Spam Archive:

SpamArchive.org is a community resource that provides a database of known spam to be used for testing, developing, and benchmarking anti-spam tools. The goal of this project is to provide a large repository of spam that can be used by researchers and tool developers. In the past, there were a few small personal spam archives that were used. There was no large set of spam that could be used to test new anti-spam algorithms. Thus, developers could not sufficiently test their techniques across a range of messages. Also, the lack of a "standard" sample of spam made it difficult to effectively benchmark anti-spam tools.

The Faster We Go…

The days of the single gigabit backplane are out the door. Today, state-of-the-art systems typically run data rates of 3.125 Gbit/s across 20 inches or more of backplane trace. Next-generation high-end applications are taking these backplane designs even further, moving in the 6.25 Gbit/s and beyond.

At data rates beyond the 1-Gbit/s level, designers must compensate for new problems in their backplane architectures. The signal integrity of these high-speed serial links is affected by reflections due to impedance mismatches along the signal path, signal attenuation from backplane materials, added noise due to crosstalk, and inter-symbol interference.

Patch Your Player:

Security flaws in RealNetworks' media player software could allow attackers to run arbitrary code on a user's computer, the company warned last week. Three vulnerabilities exist in the Windows versions of the RealOne Player and RealPlayer, according to a statement on RealNetworks' Web site. By encouraging a RealOne or RealPlayer user to download a malformed file, an attacker could run code of his choice on a user's system
