Submission + - Learn Gate-Array Programming in Python and Software-Defined Radio 1

Bruce Perens writes: Chris Testa KB2BMH taught a class on gate-array programming the SmartFusion chip, a Linux system and programmable gate-array on a single chip, using MyHDL, the Python Hardware Design Language to implement a software-defined radio transceiver. Watch all 4 sessions: 1, 2, 3, 4. And get the slides and code. Chris's Whitebox hardware design implementing an FCC-legal 50-1000 MHz software-defined transceiver in Open Hardware and Open Source, will be available in a few months. Here's an Overview of Whitebox and HT of the Future. Slashdot readers funded this video and videos of the entire TAPR conference. Thanks!
The Courts

Submission + - Court: Web contracts can't be changed w/o notice->

RZG writes: The U.S. Court of Appeals for the Ninth Circuit ruled on July 18th that contracts posted online cannot be updated without notifying users. "Parties to a contract have no obligation to check the terms on a periodic basis to learn whether they have been changed by the other side", the court wrote. This ruling has consequences for many online businesses, who took for granted their right to do this. (See for example item 19 in Google's Terms of Service)

Space

Submission + - 2 killed in SpaceShipTwo motor test explosion->

RZG writes: Two people were killed and 4 were injured during a "cold fire test" of the motor for SpaceShipTwo. This obviously is a setback for Virgin Galactic and the non-government space community in general. "Aerial video of the blast aftermath showed a charred and twisted flatbed trailer attached to a truck cab with a large silver tank next to it. Large pieces of debris appeared to be strewn for hundreds of yards from the center."
