Hugh Pickens writes "Launched in May, BBC reports that Europe's Planck observatory has reached its operating temperature, a staggering minus 273.05C — just a tenth of a degree above what scientists term "absolute zero." and although laboratory set-ups have got closer to absolute zero than Planck, researchers say it is unlikely there is anywhere in space currently that is colder than their astronomical satellite. This frigidity should ensure the bolometers will be at their most sensitive as they look for variations in the temperature of the Cosmic Microwave Background (CMB) that are about a million times smaller than one degree — comparable to measuring from Earth the heat produced by a rabbit sitting on the Moon. Planck has been sent to an observation position around the second Lagrange point of the Sun-Earth system, L2, some 1.5 million km from Earth and Planck will help provide answers to one of the most important sets of questions asked in modern science — how did the Universe begin, how did it evolve to the state we observe today, and how will it continue to evolve in the future. Planck's objectives include mapping of Cosmic Microwave Background anisotropies with improved sensitivity and angular resolution, determination of the Hubble constant, testing inflationary models of the early Universe, and measuring amplitude of structures in Cosmic Microwave Background. 'We will be probing regimes that have never been studied before where the physics is very, very uncertain,' says Planck investigator Professor George Efstathiou from Cambridge University. 'It's possible we could find a signature from before the Big Bang; or it's possible we could find the signature of another Universe and then we'd have experimental evidence that we are part of a multi-verse.'"

Harry writes "In 1968, computers tended to occupy entire rooms, and were therefore hard to take with you. But Computerworld reports on Anderson Jacobson's 75-pound Teletype-terminal-in-a-case, an early attempt to let folks compute from anywhere. (Well, anywhere they had power and access to a telephone for the Teletype's acoustic coupler.) Wheels were optional."

Slatterz writes "The Tesla Roadster has almost mythical status among electric car enthusiasts. It's fast, with high torque over a wide RPM range, and can beat a Ferrari in terms of acceleration. Now Tesla has released new video of its upcoming new electric car, called the Model S, which Tesla Motors claims is the world's first mass produced fully-electric vehicle. Unlike the Lotus-Elise based Roadster, the Model S is a traditional sedan of the type millions of commuters might actually drive. Tesla claims it will fit seven people (if two of them are "children under 10"), and has mounted a rather large 17in LCD in the dash. Key to Telsa's future will be the evolution of lithium-ion battery technology. Tesla Motors claiming the new Model S can travel up to 300 miles on a single charge, but the battery will still take 45 minutes to quick-recharge." (And for those in countries where it matters, this article mentions that it should also be available in right-hand drive.)

It's gonna take a long time to find anything that way.

An anonymous reader writes "A new Canadian study deconstructs how copyright lobby groups manipulate public opinion by laundering proposals through seemingly independent groups. The study started after the Conference Board of Canada was shown to have plagiarized several of its IP reports and now shows the connections that all lead through the MPAA and RIAA. Michael Geist writes, 'It is not just that these reports all receive financial support from the same organizations and say largely the same thing. It is also that the reports each build on one another, creating the false impression of growing momentum and consensus on the state of Canadian law and the need for specific reforms.'"

There has been a lot of comments both on this blog and the internals list. There seems to be a fairly large group of core developers who like the idea as well as surpassingly large support base on the user level too (wow, didn't think that this many people want type hinting). Unfortunately, there have also been, as is typically on the internals list a few people complaining for the sake of complaining. Their arguments have ranged from type hinting is against PHP's loosely typed nature and people will mis-use it and make PHP into something that it is not, to I don't need or will use it, so no one should get it.

That said these people are in the minority, albeit a rather vocal one, so progress is being made. There have also been a number of really good suggestions by folks who have reviewed the patch (big thanks guys) and their improvements have been incorporated into the version 2 of the patch. Here is the quick changelog.

1) Added support for "object" type hint
2) Modified the patch not to break binary compatibility so you can now use patched PHP without having to re-compile your extensions or having issues with binary ones.
3) Added full reflection support, which I appropriated from Felipe's earlier work on type hinting
4) Added support for type casting, where by you can do things like this function a((int)$foo), which will force PHP to cast the value of $foo to an integer
5) Added tests, which again I partially appropriated from Felipe's earlier work.

The updated patch is available here: http://ilia.ws/patch/type_hint_53_v2.txt
The mini test suit which can also show practical examples & limitations of the functionality can be found here: http://ia.gd/patch/type_hint_tests.tar.bz2

I am posting it here for peer review and comment. If all goes well, I am going to post it to internals for a vote, which will hopefully pass. So, if you want the feature in, or you think its crap, watch internals on Monday so you can make your opinion known via a +/- vote.

Oracle Goddess writes "After 30 years, CompuServe is all but dead, as AOL has pulled the plug on the once-great company. The original CompuServe service, first offered in 1979, provided its users with addresses such as 73402,3633 and was the first major online service. CompuServe users will be able to use their existing CompuServe Classic (as the service was renamed) addresses at no charge via a new e-mail system, but the software that the service was built on has been shut down. Tellingly, the current version of the service's client software, CompuServe for Windows NT 4.0.2, dates back to 1999."

Australian scientists today unveiled three new dinosaur skeletons, excavated from Queensland---two herbivores and one carnivore which roamed the land about 98 million years ago, one of the most significant discoveries in decades.

Hugh Pickens writes "TechCrunch's Michael Arrington has been talking for a year about building a touch-screen tablet for Web surfing and now it appears that the CrunchPad is close to becoming a reality. 'We're going to make some really big announcements,' said Arrington, who predicted a prototype would be ready for unveiling by the end of July. The purpose of the CrunchPad will be very simple: surfing the Web. Turn it on and up comes a browser — 'an Internet consumption device,' for reading, checking e-mail or watching video. The CrunchPad will not have a hard drive or keyboard and photos of the latest prototype show a device with a 12 inch screen. 'The screen is now flush with the case and we've decreased the overall thickness to about 18 mm,' writes Arrington. 'The case will be aluminum, which is more expensive than plastic but is sturdier and lets us shave a little more off the overall thickness of the device.' The CrunchPad boots directly into the browser with a Linux-based operating system and a WebKit-based browser. A video of an earlier CrunchPad prototype in action shows a device which, unlike the iPhone, runs flash. 'The next time we talk about the CrunchPad publicly will be at a special press and user event in July in Silicon Valley,' writes Arrington. 'We're full on. These prototypes are real.'"
