another funny html thingy: blockquote

By Hal Canary

Good html:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html><head><title></title></head><body>
<div>
<blockquote>
<div>
X
</div>
</blockquote>
</div>
</body></html>

Bad html:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html><head><title></title></head><body>
<div>
<blockquote>
X
</blockquote>
</div>
</body></html>

Check it yourself.

Possibly a medusa.

By Hal Canary

Dean: THEY’RE HERE!!

Hank: Dude, sit down! We have to play it cool. Observe how I scope out my mystery date whilst I pretend to look at my watch- Holy moley, look at my date! She’s a super villain! Possibly a medusa. Dean, I am not kidding. She has rope for hair and a shiny costume! Aw, not fair, she’s wearing goggles! Told ya she would dig my Batman suit, but no!

lpr-text for CUPS

By Hal Canary

If you are using CUPS for your printing, there is no reason to continue using Enscript.

#!/bin/sh
#DTPD#
# http://cups.org/documentation.php/options.html
# ~/bin/lpr-2col-text
exec lpr -o page-left=36 \
        -o page-right=36 \
        -o page-top=72 \
        -o page-bottom=36 \
        -o columns=2 \
        -o landscape \
        -o cpi=16.842 \
        -o lpi=10.1052 "$@"
# 80 columns width x 70 columns high x 2 columns

That’s about 140 80-character lines per page, in two columns. Somewhat analagous to “enscript -2r -B”. I leave room at the left margin for hole-punches, to make binding easier.

In theory, this should handle Unicode characters much better than enscript or a2ps does. If you are still having issues with unicode printing, try “ooffice - file”.

Here’s the one-column version:

#!/bin/sh
#DTPD#
# http://cups.org/documentation.php/options.html
# ~/bin/lpr-1col-text
exec lpr -o page-left=72 \
        -o page-right=36 \
        -o page-top=36 \
        -o page-bottom=36 \
        -o cpi=11.43 -o lpi=6.858 "$@"
# 80 columns width x 68 columns high

the library again?

By Hal Canary

I read Blind Lake today. New hypothesis: RCW does not write bad books.
