You do not need to be on all 14 to find Beeper useful! Even if you only use a few you might still want them to be together in a single app. As to why you might be on several different chat networks, you might have different friend or family circles that use different chat networks and may have failed to convinced them to move to a single one or, like me, may think it is a bad use of time to even attempt to convince them to. I'm using Beeper for WhatsApp, Telegram, Facebook Messenger and Discord and it's great!

Oh, absolutely! I should have said before that I edited many file types in Vim on that netbook and syntax highlighting was lighting fast on all types except LaTeX. Sorry if I gave the wrong impression. Unfortunately for me, LaTeX is by far what I most wrote at the time, so it was an annoying problem.

Amen to that! I've even been on the other side of this issue, with some Emacs packages I've written. I've received reports of some operations being very slow that I've been unable to reproduce (even though I continue to use underpowered hardware because I value battery life more than speed —I'm typing this, in Emacs, on a 10 year old Chromebook!).

The slowness I experienced for LaTeX files happened even without any third-party plugins installed, using a one-line .vimrc that only turned on syntax highlighting. So I think it is unfair to say "the slowness has nothing to do with Vim itself". Probably also "or the low power of the netbook" is unjustified, in the sense that the tips in :help tex-slow do likely solve the problem on computers a little beefier than my old netbook (which is probably more than 15 years old at this point). I mean, those suggestions are in the official Vim documentation presumably because they did work for someone.

Think of it this way: if the slowness of LaTeX syntax-highlighting were not a problem in Vim itself (where by "Vim itself" I'm including the vimscript files that ship with Vim, not just the executable), would it be documented in the official Vim documentation?

Also, I am constantly amazed at how concise K is, easily rivaling not only conventional languages but also much larger array languages like APL or J. Arthur Whitney's taste in selecting primitives is out of this world.

If the necessary temporary arrays are really huge, array programmers will just do the computation in chunks that fit comfortably in memory.

Close, they are called "idioms".

The plus should be an asterisk, but yes, that is an idiom the ngn/k interpreter recognizes.
