6:41 AM | In Brief: An Object Lesson on Scotch Tape
The New York Times has a lovely short story about the origin of 3M's Scotch tape, which was invented in the 1920s by an engineering-school dropout who spent two years experimenting with chemical mixtures becoming landing on a combination of cabinetmaker's glue and glycerin as the adhesive for the now ubiquitous masking tape. The other half of the invention was of course choosing cellophane (introduced in the US in 1924) as the backing for the transparent tape. The name Scotch, apparently […]

5:00 AM | Number Spiral Mandalas with HTML Canvas
12-Spiral in HTML Canvas (Primes highlighted in red) Mathematics is about exploration, not the rote memorization of algortithms. It’s about finding patterns, appreciating how numbers relate to one another. That’s why I love programming. Much of writing code involves experimentation with mathematics, tweeking a variable to see what comes out of a complex function. It’s […]

11:57 AM | Pour la Science de Juillet
L'été, il arrive que je lise Pour la Science un peu distraitement, lunettes de soleil sur le nez et bière à la main. Mais cette année c'est différent : le numéro 441 de juillet est passionnant du début à la fin. Dans ce numéro: - L'intelligence des céphalopodes - La réionisation - L'effet Google - Ramanujan et les partitions - Y'a-t-il masse et masse ? - Energies renouvelables

6:59 PM | Letterpress cheating in Rust 0.11.0, part 1
It's been a while. I got busy with work and other things and have not revisited my collection of Rust toys recently. In fact, I skipped Rust 0.10 entirely. (It gets worse: I have about 2/3 of a Letterpress cheating program written in the dependently-typed ATS 1 language that I have not touched in months. I feel bad.) But I am turning over a new leaf. Or flake of rust, as the case may be. I am going to revisit the programs for Rust 0.11 before 0.12 comes out. I hope. In any case, instead of […]

1:41 AM | Church Youth Groups and Apologetics
Over on Facebook, Nancy Pearcey responded to a post about young people and deconversion from churches with a modest proposal: let them read apologetics. Age at which people leave the church — Tell me again why youth groups focus on games and goodies instead of majoring on apologetics? One study found that the age at […]

5:00 AM | Understanding Random Forests: From Theory to Practice - implementation -
Gilles Louppe just made available his thesis on Random Forests, it is entitled: Understanding Random Forests: From Theory to Practice Data analysis and machine learning have become an integrative part of the modern scientific methodology, offering automated procedures for the prediction of a phenomenon based on past observations, unraveling underlying patterns in data and providing insights about the problem. Yet, caution should avoid using machine learning as a black-box tool, but rather […]

4:30 PM | How To Cite Nuit Blanche and related pages
Since blogging and technical reference pages are somehow new to the scientific discourse, one sometimes wonders how Nuit Blanche and related pages should be cited. There used to be a way to say "Private conversation" or something similar, but following these guidelines here how it probably should be done in order to be consistent: * For a blog post that is entirely written by me please use the following for, say, a blog entry written on May 16, 2008:Carron I.

3:30 PM | 1250 posts on the CompressiveSensing Subreddit.
Since the first post on that CompressiveSensing subreddit, there has been more than 1250 posts there. You may consider joining and have conversations and ask questions there. One of the nice things about the overlay is that you can quickly watch the titles of the blog entries or other information thanks to the title and an image. Think of it as a table of content on what is new in compressivesensing and related fields. It's here: http://www.reddit.com/r/CompressiveSensing/  Join the […]

10:51 AM | How Turing accidentally invented the computer
It’s hard to do anything these days without a computer being involved in some way. From credit card readers to traffic signals to the phone in your pocket, computers can perform all kinds of tasks thanks to different software programs. So how did the programmable computer come about? In this animation, we show you how…Read more →

My comment below:Speckle suppression via sparse representation for wide-field imaging through turbid media by Hwanchol Jang, Changhyeong Yoon, Euiheon Chung, Wonshik Choi, and Heung-No LeeSpeckle suppression is one of the most important tasks in the image transmission through turbid media. Insufficient speckle suppression requires an additional procedure such as temporal ensemble averaging over multiple exposures. In this paper, we consider the image recovery process based on the so-called […]

1:05 AM | Constructive Sets
An approach to complexity lower bounds? Book source Kurt Gödel did it all, succinctly. His famous 1938 paper “The Consistency of the Axiom of Choice and of the Generalized Continuum-Hypothesis” was pages long. Since the Proceedings of the National Academy of Sciences was printed on single-column pages in fairy large type, it would have been […]

4:59 PM | Being a child of Moore's Law
Food for thought for the day.About two years ago, I wrote about predicting the future from the perspective of thinking linearly on an exponential slope (Predicting the Future: The Steamrollers, Predicting the Future: Randomness and Parsimony ). Here are three images I found on my Twitter feed that illustrate this. Recall that Genomic sequencing is going faster than Moore's law ( A Second Inflection Point in Genome Sequencing ? and then ...). The screen of what we initially called a […]

4:30 PM | The smallest phone charger ever…
If you are anything like me then inevitably pretty much every time you are about to head out you check your phone and there is no charge in it. It’s a really common problem.  Even worse you are already out an you’ve just found that it’s low on charge and will run out before you […]

1:00 PM | Postal/ZIP codes cartography: mapping the administrative organization
Postal codes numbering is an excercise that all states conduct differently. Some go from one end of the country to another. Some previously cut the country into regions. Others start numbering cities and then take into account the less urbanized areas, etc … This post provides a set of maps of postal codes in the world, according to the same principle: the low numbers are colored in red and the high […] The post Postal/ZIP codes cartography: mapping the administrative […]

5:00 AM | Phase Retrieval via Wirtinger Flow: Theory and Algorithms - implementation -
Phase Retrieval via Wirtinger Flow: Theory and Algorithms by Emmanuel Candes, Xiaodong Li, Mahdi SoltanolkotabiWe study the problem of recovering the phase from magnitude measurements; specifically, we wish to reconstruct a complex-valued signal x of C^n about which we have phaseless samples of the form y_r = |< a_r,x >|^2, r = 1,2,...,m (knowledge of the phase of these samples would yield a linear system). This paper develops a non-convex formulation of the phase retrieval […]

8:26 PM | Android Auto vs. iOS CarPlay: How Your Car Will Get Smarter
Google's announcement of Android Auto at the recent Google I/O conference should surprise exactly no one. Apple is gearing up for its own in-car infotainment service later this year called CarPlay. It's long past the time when Google would hang back and see how Apple's approach to a new market worked out -- Android Auto is going head-to-head with CarPlay later this year.Both companies want their mobile platform with you all the time, but how are they going to convince people to embrace […]

8:00 PM | Brick-A-Pic Kickstarter Project Creates LEGO Mosaics
When I visited LEGO Master Builder Nathan Sawaya's art gallery in New York last September, I asked the brick artist about how he designs and constructs his beautiful LEGO mosaic renditions of iconic and classic paintings. Sawaya told me that he creates those 2D LEGO paintings all by sight and hand--choosing the individual brick colors one at a time to adapt the original piece of art. Not all of us have that skill, so a new Kickstarter is attempting to automate that design process using clever […]

7:12 PM | Does a lack of affiliation mean I cannot publish ?
I am not affiliated with Texas A&M University any more. It shouldn't matter, except it does. My profile can not appear on Google Scholar search since I don't have a verified e-mail, i.e an email address ending with '.edu'.Let us not even talk about the fact that a blog does not constitute a publication. Here is another example: when I tried to figure out the exact affiliation I should probably have been listed in the last paper, here is what I received: Dear Igor […]
