If a picture’s worth a thousand words, then a picture of a thousand words is worth a million words. And you can quote me on that.

GraphViz is handy graph visualization software. Go to the GraphViz website and check out their Gallery, at least.

When coupled with Perl, GraphViz becomes truly spectacular. Leon Brocard’s GraphViz Perl module just might save you a lot of time. One thing I needed modified on it, however, was the handling of node names. If you wanted a node named “bob@example.com” the module would produce a generic node name of “node141″, which was restrictive for the two things I primarily use the module for (email addresses, and DNS mapping).

What follows is a quick diff to allow one to use arbitrary node and cluster names. They’re just straightforward regexes. They work for everything I use them for, and I haven’t had them bomb out. I think the reserved words (e.g., “graph”) need expanded, as well, but this will work for now.

Here’s a quick script to determine shell, perl, PHP, and groff files, and then run a quick check on them. For my use, I also use the WDG’s ‘validate’ command-line HTML validator, from the OpenBSD ports/packages collection.

RE: keyboard mappings (keymaps) on BeOS and its open-source successor Haiku.

• listarchives.zip – Archive of BEOS-KEYMAPS@LISTSERV.SNAKELEGS.COM mailing list (gone now).
• uni2utf8.zip – Command-line application to print all Unicode values and their respective UTF-8 encodings. Source code included (4KB).
• dvorak-us-standard.zip – Dvorak Standard Keyboard keymap and graphic.
• dvorak-ansi-x4.22-1983.zip – Dvorak ANSI X4.22-1983 keymap and graphic. This is the ‘official’ version that no one uses. It differs from the Standard only in the placement of the keys [ ] { } = +.
• unicode-utf8-list.zip – Text file containing all current Unicode characters and lists them in the following format:

  # SAMPLE: 0xe28da1	#  U+2361	APL FUNCTIONAL SYMBOL UP TACK DIAERESIS 0xe18f8a	#  U+13CA	CHEROKEE LETTER QUU

  The Unicode values and character names are taken from the 3.0 specification database.
