The displacement number in rotary engines is quite misleading. The design is so different than a piston based engine that it's not a fair comparison. You're getting more power because you're getting more power strokes per rotation. Because you're getting more power strokes, you're doing more intake strokes (more fuel). So while power/displacement ratio is better, that doesn't necessarily affect the power/fuel ratio at all.

The most important part in my view is that it allows for innovation in the open source graphics world. For instance, NVidia and ATI both make drivers for X.org however neither will produce drivers for Wayland until it gains enough traction. However Wayland will never get widely used until people can actually use it, which requires drivers. Open drivers breaks this stalemate.

And what's this thing about "the engine is only suited for hybrid-electric vehicles, but that's okay. " ... what does THAT mean?

Most likely it means that the engine has terrible spin up/down times and/or is inefficient at doing them. Its best operated at constant speed, generating electricity for an electric motor which actually pushes you forward.

>but until they learn what a compacting garbage collector is Tada! http://www.mono-project.com/Compacting_GC The new GC is bundled with 2.8 and will become the default in 2.10. Mono's VM is pretty nice overall, its the GC that caused pain in long running process scenarios. Its not so much that the GC wasn't compacting either, it was more an issue because it was a conservative scanner which lead to leaks.

>If the padding is invalid, the error message that the sender gets will give him some information about the way that the site's decryption process works.

This is one reason you should send user friendly error messages to your consumers instead of stack traces, stack traces can contain details that an attacker could use against you. It sounds like you're safe if you're following best practices already.

You might not have heard if you have been living under a rock for the past 2 or 3 years, but Android uses the Linux kernel. Whether you can run your _own_ Linux distribution on there is another question entirely. Sooner or later, I'm sure someone will crack it if Samsung has decided to lock it down. As with most (all?) Android devices, you're not forced to use the market.
