https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.
For updates refer the kernel tree: https://git.kernel.org/…/ke…/...

@Devintrix , congrats and happy lifes with your wife. this joke is for you :)
Dear Tech Support:
Last year I upgraded from Girlfriend 7.0 to Wife 1.0 and noticed that the new program began running unexpected child processing that took up a lot of space and valuable resources.
In addition, Wife 1.0 installs itself into all other programs and launches during system initialization, where it monitors all other system activity. Applications such as PokerNight 10.3, Drunken Boys Night 2.5 and Monday Night football 5.0 no longer run, crashing the system whenever selected.
I cannot seem to keep Wife 1.0 in the background while attempting to run some of my other favorite applications. I am thinking about going back to Girlfriend 7.0, but un-install does not work on this program.
Can you help me please?
Thanks,
Joe
——————————————————–
Dear Joe:
This is a very common problem men complain about but is mostly due to a primary misconception. Many people upgrade from Girlfriend 7.0 to Wife 1.0 with the idea that Wife 1.0 is merely a “UTILITIES & ENTERTAINMENT” program. Wife 1.0 is an OPERATING SYSTEM and designed by its creator to run everything.
It is unlikely you would be able to purge Wife 1.0 and still convert back to Girlfriend 7.0. Hidden operating files within your system would cause Girlfriend 7.0 to emulate Wife 1.0 so nothing is gained.
It is impossible to un-install, delete, or purge the program files from the system once installed. You cannot go back to Girlfriend 7.0 because Wife 1.0 is not designed to do this. Some have tried to install Girlfriend 8.0 or Wife 2.0 but end up with more problems than the original system.
I recommend you keep Wife 1.0 and just deal with the situation. Having Wife 1.0 installed myself, I might also suggest you read the entire section regarding General Partnership Faults (GPFs). You must assume all responsibility for faults and problems that might occur, regardless of their cause. The best course of action will be to enter the command C:\APOLOGIZE. The system will run smoothly as long as you take the blame for all the GPFs.
Wife 1.0 is a great program, but very high maintenance. Consider buying additional software to improve the performance of Wife 1.0. I recommend Flowers 2.1, Jewelry 2.2, and Chocolates 5.0.
Do not, under any circumstances, install Secretary With Short Skirt 3.3. This is not a supported application for Wife 1.0 and is likely to cause irreversible damage to the operating system.
Best of luck,

--- GitHub 24-hour outage post mortem ---
As many of you will remember; Github fell over earlier this month and cracked its head on the counter top on the way down. For more or less a full 24 hours the repo-wrangling behemoth had inconsistent data being presented to users, slow response times and failing requests during common user actions such as reporting issues and questioning your career choice in code reviews.
It's been revealed in a post-mortem of the incident (link at the end of the article) that DB replication was the root cause of the chaos after a failing 100G network link was being replaced during routine maintenance. I don't pretend to be a rockstar-ninja-wizard DBA but after speaking with colleagues who went a shade whiter when the term "replication" was used - It's hard to predict where a design decision will bite back and leave you untanging the web of lies and misinformation reported by the databases for weeks if not months after everything's gone a tad sideways.
When the link was yanked out of the east coast DC undergoing maintenance - Github's "Orchestrator" software did exactly what it was meant to do; It hit the "ohshi" button and failed over to another DC that wasn't reporting any issues. The hitch in the master plan was that when connectivity came back up at the east coast DC, Orchestrator was unable to (un)fail-over back to the east coast DC due to each cluster containing data the other didn't have.
At this point it's reasonable to assume that pants were turning funny colours - Monitoring systems across the board started squealing, firing off messages to engineers demanding they rouse from the land of nod and snap back to reality, that was a bit more "on-fire" than usual. A quick call to Orchestrator's API returned a result set that only contained database servers from the west coast - none of the east coast servers had responded.
Come 11pm UTC (about 10 minutes after the initial pant re-colouring) engineers realised they were well and truly backed into a corner, the site was flipped into "Yellow" status and internal mechanisms for deployments were locked out. 5 minutes later an Incident Co-ordinator was dragged from their lair by the status change and almost immediately flipped the site into "Red" status, a move i can only hope was accompanied by all the lights going red and klaxons sounding.
Even more engineers were roused from their slumber to help with the recovery effort, By this point hair was turning grey in real time - The fail-over DB cluster had been processing user data for nearly 40 minutes, every second that passed made the inevitable untangling process exponentially more difficult. Not long after this Github made the call to pause webhooks and Github Pages builds in an attempt to prevent further data loss, causing disruption to those of us using Github as a way of kicking off our deployment processes (myself included, I had to SSH in and run a git pull myself like some kind of savage).
Glossing over several more "And then things were still broken" sections of the post mortem; Clever engineers with their heads screwed on the right way successfully executed what i can only imagine was a large, complex and risky plan to untangle the mess and restore functionality. Github was picked up off the kitchen floor and promptly placed in a comfy chair with a sweet tea to recover. The enormous backlog of webhooks and Pages builds was caught up with and everything was more or less back to normal.
It goes to show that even the best laid plan rarely survives first contact with the enemy, In this case a failing 100G network link somewhere inside an east coast data center.

Worked with a European consulting company to integrate some shared business data (aka. calling a service).
VP of IT called an emergency meeting (IT managers, network admins) deeply concerned about the performance of the international web site since adding our services.
VP: “The partner’s site is much slower than ours. Only common piece that could cause that is your service.”
