Both long-form posts (articles) and short-form posts (notes) in one feed.

Current Windows 10 has a feature called “Windows Sandbox” which spawns a tiny Hyper-V VM with allegedly a very smart slim disk image thing that shares the OS files with the host, and smart memory management, and so on.. and virtualized GPU support, like virgl in the free world.

So can it run Crysis, or at least Quake? Is it what we need for isolating old games? Well.. it has the ability to load up the host GPU with work and to show the results, but it’s absolutely unsuitable for gaming in its current state. Seems like it uses regular RDP for the window, and there aren’t any special optimizations that make 3D fast. The frame pacing is awful, framerate is weirdly limited, etc.

Also, this is not obviously found on google right now: if you have a compressed disk, you need to decompress C:\ProgramData\Microsoft\Windows\Containers for it to work.

Was wondering for a month why Firefox on my laptop would forget my GitHub session (and some other sessions) after restarting. Turns out “Delete cookies and site data when Firefox is closed” got enabled somehow. Facepalm.

“Why do programs I compile become all-zero files after rebooting?”

well, maybe that untested filesystem-related kernel patch you applied has something to do with it :D

But seriously, if anyone wants to make a very cursed unix system: apply this diff (note: old version by now) to FreeBSD from around now (say the beginning of 2020 — happy new year!), build programs using clang/lld 9.x and reboot.

AWS CloudFormation looks rather disappointing:

  • the import functionality is a joke?? you have to make the template yourself, for some reason there’s no “make template from this real thing” button??
  • even that import thing cannot import an ACM certificate at all, literally says that’s unsupported.
  • the GUI designer thing does not know anything about CloudFront!

What.

I was wondering why I can’t watch Twitch streams in Firefox… turns out they serve a broken player if your User-Agent does not contain Linux/Windows/macOS. Fail.

It’s nice that Microsoft is pushing for all pen tablet (stylus) support in laptops to use the obvious generic set of HID reports. Quite probably, Microsoft is to thank for the Wacom touchscreen in my Pixelbook implementing that. I’ve seen the heaps of code in the Linux kernel to support Wacom’s custom protocols, that would’ve been very NOT fun to implement :)

Took like an hour max to get to working reports in console (dmesg), all that’s left is to evdev-ify it. Coming to iichid pull requests soon (but for now there’s no multiple device support in hidbus, so won’t be mergeable yet).

FreeBSD and custom firmware on the Google Pixelbook

A search for a new thin-and-light laptop, a journey through the Chromebook firmware trust architecture, some FreeBSD kernel development, and finally, something about actually customizing open source firmware.

Noticed something on dmesgd… looks like MIPS (64) isn’t that dead: new(ish) Ubiquiti EdgeRouters have newer Octeon processors — quad-core 1GHz (and with an FPU). And 1GB RAM. That’s much better than the Lite’s dual-core 500MHz && 512MB RAM.

…wait, actually, there’s even big 16-cores (and 16GB RAM) in 10G routers!

“header” is a rather unfortunate word overloading in English. Searching for “tpm header” gives you everything about… well, the physical header on mainboards :D Even with “tpm protocol header”, only Google finds something related to protocol specs, and in the lower half of the first page.

I’ve been rewriting the engine that runs this website in the past few months..

and now, finally, unrelenting.technology runs on sweetroll2! Longer writeup coming, this is more of a test post.

haha wow my SoundFixer addon is on the addons.mozilla.org front page

LLVM 8.0 release highlight (ha): LLDB now has syntax highlighting!

Wow! I’ve been thinking about how a WebAssembly runtime in CloudABI would be an awesome “write once, run everywhere” thing… turns out the Cranelift developers are already looking into CloudABI! Awesome!

Cool ARM laptop news that I missed somehow:

The best Cloud-to-Butt replacement I’ve seen yet, thanks to this page:

Butthole was released in 2016 for Firefox to make Buttflare captchas less painful
