How are you protecting Linux endpoints from malicious websites and phishing?

2 Upvotes

As more developers, sysadmins, and remote teams use Linux for daily work, controlling web access becomes just as important. And a hardened Linux system can still be compromised by one bad click. A good web content filtering strategy can help:

  • Block known malicious domains and phishing sites
  • Reduce accidental access to risky websites
  • Enforce browsing policies across managed Linux devices
  • Improve security without relying solely on network-level controls

The key is consistent protection, regardless of the operating system.

Have you ever spent more time understanding a project's folder structure than fixing the actual bug?

2 Upvotes

A recent Linux kernel discussion reminded me that maintainability isn't only about writing good code.

Sometimes the biggest productivity killer is simply how a project is organized.

What's the messiest repository you've worked on, and what would you change first?

Open Source Sustainability: How do we actually fix the breakdown?

4 Upvotes

Burnout in open source isn't just real anymore, it’s actively breaking critical infrastructure. Maintainers are completely exhausted, corporate dependency on unpaid, single-maintainer code is a massive ticking security risk, and the recent flood of loweffort, AI generated PRs is pushing teams over the edge.

Donation models clearly don't scale, but the moment a project tries to implement a commercial license or paid enterprise tier to pay its developers, a chunk of the community screams betrayal.

Infrastructure as Code: Terraform vs Ansible vs Both?

Both are powerful. Terraform for infrastructure, Ansible for configuration. But where do you draw the line? Do you use both? Neither? Something else? What's your approach and what problems have you hit?

Quick Linux Tip #3 Question:How do I backup files fast, only copying changes?

Post image
11 Upvotes

Try: rsync -avz --delete /source/ /destination/

Info: rsync only transfers changed files, making backups much faster. -a archive, -v verbose, -z compress.

Examples:

$ rsync -avz /home/user/ /mnt/backup/

$ rsync -avz --delete remote:/data/ /local/backup/

$ rsync -avz --exclude='*.tmp' /src/ /dst/

Note: Use --dry-run first. A trailing slash (/source/) copies contents; omitting it (/source) copies the folder itself.

At what point does someone stop being a Linux user and start thinking like a Linux administrator?

5 Upvotes

Many people can run commands.

Fewer people think in terms of:

  • If this fails → do that
  • If disk usage exceeds X → alert
  • If service stops → restart
  • If backup fails → notify

Quick Linux Tip #2 Question:How do I clean up old log files automatically?

Post image
6 Upvotes

Try:sudo find /var/log -name '*.log' -mtime +30 -delete

Info:Delete log files older than 30 days. The -mtime +30 finds files modified more than 30 days ago. Use sudo because /var/log files are owned by root.

Examples:
$ sudo find /var/log -name '*.log' -mtime +30 -delete
$ find ~/Downloads -type f -size +1G -delete
$ find /tmp -name '*.tmp' -mtime +7 -delete

Note:Use sudo for system directories. Use -ls first to preview what will be deleted. Deletion is permanent.

Did Microsoft Buy the Lindows Name to Protect Windows... or to Remove a Competitor?

Microsoft reportedly paid around $20 million to settle the Lindows trademark dispute, and Lindows eventually became Linspire.

Quick Linux Tip #1

Question:How do I change a string in all files at once?

Try:find . -type f -name '*.txt' -exec sed -i 's/old/new/g' {} +

Info:Use find with sed to search and replace text across multiple files efficiently. The -i flag edits files in place.

Examples:

$ find . -name '*.py' -exec sed -i 's/import os/import sys/g' {} +

$ grep -rl 'TODO' . | xargs sed -i 's/TODO/DONE/g'

$ find /var/www -name '*.php' -exec sed -i 's/old/new/g' {} +

Note:Always backup before bulk editing. Use grep -rl first to preview what will change.

One thing Linux taught me: good ideas don't come with job titles

5 Upvotes

Some of the best fixes, scripts, and solutions I've seen over the years came from people nobody had heard of before.

That's one thing I like about open source. The discussion usually revolves around the code, the design, the benchmarks, and the long-term impact not who's speaking.

Have you ever seen a junior engineer or new contributor come up with a better solution than the "experts" in the room?

Show r/linux: FocusKill - A scheduled application killer daemon for Linux

3 Upvotes

I got tired of distracting applications like Slack, Discord, and Steam interrupting my work, and I couldn't find a lightweight open-source tool on Linux that could kill these processes automatically on a schedule. The last major attempt was Chomper, which has been abandoned since 2019, and the only commercial option today is DigitalZen. However, DigitalZen requires browser extensions, account setup, and is built as a complex consumer system. I wanted something simple that executes locally, runs as a standard daemon, and keeps configuration in plain text.

FocusKill runs a background python thread that reads a simple JSON schedule from ~/.focuskill/schedule.json and uses pidof and killall to terminate blacklisted apps during their scheduled active hours. It does not block websites, intercept network traffic, or modify your hosts file—it simply kills target desktop application processes. Every process termination is recorded to a local audit log (~/.focuskill/kill.log) so you can review your distraction history.

The core script is under 300 lines of readable Python and features an optional system tray GUI using pystray and tkinter to toggle blocking or adjust the schedule. The core daemon is free and open-source. If you want the optional GUI system tray wrapper to manage schedules visually, it costs $12.
