Has anyone been paying attention to what Google's been up to? Seriously!

1) Fuchsia. An entire OS built from the ground up to replace Linux and run on thin microcontrollers that Linux would bog down — has GNU compilers & Dart support baked in.

2) Flutter. It's like React Native but with Dart and more components available. Super Alpha, but there's "Flutter Gallery" to see examples.

3) Escher. A GPU-renderer that coincidentally focuses on features that Material UI needs, used with Fuchsia. I can't find screenshots anywhere; unfortunately I tore down my Fuchsia box before trying this out. Be sure to tag me in a screenshot if you get this working!

4) Progressive Web Apps (aka Progress Web APKs). Chrome has an experimental feature to turn Web Apps into hybrid native apps. There's a whole set of documentation for converting and creating apps.

And enough about Google, Microsoft actually had a really cool announcement as well! (hush hush, it's really exciting for once, trust me)...
Qualcomm and Microsoft teamed up to run the full desktop version of Windows 10 on a Snapdragon 820. They go so far as to show off the latest version of x86 dekstop Photoshop with no modifications running with excellent performance. They've announced full support for the upcoming Snapdragon 835, which will be a beast compared to the 820! This is all done by virtualization and interop libraries/runtimes, similar to how Wine runs Windows apps on Linux (but much better compatibility and more runtime complete).

Lastly, (go easy guys, I know how much some of you love Apple) I keep hearing of Apple's top talent going to Tesla. I'm really looking forward to the Tesla Roof and Model 3. It's about time someone pushed for cheap lithium cells for the home (typical AGM just doesn't last) and made panels look attractive!

Tech is exciting, isn't it!?

I'm a self-taught 19-year-old programmer. Coding since 10, dropped out of high-school and got fist job at 15.

In the the early days I was extremely passionate, learning SICP, Algorithms, doing Haskell, C/C++, Rust, Assembly, writing toy compilers/interpreters, tweaking Gentoo/Arch. Even got a lambda tattoo on my arm after learning lambda-calculus and church numerals.

My first job - a company which raised $100,000 on kickstarter. The CEO was a dumb millionaire hippie, who was bored with his money, so he wanted to run a company even though he had no idea what he was doing. He used to talk about how he build our product, even tho he had 0 technical knowledge whatsoever. He was on news a few times which was pretty cringeworthy. The company had only 1 programmer (other than me) who was pretty decent.

We shipped the project, but soon we burned through kickstart money and the sales dried off. Instead of trying to aquire customers (or abandoning the project), boss kept looking for investors, which kept us afloat for an extra year.

Eventually the money dried up, and instead of closing gates, boss decreased our paychecks without our knowledge. He also converted us from full-time employees to "contractors" (also without our knowledge) so he wouldn't have to pay taxes for us. My paycheck decreased by 40% by I still stayed.

One day, I was trying to burn a USB drive, and I did "dd of=/dev/sda" instead of sdb, therefore wiping out our development server. They asked me to stay at company, but I turned in my resignation letter the next day (my highest ever post on reddit was in /r/TIFU).

Next, I found a job at a "finance" company. $50k/year as a 18-year-old. CEO was a good-looking smooth-talker who made few million bucks talking old people into giving him their retirement money.

He claimed he changed his ways, and was now trying to help average folks save money. So far I've been here 8 month and I do not see that happening. He forces me to do sketchy shit, that clearly doesn't have clients best interests in mind.

I am the only developer, and I quickly became a back-end and front-end ninja. 

I switched the company infrastructure from shitty drag+drop website builder, WordPress and shitty Excel macros into a beautiful custom-written python back-end.

Little did I know, this company doesn't need a real programmer. I don't have clear requirements, I get unrealistic deadlines, and boss is too busy to even communicate what he wants from me.

Eventually I sold my soul. I switched parts of it to WordPress, because I was not given enough time to write custom code properly.

For latest project, I switched from using custom React/Material/Sass to using drag+drop TypeForms for surveys.

I used to be an extremist FLOSS Richard Stallman fanboy, but eventually I traded my morals, dreams and ideals for a paycheck. Hey, $50k is not bad, so maybe I shouldn't be complaining? :(

I got addicted to pot for 2 years. Recently I've gotten arrested, and it is honestly one of the best things that ever happened to me. Before I got arrested, I did some freelancing for a mugshot website. In un-related news, my mugshot dissapeared.

I have been sober for 2 month now, and my brain is finally coming back. 

I know average developer hits a wall at around $80k, and then you have to either move into management or have your own business.

After getting sober, I realized that money isn't going to make me happy, and I don't want to manage people. I'm an old-school neck-beard hacker. My true passion is mathematics and physics. I don't want to glue bullshit libraries together. 

I want to write real code, trace kernel bugs, optimize compilers. Albeit, I was boring in the wrong generation.

I've started studying real analysis, brushing up differential equations, and now trying to tackle machine learning and Neural Networks, and understanding the juicy math behind gradient descent.

I don't know what my plan is for the future, but I'll figure it out as long as I have my brain. Maybe I will continue making shitty forms and collect paycheck, while studying mathematics. Maybe I will figure out something else.

But I can't just let my brain rot while chasing money and impressing dumb bosses. If I wait until I get rich to do things I love, my brain will be too far gone at that point. I can't just sell myself out. I'm coming back to my roots.

I still feel like after experiencing industry and pot, I'm a shittier developer than I was at age 15. But my passion is slowly coming back.

Any suggestions from wise ol' neckbeards on how to proceed?

uh oh i did something bad

This facts are killing me

"During his own Google interview, Jeff Dean was asked the implications if P=NP were true. He said, "P = 0 or N = 1." Then, before the interviewer had even finished laughing, Jeff examined Google’s public certificate and wrote the private key on the whiteboard."

"Compilers don't warn Jeff Dean. Jeff Dean warns compilers."

"gcc -O4 emails your code to Jeff Dean for a rewrite."

"When Jeff Dean sends an ethernet frame there are no collisions because the competing frames retreat back up into the buffer memory on their source nic."

"When Jeff Dean has an ergonomic evaluation, it is for the protection of his keyboard."

"When Jeff Dean designs software, he first codes the binary and then writes the source as documentation."

"When Jeff has trouble sleeping, he Mapreduces sheep."

"When Jeff Dean listens to mp3s, he just cats them to /dev/dsp and does the decoding in his head."

"Google search went down for a few hours in 2002, and Jeff Dean started handling queries by hand. Search Quality doubled."

"One day Jeff Dean grabbed his Etch-a-Sketch instead of his laptop on his way out the door. On his way back home to get his real laptop, he programmed the Etch-a-Sketch to play Tetris."

"Jeff Dean once shifted a bit so hard, it ended up on another computer. "

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

Well lemme answer that question for you lot.

YES YOU ARE A BLOODY IMPOSTER.

There. I said it. BUT.

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

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

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

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

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

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

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

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

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

Fun/Interesting fact:
"++i" can be slightly faster than "i++"

Because  "i++" can require a local copy of the value of "i" before it gets incremented, while "++i" never does. In some cases, some compilers will optimize it away if possible... but it's not always possible, and not all compilers do this.

Well, it all started off with hardware-level programming involving jumpers and stuff like that... Then came Assembly, which was good.. B, C compilers. Finally came the interpreted languages, and that's where in my opinion the abstraction should've ended. But no, we needed more frameworks, more libraries, even more abstraction! Where does it end? As it seems to be going, I guess that users will have kid toys - no iToys! - for electronics and we'll be programming on with bloated Scratch GUI's. Nothing against Scratch, but that shit ain't proper programming anymore. God I can't wait for the future.

ABSTRACT ALL THE THINGS!!!

Oh and not to mention that all software will be governed in political correctness by some Alex SJW AI shit that became sentient. Not a single programming term will be non-offensive anymore, no matter how hard you try to not offend anyone, or God forbid - don't care about it because you just want to make something that's readable, usable and working!! Terms, UI names for buttons, heck even icons! REMOVE IT BECAUSE IT OFFENDS SOMEONE THAT I DON'T EVEN KNOW JACK SHIT ABOUT!!!

Sometimes.....

When I want to escape how dull/repetitive/boring the world of web development is. I crack open a nice lil terminal, dust off my gcc/g++ compilers and fuck around in C or C++ till my eyes start to bleed.

I have been fucking around with systems development. Mainly with Linux programming. I have also started to get deeper on game engine design and compiler design....because low level development is where its at.

A man can only fuck around rest apis, css and html and the endless sea of Javascript and other dynamic languages for so long before going crazy.

Eventually.....I would want to code something impressive enough to give me a spot somewhere as a C or C++ developer. I just can't work with web development any longer man. It really is not what I want to do, the fact that I do it(and that I am good at it) is circumstantial more than because I really enjoy it. I really don't

Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.

Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)

Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.

Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.

Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.

Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.

Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)

When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.

Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)

Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)

And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?

Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.

For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)

Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.

Teach them advanced google searches.

Teach them how to write a issue for a library on GitHub and similar sites.

Teach them how to ask a good stackoverflow question :>

Sometimes I feel like a freak. So many rants are about things that just never seen to happen to me.
I've been using Windows 10 since release, never had an update while I was working.
I've never gotten a virus from an ad, abs don't use AdBlock.
I've never had a crash that lost my work, I save neurotically or the program automatically saved.
I've never had trouble with typing in any language, static or dynamic.
I've never had issues with semicolons, IDEs or compilers tell me the issue explicitly.
I guess I'm just weird or something :/

Compilers should automatically show devRant feed while compiling

I love when compilers give good, clear feedback.

Dynamically typed languages are barbaric to me.

