Using padding in encryption: "The most common query we get about cryptography concerns padding with a block cipher.
If you have to encrypt some data to send to another user and everything else works OK except the last few bytes, your problem is probably one of padding. Read on.
This article describes the mechanics of padding with examples using common block encryption algorithms like DES, Triple DES, Blowfish and AES. It considers where you should use padding and where you don't need to."

How to build an evil automated zombie blog for advertising revenue
How to build an evil automated zombie blog for advertising revenue: "What’s an Evil Automated Zombie Blog? Glad you asked! It’s when you leverage RSS feeds to automatically create blog posts from other blogs and news sources. These sites are good for generating traffic from Google, and can run without you every having to create a single real blog post. After a short period of time, your blog will amass a large number of posts around a given topic; the very thing Google bots like to gobble up.
WARNING: These types of mindless zombie websites are considered evil in the blogging community – lets do it anyway!
The technique we’re about to cover caused one hell of an uproar while writing my WordPress Top Plugins book; the editors and proofreaders expressed their hatred for the very plugin we’re going to be using to setup an auto blog – WP-O-Matic. They said things like “Auto blogs are evil, and this plugin should not be included in the book” or “This plugin will make it to easy for people to steal other peoples content”. Never the less, I fought and won. WP-O-Matic is a great plugin with a lot of practical applications; what we’re about to cover is NOT one of them.
Please understand that what we’re about to build will be looked down upon by purist, but hell that’s what makes it fun!"

android-rss - Android RSS Feed Reader - Google Project Hosting: "Fully functional Android RSS reader created as a way to learn the new Android platform SDK. This project is an ongoing effort to better understand and embrace the Android design philosophy, welcoming comments and additional contributors.
Project Status
This project is just before release 0.1. It is a functional news reader, but does not contain all the features you might expect from a full-featured distributable application.
The target audience is primarily developers interested in further exploration of the Android SDK. Source code is available, and can be accessed through the Subversion repository hosted here."

Performance Tuning Garbage Collection in Java
Performance Tuning Garbage Collection in Java: "2.1 Performance Considerations
Ways to measure GC Performance
Throughput - % of time not spent in GC over a long period of time.
Pauses - app unresponsive because of GC
Footprint - overall memory a process takes to execute
Promptness - time between object death, and time when memory becomes available
There is no one right way to size generations, make the call based on your applications usage."

Ad Hoc Data Analysis From The Unix Command Line - Wikibooks, open books for an open world
Ad Hoc Data Analysis From The Unix Command Line - Wikibooks, open books for an open world: "Once upon a time, I was working with a colleague who needed to do some quick data analysis to get a handle on the scope of a problem. He was considering importing the data into a database or writing a program to parse and summarize that data. Either of these options would have taken hours at least, and possibly days. I wrote this on his whiteboard:
Your friends: cat, find, grep, wc, cut, sort, uniq
These simple commands can be combined to quickly answer the kinds of questions for which most people would turn to a database, if only the data were already in a database. You can quickly (often in seconds) form and test hypotheses about virtually any record oriented data source."
