  1. windows binary compatibility? on Indian Military Organization To Develop Its Own OS · · Score: 1

    there is several projects aimed at running windows binaries, one of them being an NT clone, dos clones already exist and can be made to run windows dll's on top for an olde worlde windows, and of course wine. i personally hope what it will involve is a bsd core running a customised and advanced wine fork, i mean, considering brazil and several other countries are going linux and open source it would be stupid of them to not collaborate with their fellow rising industrial stars like brazil who iirc are moving their government IT over to open source. a 99.9% binary compatible framework to run windows apps would be beneficial for everyone who is not NATO, indeed i can imagine some of the more client-agnostic big tech contractors who help build military stuff would love to be able to sell their windows-targeted software to someone else... brazil, india and russia at least would all be interested, china is too closed to alliances in any way but who knows, if india gets their project off the ground and achieve their goal.

    remember, a lot of those windows programs are now partially developed by indians... if anyone can make a fully binary compatible windows environment, it's india. they've been doing so much of american-based multinational corporations' development already they have a rich developer skills base.

  16. Re:water on Thermosphere Contraction Puzzles Scientists · · Score: 1

    i think it does count. the extra heat from global warming is sequestered as latent heat by extra water going into the atmosphere which means less evaporation and if the amount of carbon dioxide being produced to power an average person's life needs is in the tonnes then we are talking about tonnes of water being released into the atmosphere too.

    i am not questioning the importance of carbon dioxide's effects, simply that the topic in question, the shrinking of the thermosphere, could be explained by the rise in available water that is soaking up the excess heat, and that the thing that this shrinkage implies to me - rising atmospheric density, is an effect that only water can possibly explain, and has effects on the radiation reaching the surface that i've not seen discussed. increased refractive index of the atmosphere, for one. this could probably be measured too, with adequately sensitive devices.

    i know that carbon dioxide is also a dense gas, but heat combined with increased available water in gas form is a factor in the equation. also, and you are not considering this, but precipitation does not always occur when temperature drops below the dew point, this is what cloud seeding is all about - just like crystals falling out of supersaturated solution, without seeding nuclei that water stays in gas form.

    it seems logical to me that increased atmospheric water is going to mean a rise in atmospheric density (possibly also increasing total internal reflection and reflection) and obviously also a lowering of overall temperature in the atmosphere (more water in the atmosphere means a higher latent heat capacity). increased density means more effect of gravity, as well as the overall drop in ambient temperature from increased heat latency.

    i'm not sure what other effects there would be from increased atmospheric water, as well as increased CO2 and reduced O2. i was thinking it may influence cloud formation patterns, alter the amount of overall radiation striking the poles and equator (via total internal reflection caused by increased atmospheric refractive index).

    in any case, i'm not that familiar with climate modelling and i'm not sure how much they count the increase in H2O in the atmosphere in their predictions, but it seems to me if we are gonna go out hunting for human influences on climate changes, then the influence of water should be, in my view, rated more highly than any other factor because of the refractive index and latent heat capacity of water, two factors that are naturally going to give it the strongest influence of any chemical in the air.

    prohibition drives drug production and distribution into the general criminal millieu (just like in al capone's days) and anything we see as a negative side of drug abuse is amplified by such things as fluctuating purity, contamination, the crime committed by addicts to pay the inflated prices justified by prohibition, not to mention the fact that any genuine research about drugs is gonna be difficult to do when the people funding it are probably looking to see 'drugs are bad' in the conclusions of the studies.

    also this point needs to be talked about:

    Here is an example of a legal drug causing lots of problems. Do we really need to multiply that? Alcohol and pot are baby aspirin compared to coke, meth, heroin.

    what basis is there for the idea that legalisation is going to increase drug use rates? surely the people who want to use drugs are already using them, and the only thing that will change is the ones who were using legal ones may decide to spend their money on ones that used to be illegal.

    your statement is based on the unfounded faith in the idea that prohibition is actually reducing drug use. if you look at the epidemiology of drug use, interestingly enough you find in places where the law is soft on prohibiting the less harmful drugs (eg, cannabis and the netherlands) that they actually have lower drug use rates and lower crime rates.

    prohibition is like the mother of drug advertisments. by banning a drug you make it into a forbidden fruit and just like the old myth of adam and eve and the serpent and the fruit of knowledge, and half the population is going to use it JUST because it's forbidden. prohibition gives a very dangerous avenue for the outlet of the urge to defy society that the majority of the population experiences in a big way during their teenage years.

    even with drugs that are ostensibly legal, like tobacco, for example, the overall poor opinion of it creates a hook for the young ones and this is why we are seeing that rates of taking up smoking in young people hasn't significantly changed even though advertising has been banned, i believe actually in some places it's increased.

    Soo ... you're saying that a lack of legally available meth is the problem? What alternative is there? How about not taking it? Works for most people.

    i'm not saying that at all. i think that the whole drug regulation system needs to be reformed, and all drug use needs to be monitored by doctors. this way the people with the inability to moderate their use to keep it in balance with their social responsibilities can be given the treatment required to bring about this more healthy way of approaching a given substance. what we are seeing in california and other places with medical marijuana is where all psychoactive drugs need to go. prescription only. sure there will be some who will bypass the regulatory systems but i doubt it would be any worse than your average country with alcohol and tobacco that isn't taxed so high it's almost banned. and sure, doctors will write scripts for people who shouldn't be taking a drug or taking as much of a drug, but this is something you can legislate and mitigate, and sure, there will be some people selling drugs without prescriptions, but several things will be at last set right:

    purity and contamination will be all but gone

    prices will drop and this in itself will reduce drug-related crime by reducing the amount of money required for the drugs

    overall rates of use will drop as the forbidden fruit thing is mostly eliminated, and the monitoring and control of rates of production goes into the hands of our elected officials who can then have some real control over how much drugs people have access to.

By this meaning alternating pulses through a tuned coil on both sides at a tuned frequency. The vibrational energy of a guitar string transmits quite efficiently to adjacent strings on a guitar, it stands to reason that, if like in the example of a low resistance wired coil vibrating at a frequency tuned to the length and width of the coil, the loss of energy in transmission would be much lower if the receiver coil was tuned to resonate at the same frequency or a close harmonic (1 or 2 octaves). The only thing that I am unsure of is this theoretical negation of resistance, which I understand is what the whole idea is based on.

    As far as safety goes, it would be quite safe. It is magnetism below a certain frequency and the only thing that might get damaged is inadvertently tuned circuits in electronics and possibly it may damage magnetic media that find themselves in the flux lines directly between receiver and transmitter. I believe the way to limit the distance that can be used is purely about current. Conversely the circuit is limited in capacity by this, putting too many loaded receiver circuits in its range will result in an overall diminution of power transfer to all of the devices.
