Minecraft Mod Adds Emulated 6502 Processor
New submitter Direwolf20 writes "The Red Power 2 mod for Minecraft has recently been updated, and it adds a fully emulated 6502 processor that can be programmed in assembly, but comes with a Forth interpreter. From the article: 'Eloraam calls it the 65EL02, because "it supports all the 6502, 65C02, and part of the 65C816 instruction set" as well as "a set of completely new instructions and two addressing modes. Since the 65EL02 is an 8-bit CPU, Eloraam didn't have as many options for programming environments as we have on today's 64-bit computers. While it's possible to program the 65EL02 in assembly language, for general use she chose to implement a Forth interpreter. Further technical information about RedPower Control's 65EL02 is available on Eloraam's blog RP Control Internals, and on the RedPower wiki's page for Red Power Control.'

Using the Web To Turn Kids Into Autodidacts
theodp writes "Autodidacticism — self-education or self-directed learning — is nothing new, but the Internet holds the promise of taking it to the masses. Sugata Mitra, an Indian physicist whose earlier educational experiments inspired the film Slumdog Millionaire, is convinced that, with the Internet, kids can learn by themselves so long as they are in small groups and have well-posed questions to answer. And now, Mitra's Self-Organized Learning Environments (SOLE) are going global, with testing in schools in Australia, Colombia, England and India. On their own, children can get about 30% of the knowledge required to pass exams, so to go further, Dr. Mitra supplements SOLE with e-mediators, amateur volunteers who use Skype to help kids learn online." -

British Computer Society Is Officially At Civil War
An anonymous reader writes "A vote of no confidence against the current board of directors has erupted in what is possibly the first nerd war, raging throughout the British Computer Society. More financial- and spreadsheet-related fixations and less computer science have made a few members cross; plus they don't like the new name 'The Chartered Institute of IT.' Here are more specific details on the extraordinary emergency general meeting on July 1, where members will vote to decide the fate of the board of directors." -
Sequoia Voting Systems Source Code Released
Mokurai sends a heads-up about Sequoia Voting Systems, which seems to have inadvertently released the SQL code for its voting databases. The existence of such code appears to violate Federal voting law: "Sequoia blew it on a public records response. ... They appear... to have just vandalized the data as valid databases by stripping the MS-SQL header data off, assuming that would stop us cold. They were wrong. The Linux 'strings' command was able to peel it apart. Nedit was able to digest 800-MB text files. What was revealed was thousands of lines of MS-SQL source code that appears to control or at least influence the logical flow of the election, in violation of a bunch of clauses in the FEC voting system rulebook banning interpreted code, machine modified code and mandating hash checks of voting system code." The code is all available for study or download, "the first time the innards of a US voting system can be downloaded and discussed publicly with no NDAs or court-ordered secrecy," notes Jim March of the Election Defense Alliance. Dig in and analyze. -
Amiga Community Collaborates On Restorative Gel To Brighten Your Old Plastic
jamie pointed out an Amiga community that took a discovery of how to restore old computer plastic, super-charged it, and then opened the process to the public domain. Time to spruce up those old dusty TRS-80s in the basement. "All of the initial tests were done with a liquid and we realized that for large parts this was getting expensive, so the next stage was to make a paintable 'gel' version that could be brushed onto larger surfaces. This was tried in Arizona in the sun and the UK under a UV lamp and was found to be just as effective as the liquid. We have now released this to the public domain for anyone to use as we can't patent it and we coined the nickname 'Retr0brite' for it, as it summed up what we were actually doing with it." -
An Open Source Hardware Development Tool
LuxuryYacht writes "The PLAICE is an open source hardware and software project developing a powerful in-circuit development tool that combines in one device the features of a FLASH Programmer, Memory Emulator, and High Speed Multi-Channel Logic Analyzer. It runs uClinux. The logic analyzer features up to 200MHz sampling rates and up to 32 input channels. The logic analyzer Java client supports up to 200MHz sampling rates, user-controlled filtering operations, time line in diagrams, transfer rates, and user configurable drawing modes. The Java client supports access via almost any PC with a serial port and uses the RXTX serial library with support for 34 platforms including Linux, Windows, and Solaris. Java client plugins include an SPI and I2C bus protocol analyzer, conversion of timing analysis to state analysis, and post-processing functions."
