Various categories of things useful for various reasons.

Data

• abundance discrepancy factors - a compilation of every ADF in the literature, sortable and selectable by various nebular properties.
• supernova ejecta dust masses - a compilation of literature estimates of dust masses in supernova ejecta.
• list of ionisation potentials - in eV and in Å
• list of chemical elements - name, symbol, atomic number, nothing else

Web pages

• www.sndust.org - SNDUST project web pages
• evolvedstars.space - the Nearby Evolved Stars Survey
• mocassin.nebulousresearch.org - 3d photoionisation and radiative transfer code whose web pages I maintain.

Press

• a page about V458 Vul. Its discovery was announced in November 2008 (see our paper) and attracted some press coverage. Some images are here.
• Noches de galaxias... y cerveza - Chile's La Tercera report on an outreach event I took part in. Never mind that they got my surname wrong, I liked their write-up a lot anyway.

Computing

• how to program autocomplete for your codes
• packaging software for distribution via repositories
• command line useful things to know

A game

• CMBR: a clone of 2048
• CMBR2: because CMBR was not maddening enough

Climate visualisations

• Death spiral - a visualisation of the decline of Arctic sea ice.
• Global warming - a visualisation of the way global temperatures are increasing.
• CO₂ and temperature - a visualisation of their correlation.

Others

• memorabiliser - generate memorable names for objects that only have boring catalogue designations
• I can see some... - a response to a seminar entitled "A global warming sceptic's case - can you see any holes?
• Planets rotating - see how planetary rotation periods compare to each other.
• Earth rotating in real time - it is probably faster than you would have thought.
• 1883-2013: All the exploding stars - 130 years of supernovae
