Jeez. Maybe cool it for a while.

I’ve never felt the need for it and didn’t know what it was til just now. dd’ing image files to USB drives has worked fine for me.

Why another reddit competitor? There is already Lemmy.

Unihertz Tank 2? I sort of want one of those. The Doogee’s battery isn’t especially above average these days. The Motorola budget phone I use now has 5000 mah.

I’ve thought of configuring an Anduril light for just on/off. It is somewhat doable without reflashing.

Hard to see why to get this over a more mainstream phone where you can at least hope the software is not too flaky. Unihertz has some phones with special hardware features like tiny size or huge batteries. Doogee has had some of those phones but this one is just normal, 5100mah presumably non removable battery. Ok 20gb ram, but who cares? No price mentioned.

Doogee, make a phone with removable 18650s and I’ll pay attention. Or a phone that runs GrapheneOS out of the box, or anything interesting like that. This isn’t it.

Here’s a more informative article with a link to the paper, which is in a Chinese journal. The link doesn’t open for me rn but it’s a start.

I’ll see if I can try that stuff in the next few days but it’s my old phone that I don’t use much anymore.m, and I have some RL stuff going on. Thanks. Yes it is Android 7 for sure.

Thanks, that is helpful. Have you tried building from source on the desktop? Right now I’ve only used the fdroid apk’s. It works on one of my phones (Android 14) but not on the other (Android 7).

I spent a few minutes looking for the research paper, no luck. But it doesn’t sound like something to worry about for now. D-wave isn’t a general purpose quantum computer anyway. You can’t run anything like Grover search on it.

What are you working on and what kind of organization? Are you working with someone more senior? You could ask him or her for an assessment of where you should work on strengthening up.

You are in the right mindset if you are worried. Many C programmers greatly overestimate their ability to write bug-free or even valid (UB-free) code.

The AVR MCUs are pretty simple compared with 32 bit MCUs, so are good for asm coding.

Otherwise it’s a matter of coding til it’s reflexive.

Philip Koopman has written a book on MCU programming that sounds good. I haven’t seen it yet but someday. You might look for it: https://betterembsw.blogspot.com/2021/02/better-embedded-system-software-e-book.html?m=1

John Regehr’s blog is also good.

Is this the dog that was left tied to a pole in the hurricane? :(

Thanks, I see conversations on f-droid so will try it. I don’t see Dino there but that’s ok. I’ll look up what OEMO is.

XMPP does video chat, or at least voice? What clients do you recommend? Linux, android, and iphone are all of interest. Thanks.

In C in particular, you have to be very cognizant of the tricky ways the language can screw you with UB. You might want to try some verification tools like Frama-C, use UB sanitizers, enable all the compiler warnings and traps that you can, etc. Other than that, I think using too many obscure features of a language is an antipattern. Just stick with the idioms that you see in other code. Take reviewer comments on board, and write lots of code so you come to feel fluent.

Added: the MISRA C guidelines for embedded C tell you to stay with a relatively safe subset of the language. They are mostly wise, so you might want to use them.

Added: is your issue with C or with machine code? If you’re programming small MCUs, then yes, you should develop some familiarity with machine code and hardware level programming. That may also help you get more comfortable with C.

Were they better before?

Thanks yes I might look at the paper. Having a mixture of stable and chaotic regions is a well known phenomenon though. See for example Wada basins.

I thought this type of thing was well known in chaotic dynamics. There must be a new discovery here, but the phys.org article is not much help in explaining what it is.

Does termux not already do this?

Federation protocol is pretty simple and coding it could be a fun project for someone. Do you have software that you’d like to use? It seems like a good companion to a static site generator.
