An anonymous reader touts a blog posting up at PC World titled "Trademarks: The Hidden Menace." Keir Thomas asks why open source advocates are keen to suggest patent and copyright reform, yet completely ignore the issue of trademarks, which can be just as corrosive to the freedom that open source projects strive to embody. "Even within the Linux community, trademarking can be used as obstructively as copyright and patenting to further business ends. ... Is this how open source is supposed to work? Restricted redistribution? Tight control on who can compile software and still be able to call it by its proper name? ... Trademarking is almost totally incompatible with the essential freedom offered by open source. Trademarking is a way of severely limiting all activity on a particular product to that which you approve of. ... If an open source company embraces trademarks then it embraces this philosophy. On the one hand it advocates freedom, and [on] the other it takes it away."

We discussed Microsoft making IE8 a critical update a while back; but then the indication was that the update gave users a chance to choose whether or not to install it. Now I Don't Believe in Imaginary Property writes in with word that the update not only does not ask, but it makes IE the default browser. "Microsoft has a new tactic in the browser wars. They're having the 'critical' IE8 update make IE the default browser without asking. Yes, you can change it back, but it doesn't ask you if you want IE8 or if you want it as the default browser, it makes the decisions for you. Opera might have a few more complaints to make to the EU antitrust board after this, but Microsoft will probably be able to drag out the proceedings for years, only to end up paying a small fine. If you have anyone you've set up with a more secure alternative browser, you might want to help check their settings after this."

Binestar was one of several readers writing in to note that Microsoft is listing IE8 as a critical update to Windows XP. CNet reported a couple of weeks back that Microsoft would be rolling our IE8 to users in a gradual fashion, and requiring an opt-in before installing it. Opinion has been split as to whether IE8 is worth installing or not. Binestar notes delicately, "For those not interested in upgrading to IE8 at this time, the MSDN released information back in January on how to keep IE8 off your machine."

CWmike writes "Microsoft's decision to let Windows 7 users run Windows XP applications in a virtual machine may have been necessary to convince people to upgrade, but it could also create support nightmares, analysts said today. Gartner analyst Michael Silver outlines the downsides. 'You'll have to support two versions of Windows,' he said. 'Each needs to be secured, antivirused, firewalled and patched. If a company has 10,000 PCs, that's 20,000 instances of Windows.' The other big problem Silver foresees: Making sure the software they run is compatible with Windows 7. 'This is a great Band-Aid, but companies need to heal their applications,' Silver said. 'They'll be doing themselves a disservice if, because of XPM, they're not making sure that all their apps support Windows 7.'"

Ian Lamont writes "DefectiveByDesign.org is waging a battle against DRM with a 35-day campaign targeting various hardware and software products from Microsoft, Nintendo, and others. On day 11 it blasted iTunes for continuing to use DRM-encumbered music, games, TV shows, movies, audiobooks, and apps with DRM, while competitors are selling music without restrictions. DefectiveByDesign calls on readers to include 'iTunes gift cards and purchases in your boycott of all Apple products' to 'help drive change.' However, there's a big problem with this call to arms: most people simply don't care about iTunes DRM. Quoting: 'The average user is more than willing to pay more money for hobbled music because of user interface, ease of use, and marketing. ... Apple regularly features exclusive live sets from popular artists, while Amazon treats its digital media sales as one more commodity being sold.' What's your take on the DRM schemes used by Apple and other companies? Is a boycott called for, and can it be effective?"

Roland Piquepaille writes "As you probably know, Earth's magnetosphere, 'the invisible bubble of magnetic fields and electrically charged particles that surrounds and protects the planet from the periodically lethal radiation of the solar wind,' was discovered in 1958. Until now, it was believed to comprise five regions, including the ionosphere or the Van Allen radiation belts. Now, a US research team has discovered a sixth region, called the warm plasma cloak."
