A few weeks ago, Chris Dixon tweeted something thought-provoking:

What were the last Hollywood movies you saw about technology & the future that were optimistic? They seem to be systematically dystopian.

I happened to be sitting in a movie theater waiting for Iron Man 3 to start, so I tried to come up with a good counter-example. It’s a lot harder than I thought it would be. Then the pre-movie trailers starting playing. The new Will Smith (and son) flick, After Earth: dystopia. The new Guillermo del Toro flick, Pacific Rim: dystopia. Even the new Superman flick, Man of Steel, could be classified as a technological dystopia (more below).

Oh, Kim Dotcom. You just never stop surprising us. Just hours after Twitter finally rolled out its long-awaited Two-Factor authentication, the Megaupload founder is claiming to have invented the entire mechanism… and he's got a patent to prove it.

Fresh from closing its purchase of newsreading app Pulse, LinkedIn has made another acquisition to dive deeper into the mobile space. TechCrunch has found out, and confirmed, that the social network has aqui-hired Maybe, the social polling startup founded by Omar Hamoui -- the man who set up, ran and then sold mobile ad company AdMob to Google for $750 million.

Cloud encoding vendor Encoding.com launched Vid.ly a couple of years ago to provide video creators with a way to publish a single universal video URL and then have that content accessible on any device. Now it's providing a way to monetize those videos, thanks to an integration with ad delivery platorm FreeWheel.

GiftCards.com, a Pittsburg-based company that has been around for more than a decade and has sold 5 million gift cards, agreed to buy San Francisco startup Giftly to grow out a mobile platform. The terms of the deal weren’t disclosed, but Giftly had raised about $2.8 million from investors including Baseline Ventures, SoftTech VC, Floodgate, Thrive Capital, and Techstars’ David Tisch. Giftly’s acquisition follows a number of other ones. Karma was picked up very early by Facebook although it may not produce meaningful revenue for some time for the social network, according to its earnings results earlier this year. Another gifting startup, Giftiki, which pooled together people’s money to get gifts, was acquired by Launchrock. Giftly built a platform that avoided the hassle of individually dealing with merchants and point-of-sale systems. They came out with a

After hundreds of thousands of accounts were potentially compromised a couple months ago, Twitter today launches two-factor authentication through SMS to protect people from hacks and phishing scams on the web. Twitter's "login verification" doesn't work with its mobile apps, though, so you'll need to use temporary app passwords to stay safe when logging in on your small screen.

After scores of accounts were potentially compromised a few months ago, Twitter today launched two-factor authentication through SMS to protect people from hacks and phishing scams on the web. Unfortunately, it may not help shared accounts like big brands and news agencies where multiple people need to be able to log in and out but only one phone number can get the login verification codes.

For this week's episode of Founder Stories, I sat down with Ilya Sukhar, co-founder and CEO of Parse. The interview was taped days before Parse was acquired by Facebook last month. Parse is a cloud app platform that provides a set of SDKs that enable developers to focus on the execution of their application instead of rebuilding backend functionality for every mobile platform. Sukhar shares his experience of leaving Salesforce after his first startup, Etacts, was acquired and going through Y Combinator for the second time.

Another step for Adobe in its bid to become the go-to place in the cloud for those working in design and other creative industries: it is acquiring Thumb Labs, a bootstrapped, New York-based mobile app design agency. Jared Verdi, one of the co-founders of Thumb Labs along with Rich Kern, tells TechCrunch that financial terms of the Thumb Labs acquisition are not being disclosed. The news follows on from Adobe’s acquisition of another New York-based design startup, Behance, a platform for designers and others in the creative industries to share their work, which Adobe picked up in December 2012 reportedly for around $150 million. Earlier this month, Adobe put the Behance acquisition into context when it announced a massive push on its Creative Cloud strategy, with social/community features powered by Behance. Verdi tells TechCrunch that
