Rather embarassingly, it appears that for the last few months my computer has been leading a double life as a warez server. Some nasty hackers exploited the ftp facility that I had naively set up to allow you bloggers upload objects for linking in the blog posts. The side effect was terrible performance of my web page. All this unpleasantness has now been eradicated (all those hundreds of subdirectories under FTPROOT have finally been deleted) and you should find the web site back to its speedy best. The FTP facility has been removed until I can work out a way to do it safely and easily but as I don’t believe it was ever used by non-hackers I don’t expect this will be a problem.
