Ad 1: It's a precaution I take when I start learning a new system: install it on it's own hardware, or at least in a virtual machine. That way, I can tinker around as much as I want, and even have the system completely unusable, without endangering my main machine. (Some) VMs have the additional advantage of allowing snapshots, so you won't even have to reinstall.

Ad 2: Wikipedia:

Quote:

[...]Open sourced components are snapshots of the latest Solaris release under development. Sun has announced that future versions of its commercial Solaris operating system will be based on technology from the OpenSolaris project.[...]

Ad 3: As I said, commercial Unices are usually tied to some hardware and support contracts. Software-wise, they aren't made to be cutting-edge, but stable and tested.

Ad 4: You only listed 3 different OS: Linux, Solaris, and BSD Smilie

. For the Linux distributions you listed: they are pretty much the same. Fedora is the "staging ground" for Red Hat Enterprise Linux. CentOS is RHEL, without the commercial support, and some commercial extensions cut. Other distributions include SuSE (SuSE Linux Enterprise Server/OpenSuSE), Debian (Ubuntu), Slackware, and Gentoo.

Linux distributions usually have tools for most languages included, and a huge subset of that is available on other platforms (eg. the GNU Compiler Collection [C/C++/Objective-C/Java/FORTRAN/Ada], Perl, Python, Ruby, ...)

Does the assembler output differ between operating systems ?

The assembly code generated by assembler, from a C-source code depends on the CPU architecture underlying it, eg x-86 . Then does the assembler output of a simple C-source code (containing common function-calls of both windows and linux) differ between Operating Systems ?

NAME

       README.macos - Perl under Mac OS (Classic)

SYNOPSIS

       This document briefly describes perl under Mac OS (Classic).  If you are running perl under Mac OS X, you don't want to be here (unless you
       are in the Classic environment under Mac OS X).

       When we say "Mac OS" below, we mean Mac OS 7, 8, and 9, and not Mac OS X.

DESCRIPTION

       The latest perl source itself builds on Mac OS, with some additional pieces. Support for Mac OS is now in the perl core, and MacPerl is
       kept in close sync with regular perl releases.

       To build perl for Mac OS (as an MPW tool), you will need the addition of the macos subdirectory, distributed separately.  It includes extra
       source files, config files, and make files.  It also includes extra Mac-specific modules.

       To build the MacPerl application, you will also need the macperl directory, which includes the source files for creating the application
       itself.

       All of this is available from the development site, via HTTP (in the MacPerl Installer, which includes all the source and binaries) and
       anonymous CVS.

	       http://dev.macperl.org/

       The source is also in the main perl repository in the macperl branch (the 5.6 source is in the maint-5.6/macperl branch).

       You will also need compilers and libraries, all of them freely available.  These are linked to from the SourceForge site. Go that site for
       all things having to do with MacPerl development.

       MacPerl 5.6.1 and later are supported on Mac OS 8.1 and later, for 68040 and PowerPC architectures.  The MPW tool may be used on Mac OS
       7.5.5 and 68030 computers.

       MacPerl 5.2.0r4 is also available, on the CPAN and on SourceForge.  It is based on perl 5.004, and works with Mac OS 7.5.5 and 68030 com-
       puters.

AUTHOR

       perl was ported to Mac OS by Matthias Neeracher <neeracher@mac.com>.  It is currently maintained by Chris Nandor <pudge@pobox.com>.
