Ostracus writes "It sounds like science fiction, but scientists say it might one day be possible to erase undesirable memories from the brain, selectively and safely. After exposing mice to emotionally powerful stimuli, such as a mild shock to their paws, the scientists then observed how well or poorly the animals subsequently recalled the particular trauma as their brain's expression of CaMKII was manipulated up and down. When the brain was made to overproduce CaMKII at the exact moment the mouse was prodded to retrieve the traumatic memory, the memory wasn't just blocked, it appeared to be fully erased."

UniversalVM writes "What is the single biggest issue that bothers open source advocates about proprietary software? It is probably the ability of the vendor to pull stunts like Microsoft's recent stealth software update and subsequent downplaying of any concerns. Their weak explanation seems to be a great exercise in circular logic: 'Had we failed to update the service automatically, users would not have been able to successfully check for updates and, in turn, users would not have had updates installed automatically or received expected notifications.' News.com is reporting that all of the updated files on both XP and Vista appears to be in windows update itself. This is information that was independently uncovered by users and still not released by Microsoft."

mateuscb writes "A few years ago, social networking Web sites were just some newfangled technology that college students loved. But over time, they have metamorphosed into an unavoidable Internet phenomenon that is changing the way people of all ages keep in touch with friends, find long-lost acquaintances, explore new hobbies and even look for employment."

Several readers sent in a link to an op-ed in the NYTimes by novelist Mark Halprin, who lays out the argument for what amounts to perpetual copyright. He says that anything less is essentially an unfair public taking of property: "No good case exists for the inequality of real and intellectual property, because no good case can exist for treating with special disfavor the work of the spirit and the mind." This community can surely supply a plethora of arguments for the public domain, words which don't appear in the op-ed. In a similar vein, reader benesch sends us to the BBC for a tale of aging pop performers (virtually) serenading Parliament in favor of extending copyright for recording artists in the UK. Some performers are likely to outlive the current protections, now fixed at a mere 50 years.

Ant writes "In Scott Dunn's Windows Secrets, he describes his informal tests of well-known computer security vendors when it comes to subscriptions and renewals. These days, most antivirus and other security products come with a subscription to update your virus definitions. He also explains ways to opt-out, users' comments, etc. Seen in EGeezer's Broadband/DSL Reports security forum thread. Always read those end user license agreements (EULAs)."

J.R writes "The Security-Hacks blog has a summary of the 15 best free SQL Injection scanners, with links to download and a little information about each one. The list is intended asan aid for both web application developers and professional security auditors."

An anonymous reader writes "The firmware of the Xbox 360 DVD drive has been hacked, allowing users to boot backups of games on the new Microsoft console. A group of hackers on the xboxhacker.net forum managed to trick the DVD firmware into reporting a recordable disc as an original Xbox 360 disc. This means that it will not allow booting of unsigned homebrew code (like Linux), as the signature check is not bypassed. This hack will just trick the Xbox 360 into thinking you inserted an original Xbox 360 disc, so it'll only boot unedited executables. A video has been released, the hack has not been released to the public (because it will be mainly used for piracy), but all the research of the last few months is publicly viewable."

Robert wrote to mention a Computer Business Review Online article about SCO's newest marketing tactic. They're offering their OS as part of a 'SCAMP' stack, ala the more familiar LAMP setup. From the article: "The Lindon, Utah-based Unix vendor has included the open source Apache web server, MySQL database, and PHP and Perl programming languages with its SCO OpenServer operating system since the launch of OpenServer 6 in June 2005. It is now pitching the technologies as a SCAMP stack, placing it squarely up against the Linux-based LAMP stack. SCO claims that Linux contains Unix code donated to the open source operating system in violation of agreements between it and IBM Corp."
