Intel Releases 4004 Microprocessor Schematics

Intel Releases 4004 Microprocessor Schematics: "mcpublic writes, 'Intel is celebrating the 35th anniversary of the Intel 4004, their very first microprocessor, by releasing the chip's schematics, maskworks, and users manual. This historic revelation was championed by Tim McNerney, who designed the Intel Museum's newest interactive exhibit. Opening on November 15th, the exhibit will feature a fully functional, 130x scale replica of the 4004 microprocessor running the very first software written for the 4004. To create a giant Busicom 141-PF calculator for the museum, 'digital archaeologists' first had to reverse-engineer the 4004 schematics and the Busicom software. Their re-drawn and verified schematics plus an animated 4004 simulator written in Java are available at the team's unofficial 4004 web site. Digital copies of the original Intel engineering documents are available by request from the Intel Corporate Archives. Intel first announced their 2,300-transistor 'micro-programmable computer on a chip' in Electronic News on November 15, 1971, proclaiming 'a new era of integrated electronics.' Who would have guessed how right they would prove t"

Mutating malware evades detection

Mutating malware evades detection: "Hackers are using increasingly sophisticated methods to ensure that the malware they develop is hard to detect and remove from infected systems, security researchers warned at this week's Computer Security Institute (CSI) trade show. The most popular of these approaches involve code mutation techniques designed to evade detection by signature-based malware blocking tools, code fragmentation that makes removal harder, and code concealment via rootkits. Unlike mass-mailing worms such as MS Blaster and SQL Slammer, most of today's malware programs are being designed to stick around undetected for as long as possible on infected systems, said Matthew Williamson, principal researcher at Sana Security. The goal in developing such malware is not to simply infect as many systems as possible but to specifically steal usage information and other data from compromised systems, he said."

Vista vs Leopard

Vista vs Leopard: "At its recent WWDC (Worldwide Developers Conference), Apple sought to steal some of Microsoft's thunder by releasing just enough details of its next OS (operating system), Leopard, to make an early comparison to the forthcoming Windows Vista possible. Staying true to form, then. It seems as though we've been talking about Vista for ages, and although RC1 (Release Candidate One) came out in September, it's likely to be February before most of us see the finished article. However, its features and general look and feel are fairly common knowledge -- and now we have something tangible to compare it to. Implementation strategies Leopard is an upgrade to Mac OS X, whereas Vista replaces Windows XP almost entirely. Both Apple and Microsoft released OSes in the autumn of 2001 -- Apple's was OS X Puma; Microsoft's was Windows XP. The difference is that XP is still the current version of Windows, while Apple followed up Puma with Jaguar, Panther and Tiger ? Apple has a lots-of-incremental-upgrades philosophy, compared with Microsoft's big-upgrade-once-in-a-blue-moon approach. The t"
