How to get the new Facebook 'Timeline' now

Timeline
Can't wait for Facebook to roll out "Timeline," the magazine-style makeover of profiles?

You too can be an early adopter. Just pretend you are a developer.

But warns TechCrunch's Greg Kumparak: The reason that Facebook has not yet turned on "Timeline" for all of its users is that it's not quite ready for prime time. So expect some bugs. Also, your friends won't be able to see the new design. And if you sign into your Facebook account from a different computer, your profile may go back to the old design.

1. Go to the Facebook developers page.

2. Click on the "Apps" button and give the app permission to access your information.

3. You will now find yourself on a page that gives you the option to "create new app." Click on that button.

4. Here you will enter an "app display name" and an "app namesake."

5. Read the "platform privacy policy" and check the box to agree to it. Click continue.

6. Click the "open graph" button on the left side.

7. Type in an action such as "watch" and "TV show" and click "get started."

8. Keep saving changes until you are done.

9. Wait a few minutes and then head to the Facebook home page. You will see a message to enable "Timeline."

Intel CTO Talks Up Many-Core Future


During the recent Intel Developer Forum (IDF), Intel CTO Justin Rattner discussed the swift drive toward many-core computing, noting that this is an important development for HPC as well as many other realms.

Among the demonstrations and previews of the “many-core age” to come, Intel’s CTO touched on the future of extreme scale computing. This topic gave the company a perfect opportunity to discuss their ten-year goal to create a 300-fold improvement in energy efficiency, moving power consumption down the scale to 20 picojoules per FLOP at the system level.

Intel’s Shekhar Borkar who works with DARPA’s UHPC project said that “today’s 100 gigaFLOPs computer uses 200 watts. By 2019, it should use about 2 watts, due to reductions in power required not only by the cores, but by the whole system, including memory and storage.”

IDF also provided Intel a window to discuss a concept chip, nicknamed Clarmont, which they say can operate at near threshold voltage and can scale from full performance to low power on less than ten milliwatts of power.

Rattner stressed that these and related developments at Intel wouldn’t be restricted to HPC—he pointed to a number of applications that showed 30 or more times performance improvements as the core count lifted to 64.

As MAC OSX requires hardware virtualization technology. go the following link and download the .msi installer file. install it. it will give you the all the specs of your processor. <<http://tiny.cc/jlhkx>>
  • if your processor does support this feature you can carry on. other wise try the hackintosh technique.
  • now download the snowy_vm_ware files from this site : http://www.filestube.com/0dc6afd55400ad5903e9,g/Snowy-Vmware-files.html
  • now download the MAC OSX iso file which will be used to install the MAC OSX on the virtual machine from here << http://tiny.cc/e0b26 >>
  • click on the first file to unpack all the nine zip files into one.
  • now you have all the files that you would need.
  • unpack the snowy_vm files that you just downloaded and go to the MAC OSX 10.6 (experimental folder).
  • open this file Mac OS X Server 10.6 (experimental).vmx remeber not to open this file ._Mac OS X Server 10.6 (experimental).vmx (it has a dot and underscore in the beginning) do not open it.
  • this will launch the vmware workstation or the vm ware player.
  • initially it will show on operating system found.
  • you will be shown a button at the bottom of your screen to change th CD\DVD settings. click on it and give it a path to the mac osx iso file that you just downloaded. adn then restart your virtual machine
  • it will automatically start the installation wizard of the MAC OSX
  • just click on continue by selecting your language.
  • then click accept as u accept there license agreement and all.
  • next u will see a screen showin the hard drive and the install, cancel and customize button.
  • click on the hard drive icon.
  • click on the cutomize button
  • a new window will open
  • in the chameleon boot loader check the chameleon_RC5
  • then expand the chameleon options and check the ethernet button and the graphics enabler
  • the expand the patches option and check the usb fix option
  • press ok and then press install
  • now your mac is being installed.
  • when the installation finishes go to the settings of the virtual machine and change the cd\dvd settings.
  • chaneg the dc/dvd from the mac 10.6.6 iso to the darwin_snow.iso. this file can be found in the folder where you unpacked the snow_vm files.

