Alas, there is no free PL/I compiler for Windows or Linux; certainly not one with anything approaching a full feature set and currently maintained. I learned PL/I at technical college in the 1980s and it was certainly better than the other languages taught then (COBOL, BASIC and RPG). I would like to be able to write a few programs in it for nostalgic reasons.

If you want to play with a free compiler, try OpenCOBOL at http://www.opencobol.org/.
There is a list of other free COBOL compilers at http://mainframewizard.com/content/free-cobol-compilers but some of them look pretty old.
I don't think we were taught anything about computers in class, but there was a computer programming club. We used PORTRAN, which is a cut-down version of FORTRAN - I think it stands for Port-a-punch FORTRAN. The cards were sent away to a computer a few hundred km away, and a syntax error listing came back by the following week. It wasn't exactly a productive environment, so we competed to see who could get the most different errors in a single program.
Far more countries than that involved. Namibia, Botswana, Mozambique, Kenya, Zambia, Mauritius and Madagascar will all have dishes too.
Those of us who grew up in areas where there was no electricity. Even in developed nations, electricity wasn't available in some country areas well into the 1960s. In my case, this was Northern Ireland, only a mile or two out from a small city.
New Scientist is possibly the best popular science magazine available. Scientific American is pretty good too, but doesn't have the same coverage because it's monthly, while NS is weekly.
The original Ghost is still produced as Ghost Solution Suite. See http://www.symantec.com/business/ghost-solution-suite. Symantec also produces Norton Ghost which uses a different code base and incompatible image file formats.
How could you want to live anywhere other than the place which is the first developed country to see the sunrise every day? (http://en.wikipedia.org/wiki/NZST) I understand if you would rather live in the Chatham Islands (45 minutes earlier still), or Kiribati (an hour earlier), but New Zealand has some advantages in comfort and lifestyle.
You think more than 5 jobs in a lifetime is unstable? I've had about 5 different careers, and I'm only just into my 50s. If you don't change directions occasionally, you get stuck in a rut.
