  1. Re:MS tax on Lenovo Delivers SuSE Linux-Based ThinkPads · · Score: 1

    There are a couple of issues with easy installation, none of them insurmountable but most of them tricky.

    the first is partitioning, you could of course make an installer that just wiped everything out and enforced it's preffered structure by default but many many people would complain if you did.

    the second and more significant one is the huge huge range of PC hardware out there. This makes it practically impossible for an OS vendor to test on every possible configuration of hardware and the OS vendor can only ship drivers for hardware they know about and have either written drivers for themselves or got suitable licenses in place to allow them to redistribute the manufacturers driver.

    Just be very careful when Greenspunning more sophisticated capabilities you end up needing
    Maybe so but equally overusing library functions especially in embedded environments can bring in overhead you can't afford. That may be time overhead but it may also be code size overhead or ram overhead.

    while COM-style AddRef/Release reference counting breaks realtime since Release can cascade indefinitely.
    True but if you are making and dumping objects willy nilly then no system is going to make you safe from running out of time. For stuff that has to be that predictable it is often a good idea to just completely avoid dynamic memory or at least keep a very close eye on when and at what priority objects are being constructed and disposed of.

    In either case, the PC is not exactly the best one to run Engineering/Math or even a compiler on.
    I can't say I agree, there are some small subcategories of both software development (mainly packaging/testing work that requires frequent recompilation of huge source trees from scratch), engineering (FPGA development, finite element work) and math (doing big numerical approximations) for which huge ammounts of computing power are required but I belive such applications are the exception not the rule.

    But watermarking? Eh. I don't care. You're supposed to not be sharing music you bought, and unless someone actually breaks in and steals it, there's really no legitimate reason to find music that you bought out on the net somewhere.
    For many years even if technically illegal it was quite normal to share music with friends.

    Also PC repair places are well known for taking copies of media (yes, this is definately wrong but very very common).

    And hacking is another possibility it doesn't have to be a physical breakin.

    What worries me is if a copy sold to joe blogs ends up on a major torrent site joe blogs will be blamed for all those copies even though all he really did was send his PC in for repair or give one track to a friend or got hacked.

    AMD did produce a 486 clone and it lasted for many years it just took them a bit longer because IIRC they had to reverse engineer it.

    The only reason there was competition in the PC processor market in the first place was because IBM insisted on it. As IBM lost power there was noone with the clout to pressure intel into releasing it's designs so the other manufacturers of PC processors had to switch to reverse engineering or making thier own designs.

    Your job is not to know the languages and the tools
    I think to be a decent engineer you should know at least one tool/language in each relavent category. It may or may not be the same one you end up using but at least you will know the basic concepts. To use an analogy from the world of electronics in PCB design the tools will change as will the number of layers (though i'm sure there are still a hell of a lot of 1 and 2 layer boards being designed and made) but the concepts of PCB design (tracks, vias, pads, pours etc) don't.

    Since C and C++ practically define thier own categories and are very common that means that IMO you should learn them both though not nessacerally in great detail. C fills the niche of being about as close to the metal as you can get without actually writing assembler. C++ fills the niche of where you still want tight control but some OOP capabilities would be usefull. For higher level stuff things aren't so settled but still I think knowing at least one GUI framework and at least one high level networking library and so on will be very usefull to you later when you come accross a similar thing in future.

    I have to say I think using the 4 pin connector for the computer end (which is pracitally ubiguous on laptops though as you say far less common on desktops) was a bad thing for firewire. It means that either device manufacturers have to ship two cables one of which can't be used or consumers have to buy the cable seperately.

    Also, the software/firmware overhead will continue to get more complex. The design goal, I think, is to make it so that only Large Companies can design any hardware peripherals.
    If you don't need high performance then you can do USB full speed with a single not too expensive microcontroller that is availible in a DIP package and for which the firmware is freely downloadable from the manufacturers website. Hell you can even get free samples of this chip.

    If you need high speed then things do get harder simply because dealing with 480 megabits per second is not trivial but it certainly isn't large companies only either.

    No it is not like a null modem cable. Afaict USB is always wired D+ to D+ and D- to D-.

    There are two types of full size USB plugs, A and B. A always goes at the host end B always goes at the perhipheral end.

    There are also two types of mini plugs mini A and mini B. But unlike with the full size connectors there is also a socket called mini AB that takes both. The same applies to the micro connectors.

    Mini plugs have five pins. The extra pin is used to indicate to a device with a mini AB socket whether it should be acting as a host or as a perhiperal. (I think in a mini B plug it is open circuit in a mini A plug it is connected to ground but i'm not positive and the information seems to have dissapeared from wikipedia).

    If everyone followed the rules it would be easy as you would not be able to create an out of whack network. Sadly a wide variety of noncompliant cables and adaptors are commonly availible, the difference between mini-A and mini-B is not that obvious to the untrained eye and many people are unaware that mini-A even exists.

    The main issue with ethernet is what you run on top. TCP/IP is a very nice protocol but requires all devices to be using a matching setup, you can use your own protocol of course but that isn't free of issues either. Having perhiperal devices on the network you also use for connectivity between your PCs also raises some major security considerations. Yes you could have two seperate ethernet networks but then you have to make sure people plug thier devices into the right one.

    Also the normal variants of ethernet are rather power hungry because they are designed to support long runs and by using a specialist variant you just lost most of the advantages of using ethernet.

    the gold standard fixes the exchange rate between gold and the currency. So a fixed ammount of gold will get you a fixed ammount of currency and vice-versa. The value of gold and the currency tied to it will of course vary relative to other commodities.

    If we assume governments don't cheat on the gold standard (that is they hold enough gold to back up all the money they issue, something not all did in practice) then what this means is that if gold becomes rarer (say because it is used in some valuable new industrial process) you get deflation. If on the other hand gold becomes more plentiful (say the discovery of a big new gold deposit) you get inflation.

    Which would you rather have controlling the value of your currency? Your government (which is presumablly acting at least somewhat in the direction of self preservation) or the variations of a metal market?

    A gold standard also wastes a lot of rescourses mining a difficult to mine commodity just to store it in bank vaults.
