The Mother of All Demos, presented by Douglas Engelbart (1968)

If you have never seen this, I recommend it.  Douglas Engelbart’s December 9, 1968, extraordinarily prescient demonstration of experimental computer technologies that are now ubiquitous. The live demonstration featured the introduction of the computer mouse, video conferencing, teleconferencing, hypertext, word … Continue reading

The SAMI Data Archive: A Prototype of An Archive of the Future?

Astronomy data sets are not simply exploding in size – they are exploding in complexity too. Witness the data sets obtained from integral-field spectroscopy (IFS).  While the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) survey has exceeded measurements of 1,000 galaxies, surveys such … Continue reading
