I needed to do an n-ary tree traversal recently with some Javascript code that I’m working on and I initially wrote an iterative n-ary tree-traversal algorithm (using a node stack with a while loop). I wanted to keep track of some extra (depth-dependent) data during the traversal and I didn’t like the way I was…

Downtime and System Upgrade
Sorry for the downtime. My webserver had a failing hard-drive and I figured that while I was replacing the hard-drive, I would upgrade the entire machine as well. The box was a Pentium 4 1.4Ghz with 512MB of RAM that I hadn’t upgraded since I first built it in 2002. Now it’s been upgraded to…
Download ShapeWriter APK
I tried to install ShapeWriter from the Android Marketplace yesterday and couldn’t find it (I was trying to reinstall it after flashing my phone with Cyanogenmod 5.0.8). After searching the interwebs, I found out that it had been removed from the marketplace on June 20th indefinitely (supposedly for QA issues). Luckily I had backed up…
StackOverflow FAIL
I saw this question on StackOverflow today. I thought it was hilarious!
Regula: An annotation-based form-validator written in Javascript
Regula is an annotation-based form-validation framework written in Javascript. There already exist a few frameworks that address form-validation in Javascript, but I have found them to be somewhat lacking. I have thought about writing one of my own for some time, but I honestly had no idea what form it would or should take. I…
Akismet flagging everything as spam
If you’ve been commenting on posts and now seeing anything, it’s because Akismet as been flagging all comments as spam. I don’t know why. I think it started after I upgraded WordPress. I’ve turned it off for now. Oh well.
GitHub broke my scp
I set up git on my FreeBSD box so that I can commit my code to GitHub. Today I tried to scp some stuff over and I was met with this rather unhelpful message: vivin@serenity ~/Projects/code $ scp -r [email protected]:~/code/agnostic . Password: ps: Process environment requires procfs(5) Initializing new SSH agent… vivin@serenity ~/Projects/code $ I…
CherryBlossom
I’ve created a project page for the CherryBlossom programming language. You can check it out here. The interpreter is written in perl.
Introducing CherryBlossom
Over the past month, I’ve been working on a new project. It’s called CherryBlossom, and it’s a way to write programs using haikus. Strictly speaking, CherryBlossom is a brainfuck analog. I actually spent more time writing the obligatory “Hello World” program in CherryBlossom than I did writing the interpreter for the language. The idea behind…
Maven project for Generic (n-ary) Tree in Java
Guus was kind enough to make a maven project for the Generic Tree. He also fixed an error in my equals method for the GenericTreeNode (I intended to do Object.equals(Object obj) but was doing GenericTreeNode.equals(GenericTreeNode obj). Since it’s a maven project, you can easily create a jar out of it and add it as a…
