Some pretty big news in under 140 characters. There’s been talk for months about whether the popular micro-blogging social media would go public. But Twitter’s filing was a bit unconventional.

We already know the NSA trades data with U.S. allies. But the latest document leak from Edward Snowden suggests all of that phone and online data the NSA is sucking in is being shared in raw form with at least one country: Israel. And today LinkedIn throws open the digital doors to, of all people, teenagers.

In a study published today, researchers at the University of Miami say that, thanks to modern computing technologies, extreme events in financial markets, that often happen within a few milliseconds, are on the rise. And Apple announced a host of new products this week. Two new iPhones, a new operating system iOS 7, and a streaming music service iTunes Radio. But the announcement that might truly push the boundaries of modern technology is the company’s new fingerprint scanning tool. Apple’s new iPhones have scanning hardware and software that will unlock the phone itself. It also could unlock new legal and hacking challenges.

Last week we learned the NSA was trying to weaken encryption online. Now Google has announced it’s trying to step up encryption on all its data. But one suggested solution for users trying to avoid surveillance is to operate on an entirely separate network. A so-called mesh network is made of phones and other devices that talk to each other without the help of an Internet service provider.

We’ve now learned that the NSA was not only conducting surveillance but also working to undermine the last ten years of encryption online.

Whether you’re Google or a company that builds encryption tools, you’re vulnerable to the NSA.

Online payment company PayPal has released a new version of its app for Android and Apple’s iOS operating systems. The company is hoping it will make a big difference in a tricky area: Mobile e-commerce. And Marketplace Tech reporter Queena Kim joins us to play Silicon Tally.

This week Washington is debating the very real possibility of military intervention in Syria, from air strikes to so-called boots on the ground. But there’s another conversation happening around whether the U.S. should attack President Assad’s regime with cyber warfare. So what might a cyber attack against Syria look like, and what would the repercussions be? 

We all know about the data being collected on us by advertisers while we’re online. Serving us ads that are more relevant to our interests? Sure, great. But take the amount of data – and what companies can do with it – to the extreme. Maybe your smart fridge tells a food company when you turn into a Cookie Monster, and suddenly you get a text from a cookie company. There are plenty of possibilities.

Today is a bit of a Kodak moment. At least, the company is hoping for that. Expected to emerge from bankruptcy today, the old camera and film maker has a new focus: a future in printing. And lots of people are logging back into the old campus intranet this week, as students, professors and administrators return to colleges and universities around the country. And you know what that means. We’re starting yet another academic year of campus-wide hacks. Can it all be avoided?
