CowboyRobot writes "The creators of the Lua language describe the process of designing a new language and the constraints that certain parameters, specifically embeddability, place on the process. 'Many languages (not necessarily scripting languages) support extending through an FFI (foreign function interface). An FFI is not enough to allow a function in the system language to do all that a function in the script can do. Nevertheless, in practice FFI covers most common needs for extending, such as access to external libraries and system calls. Embedding, on the other hand, is harder to support, because it usually demands closer integration between the host program and the script, and an FFI alone does not suffice.'"

Steve1960 writes "Amazon.com chief Jeff Bezos says the online retailer won't collect tax from most of its 90 million customers until Congress clearly mandates it. Although a growing number of states are demanding that Amazon collect and remit tax on sales within their borders, such demands are 'interference in interstate commerce' and prohibited by the Constitution, Bezos said."

An anonymous reader writes "The Canadian music industry's copyright collective is demanding the creation of a new copying tax on all memory cards sold in Canada. The Canadian Private Copying Collective has filed for a tax of up to $3 per memory card to compensate for music copying on SD cards. If approved, the tax could cost consumers millions of dollars." Makes no less sense than the current levy exacted on blank CDs and audiotapes in Canada — and no more sense, either.

eldavojohn writes "LimeWire has settled its suit with the RIAA for $105 million. It's several orders of magnitude lower than the $1.5 trillion initially demanded by the RIAA, but it ends a nearly five-year legal battle. P2P networks take heed; the monster may start looking for other targets."

An anonymous reader writes "Today most applications that require accurate atomic clock readings — from sorting separately routed telecommunications packets to timing simultaneous demolition charges — usually refer to signals from global positioning systems (GPS). For applications where GPS is unavailable, such as indoors, underground, undersea or on the battlefield where electronic jamming is present, large, heavy, power hungry hardware atomic clocks were needed. Now an atomic clock-on-a-chip is available that is the result of 10 years of government-funded research and development. The chip is not cheap — $1,500 — but it costs less than conventional atomic clocks and the price is sure to go down as manufacturing gears up to meet demand from military applications."

Julie188 writes "Researchers are warning that the WebGL standard undermines existing operating system security protections and offers up new attack surfaces. To enable rendering of demanding 3D animations, WebGL allows web sites to execute shader code directly on a system's graphics card. This can allow an attacker to exploit security vulnerabilities in the graphics card driver and even inject malicious code onto the system."

itwbennett writes "The IEEE has formed a group to assess demand for a faster form of Ethernet, taking the first step toward what could become a Terabit Ethernet standard. 'We all contacted people privately' around 2005 to gauge the need for a faster specification, said John D'Ambrosia, chairman of the new ad hoc group. 'We only got, like, seven data points.' Disagreement about speeds complicated the process of developing the current standard, called 802.3ab. Though carriers and aggregation switch vendors agreed the IEEE should pursue a 100Gbps speed, server vendors said they wouldn't need adapters that fast until years later. They wanted a 40Gbps standard, and it emerged later that there was also some demand for 40Gbps among switch makers, D'Ambrosia said. 'I don't want to get blindsided by not understanding bandwidth trends again.'"

CWmike writes "LastPass on Friday rescinded its day-old order that all users of its online password management system reset their master passwords due to a database breach. In a blog post this morning, the company said it won't allow users to change master passwords 'until our databases are completely caught up and we have resolved outstanding issues.' In an e-mail to Computerworld, LastPass CEO Joe Siegrist said the company changed its plan in response to demands from users asking they not be required to reset their passwords. However, comments posted on a LastPass blog suggest that the company's decision may also be related to trouble some users appear to be having with the password reset process. The blog post acknowledged that it had 'identified an issue' with roughly 5% of users that reset their master passwords. The company said it would be contacting those users about a fix for the problem LastPass said earlier that passwords for its Xmarks bookmark sync, which it acquired last December, were not affected."

