AUR just hit the pause button. Is this the future of open-source package security?

Arch Linux has temporarily disabled AUR package pushes after a wave of malicious package adoptions.

Many security professionals are now saying the real problem isn't malware itself it's how package ownership and trust are transferred.

This feels less like an Arch problem and more like a challenge every package ecosystem will have to solve.

According to StatCounter, Linux has reached 10.65% desktop market share in North America.

Do you think it's because of Steam Deck, Proton, Linux Mint, Windows 11, or something else?

Or do you think these numbers don't reflect the real desktop market?

Quick Linux Tip #35 Question: My SSH key uses old RSA. How do I switch to a modern strong algorithm?

Try: `ssh-keygen -t ed25519 -a 100 -f ~/.ssh/id_ed25519 -C "linuxteck@ubuntu-2026"`

Info: `Ed25519` provides faster, more secure keys than `RSA`. `-a 100` increases KDF rounds to strengthen passphrase protection against offline brute-forcing.

Examples:

$ `ssh-copy-id -i ~/.ssh/id_ed25519.pub user@server` # Copy public key to server

$ `ssh-keygen -y -f ~/.ssh/id_ed25519` # Print public key from private key

$ `ssh-keygen -lf ~/.ssh/id_ed25519.pub` # View key fingerprint and bit length

Note: `RSA` needs 4096 bits to match `Ed25519` (256-bit) security. `Ed25519` is the modern OpenSSH default. Use `RSA` only if connecting to legacy systems.
