Thanks! Since I am still waiting for RP2350 availability I am working on video edit for VGA and FPGA extension.

Thanks, keeping fingers crossed for your project !

Thanks, new episodes are under recording. Hopefully I will release them soon!

Thanks!

Thanks!

My goal was to show all steps of the project, but then I realized that it is hard to follow. I hope some day I will find the balance between what to show and what to cut :)

Yeah, that's true, that new videos are much shorter.

Good to know. Latest videos use spectrum filtering to remove voice frequencies inside music. That one unfortunately does not use that yet.

I am glad I helped you. In my experience I realized that almost all concepts are quite simple, even if they look complex.

Writing a filesystem from scratch is also interesting. But for now I have to use something already existing.

That was one of the main goals when I decided to start my RU-vid :) Use it whatever you want :)

Yeah, I wanted to show all the steps of the project lifecycle ( except maintenance, since it's too early ) :)

Thanks! I am trying :)

Thanks !

To be honest, me too. C can't be substituted in some environments. But whenever it could be I think it should be. I mostly use C++, but I am looking for tools that can improve or even replace it into safer language transpilers ( like cppfront ), where other compilers like (i.e rust are not fitting). But I really hope that the standardization committee will resolve most of the problems some day.

No Code, No Problems! :)

That's always true :)

Yes, but it uses more than that :)

Thanks! I've noticed that, although I am still working on improving the readability of my videos new ones should be at least a little bit better.

Thanks :) currently I am working on adding PIO simulation for the next part. I think I will release a video on how to use it on other projects. Of course it still will be in work in progress mode with contributions warmly welcome :) in which environment have you tried to implement RP2040?

​@@matgla95 to be clear - by implementing I meant Renode implementation. I'm more focused on other MCU series right now ;) looking forward to see the video on how to use Renode. Maybe I'll learn something new from it :D

In thumbnail? At my computer's PCB.

So, let me clarify a little bit. The code is on SPOJ and is executed for 10 test cases. Test data is provided on STDIN in the form: 1 <- test case 1, n = 1 8 <- test case 2, n = 8 ... rest 8 test cases. Your code should output answers on STDOUT separated by whitespace for each of such test cases. According to segmentation fault. I see two problems in the code that you wrote; scanf in the original code reads a decimal number from STDIN in storing it in the k variable; thus, scanf("%d," &k), otherwise k is uninitialized and scanf depending on libC implementation may segfault, it thinks it has one argument according to format string, but it's not placed in argument list and is writing data to some unexpected memory address (most probably null). Additionally, there is '~' before scanf to detect EOF. Otherwise, the program will not end.

I think beauty is subjective and depends on context. Here I used it a little bit ironically, since you can still do things that should not be allowed, at least by default. Hopefully compilers are evolving and, i.e. GCC 14 rejects such code by default which is good in my opinion!

Thanks, for that comment! That software is created mainly for educational purposes. I don't think that I will be able to create OS/Bootloader/(What ever else) that is able to compete with any other not single person project. Also I don't see any real usecases to run it over network. It's closely related to specific hardware. For other cases there are better tools available. But if someone will find a way to use it: good for him! :) I selected GPL for software, because I like that part you have to share with community if you wanna use it. But I wasn't digging deep through all licenses availble, I just selected first one that was fine for me. AGPL also fits, but I don't think I will change all license headers right now. About hardware part, it's an experiment. I am only hobbiyst, so I decided to publish with just MIT. Basically to allow anyone to do whatever they want with that.

@@matgla95 One of the good things about the GNU AGPL is that the network use is redistribution clause doesn't really apply if you do not make the software available over a computer network. In that sense it is pretty much identical to the GPL for non networked software, but if anyone turns it into a service as a software substitute then the network use is redistribution clause kicks in immediately.

Thanks! :)

Sure! Good point and that one is even reported by GCC, when using the -Wall flag :) but the goal of that exercise is to abuse whatever you can in the provided compiler to achieve the smallest possible source code

Thanks!

Originally that code doesn't contain . It was added just to better presentation of execution. The testing from SPOJ is executed for many inputs from stdio and space is necessary to separate outputs for test cases.

Thanks :)

Thanks!

Yup, different languages due to different paradigms enforce to improve the skill set and it seems you have a win-win outcome :)

Yes you're right, I have a problem with recording on Linux ( my camera interface produces crazy delays, most probably Nvidia again broke their driver xd ) which I haven't solved yet, so I temporarily switched to windows.

@@matgla95 That's no excuse to have it running in the background. Honestly, I'd be embarrassed. You do you though. I'm sure your excuses will safe you from the social credit system you help implement by running spyware. Oh, and don't get me started on the smart phone which I'm pretty sure you have too.

No no, I am only using pigeon post :)

@@matgla95 You sound like a smoker telling me that smoked meat takes longer to go bad. I guess the copium is always real. Anyway, you keep making excuses for being the corporations' female canine. Another thing though. Are you actually in Poland? We are always looking for Team Fortress people in Europe. I wrote a fork of the original for the Darkplaces engine with more emphasis on tactics and stealth.

It just performs bitwise negation on value returned from scanf function to break loop when got EOF ( which normally is -1 ).

thanks, It's even worse when types promotion come to case when you have different type sizes on different platforms.

stdint.h... Anyone not using them is just stupid or has an old codebase.

Ah yes, because we sure do love writing non portable code! are we forgetting about the fact that C is a systems language? if you need code specific to a certain platform, then use stdint.h types, if you need portable code that works between platforms where you don't know what the width will be, then use standard integer types. I thought this was figured out like 50 years ago, we can't have devolved that much, right...?

