Submission + - Facebook Awarded Patent for its News Feed

adeelarshad82 writes: Facebook has secured a patent to a feature that many of its competitors have adopted in recent years, the news feed. The patent, officially granted on Tuesday by the U.S. Patent and Trademark Office, governs a "method for displaying a news feed in a social network environment." Facebook applied for the patent back in August 2006, about a month before the social networking site opened its doors beyond college students to all Internet users.

Submission + - The New Rules of Facebook (mainstreet.com)

rexjoec writes: Sometimes new technologies pop up before we really establish guidelines for how to use them. It happened with e-mail and instant messages, and now it has happened with Facebook as well.

Who should you be friends with on Facebook? What content should you feel comfortable putting up? Without clear rules of conduct, people have made some pretty dumb mistakes. In the past, people have been fired from jobs and even evicted from their homes because they posted questionable pictures or status updates on the social network

Earlier this week, Liberty Mutual released the results of their survey about what constitutes proper Facebook conduct. Some of the results are surprising.

Submission + - Exploring Advanced Format Hard Drive Technology (hothardware.com) 1

MojoKid writes: Hard drive capacities are sometimes broken down by the number of platters and the size of each. The first 1TB drives, for example, used five 200GB platters; current-generation 1TB drives use two 500GB platters. These values, however, only refer to the accessible storage capacity, not the total size of the platter itself. Invisible to the end-user, additional capacity is used to store positional information and for ECC. The latest Advanced Format hard drive technology changes a hard drive's sector size from 512 bytes to 4096K. This allows the ECC data to be stored more efficiently. Advanced Format drives emulate a 512 byte sector size, to keep backwards compatibility intact, by mapping eight logical 512 byte sectors to a single physical sector. Unfortunately, this creates a problem for Windows XP users. The good news is, Western Digital has already solved the problem and this quick overview at HotHardware offers some insight into the technology and how it performs.

Submission + - Has Facebook patented the news feed? (yahoo.com)

bth writes: Has Facebook patented the news, or at least the news feed, in social-networking environments? On Tuesday, the United States Patent Office granted Facebook a patent for "Dynamically providing a news feed about a user of a social network." The patent is published and numbered 7,669,123.

The first claim is: A method for displaying a news feed in a social network environment, the method comprising: monitoring a plurality of activities in a social network environment; storing the plurality of activities in a database; generating a plurality of news items regarding one or more of the activities, wherein one or more of the news items is for presentation to one or more viewing users and relates to an activity that was performed by another user; attaching a link associated with at least one of the activities of another user to at least one of the plurality of news items where the link enables a viewing user to participate in the same activity as the another user; limiting access to the plurality of news items to a set of viewing users; and displaying a news feed comprising two or more of the plurality of news items to at least one viewing user of the predetermined set of viewing users.

LaserMotive Finds Success In Space Elevator Competition 258

Bucc5062 writes "LaserMotive has achieved the first step towards the creation of a working space elevator by qualifying for the $900,000 prize in a contest sponsored by NASA. To achieve this first level, LaserMotive needed to propel a platform up a cable dangling from a helicopter at over 2 m/s. They hit a top speed of 4.13 m/s. The next level of qualification will be to achieve a climb speed greater then 5 m/s. LaserMotive beamed roughly 400 watts of laser power to a moving target at a distance of 1 kilometer, as part of the vertical laser alignment procedure. The target was a retro-reflective board a little larger than 1 meter on a side. The contest will continue for another two days with at least two other teams challenging for the prize. To win the Power Beaming competition, the LaserMotive system uses a high-power laser array to shine ultra-intense infrared light onto high-efficiency solar cells, converting the light into electric power which then drives a motor. 'Our system will track the vehicle as it climbs, compensating for motion due to wind and other changes. Building on our experience from last year’s competition, we are designing an improved system able to capture the full $2,000,000 prize.'"

Sony Demo'ing 360 Degree 3-D Tabletop Display 102

JoshuaInNippon writes "Sony announced via a Japanese press release that they will be showing off a prototype of a tabletop 360 degree 3-D display that can be seen in any direction without special glasses at the Digital Content Expo 2009 in Tokyo, from October 22-25. The device is quite small, at just over 10 inches tall and 5 inches in diameter. The display, using LEDs, currently supports an image that is 96 pixels wide by 128 pixels tall, with 24-bit full color. Sony also says it could have a number of applications, such as a digital sign, a digital frame, a medical display, or a virtual pet. Looking at the product image, who else wants to bet on the latter?)"

Comment But what about netloc absolutes? (Score 1) 620

Okay, so noone uses them, but TBL's own RFC in section C.1 demonstrates the use of an initial double-forward-slash meaning change the netloc without changing the protocol. This could be useful if you're dealing with resources that have the same mapping on multiple protocols (like http and https). I know it's a corner case, but it is still technically a documented use case...

The LHC, the Higgs Boson, and Fate 691

Reader Maximum Prophet sends a piece from the NY Times by the usually reliable Dennis Overbye reporting on a "crazy" theory being worked up by a pair of "otherwise distinguished physicists": that the Large Hadron Collider's difficulties may be due to the universe's reluctance to produce a Higgs boson. Maximum Prophet adds, "This happened to the Superconducting Super Collider in the science fiction story Einstein's Bridge. Now Holger Bech Nielsen, of the Niels Bohr Institute in Copenhagen, and Masao Ninomiya of the Yukawa Institute for Theoretical Physics in Kyoto, Japan, are theorizing that it's happening in real life." "I'm talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather."

Submission + - How to monitor a MySQL server in real time?

oliderid writes: I have almost finished a web application that should support more than 100 queries per second some tables having more than 500.000 rows. Well I'm not used to this kind of load. I did my best to apply the best practices I could find over the web, reduce the queries to the database to the minimum, indexing, etc. but I'd like to have a GPL tool to monitor this database in real-time and see clearly how often a query is done, redundant ones, be sure that my mental is respected "One query per "page", processing time, etc. See when the server is about to be overloaded. The server is remote, Linux (redhat or ubuntu). There is no Xwindow, so I can monitor it through SSH/shell or through a web application. Any idea? Thx!

Image Recognition Neural Networks, Open Sourced 98

sevarac writes "The latest release of Java Neural Network Framework Neuroph v2.3 comes with ready-to-use image recognition support. It provides GUI tool for training multi layer perceptrons for image recognition, and an easy-to-use API to deploy these neural networks in end-user applications. This image recognition approach has been successfully used by DotA AutoScript tool, and now it is released as open source. With this Java library basic image recognition can be performed in just few lines of code. The developers have published a howto article and an online demo which can be used to train image recognition neural networks online."
