Silicon Valley firms are presenting a rare united front in an effort to end a political logjam that has blocked high-tech immigration reform.

In an unusual show of support that underscores how important the topic has become, executives from Facebook, Google, eBay and other major tech companies sent a letter today to President Obama and congressional leaders asking them to fix immigration law by the end of 2013. The current system is broken, they say, blaming visa shortages, long waits for green cards, and difficulties bringing spouses and children to the United States.

"Because our current immigration system is … Read more

We're big on small tools that let us convert video clips into different formats that we can play on our various and sundry devices.

One more thing: freeware, please. Green Free Video Converter just happens to cover all those bases. It's free, it's easy to use, and it converts files to … Read more

A lot of people like to do some of their banking on their mobile devices, but one company says the smartphone isn't just for checking balances.

Windows 8 has its fans and foes, but Microsoft felt the time was ripe for a new look and feel for a product used by more than 1.2 billion people.

Julie Larson-Green, the new head of Windows product development, recently spoke with MIT Technology Review about the reasons behind the major changes in the latest version of Windows.

Touting the new Windows 8 Start screen, Larson-Green said that in the past Windows users worked at a desktop with a monitor. In her view, people typically launched one window, put it away, and then launched another window. But in Windows … Read more

Bike riding is already a more environmentally conscious pursuit than driving around in a car, but you can really take it to the green extreme with a bike made from 100-percent-recycled aluminum. ReCycle is working at raising funds on Kickstarter to put its first full run of bikes into production.

There are some nice design tweaks that make the ReCycle bikes stand out. The usual seat tube support is gone. Two of the models have belts rather than chains. The eco-friendly aspects go beyond the use of recycled aluminum. The bikes also have saddles and grips made from cork. … Read more

The more data centers are built, the more power is consumed.

The more power is consumed, the more people rely on that power.

The more we rely on the grid, the more chance there is, perhaps, that something will go wrong.

The more we become reliant on the cloud, such a calamity will annoy more people who are desperate to, um, watch Netflix or stare at Instagram.

Suddenly, a horizon-encompassing net grabs you and takes you away from everything you once knew. Things go from bad to worse as the commercial fishing net rises and the pressure change kills you.

This fate, which often befalls millions of smaller non-target fish around the world every year, could change with the invention of the sustainable SafetyNet, which today was named winner of the prestigious 2012 James Dyson Award for design. … Read more

Technology topics can mark a rare bipartisan area of political agreement: Both Mitt Romney and Barack Obama say they would make cybersecurity a priority, and both like to talk up government funding of basic research.

If you look a bit more closely, however, differences emerge. They're perhaps most marked over federal regulation, where the two major parties have long-standing disagreements, but also exist on topics like WikiLeaks, copyright legislation, and whether to levy a new tax on broadband providers.
