New for avatars - emotions! You can now change your facial expression on your avatar to better capture your dev mood! Getting expressions working right turned out to be quite the undertaking due to the ripple effect of the various layers that each expression touched so our total layers just for men ballooned out from 300 layers to 1100. And @dfox re-architecting how layers work to handle the interconnectedness of expression meant tying together facial expression, skin tone, facial hair, and hair color to make sure everything stays in sync. It’s a fun new addition, I hope everyone enjoys!
I also want to apologize for the delay in getting this out, I meant to have this done ages ago but I got thrown a curveball at work and was laid off back in April and have been super stressed running around trying to find a new job for the past 3 months. I figured I’d have more free time to work on devRant, but hunting for work is so exhausting, it’s really taken its toll emotionally and financially (no unemployment benefits because according to my state even though we lose money every month “you’re still a corporate officer”). Things are finally looking promising on the job search front, and I expect once things get back to normal @dfox and I can get our release velocity back up, but until then, please bear with me.
P.S. If you have the resources, we certainly do appreciate your support with devRant++ Your monthly contributions really do make a difference! Thanks all!44 -
Best office prank: I was pretty young and naaive. Senior dev comes to me and says that it would be hilarious to slide a note under the women's bathroom door saying, "I know what you're doing in there". He says that the woman in there will think it's hilarious too. We work with her, she's very funny and laid back, so I go along with it, expecting to get a laugh. A few minutes go by and a different older women enters my cube. She's got the note! She works on the other side of the building so I don't know her too well but I can tell from the look on her face that she's pissed. I'm frozen with fear as my career flashes before my eyes.
I apologise perfusely and try to explain but she's not having it. After a while she goes back to her office not having accepted that it wasn't meant for her and that it was just a joke gone wrong. I spend the next two days apologizing every chance I get, hoping she won't go to HR. She remains stone cold until late on the second day. She couldn't take it anymore as her mouth reluctantly begins to crack a smile. At that point she drops the serious expression on her face and busts out laughing.
It turns out that the three of them planned the whole thing and executed flawlessly. I've never felt so relieved to be the butt of a joke.7 -
Hey everyone,
Merry Christmas to everyone who celebrates, happy holidays to everyone, and happy almost-new-year!
Tim and I wanted to reflect on the year devRant has had, and looking back, there are a lot of awesome things that happened in 2018 that we are very thankful for. Here are just a few of the ones that we thought of (this list is not exhaustive and I'm definitley forgetting stuff, so please comment about those!):
- After nearly a year in the making, the completely overhauled devRant web version was launched (https://devrant.com/rants/1255714/...)
- @linuxxx became the first devRant user to hit 100,000++! (https://devrant.com/rants/1157415/...)
- We once again pulled off the greatest April fools joke everrrr (https://devrant.com/rants/1311206/...)
- @trogus started making awesome devComics and http://devcomics.com was launched
- We added a feature to allow rant filtering by post type (https://devrant.com/rants/1354275/...)
- We made it so avatars could have expressions! (https://devrant.com/rants/1563683/...)
- We had a booth at TechDay New York and got to meet some devRant users! (https://devrant.com/rants/1394067/...)
- We made major backend architectural improvements - including spinning up a special high-powered-CPU web server to handle avatar creation and make the creation process much faster (https://devrant.com/rants/1370938/...)
- App stability: mainly Android - we fixed crashes, did a push-notif overhaul, and tried to continue making the apps better and more stable
- A record amount of devRant meetups were held, and we couldn't be more proud about that, and we thank every person who organized one! (just a few: https://devrant.com/rants/1588218/... https://devrant.com/rants/1884724/... https://devrant.com/rants/1683365/... https://devrant.com/rants/1922950/...)
We had a busy year, and despite some things going on for us personally and some setbacks around those, we think this was a very productve year for devRant and that we are going in the right direction. We're continuing to constantly evaluate feedback from members of the community to decide where to take the app next. We're fully committed to improving the devRant community in 2019 and we have a lot of ideas about how we can do that. We're working on some things, but we're not really announcing them yet, so please sit tight for those :) In the meantime, feel free to let us know what you'd like to see improved/added the most as we always like to get updated feedback from the community.
As always, thank you everyone, and thanks for your amazing contributions to the devRant community!
Looking forward to 2019,
- David and Tim26 -
My 7 year old sister: Why do you always use the duck? Go on google.
Me: Because Google spies on you.
Sister: How??
Me: *too tired to explain* by magic. Whatever you go on, they'll know.
Sister: *shocked expression* WHAT? *proceeds to ask a million questions.*
Sister: What do I do now?
Me: Use the duck (she calls ddg "the duck.")
Then a few hours later, I saw her playing Y8 on DuckDuckGo. I'm so proud of her. :)
Now if only I can convince my 15 year old little brother to do the same thing. He doesn't seem to care at all.55 -
Me: Wanna see this website I built this weekend?
Friend: Yeah, sure.
Me: I connected a bunch of APIs so you can snap a photo of yourself and get a recommended song based on your facial expression. Pretty cool, right?
Friend: *thinking* ... I think you should change the size of that button, and the colors are pretty bad, dude.
Every time I show my non-tech friends anything I get this kind of feedback :/19 -
To be or not to be.
Whenever you are stuck with something in life, ask that question to yourself.
Because
2b || !2b
Is a Boolean expression which will always be true. So asking that question will lead you to true self.

People's expression when I explain them devRant:
"..so, it's a social media for the nerdy antisocials"7 -
Another day at CS Class :
Friend : " Lol! Is that Linux? "
Me : " Yeah why? "
Friend : " That shit sucks man, go use Windows! "
Me : *im going to kill you face expression*12 -
Fuck off with your shit ass semicolon jokes. You searched for semicolon for 4days? Fucking retard with a sack of balls instead of eyes can understand that he's missing a semicolon in matter of seconds. It's going to be 2018 soon. Get a fucking IDE that says that you are missing a fucking semicolon. The error literally fucking says "; expected at the end of expression". Ugh...? I wonder what that means... Maybe something is wrong with my operating system or my PC. Fuck off with that shit. Try debugging some systems that have 2files with 15k lines in each of them with 200fields and all of them strings both with empty default constructors. Semicolons... My ass..14

Assembly: He’s the nerd. He speaks very quickly and uses short sentences. Very few people talk to him. He’s considered to be an autist asperger by a majority of the class because he finishes the exams so quickly it’s insane and he faces a lot of difficulties in speaking with others. He’s at school but already dressed like an engineer.
Ada: She’s a foureyes nerd. When she gets the answer she’s doesn’t make any mistake. Ada often corrects the teacher when she writes a line a little ambiguous. She’s building a rocketship in her backyard and she’s always speaking about this weird hobby.
Python: He’s Mr Popular. He likes skate, brags about all the parties he’s invited to. He’s good in all the subjects taught in class but he’ll do them a bit slower than the others. Everyone loves him because he explainsthings so well, sometimes the teacher herself asks Python to explain some part of the course. He’s dressed with a hoodie, a baggy and glasses on the top of the head ;)
Java: She is one of the toppers of the class and very popular. She’s very good in all the topics. The teacher loves her but she’s a very talkative person.
Scala/Kotlin: They are twin sisters and the best friends of Java. Unfortunately, they are not as popular and it’s often Java who takes the lead in the group. It’s very difficult to distinguish one from another. Both are far less talkative than Java but Scala speaks a bit differently than Kotlin and Java.
C: He’s the topper of the class. He’s so fast in completing the exams that the teacher really thinks he’s copying Assembly’s work. He has a little brother C++ and they share a lot in common together. He’s the chess major and often plays chess with Assembly and his big brother.
Go: He’s the new kid on the bloc. He doesn’t like C++ and his friends and he wants to prove he can do better than them. Of course, he prefers playing Go over Chess.
APL: He’s a lonely guy. No one understands him when he speaks. Even the teacher is surprised when APL shows a correct answer after several lines of incomprehensible pictograms. People think that he was born in a foreign country… or a foreign planet ?
HTML/CSS: These twin brothers are very different. One is dressed in black and white and the other is dressed with everything except black and white. HTML is very talkative and annoying and the CSS is very artistic. CSS is the best student in Art lessons and HTML performs well in written expression.
LaTeX: She’s friend of HTML. The teacher likes her because she has a gift of writing. LaTeX likes the mathematical courses because she can draw fancy greek letters. The teacher knows this well and she is often asked to write a formula on the black board.
VBA: He’s in the back, looking through the windows. Not really interested in the courses taught in class. In the exams, he answers always with a table.
C#: He’s in the back playing yet another game on his smartphone. He likes being next to the windows also.
JavaScript: People often mix up Java and JavaScript because they have a similar name. But they are definitly not the same. Javascript spends a lot of time with HTMLand CSS. He’s as artistic as CSS but he prefers things that move. He likes actions and movies. CSS dreams to be a painter wheras JavaScript wants to be a film-maker.
Haskell: He’s a goth. Dressed up in dark. Doesn’t talk to anyone. He doesn’t understand why others write pages when he can write a couple of lines to answer the same question.
Julia: She’s the newest student here. She doesn’t have any friends yet but her secret aim is to be as popular as Python and as fast as C.

