I've met some nontechnical (not at all CS, use Windows, though use computers for a living) 20- and 30-somethings in China -- they all know how to get around the Great Firewall, or at least know somebody who knows how to get around it. It's not something they worry much about, as long as they aren't generating politically sensitive content themselves. I haven't met any of the latter people.

Your Computer and Cell Phone Are Lying To You 479

Posted by timothy on Tuesday July 29, 2008 @10:00AM from the they're-in-it-with-the-aliens dept.

Ant writes with a story from Dan's Data, which says that the battery meter and connection-strength displays in your portable electronics are lying to you, "and not just when they whisper to you in the night." Quoting: "Mobile phones, and most modern laptops, have signal strength and battery life displays. One or both of these displays has probably been the focus of all of your attention at one time or another. Neither display is actually telling you what you think it's telling you. The signal strength bars on a mobile phone or laptop do, at least, say something about how strong the local signal is. But they don't tell you the ratio between that signal and the inevitable, and often very considerable, noise that accompanies it ..."

Claimed Proof of Riemann Hypothesis 345

An anonymous reader writes "Xian-Jin Li claims to have proven the Riemann hypothesis in this preprint on the arXiv." We've mentioned recent advances in the search for a proof but if true, I'm told this is important stuff. Me, I use math to write dirty words on my calculator.

Are SSDs Really More Power Efficient? 222

Posted by CmdrTaco on Wednesday July 02, 2008 @10:12AM from the how-will-i-green-up-now dept.

Bakasama writes "Tom's Hardware compared the power performance of several available SSD cards with a Rotating HDD that was chosen specifically for its poor power efficiency. The results seem to fly in the face of current wisdom. 'Flash-based solid state drives (SSDs) are considered to be the future of performance hard drives, and everyone seems to be jumping on the bandwagon. We are no exception, as we have been publishing many articles on flash-based SSDs during the last few months, emphasizing the performance gains and the potential power savings brought by flash memory. And there is nothing wrong with this, since SLC flash SSDs easily outperform conventional hard drives today (SLC = single level cell). However, we have discovered that the power savings aren't there: in fact, battery runtimes actually decrease if you use a flash SSD.'"

Supplies of Rare Earth Elements Exhausted By 2017 958

Posted by kdawson on Wednesday July 02, 2008 @08:11AM from the they-don't-call-them-rare-for-nothing dept.

tomhudson writes "While we bemoan the current oil crisis, I ran across an editorial that led me to research a more immediate threat. Ramped-up production of flat-panel displays means the material to make them will be 'extinct' by 2017. This goes for other electronics as well. Quoting: 'The element gallium is in very short supply and the world may well run out of it in just a few years. Indium is threatened too, says Armin Reller, a materials chemist at Germany's University of Augsburg. He estimates that our planet's stock of indium will last no more than another decade. All the hafnium will be gone by 2017 also, and another twenty years will see the extinction of zinc. Even copper is an endangered item, since worldwide demand for it is likely to exceed available supplies by the end of the present century.' More links at the journal entry."

The Scream Aliens Hear From the Earth 223

onehitwonder writes "Astronomers have discovered that the Earth emits awful, ear-piercing chirps and whistles that could be heard by any aliens who might be listening, according to an article up at Space.com. The sounds are created by charged particles from the solar wind colliding with Earth's magnetic field. This article explains more about the sounds and links to an audio recording of it."

Helping Some Students May Harm High Achievers 1114

Posted by samzenpus on Thursday June 19, 2008 @05:20AM from the stop-dragging-us-down dept.

palegray.net writes "According to a new study performed by the Thomas B. Fordham Institute in Washington, increased emphasis on helping students with a history of lower academic achievement results in lower performance for high achievers. This trend appears to be related to the No Child Left Behind Act. Essentially, programs designed to devote a large number of resources to assisting students who are deemed to be 'significantly behind' leave little room for encouraging continued academic growth for higher-performing students."

Man Fired When Laptop Malware Downloaded Porn 635

Posted by samzenpus on Wednesday June 18, 2008 @06:59PM from the your-computer-wants-porn dept.

Geoffrey.landis writes "The Massachusetts Department of Industrial Accidents fired worker Michael Fiola and initiated procedures to prosecute him for child pornography when they determined that internet temporary files on his laptop computer contained child porn. According to Fiola, 'My boss called me into his office at 9 a.m. The director of the Department of Industrial Accidents, my immediate supervisor, and the personnel director were there. They handed me a letter and said, "You are being fired for a violation of the computer usage policy. You have pornography on your computer. You're fired. Clean out your desk. Let's go."' Fiola said, 'They wouldn't talk to me. They said, "We've been advised by our attorney not to talk to you."' However, prosecutors dropped the case when a state investigation of his computer determined there was insufficient evidence to prove he had downloaded the files. Computer forensic analyst Tami Loehrs, who spent a month dissecting the computer for the defense, explained in a 30-page report that the laptop was running corrupted virus-protection software, and Fiola was hit by spammers and crackers bombarding its memory with images of incest and pre-teen porn not visible to the naked eye. The virus protection and software update functions on the laptop had been disabled, and apparently the laptop was 'crippled' by malware. According to Loehrs, 'When they gave him this laptop, it had belonged to another user, and they changed the user name for him, but forgot to change the SMS user name, so SMS was trying to connect to a user that no longer existed ... It was set up to do all of its security updates via the server, and none of that was happening because he was out in the field.' A malware script on the machine surfed foreign sites at a rate of up to 40 per minute whenever the machine was within range of a wireless site."

