All this is mostly of historic interest. (I am not sure what this exactly means, but
people usually say so when they want to prevent some old garbage...)

omnibus - supposed to collect stock prices from the web
Also example of local web caching. Unfinished and semi-working. Circa end of 2003.realcd - make windows cdrom more unix-readable
Here is a quick dirty solution for situation many people confronted with when trying to install Linux via NFS in a (harsh) m$ environment, or for some other reason want to read ISO9660 cdrom NFS-mounted from windoze. The problem is that the latter does not undertsand Rockridge extension and see only these crappy dos-style 8.3 upper-cases names. Here is a perl script which goes recursively (optional) through directories on cd, consults in each directory fileTRANS.TBL and creates a parallel directory three with symbolic
links which are normal unix long names.
Usage:
realcd -h prints a short help message.
Written in perl. Tested on Linux 2.0.20 with perl 5.003 and on NT 4.0 with perl 5.003_007 (ActiveWare port; no symlinks, just copy, of course). Last updated June 12, 1998.
Mailer - simple SMTP client
Well, it seems that everyone with java compiler wrote his own program which sends emails, and I could not resist too. There is classMailer whose usage is clear from attached
Test.java source file and front-end to it -
GUIMailer. Tested on NT 4.0 with jdk 1.2beta as standalone utility and on IIS 3.0 with ASP 1.0 as server-side component. Last updated February 21, 1998.
JPEGFile, GIFFile - get jpeg and gif file specs
I wrote this when was in the need to produce automaticallyIMAGE
tag attributes for a web site (it used as ASP(spit, spit!)
server-side components).
These are actually two java classes (with two another helper
classes) with methods getSize(), getWidth() and
getHeight(). The only more or less non-trivial thing here -
JPEGFile.class - is merely port/adaptation of appropriate C code
from jpeg-6a package of
Independent JPEG Group.
Tested on NT 4.0 and MacOS with jdk 1.1.4 as standalone utility and on IIS 3.0 with ASP 1.0 as server-side component. Last updated November 12, 1997.
