The Computer Chip That Never Forgets

In 1945, mathematician John von Neumann wrote down a very simple recipe for a computer. It would contain two key components: a central processing unit to perform calculations and logical operations, and a memory bank to store instructions and data.

Our computers and microprocessor-equipped gadgets still follow this basic recipe. But under the hood, of course, they are far more complex. No existing form of memory is good at everything. So to move instructions and data as fast as possible, engineers have had to compromise. Today’s computers use a smorgasbord of different memory technologies, exploiting the best parts of each.

Meet the Open Source PC That Fits in Your Pocket

The MNT Pocket Reform is a seven-inch clamshell with a real keyboard

The MNT Pocket Reform is an open source computer with a seven-inch display.

Open source computing is coming to your pocket.

MNT Research, creator of the Reform open-source laptop and ZZ9000 add-in board for Amiga computers, is going small for its next project. The MNT Pocket Reform has a seven-inch screen with a clamshell design that, when closed, will be less than five centimeters thick. If its perky purple facade looks a bit retro, that’s no surprise; the Pocket’s inspirations read like a ‘greatest hits’ list of pocketable computers.

“We had a moodboard with several classic handheld computers: Nokia N900, Atari Portfolio, Cambridge Z88, Blackberry, Game Boy Advance SP, Alan Kay's Dynabook,” says Lukas F. Hartmann, CEO and founder of MNT Research. “I have a Psion 5mx, which was kind of a benchmark for the keyboard.”

iRobot Crams Mop and Vacuum Into Newest Roomba

The Roomba Combo j7+ handles both hard flooring and carpet in a clever, non-messy way

Robots tend to do best when you optimize them for one single, specific task. This is especially true for home robots, which need to be low cost(ish) as well as robust enough to be effective in whatever home they find themselves in. iRobot has had this formula pretty well nailed down with its family of vacuuming robots for nearly two decades, but they’ve also had another family of floor care robots that have been somewhat neglected recently: mopping robots.

Today, iRobot is announcing the US $1,100 Roomba Combo j7+, which stuffs both a dry vacuum and a wet mop into the body of a Roomba j7. While very much not the first or only combo floor-cleaning robot on the market, the Combo j7+ uses a unique and very satisfying mechanical system to make sure that your carpets stay clean and dry while giving your hard floors the moist buffing that they so desperately need.
