I haven’t followed recent development of JavaScript all that closely so my knowledge is somewhat outdated. However, the optimisations that make JS performance close to C in some cases are really recent. Some of the tricks are old, such as

No, unfortunately that is not the case. Lookup happens at execution of the byte code, because variables cannot be looked up at byte compilation. Consider the following case: x = 1 local({ assign(user_input, 2)

As far as I know byte-compiling won’t actually alleviate the repeated name lookup (or does it?). Unless the R byte compiler is fiendishly clever, every single name lookup in the loop body will still incur what essentially amounts to a `get(

Python and similar dynamic languages suffer from the fact that every name access (variable, function, etc) incurs a dynamic lookup of that name in a (nested) dictionary. Statically compiled languages don’t have this. There are fairly rece

Yeah, don’t understand the downvotes. It’s an interesting question, and the whole subject of Lamarckism is far from trivially obsolete. Richard Dawkins’ The Blind Watchmaker contains a coherent and convincing argument why Lamarckism is ac

Lamarckism isn’t about epigenetics, nor vice-versa. Some people are calling epigenetic inheritance Lamarckism, but many (in my experience, most) colleagues reject this label as inaccurate. For one thing, although epigenetic inheritance on

In a way, all mutations in single-celled organisms that are inherited by daughter cells are acquired during the mother’s life-time, so they’d all meet some definition of Lamarckism. CRISPR isn’t that special in this regard. Many evolution

I agree with this. We’ve had this discussion on HN before (at least once) [1]. And the claim that Turing “bore the [chemical castration] with fortitude” is ludicrous, and the more likely explanation is that he had erected a facade of equani

To be fair, you can do the same for iTerm (or any application, really) by using other tools. Quicksilver, for instance, allows you to define system-wide hotkeys.

I get “∀X[∅∉X⟹∃f:X→⋃X∀A∈X(f(A)∈A)]” – i.e. the Unicode representation (without having configured anything). I’d even argue that this is correct/desired in this particular case, although of course not all formulae can be correctly expre

That’s probably not a very reliable proxy for age estimation though (for reasons alluded to by sampo, and simply because telomere length varies across individuals regardless of age). It’s probably much easier and more reliable to measure th

Here: var factory = makeCar; The whole point of having first-class functions is that you can assign them. The problem a factory solves is precisely the lack of this assignability (which is why a constructor function is wrapped in a

Many/most widely used “quicksort” implementations are actually introsort (in particular, `std::sort` is), and thus O(nlogn) worst case.
