This site used to be static HTML pages but now uses the Joomla Content Management System (CMS); why the change?

There are two different questions here:

  1. Why Content Management Systems? The short answer is that they makes life easier.
  2. Why Joomla? Because I was already familiar with it.

New PCs ship with Windows7, which offers 32-bit or 64-bit versions. 32-bit operating systems (all of them, not just Windows) are limited to only using 4GB of RAM - if you want more (and who wouldn't), you need the 64-bit version. 64-bit Windows 7 allows between 8 and 192GB of memory depending on which version you have (the current AMD64 chip set maximum is 256TB, but even I don't need that...)

If you're installing MS Office, you get to pick which version of Office you want - 32 or 64-bit. The default and recommended option is the 32-bit version, which runs just fine on both 32 and 64-bit windows.

So far, so good.

Then we get to MS Access, and things get a bit ugly:

Poor security can lend a false sense of security, encouraging you to relax your guard and making it more likely that you will suffer loss or damage from bad guys.
