RE: https://mastodon.social/@pojntfx/117315519904062912 I do hear plenty of criticism and skepticism even in IRL non-nerdy interactions buuuut, yes, holy shit, the annoying people on here have such a trigger-happy radical position that it's tiresome and it feels like they're about to harass you for being *just one little step below* the "every llm user ever must be burned at the stake and everyone who disagrees with that (even while hating llms) too" stance

Ah yes the USB modes we know and love,

Today in "the cyberpunk future we got": at a little local awards ceremony for partners of a cooperative bank, one neighborhood org was gifted —no joke— some RAM sticks, an SSD, and a bunch of food. Absolutely last place I expected to encounter the DRAM&NAND crisis at but here we go

@firefoxwebdevs@mastodon.social 'The intent to ship on blink-dev states web developers as "Strongly positive"' wow. absolutely comical. People hate Mozilla for being too positive towards LLMs… nothing involving LLMs can have a "strongly positive" reaction. Just how high on their own supply are they at Goog? Did they get an LLM to generate the web developers' reaction?

Woooo hecking yes \o/ the True 100% Zero-Copy Fast Path for Wayland SHM sharing over virtio-gpu works!! This has been kind of an open side-quest for me for like a year. Finally was motivated to actually-just-do-it by the fact that on Xen it's actually easier to use "guest" memory rather than "host" (wellllll, I guess "in a clean upstreamable way" only, actually) and we'll need guest support for that and upstreaming said support will need a KVM-based demo so here it works on libkrun. It does involve one slightly cursed(?) step which is that the Wayland proxy in the guest does just grow the provided pool memfds to align to page size but it seems like clients don't mind. And wow I usually don't really think about just how fragmented memory buffers get, but udmabuf_create_list is currently limited to 1024 entries by default (configurable w/ udmabuf.list_limit=..) and these buffers are frequently spread across many thousands of discontinuous GPA ranges. The ridiculously massive buffer allocated by the foot terminal goes up to 40K ranges! i.e. just the command to make a shareable kernel object out of those guest memory ranges takes up close to a megabyte :D

@soph@grrl.me Ed himself previously said something like "8x-9x" but this sounds more like "40x-150x" which holy shit

wow this blew the f up ummm here's my soundcloud https://social.treehouse.systems/@angelastella/116584572554305300 https://mastodon.la/@beckermatic/116705957916209536

@agowa338@chaos.social right, seems like one usually has to rig up some mosfets to get the legacy 5v behavior when the battery is dead and PD communication otherwise

@mntmn@mastodon.social yeaah microsoft surfaces use uart for this!

@kuchenmampfer@chaos.social the screenshot is from aliexpress yeah you can also just plug a C-to-A cable into an A-receptacle-to-C-plug adapter, or chain the A-receptacle-to-C-plug with the forbidden cursed C-receptacle-to-A-plug one etc.

@agowa338@chaos.social LOL but no, the Switch is mostly fine actually. It actually supports PD, even. This is about the junk that treats USB-C ports as if they were just micro-B. Like my label printer that I thought just broke, until I eventually plugged in a C-to-A cable and it started charging again…

@tante oh wow, the design podcast guy I listened to over a decade ago is even more based now, that's nice to see

@xssfox@cloudisland.nz mmm this begs the question: is anyone working on local free software that completely removes the need for the stupid "cloud"?

@sushee libkrun can be used as a runtime in podman! it's literally the same podman as always but you swap out the isolation backend just like that

@q66 who even says it must be eliminated? outside of reactionary unix conservatives whose opinions should be permanently redirected to /dev/null

@theartlav@anarres.family the wayland socket is provided by casilda which composites onto gtk widgets, and the gtk app is streamed into the browser via broadway

@toldtheworld@mastodon.social sound borger??? (searches) Ohh that thing, I remember that one!!

@agowa338@chaos.social that's a silly issue, but no, if you have a smart device that actually talks PD over CC pins, it's not missing any resistors on those lines.

@mxchara@seattle.pink @stavvers@masto.ai so Rod is like a kinkster of christianity,, well that explains the possession and exorcism fetish,

@noisypegasus@equestria.social @UberZeitgeist@mstdn.social @tante@tldr.nettime.org @danmcquillan@kolektiva.social fuckin' case in point about the destruction of trust due to people just assuming anything to be generated oops

@wezm@mastodon.decentralised.social Fossify is a really good replacement for the stock "basics" like messages, contacts, calendar, gallery. (But also getting away from Android is even better :p)

@mntmn@mastodon.social the nexus7 form factor is baaaack!! it's also basically the form factor where you can't just get an existing device and recycle it with real linux because uhh android vendor didn't make any that i know of in the last few years it seems lol

@s0@cathode.church the path of least resistance

@hailey@hails.org AF_NETLINK, AF_RXRPC and AF_ALG are used in the (combined) exploit, even. uhh podman/pasta needs netlink for itself but it sure shouldn't expose netlink to random programs inside of the container!

@teno@mas.to qué hace el nRF24? 0w0

@cwebber@social.coop heh.. adhd moment I guess: even as a kid back in the day I never got the appeal of MMOs. they always seemed unattractive to me, like a boring chore or something. literally never understood the appeal

@elly wow i haven't heard of Spintrol(l) before

@f4grx @j_r @emenel dhh is rich. like actual big cash money rich. so yeah it just has to be that lol

@pi_crew@social.project-insanity.org oh is that with a USB camera or something? raw v4l2 was supported out of the box with fully stock waydroid i think

@elly oooooh i hadn't thought about this before but do any cool XR specific sensors go through the sensor hub? hm uboot UFS.. on kodiak there's this strange issue where UFS 2.x works but not 3.x in u-boot

@mansalia@social.maid.zone yes, but if it's broadwayd it would be alternating between wayland and web browser for every level of nesting

@mansalia@social.maid.zone yes

@rrustema020 @notjustbikes could this finally convince the super-rich to become anti-SUV? 🤔

@Feral_3D @aparrish @cwebber see also: https://youtube.com/watch?v=E99FnoYqoII

@pi_crew@social.project-insanity.org libcamera backend?

@serriadh@social.treehouse.systems lol wat?? o.0

@cubeos@hachyderm.io @david_chisnall@infosec.exchange @mjg59@nondeterministic.computer only a "hardware IP" with intel, right? on qcom it's an SPU applet. on amd it's also some PSP thing i think?

@lucanalin@mastodon.world yes

@mjg59@nondeterministic.computer @cubeos@hachyderm.io @david_chisnall@infosec.exchange it is always "on a dedicated secure enclave" but definitely not Microsoft hardware in all cases. You can easily confirm that from various vendor docs. On Qualcomm SoCs it's SPU firmware, and in fact the "bios" only loads the lite version which only contains the TPM and none of the chip-to-cloud stuff. Only Windows boots the full version.

@nikitonsky I'm all for dunking on Apple but "loading 40 icons is much harder to do than playing 400 videos" is just one of those things that seem crazy from a "normal person perspective" but make perfect sense from the inside

@mjg59@nondeterministic.computer @cubeos@hachyderm.io @david_chisnall@infosec.exchange oh maybe it was vice versa — AMD included the MS-designed HW but Intel kept it in the ME. I remember that it's only one of them that included MS HW.

@MartinEscardo outside of the slop thing, that's quite the rose-tinted-glasses take

@headius@mastodon.social damn that's scary. I'm quite a hater of the whole LLM thing and the deskilling is certainly one of my concerns but I did not believe that some of it would be so immediate, so fast. WTAF

@rebeccawatson oof I can't even with the website being called "UnHerd", that's just, the irony is too much
