Since I was little I was fascinated by club light shows I saw on TV shows. I just couldn't find out how they made light react to sound, which were two completely unrelated things to me back then. But I wasn't dumb and somehow figured out that if I hooked some low energy fairy lights to my amp and turned the bass up, they would lightup to the beat.
3 fried fairy lights and angry parents for to loud music later I swore to myself that I would someday build something that could light up my whole room and react to the music I was playing.
I started coding about the age 13 (turned 20 a month ago) with some old school bat scripts. But I wanted something that would generate a .exe so I googled and ended up installing Visual Studio Express (again angry parents for installing without asking) and started copying my first VB.Net program together. From there no one could stop me. I wanted to archive something with an application and googled until I found what I needed and learned to code this way.
I learned writing decent vb.net code and itvwas about this time I came into contact with IRC. I lurked arround there and this is were I came into contact with Linix servers, because I wanted to code IRC (eggdrop) bots, so I learned TCL and got used to Linux. Time passed and I ended uo being a Global OP on some network back then.
I did go further, coded Minecraft Mods, thus Java, changed back to C#, learned PHP and started setting things up on my VPS, Mails server, web server, etc.
Nowadays I work as a Systemadmin / Developer Hybrid, earning my first real money doing what I love to do and guess what? In the meantime I proved myself I can accomplish what I wanted as kid. I bought some Club LED DMX capital lights and programmed a controller for them which can control them in C#, but in a way I can run it on my raspi using mono. I also coded a client which runs on windows which uses some native libraries to calculate the dominant color of the shown picture in realtime (Handels 24fps 1080p) and uses the lights as ambient light, like you see them behind TVs sometimes.
The same app uses Bass.NET and an algorithm to dedect a beat in realtime and switches the light colors. Exactly what I wanted as akid, but better.
I can even control the lights via the new Google Assistant and/or Tasker.
Feels fcking good.
Some of my work lies on github among other, mostly trash: https://github.com/Kimmax - didn't updated there in a while tho.
I plan on writing a new free opensource plugin based modular home automatication server and pretty sure could use some helping hands..
I don't know why I wrote all this, just felt like it.
Also: first Rant
Please don't kill me for errors in the text, I'm to lazy to read through it again right now :P8 -
Been reviewing ALOT of client code and supplier’s lately. I just want to sit in the corner and cry.
Somewhere along the line the education system has failed a generation of software engineers.
I am an embedded c programmer, so I’m pretty low level but I have worked up and down and across the abstractions in the industry. The high level guys I think don’t make these same mistakes due to the stuff they learn in CS courses regarding OOD.. in reference how to properly architect software in a modular way.
I think it may be that too often the embedded software is written by EEs and not CEs, and due to their curriculum they lack good software architecture design.
Too often I will see huge functions with large blocks of copy pasted code with only difference being a variable name. All stuff that can be turned into tables and iterated thru so the function can be less than 20 lines long in the end which is like a 200% improvement when the function started out as 2000 lines because they decided to hard code everything and not let the code and processor do what it’s good at.
Arguments of performance are moot at this point, I’m well aware of constraints and this is not one of them that is affected.
The problem I have is the trying to take their code in and understand what’s its trying todo, and todo that you must scan up and down HUGE sections of the code, even 10k+ of line in one file because their design was not to even use multiple files!
Does their code function yes .. does it work? Yes.. the problem is readability, maintainability. Completely non existent.
I see it soo often I almost begin to second guess my self and think .. am I the crazy one here? No. And it’s not their fault, it’s the education system. They weren’t taught it so they think this is just what programmers do.. hugely mundane copy paste of words and change a little things here and there and done. NO actual software engineers architecture systems and write code in a way so they do it in the most laziest, way possible. Not how these folks do it.. it’s like all they know are if statements and switch statements and everything else is unneeded.. fuck structures and shit just hard code it all... explicitly write everything let’s not be smart about anything.
I know I’ve said it before but with covid and winning so much more buisness did to competition going under I never got around to doing my YouTube channel and web series of how I believe software should be taught across the board.. it’s more than just syntax it’s a way of thinking.. a specific way of architecting any software embedded or high level.
