This page describes some of the things I have learnt about Apache from using it for four years.

Apache reports out of disk space when not

If Apache refuses to start with one of the following two errors in the error log:

 (28)No space left on device: Couldn't create accept lock

Summary : Sick server

This is a summary I (Mark) posted to the mailing list, concerning the problems I was having a while back and resolution, in case anyone sees a similar thing happen to them... Thanks for all your input :)

Compaq Proliant ML570, Smart Array controller 5300, RedHat 8.0.

What is DirectFB?

The graphics device on your computer is really just a big virtual drawing space in hardware with a defined set of calls to create picture changes. It has some functions to accelerate 2/3D drawing operations.

Generally these operations are implemented by the Xserver Driver which binds to the Abstracted VESAfb or actual device driver i.e. atidrv. However it is better to define an abstraction layer between the Xserver and the hardware driver; and this is what DirectFB does - in fact this is the same approach as DirectDraw2D in Windows.

What is it? Well it's like Linux + :-)

FreeBSD is a BSD based operating system that ran into legal problems similar to the ones that Linux is now finding itself in.

This slowed development down, letting a Certain Finn come up with a certain OS.

FreeBSD tends to be used on more servers than workstations and runs some of the internet's larger and more reliable web sites.

http://www.freebsd.org is the home page for it.

You might also like to try GhostBSD, based on FreeBSD, but as a live cd/dvd.

Anti-spam framework which incorporates textual analysis, RBLs, Bayesian statistics and on-line spam databases. Works very well indeed -- one big plus of SpamAssassin compared to the purely statistical filters is that it works pretty good straight out of the box, without requiring training.

Redhat's community based distribution, based on Redhat (obviously!). See http://fedora.redhat.com for more details.

Makes a nice and well put together desktop system using 2.6.5 kernel, Gnome 2.6 and Openoffice 1.1.

Cairo is a vector graphics library designed to provide high-quality display and print output.

Currently supported output targets include the X Window System, OpenGL (via glitz), in-memory image buffers, and image files (PNG and PostScript). Initial work has begin on support for PDF file output. Cairo is designed to produce identical output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension or OpenGL).

Cairo provides a stateful user-level API with capabilities similar to the PDF 1.4 imaging model.
