Can you make good use of an original Commodore PET computer? This one is yours for free if you can pick it up in Los Angeles (near USC). My parents bought it in 1978. It has the famous chiclet keyboard and integral cassette tape drive. It doesn't work at this point, which someone told me is probably due to some bad RAM chips but I don't actually know. The screen shows random squares when it's on.

Boosts for reach appreciated.

After around 23 years, I think I finally made a decision to switch from #Linux to #OpenBSD. It gives me this fantastic feeling of discovering new horizons and seems much more coherent. Also has no #techbros behind it.
I might even remove Linux from main SSD and leave it only on my USB disk to play one old Windows game that I have.
It seems like the only thing I will miss is battery life on Linux. But I'm ready for this tradeoff.

@claudiom From my experience putting A/UX on my IIfx, the install itself doesn't take too long, it's everything else you need to do afterwards: the configuration, getting a local copy of jagubox set up, running updates..

There's a repo here with a script (systemupdate.sh) that will run the recommended updates for you once you've got a local mirror of jagubox: https://github.com/smallsco/Apple_AUX_3.1.1_Setup/blob/fix_typos/SystemUpdater/systemupdate.sh

(make sure you use the `fix_typos` branch from my fork - the original hasn't merged my changes yet and it will breaks due to some typos)

Apple_AUX_3.1.1_Setup/SystemUpdater/systemupdate.sh at fix_typos · smallsco/Apple_AUX_3.1.1_Setup

Built three network analysis tools over the past year. FOSS.

netgrep. Rust packet analyzer. TLS decryption, stream reassembly, interactive TUI.
termshark. Go. Forked the terminal Wireshark UI, refactored, added a web interface.
wiregraph. Real-time network traffic visualizer. Rust backend reuses netgrep's parser. Embedded web dashboard with connection matrix, protocol breakdown, activity.

I still can't even that my now nearly 80 year old mom has been on Fedora on a thinkpad e520 (2011) for a decade and it all just works.

I checked her laptop just now and it's fully up to date on fedora 43, so she's done like 20 version upgrades autonomously too. The battery has degraded a little but the whole thing still works fine and she's very happy with it.

This is how things should be, this is peak computing tbh.

You just provisioned a fresh Linux server. Within minutes, the SSH brute-force bots will arrive.

There are too many ways to build a firewall in Linux. I wrote a practical guide to the four major tools: iptables, nftables, firewalld, and ufw, including their mental models and deployable configs.

Also includes a deep dive into the "Docker Trap" (why Docker silently bypasses your default-deny rules) and how to fix it.

(And yes, I still spend the intro and conclusion reminding everyone that FreeBSD's PF is the undisputed king of packet filtering. Let's argue in the replies.)
