Rebase without re-checkout

TL;DR: when using multiple branches, prefer to use “git rebase –onto origin/master origin/master ${branch}” if you want to checkout and then rebase a branch. Let’s say you have the working history: /-*-* A *-*-*-*-*-*-* origin/master \-*-*-* B and you want to push the branch A because your CL has been approved. You have to rebase […]

Git clean. No seriously, clean it.

Working on Chrome, there are lots of dependencies that get pulled, and when I make untracked temporary changes in those dependancies sometimes I just want everything back to normal. So, here’s the scorched earth method: git clean -f -f -x -d This blows away everything git doesn’t know about. Then I do another clean dependency […]

Another weird git problem

Lately whenever I have to rebase I get a weird error about how I have a dirty tree and need to commit files. Falling back to patching base and 3-way merge… error: Your local changes to the following files would be overwritten by merge: <snip> Please, commit your changes or stash them before you can […]

Recent git branches

Sometimes I forget to delete my old git branches, and I forget which is what and who is how. And so on and so forth. So I do this!: git reflog –date=local –all This outputs a nifty list of all the recent commits and which branches they were too. w00t.

iOS timing

git format-patch and git am

Occasionally I need to send a git patch between computers. Yes, I know there are more efficient ways of doing this, but occasionally it needs to happen. So here’s how I do it: git format-patch –binary master.. –stdout > the.patch and how to apply it: git am –signoff < the.patch

Sigh, GoDaddy

Well, it’s official. All my domains are now registered with GoDaddy. Why? Because while they have a website which makes my eyes bleed, they constantly have coupons like OMGWTF FREE DOMAIN TRANSFERS for 5 years. So, I pay nothing. I’ll revisit who to transfer my domains to in about 5 years. Any suggestions until then?

Increase the max number of processes

I ran into this problem earlier today. This will increase the number of processes at a time, above the default 256. w00t. echo ‘limit maxproc 2000 2000’ | sudo tee -a /etc/launchd.conf sudo reboot
