicker branches, joining at the stem....
Joining. JOINING. A JOIN.
"IF THERE'S NO FUCKING TAX MULTIPLIER IN THIS LEFT JOIN, EVERYTHING COALESCES TO ZERO" I shout at a perplexed Joanna who squeezes grape juice over her desk. I hop on the beat to my keyboard. She looks puzzled, hugs her Ficus tightly, and reaches for the whiskey bottle behind her monitor.
Attracted by my exclamation, Tom from finance swings open the door, while I push my branch.
I look at Joanna still half hiding between the leaves, and I laugh at her: "Branches! Oh, lame, I finally got it!"
Tom's heavy voice interrupts me: "Does this mean... does this mean that the invoicing bug is resolved?".
I smile at Tom with his tailored suit and waxed hair. "The money is flowing once more. All debts are being settled."
He releases his breath in relief, which he seems to have held since that morning as well.
Joanna adds: "Although I think he is forever indebted to my Ficus".
I nod.14 -
Drunk Dev 1: These wifi signals are really take toll of brain tissues and may probably cause brain cancer. 🙁
Drunk Dev 2: Let’s power off our wifi router. We don’t need wifi while drinking. 😏
Drunk Dev 1: Good, but what about other wifi signals in proximity. Your neighbours ?? 🤨
Drunk Dev 2: Oh poor, they wont get into our brains as our brains don’t have password for their wifi thus, we can’t connect to their access point 😎
Drunk Dev 1: 😳6 -
1. Fucking MySQL database clusters.
There's nothing fun about MySQL clusters. Sometimes they start producing deadlock errors for no apparent reason... well, there's probably a reason, but it's never a transparent easy to find reason.
What was even less fun is that those errors took down a Sentry server. When your error log server goes down through ddos from your database messages, it's time to rethink your setup.
2. Wiring up a large factory with $2 arduino clones, each with a $2 esp8266 wifi chip, with various sensors for measuring flow of chemical solutions (I wanted cheap real time monitoring as an early warning system next to periodic sampling).
The scaling issue was getting over 500 streaming wifi signals to work in a 55c moist slightly corrosive atmosphere with concrete and steel everywhere, and getting it all into a single InfluxDB instance for analysis.12 -
Long long ago there was a man who discovered if he scratched certain patterns onto a rock he could use them to remind him about things he would otherwise forgot.
Over time the scratching were refined and this great secret of eternal memory were taught to his children, and they taught it to their children.
Soon mankind had discovered a way to preserve through the ages his thoughts and memories and further discovered that if he wrote down these symbols he could transfer information over distances by simply recording these symbols in a portable medium.
Writing exploded it allowed a genius in one place to communicate the information he had recorded across time and space.
Thousands of years passed, writing continued to be refined and more and more vital. Eventually a humble man by the name of Johannes Gutenberg seeking to make the divine word of God accessible to the people created the printing press allowing the written word to be copied and circulated with great ease expanding vastly the works available to mankind and the number of people who could understand this arcane art of writing.
But mankind never satiated in his desire to know all there is to know demanded more information, demanded it faster, demanded it better. So the greatest minds of 200 years, Marconi, Maxwell, Bohr, Von Nueman, Turing and a host of others working with each other, standing on the shoulders of their brobdinangian predecessors, brought forth a way to send these signals, transfer this writing upon beams of light, by manipulating the very fabric of the cosmos, mankind had reach the ultimate limits of transmission of information. Man has conquered time, and space itself in preserving and transmitting information, we are as the gods!
My point is this, that your insistence upon having a meeting to ask a question, with 10 people that could've been answered with a 2 sentence email, is not only an affront to me for wasting my time, but also serves as an affront to the greatest minds of the 19th and 20th centuries, it is an insult to your ancestors who first sacrificed and labored to master the art of writing, it is in fact offensive to all of humanity up to this point.
In short by requiring a meeting to be held, not only are you ensuring the information is delayed because we all now need to find a time that all of us are available, not only are you now eliminating the ability to have a first hand permanent record of what need to be communicated, you are actively working against progress, you are dragging humanity collectively backwards. You join the esteemed ranks of organizations such as the oppressive Catholic church that sought to silence Galialio and Copernicus, you are among the august crowd that burned witches at Salem, the Soviet secret police that silenced "bourgeoisie" science, you join the side of thousands of years of daft ignorance.
If it were not for you people we would have flying cars, we would have nanobots capable of building things on a whim, we would all be programming in lisp. But because of you and people like you we are trapped in this world, where the greatest minds are trapped in meetings that never end, where mistruth and ignorance run rampant, a world where JavaScript is the de facto language of choice every where because it runs everywhere, and ruins everywhere.
So please remember, next time you want to have a meeting ask yourself first. "Could this be an email?" "Do I enjoy burning witches?" if you do this you might make the world a little bit of a less terrible place to be.6 -
Continued from pervious Rant.
The Drone sends out a signal to the Headquarters. A "Rare Entity Found" alert shows up on the screen. "Quick, load the map", says the General. Map shows the current location of the Drone. "Dispatch the Team", signals the General while his forehead show signs of tension.
Further down the room, a man quickly types on his phone and hides it.
Far from all this, in a quite city where the street lights have faded away. Old buildings which look like they are about to fall and crumble. The sound of wind can be heard for miles as there is silence all around. A light from one of building's room is turned on and quickly turned off. A man, checks his phone in sleep. Awakens and pours a glass of water to drink. Quenching his thirst, he opens his laptop. Laptop's light is the only light illuminating his room. He again gives a second look at his phone. The message is still there.
"It has been found"4 -
---WiFi Vision: X-Ray Vision using ambient WiFi signals now possible---
“X-Ray Vision” using WiFi signals isn’t new, though previous methods required knowledge of specific WiFi transmitter placements and connection to the network in question. These limitations made WiFi vision an unlikely security breach, until now.
Cybersecurity researchers at the University of California and University of Chicago have succeeded in detecting the presence and movement of human targets using only ambient WiFi signals and a smartphone.
The researchers designed and implemented a 2-step attack: the 1st step uses statistical data mining from standard off-the-shelf smartphone WiFi detection to “sniff” out WiFi transmitter placements. The 2nd step involves placement of a WiFi sniffer to continuously monitor WiFi transmissions.
Three proposed defenses to the WiFi vision attack are Geofencing, WiFi rate limiting, and signal obfuscation.
Geofencing, or reducing the spatial range of WiFi devices, is a great defense against the attack. For its advantages, however, geofencing is impractical and unlikely to be adopted by most, as the simplest geofencing tactic would also heavily degrade WiFi connectivity.
WiFi rate limiting is effective against the 2nd step attack, but not against the 1st step attack. This is a simple defense to implement, but because of the ubiquity of IoT devices, it is unlikely to be widely adopted as it would reduce the usability of such devices.
Signal obfuscation adds noise to WiFi signals, effectively neutralizing the attack. This is the most user-friendly of all proposed defenses, with minimal impact to user WiFi devices. The biggest drawback to this tactic is the increased bandwidth of WiFi consumption, though compared to the downsides of the other mentioned defenses, signal obfuscation remains the most likely to be widely adopted and optimized for this kind of attack.

