...but the Planetarium closed down a few years ago. It was turned into a "celebrity cinema" bit of Madame Tussauds, showing showbiz movies. Philistines.

However, the Greenwich Observatory has their own, new planetarium - it's brand new, and right by the Greenwich Meridian:

I've got two systems setup (home and work):

Home:
A Mac Pro (could just as well use a Windows PC, but this is my home server) running iTunes. AirPort Express with AirTunes units in my bedroom, office and kitchen, with powered speakers attached to each. AppleTV (ehem - "enhanced", of course - http://wiki.awkwardtv.org/wiki/) in my lounge, hooked up to the TV and hi-fi. I use an iPhone or iPod Touch with the Remote app to control it, and it works great. You could get more functionality with a Sonos setup, but I already had the server and AppleTV, so it only cost me about $70 with eBay AirTunes units.

Office:
A VM running on our office server with Squeezebox Server, serving the tunes. A mixture of Squeezebox devices and PCs running the software player throughout the office. A whole load of apps and web interfaces to control the server, and the multiple streams coming out of it. With the exception of the Squeezebox hardware, it was free to setup, and you don't even really need those if you're happy to use spare PCs.

By and large, both arrangements work well - the aim was to have systems that we could just setup and forget about, and save the odd server reboot, that's what we've got.

My company (for upwards of 10 years) has been using:

• An SVN (Subversion) server on our dev box
• Developer or group specific subdomains in IIS / Apache on the dev server, to which working copies are checked-out
• Deployment to live servers via SVN checkout when the time comes
• Global variables to check which server the app's running on, and to switch between DB connection strings etc.

Still not figured out an efficient way to version MSSQL and MySQL databases using OSS, though. Open to suggestions!

The same marketing people I can hear saying the above in my head did, honestly, suggest we "should be getting into Second Life" some years ago, but they were reluctantly dissuaded. A narrow escape for my development team, I think.

"This Twitter thing, yeah, it's all, like, Web Two Point Oh, and customer synergy interaction right, and then people can, like, interact with their data and it'll be all like, in the Cloud! Yeah!"

I can guarantee something very much like the above took place in their marketing department shortly before this was built. I've spent 10 years listening to this from marketing geeks - nothing more dangerous than a new technology half-understood.

The interface uses two words: one which is verified and one which isn't. Assuming the first one is typed in correctly, they present the second to a bunch of people until they get a consensus (three the same, I think) and then it goes in the "verified" pile. Thus, even if the second word's not verified yet, a spammer will still get caught out by the other one.
