Recently writes of Facebook started to switching from PHP to C++, Facebook could move from 30,000 servers down to just 7,500 servers, and trim 49,000 tons of carbon dioxide emissions from its footprint.
We do not yet know what do these 30000 servers mean in terms of CO2? And what would be the impact of a more sane language instead of PHP?
Since an average server consumes about 200 Watt, and with an average SI EER (Site Infrastructure Energy Efficiency Ratio) of 2 this translates to around 400 Watt including cooling and other overhead. In the USA, an average of 560 grams CO2 is emitted per generated Killo Watt hour, and this brings us to a total CO2 emission by the Facebook server park of about 59 000 ton of CO2 per year…As they only say that “the bulk” is running PHP… let’s assume this to be 25 000 of the 30 000… If C++ would have been used instead of PHP, then 22 500 servers could be powered down (assuming a conservative ratio of 10 for the efficiency of C++ versus PHP code), or a reduction of 49 000 ton.
MATH is a stack orientated esoterical programming language based on the small multiplication table. It features three different programming difficulties, String output, basic integer calculations, condionional und unconditional jumps + sub programs.

Google’s Android operating system is rapidly gaining mindshare among smartphone users.
It’s true, that great news for Google, which is preparing to deliver the Google-branded Nexus One early in the new year and stake a permanent position as a smartphone powerhouse.
In an August report, when Android phones had yet to erupt and only the T-Mobile G1 and T-Mobile MyTouch were widely available, Comscore reported 7 percent of users who planned to buy an Android-based smartphone in the next three months, and 21 percent of users planning to buy an iPhone.

Recently Avatar is released which is some thing more than 3d its digital-3d technology.
Wherever visual media is delivered, RealD has a solution to make the experience more lifelike, immersive and engaging.
How does it work?
Human both eyes makes slightly different images and our brain combines them in a single image. Now this different views of eyes allows brain to determine the depth and distance of image. In avatar this concept is used. this 3d technology is introduced in Movie marker is like color films introduced in black-white move market. RealD pioneered the first wide commercial deployment of stereoscopic projection systems for digital cinema and works with partners worldwide to create the most powerful 3D experience audiences have ever seen.
RealD’s next-generation hardware and software are deployed across the world’s largest 3D network. First deployed in 2005, the RealD Cinema System works with a single digital projector and is the most widely deployed 3D projection system in the world. RealD’s mission-critical 3D visualization technologies are used by Fortune 500 companies to enable the simulations and inventions of cutting-edge products, military and research organizations such as NASA.
hello friends,
have you ever feel scared when you get remembered any old incident or when you remind your old memories? if yes then now medical science have started research to change the stored memories in our mind which makes us scared when you remember it.
In this tests researchers have shown a horror film to a subject then she was very scared then after whenever she thinks about that movie or heard from someone she was so afraid.
then she was again shown that movie again to make her memories fresh or call her memories.
actually when our memories are called then after call the are again stored in our brain so researchers have made change in memories and and stored in subjects mind.
now you can think what can be possible in medical science.
this is the link for downloading google crome image file…
http://gdgt.com/google/chrome-os/download/
its compressed size is 300 mb and uncompressed is 700 mb.
1.) To use the vmdk file, open VMware and create a new virtual machine. One of the options will be to use an “existing virtual disk.” (In VMware Fusion, this is the last option below, “use operating system disk” and “use OS disc image file.”)
2.) Make sure your VM is set to use bridged networking, rather than NAT.
2.) The username and password to login to Chrome OS / Chromium OS is your google account!
Alternatively, if you don’t have VMware, some users have had luck getting this image to run using VirtualBox, which is a free cross-platform (Windows / Mac / Linux) virtual machine created by Sun Microsystem. You can download VirtualBox here:
http://www.virtualbox.org/
for help from the given link you can see video for using it

Yesterday Nasa has launched Wise -eye mission to begin its survey of space. The spacecraft uses a telescope designed to see light in the infrared wavelengths.
Wise-eye will scan the entire sky using infrared light, it will take millions of images of the objects never seen in history.
This mission will uncover objects which are not seen till now like cold stars, galaxies, some dark matter near earth asteroids and comets. This will help to find out the answers of questions stars galaxies and planets origin.
WISE’s will find near-Earth objects, asteroids and comets, with orbits that come close to crossing Earth’s path. It will find hundreds of these bodies, and hundreds of thousands of additional asteroids in our solar system’s main asteroid belt. this will be done by measuring objects’ infrared light, astronomers will get the first good estimate of the size distribution of the asteroid population.

f you want to check what processes are running on a remote server, there are many ways to get this information. Possible ways include connecting to the server with Remote Desktop to run Task Manager and using the Reliability and Performance Monitor (Perfmon). Another option is to use the Sysinternals PsList tool, which can get you this information remotely and quickly.
PsList is part of the PsTools Suite. I still challenge myself to fully migrate to a PowerShell environment, but I still use tools that are command line (DOS) driven in lieu of PowerShell scripts due to number of lines and typing required. However, PsList can be run from a PowerShell console if you have made the transition.
PsList is a standalone executable and can be run against a remote computer. To run against a remote computer, users with Administrator-level permission can determine the list of processes running on a Windows Server. In this example, using PsList with the following command will return the processes running and update continuously every two seconds against the server named BEATBOX:
pslist \\BEATBOX -s
The continuous refresh makes the PsList display function like an instance of TaskManager but running remotely from another system.
Last week, I came across a Gadget download of the Chrome OS beta. It is provided as a virtual machine, making it painless to try without dedicating equipment. The beta is provided two ways – as a VMware virtual machine (VMDK disk format) or a Sun VirtualBox virtual machine (VDI format). After downloading the appropriate image from Gadget, it can be quite easy to get started. If you want to go through this download on your own, the free beta download is here, and there are plenty of discussions on how to fix common areas on the Gadget site as well.
In my situation, I am running the Chrome OS beta on a VMware ESXi host. While I am not aware of a direct install of Chrome OS, running it as a virtual machine is adequate for my needs to evaluate the platform. This is how I evaluate all new operating systems, so it is a good way to start.
Powering on the Chrome OS beta gives us an authentication screen, as shown in
Once inside the beta, simply running the Chrome browser is a predictable experience. Among the points of interest is a task manager that allows you to see performance statistics and run processes on the browser OS, including a running tab of goats teleported, as shown in Figure.