Just a friendly reminder to fellow developers to take care of yourself.
If your system is constantly pumping out cortisol, even when threats are minor, it gets desensitized to the stress signals. We used to react to cortisol with the fight-or-flight response when our lives were in real danger. Nowadays it's produced when you disagree with your coworker or there's a deadline coming up. So your cortisol rises but you neither fight nor run. The result is a stress response that isn't functioning properly. This is when burnout symptoms develop. Same goes for testosterone, dopamine and some other hormones and neurotransmitters. Read up and start proper work hygiene that includes workouts, fresh air activities and manual hobbies.
Your back, wrists and eyes aren't the only things you have to watch out for when coding long hours. Cheers and have a fun weekend!8 -

So I have this 13 year old cousin who's pretty determined to follow my footsteps as a developer someday. He really likes gaming and all internet stuffs. His future plans makes me happy since I may finally have a relative that is a developer. But darn it! He's kinda weird coz he still throws tanrums. One of his major tantrums(which happened again last night) is that he wants the wireless Karaoke machine to be turned off because he thinks that it's slowing down the internet. It was his sister's birthday party and the guests are partying. I've told him many times that the signal for the karaoke is different from that of the router which has nothing to do with the internet slowing down. It must be caused by q device that is updating some apps or whatever. We live in the philippines and our internet provider is quite fast but it has this stupid fair usage policy that caps our bandwidth to a minimum speed if we reach a certain amount of data usage. Since he goes to youtube everyday in 480 and 720p, I explained it to him that it was one of the causes.
Last night, I almost got triggered because I wanted him to believe about the wifi being different to that of the karaoke machine's radio and that it is not connected to the wifi and not using data. I also told him about different kinds of wireless signals which I studied as a Software Engineering student back then and yet he still doesnt believe me. And what almost triggered me is that i saw his steam client updating while watching youtube. I told him that was it. But instead of agreeing, he refused to believe me and just told me that steam is just updating and he's not downloading anything which made me think why he keeps going to youtube, because...he's not downloading. Oh God! Good luck to this kid. 😂5 -
FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.14 -

