A spooky Linux networking gotcha 👻
You have a dual-homed server on a public and a private network with IP forwarding off. A service is listening on the IP address of the private interface. Can a client in the public network reach it?

Apple ships one of the fastest, highest-capacity free object stores in the world and nobody is using it. Inspired by @ironseth_s I found a way to get ~12 TB for $0. Paying $0.023/GB for AWS S3 is a skill issue. Use icloud as s3 as the goat of object stores. 284x faster than r2. Seth, let's add this to your stack!
Rocky Linux’s creators just built a Kubernetes engine that lets AI agents manage clusters directly.
CIQ’s new Stratum Kubernetes Engine (SKE) bundles Kubernetes into one signed binary with an MCP server built in.
AI agents can troubleshoot issues and, with operator permission, scale workloads or upgrade clusters.
There are 18 read-only tools by default, with up to 37 available. Operators decide which capabilities to expose.
No separate Kubernetes MCP server to install.
SKE is FREE and open source, in technical preview with general availability expected November 5.

How Docker Run Command Works 🐳
When you "docker run nginx" from the terminal, it feels like launching a regular foreground process - stdin, stdout, and stderr get streamed back and forth, and you can kill it with Ctrl+C. But what happens internally is much more involved 👇

Linux Networking 101: Routing
You're given three separate machines on two different networks. Can you configure basic routing so the leaf nodes can communicate through the router?

pg_dump + pg_restore finished. Exit code 0. Row counts match.
Your database is not ready yet.
One query, 250M rows, Postgres 18.6, cold cache:
→ right after pg_restore: 32.6 s
→ after ANALYZE: 6.1 s
→ after VACUUM ANALYZE: 23 ms 💥
Same data. ~1,400× faster.
A logical dump does not carry the visibility map, and by default not the planner statistics.
25 of 28 migration guides we checked don't say to run VACUUM after the load.
Before traffic:
vacuumdb --analyze --jobs 4
then ANALYZE each partitioned parent
All tests are reproducible, and the scripts are in the post (bonus: podcast episode) 👇

Passenger v0.2.2: .NET 11 and C# 15 support (file-based apps, .slnf, unions, runtime-async stepping), a faster editor, and C#'s language server holding about half the memory. Free and open source, with a debugger, profiler and Hot Reload included. Still free and MIT. #dotnet #aspire

I recently added "dynamic" social preview images for iximiuz Labs, and it was surprisingly fun to build.
TL;DR: headless Chrome-as-a-Service running in a scale-to-zero Fly application screenshots site pages and stores them as optimized PNG images. The best part is that it costs me close to $0/mo and works for any site page that doesn't define its own static override.
