xz-utils backdoor situation (CVE-2024-3094)

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

Recording 4k 4:2:2 from Brio 4k In Linux using FFMpeg

Turn auto-exposure off, set absolute exposure to a low level and use gain to compensate for low light if needed. E.g.:

v4l2-ctl -d /dev/video2 -c exposure_absolute=400
v4l2-ctl -d /dev/video2 -c gain=110

# check with
v4l2-ctl -d /dev/video2 -L

secure communication

Why?

Since it is not possible to rely on the encryption that is provided for us in our daily applications (email, chat, etc), so, I decide to create this method as an alternative to quickly send sensitive data through current chat applications, email, etc.

How?

Using openssl in both sides (the sender and the receiver) is possible to exchange encrypted messages using our preffered chat application. In this process, I tied receiver's github account with his SSH public key, that way we can believe a little bit more if the receiver is who we think he is.