Hello.
C++ is mysoginist, patriarchal and i propose the 'friend' keyword be removed as it oppresses weak people like me and the developers of lang are fkin racist neo nazis and hope they die in hell for what dey did.
It has just come to my attention that if a class declares another function or class as 'friend' the other func/class can access the private members of the said class. I haven't also coded even a day in c++ but that information is irrelevant as of now.
THIS IS VERY OFFENSIVE TO ME AND SENDS ALL THE WRONG SIGNALS TO SOCIETY. Just because i call you a friend does that mean you can grope me in public? How can women be safe if their private parts can be accessed by any of their friends?
WOMEN ARE OPPRESSED IN WORKPLACES AND I TELL YOU ITS ALL C++'S FAULT. I WILL NOT TOLERATE THIS BIGOTRY YOU FILTHY

Woman should be a commentator at sport events. She woke up at 10 in the morning and has been talking to what seems like the entire fucking population of this goddamn world, it's going to be 10 in the night soon. I feel like I am staying as a leech so I have no say in this goddamn room.
Please someone help me design a fucking signal jammer so I can block out the signals to shut her up!

The hand of IT guy in family
My family sees me as guy who works on IT stuff. The best part is that I will have to help them whenever they encounter problem regarding electronics in daily activities.
Son! The internet is not working
Son! The printer is not working
Son! The TV is not working
Son! My phone didnt get any signals
Son! The microwave is not working
Son! The TV remote is not working
Son! Why is this whatsapp popup always appear whenever I opened it
Son! The dvd player is not working
Son! My phone wont charged
Son! I want to buy online stuff
Son! The email that ur uncle sent me cannot be opened
Son! The email that ur aunt sent me is not there
Son! Can u help me download this travelling app
Son! I opened a website and it told me that I have 163718362 virus!
Son! I forget my password of my facebook account!
Son! Some guy idk on facebook added me as his/her friends, what should i do?
....
Son! The internet is not working (again)
The fact is that, most if these problem, I helped them by just.. restarting the router, reboot the router for 1 min interval, find specific toggler in disfunctional hardware that they accidentally hit during sweeping the floor, take out the power and put it back again, show them how to's in many account/payment mechanism in apps, etc
The very best part that whenever they satisfied, whenever things back to work again, whenever they can reset the password:
"I've tried what you told me, but it just didnt work, but idk when u did it, it works! you are really an IT guy"
And i was like

Why don't people respond to emails? Everyone complains that things could be handled in an email instead of having a meeting. Well maybe you should start replying to my simple fucking questions so I don't have to send meeting notices. You always accept the meeting notices but you NEVER reply to emails! What the fuck people? Now I'm arranging a meeting for 15 minutes just to get a simple is yes or no question answered, are you kidding me here? You're part of the problem! You are THE ENTIRE problem!! You know how much of my time I've wasted getting no answers in IMs and emails?! Should I try smoke signals? It's not even a hard question! Will someone be at the site on the day we need them to be?! How hard is that question to answer!? Evidently im-fucking-possible!5

Update: https://devrant.com/rants/5220410/...
I resigned from my second job.
First job tenure: 7.5 years
Second job tenure: 10 months
This job taught me a lot and paid me decent, but not enough to cope up with the bullshit and sacrifice, WLB, and happiness.
I landed a job at one of my dream companies I always wanted to be and possibly the best company in my city. Also the role is B2C in nature and one of only profitable start-ups from India. The domain is second favourite of mine (Music > Art/Events > Travel).
Second job was in travel domain, world's largest OTA but the timezone fucked my happiness and that is what my first job offered me.
I could easily score better offers with higher pay and benefits but I was optimising for a work life balance and team in same time zone along with some impacting work.
I do have some interesting interviews coming up and I am not sure how will I end up performing.
When I got this first offer, this job hunting season, I initially rejected some silly policies. I regretted the decision and thankfully after having a transparent conversation with the recruiter, I accepted it. Funnily, the resignation from second job isn't making me feel emotional, guilty, or any negative emotion. Which evidently signals that the job was toxic and I had to step out asap.
The purpose it served in my journey was bring my remuneration to market levels and teach me a lot more skills in just short span.
Excited to see how the future unrolls. I'll keep my fellows here posted.
I really want to spend more time here talking and hanging out with you all. Hopefully I shall be back soon. Until then keep safe my lovelies :)5 -

