The most interesting fact about this project is that it was designed by high school students. It even includes lux measurements at various angles to compare their lamp to fluorescent lamps. They also provide instructions on how to build your own lamp just like they did."

There has been no firmware update for the ADP1, but one is supposedly in the works. In all likelihood, all that's needed to access paid apps is an updated Android Market application. The holiday bonus firmware quite probably has an updated market app, and thus works.

If that's true, this article is completely alarmist. I won't believe the ADP1 can't access paid apps until I hear it from Google itself.

Disguising traffic is quite easy to do in many cases. For example, many Bittorrent clients support the notion of "HTTP seeding". This uses the protocol traditionally associated with the web for bulk file transfer. This bittorrent traffic does not have the same requirements as your web browsing, despite using the same protocol!

You're right that you might want both low latency and high bandwidth. In that case, you would (as you said) have to pay a premium for it. No matter what price point you choose, though, you probably still want to make a distinction between bittorrent and VOIP. Their requirements are worlds apart.

So my point is that even if the ISP can determine the protocol, that doesn't necessarily correspond to what the applications communicating need. Moreover, if it's encrypted traffic, the ISP likely can't even determine the protocol. So having the application on the customer's computer tag the traffic with its requirements is the only way you can get even close to optimal (and neutral) traffic shaping.

Submitted by Jordan (jman)
Jordan (jman) (212384) writes "I have been looking into setting up an email server for a small buisiness. It won't be anything very complicated. It will have one domain and a few dozen users, but may need more domains and users in the future. I want to set it up with POP, IMAP, and webmail access. The configuration of mail servers does not seem to be a simple task by any means. I started looking for an easier way than reading up for a couple weeks. I would like to find something with the simplicity and web based configuration like in the hosting control panels. Control panels like cPanel, Plesk, etc make it easy but I do not need all the other features such as webserver, DNS, FTP, and so on. Also, something free would always be nice. Are there any control panels out there for email alone?"

He discusses OTR and its importance in today's world with warrant-less wire tapping and all that bad stuff. With OTR users benefit from being able to have truly private conversations over IM, by using encryption to obtain authentication, deniability, and perfect forward secrecy, while working within their existing IM infrastructure. With the recent NSA wiretapping activities and increasing Big Brother presence, security and OTR are increasingly important. An avi of the talk is available by http as well as by bittorrent and a bunch of other formats."

Stony Stevenson (954022) writes "Researchers at Virginia Tech have released the first Green 500 list which ranks the world's supercomputers by performance-per-watt rather than pure processing power. The list of the 500 most energy efficient supercomputers around the world is a derivative of the Top 500 list, a bi-annual report of the top performing supercomputer sites. This inaugural list uses the measured power consumed during a Linpack run, if submitted, or peak power consumption of the supercomputer otherwise. The top of the list is completely dominated by IBM's Blue Gene supercomputers, with 26 of the top 27 deployments."

Roland Piquepaille writes "New Zealand computer scientists have developed Eve, an affective tutoring system (ATS) which can adapt its response to the emotional state of children by interaction through a computer system. The researchers say their teaching system, dubbed 'Easy with Eve,' is the first of its type and add they 'wanted to create a virtual teacher capable of reading and understanding body language and facial expressions to ensure that it has the attention of students.' Today, Eve teaches mathematics, but this 'robotic' intelligent system could be adapted to other situations and become an important development in the $25 billion e-learning market. But read more additional references and for for pictures of Eve in action."

+ - Microsoft partner to derail Russian state Linux?

Submitted by
An anonymous reader writes "Russian government has recently announced a contest of proposals to develop a "set of Open source software for educational use", or in plain words, create a state-supported distribution of OS and educational software for schools and universities.

Maximum bid price for this project is fixed by the government to be about $2.8 mln. Five known companies and one university have replied with proposals to develop the software, and named prices from about $1.6 mln. to $2.8 mln.

However, the really interesting is the seventh proposal. It names a dumping price of just $200k for whole project. The proposing company, "KORUS Consulting", in a statement on their website says that in reality the project is going to cost them about $2.6 mln., but since they have decided to "invest heavily" in "Russian OSS market", they... will pay the remaining $2.4 mln. of these expenses out of their own pockets.

What makes this very creepy, is another page of KORUS website, describing the company as having "the highest status of partnership with Microsoft — a Gold Certified Partner, and a Certified Education Partner, and also that in 2006 the company was a part of Microsoft's Presidential Club, which only "top" 5% of Microsoft partners are allowed to join."

So, could it be, that this company (and Microsoft through it) looks to make the Russian Linux project a failure, by first winning it with offer which is ten times cheaper than everyone else's, then gathering all the rights to execute the state projects in this area, and then.. not producing anything even remotely usable, pushing all the potential users of this project's product back into the shackles of Windows and MS Office?

The project is currently in the proposals evaluation stage. Surely, will be interesting, how that turns out."

Peak oil is the point in time where smaller new discoveries are unable to offset declining production from older fields and we'll have to make due with ever declining oil production. Since 1980 we have been consuming more oil then we discover each year. Also, world oil production peaked at 85.5 million barrels per day in July 2006 and despite strong demand hasn't come close to this mark since."

He also notes that some implementations, such as Trillian, are vulnerable to man-in-the-middle attacks. Goldberg then explains how OTR is able to overcome these deficiencies, and provide deniability and perfect forward secrecy.

Mike writes "In a recent talk, C++ creator Bjarne Stroustrup described the goals he and the ISO C++ Committee have for the next version of the C++ standard. The new standard, tentatively 'C++0x', aims to make programs easier to write and maintain without sacrificing efficiency. Unfortunately, the challenges of revising an existing language and the rigor required make the standardization process slow and painful. The number of proposed features for C++0x far exceeds the number that can feasibly be standardized. Stroustrup describes two new features he believes will make the language much more expressive: initializer lists and concepts. The talk is available for download."
