FWIW, plasmashell can recover from dying without nuking the whole session. I think it's kwin that is critical, but I haven't had a kwin_wayland crash in ages. Plasmashell is still wonky in some places, but a crash recovers within a second. Wayland can do some pretty cool things and most people (who work in the space) agree it just has to happen. It's just the nature of how important desktop features come up so late in its adoption that leads to mockery.

When I learned that X11 has been on version 11 since before I was born, very much before I was a wee lad tinkering with Mac OS 7 on a Macintosh TV (it was a Macintosh! With a TV tuner inside it!), I felt that someone forgot to add a 1 to the version number at some point and everyone just collectively said "yeah sure, version 11," all the way until the whole thing almost keeled over at some point in the mid-aughts. Like, they got to 11 in three years and stuck with it? Why are the computer people still flame warring on ICQ so weird about their open source things like that? X11 version 7 point 9. They even got Tim Apple doing it with MacOS 10. A Bad King fucked around with this message at 22:53 on Mar 27, 2023 |

x11r6 is just a fossilized thing for compatibility like user agent strings. You aren't actually using x11r6, you're using a specific version of x.org which has actual version numbers

As a long and flowing gray-beard linux user who deals with embedded Linux: Wayland is fine.

I think wayland is good (although weird in some ways; I feel like too much may have been left to the compositor layer) but I'm still not using it yet because I'm hoping that 100% of the issues will be worked out by the time I switch

i'm on x11 for my day job as well, but it is undeniable that 90% of what x11 does was obsolete and dumb when it was new. some heroic work has been done to drag it along, and i am a *huge* fan of compatibility, keep the thing that works working, but you'd be a fool to have any *love* for x11. wayland is not fully there yet, but it is for sure a *desirable* future once they get it to the point of previously working things working. which seems mostly very close.

X11 stopped being revised when everybody started using MIT-SHM to draw window contents themselves instead of using X11's crappy not-even-PostScript drawing primitives and font rendering commands. Wayland formalizes this status quo and removes the rendering API that nobody was using, but they also added some inter-application isolation as well. Which is all well and good in theory but it has absolutely zero security impact, because to be able to talk to X or Wayland in the first place an attacker has to be running arbitrary code on your machine and by that point you are already 2000 other different kinds of hosed.

I have used Wayland since 2015 and it pretty much just works. Xwayland is pretty good and transparent too. I did lots of X11 programming in my youth and it loving sucked. Burn it all down.

I remember back when X.org was forked from XFree86 and all the drama of Keith Packard being a colossal dumbass by shoving a bunch of code changes right before a release without consulting the entire development team and them revoking his push rights.

Sapozhnik posted:well yeah because you can't just restart the window server and expect all of the protocol state to survive. i think somebody is working on making it work but idk how that would work in the general case. why is it necessary to nuke the window server just to reload the user interface?

Also, unless you're a very special kind of nerd, your X is probably running as root. Is wayland perfect? Nah. Is it marginally better than the alternative? Getting there, for a good number of use-cases.

neither X nor a typical wayland compositor runs as root, it gets fds for the devices it needs delegated to it from logind and everything else can run "unprivileged" and nothing that you care about protecting on a local desktop requires an attacker to get root

yeah both of them specifically don't run as root lol it's actually kind of an interesting experience running a distro in a termux container on android. for the most part root isn't at all necessary (although fakeroot/proot do help) and almost everything you'd expect to work does that doesn't mean it's flawless of course but for a general user it's fine. most people itt would get frustrated by it i think but you can use something like magisk to authenticate anyway

I have a working NCD 17c with the LK201-style keyboard and a correspondingly early NCD-labeled Logitech serial mouse, it’s got the full 8MB of RAM too I need to burn some ROMs so I can boot straight to the X server instead of over the network, but eventually I expect to do that anyway since I want to build new code for it I should also start planning out how to hook up the logic analyzer to capture the interaction with NVRAM to see what else MAME might need to do

alright so basically vulkan has been declared a failure https://www.khronos.org/blog/you-can-use-vulkan-without-pipelines-today the whole point of vulkan was for engines or middleware to compile a complete graphics pipeline ahead of time and allow the gpu driver to do "whole-program optimization" without having to race against vsync. they even had a nice abstraction to deal with the performance peculiarities of tiling gpus. but no, application developers said that was too hard so subpasses are long dead and now we're going back to the directx/opengl model where you swap out bits and pieces of the pipeline pseudo-synchronously and the graphics driver and the application guess around each other where to insert the recompilation stutter. but there's multithreaded command submission now i guess. the whole thing has the stink of political maneuvering by nvidia around it as well. great job

things have essentially come full circle though: gamedevs circa 2013: your api sucks, and you suck, and we hate you vendors: ok, what do you want? gamedevs circa 2013: let us handle shaders and state manually, because you suck vendors: are you really sure? it's not easy... gamedevs circa 2013: yes. you suck and we rule vendors: ok... gamedevs circa 2023: so, uh, we suck at this. handle it for us vendors: WE TOLD YOU

eh, it still appears kinda fully formed with only two of the people being easily established as people credited working in the computer network industry so i'm thinking they probably still looked a fair bit at 4.2bsd - just like everyone else.
