#TechTipThursday: stop stashing every time a hotfix lands.

git worktree add ../hotfix main

Checks out main in its own folder, same repo. Fix the bug there, come back, feature branch untouched.

#TechTipThursday: let git find the commit that broke it.

Something worked three weeks ago and doesn't now, and there are two hundred commits in between. Stop reading diffs:

Git checks out the midpoint […]

Bad rebase, hard reset, deleted branch. Before you panic:

git reflog

It's a log of everywhere HEAD has been, including commits that aren't on any branch anymore. Find the hash from before things went […]

#TechTipThursday: stop losing long jobs to a dropped SSH session.

Before you kick off that big rsync:

tmux new -s migration

It runs on the server, not in your terminal. Ctrl+b then d to detach, close the laptop, walk away. Come back with tmux attach -t […]

Stop drowning in logs:

journalctl -p err -b

Every error from the current boot, nothing else. Add -u nginx -f to follow one service live.

Logs are like receipts. Useless until you desperately need one.

#TechTipThursday: installing NVIDIA drivers on Fedora.

Skip the .run file from NVIDIA's site. Enable RPM Fusion nonfree, then:

sudo dnf install akmod-nvidia

Give it a few minutes to build before you reboot. Secure Boot? You'll need to sign it.
