3:47 PM | On shellshock
The 'net is currently focused on Shellshock, leading to interesting discussions of the responsibility for the problem. Recently, someone posted Not a bash bug, which was linked on Hacker News. The argument there is that: I would argue that the bash security concern is not a bug. It is clearly a feature. Admittedly, a misguided and misimplemented feature, but still a feature.... It is an old precept for security on unix systems, that environment variables shall be controlled by the parent […]

1:26 PM | Compressive Earth Observatory: An Insight from AIRS/AMSU Retrievals (and a comment)
This is exciting but I have included my thoughts below: Compressive Earth Observatory: An Insight from AIRS/AMSU Retrievals by Ardeshir Mohammad Ebtehaj, Efi Foufoula-Georgiou, Gilad Lerman, Rafael Luis Bras We demonstrate that the global fields of temperature, humidity and geopotential heights admit a nearly sparse representation in the wavelet domain, offering a viable path forward to explore new paradigms of sparsity-promoting assimilation and compressive retrieval of spaceborne earth […]

7:52 PM | The great reformulation of algebraic geometry
“Tate helped shape the great reformulation of arithmetic and geometry which has taken place since the 1950′s.” — Andrew Wiles At the Heidelberg Laureate Forum I has a chance to interview John Tate. In his remarks below, Tate briefly comments on his early work on number theory and cohomology. Most of the post consists of […]

3:07 PM | [Visualisation] 1914-1919: L’étonnant itinéraire d’un Suisse au service de la France
1er août 1914: Les nouvelles politiques étant fort mauvaises, j’ai quitté Genève à 2 heures 28, ayant fait mes adieux à ma bien-aimée Hélène sur le quai de la gare… Les premières lignes du “Journal de la Guerre” de l’écrivain suisse Guy de Pourtalès rappellent le ton de certains écrits de poilus. Mais bien que décrivant le même conflit et s’inscrivant dans […]

2:15 PM | Mental crypto footnotes
I spoke with Manuel Blum this afternoon about his password scheme described here. This post is a few footnotes based on that conversation. When I mentioned that some people had reacted to the original post saying the scheme was too hard, Blum said that he has taught the scheme to a couple children, 6 and […]

12:37 PM | Alternating proximal gradient method for sparse nonnegative Tucker decomposition - implementation -
Alternating proximal gradient method for sparse nonnegative Tucker decomposition by Yangyang XuMulti-way data arises in many applications such as electroencephalography (EEG) classification, face recognition, text mining and hyperspectral data analysis. Tensor decomposition has been commonly used to find the hidden factors and elicit the intrinsic structures of the multi-way data. This paper considers sparse nonnegative Tucker decomposition (NTD), which is to decompose a given tensor into the […]

2:47 AM | My 10 Virtual Reality Takeaways from Oculus Connect
I've had a few days now to digest all the information that came out of this past weekend's Oculus Connect conference. It may have only been a two-day developer conference, but the keynotes alone had enough information to expand the imaginations (and lexicon) of virtual reality enthusiasts. There was of course the big Crescent Bay prototype announcement and demo, which Oculus unfortunately said that it has no plans to release or show anywhere else. It was also my first time being able to try the […]

12:05 PM | Proof maintenance
Leslie Lamport coined the phrase “proof maintenance” to describe the process of producing variations of a proof over time. It’s well known that software needs to be maintained; most of the work on a program occurs after it is “finished.” Proof maintenance is common as well, but it is usually very informal. Proofs of any […]

7:33 AM | Testing: Blade 350 QX2 AP Combo Quadcopter Review
I’ve been flying an original DJI Phantom quadrotor for almost two years. Even though it’s never given me an ounce of trouble, watching the super-stable video footage from quads equipped with camera gimbals convinced me that I needed an upgrade. Rather than add a gimbal to my Phantom, I decided to keep it as a sport flyer and add a new quad to my fleet. The new ship is a Blade 350QX2 AP Combo (~$900). Its features are similar to the Phantom 2 Vision + reviewed by Norm and Will, but […]
