• Delphi/Pascal training in high school/college/university

  - by Bruce McGee

  Are Delphi/Pascal being taught in any high schools/colleges/universities, particularly in Canada and the US? I was surprised how many schools in the UK are teaching Delphi. Their largest exam board is even dropping PHP/C#/C in 2011 and encouraging Delphi. I also remember that CodeGear was going to provide development tool licenses to Russian schools a couple of years ago. I'd like to know if it's being taught closer to (my) home.

• UI Code Level Patterns?

  - by DTS

  Is there a book or some other online resource that covers common code-level UI patterns (not widgets/components per se) and idioms. I'm looking for a resource that goes into some depth on MVC, event models, delegates, etc. Something in a similar vein to the POSA series would be excellent. I'm looking for something that is as platform-agnostic as possible, but I'm not sure if that even IS possible.

• High-Quality Text-To-Speech engine for personal use

  - by phihag

  I'm looking for a high-quality TTS engine that I can afford (let's say less than 1000$). So far, I've tried flite and festival. However, while the results are certainly understandable, technical texts are hard to follow. Commercial TTS solutions from Loquendo and Readspeaker sound way better. However, these companies don't seem to be willing to sell their product to mere mortals - I can't find a price on either's homepage. So, what are good TTS solutions for personal use?

• Content controls have to be top-level controls

  - by horatio

  I have a website that can be accessed from www.blahblah.com and special.blahblah.com. The www site always works but occasionly I get a 'Content controls have to be top-level controls in a content page or a nested master page that references a master page' error on the special site. It's exactly the same code running in both situations and the offending page doesn't even have a master page. Why would it work all the time on one and fail sometimes on the other?