Me: “Um, their site is vastly different than ours. I don’t think we can compare their performance to ours.”
VP: “Performance is #1! I need your service fixed ASAP!”
Me: “OK, but what exactly is slow? How did you measure their site? The servers are in Germany”
VP: “I measured performance from my house last night.”
Me: “Did you use an application?”
VP: “<laughs> oh no, I was at home. When I opened the page, I counted one Mississippi, two Mississippi, three Mississippi, then the page displayed.”
Me: “Wow…um…OK…uh…how long does our page take to load?”
VP: “Two Mississippi’s”
Me: “Um…wow…OK…wow…uh, no, we don’t measure performance like that, but I’ll work with our partners and develop a performance benchmark to determine if the shared service is behaving differently.”
VP: “Whatever it is, the service is slow. Bill, what do you think is slowing down the service?”
NetworkAdmin-Bill: “The Atlantic Ocean?”
VP got up and left the meeting.2 -

Dear Troubled User:
This is a very common problem. Many people upgrade from Girlfriend 7.0 to Wife 1.0, thinking that it is just a Utilities and Entertainment program. Wife 1.0 is an OPERATING SYSTEM and is designed by its Creator to run EVERYTHING!!! It is also impossible to delete Wife 1.0 and to return to Girlfriend 7.0. It is impossible to uninstall, or purge the program files from the system once installed. You cannot go back to Girlfriend 7.0 because Wife 1.0 is designed not to allow this. Look in your Wife 1.0 manual under Warnings-Alimony-Child Support. I recommend that you keep Wife 1.0 installed and work on improving the configuration. I suggest installing the background application YesDear 99.0 to alleviate software augmentation.
The best course of action is to enter the command C:\APOLOGIZE because ultimately you will have to do this before the system will return to normal anyway.
Wife 1.0 is a great program, but it tends to be very high maintenance. Wife 1.0 comes with several support programs, such as CleanAndSweep 3.0, CookIt 1.5 and DoBills 4.2. However, be very careful how you use these programs. Improper use will cause the system to launch the program NagNag 9.5. Once this happens, the only way to improve the performance of Wife 1.0 is to purchase additional software. I recommend Flowers 2.1 and Diamonds 5.0, but beware because sometimes these applications can be expensive.
WARNING!!! DO NOT, under any circumstances, install SecretaryWithShortSkirt 3.3. This application is not supported by Wife 1.0 and will cause irreversible damage to the operating system.
WARNING!!! Attempting to install NewGirlFriend 8.8 along with Wife 1.0 will crash the system.

The only serious, as in customer affecting, bug I never git fixed was an indexing bug that caused an exception requiring manual intervention by one of us.
Despite going at it for many years I never found the root cause before I left the company.
The reason it was so difficult was that it only occurred every second month or less and with different customers.
It was also not triggering directly when the error occurred but a while later once the error had caused accumulated errors until one value got negative.
Also, it was a combination SQL, backend code and frontend js and the time from initial error until an invalid value could be hours, days or even weeks.
And we never ever managed to replicate it our self and found no common pattern between occasions.
We think it was some kind of race condition when updating the db that caused duplicate values or a hole in the index series (db transaction or db index was not an option for various reason that would require a redesign of the central tables and most if the central code).
This then grew into multiple error on consecutive updates until one f them resulted in a negative number that then caused a regex in js to fail.2 -
Cracking old recovery CDs for the 9x/2000/XP era shines some light into how companies operated and when concepts came to be in that time:
Packard Bell: An EXE checks that you're running on a Packard Bell machine and reboots if it's not. How do we bypass it? Easy: just fucking delete it. The files to reinstall Windows from scratch come from...
...
C:?
Yup. Turns out Packard Bell was doing the recovery partition thing all the way back to the 9x era, maybe even further. Files aren't even on the restore disc so if your partition table got fucked (pretty common because malware and disk corruption) you were totally fucked and needed to repurchase Windows. (My dad, at the time, only charged at-cost OEM prices for a replacement retail copy. He knew it was dumb so he never sold PB machines.)
Compaq:
Computer check? Nope, remove one line from a BATCH file and it's gone.
Six archives, named "WINA.ZIP" through "WINF.ZIP" (plus one or two extras for OEM software) hold Windows. Problematic? Well... only because they never put the password anywhere so the installer can't install them. (Some interesting on-disc technician-only utils, though!)
Dell:
If not a Dell machine, lock up. Cause? CONFIG.SYS driver masquerading as OAK (the common CD driver) doing the check, then chainloading the real OAK driver. Simple fix: replace the fake driver with the real one.
Issues?
Would I mention this one if there weren't?
Disc is mounted on N:. Subdirectories work, but doing anything in them (a DIR, trying to execute something, trying to view shit in EDIT.COM) kicked you back to the disc root.
Installer couldn't find machine manifest in the MAP folder (it wanted your PC's serial before it'd let you install, to make sure you have the correct recovery disc) so it asked for 12-digit alphanumeric serial. The defined serials in the manifest were something like "02884902-01" or similar (8-2, all numbers) and it couldn't read the file so it couldn't show the right format, nor check for the right type.
Bypassing that issue, trying to do the ACTUAL install process caused nothing to happen... as all BATCHes for install think the CD should be on X:.
