Submission + - Nanoresonators create ultra-high-res displays (

TuurlijkNiet writes: Eat your heart out, 'Retina display'. A new technology unveiled yesterday will allow creating pixels eight times smaller than the ones on Apple's iPhone 4, eliminate the need for polarizer layers, and allow screens to make much more efficient use of available light, say University of Michigan researchers. The pixels in the nanoresonator displays are about ten times smaller than those on a typical computer screen, and about eight times smaller than the pixels on the iPhone 4, which are about 78 microns, according to Guo. Such pixel densities could make the technology useful in projection displays, as well as wearable, bendable or extremely compact displays, according to the researchers.

Submission + - Why Contributor Agreements Are Community-Toxic (

WebMink writes: "A project dubbed "Harmony", imitated by Canonical, is trying to get so-called "contributor agreements" standardised to save corporations money. But the process could also standardise on copyright aggregation, where community participants donate their work to corporate sponsors. Many big open source communities — including Linux, Apache, GNOME and Mozilla — avoid doing so and have large communities as a consequence. This comprehensive article explores the reasons corporations want copyright aggregation and the reason it's toxic to open source communities."

Submission + - TextMaker 2010 more ODF compliant than OpenOffice? (

An anonymous reader writes: SoftMaker Office ( ) runs on Windows, Windows CE and Linux. the 2010 version brings ODF Import/Export capabilities. Even if this support is relatively new, it seems that SoftMaker Office 2010 (TextMaker) is more ODF compliant than OpenOffice Writer 3.2.1 ( )
The tests were done using toture test files from another competitor (ThinkFree Office, that lacks of ODF capability) and the story can be found here :

For validation, I used the official ODF validator :

Even if both product were not perfect, only TextMaker gave me a valid ODF file (from a simple document, though)

More tests are to follow but it is quite astounding that OpenOffice is not 100% compliant yet...


Submission + - China Unveils Plans to Mine the Yellow Sea Floor (

eldavojohn writes: Details are limited but state media is reporting on $75 million being put into a new research facility in Qingdao, Shandong Province that will conduct research into mining the sea floor. From the article, 'Scientists believe sea beds at a depth of 4,000 to 6,000 meters hold abundant deposits of rare metals and methane hydrate, a solidified form of natural gas bound into ice that can serve as a new energy source.' The research center's first goal is to do surveying and exploration with a new submersible named "Jiaolong" (a mythical aquatic Chinese dragon). Hopefully these quests yield energy resources to curb growing demand for resources like liquefied coal in China.

Submission + - New Data Implies 'Fine Structure Constant' Changes (

eldavojohn writes: Two papers in prepublication claim that the fine structure constant has changed (probably over time). It's long been theorized that as the universe ages constants we have now change ever so slightly over time and the only way to test this theory is to point very sensitive equipment at light that passed through gas clouds millions of light years away. The real conundrum comes from the measurements that researchers have collected from the Keck Telescope in 2004 and the Very Large Telescope today. The Keck data, which was harvested from the Northern Hemisphere, indicates that the fine structure constant was once smaller while the VLT data, which was harvest from the Southern Hemisphere, indicates that the fine structure constant was once LARGER. This causes the research to indicate a spatial dependence on variances in the fine structure constant with suggestions that changes in the fundamental constants may be observable as 'spatial anisotropy in the cosmic microwave background, the accelerated expansion (dark energy), and large-scale structure of the Universe.' Of course, challenging constants is all the rage these days.

Submission + - Ask Slashdot: Best video surveillance system 1

An anonymous reader writes: I need an inexpensive video surveillance system (about four fixed cameras and one PTZ) which i can control it through the Internet. It must work for a distance of over 30 m (100ft) both day and night and it must be compatible with a Linux server. What do you recommend me to use?

Submission + - Micro-volunteering through mobile phones (

An anonymous reader writes: I want to talk to you about a new app from a 26 year old young man called Jacob Colker. I work with Rolex and they have recently selected Jacob as a Rolex Young Laureate and awarded him with $50,000 in recognition of the amazing success this app has had in terms of turning everyday mobile phone users into individuals who offer their spare time to many valuable causes — simply because the app enables micro-volunteering by matching the users specific skill or expertise to a number of charities and organisations who seek assistance and help via volunteering programmes.
Tapping into the latest trends in information and telecommunications technology, Jacob Colker has combined volunteering, the internet and mobile phones to pioneer a new form of activism in which almost anyone with a smartphone can devote spare minutes – waiting for the bus or to see the doctor – to a useful charitable or scientific task.
Over 40,000 volunteers have now signed up for “micro-volunteering," carrying out a wide range of tasks, from helping NASA identify galaxies by examining their shapes to translating the CVs of newly arrived immigrants who are looking for work. Colker will use his Rolex Award to expand micro-volunteering to more internet uses and gain publicity to “encourage millions of people to volunteer.

Submission + - Machine Learning For Detection of Anomalous SIP

sylverboss writes: SIP DDoS attacks are becoming more widespread than ever (specially the ones originating from China) which can trigger 100's of SIP messages per sec and a large volume of traffic. Snort and IPTABLES are good tools to alert and mitigate such attacks but become limited when new attacks are launched. By the time the attack is stopped, the damage is done. In this paper, Konrad R. (who I've contacted) and others describe a "A Self-Learning System for Detection of Anomalous SIP Messages". Their approach is interesting but unfortunately the software has been developed for Alcatel/Lucent. So, I wonder if the Slashdot community has implemented efficient ways to mitigate "0-day" type of attacks or even better detect anomalies in SIP signaling by just using open source software or very clever iptables rules.

Submission + - iPad tactile object recognition system (

An anonymous reader writes: The guys over at the Volumique blog have a different idea as to how to tackle apps for Apple’s devices. They aren’t just thinking about a digital activity on such devices, they are experimenting with using physical objects through Apple’s multi-touch screens.

Imagine being able to buy the playing pieces for a board game, but then loading up an app on your iPad for the actual board. The pieces would be recognized when placed on the iPad’s screen, it would even recognize which direction they were facing. This may sound like an impossible feat unless you use a much more expensive device like Microsoft Surface, but Bertrand Duplat and Etienne Mineur at Volumique already have it working.


Submission + - The Most Dangerous Countries Online? (hokum!) (

An anonymous reader writes: AVG reckons it has uncovered the most dangerous countries (and the safest) online from the perspective of using the Internet. Nice bit of research lads, but what a bunch of hokum. It's not where you are that matters, but what you do and how you do it. A link clicking moron is dangerous wherever he is. Doh!

Submission + - Casing Pictures Point To New iPod Nano Format (

siliconbits writes: Rumours have emerged about a new completely design for Apple's smallest iPod member, the Nano, a move that could reaffirm Apple's intention to keep the classic iPod audio players alive and kicking despite growing internal competition from the iPod Touch and the iPhone.
GNU is Not Unix

Glibc Is Finally Free Software 337

WebMink writes "Despite the fervour of some, the dark secret of every GNU/Linux distribution is that, until August 18 this year, it depended on software that was under a non-Free license — incompatible with the Open Source Definition and non-Free according to Debian and the FSF. A long tale of tenacity and software archeology has finally led to that software appearing under the 3-clause BSD license — ironically, at the behest of an Oracle VP. The result is that glibc, portmap and NFS are no longer tainted."