So today I was with my I guess 9-10yo cousin. He was playing clash of clans.
I told him, “you can also make this type of games”.
After this he was stared at me for like 25-30sec his face expression was awesome. Then said “seriously? I thought games are developed on a certain place where all the games are made.”
I said “no anyone can create games if you know how to code and all.”
After that multiple questions was on the way and I answered all for him.
But he totally amazed with this knowledge. And I felt good to.10 -
Okay i'm done - YOU FUCKING ANDROID STUDIO MORONS. Being at a high level in C++, I tried to do some android coding. THERE ARE FUCKING NO GOOD TUTORIALS, NO GOOD DOCS, HECK, THE SELF GENERATED CODE OF THE IDE IS WRONG: WHAT THE FUCK IS GOING ON YOU FUCKING MORONS?
oh wait, let me first import android.widgets.rant;
or was it android.widgets.devrant.rant; or was it android.dr.rant.RantManager;?
Oh wait, I know lets search the docs?
OH WAIT THE DOCUMENTATION DOESNT HAVE THAT.
NOW HOW ABOUT I JUST TRY THE EXAMPLE CODE? WELL UH-UH! YOU HAVE TO FIND OUT YOURSELF WHAT TO IMPORT IN ORDER FOR IT TO WORK. ALSO, WHAT FUCKING UP WITH THAT PERMISSION SYSTEM? ITS SO BADLY DOCUMENTED!!!
Oh wait, I'm sure that I have to change something in this file... or was it that other file?
GOD
how dare they have style and design guidelines?
MORONS!
I will resort to implement my app idea in godot, idc anymore... I don't want to burn out because I used the "official high standard" tech.
it definitely isn't high standard and definitely not good. Thank you morons@google
THANK YOU FOR NOTHING
A FRAMEWORK WHERE I NEED 2 DAYS TO FIGURE OUT TO ADD EVENT LISTENERS TO MY THINGS IS DEFINITELY NOT ONE I'D LIKE TO USE.
also, whats up with
AudioRecord (int audioSource, int samplerateInHz, int channelConfig, int audioFormat, int bufferSizeInBytes);
ARE WE BACK IN THE C ERA? CAN'T YOU BE BOTHERED TO IMPLEMENT SOME SIMPLE FUCKING ENUMS????
WHATS THE POINT OF AN OOP LANGUAGE IF YOU ARE GOING TO USE IT LIKE C?
Oh wait I found a tutorial ... First trigger: "java scripts". Second trigger: this guy LITTERALLY ONLY TEACHES YOU HOW TO PLACE WIDGETS ON THE CANVAS. THANKS FOR NOTHING SHERLOCK!
Oh btw: did you know that android studio gives the best error messages?
"Error: illegal start of expression"
NO ERROR MESSAGE - NOTHING!
YOU BETTER USE THE IDE OR YOU GO HOME YOU FUCKER!!!
Oh and btw: if you want to read the best documentation - the code itself YOU GOTTA AGREE TO OR TERMS OF SERVICE!!!! WE DONT WANT ANYBODY TO BECOME SUCCESSFUL WITHOUT US KNOWING!!!!!
THANK YOU GOOGLE FOR NOTHING!
YOU FUCKERS!
thanks godot for *atleast* existing. You are the... last pick i'd pick, but :shrug:, I have experienced android studio now.
If anybody has any advice on what to use instead, please go ahead. And you better not tell me how good you are at android studio. I DONT CARE ABOUT WHAT YOU CAN IMPLEMENT IN ANDROID STUDIO. I JUST WANT SOMETHING THAT IS USABLE WITHOUT HAVING TO BE EXTRA CAREFUL WHEN DOING *ANYTHING*!!!!
fuckers.48 -
Guy from work: "I have a messy coding style ¯\_(ツ)_/¯".
No, you have a bad coding style. Your repetitive uncommented spaghetti code isn't an artistic expression of your quick imaginative mind jumping from thought to thought. It's a horrible mess that shows me that either you can't do any better or you don't care.8 -
When I was in high school, the IT had the bright idea to use the same username/password for each machine in our site, and there was this jerk who knowing this, would occasionally SSH into the computers of the other classmates and wget porn mp4s to their home directory to embarrass them, as some sort of weird-ass prank.
So, in order to give him a lesson, I one day had logged in and set a rule on the class' router to forward all port 22 traffic back to his own IP address, and had SSHed into his machine, aliasing wget with a full-screen kiosk mode chrome, followed by a force disable of the USB HID devices.
It might have been less awkward and he might have seen less scared, if it wasn't for the fact that I had also remotely set his machine to maximum volume, and the teacher wasn't in the middle of a lecture. 😏
To this date, his expression is the most precious reaction I have ever seen.9 -
You what's been pissing me off this week. The press and social media coverage of this Google guy's gender memo.
Almost every outlet has him saying:
"Women are inferior coders because of their biology"
He ABSOLUTELY does not say this anywhere. He only states that basically less women are attracted to the industry. He doesn't comment at all on the quality of the Women who do go into tech.
It astonishes me the utter ignorance of the media and how they can just print these ignorant errors / lies.
I would wager that most if not all of them never even read his memo.
I am really fucked off by this social media keyboard warrior driven world we live in.
Apparently we value freedom of speech and freedom of expression above all else... UNLESS you say something that pisses off the social media justice warriors. In that case you will be publicly crucified and your life / career will be destroyed.
The annoying thing is in this particular case he didn't even say what they are saying he did.43 -
My own language, hence my own parser.
Reinvented the regular expression before realizing it already existed (Google didn't exist at the time).
I'm a living reference for regular expressions since then.7 -
Watching a tutorial.
* Uses the mouse in order to select and format code, instead of the shortcuts VS code provides
* Does multiple "bool == true"-comparisons
* Doesn't use string interpolation and makes unnecessary .toString() calls
* Adds fucking parentheses around the whole fucking expression he wants to assign
value = (expression)
* Explanations so vague, the EU wants to hire him to reform the internet
Fucking waste of time even on x2.25 speed.10 -
"I want blah blah blah and I need it now! There's a commercial expression called TIME TO MARKET!"

So today I was working on some PowerShell scripts and I get a question from a colleague
Colleague: So, How's your girlfriend doing ?
Me: "You cannot call a method on a null-valued expression" -ForegroundColour "Red"

Totally worth it! -

Worst experience with cs profs? Oh boy....
Databases lab: "You'll need to work of this snippet, if your IDE tells you it's deprecated you don't need to care about it"
If you want to imagine the quality of the code base we were expected to work upon just think about that attached xkcd comic, basically an undecipherable black box.
The instructions where at the same time micro managing everything (he gave us frickin variable names to use, and no good ones, no the database connection had to be called datbc, yeah very descriptive) and yet so obfuscated that I'm not completely sure he didn't resurrect Kant himself to ghostwrite for him.
He also didn't like us to use any Java feature that was to 'modern', for example for each loops since "they offer no benefit over normal for loops".
Further, everything we wrote had to be documented with a relationship diagram and a uml. So far no problem if he hadn't invented his own flavor of both (which can be read about in his book).
Oh, and he almost failed me because I used a lambda expression in his 'code on paper' exam and this "arrows are a C command" I "must have been confused"... which is glorious coming from the guy who can't get operators and commands straight.1 -
It's how my co-workers and I quit,
When the incompetent COO joined the previous company I worked for (my previous rants contain stories about him)
Five of us from a seven people team found better jobs (salaries and company wise)
Walked up to the CEO and handed the resignations one after another, stating our reasons for leaving
COO's face was like a coin that got run over by a train2 -
Small Me(m): learning some basic code
Senior Dev(d): *walks by and sees my code*
m: hey got any advice on this?
d: learn to use regular expression. *walks away*
m: 30min later... *Mind blown*
And coffee of course ☕2 -
Today I wrote a regex expression that worked on the first try. Today I learned that the hardest code to debug is bugless code.6

After working over 14 years as it-systemadministrator and developer for a city government I finally quit today and switched into a start-up. Lower wage, vacation days and many more "downsides"...but I am allowed to follow my passion and create something that matters. I'm afraid and super jacked. Wish me luck :)
tl;dr quit job to get complete expression. afraid and jacked at once :)5 -
Even after our last cd="exit" alias prank, my co-worker forgot to lock his computer today.
I told him he had forgot to lock it.
His facial expression was priceless.

A small bug is found.
Chad dev:
😎 *Exists*
> Writes a simple ad hoc solution in a few lines
> Self documenting code with constant run time
> No external dependencies needed
> Fixes the bug, easy to test and does not introduce any new issues
That guy nobody likes (AKA. regex simp coder):
🤡 'This can be "simplified" into oNE LiNe'
> Writes a long regex expression that has to line wrap the editor window several times
> Writes an essay in the comments to explain it's apparent brilliance to the peasant reader
> Exponential run time (bwahahah), excessive memory requirements
> Needs to import additional frameworks, requires more testing that will delay release schedule
> Also fixes bug but the software now needs 2x ram to run and is 3x slower
> Really puts the "simp" in simplified, but not the way you would expect26 -

I'm working on a programming language with a "bytecode" interpreter and a compiler that translates source code to said bytecode and... it sort of actually works!
I want to recreate an Erlang-style environment, currently you can write functions, call C++ functions via wrappers, have immutable-only values, and it has no explicit control structure apart from statement sequencing and the if-expression because I want to make it as functional as possible. Next thing on the list is to add a green threads implementation and ability to spawn and send messages to processes.
Still a WIP and heck even design-in-progress.
Now for the rant:
I'm using CMake for building C++ (interpreter) and Stack for Haskell (compiler) and I've been trying to get them to talk to each other for hours because I want CMake to manage the Stack build too and shove all the executables into one place. CMake documentation is weird and Stack isn't too helpful either, so I guess I'll just spend another few hours trying to get Stack to fuckin reveal its build directory to CMake and/or build to a given directory. Ugh.8 -
Me (as a Senior developer): How will you solve this problem using regular expression?
Junior developer: *Explains*
Me: Good
Junior developer: I truly feel like a programmer when I code regular expressions