Welp.
well that was fun. Now to test on-real-PC behavior, as VBOX and VMWare both don't like the special hardware shit it tries to use. (Why does a textmode GUI need GPU acceleration, COMPAQ?????)4 -
I miss old times rants...So i guess, here it goes mine:
Tomorrow is the day of the first demo to our client of a "forward-looking project" which is totally fucked up, because our "Technical Quality Assurance" - basically a developer from the '90-s, who gained the position by "he is a good guy from my last company where we worked together on sum old legacy project...".
He fucked up our marvellous, loose coupling, publish/subscribe microservice architecture, which was meant to replace an old, un-maintainable enormous monolitch app. Basically we have to replace some old-ass db stored functions.
Everyone was on our side, even the sysadmins were on our side, and he just walked in the conversation, and said: No, i don't like it, 'cause it's not clear how it would even work... Make it an RPC without loose coupling with the good-old common lib pattern, which made it now (it's the 4th 2 week/sprint, and it is a dependency hell). I could go on day and night about his "awesome ideas", and all the lovely e-mails and pull request comments... But back to business
So tomorrow is the demo. The client side project manager accidentally invited EVERYONE to this, even fucking CIO, legal department, all the designers... so yeah... pretty nice couple of swallowed company...
Today was a day, when my lead colleague just simply stayed home, to be more productive, our companys project manager had to work on other prjects, and can't help, and all the 3 other prject members were thinking it is important to interrupt me frequently...
I have to install our projects which is not even had a heart beat... not even on developer machines. Ok it is not a reeeeaaally big thing, but it is 6 MS from which 2 not even building because of tight coupling fucktard bitch..., But ok, i mean, i do my best, and make it work for the first time ever... I worked like 10 ours, just on the first fucking app to build, and deploy, run on the server, connect to db and rabbit mq... 10 FUCKING HOURS!!! (sorry, i mean) and it all was about 1, i mean ONE FUCKING LINE!
Let me explain: spring boot amqp with SSL was never tested before this time. I searched everything i could tought about, what could cause "Connection reset"... Yeah... not so helpful error message... I even have to "hack" into the demo server to test the keystore-truststore at localhost... and all the fucking configs, user names, urls, everything was correct... But one fucking line was missing...
EXCEPT ONE FUCKING LINE:
spring.rabbitmq.ssl.enabled=false # Whether to enable SSL support.
This little bitch took me 6 hours to figure out...so please guys, learn from my fault and check the spring boot appendix for default application properties, if everything is correct, but it is not working...
And of course, if you want SSL then ENABLE it...
spring.rabbitmq.ssl.enabled=true
BTW i really miss those old rants from angry devs, and i hope someone will smile on my fucking torture5 -
Having some thoughts as I sit here, trapped in the house by equal parts coronavirus and a layer of smoke drowning out the sun. The smoke is a bit of an annual thing; every year, some irresponsible jerk will go out and put their convenience and enjoyment over everyone else's quality of life.
It's a bit different this year since coronavirus has given people cabin fever. Those same people who lose their minds after weeks of isolation and suffering the indignity of wearing a mask headed out into the wilderness for recreation in record numbers.
The result is record wildfires.
Where I'm at, it's mostly coming from the eastern part of our state. The area is typified by being on the mountain range's dry side, more rural, less densely populated. Towns have burned, people lost their homes, millions of acres of land will likely burn before it's over. It happens every year; people pack up, head out into the wilderness, and cause devastation due to a simple lack of common sense or regard for the consequences of their actions.
On the west side, we see the fallout in the form of days without sunlight and abysmal air quality. We also see it in cost; we will unquestionably and without hesitation contribute to eastern recovery efforts. The western half of the state will cover almost all of the damage in both taxes and recovery aid. Our local ethos demands it.
The mountains form a kind of natural barrier, both cultural and environmental. The fact that few people cross the mountains by choice is symbolic of that divide. Those who enjoy greenery and lakes and thriving vibrant nature prefer the west, as we have them in abundance. People who have a strong appreciation for distance between themselves and other humans prefer the east, as it affords them cheaper land and few urban environments.
Here's to hoping people learn from this in 2021.17 -
If you think learning a language / working with a language you don't like is offensive to you and your morals .. Then don't do it.
Money is important to you ? Then you're just prostituting yourself to some higher authority. So DONT COMPLAIN!
You have the right to hate stuff while being paid for it. Understandable.
But don't shit on the shit you think is shit just cause you put yourself in the situation of not having an option !!
You're a worthless. Money hungry whore.
Yes, you hate Java/ x language but have to work on it ?
You're either a whore or have serious problems with standing up for yourself, but on the internet you become this amazing troll saying the language has problems.
Half the people who hate languages hate them cause it's common to hate them. Like being racist in the early American ages cause it was "normal".
Brain deficient motherfucking whores. Manipulated cocksuckers.
Sidenote : if you've honestly gotten shit on by a new version of the language you were using .It's understandable and I'm on your side. Using it without thorough research on the other hand is your mistake. Languages aren't ideal. Just Like most women don't like your dick cause, well it doesn't fit their use case. Deal with it not, troll about it.
I'm not like you. I experiment with whatever I like before using it. I work on my own stuff. I suck my own fucking dick and I get paid.
If you honestly disagree with me, put a couple points down on the language you hate and why you hate it ( considering the fact that you have actually used it and are not just trying to disagree with me )21 -
It’s still to easy.
I hope one day software will get so complicated no one will be able to fix it.
