In addition to learning Swift and making smart phone apps, I am still busy with a few other things. A number of websites for personal projects and various objectives, including helping charities.

This website (through early 2024 at least) was running on a CMS program written in C under Linux. I had started writing a new CMS in C++, and although complete through the very basics, I had abandoned that and started working on a CMS in Swift. That is now functional, and I have a number of utilities and things I am going to make on my server that work with the CMS.

Due to helping someone with their telecommunications, I have a hobby now of landline telephony - VOIP. And have experience with Raspberry Pi's - nice little computers.

C++ Builder from Borland - got quite good at it, but never put to use other than a few small things for myself, can't remember how much it cost.
Netscape Navigator. Yes I actually bought that, and am happy I did. Even though it didn't take long for the "free browser" war to start.
Eudora e-mail client. Another thing I paid for early on, and happy with it. Unfortunately moving to another program proved that the data was not really portable.
Redhat Linux. Before the split products, and paid for it, and was happy with Redhat for some time.

Old, ashamed, and forgotten :

various Microsoft MS-DOS versions and Windows versions from Windows 3.11 to Windows NT 4

Just imagine some nice looking footer. I'm too lazy to make it. Copyright yadda yadda, but I really don't care anymore.
