I like Jonathan Blow and all, but he should be careful with trashing academic parsing theory if he thinks that Pratt parsing was only discovered "in the last few years".

One interesting aspect of this is that they still explicitly expect "synchronous" work, timezones be damned: > We have initially designated 9am to 3pm Pacific Time as “coordination hours” where most employees will be expected t

One thing the author doesn't discuss is that the Boom objects themselves are also in memory, and also have to be accessed -- and can therefore also be visited not in memory order, and cause cache misses. Changing this to a "struct

Escaping isn't an intrinsic property of all quoted strings (e.g. single quoted strings in bash), but even so one can work around them without backreferences, by searching for anything that's not a quote or a backslash, _or_ any es

"Uporządkować" can be "sort out" too, though I'd more often translate it as "tidy up"; "zająć się czymś" is roughly "take care of something", maybe you could use "occupy yourself w

"Sort out" is a pretty solid translation IMO

There's also a _great_ talk from the creator (Sam Aaron) on Sonic Pi, including live-coding examples and some wonderful insights on how computer science is taught in schools: https://www.youtube.com/watch?v=OLLwG_SN8oo

V8 has a hand rolled JSON parser which feeds directly into our object model without any intermediate data structures. This allows us to take advantage of structural knowledge, e.g. we assume that objects in an array have the same shape (and

Is uncompression a derivation?

It's actually very relevant, the TL;DR (from memory) is that lawyers (and judges) aren't programmers, and the source of data (referred to as the "colour of the bits") is as important as the actual bits of the data. Thus

Well, JavaScript Map preserves insertion order when iterating entries, and as of ES2015 (i.e. ES6), for-in also iterates the (string, non-numeric) properties of an object in insertion order.

Yeah, sorry about that, it's fixed now.

There's likely an interesting Ship of Theseus debate to be had about whether these are indeed thousand-year-old windmills, and whether it's accurate to consider the windmills build a thousand years ago to be "still standing&q

Bytecode aging actually existed already for other reasons (expiring code caches).

I had thought that, as long as the object in that location is valid (e.g. constructed with placement new and not since destructed, with the `char ` as a pointer to the storage), then accessing it through the `char ` is valid -- but maybe th

You'd think so, but in fact reinterpret_cast from char* (and unsigned char , and std::byte ) is explicitly allowed by the type aliasing rules.

Though to be fair, full source strings are kept around in memory for lazy compilation anyway (and other lazy computation).

Yeah, for someone not used to the code it's tough. The "insider knowledge" is that builtins defined in .tq files (files compiled by the Torque compiler[0]) are added to entries in the Builtins enum, which itself is defined as

Germany has similar workers' rights and protection from firing, yet it has a lower unemployment rate.

Thank you for mentioning micro- vs macro-readability, I feel that too often people concentrate on the former without considering the latter.
