Not quite free. Last I checked, adding automatic differentiation to GPU computation for pricing exotic derivatives roughly doubled the computation cost. (Though, traditional bump-and-reprice has exponential cost in the number of dimension

I spent 11+ years at Goldman, working in SecDb Core, and various SecDb-related infrastructure. Goldman's Slang language has subsets of both lazily-evaluated backward-propagating dataflow graph ("The SecDb Graph") and forward-

I believe Pharo evolved from Squeak SmallTalk. I'm not sure if they started calling it a new language because of the number of extensions on top of SmallTalk-80 or if they introduced any breaking changes from SmallTalk-80, or if they

And later, the Antonine wall a bit further north. Though, it's probably more accurate to say the walls were built to reduce the costs of Pictish raids. I doubt the governor in Londinium woke in a cold sweat fearing Pictish invasion,

It's not so weird. My understanding is that genes migrating across chromosomes (translocation) isn't that common. So, to a first approximation, genes are inherited as 46 indivisible units. Every generation, a given chromosome h

For one, England means "land of the Angles" (or in French, "Angleterre": "Angle land"). The Anglo-Saxon majority people group of England descend from the Angles, Saxons, and Jutes, from the coastal German regi

I'm really interested in this space. I'm the original author of the Wikipedia page on SafeTSA. I really want compiling to native code to be as common as writing inline assembly currently is (and I see no fundamental reason why i

Bounds checks are either runtime checks or removed by static analysis. JIT just pushes back the time at which that static analysis is done and increases the amount of context available (largely through inlining). It's still fundamenta

The JVM can elide most of the Java bounds checks because it has much more static information from Java class files than is available from C code. Once you're emulating a memory-unsafe language, you lose most of those static semantic g

Yes, the language runtime version of the "Turing tarpit". Any Turing-complete system can emulate any other. However, in this case, you're bounds-checking absolutely every memory operation, whereas with native Java field ac

C++ and Java reference semantics are very different. Java, like Python, has a model of "references passed by value". void caller() { T a = new T(0); T b = new T(1); callee(a, b); } void callee(T a, T b) {

The variable-sized word made more sense when writing code to work acoss machines with 16-bit and 18-bit words or 32-bit and 36-bit words. This is also why you get C99's uint_least32_t and friends, so you're not accidentally forci

Either I'm misunderstanding you, or you're misunderstanding the GP. The GP is getting at large language models being equivalent to very high order Markov models combined with calculating argmax over all possible outputs.

I strongly suspect the issues you're referring to are much more an issue with attitude and mindset, rather than directly with education. I think there are probably much more efficient ways to adjust attitude and mindset than broad-bas

That would require a re-formulation of conservation of color charge. You could probably come up with an alternative formulation where everything is consistent, but all of the formulas would almost certainly be more complicated. The most o

I vaguely remember reading about some similar experiments with goggles that mirrored vision. As I remember, after a few days, people can mostly overcome the difficulties of having their vision reversed.
