" The top-of-the-line Power Mac G5 with dual 2.5GHz processors squeezes outrageous performance into tight quarters. To cool down those steaming circuits, Apple designed a sophisticated liquid cooling system that takes off the heat without bumping up the noise. Mac OS X dynamically adjusts the flow of the fluid and the speed of the fans based on temperature.

"The dual 2.5GHz Power Mac G5 features an innovative liquid cooling system that’s more efficient than a traditional heat sink. This system provides a continuous flow of thermally conductive fluid that transfers heat from the processors as they work harder. The heated fluid then flows through a radiant grille, where air passing over cooling fins returns the fluid to its original temperature.

"It’s no secret that computers generate heat. So Apple divided the inside of the Power Mac G5 into four discrete thermal zones, compartmentalizing the primary heat-producing components — processor, PCI, storage and power supply. So the system can decrease the temperature of a single zone without affecting the others.

"Each of the four thermal zones is equipped with its own dedicated, low-speed fans. Apple engineered the nine fans to spin at very low speeds for minimum acoustic output. Using 21 different sensors, Mac OS X constantly monitors component temperatures in each zone, dynamically adjusting individual fan speeds to the appropriate levels for the quietest possible operation. As a result, the Power Mac G5 runs two times quieter than the previous Power Mac G4 enclosure."

"In a move that was sure to infuriate Apple, Toshiba let it be known that they will be shipping 60GB models of their 1.8-inch hard drives in July and August, and that Apple is buying them up. Since the only product Apple uses the drives for is the iPod, one can easily connect the dots and see that new, larger-capacity iPods are on the horizon. The larger drive will contain two 30GB platters, an increase from the previous 20GB platter size."

"Two new vulnerabilities have been discovered in Internet Explorer which allow a complete bypass of security and provide system access to a computer, including the installation of files on someone's hard disk without their knowledge, through a single click.

"Worse, the holes have been discovered from analysis of an existing link on the Internet and a fully functional demonstration of the exploit have been produced and been shown to affect even fully patched versions of Explorer.

"It has been rated "extremely critical" by security company Secunia, and the only advice is to disable Active Scripting support for all but trusted websites."

"The two most prominent suppliers of copy protection for music compact disks, are set to come back to the market with rethought offerings whereby CD copying is allowed, but limited to a set number. This strategy, dictated by the record labels as “where they are trying to get,” will emerge in new offerings from market leader Macrovision and SunnComm, during the course of 2004.

"So far, CD copy protection has been crude. It is either on, or it is off. You can either copy as many times as you like, or not copy at all, and the record companies have been terrified of implementing the “copy protection on” mode in sensitive markets. For sensitive markets read the US, primarily, and some parts of Europe.....

"Once they have brought some acceptable form of copy protection to the US, then they will try to bring the same concepts to the online music services of only allowing a set number of CD burns or other copies, for each downloaded track."

"A spectacular 99% drop in Unix licensing revenue for the second quarter of 2004 led overall revenue for Unix vendor The SCO Group Inc. to plunge to $10.1 million for the quarter, which ended April 30. That's down 53% from $21.4 million one year earlier.

"In an announcement today, the Lindon, Utah-based company, which is embroiled in lawsuits with IBM and Novell Inc. over the rights to the Unix operating system and related issues, said the revenue drop was 'primarily the result of a lack of SCOsource licensing revenue' from its SCOsource division....

"After the financial announcement, the company's stock fell. Shortly before the market close today, it was off 10.85%, to $4.85 per share."

"Adobe has released Adobe Acrobat Reader and its Adobe PDF format for a consumer electronics-focused version of Linux....

"Adobe hopes its release will be utilized in a plethora of new consumer electronic devices based on this version of Linux."

"After a week of fevered speculation by Mac fans, Apple on Wednesday updated its Power Mac G5 series of desktop computers with three new dual-processor models.

The new lineup marks a return to Apple's "all-dual" strategy first introduced with the second generation of Power Mac G4s. The company's line now includes a machine featuring two 1.8GHz PowerPC G5 processors, priced at $1999; a mid-range model with two 2.0GHz processors, at $2499; and a high-end model with dual 2.5GHz chips for $2,999."

"TiVo Inc. said Tuesday that it is taking steps toward allowing its PVRs to access content from the Web. The personal-video-recorder company will also allow subscribers access to certain multimedia options it once reserved for premium customers.

TiVo's representatives confirmed that they are working toward a future that will allow their personal-video-recorder devices to access music and movies downloaded from the Internet. Currently, the boxes only allow content to be recorded from television broadcasts, although a Home Media option also allows those recordings to be scheduled via the Internet. Users may also view pictures and listen to music stored on a PC."
