My brain has become a leaky bucket!
When I was a young telecommunications research engineer and joined a team designing a prototype digital switching system codenamed Empress (you can read about it here), I learnt of the useful technique called a 'leaky bucket' (described here). A fault counter is decreased at a preset rate and increased for each incident. If it ever reaches a defined level, an alarm is raised.
In the case of my brain the situation seems to be reversed. Useful bits of information leak away at a random but increasing rate, and the challenge is to keep adding to the bucket so that it remains a useful resource. I guess that reminiscing, such as suddenly remembering the Empress project, helps keep the bucket full; anyway that's my excuse for this increasing old-age activity.
Yesterday's challenge was to remember how to set a Drupal or Backdrop website so that the user is not aware that it is installed in a subdirectory. This is so that a page with actual address (URL) of www.mydomain.net/backdrop/page-1 appears to users (and search engines) as, more simply, www.mydomain.net/page-1.
Well, I eventually remembered what to do, though at the moment I cannot recall exactly what is happening in those .htaccess files. Note to self: write notes as you do things, just as you were trained to do all those years ago.
