Intel just released its new 48-core x86 processor on Dec, 2. Though not being the first to unveil a super multicore chip while Tilera already offers 32- and 64-core general-purpose processors (albeit non-x86) and previewed a 100-core version in October, Intel’s new processor is intended to totally research aims.
This new chip consists of 1.3 billion [...]
While the IPv4 addresses are being exhausted, the deployment of the new IPv6 infrastructure has been started, and you may have been enjoying the new technology now. The most improvement brought by IPv6 is the address space of 128 bit other than the 32 bit address in v4, making the number of available address extremely increased. However, at the same time, the use of IPv6 network, especially programming, is not completely compatible with the v4 case. This article discusses the domain name resolve problem and the programming implementation under IPv6 environment…
The Firefox version shipped with Fedora 10 is 3.0.x, so the newest version of Firefox that I’m able to update to is firefox.i386.3.0.13-1.fc10, although Firefox 3.5 has been released for a long time.
Of course, I can always manually install Firefox 3.5 by downloading the newest package, but this shall result in the existance of both [...]
Not long ago a “like” function came into the Google Reader and shows an annoying message “xx people liked this” under posts. It seems that Google did not provide any option to turn off this feature at first, but finally there comes one now!
When using the nslookup command in Windows to solve a domain name, a “Non-authoritative answer” message may be received and probably bringing much confusion. Many people states that “non-authoritative answer” means the answer comes from local DNS cache. However, this statement is not completely true. This article explains what exactly “non-authoritative answer” is.
It seems that the competition of the future web standards between HTML 5 and XHTML 2 has come to an end – just after the W3C (World Wide Web Consortium) announced that it is going to increase available resources to HTML 5 by DISCONTINUING further development of XHTML 2…
The quantum computer has been a dream of computer scientists for a long time. Based on the quantum theory, quantum computers may bring a fundamental to current computing models. However, research on quantum computers has been mainly focused on theoretical and laboratory experimental verification of the quantum model, but a solid-state realization has remained an outstanding challenge…
It has been a while that researchers have trying to make the mobile phones not to be just a communication tool but a smart device that can understand the holder’s behavior. Recently, researchers from Dartmouth College made a far step forward. They developed a tool that is able to determine the current “scene” by analyzing the sound picked up from the microphone of the mobile phone.
Google App Engine (GAE) is a cloud computing platform provided by Google. GAE allows users to create rich web applications using either Python or Java. Publicly released in Jul, 2008, there has been thousands of GAE applications online. The Google App Engine has been recently updated to version 1.2.3 with several new features along with, unfortunately, a major decrease of free quota.
The “quick launch” function on taskbar has been significantly improved in Windows 7. Popular programs can be “pinned” to the taskbar instead of being launched from an external “quick launch” bar. However, it is not easy to customize the appearance and function of the default “Windows Explorer” icon.
Ever since Windows Vista, Microsoft introduced a new /P switch for the famous FORMAT command. The /P switch zeros each bit in the volume a certain number of times. This function is very useful when you have sensitive data (such as privacy or classified content) on the disk.
The electricity consumption of large data centers has always been a critical problem. A large data center may run as much power as big city. The data center operators is trying hard to reduce the pwoer consumption of the servers. In a different way, researchers from Georgia Institute of Technology has recently developed a new [...]
Currently when accessing the Internet through wireless connections, such as using a netbook or cell phone, on a fast moving environment, the performance should be significantly limited. Recently researchers at Winlab, Rutgers University and NEC Laboratories have designed R2D2, a new system designed to fit this situation.
The fastest computer so far in Europe, JUGENE, was unveiled in Gauss Center at Forschungszentrum Jülich, Germany. JUGENE is also the first petaflop supercomputer in Europe, which can perform more than 1 trillion (1,000,000,000,000) mathematical operations per second…
I was currently working on an MFC dll and wanted to add some customization function to the model, which prompts a setting dialog. Unfortunately, the code failed to show the dialog…
Researchers from Swinburne University of Technology Just developed new disc technology, so called ‘five dimensional’ nanotechnology, bringing the storage capacity 2,000 times that of current DVDs…
A new report from Pablo de Olavide University and University of Seville, published in the magazine Technological Forecasting & Social Change, stating that the use of free software in South America and Asia will be around 70% in 2010, with a special relevance in the education sector. This number will be leading all around the world…
The Incognito mode of Google Chrome provides an excellent way to protect privacy (though not perfect yet) when browsing. However, starting the Incognito mode is a little tedious. Now it is easier to use a command line parameter to do this.
Tcl (Tool Command Language) is a very powerful but easy to learn dynamic programming language. Kathryn Edwards from Computerworld recently had an interview with Tcl creator John Ousterhout, about the most fascinate stuffs about Tcl, including the extensibility of Tcl, its diverse eco-system and use in NASA’s Mars Lander project.
Researchers from Penn State university have released ACQUINE (Aesthetic Quality Inference Engine), an online photo-rating search engine. According to the developers of the system, ACQUINE is the first publicly available tool for automatically determining the aesthetic value of an image…
