TechCrunch Aquired by AOL

As you may have already heard, the popular technology blog, TechCrunch, was recently acquired by AOL, which was announced on Tuesday by AOL’s CEO  Tim Armstrong, as well as the website’s founder, Michael Arrington on the stage at TechCrunch Disrupt.

They even signed the acquisition agreement on stage, in front of the audience at TechCrunch Disrupt. According to Armstrong, AOL has been interested in TechCrunch “for a while”.

In addition to the main blog, the acquisition also includes other TechCrunch sites, including CrunchGear, CrunchBase, and MobileCrunch.

Michael Arrington also posted the reasons why TechCrunch was sold to AOL in a blog post from the TechCrunch website, stating:

“The truth is I was tired. But I wasn’t tired of writing, or speaking at events. I was tired of our endless tech problems, our inability to find enough talented engineers who wanted to work, ultimately, on blog and CrunchBase software. And when we did find those engineers, as we so often did, how to keep them happy. Unlike most startups in Silicon Valley, the center of attention at TechCrunch is squarely on the writers. It’s certainly not an engineering driven company.

AOL of course fixes that problem perfectly. They run the largest blogging network in the world and if we sold to them we’d never have to worry about tech issues again. We could focus our engineering resources on higher end things and I, for one, could spend more of my day writing and a lot less time dealing with other stuff.”

FaceBook Downtime

If you’re a FaceBook user, chances are you’ve probably already heard about the two and a half hour downtime that the site faced yesterday, during which people were not able to access FaceBook’s website. Also affected were FaceBook’s “Like” buttons, which are used on a variety of different pages throughout the Internet. Yesterday’s downtime was the worst outage that FaceBook has experienced in over four years.

FaceBook’s Director of Engineering, Robert Johnson, has posted a note on his FaceBook profile, which explains what caused the website’s outage, which you can view at this link.

Basically, what happened was that an automated system, which checks for invalid configuration value’s in the cache and replaces them with updated values from the persistent store. According to Johnson, this process works well for transient problems in FaceBook’s cache, but does not work when the persistent store is invalid, as well.

When FaceBook made a change to a persistent copy of a configuration value, it was was interpreted as being invalid. Because of this, every client saw the invalid value and attempted to fix it, which involves making a query to a cluster of databases. All of the queries caused the databases to become overwhelmed, as there were hundreds of thousands of requests being made a second.

Also, each time the client made a query and received an error, it interpreted it as an invalid value and then deleted the corresponding cache key. Because of this, even after the original problem had been fixed, the queries still continued. As long as the databases were failing to service some of the requests that were being received, they were causing more requests themselves, thus causing a feedback loop, which did not allow for FaceBook’s databases to recover.

In order to rectify this problem, all traffic to the database cluster had to be stopped, which meant that FaceBook had to essentially be “turned off”, which is why users were unable to access the website. After the databases had recovered from this error, FaceBook allowed more people to access the website again.

In addition, the system that checks for and attempts to correct invalid configuration values has been turned off and other options for this system are being explored.

New Twitter

As you may have already heard, Twitter has announced some new updates to their popular social networking service, including a new design, as well as making the service work better with various forms of media, such as pictures and videos.

Twitter’s new design will feature links to your @replies, mentions, retweets, lists, and searches above your timeline, instead of on the right sidebar, like it was before this update. Instead, the right sidebar will feature users who recently followed you and vice versa, as well as your favorites and the list of trending topics.

Also, Twitter’s new design is more “media friendly”, as users can now view pictures, videos, and other media right in their timeline, rather than having to click on a link and go to a third-party website. Some of Twitter’s partners, which enable this feature are DailyBooth, DevianArt, Etsy, Flickr, TwitPic, TwitVid, YouTube, Vimeo, yFrog, UStream, as well as other partners.

The new redesign of Twitter also enables users to discover related content, which they can do by clicking on a tweet, which will provide users with a “details” pane that displays more information about the author or subject of the tweet. Some examples of what you may see in the “details” pane include @replies, other tweets by the user, a map where a geotagged tweet was sent from, as well as other things.

Another new feature would be Mini Profiles, which enable a user to find out more information about another user by clicking on someone’s @username. Doing this will display account information, the user’s bio, as well as their recent tweets.

According to Twitter, these new features will be rolling out over the next few weeks as a preview. During this time, users will be able to switch back and forth between both the new and previous version of Twitter.

The Creeps

If you’re looking for a new game to try playing on your iPhone or iPod Touch, perhaps you should try playing a game called “The Creeps!”, which is a fun tower defense game by Super Squawk Software.

When you first launch The Creeps!, you will see a loading screen, featuring the company’s name and logo. After the game loads, you will be taken to the game’s main menu, where you can view news, switch players, view the high scores, credits, get help with the game, as well as start the game.

When you tap on the “Start” button, you will be presented with the maps that you have unlocked and are able to play on, as well as some information about the level, such as the game type, how many waves of “creeps” you’ll have to defeat, as well as what defenses are available in a particular. There are also two arrows that enable you to switch between the three different game modes, which are “Survival”, “Endurance”, as well as “Door Buster”.

When you are ready to begin the game, you can do so by simply tapping on the map you’d like to play yon.

Once the game begins, you will have a few seconds in which you are able to place your towers, in order to defend against the various “creeps” or monsters that are trying to attack a character who is hiding in his bed. However, each tower costs money and you only start off with a certain amount, earning more when you defeat monsters. Towers can also be upgraded to increase range and firepower, but the upgrades also cost money. Also, you can still place towers once the monsters have started coming.

If some monsters happen to get through your defenses, getting to the hiding character, you will lose a hit point. Be careful, however, as your character only has 10 hit points and some monsters, such as a “boss”, cause you to lose two hit points if they get through your defenses. Once you run out of hit points, the game is over and you’ll have to try again, in order to get to the next level.

If you would like to try playing “The Creeps!”, you can download it from the iTunes App Store for free.

Google Instant Search

As you may have already heard, Google recently unveiled a new version of their search, called Google Instant. Google Instant enables users to essentially search as they type, with new search results being displayed as if a user has entered a search query and pressed the “Search” button.

Google has tested their new Instant Search feature before and states that while it was “thought-provoking—fun, fast and interactive”, it was also “fundamentally flawed.” The reason Google’s Instant Search was “fundamentally” flawed was because nobody wants search results for something that doesn’t really make sense, such as half of a word or a few letters. Google states that users want “search-before you type”, which means that users want search results for the most likely thing that they were searching for.

Some new features that are included in Google’s Instant Search are dynamic results, which means that search results are displayed as a user is typing, which can speed up searches, predictions, which means that the rest of your search query will be predicted and shown in light gray text as you’re typing it, which can help you get the results you were looking for more quickly. Another feature is the ability for users to scroll through the predictions that Google Instant Search has made.

Google also states that their new Instant Search saves the average user about two to five seconds per search, which will end up saving users 11 hours with each passing second. Also, Google will become the “core search experience” on for Google’s Chrome browser, Mozilla FireFox, Safari, as well as Internet Explorer 8.

Google Instant will also be offered to Google users in a variety of different countries, such as France, Germany, Italy, Russia, Spain and the United Kingdom when they are logged in and who’s browsers support Google’s new Instant Search feature. In the next few weeks and months, Google is hoping to expand their Instant Search feature to more locations and platforms.
