Our focus this week is women in tech and in recent days some of Silicon Valleys most powerful have been making headlines. The CEO of Hewlett Packard, Meg Whitman, leading her company’s backing of same sex marriage. Facebook’s Sheryl Sandberg has her new book on sparking a social movement in tech. And there’s Yahoo’s boss, Marissa Mayer, with a controversial ban on employees working from home. To start the week, Marketplace’s Silicon Valley reporter Queena Kim gives us an overview.

We’ve been covering the new Copyright Alert System that a group of major Internet companies launched this week to patrol for customers doing illegal downloads. The system will generate an escalating series of warnings. In theory, six strikes and a movie, music or software pirate is out. But what exactly happens on strike six? Harvard Law professor Jonathan Zittrain talks about how you might actually need to go to pirating re-education camp.

What online activity is worth the effort and actually leads to sales? Banner ads, Facebook likes, links to the time you were on public radio? Diamond Candle turned to a New York startup called SumAll, which has come up with a way to let clients see the stats on what online action caused what online reaction. SumAll’s founder Dane Atkinson says big Internet companies have a mountain of data on this, but making sense of it is the trick. And, a Carnegie Mellon post-doc student and Japanese researchers have just come up with a way to get smooth video from a thrown, spinning football. 

Facebook is responding to a call from top elected officials to crack down on Newtown school shooting conspiracy theorists. There are people who deny the terrible events in Connecticut in December and have been putting taunts and abuse on social media pages designed to help victims. Senators and a Congresswoman from Connecticut want Facebook to take the pages down; Facebook says no — but points out that it has been dealing with the issue and is in constant contact with families affected by the tragedy. And Yahoo’s new directive telling employees they can’t work from home any more has generated debate…but is it a good idea?

Google Glass: we know the company plans to have them available this year, and have them cost around $1500, but are these lens-less frames really a technological revolution? Joshua Topolsky, editor and chief of The Verge, talks with David Brancaccio about the experience of wearing them. And, a billboard in Peru that does more than catch the eye — it catches condensation and turns it into drinking water. 

Big U.S. tech companies are good at generating profits — and they’re also good at holding onto those profits when tax season rolls around. A report out this month details how some of the biggest names in the technology world avoid paying more taxes on revenue by storing assets overseas. 

Unlocking your phone might not be illegal, but you still might get in trouble with the law for doing it. It’s a gray area, and some people are upset about a rule change by the Library of Congress that could impact the way users do business with cellphone carriers. That’s why they started a petition to force the White House to address the issue — and the petition now has enough signatures to make the administration take another look. Meanwhile, how do you broach a different kind of rule: the one that governs the way you and your family interact with tech in the home? 

Yahoo’s homepage has gotten a makeover. Why? The website wants to be a place that people visit — and stay on. And we were all just starting to get used to the idea of 3D printing, and now here comes the 3Doodler — a pen that lets you draw with plastic. The company that makes the 3Doodler launched a Kickstarter campaign two days ago with a goal of raising $30,000. Since then the campaign has raised over $1 million. Maybe that’s because the price is right: $75.

Hackers managed to compromise a group of computers at Apple — much like they did earlier this week at Facebook. What does this mean? Macs, which are usually touted for their resiliance against viruses and hacks, are being put into the crosshairs by cybercriminals because they’re being used more often. And, there’s a new game coming out from the makers of ‘Halo,’ called ‘Destiny.’ The game’s makers say it’s the future. Is it?
