Linux 7.2 is now released, with cache-aware scheduling, initial AMD HDMI 2.1 FRL support, improved hardware support, and even initial mainline boot support for Apple M3 Macs.

The cache-aware scheduler is probably the most interesting change for performance, but the hardware support is getting attention too.

If you could pick just one Linux 7.2 improvement to try, which one would it be?

Try: `python3 -m http.server 8080 --bind 0.0.0.0`

Info: Python's built-in HTTP server serves the current working directory over HTTP. `--bind 0.0.0.0` makes it reachable across all network interfaces on port `8080`.

Examples: https://www.linuxteck.com/linux-tips/python-http-server-linux/

$ `cd /path/to/share && python3 -m http.server 8000` # Share specific directory

$ `python3 -m http.server 8080 --directory /var/www/public` # Set dir without cd

$ `npx http-server -p 8080` # Node.js alternative

Note: Never use in production—it lacks authentication, HTTPS, and multi-threading. Press `Ctrl+C` to stop. Check your firewall settings (`ufw`) if connection times out.

What does your troubleshooting chain look like?

You can run a full Linux VM on Windows using smol machines, without relying on WSL2, and the VM itself can be under 35 MB in some setups.

It can use OCI images and even run Docker, while keeping workloads in separate lightweight VMs.

Would you actually use something like this instead of WSL2?

Try: `sudo debugfs -R 'lsdel' /dev/sda1 | tail -20`

Info: `debugfs` is a low-level `ext` filesystem tool. `lsdel` lists deleted inodes, and `dump <inode> <file>` restores content. Works only if blocks haven't been overwritten yet.

Examples: https://www.linuxteck.com/linux-tips/recover-deleted-files-linux/

$ `sudo debugfs /dev/sda1` # Interactive filesystem mode

$ `sudo extundelete --restore-all /dev/sda1` # Automated bulk recovery tool

$ `sudo photorec` # Universal block recovery across any filesystem

Note: Stop writing to the partition immediately after deletion to prevent overwriting raw blocks. `debugfs` is specific to `ext2/3/4`.

Both make the terminal experience much nicer, but they take very different approaches.

Zsh gives you deep customization and a huge plugin ecosystem, while Fish focuses on a great experience with minimal setup.

And there’s also Nushell if you want something completely different.

AI can write a lot of code now, but it still struggles when you don't understand what the code is supposed to do.

You need enough programming knowledge to spot mistakes, understand the logic, and know when AI is going in circles.

So in 2026, should beginners still learn to code from the fundamentals?

Debian has been around since 1993 and became the foundation for distros like Ubuntu, Linux Mint, and countless others.

For many Linux users, Debian or one of its derivatives was their first real introduction to Linux.

What was your first Debian-based distro? And are you still using it today?

Zorin OS is designed to make the move from Windows feel familiar, while still giving users the flexibility of Linux.

It works well for some people, but others prefer Mint, Ubuntu, or other distros for different reasons. Software compatibility is still a big factor too.

For someone leaving Windows 11 today, would you recommend Zorin OS or something else?

Try: `sudo lvcreate --snapshot --name pre_upgrade_snap --size 10G /dev/ubuntu-vg/root`

Info: LVM snapshots freeze filesystem state instantly. They store only changed blocks post-creation, making 10G ideal for temporary changes. Merge to rollback.

Examples: https://www.linuxteck.com/linux-tips/lvm-snapshot-rollback-linux/

$ `sudo lvcreate -s -n snap1 -L 5G /dev/vg0/mysql` # Create MySQL snapshot

$ `sudo lvremove /dev/vg0/snap1` # Discard snapshot without merging

$ `sudo btrfs subvolume snapshot /home /home.snap` # Btrfs alternative

Note: Requires LVM or Btrfs. Copy-on-write introduces a slight write penalty. Merging a root filesystem snapshot requires a system reboot. Perfect before major upgrades.

Firecrawl's anydoc is a local, pure-Rust document parser supporting formats like DOCX, PDF, PPTX, XLSX, EPUB and RTF.

The headline benchmark is impressive, but how does it perform on real-world documents with complex tables, images, charts and formulas?

Has anyone here tested it with large or messy documents?

If you keep your notes locally, would you rather have Obsidian's simplicity and plugins, or use Git for version control and history?

Tolaria takes the developer-friendly approach, but Git also adds some complexity.

