Long time hobbyist and professional firmware programmer.

I was bitten by the bug in 1978 when my father brought home a shiny new Radio Shack TRS-80. I worked my way through David Lein's BASIC tutorial and started writing little games. Then came the Level II upgrade, with 12K of RAM and a new BASIC with access to machine language routines through the USR() built-in, and that was that.

Ever since, I've worked with small systems, mostly Microchip's 8-bit PICs.

comment Why does Cem Kaner consider a test not revealing a bug a waste of time?
@Blrfl only problem with that is that Mr Schrödinger is dead. Oh, wait... um...

comment What is the meaning of # in R5RS Scheme number literals
Agreed. 0's work fine when using straight numbers etc. The #'s would require numbers be handled symbolically (treating each run of #'s as both 0's and 9's to determine how many digits in the result of an operation are indeterminate and should be replaced with #'s) -- so that's probably why the meaning wasn't specified, only the effect of making a number inexact.

comment What is the meaning of # in R5RS Scheme number literals
thanks for pointing that out -- I see it now in the grammar. Ok, so it seems to have been originally intended to represent lack of precision (ie a measurement with N significant figures), although implementations appear to simply replace #'s with 0's and mark the number inexact, then forget about the #'s, which seems to defeat the purpose. Also, I've just looked at R6RS, which has dropped this.

comment What is the meaning of # in R5RS Scheme number literals
Yes, that is what the standard says, which I noted indirectly in my question. It does not, however, define the meaning of 123#4. I was wondering if there was a specification of the meaning of # in place of a digit in the formal semantics. My assumption is that it was probably intended for symbolic manipulation of numbers (ie sig-figs and how they propagate) but it's not specified in the standard's English text.

Yes, I only want one problem at a time :D

comment Does JAXP natively parse HTML?
Thanks, that pretty much sums up what I'd surmised, that you need well formed XML for JAXP. I'll look through and find something quick-n-dirty, either a converter or html parser. Or even (shudder) cruft a partial parser :)
