I know AWS in particular does not because they do not increment the bill for every request. I don't know exactly how they calculate billing, but based on what I do know about it, I imagine it as a MapReduce job that runs on Lambda logs

The algorithm for BB(N) is (with some hand waving) “for each N-state Turing machine, check if it halts on an initially empty tape. If it does not, skip it. If it does, run it until it halts and count the number of steps, k. BB(N) is the max

CS is sort of unique in that regard. I value my university degree, but when I think about the classes that helped me the most, only one of them was a degree requirement. Not because the degree was useless, but because the information was ac

A Markov process is any process where if you have perfect information on the current state, you cannot gain more information about the next state by looking at any previous state. Physics models of closed systems moving under classical mech

I thought that the point of replaceState was precisely to avoid appending elements to the history, and instead replace the most recent one, so I think I must be missing something if that line causes lots of additional history items.

The main “why” that I find is that it allows you to intentionally design your API types and know when a change is touching them. I worked on a project with a codebase on the order of millions of lines, and many times a response was made by

I really wish policing would take more inspiration from aviation on a different avenue for police accountability. The NTSB exists not to blame pilots (though they sometimes do), but to make air travel safer and prevent future plane crashes.

If you specify your constraints in pyproject.toml like this: `package1==0.4.0`; then that is the latest (and only) version satisfying your constraints. Not upgrading is expected behavior, because upgrading would violate constraints. pypro

I notice that library self-identifies a problem of generally keeping a fixed-size number of buckets and addressing them with hashing, which leads to great memory usage but introduces a risk of collision. Stochastic Fair Blue shares that pro

Hmm, that's a good point, since the bloom filter check is CPU-harder than the action taken on lookup, you could just do all the lookups in parallel and then do all of the copies separately.

by hxtk 1y ago
I'm confused by this line here: https://github.com/ross39/new_bloom_filter_repo/blob/4798d90... It seems like this would make the compression lossy and discard, e.g., transitions from #ffffff to #fffffa,

by hxtk 1y ago
The bloom filter lookups here are fundamentally not parallel because they are coupled to a serial iteration. Ultimately the data they are storing is tuples of (x,y,r,g,b), which means that it is not sufficient to ask "does (x1,y1) pas

From what I can tell, it also isn't lossless: https://github.com/ross39/new_bloom_filter_repo/blob/main/vi... This looks like it is not storing the diff for any pixel that had the mean of its r,g,b

by hxtk 1y ago
It sounds like your instinct here is that we need to store (x,y,r,g,b) tuples for everything that changed, and leave other pixels unchanged from the previous frame. You could store all of that in a single map from (x,y) to (r,g,b), which wo