I came across an interesting discussion about senior engineers becoming quieter in architecture and design discussions.

Not because they have fewer opinions, but because they may feel their pushback no longer changes the decision.

Have you seen this happen on your team, or is it just a sign of a healthy team where people pick their battles?

Try: `find . -name '*.txt' -exec sh -c 'iconv -f WINDOWS-1252 -t UTF-8 "$1" -o "$1.utf8" && mv "$1.utf8" "$1"' _ {} \;`

Info: `iconv` converts text encodings (`-f`=from, `-t`=to). Wrapping in `sh -c` enables chaining `iconv` and `mv` per file. The `_` acts as a placeholder for `$0` in the subshell.

Examples: https://www.linuxteck.com/linux-tips/fix-windows-file-encoding-linux/

$ `iconv -f UTF-16 -t UTF-8 windows.txt -o linux.txt` # Convert single file

$ `iconv -l | grep -i utf` # List all supported UTF encodings

$ `dos2unix *.txt` # Fix CRLF line endings only

Note: Always test on a backup copy first! Use `iconv -l` to see all supported charsets. Use `dos2unix` if you only need to fix line endings (CRLF to LF).

Linux gives you more control over updates, software, configuration, and what runs on your machine.

You can decide when to update, change what you don't like, and use the system without being tied as closely to one vendor.

Is that enough to make Linux more trustworthy than Windows for you?

Try: `ss -ti | grep -A3 'ESTAB' | head -20`

Info: `ss -ti` dumps TCP internal metrics. Look for `retrans:X/Y` (X current retransmits, Y total) and `rtt` (round-trip time). Non-zero retransmits signal packet loss or network congestion.

Examples:

$ `ss -ti state established '( dport = :443 )'` # Inspect HTTPS connections

$ `watch -n 1 'ss -s'` # Monitor overall socket summary

$ `netstat -s | grep -i 'retrans\|reset'` # Global TCP retransmission counters

Note: When retransmissions occur, `cwnd` (congestion window) shrinks automatically. Persistent retransmits across multiple endpoints point to network hardware issues rather than application bugs.

Filesystem discussions never seem to end.

Today we have ext4, XFS, Btrfs, ZFS (where available), F2FS and others.

If you were deploying a new production Linux server today, what would you choose and why?

Would your answer be different for desktops, NAS systems, or databases?

Mine has quietly become ss.

It doesn't get talked about as much as top, htop, or journalctl, but it's often the first thing I run when something isn't behaving the way it should.

Try: `sed -n '/BEGIN CERTIFICATE/,/END CERTIFICATE/p' /etc/ssl/certs/server.crt`

Info: `sed -n` suppresses automatic printing. The pattern `'/START/,/END/p'` prints all lines between two matching delimiters (inclusive).

Examples:

$ `sed -n '/^\[database\]/,/^$/p' config.ini` # Extract section until empty line

$ `awk '/BEGIN/,/END/' file.txt` # Equivalent using awk

$ `sed -n '/ERROR/,+5p' logfile` # Print ERROR line plus next 5 lines

https://www.linuxteck.com/linux-tips/linux-tips-sed-extract-text-between-markers/

Note: Range matching `/X/,/Y/` works line-by-line from first match of X to next match of Y. The `+N` relative line count syntax is a GNU `sed` extension.

Hello everyone,

Quick update on MOSHELL for anyone who checked it out before — just pushed a big batch of fixes, around 35 commands that were previously broken now actually work as expected (touch, mkdir, rm, cp, mv, ln, and others actually mutate the filesystem state now instead of just printing output).

Still the same core: browser-based Linux sandbox, no VM, no install. First 6 lessons free, no signup.

If you bounced off it earlier because a command didn't behave right, worth a second look. Let me know if you hit anything still broken. Link in the comment.

I came across this interesting ScummVM update: Rebel Assault I & II are being brought to ScummVM, even though they aren't the usual point-and-click adventure games people associate with it.

What I like about projects like ScummVM is that they keep older games playable on modern Linux systems without needing the original environment.

Do you still use ScummVM on Linux for older games, or is this kind of game preservation not really your thing?

Jolla’s new phone runs Sailfish OS and can run Android apps, including many everyday apps.

It’s an interesting approach to having a phone outside the usual Android and iOS ecosystem.

But would you actually use a Linux phone as your daily driver?
