Happy to see this futzing around on a JH7110 based board! :-) Because this SoC is used on 3 boards that I'm aware of: StarFive VisionFive 2 Star64 Milk-V Mars (please add if I missed any) All friendly priced, similar specced

> As a developer, I'm fine with 3 years of support, security or otherwise. There's the problem: developers primarily think of themselves, expecting end users to be power users not unlike developers. That doesn't hold. Deve

Some options that popped onto my radar recently: Allwinner F133 Bouffalo Lab BL808 GreenWaves GAP8 (no native video hw on this one I think? targeted at IoT edge computing) Surely there are more (or will be :-). Problem is usual

I've never cared much for consoles due to their "walled garden" aspect (not user-programmable, locked down hw & sw). PC, 80's/90's home computers: programming bits & pieces Lego style by oneself, exchan

Yeah I'd like something like that: * 'Many'-core CPU (say 8..16 relatively simple cores, eg. RISC-V) * A good, but modest amount of RAM (eg. few dozen... few hundred MB) * Integrated graphics, but of a conceptually simple t

I would wager a guess that in most (if not all) of those countries, a relatively large % of children die young. That is: population growth in those countries could be much less than fertility rates suggest. Whether that situation improves,

It is survival of the species that counts, and the 'geological' timescales over which it does. Some individuals from that species reproducing is obviously a requirement - but only as a means to an end. Whether individuals re

Nice project indeed. Just 1 nitpick - all vintage parts, and then a PIC uC just to generate a clock & reset? Grr.. ;-) > And this, ladies and gentlemen, is why we validate our Supply Chain :-) I've got a nice collection of vinta

Good read! I'm not even going to summarize... If humanity's impact on this planet interests you at all, then please read the article. Let's hope the ever-more-pressing state of affairs causes short-sighted politics to leave

Well there's the "steer a beam across a screen" as used in CRT's (eg. older oscilloscopes) and the Vectrex game console. Maybe one could consider lasershows falling in this category too? See "vector display"

Better yet, able to check what this site is about. Somehow the page stuck at "I'n not a robot" recaptcha thingie. No action beyond that -> whatever site did or showed, it did NOT do or show in my case. And therefore wasted

Grey-haired, mostly white, male, economy-focussed politicians running the show, revolving door between multinationals (including Big Oil) and those politics... Is it any surprise so little was done over the past decades? They won't fix

Just below the title (on YT page) it says "...more". Click / tap on that to expand into a summary. Imho: out-of-control capitalism, and the resulting wealth inequality with all its negative effects. Ok, the world obviously is

In general, countries that rank high in this index, are countries that "work well" with the 'community of nations'. Regardless how one may feel about that. In my case (Dutch passport): the Netherlands is a member of man
