Unicode does have one-eighth blocks, which can be handy when a special font isn't convenient. ▁▂▃▄▅▆▇█

Though looking at the code now it seems registers have been memory-mapped at 0x10000 and above?

It's very common; the norm even. My point was that "A hash (function) is any function that maps a big variable-length data structure to a smaller (fixed-length) data structure." is incorrect; the source size isn't relevant.

I have hash functions that work on less bytes than the length of the hash they produce.

I haven't read the spec. or followed the topic in general, but from a quick glance at it: the size of the registers isn't given, and the registers aren't memory-mapped. Why not use an integer instead of Cell? 42 is memory address 42, -3 is

Text files are great, especially if one's the Unix shell skills to quickly manipulate and query them without having to write a program. But XML is often overkill compared to a simpler text format.

The problem is we're mainly conditioned to expect the condition up front, notwithstanding Perl's initial slide down this slippery slope. Ugly syntax seems an argument for improving the syntax, not changing the grammar. if mum.birthday

I think you're getting confused with implementing sed in sed. ;-)

Sorry, it's isn't comprehensive but more of an introduction, e.g. no mention of the difference between pattern and hold space or the n/N commands.

Which is why it's odd that most washrooms have you pull a door by the handle to exit, a handle many others have probably touched without washing their hands. Ikea is one place that comes to mind that avoids this, instead having a sequence o

This is something to skim and spot bits you didn’t know, leading you to the relevant bit of the fine manual. It has errors though, e.g. /\<\d\d\d\d\> : Search for exactly 4 digit numbers /\D\d\d\d\d\D : Search for exac

For GNU tar these days that's true, unless you can be sure $TAPE is in its environment. Historically, tar defaulted to a tape device, e.g. /dev/mt0, and you still find vestiges of that, e.g. OpenBSD defaults to /dev/rst0. IOW, specify "f -"

I disagree. As a programmer I can represent inputs and outputs as text and write code to do intended transformations. As a quick ad hoc test I can easily knock up a shell pipeline to give confidence in those results, even if it would be t

What's not that simple? I didn't say anything was, just citing a reference. Did you mean to reply to the parent?

IIRC Aho, Weinberger, and Kernighan's excellent slim tome _The Awk Programming Language_ implements something similar; awk is used to generate the awk with Field1 replaced by $1, etc.

Perhaps they think http://en.wikipedia.org/wiki/Broken_windows_theory may be applicable and it's best to nip stuff in the bud.

Those globs should be protected from the shell otherwise ./bc is going to alter tr's arguments.

The reason for preferring sed 42q instead of head -n 42 is because head didn't used to exist. IIRC it was created at Berkeley and for some years there were many systems that didn't have it. It does seem a bit superfluous when all it could

Does this mean I'm not alone in thinking Yegge could cut half his prose and create a better post?
