For people not wanting to use Google, I've written a script "dateparse"[1] that allows to do the same: $ TZ=America/Chicago dateparse '2pm PT' 2pm PT: assuming PDT 1647464400 Wed Mar 16 16:00:00

I think this might be ambiguous, since "Pacific/$city" refers to a part of the world that the west of the US ("PT") is not part of. I've decided to add "Pacific Time" to my "dateparse"[1] sc

Yes, they are solving the storage and RAM challenges partially by throwing CPU at it: not using native pointers, switching between multiple struct sizes where the original had one, compressed integer values, etc., also they restructured dra

A side note left out in the history mentioned here is that Igor first[1] developed two third-party modules for Apache, mod_deflate and mod_accel[2]. I think especially the latter was a big step towards NGINX already. It was a much more capa

Since "recur" only allows to recurse to the closest recursion point (a loop or the enclosing function definition), what if it just used JVM's "goto"? Or, if the JVM didn't have a goto, but any kind of iteration

If the question is about deciding what kind of heating to use, more likely than not the choice will be for new gear. For a new house the choice would be between one of the modern furnaces or electric heating. For someone with an old furnace

Electricity generation efficiency from coal is only 25-50% according to [1]. Heating efficiency of modern home furnaces is typically way above 90% according to [2]. Power transmission efficiency across the power grid is around 94% according

In section 3.4 you end with "we consider marginal carbon intensity to be no practical signal for demand management at this point due to high uncertainties". But for the direct actual ecological value that would be the only numbe

by pflanze 5y ago
It's funny that you defend your view using Haskell, as I was replying with Haskell in mind. If you use the state monad, you encode local side effects. Then you use runState in a function that has a non-monadic type--a pure function. Fe

Whether closures are or are not allowed to mutate state depends on the programming language (or the aim of the programmer, if the programming language doesn't force their way). Closures are a syntactical building block helping function

AFAICT the core of FP is referential transparency. The "meat" of FP are the tools available which allow to (comfortably) increase the portion of the program that is referentially transparent. Immutability, first class functions, l
