angry tapir writes "The creator of hypertext has criticized the design of the World Wide Web, saying that Tim Berners-Lee's creation is 'completely wrong,' and that Windows, Macintosh and Linux have 'exactly the same' approach to computing. Ted Nelson, founder of first hypertext project, Project Xanadu, went on to say, 'It is a strange, distorted, peculiar and difficult limited system... the browser is built around invisible links — you can see something to click on but you’ve got nowhere else to go.'"

An anonymous reader tips an account up at Wired of a hot new field of mathematics and applied algorithm research called "compressed sensing" that takes advantage of the mathematical concept of sparsity to recreate images or other datasets from noisy, incomplete inputs. "[The inventor of CS, Emmanuel] Candès can envision a long list of applications based on what he and his colleagues have accomplished. He sees, for example, a future in which the technique is used in more than MRI machines. Digital cameras, he explains, gather huge amounts of information and then compress the images. But compression, at least if CS is available, is a gigantic waste. If your camera is going to record a vast amount of data only to throw away 90 percent of it when you compress, why not just save battery power and memory and record 90 percent less data in the first place? ... The ability to gather meaningful data from tiny samples of information is also enticing to the military."

bughunter passes on a report from Wired Threat Level about the effort by Democratic lawmakers to roll back some provisions of the Patriot Act. Three of its provisions expire at the end of this year, and the reform attempt is expected to be attached to legislation to renew them. "Lawmakers are considering key changes to the Patriot Act and other spy laws — proposals that could give new life to lawsuits accusing the nation's telecommunications companies of turning over Americans' electronic communications to the government without warrants. On Oct. 1, the Senate Judiciary Committee likely will consider revoking that immunity legislation as it works to revise the Patriot Act and other spy laws with radical changes that provide for more government transparency and more privacy protections." Among the other likely goals of reform efforts, according to Wired, are limiting the government's power to issue National Security Letters, and limiting "black bag" searches to cases of spying or terrorism — 65% of past searches were authorized in drug cases.

t0mg writes with this news from the top of Slackware.org "from the Slackware64-current changelog: [tap tap tap]... Is this thing on? ;-) Ready or not, Slackware has now gone 64-bit with an official x86_64 port being maintained in-sync with the regular x86 -current branch. DVDs will be available for purchase from the Slackware store when Slackware 13.0 is released. Many thanks go out to the Slackware team for their help with this branch and a special thank you to Eric Hameleers who did the real heavy lifting re-compiling everything for this architecture, testing, re-testing, and staying in-sync with -current. We've been developing and testing Slackware64 for quite a while. Most of the team is already using Slackware64 on their personal machines, and things are working well enough that it is time to let the community check our work. We'd like to thank the unofficial 64 bit projects for taking up the slack for us for so long so that we could take our time getting everything just right. Without those alternatives, we would have been pressured to get things out before they were really ready."

A 14-year-old Wisconsin girl was arrested and charged with disorderly conduct after she refused to stop texting during a high school math class. The girl denied having a phone when confronted by a school safety officer, but a female cop found it after frisking her. The Samsung Cricket was recovered "from the buttocks area" of the teenager, according to the police report. The girl was banned from school property for a week, and is scheduled for an April 20 court appearance for a misdemeanor disorderly conduct charge. I applaud the adults involved for their discretion and temperance in this heinous case of texting without permission.

joe writes "Aram Harrow and colleagues have just published on the arXiv a quantum algorithm for solving systems of linear equations (paper, PDF). Until now, the only quantum algorithms of practical consequence have been Shor's algorithm for prime factoring, and Feynman-inspired quantum simulation algorithms. All other algorithms either solve problems with no known practical applications, or produce only a polynomial speedup versus classical algorithms. Harrow et. al.'s algorithm provides an exponential speedup over the best-known classical algorithms. Since solving linear equations is such a common task in computational science and engineering, this algorithm makes many more important problems that currently use thousands of hours of CPU time on supercomputers amenable to significant quantum speedup. Now we just need a large-scale quantum computer. Hurry up, guys!"

nk497 writes "Dr Paul Mockapetris is looking to fix the flaws in the Domain Name System he helped invent. 'It was never meant to be the only security mechanism for naming data on the internet, but was intended for additional security measures to be added to it later.' The flaws, first uncovered by security researcher Dan Kaminsky over the summer, lets attackers redirect genuine URLs to malicious ones — a problem Mockapetris believes could be solved using digital signatures."

An anonymous reader writes "In April, the Lonestar supercomputer, a Dell Linux Cluster with 5,840 processors at the Texas Advanced Computing Center in Austin, performed laser surgery on a dog in Houston without the intervention of a surgeon. The article describes the process: 'The treatment itself is broken into four stages: 1) Lonestar instructs the laser to heat the domain with a non-damaging calibration pulse; 2) the thermal MRI acquires baseline images of the heating and cooling of the patient's tissue for model calibration; 3) Lonestar inputs this patient-specific information and recomputes the optimal power profile for the rest of the treatments; and 4) surgery begins, with remote visualizations and evolving predictions continuing throughout the procedure.'"

While it may not be rocket science, the Twitter team has been making a concerted effort to effect better communication with their community at large. Recently they were set-upon by a barrage of technical and related questions and the resulting answers are actually somewhat interesting. "Before we share our answers, it's important to note one very big piece of information: We are currently taking a new approach to the way Twitter functions technically with the help of a recently enhanced staff of amazing systems engineers formerly of Google, IBM, and other high-profile technology companies added to our core team. Our answers below refer to how Twitter has worked historically--we know it is not correct and we're changing that."

An anonymous reader writes "A Singapore firm, VueStar has threatened to sue websites that use pictures or graphics to link to another page, claiming it owns the patent for a technology used by millions around the world. The company is also planning to take on giants like Microsoft and Google. It is a battle that could, at least in theory, upend the Internet. The firm has been sending out invoices to Singapore companies since last week asking them to pay up."

FreedomFighter writes "Since the release of Windows Vista, Creative has promised their Sound Cards as being 'Vista Ready'. Unfortunately, as many unlucky customers did discover, this is not true. What the users actually found were buggy, feature crippled drivers. Creative insisted that features such as Decoding of Dolby® Digital and DTS(TM) signals and DVD-Audio which worked fine in WinXP, would not work on windows Vista. With Creative releasing less than one new driver a year, things seemed bleak. Fortunately, a talented user, Daniel_K, was recently able to 'fix' many of the drivers, enabling the incompatible features and also fixing many bugs. Just today Creative has decided to put a stop to this. They removed all links to his modified drivers, and banned several users who were posting links to the now banned drivers."

tero writes "Even though Seagate has announced it will be offering SSD disks of its own in 2008, their CEO Bill Watkins seems to be sending out mixed signals in a recent Fortune interview 'He's convinced, he confides, that SSD makers like Samsung and Intel (INTC) are violating Seagate's patents. (An Intel spokeswoman says the company doesn't comment on speculation.) Seagate and Western Digital (WDC), two of the major hard drive makers, have patents that deal with many of the ways a storage device communicates with a computer, Watkins says. It stands to reason that sooner or later, Seagate will sue — particularly if it looks like SSDs could become a real threat.'"
