9:04 PM | End of summer musings on (lack of) rejuvenation and (too much) service
Summer is supposed to be a season of rejuvenation for academics. While research and service obligations remain, we get a break from teaching. Theoretically, since teaching is the major part of my job, this should mean that my summer schedule is (a) more low key, (b) more relaxing, (c) less time consuming, and (d) less […]

6:09 PM | Ira Glass Spills His Worktime Secrets
I didn't have a chance to read this Lifehacker interview with Ira Glass when it was first posted, but I'm glad I found it in my Instapaper queue this morning. The voyeuristic appeal of the series is strong for me. I love the glimpses you get into the processes of different businesses and publications. Audio wonks will love the details of the This American Life recording setup (they record interviews using a $240 AudioTechnica shotgun mic), but the real gem of the interview is his best life […]

2:55 PM | DNA Sequencing, Information Theory, Advanced Matrix Factorization and all that...
In Improving Pacific Biosciences' Single Molecule Real Time Sequencing Technology through Advanced Matrix Factorization ?, I gave the following description of the matrix factorization:[1] The factorization has the following shape: Y = P X with Y a matrix representing the timed sequence coming out of all the cells, a rank-1 matrix X that is unknown with columns representing the full aligned DNA being sequenced and P represents an unknown (group) sparse matrix (with +1 elements) representing […]

12:10 AM | Exclusive: Kevin Tong and Tom Whalen's Info•Rama Art Prints
Artist Kevin Tong is one of my favorite movie poster designers. If you've watched the videos shot at our office, you may have noticed his Overview print mounted on our studio set wall, as well as his Avengers Iron Man print in my garage in Tested member videos. We've also shared his design process videos on Tested before, which are fascinating for anyone who appreciates Adobe Illustrator work. I've had the pleasure of meeting Kevin at various conventions like the Renegade Craft Fair and […]

3:00 PM | Optimization of Convex Functions with Random Pursuit - implementation -
Optimization of Convex Functions with Random Pursuit by Sebastian U. Stich, Christian L. Müller, Bernd GärtnerWe consider unconstrained randomized optimization of convex objective functions. We analyze the Random Pursuit algorithm, which iteratively computes an approximate solution to the optimization problem by repeated optimization over a randomly chosen one-dimensional subspace. This randomized method only uses zeroth-order information about the objective function and […]

1:45 PM | Hashing Summer School
Back in July I took part in the Hashing Summer School in Copenhagen.  This was nominally set up by me, Rasmus Pagh, and Mikkel Thorup, though Mikkel was really the host organizer that put it all together.The course materials are all online here.  One thing that was a bit different is that it wasn't just lectures -- we really did make more of a "summer school" by putting together a lot of (optional) exercises, and leaving time for people to work through some of them in teams.  I […]

5:00 AM | Maximum Entropy Hadamard Sensing of Sparse and Localized Signals - implementation -
Maximum Entropy Hadamard Sensing of Sparse and Localized Signals by Valerio Cambareri, Riccardo Rovatti, Gianluca SettiThe quest for optimal sensing matrices is crucial in the design of efficient Compressed Sensing architectures. In this paper we propose a maximum entropy criterion for the design of optimal Hadamard sensing matrices (and similar deterministic ensembles) when the signal being acquired is sparse and non-white. Since the resulting design strategy entails a […]

9:58 PM | Bits to Atoms: Building the Millenbaugh Motivator, Part 3
Progress on the Millenbaugh Motivator marches on! All the measurements have been made and a rough version has been modeled and approved by Adam. This week we take a look at modeling the final version and speccing hardware.I decided to tackle the ‘valve arms’ first since I wasn’t sure how to build them. They look relatively simple but on closer inspection there’s multiple compound curves, plus the forked portion at the back and I couldn’t easily build them using my […]

9:45 PM | Testing: Surface Pro 3 and Shield Tablet's Styli
Two things struck me while testing the Microsoft Surface Pro 3 and Nvidia's Shield Tablet, devices I ended up really liking. Both are ostensibly tablets, but the way I used each of them differed from how I used my iPad Mini. First, I rarely used held either of them like a notepad, with one or two hands gripping the sides. Most of the time, I had the Surface propped up in its "canvas" position using its kickstand on a flat surface, and kept the Shield Tablet propped up on a small makeshift […]

8:30 PM | Building and Testing a Custom RC Airboat
Sometimes you seek inspiration. Sometimes inspiration smacks you in the face. As I was walking down the clearance isle at Walmart, I was smacked in the face. They had a few kid’s kickboards on clearance. With my Mini Alligator Tours airboat experiences still fresh on the brain, I immediately thought that one of these kickboards could be the starting point of a scratchbuilt airboat.Sitting next to the Mini Alligator Tours, the wide stance and minimalist design of my DIY airboat is […]

4:00 PM | The Zoidberg Project, Part 12 (Finale and Recap!)
Even though The Zoidberg Project has been wrapped up for a while now, it’s not over. I got sidetracked back in May with the Gore Magala build for Capcom's Monster Hunter 4 Ultimate display, and I still owe you all one more article!So let's back track a bit….back to early April. Leading up to the debut at WonderCon, I had a ton of finishing to do on the Zoidberg costume. The feet that Carson and I sculpted and molded needed to be cast up and painted. We opted for a simple latex and […]

3:45 PM | In Brief: How Long Will Your CDs Last?
Media archiving is a noble yet labored pursuit, as archivists struggle to find and adopt new technologies and mediums that won't go obsolete. We've previously discussed the US Library of Congress's approach to archiving millions of pieces of video. Back in the 90s all sorts of analog media was being transferred to what was then thought to be an enduring platform: the compact disc. NPR's All Things Considered recently interviewed the LoC's head of Preservation, Research, and Testing Division to […]

3:01 PM | Improving Pacific Biosciences' Single Molecule Real Time Sequencing Technology through Advanced Matrix Factorization ?
If you watched Elaine Mardis' Videos and Slides: Next-Generation Sequencing Technologies you noted that in order to produce complete genomic data, sequencing technology needs long read technology (also called 3rd generation sequencing technology) like the Pacific BioSciences SMRT or the nanopore technology. In fact, any advances in medical techology will come from dropping the price of these instruments to even lower prices than what we currently seem to reach. One of the issue with long […]

6:33 AM | Year-end review
When I was a teenager I broke all the rules on Friday night. After dinner I would watch Louis Rukeyser’s Wall Street Week at 8:30pm, and I would be in bed an hour later. On new year’s eve, he had a special “year-end review”, during which he hosted “financial experts” who would opine on the stock market and make predictions […]

6:14 AM | Here's The Drill Designed for Space Mining
Like many good ideas, Dave Boucher’s Moon mining drill started as a sketch on a napkin. That was in 1999 (just one year after the space drilling adventures of Armageddon). But sometime this fall, his company Deltion Innovation’s latest prototype of a real Moon drill will go through one of its final tests. And with any luck, DESTIN — which stands for Drilling Exploration & Sample Technology Integrated — will be chosen to spearhead NASA’s lunar prospecting […]