It's pretty much universally understood that programmers program with types in mind (if you have a method that takes a name, it's a string. You don't want a name that's an integer).

Even it you don't like the verbosity of type annotations, that's fine. It adds maybe seconds of time to type, which is neglible in my opinion, but it's a discussion to be had.

If that's the case, use Crystal. It's statically typed, and no type annotations are required (it looks nearly identical to Ruby).

So many errors are fixed by static typing and compilers. I know a person who migrated most of the Python std library to Haskell and found typing errors in it. *In their standard library*. If the developers of Python can't be trusted to avoid simple typing errors with all their unit tests, how can anyone?

Plus, even if unit testing universally guarded against typing errors, why would you prefer that? It takes far less time to add a type annotation (and even less time to write nothing in Crystal), and you get the benefit of knowing types at compile time.

I've had some super weird type experiences in Ruby. You can mock out the return of the type check to be what you want. I've been unit testing in Ruby before, tried mocking a method on a type, didn't work as I expected. Checked the type, it lines up.

Turns out, nested away in some obscure place was a factory that was generating types and masking them as different types because we figured "since it responds to all the same methods, it's practically the same type right?", but not in the unit test. Took 45 minutes on my time when it could've taken ~0 seconds in a statically typed language.

Code review time:

Hey Rudy, can you approve my PR? ??? Shouldn't it be can you review my PR?(thought to myself)
Anyway, as a new practice, we(royal we) do not approve PRs with js files. If we touch one, we convert it to typescript as part of a ramp up to a migration that never seems to get here. But I digress.
I look at the laziest conversion in history.

Looked like
Import 'something';
Import 'somethingElse';
Import 'anotherSomething';

export class SomeClass {
public prop1: any;
public prop2: any;
public prop3: any;

public doWork(param: any){
let someValue = param;
// you get the idea
return someValue;
}
}

Anyway, I question if all the properties need to be visible outside of the class since everything was public.
Then if the dev could go and use type safety.
Then asked why not define the return type for the method since it would make it easier for others to consume.
Since parts of the app are still in js, I asked that they check that that the value passed in was valid(no compilation error, obviously).
Also to use = () => {} to make sure "this" is really this.
I also pointed out the import problem, but anyway.

I then see the his team leader approve the PR and then tell me that I'm being too hard on his devs. ????

Do we need to finish every PR comment with "pretty please" now?
These are grown men and women, and yet, it feels oddly like kindergarten.

I've written code in the past that wasn't pretty and I received "WTF?" as a PR comment. I then realized I ate sh*t on that line of code, corrected it and pushed the code. Then we went to Starbucks.
I'm not that old(35), but these young devs need to learn that COMPILERS DO NOT CARE ABOUT YOUR FEELINGS!!!!!
Ahhhhhh
Much better.
Thanks for the platform.

Knock knock!

Who's there?

(after sixty seconds)

Java program.

Nobody writes compilers anymore. :(

To the people that create compilers.
Is it so goddam hard to tell me which fucking object is Null?

Most kids just want to code. So they see "Computer Science" and think "How to be a hacker in 6 weeks". Then they face some super simple algebra and freak out, eventually flunking out with the excuse that "uni only presents overtly theoretical shit nobody ever uses in real life".

They could hardly be more wrong, of course. Ignore calculus and complexity theory and you will max out on efficiency soon enough. Skip operating systems, compilers and language theory and you can only ever aspire to be a script kiddie.
You can't become a "data scientist" without statistics. And you can never grow to be even a mediocre one without solid basic research and physics training.

Hack, I've optimized literal millions of dollars out of cloud expenses by choosing the best processors for my stack, and weeks later got myself schooled (on devRant, of all places!) over my ignorance of their inner workings. And I have a MSc degree. Learning never stops.

So, to improve CS experience in uni? Tear down students expectations, and boil out the "I just wanna code!" kiddies to boot camps. Some of them will be back to learn the science. The rest will peak at age 33.

If first compiler was compiled by humans, now compilers are compiled using compilers. Then the first chicken didn't come from egg, but something superior. Nowadays we just see eggs turning into chicken, but the origins of chickens isn't related to eggs at all.
#Computer engineering

wanna talk about compilers?

Why is starting a C++ project so overly complicated and annoying?!

So many different compilers. So many ways to organize the files. So many inconsistencies between Linux and Windows. So many outdated/lacking tutorials. So many small problems.

Why is there almost no good C++ IDEs? Why is Visual Studio so bizarre? Why are the CMake official tutorials literally wrong? Why can't we have a standard way to share binaries? Why can't we have a standard way to structure project folders? Why is the linker so annoying to use?

Don't get me wrong, I quite like the language and I love how fast it is (one of the main reasons I decided to use it for my project, which is a game almost comparable to Factorio)... But why is simply starting to write code such a hassle?

I've been programming in Java for years and oh god I miss it so much. JARs are amazing. Packages are amazing. The JDK is amazing. Everything is standardized, even variable names.

I'm so tempted to make this game in Java...

But I can't. I would have a garbage collector in the way of its performance...

A couple days ago, I went through the most embarrassing interview ever. It was a startup into both hardware and software merged over image processing. I really wanted it. Really really did. It was telephonic, and involved a little bit coding over docs. In the one hour we talked over the phone, he asked me about 30 questions. I hadn't even heard of the words he said! Ive never delved into compilers, lower level things, and memory management. I could answer about 5 questions- including the tell me about yourself question.

So thats about 25 ways I came up with of saying "I don't know" in a span of 60 minutes.

Worst things about being a dev? Boy, this will be a long one!
- Whatever I do, be it hard work or smart work, I feel I am always underpaid.

- Most people who don't know tech feel my job shouldn't take that long. "Oh, a website that should be easy." "Oh, REST services, that's cute!"

- Most people who know a little tech will be like, "Here is the code for this on Google, then why are you charging this much"

- Companies like Microsoft and Apple who are too cool to follow standards.

- Always underpaid!

- The friggin compilers and random environment vars. Sometimes you make no change and the code works on a restart. I mean wtf!

- Having to give/meet deadlines, when we know most of the times things get out of control.

- Having to work for jerks mostly who don't know squat, and can't tell the difference between a CPU and a Wooden box.

- Sometimes I wanna take a break from my laptop(traveling and stuff) , those are the times I get the maximum work load!

- Did I mention we are always underpaid?

- Because of the kind of work I do, finding a girl has been challenging. Where the heck are they!

- We have to stay always updated. Often we deploy something using a framework and the next day we see an update.

- Speaking of updates, I hate having to support for OSes like Microsoft.

- Speaking of OSes, I hate Apple!

- Speaking of Apple, I feel we are underpaid, de javu?
...
How much would you hate me if I wrote "just kidding" ?

Ok, so teacher (which should be something like a professional dev or whatever) assigned us a homework for a Christmas (I dont care, I can complete his assignments in like 10 minutes max). We have to do some simple shit in C++, just some loops and input + output. Nothing hard. He challenged me to write it as short as possible, so I did. My classmates have codes around 60 to 70 lines long (after propper formating). I made it 20 lines long using some pointer magic and stuff like that. I tried my code, it ran fucking perfectly, so I sent that to him. He replied that the code does not work. I tried to recompile it and it ran perfectly. Again, it does not work. Afeter 13 fucking emails he fucking finally sent me the error message. Some fucntion was not found (missing some library but literally everywhere else it works without it...). Thats strange, because it run perfectly on my Fedora with CLion, so I switch to Windows and try to run same code in Visual Studio (which we are using in school btw). Works perfectly. So I start arguing with the teacher more and more. I tried around 10 online compilers. Works fuckng everywhere. Teacher is pissed, me too. So I rewrote my whole code, added comments and shit, reinvented wheel literally everywhere. Now I have C99 standardised code over 370 lines long that run even on a fucking arduino after changing input output methods so it can work with it. It (suprisingly runs) on his PC too.

After a bit more arguing, he said that he is using CodeBlocks from fucking 2015. Wow. Just fucking wow. Even our school has some old Visual Studio (2007 I guess) and it worked there.

Currently I'm working on 3D game engine and making a 3D minesweeper game with it.
I have started creating a compiler not long ago using my own implementation (no Lex no tools nothing just raw algorithms application) to hopefully some day I will be able to make a language that works on top of glsl inside my game engine. I have compilers design class this semester which haven't even started yet and made a lexical analyser generator. I also have another class about geographical information systems which I will be using my engine to create some demos for some 3D rendering techniques like level of details or maybe create something similar to arcgis which we will be using.
Oh man I have many stuff I want to do.
Here is a gif showing the state of my minesweeper game. I clearly lack artistic skills lol. One thing I will be making is to model the sphere as squares not triangles.
Finally I want to mention that I months ago saw someone here at devrant making a voronoi diagrams variant of this which inspired me to make this.
I made long post so
TLDR : having fun reinventing the weel and learning 😀

Do compiler engineers compile compilers? 🤔

So recently I did a lot of research into the internals of Computers and CPUs.
And i'd like to share a result of mine.

First of all, take some time to look at the code down below. You see two assembler codes and two command lines.

The Assembler code is designed to test how the instructions "enter" and "leave" compare to manually doing what they are shortened to.

Enter and leave create a new Stackframe: this means, that they create a new temporary stack. The stack is where local variables are put to by the compiler. On the right side, you can see how I create my own stack by using

push rbp
mov rbp, rsp
sub rsp, 0

(I won't get into details behind why that works).

Okay. Why is this even relevant?
Well: there is the assumption that enter and leave are very slow. This is due to raw numbers:
In some paper I saw ( I couldn't find the link, i'm sorry), enter was said to use up 12 CPU cycles, while the manual stacking would require 3 (push + mov + sub => 1 + 1 + 1).

