Simon's Work Place
These are my work related web pages. For my fun pages and more about me
you probably want to meander over to
Tardis where my real
home page is located.
As you might have guessed I work here, in the
Department of Computer Science,
Edinburgh University as a Computing Officer.
I'm currently playing around with SSL servers and certificates. You can
visit the department's secure server
(If its running - I am playing around with it, after all). You can also take
a look at the beginnings of a
Departmental Certification Authority
I spend most of my time looking after
- Printing We run the LPRng
print spooling package, with a locally written back end that handles
automatic format conversion and a number of powerful page manipulation options.
More information is available from the
- LaTeX and TeX We're running an old and out of date TeX installation.
Its a locally constructed tree based around Karl Berry's kpathsea distribution,
that rotted for two years whilst it was unsupported. We're in the process
of building a new TeX tree based aroung teTeX, which we will migrate over to
shortly. There is a local LaTeX page, but be
careful, as its not been updated recently.
- The Web Server We use Apache
as our web server, with the PHP/FI server
side scripting extensions. We use
cgiwrap to create a more secure seperation between the web server and its
CGIs. As mentioned above we're also using the
Apache-SSL patches in
conjunction with SSLeay
to provide a secure web service.
- The Web Cache In an attempt to reduce both our local and
international bandwidth usage we run a caching web proxy. The proxy
is based around the Squid cache
software, I'm also evaluating running a
JunkBuster interface to
it for those who are really concerned about privacy. Much more information
on the cache will be linked from here soon.
- Web statistics We use
to generate statistics for our web servers.
I also play around with a large number of smaller packages. Whilst their
not part of the core system, I do still tend to get asked the odd question
- GNU m4
- Assorted cryptography routines As you might have guessed from
my real home page I'm
firmly in favour of freely available strong cryptography. To this end
I maintain a varied library of cryptographic tools, including SSLeay.
More information should be available from the
local crypto homepage
- CVS A version control system. This is currently being evaluated
as a means of tracking local modifications to installed packages - I'm
supposed to be writing some documentation on the subject.
- lynx The free, text-only web browser.
See the local copy
of the documentation or visit the
main lynx site
- html2ps A very powerful html to postscript convertor. More
information is available from the
- The info and man page readersYou can read any
info page thats installed on the system over
- latex2html We use this to generate HTML versions of our internal
documentation (when people actually bother to create HTML files, rather
than just making them available as DVI or PDF - yuck). It generates much
better results if you take the time to write a style file for it (see
our technotes for an example). One of these days
I'll write something on how to go about writing a style files. In the
mean time mailing me for more information
probably won't hurt.
- gd The gd GIF manipulation library. We've got a
local copy of the documentaion or you might
want to take a look at the main gd
- gv An alternative ghostscript front end. Documentation is
available from the
