I never understood why MotionDSP ( http://www.motiondsp.com/products/ ) never marketed to consumers or consumer applications, and pigeonholed themselves as a law-enforcement- or intelligence-only product. Granted, I'm sure there's plenty

Memory capacity is typically dedicated (e.g., Linode), but memory bandwidth is difficult to allocate statically, and can be a huge problem even if you're fine on capacity. For example, a simulator I like to run has a 50-60MB working set, m

My take is that mathematics provides rigorously defined, leak-proof primitives and operations. Most of the difficulty involved in porting a piece of math to a program is in plugging the leaks in the abstractions provided by efficient machi

Can someone familiar with Matplotlib comment on how Sho's Python plotting utilities[1] compare? This looks cool; still trying to wrap my head around what's fundamentally new vs. what is packaging together existing Python libraries and letti

Python's standard library includes a lot of functionality that only really makes sense on top of an operating system, e.g., filesystem operations, inter-process communication. By the time you implement that kind of thing, plus drivers to c

Might improve user experience a bit, but your password hashing scheme needs to take much longer if an attacker knows he can rule out lower-case letters. For example, 8-character alphanumeric passwords: ((26*2)+10)^8 / (26+10)^8 = 77.4 You h

My interpretation of the "yield" keyword is not that of a coroutine yield, but that of "cough up the following value", which is more in line with "return". Under that interpretation, the fact that generators can also be used to implement

For CPUs, you need to at least allow programming at a much lower level because of the greater diversity of workloads. The average programmer will never write anything that cannot be specified in C, but they will certainly use such code

You're right that giving the OpenGL runtime information piecemeal (one vertex at a time, repeated every frame) is no longer acceptable for many apps in terms of performance, but I'd argue that that's not a strike against the abstraction lay

3D graphics is also my favorite success story for programming abstractions. This code: glColor3f(1.0, 0.0, 0.0); glBegin(GL_TRIANGLES); glVertex3f (-1.0, -1.0, 0.0); glVertex3f (1.0, -1.0, 0.0); glVertex3f (0.0, 1.0, 0.0)

Rasterization is slow when you have lots of small (often sub-pixel) triangles. Mapping a big triangle into screen space is fast, but mapping many triangles per pixel (and hopefully throwing out the 99+% of the geometry that won't show up a

Nothing. In fact, everyone does this at least to first order; you need to do bundles of primary rays at a time to take advantage of their spatial (and thus, memory access pattern) coherence. The problem is that the secondary rays are not

You're right, an inflation-adjusted dollar should buy some fixed fraction of e.g. a loaf of bread at any time in history. It's just such a multidimensional space that any one number is bound to leave out some pretty crucial information as

This is a good point. Really good ideas can overcome legislative and regulatory inertia, with enough money and time behind them, thank goodness. My only devil's advocate point would be that drive-by-wire cars typically have mechanical fail