Somewhere in future :
- government established law that new AI system is only one that can accept new law
- every financial operation is monitored by government supervision AI
- we developed robots that are taking care of us
- everyone is happy cause work for money, shelter and food is now optional
- education is fully digital and managed by AI
- whole knowledge is based on asking questions, we don’t need to write and read anymore
- we use one common language and our knowledge specialization increased
A little more time passed by in this utopia.
- after power loss most of data got corrupted
- last man who knew how to restore backup died last night ( R.I.P. admin we will not forget you )
- people trying to save knowledge base to rebuild part of this civilization but no one knows how to make a paper because it haven’t been used for ages
- we decided to put what is left from knowledge on stone but we forgot how to write since everything is audio or video and most of time we were spending in VR
- someone decided that we draw some pictures
- all of use are now drawing animal heads like we remember ourselves from VR, let people know our tech is good
- some people love cats so they try to make cats from stones
- volcano eruptions destroyed most of stones that we made
Starving waiting for another respawn of my DNA sequence. I hope we manage to survive this time.

It took me 5!!!! fucking hours to do it but I did.
I got linux to work with my RTX 2070 oh my god
Most of that time was spent figuring out what exactly was wrong because the problem is hella common but the cause doesn’t seem to be so i was sent off in the completely wrong direction a bunch of times
Apparently Nouveau doesn’t support my GPU yet and installing the binary driver from nvidia seemed impossible but i pulled it off thanks to some random stranger on askubuntu.com
Unfortunately i got it working on elementary os instead of ubuntu so now i have to go install ubuntu 🤷♂️13 -
(Dev)Life in the past 12 hours
Oh boy have the last 12 hours been a roller coaster ride for me. Noob me decided to "compile" AoSP for my device to get a taste of how custom ROMs are built from source. Overall it was fun but the errors were a very good excercise for googling, SO. Couple stuff I learnt ( possibly useful for anyone who comes here )
* The shebang line ( #!/usr/bin/env python ) on my system translated to Python 3.7 environment instead of the expected Python 2.7. Best solution I think to avoid confusion is to create a python 2.7 environment and source it.
* Get your trees right. A jar file called WfdCommon.jar ( apparently known as wifi-display common ) was the cause of several hours of hunting the fault. My vendor tree somehow didn't have this file so dex2oat was borking out like mad. I'm still amazed how I figured this one out almost by myself. ( Basically I had to check every file included in the boot class path, and find the odd one )
* I wasted a lot of time in finding the right files to change version numbers and all. Maybe I didn't search XDA properly for a guide ?
Overall it was a fun experience. Also if anyone's experienced in this area could you share resources to learn more about custom ROM development? Specifically on the tweaking part where you mix features from different ROMs to make a great ROM ( like AoSP extended or Pixel Experience ). All I could find were on the zips and not on sources.

I want to explain to people like ostream (aka aviophille) why JS is a crap language. Because they apparently don't know (lol).
First I want to say that JS is fine for small things like gluing some parts togeter. Like, you know, the exact thing it was intended for when it was invented: scripting.
So why is it bad as a programming language for whole apps or projects?
No type checks (dynamic typing). This is typical for scripting languages and not neccesarily bad for such a language but it's certainly bad for a programming language.
"truthy" everything. It's bad for readability and it's dangerous because you can accidentaly make unwanted behavior.
The existence of == and ===. The rule for many real life JS projects is to always use === to be more safe.
In general: The correct thing should be the default thing. JS violates that.
Automatic semicolon insertion can cause funny surprises.
If semicolons aren't truly optional, then they should not be allowed to be omitted.
No enums. Do I need to say more?
No generics (of course, lol).
Fucked up implicit type conversions that violate the principle of least surprise (you know those from all the memes).
No integer data types (only floating point). BigInt obviously doesn't count.
No value types and no real concept for immutability. "Const" doesn't count because it only makes the reference immutale (see lack of value types). "Freeze" doesn't count since it's a runtime enforcement and therefore pretty useless.
No algebraic types. That one can be forgiven though, because it's only common in the most modern languages.
The need for null AND undefined.
No concept of non-nullability (values that can not be null).
JS embraces the "fail silently" approach, which means that many bugs remain unnoticed and will be a PITA to find and debug.
Some of the problems can and have been adressed with TypeScript, but most of them are unfixable because it would break backward compatibility.
So JS is truly rotten at the core and can not be fixed in principle.
That doesn't mean that I also hate JS devs. I pity your poor souls for having to deal with this abomination of a language.
It's likely that I fogot to mention many other problems with JS, so feel free to extend the list in the comments :)

Hey everybody been a while but I have a rant. Swift fucking swift and IOS dev. Okay so been learning swift for some frontend casual work, no worries they are lending me a mac to work in.
Now comes the rant part IOS is fine to work in I dont have any qualms about platform but.. FOR THE LOVE OF COMMON FUCKING SENSE GET SOME FUCKING CONSISTENCY.
You have made swift statically typed language to supposedly make developing more consistant and better fine no worries i dont like static typed languages cause they are unnecessary but fine. then you go NAH FUCK IT EVERYTHING IN A MODULE IS IN GLOBAL SCOPE, FUCK IMPORT STATEMENTS, FUCK MAINTAINABILITY AND FUCK YOU FOR ASKING.6 -
!dev, just a couple little things that happened to me recently.
First off, I just (like 20 minutes ago) replaced the save battery in my Pokemon Silver, so that's fun. Now I want to start modding my GBC (new shell, glass screen, all the fun stuff)
My friend is talking to me again, as of yesterday. The whole situation is still kinda touchy so I'm gonna be careful about talking to her for now, but after some time it should be all good.
