I’ve been working on a project for a while on my main dev machine, but needed to run it on my laptop too.
Usually copying a site across is quick but this time I re-installed the OS too, everything went OK except for some reason I couldn’t log in to my drupal site.
Eventually I noticed that while the site appeared to be working, every page was being served with a 404 header.
This is fairly well documented on the apache site - but you have to pull
info together from a few pages and the importance of virtual servers is
easy to miss.
I’ve long been impressed with the wayback machine and found it very useful to find things that have disappeared from the rest of the Internet.
I use cvs a lot in software
development and find it a real life saver to be able to restore any
file I have been working on at any point in it’s history. This really
helps me to find out when and why things went wrong, saving me from
making the same mistakes again.
