The impact created a huge splash as seen on the video, but the impact at the surface was blocked by an occluding disk that allows the SDO to image the sun's corona. It's still very impressive though!"

We're not trying to use these calculators to cheat on tests. We're trying to use them as programmable devices that we bought and that we can develop. Many people learned computer programming starting from simple programs on calculators. There is already a large community of TI calculator developers (not affiliated with TI). If anyone used external software to cheat, that'd be their problem, not ours.

Deep Thought writes: Texas Instruments, already infamous thanks to the signing key controversy last year, is trying a new trick to lock down its graphing calculators, this time directed toward its newest TI-Nspire line. The TI-Nspires were already the most controlled of TI's various calculator models, and no third-party development of any kind (except for its very limited form of TI-BASIC) was allowed until the release of the independent tool Ndless. Since its release, TI has been determined to prevent the large calculator programming community from using it. Its latest released operating system for the Nspire family (version 2.1) now prevents the calculators from downgrading to OS 1.1, needed to run Ndless. This is the TI's second major attack on Ndless, as the company has already demanded that websites posting the required OS 1.1 be removed from public download, obviously to prevent use of the tool. Once again, TI is preventing calculator hobbyists from running their own software on calculators they bought and paid for. Is TI going the way Apple did?

Submission + - Microsoft Has No Plans to Patch New Flaw (threatpost.com)

Trailrunner7 writes: Microsoft has acknowledged the vulnerability that the new malware Stuxnet uses to launch itself with .lnk files, but said it has no plans to patch the flaw right now. The company said the flaw affects most current versions of Windows, including Vista, Server 2008 and Windows 7 32 and 64 bit.
Meanwhile, the digital certificate that belonging to Realtek Semiconductor that was used to sign a pair of drivers for the new Stuxnet rootkit has been revoked by VeriSign. The certificate was revoked Friday, several days after news broke about the existence of the new malware and the troubling existence of the signed drivers. Stuxnet is an odd case. It is spread via infected USB thumb drives, which contain the rootkit code, along with two drivers that researchers say are used to hide the existence of the malware both on the USB drive and on the PC, once it's infected. The drivers are signed using a valid digital certificate owned by Realtek, a Taiwanese hardware manufacturer, and Stuxnet uses .lnk shortcut files to launch as soon as the USB drive is opened on a PC.