Anyway rant off had to get that off my chest, literally want to sit in the corner and cry this weekend at the horrible code I’m reviewing and it just constantly keeps happening. Over and over and over. The more people I bring on or acquire projects it’s like fuck me wtf is this shit!!! Take some pride in the code you write!16 -

Being a programmer in a scientific discipline can be infuriating.
using "no one" ="almost no one"
using everyone = "almost everyone"
1. No one knows what even the very idea of good practice is. And everyone refuses to learn. 3k lines of repetitive copy pasted main. 500 lines of plotting method.
2. Raw C-style pointer based array creation. Won't use develope array libraries because what if development stops. FUCKING HAVE YOU SEEN YOUR CODE WHAT IF DEVELOPMENT ON YOUR CODE STOPS. FUCK.
3. LOOP VARIABLES DECLARED AT THE BEGINNING OF THE METHOD WHY.
4. Everyone wants to make modular, independent code. No one wants to use OOP. NOPE. ALL IN ONE FILE. WRITE C++ LIKE A FUCKING PYTHON NOTEBOOK. FUCK.
5. LIBRARIES OH MY GOD PLEASE DO NOT CODE UP YOUR MATRIX MULTIPLICATION. PLEASE DO NOT TRIPLE LOOP IT. NO. THE LINEAR ALGEBRA LIBRARY WILL STAY IN DEVELOPMENT.
6. Please realize that literally not one comment over an 1800 line file does not help anyone.
FUCKING. WHY. WHY ARE WE SCIENTISTS SO GOOD AT SCIENCE AND SO FUCKING SHIT AT THE CODE THAT MAKES OUR SCIENCE HAPPEN. WHY. FUCKING. WHY. FUCK.undefined rage no comments scientific computing fuck this shit wall of text bad code science fuck c++ fucking4 -
As a pretty solid Angular dev getting thrown a react project over the fence by his PM I can say:
FUCK REACT!
It is nigh impossible to write well structured, readable, well modularized code with it and not twist your mind in recursion from "lift state up" and "rendercycle downwards only"
Try writing a modular modal as a modern function component with interchangeable children (passeable to the component as it should be) that uses portals and returns the result of the passed children components.
Closest I found to it is:
c o d e s a n d b o x.io/s/7w6mq72l2q
(and its a fucking nightmare logic wise and readability wise)
And also I still wouldn't know right of the bat how to get the result from the passed child components with all the oneway binding CLUSTERFUCK.
And even if you manage to there is no chance to do it async as it should be.
You HAVE to write a lot of "HTML" tags in the DOM that practically should not be anywhere but in async functions.
In Angular this is a breeze and works like a charm.
Its not even much gray matter to it...
I can´t comprehend how companies decide to write real big web apps with it.
They must be a MESS to maintain.
For a small "four components that show a counter and fetch user images" - OK.
But fo a big webapp with a big team etc. etc.?
Asking stuff about it on Stackoverflow I got edited unsolicited as fuck and downvoted as fuck in an instant.
Nobody explained anything or even cared to look at my Stackblitz.
Unsolicited edit, downvote, closevote and of they go - no help provided whatsoever.
Its completely fine if you don't have time to help strangers - but then at least do not stomp on beginners like that.
I immediately regretted asking a toxic community like this something that I genuinely seem to not understand. Wasn't SO about helping people?
I deleted my post there and won't be coming back and doing something productive there anytime soon.
Out of respect for my clients budget I'm now doing it the ugly react way and forget about my software architecture standards but as soon as I can I will advise switching to Angular.
If you made it here: WOW
Thank you for giving me a vent to let off some steam :)13 -
Did anyone heard about modular C?
I'm working on it at school, it's like how to do OOP in C with structures and function pointers.
We're developing the String class but next, we will make a basic C++ implementation in C before beginning the real C++
Do you think it's a good path?5 -
MENTORS - MY STORY (Part III)
The next mentor is my former boss in the previous company I worked.
3.- Manager DJ.
Soon after I joined the company, Manager E.A. left and it was crushing. The next in line joined as a temporal replacement; he was no good.
Like a year later, they hired Manager DJ, a bit older than EA, huge experience with international companies and a a very smart person.
His most valuable characteristic? His ability to listen. He would let you speak and explain everything and he would be there, listening and learning from you.
That humility was impressive for me, because this guy had a lot of experience, yes, but he understood that he was the new guy and he needed to learn what was the current scenario before he could twist anything. Impressive.
