Projects / sdd


sdd is a replacement for a program called 'dd'. sdd is much faster than dd in cases where input block size (ibs) is not equal to the output block size (obs). Statistics are more easily understood than those from 'dd'. Timing available, -time option will print transfer speed Timing & Statistics available at any time with SIGQUIT (^\) Can seek on input and output Fast null input Fast null output. Support for the RMT (Remote Tape Server) protocol makes remote I/O fast and easy.

        Before complaining you should _read_ what happens
        when compiling....

        The Schily Makfile system does use autoconf.

        However, it avoids to use autoconf to create self
        vodifying makefiles which is a technique of the
        1970s. The Schily Makefilesystem combines state
        of the art techniques:

        - Enhanced autoconf (the offocial is only 50% ready)

        - A structured set of object oriented
        make rules (this is an idea from the 1980s
        found in Plan9, the SunOS Kernel and the
        BSD Kernel, the Schily makefilesystem
        only added portability).

        - If you use 'smake' which is a automake
        enabled make program, the Schily
        Makefile system allows you to compile on
        more platforms then the FSF featured
        Method would allow! The platform specific
        make rules only add extra knowledge,
        they are not needed if you use a decent
        automake enabled make program because
        such a program will create the files
        when needed but unavailable.

        - It is not possible to use a POSIX only
        make for portable compilation.

        Instead of complaining, why not contribute back an
        improved version?

        I've had trouble figuring out how to use autoconf
        for my own projects, so it doesn't surprise me at
        all that not everyone has started using it.

        Build System
        Ick, ick ick. What the heck is wrong with standard
        autoconf? It's portable, it's familiar, and it's
        very versatile. There is no excuse for using such
        a crappy build system only to push your own make.
        Not to mention, you have files there for virtually
        every architecture known to man, and your
        quivering mound of hacks won't even work with
        POSIX make.
