Microsoft gets anti-spam support

Microsoft has secured backing from some heavyweights in the messaging-security market, such as Cloudmark, Tumbleweed and VeriSign, after a meeting hosted to spread the news about its Sender ID authentication scheme, according to Information Week.

The report says the meeting was requested by the E-mail Service Provider Coalition made up of e-mail marketing firms trying to get ahead of the spam curve.

Sender ID is a proposed standard for sender authentication aimed at slowing down the spread of spam by validating sender addresses and preventing spammers from forging, or "spoofing" domains. The scheme is a combination of Microsoft`s Caller ID for E-mail and the earlier Sender Policy Framework authored by Meng Weng Wong.

Intel has unveiled a prototype of an IEEE 802.11a wireless LAN transceiver that was created using a 90-nanometre CMOS process.

PC World says the prototype represents a leap of two generations ahead of most current CMOS radio chips, which typically are built at 180-nanometres. As chip structures get smaller, processors tend to get smaller, faster and more power efficient.

Advanced Micro Devices (AMD) has begun to ship processors made on the 90-nanometre process to notebook manufacturers and will start to ship similar chips to desktop manufacturers in a month, reports ZDNet.

The report says the move indicates AMD has mastered many of the problems involved in the production of the new chips. Like some of its competitors, AMD had to postpone 90-nanometre manufacturing several times. These chips were originally supposed to come out at the end of 2003.

Asus has launched what it claims is the industry`s first internal DVD rewriter that enables users to store up to four hours of content on a single disk.

The Asus DRW-1604P supports double layer technology, which doubles media capacity from 4.7GB to 8.5GB, the space required to store four hours of DVD quality video.

Asus says built-in compatibility with both DVD writeable and rewritable formats means the DRW-1604P creates DVDs that can be played or read by most DVD-ROM drives and DVD players.