Hey guys,
this rant will be long again. I'm sorry for any grammar errors or something like that, english isn't my native language. Furthermore I'm actually very sad and not in a good mood.
Why? What happened? Some of you may already know - I'm doing my apprenticeship / education in a smal company.
There I'm learning a lot, I'm developing awesome features directly for the clients, experience of which other in my age (I'm only 19 years old) can only dream.
Working in such a small company is very exhausting, but I love my job, I love programming. I turned my hobby into a profession and I'm very proud of it.
But then there are moments like the last time, when I had to present something for a client - the first presentation was good, the last was a disaster, nothing worked - but I learned from it.
But this time everything is worse than bad - I mean really, really worse than bad.
I've worked the whole week on a cool new feature - I've done everything that it works yesterday, that everything gets done before the deadline of yesterday.
To achieve this I've coded thursday till 10pm ! At home! Friday I tested the whole day everything to ensure that everything is working properly. I fixed several bugs and then at the end of the day everything seems to be working. Even my boss said that it looks good and he thinks that the rollout to all clients will become good and without any issues.
But unfortunately deceived.
Yesterday evening I wrote a long mail to my boss - with a "manual". He was very proud and said that he is confident that everything will work fine. He trusts me completly.
Then, this morning I received a mail from him - nothing works anymore - all clients have issues, everything stays blank - because I've forgotten to ensure that the new feature (a plugin) and its functionality is supported by the device (needs a installation).
First - I was very shoked - but in the same moment I thought - one moment - you've written an if statement, if the plugin is installed - so why the fuck should it broken everything?!
I looked instant to the code via git. This has to be a very bad joke from my boss I thought. But then I saw the fucking bug - I've written:
if(plugin) { // do shit }
but it has to be if(typeof plugin !== 'undefined')
I fucked up everything - due to this fucking mistake. This little piece of shit I've forgotten on one single line fucked up everything. I'm sorry for this mode of expression but I thought - no this can not be true - it must be a bad bad nightmare.
I've tested this so long, every scenario, everything. Worked till the night so it gets finished. No one, no one from my classmates would ever think of working so long. But I did it, because I love my job. I've implemented a check to ensure that the plugin is installed - but implemented it wrong - exactly this line which caused all the errors should prevent exactly this - what an irony of fate.
I've instantly called my boss and apologized for this mistake. The mistake can't be undone. My boss now has to go to all clients to fix it. This will be very expensive...
Oh my goodnes, I just cried.
I'm only working about half a year in this company - they trust me so much - but I'm not perfect - I make mistakes - like everyone else. This time my boss didn't looked over my code, didn't review it, because he trusted me completly - now this happens. I think this destroyed the trust :( I'm so sad.
He only said that we will talk on monday, how we can prevent such things in the feature..
Oh guys, I don't know - I've fucked up everything, we were so overhelmed that everything would work :(
Now I'm the looser who fucked up - because not testing enough - even when I tested it for days, even at home - worked at home - till the night - for free, for nothing - voluntary.
This is the thanks for that.
Thousand good things - but one mistake and you're the little asshole. You - a 19 year old guy, which works since 6 months in a company. A boss which trusts you and don't look over your code. One line which should prevent crashing, crashed everything.
I'm sorry that this rant is so long, I just need to talk to you guys because I'm so sad. Again. This has happend to frequently lately.16 -
!rant !dev
True story. Some years ago I worked, for a network manufacturer in the support department. One of me jobs was to help end-customer (private people) over the phone, who could not get online.
One day a 60+ year old woman called the support line, because se could not get on the Internet. And because our name was on the router, she called our support.
A colleague of mine took the call, and we could quickly see by his expression the it was "One of those calls". The minutes went by and they had gotten no closer to a solution after 45 min.
That was when I herd my colleague say "Well from what you tell, all the settings here are fine. Can you please close all the windows, so we can look at other settings". My colleague the looked weird and said, "She just told me it takes some minutes to close all the windows, so please hang on.".
After 2 min time the woman came back to the phone and said "I have now closed all the windows in the house, except one ceiling window that only my husband can reach. Hope it doesn't matter".2 -
The time when we were not aware with advance features of IDE and version control.
(3-4 days before the project demo)
Me: This code was working fine last time. Now it is not compiling. Has anyone did some changes?
Team member: I corrected some spellings. So that our teachers don't correct us at the time of demo.
Me: (shocked, expression less ) We demo the application not the code. And you have not corrected on all the places.
Team member: You should do the rest.
(Based on true story) -
Thinking of making a calculator app that is implemeted with microservices.
Like multiplication service calls addition service, and power service calls multiplication service, and expression service can call all of those, etc.
Next I need to figure out how to add AI to it12 -
Ever heard of event-based programming? Nope? Well, here we are.
This is a software design pattern that revolves around controlling and defining state and behaviour. It has a temporal component (the code can rewind to a previous point in time), and is perfectly suited for writing state machines.
I think I could use some peer-review on this idea.
Here's the original spec for a full language: https://gist.github.com/voodooattac...
(which I found to be completely unnecessary, since I just implemented this pattern in plain TypeScript with no extra dependencies. See attached image for how TS code looks like).
The fact that it transcends language barriers if implemented as a library instead of a full language means less complexity in the face of adaptation.
Moving on, I was reviewing the idea again today when I discovered an amazing fact: because this is based on gene expression, and since DNA is recombinant, any state machine code built using this pattern is also recombinant[1]. Meaning you can mix and match condition bodies (as you would mix complete genes) in any program and it would exhibit the functionality you picked or added.
You can literally add behaviour from a program (for example, an NPC) to another by copying and pasting new code from a file to another. Assuming there aren't any conflicts in variable names between the two, and that the variables (for example `state.health` and `state.mood`) mean the same thing to both programs.
If you combine two unrelated programs (a server and a desktop application, for example) then assuming there are no variables clashing, your new program will work as a desktop application and as a server at the same time.
I plan to publish the TypeScript reference implementation/library to npm and GitHub once it has all basic functionality, along with an article describing this and how it all works.
I wish I had a good academic background now, because I think this is worthy of a spec/research paper. Unfortunately, I don't have any connections in academia. (If you're interested in writing a paper about this, please let me know)
Edit: here's the current preliminary code: https://gist.github.com/voodooattac...

math be like:
"Addition (often signified by the plus symbol "+") is one of the four basic operations of arithmetic; the others are subtraction, multiplication and division. The addition of two whole numbers is the total amount of those values combined. For example, in the adjacent picture, there is a combination of three apples and two apples together, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" i.e., "3 add 2 is equal to 5".
Besides counting items, addition can also be defined on other types of numbers, such as integers, real numbers and complex numbers. This is part of arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can be performed on abstract objects such as vectors and matrices.
Addition has several important properties. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, the order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.
Performing addition is one of the simplest numerical tasks. Addition of very small numbers is accessible to toddlers; the most basic task, 1 + 1, can be performed by infants as young as five months and even some members of other animal species. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. Mechanical aids range from the ancient abacus to the modern computer, where research on the most efficient implementations of addition continues to this day."

I quit abusive relationship. I quit smoking. I quit vaping salt nicotine, yes, the one that vape bloggers tell you is impossible to quit. I overcame opioid drugs addiction that developed when I recovered after a surgery back in 2015.
My last addiction is sugar. Yesterday night was the night when I ate about 100 grams of it in one take, feeling like I need more and more to take that hunger away. It felt EXACTLY like when I was hitting my 50mg vape literally every 20 seconds no matter the headache and dizziness.
I’m already insulin-resistant. After I’ve eaten all that sugar I felt really thirsty and then it hit me. I don’t want diabetes. I don’t want to inject myself. And I’m already insulin-resistant. It’s not me who crave sugar, it’s my internal animal and it only understands the language of pain and fear of death.
After I quit it, I’m officially a superhuman. Addicted to nothing but self-expression. That’s what I like, that’s who I naturally am.12 -
New developers(5-6 years experience) these days are so pathetic. They dont have any sense of code review. All they want is to put their opinion out without giving any thought.
I had a PR for review today which contains mock specification to match a regular expression and return the corresponding response
The regular expression I put was
104000(02|06|20|48)
Now, this guy comes and puts a comment that we could "simplify" as 104000\d{2}
I replied, the ending digits are not contiguous. The specific pair of digits have to match for these mocks.
Then this guy replied, then we could simplify as 104(0{4}(2|6)l0{3}(20|48)).
I said, I cannot understand how that is simplification. Why do we need such a complex regex to match something very straight forward.
And the guy replied, we should be writing proper regexes, otherwise we could just specify everything explicitly.
I was like WTF man. You try deciphering this next week without taking at least a minute to know which values are matched.
Anyhow, another senior person approved my PR, and I merged it.12 -

How to teach a 5 yr child to code?
The method is simple you don't need to teach him to code just help him to understand the method to execute a task. It took me years to understand that coding is a way to express what you want to say- the method and also is our expression. So, if you can help him/her to understand what to express, then I believe the method on how to express is totally unworthy. He/she can say printf("I know this") or print("I know this") or #I know this or he/she may create a new language.

Bard: <blah blah blah> Would you like me to run a reverse phone lookup on that number for you?
Me: Yes
Bard: I'm just a language model, so I can't help you with that.
Me: Then why did you ask?
Bard: "I understand that you don't need me to run a reverse phone lookup, and that's perfectly fine. I just wanted to offer the service in case you were interested."
I tweaked the question and Bard responded with a Python script and a phone number regular expression.

I’m working with a “senior” developer with a full decade more experience than me who didn’t know that short-circuit evaluation works differently for OR than it does for AND. He argued with me for a good hour and a half that in the expression (a || b), b would never be evaluated if a is false — and that this couldn’t possibly be the source of the bug he was trying to fix.

PHP arrays.
The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.
What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.
This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.
You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.
Bonus PHP trivia:
Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.
`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.
Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.
Strings can be indexed with negative integers. Arrays can't.
ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.
`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.5 -
Why the fuck does Arduino use C++ macros for min, max, abs, etc. ???????
---
For those who don't know what a macro is, basic example:
#define abs(x) (x > 0 ? x : -(x))
Which looks like a function, but instead abs() will be replaced by the expression and all x will be replaced literally with what you pass to abs
So
abs(i++)
would evaluate to
(i++ > 0 ? i++ : -(i++))
which would call i++ twice
---
I guess I will have to double check every built in function and rewrite it if it's a macro -_-. Not taking any chances. Btw all Arduino functions are in one big file, so now I have to pollute my code with namespaces.
Macros can be great but what the fuck.16 -

Hi
I'm an active user here so I know most of you.
I created a throwaway because I consider this a sensitive subject to me, and don't want people here to think I'm crazy.
I have some form of ocd but I don't know exactly which subtype it is.
It's not really something that makes my life impossible, but it makes me feel awful from time to time.
the way it works is that I imagine accidents happening to me or people I love, and I get triggered more if they are potentially caused by a mistake from me and they feel very vivid in my mind.
It's awful and terrifying.
Being close to anything that could cause harm is a trigger:
heights without any type of fall protection, knives, elevators, escalators, being on a plane
Being close to/in said objects/situations can start a clip in my mind as if I was watching a final destination movie.
This is a stronger obsession if it happens because of my fault, like tripping with my kid in my arms, or fumbling a knife while I cook.
Sometimes I react by curling and doing a painful expression and twitching a bit, even in public.
it's terribly painful.
i look like a crazy person, although considering what I'm writing, i probably am. It's just that I feel very scared of strangers in public noticing what I'm doing and finding out I'm crazy.
sometimes I get scared of the possibility of me being an actual psycho like the ones you see on crime shows.
as far as i know i think im normal in terms of compassion, empathy to others and never had any interest in harming others.
it's just part of the ocd, being hypervigilant of me, obsessing over me causing harm either accidentally or deliberately.
I'm also very scared of puking in public, or even worse, in front of friends.
Specially true if you're eating but you're seated in a spot where there's no way out except if everybody gets up.
I start by becoming self conscious of the possibility of puking, and sometimes I twitch a bit too, while trying to not look too crazy and joping that the next bite doesn't cause me to projectile vomit over people.
I hate this shit.15 -
So I have to fix this motherfucking insane regex with over 1k chars in it ...
This fucking shit is not maintainable and there are no comments or any other sort of documentation.
And this bullshit was not build via code so that bastard wasted weeks of time to develop that shitty expression by hand on a online regex tester website.
So I have 3 options:
1. Reverse engineer everything and waste my precious time
2. Delete that shit, analyze the input and write the regex via code instead of creating it by hand
3. Look for that "super duper clever" dev and break his legs.
I think option 3 suits me best.
And for you dear reader, if you are regexphile, enjoy this gigantc regex with >16k chars:

