If you plug your power-only USB cable into a modern charger, you'll find that your phone charges quite a bit slower than you'd expect. Modern chargers use the data pins to negotiate whether a charger supports higher currents.

You don't want a phone to try drawing 2A from a charger that's only designed for 500mA.

What's tuggin away at my trouserleg of concern is: How many other experients, with this cable in place, turned out as expected?

Bit of a poser, that one.

Likely none.

My understanding is that the GPS setup was designed specifically for this experiment. Most experiments conducted at the LHC (or Gran Sasso) would be done entirely on-site and therefore don't need a super-accurate global time source.

From what I understand, the Diginotor CRL isn't to be trusted at this point. Logs were deleted as part of the hack, and they're not completely sure which fraudulent certificates were issued.

Their OCSP servers were modified to consider all certificates as revoked, except for those on a whitelist. This is the opposite of how OCSP usually works, and the correct approach in this situation. However, CRLs can only be used as a blacklist.

It makes a big difference for web-based applications that are implemented primarily in JavaScript.

For example: If you're designing slides for a presentation, playing a 3D game, or editing a photo -- things that are graphics heavy and CPU intensive -- you want to get as much performance out of the JS interpreter as possible.


Microsoft In Mobile Search Deal With Verizon 104

An anonymous reader writes "Verizon Wireless will forge a deal with Microsoft to include the software giant's Live Search on its mobile phones, giving Microsoft a victory over rival Google and ending a months-long dance toward the partnership. Microsoft CEO Steve Ballmer will announce the deal in his keynote address at the Consumer Electronics Show in Las Vegas." InfoWorld notes that Microsoft is rumored to be changing the name of its Live Search service to Kumo, which is Japanese for "cloud."

Obama's "ZuneGate" 608

theodp writes "Barack Obama supporters were left shaking their heads after a report surfaced that the president-elect was using a Zune at the gym instead of an iPod. So why would Mac-user Obama be Zune-ing out? Could be one of those special-edition preloaded Zunes that Microsoft bestowed on Democratic National Convention attendees, suggests TechFlash, nixing the idea that the soon-to-be Leader of the Free World would waste time loading Parallels or Boot Camp in OS X just to use a Zune."

Warner Music Pushing Music Tax For Universities 375

Posted by timothy
from the randian-villains dept.
An anonymous reader writes "Warner Music is pitching the idea of a 'music tax' for various top universities. The idea is that students would be free to file share, but the university needs to monitor and track everything, create a pool of money, hand it over to a recording industry entity that promises to distribute the proceeds fairly. In exchange, the university gets a 'covenant not to sue' from the music labels. It's not a full license, just a basic promise that they won't sue. It's also claimed that this is 'voluntary' but the Warner Music guy says that they need to include all universities and all ISPs to really make it work. It's basically a music tax, where the recording industry gets to sit back and collect money."

While I don't mean to dismiss your claim that GSM is more widespread than cdmaOne/CDMA2000, GSM certainly isn't used everywhere outside of the US. For instance, I just returned from a trip to Japan, and there is no GSM installation there. Instead, there's a mix of cdmaOne/CDMA2000, W-CDMA, PDC, and PHS.

bartv writes "Blender 2.42 has been released. It features an impressive list of new features for professional users. The most important improvements are: a new render pipeline, node editors for compositing and materials, support for anisotropic materials, improved fluid simulation and new character animation tools. Most of these features are the result of the production of Elephants Dream, the first Open Movie. During this project, Blender's lead developer Ton Roosendaal was coding the features that were required by the artists to produce their movie."

ACLU Files for Info on New Brain-Scan Tech 257

from the also-requesting-information-on-psychics dept.
An anonymous reader writes "According to their website, the ACLU has filed a FOIA request seeking information on the new Functional Magnetic Resonance Imaging service being made available to the government for use on suspected terrorists which can produce 'live, real-time images of people's brains as they answer questions, view images, listen to sounds, and respond to other stimuli. [...] These brain-scanning technologies are far from ready for forensic uses and if deployed will inevitably be misused and misunderstood," said Barry Steinhardt, Director of the ACLU's Technology and Liberty Project. "This technology must not be deployed until it is proven effective -- and we are a long way away from that point, according to scientists in the field,"'"

Computers can figure out all kinds of problems, except the things in the world that just don't add up.
