Naïve question, but doesn't amount of brute-force search depend on the particular solver used? I'm vaguely aware of finite domain something or other but curious about the affordances prolog has for using different solvers over dif

Oh well. It's clear you read my posts as personal or uncouth attacks. I genuinely disagree and tried to explicate intent clearly, but c'est la vie. IMHO, it's helpful to separate out ideas and actions from identity, freeing u

Dyalog doesn't have an explicit implementation for maps, but you get the same effect with column-major table stores and the implicit hashmap backing of the search-like primitives [0]. E.g. keys←'foo' 'bar' &#x

The wall you describe is a legitimate problem with the current APL on-ramp. One of my talks last year was on this exact issue [0]. It's definitely not you. That said, it's also really not a limitation with the languages either. In

Late to the game here but... > can you find the bug? Several stand out immediately: - Two syntax errors: unclosed single quote in '⍳n n←⍴⍵ and no right operand in the second use of Jot (∘). It's not clear how those could have s

First off, thanks for continuing this exchange with me. Text communication between strangers is fraught with miscommunication perils left and right, so hanging in there is a really nice gesture. Cheers. It's so weird, though. Everythin

The original post I replied to made an explicit claim with zero evidentiary support, so your demands for rigor are a bit lopsided. But more to the point, I'm really not saying anything about which metric is better or whatnot. What does

Just... no. What are you even trying to compare? UX of a language matters. Clarity, thinking paradigm, expressability etc. all matter and are affected by the visual size of code. A one line solution takes up very little visual real estate

That is quite beautiful. Thanks for sharing. Are you familiar with Japanese grass script? It has quite a different feel than the Mongolian, but it's a type of Japanese cursive that flows really nicely IMHO: https://ja.wikipe

Beautiful. I wasn't aware of Li Bai (李白). Took a bit of searching, but the original looks to be called 独坐敬亭山: 獨坐敬亭山衆鳥高飛盡孤雲獨去閒相看兩不厭只有敬亭山 This is gorgeous. Thank you for sharing!

First time I've heard of the disjoint-set data structure. For a DSF implementation, Wikipedia [0] gives the wildest asymptotic complexity I've seen, using the inverse Ackermann function ! "Almost constant time" indeed.

Ouch. That tab error is a bug in libyaml, the YAML loader used by PyYAML. It's still stuck on YAML 1.1, but the spec explicitly allows tabs as whitespace, though they don't count as indentation semantics.[0] The same is true in YA

Not only does the spec say that, but it was an explicit goal of Ingy döt Net, the designer of YAML.

Do you know APL? It's pretty asinine to jump directly deep into a technical document and complain that something is indecipherable to you. The 210 excerpt is completely readable once you've gone through the dissertation, especiall

Is a happy life a good life? I'm really not sure, but pursuit of the former is more of a modern conception of value as far as I can tell. Living a happy life and living a meaningful life aren't entirely the same thing. Not that yo

Cool. A Dijkstra note. Thanks for sharing. The distributivity argument is a bit sketchy, though. It defines g.p := p▫q, meaning that g implicitly depends on q, but then writes f(y▫z) = f(g.y) and fy▫fz = g.f(y), where in the first instance

It has struck me for a while that associativity can be seen as a higher-order commutativity. Specifically, for the real numbers, it's associativity just says that you can commute the order in which you evaluate the multiplication map.

Not just Apache, but POSIX shell syntax! It's called Tilde Expansion[0], so in your dash, bash, whatever, ~USER expands to the home directory of USER. This is the general form of standard "bare tilde" syntax as a stand-in for
