Linux - Authenticate with Android Phone or TOTP?

Hello. I recently acquired a Surface Go (1st gen, 4 GB RAM, 64 GB EMMC) and installed Fedora Workstation (and Phosh as a second DE). I do not have a keyboard for this device, so usually, I have to use the on-screen keyboard. Entering a sufficiently secure password whenever I wake it from sleep or need elevated permissions/sudo...

How Wayland handles security considerations vs MacOS Quartz or Windows DWM?

As I understand it, X11 has many inherent security concerns, including programs being able to read the contents of other windows and intercept keystrokes.

Discussion of CVE-2017-5226

Extracting frames from a video with ffmpeg very slow if not using jpeg

I’m trying to extract the frames of a video as individual images but it’s really slow, except when I’m using jpeg. The obvious issue with jpegs is the data loss from the compression, I want the images to be lossless. Extracting them as jpegs manages about 50-70 fps but as pngs it’s only 4 fps and it seems to continue...

[SOLVED] Using clangd with vscode to develop a flatpak

I’m developing a program in C++ targeting flatpak, since I’m on an immutable system I’d rather develop for flatpak than try using a container (plus I can’t get SDL to open a window in a container anyway). Everything works with GNOME Builder but it’s not as nice to use as vscode: less syntax highlighting, doesn’t...

Is there a better way to browse man pages?

For many, many years now when I want to browse a man page about something I’ll type man X into my terminal, substituting X for whatever it is I wish to learn about. Depending on the manual, it’s short and therefore easy to find what I want, or I am deep in the woods because I’m trying to find a specific flag that appears...

Distro for n100

I’m trying to decide on a distro for my n100 mini pc. It’ll be for watching content, browsing the web, using discord And playing music. I have Garuda running in it right now just as a tester to see how it did at emulation and honestly it ran 3DS games pretty swell lol. But it feels very bogged down overall. Anything really...
