linuxwrangler writes: Security researcher Jack Loius, who had discovered several serious security flaws in TCP software was killed in a fire on the ides of March dealing a blow to efforts to repair the problem. Although he kept good notes and had communicated with a number of vendors, he died before fixes could be created and prior to completing research on a number of additional vulnerabilities. Much of the work has been taken over by Louis' friend and long-time colleague Robert E. Lee. The flaws have been around for a long time and would allow a low-bandwidth "sockstress" attack to knock large machines off the net.

Microbiologist Bonnie Bassler here explains her discovery of "quorum sensing" — the amazing ability of bacteria to communicate with each other and coordinate attack strategies. By cracking the communication code, she has opened up potential for a new class of drugs tackling microbial diseases. The talk got a massive standing ovation at this year's TED and has just been posted. To quote one commenter: "This is by far the most inspiring, amazing, and far-reaching talk I've seen in a very long time. " Wd love Slashdot community's insight into implications of this work."

High monthly costs, management, and room setup continue to deter companies from deploying telepresence, which if rolled out in earnest stands to cut down significantly on the overall carbon footprint of business. 'The initial setup costs of a telepresence system in two locations equals about 350 one-night trips per room over the lifetime of the telepresence rooms, and the monthly fees equal about 20 one-night trips per month,' InfoWorld reports. Put in other terms, a telepresence system must be used 25 percent of the business day to justify its investment, analysts contend. But interoperability may be the chief hurdle to realizing the environmental upsides of telepresence, as major vendors' appear to be moving slow to standardize their systems to be interoperable with one another, and with the kind of commodity components that will make telepresence affordable on a wide scale."

The important distinction between this and other iPhone unlocking methods is that it requires less hardware, and allows you to continue to use EDGE with the new SIM card.

Some researchers funded by Intel over at Purdue have improved the "heat-transfer coefficient" by some 250%. I never liked water cooled systems, and this sounds promising. However I wonder how much ozone one of these things produces, probably not much.