When I compile an empty function, I get pretty much what you'd expect just from the raw numbers of CPU cycles.

HOWEVER, then I add the dummy code in the middle:

mov eax, 123
add eax, 123543
mov ebx, 234
div ebx

and magically - both sides have the same result.

Why????

For one thing, there is CPU prefetching. This is the CPU loading in ram before its done executing the current instruction (this is how anti-debugger code works, btw. Might make another rant on that). Then there is the fact that the CPU usually starts work on the next instruction while the current instruction is processing IFF the register currently involved isnt involved in the next instruction (that would cause a lot of synchronisation problems). Now notice, that the CPU can't do any of that when manually entering and leaving. It can only start doing the mov eax, 1234 while performing the sub rsp, 0.

----------------

NOW: notice that the code on the right didn't take any precautions like making sure that the stack is big enough. If you sub too much stack at once, the stack will be exhausted, thats what we call a stack overflow. enter implements checks for that, and emits an interrupt if there is a SO (take this with a grain of salt, I couldn't find a resource backing this up). There are another type of checks I don't fully get (stack level checks) so I'd rather not make a fool of myself by writing about them.

Because of all those reasons I think that compilers should start using enter and leave again.

This post showed very well that bare numbers can often mislead.

From NAND to Tetris..

This book is IMO the best book for those who want to venture to the lower level programming.

This books retrains you’re thinking, teaches you from the bottom up! Not the typical top down approach.

You begin with the idea of Boolean algebra. And the move on to logic gates.. from there you build in VHDL everything you will use later.

Essentially building your own “virtual machine”.. you design the instruction set. Of which you will then write assembly using the instruction set to control the gate you built in VDHL.

THEN you will continue up the abstraction layer and will learn how a compiler works, and then begin written c code that is then compiled down to your assembly of your instructions set to be linked and ran on your virtual machine you built.

All the compiler and other tools are available on the books website. The book is not a book where you copy and paste, run and done.... you kinda have to take the concepts and apply them with this book.

Then once you master this book, take it the extra step and learn more about compilers and write your own compiler with the dragon book or something.

Fantastic book, great philosophy on teaching software.. ground up rather than top down. Love it! It’s Unique book.

First year: intro to programming, basic data structures and algos, parallel programming, databases and a project to finish it. Homework should be kept track of via some version control. Should also be some calculus and linear algebra.

Second year:
Introduce more complex subjects such as programming paradigms, compilers and language theory, low level programming + logic design + basic processor design, logic for system verification, statistics and graph theory. Should also be a project with a company.

Year three:
Advanced algos, datastructures and algorithm analysis. Intro to Computer and data security. Optional courses in graphics programming, machine learning, compilers and automata, embedded systems etc. ends with a big project that goes in depth into a CS subject, not a regular software project in java basically.

HELL WEEK is coming!! they are going to make us code IN PAPER again.... no compilers, no way to check for errors, time to die again

So, for my C class, the computers in the lab are using VS 2015. To be able to compile C we have to change some settings to allow the program to compile.
I like to use my computer (with Arch Linux) and use my tools (Vim and GCC).

The guy next to me was trying to do the homework, but he was struggling. I decided to give it a shot and I was able to do it, so I showed him my code and he tried it in the computer.
The program crashes every time no matter what. We asked the professor. I show him my code and how it's working. Apparently he was confused because I was using the terminal and not VS. So he proceeded to said that it's because I'm not using VS2015 and GCC is doing the whole work for me.

I'm like ಠ_ಠ and then he keeps saying that he doesn't know what or how GCC works (for real? Someone that teaches C and has a Ph. D on CS doesn't now what GCC is?) but that it is apparently doing everything for me. So my code should be wrong if it crashes on VS2015.... ಠ_ಠ

What do you think? I'm thinking about talking with the head department of CS (I know that he is a Linux guy) and see what happens. Should I do it? Or should I just use VS2015 as the "professor" is asking?
I even tried online compilers to see if it was just working on my computer, but even they use GCC to compile.

It’s throw back Thursday!

Back to 1979... before the time of the red dragon book compiler book, (forgetting about the green dragon book) ... there was a time where only a few well written compiler and assembler “theory” books existed.

What’s special about this one? Well Calingaert was the co patentor of the OS/360. .. “okay soo? ... well Fred Brook’s Mythical Man-Month book I posted the other day. Calingaert is basically the counterpart of brooks on the OS/360.

Anyway, the code is in assembly (obviously) and the compiler code is basic.

Other than this book and from my understanding 2-3 other books that’s all that was available on compilers and assemblers as far as books written goes at the token.

ALLL the rest of knowledge for compilers existed in the ACM and other computing journals of the time.

Is this book relevant today, eh not really, other than giving prospective, it’s a short in comparison to the red dragon books.

If you did read it, it’s more of a book that gives you more lecture and background and concepts.. rather than here’s a swath of code.. copy it and run.. done.. nope didn’t happen in this book.. apply what you lean here

Coding is like cooking.

But only if
the heat source is lava. //Language
And the pot is lava. //IDE
And the food is lava. //Program
And the dishes are lava. //Classes
And the floor is lava. //APIs
And the tools are lava. //Compilers

Bit the bullet and installed VS and relevant compilers for C++ and started fucking around with sdl.

Not as terrible as I thought it was going to be.
Pointers seem pretty intuitive. Apparently my time with python has not in fact mentally mutilated me.

Annoyance in C: using the same keyword for two unrelated things, process-long memory allocation and internal linkage. Looking at you, static.

The latter should really have been called "intern", just like there is "extern". Far more people would use it if it was named correctly.

History says "static" was chosen for compatibility, allowing older compilers to take new source files.

Jeff Dean Facts (Source: God)

Jeff Dean once failed a Turing test when he correctly identified the 203rd Fibonacci number in less than a second

Jeff Dean compiles and runs his code before submitting, but only to check for compiler and CPU bugs
Unsatisfied with constant time, Jeff Dean created the world's first O(1/n) algorithm

When Jeff Dean designs software, he first codes the binary and then writes the source as documentation

Compilers don't warn Jeff Dean. Jeff Dean warns compilers

Jeff Dean wrote an O(n^2) algorithm once. It was for the Traveling Salesman Problem

Jeff Dean's watch displays seconds since January 1st, 1970.

gcc -O4 sends your code to Jeff Dean for a complete rewrite

well, for now, my biggest dev ambition is to become a compiler designer/programmer... or OS designer/programmer.
In short, systems programmer (compilers or OS).
😅😅😁😁

Normal Compilers : i guess you missed a semicolon in line 63

Special Compilers : You wrote wrong code, useless fella, I'm not your servant to tell you all the errors. Your mere existence is unnecessary and useless

In school we got asked 4 our future jobs. I saif: im gonna get informatician, because im already really good at it... Look, i can evem build compilers... In the break, my friend: could u program a game, dude? Me: no, im not using a graphical environnement. If i wanted to i would have to learn unity or flash or some sort of game engine He: then, ur not an informatician, and u shouldnt get one either...

Dont mess with compilers... Just follow there warning...

Person:"you're a dev, you must reeeaaaly get frustrated with semi colons 😏"
Me: "at times but it's not such a big problem with the compilers being better now.😊"
Person: "so innovative!😁"
Me: "nothing is innovative!! All new idea app ideas suck and there are not too many clicks!!! The icons are perfect!! Purple and orange buttons are not a good idea!!! What do you mean you want 3 buttons on the one screen that do the same damn thing!! Do you even think!! Oh of course the users are stupid, takes one to know one!!! Doesn't look like much?!!! Sure the backend is a mother fucking kraken the size of Michigan that runs smoother than a babies bottom but hey, let's bitch cause it's too plain on the eye!!!

Person: "new client? Or friend with an idea? 😒"

Parts of the code I am working on date back to the early nineties, written in ancient C++ with lots of special cases for ancient compilers by people with 0-2 years of coding experience.
My favourite coding moment is every time when after refactoring a part of the code, it has about 1000 lines less (no exaggeration), is more reliable, AND can do a lot more than before.

Compilers. Principle, Techniques & Tools aka Dragon book.

Java teacher writes code on blackboard in comp lab

He tells us to try it out at our workstations.

We do. The code does work. We tell him.

He says: "There is something wrong with your compiler..."

Question is...we were around 30 students. Can all our compilers not work if we had used the lab before and the code we run worked clean??!?!?!?

We were flabbergasted

Let's try this.

In the project I'm working there is an strict rule : NO COMMENTS!!!

I mean wth, the times I've spend hours trying to understand the crappy legacy code in VB.Net that has been there almost decades, that wouldn't happen with comments, I know i know there are some supernatural developers that think in binary and their eyes work as compilers, but I'm not like that, so seriously go to hell.

P.S. Of course I follow that rule, after all, my code is so damn perfect that even a baby can understand it.

Posting a meme found in Instagram instead of Reddit for a change

Fuck this shitty C ecosystem! Multible compilers, one standard complying, one hacked toghether? Only one GPL poisoned standart library, with no real chance of switching it, which prevents me of making staticly linked programs? And then there is microsofts compiler, with fucking ANSI support. Thanks. No dependency handling. Concurrency? pthreads. Are you fucking kidding. JSON? Have fun finding something static. Compile times where you can read entire books. Segfaults without one helpful info, so you have to debug with prints. And every library, every tool, installer, compiler, stdlib, anything is poisoned by GPL. But hey, its fast. And efficient. After you spend many slow and inefficient months developing something. I am so done with this shit.
Well.

Tommorow i will continue working with C on my backup project.