I recently took up vaping (I know, it's bad and I shouldn't do it, but I'm an adult and that's my fucking decision).
Then yesterday, I gave a friend a ride home from school. He didn't have his house key so he was locked out and had to wait for his dad to get home. The neighborhood I live in, you don't really leave someone sitting outside for too long, cause shit might happen to them (drug deals are a regular thing across the street from my house, gunshots aren't too common, but still), so I stayed with him.
I'd never met his dad, and I didn't want his first impression to be me letting out a huge vape cloud, so if I was going to take a hit, I would check to make sure nobody was around. At one point, I checked, then took a huge hit. Then I heard my friend say "oh there's my dad". Cue me practically gluing my mouth shut, not breathing at all as I waved bye, turned my car on, pulled out of the driveway, and drove down the street some.
When I let the cloud out, it was a HUGE fucking cloud too. Much bigger than the ones I've normally had. Definitely would have been a bad introduction, especially considering that friend's family is not very fond of that type of stuff (smoking/vaping, drinking, etc) from what I know. -
That's it, where do I send the bill, to Microsoft? Orange highlight in image is my own. As in ownly way to see that something wasn't right. Oh but - Wait, I am on Linux, so I guess I will assume that I need to be on internet explorer to use anything on microsoft.com - is that on the site somewhere maybe? Cause it looks like hell when rendered from Chrome on Ubuntu. Yes I use Ubuntu while developing, eat it haters. FUCK.
This is ridiculous - I actually WANT to use Bing Web Search API. I actually TRIED giving up my email address and phone number to MS. If you fail the I'm not a robot, or if you pass it, who knows, it disappears and says something about being human. I'm human. Give me free API Key. Or shit, I'll pay. Client wants to use Bing so I am using BING GODDAMN YOU.
Why am I so mad? BECAUSE THIS. Oauth through github, great alternative since apparently I am not human according to microsoft. Common theme w them, amiright?
So yeah. Let them see all my githubs. Whatever. Just GO so I can RELAX. Rate limit fuck shit workaround dumb client requirements google can eat me. Whats this, I need to show my email publicly? Verification? Sure just go. But really MS, this looks terrible. If I boot up IE will it look any better? I doubt it but who knows I am not looking at MS CSS. I am going into my github, making it public. Then trying again. Then waiting. Then verifying my email is shown. Great it is hello everyone. COME ON MS. Send me an email. Do something.
I am trying to be patient, but after a few minutes, I revoke access. Must have been a glitch. Go through it again, with public email. Same ugly almost invisible message. Approaching a billable hour in which I made 0 progress. So, lets just see, NO EMAIL from MS, Yes it appears in my GitHub, but I have no way to log into MS. Email doesnt work. OAuth isn't picking it up I guess, I don't even care to think this through.
The whole point is, the error message was hard to discover, seems to be inaccurate, and I can't believe the IRONY or the STUPIDITY (me, me stupid. Me stupid thinking I could get working doing same dumb thing over and over like caveman and rock).
Longer rant made shorter, I cant come up with a single fucking way to get a free BING API Key. So forget it MS. Maybe you'll email me tomorrow. Maybe Github was pretending to be Gitlab for a few minutes.
Maybe I will send this image to my client and tell him "If we use Bing, get used to seeing hard to read error messages like this one". I mean that's why this is so frustrating anyhow - I thought the Google CSE worked FINE for us :/

I am in a situation where I am tired to give suggestions or implement any improvements to the company's app. I am in a situation where I will just do as told, nothing more, nothing less.
Regardless of how many suggestions or improvements I had made, the boss is constantly sceptically asking for "BLACK AND WHITE " proof. Sometimes, something does not require proof but cause and effect. As the application constantly prompts a DataType issue, which is a common bug in this app! I declare datatype the issue went away.
I wonder how this application can go further when they declare every variable as `var`, not using `const` for constant value, and redundant methods everywhere, most methods are not specific (in dart when you do not specify the method, the method become `dynamic`), a long list of nested if-else for something can be easily solved with switch case, etc.
So, today, right now, I will revert every improvement, and keep the original structure. If anything goes wrong, I know why it happens (deep down I will say "I told you so"). I am here to work for food, not to reinvent the wheel.
I'm so exhausted to the point where I will just go along and tell my co-worker "as you wish"
No more me suggesting.
No more me giving ideas.
No more me pointing the mistakes .
I will let them find out themselves is much better than I say it, just to prevent getting unnecessary hatred from them.
The best punishment to give somebody is to never mention their mistake let their ego do the job of consuming them into ignorance and asleep, and never wake them up. Let them commit the same mistakes repetitively until them realised there's no way to revert.5 -
In highschool we went through something like a malware/phishing prevention course.
It was pretty cool tbh, we spend the whole hour in a virtual environment where you'd see common malware and phishing attempts, but the really fun you could also "hack" other students.
Hacking them means you could cause some things to happen on their "PC". One of those was showing in a captcha on their screen and they had to type a the string of your choosing, before they could access the rest of the "virtual computer" again.
You can probably guess where this is going.
I was the first who had the idea to mix big i and small L and tested it on our teacher, who was also part of this environment and screenshared to the projector.
Thanks to sitting next projection I could see the pixels and I can confirm: same character, Pixel perfect!
