I don't know Olin Shivers but I've read enough of his writing to know that this acknowledgements section was written with tongue in cheek, and in fact it's a funny enough piece of writing that I've shared it a number of times like the grandparent comment did.

I guess the author was thinking of how cat's original purpose is to concatenate multiple files, not show just one file. (But I certainly don't think using cat in the latter way is a misuse.)

There's also a commonly noted "unnecessary use of cat" where people do this:

  cat file.txt | grep foo

instead of this:

  <file.txt grep.foo

but that's not relevant to bat (which can be used unnecessarily in the same way).

(1) lack of primitive hash tables (2) lack of primitive arrays

I'll note that if there are primitive arrays and the compiler optimizes arithmetic, the rest of the hash table can be implemented in Bel.

Also, maybe a Sufficiently Smart Compiler could prove that a list's cdrs will never change, store it in cdr-coded form, and treat it like an array (with the ability to zoom right to, say, element 74087 without chasing a bunch of pointers).

http://productionadvice.co.uk/no-stair-steps-in-digital-audi...

The “stair-steps” you see in your DAW when you zoom up on a digital waveform only exist inside the computer. [...] When digital audio is played back in the Real World, the reconstruction filter doesn’t reproduce those stair-steps – and the audio becomes truly analogue again.

This all sounds like it would make an interesting blogpost/article if you're into writing one.

I'm surprised people put up with them

I don't like them at all but I do most of my Netflixing on my iPhone, where it doesn't happen.

(When I do go to the Netflix site in a web browser I sometimes temporarily use "Mute site" which is a pretty crazy thing for a site for watching movies to make you want to do!)

“[A]lmost anything ending in ‘x’ may form plurals in ‘-xen’ (see VAXen and boxen in the main text). Even words ending in phonetic /k/ alone are sometimes treated this way; e.g., ‘soxen’ for a bunch of socks. Other funny plurals are the Hebrew-style ‘frobbotzim’ for the plural of ‘frobbozz’ (see frobnitz) and ‘Unices’ and ‘Twenices’ (rather than ‘Unixes’ and ‘Twenexes’; see Unix, TWENEX in main text). [...] The pattern here [...] is generalization of an inflectional rule that in English is either an import or a fossil (such as the Hebrew plural ending ‘-im’, or the Anglo-Saxon plural suffix ‘-en’) to cases where it isn't normally considered to apply. This [...] is grammatical creativity, a form of playfulness.”

I upvoted this because it seems to make some good points and I think the topic is interesting and important, but I can't understand why the "Then, why some free software projects use xz?" section does not mention xz's main selling point of being better than other commonly used alternatives at compressing things to smaller sizes.

That is what it means. Note that the lines ("edges" in graph theory terms) can cross each other.

Nelson asked: What is the smallest number of colors that you’d need to color any such graph, even one formed by linking an infinite number of vertices?

The Wikipedia page describes the infinite-vertices version of this graph as

an infinite graph with all points of the plane as vertices and with an edge between two vertices if and only if the distance between the two points is 1.

This of course is impossible to draw but Wikipedia shows seven-vertex and ten-vertex subgraphs of it:

I'll look into xmllint. I currently use HTML Tidy for this:

  tidy -xml -indent -wrap 0

  tidy -xml -indent -wrap 0 -quiet

Formatting the quote like this makes it too wide to be readable on my phone without repeatedly scrolling right then left. Even in landscape mode the first line ends with the "b" of "brightly painted".

A lot of people format quotes with italics, as in this example:

RFC 2392 Message-ID values are supposed to be unique, but they may not be if the software generating them is buggy. I remember reading somewhere about some email program that assumed they were unique (in effect using them as a natural key). If you were unlucky enough to get messages with identical Message-ID values, all but one would disappear.
