"The HTML file that contains all the text for this article is about 25000 bytes. That's less than one of the image files that was also downloaded when you selected this page. Since image files typically are larger than text files and since web pages often contain many images that are transmitted across connections that can be slow, it's helpful to have a way to represent images in a compact format. In this article, we'll see how a JPEG file represents an image using a fraction of the computer storage that might be expected. We'll also look at some of the mathematics behind the newer JPEG 2000 standard."

The vaunted 'USD 100 laptop' that Massachusetts Institute of Technology researchers dreamed up for international schoolchildren is becoming a slightly more distant concept. The USD 100 laptop has many innovative features including a pull cord for recharging by hand. Leaders of the nonprofit One Laptop Per Child that was spun out of MIT acknowledged Friday that the devices are now slated to cost USD 188 when mass production begins this fall. The last price the nonprofit announced was USD 176; it described USD 100 as a long-term goal.

Microsoft has begun patching files on Windows XP and Vista without users' knowledge, even when the users have turned off auto-updates. Many companies require testing of patches before they are widely installed, and businesses in this situation are objecting to the stealth patching. "Normal behaviour," according to Microsoft.

"Ubuntu sponsor Canonical announced a version of its Linux software stripped down for use just on virtualized environments. The version, called Jeos for 'Just Enough Operating System' and pronounced 'juice', is now available." That's what ZDnet and News.com report, but Jeos is nowhere to be found on the Ubuntu website. El Reg claims: "Canonical is still in the midst of deciding whether not to make JeOS wildly available, since it's mostly meant as an ISV thing."

The widespread acceptance of open source continues to grow as a cost-effective alternative to traditional network deployments. Well-known projects such as Linux have proven themselves to be in the enterprise environment, helping to dispel the fear, uncertainty and doubt preceding open source implementations. In the past two years, the industry has begun to shift from a total dependence on proprietary applications to a desire for more cost-effective, scalable and collaborative solutions.

Having recently rediscovered itself as a systems company, Sun Microsystems has been welcomed into Microsoft's vast and growing family of OEM partners. Expanding the companies' three-year-old interoperability pact, Sun has agreed to ship Microsoft's dated but important Windows Server 2003 operating system pre-installed on its x64 machines. The companies will also co-operate on go-to-market activities for the machines. Ars Technica has more.
