Interesting points. > Implementing generics in this way breaks parametricity. Simply put, parametricity means being able to reason about functions just from their type signature. You can't do this when the function can do arbitrary

Side note: “write everything twice” (WET) is originally meant as a reaction to DRY (“don’t repeat yourself”). I think the author uses the credo here for something else (which is still good advice).

Why does “I contend” feel awkward to you? It is more specific than “I differ” because that could also mean that the author physically differs, which is awkward, while “contend” is specifically used for disagreement on some topic? Does “I co

I believe “database independence” is an anti-pattern in 99% of the cases. Abybody with me? I’ve had great success by not using a database abstraction layer: - you can invest the time you spend on being a generalist on many databases to be a

Coroutines are just multiple call stacks. If coroutine A calls coroutine B then B excutes on its on stack and can ‘yield’ a value back to A. Yielding is just a return across stacks without destroying the current stack. So A continued with t

Yes, there is a generation number in the reference. It is checked against the generation number of the allocation that is stored in the allocation: void __check(GenerationalReference genRef) { uint64_t currentGeneration = *(uint64_t

Yes, I am wondering too. How would it even stop use-after-free and double-free? The "check" function accesses the allocation because it needs the generation number of the allocation. So basically, the reference needs to access the

Because of Price’s law: the square root of number of employees do about 50% of the work (that creates value). So 10.000 emmployees means 100 persons do 50% and 9900 the other 50%. This mean that a team of 4 is the most efficient size. Howev

What's the advantage of this approximation in python/code? I can see it being useful analytically, but what's the advantage in code? The formula has an ^n in it, so doesn't it have the same complexity as n! ?

"Lines" is short for "lines of code" I would say so comments and whitespace would not count. But holistically speaking you are right of course.
