…I probably should have checked the byline before posting. It does still come from the same material, just a little more directly.

There’s some weirdness on that because she did some important but not-very-public work at IBM in the 60s with their ACS/“Project Y” effort that did what we later call superscalar/multi-issue processors like …20 years before those terms existed. As part of that she wrote a paper about “Dynamic Instruction Scheduling” in 1966 under her pre-transition identity that is a like retroactive first cause for a bunch of computer architecture ideas.

There was almost nothing about that work in public until Mark Smotherman was doing some history of computing work in the late 90s, put out a call for information about it, and she produced a huge trove of insider information after deciding it was worth exposing the provenance. There’s a neat long-form LATimes piece about the situation which is probably the primary source for the history in OP’s link.

Neat.

I set up some basic compute stuff with the ROCm stack on a 6900HX-based mini computer the other week (mostly to see if it was possible as there are some image processing workloads a colleague was hoping to accelerate on a similar host) and noticed that the docs occasionally pretend you could use GTT dynamicly allocated memory for compute tasks, but there was no evidence of it ever having worked for anyone.

That machine had flexible firmware and 64GB of RAM stuffed in it so I just shuffled the boot time allocation in the EFI to give 8GB to the GPU to make it work, but it’s not elegant.

It’s also pretty clumsy to actually make things run, lot of “set the magic environment variable because the tool chain will mis-detect the architecture of your unsupported card” and “Inject this wall of text into your CMake list to override libraries with our cooked versions” to make things work. Then it performs like an old GTX1060, which is on one hand impressive for an integrated part in a fairly low wattage machine, and on the other hand is competing with a low-mid range card from 2016.

Pretty on brand really, they’ve been fucking up their compute stack since before any other vendor was doing the GPGPU thing (abandoning CTM for Stream in like a year).

I think the OpenMP situation was the least jank of the ways I tried getting something to offload on an APU, but it was also one of the later attempts so maybe I was just getting used to it’s shit.

Don’t trust that they’re 100% compatible with mainline Linux, ChromeOS carries some weird patches and proprietary stuff up-stack.

I have a little Dell Chromebook 11 3189 that I did the Mr.Chromebox Coreboot + Linux thing on, a couple years ago I couldn’t get the (weird i2c) input devices to work right, that has since been fixed in upstream coreboot tables and/or Linux but (as of a couple months ago) still don’t play nice with smaller alternative OSes like NetBSD or a Haiku nightly.

The Audio situation is technically functional but still a little rough, the way the codec in bay/cherry trail devices is half chipset half external occasionally leads to the audio configuration crapping itself in ways that take some patience and/or expertise to deal with (Why do I suddenly have 20 inoperable sound cards in my pulse audio settings?).

This particular machine also does some goofy bullshit with 2 IMUs in the halves instead of a fold-back sensor, so the rotation/folding stuff via iio sensors is a little quirky.

But, they absolutely are fun, cheap hacker toys that are generally easy targets.

Sure, drop me a note with the details and I’ll see if I can give you a hand. I’m not super expert in all the specifics of the Chromebook ecosystem, but I have good general computer/Unix skills and have hacked a couple so I know where to look for resources.

Relevant place to ask: I’ve been trying to find a reference for the earliest Emacs that could host a terminal emulator or subshell in a window.

Multics emacs appears to have had both split windows and a character-at-a-time input and output mode as far back as 1978 for use as a SUPDUP and/or TELNET client, which is currently the earliest I’m aware of. Ancient ITS TECO EMACS had splits pretty early on, and may have sprung the necessary character plumbing earlier - but I’ve never found any reference material to confirm/deny.

It’s a fringe to a larger interest, which is that I’ve been trying to document the history of terminal multiplexers, especially in the Window (1986)-Screen(1987)-Tmux(2007) tradition (as opposed to the historical meaning which we’d call terminal servers). I’m slowly becoming convinced they came about after the advent of floating window GUIs hosting multiple terminal emulators. If you were super connected and could get access to one, sometime fairly early in the window between the 1973 introduction of the Alto and the surviving 1979 manuals the Alto program “Chat” could run multiple telnet sessions in floating windows (I’m also looking for a more precise date for when Bob Sproull made Chat able to do that trick). Several other early graphical systems like Blit terminals (1982 inside Bell, commercial as the 5620 in 1984) and early Sun Windowing System of early SunOS (1983) could also do multiple floating terminal emulators, so they were common by the early 80s.

Because the 36-bit DEC lineage had pretty robust psuedoterminals all the way back into the mid 1960s ref, a lot of hackers did a lot of fun shit on PDP-10s with ITS and TENEX and WAITS, and Stanford and MIT had PDP-10s connected to fancy video terminals by the mid 70s, it’s IMO the most likely place for the first terminal multiplexers to emerge… if I could just find some documentation or dated code or accounts.

Most Chromebook’s firmware is Coreboot, but it’s running a Depthcharge payload instead of UEFI (or BIOS or whatever). Mr. Chromebox maintains UEFI Coreboot payloads and install tools for a wide variety of (x86) Chromebooks, which can be used to flash a normal UEFI payload and boot normal OSes. It’s strictly possible to boot normal Linux systems on a the Depthcharge payload modern Chromebooks use, but uh… here’s the gentoo wiki on it, it’s a substantial pain in the ass.

The only commercial Android game I regularly play is Wordscapes. It’s an almost embarrassing level of enduring basic bitch addiction, I don’t engage with any microtransaction bait, I have a systemwide ad blocker… and I love it.

Otherwise it’s all Emulators and Open Source (covered well elsewhere in this thread).

Oh, it is, I just meant my instance has had its keys rebound so I haven’t run into that problem.

When last I looked miniflux wasn’t quite as featured a solution as I’m looking for (I keep a lot of notes and such embedded in my DB), but it is pleasingly simple.

Ah, I’ve had the googlereaderkeys plugin enabled forever so I don’t even know what their default keybinds are. Unless I see something super compelling (or a serious problem with tt-rss and its ecosystem) I’m unlikely to change, but I like to keep my ear to the ground on the space.

Since you’ve used both, what are your feelings on FreshRSS vs. tt-rss?

Around the death of google reader, I set up a tt-rss instance, imported all my saved stuff, and I’ve been using it continuously since (I’m technically in an unsupported configuration because I set it up long before docker became the preferred then only supported configuration, but it just keeps ticking installed like a normal piece of software on a rented VM).
I’m generally super pleased, and it’s my primary mode of content consumption via browser + Android App, and I use the “note” and “share with note” features pretty extensively to plumb to some other folks with similar setups.

Fox (the main tt-rss dev) is clearly an asshole, and there are some geopolitical complications because he’s a Russian national, but he’s made an excellent focused piece of software. I’ve considered looking seriously in to FreshRSS, but have a lot of inertia and at a glance it looks like it’s missing a few features.
