This is really cool. Have you looked at all at the constant Q transform https://en.m.wikipedia.org/wiki/Constant-Q_transform which is basically a Fourier Transform with logarithmically spaces bins so that it can be al

Well according to Cuomo’s March 26 briefing the ventilator situation maybe nearly that bad. https://www.bloomberg.com/news/articles/2020-03-26/n-y-death... 3-4 days for non-covid versus 11-21 days for covid.

Yeah I think this terminology is odd because I think that the computable numbers are much more “useful” than the definable numbers.

The test they use to select employees correlates with their rating of employees is pretty circular. Any arbitrary test will do that.

I haven’t read this in detail, but a few things stand out. In the write up, you say it compares better than bitwise radix sort. You need to compare against an optimized byte-wise radix sort which is by far the fastest sort for decent size

Somewhat, in that it doesn’t use more precision than needed, but the real issue is you can’t just pick some arbitrarily large precision and round at the end. For some calculations, even 400 digits during intermediate steps would not be enou

The default Android calculator app by Hans Boehm (developer of the Boehm Garbage Collector as well) does this by using the computable real numbers. https://dl.acm.org/doi/10.1145/2911981 Provides a good overview o

This isn’t a performance optimization but rather an accuracy optimization. Even if the requested output is a double (64-bits) the intermediate calculations often need to be done to higher precision to get fully accurate answers. Note that

I would also like to not that encoding the the Option<char> using the unused bits of the return value is a perfectly valid implementation. But that is exactly what it is, an implementation detail. It could work exactly the same way as

Actually this is quite a bit different. This is more a columnar-store version of SQLite, basically an embedded OLAP database, which is pretty cool. I’m not aware of other column-stores in this niche, most are distributed systems meant for

NULL is similar to floating point NaN (aka not a number) which also has the same comparison operation NaN != NaN.

It’s downside is that it is computationally very expensive. All of the other NIST candidates are not very computationally demanding, but have much larger keys. So the trade off with SIDH is that it spends a lot of time calculating while th

Weird that this is being downvoted because Uber has shown no interest in acquiring and managing assets (self-driving cars or even their own cars) which is a completely different business than being a marketer for independent taxis. If self

In most cases k << n. For 64-bit integers, byte wise radix sort k is 8, which is less than log n whenever n is more than 256. So, radix sort is typically much faster than an O(n log n) sort of your data support it. It just isn’t as