We bonded because I was technical lead of one of the dev teams, and he trusted me which I value a lot. He'd ask me my opinion from time to time regarding important decisions. Even if he wouldn't take my advice, he valued the opinion of the developers and that made me trust him a lot.
From him I learned that, no matter how much experience you have in one field, you can always learn from others and if you're new, the best you can do is sit silently and listen, waiting for your moment to step up when necessary, and that could take weeks or months.
The other thing I learned from him was courage.
See, we were a company A formed of the join of three other companies (a, b, c) and we were part of a major group of companies (P)
(a, b and c) used the enterprise system we developed, but internally the system was a bit chaotic, lots of bad practices and very unstable. But it was like that because those were the rules set by company P.
DJ talked to me
- DJ: Hey, what do you think we should do to fix all the problems we have?
- Me: Well, if it were up to me, we'd apply a complete refactoring of the system. Re-engineering the core and reconstruct all modules using a modular structure. It's A LOT of work, A LOT, but it'd be the way.
- DJ: ...
- DJ: What about the guidelines of P?
- Me: Those guidelines are obsolete, and we'd probably go against them. I know it's crazy but you asked me.
Some time later, we talked about it again, and again, and again until one day.
- DJ: Let's do it. Take these 4 developers with you, I rented other office away from here so nobody will bother you with anything else, this will be a semi-secret project. Present me a methodology plan, and a rough estimation. Let's work with weekly advances, and if in three months we have something good, we continue that road, tear everything apart and implement the solution you guys develop.
- Me: Really? That's impressive! What about P?
- DJ: I'll handle them.
The guy would battle to defend us and our work. And we were extremely motivated. We did revolutionize the development processes we had. We reconstructed the entire system and the results were excellent.
I left the company when we were in the last quarter of the development but I'm proud because they're still using our solution and even P took our approach.
Having the courage of going against everyone in order to do the right thing and to do things right was an impressive demonstration of self confidence, intelligence and balls.
DJ and I talk every now and then. I appreciate him a lot.
Thank you DJ for your lessons and your trust.

I'm a big fan of super-modular and flexible code, but my colleagues are huge fans of Ctrl-C / Ctrl-V.1

I've spent a lot of time messing around with C, having struggled with object-oriented programming (due to not really knowing how best to structure things, not knowing when to apply certain design patterns).
When writing C code, I'd write OOP-esque code (pass around a struct to routines to do things with it) and enjoyed just making things happen without having to think too much about the overall design. But then I'd crave being able to use namespaces, and think about how the code would be tidier if I used exceptions instead of having every routine return an error code...
Working with Python and Node over the past couple of years has allowed me to easily get into OOP (no separate declaration/definition, loose typing etc.) and from that I've made some fairly good design decisions. I'd implemented a few design patterns without even realising which patterns they were - later reading up on them and thinking "hey, that's what I used earlier!"
I've also had a bit of an obsession with small executable files - using templates and other features of C++ add some bloat (on Windows at least) compared to C. There were other gripes I had with C++, mostly to do with making things modular (dynamic linking etc.) but really it's irrelevant/unreasonable.
And yes, for someone who doesn't like code bloat, working with Node is somewhat ironic... (hello, node_modules...)
So today I decided to revisit C++ and dust off my old copy of C++ in a Nutshell, and try to see if I could write some code to do things that I struggled with before. One nice thing is that this book was printed in 2003, yet all of its content is still relevant. Of course, there are newer C++ standards, but I can happily just hack away and avoid using anything that has been deprecated.
One thing I've always avoided is dynamic_cast because every time I read about it, I read that "it's slow". So I just tried to work around it when really if it's the right tool for the job, I might as well use it... It's really useful!
Anyway, now I've typed all this positivity about C++ I will probably find a little later on that I hit a wall with what I'm doing and give up again... :p7 -
Modular C is a mess to get to work. It looks really great but it takes sooo looong to make it work...
How do people deal with it?1 -
Lets talk about our dream phone!
Here's what mine would be...
Screen: 1440p AMOLED highly saturated screen.
CPU: Snapdragon 845 (Or whatever is on top)
RAM: 4-6 GB
Storage: 16 GB internal OS reserved storage for the OS only but on the side would have 2 slots with the same locking mechanism as the sim tray to hold 2 hot swapable storage or battery modules.
