Redis - Pick the Right Data Structure
Brian O’Rourke in a post with tips about Redis:
Here’s our standard reference table for Redis datatypes, their most common uses, and their most common misuses.
Even if most of these are just common sense, it’s good to have some sort of cheat sheet around when modeling your data.

Use your know GIT skillz
A few days ago I had that situation were I’m accidentally commited and pushed changes in the wrong branch. Directly in that moment a few questions run through my head: “How to revert that?”, “Is there an easy way?”, “Are my current GIT skillz enough?” and “Why I’m so stoopid?*”
After fighting with those questions I had an easy solution for my problem:
- In my case, I wanted to keep my changes, so I
git checkout -b my-changesa new branch. git cherry-pick accident-commit-hashthe changes from the branch I accidently commited in.- Than I
git checkout accident-branchagain andgit reset --hard commit-hashthe branch to the commit before. - After fixing my local branch, I also needed to fix the remote branch, so I
git push --force origin accident-branchto solve also that problem.
After those four easy steps everything was fixed & clean again - Hooah! :)

DNS published?
Some domain providers have this annoying default TTL (30 minutes) for DNS zone file changes, so I wrote a simple Ruby script that checks for me every minute if the given domain is now published and reachable. Here is the Gist code of that script:
Be careful, it’s super simple! ;)
