"If this were Rails I'd..."

Mark has finally convinced me to give Ruby and Rails a shot. I'm starting here. Despite failing horribly at my previous goal of learning Haskell, my frustration with Django has reached the point where I am willing to look in other directions.

Python on Android

Note: This post is out of date. If you'd like to run Python on your Android device, please see my Android Scripting Environment project. Here's an early Christmas present for all those Python fanatics (self included) out there! With a lot of help from my friends (thanks Manuel and Thomas !) I managed to install Python 2.4.5 on my G1. It's still rough around the edges, but I think it's a good start. Klaus Reimer has a nice overview of how to cross-compile Python . My instructions borrow a lot from his. Download and build the Android source . These directions assume that you have installed the source to /android_src . Download and build the Python 2.4.5 source . These directions assume that you have installed the source to /python_src . Make copies of python and pgen for use later in the build process then clean up. $ cd /python_src $ cp python hostpython $ cp Parser/pgen Parser/hostpgen $ make distclean Apply the following patch to the Python source. diff -r -c -b P...

Email Injection

Not so long ago, I ran a wiki called SecurePHP. On that wiki, there was one particular article about email injection that received a lot of attention. Naturally, with all the attention came lots of spam. As a result, I disabled editing of the wiki and content stagnated. Still, the email injection article remained popular. About a year later, the server that hosted SecurePHP died and I never had a chance to hook it all back up. I saved the article though and I'm reposting it now. It may be a bit old (I've been away from PHP for a long time), and I didn't write all of it, so feel free to leave comments about needed updates and corrections. Though this article focuses on PHP, it provides a lot of general information regarding email injection attacks. The PHP mail() Function There are a lot of ways to send anonymous emails, some use it to mass mail, some use it to spoof identity, and some (a few) use it to send email anonymously. Usually a web mailform using the mail() funct...

Bot Commander r1 Released

I just published Bot Commander , the code for my Lego NXT rover . There's a lot left to be done, but release early and often, right? Currently it provides a UI for controlling the direction and speed of all three motor ports on the NXT brick. You can link motors together to adjust their speed in unison. In addition, you can enable "Tilt Control" for a steering-wheel-type experience. To use tilt control: Hook up motor A and B to be the left and right wheels of your vehicle. Hold the phone sideways (i.e. landscape). Tilt the phone forward and backward to drive forward and backward. Turn the phone right and left (like a steering wheel) to steer right and left. As you tilt the phone, you'll see the UI update the slider controls for the speed of motors A and B. I plan to expand the UI to provide a lot more than just motor control. Before that, though, I'll push a JAR to make it easy to integrate control of Lego NXT robots into your own Android project. The code...
