Motorcycle Engine Powered Cars


Autoblog recently posted about the LusoMotors LM23, a track car powered by a Honda CBR1000 that weighs less than 900 pounds. We knew there have been quite a few other home built cars that have foregone traditional engines for motorcycle power plants, so we asked Google for a few project suggestions. It turned up this excellent round up of motorcycle powered cars by The Kneeslider. The usual Caterham suspects show up, but there are many other unique vehicles: from Mini and Fiat conversions to the unique sidemounted engine in the DP1 pictured above. Definitely check out this excellent collection.

Data Manipulation With Sprog


Linux Journal’s [Mike Diehl] pointed out an interesting tool for manipulating data: Sprog. Sprog lets you assemble machines to complete specific data processing tasks. You snap together gears that read input data, process the data in different ways, and then output the results. The input could be a file, URL, database query results, or even MIDI notes. For processing you could be matching patterns, selecting csv columns, converting to uppercase, or executing arbitrary Perl code amongst many other options. Finally the output could be shown in a text window, inserted into a database, written to a file, or sent to your spreadsheet application. Sprog’s site has a section for user uploaded gears and a recipe section for examples like this crossword puzzle solver. Everything Sprog does could be done with scripting, but this is a simple graphical tool that could help you solve a problem without having to know the gory machinery behind it.

ARDAgent.app Still Vulnerable


When Apple pushed their most recent security update, the first thing we checked was whether the ARDAgent issue was fixed. It’s not. This vulnerability lets anyone execute code as a privileged user and versions of this attack have already been found in the wild. While several Ruby, SMB, and WebKit issues were addressed it, ARDAgent is still unpatched. [Dino Dai Zovi] has published the method by which ARDAgent actually becomes vulnerable: when it starts, it installs its own Apple Event handlers and calls AESetInteractionAllowed() with kAEInteractWithSelf. This should restrict it only to its own events, but for some reason that’s not the resulting behavior. He also pointed out that SecurityAgent has displayed similar weirdness; it is vulnerable to Apple Events even though it doesn’t calls an Apple Events function. We can see how this unexpected behavior could make patch development take much longer and may end up uncovering an even bigger problem. Check out [Dino]’s post for more information.

[Jeff] has been playing around with Parallax’s Propeller chip. He’s used it to adapt an NES controller to the to the Commodore 64. In this latest iteration though, he’s added a Memsic 2125 dual axis accelerometer to the end of a whiffle ball bat and used that to provide Wii style controller input. The video above shows his son playing Street Sports Baseball with it.

Top 10 TEDTalks


The Technology Entertainment Design Conference has been a great source for interesting presentations and in 2006 they started publishing their talks online. This week they published a list of the top 10 most popular talks. There are quite a few tech related ones and we’ve covered some of this work before: [Jeff Han]’s multitouch demos, [Johnny Lee]’s Wiimote hacking, [Blaise Aguera y Arcas] demoing a zoomable interface, and finally for a bit of fun [Arthur Benjamin]’s Mathemagic.
