After what seems like approximately three hundred requests that I stop the cheating on fastr, I've finally relented and done something about it. The answer is now sent encrypted, and then your guess is encrypted before comparing with the answer. At the end of the set, if you didn't guess it, the browser sends a "give up" signal back to the server, which gives you the answer in plain text, and sets your score to zero, so you can't "give up" and then submit an answer.
You can still cheat, of course. You can open a second window that's slightly ahead in time, and see pictures before guessing in your first window. Or you can refresh your browser after you know it and get ten points. Or you can "give up" under one name and then submit an answer under a different name. But those are all manual cheats, and I expect you'd get tired of doing that eventually. What you can't do any more (as far as I know, at least) is set up a script to automatically cheat for you.
You also can't make long names with no spaces so that they go outside the designated name box. No one asked for that, but it was annoying me, so I fixed it. And the rounds are now six minutes now, which allows for exactly ten sets of photos, plus a ten second break to look at who won. The last set of your first round might get cut off in the middle, but that shouldn't happen after it gets synched up at the end of a round.
I also pulled all the text into localization files, which will make it much easier to create versions in new languages. But I haven't seen many people playing the other languages, so I'm not sure that's even worth the trouble. I'll let the translation volunteers decide that.
In any case, between these last few fixes and the API, I've managed to delegate (that's the verb form of lazy) most of the future work onto other people. So I don't expect to be spending a lot of time working on fastr now. I think it's about time to call it done and move on to another project.