An anonymous reader writes "With the release of the dual-GPU AMD Radeon HD 6990, closely followed by the competing Nvidia GeForce GTX 590, we saw graphics card performance reach new heights. With bandwidth throughput in excess of 300GB/s, these cards can consume more power than entire computer systems. By utilizing three monitors, games can become roughly 3x more demanding, as the graphics card is required to render an overwhelmingly higher number of pixels. Whereas graphics card reviews and benchmarks usually test GPUs at single monitor resolutions, TechSpot has added two more LCD monitors and tested eleven games running at resolutions of 5040x1050, 5760x1200 and 7680x1600."

eldavojohn writes "You're probably familiar with Microsoft's long running assault on Android but, as noticed by Groklaw, Barnes and Noble has fired back saying, 'Microsoft has asserted patents that extend only to arbitrary, outmoded, or non-essential design features, but uses these patents to demand that every manufacturer of an Android-based mobile device take a license from Microsoft and pay exorbitant licensing fees or face protracted and expensive patent infringement litigation.' Barnes and Noble goes on to assert that Microsoft violates 'antitrust laws, threatens competition for mobile device operating systems and is further evidence of Microsoft's efforts to dominate and control Android and other open source operating systems.' The PDF of the filing from two days ago is rife with accusations including, 'Microsoft intends to utilize its patents to control the activities of and extract fees from the designers, developers, and manufacturers of devices, including tablets, eReaders, and other mobile devices, that employ the Android Operating System.' and 'Microsoft has falsely and without justification asserted that its patents somehow provide it with the right to prohibit device manufacturers from employing new versions of the Android Operating System, or third party software.' Barnes and Noble does not mince words when explaining Microsoft's FUD campaign to both the public and developers in its attempts to suppress Android. It's good to see PJ still digging through massive court briefs to bring us the details on IP court battles."

Hugh Pickens writes "Copyright troll Righthaven makes their money by coercing defendants of alleged copyright infringement into settling with them with threats of $150,000 in damages and forfeiture of the defendants' website domain names. Now EFF reports that Chief Judge Hunt of the federal court in Nevada, which is overseeing more than 200 Righthaven copyright cases, has dismissed Righthaven's merit-less claim to seize its victim's domain names. Righthaven contended that the mere hosting of any infringing material meant that the entire domain name was forfeit but the judge rejected that claim, explaining that the 'Court finds that Righthaven's request for such relief fails as a matter of law and is dismissed.' But now Righthaven has filed a new copyright case in Nevada federal court that not only demands forfeiture of the domain name but has asked the Court to 'order the surrender to Righthaven of all hardware, software, electronic media and domains, including the Domain used to store, disseminate and display the unauthorized versions of any and all copyrighted works.' The new complaint also asserts that Righthaven holds the 'exclusive rights' to Stephens Media news articles, despite the Strategic Alliance Agreement showing that Stephens Media retains these rights."

dgilzz writes "The Japanese government says that the damage caused by earthquakes and by the nuclear accident are being magnified by irresponsible rumors, and the government must take action for the sake of the public good. The project team has begun to send letters of request to such organizations as telephone companies, internet providers, cable television stations, and others, demanding that they take adequate measures based on the guidelines in response to illegal information. The measures include erasing any information from internet sites that the authorities deem harmful to public order and morality."

An anonymous reader writes "Apple's iPhone 3G, iPhone 3GS, the iPhone 4, and iPad models are keeping track of consumers whereabouts. Mac computers running Snow Leopard and even Windows computers running Safari 5 are being watched. But the question is why? 'To provide the high quality products and services that its customers demand, Apple must have access to the comprehensive location-based information,' Apple says."