I'll post a rant (will be long) soon-ish on the root of the asinine problem...
TL;DR
Anyone got a better suggestion of killing a WLAN router signal than a Faraday Cage?
-----------------------
As to the point as I can manage atm...
My ISP forces a proprietary router/modem for them to script my static IPv4 block (/28, aka 13 usable). Modifying this equipment in any way or using the vast majority of tactics to modify its behaviour = Federal Felony... with my history, it couldn't be construed as mistake/ignorance of this fact, so I'd likely end up working for some branch of the gov to mitigate the costs of standard prison (on both ends... handicapped af = expensive af to comply with base human rights laws... plus I'd be a dangerous prisoner from what I've been told).
I NEED the ipv6 functionality TOTALLY off... I've written this into every kernel and every container config at kernel level.
The issue is, I don't trust their shit device (which "should" also be set to no ipv6 via gui... non-GUI = fed felony).
This horrid device, they apparently made them for home use initially (to be fair it has decent specs and tolerable RAM), so included WiFi... that comes on by itself.
Disable the WiFi!... except I cant (at least not without 'tampering').
Why? Well acc to the GUI it's not enabled in the first place. Acc to the 'tech support' it's apparently a paid feature (yes, nonsense) that I have not paid for (nor would I), meaning on their end's GUI and DBs I also don't have WiFi ability from that dev.
So... Not trusting the other settings and the dev, being something im not allowed to directly config outside of their GUI that doesn't realise it's putting out a usable signal despite registering DHCP on behalf of that non-existent signal. I NEED to kill those signals.
I realise it likely sounds extreme to make and use a Faraday Cage for a router/modem (secondary modem, it parses the initial modem's output, via script, to allow the static block to be accessed). I really dont know any other way that's legal to restrict it.
Oh, in case unclear, I have tried so many ways to get them to just allow me to use any device (pref. mine, but even their's) that i can simply script myself... it's a no-go.20 -

Dear recruiters, if you prefer telephone calls, why not also learn how to leave a message on a voicebox, display a caller ID, and list your phone number on some legit page on the internet?
Otherwise you'll leave the impression of a desperate outbound call center agent paid not by leads and conversions but just by the quantity of calls made during the day. If I had such a job, I'd also call voiceboxes and busy developers all day and get money for listening to signals tones before hanging up. -
Malwares are nasty applications, that can spy on you, use your computer as an attacker or encrypt your files and hold them on ransom.
The reason that malware exists, is because how the file system works. On Windows, everything can access everything. Of course, there are security measures, like needing administrator permissions to edit/delete a file, but they are exploitable.
If the malware is not using an exploit, nothing is there to stop a user from unknowingly clicking the yes button, when an application requests admin rights.
If we want to stop viruses, in the first place, we need to create a new file-sharing system.
Imagine, that every app has a partition, and only that app can access it.
Currently, when you download a Word document, you would go ahead, start up Word, go into the Downloads folder and open the file.
In the new file-sharing system, you would need to click "Send file to Word" in your browser, and the browser would create a copy of the file in a transfer-partition. Then, it would signal to Word, saying "Hey! Here's a file that I sent to you, copy it to your partition please!". After that, Word just copies the file to its own partition, signals "Ok! I'm done!", and then the browser deletes the file from the shared partition.
A little change in the interface, but a huge change in security.
The permission system would be a better UAC. The best way I can describe it is when you install an app on Android. It shows what permission the app wants, and you could choose to install it, or not to.
Replace "install" with "grant" and that's what I imagined.
Of course, there would be blacklisted permissions, that only kernel-level processes have access to, like accessing all of the partitions, modifying applications, etc.

