Raspberry Pi becomes a math teacher through new Wolfram bundle

Source: http://www.engadget.com/2013/11/22/raspberry-pi-wolfram-bundle/

Raspberry Pi computers have already proven to be valuable educational tools, but they're largely blank slates until teachers (and curious owners) find the right software. As of today, that software search just got a lot easier. The company has reached a deal to bundle Wolfram Research's Mathematica app and its companion Wolfram Language with each copy of Raspbian Linux; every Raspberry Pi owner now has free tools for everything from learning math to sophisticated programming. The deal also brings a Remote Development Kit that lets tinkerers connect the Raspberry Pi to Mathematica on a regular PC. While the updated Raspbian download isn't yet ready, all existing users can run a command to install Wolfram's suite. Only some owners will need the bundle, but it could go a long way toward promoting math to a younger generation.

Stable Chrome OS update notches movable Shelf, Braille display support

Source: http://www.engadget.com/2013/11/22/chrome-os-update-braille-display/

Google has just released a stable version of Chrome OS, and while it's (sadly) not as huge as Chrome OS 32, it still comes with feature boosts for your device. Perhaps most notable is its newly added initial support for USB-connected Braille displays. Other than that, this stopgap follow-up to OS 31 tweaks the platform's looks, starting by letting you drag the Shelf (or the app dock) from the bottom to either side of the screen. The company has also moved the launcher icon to the bottom left and made it, along with the app icons and status tray, more touch friendly for Pixel users. What's more, if you use an avatar for either Chrome OS or Google+, you'll find your profile picture preferences synced between the two. Almost everyone can now download these changes, which come bundled with the usual security and performance fixes. If you own an Acer C7, an HP Chromebook 11 or an HP Pavilion Chromebook, however, you're going to have to sit this update out -- better luck next time.

$4 Billion Is The New $1 Billion In Startups

Music streaming company Spotify just raised $250 million at a $4 billion valuation. 

That sounds high, but $4 billion seems to be the magic number for today's biggest startups. Recent valuations have dwarfed Tumblr and Instagram's once-massive $1 billion buyouts.

Uber received a $3 – 4 billion valuation in August when it raised a $258 million round of financing led by Google Ventures. Pinterest raised at a $3.8 valuation in October. A few weeks ago, Snapchat was mulling over a new round at a similar valuation. Evernote hasn't raised a round in over a year, but it's likely near the $3 – 4 billion valuation range now. Dropbox doubled the magic $4 billion figure and is raising at an $8 billion+ valuation. Today, Spotify joined the $4 billion club.

Why have valuations gotten so much higher in recent months?

First, there's a lot of private money out there, and investors need to invest it somewhere. When late-stage VCs stumble upon startups that can become category leaders, they throw piles of cash at them.

Uber is the category leader in on-demand transportation and logistics. Pinterest is winning in the visual retail discovery market.

"When one of the big players emerge [in a market], then you have these big firms that need to deploy a lot of capital," says RRE investor Steve Schlafman. "A lot of these companies don't need to raise more money...the only way these companies are going to raise more money is on a much! higher multiple. But I wouldn't call it irrational exuberance. These are big spaces with likely one or two winners (transportation, music, discovery, messaging)."

It's important to note that a lot of high-valuation deals give investors preferred stock, not common stock.  That means their investments are much less risky. Even if a startup gets bought for less than its official valuation, the preferred stock still gets bought out in full — sometimes at a premium or multiple. If a startup's valuation increases, both preferred stock investors and the founders win big. Even if a startup goes to zero, preferred stock holders get their money back first — if there is any left — while a founder with common stock might lose everything. 

It's also important to remember that investors don't want marginal wins. They're after home runs, so it's in their best interest to keep promising startups private and flip them later for higher returns. Investors who put money in Instagram at a $500 million valuation, for example, probably didn't anticipate the company selling for a smaller, 2X multiple. 

To prevent startups from getting acquired early, some investors let founders pocket cash during fundraises. Founders are able to take a few million dollars off the table and become instantly rich, just like they would if they sold the company. Eliminating the financial lure of an acquisition keeps entrepreneurs focused on building longer-term businesses.  

Snapchat's co-founders, for example, reportedly pocketed $10 million each during their last round of financing. They're rumored to be taking much more than that off the next round of financing — whenever that officially closes.

Some of the valuations are the result of hype though. And sometimes aggressive valuations can backfire.&n! bsp;

"I think later stage investors are analyzing growth rates and size and using Facebook (and other public stocks) as a comp on valuation," one industry insider says.

"If Facebook stock is high, than those startups will get a high price if they continue to exceed expectations. This can be tricky though, as we saw with [recent] late stage deals ... When growth slows down, the pain is harsh and swift." 

Instagram would be worth $5B+ today. It buttressed FB stock & gave it's mobile strategy legs. Insanely smart,cheap acquisition by Zuck.

See How This 'Smart' Credit Card Will Replace Almost Every Card In Your Wallet

Source: http://www.businessinsider.com/coin-smart-card-walkthrough-2013-11

coin smart card

There's a new startup that's looking to completely reorganize your wallet.

It's called Coin. We first got wind of it last week when the company made a big splash in the tech press with the unveiling of its $100 "smart" credit card.

We talk about a lot of companies that claim to be changing the way we handle payments. Coin is different — they're just making the current system better by reducing the number of cards we need to have with us at any given time.

At first glance, the Coin doesn't look all that special. It costs $100 and looks like a sleek, simplified credit card.



