    I’m really sorry about the continuous Windows security reports but they just keep on coming so what else can I do… Data Execution Prevention is a security tool that Microsoft added to all versions of Windows since XP SP2.

    I’ve been running Slackware-current ( the development version of Slackware ) for probably close to 5 years now. For the most part, it’s a pretty uneventful stream of upgrades however, every once in a while things get interesting.

    The US Copyright Lobby has indicated that using FOSS equates to the undermining of intellectual property rights. Yes you read that correctly. They want the US Trade Representative to place countries like Brazil, India, and Indonesia on the Special 301 list, which is a list of countries that do not, according to mostly the Pharmaceutical…

    While I’ve never assumed AV software will protect you from all ills on the Internet, new research from SurfRight shows just how bad things are. A sample of just under 110k users ( a very good sample I think ) shows that 32% ( yes 1/3rd ) of all machines running AV software were infected…
