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 […]

8:35 PM | Reviewing Scales
I'm just about finished reviewing for CoNEXT (Conference on Emerging Networking Experiments and Technologies), and am starting reviewing for ITCS (Innovations in Theoretical Computer Science).  One notable variation in the process is the choice of the score scale.  For CoNEXT, the program chairs chose a 2-value scale: accept or reject.  For ITCS, the program chair chose a 9-point scale.  Scoring from 1-9 or 1-10 is not uncommon for theory conferences. I dislike both […]

8:00 PM | In Brief: How Glass Lenses are Made
Adam shared this awesome photo gallery documenting every step an Optician takes to make corrective lenses to fit custom glasses. Every step is described in captions, showing the transformation from a hockey puck-sized lens to something that fits in the customer's glasses. My favorite tool used is the "edger" a machine that takes a scan of the glasses bezel shape and cuts the glass to fit into that specific frame. I love that the whole process takes less than an hour, and even as quickly as 35 […]

5:00 PM | The Best Exercise Headphones
This post was done in partnership with The Wirecutter. Read the original full article below at TheWirecutter.comIf I were looking for a pair of headphones to use in my workout, I’d want the Relays by Sol Republic. They are hands down the most comfortable headphones to wear while being active. They sound good, stay put without chafing or tugging, are light and resistant to sweat, and have a lifetime of free tips (because you know those lil’ buggers love to get lost in a gym bag).I […]

4:26 PM | Down to a science
Seth Juarez quipped in an interview that when people say they’ve got something “down to a science,” they probably don’t mean what they’re saying. Science is making guesses and testing to see whether they’re right.   Related post: Take chances, make mistakes, and get messy

3:30 PM | Videos and Slides: Next-Generation Sequencing Technologies - Elaine Mardis (2014)
Last time I mentioned Elaine Mardis videos giving a summary of next generation sequencing the video shot up and garnered more than 127,893 viewers. Coincidence ? I think not :-)Here is the new survey on Next Generation Sequencing where she talks about the current PacBio and Nanopore technology add-ons to the lab. I note the biology people liking the term "massively parallel" sequencing. Anyway, those third generation technologies are very interesting because instead of cutting DNA strands in […]

3:20 PM | Long Live the Fall Workshop (guest post by Don Sheehy)
An announcement for the Fall Workshop in Computational Geometry, by Don Sheehy.  In all the conversation about SoCG leaving the ACM, there were many discussions about ownership, paywalls, and money.  This leads naturally to questions of ideals.  What can and ought a research community be like?  What should it cost to realize this?  Isn't it enough to bring together researchers and in an unused lecture hall at some university somewhere, provide coffee (and wifi), […]

9:09 AM | On Detecting Messaging Abuse in Short Text Messages using Linguistic and Behavioral patterns
The use of short text messages in social media and instant messaging has become a popular communication channel during the last years. This rising popularity has caused an increment in messaging threats such as spam, phishing or malware as well as other threats. The processing of these short text message threats could pose additional challenges such as the presence of lexical variants, SMS-like contractions or advanced obfuscations which can degrade the performance of traditional filtering […]

5:00 AM | A compressed sensing perspective of hippocampal function
This is a theory but the main question really is: how do we go using fMRI and similar technology to figure out if this is really what is going on ? Food for thought.A compressed sensing perspective of hippocampal function by Panagiotis C. Petrantonakis and Panayiota PoiraziHippocampus is one of the most important information processing units in the brain. Input from the cortex passes through convergent axon pathways to the downstream hippocampal subregions and, after being appropriately […]