China Launches Antitrust Probe Vs. Microsoft 295

Posted by CmdrTaco on Wednesday June 18, 2008 @11:21AM from the get-on-the-bus dept.

snydeq writes "China has launched an investigation into whether Microsoft unfairly dominates its software market, according to a state media report. A working committee of China's State Intellectual Property Office is investigating whether Microsoft engaged in discriminatory pricing and will also look at Microsoft's practice of bundling other software programs within its Windows operating system, according to the report. The probe is part of a greater sweep of operating systems and other software developed by multinational companies that cost much more in China than in the U.S. 'On the one hand, global software firms, taking advantage of their monopoly position, set unreasonably high prices for genuine software while on the other hand, they criticise Chinese for poor copyright awareness. This is abnormal,' a source said."

Wikileaks Gets Hold of Counterinsurgency Manual 999

Posted by kdawson on Wednesday June 18, 2008 @08:06AM from the what-we-learned-in-central-america dept.

HeavensBlade23 writes in to let us know that Wikileaks has published a US Special Forces counterinsurgency manual, titled Foreign Internal Defense Tactics Techniques and Procedures for Special Forces (1994, 2004). "The document, which has been verified, is official US Special Forces doctrine. It directly advocates training paramilitaries, pervasive surveillance, censorship, press control and restrictions on labor unions & political parties. It directly advocates warrantless searches, detainment without charge and the suspension of habeas corpus. It directly advocates bribery, employing terrorists, false flag operations and concealing human rights abuses from journalists. And it directly advocates the extensive use of 'psychological operations' (propaganda) to make these and other 'population & resource control' measures more palatable."

Replacement For Aging Doppler Radar Being Tested 105

Posted by kdawson on Wednesday June 18, 2008 @05:12AM from the sounds-like-a-freight-train dept.

longacre writes "Due to its limited range and slow scan times, the backbone of weather prediction in the US since the early 1990s, the NEXRAD radar system, is deeply flawed in the eyes of meteorologists. A new system being tested by researchers at the NOAA and four universities called the Collaborative Adaptive Sensing of the Atmosphere (CASA) network aims to fill the holes left by NEXRAD, using radar nodes piggybacked onto existing infrastructure, such as rooftops and cell towers. From the article: 'Based on faster and more comprehensive data collection, [Distributed Collaborative Adaptive Sensing] processing can refocus the CASA radars on a particularly interesting part of a storm (like an area that looks like it might develop a tornado) without losing track of an entire storm cell. "The system is continuously diagnosing the atmosphere and reallocating resources using wireless Internet as a backbone," says [the CASA team director].' Testing has begun in Oklahoma, Houston, and Puerto Rico, and initial installations could begin in 5 years."

All Your Coffee Are Belong To Us 354

Wolf nipple chips writes "Craig Wright discovered that the Jura F90 Coffee maker, with its honest-to-God Jura Internet Connection Kit, can be taken over by a remote attacker, who can cause the coffee to be weaker or stronger; change the amount of water per cup; or cause the machine to require service (call this one a DDoC). 'Best yet, the software allows a remote attacker to gain access to the Windows XP system it is running on at the level of the user.' An Internet-enabled, remote-controlled coffee-machine and XP backdoor — what more could a hacker ask for?"

Even Before Memex, a Plan For a Networked World 119

Posted by timothy on Tuesday June 17, 2008 @09:05AM from the da-vinci-invented-everything dept.

phlurg writes "The New York Times presents an amazing article on 'the Mundaneum,' a sort of proto-WWW conceived of by Paul Otlet in 1934. 'In 1934, Otlet sketched out plans for a global network of computers (or "electric telescopes," as he called them) that would allow people to search and browse through millions of interlinked documents, images, audio and video files. He described how people would use the devices to send messages to one another, share files and even congregate in online social networks. He called the whole thing a "réseau," which might be translated as "network" — or arguably, "web."' A fascinating read." (You may be reminded of Vannevar Bush's "Memex," which shares some of the same ideas.)

Google To Develop ISP Throttling Detector 198

bigwophh writes "Google has been very vocal on its stance for net neutrality. Now, Richard Whitt — Senior Policy Director for Google — announces that Google will take an even more active role in the debate by arming consumers with the tools to determine first-hand if their broadband connections are being monkeyed with by their ISPs."