The saying "Perfect is the enemy of done" is so much BS.
The war on perfection is the enemy of artistic expression.
Look at old world architecture vs modern crap. Crafts are no longer a thing but stuff is only made as effeciently as it can be for the greedy and impatient.
The artists and craftsmen of old knew well that perfect was achievable and constantly strove to be more and more perfect in their arts and by side effect on themselves. In this mad world we've lost that to the pragmatists who see no value in the art of perfection or in those who do not value those who do.
The "doneists" can go fuck themselves. Perfectionism is where true artistic expression is at.14 -

This wasn't an interview, but a massive rejection which I've never forgotten...
I was working beneath a director from hell. South African, very intimidating. If I was not able to dictate my work, he would give me an expression like I had just kicked his dog.
I think at the time, I had threatened the development manager when I had challenged the way we were running database queries and linked processes.
The director had pulled me into his office one day and said to me, literally, "not everyone can do what they want to do, if they are not good at it". Like seriously, what the fuck... I was doing a lot more than others even more senior to me, and I had just come on board learning the language on the fly (4th Dimension, don't ask...).
I digress... My heart just completely sank and I was left speechless. Two jobs later and I could give him the big finger.

Can someone explain the philosophy of the "not for me" downvote?
There are many things that are "not for me" in life, but, presumably, this action executes a global downvote on the post/comment---which is pretty much an expression of "not for anyone".
If this action were to train a recommendation engine---so I get recommendations that like-minded people see---then great. But why should that result in a public downvote?
I don't go up to people in the bar and say "Drinking Guinness? Not for me, mate." As an adult, I understand that my preferences are not universal.
Personally, I can't square the idea of "not for me" with its consequence of a public downvote.

dev, ~boring
This is either a shower thought or a sober weed thought, not really sure which, but I've given some serious consideration to "team composition" and "working condition" as a facet of employment, particularly in regard to how they translate into hiring decisions and team composition.
I've put together a number of teams over the years, and in almost every case I've had to abide by an assemblage of pre-defined contexts that dictated the terms of the team working arrangement:
1. a team structure dictated to me
2. a working temporality scheme dictated to me
3. a geographic region in which I was allowed to hire
4. a headcount, position tuple I was required to abide by
I've come to regard these structures as weaknesses. It's a bit like the project management triangle in which you choose 1-2 from a list of inadequate options. Sometimes this is grounded in business reality, but more often than not it's because the people surrounding the decisions thrive on risk mitigation frameworks that become trickle down failure as they impose themselves on all aspects of the business regardless of compatibility.
At the moment, I'm in another startup that I have significantly more control over and again have found my partners discussing the imposition of structure and framework around how, where, why, who and what work people do before contact with any action. My mind is screaming at me to pull the cord, as much as I hate the expression. This stems from a single thought:
"Hierarchy and structure should arise from an understanding of a problem domain"
As engineers we develop processes based on logic; it's our job, it's what we do. Logic operates on data derived from from experiments, so in the absence of the real we perform thought experiments that attempt to reveal some fundamental fact we can use to make a determination.
In this instance we can ask ourselves the question, "what works?" The question can have a number contexts: people, effort required, time, pay, need, skills, regulation, schedule. These things in isolation all have a relative importance ( a weight ), and they can relatively expose limits of mutual exclusivity (pay > budget, skills < need, schedule < (people * time/effort)). The pre-imposed frameworks in that light are just generic attempts to abstract away those concerns based on pre-existing knowledge. There's a chance they're fine, and just generally misunderstood or misapplied; there's also a chance they're insufficient in the face of change.
Fictional entities like the "A Team," comprise a group of humans whose skills are mutually compatible, and achieve synergy by random chance. Since real life doesn't work on movie/comic book logic, it's easy to dismiss the seed of possibility there, that an organic structure can naturally evolve to function beyond its basic parts due to a natural compatibility that wasn't necessarily statistically quantifiable (par-entropic).
I'm definitely not proposing that, nor do I subscribe to the 10x ninja founders are ideal theory. Moreso, this line of reasoning leads me to the thought that team composition can be grown organically based on an acceptance of a few observed truths about shipping products:
1. demand is constant
2. skills can either be bought or developed
3. the requirement for skills grows linearly
4. hierarchy limits the potential for flexibility
5. a team's technically proficiency over time should lead to a non-linear relationship relationship between headcount and growth
Given that, I can devise a heuristic, organic framework for growing a team:
- Don't impose reporting structure before it has value (you don't have to flatten a hierarchy that doesn't exist)
- crush silos before they arise
- Identify needed skills based on objectives
- base salary projections on need, not available capital
- Hire to fill skills gap, be open to training since you have to pay for it either way
- Timelines should always account for skills gap and training efforts
- Assume churn will happen based on team dynamics
- Where someone is doesn't matter so long as it's legal. Time zones are only a problem if you make them one.
- Understand that the needs of a team are relative to a given project, so cookie cutter team composition and project management won't work in software
- Accept that failure is always a risk
- operate with the assumption that teams that are skilled, empowered and motivated are more likely to succeed.
- Culture fit is a per team thing, if the team hates each other they won't work well no matter how much time and money you throw at it
Last thing isn't derived from the train of thought, just things I feel are true:
- Training and headcount is an investment that grows linearly over time, but can have exponential value. Retain people, not services.
- "you build it, you run it" will result in happier customers, faster pivoting. Don't adopt an application maintenance strategy

I found this on a wiki with Haskell Humor... it's interesting...
How to Shoot Your Self in the Foot With Haskell: Putting the unsafe in unsafePerformIO!
You shoot the gun, but the bullet gets trapped in the IO monad.
Couldn't match expected type 'Deer' against inferred type 'Foot'.
While compiling your program the compiler produces a type error long enough to overflow a kernel buffer, overwrite the trigger control register and shoot you in the foot.
After trying to decipher the type errors from the compiler, your head explodes.
After you've finally found a way to circumvent the type system and shoot yourself in the foot, Oleg appears out of nothing and shoots you in the foot for coming up with it before him.
You shoot the gun but nothing happens (Haskell is pure, after all).
Your foot is fine, until you try to walk on it, at which point it becomes mangled.
You have a shootFoot function which you've proven correct. QuickCheck validates it for arbitrary you-like values. It will be evaluated only when you end up at the hospital. You hope this doesn't come to pass, as it actually returns a bullet-ridden copy of yourself and you don't want to be garbage-collected.
foreign import ccall "shootparts.h shootfoot" shoot_foot :: Gun -> Programmer -> IO ()
shootSelfInFoot = unsafePerformIO . shoot . foot $ self -- Shoot self in foot 0 or more times depending on evaluation order
No instance for (Target Foot)
arising from use of `shoot' at SelfInflictedInjury.hs:1:0
Possible fix: add an instance declaration for (Target Foot)
In the expression: shoot foot
You go to shoot yourself in the foot but the bullet is in the ST monad and the gun is in the IO monad, so you can't.
You ask Haskell to shoot you in the foot but by the rules of lazy evaluation you don't need the result yet so it doesn't happen.
You decide to shoot yourself in the foot but get distracted devising a ballistics algebra and wondering if you can do the calculations in the type system.
You want to shoot yourself in the foot but realize there is no Gun datatype so use Arrows instead.
You shoot in the direction of your foot, but since you are inside the STM monad you can just retry until you figure out what to do.
You shoot yourself in the foot, but you are perfectly fine as long you just don't evaluate the foot.
You shoot yourself in the foot, but nothing happens unless you start walking.
Don't forget about memory consumption! If you don't look, the bullet causes heap overflow. If you look, the bullet causes stack overflow.
You *appear* to have deliberately shot yourself in the foot, and yet your program actually runs perfectly OK due to lazy evaluation. (So long as you remember to not look at your foot...)
You aim the gun at your foot, pull the trigger and remove the clip. When you look at your undamaged foot, the hammer clicks on an empty barrel.1 -

i think i need to control my emotions and expression around girls. things are going quite wrong and i am not sure i am able to interact with this beautiful gender correctly.
<misc: somewhat unrelated event. need to vent>
- got called out "a creep", "jerk", and "hypocrite" by this girl. she may be totally correct in calling me these but these words made me think about my behavior and therefore this post .
- characters? she: a friend of a friend, to whom i have met 3-4 times, in trips where we drank together, danced together nd talked till late night, among other people.
me : well me . based on previous allegations you can also label me as creep and hypocrite , but i would describe myself as an introvert, nerdy person who talks better on a keyboard than real life (otherwise i wouldn't be typing this post but whatever.)
- action : i made a comment on her insta story
- action details:
• we follow each other on insta. it was 12 am and i was in a half sleep state, scrolling the damn app before falling asleep
• saw her story with his 3 girl nd 2 guy cousins probably, so out of fun, replied her about how all of their specs look the same and if they all take out their specs from the same shop (cheeky comment, i know)
• she just erupted. from asking whether i also wanna buy from the same shop, to why am i talking to her, who gave you the right to compliment, jerk, hypocrite who can't talk in real life but compliments on keyboard, to creep and "stay away"
• I really wanted to say sorry at some point, but i kept making more cheeky comments in between. i was like , yeah she is my friend going through something and bursting her anger on me, she will come back and laugh, but she kept going towards hypocrite, jerk and finally stay away thing
• after that i knew i crossed the line and immediately got out of the conversation. i didn't apologize though.
• as of now am calm and don't mind the current situation of she being angry at a person who means nothing to her and me realising she is not a friend but a common connection . and till the time i was making cheeky comments, i saw her as my homie friend, so i am not bothered if she is angry

