Comment Hydrocarbons does it take to make the Hydrogen? (Score 1) 194

I feel like this just moving the goal posts. Sure I guess you could have some elaborate contraption to make Hydrogen only using solar or wind power, but it's more than likely it was made in a factory that burned lots of hydrocarbons. This is just a way of storing energy. We need to look at the whole picture of where the Hydrogen came from to do a true "full-cost accounting" of the benefits or lack thereof.

Comment Let's just use UTC everywhere (Score 1) 613

The time you go to work, or go home is just a number. I've been a pilot for years and it's very easy to switch to knowing I wake up at 1200 UTC and I usually get home from work about 0000 UTC. What's difficult is all this messing with the clock. If you call a company on the other side of the country, imagine how much easier it would be if they just could give you the UTC time you're use to thinking in terms of for their hours of operations? It really just works, everyone has to just let go of the idea that work starts at 9AM and ends at 5PM. The time your work starts and ends should be a function of where you live around the globe (and perhaps if you work night shift).


Russian Scholar Warns Of US Climate Change Weapon 415

According to Russian political scientist, and conspiracy aficionado Andrei Areshev the high heat, and poor crop yields of Russia, and other Central Asian countries may be the result of a climate weapon created by the US military. From the article: "... Areshev voiced suspicions about the High-Frequency Active Aural Research Program (HAARP), funded by the US Defense Department and the University of Alaska. HAARP, which has long been the target of conspiracy theorists, analyzes the ionosphere and seeks to develop technologies to improve radio communications, surveillance, and missile detection. Areshev writes, however, that its true aim is to create new weapons of mass destruction 'in order to destabilize environmental and agricultural systems in local countries.'"

Comment Light Sport Rules: Very misleading summary (Score 1) 123

The wavier they granted is to allow this aircraft to be consider "light-sport", which means you can fly it with out a third class medical. This is NOT that big a deal and the summary makes it sound like some sort of break-through and that the FAA has held everything up. This just not correct.

The flying car sucks because just like the moped, it doesn't excel at either it's missions. It can never be as good an airplane as one designed just for flying and it can never be a very nice, safe car either. I think goal is home garage to destination in one vehicle while flying above traffic. I think the best hope for that is the CarterCopter ( It's not a car, but it's an affordable, safe aircraft that can take-off and land vertically. The downside, it that these guys have been working for years....and making progress...but they probably have many years still to go, with little funding. The CarterCopter will never out run an airplane in it's same price range, but the vertical T.O. and landing makes up for that.

Comment Anything! Remotely! (Score 1) 945

Why do this Apple fan boys always have to oversell their point. Exaggeration is the best way to destroy your credibility. I could have been fine with "free software movements haven't produced products as compelling as...". That would have been a fine strong statement and something most people could accept, but no. This person had to add "anything" and "remotely". So lame.

Comment Yes to NFS local caching! (Score 2) 341

I found the kernel thread where the original author of the FS-Cache patches, David Howell, makes it clear that on a quiet network with a quite fast server metadata will take longer from the cache. However, at my work we have very busy large NFS servers connected over the building network which is very busy. When you try to read a large file repeatedly in the middle of the day the traditional NFS caching just doesn't work if the time between reads is more than about 5 minutes. I've resorted to manually copying my datasets to /usr/tmp on the local disk and seen huge performance improvements. (this has other serious issues, like getting confused about which copy you just modified and migrating any changes back to the official NFS copy.) I know this feature makes sense for me and others in similar environments. The problem of course is: (1) it will be years before it makes it into RHEL and (2) it won't be turned on by default, (3) my system admins are weary to trying anything kernel-related that's not stock RHEL. However, if I can show them an order of magnitude improvement in speed, which I think this will do, they might think twice.

Comment Re:Great, we get to pay for them again! (Score 1) 224

I'm even more confused two of the GPS patents have my name on them. I didn't want to patent them (for the same reasons you state), but NASA management pushed me into doing it and now they're selling them, where does that leave me? What if I use some of the concepts in our GPL'd OpenSource GPS receiver? Would I have to pay for my own ideas back? This is why I left NASA and told them so in my exit interview.
