  1. Re:Nah. The really deadly stuff on City Officials Almost Ban Foam Cups · · Score: 1

    H_2SO_4 is Sulphuric acid not Hydrosulphuric acid, nor Hydrosulphate acid nor Hydrosulphuric oxide acid.

    It probably has to do with the fact that H_2O + SO_2 => Sulphuric acid; and H_2 + Cl_2 => Hydrochloric acid.

    There are several JVM-in-(micro/nano)kernel with purely Java drivers and in some cases, purely Java services usually implemented in-kernel.

    http://jos.sourceforge.net/ is one of them. There was another one that I looked at before, but I don't remember its name or address.

    OS X isn't a rewrite of OS 9. It is a whole new system. OS 9 may have been partially rewritten for use with the OS X Classic environment.

    In any case, OS X was not a complete rewrite either. It was based heavily on OPENSTEP and NeXTSTEP before that.

    "Sorry, this program has unexpectedly quit because of a programming error"

    Maps to, among other things:

    SIGSEGV "Segmentation fault"
    ENOMEM "Out of memory"
    ENOSYS "No such system call"

    As far as I am concerned, working programs are more important to the user than knowledge that the program has failed, and to have more working programs, the error messages have to be more informative.

    Though, it would be more convenient to have a Mozilla TrackBack or GNOME Bug Buddy type program to collect this debugging information...

    # ./buggy-program
    SIGSEGV (Segmentation fault) recieved.
    The program has been terminated.

  9. Re:Microsoft demonized the command prompt... on The Command Line - Best Newbie Interface? · · Score: 1

    Windows Server 2003 (or Longhorn) purportedly has a command-line and shell-scripting system that comes close to the power of bash.

    Mostly because the admins demand batch jobs that can do more. (And, being a batch job, means that none of the programs should require interactive use... Unfortunately, even most system programs require interactive use)

    The GPL does not require this crediting -- therefore, any licence that does is not compatible.

    Most of C's quirks are derived from assembly.

    Assembly is a do-it-yourself kind of language. Bounds checking is strictly optional.

  25. Re:Isn't this already possible with segmentation? on AMD Could Profit from Buffer-Overflow Protection · · Score: 1

    Virtually all current 32-bit protected mode i386 OS kernels do not use segmentation.

    There are a number of reasons, including the monstrosity known as a far pointer. Pointers that don't fit in one register, nor load into one.

    When you are returned a far pointer, you cannot just use it... You must first load a segment selector register, and there are only 4 for use with data: DS, ES, FS, GS. Then, you can indirect through a far pointer.
