This final note today: For those of you into settling bets the old fashioned way, Japanese scientists have developed a robot so fast it can "win" rock-paper-scissors against a mere human every single time.
But here's the catch: The way it wins...is by cheating. It can react so quickly -- in just 0.001 second -- to what your hand is doing, that it knows what to throw out to beat you.
So, we're sticking with what we know. Paper always wins. Also, cheaters never win.
The Twitter IPO is set for Thursday, and the company's apparently pretty confident things are gonna go well.
Today it bumped up the top end of its proposed opening stock price.
It's now shooting for $25 a share.
That'd value Twitter at about $13.5 billion.
Not bad for a company that not so long ago wasn't much more than a very disorganized start up.
New York Times columnist and technology reporter Nick Bilton has written the first real history of the early days at Twitter, in a book called "Hatching Twitter."
He says his story debunks the "creation myth" that was spun by the Twitter PR machine.
"There's this thing in Silicon Valley where we have these creation myth stories that are created by the founders. They are usually something along the lines of 'this thing came to me on the back of a napkin and then became this multi-million dollar company and there's no turmoil or stress along the way. But the reality is it's quite the opposite of that. And there's no better place of that than the Twitter story."
Bilton says the story of Twitter is a story of loneliness. The story of four young men trying to connect with the world.
"I think it's not just these guys, it's us. It's our generation. You walk around today and you see everyone pecking away at these little four-inch screens in their hands and we're all looking to be connected to something. I think the big irony to me when I was reporting this book and what I found out was that there was no place that was bigger than Silicon Valley at the time Twitter was created. And these four guys were essentially trying to find connection through technology and it didn't exist so they built the technology. And in the end they all realized, or some of them realized, that technology will never actually connect us to other people in the way that human connections will."

If being in a terrible financial situation is a precondition for bankruptcy, Joel Hagen and Becky Billings were pretty good candidates for it.
In 2012, the couple, who live in Minnesota, wanted to declare bankruptcy. They had suffered through several years of rotten job prospects, which came courtesy of the lousy economy.
"We've been together for almost 6 years now and about 90 percent of that one of us has been either unemployed or underemployed," says Hagen.
They also have piles of debt. Joel started their relationship with about $30,000 in credit card debt, plus a roughly $100,000 mortgage. Becky had that and more from graduate school.
"I come with student loan debt," she says.
Becky and Joel managed to dump their mortgage through a short sale. But they still wanted to discharge some of their other debts in bankruptcy. The problem was they couldn't scrape together $1,300 to pay a lawyer. And they didn't want to waste money filling on their own in case they botched the paperwork.
You've heard of too big to fail? Becky and Joel were too broke to file.
As we talk about all this, Becky falls silent.
"I guess I'm going to cry about that a little," she says, wiping away tears. "It was hard."
For Becky and Joel, avoiding bankruptcy was not some big financial victory.
Melissa Jacoby teaches law at the University of North Carolina at Chapel Hill. She says it's easy to assume bankruptcy filings are down by about a third since the recession because Americans are better off now. But she says that's not necessarily the case.
"We don't always see a perfect a perfect alignment between good times and low bankruptcy filings," Jacoby notes.
Jacoby says if the economy were soaring, bankruptcies might actually spike. Credit standards would loosen and people would take on more risks -- and more debt.
"Some of the highest peaks of bankruptcy filings occur in very prosperous times. That certainly happened in the middle of the 1990s," Jacoby says.
Right now student loans are the only kind of consumer debt that's been rising steadily since the recession. But good luck discharging that kind of debt in bankruptcy.
Becky Billings says that's one reason she and Joel Hagen can't get any relief from bankruptcy today. "You have to keep the student loan debt forever and ever and ever," she says.
Becky and Joel are both working now. He does copy writing, she does marketing, they both judge high school debates. But their finances are still precarious. And student loan debt will hang over them for years to come.

A fever, lack of cough, and sick neighbors could help you assess your strep status at home. By measuring how many people have strep in the community, researchers say it could be much easier to figure out when it's time to go for the lab test.