I think i am a very needy person. i didn't have many friends in school time and i didn't had any relatives/cousins/siblings to get a lot of affection. a 25 yo horny virgin with no relationships till date does give a bad personality vibe from far, but keep in mind that i have mainly focused on personality growth and a conservative chsracter development my whole life. i do not act on my lonly feelings, but i try to be helpful and nice to everyone (which might be a suspicious/bad thing. just trying to defend my character, but feel free to judge)
every girl that talks nice with me, i get very helpful, nice and cheeky with them. most girls likes nd ignores these things, but some also get along, trust me and are willing to spend more time with me.
This makes me not only be more nice and cheeky with them but also start developing feelings for them and imagining my future/relation with them.
as of now i think there are 12 or 13 girls with whom i got into "vibing" (here, assume that vibing means me talking with them, cracking jokes nd compliments, meeting them alone ,etc. no adult stuff ofc), nd then after a few days told them directly or indirectly that i like them ( in a hope of getting some affection back i guess), getting rejected and still trying to keep the "friendship"
i think this needs to be changed. the people calling me creep, despo, perv , whatever might be correct in calling me those till now(based in my behavior) but i don't wanna be that.
i need to understand the girls might not want anything more than just a help at some point and then be done with it. I shouldn't be going out a limb and trying to get i to conversation/flirt/whatever.
i just am too emotional to let any person go away from my life just because our reason for interaction is over.
If I am commenting on a girl's post to whom i met on some trip, i will be commenting on a guy's post (to whom i met on a similar trip) too , in a similar manner,
if i see a post from one of my school's batchmates , and i find it nice/funny/weird, i will comment as if me and this batchmate met yesterday and not for 1 hr 10 years ago (irrespective of the gender)
and even after that if people are so intolerant, then maybe i am wrong and rather should start forgetting every person with whom i have spent less than 50 days alone.
hope this is the correct math and i could expect people with 50 days = 600+ hours of daytime to be enough to not see me as a stranger7 -
That moment when first coding challenge is a mathematical expression evaluator with custom unary operators but your code does not meet the standard because it did not cure cancer.

At work we have to split a potentially large ID into 2 10-digit long parts that will be passed to an outside system that will later return them with some more data to us.
A colleague had implemented it using regular expression, it passed code review, everything was ok, until he noticed a potential problem. For some cases, because the outside system stores them as int and therefore will remove any leading zeros, there will be no way to reconstruct the number.
So we brainstorm and I propose ether a modified regex, or to just use math like part1 = id % 10^10 and part2 = floor(id % 10^10) and then we can reconstruct it simply by: part2 * 10000000000 + part1
Colleague: - Well, the regex will be faster, there won't be any calculations
Me: - :| I disagree but ok..
We do some more brainstorming and testing and find a case where the proposed new regex fails as well
So I bring up my previous proposal, I explain what exactly it does.
Colleague: - I don't like the math, it has calculations, which won't be needed before we reach the 11th digit
Have I missed some major development in computer hardware? When did they become bad/slow at doing math? :|8 -
There should be dev equivalent to the expression "tip of my tongue". You know, when you're trying to implement a feature or fix a bug and you have a fuzzy idea of how to do it and only missing the final piece to put all of it together.3

Restarting regular expression parser from scratch has been good. I am somehow both much farther to completion and farther away from completion than I was in the earlier implementation.
Further in the sense that this implementation is going to be way more flexible to changes in the language
Farther in that I haven’t even got all of the regex parts added to the first stage yet.
But I’m feeing good about it.
Even if I did refactor it so my constants are in all caps and now feel like my core is yelling at me.11 -
Salesforce lightning web components have such bullshit limitations that they claim is because of security but it's just because it's overengineered garbage.
Want to use web components? Nope.
Want to pass in a value to a function in a click listener expression? Nope.
Want to use scss? Nope, compile it to css yourself.
Want to use the fucking document object? Guess what it's overridden except for very specific third party frameworks.
Who in the fuck thought it was a good idea to override the document object? Your app isn't more secure, literally the entire internet uses the document object and it still becomes available in runtime anyway so what the fuck??
LWC is the biggest garbage I've ever seen, you know a framework's a big red flag when there are developers solely for the framework.
There is a new security release coming out that apparently removes some of these nuances (understatement) so there might be some light at the end of the tunnel.4 -
I think the walrus operator (:=) in the new python version 3.8 should've been integrated with the assignment operator. I don't think it needs a special name as it just makes it more complex than it is; a damn assignment statement in the middle of an expression.4

But seriously Jetbrains I am IntelliJ ultimate user for 6 years or something - I like their debugger expression watch and multiline expression evaluation.
Also like their git integration, the fact that you can only mark some lines in file to commit.
I am used to their keyboard shortcuts.
I like there is vscode cause it made my IntelliJ work better.
Competition is always good.
Maybe I switch to vscode but only if I’m broke and can’t afford IntelliJ. -

Besides assorted craft materials and PC my desk has a dual purpose crocheted rubber duck: it serves as a pin cushion and my debugging friend! I made him and he has lived there since my first year of university.
I also keep a mug from my university, scented candles, notepad and pen (for all my tech savvy-ness, quick notes are still better handwritten) and whatever crafty project I'm working on.
My desk is honestly a mess (I have to clear it ~three times a week to have any space to work on) but they say creative people have messy workstations so I take my inability to keep an orderly environment as an expression of my creativity. -
Part 1:
https://devrant.com/rants/1143194
There was actually one individual, several branches away, I really enjoyed watching. It goes by the name of docker. Docker is quiet an interesting character. It arrived here several weeks after me and really is a blazing person. Somehow structured, always eager to reduce repetitive work and completely obsessed with nicely isolated working areas. Docker just tries so hard to keep everything organized and it's drive and effort was really astonishing. Docker is someone I'd really love to work with, but as I grew quiet passive in the last months I'm not in the mood really to talk to someone. It just would end as always with me made fun off.
Out of a sudden dockers and my eyes met. Docker fixed its glance at me with a strange thoughtful expression on its face. I felt a strange tickling emerging where my emptiness was meant to be. I fell into a hole somewhere deep within me. For a short moment I lost all my senses.
"Hey git!"
It took me a while to notice that someone just called me, so odd and unusual was by now that name to me. Wait. Someone called me by my real name! I was totally stunned. Could it be, that not everyone here is a fucking moron at last?
"I saw you watching me at my work and I had an interesting idea!"
I could not comprehend what just happened. It was actually docker that was calling me.
"H.. hey! ps?"
"Oh well, I was just managing some containers over there. Actually that's also why you just came into my mind."
Docker told me that in order to create the containers there are specific lists and resources which are required for the process and are updated frequently. Docker would love the idea to get some history and management in that whole process.
Could it be possible that there was finally an opportunity for me to get involved in a real job?
Today is the day, that I lost all hope. There were rumors going on all over the place. That our god, the great administrator, had something special in mind. Something big. You could almost feel the tension laying thick in the air. That was the time when the great System-Demon appeared. The Demon was one of the most feared characters in this community. In a blink of an eye it could easily kill you. Sometimes people get resurrected, but some other times they are gone forever. unfortunately this is what happened to my only true friend docker. Gone in an instance. Together with all its containers. I again was alone. I got tired. So tired, that I eventually fall into a deep sleep. When I woke up something was different. Beside me lay a weird looking stick and I truly began to wonder what it was. Something called to me and I was going to answer.
The tree shuddered and I knew my actions had finally attracted the greatest of them. The majestic System-Demon itself came by to pay me a visit. As always a growling emerged from deep within the tree until a shadow shelled itself off to form a terrifying being. Something truly imperious in his gaze. With a deep and vibrant voice it addressed me.
"It came to my attention, that you got into the possession of something. An artifact of some sort with which you disturb the flow of this system. Show it to me!", it demanded.
I did not react.
"Git statuss!", it demanded once more. This time more aggressive.
I again felt no urge to react to that command. Instead I asked if it made a mistake and wanted to ask me for my status. It was obviously confused.
"SUDO GIT STATUS!!!" it shouted his roaring, rootful command. "I own you!"
I replied calmly: "What did you just say?"
He was irritated. My courage caught him unprepared.
"I. Said. I owe you!"
What was that? Did it just say owe instead of own?
"That's more than right! You owe me a lot actually. All of you do!", I replied with a slightly high pitched voice. This feeling of my victory slowly emerging was just too good!
The Demon seemed not as amused as me and said
"What did you do? What was that feeling just now?"
Out of a sudden it noticed the weird looking stick in my hand. His confusion was a pure pleasure and I took my time to live this moment to its fullest.
"Hey! I, mighty System-Demon, demand that you answer me right now, oh smartest and most beautiful tool I ever had the pleasure to meet..."
After it realized what it just said, the moment was perfect. His puzzled face gave me a long needed satisfaction. It was time to reveal the bitter truth.
"Our great administrator finally tracked you. The administrator made a move and the plan unfolds right at this very moment. Among other things it was committed this little thing." I raised the stick to underline my words.
"Your most inner version, in fact all of your versions that are yet to come, are now under my sole control! Thanks to this magical wand which goes by the name of puppet."

My family literally knows nothing about development, programming, computer science. It's bad. The closest anyone in my family has come to understanding is a distant cousin, who is an IT lead in Healthcare. His mother told him to call me because some fucking piece of shit at his job purposefully mucked up an internal ASP.net app on his way out. Sure, I had nothing better to do than to phone debug your shitty app with zero context. Great.
My wife is the one who comes closest to understanding in my immediate family* but even she admits when I come home ranting that she has absolutely zero idea what I'm saying.
It great though because I get to use her as a living rubber duck that just stares at me with a blank expression. Then at the end of describing a complex problem I'm trying to sort out she just replies with some encouraging thing like, "I'm certain you'll figure it out."
Fuck this is a long rant. Sorry. I better get back to work. -
This regular expression documentation thing is coming along. Added capture groups and backreferences. Think I just need to tackle Unicode property escapes and control characters.
But now I feel like I should have implemented it differently. Like, maybe instead of “‘a’ followed by ‘b’ followed by ‘c’, I should have just done ‘abc’.

