Facebook Reveals Details About its Infrastructure

datacenter.jpgFor a long time, Facebook has refused to be more specific than “more than 10,000” when it came to the question of how many servers it had running its website. Jeff Rothschild has now issued a more specific number, 30,000 with more servers being added daily, in his presentation at UC San Diego last week. Rothschild also revealed that Facebook stores 20 billion unique images, each in four sizes and that it serves 600,000 images per second.

Rothschild also mentioned that Facebook’s logged data accounts for 25 terabytes of data per day. He also said that Facebook now has 230 engineers, which means that there is one engineer per 1 million+ users.

PwnageTool 3.1.4 Adds Support for iPhone OS 3.1.2

pwnagetool3-1-4.pngA few days ago, blackra1n was released for Windows, which supported jailbreaking iPhone OS 3.1.2. The iPhone Dev Team has now released PwnageTool 3.1.4, its Mac OS X-only jailbreaking tool, which supports iPhone OS 3.1.2. The update supports all three generations of the iPhone. It also supports the first and second generation iPod touch, but a second generation iPod touch must already be jailbroken to use this update. PwnageTool 3.1.4 does not support the third generation iPod touch, but users of that device can instead use blackra1n, which supports a tethered jailbreak.

The update also keeps the baseband unlocked on the iPhone, which allows for the use other cellular networks, so long as the iPhone has been updated with custom IPSWs since iPhone OS 3.0. If an iPhone was already updated to 3.1.2 with the official firmware from Apple, there is currently no solution for unlocking the baseband.

The process for unlocking an iPhone 3GS that has already been updated to iPhone OS 3.1.2 involves an exploit that the Dev Team believes will soon be patched by Apple and they are urging iPhone 3GS users to get their EDIC hashes for 3.1.x, as it may prove important for future updates.

Early Chrome OS Build Leaked

chromeostheme2.pngAn early build of Google Chrome OS has been leaked after it was discovered amongst the Chrome (that is the browser, not the operating system) daily builds. Google has since pulled the build from its public site, but not before Jonathan Frederickson was able to download it. TechCrunch reports that Frederickson has released the build to the public and has also taken some screenshots of the operating system.

A computer running Debian or a Debian-based Linux distribution is required to use this build. It is an early build of the OS, meaning that many features are absent and it is prone to bugs and crashes.

Google Chrome OS is a lightweight, Linux-based operating system targeted at netbooks. It will be released in the second half of 2010.

Twitter Announces SMS Partnership with Bharti Airtel in India

airtel.pngTwitter announced that it has partnered with Bharti Airtel to bring Twitter SMS support to India. Bharti Airtel customers are now able to send tweets at the standard rate and receive them for free.

Twitter cites the abundance of mobile phones even in areas where most people do not have access to the Internet as the reason for its push to partner with mobile carriers in various countries, which it will continue to do as long as there is a demand. It also mentions the way that people use Twitter via mobile phones during emergencies:

“We have seen people use Twitter to help each other during fuel shortages, track the spread of wildfires, check in during earthquakes, organize major charitable events, spread urgent news efficiently around the world, and much more”.

Bharti Airtel customers in India can send “START” to 53000 to get started using Twitter on their mobile phones.

Twitter Streamlines Reporting Spam

twitterreportspam.pngTwitter has added the ability to report an account for spam right from the sidebar on that account’s page. When you report an account, it can no longer follow you or reply to you and a notice is also sent to Twitter’s Trust and Safety team, who can then take appropriate measures. The process is not automated, so that a group of angry users cannot get an unpopular but legitimate account banned.

This process is much more efficient and streamlined than the old one, which required you to follow @spam and then send a direct message with the name of the spammer.

Facebook Used to Apprehend Fugitive

sopo.jpgA fugitive from the United States has been caught with the help of Facebook, according to The Next Web. Maxi Sopo, a 26 year old from Cameroon, moved to the United States in 2003 and began to sell roses in Seattle nightclubs. Later, he moved on the bank fraud, falsely obtaining more than $200,000. After learning that he was being investigated, Sopo crossed the border to Mexico in February.

While living in the popular tourist destination of Cancún, Mexico, Sopo continued to post status updates to his Facebook account about his great experiences in Mexico. Sopo’s mistake came when he befriended a person on Facebook whom he had met in some of the city’s nightclubs. Presumably unbeknownst to Sopo, the person was formerly a United States Department of Justice official, a fact which he mentioned on his Facebook account. While Sopo’s Facebook account was private, his friends list was not and Assistant U.S. Attorney Michael Scoville looked through it. Upon finding the former DOJ official amongst Sopo’s friends, Scoville arranged to talk to the person.

The collaboration led to the apprehension of Maxi Sopo, who is currently in a Mexico City jail awaiting extradition to the United States. According to the Guardian, Sopo faces charges of bank fraud along with another man, Edward Asatoorians, who has already plead guilty. The two are charged with asking others to falsify their income and take out loans for cars. This money was then instead used to fund Asatoorians’s business and a trip to Las Vegas. Asatoorians is likely to face at least five years in jail, while Sopo may face up to 30 years.

Arthur Levinson Resigns from Google’s Board of Directors

arthur-levinson.jpgArthur Levinson has resigned from Google’s Board of Directors, which had served on since 2004.

Eric Schmidt, the CEO and Chairman of Google, described Levinson’s role at Google thus:

“Art has been a key part of Google’s success these past five years, offering unvarnished advice and vital counsel on every big issue and opportunity Google has faced…Though he leaves as a member of our Board, Art will always have a special place at Google.”

Levinson also described his experience at Google:

“Working with Eric, Larry, Sergey and the whole Google team has been a remarkable experience for me. I greatly admire what they’ve built and have no doubt that Google has a terrific future”

Levinson is also a member of Apple’s Board of Directors, as well as Google’s, according to TechCrunch, and his resignation comes amidst an FCC investigation that involves the two companies and AT&T. Whereas Apple and Google were once involved in a good business relationship, with Google’s CEO Eric Schmidt serving on Apple’s Board of Directors, this has since changed after Apple removed all Google Voice apps from the iPhone App Store this July. Not long after Apple did that, Schmidt resigned from its Board.

While Schmidt previously urged Levinson to stay on the board of both companies, Apple may not have been as supportive.

blackra1n Released, Jailbreaks iPhone OS 3.1.2

blackra1njailbreak.JPGThe iPhone Dev Team, creators of the popular iPhone jailbreaking tools PwnageTool (Mac OS X) and redsn0w (cross-platform), have yet to include support for iPhone OS 3.1.2 in their programs, but now there is an alternative for Windows users, blackra1n. blackra1n is a Windows-only jailbreaking program that supports all of the iPhone and iPod touch models. However, only a tethered jailbreak is supported on the third generation iPod touch, meaning that you will have to plug it into your computer and re-run blackra1n to boot it. The jailbreak works for iPhones and iPod touches running iPhone OS 3.0, 3.0.1, 3.1 or 3.1.2.

blackra1n is not a carrier unlock and the iPhone Dev Team cautions against using it if you plan to use your iPhone with a different carrier, stating that:

“blackra1n is not a carrier unlock. You must always avoid updating your baseband to maintain your unlockability. If you use blackra1n to jailbreak 3.1 or 3.1.2, the steps you take before running blackra1n will prevent the unlock from working on your iPhone for potentially a very long time.”