Did i mention that the stdlib has no features? Not even threading? Which is IN THE STANDARD?

Cross platform mobile with Xamarin, an internship asked me to learn Xamarin for them, I found that the docs Xamarin had were surprisingly helpful compared to other places

After continuing to pursue mobile with Xamarin I now feel I know multiple native apis very well (iOS and Android) and have found my favorite language (C#) so I've also learned a ton about how code and compilers work and all sorts of other things

Xamarin has been an incredible learning tool

A few years ago I would whine, complain and rant about shitty software, which I knew could be so much better than it was. But I didn't yet write software of my own.

Now I complain about shitty libraries, API's and users. Not much has changed really. And every time I write code, I curse myself, and whoever made this trashpile I have to work with. I curse the user to the moon and beyond for using the program wrong. Funny thing is, exactly the thing I was complaining about (input validation, see earlier rant) is also exactly what no more than 5 minutes after release, a user fucked up with. The bot just does not respond at this point. But fuck these braindead retards for users.

In a few years I expect myself to be complaining about shitty compilers and buffer overflows, segmentation violations, bad coding style (don't make your program a fucking colander kthx), and so on.

Next decade I expect myself to be complaining about physics itself, and why the universe is governed by the laws it's governed by. Whoever this God is, he's a fucking retard. Funny thing is, the signs for it are already there. Electron theory! If only those electrons were positrons, then the math would check out properly. Instead of negative electrons traveling from negative to positive, we'd have positive positrons traveling from positive to negative. At least from what I understand so far, this is still a decade away after all.

The point I'm trying to make is that nothing changes, only my understanding of the world around me does, as I tumble further and further down the rabbit hole. Sometimes I wish I had taken the blue pill... Either complain about others' software or perhaps not give a shit at all. Become one of those filthy users I now despise.

There are two kinds of programmers — those who have written compilers and those who haven't.
— Terry A. Davis

I fucking hate the process of setting up IDEs and compilers! All the build files, cmake files, tasks, all that shit.

I undrerstand it's integral part of coding, but fuck, why does it always take so long to set up a stupid project. Just let me start coding ffs.

Sometimes I get so frustrated that I rather write a bash script or run the compiler commands in the shell instead of going through the hassle of setting all this up.

I've been laughed at a lot for thinking this way, but I'm honestly frustrated by how little information exists on the web for people who want to take Operating System development a step further. I mean, the OSDev Community is amazing and offers pretty, much everything one needs to know at the system level. But my issue is: What if someone didn't want to use existing compilers and assemblers like GCC and NASM, and do everything from total scratch? I mean, the original Unix came from somewhere, right? I know you're going to think "Why not? It works.". Well, I just think it's crazy how few people (such as Linus and the GNU foundation) are out there that have the ability to create such things without help from existing software tools. Sure, it could take me decades of careful practice and experience, but my passion is for creating software at this level and becoming one of those people is very strong. I just wish I knew where to begin and who to learn from.

I would consider myself in the topper half of c++. I build compilers, i contributed 1000 linus to the linux kernel... But still: I am (only) 14 and lack experience... Could you please share some tipps for a young programmer... Not only for jobs, but also to improve more...

Turns out
if(double.TryParse(input, out double value)
{
//Do something with value
}

can't be used in compilers using C# versions prior to 7.0. Reason: → out double value ←

...k den

compile with gcc, ./a.out: "Segmentation fault (core dumped)"

compile with clang, ./a.out: runs and fails.

compile with cc, ./a.out: Alternated between "Error: Too many arguments" and "Segmentation fault"...

ffs I'm done for the week I guess.
The problem is not that it fails, the problem is that it alternates because of time of compilation, power consumption, random blody oracles or the phase of the moon in a leap year on a Friday the 13th. God.Please.Send.~Nudes~. Help.

Fellow Deviants, I need your help in understanding the importance of C++

Okay, I need to clarify a few things:

I am not a beginner or a newbie who has just entered this community...

I have been using C++ for some time and in fact, it was the language which introduced me to the world of programming... Before, I switched to Java, since I found it much better for application development...

I already know about the obvious arguments given in favour of C/C++ like how it is a much more faster and memory efficient than other languages...

But, at the same time, C/C++ exposes us and doesn't protect us from ourselves.. I hope that you understand what I mean to say..

And, I guess that it is a fair tradeoff for the kind of power and control that these languages (C/C++) provide us..

And, I also agree with the fact that it is an language that ideally suits our need, if we wish to deal with compilers, graphics, OS, etc, in the future...

But, what I really want to ask here is:

In this age and times, when hardware has advanced so much, where technically, memory efficiency or execution speeds no longer is the topmost priority... These were the reasons for which C/C++ was initially created...

In today's time, human concept of time matters more and hence, syntactical less complicated languages like Java or Python are much more preferred, especially for domains like application development or data sciences...

So, is continuing with C++, an endeavour worth sticking with in the future or is it not required...

I am talking about this issue since I am in a dilemma about the use of C++ in the future...

I would be grateful if we could talk about keeping AI, Machine Learning or Algorithms Optimisation in mind... Since, these are the fields in which I am interested in...

I know that my question could have been posted in a better way.. But, considering the chaos that is present in my mind, regarding this question doesn't allow me to do so...

Any kind of suggestion or thoughts would be welcome and much appreciated...

P.S: I currently use C++ only for competitive programming or challenges...

Seeing posts about standards vs implementation of compilers. People not getting that "standards release" != "vendor release" for C++ compilers.

At what point can I claim to not be a script kiddie anymore?

Like, I've built compilers, and interpreters for an excel-like syntax, I refactored a pdf-parsing library from the ground up. I managed databases and wrote protocols for communicating with hardware.

But most of my experience is with python / nodejs / golang. It is only recently that I started playing with C and rust for actual efficient system code.

I found a vulnerability in an online compiler.

So, I heard that people have been exploiting online compilers, and decided to try and do it (but for white-hat reasons) so I used the system() function, which made it a lot harder so i decided to execute bash with execl(). I tried doing that but I kept getting denied. That is until I realized that I could try using malloc(256) and fork() in an infinite loop while running multiple tabs of it. It worked. The compiler kept on crashing. After a while I decided that I should probably report the vulnerabilites.

There was no one to report them to. I looked through the whole website but couldn't find any info about the people who made it. I searched on github. No results. Well fuck.

Servey Question.

How many you programmers have a working knowledge of how compilers work? The philosophy and mathematics behind them. Different stages. The choices one might have to make at different stages. Reasoning about the said choices. Difference between different paradigms -- philosophically and implementation wise. The tools one might use.

Reason behind I'm asking this is that I got into a debate with a friend where he said 9/10 of people whom we call "developers" have little to no idea how compilers work.

!rant
All computers are great and not all people are compilers

Do y'all write compilers these days?

Can you post a link to any compiler you've written before.

Build apps for UWP, it will be fun they said. Yeah, created my first hello world app, which works btw. Added one f***ing button and compilers throws thousands of errors. Dude, I really enjoy it! :)

Well the company I work for was too cheap to buy a new Graphics Card so we got an old graphics card (nvidia) and had to install it with working drivers

We checked and the drivers were End Of Live since I think 2015 or 2011 so we downgraded the hell out of ubuntu 20.04 Kernel, Compilers and the driver installation still failed We had to get the gcc 7.2 but there wasn't any PPA's available with this anymore and the installation still failed without giving proper error message 11 Hours later we decided to go home

The next day we got an Email we wasted time and money of the company

but we were asked to do this.... (two working students getting minimum wage)

Q: "Babe, what's wrong?"
Women: "Nothing, its just fine"
Compilers: "Object reference not set to an instance of an object"

Ignore every single comment that had been passionately written into the code.
Probably thought "if compilers can, why can't I?".

When your code compiles on your machine but on another machine it fails.

(a question)
so in my city there's an opportunity for some
tech university students to attend extra programming classes for a year (12 hours/week). they'll teach many things: (advanced) data structures, databases, oses, computer networks, compilers, making games, data analytics etc. is it worth attending or i should just write down those topics in a to-do list and learn them by myself? i've never attended such courses so i don't know if they are useful or not. thanks for taking the time to read this :)

If you asked me two months ago I'd have said building and using a Barnes Hut tree with CUDA.

Today my answer is working on a fuzzer with LLVM without knowing shit about either C++ and compilers.

Didn't think I had material for a rant but... Oh boy (at least at the level I'm at, I'm sure worse is to come)

I'm a Java programmer, lets get that out of the way. I like Java, it feels warm and fuzzy, and I'm still a n00b so I'm allowed to not code everything in assembly or whatever.

So I saw this video about compilers and how they optimize and move and do stuff with the machine code while generating the executable files. And the guy was using this cool terminal that had color, autocomplete past commands and just looked cool. So I was like "I'll make that for my next project!"

In Java.

So I Google around and find a code snipped that gives me "raw" input (vs "cooked" input) and returns codes and I'm like 😎. Pressing "a" returns 97 (I think that's the ASCII value) and I think this is all golden now.

No point in ranting if everything goes as planned so here is the *but*

Tabs, backspaces and other codes like that returned appropriate ASCII codes in Unix. But in windows, no such thing. And since I though I'd go multiplatform (WORA amarite) now I had to do extra work so that it worked cross platform.

Then I saw arrow keys have no ASCII codes... So I pressed a arrow key and THREE SEPARATE VALUES WERE REGISTERED. Let me reiterate. Unix was pretending I had pressed three keys instead of one, for arrow keys. So on Unix, I had to work some magic to get accurate readings on what the user was actually doing (not too bad but still...). Windows actually behaved better, just spit out some high values and all was good. So two more systems I had to set up for dealing with arrow keys.

