git svn terrible trouble

I use git svn. I recently somehow (I do not recall) put git svn into a strange state. The symptom was that from master, git svn info would show a branch to which I once committed instead of trunk. I could not figure this out. My solution was to rm -rf .git/svn/ ; git svn […] Read More »

xpath from command line

I’m curious how often someone has written the equivalent of this. I wonder why there isn’t just some tool, and yes, I’ve used xmllint shell to do the same thing. 1 using System; 2 using System.Xml; 3 4 public class Program { 5 public static int Main(string[] args) { 6 var doc = new XmlDocument(); […] Read More »

When Reversing the Interview Process becomes How Would You Do Fun Things in C

My boss’s boss’s pals wrote this: http://blog.exodusintel.com/2012/09/18/reversing-the-interview-process/ Its a story about how someone was asked a crazy fun C question in an interview and how the new team decided to try it. After reading this and discussing it with coworkers, I decided to try it and of course the first thing that came to my […] Read More »

Installing iWork09 from CD without a Mac

You’d think you could just use Apple’s nice CD Sharing program, aka Remote Disc http://support.apple.com/kb/HT1777?viewlocale=en_US But sadly, the iWork09 CD is not an iso9660 disc. Instead it has an Apple style partition table, which was not readable by fdisk and crashed parted in linux, with an HFS+ filesystem. When you insert the disc into a […] Read More »

Setting up a new mac…

3 months ago I started using OSX full time. Today I found myself setting up a new mac. I wished that I had a checklist of my personal must haves. This is that list. XCode (from AppStore) Firefox Aurora Chrome dev channel EnvyCodeR font iTerm2 (and configure with EnvyCodeR font) twitter (only in AppStore) brew […] Read More »

Storyboard Custom Segue For Custom PushViewController Animation

While there are a lot of google hits when searching for custom pushViewController Animation, I found nothing regarding use of a Custom Segue to make it reusable and I also found a lot of misinformation like “it can’t be done with the default UINavigationController.” It can. From your Button, View, Gesture Recognizer or whatever, instead […] Read More »

Scala 2.9.1 on Fedora 16

yum install scala on Fedora will grab all the dependencies, including a JVM, but its a pretty old scala. Luckily it is pretty easy to install scala-2.9.1 by snagging it from rawhide, but just the RPMS only get you so far. Fedora seems to be changing their JAVA_HOME in 17. A little hack, and you […] Read More »

Ubuntu testdrive networked to your LAN

testdrive uses the -net user feature of kvm by default, which is really cool because it becomes a lan client and magically gets internet via proxy. If you want to test server software, you probably want your testdrive VM directly on the same LAN as your host OS. In my case I already had a […] Read More »

Ubuntu testdrive as a base for a Fedora test

Ubuntu testdrive is AWESOME. In my words, testdrive lets you test the next version of ubuntu in a VM with a single command. testdrive ultimately just creates a disk image and runs a virtual machine for you, lets you step through the install from the nightly CD, and then lets you continue to run that […] Read More »

CodeMash 2012 Changed Me

Every CodeMash has changed me. This CodeMash was no different. I’ve attended every codemash. Each is unique and special. I have memories from each that I can point to and say “This is when I realized…” and it is something significant that changed who I am or what I am doing or how I approach [...] Read More »
