Google Wave impressions from a developer point of view

A couple of days ago I finally had my Google Wave sand­box account. Given that I just fin­ished devel­op­ing my very first robot, I thought I’d share some impres­sions on the whole thing. From the user-​side, things are far from being ready. Some impor­tant fea­tures are still miss­ing, just to name one you can’t remove user from a wave once they joined (or, alter­na­tively, there’s no way to ignore a wave). Indeed, given that I joined sev­eral waves to try other people appli­ca­tions, I’m get­ting con­tin­u­ous noti­fi­ca­tions. But anyway, the whole thing is to me like a great devel­op­ment play­ground where I can make all the sorts of experiments.

Google, codejam and number conversions

The dec­i­mal numeral system is com­posed of ten digits, which we rep­re­sent as “0123456789” (the digits in a system are writ­ten from lowest to high­est). Imag­ine you have dis­cov­ered an alien numeral system com­posed of some number of digits, which may or may not be the same as those used in dec­i­mal. For exam­ple, if the alien numeral system were rep­re­sented as “oF8”, then the num­bers one through ten would be (F, 8, Fo, FF, F8, 8o, 8F, 88, Foo, FoF). We would like to be able to work with num­bers in arbi­trary alien sys­tems. More gen­er­ally, we want to be able to con­vert an arbi­trary number that’s writ­ten in one alien system into a second alien system.
