im literally losing my mind here strange one, a developer gets locked out right after a password change, even on days theyre not working: The lockout policy is standard, nohting unusual. It feels like an automated attack, or a forgotten device. How can i…
guys pls help i wrote a simple unit file for our app. Running teh command manually works perefctly. Running it as worker.service: systemctl status shows sattus=1/FAILURE and thats it... no useful message... ive relaoded the dameon a dozen times. Ive compared…

not gonna lie this is driving me nuts api.service was fine until todays server patching. now it wont start: The status line says status=200/CHDIR. i didnt touch the unit file. Did the update change smth underneath? the update touhced a bunch of packages, so…

This worked fine last week. Today, on a fresh Ubuntu box, the reverse proxy dies right away: i didn't change the compose file. Port 3000. i've checked Task Manager and htop and i can't find anythnig obvious. Is Docker keeping a ghost reservation?? ive…
We run Terraform from two separate pipelines that share teh same GCS bucket state for the shared dev environment. Since this week, one of them randomly fails with: Retrying usually works. Is this just a race, and how do people normally avoid it? Our setup…
so annoyed rn our pathcing is whenever someone rmeembers and entirely manual, which means some servers get skipped for months. i want to fix this without breaking things... how do u structure rings, approvals and reboots? theres also the reboot question xD…

im literally losing my mind here curious how others decided which workloads to move first. several branch offices, planning a migration. Compliance and Windows Update policies look easy 🔥 Apps and OS deployment look scary. Im especially nervous about app…
