Citations? Here're mine:

USA uses about 1500 m3/capita/year, which is similar to New Zealand (1200 m3/capita/year) and Canada (1400 m3/capita/year). Compare with California alone, we're at 178 gallons/capita/day which is 245 m3/capita/year. That's lower than most countries.

I'm (reasonably) sure that number the 178 gallons/person/day figure is the "urban" per-capita, not the per-capita of the entire state.

The state's per-capita water use is more like 1390 gallons/person/day.

So you disagree with the patent system, but yet you have some software patents and you want to try to wield them to extract extra money from a potential employer.

It doesn't actually sound like you disagree with the patent system at all.

If you want to do the ethically right thing, don't buy yourself in any deeper. Don't bring them up to your employer, and don't try to charge them extra money when you write code for them that uses the math concepts that you've hoarded for yourself.

VxWorks?

VxWorks is a great product. It's also waaaayyy outside of the price range of a hobbyist developer. Getting up and running with the VxWorks suite of tools can easily cost 20k (USD), and the recurring license fees are pretty significant as well. I would also bet that auditing the VxWorks source code (or trying to get custom patches in) would cost significantly more.

As an embedded-systems guy, I'd _love_ to have a Unix-like where I could schedule events that were guaranteed-by-design to fire within some deadline of when they were scheduled. Then I could host my once-per-kHz hardware service routines on the same processor that was also running my device's web-server.

Minix's microkernel architecture seems like an ideal fit for that kind of use case. If there are any Minix devs reading this thread, how easy would it be for me to make a system like that using Minix?

I would completely support Google Glass on police if (and only if) there are penalties to the participating police departments for 'accidentally' losing the footage or having a 'malfunction'. These two things both sem to happen at a shocking rate whenever a policeman is accused of misconduct.

No comment on whether or not the state of Jefferson would ever be able to support itself without the rest of California, but Tim Draper didn't pull that particular state out of the ether. I have some parents that used to live up in North State, and the hill folk there love the idea of Jefferson.

They even have a website: http://www.jeffersonstate.com/

The moon is pretty dry. If if this is supposed to be some proof-of-concept for growing food in a lunar base/colony, don't they need to address the larger issue of where such a garden would get its water?

If we have to transport the water to the moon as well as all of the raw materials (dirt, plant nutrients), what possible savings could there be against just stocking a base with MREs?

I'm not sure what to use to replace Make though. I'm a Python guy so I would probably want Scons or something like that, but Ruby fans probably want Rake, Java fans probably want Ant, and in general I don't think there is any consensus on what might be the best replacement for Make

I went back and forth on different Pythonic build tools for awhile. Scons is pretty great if you're doing 'standard' sorts of builds, but I found it a little heavy for my tastes and really hard to customize to my tool flow (in FPGA land, there are all kinds of nonstandard vendor tools that all need to play together).

I've been using doit more and more over the past few months, and I'm continually impressed by the tool (aside from the goofy name). It works amazingly well for automating tricky/exotic build processes.

Why is it that whenever people talk about how this-or-that stock market action has "cost investors millions"? It's not like the money was lit on fire. It either never existed in the first place, or somebody won big off of somebody else's poor decisions. Isn't stock trading a zero-sum game by definition?

+ - Energy efficiency gains failing to keep pace with Internet's growth->

Submitted by terrancem
terrancem writes: Energy efficiency gains are failing to keep pace with the Internet's rapid rate of expansion, says a new paper published in the journal Science. Noting that the world's data centers already consume 270 terawatt hours and Internet traffic volume is doubling every three years, Diego Reforgiato Recupero of the University of Catania argues for prioritizing energy efficiency in the design of devices, networks, data centers, and software development. Recupero highlights two approaches for improving efficiency: smart standby and dynamic frequency scaling or CPU throttling.
