I wish. Some of the top layer changes in elections, but it seems like the bad guys in the government have very long careers, alternating between government appointments and jobs in companies closely tied to the government. Cheney is a famous example, but there are thousands more like him.

The culture in this world seems to be quite different from that of startup hubs. These people are suits squared. They fail a lot, but not because they try wildly imaginative things. They fail because succeeding (as we'd measure it) is not their goal; power is.

I assume the person asking the question has good reasons for asking it. If I can I answer. If not, I don't.

Coming to the question proper, there are often good reasons to ask if other people use / don't use a particular technology.

To answer, I use a custom variant of scheme to write machine- learning systems on a cluster of cots machines. It compiles down to optimized C, but I write in scheme.

So for the web I would use PLT and its great web server. In fact I do use it for a little internal app and love being able to write a web app in the 'direct style' ie just write a web page interaction with a user as a function execution. You can just assign a lambda to a link, saying 'when the user clicks this link, execute this lambda'. It's great. However, that links won't be bookmarkable nor indexable by search engines, so if some of your pages need to be, you have to make the links to them be traditional links. So the continuations-based stuff lends itself to the parts of your app that are private to a single user (like taking user input or showing them their email) and/or shouldn't show up in a search engine anyway. This would include anything that you would describe as a 'wizard'.

NASA (or is it just the Air Force?) is using PLT Scheme to control a large telescope in New Mexico (https://hackertimes.com/item?id=75219) to great success. So for soft real-time stuff you should be good. Just from using it, I wouldn't recommend the default garbage collector with PLT for anything like hard real-time stuff. But there are other GCs, so ask around. The PLT mailing list is excellent: http://www.plt-scheme.org/maillist/
