I think so but it doesn’t really matter. It’s far faster to apply at the border anyway.

This is not remotely true. The gap between them as players far exceeds the gap elsewhere, combined, many times over.

On one of these less forgiving architectures, how does one write programs that read some bytes off the network, bitcast them into a struct, and do something based on that?

On x86 you would use a packed struct that matches the wire protocol.

Wouldn’t this require extra copying if member reads were forced to be aligned?

Quite the opposite actually. Simons and similar practitioners eschewed fundamental valuation techniques. Buffett is possibly a better example.

To add, the set of observable mutations (beneficial or not) that occur as a result of a single point mutation is in all likelihood an extremely tiny subset of the set of all observable mutations - even after “deduping” for the observed effect.

It’s an intentionally misleading tweet.

To simplify, It’s saying, if the genome were a string of some length, for any possible byte b and byte position i, there exists a person whose genome has b at position i. Unlike normal character strings, there are only 20 or so valid characters (proteins) encoded by 3 “bytes” (nucleotides) each. So you’re looking at O(10 billion) values of (i, b) that would still keep the string well-formed in its 3-bytes-per-character encoding.

Most importantly, it’s not saying anything about having some bytes b1 and b2 at the ith and jth positions or any generalization thereof.

Interesting - is there a type safe way to do this? vector>? and/or a custom “vector allocator” to hide the details?

> CMake doesn't fetch your dependencies for you and ensure they're the version that your code is compatible with.

That’s a little too harsh. You can certainly make it do that via a combination of git tags (to build from source) and CMake modules/Find*, but yes, it’s much more cumbersome than cargo/npm/go

Very cool! What tool did you use to simulate this? What does the code/query (if any) look like?

(Author here) Thanks for explaining this more succinctly than I can :)

Just one nitpick:

> decent amount of stuff that has to be done in main before you run _start

should read

> decent amount of stuff that has to be done in _start before you run main

Analogously, cleanup code like running global destructors usually happens in _start/CRT after main returns, but I skipped that in the post for the sake of brevity.

Interesting! I liked the configurability, but it was horribly slow with SSL. Possibly due to uncached DNS lookups but I didn’t dig too deep.

Good answer. OP didn’t specify “blew your mind in a good way”.

Typo in the first code snippet:

> model.get('get')

did you instead mean:

> model.get('age')