2nd post progress of this project https://devrant.com/rants/9985730/...
I went to shop to buy missing ir diode and bluetooth for arduino.
Launched arduino today with ir receiver and I managed to reverse engineer protocol.
Turns out it’s just NEC remote codes.
I used this library https://arduino.cc/reference/en/... to easily send and receive ir signals.
Everything took me whole day cause I’m rookie in hardware.
I can now remote control medion md 19500 using arduino.
Next step is to make it riding itself.
I need to measure speed and turn angle with error rates.
I will probably use pen and paper and let vacuum cleaner draw angle for me and after that I will use the most modern, accurate and cheapest angle measurement tool that is protractor - school welcome back
Speed can be more complicated and need another external complicated tool that is tape measure and a clock.
I also bought second robot because I got this stupid idea to allow people to control robots using internet.2 -
Got the job. Not sure I want the job. Or any job in my field. A quarter century feels like too long for any profession. But I don’t have any other marketable skills. Maybe I’ll be a truck driver. Or wash peoples’ car windows when they’re stopped at traffic signals.9

People just can’t show up on time. I respect people’s time and I do not waste a minute of anyone s time. I do not like it. Time is a precious resource and we should all treat it as such. I expect the same from other people too.
There was a meeting supposed to happen a month or so back. Me and another guy. This meeting was basically giving him the resource utilization and some cost related details for the budget our team used up. They wanted a more granular report than the generic ones we submitted.
He scheduled it once and about ten minutes before he cancelled it. Fair enough.
A week later he sent an invite and the next day he cancelled it a few hours before the meeting. Fair enough I’m still not pissed.
A month or so since the first scheduled meeting, he scheduled a meeting and I turn up and he s not there and I wait for about half hour before I leave. Next day I get an email saying he s sorry. Now I’m pissed.
A couple weeks back he schedules a meeting and I turn up and I could see through the glass door and he s talking to someone in the room he s in. He signals to me to wait for five minutes. It takes about 20. Finally I go in and he s relieved so he can finally get the data from me. I tell him I waited for twenty minutes and I have to somewhere and asked him to reschedule the meeting. He asks when and I tell him a time where I know he won’t turn up. About 8 30 in the morning. He says yes.
Next day I show up he s not there and I wait for ten minutes and just he s walking in to the floor I exit the room and run to my place. He comes over and asks and I tell him I waited for sometime and I’m busy now and he mumbles and goes away.
By this time it is already a week or so after the deadline. The bigger boss from finance turns up and asks me why I haven’t given them the data I asked for. I tell him they schedule meetings and don’t turn up on time and my other work is getting affected productivity blah blah and he says okay make the report and give it to me. I tell him no I’m not wasting anymore time on this.
He goes to my boss creates a little ruckus my boss comes over and he goes wtf. I tell him what happened. He says it’s okay give them the report. I’m like I don’t know where I kept it must be somewhere I can’t waste anymore time on this. Guy from finance joins us at this point and angrily says he’ll find it himself and don’t need our help anymore.
The file is in my laptop I use for travel. Just a local copy. Zero fucking backups. And I just deleted it.
Fuck. You.1 -
What would be the best "hot"/upcoming languages for a final year college project?
The project will focus on reverse engineering.
Basic Example: Intercepting signals from products such as a toy helicopters/drones/etc, reverse engineer the signals and try gain control of the device from that.
That's just a very basic function and there will be much more to it, but I'm struggling to decide on a language to pursue hand-in-hand with this project!
I hear Rust, Go, Julia and co being tossed around a lot.
Any suggestions would be helpful!

The day I read The Simulation Argument, by Nick Bostrom, a thought popped into my mind: "if we are made of code, maybe there are ways to hack life as you would hack some random program", I started thinking privilege escalation over the simulation, buffer overflow, picking signals as if I was eavesdropping... it was an epiphany and also fun10

Fucking pimatic.... I'm not fucking able to send just raw 433MHz signals like in pilight. Now I have to use the fucking shell-execute plugin to communicate with pilight to send the correct codes to my RF Sockets.
(Btw the pimatic-pilight plugin is deprecated so I'm not able to use it)
Fuck. But. Hey. It. Works. -
I told you guys that I would update you on my PiBM-5150 project. I figured out the hard way that my USB to DB-25 cable wouldn't cut it. Seems it is for printers and no matter how hard I tried it wouldn't work because of the path of the wires. After researching, it is apparent that the GPIO pins on the pi are configured for serial by default but it requires a little voltage change from TTY to RS-232. Rather than do like one of the videos I saw and solder junk to a bread board, I found a serial (rs-232) shield and 9pin output for the pi. Now, both computers are true rs-232 each. Instead of using a modem between them, I bought a null modem cable (crossover of Tx Rx signals) to interface the two machines directly. I'll update this evening to show it hopefully working.