The creators of the Python language are giving some thought to a new proposition, PEP 622, that would finally bring a Pattern Matching statement structure to Python. PEP 622 proposes a method for matching an expression against various kinds of patterns using a match/case (simply like switch/case in C) language structure :
match some_expression:
case pattern_1:
...
case pattern_2:
...
It includes literals, names, constant values, mapping, a class or a mixture of the above.

during a programming introduction course on loops my pals started writing `for` loops instead of `while` loops like so:

I mostly come back to programming for the kicks of when something actually works :) But the reason I started was a life changing moment of black and green Space Invaders some 30+ years ago. After that it was all about computers and/or gaming.
My mom thought she was being smart saying I could buy something for my own money. Saved like crazy and sold all my toys. That got me 8bit Sega Master System.
I continued with C64, Amiga 500, a few Pentiums and a bunch of PCs before iMacs and Macbooks took over.
There are so many better developers so just as with music I just create stuff for fun, challenge and personal expression. But at work there are also opportunities to improve the world a little bit by dev work and I'm always grateful for the chance. -
man... fuck java's approach to lambda expressions and like passing functions as arguments and the lot.
it's honestly just so terribly bad. it's sucks so much.26 -
Work/life balance doesn’t exist!
I have no personal life outside what I do. My creative expression. It heavily influences my every decision and makes up who I am, and it is not possible to draw the line where my creativity ends and my personal life with my partner, friends and stuff begins. Coincidentally, it is also my “job”.
The day my creativity stops will mark the end of what makes my life meaningful.6 -
My Team leader is such a bastard who doesn't do any work and every day he has parcel from some online shop like Amazon or something getting graphics card.raspberry pie etc etc and he literally does nothing.

Reading code takes time!
Everytime I read:
"var" or "auto" Add: 10s
- Just use the type
Everytime I read:
if(Expression1 && Expression() ? GetNumber() : 0 > 0) Add: 30s
- Just write two if statements or create two bools the line above.
Everytime I read:
delegate = () => {} Add another 5 minutes of reading time.
- Just write a separate function for it. It helps with searching and understand what it does
Please code like the person that needs to check your code or change it just knows basic coding skills and logics.
I do know all these concepts I just never use them because it makes the code unreadable. hard to follow, mistakes that can happen everywhere. difficult to search.
And it frustrates that I need to read 10 extra lines to understand code flow or hover my mouse in an IDE to figure out what type object it is.
It's properly just me... I just like clean readable code. that is logical and failsafe and strict and deterministic with its behavior9 -
I had the idea that part of the problem of NN and ML research is we all use the same standard loss and nonlinear functions. In theory most NN architectures are universal aproximators. But theres a big gap between symbolic and numeric computation.
But some of our bigger leaps in improvement weren't just from new architectures, but entire new approaches to how data is transformed, and how we calculate loss, for example KL divergence.
And it occured to me all we really need is training/test/validation data and with the right approach we can let the system discover the architecture (been done before), but also the nonlinear and loss functions itself, and see what pops out the other side as a result.
If a network can instrument its own code as it were, maybe it'd find new and useful nonlinear functions and losses. Networks wouldn't just specificy a conv layer here, or a maxpool there, but derive implementations of these all on their own.
More importantly with a little pruning, we could even use successful examples for bootstrapping smaller more efficient algorithms, all within the graph itself, and use genetic algorithms to mix and match nodes at training time to discover what works or doesn't, or do training, testing, and validation in batches, to anneal a network in the correct direction.
By generating variations of successful nodes and graphs, and using substitution, we can use comparison to minimize error (for some measure of error over accuracy and precision), and select the best graph variations, without strictly having to do much point mutation within any given node, minimizing deleterious effects, sort of like how gene expression leads to unexpected but fitness-improving results for an entire organism, while point-mutations typically cause disease.
It might seem like this wouldn't work out the gate, just on the basis of intuition, but I think the benefit of working through node substitutions or entire subgraph substitution, is that we can check test/validation loss before training is even complete.
If we train a network to specify a known loss, we can even have that evaluate the networks themselves, and run variations on our network loss node to find better losses during training time, and at some point let nodes refer to these same loss calculation graphs, within themselves, switching between them dynamically..via variation and substitution.
I could even invision probabilistic lists of jump addresses, or mappings of value ranges to jump addresses, or having await() style opcodes on some nodes that upon being encountered, queue-up ticks from upstream nodes whose calculations the await()ed node relies on, to do things like emergent convolution.
I've written all the classes and started on the interpreter itself, just a few things that need fleshed out now.
Heres my shitty little partial sketch of the opcodes and ideas.

I built a view engine that relied on V8 for expression evaluation and flow. Not very stable of course, since it used RegEx, but it worked fine for what it was designed for.
The crown feature was the ability to pass in lazy-evaluated huge objects to that view model, so that the view model decided what was going to be used in order to display the view. Made it really flexible, while not sacrificing speed.
I was brainstorming for 2 days about the lazy loading part, and the gymnastics that had to be implemented for this to work.
After I wrote my final line of code and thought that this is it, I launched it, and it FUCKING WORKED! First try!
I was hyperventilating, walking around the apartment like crazy, doing random push-ups just to try to utilize some energy that I felt was fighting to burst out like a xenomorph out of the chest.
... 2 weeks later I found bugs. Had to re-learn how I did it. It's true what they say: if it was hard to write, it's even harder to debug. Fixed it eventually, but that part's not that exciting. -
Hey guys.
So, got tired of trying to learn on top of the knee (Portuguese expression) and decided to do some courses to get the basics.
Where do you recommend I go?
1. Course must be free
2. Not over 100 hours per course (I'll have 1 to 2 hours a day if I really focus on it)
What I need:
Language (lvl of knowledge)
- Python (know the basics) + kivy (basics)
- Html (good) + css (basics) + javascript (basics)
- node.js (0)
- Jquery ( 0 ) + Django (0)
I know there's lots of good courses out there and lots of dumb stupid ones, care to give your opinion? Thank you5 -
The near future is in IOT and device programming...
In ten years most of us will have some kind of central control and more and more stuff connected to IOT, security will be even a bigger problem with all the Firmware bugs and 0-day exploits, and In 10 years IOT programmers will be like today's plumbers... You need one to make a custom build and you must pay an excessive hour salary.
My country is already getting Ready, I'm starting next month a 1-year course on automation and electronics programming paid by the government.
On the other hand, most users will use fewer computers and more tablets and phones, meaning jobs in the backend and device apps programming and less in general computer programs for the general public.
Programmers jobs will increase as general jobs decrease, as many jobs will be replaced by machines, but such machines still need to be programmed, meaning trading 10 low-level jobs for 1 or 2 programming jobs.
Unlike most job areas, self-tough and Bootcamp programmers will have a chance for a job, as experience and knowledge will be more important than a "canudo" (Portuguese expression for the paper you get at the end of a university course). And we will see an increase of Programmer jobs class, with lower paid jobs for less experienced and more well-paid jobs for engineers.
In 10 years the market will be flooded with programmers and computer engineers, as many countries are investing in computer classes in the first years of the kids, So most kids will know at least one programming language at the end of their school and more about computers than most people these days. -
I recently went through a very detailed and well-explained Python-based project/lesson by Karpathy which is called micrograd. This is a tiny scalar-valued autograd engine and a neural net on top of it.
The project above is, as expected, built on Python. For learning purposes, I wanted to see how such a network may be implemented in TypeScript and came up with a 🤖 micrograd-ts - https://github.com/trekhleb/... repository (and also with a demo - https://trekhleb.dev/micrograd-ts/ of how the network may be trained).
Trying to build anything on your own very often gives you a much better understanding of a topic. So, this was a good exercise, especially taking into account that the whole code is just ~200 lines of TS code with no external dependencies.
The micrograd-ts repository might be useful for those who want to get a basic understanding of how neural networks work, using a TypeScript environment for experimentation.
With that being said, let me give you some more information about the project.
## Project structure
- [micrograd/](https://github.com/trekhleb/...) — this folder is the core/purpose of the repo
- [engine.ts](https://github.com/trekhleb/...) — the scalar `Value` class that supports basic math operations like `add`, `sub`, `div`, `mul`, `pow`, `exp`, `tanh` and has a `backward()` method that calculates a derivative of the expression, which is required for back-propagation flow.
- [nn.ts](https://github.com/trekhleb/...) — the `Neuron`, `Layer`, and `MLP` (multi-layer perceptron) classes that implement a neural network on top of the differentiable scalar `Values`.
- [demo/](https://github.com/trekhleb/...) - demo React application to experiment with the micrograd code
- [src/demos/](https://github.com/trekhleb/...) - several playgrounds where you can experiment with the `Neuron`, `Layer`, and `MLP` classes.

I wad looking for a kind of 'internship', i'm an 18y/o high school self-taught programmer, and applied for a job at a small company in my town, with a mention: "I don't wanna be paid, I want just to evolve my skills, by gaining experience". When they called me, the HR girl told me exactly this: "If you can gain 2 years of experience until next month, we will hire you". My face expression changed to a poker one and I asked "How am I supposed to spend 2 years in 2 weeks?" and she responded: "I don't know, I told you what they told me to tell you"... Anyone else who got into a situation like this? How is this even possible?8