@@tiranito2834 why should normal ints be more portable? There is no real point in using normal ints over standard int. Platform dependent types are only necessary for system level interfaces and working with pointers. And in most cases the explicitly platform dependent size_t is all you need. Having the possibility that your int might be "arbitrarily" long depending on the platform might even cause bugs in form of unexpected integer overflow or compile errors in case of to large literals. Tldr always use stdint.h if possible. It makes the code more stable and compatible and portable.

Yes, Rust/C++ require a lot of time invest. They are really hard to master, but still you can write good code without mastering each piece of a particular language.

very thanks, greatings saludos desde Bolivia, querido amigo.

There are better languages for backend

@@unknownguywholovespizza For the niche I am aspiring to, they are the fastest and what I need to learn. Thanks for your comment, greetings

Thanks! let's do it! Keeping fingers crossed!

Sure, pl.spoj.com/problems/SUMAN/ And more exercises and challenges like this are here: www.spoj.com/

@@matgla95 I have a 52 letter solution but how do I make it use the correct compiler :c

And that was one of the reasons that I decided to publish that video :) it's an old challenge and the current solution is easy on the internet to find, so I hoped someone will try to reduce it more! Unfortunately since the whole website is old and I am not even sure it is maintained, the latest compilers are not available.

I lied, I misscounted, sorry for my ignorance :D

@@CodingWithDox I am glad you tried. Someday someone for sure will find a better solution :)

I always recommend doing actual programs instead of courses. To be honest I almost always boycott most of course, it's too boring for me instead I am using them as a "what to learn next" list. Then think about what program you could wanna write and try to do it. It won't be perfect for the first time, but you can gain real experience and continuously improve it. It could be big or many small ones, but always think how you can improve them after all. When I was taking part in interviews in my previous company always the best candidates were with people that came with projects on GitHub that they prepared by themselves and it was easier for them to adapt to project.

@@matgla95 very thanks 🙏🏻

@@matgla95 Let's say I want to learn how like you, where would I start, if there is a lot of information, like the basics without having to go through the courses, the githubs are huge and there are topics in a single repository of different things, the documentation is technical and difficult, as you did at the beginning to later be able to extricate yourself from c, this answer would help me a lot more. greetings

I don't mean to completely drop courses, they are necessary to learn basics. I also started with a course something like " from zero to games coder". And with each exercise I did a similar one on my own. Like it was a random number generation section with exercise with solution, so I did it, but then wrote my own program that also uses random number generation. With some basics I started writing game, since it was fun for me, step by step. With no knowledge it required a lot of internet research, like the first goal: select library, then render black window in OS... Trying to move from courses to reading reference manuals for language and documentation for libraries. Today all those GPT/Copilot could help to speed up information searching on given topic. Starting you may want to write as much as possible on your own, it's reinventing a wheel, but needed if you want to get deep knowledge. But most important is to find a way of learning that makes you fun. If it's not fun most probably you won't be able to spend enough time to grow fast, so the whole road will be longer. Keeping fingers crossed :) Which language you are trying to learn?

@@matgla95 I've been trying to learn Rust for months, I took courses and read books but I haven't made any progress, I feel stuck, my goal with Rust is the backend, even in the same book it tells you that before that you must know C++. My biggest dream is to master Rust and then C++. that's why I started following your channe

Dziękuję! Regularność niestety aktualnie nie wchodzi w grę, choć marzy mi się przyspieszenie montażu (pewnie kwestia wprawy). Kanał rozwijam w swoim wolnym czasie, a do tego dopiero uczę się nagrywania i montażu :) Póki co wystarczy lajk lub miłe słowo :)

Thanks! You can try my videos, but the first ones are far from perfect. I am still learning about video creation.

Imagine my face when I found that type is not needed in the main function argument :)

Hi! I was teaching myself around 16 years ago. Back then I was using some random c++ course in my native language. I think most important is to spend a lot of time doing exercises. Starting from basics means firstly you need to learn the programmer's way of thinking and problem solving starting from really basic and simple programs. C++ is quite a complex language to learn, but patience and consistency will pay off in the future.

That's only my personal opinion and to say it loud: I have no Rust experience, only years of experience in c++. I did some research that made me think that using Rust it's harder to write unsafe code in some areas ( i.e. memory safety, thread safety ) as opposed to C++. But still in any language you can write unsafe code and in any language you can write safe code (even in assembly or brainf**k, but with more effort spent and easier to introduce buggy unsafe code by mistake). And that covers just language level safety. I think that a much harder point is to implement the whole software architecture as a safe which is more crucial. Maybe we have someone here with both C++ and Rust experience? I am curious about her/his view :)

Thanks! I am working on the next videos. But it will take a while due to limited free time :)

Yes, maybe a little bit too loud. Thanks for the comment!

Thanks! If you like that topic there are also 2 next parts available on my channel with evolution from dynamic loader to dynamic linker.

Thanks! I am glad I am progressing :)

Thanks! I hope you enjoyed:)

Hi, lovely to welcome you. Each kind of support is a huge boost, not just a little. Big Thanks!

Hi, glad to see you. I hope you enjoyed it and each next episode will be more and more interesting for you.

Thanks, I hope you enjoyed it!

Słuszne spostrzeżenie. Zwrócę na to uwagę i postaram się, żeby zacząć to wymawiać poprawnie. Mam nadzieję, że w kolejnym odcinku już nie będzie występować ( oraz kilka innych problemów z wymowa i gramatyka :d ). Dzięki!