Last year, we got a new DOCSIS modem from our ISP (Puma6-chipset, nuff said, not allowed to replace it with a proper one).
With this replacement modem came a splitter (to split internet signals from TV signals), keep this in mind for later.
It worked alright for a while, but fast forward to last Januari, our internet started acting up because the modem kept randomly rebooting.
So we had 3 maintenance workers come by already.
The first one replaced the wallplug.
The second one replaced the wallplug, saying that the previous maintenance worker did a shit job.
The third one replaced the splitter.
Now, later that evening, we got an email... stating that the costs would be 50 euro...
Ehm... what?
So I went to contact their customer servers and they said "but the splitter is part of the indoor installation. So if this splitter causes a malfunction, the maintenance worker will charge you for the visit".
So these fucking assholes give me a defective splitter and charge us to have it replaced?
They can suck my big black.
Still going on with the dispute now because that is some top level bullshit.
"What if it wasn't the fault of the splitter? Am I gonna get my money back?"1 -
Some humans are calm and thoughtful, some annoyingly complicated, while others with behaviours too difficult to comprehend.
I got a call from the office (former from 6 months ago) and it's from the G.M herself.
** Phone rings **
Hmm see who's calling...
Me: * Picks up phone and set it on loud speaker, so my partner can also listen *
Me: Hello Ma
G.M: Hey (calls me by my full name)
Me: It's really nice to he...
G.M: Why would you move the YETI server hosted on AWS to Azure! We have been faced with lots of challenges ever since and that has cost the company a lot.
Me: Pardon me Ma, but that...
G.M: That is a very bad and unacceptable behaviour from you and I can have the company sue you for this.
Me: Excuse me Ma, but...
G.M: I have spoken with the director of C.M.D quaters (A sister company) and explained the situation on ground about what you did before leaving without having any prior permission. What nonsense!
** At this point my partner let's call her "CC"... was more confused than me**
CC : **Panicking** Who's that? What did you do? I thought you said you no longer work at that firm, what's going on?
Now I'm confused cus I don't even know who to reply.
Me: **Signals CC to calm the fuck down**
G.M: ** Still talking and spitting out millions of threats to the guy who left the company with evil deeds in mind...**
CC who literally hates suspense and also a half cool and half crackhead kind of person... Tries stealing the phone from me so she could pour out whatever is on her mind to the caller because of how disgusted she felt, mostly for reasons I quite understood but nevertheless i kept the phone far from her reach while we both enjoyed the suiting voice of *a threat giver*
Honestly at this point my closest guess was "Joe, who must have fucked up big time" because Joe is the company's SysAdmin and has a lot of fucked up records (One time Joe tried to convert all system OSes to Linux even with our hydra servers with pre-installed windows running smoothly, his action caused a noticeable server down-time all for the reason of Joe being a Linux freak). He and only he has the power to transfer/switch/off/on servers at will. I really don't know what Joe must have done but sure thing is there is a fuck up somewhere.
Talking about me, I was only a developer enthroned only within his desk and secondly I no longer worked there. Who fucking calls a retired soldier about a lost battle after six freaking months later! Just fucking sink with your ship captain!
But how can I explain all of this to G.M without implicating Joe and also not look like snitch, I thought to myself.
While I was pondering within myself and the call which has long been disconnected, CC broke the silence.
CC: Giddy, Can you honestly explain me why your old company is calling talking about lawyers and suing you? Have you been lying to me about your work?
Me: *Explained the situation to CC*
CC: But why was she that saucy and acting a bitch? You should have spare me a minute with her.
Me: She wouldn't let me speak but we good CC. We good.
The woman that just called is the G.M. of the firm I had formerly worked with and she's also the wife to the M.D of the same firm which was my former direct Boss whom I respect a lot. Having a disjunct with the wife can also affect the relationship with the husband, which I don't want to lose. So we cool!
Maybe I should text her or maybe not... But before then
** Another call comes in **
It's her again.
GM: Hello Giddy (Sounding calm)
Me: (WTF. She called me by my first name and also sounds cool... More confused than a stray dog) ...Yeah Hello
GM: I just called to let you know that my accusation was wrong because I was misinformed. Joe Nosa was in charge on Systems but why didn't you correct me on that during our last conversation?
Me: ... 😲
CC: (Drags the phone) Hello and Good morning whosoever...
G.M: Sorry who am I speaking with?
CC: (Introduced herself) I overheard your last conversation with Giddy, and I demand you appogise to him both in written and in verbal because not only did you accused him falsely, you also almost bridge the trust between us which may have cost the relationship.
Me: ...
** Long awkward silence **
G.M: Hey Giddy, I'm sorry. Just angry about what went down recently.
Me: All good ma'am
CC: ** Hangs up **1 -

