Atom-sized Storage Could Change the Face of Data and Memory (Jul 26, 2016)
The secret to our data storage woes could be an atom or, more precisely, a grid of them. Atoms, the smallest building blocks in nature, have their appeal as a storage medium. We certainly need a new storage paradigm. Something that takes up considerably less space than the current large-scale solution: data centers. Dotted throughout the world, data centers are like highly organized versions of our basements, crammed full of stuff we only occasionally access, but still consuming vast amounts of ...

Keeping Big Data Cool at SDSC (Jul 23, 2016)
When most people think of a supercomputer center, they may think of one massive computer performing a single task. Inside the data center at the San Diego Supercomputer Center (SDSC) at the University of California San Diego, however, there are several large supercomputer systems, each performing multiple tasks simultaneously across a wide range of science domains. Keeping SDSC’s main data center cool enough so that its Comet and Gordon supercomputers, among smaller clusters, don’t overheat ...

Big Data and Its Developer Fallout (Jul 23, 2016)
As the internet social turf wars continue to mature, the land grab is becoming much better understood. With a few companies controlling 95 percent of the social data, the internet is more closed and much more controlled than ever before. The term (and concept behind) big data has been thrown around a lot over the past 15 months. What I’m referring to here is user data, primarily from social businesses that can be leveraged to build other apps and businesses if done within the confines of a com...

Hanging Out with Anki's Cozmo, the Toy Robot Putting AI at Our Fingertips (Jul 22, 2016)
When playing with Cozmo, Anki’s palm-sized artificial intelligence robot, it’s easy to forgot all of the engineering and software running behind the scenes. Every action, from Cozmo’s audible chirps of victory when it wins a game to its childlike mannerisms when it recognizes your face, conceals tens of thousands of lines of code. When the product launches this October, Anki hopes consumers won’t think of its AI robot as undecipherable technology. Instead, the company wants people to won...

Supercomputing for Better Fireworks (Jul 17, 2016)
To improve the bombastic experience, scientists took to supercomputers to concoct the perfect pyrotechnical recipe. Fireworks accompany all types of celebrations, from weddings to sporting events, to political rallies, and holidays. They achieve their expected effect when a launched packet of combustible particles detonates overhead. As the ensuing explosion forces these grains outward — unlike in the vacuum of space where they would travel forever outward — the drag in our atmosphere slows ...

Now Hiring: Women With These Degrees (Jul 15, 2016)
Picture a software engineer or video game developer. What do you see? Chances are it's not a woman. One reason is that women are still very much in the minority in computer sciences and engineering. Even though there are many efforts underway to encourage girls from a young age to pursue STEM fields, the pipeline of women coming out of college with degrees in engineering and computer science is still very small relative to men. That's also why talented women entering the workforce with degrees i...

Analog Computing Returns (Jul 15, 2016)
A transistor, conceived of in digital terms, has two states: on and off, which can represent the 1s and 0s of binary arithmetic. But in analog terms, the transistor has an infinite number of states, which could, in principle, represent an infinite range of mathematical values. Digital computing, for all its advantages, leaves most of transistors’ informational capacity on the table. In recent years, analog computers have proven to be much more efficient at simulating biological systems than di...

We Need To Talk About AI And Access To Publicly Funded Data-sets (Jul 14, 2016)
For more than a decade the company formerly known as Google, latterly rebranded Alphabet to illustrate the full breadth of its A to Z business ambitions, has engineered an annually increasing revenue generating empire which last year pulled in ~$75 billion. And it’s done this mostly by mining user data for ad targeting intel. It’s an abstract idea for starters, and a personal cost that’s far harder to quantify given how unclear it is what Google really does with the data it gathers and pro...

Require Computer Science But Don't Replace Other Classes (Jul 14, 2016)
Computer science, if installed in all of Iowa's schools, should not replace other classes and instead be a main course, according to a committee with the Governor's STEM Advisory Council. "We believe it is time that computer science is recognized as a core discipline," Mark Gruwell, co-chairman of the computer science committee, told members of the Council. Gruwell told the Register the group does not want computer science class time to supplant math, foreign language or other coursework. If the...

Obama, NIH Announce Big Data Gathering Push For Precision Medicine (Jul 13, 2016)
One could be forgiven for experiencing a bit of hopeful, skepticism in response to U.S. President Barack Obama Administration’s statement in May regarding re-energizing the “War Against Cancer.” The war against cancer is a many-decades old effort with mixed results – great progress in many areas but matched with disappointment in others. Winning the war still seems rather far-off. Precision Medicine is a powerful idea – mostly marshaling insights from varying genomics technologies and ...

Extortion Extinction: Researchers Develop A Way To Stop Ransomware (Jul 13, 2016)
Ransomware - what hackers use to encrypt your computer files and demand money in exchange for freeing those contents - is an exploding global problem with few solutions, but a team of University of Florida researchers says it has developed a way to stop it dead in its tracks. The answer, they say, lies not in keeping it out of a computer but rather in confronting it once it's there and, counterintuitively, actually letting it lock up a few files before clamping down on it.



Computer Science Is Future-Proof (Jul 12, 2016)
Here are some of the more outlandish predictions for the jobs people might hold in the future: mind-uploading specialist, personalized microbiome steward or de-extinction zoologist. I, for one, am looking forward to my second career in 2030 as a professional "triber" and crowdfunding specialist. No one can really say for certain what the jobs of the future will be. A former educator with whom I recently met argued that uncertainty about the future job market means that giving students opportunit...