Several readers have sent in follow-up articles to Wednesday's news that iPhone location data was being tracked and stored. First, it seems Android shares a similar problem, though the file containing the location data is "only accessible on devices that have been rooted and opened up to installation of unsigned apps." Developer Magnus Eriksson has created an app to flush this data. Next: the iPhone tracking file is not new, just in a different place than it used to be. Reader overThruster then points out a CNet story indicating that law enforcement has been aware of this file for some time, and has used it in a forensics context. This story is a growing concern for Apple, particularly now that Senator Al Franken (PDF) and Rep. Ed Markey (PDF) have both written letters to Steve Jobs demanding details about the location tracking. Finally, PCMag explains how to view the location data present on your iPhone, should you so desire.

SonicSpike writes "The Michigan State Police have a high-tech mobile forensics device that can be used to extract information from cell phones belonging to motorists stopped for minor traffic violations. The American Civil Liberties Union (ACLU) of Michigan last Wednesday demanded that state officials stop stonewalling freedom of information requests for information on the program. A US Department of Justice test of the CelleBrite UFED used by Michigan police found the device could grab all of the photos and videos off of an iPhone within one-and-a-half minutes. The device works with 3000 different phone models and can even defeat password protections. 'Complete extraction of existing, hidden, and deleted phone data, including call history, text messages, contacts, images, and geotags,' a CelleBrite brochure explains regarding the device's capabilities." Popular Mechanics has a short conversation with a 4th Amendment lawyer about the practice of slurping cellphone data, too, though it's unclear if the Michigan police are actually using these devices to their full potential.

jfruhlinger writes "For some time there's been rumbling that Google's search results have been gummed up by low-quality pages from 'content farms,' written at low or no cost specifically to score high on common Google queries. Now it looks like the latest update to Google's search algorithm is having an effect, cutting into traffic to eHow (and cutting down the stock price of eHow's owner, Demand Media, in the process)."

An anonymous reader writes "A fellow art student of mine (yes, there are artists on Slashdot as well) has been sued by Louis Vuitton for depicting one of their bags in her painting. Her painting is wholly original, however LV is demanding 5,000 euros a day because the 'pattern of this bag infringes its design rights,' and for her to cease displaying her original artwork on her website. It might be preaching to the choir here on Slashdot, but these cases need all the attention they can get."

vasanth writes "Two new initiatives at the University of Cambridge aim to address the growing demand on the Earth's resources for food and fuel by improving the process of photosynthesis. Four transatlantic research teams – two of which include academics from Cambridge's Department of Plant Sciences – will explore ways to overcome limitations in photosynthesis which could then lead to ways of significantly increasing the yield of important crops for food production or sustainable bioenergy. Despite the fact that photosynthesis is the basis of energy capture from the sun in plants, algae and other organisms, it has some fundamental limitations. There are trade-offs in nature which mean that photosynthesis is not as efficient as it could be – for many important crops such as wheat, barley, potatoes and sugar beet, the theoretical maximum is only 5%, depending on how it is measured. There is scope to improve it for processes useful to us, for example increasing the amount of food crop or energy biomass a plant can produce from the same amount of sunlight."

stinkymountain writes "With nearly $100 million in new funding, Internet2, the faster, better Internet reserved for research and education, has embarked on an upgrade that will boost backbone capacity to a staggering 8.8Tbps and expand services to hundreds of thousands of libraries, schools and medical centers. Internet2 was created by 34 university research institutions in 1996, when the commercial and non-commercial branches of the Internet's evolutionary tree split off and went their separate ways. The mission of Internet2 was to provide reliable, dedicated bandwidth to support the ever-growing demands of the research and educational communities, and in doing so, to develop technologies that would advance the state of the 'commodity' Internet. Some say it has failed in that latter category."

An anonymous reader writes "Storing passwords as hashes instead of plain text is now illegal in France, according to a draconian new data retention law. According to the BBC, '[t]he law obliges a range of e-commerce sites, video and music services and webmail providers to keep a host of data on customers. This includes users' full names, postal addresses, telephone numbers and passwords. The data must be handed over to the authorities if demanded.' If the law survives a pending legal challenge by Google, Ebay and others, it may well keep some major services out of the country entirely."