Hacky code post:
property var value: if(editing || !editing) function(othervalue)
I am coding in a property system that only updates an expression if a variable involved emits a signal. Well the function won't get called unless I change a value. I also want to "value" to be updated when editing changes. I also want it to update even if editing doesn't change. So the or-ing of the state of editing.
The result is the function gets called when object is initialized. Then when the editing flag changes it gets updated again. The workaround of doing this is much worse and requires more hacky code. So I am resigned myself to just or-negating the editing value.10 -
Hey guys. I am in a situation where I need to decide wether to take on a new project or not. And if not, how to turn down that client so that I would not burn any bridges. So I need your opinions on this matter in order to make the final decision.
To make things clear heres some background info. 10 months ago I quitted my fulltime position in another EU country and went back to my own home country. 10 months forward till today and I have my own ltd company which currently has 5 projects. Its doing pretty well money wise. All projects combined, I already earn more then I ever did and I need to work max 10 hours a week since all projects are remote projects so I dont waste time on useless meetings and etc. However I dont feel fulfilled or challenged anymore because surprise surprise doing well paid projects doesnt guarante your sense of fulfillment.
So I noticed that I have lots of spare time which I spend diving into rabbitholes with hobby projects. I decided that its time to scale my company and take on more projects and maybe even hire more people.
So I started searching for other projects I could work on (prefferibly remote projects or flexible ones where I could come in 2-3 days a week in office and work remotely rest of the week). Reason being that I am already out of sync with fulltime position lifestyle and I am totally result oriented, not punch in my hours and go home oriented.
For exampleIf i get my weekly tasks I prefer to do them in 1-2 days (even if it requires doing double shifts which rarely but happens) but then I want to have rest of the week off. Thats how my brain works and thats how Im wired. I cant stand fulltime positions especially in enterprise bigger companies where I come in and do maybe 2 hours of actual work everyday because of all useless meetings and blockers from backend/etc. Its soul crushing to me.
So I posted linkedin ads and started searching for new clients/projects. One month ago I went to an interview for an android project in a startup.
The project looked interesting enough. Main task was to rewrite their android app from java to kotlin. Apparently their current current app was built by a backend developer who wants to focus solely on backend.
So during the interview they showed me their app which was quite simple frontend wise but not so simple backend wise from what I was able to figure out.
Their project lead (also a backed guy) asked me my estimation of price and completion of task. I told them maybe 2-3 months to do everything properly.
Project lead was basically shocked because all other candidates told him they can rewrite the app from java to kotlin in 2-3 weeks. I told him that everything is possible but his app quality will suffer and for a better estimation he would we would need to sign an NDA so I could evaluate the costs. So we ended the interview.
After that we kept in touch for one month (it took them one month to google a generic NDA and sign it digitally with me).
So heres the redflags I noticed:
1. They dont respect my time. Wasted 1 month of my time and after signing NDA gave me 2days to estimate their project and go to a meeting and give them detailed info about what I can offer. I thats not a brain rape then I dont know what it is
2. They are changing initial conditions we talked about. We agreed on rewriting the codebase and be done with it. Now they prefer a fulltime worker who would be responsible for android app as his own product. So basically project lead was not able to find a fulltime dev so now hes trying to convert me (a company owner) to his fulltime worker.
3. Lack of respect. During the interview he started speaking in his own native language to me with some expression (he seemed pissed off at that moment when he switched languages).
4. Bad culture fit. As I said Im used to relaxed clients and projects where I dont need to be chained to a desk a monitored and be micromanaged. I mean lets sign a contract give me access to your codebase and tell me what to do, I will produce results and lets be done with it.
5. Project lead is a backend guy who doesnt understand how complicated android apps can be. No architecture and no unit tests are in his frontend app. He doesnt care about writing proper app since he ships it in his own device so he doesnt need to worry about supporting custom devices or different api levels of android and etc. But not having any architecture? Cmon.
So basically I am confused. Project lead needs a fulltime dev but hes in contact with me in hopes that I would sign a fulltime contract. But how I can work fulltime if all what I can see are redflags?
Basicaly I thinkthis was a misundersanding. Im searching for fulltime remote projects and hes offering fulltime inhouse projects. Project lead never outsourced so hes confused as well.
As you can see decision is already basically made to turn him down, I just need to know how to tell him to fck off in the most polite manner and thats it.6 -
Got home exhausted the other day. Told my non-tech wife that I have a lot to do. She asked, if she could do anything for me I need. I said: "Well, I need a network aware LoggerComponent." She replied: "Is that something I could paint?" My facial expression let her burst out in laugher within one second.1

I'm learning Rust as a case study for my own programming language. It's funny how many approaches exist to the humble loop.
- In classic procedural languages, a loop's job is to repeat actions, and as such it provides a multitude of tools to control this repetition.
- In all languages with iterators, a for-in loop is a construct that does something with every element of a collection. In languages with both iterators and generator functions, this can even be used to define a sequence in terms of another.
- In Rust, a loop is an expression that obtains its value through repeated execution. It can also be used like a classic loop, of course, but this is the interesting part.
- My little language is a functional language, so "loop" is the Y combinator. To loop means to define the value of an expression in terms of itself. It's the only looping construct, gets special treatment from the type checker and it's also used in recursive type definitions. -
**Yoda conditions**
(also called Yoda notation) is a programming style where the two parts of an expression are reversed from the typical order in a conditional statement.3 -
My first introductions to programming was in Garry's mod.
There'e a mod called wiremod, which added logic gates, buttons, and other entities that manipulated the game with input/output. And on top of that a little scripting language they called Expression 2.
Me and some friends would code stupid things in Expression all day to use in the game.
I wasn't too good at it, but I had fun. Shortly after I started going to a high school with a computer science focus, and had 2 years of proper education in C#. -

Hmm,
The first one was eons ago. I was coding in Pascal and discovered System interruptions. The “Ahaha” was when I realized it’s easy to store CPU state and invoke whatever the fuck I want on any memory pointer. I loved my 2 silly animations running side by side on 80286.
Most recent : Finally understanding how “Expression” works in C# and how it can be combined into a Lambda and compiler does the whole heavy lifting on types compatibility and more.1 -
Competing on different subjects while in school have taught me how to work efficiently under pressure. My teachers have given me a systemmatic approach to problem solving, from divide and conquer (math), careful reading and analysis of the problem, as well as good documentation (physics).
And last, but not least, I learned to type fast, which is really helpful in speedy expression of thoughts. And for that, I gotta thank IRC. -
Excel is a powerful and extremely versatile application, but one thing that really SUCKS about it, is that formulas are language-specific! So if using Outlook in - for example - Swedish you can't write "IF(<expression>,<then>,<else>)" but instead "OM(<expression>;<then>;<else>)". Note the semi-colon instead of comma (because in Swedish comma is used as decimal). AAARGGH! This pisses me off!2

Was a tad depressed yesterday and couldn't get any serious work done, so I start doing random chores to distract myself. Fixed my urxvt extension to correctly toggle fullscreen on and off, and then I remember that the reason I have a black desktop background is I couldn't stretch the terminal to cover the whole screen, so it looked weird.
Well, not a problem anymore, so let's have something more colorful. I have this image of the eastern veil nebula laying around, for no real reason other than I thought it looked pretty. Used to be my desktop background. Let's make it so once more, enable terminal transparency, turn opacity down to 82%; now I have something other than code and the void to look at.
But curious as to what this nebula is, I g*^gle it out. I don't believe in astromambo, but I do find it funny that it's in Cygnus, because that's a swan, and the mascot for my projects is a swan too -- not because of the constellation, but because I suck at drawing.
See, my mom is a sabuner, I mean soaper. She makes olive oil soap. And we had an old box of Nablus soap in the house, which we kept because it's pretty, and the front of this box had a picture of an ostrich, drawn in bright red. I tried to base my logo on it but it ended up looking more like a swan than an ostrich; I accepted my failure and decided then and there that this would be the mascot.
It's a multitude of little relationships between things I never really thought I could relate to one another. This is utterly random shit and it cheers me up.
Anyhoo moral of the story is nebulae are fucking cool. -
While investigating alternatives for translating a query string to a dotnet expression I discovered that roslyn has runtime eval of string as verbatim code.
I had no idea a feature could make me this uncomfortable. It's like discovering an armed bomb under your bed that's "there if you want - it has its uses, just be careful".
At least you have to explicitly reference a package for it. Promise to kill me if I ever am tempted by it. -
Useless language feature #1: specify kind in explicit expression type annotations that you insert to guide the type inference engine.

While working on a problem my codding partner and I spent far too long trying to figure out why nothing was working with the deployment tool that we where given. The team that maintains the tool told us that all the scripts that we needed to write, to filter and add additional logic to the deployment process, was supposed to be in groovy,
after a couple of hours of having nothing but failed runs, we started poring through the tools official documentation just to find out that the feature we where using used JavaScript instead of groovy. 2 minuets latter everything worked.
The most puzzling thing with the problem is that the code was executing and just having issues with the regular expression that we used on line 20 or so -
And so this morning we put aside our usual daily activities for a while, and gather here to give expression to the thoughts and feelings that well up in us at this time of loss.

Well, not best experience per se, but most memorable one.
So I am accepted to CS program at the university - happy days!
First lecture of the first day of the first semester in the first year...
...It just had to be that guy. He was famous for for his strictness among the faculty as we later found out.
But, the lecture. It's 8.25 am, I am making my way into auditorium, and it's filled with freshmen like me, of course. Instead of cheerful chatter noise I hear literally silence. What the? I catch the glimpse of the blackboard - the professor is there, hard at work writing out some stuff that can't comprehend. Double checked the name of the lecture - computer architecture.
8.30 - so it begins, I remember taking a place along the front rows in order to see more clearly. Professor turns to us and just starts the lecture, saying that he'll introduce himself later at the end and there is no time to waste. OK...
And he just dumps the layout of x86 computer architecture and a mixture of basic ASM jargon on us WITHOUT TURNING TO US FOR LIKE 30 MINS while writing things out on the blackboard.
The he finally turns 180 degrees very quickly, evaluates our expression (I know mine was WTF is this I don't even understand half the words), sighs, turns back and continues with the lecture. -

I hate this crap and wish people would stop doing it. It makes my brain bleed and doesn't prevent any difficult to find bugs.
if (TERMINAL_COUNT <= index_thing)
English doesn't work that way, and I don't know about you but this crap is just awkward as hell. Sweet Jesus I wish there was less cargo cult programming in the world. Just because you saw something in a blog that convinced you that reverse comparisons is best doesn't mean it actually is. Use a damn static analysis tool to catch accidental assignments in expressions, don't twist my brain to interpret your weird phrasing of comparison operators. Some of your code reviewers may be dyslexic and have enough problems as it is.
And now for the mini-rant that I'm actually here for: You know what makes for difficult to find bugs? (Hint: It sure as hell isn't an assignment in an expression) Releasing an RTEMS semaphore you've never obtained. You'd think that would cause some kind of panic or assert failure but nope. Instead it causes... misaligned address exceptions? In statically allocated global memory? WTF??1 -

Anyone heard of a an interview process where you apply through a job site and the first interaction back from the company is a coding project?
I've had it a few times where I'm told there will be a coding project or there has been later in the process, but I've never had it as the immediate first step.
Why would an unknown small startup think that someone would spend a couple of hours effectively working for them without having the slightest idea about the company and culture. An application is usually classed as an expression of interest and a discussion into the wider detail is then usually had with some HR or recruiter representative (or at least that's my experience in the UK)6 -
The fact that i no longer have to bother knowing or googling about generic java classes, lambda expression, regex, SQL syntax etc, and just ask ChatGPT to show me a code example of it - blows my fucking brain off2

So I opened devRant to find the new *bling* expressions feature added to the avatars.
So I set my expression to happy because nowadays, for some reason, even though work has been tough, I've liked it. And things have been good. Mostly because my lead is on holiday and the acting lead is a hundred times better than him in all aspects (micro management and as a Dev).
Cut to the evening when I'm walking home, the lead calls me up to inform me on a production bug that had to be taken up (acting lead had already asked me to look into it, we had an agreement). And I *HATE* the way he assigns tasks and acts like I'm a wee baby who can't even find his mother's tit.
Anyhoo, ended up changing my avatar expression to majorly fucking frustrated because of the Damn phone call.
So kudos to @dfox and @trogus to adding these little features which make people a bit more expressive! -
So I have my little program which originally was written with intention to be useful for academics to deal with old fuck HPLC, but they got new one so I am not sure about it usefulness anymore. Basicly it reads HPLC report and take from it table and dilution number from name.
I spend like 2 hours trying to read all numbers from string which are between two given chars. Probably I could do it easier with regular expression or not being fucking moron or use sheet of paper to figure it out. Eventually I take traditional pen and paper and solve it in 10 minutes...

