  1. Re:Bridge collapse prevention "someday" on The Science of Bridge Collapse Prevention · · Score: 2, Insightful

    We've been building bridges for the whole of recorded history, and some of them have stood for much of that time.
    and i'm sure many of them haven't

    sure if you build a stone arch accross a narrow vally in an area with no sismic problems then it will stay up for a very long time, especially if the area is too dry for much plant life. However it will be very expensive for the ammount of utility it gives.

    but of course we want more, we want our longest bridges longer, we want all our bridges able to stand being packed with heavy lorries we want to bridge accross fault lines and so on and of course like with everything we want it as cheaply as possible. The result is much narrower safety margins and use of new materials and construction styles which may suffer unanticipated problems. There is also the human nature to ignore problems until they become critical.

    sure shill bidding may be against policy but if you are carefull about it (e.g. don't use the same account for it too many times and don't bid insanely high) how would anyone know? Ebay has no way of knowing if buyer and seller ever completed the transaction or not unless one of them complains.

    Since nothing was copied illegally, and a valid serial number was purchased from Microsoft in exchange for actual money, you still feel it could be copyright infringement? I'm glad you don't make laws. Your speculation is ridiculous.
    Instead of using the software you purchased you made a copy of a different product, how is that not copyright infringement?

    Who's gonna know he's not using a legit copy of Windows?
    well there is wga, at the moment it seems they are being nice and just using failures to try and sell legit copies. However some must be wondering if and when MS will decide to go after someone who gets a wga failure and doesn't pay up. IIRC they are already giving rewards for snitching on the person who supplied the pirate software. The BSA has meant that corporate IT departments are paranoid about avoiding piracy and some of thier campaigns must rub off on the end users they deal with.

    afaict in countries like china pirate software is tolerated by the authorites to an extent it never would be in the west with pirate software being sold openly in many places (I have seen dodgy software for sale in the UK at computer markets but never in more general settings). Sure even for westerners there is friends and internet filesharing but the former requires you to have the right group of friends (especially now there is activation to be bypassed for retail copies and vlk holders are living in fear of thier keys being blacklisted by wga creating a huge ammount of work) and the latter anrequires you to have a lot of patiance with the dodgier parts of the internet and also brings the risk of trouble from your ISP.

  7. Re:Now the real question is.. on A Majority of Businesses Will Not Move To Vista · · Score: 1

    yes thats the paragraph I saw and the way I read that is that if you use retail or whitebox OEM media to do the downgrade you have to use an existing key then ring up and explain yourself to activate. Then I would assume that if you later need to reactivate the box you borrowed the key from you will probablly have to ring up and explain yourself again.

    as you say if you have access to a vlk and the media to go with it or you have access to big brand OEM media of the right brand then there is no problem but if not it sounds like you could end up spending quite a lot of time on the phone to MS.

    and If you don't already have appropriate media (say because all your existing media is big brand OEM media for the wrong brand) then it seems you have little choice but to buy a copy of XP retail (or bend the rules and buy a whitebox OEM pack).

  9. Re:The Linux alternate history game... on Old School Linux Remembered, Parts 0.02 & 0.03 · · Score: 1

    it's just not practical to keep stuffing more features into a monolithic kernel if you're not constantly getting more and more memory to run it on
    be carefull with your definition of monolithic.

    linux is monolithic in the sense that everything that is part of the kernel runs in the same address space and has access to everything else in the kernel. However it has a module system allowing kernel code to be loaded and unloaded (though unloading is unusual) at the request of users, applications or hardware detection systems.

    debian:/home/plugwash# ls -l /boot/vmlinuz-2.6.21-2-amd64
    -rw-r--r-- 1 root root 1570231 2007-07-10 23:18 /boot/vmlinuz-2.6.21-2-amd64
    debian:/home/plugwash# du -sh /lib/modules/
    67M /lib/modules/
    debian:/home/plugwash#

    as you can see from the above with a debian kernel (and I doubt debians kernels are much different from those of other major general purpose distros) the vast majority of kernel code is in the form of modules. From a ram usage perspective I don't see how this is much different from a microkernel based architecture.

    that PDF doesn't say anything about them providing a new key, it appears they have to use thier existing XP key and then call the activation line and tell them they are downgrading. Presumablly this means whenever either box needs reactivation in future more phone calls will be required.

    all in all it seems fairly painfull for those who want to downgrade and don't have access to XP vlk media.

    America already has those - why would anyone need another engineer?
    because there are big problems to be sorted out over the next few decades (that is over the working life of people who are graduating now).

    where are we going to get our energy from? conventional oil is on its way out, coal and unconventional oil are heavilly pollouting. Natual gas is not as critical as oil but has some similar problems. Add to that the fact that the developing world is demanding ever more energy and people in much of the west are scared shitless of nuclear and things do not look good.

    related to the above how are we going to deal with global warming? are we going to try and stop it (all attempts to do this so far have been pretty futile) or are we going to have to deal with the problems it brings? either way engineers will be needed!

    how are we going to power the cars, planes and trains (yes i know trains can be electric but afaict the maintinance costs make that only feasible on heavilly used lines and there is also the problem of trains that must run between areas using incompatible systems) that are so vital to our modern economy when all our energy comes from sources that are unsuitable for portable use? the hydrogen economy is one possible soloution but it won't be an easy one.

    Where are people in areas where the deep aquifers are being pumped dry going to get thier water from when those run out?

    and we need all the engineers who work to design variants on a theme. Sure two big buildings are similar but each one will need a lot of new design work either because people want it to look different or because of different local conditions.

    and of course besides all that there is also inventing the next big things which is something the west must keep doing if we want to keep on top of the economic pile.
