  1. Re:that really is a really bad development on First All-Drone USAF Air Wing · · Score: 1

    I didn't mean to imply that people in the military are bound to be conservative.

    What I mean is that because you require politicians to be part of a certain group of people you limit the voters choice. The "certain kinds" phrase wasn't meant to allude to anything.

    In this particular case you would force the politicians to go through an institution which is made up of people which didn't get there through a democratic process (a meritocratic one certainly, but that is not sufficient). If you aren't fit for the army you can't be a politician either even though you might otherwise qualify. You would give the armed forces way too much power over your lawmakers or over who becomes one.

    After all, I don't mind politicians mentioning their military service, you just can't make a law out of it.

    BTW, you will have to have a whole bunch of wars to properly train your politicians, I'm not sure this is what you wan't.

    >I really wished that there was a mandatory requirement for politicians to serve a tour of duty on the front line.

    Sounds like Heinlein but isn't a good idea. It allows only certain kinds of people to become the leader of a country. I think this is not democratic at all. I think one of the ideas behind a democratic society is that every citizen has a say in the political process and no one can take that right away. Allowing only certain kinds of politicians limits the options a voter has to vote for his representative.

    There are limits in place of course but even those are debated (see Mr. Schwarzenegger), so I doubt you would ever get lucky with your idea.

    In this case you would basically allow the military to run the country and have a monopoly on power. As much as Heinlein was a cheerleader for the US I think puting this idea to work would do your country a disservice.

    The political process doesn't exist for itself and shouldn't be abolished just because it would give you the leader you would like to see in power (John McCain?, he would probably object). It is a safeguard against people monopolizing power. As it is with all safety measures they are cumbersome but it is pointless to have them afterwards.

    You might be well aware of all this but sometimes the obvious needs to be spelt out.

It also inhibits acid attack on copper and brass. It does not contain arsenic, chlorinated hydrocarbons, or lead compounds. The addition of Rodine 213 inhibitor to hydrochloric acid solution provides maximum protection for equipment during: a. The removal of lime deposits or water scale from power plant boilers and piping systems and from evaporating equipment. b. The removal of scale and deposits from equipment in refineries, utility companies, paper mills, chemical plants and other industries. Rodine 213 meets the requirements of Military Specification Nos.

    Nukes won't prevent war.

    If you want to achieve a goal other than total annihilation of an opponent (glass parking lot) you leave open the possibility of a conventional war or limited nuclear war. Especially geographical closeness could enforce a conventional war.

    Notice that in the second world war Germany didn't use Chemical weapons because it didn't want to bring them into the game for fear of retaliation and reduced usefulness. The same thing might apply in future conflicts, you can't nuke the territory you want to occupy.

    Just face it, in the end even bad guys want to live.

    Also notice that we might find attacking states like North Korea or Iran unpleasant right now because our highly developed (I have no better words) societies have too much to loose from a couple of stray nukes or terror attacks.

    Thanks, you just made me have a look at Almasi and Gottlieb (1994) again, where else would I need it than on slashdot. Chapter 10 Section 3 and following is good to have a look at.

    Your last statement leaves me puzzled. It seems that you must have something to connect caches and memory with so we could be content with a simple bus which A&G describes as existing in Sequents cost effective machines.

    When you read further you come across the KSR1 which uses a hierarchical ring architecture, sporting large cashes which connect straight to disk through a second level cache. So there is no memory in our sense. Well I mean a ring is better than a bus, it gives the end nodes the same connectivity as all the other ones.

    Notice also that in Larrabie according to an Annandtech article, somebody mentioned here, the L2 is a per node L2. http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=3367&p=3

    The Networking chapter in A&G mentions other networks with much stronger connectedness than a ring but never mind CELL proves it right it seems also from their performance prediction shown on their wiki page.

    Anyway, I think that the difference between CELL and Larrabie is that Intel is pandering heavily to the slowest element in the computing environment - the programmer/user. Same old instruction set, simpler memory architecture (I'm not sure about your DMA only comment), lots of vague information about a product which is at least two years out while trying to keep up with the other guys, sounds like Intel. Funny enough they have 45nm now, and also with IA64 they tried to offer something with entertainment value to assembly programmers, so I can't even be angry.

    My assumption was that this rocket is either your only means to space and you have to assemble in orbit (I don't know how), or that for comparison you hitch a ride and pay by weight. Then having the Kg to orbit price helps comparing your options. However I doubt that you can get away with only paying for the weight, probably they let you pay for a part of the launch service and that won't be cheap.

    Also I just read somewhere (not just your comment) that hitching a ride is difficult and only infrequently an option.

    The reason this might not be entirely illegitimate a comparison is that the N-Prize doesn't require you to put the licensing and other non-technical stuff on the budget to win the prize, so in our wonderful world of engineering we only pay for the price to put a kilogram into orbit.

    Just as a side note regarding the non-technical aspect, if you plan to go into orbit you are most probably exceeding the amateur rocket class and you need a license from the FAA for an ELV:

    I don't know how much this costs but I fear you are going to lose as a hobbyist just because of the requirements. The guys from Cambridge may have a better chance to pull this off I guess.

    Also notice that the US is said to have the least complex regulations for you to reach space as a commercial enterprise for instance, so I wonder whether you will find an easier country to deal with.

    I agree with your third point but it holds some promise. Spaceflight has driven miniaturization and it will continue to do so unless some drastically cheaper way to orbit comes along. Also the N-Prize requirement says that your payload should not weigh more than 19.99g.

    If you go abroad to experience a different culture, and I think this is what you should do, then you should spent some effort in learning the language. Otherwise you will not enjoy it much unless your life mainly consists of work and the rest of it is just an annex. You will not be able to do much beside work because your engineering job or the like is the main place where people speak English thanks to the careful selection of HR. For anything outside work you will need to speak the local language because people without much exposure to English language, and just face it not all that many people get to go to university or abroad where they actually need it, can't really offer much in the way of a conversation otherwise.

    I have met some Americans around here and the better their language skills were the better they were integrated. Some actually have a life beyond just coming to work.

    You could just try to have a chat with some intern from abroad to get an idea how cumbersome a conversation can be when you have to think a while until you can form a sentence which conveys the meaning you want to get across, or when you just don't find the right idiom to express some thought which comes to you naturally
    in your native language, and finally when you pronounce the words you found in a way the other guy just can't understand them. You may be all nice and patient with the intern but it is just not the same.

    BTW, if you are going through anything like a culture shock lacking linguistic ability is just going to aggravate the situation. That means that you get out of the basement even less often than some jokesters around here already claim you do.

    Ultimately you have to get this language issue out of the way to immerse yourself into the other culture.

    Some American colleague told me that after his stay in Germany home wasn't quite the same anymore. Who knows, you could argue that a different culture gives you a whole different view on things. Maybe that what you had to put up with at home wasn't really necessary after all, or that what other peoples subject them selfs to is good not to have at home.
