Reader edgeofphysics provides a technical sidelight on the earthquake in Chile this morning — some details on how the European Southern Observatory protects the mirrors of the Very Large Telescope when an earthquake strikes. "Given that Chile is one of the most seismically active countries in the world, how do astronomers protect their giant telescopes that have been built or are being built in the Chilean Andes? This blog post discusses how Chile's most advanced facility protects its priceless 8.2-meter primary mirrors in the event of an earthquake."

Wescotte writes "There is an important error in most photography scaling algorithms. All software tested has the problem: The Gimp, Adobe Photoshop, CinePaint, Nip2, ImageMagick, GQview, Eye of Gnome, Paint, and Krita. The problem exists across three different operating systems: Linux, Mac OS X, and Windows. (These exceptions have subsequently been reported — this software does not suffer from the problem: the Netpbm toolkit for graphic manipulations, the developing GEGL toolkit, 32-bit encoded images in Photoshop CS3, the latest version of Image Analyzer, the image exporters in Aperture 1.5.6, the latest version of Rendera, Adobe Lightroom 1.4.1, Pixelmator for Mac OS X, Paint Shop Pro X2, and the Preview app in Mac OS X starting from version 10.6.) Photographs scaled with the affected software are degraded, because of incorrect algorithmic accounting for monitor gamma. The degradation is often faint, but probably most pictures contain at least an array where the degradation is clearly visible. I believe this has happened since the first versions of these programs, maybe 20 years ago."

Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."

Lauren Weinstein sends in news of a major and disturbing Microsoft anti-piracy initiative called Windows Activation Technologies, or WAT. Here is Microsoft's blog post giving their perspective on what WAT is for. From Lauren's blog: "The release of Windows 7 'Update for Microsoft Windows (KB71033)' will change the current activation and anti-piracy behavior of Windows 7 by triggering automatic 'phone home' operations over the Internet to Microsoft servers, typically for now at intervals of around 90 days. ... These automatic queries will repeatedly — apparently for as long as Windows is installed — validate your Windows 7 system against Microsoft's latest database of pirated system signatures (currently including more than 70 activation exploits known to Microsoft). If your system matches — again even if up to that time (which could be months or even years since you obtained the system) it had been declared to be genuine — then your system will be 'downgraded' to 'non-genuine' status until you take steps to obtain what Microsoft considers to be an authentic, validated, Windows 7 license. ... KB971033... is scheduled to deploy to the manual downloading 'Genuine Microsoft Software' site on February 16, and start pushing out automatically through the Windows Update environment on February 23. ... [F]or Microsoft to assert that they have the right to treat ordinary PC-using consumers in this manner — declaring their systems to be non-genuine and downgrading them at any time — is rather staggering." Update: 02/12 02:08 GMT by KD : Corrected the Microsoft Knowledge Base number to include a leading 9 that had been omitted in the pre-announcement, per L. Weinstein.

astroengine writes "After 4 years of processing the highest resolution photographs the Hubble Space Telescope could muster, we now have the highest resolution view of Pluto's surface ever produced. Most excitingly, these new observations show an active world with seasonal changes altering the dwarf planet's surface. It turns out that this far-flung world has more in common with Earth than we would have ever imagined."

Epsilon Eridani writes "I am returning to the US after an extended time overseas and upon my return I need to jump head first into the data enabled phone bandwagon. I have to admit ... I am lost as to what is the best company to choose. Before I left the US I used a Sprint HTC phone running Windows with the 'simply everything' plan to communicate and stay organized and a Sprint Wireless Card to connect my laptop to the world. Coming back several generations of technology later, what is the best set up technology-wise to link phone and laptop or two to the Internet? (Open source solutions accepted too!) Can the Slashdot community verify some of the claims on quality of service before I give my first born up when I sign a service contract?"

DeviceGuru writes "Following closely on the heels of the December announcement of D-Link's BoxeeBox, Syabas Technology today said it will ship the PopBox, a $129 Internet-based A/V streaming set-top box (STB) in March. Both new gadgets have the potential to give Roku's popular STB a run for its money. All three boxes can deliver a range of Internet-based A/V streaming and social networking services to consumers' TVs. Like Roku's digital video player STB, the PopBox will include Netflix on-demand video streaming when it first ships. D-Link, meanwhile, is rumored to be scrambling to add Netflix streaming support to its BoxeeBox device as well, prior to inaugural shipments of that device. All three run embedded Linux OSes, and all are expected to sell for less than $200."