Difference Between 1G, 2G, 2.5G, 3G, Pre-4G and 4G

1G is the first generation celullar network that existed in 1980s. It transfer data (only voice) in analog wave, it has limitation because there are no encryption, the sound quality is poor and the speed of transfer is only at 9.6kbps.

2G is the second one, improved by introducing the concept of digital modulation, which means converting the voice(only) into digital code(in your phone) and then into analog signals(imagine that it flys in the air). Being digital, they overcame some of the limitations of 1G, such as it omits the radio power from handsets making life more healthier, and it has enhanced privacy.

2.5G is a transition of 2G and 3G. In 2.5G, the most popular services like SMS (short messaging service), GPRS, EDGE, High Speed Circuit switched data, and more had been introduced.

3G is the current generation of mobile telecommunication standards. It allows simultaneous use of speech and data services and offers data rates of up to 2 Mbps, which provide servcies like video calls, mobile TV, mobile Internet and downloading. There are a bunch of technologies that fall under 3G, like WCDMA, EV-DO, and HSPA and others.

In telecommunications, 4G is the fourth generation of cellular wireless standards. It is a successor to the 3G and 2G families of standards. In 2008, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100 Mbit/s for high mobility communication (such as from trains and cars) and 1 Gbit/s for low mobility communication (such as pedestrians and stationary users)

A 4G system is expected to provide a comprehensive and secure all-IP based mobile broadband solution to laptop computer wireless modems, smartphones, and other mobile devices. Facilities such as ultra-broadband Internet access, IP telephony, gaming services, and streamed multimedia may be provided to users.

PRE-4G technologies such as mobile WiMAX and Long term evolution (LTE) have been on the market since 2006 and 2009 respectively, and are often branded as 4G. The current versions of these technologies did not fulfill the original ITU-R requirements of data rates approximately up to 1 Gbit/s for 4G systems. Marketing materials use 4G as a description for LTE and Mobile-WiMAX in their current forms.

Google+: A Social Network Even Geeks Can Love?

Google+ may still be in its invitation-only early days, but with all the wild excitement and skyrocketing numbers of users, it's awfully hard to tell.

Quibbles about real-name policies notwithstanding, eager users from virtually every walk of life seem to be flocking to the new social network -- even those of us who are perhaps less than entirely socially minded.

It's not at all surprising, of course, to see your average, run-of-the-mill Facebook fan scampering over to check Google+ out. Such individuals, after all, would likely jump at any opportunity to share photos, updates and every manner of personal details with countless friends far and wide. They are extroverts, in other words, and they *will* share as often and as widely as they can... for more http://www.technewsworld.com/story/Google-A-Social-Network-Even-Geeks-Can-Love-72963.html

Mozilla building mobile OS to battle Chrome

Mozilla revealed preliminary plans today to take the Gecko engine that drives its Firefox browser and turn it into an open-source operating system that will eventually work on phones and tablets.

Called Boot to Gecko, it is known that the source code will be released to the public "in real-time," wrote Andreas Gal, a Mozilla researcher. Gecko is the rendering engine that powers Firefox and the e-mail client Thunderbird. By contrast, while Google's Androidmobile operating system is open source, the main development work on it does not become available until after Google has green-lit its publication--sometimes not until months afterward.

"We will do this work in the open, we will release the source in real-time, we will take all successful additions to an appropriate standards group, and we will track changes that come out of that process. We aren't trying to have these native-grade apps just run on Firefox, we're trying to have them run on the web," Gal said in a forum post. Mike Shaver, Mozilla's vice president of technical strategy, said that the Boot to Gecko apps won't use the Android SDK but instead run new and current Web app APIs....