Now I got to ANSI codes (to display color, move around the terminal window and do other stuff). Unix supports them and Windows did but doesn't but does with some Win 10 patch...? But when tested it doesn't (at least from what I've seen). So now, all that work I put into making one Unix key and arrow key reader, and same for Windows, flies out the window. Windows needs a UI (I will force Win users, screw compatibility).

So after all the fiddling and messing, trying to make the bloody thing work on all systems, I now have to toss half the input system and rework it to support UI. And make a UI, which I absolutely despise (why I want to do back end work and thought this would be good, since terminal is not too front end).

Writing tokenizer for a new language.

god damn it c++, you and your ambiguous, contextual grammar!

currently working on a c++ and c parser, went from trying to use a parser generator to now writing a parser by hand.

If you're working on close to hardware things, make sure you run static analysis, and manually inspect the output of your compiler if you feel something's off - it may be doing something totally different from what you expect, because of optimization and what not. Also, optimizations don't always trigger as expected. Also, sometimes abstractions can cost a fair amount too (C++ std::string c/dtor, for example, dtors in general), more than you'd expect, and in those cases you might want to re-examine your need for them.

Having said all that, also know how to get the compiler to work for you, hand-optimization at the assembly level isn't usually ideal. I've often been surprised by just how well compilers figure out ways to speed up / compactify code, especially when given hints, and it's way better than having a blob of assembly that's totally unmaintainable.

Learnt this from programming MCUs and stuff for hobby/college team/venture, and from messing around with the Haskell compiler and LLVM optimization passes.

Best thing: I started to understand how compilers work under the hood (sort of), was even able to implement a few scanners already

Worst thing: I have absolutely no clue how to continue ._.

What IDE/Compilers do you guys use?

"Reflective" programming...

In almost every other language:
1. obj.GetType().GetProperties()
or
for k, v in pairs(obj) do something end
or
fieldnames(typeof(obj))
or
Object.entries(obj)

2. Enjoy.

In C++: 💀
1. Use the extern keyword to trick compilers into believing some fake objects of your chosen type actually exist.

2. Use the famous C++ type loophole or structured binding to extract fields from your fake objects.

3. Figure out a way to suppress those annoying compiler warnings that were generated because of your how much of a bad practice your code is.

4. Extract type and field names from strings generated by compiler magic (__PRETTY_FUNCTION__, __FUNCSIG__) or from the extremely new feature std::source_location (people hate you because their Windows XP compilers can't handle your code)

5. Realize your code still does not work for classes that have private or protected fields.

6. Decide it's time to become a language lawyer and make OOPers angry by breaking encapsulation and stealing private fields from their classes using explicit template instantiation

7. Realize your code will never work outside of MSVC, GCC or CLANG and will always be reliant on undefined behaviors.

8. Live forever in doubt and fear that new changes to the compiler magic you abused will one day break your code.

9. SUFFER IN HELL as you start getting 5000 lines worth of template errors after switching to a new compiler.

So I just read up on what the language D has to offer. It seems quite good!
- Active community
- Multiple compilers
- Modern (no header files, garbage collector, etc.)
- No VM or framework needed to run it (like C# and Java)

Looking forward to trying it out!

Does anyone have any experience with it? What are your thoughts?

Anyone able to link me to some good reading material on compilers, interpreters, emulation and CPU design?

Keen to actually get some of this knowledge under my belt, don't mind if it requires a little investment as long as it isn't written in (fucking) python, preferably C if anyone knows of anything.

Thanks guys! :-D

!rant :) FUUUUUUUUDGE YEAAAAH!
it's so satisfying when you've been working on a huge ass thing(when maybe you should have tested individual parts) and it just fucking works as intended amazing, I love it!

It's so beautiful to see your own compiler(jk just scanner+parser atm) compile code successfully

Compilers should just work for raw C with only static memory allocation. This isn't the bad old days where a couple of dudes wrote a short book explaining how C might probably should possibly work. I hear supposedly we have standards now.

Well, last week I lost 2 days to our compiler randomly forgetting that it wasn't okay to put a globally allocated uint32 at an address ending in 9. What? It had been handling this case without issue for more a year, but now after changing completely unrelated code we have this problem.

I'm not sure how to even deal with this idiocy so no doubt I'll continue working on it this week, too.

Thanks a lot, GCC.

Hey this is Linuxer4fun or BinaryByter, you might remember me as that smartass Teen who fanboyed over C++ and built kernels and compilers and all that shit. Well...

Ultimately i must admit that I have moved away from Programming. I dont have any Projects I could acomplish which would be worth my time, I cant come up eith any, to say the least.

Additionally I'm demotivated as hell because I'm always tired due to my Hourlong Organ-Practice sessions and very long school times.

I think that I want to major in Music.

So incase you wondered, thats where I have gone to. I might still lurk here, and maybe someday i'll restart coding. I hope that I will, because coding was loads of fun!

Having other people pitch you to hiring managers, raise the hype, and profess faith in your abilities is kind of nerve-wracking. But I found a tutorial to teach me how to write a compiler and it’s not in a language I know, so that’s fun and distracting. Been up since 4am. Is now 12:30am. Should probably sleep.

so llvm core was written in c++
and it's used to build good compilers.
and they used it to build llvm-g++, a c++ compiler (now deprecated)

huh...

A bit confused

I have a code and it is giving different answers in different language and compilers
the code is

Int a=4
Int b = ++a + a++ + --a

Please ignore the syntactical errors
But this logic give different answers in different compiler and language like in
C(turbo c++ compiler) it gives 12
C(gcc)- 16
Java- 15
Python- 12

Can anybody explain the logic behind this...

Today was a rather funny day in school. School starts for me at 13:40 because our timetable planners are so qualified for this job.

First 2hrs: Physics, fine its good

Second 2hrs: Discrete Maths (however you want to call it)
Goal is to write a text (30 pages, 10, etc all those standard settings). Teacher prefers Latex over word, but we can do it in word if we want. We could choose a topic, I took primes because it looked the best. I decided to use latex because I'm a fetishist and it simply looks better in the end. A classmate was arguing with our teacher about ides: texmaker vs kile. And I'm like "I use vim". So my teacher is like kk

Later that class, when we actually started doing stuff I started the ssh session to my server because I don't know any good c++ compilers for win and I'm too lazy to get a portable version of cygwin (or whatever its called). So in my server I open vim and start coding my tool for Fermat Primes (Fermatsche Primzahlen, too lazy to actually translate). And this teacher seriously is the best teacher I ever met in my life. Usually teachers are like " dude r u hakin' the school server?" and I'm like bruh its just vim and I'm doing it this way because I cannot code on your PC coz I can't install a compiler. And this teacher is like "oh hey you actually use vi, all cool kids used it in 2000. I first though u were kidding and stuff..." And we continued talking about more of stuff like that and I have to say that this is the first teacher that actually understands me. Phew

Now I'm going to continue writing my 30 pages piece of trash latex doc and hope it'll end good

Why use Clang over GCC?

Oh god, structure alignement, why you do this... You might be interested if you do C/C++ but haven't tried passing structures as binary to other programs.

Just started working recently with a lib that's only a DLL and a header file that doesn't compile. So using python I was able to use the DLL and redefined all of the structures using ctypes, and the nice thing is: it works.

But I spent the whole afternoon debugging why the data in my structures was incoherent. After much cussing, I figured out that the DLL was compiled with 2 bytes packing...

Packing refers to how structures don't just have all the data placed next to each other in a buffer. Instead, the standard way a compiler will allocate memory for a structure is to ensure that for each field of the structure, the offset between the pointer to the structure and the one to the field in that structure is a multiple of either the size of the field, or the size of the processor's words. That means that typically, you'll find that in a structure containing a char and a long, allocated at pointer p, the double will be starting at p+4 instead of the p+1 you might assume.
With most compilers, on most architectures, you still have the option to force an other alignment for your structures. Well that was the case here, with a single pragma hidden in a sea of ifdefs... Man that took some time to debug...

bro look how cool i am haha lol i know java c c# angular react and php lol haha infact bro i created couple compilers haha lol bro vscode bro more like vssucks lol i use Google Docs for coding haha bro what is windows i use Ubuntu lol for that alpha sigma grindset life haha lol just update 1000 packages a week bro i play with the bootloader like messi plays football bro haha bro i can't exit vim bro i basically stay in it haha lol bro i know all about AI haha LLMs haha im taking an inteview, a shit and solving complex neurological simulations at once bro haha i wear dev related tshirts haha lol bro my house is built on Alexa bro haha ALEXA TURN ON THE LIGHTS see how cool it is bro haha i use OAuth everywhere bro to gain access to my toilet seat haha lol my thumbs hurt so bad lol bro cuz I code all day long bro what are weekends bro I never take leaves bro haha have to stay on that sigma side hustle culture right haha look how many stickers i have on my laptop haha im so cool haha lol.

compiler distancing

My Mentor during the 1st year of my College

Set High Expectations and very frequently used to throw insults and shame me as if I knew nothing. And he was not wrong. I sucked so bad. Did learn some basics and promoted me one level from the "total newbie" state

But my best Mentor would have to be my PCs, Compilers, Debuggers. Couldn't find a better one

Can anyone help me with this theory about microprocessor, cpu and computers in general?

( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)

How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.

Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.

Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?

Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.

Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B

On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)

Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.

The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.

My problems:
1. Is this all correct? Does this only happens?

2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.

Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(

I'm searching for some stuff on creating compilers, interpreters.
I couldn't find something really good on the internet so far, so if you know some good resources, I'd be happy to know them.

