The website exists for more than 3 years, today we are the 7th of October and the donations are already at 100% for the whole month. It's arguably sustainable enough.
On a quick glance, I didn't even find a donation button. In fact, I found none, even after clicking through the menus (google sent me here: http://de.lichess.org/donate ).
Traceur (ES6 compiler) itself has a runtime of several hundreds kb. Nothing you can't avoid at some point. There is an overhead for sure. But in most cases, execution time is spent in native calls (Dom rendering especially).
Hm, the reactive manifesto doesn't say that it's new. It tries to convert people from bloated ol' Java/CSharp to better practices that fits new common needs. Of course Reactive is not new... Nor realtime... But an ecommerce website for instance never had to wonder about this kind of things before: new needs.
It is not just about Java bloatware, it is already obvious that it is crap and several "fixes", notably Scala and Clojure, are already matured. It is mostly about understanding and avoiding other broken by design things, such as thread-mutex based "concurrency", mutable, non-parallel collections, and imperative programming (all these Java loops which do mutations) in general. It is about ideas summarized by Joe Armstrong in his thesis, that the world is parallel and that actor model and share nothing architecture together with fault tolerance and message passing via unreliable channels as the only way of communication coul is a more appropriate paradigm than current imperative-pthread-mutex mess.
Also, I was under the impression that coolant does not boil at that high a temperature at standard pressure. The point of the sealed coolant system is to increase the pressure and hence the boiling point, but if it boiled at that temperature by default that would be unnecessary since no engine runs that hot.
Yup, but we can 868MHz in Europe, and with all the support from international backers I think we may end up doing that as a stretch goal! Just have to talk it our with our RF expert, which we're doing!