Seems quite interesting, can anybody list more such "red flags" and maybe ellaborate a bit and give a few anecdotes?

Know what really grinds my gears?
People who refer to "ajax" as though it's a separate programming language, instead of what it is, which is an old shitty method in an old shitty library. What I do enjoy is people thinking it's dish soap. That will *never* not be funny to me.
Examples:
1. *generic job description*...5 years experience. Desired skills: HTML, Foundation, PHP, Ajax, Fortran, Assembly, Tagalog, smoke signals.
2. Someone in "marketing": "Do you know Ajax?"
3. Jackass in a coffee shop who uses moustache wax: "I'm an ajax programmer. Yeah I've heard of [any recent band], like twenty years ago. They suck."
Go die, and take ajax with you.2 -

Nah, for real, though.: How are y'all doing? It has been a long time. I hope y'all are having a great time (can sense some peoples' incoming negative comments due to corona).
I built my completely new first gaming rig like a few weeks ago after my school laptop stopped showing any signals.
The specifications are the following.:
- Mobo: MSI B450 TOMAHAWK MAX
- CPU: AMD Ryzen 5 3600 (no iGPU)
- dGPU: KFA2 RTX 2070 SUPER OC
- 2nd dGPU: GTX 550 TI (this one gets a new rant/post)
- RAM: 2x G.SKILL Ripjaws V 8 GB 3600 MHz
- PSU: Be quiet 650 W (It was the platinum edition afaik. I originally bought the 600 Watt Gold edition, but somehow they sent me the 650 Watt for no additional charge... which is great for me haha)
- HDD: 2x 4TB NAS HDD in RAID1 configuration (to load all of my games around 2 TB right now. Got the two HDDs for 110 Euro including the SATA Data cables)
- SSD: One Intenso 240 GB SSD and a reused Samsung 256 GB SSD from my old broken Lenovo laptop
- Case: Be quiet Pure Base 500 black with a glass panel on the side
While building my first PC, it was one hell of a challenge. I knew how it all was working in theory, but to put it all together, practically, was a bit of a challenge, but it was a nice challenge. I learned a lot and have a performance gain I could only ever dream of.
I used to play my games first on a Toshiba satellite l750d laptop (around 40 fps in cs:go with the lowest gfx settings) and then on a Lenovo e51-80 laptop (around 30 fps max minecraft with no shaders and texture packs).
Now I play cs:go on Kubuntu with 400 fps at peak with ultra high graphics. It is unbelievable.
I couldn't trust the system when I turned on the fps display the first time I saw it.

So . . . for the first time ever I feel like I'm a part of something I genuinely care about. I'm a Unity3D VR developer, albeit for a small company, which has me in and out of VR constantly most days as I test things. Pretty cool right?
Well here's the thing. For me . . . what I do is trivial in meaning. I love what I do, don't get me wrong, but what's so good about what I do, is that I am a valued team member. My opinion is heard, I am given freedom to innovate, and most importantly I am allowed to create!
So what did I do today? I started building a UI framework for Unity3D, the beginning of which dynamically binds zenject signals to UI elements, like a button's onClick for example. If anyone here has worked with Unity3D you probably can attest to the festering heap of dogs vomit that is Unity UI....2 -
I somehow highly doubt the effectiveness of this treatment... if it did work I'm pretty sure we would all have baby faces with the amount of RF signals we're exposed to in a day. Do you think there is any legitimacy to this claim?

