Useful Links

One of the things we did when we first built websites in the late 1990’s was to provide lists of links which might be useful to other people. Better search engines and dominant marketplaces have limited the use of a “List of Links”. Undeterred by fashion, here are the various links to areas I’ve found useful in recent months, particularly regarding the geoscience consulting business. Practically all consultants have a website and actively use connections within LinkedIn, however, in geoscience there is not a single place to go for clients to find commercially available products and consulting services. Or if there is please let me know about it.

Please feel free to add your own favourite links in the comments and I will add them to the list.

Diversions ….

I didn’t make much coding progress over the weekend, but I did find my 1975 copy of Martin Gardner’s book “Mathematical Puzzles and Diversions”. In the photo you can see a hexaflexagon that I constructed yesterday after reading this chapter of the book for the first time in over 40 years. Flexagons are well worth looking at, especially if you have 10 year old children. I found a few templates on the web with some interesting design ideas.

I also read the Polyominoes chapter, possibly for the first time. Since it was chapter nine I’m not sure that ever read it before..I seem to remember finding the book quite difficult to understand when I was 10. The Polynominoes piece is interesting, but the B&W graphics are really poor and rather uninspiring. I’m sure later books and versions of this text ( and its follow ups) had better graphics.

p.s. I found the book on a bookshelf in my house in Dublin, so no need to search through boxes of books in my loft in Mayo !

The Software Platform

This blog is already lagging a few days behind actual events, but that is probably of no consequence to the few readers likely to encounter it. Since I had decided to code in BBC basic, I was faced with two options

  1. Get the old BBC micro from the loft. I know it works, but it needs to be connected to a TV screen via a coaxial cable, so that’s marginally inconvenient to my TV watching family. Somewhere I have a 12″ B&W TV that I originally used for the BBC micro, but I’d have to find that. Also I’d have to get the floppy drive working. My DAD had a 512Kb hard disk, but I’ve never used that….all in all it seems a bit too retro even for a retro project like this.
  2. Use BeebEM – a PC based BBC emulator which I used in the past to play classic BBC games such as Elite. I had a little bit of a fiddle around with this and wrote a few lines of code. However it wasn’t easy to save the code in any kind of text file.

This is a screen shot of BeebEm running on Windows10 PC.

  1. Whilst searching around in BeebEm for something to save the code in a way I can use in other applications, I found BBCSDL a version of BBC basic for the PC ! This website is well worth checking out for a wealth of historical information and has been recently updated. The code window itself features two basic editors and can save the code as ASCII text (my original aim).

So, decision made, I decided to use BBCSDL to produce code.