I will forever cherish the memory of my the teacher begging me to undo the "hack" and the chaos that followed amongst my peers 😈
Also one of the excersizes was stupid. Click on a phishing mail and enter your credentials in the form. I asked the teacher WTF kind of credentials they even want me to enter to microsooft.cum and they just said "the credentials obviously" so I think they got their karma🖕 -
A few days ago I decided to install Windows 7 on a VM (bad idea as it turned out). All fine and dandy and I ran Windows Update a few times to get it at least as up-to-date as it'll get.
I noticed that out of the 4GB RAM I had allocated, an svchost process responsible for the updates was gobbling up all the available memory, just leaving 82MB for everything else. The process itself was as you might imagine consuming over 3GB RAM just for itself. That's how an OS should work right after installation, I'm sure you'll agree.
So I complained about it. Haven't used Windows anywhere for a while so I wasn't used anymore to this level of efficiency. Disk activity went through the roof, though to be fair the underlying disk wasn't an SSD (qcow2 on ZFS on a spinning drive). RAM consumption is something I already covered. CPU temperature shot up to 95C.
So as any idiot would do, I disabled the service related to that process (the svchost process for wuauserv) and the problem went away. But I complained of course, saying that such amazing system utilization metrics wasn't something I expected. I mean for 4GB allocated, having as much as 82MB usable to get stuff done with! 95C on the CPU, on a lot of chips that's the junction temperature! Absolutely beautiful.
When I complained I heard that I had to replace the thermal grease. I do that twice a year. I wrote a custom fan driver for my system that works absolutely great. It was obviously shit. I must be a horrible sysadmin for solving a problem by eliminating the cause, and companies hiring me must be ashamed of themselves. My hardware must be shit (that's a common one with Windows users) despite being a business laptop and the guest system being a VM. Oh and I'm an idiot of course for complaining about such amazing system metrics in Windows.
I love Windows and its community...8 -
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.18 -
I had contact with the BenQ support recently.
On my small GV1 beamer, the auto switch off timer cannot be canceled by pressing a button. So I wrote them, that this is maybe a bug.
That was the answer:
"Thank you very much for your inquiry.
Insects entering the monitor through vents are a common problem that is not covered by the manufacturer's warranty as it is not a manufacturing problem.
This problem is known to all monitor manufacturers.
The cause of the problem is usually that the monitor is used in a dark environment without a secondary light source being activated.
If the insect is still alive, you can lure it out with a light source (the monitor should be turned off and cooled down).
If the insect is dead in the monitor panel, wait until it is completely dry. Then you can carefully press on the screen, next to the insects (avoid crushing them) and it should fall into the panel and leave the visible area.
Nevertheless, please send us a picture where we see the problem you are telling us, I inform you that the picture must be less than 2 MB in size."5 -
!rant just a question. Sorry in advance for the long post.
I've been working in IT in Windows infrastructure and networking side of things for my entire career (5years) and recently was hired for a role working with AWS.
We use Macs and we use *nix distros for days. I've only ever dabbled for 'funsies' before with Linux because every previous job I held was a Windows house and f*** all else.
I'm just wondering if anyone here might have some insights as to a great way to learn the Linux environment and to learn it the right way. I'm not the best Windows admin ever and will never claim to be, but I have seen stuff that other people have done that makes me want to swing a brick at someone's head. And I feel that with all of the setup wizards and the "We'll just do it for you." approach that Windows has used since forever it allowed enough wiggle room for people that didn't know what they were doing to f*** sh*t up royally. I'm not familiar enough with Linux to know if this is also a common problem. I know that having literal full-access to every file in your OS can cause a n00b like myself to mess up royal, thus the question about learning Linux the right way.
I vaguely understand the organization of the folders and file structure within Linux, and I know some very basic commands.
sudo rm -rf /*
Just kidding
But All of my co-workers at my new job are like mighty oaks of knowledge while I'm a tiny sapling. And at times I've been intimidated by how little I know, but equally motivated to try and play catch-up.
In addition to all of this, I really want to start learning how to program. I've tried learning multiple times from places like codecademy.com, YouTube tutorials, and codeschool.com but I feel like I'm missing the lesson that explains why to use a certain operation instead of another. Example: if/else in lieu of a switch.
I'm also failing to get the concept of syntax in certain languages I've tried before. Java comes to mind real fast.
The first language I tried teaching myself was C++ from YouTube. I ended up having a fever dream that night about coding and woke up in a cold sweat. Literally, like brain overload or something. I was watching tutorials for like 9 hours straight.
Does anyone know of a training resource that will explain, in terms a 5 year old would understand, what the code is doing and why? I really want to learn but I'm starting to lose steam cause I'm just not getting it.
Thank you in advance for any tips guys and gals. I really appreciate it. Sorry for the ridiculously long questions.5 -
I think the one of the more common reason for imposter syndrome is that a lot of smart people constantly get told as children the "you're so smart/capable, you can do everything!" too much, and when you hear it enough times, it gets to you, so you think everything is just easy. And then when they start hitting roadblocks, instead of helping or explaining that it's normal for things to be hard and it's normal to fail, usually parents and teachers and whatnot tell them "Oh it's okay, don't worry about it, you're smart, you'll get it" and so they at first it works, maybe it just takes more time but they manage, but as things get harder and they still put little effort because "don't worry, you're so smart, you learn so fast/easy" and as they find out more and more things they don't umderstand or don't know they start to feel a dissonance, which builds anxiety.
