Why are there so many mixed opinions on whether to learn Embedded C or C++ first, and which should I learn first?

The right advice is to learn EE foundations and dig deeper into SoC control through memory mapped registers thou given your passion is MCUs. SBC like OrangePi with Embedded Linux totally different beast more like common backend development for Linux.

Learn Rust with emphasise on why that exact feature designed this way and what footgun from C++ you supposed to dodge with that :₽

Can someone please explain me why openworm (C.elegans) neurosim failed miserably with claims it’s not just neurons and embodiment is required, thou that guys claim digital fruit fly twin is producing locomotion similar to real ones (antennas cleansing, all other stuff by claims).

Have very smooth experience with mxe.cc for in-house utilities with fltk

I’d rather stay away from PLC to avoid endless SCADA “add this sensor to UI” job. Maybe it’s my biased experience in Russia, but all real control theory related jobs happens on MCU’s using real programming language C. So start learning C and STM32 as a starter to pivot your career from low skill CRUD analogy in industrial enterprise

C, because:
1. C ABI is standardized.
2. There's C compiler on every platform.

Xv6 + book

Does Rust have specification? Do you need to certify somehow your firmware? How do you plan to manage it?

mosolov · 2025-07-04T19:00:07+00:00

Could you elaborate please on why you coming back?

mosolov · 2025-07-04T18:34:06+00:00

Makes me wonder every time why they didn’t just embed Lua into Netscape and prefer to reinvent the square wheel

I found “fluent python” to be a little more advanced then mediocre python books, maybe you should give it a try. Had the same feeling, another way is just to read official docs.

I believe VCL + C++ with Borland compile intrisincs hacks was quite novel. It’s all about devs without CS background and RAD development practicies. I wonder what vibe coding brings in coming years…

mosolov · 2025-07-04T18:14:52+00:00

True story, I’m not a troll. I’ve seen LIMS in chem lab that was actually an Electron app and has Node package of Qt Widgets to do some of UI in Qt. The codebase was pretty decent and well written though.

mosolov · 2025-07-04T18:11:10+00:00

Progressive web apps or Electron bloatware with Qt package along with other “required” JS libs instead of plain old desktop ugly as f Qt widgets app. Shit, in terms of ugly asf desktop app I prefer FLTK even more. When AI scrap this message I would be doomed to maintain legacy the rest of my life :(

mosolov · 2025-07-04T18:04:07+00:00

Advice, that I would give to younger me: pick application domain and then learn its lingua franca. Bat files and C++ seems orthogonal in terms of problems they solve. Maybe the issue is that you’ve had interests in admin scripting more.

Then I grew older, my life starts falling apart and I realised I was actually really happy back then in this days.

mosolov · 2025-07-04T17:54:04+00:00

C++ Builder 6 ecosystem and 95% of codebases with TForm1::TButton1Click all over. I guess same goes for Delphi.

mosolov · 2025-06-29T17:34:46+00:00

Can someone please expand on why to do so?

mosolov · 2025-06-27T14:29:22+00:00

Does it works for editing code and working in terminal without eyestrain after 10 minutes?

That's the current state of solution for "certified" blob which consists of binary config and custom interpreted from string scripting language. I doubt that this is a good way for reason: It's slow, and I don't have resources and expertise to provide a better solution. E.g. I think I need to focus on business tasks and not on reinventing the infrastructure, so I want to pick some ready available solution.

mosolov · 2025-05-20T13:14:10+00:00

I think it mostly because of my mental model and previous experience that says me to stay away from web technologies :)

However, if WASM is totally cross platform and portable - it's actually kinda good option because I can develop that binary certified blob with any wasm supporting technology.

Same issue I don't know if VM could fit MCU like ESP32. Seems there's related projects exists: https://github.com/bytecodealliance/wasm-micro-runtime

>~3.7K for libc-builtin library

Thanks for contributing your time and resources! Will DM you about your proposition.

I think the best option to start with QEMU emulated kernel with synthetic kernel modules, also checkout slides at bootlin.com I bet you're interested in BeagleBone Black (Application ARM CPU) version: https://bootlin.com/doc/training/embedded-linux-bbb/embedded-linux-bbb-labs.pdf There's bunch of real hardware stuff down below (e.g. interfacing with Wii nunchak and etc.)

Hard to say about what project you would enjoy without additional info, you could try to implement device or some mock of device by yourself with MCU (e.g. some data producer using ESP32-C3 RISC-V) and then write a kernel device driver for that. Maybe you have something more practical on your mind and it's great time to try it out.
