This weekend, I indulged in the popular pastime of "formatting the hard disk and reinstalling the operating system". The machine in question had been accruing cruft for about 6 years, so it was probably about time, although the act was finally prompted by some particularly inadvisable malware tinkering.
As I went through the usual setting of options, installation of important software, and disabling of the usual irritants (if I have a "recycle bin", then I really don't need a confirmation dialogue every time I delete something), my mind returned to the question of exactly how much time it takes to turn a fresh install into something usable. Even just installing all the service packs and 'critical updates' takes several hours and half a dozen reboots.
Which in turn made me think of the new US President. As far as I can tell from the news reports, he has been reconfiguring his country. Enabling the FOIA that was disabled by the previous user; removing the Guantanamo extension, and so on. Wonder how long all that will take.
