Ah, this is definitely possible as well; you could statically analyze the function and then topologically sort the recursive calls. But that falls into an optimization category which requires some sophisticated analysis. That type of optimi

Yeah, debugging the written function is not easy, but that could be improved by adding the normal tools for rewrites (sourcemap). Also, you can put print/logging statements inside the function; the rewrite preserves those. In theory th

Hi HN, I wrote this. Admittedly Fiber is not the best name — in the current implementation we don't yield to the scheduler except for recursive function calls, and our "scheduler" only runs a function to completion. These thi

My point is your analogy is not comparable, not that OP is acting morally or not morally. When a company issues dividends, it voluntarily (consensually) gives to those who have provided it value. When you steal from other fisherman and call

It depends on the harm done. Obviously if you’re playing with your friends there is likely no harm done. If you’re wasting 50+ other people’s time (e.g. FPS battle arenas) then you might want a harsher punishment. Of course there are degree

Of course you're right in cases of a cold start. But if I understand the benchmark in the linked post correctly, the TTFB was measured assuming that the VM was already hot & and the code optimized through TurboFan already. (Hence &

Assuming that we're using V8 and the function is hot, both the JS code and the WASM will be compiled to optimized bytecode by V8's TurboFan optimizing compiler. The two big reasons why JS is inefficient vs Rust+WASM is because (1)

Tarjan's proof of inverse* Ackermann bound is hard to understand; it's much easier to understand the proof of the log*(n) bound, which is also an extremely slow growing function: https://people.eecs.berkeley.edu/~v

Nit: when you say better you mean "more economically efficient in terms of $s produced." That's not necessarily equivalent to a policy that would be the best for society.

As someone who went to Exeter and did higher-level math there, you didn't have to even start calculus in order to graduate. Also, the calculus taught there is roughly the same level as a decent public school. And you can probably get t

But then your definition of leak is arbitrary, because who's to say that memory won't be re-accessed in the future? You're right that that problem is equivalent to the halting problem.

I don't know if Valgrind (or Clang msan) would catch this bug as it might not be associated with any calls to *alloc/mmap/free/etc. Seems like a kernel issue, and I don't know if Valgrind has the capability to peer

It's not equivalent; you can tag every pointer with a special bit. Then statically you know the accessible roots at every instruction pointer value, and you can simply traverse accessible memory regions, following tagged pointers. Free

By DP state, I mean the arguments to the recursive function (for U, the state is the tuple (i, j)). For example, if you wanted to use DP to compute all-pairs-shortest-paths (Floyd-Warshall), you add a third parameter to the DP state ((f(u,

It might be easier to define f(m, n, v) where f(m, n, v) is the number of v-vertex shapes that can fit within a m-n square with exactly one vertex in the top left hand corner. Then Q(m, n) = \sum_{i \in m, j \in n} f(m, n, 4). f also lends

I would also like nominal types in TypeScript, but one issue is that it might open a can of worms that is antithetical to one of TypeScript’s main design goals: that a change in the typing of a program should not be able to modify behavior.
