Comment Re:Don't be a jerk (Score 1) 64

I'm no sociologist, but... Social groups with something in common usually has unwritten rules that can be summarized as "Don't be a jerk". As the community grows and more people, and therefore more jerks, join. The social control in the group loosens and a bigger need for a formalized set of rules emerge. I congratulate the OSHW movement for, by this article, taking the first steps towards formalizing their rules, and becoming a more jerk friendly (or unfriendly depending on how you see it) community.

Comment Re:How much would better cooling cost? (Score 1) 303

Well, the stirling engine requires a large temperature difference between a hot and cold medium. And will essentially need some kind of cooling source to operate. Stirling engines usually has a maximum efficiency of ~40% (number grabbed from the back of my head, don't take it too seriously) wich means that more than 60% of the heat energy will end up heating the cooling medium. Also, the mechanical energy generated by the stirling engine will turn into heat sooner or later due to the grim laws of thermodynamics.

Submission + - Nmap 5.00 Released! (nmap.org)

iago-vL writes: "The long-awaited Nmap Security Scanner version 5.00 was just released (download)! This marks the most important release since 1997, and is a huge step in Nmap's evolution from a simple port scanner to an all-around security and networking tool suite. Significant performance improvements were made, and dozens of scripts were added. For example, Nmap can now log into Windows and perform local checks (PDF), including Conficker detection. New tools included in 5.00 are Ncat, a modern reimplementation of Netcat (with IPv6, SSL, NAT traversal, port redirection, and more!), and Ndiff, for quickly comparing scan results. Other tools are in the works for future releases, but we're still waiting for them to add email and ftp clients so we can finally get off Emacs!"

Submission + - New Binary Diffing Algorithm Announced by Google

bheer writes: "Google's Open-Source Chromium project announced a new compression technique called Courgette geared towards distributing really small updates today. Courgette achieves smaller diffs (about 9x in one example) than standard binary-diffing algorithms like bsdiff by disassembling the code and sending the assembler diffs over the wire. This, the Chromium devs say, will allow them to send smaller, more frequent updates, making users more secure. Since this will be released as open source, it should make distributing updates a lot easier for the open-source community."
