I don't know the details of what happened between the two projects, but according to Wikipedia [1], libav was abandoned a bit over 5 years ago. Looks like their website (and main git repo) no longer exist. [1] https://en.wik

Happy to see more folks working on fast terminal emulators! Earlier this year, I went through every single terminal emulator in Arch's repos and tested using them while compiling AOSP (Android). AOSP's Soong build system does not

I don't think this is possible, at least not directly. My understanding is that there's a special optimized path for CameraConstrainedHighSpeedCaptureSession recording to MediaCodec surfaces backed by a hardware encoder. If you ca

Kopia is great, though it's worth noting for folks on Linux: non-UTF-8 paths aren't stored correctly [1] and xattrs aren't stored [2]. While most folks probably won't care about the former, the latter can could cause iss

It sucks that these folks are getting laid off. In all my past interactions with them, they've been quick and helpful and never felt like they were just following a script. I submitted this because this might potentially affect users d

The wiki page is just out of date. It's been supported in libarchive for several years, though it's optional at compile time, so this new Windows build might not have it (I didn't check).

I don't mind the look of ligatures too much in most monospace fonts that have them. However, I use my editor and terminal emulator for a lot more than just editing source code in common programming languages. In every single ligature-s

I don't know if it's true for this particular OS, but some OS's bundle the baseband, bootloader, and other vendor-specific images so that they're automatically updated, like with the stock OS.

Do you know if OnePlus uses the same A/B style OTA updates as Pixel devices and whether it supports setting a custom bootloader key? If so, you might be able to use my avbroot project [1]. It roots the boot image, signs it with your ow

Some programs, like sshd and chromium, make use of this fact to change the process name as shown in procfs and ps. On Linux, every string that argv[] and envp[] point to are stored in one contiguous block of memory. Programs can change the

Yeah，AT&T unfortunately tries really hard to make their customers use the provided routers. For customers on the older GPON network (like myself), they provide an ONT and a router. The ONT will not communicate until the router authentic

Interesting! I didn't know coreboot was available for the *20 series. I hadn't touched my W520 since the last warranty replacement. Maybe coreboot will be my next weekend project.