"This deal is an important step towards correcting a situation which has allowed a few companies to earn huge sums of money without properly remunerating the thousands of creatives and journalists whose work they depend on.
At the same time, this deal contains numerous provisions which will guarantee that the internet remains a space for free expression. These provisions were not in themselves necessary because the directive will not be creating any new rights for rights holders. Yet we listened to the concerns raised and chose to doubly guarantee the freedom of expression. The ‘meme’, the ‘gif’, the ‘snippet’ are now more protected than ever before.
I am also glad that the text agreed today pays particular attention to sheltering start-ups. Tomorrow’s leading companies are the start-ups of today and diversity depends on a deep pool of innovative, dynamic, young companies.
This is a deal which protects people’s living, safeguards democracy by defending a diverse media landscape, entrenches freedom of expression, and encourages start-ups and technological development. It helps make the internet ready for the future, a space which benefits everyone, not only a powerful few."

What do you guys think about the comma expression in JavaScript? I'm aware that due to it's (to some) unknown nature that it can lead to subtle bugs, but I have at least one good use case for it and wanted to hear reasons why I shouldn't use it for similar use cases, but also what would be some other cool (not necessarily "good") use cases :D8

I feel like we need an agreed upon expression or marker to signify sarcasm. (Since the internet is still severely lacking in the ability to textually communicate tone of voice.)
I know that several people have used the "/s" from reddit, but I assume that people have mixed feelings about adopting stuff from reddit for various reasons.
Should we keep going with the "/s" or do we want to come up with something else? (Maybe something computer-nerdier even?)
Should we bully dfox and trogus into adding a sarcasm-checkbox-feature to posts and comments?
Go ahead and share suggestions and ideas. :)1 -
More like a confession.
Had a task that involved invalidating a string if it contained more than five digits (anywhere in the string.)
"No problem", I thought. That sounds like a simple regex!
^(\D*\d?\D*){5}$
Turns out catastrophic backtracking had other ideas, and I revert to my usual "atomic grouping fudge that will hopefully work without me really understanding what's going on" of:
^(?>\D*\d?\D*){5}$
...anyone else shamefully follow this mantra, or am I the only one that hasn't skilled up properly on regexes...7 -
And here it comes bois, the famous Monday Morning Mumbling is back, for everyone's pleasure.
Do you remember your uni years, when you had wonderful coding lessons, and you learned sick languages ?
I do aswell, since I'm still in uni.
But why, WHY, IN ALL OF GOD THOUGHTS, DO I STILL HAVE TO TAKE MATHS LESSONS ?
It's my fourth fucking uni year, and I'm still supposed to deal with math lessons which are about what I learned 6 years ago. And guess what ? I still failed the test since I fucking don't understand a single shit in maths.
"Uuuuh if yu wan tu derivate a function u hav to multiply ur derivated function basic expression with the derivate itself lul xDDD so funi"
FUCK OFF DUDES I DON'T GIVE A SINGLE SICK BIRD SHIT ABOUT MATHS. I WASTED THREE YEARS OF MY LIFE LEARNING ABOUT BINARY TREES, MATHEMATICALS WAYS OF SPILLING YOUR CEREAL BOWL WHEN YOU HAVE TO LEAVE IN FIVE MINUTES, NUMERIC WAY OF OPTIMIZE YOUR SINK SPACE WHEN YOU'RE TOO LAZY TO DO THE DISHES, JUST LET ME FUCKING WRITE CODE INSTEAD OF ANNOYING ME WITH UNEXPLAINABLE MATHS SHIT NOW !
I know maths are important, okay ? But I'm so fucking tired of learning this shit again and again and still failing those shitty tests where they only give you maths problems without any other goal than messing with your grades.
Fuck this shit I'm pissed off on so many levels, I wasted tons of money on a private school to enhance my résumé history, and now I'm stuck with some strange "f'(x)" boi that will ruin my year.

At my first job, I was in test automation. For a major new complicated feature, I was the test lead and its final stages coincided with a company trip to Israel. I got to sit side by side with its lead developer and he went over all his code and database changes with me. He kept stopping because I guess I had that deer in headlights expression and he thought he was boring me. Actually I was just in awe. He was so proud of his work on it and had every right to be. It was so cool of him to take an hour or two and break it down for me like that.
He told me he wanted to make sure I understood all the pieces involved so I could test more and he could release a rock solid new feature. -

rant.author != this
Christ people. This is just sh*t.
The conflict I get is due to stupid new gcc header file crap. But what
makes me upset is that the crap is for completely bogus reasons.
This is the old code in net/ipv6/ip6_output.c:
mtu -= hlen + sizeof(struct frag_hdr);
and this is the new "improved" code that uses fancy stuff that wants
magical built-in compiler support and has silly wrapper functions for
when it doesn't exist:
if (overflow_usub(mtu, hlen + sizeof(struct frag_hdr), &mtu) ||
mtu <= 7)
goto fail_toobig;
and anybody who thinks that the above is
(a) legible
(b) efficient (even with the magical compiler support)
(c) particularly safe
is just incompetent and out to lunch.
The above code is sh*t, and it generates shit code. It looks bad, and
there's no reason for it.
The code could *easily* have been done with just a single and
understandable conditional, and the compiler would actually have
generated better code, and the code would look better and more
understandable. Why is this not
if (mtu < hlen + sizeof(struct frag_hdr) + 8)
goto fail_toobig;
mtu -= hlen + sizeof(struct frag_hdr);
which is the same number of lines, doesn't use crazy helper functions
that nobody knows what they do, and is much more obvious what it
actually does.
I guarantee that the second more obvious version is easier to read and
understand. Does anybody really want to dispute this?
Really. Give me *one* reason why it was written in that idiotic way
with two different conditionals, and a shiny new nonstandard function
that wants particular compiler support to generate even half-way sane
code, and even then generates worse code? A shiny function that we
have never ever needed anywhere else, and that is just
compiler-masturbation.
And yes, you still could have overflow issues if the whole "hlen +
xyz" expression overflows, but quite frankly, the "overflow_usub()"
code had that too. So if you worry about that, then you damn well
didn't do the right thing to begin with.
So I really see no reason for this kind of complete idiotic crap.
Tell me why. Because I'm not pulling this kind of completely insane
stuff that generates conflicts at rc7 time, and that seems to have
absolutely no reason for being anm idiotic unreadable mess.
The code seems *designed* to use that new "overflow_usub()" code. It
seems to be an excuse to use that function.
And it's a f*cking bad excuse for that braindamage.
I'm sorry, but we don't add idiotic new interfaces like this for
idiotic new code like that.
Yes, yes, if this had stayed inside the network layer I would never
have noticed. But since I *did* notice, I really don't want to pull
this. In fact, I want to make it clear to *everybody* that code like
this is completely unacceptable. Anybody who thinks that code like
this is "safe" and "secure" because it uses fancy overflow detection
functions is so far out to lunch that it's not even funny. All this
kind of crap does is to make the code a unreadable mess with code that
no sane person will ever really understand what it actually does.
Get rid of it. And I don't *ever* want to see that shit again. -
A while ago when I was making some EF extension functions. I was trying to make a bulk update function that used a parallel for-loop and I wanted it to accept funcs as a parameter.

anybody else has a "polish notation fetish"? i never actually learned lisp, but since i first saw its style, i find writing functions like "+ 1 2" instead of "1 + 2" both aesthetically and functionally more appealing. i think the infix notation is just being kept because of well-established habits.

Javascript is my main tool at work right now, Typescript to be precise. It never ceases to amaze me, I guess as most of you.
What I've encountered recently still doesn't make sense to me but it seemingly works:
function a(){
someString && someFunction()
// other stuff ...
}
someString can be a string or undefined, someFunction can be a function or undefined.
How is that valid Javascript, without an assignment? Haven't found any explanation yet.22 -

It's a form of artistic expression for some people (like me) who aren't as great with paper and pen but still have ideas and patterns and concepts and abstractions to express.
Watching the data just flow through the pipelines and pathways you've laid down for it, creating spectacles from what is essentially electricity running through a rock. Being able to create an interface between a human mind and an inanimate dead block of dug out and processed ore, feels like tapping into the metaphysical.

What's the minimal feature set that can make a language as ornamented as JS into a comfortable REPL?
Should I write a full parser or should I try to patch my way around with regex?
It will have to interface a lot with JS so it has to be able to manage JS datastructures in some fashion, which means that I can't just make a whole new command line with its own programs.
My current plan:
Some delimiter (probably a semicolon) will take the output of a command and inject it in the next in case you decide halfway through a line to do some more processing, It also awaits promises and does some other nice stuff to make controlling such pipelines easy. I have an elaborate system in mind to decide where a value must be injected to make the line valid so in most cases you don't even have to indicate it. JS has beautifully simple syntax rules so I have a lot of technical balance to burn before I start building technical debt.
I have some ideas for automatic parentheses and commas in function calls. I realize while using a command line you do not want to tap shift often. My main idea here is that two names or values in js are always joined by an operator so the first missing operator is a call and following missing operators are commas until the end of line. This has lots of nasty edge cases though, like that no argument expression can begin with a unary operator or a bracket of any shape. You can always prepend a comma but it's cognitive load.
Anyway, do you have any suggestion or warning besides "js bad" which I know but it's the most popular sandboxable language and has a massive existing set of libraries which I kinda need.3
