2:32 AM | Testing: OnePlus One Android Smartphone
We just posted our OnePlus One phone review, and I wanted to distill some of those thoughts in a post for anyone searching on Google or looking to find more information about the phone. As I said in the video, this is one of the best Android phones I've ever used. It's faster than the HTC One M8 and costs less off-contract than even Google's Nexus 5. And as of today, I'm still using it as my primary phone, as the benefits of its awesome battery life outweighs the disadvantages of its massive […]

10:13 PM | Engineering Alien's Original Xenomorph's Head
H.R. Giger's recent passing has brought to light some new accounts of the film production for which he was best known, Ridley Scott's Alien. The Strange Shapes fan blog recounts the little known story about how the original headpiece for the eponymous creature was created for infamous reveal shot. Apparently, two effects teams were hired to design a mechanized head for the scene--one at Shepperton studios which had previously build the R2-D2 droids for Star Wars, and a second led by Italian […]

9:35 PM | In Brief: Google to Expand Its Same-Day Delivery Service
Last week, I made my monthly trip to Costco to buy house supplies and food in preparation of the July 4th weekend. But in my haste to get out of the place before I wanted to kill myself, I forgot to pick up ketchup and gallon bags--essential picnic supplies. That was OK--I simply placed an order with Google Shopping Express on Thursday morning and had those items hand-delivered to my door by the end of the day, crowds avoided, shipping fee waived. "This simply can't last forever" is the thought […]

8:00 PM | In Brief: Here Is the Latest in Credit Card Skimmer Tech
Computer security reporter and expert Brian Krebs has been tracking the state of credit card skimmers--devices used to steal users' credit card information and PIN number at ATMs--for years, and his latest update cites a new report from the European ATM Security Team that shows just how small and discreet the newest generation of ATM skimmers can be. One design, made to work on US manufacturer NCR's machines, hides below the card reader "throat", making it difficult to detect. Skimmers are used […]

7:38 PM | Randomized Numerical Linear Algebra for Large Scale Data Analysis ( libSkylark: Sketching based Matrix computations for Machine Learning )
While reading up some RandNLA papers, I stumbled upon the Randomized Numerical Linear Algebra for Large Scale Data Analysis page which has been added to the collection of Highly Technical Reference Pages. Here is what the main page says: The Sketching Linear Algebra Kernel is a library for matrix computations suitable for general statistical data analysis and optimization applications.Many tasks in machine learning and statistics ultimately end up being problems involving […]

4:00 PM | The Best Android Smartphone for Your Network (June 2014)
We're in the thick of new phone season right now, which makes it a particularly perilous time to buy anything at all. Whether you're signing on for a two-year ride or doing a payment plan, it's a big commitment, and you don't want to regret it. Just like we do every month, we're going to go over the best devices on each of the big four US carriers and see what you should do.The Galaxy S5 and HTC One M8 are hitting their stride, but there's new reason to consider a device like the Nexus 5. And […]

3:05 PM | A puzzle puzzle
Jigsaw puzzles that say they have 1,000 pieces have approximately 1,000 pieces, but probably not exactly 1,000. Jigsaw puzzle pieces are typically arranged in a grid, so the number of pieces along a side has to be a divisor of the total number of pieces. This means there aren’t very many ways to make a […]

8:45 AM | Transmission of quantum entanglement through a random medium / Terahertz compressive imaging with metamaterial spatial light modulators
There are really two ways of producing some randomness. One way is to use a random medium and expect that the laws of transport will provide some sort of multiplexing. The other way is to engineer the random multiplexing. This week, we will have another example of the former but today we have an instance of both:One item that comes with papers that are behind walls: I need to have access to the second paper because I wonder about the "no moving parts" claim. You reader know my email, wink […]

10:11 PM | Sunday Morning Insight: Note By Note Cooking
Here is a small follow up to the Computational Cooking Sunday Morning Insight and related entries [1-3]. In the video below, Herve This shows his business card, i.e. an algorithm that can produce several structures for cooking. This is reflection of the paper featured in the last Sunday Morning Insight on the subject [3] (While the video is entertaining it is all in French though). Of note, here is a list of note by note cooking recipes performed by Pierre Gagnaire.The video […]

5:41 PM | Ellipsoid surface area
How much difference does the earth’s equatorial bulge make in its surface area? To first approximation, the earth is a sphere. The next step in sophistication is to model the earth as an ellipsoid. The surface area of an ellipsoid with semi-axes a ≥ b ≥ c is where and The functions E and F […]

4:57 PM | Sunday Morning Insight: Mathematical and Algorithmic Analysis of Network and Biological Data & Open problems from the 2014 Bertinoro Workshop on Sublinear Algorithms
Back in 2012, in predicting the future: The Steamrollers, we mentioned how sensors, especially in genomics would change our fields. On Friday, based on one of this earlier observation and continuous monitoring of the technologies involved, we mentioned that we are potentially witnessing a Second Inflection Point in Genome Sequencing ? and then wondered what it would entail briefly. In the second part of that prediction, we envisionned some of the algorithmic tools that might be used […]

2:16 PM | The Power of the Digi-Comp II: My First Conscious Paperlet
Foreword: Right now, I have a painfully-large stack of unwritten research papers.  Many of these are “paperlets”: cool things I noticed that I want to tell people about, but that would require a lot more development before they became competitive for any major theoretical computer science conference.  And what with the baby, I simply don’t have time anymore for the kind […]

2:14 PM | Reply to Rick Warren and Other Clergy Re Hobby Lobby and Federal Grants
Rick Warrent and others sent the most genteel invitation to perpetuate rank discrimination to President Obama this week. It is really quite eloquently stated. It asks that religious groups receiving federal grant money be allowed to continue discriminating against LGBT people, as a waiver from rules that would apply to others receiving those grants. My […]
