8:53 PM | Video (in French): Making Sense of IoT Data ( Paris IoT#5 Meetup )
Last week, I gave a presentation on Making Sense of Internet of Things (IoT) data, here is below the slide I added after the talk. This new slide makes it clear that the sharing is central for IoT to become more than just a collection of useful gadgets. The story goes that one Geiger counter is nice to have, but a collection of them maps radiation fields; kilopixel cameras were certainly nice to have, but 10s Mpixels now provide cameras with information that can be used for other purposes such […]

12:39 PM | Resource: The COMPARTMENTS database on protein subcellular localization
Together with collaborators in the groups of Seán O’Donoghue and Reinhard Schneider, my group has recently launched a new web-accessible database named COMPARTMENTS. COMPARTMENTS unifies subcellular localization evidence from many sources by mapping all proteins and compartments to their STRING identifiers and Gene Ontology terms, respectively. We import curated annotations from UniProtKB and model organism […]

On Rabin’s recent talks at Tech Jeffrey Shallit is a computational number theorist, with many wonderful results. He is also well known for his work as an advocate for civil liberties on the Internet, and also against intelligent design (ID). Indeed he was at one point slated to testify in the 2005 Dover case until […]

11:57 PM | This review of Max Tegmark’s book also occurs infinitely often in the decimal expansion of π
Two months ago, commenter rrtucci asked me what I thought about Max Tegmark and his “Mathematical Universe Hypothesis”: the idea, which Tegmark defends in his recent book Our Mathematical Universe, that physical and mathematical existence are the same thing, and that what we call “the physical world” is simply one more mathematical structure, alongside the […]

5:48 AM | Poly-publications on the polypharmacology of kinase/bromodomains dual inhibitors
When you consider how vast the chemical space is and how restricted the topology and chemical environment of a specific pocket in a protein is, it's quite surprising we can find molecules that the protein was not evolved to bind that can nonetheless bind and inhibit it potently. It is therefore even more surprising when a single molecule can potently hit two completely unrelated (by sequence, by structure and by function) proteins. Thus, when two independent groups publish such dual […]

7:22 PM | Testing Maxwell: Nvidia's Six-Inch Hammer
Nvidia recently unleashed its latest graphics architecture on the world, Maxwell. The first iteration is the GTX 750, a GPU that will be the core of a graphics card whose asking price will typically be under $150. Two variants of the GTX 750 will be shipping, the GTX 750 and the GTX 750 Ti. I’ll get into the differences shortly.Once upon a time, the first iteration of a GPU architecture would show up as powerful, power-hungry beasts of a graphics card. That changed a bit when Nvidia […]

5:30 PM | Star Wars and the Explosion of Dolby Stereo
When Star Wars came out on May 25, 1977, the cinema experience was changed forever. While some critics feel that Star Wars changed movies for worse by contributing to the modern blockbuster syndrome, there’s no doubt that for technology and special effects Star Wars was a huge leap forward. In particular, the way Star Wars cemented Dolby Stereo’s dominance in sound transformed the way we would listen to movies in theaters and at home.Sean Durkin, the director of corporate […]

4:00 PM | In Brief: Voicemails Are The New Texts
Here's something I never thought I'd say: my computer-illiterate parents taught me something insightful about technology culture. I got both my parents iPhones this past holiday. It's their first smartphone and I wanted them to use a device with a familiar and relatively unbreakable interface and operating system (they previously shared an iPad). But I soon realized that the only thing weirder than my parents using Facebook on their phones was them texting me. Communicating with them over text […]