OS: A modular version of stock android (By modular i mean a version of stock android that is designed to be installed on any device)
Speaker: Dual front facing stereo
Ports: 2 usb-c ports on the bottom.
Special features: A portable desktop experience that when plugged into a monitor would give a chromeOS style experience with the phone acting as a touchpad.7 -
hmmmmmm let me see.
Web based? lets do web based.
Do something simple like a basic crud app on web api format:
Do it with full authorization and authentication.
Start hard. Do it with pure golang using NOTHING but the std libraries.
Now, do it in a magic mvc framework like Rails or Laravel
Now do it on dotnet core
Now do it in django rest.
Watch the differences in all of them, sell your soul to something and now do it in Clojure. If you do it on a Scheme dialect or on Common Lisp my CMS admin will suck your whatever you have. Dude seems to be pretty good at it, we are trying to keep him from pulling tricks on the street but he insists.
Then add a React client with Typescript to get them basic ass endpoints to display nicely.
It should give you a fuckload of perspective amongst the different tools and way we do things and might make you appreciate the differences in paradigms required(pro points for doing modular in c# dotnetcore using different classlibs for the major points of the application using some crazy pattern like the mediator pattern)
I would hire a mfker that throws all this shit at me on a portfolio on the spot.10 -
Any other language: Hey fuckface, you can't name this variable by a single letter, tf is wrong with you? use some descriptive shit.
Golang: lmao fuck u
I really find it interesting how we use short variable names for items in golang. Kinda makes sense when you think of it. Most of these items come up in short methods for which the mental model lets you know and remember what you are doing, they even make sense when going through the std lib in which that shit is all over the place. YET years of going by other languages has made me squint my eyes a bit in frustration every time I see it.
Say for example that a function is implementing io.Writer. What would you call the method parameter? you could argue that writer would be sensible since it has it in the signature, but what about when the io.Writer in itself is a file or a socket or whatever? writer would be funny or strange? nah fuck it just w, it makes sense, but x wouldn't. I find these points to make sense even if i don't like them.
Would, now, this practice be acceptable in C? you are supposed to write the same modular code with C in which you compose large functionality in separated units of code, yet I am sure this practice of single name variables is something that C engineers dislike greatly.
Are go devs just doing this out of blind love for their preference in languages? and how would this work if mfkers add generics to go(I hope not, Go is simple enough to understand in order to extend functionality through the empty interface, but that is a preference of mine as well)
The more I use Go the more I like it to be honest, I think the code looks ugly syntactically, but that is subjective as all hell and based on my constant preference for a language to look like Ruby, which even though it might not be everyone's cup of tea it remains to my eyes as the most beautiful language in existence, again, an obvious personal preference.18 -
I legit never understood the hate for VB.NET in the land of Microsoft development. To be entirely fair, I only used it it that one class at uni. But other than that I had never used it in the real world. The closest thing I had done with BASIC was VBScript, and even tho I was ok with it(even liked it) I damn well know that it is not something that I would use to build web apps with anymore.
But I am inclined to give VB.NET a chance only because I remember being able to make sense of my peers code in school. Just by reading it, sure it might be verbose as all fucking hell, but we were using VS(notice that i said VS not VS Code) and we had all the bells and whistles of autocomplete and intellisense.
Currently tho, I somewhat wanted to try a more modular approach to my fucking around with web apps, we are considering Rails and Django for a project at work. But since we already have windows servers we thought about the possibility of using .net core. We all like C# as a language and I did work with ASP.NET MVC before so we are considering that as well. That and our sys admin had tons of experience setting that as an environment. When developers are not too sure it is good to rely on the admin's expertise. -
Do you guys think I should go for a Lego Mindstorms set as a way to start getting into robotics?
I know of a lot of people that recommend going through arduino and buying a bunch of shit and throwing it together etc. But the thing that makes me interested in Mindstorms is how everything seems to be in one place. A smart brick programmable through multiple different programming languages(for example Python, java, C) a good kit that can be really modular and built into different components, all sorts of sensors.
I just think its a good option, but if someone were to recommend a particular book or resource for Arduino or some other stuff I would definitely consider it.
So, what do you lads think?14
