Got qemu user mode i386 emulation working today on the powerbook.

It's extremely slow, of course, but good enough for a few small things.

It's pretty goddamn irritating when people write programs that only do 2D rendering that don't support anything but Vulkan/Metal.

I'm looking at you, Ruffle (That flash player clone thing in Rust).

Absolutely no reason to not do an OpenGL renderer except for if you would rather antagonize users and potential developers than have to write a 2D rendering program in OpenGL.

They could have also opted for Agg or Cairo, like Gnash did.

Yes, I am aware of the MESA software rasterizer for Vulkan ('lavapipe' or whatever). It's still a lot slower than hardware accelerated OpenGL, and it also still requires DRI3, which is still broken on some systems.

Golang added system calls for PPC32 now, so it's finally in much nicer shape. Meanwhile, rustc tries to run an illegal instruction and crashes.

yeah, alacritty as well(which just renders text). its especially annoying when you're enjoying the wonders of nvidia under linux, which driver updates always kill the gl/vulkan stack from working till a reboot.
meaning if you happen to pull in updates for those the terminal no longer works.

was never quite convinced on the need, majority of the time you only see the 'performance' in benchmarks, anthing flash still runs horrid in ruffle compared to the adobe standalone player as well.

surprising amount of cases the '''safe''' language of rust kills itself by doing unsafe shenanigans

That's why I don't do nvidia driver updates via apt ;)
I use the standalone installer and grab updates via lynx if necessary after a kernel update trashes everything.I still hate nvidia and want to be gone from them, but the graphics card market is giving me strong signs that I should just wait for the bubble to burst first and then buy a used Radeon.

Need for vulkan? Yeah, in _proper_ benchmarks (i.e., real world performance of software under Vulkan vs. OpenGL, like the dolphin emulator) I actually see OpenGL still coming out ahead.
As for the real adobe player, it's not an option on PowerPC Linux, which is why I wanted to get Ruffle working.
Gnash still can be coerced into building with a few patches, but Ruffle looks pretty solid for AVM1/AVM2 stuff as well, and Lightspark just feels fundamentally brain-damaged whenever I try to use it. I've yet to see it run a flash file entirely correctly. even "All Your Base" has minor issues. Really wish they'd just used Gnash's renderer and bolted on an AVM3 backend, since from what I can tell through my research the renderer is not at all different for AVM3 flash files.

Had to fight with rust to cross compile firefox (actually, seamonkey) for 32-bit Linux today. Rustc 1.52 was trying to be "safe" and guarantee stability or whatever by refusing to cooperate with Mozilla's own build system. Ironic.

I electrocuted my PC twice as I was tinkering with it. The last time I will wear a sweater while working on it.

Crashed the file explorer again.
Come on those were just speedruns, not huge GB videos, why is the damn program/OS so sensitive to downloads? (IMG:[invalid] style_emoticons/default/dry.gif)

results: whe are mother fockers

And I was going to post the clip from Predator 2. "MOTHERFUCKERRR!"

Youtube has rolled out new age gating. That clip is flagged. It can no longer be embedded, and you are supposed to make a Google account, sign in, and send them a credit card number in order to be verified to view it.

Broke my powerbook's charger. Ugh.

Technically it was already partially broken and had been ever since I got it (I had to fight with it to get it to charge things and plug it in just right due to a problem in the connector on the charger side), but it finally decided to break for real.

So I'm gonna be waiting a few days for another one before I use it again. Thankfully, even 65W OEM ones aren't that pricey (they made 45W and 65W ones; my old one was 65W).

In the meantime I'll be messing around with my 32-bit intel laptop (Pentium M) some more. Upgraded from Debian Wheezy to sid successfully and now just tweaking it so my desktop environment feels right (FVWM3).

Have had to recompile quite a few things, since most of my other machines are amd64 and I tend to just do a build once and share between them, but this one's IA32.

I just noticed EH has cloudflare protection now...not sure how i feel about it.

I wish the TV guide of my Internet box was made with proper friendly coding, but from the page inspector, it's just a horrible mess, lots of invisible elements, real stuff is hidden behind empty containers, things you find through a search are not in any sane order when comparing them visually.........absolutely no hope to filter/improve it through a script or anything (IMG:[invalid] style_emoticons/default/sad.gif)

edit: no idea about technical details, though from NoScript, I can at least tell it should not use anything hosted from another domain or stuff like that, it should all be self-contained somewhat.

Wait, is your internet box tv guide using HTML? And webkit or something?

as long as it doesnt go down on the yearly cloudflare fuckup or starts banning my ips

completely unrelated, decided to get another analog scope after years of not having one. crt got smashed in a move and it wasnt worth the price to fix at the time.
theres some good market going on where people just want to get rid of their 'ewaste' for cheap, managed to pick one of these up(still yet to be shipped but deal through) for near nothing:

will finally make all the nicely provided wave forms useful again in the service manuals of my other junk

Looks good. Way nicer than my only scope.

looks plenty nice though.
dont think I've ever seen lectrotechs pop up around here, neither does it yield a whole lot of documenation online.
whats the bandwidth on that and what do you use it for?

I don't have documentation either, so I have no idea what the bandwidth is. Don't even know what the probe impedance should be.

But I use it for analogue television signal stuff and it's fine for that.

for what its worth the to-50, which does have a findable manual, is the standard but respectable 10MHz bandwidth and 1MΩ input impedance so its probably at least that. neat little scope regardless.
forgot already how nice the old analog scopes are to have and work with, glad they're still kicking around

did you ever have to do any recapping or other partswaps on yours or is it still original?

I really, really need to recap it.

When I first got it it would smoke after a few seconds (while still showing a trace), so I did open it and replace THAT cap years ago. I did the canister capacitor as well at that point. Just replaced it with two or three individual caps; didn't try to stuff it or anything.

The rest of the caps are all original.

This scope has some discrete transistors on a single-sided PCB inside; the only tube in it is the CRT itself, so that's actually pretty good from a maintenance perspective. It's some old hitachi static deflection tube I can't find a datasheet for.

All in all, it's not too shabby, and I think it might also be capable of acting as a vectorscope but I haven't tried to do it yet (see the banana plug labels on front).

I think I'll clean the front panel again, too, if I do that.

The trace is a little wobbly, so I think recapping it properly would be really good for it. Sometimes I have trouble getting it triggering properly, too, so I hope that doing that and maybe cleaning the potentiometers and switches will help with that.

I used it to demonstrate to a friend who doesn't mess with electronic hardware much (just a programmer) how 480p and 480i differ in horizontal frequency the other week. Bascally had been trying to do it verbally, but once I showed on the scope how 480p would draw _two_ scan lines in the time it took 480i to draw one, I think it clicked for him. Also showed the difference between 480i and "240p." So I think now he knows what a 960i signal would look like.

Thought:
It's fucking stupid how systemd doesn't read /etc/modules for parameters.

Found a rule I can put in userChrome.css that will change Seamonkey's UI font.
Might also work in Firefox.

CODE

window, page, dialog, wizard, prefwindow {
  font: 9pt "Comic Sans MS",Tahoma,"Liberation Sans",Arial,Helvetica,sans-serif !important;
}

Reminds me of a time before I had learned to hate Comic Sans

seems to be the state most of these analog scopes are in these days

all very neat, be sure to post here if you end up ever going into the repairs.

thought of the day: found out my power supply shorts ground with the positive voltage rail, no clue why and it causes a heap of headaches.
opened it up and couldnt find any clear short or issue, not the plugs either.
ended up just adding a bodge switch to toggle ground when in use:
