Exploring Leopard with DTrace
Dtrace is very cool, glad it is coming to Mac OS X.
"A few years back, Sun Microsystems developed DTrace: a new and innovative way to trace running software on live systems. DTrace enables developers and administrators to "see" what their code, and others' code, is doing in a flexible and dynamic way. With the release of Leopard, Apple has brought DTrace to Mac OS X."

Lazy Programming
Lazy programming is a general concept of delaying the processing of a function or request until the results are needed. Thinking in terms of lazy programming can help you rid your code of unneeded computation and restructure programs to be more problem-oriented.

Securing your VNC connection using SSH
VNC stands for Virtual Network Computing. It is remote control software which allows you to view and fully interact with one computer desktop using a VNC viewer on another computer desktop anywhere on the LAN or Internet. The two computers don't even have to be the same type, so for example you can use VNC to view a Windows XP desktop at the office on a Linux or Mac computer at home.
Once you are connected, traffic between the viewer and the server is unencrypted, and could be sniffed by someone with access to the intervening network. Is security imported to you, we recommend tunneling the VNC protocol through some more secure channel such as SSH. This workshop describes how to connect from a Windows XP client to a Linux (OpenSuse 10.3) server via VNC and to tunnel this connection using SSH.

Working with vast raster images: NIP2
nip2 is a graphical front end to the VIPS package.VIPS is an image processing system designed with efficiency in mind. It is good with large images (images larger than the amount of RAM in your machine),and for working with colour. It can perform many image manipulation tasks much faster than other packages such as ImageMagick and the GIMP and includes some special features such as seating single "mosaic" images from multiple parts.

Virtual Users And Domains With Postfix & Courier
This document describes how to install a Postfix mail server that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I will also demonstrate the installation and configuration of Courier (Courier-POP3, Courier-IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I will show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses.

We're only Human after all: a review of Ubuntu 7.1
Nice review of Ubuntu 7.10.
"I tested the Ubuntu 7.10 installer on several computers and didn't encounter any noteworthy problems. On my desktop computer, which uses three monitors and two graphics cards, I had to unplug two of the three monitors in order to get the LiveCD environment to display properly. Aside from that, I have been able to install Ubuntu 7.10 on all of my systems without the need for additional workarounds."

Accessing DFS and NFS V4 Simultaneously
This article provides guidance to DCE or DFS users who are migrating from DCE or DFS to Kerberos/NFS V4. During the transition period, these users need to be authenticated and authorized to use both DFS and NFS V4 directories. This article answers some basic questions, such as, "Can the DCE authentication server be used as a Kerberos server for NFS V4 with a Kerberos client?"
