Comment what is OpenStack? (Score 2) 42

The summary does not tell me what this thing, apparently popular in Beijing, actually is! You could at least link their website. :)

Anyway, looking at their website, it looks like it's a "cloud operating system", i.e. infrastructure for managing a cluster in a virtualized, "cloud-like" way. Does anyone know how it compares to other such platforms, like Eucalyptus and the confusingly-similar-in-name CloudStack?

Comment Re:And what's that in metric? (Score 2) 353

But when you say "goes 10x further per [unit fuel]" you're talking about it the other way! I.e. this one gets 110 km/L, 10 times more km per liter than your car that gets around 11 km/L.

If instead you're comparing 9 L/100km to 0.9 L/100km, that's not talking about how much distance you get per liter, but about how many liters you use per distance, i.e. the rate of fuel consumption. Of course, they're equivalent ratios; it's just a reciprocal.

Which of the two widely used metric standards do you want? ;-)

If you're from one of the countries that uses the km/L measure (Netherlands, Denmark, Japan, Korea, etc.), then this Volkswagen prototype gets about 110 km/L.

If you're from one of the countries that uses the L/100km measure (Germany, Italy, Australia, etc.), then this prototype uses about 0.90 L/100km.

Digging around, they do also seem to be working on a transport-level protocol with some of the main features of SPDY (fast multiplexed encrypted streams), called QUIC: http://en.wikipedia.org/wiki/QUIC

That feels like a better solution than shoving it into HTTP. But I guess if they want quick adoption, it's a lot easier to upgrade the application layer than the transport layer. Especially if you're Google and control both ends of the application (several widely used servers and a widely used browser), but not the networking equipment in between. So I can see why, pragmatically, they would be pushing HTTP/2.0.

Comment Re:Flat structures never, ever happen (Score 2) 224

I agree structurelessness is problematic, but there are structures that work which are less hierarchical than traditional boss-and-subordinates tree-styled management structures. A common feature of Scandinavian workplaces, for example, is a set of committees with precisely specified areas of competence. It is relatively non-hierarchical but very structured and transparent: rather than informal cliques taking on different roles, formal committees with procedures take them on. Overall it works pretty well.
