Malaysian Government Wants Internet Filtering
adewolf tips news that the government of Malaysia is looking into the development of an internet filtering program. According to a Reuters report, "A vibrant Internet culture has contributed to political challenges facing the government, which tightly controls mainstream media and has used sedition laws and imprisonment without trial to prosecute a blogger." The Malaysian government insists that such a filter would only be used to block pornography, though critics of the plan expect it would be wielded as a political tool, censoring websites that are critical of the current administration. "An industry source says the government could impose the filters late this year or in 2010, coinciding with the rollout of a high-speed broadband network run by Telekom Malaysia. Malaysia aims to increase broadband penetration to half of all homes by 2010 as part of its drive to boost economic efficiency."Read more of this story at Slashdot.
Garbage Collection Algorithms Coming For SSDs
MojoKid writes "A common concern with the current crop of Solid State Drives is the performance penalty associated with block-rewriting. Flash memory is comprised of cells that usually contain 4KB pages that are arranged in blocks of 512KB. When a cell is unused, data can be written to it relatively quickly. But if a cell already contains some data, even if it fills only a single page in the block, the entire block must be re-written. This means that whatever data is already present in the block must be read, then it must be combined or replaced, and the entire block is then re-written. This process takes much longer than simply writing data straight to an empty block. This isn't a concern on fresh, new SSDs, but over time, as files are written, moved, deleted, or replaced, many blocks are a left holding what is essentially orphaned or garbage data, and their long-term performance degrades because of it. To mitigate this problem, virtually all SSD manufacturers have incorporated, or soon will incorporate, garbage collection schemes into their SSD firmware which actively seek out and remove the garbage data. OCZ, in combination with Indilinx, is poised to release new firmware for their entire line-up of Vertex Series SSDs that performs active garbage collection while the drives are idle, in order to restore performance to like-new condition, even on a severely 'dirtied' drive."Read more of this story at Slashdot.
Ten Things We Still Don't Understand About Humans
ParticleGirl writes "New Scientist has an article examining 10 human features (bugs?) that we still don't understand, like blushing, laughing, and nose-picking. There are some interesting, speculative evolutionary explanations listed for each. '[Psychologist Robert R. Provine] thinks laughing began in our pre-human ancestors as a physiological response to tickling. Modern apes maintain the ancestral 'pant-pant' laugh when they are tickled during play, and this evolved into the human 'ha-ha.' Then, he argues, as our brains got bigger, laughter acquired a powerful social function — to bond people. Indeed, Robin Dunbar at the University of Oxford has found that laughing increases levels of endorphins, our body's natural opiates, which he believes helps to strengthen social relationships.'"Read more of this story at Slashdot.
Apple's Schiller Responds To iPhone Dictionary App Fiasco
beef curtains writes "Phil Schiller, Apple senior vice president of worldwide product marketing, responded by e-mail to a blog post discussing Apple's rejection of a dictionary app. If Schiller's e-mail is to be believed, it offers an interesting perspective on this whole issue. He said, 'The issue that the App Store reviewers did find with the Ninjawords application is that it provided access to other more vulgar terms than those found in traditional and common dictionaries, words that many reasonable people might find upsetting or objectionable. ... The Ninjawords developer then decided to filter some offensive terms in the Ninjawords application and resubmit it for approval for distribution in the App Store before parental controls were implemented. Apple did not ask the developer to censor any content in Ninjawords, the developer decided to do that themselves in order to get to market faster. ... You are correct that the Ninjawords application should not have needed to be censored while also receiving a 17+ rating, but that was a result of the developers' actions, not Apple's.' PC World has an article summarizing the drama-to-date, the blog post, and Schiller's response."Read more of this story at Slashdot.
WebGL Standard To Bring 3D Acceleration To Browsers?
Several sources are reporting that while native audio/video support has been dropped from the HTML 5 spec, the Khronos Group has released a few details about their up and coming WebGL 3D acceleration standard. "The general principle behind WebGL is to offer a JavaScript binding to the group's OpenGL ES 2.0 system, allowing code run within the browser to access the graphics hardware directly in the same way as a standalone application can. As the technology would rely solely on JavaScript to do the heavy lifting, no browser plugin would be required — and it would be compatible with any browser which supports the scripting language alongside the HTML 5 'Canvas' element."Read more of this story at Slashdot.