Got VS running, SDL up and running and outputting, and angelscript included. Only getting linker errors on angel at the moment, not on inclusion, but on calling engine initialization.
Who knows what it is. Devs recommended precompiling but I wanted to compile with the project rather than as a dll (maybe I'm doing something stupid though, too new to know).

Goal is to do for sdl, cpp, and angelscript, what LOVE2d did for lua. Maybe half baked, and more just an experiment to learn and see if I can.

Would be cool to script in cpp without having to fuck with compilers and IDEs.

As simple as 1. write c++, 2. script is compiled on load, 3. have immediate access to sdl in the same language that the documentation and core bindings are written for.

Maybe make something a little more batteries-included than what lua and love offer out of the box, barebones editors and tooling and the like, but thats off in the near future and just a notion rather than a solid plan.

Needed to take a break from coding my game and here I am..experimenting with more code.

Something is wrong with me.

Today I realized that compilers are children, and must be treated as such. Generally, you might tend to expect a language to follow the same rules consistently, but oh how wrong you are, my sweet summer child.

I have a framework that I've been reusing across several personal Unity3d projects for a while, and all was well. This week, I was tasked with creating a PoC that combines a web app with Unity WebGL for data visualization. My framework has a ton of useful stuff helped me create the PoC very quickly, and all was well.

Come 3 days ago and there's one last piece that isn't working for some reason. It almost appears that this one bit of code isn't executing at all. Today, after countless hours of swearing at the computer and banging my head against the wall, I realized that the WebGL compiler has a different implementation for the method that checks assignability of types. An implementation that has different rules than everything else. An implementation that has no documentation about this discrepancy anywhere. I have no words.

tl;dr: The language changed the rules on me. Fuck me right?

I prefer starting from theory and then proceed with practicing. For example, to learn haskell and deeply understand it, I started by taking a course in category theory and I already have a degree in computer science and then start writing actual code. The same with JS. I started with theory for JIT compilers and studied how V8 works, how it utilizes event loops and how they are implemented in the kernel. Then I started experimenting with code and demos. It's a success path for me, that has worked every time with every new technology.

A long time ago in a decision poorly made:

Past me: hmm we're having trouble getting IT to give us a new build machine with the new compilers.
Past me: I know we'll just use one of the PCs that belongs to a member of the team to tide us over.

[2 months pass]

Present me: that's odd, Jenkins is really slow today.
[Several minutes pass]
Present me: holly shit fuck; it's building the whole weekends worth of builds at 9am on a workday and eating licenses like a cast away that suddenly teleported to an all you can eat buffet.
Present me: [abort, abort, for the love of fuck abort]
Present me: contacts IT, they can't find any problems, wtf happened.

Present me: discovers team member turned off his machine on Friday and builds had been stacking up all weekend.

Lessons learnt: disable power button on team members pc and hire a tazer guy to shoot whenever someone goes near the wall socket.

1 hour lost and no build results for the last 3 days.

It's looking like a bad morning

Kinda often, the ecosystem around C/C++ kinda sucks

Compilers will give you hieroglyphs instead of readable errors.
Including a separate library, or a code generator, into your project is generally hell on earth to set up.
The language server often needs several seconds to come up with suggestions, some of which are complete nonsense.
The language itself lacks many basic features. C++20 will give us so many fancy things but we still can't convert an enum to a string.

I've programmed in C# and lately in Rust, and damn the developer experience there is just so much nicer overall.

I just learned C and I have created some projects like Parking System and Library Management System. My problem is I don't know mathematics and I want to learn DataStructures & Algorithms and become pro in it. In the whole September I will still be focusing on C and create more projects. I have started learning Mathematics today from High School level to College level. I thik maths will take 1 year to complete. After September in the October I want to start learning C++ and finish C++ till the end of Dec 2019. I want to know that do I have to first finish my maths learning which will take 1 year then I should start learning Data Structures and Algorithms? As I said I want to become a professional in Algorithms. I think its not possible to learn DS&A yet I have to wait 1 year till I finish learning my Maths. I can't do more with C & C++ without knwoing DS&A? If I started learning DS&A with C++ in the future then I can't become good at algorithms? I want to do competitive programming and be at Top 1 of Hacker Rank and other sites like this.

Some compilers give an error message on forgotten type casting. From that it shows good typing style casting. So you also avoid clerical errors that can lead to the program crash in the worst case. With some types it is also necessary to perform type casting comma on others Types, however, do this automatically for the compiler.
In short:Type casting is used to prevent mistakes.
An example of such an error would be:
#include <stdio.h>
#include <stdlib.h>
int main ()
{
int * ptr = malloc (10*sizeof (int))+1;
free(ptr-1);
return 0;
}

By default, one tries to access the second element of the requested memory. However, this is not possible, since pointer calculation (+,-) does not work for a void pointer.
The improved example would be:
int * ptr = ((int *) malloc (10*sizeof (int)))+1;

Here, typecasting is done beforehand and this turns the void pointer into its int pointer and pointer calculation can be applied. Note: If instead of error "no output" is displayed on the sololearn C compiler try another compiler.

I just thought. The next generation of coders are going to curse the software we praise. Well be using JavaScript to drive cars and ATMs (if we aren't already). We're gonna talk shit to dev youngsters about compilers, shims and fucking cross browser compatibility and how good they have it. Some of us will be stuck in the past keeping bullshit legacy code alive. Besides that, the world is gonna be a fucking awesome place (rip Mahammad Ali)

I want to build sentiments into the lexical analysis part of compilers, just so that every time my coworker tries to compile his "work", the computer prints,
"*sigh* Brian, just... *sigh*"

CUDA is a fucking bitch when it comes to configure projects

Creating my first CUDA project it yelled at me it doesn't support my current gcc version, ended up with me yelling back "OY SHUTUP" and slapping some flag for it to use clang instead — basically what it advised but I didn't listen first. Fine now.

Working on this project on another fresh environment, and now it doesn't detect anything and dumbly tries to reload my CMake project with the LATEST installed gcc when I already told it to use version 8 TWICE. First by setting up a toolchain with compilers pointing to this specific version and second by passing the -DMAKE_C_COMPILER pointing to it again. Still this stubborn piece of shit tries with latest everytime.

The most applauded solution was to use update-alternatives to make gcc point to the version I want CUDA to use. Thank you genius, but what if I don't want to use a deprecated gcc version with normal Cxx projects ?

And cherry on the top of this bullshit, I'm fixing this dumb configuration issue (can't stress enough how much I hate this shit) to be able to fix an EVEN MORE annoying issue with CUDA being a bitch AGAIN and not letting me use std functions where I'm allowed to

Fuck CUDA. Fuck CMake. Fuck C. Fuck everything

I see a major shift coming up im regards of how we continue to evolve the way our applications work in regards to web based solutions. Http was not meant to do the shit that we are doing today, yeah it works, but it continues to feel like a hack. The advent of A.I and WebAssembly will probably make developers more mindful about compilers and truly optimized code. Languages such as Rust are pointing in the right direction in terms of speed and safety and as our computers become more powerful so will our way to communicate with them. Eventually damn near every web based solution will include A.I even when it is not needed at all.

Regardless of what happens. Yo ass is not going to stop hearing about C++, SQL, and Javascript(top kek)

I'm in a big fat fucking stinking rut, as in progress on this project has absolutely stagnanted.

Gonna rubber face your duck now **UNZIPS** excepts I don't have zippers, as joggers are the one true way; fake Adidas til I fucking drop.

Brain damage aside, I understand both how I've layed out the data and what I'm supposed to do with it. We have a virtual machine, an array of instructions and arguments for a given process within it, and we need to walk this array and map values to registers.

We also need to spill values inside registers to stack, IF they are required at a further point within that block. This also isn't terribly complex. We simply look forward in the array and see if the value is an argument to any instruction that *needs* this value to be loaded (ie, within a register).

So this implies multiple iterations; we need to better understand how one particular value is used throughout an F before we can make a final decision on how many registers and stack space are actually needed for the whole block.

Here's where it gets tricky. If there's a call, we need to be certain that the symbol being invoked has already been fully processed. Besides the obvious fact that recursion fucks me up, there's another matter: say a private method gets invoked by another private method. We can take advantage of this, by which I mean, sacrilege incoming so put on this toga.

Looking at the output for C compilers, it would seem this is not done in practice, I would assume because it's a pain in the ass. But when you have the guarantee that F will only be called internally, as that's what "private" means, there's two ways it can go:

0. It's well below the 13-20 cycle threshold, so you inline the fucker. No suprises there.
1. It's a more involved affaire, and invoked in more than one place, so you don't inline it. Codesize matters.

Recursion and [1] are the big deal things holding me back. Not because it's too hard, like I said this is kindergarten level abstraction. I'm just slow and fanatical, which is how I prefer to spell "constant obsessive paranoid delusions". I can see the potential optimization I can pull here, so I'm stuck trying to figure it out.

Idea would be, handling the register allocation and stack spill for an internal-internal (or deep internal; what we like to call a "guts" method) in synchronization with the *calling* processes. This is, fundamentally, violating all conventions -- but so under the hood no one will notice.

Let me give you an example. If we were to pass some value to a function, expecting to mutate it and get a different value back, in a lot of cases it'd be stupid to make an implicit copy by using two registers, one for input and another for the output. Dude, it's one cycle. Multiply it by a million, say sixty times per second, for every time you __needlessly__ make a copy of a value that we've already stated is mutable.

Clearly unacceptable. This is, in the strictest sense, everywhere in every single codebase. Premature micro optimization is the root of all goodness, God is great and praiseworthy. So how do we go about it?

