@ChronRevisited @lori I like this chart from ZX81 manual.

@lanodan @niconiconi have you tried compiling new WebKit with old gcc+glibc or old WebKit with new gcc+musl? ;P

@pixel what are you going to eat when you are hungry and there's no leftover crumbles in your keyboard?

In the aftermath of CollapseOS email list drama, I wrote a note about healthy conversations in diverse communities: https://www.ninakalinina.com/notes/conv.htmlI tried to summarise the things about the topic that I've learned in the last few years. Maybe they will be helpful for you, too.

@niconiconi people writing C/C++ programs with source files longer than a few screens should be sentenced to porting their code to BSD running on Motorola 68k. FWIW, this experience helped me to understand why long source files are a bad idea.

@littlefox @niconiconi ez: compilation takes a lot of time on smaller machines. If you have compilation errors, it's much faster to fix them in small files (10-20 seconds per file) than waiting for a compiler to fail on a large file (which can take minutes)

I was curious what they put in phone wall plugs these days.ARM, of course.Some have more than one.

Think about it, there's enough might to run Doom (and probably Quake) on it, with enough to spare to have USB keyboard, mouse, storage and a display over GPIO. Insane.

@whitequark I also heard that USB-C implementation is a major pain, so it doesn't make sense to put an 8051 core next to a huge USB-C PD layer implementation. So, it is not gratuitous in a sense of "being up for the task".It's the task that is, at least a tiny bit, crazy. I mean, if a power source needs a CPU faster than 68030, what kind of computing are we expecting to do with the computer we are powering up?

@whitequark I was talking about this part of the USB PD hardware. I don't see any problems with a modern 48 MHz 8051 clone to handle the protocol itself (and apparently there are USB PD controllers based on 8051)

@niconiconi @whitequark I heard USB PD is a formidable foe that left many engineers heartbroken. But Sonix SNPD1710 can do USB PD 3.1 on a 8051 with just 1.25 kB RAM

Here's some more scary things to think about.Most of the devices that have at least a blinking LED and were manufactured in the last 15-20 years are about to start breaking down. That's because most microcontrollers and FPGAs manufactured since 00s are using memory types that guaranteed to live only for 5-20 years.In the days long gone, mass-manufactured devices with digital logic tended to use mask ROMs or antifuse ROMs. That made the devices cheap, and the data stored to boot them could last almost forever.But erasable programmable ROMs, and later Flash, became cheaper and more popular. They have benefits of being (somewhat) re-programmable, unified, easy to use, and so on. The data retention for Flash-based devices (reprogrammable FPGAs and microcontrollers) is ±5 years. Those that use EPROM (pretending to be one-time programmable ROM) can last for 10-20 years.Alternatives exist, but rare.How do I sleep now?

Naturally, it means Switch cartridges won't last over 20 years.** Correction: they are rated for 20 years at 85C. So, they should last more, in theory

@adam wait, what do you mean by "centralised internet access"? Isn't internet made out of small patches of various providers?

#chip_scavenger adventures! @yottatsa and I found a discarded toy car while returning from a bicycle ride. It had good lead batteries, very lame electric motors, a motor and charge controller, and, most interestingly, a built-in MP3 player with TF card, USB and FM radio. As far as I can tell, the main chip is a relative of a ZHUHAI JIELI AC69, which is a pi32 architecture. @whitequark mentioned on Twitter that this series of chips (pi32) seems to be an OpenRISC fork. Also, questions for Catherine: 1) It seems they aren't cryptid CPUs, they're everywhere in cheap bluetooth speakers and such, what do you think?2) Wanna play with one?