Nano Origami for DNA, Complete With Software
wisebabo writes "Some researchers at Technische Universitaet Muenchen and Harvard have developed a way to make DNA 'Origami' fold up into all sorts of desired nanoscale shapes. While this has been done before, there now seems to be a much greater assortment of shapes they can create. What's particularly interesting is that they've developed some software that can be used (presumably with a DNA assembler) that will create what you want; think of CAD/CAM on a molecular scale! 'The toolbox they have developed includes a graphical software program that helps to translate specific design concepts into the DNA programming required to realize them. Three-dimensional shapes are produced by "tuning" the number, arrangement, and lengths of helices.'"Read more of this story at Slashdot.
Microsoft Hardware Demos Pressure-Sensitive Keyboard
Krystalo writes to tell us that Microsoft hardware has an interesting demo of a pressure-sensitive keyboard they have designed. While there are no currently announced plans to turn this into a shipping product, there are many cool uses that one could imagine a device like this providing. "The device will be put to use in the first annual Student Innovation Contest in Victoria, Canada, where contestants will be supplied with a keyboard prototype and challenged with developing new interactions for it. Contestants will demo their creations and attendees will vote for their favorite at the conference on October 5. $2,000 prizes will be given to the authors of programs deemed as the most useful, the best implementation, and the most innovative."Read more of this story at Slashdot.
Murdoch Demands Kindle Users' Info
In yet another move to display how antiquated and completely ignorant of digital culture he is, Rupert Murdoch has started demanding that Amazon hand over user info for all Kindle users. This demand comes right after Murdoch just finished negotiating a larger share of revenue from Amazon sales. At least Amazon hasn't decided to comply with this request yet. "'As I've said before, the traditional business model has to change rapidly to ensure that our journalistic businesses can return to their old margins of profitability,' Murdoch said. 'Quality journalism is not cheap, and an industry that gives away its content is simply cannibalizing its ability to produce good reporting.'"Read more of this story at Slashdot.
LHC To Start Back Up In November At Half Power
mcgrew writes to mention that the Large Hadron Collider, smasher of particles, will get another chance to prove itself this November. The restart will begin with tests at half power, a mere 7 trillion electron volts (TeV), and ramp up slowly to the designed goal of 14 TeV. "Measurements indicate that some of the electrical connections could not safely handle the amount of current needed to run at the full 14 TeV, so will need to be replaced before dialing up the energy that far. But even 7 TeV is much higher than physicists have ever probed in the laboratory before. The Tevatron accelerator at Fermilab in Batavia, Illinois, is the current record holder, with collisions at 2 TeV."Read more of this story at Slashdot.
Ubuntu's New Firefox Is Watching You
sukotto writes "Ubuntu recently released an unannounced and experimental 'multisearch' extension to Firefox alpha 3, apparently in an effort to improve the default behavior of new tabs and of search. In a response to one of the initial bug reports the maintainers mentioned that the extension's other purposes were 'collecting the usage data' and 'generating revenue.' Since this extension installs by itself and offers no warning about potential privacy violations, quite a few people (myself included) feel pretty unhappy. The only way to opt out is to disable the extension manually via Tools > Add-ons." Most posters to this Ubuntu forum thread are not happy about multisearch.Read more of this story at Slashdot.
Bjarne Stroustrup On Concepts, C++0x
An anonymous reader writes "Danny Kalev has an interview with Bjarne Stroustrup about the failure of concepts, the technical issues of concepts, whether the ISO committee's days are over, and whether C++ is at a dead-end. 'I don't think that concepts were doomed to fail. Also, I don't think concepts were trying to fix many things or to transform C++ into an almost new language. They were introduced to do one thing: provide direct language support to the by-far dominant use of templates: generic programming. They were intended to allow direct expression of what people already state in comments, in design documents, and in documentation. Every well-designed template is written with a notion of what is required from its arguments. For good code, those requirements are documented (think of the standard's requirements tables). That is, today most templates are designed using an informal notion of concepts.'"Read more of this story at Slashdot.