Answer is I know and I don't know. By which I mean to say, this very thing I've done by hand. Assembly is fun. Now the issue is teaching a calculator how to do it. Not so fun.

There is a dependency chain between processes, as I believe I've kind of alluded to. I'm trying to make decisions on the side of the caller depending on the details of the callee, which is why recursion is rawdogging my soul. This is the same situation, it's inverting the direction of one or more links in the dependency chain, which makes no fucking sense.

And yet it does.
Brain, explain yourself.

How do *you* handle this without crashing?
Brain?

<<ME STEWPED; BEEP-BOOP>>

Alright then, that was a useless attempt at fuckery. Let's have a nap then, maybe it'll come to me in the morning. That's what I've been saying to myself for almost a month now.

Perhaps it is a hardcoded fuk.

Not a rant, but I'd love to see three top notch developers, doing a coding challenge, in the same language, without any text editors, IDE's, compilers ( other than pre-installed ones ) when they start, working on 'their' most unfamiliar OS; the three OS options being Linux, Windows & OSX.

Any opinions on who might complete first?

Saw a CSS troll post, here's a general development troll post.

Replace every semicolon (;) with a greek question mark (;) in your colleague's code and watch the compilers, runtime environments, and your colleague scream.

(heading)How a programming language is created? Because I want to make my own.(heading)

I am learning C and next I will learn C++, SQL,DS&A, Assembley, Lex&Yacc,Operating Systems, Computer Arcticture, Computer Networks because I think it's enough for my goal. The only reason I am learning this, to make my own C++ clone with my own knowledge. But I really don't know how can I create my own programming language like C++ from scratch. Like what are the first steps to began with. As I know that C, first step is Preprocessor then Compiler then Assembler then (Loader/Linker).

Anyone please give me a step by step guide like learn this language first then this then this. So I can finally reach that amount of knowledge which I can implement to create my own programming language like C++.

The old blue screen on c IDE always felt 1990's star Trek.

So I am usually more of a classical backend/ app developer guy. I like my Local compilers/interpeters whatever. Recently though i kinda started thinking about how Web Apps work, and how to actually make one, which lead me to the Realisation that i actually have no idea how any of it works. So I started a little private project using django, as I am quite good with python. But soon after starting i realized that that wouldnt be enough, i would need to learn the basics as well as a couple of languages.

So can the community recommend me some books and learning material on JavaScript, HTML and CSS as well on general Web development ? While we are at that matter, can someone give me a rundown on what the differences between Javascript, angular, jquery etc are?

Best part of being a dev?
The ability to browser through the file system of online c/c++ compilers 😅

C++ is the building blocks for many high-level programming languages, and since 1984 its first appearance in the markets the C++ core committee developers have introduced its 4 new versions which are C++03 (ISO/IEC 14882:2003 second edition), C++11 (third edition), C++14 (fourth edition) and C++17 is the fifth edition. With each new version, developers introduced new features, libraries and APIs in it.

C++ introduced as the extension of C programming language which made C++ as a compiled programming language, which means the developer required a C++ compiler to translate the C++ code to its equivalent machine or byte language, so the Operating system of the computer can execute the program.

There are various C++ compilers in the market and most of them are open source and free to use, however conventionally when we say C++ compiler, we basically talk about GCC which stands for GNU Compiler Collection.

What is GCC?

GCC stands for GNU Compiler Collection, and it is a collection of programming compilers which induce C, C++, Objective-C, Fortran, and some versions of Java. The first version of GCC introduced in 1987 and it was also known as GNU C compiler which became the standard compiler for C programming language, in that same year GCC also provided Compiler support for the C++ programming language.

Now GCC has various versions and each version give specific support for C++ versions, by now if we look at all the versions of GCC, we have a stable GCC for every version of C++, but there are some exceptions with C++11.

C++11:

C++11 introduced as the 2nd update version of C++, it suffixes 11 because it released in 2011 or because on August 12, 2011, ISO gives official approval to it. Formally C++11 known as C++0X because developers were expecting the new update released in 2010, but with its release in 2011, the core committee developer of C++ changed its name by C++0X to C++11.

C++ 11 replaced the old version of C++03, and it also brings many new features for the C++ developers. The main aim of designing C++11 to stabilize and maintain the backward compatibility of new C++ version with the C+98 and C programming language and that’s become the main reason why core committee developers only introduced new features in the old standard library rather than extending the core language.

 

GCC does not give Full Support to C++11:

GCC version GCC 4.8.1 purpose the first feature-complete implementation of the C++11 standard, however, the 4.8 and 4.7 does not give the full support for the C++11. The current version of GCC provides the major support for all the standard features of C++11 but if you are using the GCC 4.8 or 4.7 versions then your GCC only provide you with the experimental support for the C++11.

To use the Experimental support of GCC you need to enable it first before you compile or run you C++ 11 version code.

use code std=c++11 or -std=gnu++11 to enable the experimental support for C++11.

Can you take this JavaScript file and make it TypeScript with tree shaking. Step one pass week to understand TypeScript and webpackShit compilers and try to importe it in a basic chrome windows ... What a mess

Lex Luthor is friendlier than LEX... 😪😪

Should someone try to verify what they trust, they will find themselves on the shore of infinite, immesurable void. This void is aggressively anti-memetic: it exists, we know it exists, but it's practically unknowable.

Have you ever tried so much as compile your entire OS and all its programs from scratch? I know it's possible, I know there are people somewhere who do it, but have YOU personally tried that? Did you compile every part with multiple compilers to verify that your compiler isn't compromised? You can talk the talk, but have you walked the walk?

The food you eat every day. Did you make sure that it only contains what the label says it contains? Have you checked it with the lab? Have you then checked the lab itself? Did you check their equipment? The firmware their equipment runs? Purity of test mediums and reagents? The equipment you used to check the purity?

As I type that, I want to smack myself in the face. My brain aggresivelly rejects the idea that it needs to check everything itself. More specifically, the idea that the amount of trust it puts into other people it doesn't even know is INSANE. Here this void is -- known, but unknowable.

Do you remember the shore? It actually was _your_ shore -- you yourself is just an island floating in this void. Other people are islands too. Or bubbles, or, more specifically, entities that live within those bubbles. The bubbles made of beliefs and assumptions that form their hosts' realities.

With natural language, you build bridges to other islands/bubbles. The natural language itself is a thing that you don't really know -- you use it, yet you (and no one else for that matter) can guarantee that other person you talked to understood exactly what you was trying to say.

This black sticky void can consume us all at any moment. Yet, it chooses not to.

This void is god.

I have poor grammar

It's most likely that your brain might not construct a parse tree for it🎄

How can a LaTex document simply stop compiling after some months? Is this shit not downward compatible with newer versions? This stupid language and all those fucking compilers this is the worst user experience ever. Gonne re-type the thing in Word now

the Cloud... all of it. All your compilers are belong to me.

Need a book recommendation:

What is the best textbook on compilers for _beginners_? I am an entry level dev from a non-CS background and I have _zero_ knowledge of compilers.

Is there any kind of protocol/method where I can use something like docker containers in order to "host" compilers like gcc and use that with vscode to compile and assemble source code?

No I'm not talking about volumes (it's a bit tedious if I want to use it to manage numerous projects)

It baffles me that although all they're doing is shuffling numbers around based on abstract descriptions of the target architecture and platform-specific behavior is completely out of the question, compilers are some of the least portable programs in active development.

What do I need to start coding and running python on Windows 10? I mean what do I need to set up and instal like compiler and others..
Also if you could please recommend me some good free compilers and stuff!

I get to make things others havent yet.

well, one day.

and it's the best excuse I've found so far for binging technical subjects and papers.

also because when talking with people about say, compilers and how they're made, or machine code, or a dozen other topics, people dont roll their eyes like I'm speaking a foreign language.

also the occasional math shitpost makes it worth it.

The reason there aren't independent web browsers anymore is that the web standards include a lot of concepts that should never have been standardised and their presence in the browser as opposed to compilers and interpreters targeting the web has no benefit whatsoever.

"X is dead! My project has just gone up in smoke, because docs/programs have been permanently lost."

This time, it's Sun. No one's dumped their compiler package CDs for Solaris, and now you can't order them. Whoops! There's like 5 versions of Solaris that have SDKs and docs that are just gone.

Dump your CDs, you stingy motherfuckers. "oh they're stamped, they have my name in them, i paid $600 for the license" do it anyway, because time is unrelenting and the rot claims us all. we must run faster than it does, and you're just standing still.

I just realized: People bitching about JS standard library, bundle size, need to use polyfills etc - is useless IMO. We need to start viewing transpilers as compilers and overall JS ecosystem like we are developing something in ActionScript Flash/Java Applet and exporting it for use inside browsers. And forget about "bad parts" of standard clean JS overall. See clean JS like it's as bad as it was in the past. (because without polyfills you still don't have most of the major es6 features in the IE browsers)

In the past we needed Flash plugins, Java plugins for applets, and they had size way larger than average JS bundle nowadays.

What you think?

i am having a feeling that getting into software branch of it industry might be a wrong decision. in my college years, i got to explore different domains in tech :

1. software development : frontend tech , backed tech, mobile tech : somethings i and a million other people know

2. os and internal softwares : os, compilers, processor coding , chip manufacturing etc : don't know what this industry is known but we devs rarely go that deep in the hole

3. the network industry : computer networks , topologies, packets, data transfers etc. again not sure what this industry is but 4g/5g brands/ cisco seems to making a lot of money with this

4. cloud computing, devops, data etc : i guess some backend devs explore this domain too.