It can be swiped at any register, just like your debit or credit cards.



But amazingly, it actually takes the place off all of those cards in your wallet.

There's An Electronic Currency That Could Save The Economy — And It's Not Bitcoin

Source: http://www.businessinsider.com/electronic-currency-2013-11

Electronic Money_Cover

The United States has been marred in slow economic growth and a weak recovery for years now. Unemployment remains high. This is despite extraordinary efforts by the Federal Reserve to stimulate the economy. This drawn out period of low inflation and high unemployment has gotten more and more people talking about a "new normal" of mediocre growth.

Economists have been looking for ways to give central banks more power to combat recessions and prevent these long, drawn out recoveries. Larry Summers laid out this major impending economic challenge in his recent speech at the IMF. Normally, when a recession hits, central banks cut interest rates to incentivize firms to invest and to spur economic growth. But when interest rates hit zero, those banks lose one of their most important tools to combat recessions. This is called the zero lower bound.

Hitting the zero-lower bound means that interest rates cannot reach their natural equilibrium where desired investment equals desired savings. Instead, even at zero, interest rates are too high, leading to too much saving and a lack of demand. Thus we get the slow recovery.

Until recently, we hadn't hit that bound. But since the Great Recession, we've been stuck up against it and the Fed has been forced to use unconventional policy tools instead. What Summers warned of is that this may become the new normal. When the next recession hits, interest rates are likely to be barely above zero. The Fed will cut them and we'll find ourselves up against the zero lower bound yet again and face yet another slow recovery.

So what's the answer?

University of Michigan economist Miles Kimball has developed a theoretical solution to this problem in the form of an electronic currency that would allow the Fed to bring nominal rates below zero to combat recessions. He's been presenting his plan to different economists and central bankers around the world. Kimball has also written repeatedly about it and was recently interviewed by Wonkblog's Dylan Matthews.

"If you have a bad recession, then firms are afraid to invest," he told Business Insider. "You have to give people a pretty good deal to make them willing to invest and that good deal means that the borrowers actually have to be paid to tend the money for the savers."

But paper currency makes this impossible. 

"You have this tradition that as it is now is enshrined in law in various ways that the government is going to guarantee to all savers that they will get [at least] a zero interest," Kimball said.

If the Fed lowered rates below zero in our current financial system, savers would simply withdraw their money from the bank and sit on it instead of letting it incur negative returns. The paper currency itself — because it's something that can be physically withdrawn from the financial system — prevents rates from going negative.

This is where Kimball's idea for an electronic currency comes in. However, unlike Bitcoin, which prides itself on its decentralization and anonymity, Kimball's digital currency would be centralized and widely used. He would effectively set up two different types o! f curren cies: dollars and e-dollars. Right now, your $100 bill is equal to the $100 in the bank. If you're bank account has a 5% interest rate, you earn $5 of interest in a year and that $100 bill is still worth $100. But what would happen if that interest were -5%? Then you would lose $5 over the course of the year. Knowing this, you would rationally withdraw the $100 ahead of time and keep it out of the bank. This is where the separate currencies come in.

"You have to do something a little bit more to get the negative rate on the paper currency," Kimball said. "You have to have the $100 bill be worth $95 a year later in order to have a -5% interest rate. The idea is to arrange things so let’s say $100 in the bank equals $100 in paper currency now, but in a year, $95 in the bank is equal to $100 in paper currency. You have an exchange rate between them."

"After a year, I could take $95 out of the bank and get a $100 bill or if I wanted to put a $100 bill into the bank, they would credit my account with $95."

Got that? After a year of a -5% interest rate, $100 dollars are equal to $95 e-dollars. This ensures that paper currency also faces a negative interest rate as well and eliminates the incentive for savers to hoard dollar bills if the Fed implements a negative rate. Presto! The zero lower bound is solved.

The benefits of this policy go even further though: We can say goodbye to inflation as well.

"Once you take away the zero lower bound, there isn't a really strong reason to have 2% inflation at this point," Kimball said. "The major central banks around the world have 2% inflation and Ben Bernanke explained very clearly why that is. It's to steer away from the zero lower bound."

He's right. Back in March, Ryan Avent asked Bernanke why not have a zero percent inflation target. Bernanke answered, "[I]f you have zero inflation,! you&rsq uo;re very close to the deflation zone and nominal interest rates will be so low that it would be very difficult to respond fully to recessions."

But if nominal interest rates are allowed to go below zero, then the Fed has ample room to respond to recessions even if rates start out low. This is another major benefit from eliminating the zero lower bound.

What Kimball, whose blog is titled Confessions of a Supply Side Liberal, is most excited about is moving beyond the demand shortfall the economy currently faces to the supply side issues that hold back long-term growth.

"If you care at all about the future of this country, one of the things you need to realize is we need to solve the demand side so we can get back to the supply side issues that are really the tricky thing for the long run," he said. "The way to solve the demand side issues that is the most consistent with not messing up our supply side is monetary policy and making it so we can have negative interest rates."

At the moment, e-dollars are still only a theoretical concept, but Kimball is hopeful that they could be put into action in the near future. He believes that if a government bought in, it could be using an electronic currency in three years and reap the benefits of it soon after. 

"This is going to happen some day," he concluded. "Let me tell you why. There are a lot of countries in the world and some country is going to do this and it's going to be a whole lot easier for other countries to do it once some country has stepped out."
