operating system

Mac OS X

A Webel zone dedicated to Mac OS X, by someone who until last year loved and loathed Linux and KDE (which I still think has many superior window manager and file manager features).


For many years Linux (RedHat then OpenSuse) was the primary operating system for my Webel consultancy, and Linux was crucial to my work with many scientific institutes and software engineering clients. Thankyou Linus et al !

Although I now work mostly under Mac OS X, I often still use Linux.

Mac OS X

I am simply in love with the fact that Apple (eventually) chose a UNIX-based operating system and I currently work mostly under Mac OS X, sometimes still under Linux, and very, very rarely under Windows. I often still need to use a UNIX shell under Mac OS X for my work.

I used to be an oft-frustrated Linux "die hard"; I was able to migrate most of my work from Linux to Mac OS X in about 2-3 days and got working almost immediately ! I honestly do not miss Linux much, although I do still miss a couple of K Desktop Enviroment (KDE) applications, like the multiple split panes and internet-fluency of Konqueror, and I miss Weex web mirroring. (BTW I did not manage to get many of the DarwinPorts for Mac OS X Leopard to work and gave up.)

It is not, however, true that everything "just works" under Mac OS X, it is blatantly false advertising. There are in fact a lot of bugs, the worst being the infamous "no wake from pseudo sleep" problem that afflicts the Mac Book Pro, and which has cost me many days of lost work and time, with no solutions from a Mac "genius" or from Apple.

It is true that I have far fewer problems under Mac OS X than I had under Linux (especially with apps) and of course fewer than under Windows. So Apple ads should only say that Macs have far fewer problems than many other machines, and Apple should stop telling fibs.

Anyway, I forgive Apple; I love my MacBook Pro.

When I was a young teenager I used an Apple II then an Apple IIe at high school and that is how I first learnt to program computers.

IBM Multiple Virtual Storage (MVS)

I used it for "supercomputer" numerical simulations of supernovae in 1989-1990 at Institute for Theoretical Astrophysics, University of Heidelberg, Germany. I even survived the infamous Job Control Language (JCL) and Time Sharing Option (TSO) "user interfaces".

I used VAX/VMS as a physics student in 1988 at Department of Astrophysics, School of Physics, University of Sydney and even did some FORTRAN computer simulations and wrote my honours thesis on one: An analysis of image formation by MOST (Molonglo Observatory Synthesis radioTelescope)

Microsoft Windows

I have - for better or worse - used most versions of Windows frequently in both professionally and for personal use.


My child sometimes1 plays computer games on Win XP; sometimes it crashes or the "compatible" games don't install or run properly and he gets very upset.

  • 1. Since Xmas 2008 he plays computer games on the Nintendo Wii; it never crashes, and he only gets upset when he loses.

I confess that I simply can't stand being inside an MS-DOS command-line interface, and why should I when I can be inside a UNIX shell (under Mac OS X or Linux, for example) ? This technology is clearly marked "historical".


I have used UNIX for well over 20 years (showing my age there), including variants such as: Linux, Mac OS X, Sun Solaris, SGI IRIX, HP-UX, IBM AIX, BSD and the UNIX-like Domain-OS, (given in no particular order of preference).
