Tool assortment:  the good, the bad, and the useless

Those (theoretically) one-off hacks that I still use or just could never bring myself to delete are available here for your dubious benefit.  There is no documentation or legalese except what you find in the source code itself.  Kind of reminds you of the good old days, doesn't it?  Share and enjoy.

libdstr

Dstr ("Dave's string class") is a C++ class that I use instead of std::string.  It has gotten cloned into so many projects now that I've made a shared library just to reduce the number of copies.

• libdstr-20080124.tar.bz2

Jukebox-related

This nontrivial hack has a few extras that go with it.

• jukebox.cc:  Play sound files (or whatever) in random order forever.  It will play every song in the playlist exactly once before repeating any.  State is preserved between runs.  Needs libdstr (see above).
• aplay-rt.c:  Run aplay with realtime priority.  Needs to be suid root.
• jukebox_prep:  Script that I use with jukebox.
• jukebox_play:  Script that I use with jukebox.

LaTeX hacks

These packages work with document class article.

• blockquote.sty:  Provides blockquote environment that is like quotation but without indentation.
• draftfoot.sty:  Puts *** DRAFT *** in the footer of every page.
• sssubsection.sty:  Turns paragraphs into numbered subsubsubsections.
• timestamp.sty:  Provides \timestamp command to include current date and time in the form YYYY-MM-DD HH:MM.

• qdgamma.c:  quick and dirty replacement for pnmgamma, which broke at some point.
• qdnlfilt.c:  nonlinear smoothing of PPMs.
• qdsort.cc:  replacement for sort that does a better job with Latin-1.  Uses libdstr (see above).
