After probably four hours of effort today, I got another twenty five or so job applications out. Hopefully I'll make it through ATS filters. I'm going to take tomorrow off from the job search if my brain can take it.
I'm still looking for US-based remote contract or full time positions in backend #development or #devops engineering. My resume, etc. is available on my website at https://hobbsc.sdf-us.org
Thanks for all the support so far!
Tired of repetitive IT tasks? This book walks you through real-world PowerShell automation—from parsing data and managing cloud resources to building entire AD forests.
Reliable tools to build more flexible, hands-off systems with code that scales. Great for sysadmins who want to script smarter, not harder.
I just added #AlmaLinux 10 to our Integration Test Target (ITT) lineup: https://github.com/orgs/foundata/repositories?q=oci-*-itt
Looking for #Linux #Containers for your CI/CD pipeline? We’ve built a collection of OCI images:
fully functional systemd (not just a shim!)
unprivileged execution support, perfect for tools like #Podman.
ideal for #Ansible #Molecule testing, see them in action with a collection: https://github.com/foundata/ansible-collection-sshd/tree/main/extensions/molecule

TLS (Transport Layer Security) secures reliable, connection-oriented communications, while DTLS (Datagram TLS) is its counterpart for securing time-sensitive or loss-tolerant traffic over unreliable transport, such as streaming over UDP
Here is a quick comparison of TLS vs. DTLS #infosec #devops

Update to WoodpeckerCI v3.8.0! Now with pipeline author & avatar env vars, BitbucketDC PR file changes support, fixed GitLab MR fetching & improved docs. Smarter CI/CD with every release!

I have a new blog post: Running a Luanti Server
at https://edward.delaporte.us/blog/luanti/server/
Okay, CircleCI is actually pretty dang nice to work with, it's more intuitive than many other CI/CD platforms in its syntax and docs are concise and easy enough to navigate.
Especially like the way they've done the workflows, as it makes orchestration ...easy? Combine that with plugins for major platform deployments suddenly you can do more with one file than some folders of shell scripts and config files
Check out the #VictoriaLogs cluster version!
The latest VictoriaLogs release brings powerful new features and important improvements: Benefits:
Linear scaling
Global queries
Simple migration
The cluster version is specifically designed for scenarios where horizontal scaling across multiple machines is necessary because you're hitting those single-host limits.

TL;DR: podman-compose network prefixing is broken AF. Use manual commands or suffer.
The Great Podman-Compose Network Clusterfuck of 2025
The Problem
podman-compose adds your directory name as a prefix to EVERYTHING.
Working in /usr/srv? Enjoy your srv_ prefixed hell.
The Cascade of Chaos
Started innocent enough → Just wanted Grafana + Prometheus monitoring
Directory: /usr/srv = automatic srv_ prefix on all resources
Tried -p mon flag → Now everything gets mon_ prefix instead
Compose external networks → Looks for EXACT names, ignores prefixes
Result: Container network soup
Network Name Explosion
proxy-tier (the one we wanted)
srv_proxy-tier (directory prefix)
mon_proxy-tier (project flag prefix)
srv_srv_proxy-tier (double prefix bug!)
The Special node_exporter Hell
network_mode: host = can't use custom networks
podman-compose = "LOL let me add networks anyway"
Result = fails to start every goddamn time
The OpenResty Trolling
NPM on mon_proxy-tier
Grafana on proxy-tier
Different networks = NPM serves fallback page
Hours of podman network connect voodoo
What Actually Works
Manual podman run commands with explicit networks. No compose, no prefixes, no bullshit.
#Vibecoding downside = 4 hours lost
Vibecoding upside = could not do any of that shit by myself
