  2. Re:The lack of FLASH is a PR-Stunt! on The iPad Questions Apple Won't Answer · · Score: 1

    No, flash is never coming to the iPad/iPhone. It's just not in Apple's interest to have a large chunk of code on there they have no control over.

    Apple are pushing html5 and the app store as alternatives and it looks like it'll work out well for them. I'm more inclined to think flash is in trouble: the html5 video players are already better than the flash ones (seeking works! cpu use is way down! they don't stutter! they are easier to develop! you can right-click and save streams!) and that trend is only going to accelerate. Heh, especially if they fix the fullscreen thing.

    Once flash loses the video player market (I guess it'll stay as a fallback for a while though) it becomes a lot less important.

  3. Your claim is crazy on Russians Claim More Climate Data Was Manipulated · · Score: 1

    the "scientists" are [cooking the data] for a variety of reasons which boil down to the age old canards of money or religion.

    That just seems like an insane thing to say. I can't believe you are a scientist or know many scientists.

    In my experience (I'm a working scientist, though not in climate), science is very, very competitive. Just brutal, in fact. It's full of mildly Aspergers people who delight in other's discomfort and are convinced (almost) all other researchers are idiots. If you have a clever idea that cuts your rival's work off at the knees, by God, you're going to publish, and you're going to rub their face in it as you do.

    I find it impossible to believe that good anti-AWG ideas really have been suppressed for 50 years or however long it is.

  6. You are not correct on The Science Credibility Bubble · · Score: 2, Insightful

    In 1975, American Scientist, Nature, and New York Times were publishing story after story about the imminent New Ice Age that would plunge the world into subfreezing temperatures for the next 100 years.

    That's not true, please check your sources again. Some pop sci pieces on the subject appeared, but no serious scientist ever claimed that a new Ice Age was imminent.

    You can read about the history of the 1970s global cooling scare on wikipedia: http://en.wikipedia.org/wiki/Global_cooling

    Here's Newsweek talking about its own coverage of the issue, and quoting William Connolley:

    The point to remember, says Connolley, is that predictions of global cooling never approached the kind of widespread scientific consensus that supports the greenhouse effect today.

    From http://www.newsweek.com/id/72481

    And finally here's Connolley himself:

    Was an imminent Ice Age predicted in the '70's? No. If you can find me a reference saying otherwise, I'll put it here.

  7. Re:Nvidia 8800GT PS3 on US Government Using PS3s To Break Encryption · · Score: 1

    I can't find any single-precision performance numbers for a modern cpu, but I'd bet that they easily outclass PS3s too.

    It depends on the benchmark. The IBM whitepapers on the Cell have a matrix multiplication program which (after quite a bit of tuning) went just over 200 gflops. A Core2Duo has a theoretical peak of about 15 gflops.

    Of course the C2D will be much faster than the Cell with most general programs, but with math that parallelises well and that you spend some time hand-tuning, the Cell can be very quick.

    Finally, the built-in channel mechanism is something that can be done in C++ in less than 100 lines of code.

    Yeah, and all of your packets have to go through said remote service as well. If said remote service is hosted in another country, guess how much higher your latency is going to be?

    That's not how it works. The central server does matchmaking, but that's about all. The game itself is hosted by one of the clients, with some magic to hand over hosting as clients enter and leave the game. Your game packets do not go through a central server.

    Firstly, I did not say Ubuntu. I said CentOS.

    But no granny would ever use CentOS. It's not a consumer-oriented linux at all. In Ubuntu, you have 30,000 packages all nicely indexed with sensible descriptions. I've never had a package install fail in 5 years of use. Click Add/Remove and you can find stuff easily, with a star rating system too.

    There are no stores that sell Linux programs. No online appstores.

    Canonical's AppCenter launches in a couple of weeks, though it's just the same thing they had before but with a nicer GUI. Perhaps it'll encourage commercial software, we'll have to wait and see I guess.

    Linux UI's are not always "laughably easy to use".

    Hehe ya got me there, that's certainly true. But installing software is far easier than Windows or Mac.

    They didn't say GIMP was better, they said that that was the argument you would need to be able to make to convince someone that FOSS was worthwhile.

    I'm not sure your GIMP criticisms are very good either. PS does not even offer scripting as far as I know, and GIMP keeps its file-format unsupported for a reason. And how is a major new version every year stagnating?

  19. simple explanation of AGW for you on Global Warming To Be Put On Trial? · · Score: 2, Interesting

    Here's a very simple explanation of AGW for you. No computer models, nothing about weather, very basic.

    Imagine a sphere the size of the earth at the earth's distance from the sun with the earth's albedo (average reflectance). What will the surface temperature be due to solar radiation? Do the maths and you get a temperature about 33C lower than that we observe on the earth's surface today. In other words, the earth's atmosphere acts as a blanket trapping heat and raising the temperature by about 33C: the greenhouse effect.

    What parts of the atmosphere are responsible for this 33C increase? By far the most important is water. As a gas and in clouds, it is responsible for up to about 90% of the effect. The remaining warming is caused by the so-called greenhouse gasses: CO2, Methane, O3, NO, etc.

    If you examine the absorption spectra of these gasses and weight by atmospheric concentration, you'll find about 40% is due to CO2. So 40% of 10% of 33C is around 1.3C of warming due to atmospheric CO2.

    Atmospheric CO2 has gone up by 50% since pre-industrial times, the increase is almost all due to fossil-fuel burning (you can tell from radioisotope ratios), so we would expect about a 0.5C rise in global temperatures due to human CO2 output.

    Of course that's a very, very crude back-of-the-napkin calculation, but the result is approximately in line with the IPCC reports. Here's another version of the same calculation (but a bit more complex), with full references and some spreadsheets you can download and try out yourself:
