Software Auralization

Have you heard the latest track by gzip? Maybe it’ll end up on a “Greatest Hits” album alongside Philip Glass.

Visualization techniques such as animated algorithms can help programmers better grasp the abstract theories that make software work. Could auralization, the sound equivalent of visualization, provide similar insights? Postgrad student (and J. S. Bach fan) [Cessu] developed a program to do just that. By carefully mapping registers to notes, and slowing the tempo to a human timescale, the result is a cacophonous machine that offers a glimpse into the operation of various programs. You might find the resulting minimalist “music” insightful, entertaining…or maybe just incredibly grating.

fritzing

Fritzing is an open source project designed to help you move from a prototype to a finished project. Aimed at those basing their projects around Arduino, you start by building your physical prototype, then recreate it with Fritzing software’s graphical editor. From there you can generate a schematic, PCB artwork, and PCB production files.

Bulk Rename Utility

Everybody hates it when they have to rename a fileset to fit a new naming scheme. Instead of doing it the hard way and writing a one-time script to go through and rename everything, check out Bulk Rename Utility from [Jim Willsher]. It provides you with a multitude of methods to take care of business and allows you do pick your favorite method, be it regular expressions, simple finding and replacing, prefix/suffix modification, or a combination of many more.

However, if the sheer amount of options available overwhelms you or if you just want an easier way to do things, check out A.F.5 from [Alex Fauland]. A.F.5 offers features like adding a counter to your filenames, change file attributes, and save your rename settings out to a file for repeat use.

Twittering Keylogger

July 1, 2009 by Zach Banks 16 Comments

[Kyle McDonald] sent in his latest project, a software keylogger that twitters what you type. He wrote it using C++ and OpenFrameworks. It logs each keystroke, then it posts to twitter 140 characters at a time. To protect himself, he set up a whitelist of private strings like passwords and credit card numbers that would be stripped before posting. If the twypewriter followed him, his keystrokes could be recreated.

[thanks Kyle]

Bus Pirate Firmware Update V0g

buspiratefirmwarev0g

Firmware v0g for all Bus Pirate revisions is now available. Updates in this release include a bootloader, frequency generator/pulse-width modulator, SPI bus sniffer, MIDI library, configuration reports, improved user interface, and bug fixes. v0g is also the first firmware to fully support the v2 hardware branch.

We’re really proud of this release as it brings a much more consistent structure to the internal operation of the Bus Pirate. It lays the foundation for future CAN, LIN, and OBDII libraries, and it supports localization and translations. Install and upgrade instructions are included with the firmware. Report bugs on the project issue tracker.

We document the new features after the break.

High School Students Hacking Electronic Tests

August 27, 2008 by Caleb Kraft 30 Comments

[Alex Papadimoulis] wrote about ingenuity and hacking in high school. Immediately after the teacher’s installed a new electronic note taking and test giving software, the students began hacking. They managed to find several ways to ace their tests, none of which involved studying hard the night before. Ultimately, the teachers went back to the old system to prevent such shenanigans.

Neo FreeRunner Software Review

July 10, 2008 by Kimberly Lau 3 Comments

A first look from Ars Technica at the newly released Neo FreeRunner phone by OpenMoko reveals some interesting information. There are three different software stacks available to use; the Neo FreeRunner will ship with the GTK-based stack, referred to as om2007.2. It offers conventional smartphone applications, but most importantly, it includes “full root access to a Busybox shell with all of the standard scripting tools like sed and awk”. The ASU stack is what OpenMoko developers are currently working on; there are promises of a more user-friendly experience. The FSO stack, also currently in development, aims to resolve the issues brought up by having different software stacks for the same phone. Since none of the stacks are considered “fully functional”, OpenMoko may have a difficult time attracting a mainstream audience. Hackers may be hampered by the lack of available documentation, although there are resources for OpenMoko enthusiasts, if you just search hard enough. The final conclusion? While OpenMoko may be difficult to use, it compares favorably to competitors such as Google’s Android platform, which is less flexible.
