Former responsibilities I still sometimes get asked about:

UCL Observatory
PATT Rolling Grant
PHAS1102: Physics of the Universe. Course no longer delivered.
PHAS2112: Astrophysical Processes, Nebulae to Stars
  I have 'retired' my web pages for this course, and they are no longer maintained. My PHAS3135 may be more useful to you.
Peer Assisted Learning (PALs)
Asteroid Computers
Postgraduate admissions (for those wanting to apply for PhDs) – now administered by Dr Achilleos.


Refereed papers ("refereed" as judged by ADS)

Agitprop: Support Open Computing

MS Windoze Sins
MS-Word attachments are a BAD THING (especially when easy-to-use, free, open-source tools are available).
Oppose software patents
Find out what "trusted computing" really means (here's another view) – for example, it could be illegal even to look for security holes installed by 'trustworthy' companies on the computer that YOU own with software that YOU spend your good money on.
Why is open source a good thing? One reason (among many) is the serial malpractice of companies like Microsoft, who have fallen foul of antitrust laws in the US, the EU, and Asia
Oh, and let's not forget the numerous class actions brought against them in many US states for (illegally) anticompetitive practices.
Or the fact that they've almost certainly installed spyware on your PC.
The truth behind so-called 'Secure Boot'
Real programmers use emacs


dipso – golden oldie spectrum manipulation/plotting/analysis software. This is my own development version, not the Starlink release (source code).
pgpix – mid-level plotting package (largely authored by Keith Smith, and based on pgplot) offering fine control and good quality output (source code).
vapid – Interstellar profile-fitting routine ('voigt absorption-profile [interstellar] dabbler'). Fortran source, linux i86 executable & documentation (paper)
[Best contact me if you plan to use any of this stuff – there are probably more-recent versions than posted here...]
