This reminded me of a prior discussion[0] on bulk data generation in SQLite with Rust (vs Python vs PyPy) which previously led me to trying out two different techniques using just SQLite[1]. The approach here is so similar I tried my prior

As a specific example I routinely ran into forms that rendered like this (hidden scrollbars in three different browsers concealing content, though Safari rendered _just_ enough text that it might indicate there was more to see): https:&#x2

I have tried with both python 2.7.18 and python 3.8.6 using Emacs 27.1 and the excerpt works without issue for me; I have no configuration (emacs -Q) beyond pointing org to my virtual environment and allowing python evaluation in org-babel:

The chromium bug ticketing system is all but unreadable to me. The OP ticket itself is closed and links to another instead, is there recent movement of note? I know igalia[0] was working on this but I haven't been following the bug tra

Emacs-specific solution, but there is this[0] example of J and prettify-symbols-mode, the results look something like this: quicksort=: (($:@(<#[) , (=#[) , $:@(>#[)) ({~ ?@#)) ^: (1<#) quicksort ⤆ ((∇⍛(<#⊣) , (=#⊣) ,

The old mobile interface is entirely text, it removes the thumbnails present in the i. subdomain (also available with a trailing /.compact) -- the fact that there are so many different interfaces is a little baffling to me, but the tex

I've been teaching myself J and dabbled in a few other APL-family languages before that (Klong and Dyalog's APL mostly). I don't have any specific goal in mind and have been doing it for fun more than anything -- I recently t

This is a good one. I've used this in the past in order to get onto IPv6-only networks as well. In my case I don't have IPv6 enabled on my home internet (thanks Verizon!) and I had a tiny virtual machine with Vultr, which at their

Not long ago there was a post about using English language instead of the J symbology[0] but the end result isn't meaningfully easier to understand because of all the prerequisite knowledge of how evaluation works etc., once you'v

Always a pleasant surprise to find niche or mundane uses of array languages. I really appreciate the explication because it made it possible for me to follow along in J - there's vanishingly little material to patiently explain bits li

I read the Klong book [0] and for me it "clicked" in a way that J/K never had. The author did a really nice job paring down the language and cleaning up some of the ambiguities in a way that made it approachable. Also, after

As far as I know, this is a peculiarity of APL resulting from Iverson's stance on the language as a "tool for thought"[0]. The best explanation I've heard is that "binary" is most apt to number systems (or matr

Depending on how involved the language you are interpreting is, you might get by having only read chapter 6 of The AWK Programming Language[0] (linked in the article), which covers "Little Languages", including what it terms an as
