Going from a 1G setup with a Peplink and EdgeSwitch to upgrading to 10G uplinks and MultiGigabit Ethernet support, has been about learning. Lots of inspiration found in this sub.

Podman as a Docker alternative on Linux: rootless by default, no daemon, and containers run as systemd services via Quadlets. Covers install, running containers, and where Docker compatibility actually breaks down.

Small office build: UDM Pro, USW Pro Max 16 PoE, dual-WAN failover, and four UPS units on a 20A circuit. The write-up covers the power math if anyone's planning something similar. 11 months later no issues after 18 power outages. The client does not have an automatic backup generator, yet, so outages usually last anywhere from 5 mins to an hour. Replacement batteries cost $50 bucks (search Amazon for B001NJ3H0C). Usually last ~ 3 to 5 years. Cost and maintenance lower than one big UPS failure point.

I made a small browser game. You answer a few questions, then 32 distros (and 16 desktops) fight through a bracket to suggest one that fits how you actually use your computer.

It's meant to be fun, but the scoring and results are real suggestions rather than random. No signup, no ads, only anonymous aggregate stats. There's also a terminal-based campaign mode if you like messing with real commands.

This new and the campaign is only about 40% complete.

TL;DR: GLAD - Gather, Look, Analyze, Document

G – Gather clues and define the problem
L – Look at system status and logs
A – Analyze findings, form a hypothesis
D – Document the fix after verifying

A few things this covers that tripped me up,may be useful:

• The listen ... http2 directive is deprecated as of Nginx 1.25.1
• HTTP/3/QUIC is native in mainline now, no more compiling from source.
• If you're on Let's Encrypt, OCSP stapling is basicallly dead, they shut off their responders in August 2025, so ssl_stapling on; just throws a warning.

Curious what protocol split everyone's seeing and using in production?

tl;dr: Every modern Linux system mounts tmpfs on /run, /dev/shm, and /run/lock by default. Tips on how to add tmpfs instances for builds, browser cache, and script scratch space.

Brian Masinick, shared his history with text editors going back to the early 1980s: TECO, Multics Emacs, writing his own WPS mode on top of EDT emulation at DEC, and landing on Doom and Spacemacs today. With his permission we featured it on the blog. Posting here because the Emacs lineage is the heart of it and this community will get the references better than most.

Explains Linux network bonding, the technique of combining multiple physical network interfaces into a single logical interface to boost bandwidth and provide redundancy.

It matters because bonded interfaces deliver fault tolerance (automatic failover if one cable/card fails) and higher throughput via load balancing, helping Linux users build more reliable, self-hosted networks.

2 years ago, I booked a flight a few months later I had a family emergency so I logged into AA and canceled the flight about 1 week before departure. I spoke to no customer service. I did everything on the website and my FULL miles and fee were refunded.

Today I'm about to book a flight but I notice the cancellation looks different. It says:

>You have 24 hours from the time you first buy your ticket to make changes or cancel for a refund if you booked at least 2 days before departure. 

Is this a change? I've always been able t cancel any time for years now. I didn't realize it was limited now to only within the first 24 hours.

The route is Barbados to Miami.
