Making The diNovo Edge Work On Ubuntu Lucid

The Logitech diNovo Edge is a pretty slick Bluetooth keyboard. It's thin, light, has months of battery life, and looks great too. It even works out of the box on Ubuntu Lucid. Well, almost.

I had trouble with it disconnecting. It would be fine for a day or so, but then not work some evening. Sometimes just the keyboard would stop and the touchpad would be fine. Other times it wouldn't work at all.

I had read that one of the great things about the keyboard is that it's capable of pairing with the dongle without any help from the OS. However, this only works if the dongle isn't initialized as a Bluetooth device. For example, in the BIOS screen, the keyboard works flawlessly. So, I set about preventing it from being initialized as a Bluetooth device.

There's a lot of bug reports and workarounds related to pairing problems, etc. and I didn't have success with any of the suggestions. Instead, I did something similar to this more recent suggestion and changed my udev rules. However, instead of making the suggested alteration to the Logitech device rule, I simply commented out the rule entirely. These are the lines of interest in /lib/udev/rules.d/70-hid2hci.rules:
# Logitech devices
KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \
  RUN+="hid2hci --method=logitech-hid --devpath=%p"
Now that my dongle is not initialized with hid2hci, I can bypass doing any Bluetooth configuration in Ubuntu whatsoever. Flawless victory.

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Note: This post is out of date.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...

Review of Fable III

Damon says : Fable III is the most disappointing sequel since The Kingdom of the Crystal Skull . Laura says : I was disappointed. The worst part was that the game was okay - maybe a 6/10 or 7/10 thanks to the Darkness Incarnate quest. It wasn't great, but it wasn't so poor that I felt I could legitimately hate it. The graphics are fun if cartoony, the sound is good, the gameplay is easy , the customization is almost non-existent, and the story is mediocre at best and boring at worst. Oh, and for some of the achievements you need an Xbox Live account, which annoys me to no end. The environment in Fable III is as rich as ever. Plenty of different regions, all with different climates, peopled by various citizens/denizens/enemies that change as you play. As always, the people of Albion are incredibly chatty, but since Lionhead seems to have supplemented the new stuff they recorded with all the random NPC comments from Fable II, there is enough variation to not driv...