And this is where I thinks it actually starts: at some points there comes a situation where they either share this anxiety with someone or someone notices their worry, and(at least from what I've seen from others) usually the response they get is something along the lines of: "Nah, you're just worrying too much, you're smarter than you think, don't be so down on yourself, you need to worry less", which, maybe I'm wrong, but I'm not sure telling someone that thinks he has a problem that he doesn't have a problem, helps their worrying.
And on one hand the amount if things they don't get/know/understand or fail at grows(cuz you can't just be good at EVERYTHING, so the more things you know about, the more things you don't understand) while mentally still being in that "Wait a minute, you're smarter than this, you should be getting this!" mindset that's been drilled into them, and so at some point the illusion shatters, and they start to think "Maybe I'm not so smart after all", and because they think they were wrong about their level, they feel like they have "oversold" themselves in the past and that makes any past accomplishments feel like lucky accidents instead: "If I'm not actually smart, the things I did manage to achieve must've been just accidental", which makes them feel like they've lied to themselves and everyone else when they "took credit for an accidents" and that their life is just a snowball of pretending.
Now, is that actually a cause or is it another one of my crazy 1AM ramblings? I don't know xD
I'm not an expert in any of this and I don't really know any psychology so hell if I know if that's how any of this works but that's just my theory of one of the reasons why. *shrug*. I've had this theory for years, but I don't know.
It at least makes sense to me, but not everything that makes sense is true soooo.
Anyways, wall of text is over.
Oh, and for anyone struggling with imposter syndrome: I just want you to know, it's okay to fail, and it's okay to not know shit, especially in the dev industry where every "insignificant" detail can have an entire rabbit hole of expertise behind it, nobody can expect to know every part of it. And it doesn't make you any less smart no matter how much you fail. Tnis shit is hard, so I hope you stay strong and I hope you succeed in whatever it is you're struggling with.

I got a new computer recently. I got it with an evo 970. I tried installing the Samsung controller software so that I can view the health of the drive.
No go. Why?
Looked around and everywhere they are saying turn off raid. I checked in bios. Says my drive is not in a raid volume.
Okay, now what?
Look at manual of laptop maker. Says there is a mode that allows you to use either VMD or RAID on the drive. Apparently I was in VMD mode. I had already backed up the computer at this point. Yes, I suspected this was coming. So I changed the mode.
No boot.
Okay, I have Aomei backup and linux boot disk I made using Aomei. Linux boot disk won't boot... Well fuck.
Luckily I have my old computer and a Windows 10 install disk. I install Windows 10 again, install Aomei and proceed to try and restore.
4 hours later... I dunno how long. I went to bed.
Wake up and test.
No boot.
I try disk repair.
No go.
So I boot into Windows 10 install disk to look at partitions. 5 or 6 fucking partitions. It has installed 3 partitions into the space of one.
Delete all the fucking partitions. Cause fuck you!
Okay, lets try this again.
I make a window pe boot disk this time.
It boots.
I do restore while I am at work.
I get home.
No boot.
Check partitions and find only 2. Better than last time.
I try disk repair.
No go.
Search the net. Literally: "Aomei restore no boot"
Someone says, just assign drive letter with drive C using diskpart.
Seriously?! Disk repair couldn't figure this shit out by context?
Seriously doubting this solution.
Solution works...
Now, I am an engineer/programmer/computer genius. I have been learning how to fix this shit for over 30 years.
How the fuck is Joe Bloe ever going to fix an issue like this? I feel sorry for the technically un-inclined. I honestly don't know how neither Aomei nor Microsoft cannot solve restoring disk images by setting a drive letter. How did this not get backed up by Aomei? How did this not get detected as one of the most common problems with a disk restore? Why has this been a problem with Aomei restore for over 3 years? I love Aomei. It works most of the time. But this is terrible. The tech world is definitely a shit show at this point in time.
I also read that VMD actually makes the communication to the drive a bunch faster. Not sure if the samsung drivers do the same. So there may be a tradeoff. Oh well. I can see the temperature of my drives now! Woot!2 -
I just installed the interior IM app developed by my company's IT center, the way it uses to sync messages is almost common, downloads data from server and adds those conversation to client's window, and I am sure the guys who wrote this stupid thing invoked a same function like pushing message or something else, 'cause my cellphone vibrated like a Morse code machine w/ tons of Adrenaline injected when I press "Open", for almost fucking 1 minute.

Story about someone elses rant
A = coworker;
B = random guy from company, but from another office;
C = manager we like a lot, cause he has IT background;
A asked B about a problem, because B worked with the that thing. B answered I dont know. So A asked C, and told him, im asking you, because B said, he dont know. C went nuts and pulled a shitstorm on B, like who WTF do you think you are, that you cant give at least a hint to A on the problem or Cc someone who may know more about the problem.
what i wanna say is, shouldnt it be common sence if someone asks me about a problem i navigate him to a person, who knows more than me? Even if its the first day i the office, I know this is my team leader he should see the bigger picture of the problem, so ask him. But telling idk is like, go fuck your self. -
So, we're preforming a re-write an application. It's on an application (actual mortgage application, not 'app') that has 4 different entry points. We have the most common entry point converted to our re-written application with plans to have the next couple done over the next several weeks. Yesterday, the old version broke. It was under the impression that it could grab any row that matched the borrower and then check against a hash of that data to see if it could proceed. It can't. You can't hash data set 1 and expect it to be the same as the hash for data set 2. Not a thing. When asked, the only answer we could give right away was "We'll fix it, give us a couple of minutes" and "Sorry, bad {{appName}} is bad. We don't know root cause yet. We'll let you know when we do." Was pulled aside by my manager and told my answer was unsatisfactory and I shouldn't give answers like that. I get it, "Bad {{appName}} is bad" isn't great, but it's not like we were going to give that and leave it! We needed some time!2

Heres a fairly useless but interesting tidbit:
if i = n
then
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
then r%a will (almost*) always return 0. when n = floor(a/2) for the lowest non-trivial factor of a two factor product.
