Why does the bubble sort continue to the end of the array on every pass, when it could stop one earlier each time?

As well as being Unix backwards, it's also a recursive acronym; Xinu is not Unix.

Base 26 or 36? Is 'a' 0 or 10? Does 's' overflow to the next column, like 09 in octal?

You're correct. Perhaps the up-voters were thinking it must just be better to report the piping. Which it is, but that doesn't make the comment valid.

GNU sort has a --compress-program option that can help if you're really tight on scratch space, e.g. lzop(1). The -T option or TMPDIR environment variable lets you state a filesystem with more free space can be used instead.

If you're going to process this file a lot, and it's straightforward text, then consider compressing it with lzop(1). lzop's fast as compressing, and very fast at decompressing, and the overhead of having to decompress on every read throug

You test with "he" versus "him" in the reply to the question, not by replacing "who/whom" in the question itself. So the answer to "whom to follow" is "follow him", not "follow he".

Maybe Twitter should consider changing to "Whom to follow" as the quirkiness would stand out to those unfamiliar with "whom". May help partially offset the slight staidness.

Almost certainly that one. Mr Burns, is that you? You've had me accessing bits that hadn't been scrubbed in a long time and have suffered some rot. Have you just arrived at number 63 or just left? There's a Dorset LUG if you're interest

You might sound like Inspector Morse; he was repeatedly correcting Lewis. Here in England, "everyone" doesn't say "who" when they mean "whom".

As a sinister southpaw myself, I've never understood why fellow left-handers grip the pen in an unusual curled-round fashion such that their hand rests on what's just written. I hold it like a right-handed person would. http://blogs.sunti

"ed was a command-line editor that worked identically to the colon-commands in vi and vim—in fact, you can press Q to get into ed mode (then type vi to get back into vim)." This is wrong. Pressing Q in vi quits visual mode and returns you

No, vi often isn't installed, e.g. on Linux ADSL routers. If there is one editor it will be ed(1), the one true editor. :) That's why everyone should know it. Besides, it is a bit easier to use ed blind to edit a file from a mental imag

Exactly. Emacs didn't start on Unix IIRC and seems to prefer to have everything built in. vi was created by Bill Joy on Unix and wanted to work with the rich language of shell commands from the start, as ed(1) did, so it concentrated on e

Surely Caps Lock is already mapped to Ctrl? Then Ctrl-[ for Escape becomes easier as do all the other Ctrl combinations.

HJKL's location on a QWERTY keyboard directly influenced them being chosen. They were to hand under the right hand, and mnemonically, ^H is BS, ^J is LF, ^K is VT (vertical tab) which at least keys the vertical connection going, and L is j

vi commands $, %. and ^ are conveniently placed on QWERTY; Shift-4/5/6. If you use the one true style of braces for your C code then you can move through if-else-if chains quickly. $ moves to the end of the line, placing you on the open

I think he's saying that the main event loop has called a callback, only to have that callback either call the main event loop, or something similar that processes events until a certain condition, and that in turn may cause other callbacks

ssh(1) only compresses if configured too, see the -C option.
