  1. Re:Use this as a launch vehicle??? on Ballooning into Space · · Score: 2

    SPECULATION WARNING!!!

    OK. No maths behind this either but... Hydrogen under atmospheric pressure is not a great fuel in terms of rocket boosting. So we need to do something to put some pressure into that baloon - but remember, the more pressure the more density the less bouancy so the less lift - so we need to apply the pressure once we're up there.

    We also need to apply it quickly - so we dont drop like a stone.

    We also need some oxygen to burn with the H2 - not much of that up there... so we need to carry that too. Unless...

    Unless we don't bother burning it we just 'untie the balloon' and let the H2 squirt out in a controlled manner...

    We'll have 1 atmosphere pressure in the balloon, and 1/10th atmosphere outside so we have 9/10 atmosphere of pressure. So we need to work out the thrust that that can be turned into.

    This is useless, but I'll post anyway in the good slashdot tradition!

  3. Health Issues on Using Radiators to Cool CPUs · · Score: 5, Informative

    There is a documented link between low level noise and hearing and stress levels in those spending long times exposed to them.

    The hum of a fan, whatever it is cooling, is often at a level that you might strain to hear clearly. It is these levels that can cause hearing strain. This is similar to eye strain when you need glasses and can give you monster headaches.

    Many articles in New Scientist, among others, have covered this - normally relating to office environments.

    Symptoms can be migranes, and a persistant ringing / humming sound when you are in a silent room / trying to sleep. Its worth checking out if you feel any of these because the long term stress levels can be harmful.

    I don't know if its a problem for babies - but I know the effects are magnified many fold if you are exposed for long periods, i.e. all night. So I wouldn't leave the machine on 24/7 even if the baby doesn't seem bothered by it 'just in case'.

  4. Not really a fuel. on The (Possible) Future of Alternative Energy · · Score: 3, Insightful

    Hydrogen is not really a fuel as such, in the way that Oil, Gas or Wood are fuels - because you have to use some other fuel to produce it.

    Hydrogen is best thought of as a way to transport energy to places where you can't make it on the spot efficiently, or in sufficient quantities.

    For example, the average suburban house has enough sunlight and wind to cater for all its energy needs. If we make solar and wind capture more efficient, every garage could have a small 'charger' cracking Hydrogen and storing it for the car.

    A similar idea is being researched for Mars projects (using CO and O2, but the same principle). This allows an ongoing process (powered by the sun for the martian experiment) to generate useful amounts of transportable 'fuel'.

    By turning the energy model on its head, away from the current 'few big power stations' model to 'millions of tiny power stations' model we not only get better efficiency but less polluting powerstations because they are in EVERYONES back yard.

    Hydrogen has a role to play, so might CO. But this is no fuel of the future - the fuel of the future is the sun and the wind.

    If you find a job you love you'll never work another day in your life!

    Bollocks! I loved my job 3 years ago, then about a year ago it started to get me down, it was mundane. It was all the things you express here.

    So I quit, and did something else. I started a company with what little money I had so that I could do smaller jobs, for varied clients, keeping the interest alive. I could just have easily taken a different job, or gone back to school - the point is I CHANGED.

    It worked, its fun again, now that the worst of the financial worries are (touch wood) over. I'm back to having a job I love.

    The truth is that you need to find a job you love every couple of years - or just accept that your days will be spent grunting along with the rest of them, while at night! at night you turn into the mega world changing shag fest that you always wanted to be.

    So stop NOW, dont even finish the year - pick something else and do THAT. NOW. TODAY, well - take the weekend to think it over then do it on Monday!

    If I have to pay for TV thats fine - but I shouldn't have to pay AND watch commercials AND have product placement AND have all the shows sponsored by something AND have a stupid logo burning a whole in my screen.

  7. USP on Athlon XP1900+ -- Faster Than A 2GHz P4? · · Score: 2

    Indeed. AMD need a clear message to send out to people.

    "60% the cost, 90% the performance"

    Pretty much as fast, a heapload cheaper. They are not going to be 'the fastest' long term in the foreseeable, but they ARE pretty much up there now.

    If I bought a PIII 600 or 700 back a while it makes NO difference now, they are both old machines way behind the curve. 20%, even 30% better performance is only desirable at the time. Pretty soon the machines are seen as roughly equivalent as they both start to offer less than half the performance of new machines.

    The problem with globalisation, or capitalisation, or anything is that people do not apply common sense when purchasing.

    When I buy a bag of coffee grounds I automatically go for the fairtrade bag as I know the grower gets more money than the Kenco bag.

    When I buy apples I buy British ones, not South African, as it makes no sense, to me, to kart apples half way round the world when we grow perfectly good ones at home.

    When I buy clothes I try to establish where they were made before buying - and buy only from reputable manufacturers.

    I'm not saying this is easy, theres not a label on Nikes saying 'sweat shop and child labour likely used to make these', but come on, if we don't buy the products the practices don't make them money.

    I subscribe to New Scientist and a few other general science journals, which have articles on this sort of thing from time to time. Being on paper I can't dig out references too quickly.

    My first proper PC to live in the lounge was a VERY noisy P100. What I did, and what I'd suggest, was build a cabinet around the machine and lag it with soundproofing foam (or bubble wrap - works just about as well - just looks dodgy).

    Its not perfect, but it cuts down on noise amazingly. Just make sure you have vents on the back of the box for airflow so you don't burn your house down when the thing overheats.

    I'm sitting at work typing this, before everyone else gets in, and the hum is awful if I turn off the tunes.

    Don't quote me on this, but I THINK 'noise holidays' can be important. i.e. if your at your machine 14 hours a day 6/7 days a week that is MANY times worse for you than 7 hours a day 5 days a week. And even an hour of proper silence can greatly reduce stress levels - thats not peculiar to low level noise, thats true of everyone, and it works great - you feel fantastic after an hour in a quiet room - awake.

    Stress levels associated with low level background sounds are shocking. It can have real physical effects on your heart etc...

    If you work in a quiet environment and you hear a humming noise constantly then PUT THE RADIO ON or something. This will drown out the lower level noise with something your brain can understand and filter out. If you don't hear anything your either deaf, or your brain is doing a good filter job.

    The scenario is roughly analagous to tinitus, though usually not as serious, where your brain is struggling to make sense of the white noise and 'strains itself'. You end up in a constant state of low level panic because you don't know what is happenning around you.

    Seriously dudes - fan noise, the new RSI!

  18. Suggested Change to IP Laws on Ultima Revived · · Score: 3, Interesting

    While IP laws are intended to protect the holder, there is a good arguement for changes to protect the consumers interests.

    Wherever a significant consumer group is NOT being served by an IP holder there should be a legal process by which the IP defaults AWAY from the holder following a period of non-exploitation.

    Scenario: Publisher X withdraws GameX from the market, and stops supporting players. A player registers this fact with a register for a small fee (call it $30, just to stop the jokers, to make sure it matters). Following a period, perhaps 2 years, if the company has made no significant moves to make the IP available to the paying public it defaults out to the public domain. Simple.

    Company X will argue that it could be working on the new version during those 2 years and this sucks. But, any decent games company will continue to support its user base while the new game is coming along - drip feeding us patches, upgrade packs, new terrains.

    Similarly, any other software that starts to die could be openned up after a couple of years of non-exploitation or when the company went bust. Doesn't mean they have to release the code - just that they cant sue your arse if you copy them / take inspiration.

    Sony should bundle the original PS with all their kit, DVD players, TiVos, anything that points at a TV. Put a handful of PS games on a few DVDs and away you go!