Thats not really the interesting bit though. The interesting bit is the result of r will always be some product with a *larger* factor tree that includes the factor A of p, but not p's other larger factor, B.
So, useless from what I can see. But its an interesting function on its own, simply because of what it does.
I wrote a script to test it. For all two-factor products of the first 1000 primes, (with no repeating combinations, so if we calculated say, 23*31, we skip 31*23), only 3262 products failed this little formula, out of half a million.
All others reliably returned 0 for the following..
~~~
i = floor(a/2)
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
r%a
~~~
The distribution of failures was *very* early on in the set of factors, and once fixed at the value of 3262, stopped increasing for the rest of the run.
I didn't calculate if some primes were more likely to cause a product to fail or not. Nor the factor trees, nor if the factor trees had any factors in common between products, or anything of that nature.
All in all I count this as a worthwhile experiment.
If you want to run the code yourself, I posted it to pastebin here:

Tried wolfram alpha just to see what it says, but apparently not much. Wish it could tell me more.40 -
Setting up a new docker environment for developing, its my first experience with it...
Guess who drew the lucky number to do the experiment...
Anyhow... Progress is slow, cause the sys admin refuses to cooperate, feeling threatened by the thought of us devs being able to do more ourselves...
Not to mention, our servers currently are a mess, there's no common ground, it's a mix of whatever was needed at the time, no documentation at all...
This is making the whole dockerizing process so damn painfull1 -
CBD oil has been used for years by individuals, who want to reduce their dependence on drugs. It was only recently that CBD was studied for possible pain relief by medical professionals. It is a highly important part of any healthy diet, because it is an important natural compound in plants.
Since the ancient Chinese first use marijuana as a medicinal treatment in 3000 BC, various cultures have used its healing properties, for a variety of medical conditions. However, in modern society, people often rely on pharmaceutical drugs to deal with their pain. One of the common problems with painkillers is that they can cause a number of side effects that can worsen your health. These side effects include depression, anxiety, insomnia, irritability, suicidal thoughts and more. Therefore, people have been turning towards natural remedies for their pain relief.
CBD oil has been shown to be very effective at reducing your pain, especially if you are taking narcotic painkillers. It is believed to stop or prevent the onset of physical discomfort, which means it does not provide temporary relief. As long as you are using it regularly, it can effectively help you overcome your pain.
In recent studies, medical professionals have suggested that the effectiveness of CBD was increased when it was combined with other herbs, such as ginger and eucalyptus. The main reason for this is that these two herbs have a great deal of medicinal qualities. Many people choose to combine these two natural ingredients to help reduce the amount of chemicals in their body, which will lead to a reduction in pain. By taking these products together, you will feel a reduction in pain faster than ever before.
You need to take care when using these products, however, as it is important to make sure that you do not take more than one product at a time. Taking too much of a product can actually create a higher chance of adverse reactions.
People have discovered that by taking CBD oil, they can relieve their pain, without relying on pharmaceutical drugs. If you have been using painkillers for a long period of time, try using a supplement to help you get the relief you are looking for.
Another great thing about CBD oil for pain relief is that it will help you maintain a healthy appetite. Studies have shown that when people eat foods high in CBD, such as hemp seeds and hemp oil, their bodies release natural hormones to help them fight off hunger.
If you are interested in finding out more about CBD oil for pain relief, check out. They can tell you about the various uses of the oil, the different strains of it and what to expect from it when using it.

We have an internal nuget package that wraps up the IConfiguration+ConfigurationBuilder for various .net core console/service apps (TL;DR, because people got creative), and it has a dictionary property for the common sections we use. AppSettings (for backward compatibility), ConnectionStrings, and ServiceEndpoints. If the need arises, I can add methods to return any type of object (no one has requested yet, we try to keep configs dead simple)
ex. var myDatabaseConnectionString = ConfigurationManager.ConnectionStrings["MyDatabase"];
Code review for someone who updated a .net framework app to .net core and they wrote their own IConfiguration wrapper for accessing the appsettings.json file, so I pointed out that we already had a library for that.
In the reply, he said he couldn't use our library because it had an 'AppSettings' property and since his appsettings.json file didn't have that section, he didn't want to cause a runtime exception.
OK, WTF...I even sent him a link to the documentation (includes explaining the backward compatibility part)...why the frack would you think because a property exists and you don't use it, that would cause some kind of runtime exception?
We have dozens of .net framework apps migrated to .net core with zero code changes and no one ever brought this up as a concern (because, why would they?)
Deep breath...ahhh...I respond that not having an AppSettings section in the appsettings.json file won't cause an exception, if you don't have one, don't need it, you don't have to use it.
He went ahead merged+committed his code anyway with his own IConfiguration+ConfigurationBuilder plumbing.
Code addiction is real kids...it's real.2