I've been writing on this TCP server the last few days to integrate our software with some services used by the rest of the company.
Noticed the company service keeps making a new connection for every single message, and closes this at client side (without signifying the server).
So I contact the team who wrote these services and ask them what's happening. Team lead of that team doubts that I know what I'm talking about and tells me TCP automagically signals the server on disconnect, and this probably is a .Net only problem.
5 seconds of googlefu: half open tcp connection.
Apparently, the application doesn't care about dropped connections and losing connection states even though every service should be checked for licensing when connecting to the server. With this set-up everyone can just send a message other than the registration and pass through any 'validation' due to the fact there can be no connection state.

Currently trying to make newer C++11 code run on a gcc 4.8 compiler. Also making Qt 5 code run on Qt 4.8. Enabling experimental flags on gcc like std=c++1y and turning on flags to turn off complaints about pre c++11 code. Have my cake and eat it too. My favorite so far it to create a proxy object so I can connect lambdas to Qt signals. This is supported in Qt 5, but not Qt 4. I feel like I am traveling back in time to when stuff was shittier standards wise.5

I was late with getting into programming and only started considering it after completing an education in animation before (unwillingly) working jobs outside of that field for a few years.
I had to really dig to try and figure out what I'd enjoy doing, and it's when I asked myself what I enjoyed about things in the past like railroad tycoon that I got on the track (eh?) of putting stuff together and making it work.
I remember seeing my friend play and I was screaming internally at his "who cares it works" solutions. When we later played ottd I would try to set up my stuff so that it was readable and because I realized how annoying it is when I can't figure out what my friend's tracks are supposed to do without asking him.
I was basically a developer all along. It's just that my only programming language was railroad tracks and signals. -
To the physicists among us:
I'm in the process of planning a very lightweight mini drone that flies with the help of radio signals that's surrounding it.
I'm targeting 100 MHz.
I calculated the amount of energy (Joules) of it and just when I did change the formula from E=h*f to Power=E/time I realized that time is basically going to be infinite and now I am stuck finding a solution to this.
I can't just use a potential infinite amount of time in this equation and need a workaround.
Any help is appreciated.22 -
Hey!
I am trying to learn creating games for android (+- 0 android expirience).
I figured I could use GoDot for it's awesome pricing (free, no strings attached).
I've done few minor things, but, to be perfectly honest, I'm fed up of GDscript. I just internally hate it more every single time I touch it, so recently I stopped attempts to learn doing games for droid/iOS.
I'm looking for free alternative to godot, preferably no strings attached, but wahtever... Here is what I need:
- I prefer code, but doing stuff in GUI is fine, but stuff like making level etc, preferably in UI
- C++ derrived syntax (ex. c# etc. c++ is fine too), no BS like some wacky workaround to do basic shit like 2d array....
- easy android/iOS export (like in godot, one day I was attempting to hello world in android and compiling for first time... was quite an advanture)
- objects
- some easy way for restfull apis
Good to have:
- ability to test project without android VM
- observer pattern (signals/slots)
I don't care what structure it's made, for me milion of scenes on one screen was extremly coutner-intuitive but meh, whatever. As long as it's possible to learn, it is fine.
Can devranters help, please?
Thanks,
peace.16 -
For years now I've been "dreaming in code" but in the stupid way, which is only appropiate.
I try to explain it to myself and *I* can't understand it.
One, by some oniric enchantment, is capable of communicating signals through use of some symbolic language; and any time one speaks, they are affecting all that follows.
So a sequence of these, of any size, corresponds to some kind of program, and the self is some sort of collection of mutable structures being affected by them. And new symbols arise from within the self, corresponding to sequences of previously spoken symbols.
This process in itself can be satisfying, for the mere challenge of engaging with it's bottomless complexity, but it also suffers from a complete lack of purpose.
What does it mean? It's all undefined, yet doing something, so it must *mean* something. But what is it doing? One simply cannot grasp it!
I go to bed at night and traverse my tree, I recognize it, I've been working on it for years. Time is different there, you can just keep infinitely building shit, it never ends. Then I wake up and everything makes sense, for a little while.
But what I see isn't quantifiable; I can't turn it into a representation that works outside of a dream. Does it give me some vague ideas for the "actual" code I'm working on, yes of course. Yet it's all so... elusive, I can never put it into words. How exactly I could think of this? Well, it's in my tree, I know it because I wrote it as I slept. But how?
Fucking brains, maan.1 -
