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 […]

9:25 PM | Adam Tour Diaries #7: A Whirlwind Weekend
I got this shot heading into our first TV station. (Or was it radio? It’s all a blur.)We had a busy weekend prepping and performing our first three shows in Oz.We are in the lovely and awesomely foodie town of Melbourne, where the crowds are incredible. I’ve been furiously adding and modifying and refining bits of the show (an endless process, I’m afraid), and if there’s one thing I’ve learned about myself, it’s that when I’m putting a ton of creative […]

5:00 PM | In Brief: Witness the Kilobot Swarm
Earlier this month, we wrote about how roboticists use swarms of ants as models for programming collective groups of robots, but past experiments in swarming bots (or drones) have only utilized dozens of machines. In a new demonstration of the open-source kilobots project, Harvard roboticist Mike Rubenstein shows off how a system of over a thousand tiny robots could organize themselves to elegantly form two-dimensional shapes. The kilobots--which unfortunately sound like "killerbots"--are to be […]

3:21 PM | Back to Work
Harvard classes start up in a few weeks, and officially, my sabbatical is over.  I'm back in my office, trying to get back into a Harvard routine.I notice that I've been very light in posting over my sabbatical.  After my term as chair, I was enjoying being in the background, hidden away a bit.  I'm not sure if I'll get back into blogging -- it seems already to be a technology of the past -- but I figure I'll start again and see what happens.So some short notes.  On my to-do […]

9:25 AM | Fastfood: Approximate Kernel Expansions in Loglinear Time - The Paper -
Compressive sensing is not the only place where multiplying a vector or a matrix with a Gaussian matrix is a big deal for large scale problem (see the recent Random Matrices Are Too Damn Large ! and Another Comment on " Random Matrices Are Too Damn Large !"). If you recall this is also a problem for Random Kitchen Sinks, a randomized version of AdaBoost (a connection with compressive sensing is mentioned here). There, the training set in Machine Learning is used as a dictionary in order to […]

6:30 PM | Time exchange rate
At some point in the past, computer time was more valuable than human time. The balance changed long ago. While everyone agrees that human time is more costly than computer time, it’s hard to appreciate just how much more costly. You can rent time on a virtual machine for around $0.05 per CPU-hour. You could […]
