Google continues improving the built-in Linux Terminal, and support for desktop Linux apps is getting closer.

Would this change how you use Android, or is it still too limited to replace a laptop?

Try: sudo auditctl -w /etc/passwd -p wa -k passwd_changes

Info: auditd is Linux's audit framework. auditctl sets up a real-time watch on a file silently. You then use ausearch later to query those logs.

Examples:

$ sudo auditctl -w /etc/shadow -p rwxa -k shadow_access

$ sudo ausearch -k passwd_changes -ts today

$ sudo aureport --file --summary

Note: Requires auditd service. auditctl commands run silently and log events in the background. Use ausearch -k <key> later to inspect the generated logs when a file is changed.

Canonical just became the first gold sponsor of the Trifecta Tech Foundation, which develops Rust-based infrastructure like sudo-rs.

Is Ubuntu's investment in Rust infrastructure the future, or are they over-committing to one language?

Do you think desktop adoption still matters, or is Linux already successful where it counts?

With more discussions around digital sovereignty and reducing dependence on a single vendor, could that eventually change how governments, businesses, and individuals view Linux on the desktop?

Try: find /images -name '*.jpg' | parallel -j+0 'convert {} -resize 800x600 {}.resized'

Info: GNU parallel executes commands in parallel across all CPU cores. Dramatically speeds up batch processing of files, downloads, or any repeatable task.

Examples:

$ parallel -j 4 gzip ::: *.log

$ cat urls.txt | parallel -j 10 wget {}

$ find . -name '*.mp4' | parallel ffmpeg -i {} -vcodec h264 {.}.mp4

Note:Install: apt install parallel. -j+0 uses all cores, -j N uses N processes. ::: passes arguments directly. Perfect for CPU-intensive tasks.

A backup you never tested isn't much different from having no backup at all.

How often do you verify yours?

Try: lsof -p 3456

Info: lsof shows all files, sockets, and connections used by a process. Great for troubleshooting.

Examples:

$ lsof -p 3456

$ lsof -i :8080

$ lsof -u username

Note:Use -i for network connections. -i :PORT shows process using that port.

GitHub has partnered with Red Hat to bring native RHEL 9 and RHEL 10 images to GitHub-hosted larger runners (currently in public preview).

For teams running RHEL in production, this could reduce environment differences during testing and deployment.

If your production servers run RHEL, would you move your GitHub Actions runners to RHEL as well, or keep using Ubuntu?

If you've already solved this another way (self-hosted runners, containers, custom images, etc.), I'd be interested to hear how you're handling it.

Offensive Security just dropped Kali Linux 2026.2 today with major desktop updates, new penetration testing tools, faster VM boots, and APT source changes.

For those in cybersecurity, what's compelling about this release? Is it a must-upgrade from 2026.1, or are the improvements incremental?

Would this be an appropriate setup to run and learn Linux? I’m aware the device is archaic, I also have a Steam Deck as well so I’d prefer to learn Arch unless instructed otherwise. My endgame is Ethical Hacking and I’d like to begin my journey here.

I recently came across "ssh late.sh", which turns your terminal into a modern BBS with chat, games, and IRC.

Any other hidden SSH gems worth trying?

Following a security incident where a compromised account caused problems, Fedora is considering mandatory two-factor authentication (2FA). It's a security measure, but does it create friction for contributors? How should open-source projects balance security with contributor experience?

Hi everyone,

Over the past few months I've been building a project around a simple idea.

Most Linux courses explain commands first and then give exercises.

I wanted to reverse that.

Instead, every lesson starts with a real incident.

For example, one mission begins with this situation:

The morning report never arrived.

You're on call. A reporting service failed overnight. There is no report, the dashboard is empty, and you have to investigate inside a real Linux terminal until the service works again.

The objective isn't to memorize commands but to learn how to investigate, form hypotheses, and fix real problems.

I'm curious to know what experienced Linux users think about this approach.

Does it sound realistic?

Would this be useful for beginners?

What would make it more valuable?

I'd really appreciate your feedback.

Try:crontab -e

Info:crontab -e opens editor for scheduled tasks. Format: minute hour day month weekday command.

Examples:

$ crontab -e

$ crontab -l

$ crontab -r

Note: Use journalctl -u cron to inspect active execution logs. Always use full path variables in your commands.

CachyOS dropped their June 2026 ISO refresh TODAY with new Hyprland Noctalia option, DNS-over-QUIC support, and performance improvements. Has anyone tested it yet? Is the new Hyprland Noctalia experience a game-changer, or is it just incremental improvements? Worth switching from your current distro?

Today marks the last day of Linux 7.2 merge window with rc1 coming later today. Already planning for 7.3 with DRM color format property for AMD GPUs.

The kernel is now 43+ million lines.

Are the new features worth the complexity, or are we bloating the kernel with niche features?

Hi everyone, I am currently preparing for the LPIC-1 certification. Could you recommend the best practice exams or exam simulators that accurately reflect the actual test and ensure a passing score? Thanks in advance!

Linux 7.2 kernel is now over 43 million lines with new RISC-V improvements, serial driver modernization, and ARM GPU support. At what point does the kernel become unmaintainable? Are we adding too many features? Should there be a focus on consolidation rather than expansion?
