5:41 PM | D-Wave: Truth finally starts to emerge
Two years ago almost to the day, I announced my retirement as Chief D-Wave Skeptic.  But—as many readers predicted at the time—recent events (and the contents of my inbox!) have given me no choice except to resume my post.  In an all-too-familiar pattern, multiple rounds of D-Wave-related hype have made it all over the world [...]

5:30 PM | The Lost Story of E.T.'s BMX Stunt Riders
BMX biking became a phenomenon in the 1970s as kids started imitating off-road motocross races with their own bicycles. By the middle of the decade, BMX racing was an organized sport, and bicycle companies were designing bikes specifically for BMX competitions. But the success of one of those brands can be traced back to one specific moment: the day Steven Spielberg's E.T. the Extraterrestrial premiered in theaters. That brand was Kuwahara.Kuwahara, along with a group of local bikers from […]

5:04 PM | Quote o' the day: Do what the moody guy on the Ducati does
In a sub-thread on Reddit about the advantages of IntelliJ vs. Eclipse, Moerderhai wrote, ...So I tried this Intellij thing that the moody guy who rode a Ducati really liked.... Moerderhai was then enlightened, he found a chickadee that laid golden eggs, rainbows and unicorns began wandering through his cubicle, and so on. (I don't know why I found this amusing.)

5:00 PM | More Altair 8800 Than Apple II
Mechanical Engineer Jeff Landrum makes a great case for why today's desktop 3D printers are more akin to early Altair 8800 computers than the Apple II. He cites the same challenges facing 3D printer adoption that we've discussed, listing mechanical and software hurdles such as infill algorithms and user-friendly interfaces that need to be improved before 3D printers can be viable consumer products.

2:01 PM | Another day at the Big Data: Theoretical and Practical Challenges Workshop
Yesterday was the second day at the Big data: theoretical and practical challenges - May, 14-15, 2013 - IHP, Paris. A big thank you to both Francis Bach and Michael Jordan for organizing the meeting. Francis tells me the slides will be available at some in time so we can come back to specifics of some presentations but for the time being, here are just a few notes that drew my attention because of their relevance to some of the subjects we discussed here […]

12:32 PM | Extreme syntax
In his book Let Over Lambda, Doug Hoyte says Lisp is the result of taking syntax away, Perl is the result of taking syntax all the way. Lisp practically has no syntax. It simply has parenthesized expressions. This makes it…Read more ›

7:00 AM | Google I/O: How Google Now Is Bringing Search Closer to Science Fiction
The heart of Google’s product line is search, and there can no longer be any doubt that Google Now is the future of the company's efforts. At the first day of Google I/O, the search giant cavorted itself like it was putting on a real developer conference. There were developer console updates, new tools, and APIs. Still, things came back to Google Now, and that’s no surprise.The Search app on Android received an update, which was demoed on stage. Along with some new info cards, Google Now […]

4:42 AM | Graduate Student Traps
Can we help avoid parallel repetition of mistakes? Irit Dinur has recently again shown a wonderful skill at re-conceptualizing an area that had seemingly been well worked out. A notable previous instance was her re-casting the proof of the PCP Theorem as a progressive amplification. Now she and David Steurer have posted a new paper […]

6:50 PM | The Physical Relief of the Escape Key
Here's a situation that should sound familiar. You're using your computer. An application locks up. You click on the window, anyway, to see if it does anything. The application hangs. It's not responding. Instead of giving up, and walking away, you keep clicking--maybe on that application, maybe elsewhere on the desktop. Click. Click. The longer you wait, the angrier you get. Click click click. Your computer is no longer under your control. Clickclickclickclickclickclickclickclickclick.The most […]

Watch or listen to the news in any city and you’ll be fed a stream of numbers: traffic times, weather forecasts, sports scores and financial reports. All this data gives a quick, surface snapshot of the city on any given day — what happened last night, what’s happening right now, what will happen over the […]

6:00 PM | DNA Barcoding is the Modern Tricorder
Watching certain episodes of the the original Star Trek, it's hard not to laugh at the show's 1960s-era technology transplanted into the future. But one of the series' most famous pieces of technology, the science tricorder, is still ahead of its time--it may be bulky, but it's still able to identify any known life form in a way modern scientists dream of. More than forty years later, we're still jealous of the tricorder, but scientists have actually figured out how to replicate its technology […]

5:30 PM | Google I/O: Unlocked Galaxy S4 with Stock Android
It may not be one of the infamous freebies Google is giving away at its I/O conference, but the Samsung Galaxy S4 will be sold by Google starting on June 24th. This version of the S4 will run a stock version of Android 4.2, providing what Google is calling the "Nexus user experience." Timely Android updates are promised. It'll also be bootloader unlocked and will support GSM LTE basebands (AT&T and T-Mobile). The phone, with 16GB of internal storage, will be priced at $650. This is the one […]

5:00 PM | Google I/O: "All Access" Music Service
One of the first big consumer announcements at today's Google I/O keynote: Google is launching a music subscription service in the vein of Spotify and Rdio. It's called All Access, and give subscribers access to 2 million songs at launch. Like other streaming services, All Access will feature personalized recommendations curated by "music editors." It'll also generate radio playlists, but will let users reorder tracks in that playlist and even remove unwanted songs ahead of time. That's a […]

10:30 PM | Bizarre Spycraft: The Most Questionable CIA Operations
Espionage is one of those occupations where there seem to be no rules, at least in the conventional sense. Sure, we can assume that spies engage in plenty of good old-fashioned infiltration (and seduction) in the name of information gathering, but the spy agencies of the United States and its enemies have also dabbled in some seriously weird side jobs. Today, we’ll spotlight ten of the most unlikely and bizarre methods of spycraft our government ever put into practice.

9:32 PM | A day at the Big Data: Theoretical and Practical Challenges Workshop
Today, I was at the Big data: theoretical and practical challenges workshop at IHP and liked it very much, at least the talks and was pleasantly surprised that this issue of phase transition being center to demonstration arguments. Michael Jordan talked about a new kind of (simple but seemingly powerful) K-means algorithm. Alexandre D'Aspremont presented some new work on the approximation bounds for sparse principal component analysis. Alfred Hero described phase […]

9:00 PM | Can a Supercomputer Simulate the Entirety of the Human Brain?
Science is constantly discovering new things about the human brain. Just last week we wrote about how the brain can track a 100 mile-per-hour fastball thanks to the visual cortex. Part of the cortex is actually predicting where a fast-moving object is going to be--a 100 mile-per-hour fastball moves 12.5 feet in the amount of time it takes a signal to travel from our eyes to our brain. It's the kind of small discovery that neuroscientist Henry Markram may completely overshadow in the next decade […]

Logitech’s series of Bluetooth Easy-Switch Keyboards are the best keyboards to use with most devices, due to the fact that they're a pleasure to type on, are widely loved by reviewers, boast extremely long battery lives, and come in Apple and Microsoft hardware-friendly configurations. They can be paired with up to three different devices at a time and switch back and forth between those paired devices at the push of a button.Single Use Keyboards Are LameA lot of people bite the bullet and […]

5:00 PM | Password Strength Meters Really Do Encourage Better Passwords
The meter sneers back at you, its bar only halfway filled. The red text is half warning, half condemnation. Password strength: Weak. What do you do? Maybe you delete your clearly unworthy password--a password you may have used on other sites. Or maybe you just go with it--what does that meter know, anyway?According to a new scientific study written up on Ars Technica, password meters do actually have a positive effect on some people as they set up their passwords online. What's interesting is […]