Prehistoric Gene Reawakened To Battle HIV
Linuss points out research published in PLoS Biology that demonstrates the reawakening of latent human cells' ability to manufacture an HIV defense. A group of scientists led by Nitya Venkataraman began with the knowledge that Old World monkeys have a built-in immunity to HIV: a protein that can prevent HIV from entering cell walls and starting an infection. They examined the human genome for any evidence of a latent gene that could manufacture such a protein, and found the capability in a stretch of what has been dismissively termed "junk DNA." "In this work, we reveal that, upon correction of the premature termination codon in theta-defensin pseudogenes, human myeloid cells produce cyclic, antiviral peptides (which we have termed 'retrocyclins'), indicating that the cells retain the intact machinery to make cyclic peptides. Furthermore, we exploited the ability of aminoglycoside antibiotics to read-through the premature termination codon within retrocyclin transcripts to produce functional peptides that are active against HIV-1. Given that the endogenous production of retrocyclins could also be restored in human cervicovaginal tissues, we propose that aminoglycoside-based topical microbicides might be useful in preventing sexual transmission of HIV-1."Read more of this story at Slashdot.
Microsoft Denies Windows 7 "Showstopper Bug"
Barence writes "Windows chief Steven Sinofsky has taken the unusual step of responding in the comments of a blog posting that claimed Windows 7 was suffering from a potential 'showstopper bug'. Stories had been sweeping the Internet that using the chkdsk.exe utility on a second hard disk would lead to a massive memory leak bringing the operating system to its knees in seconds. Responding to a blog post titled 'Critical Bug in Windows 7 RTM,' Sinofsky wrote: 'While we appreciate the drama of "critical bug" and then the pickup of "showstopper" that I've seen, we might take a step back and realize that this might not have that defcon level.' He signs off with the words: 'deep breath.'"Read more of this story at Slashdot.
Underground App Store Courts the Jailbroken
PainMeds writes "Apple's stepped-up and controversial rejections are helping to foster competition in the app store marketplace. According to an article by Wired, developers aren't taking AppStore rejection lying down, but are turning to the hacking community's repository system for the iPhone to launch an app store of their own. The 4-month-old Cydia store is yielding notably higher sales for a few application developers than Apple's AppStore, and is reportedly running on over 4 million Apple iPhone devices, with perhaps 350,000 connected at any one time. In this store, developers are distributing applications they've written that push the limits of Apple's normal AppStore policies, with software to add file downloads to Safari, trick applications into thinking they're on Wi-Fi (for VoIP), and enhance other types functionality. You'll also find the popular Google Voice application, which was recently rejected by Apple. Third party application development has been around since 2007, when the iPhone was originally introduced, and became so popular that O'Reilly Media published a book geared toward writing applications before an SDK was available. The Cydia store acts as both a free package repository and commercial storefront to third-party developers."Read more of this story at Slashdot.
Twitter, Facebook DDoS Attack Targeted One User
An anonymous reader writes "A Georgian blogger with accounts on Twitter, Facebook, LiveJournal, and Google's Blogger and YouTube was targeted in a denial of service attack that led to yesterday's site-wide outage at Twitter and problems at the other sites on, according to a Facebook executive. The blogger, who uses the account name 'Cyxymu' (the name of a town in the Republic of Georgia), had accounts on all of the different sites that were attacked at the same time, Max Kelly, chief security officer at Facebook, told CNet News." Here are user Cyxymu's LiveJournal Google cache and LiveJournal account (unreachable at this writing). Larry Magid writes on CNet that this individual blogs about independence of a breakaway region of Georgia. Macworld has some speculation in other directions on the motivations behind the DDoS attack. Update: 08/07 19:52 GMT by KD : Cyber attacks on Cyxymu are not new. For over a year Evgeny Morozov has been calling attention to him as the first digital refugee.Read more of this story at Slashdot.
