"A multithreaded file system is only a performance hack. When there is only one job active, the normal case on a small PC, it buys you nothing and adds complexity to the code. On machines fast enough to support multiple users, you probably have enough buffer cache to insure a hit cache hit rate, in which case multithreading also buys you nothing." - Andy Tanenbaum on the "LINUX is obsolete" Thread from 30 Jan '92

Nice to see a so called "expert" so far off. Seriously, not the first CS Professor to be completely backwards. I've met a few of those too. :-)

Just like most of the Emirates, Dubai is a Disneyland. Only bigger.

Seriously, I don't know what crack these bedus are smoking, but there are more books translated into spanish each year than into any language of the emirates in the past 100 years. These people base huge chunks of their view of the world on an ancient facist monotheistic religion, live in societies that by social structure resemble the grimmest of dark ages, sharia law and all, and all they have is truckloads of money from selling their oil and no real idea what to do with it other than squander obscene amounts of resources to build a huge disneyland out in the desert. The amounts of water wasted alone are beyond imagination.

I'd have no problem with building a high-tech nation within a few years, if I'd actually be seeing some real progress, but I don't. I'm seriously sceptical of Dubai and its likes gaining critical mass and actually building sustainable societies

The prince of Dubai would be well advised to use all that money of his of building universities, implementing basic human rights and getting a modern society going and perhaps building a modern armed force to defend it. Since it doesn't look that way, I'm not placing my bets to high on this whole Dubai thing.

I wouldn't be suprised if this all collapses within 20 years and we have a bunch of impressive ruins but nothing more.

My 2 cents.

Yeah, now if I want to listen or watch something that isn't 6 months old or less my options are either buy it if it is even available or not hear/see it. Boy did we show those dinosaurs, AmIRight?

Which is why when you read you don't have to care if it is a tab and three spaces, two short tabs or 8 spaces. Using a non-visible character for control is just a bad idea. And don't even get me started on code clarity - what I find clear to read vs what you do vs what a compiler demands - ICK! To put it into web terms, go try posting something about how the new (place your browser here) is going to impose its manufacture's CSS on every page, ignoring the user's css prefs, hell even ignoring the page authors css and see what kind of firestorm you light off, and with good reason. Code should be no different. Especially when it comes to white space as commands.

As far as amateurs, the barrier to entry for programming is far less than for working with electricity. Which requires more training - writing an Apple Store app, or safely changing out the breaker box in your basement?

Changing out your breaker box. Hands down. There is no arcana, English as a language, no IDE, no security, no graphics to work out, no logic. You almost can't buy the wrong materials, and if you actually ask the guy at the store you won't and after that it is pretty much tab A, slot B, kind of work. It is so easy that most munis don't require that a licensed electrician do the work. Oh, and for the small fee to the city you have to pay for the permit theey have a guy come out to inspect the work to make sure you didn't screw up.

I am a programmer and I have a vague idea where to start with making an app for iOS, but specifics? It would take me longer to dig them up than driving down to the local hardware store to buy a breaker box and some fuses. In short, you posted as if electrical work was "a vocation requiring rare talents, grueling training, and total dedication" while trying to down play programming. I agree that programming really isn't that hard, but there is a reason programmers get paid what they do.

Given the disconnects between the documentation and actual operation, it is a bad thing. At least that's true for Fedora's take on systemd. I tried to come up with a work-alike of a System V set-up script, and found some issues. Yes, I posted a bug report. No, nothing has happened with that bug report.

We'll see if Centos/RHEL did a better documentation job.

Anyone who says that climate isn't changing has their head in the dry dirt of the Oklahoma Dust Bowl. Recorded history shows clearly that there is climate changes over time. Indeed, climate shifts have influenced man's history more than any other single event source. Scientific evidence shows that climate changes constantly. The problem I have is the intensity which climate cultists point to humans as the cause.

Given that the magnetic poles have been shifting regularly, if slowly, means that the solar wind's interaction with the Earth will change as the magnetic field moves. ("Settled science"? I haven't heard any nay-sayers.) How about the argument that carbon dioxide has been "building up"? Yet one study I finally found, that looks at wider time periods than a century (http://www.biocab.org/carbon_dioxide_geological_timescale.html) suggests that (1) temperature has no significant correlation with CO-2 content, and that we are coming out of a period of low CO-2 concentrations.

Does this mean that man is completely blameless? No. Temperature is a function of released energy, and the Earth had stored sunlight for millions of years. We are releasing that stored sunlight at an increasing pace, which eventually ends up in the atmosphere, one way or another, as heat. How much is due to technology, and how much is a by-product of man's actions such as the clear-cutting of Amazon rain forests and covering the land masses with asphalt and concrete, and how much is caused by other, non-man-made changes? So the question is whether the existing natural system for expelling heat are up to the task. More importantly, details are important. How much heat does technology dump into the atmosphere? Clear-cutting (and clear-burning) of land? Other sources? Without numbers, everything is just opinion. And when it comes to such "science", one option is equally as good as another, absent accurate and provable forecasts -- I believe that is why the climage deniers hold to their beliefs. Cultists haven't proven their case, or even shown their case has merit.

Are there other solutions than those proposed by the client cultists? One way to keep heat out of the atmosphere, if that is the goal, is to keep sunlight reaching ground level from being converted to heat in the atmosphere. Photovoltaics can help, although the energy would be released -- just perhaps in a different spot or a different time; the benefit would that such energy would displace energy released from fossil fuels -- current sunlight instead of ancient sunlight. Ditto solar thermal power plants -- using today's energy instead of million-year-old energy.

Sunlight that never reaches the ground can't contribute much to the heat load. How about reflection and dispersion? Some of the energy would be converted to heat by the air itself, but the rest would escape into space in the form of radiation (light, infrared). Another way to trap sunlight so it doesn't contribute heat is to increase the surface area of leaves, to increase photosynthesis -- and that has the benefit of eating up CO-2 as well as keeping heat out of the air. (Cultists: when did you re-roof your homes with grass? It would lower your air-conditioning bills, too, by keeping the heat out of your attic.)

But is that all there is? There is considerable heat trapped in the core of our planet. Further, there are energy sources in the ground that contribute to the atmospheric heat load...but I never see that heat source mentioned in the Climate Cultist literature. What is the effect of volcanos on the solar balance sheet? We know that ash can bring down airplanes, but what is the effect of that ash in the air? It could well be that geothermal power generation, replacing fossil-fuel generation, would be an excellent way to keep the atmosphere in thermal balance. Don't hear much about geothermal from climage cultists, do you...

I was part of the generation that "grew up with the Bomb" -- and I remember all those discussions about "nuclear winter" that would be brought on by The Ultimate War. Block enough sunlight, and you drop world temperature. But you won't like the side effects.

And so I come to the end of my thoughts on the subject. If you have faith that we "need to do something" about the problem, show us your work, your accurate predictions of change, your proofs. Instead of trying to make us "believers" by trying to evangelize your faith, show something that can be vetted by the scientific method.
