With much of it sold to Microsoft, Nokia will probably never be the same again. The next chapter in the Finnish company’s history will depend on how well it can reinvent itself.

Nokia, Once The World’s Biggest Mobile-Phone Maker, Is Planning The Next Bounceback

Nokia is also keen to talk up its other two businesses. The larger is HERE, its highly regarded maps division, which has most of the market for navigation systems built into cars. The smaller, Advanced Technologies, will have the job of licensing Nokia’s thousands of patents and coming up with more bright ideas. Risto Siilasmaa, the chairman and acting chief executive, calls it “our innovation engine”. Most of the uncertainty about Nokia’s future has to do with how well this engine fires.

Many people are still skeptical about Bitcoin at this point, but the recent high of $900 has certainly increased interest in the cryptocurrency. Now Bitcoin has a new supporter, none other than the maverick Sir Richard Branson himself.

Whether you’re planning to invest in it; mine it; or ignore it, it’s probably a good idea to find out more about it.

In his own words:

Bitcoins in space

I have invested in some bitcoins myself, and find it fascinating how a whole new global currency has been created. For people who can afford to invest a little in bitcoins, it’s worth looking into.

The battle for privacy continues.

Forward Secrecy at Twitter

On top of the usual confidentiality and integrity properties of HTTPS, forward secrecy adds a new property. If an adversary is currently recording all Twitter users’ encrypted traffic, and they later crack or steal Twitter’s private keys, they should not be able to use those keys to decrypt the recorded traffic.

Apple finally releases Clumsy Ninja and this latest Editor’s Choice app debuts with a video trailer.

This is a big change in how developers can showcase their apps.

Dropbox has released a new look for its iOS app..

The new iOS 7-inspired design is gorgeous.

The addition of AirDrop support is great news. I hope this marks the start of greater adoption of AirDrop as a way of sharing files on iOS.

The American Physical Society interviewed Elon Musk.

But even if someone has no intention of ultimately being a physicist, I still believe that the training of physics is excellent. So as they’re going through their academic career I would recommend studying physics as a good base and then a broad range of engineering courses and then some degree of specialization in an engineering field where it fulfills someone’s interest, and then arts and sciences courses, particularly history. And a few business courses are helpful so you at least know the terminology. You can probably do it with one accounting course, [although] I hate accounting. It’s worth it to have some business courses but you don’t need too many. And I wouldn’t recommend an MBA. I’d say no MBA needed. An MBA is a bad idea.

It teaches people all sorts of wrong things. They don’t teach people to think in MBA schools. And the top MBA schools are the worst. Because they actually teach people that you must be special, and it causes people to close down their feedback loop and not rigorously examine when they are wrong.

I hire people in spite of an MBA, not because of one. If you look at the senior managers of my companies, you’ll see very few MBAs there.
