Somewhere to put my meagre contributions to free software.  It beats sticking source files on Pastebin... ;-)

I have been programming since about 1990.  My first program (made with the help of my stepfather Ross) was something like:

```
10 INPUT "What is your name",N$
20 IF TIME$ < "12:00" THEN PRINT "Good morning,";N$ : GOTO 60
30 IF TIME$ < "18:00" THEN PRINT "Good afternoon,";N$ : GOTO 60
40 IF TIME$ < "21:00" THEN PRINT "Good evening,";N$ : GOTO 60
50 IF TIME$ > "21:00" THEN PRINT "Good night,";N$;"!" : GOTO 60
60 GOTO 10
```

What happens at 9 o'clock sharp?  Who knows!  Ah, the mysterious, deterministic and unpredictable computer.  I've confabulated that particular bug; but I'm pretty sure there must have been several in a program that large.

At its peak my Subversion repository had hundreds of projects of various size and states of completion (though tending towards nascency).  Unfortunately I lost it all in a house fire in November 2010.  Including the backups.

So I've been slowly building up again, starting with the few things I salvaged.  If I upload things here then more of my creations may survive the next inevitable calamity. :-)

Below is a list of things I plan to upload here.  Included are some links to blog posts about them at http://ejrh.wordpress.com/.

# Contents #

The items have been triaged into three general categories:
  * Hopefully useful - written to get work done, and have had some effort put in to make them general purpose and/or reliable and/or easy to use.
  * Possibly interesting - things I was working on/playing with for my own amusement/edification.
  * Everything else - things that aren't especially sensitive except insofar as they reveal my programming limitations.  Ah, what's the worst that could happen!
