   I can write anything to do any computation in any programming language. The whole point is that there are pre-existing, high quality libraries and toolboxes to do these operations. In fact, that is exactly why R is popular - it has excellen

   I think your perspective is too small. R is a DSL for data and statistics. Matlab is used in academia and industry across all engineering disciplines, where data and statistics is but a small subset of its total capabilities. You will never

   Libraries. Inertia. The IDE is actually far more polished than Spyder. It makes things easier for non-programmers with many wizards, and excellent help files. The toolboxes are uniformly fairly high quality. I should mention again the help

   If it isn't based on the Navier Stokes equations, can I actually use this to reliably simulate fluid behavior? Or is this more useful for creating pseudo-realistic water scenes?

   Still, the Hilbert transform is fundamental knowledge. Although it may not be particularly suited for analyzing speech, it is crucial for understanding communications theory. It's a good next step in the study of envelopes.

   Latex has too much inertia for users to switch anytime soon. The only competition is from commercial tools like Adobe Framemaker. I hope the future will turn out to be Lyx + Asciidoctor export. If Microsoft Word ever improves their math inp

   In your view, are gold and other precious metals commodities or money? If your answer is commodities, why not money?

    I don't understand what you mean about lacking math support. I am writing math exercises using asciidoctor right now, as it integrates with Mathjax. I would highly recommend asciidoc over markdown for scholarly work in succint plain te

    Lead acid is traditionally very forgiving with regards to temperature. How does the electrical performance of your battery vary with temperature, especially at extremely cold (-40C) and extremely hot (80C) conditions?

    If you are a web developer, you might try WebGL? Same ideas, different packaging focused on graphics. Once you get the hang of it, you've got the language paradigm to understand CUDA, OpenCL, etc. If you write business software... I&#x

    I don't know much about CUDA, just what I see from my co-workers who do get to use it. The Visual Studio integration looks amazing. The C++ api is cleaner. I am told there are lots of little quality-of-life API things that are better f

    Any problem where you have large vectors or matrices of floats and must add, subtract, divide, or multiply on them in parallel for performance reasons. A GPU is like a miniature datacenter in your computer! But, unlike a real datacenter, it

    CUDA has been on my list of things to learn for quite some time. The ecosystem is just so much nicer than OpenCL... if I didn't have to support non-Nvidia GPUs, I'd have already gotten on the bandwagon.

    I watched the talk, not having a lot of exposure to functional programming, but having exposure to C++ through my job. I am still not sure I understand his presentation. The beginning was straightforward and had some good takeaways. The mes

    Oscilloscope #2 is $269 and has a 60 MHz bandwidth. How on earth is that good value? I would like to recommend the Rigol DS1052E in that price range, or a used HP/Tektronix analog scope for the sub-$100 market.

    I like VHDL. Verilog and non-blocking vs blocking assignments can trip you up so easily. As for verbose code, you spend way more time debugging and thinking about how to structure a program than you do writing text on the screen.

    I'd be interested in reading about real world experience with Intel TBB, and comparisons to Fastflow, which seems to be the nearest competitor.

    Huh. I'm interested in playing around with this, but the free developer account requires you to use pre-qualified hardware. In my case, I already have a designed device. Why don't they expose an API?

    At run time - the language has built in support for assertions (syntax and conciseness way more convenient than C++ et al), contracts pre and post-condition, and you can run a formal logic analyzer on it if you limit yourself to the Spark A

    How does Protobuf compare with Corba? I'd be interested in anybody's experience if they have used both.

    I'm surprised that they developed a brand new time tracking tool. From my limited experience, it seems Deltek Time & Expense is the most popular time tracking application in the government / associated contractor space.

    I don't know if "For Dummies" is possible for building a GPS system from first principles. If you want to really learn by building, I recommend "Fundamentals of GPS Receivers: A Hardware Approach" by Dan Doberstein,

    I've worked in embedded devices, and the problem isn't that the engineers don't know how to fix it properly, it's just that nobody cares enough to make consumer-level devices very secure. That costs money.

    Smaller, lower power computers are great. But the problem is, and remains, the power consumption of the RF channel. It's all well and good that your processor consumes microamps, but one second of WiFi traffic at a reasonable transmit
