In a test #matrix / #element setup via containers when I am trying to make a call via "Element X" app I am getting "MISSING_MATRIX_RTC_FOCUS" error. Any tips? #devops #sysadmin

UPDATE: seems the initial problem was about firewall, now only one user from mobile can start a call, the other users on browser has the button grayed out.

FIXED: final missing part

I'm looking for someone who'd be interested in some part time (6-10 hours a week) of remote sys-admin/devops work.

If you're interested or know someone who is, send them my way.

🧠 Modular Garbage Collectors

For the first time, CRuby can dynamically load alternative GC implementations (including MMTk-based ones) at runtime — opening the door to new performance strategies and future runtime flexibility.

• git bisect (find bug-introducing commit)
• git worktree (work on 2 branches at once)
• git reflog (recover deleted branches)

⚡ From ~30 minutes to ~2 minutes: how a Rails team achieved ultra-fast CI — without rewriting tests.

Parallel RSpec done right, smart workload balancing, PostgreSQL on tmpfs (RAM), and even reconsidering cloud vs physical hardware.

Over a year into seriously job-hunting and it is miserable. I remain stubbornly a generalist #SoftwareEngineer with #Infra background, both close-to-hardware systems and web #DevOps #SRE work. Need US remote or #PDX local, no AI or blockchain.

There doesn't seem to be a consensus on whether #FediHire, #FediHired, or #GetFediHired is the hashtag, so I'll use them all to say: please help me find a job so I can pay the mortgage on my queer misfit den and otherwise provide for myself and my family.

Is the PHP ecosystem just one big xkcd "Dependency" meme?

We rely on legends like @ondrej the "one guy in Nebraska" of PHP. Why no official @php Foundation repo?

It’s the "Glue Problem." Managing PHP's links to shifting system libs across every distro is a massive DevOps task.

The @thephpf stays focused on Core C development; Docker is their "official" path now.

Is relying on community experts a risk or just peak efficiency?

Podman 5.8 just dropped and it's quietly setting the stage for 6.0.

The highlights:
- Quadlet multi-file install (bundle your whole stack in one file, finally)
- Automatic BoltDB -> SQLite migration
- AppArmor support in Quadlet unit files
- podman exec --no-session for faster exec calls

If you're running Quadlet-based deployments, this one's worth your attention.