5. ai/ml data sciences/web3 : the new fad

6. biotech :?? don't know anything about this at all

7. graphics/management/qa : the other associated sisters of software dev. they are seeing a similar recession

8... ans so on.

i chose the 1st one in my undergrad as my career and now regretting this i am thinking of doing masters to fix my mistake and take a job in some other industry that is still blooming and has a future for sustaining a recession for atleast 30 years.

so any suggestions/experiences?

Does any of you have the compulsion to micro-optimize every bit of code that you write? How do you deal with it?

I'm not just talking about algorithmic optimizations, but the real nitty gritty stuff. I'm talking about using bit fiddling to avoid if statements where speculative processors might make mispredictions. Anything that might make a program compile to fewer machine instructions or avoid extra stack frame overhead.

This all started a year ago when I took a systems programming course at my university, and started learning C and C++. But I find myself doing this in the wrong places. Who cares if this trivial program that I wrote runs in 1.2 or 0.6 seconds? My future employers won't care if my code is 10% more efficient when it takes four times as long to write.

It's gotten to the point that I can't bring myself to use languages like Python because I don't know how it's implemented under the hood and can't predict how the different ways I could write a function will affect performance. How do I bring myself to trust that the compilers (or interpreters) and the programmers that wrote them will be sufficiently optimal, and just move on? 😩

Hi everyone, I’m a college student and I have a career question.

I was contacted by a company to apply to their recent graduate program and it seems like a great opportunity for me. In the program, they assign you to a team (AI/ML, computer vision, automation, compilers, web dev, etc).

I need to send them my resume. I want to work with their computer vision team (I took a computer vision class and fell in love with it) but my resume only has web dev roles (I’ve only had web dev internships).

I’m worried that because my resume only has web dev stuff, I will be assigned to their web dev team instead of their computer vision team.

I really don’t like web dev anymore and I’m not sure how I can express that. Any ideas? Should I add an blurb in my resume expressing my passion for computer vision?

I learned to code on a jailbroken iPod touch around 2009. I wanted to compile some random project for jailbroken devices, but I had a windows comp (with dialup!!!), so I was like "why not do it on the iPod itself?". I didn't even have wifi, so I'd sneak out of my parents' house at night and steal the neighbor's (hey, I was 11 w/ overprotective parents who would freak out if I occupied the phone line w/ internet) to go read up on compilers, jailbreaking, etc etc. Eventually I got a working compiler and toolchain, but when I went to compile the project I wanted to use (and not just a test project that I found), it spat out errors. So I learned C/ObjC on my iPod. Turned out the project I was trying to compile was a load of BS, so I implemented my own version and put it on github. From a fuckin iPod. Win. It was some SBSettings control. Once upon a time, you had to jailbreak to get those cool slide up/down menus with the toggles for wifi, bluetooth, location, etc!!!

I hate Visual Studio. It takes 2 minutes to load- it is a glorified word processor- sure it has compilers but that's the backend work shouldn't be doing any of that at the start. It should take 10 seconds to load. It has absurd number of annoying checkers like unused attributes or function not initialized (constantly hits on Start ()in monobehavior) I even told to skip that nonsense and it still does it. It doesn't however check like infinite loops easily accidentally do. You can't duplicate a script because it can't do the simple thing of ensuring file name and class match.

I think maybe I am doing something wrong.

I have this node.js application I am building with typescript and I wrote tests in mocha. Now I need to make some changes which break quite a few tests.

When I run mocha on the command line the errors whizz past. When I worked in java and .net (with junit and nunit) you could just click a test in the ide to run it. So you could 'fix' one test at a time. Also you could just double click on a fail and it would jump you to the code for that test or the exception that failed.

I found this extension for visual studio code that adds a sidebar to visual studio code. It looked good but now I spent the last hour trying to get it to run typescript tests - looks like it doesn't support the compilers argument.

Surely other developers must do this sort of stuff. I am not using an obscure technology stack right? Do you write automated tests for your codebase? What tools do you use? Should I switch ide? switch testing frameworks?

Started with the old computer craft mod for Minecraft that put Lua into a form I could understand with clear goals (I was 12 or 13 at the time), and from there learned Java and some web dev tools. Now I'm here writing simple compilers to procrastinate uni work

!Rant
What books would you suggest for someone who wants to learn how to make compilers/interpreters?
Is the dragon book good for a complete beginner ?

So I'm writing my compiler and I decide to test error handling, see if I'm catching unexpected tokens and whatnot. I try duplicating a semi-colon at the end of a line, for sure it'll give me an error since that's an unexpected token, isn't it? So I run the compiler and... No errors? I start debugging for a few minutes, snoop around, everything seems ok... "Huh, that's weird" and then it dawns on me, a semi-colon only marks the end of a statement. So, technically, it's not an unexpected token if you have an empty statement (which wouldn't break any rules about statements). I decide to try out my theory. I put ;;;;;;;; at the end of a random line in my rust code, hit compile and... it compiles! So that means it is not a bug anymore! I mean, if the big guys that actually know a tad about language design, compilers and all that cool stuff allow it in their languages, why shouldn't it? So I did it, I turned a bug into a feature and now I can go to sleep in peace and stop dreaming about fucking abstract syntax trees (don't mind my kinks >:) ).

Yeah anyways thanks for reading, till next time! Bye!

Am I the only one who has made a semi-functional compiled programming language because they're bored?

I am learning C++ and I want to develop my own custom ROM for android from AOSP which is Android Open Source Project. I don't know anything about how to do it help on internet is not clear and on the Android official website there is no section for documentation and people on other sites say read documentation.

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

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

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

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

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

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

Usage:

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

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

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

LLVM is a cool thing to learn!

Hi fellow ranters, I humbly request your opinion on a matter.

I am a CS student in his last year of college, and currently developing a Node.js app as his final year project with a partner. The project has potential, and we've been at it for about three weeks, but the problem is that the more I code, the less I see myself doing Node in the future.

I was a total noob in CSS before starting the project, and I have learnt a ton in just 3 short weeks, but that has taken a toll on me, because I fell pretty far behind our schedule. However, for as much time and effort ad I have put in, my partner has put in a lot more (and he knows way more than me), thus increasing the gap.

My partner and I have (for the moment) different views on the amount of effort that we want to put in the project, since I see it as "slightly more than just another subject" (9-hr a week), and he sees it as a real passion project (endless hours). This could be due to the burnout of the first weeks, but I'm really not that excited about the project anymore, and I find myself thinking that I am wasting both of our time (I don't want to be dead weight), and that if I worked on a project that really made me passionate, such a compiler or a runtime environment, or a new programming language, I wouldn't mind putting in the hours that he does. Just to give more context, this whole project was his idea, and although I find it a great idea, and I know he is capable of building an amazing product, I am not sure whether I would be useful, or even if I want to be useful. Again, this could all be because of burnout.

Anyone has had such an experience?

TL;DR: I am working on a final project with a partner (it was his idea, and I found it interesting), but I think I would be happier switching to a project of my own.

When I try to install package 'cryptography' for Python,,, C++ and RUST compilers are launched by the pip package installer. The compilation fails. Is there any chance to avoid this error? 🐍🐞

So I’m taking a class on compilers (currently a college student) and as I get further into a coding project we have to do I can feel and see my code degrading into a giant mass of spaghetti. Although I know that I should refactor it because it is messy (currently trying to find a balance between refactoring and actually getting the assignment done) the scary thing is some students in my class think this is perfectly normal code and is what good code looks like. Scary thought that so many people graduating from university have no concept of object orientation, reusability, etc... but what’s even scarier is most professors could not give two shits about any of these notions. I guess this is the biggest reason why a computer science degree does not prepare you for a job in industry.

This Recursive descent parser is so fucking recursive.

defeat of compilers , misinformed co workers and the fine art of googling for information...

I was watching an Ancient Aliens episode called "Beyond Roswell". The show described the idea of some of our tech being seeded slowly by introducing alien technology to specific companies. They suggested that computing technology has advanced very fast and introducing this tech could be part of that.

At first I was kinda pissed about this. I have read about the creation of the first transistor back in the 40s or 50s. WWII really advanced our need for computing devices such as what Turing built. Then I realized a lot of the explosion of computer tech did occur after key ET events. This kind of made me wonder how much is "us" and how much is ET tech. I also realized it can take a lot of effort to understand something really advanced. So reverse engineering can take a LOT of effort to figure these things out. Being seeded by external tech does not take away from humans at all.

A parallel to this is a programmer that learns how to use a C++ compiler. They could go their whole career without ever understanding how the compiler itself is doing its job. I find myself wanting to learn how compilers work and started down this path. I look at the simple grammar I have learned to parse. Then I look at the C++ grammar and think "How can I ever learn to do that?" So I see us viewing potentially advanced things and wondering how the heck can we ever learn to do that. The common reaction when faced with such tech would be disbelief and in some cases ridiculing the messenger. When I was a kid the idea of sending a picture over a phone was laughable. Now this is common and expected. It was literally a scifi concept when I was a kid.

So, back to the alien tech. I am now thinking it would be cool to be working with alien technology through computing. This is like scifi stuff now! So what if what we have was not all invented here (Earth). If anything this will prepare us programmers to get jobs working for alien corporations writing ship level programs and brain interfaces. Think of it as intergalactic resume building. 😉

What software are you guys using that you recommend everyone should have? Anything from text editors to compilers to social apps. I just got a new laptop and I'm looking to get some nice software on it.

You know @otokolo reminded me of a gripe of mine regarding a doomsday fallback

Why has no one taken advantage of the considerable reduction in physical space required for storage and put a copy of Linux on ROM on a motherboard loaded with compilers and an ide ? Also why are these people so weird and cyclic? Was not originally that way and I don't remember enough up front to avoid it.
