2:39 PM | My Testing of the Samsung Galaxy S6 Smartphone
Editor's Note: Our Android expert Ryan Whitwam gives his take on the new Galaxy S6 smartphone. This review complements my own thoughts and testing on the phone, and we'll have a full In-Depth video on Tested next week!Samsung needed a change after the Galaxy S5's lackluster performance last year, and the Galaxy S6 is what the Korean company came up with. Many of the basic tenets of Android design from Samsung have been abandoned, and the build quality is worlds apart from the last five Galaxy […]

1:53 PM | Rotating PDF pages with Python
Yesterday I got a review copy of Automate the Boring Stuff with Python. It explains, among other things, how to manipulate PDFs from Python. This morning I needed to rotate some pages in a PDF, so I decided to try out the method in the book. The sample code uses PyPDF2. I’m using Conda for […]

12:58 PM | Net Neutrality and Irony Meter Implosion
In looking up commentary on net neutrality, I found Kool-Aid chugger Chris Harris. (I was actually looking for “Logan Albright”, and found Harris as an inveterate quoter of Albright.) Amidst a bunch of other hogwash, Harris makes a plea to consider the ISPs: Some dissenters against “Net Neutrality” are most concerned with the free-market implications […]

5:00 AM | Nuit Blanche in Review ( April 2015 )
NASA / JHUAPL / SwRIIn the past month, we witnessed the first images of Pluto with a resolution never attained before thanks to the New Horizon mission  and last night, we bid farewell to the Messenger spacecraft as it crashed on Mercury.Well I guess it is time to say goodbye to all my friends, family, support team. I will be making my final impact very soon.— MESSENGER (@MESSENGER2011) April 30, 2015 Since the last Nuit Blanche in Review ( March 2015 ), we had quite a few hardware […]

8:36 PM | Transcomputational Problems
Problems beyond brute force search Cropped from Wikipedia source Hans-Joachim Bremermann was a mathematician and biophysicist. He is famous for a limit on computation, Bremermann’s limit, which is the maximum computational speed of a self-contained system in the material universe. Today Ken and I wish to talk about the limit and why it is not […]

8:00 PM | In Brief: 200MP Scans of Interstellar IMAX Film Cells
Regardless of whether you thought Chris Nolan's Interstellar was a good movie or not, it was undeniably beautiful in its depiction of space and space travel. The recent Blu-Ray release of the film included a 70mm IMAX film cell with each copy, and buyers have begun sharing what cells they've received on Reddit and in AV forum threads. One awesome thing that's come out of it is users who've put their collectible IMAX cells under archival-grade optical scanners, like this Reddit user. His Nikon […]

6:47 PM | Task-driven Adaptive Sensing on Quadrupole Mass Filter Systems for Classification
David Brady the man behind compressive hyperspectral imaging is at it again with colleagues. He now investigates some hardware and adaptive sensing to perform some mass spectroscopic measurements. This is important as the next step after the whole genome sequencing adventure starts with understanding the proteins produced by the genome.  Task-driven Adaptive Sensing on Quadrupole Mass Filter Systems for Classification by Evan X.

6:20 AM | LaTeX, Word, ggplot, and n00b-ness
I've been forcing myself to learn enough R and ggplot to make nice looking plots. It's taking me painfully long to learn to do even the most basic things, and +Carlos Scheidegger has been a big help !What makes learning ggplot hard is grasping its underlying design philosophy. There's a notion of layers in a plot that I'm still getting used to. Once you get the hang of it it's quite elegant, and makes modifying plots very easy -- once you get the hang of it.All of which makes me a […]

5:00 AM | Finding a sparse vector in a subspace: Linear sparsity using alternating directions - implementation -
Here is another of Ju's implementation from an earlier paper: Finding a sparse vector in a subspace: Linear sparsity using alternating directions by Qing Qu, Ju Sun, John WrightWe consider the problem of recovering the sparsest vector in a subspace S⊆Rp with dim(S)=n<p. This problem can be considered a homogeneous variant of the sparse recovery problem, and finds applications in sparse dictionary learning, sparse PCA, and other problems in signal processing and machine learning.

9:39 PM | The Best SSDs Today
This post was done in partnership with The Wirecutter, a list of the best technology to buy.Read the original full article below atTheWirecutter.comIf I were buying an SSD to replace a mechanical hard drive or an SSD that's running out of room, I'd get the 500GB Samsung 850 EVO. It has one of the best combinations of price, performance, and capacity of any drive you can get, plus easy-to-use software and a long warranty, and it comes from a company that makes excellent SSDs (and all their […]

8:36 PM | Testing: Lowepro Fastpack BP 250 AW II
For the past two years, I've been using an Incase DSLR Pro pack not just as my camera bag, but as my everyday backpack for work and travel. I loved it because it had enough capacity for all my mobile office equipment (laptop, chargers, peripherals), DSLR, multiple lenses, and even space for a second compact or mirrorless camera. The way the bulk of the pack is divided allowed me to dedicate a lot of space for camera gear, but with plenty left to drop in other equipment between the velcro […]

3:55 PM | How to Get into Hobby RC: Comfort Mod for FPV Goggles
I've worn several different brands and models of FPV goggles. While some may be slightly better than others, I've yet to find any goggles that I thought were particularly comfortable. I tend to devote a good bit of time prior to every FPV flight fidgeting with my goggles to get them positioned just right. Their poor fit was something that I tolerated for the thrill of flying FPV. Recently, I decided to take a more proactive approach to the problem.A popular modification for FPV goggles is to […]

3:30 PM | Complete Dictionary Recovery over the Sphere - implementation -
Ju just sent me the following: Dear Igor, Would you help mention our new paper on dictionary learning in your blog? http://arxiv.org/abs/1504.06785We show one can recover complete dictionaries with efficient algorithms when the coefficient matrix has up to linear sparsity (under suitable probability model). Our earlier work http://arxiv.org/abs/1412.4659is also relevant, in the sense in both papers the core technical problem we try to tackle is how to retrieve the sparest vector(s) (directions) […]
