Examining the Objective-C runtime information stored in Mach-O files

class-dump
This is a command-line utility for examining the Objective-C runtime information stored in Mach-O files. It generates declarations for the classes, categories and protocols. This is the same information provided by using ‘otool -ov’, but presented as normal Objective-C declarations, so it is much more compact and readable.
Why use class-dump?
It’s a great tool for the curious. You can look at the design of closed source applications, frameworks, and bundles. Watch the interfaces evolve between releases. Experiment with private frameworks, or see what private goodies are hiding in the AppKit. Learn about the plugin API lurking in Mail.app.

The iPodTouch Is What The OLPC XO Should Have Been

The iPodTouch is a mass-marketed device, so its cost has been driven down. An 8Gb device costs only $230.
Its development environment nearly demands performance. Its development language is Objective-C or C and only one app can be run at a time. Contrast that with Sugar on X11 on Python on C and an environment that exhausts available memory with very little effort.
Its touch screen encourages interaction. The XOs flakey keyboard and touchpad discourage it.
I still love the XO and OLPC’s mission. The only thing that they seem to have accomplished, though, is the proliferation of Netbooks across the commercial landscape.

R6RS Scheme Libraries project and team

In this thread, Derrick explains the purpose of the group:

The intent is to organize arbitrary Scheme libraries, which aren’t already part of a project, in one place and to provide a place to report and track bugs and questions about these libraries.

Pi Cubed

Pi Cubed is a visual math application for the iPhone / iPod touch that lets you perform calculations as you would on a piece of paper.

This app looks very interesting both in the problem that it solves and how it allows you to do so.
