Subversion server requirements
Information compiled from different internet sources….
Subversion server has been certified on:
Windows 2003/2008 Server 32/64 bit:
– JRE 1.6 or JDK 1.6
Note for windows: Subversion Edge works on all versions of Windows XP and later, including Windows Vista and Windows 7.
Red Hat Enterprise Linux 5.x, CentOS 5.x, SuSE Linux Enterprise 11.x 32/64 bit:
– Java 1.6 JRE/JDK must be installed. We recommend the JRE provided by Sun/Oracle. Python 2.4 to 2.6 must be installed.
CollabNet Subversion Server v1.6.13 (for Sun Solaris 10 / SPARC):
Supported Subversion backend: FSFS
Supported Apache Modules: mod_dav_svn, mod_authz_svn, SSL, LDAP
Prerequisites:
– Install the CollabNet Subversion Client before the CollabNet Subversion Server.
– The user needs superuser (root) privileges to install and uninstall CollabNet Subversion.
– If you want ViewVC support, install the “extras” package after the server, but before the server configuration is performed.
CollabNet Subversion Server 1.6 (Platform: Solaris 10 / x86):
Supported Subversion backend: FSFS
Supported Apache Modules: mod_dav_svn, mod_authz_svn, SSL, LDAP
Prerequisites:
– Install the CollabNet Subversion Client before the CollabNet Subversion Server.
– The user needs superuser (root) privileges to install and uninstall CollabNet Subversion.
– If you want ViewVC support, install the “extras” package after the server, but before the server configuration is performed.
Subversion server also runs on:
Explicitely listed OSes with available binaries: AIX, Debian Linux, Fedora, FreeBSD, HP-UX, NetBSD, OpenBSD, Mac OS X, Suse, Ubuntu.
Subversion can also be compiled from source. Subversion should work on any operating system that the Apache httpd server runs on: Windows, Linux, all flavors of BSD, Mac OS X, Netware, and others.
Professional subversion support from third-parties:
All major platforms, available from multiple companies worldwide.

Alternatives to ESX(i) on Mac OS X
VMWare ESX(i) does not support Mac OS X. The hardware does not match, and the license is in conflict.
VMWare has a solution for Mac OS X that is compatible with ESX VMs under the name of Fusion. However, this is a client application and the headless mode has been disabled in its latest release. It means one has to start a client-session and in there start the server…. As such, for running a server, VMWare has no viable solution.
Leaves us with investigating other alternatives.
- Installing ESX on a Mac PRO.
- Installing VirtualBOX headless.
- Installing Parallels headless.
For running Virtual BOX headless, we will need to set Virtual BOX in the launchd (yes, Mac OS X has no init.d), and figure out how to get it working on different versions. 10.4, 10.5, 10.6 seem to be slightly different.
Secondly, we will need to get RDP connections to these VMs.
Thirdle, we will need to convert back and forward machines from ESX and/or Parallels into Virtual BOX.

Internet explorer officially dead
On web-sites for IT professionals, we see the Microsoft market share declining since a couple of years. Depending on target audience, we see Firefox taking somewhere in between 50% to 80%. However, statistics are statistics, and huge differences can be seen based on who is metering. In Germany/Finland, the public as a whole use open source browsers. In the Netherlands, UK, US, a lot of African countries, … you see a larger portion of the population using Internet Explorer. Everyone uses his/her own statistics to prove a point. Now, everyone seems convinced the trend is final and the world has gone one leap forward in being open and free.

Remark: Micrsoft did not acknowledge, they are still buzzing around new versions and contesting figures at the same time. At least the press is convinced and most professionals know.
