Here’s a couple articles that I’m going to study of the next week or so: Understanding XP through FDD: [An] attempt to understand Extreme Programming (XP) better by studying Feature-Driven Development (FDD). When reading about FDD, you sometimes get the feeling that it is very close to XP. For example, features in FDD and user stories in XP have much in common. But as you read more, you realize that the two approaches are fundamentally different, that they are based on different assumptions.
Here is the corresponding discussion about Understanding XP through FDD on www.featuredrivendevelopment.com

It’s always useful to consult or use someone else’s checklists to augment or as a starting point for your own checklists. Cardboard Nu has a good selection of checklists comprising of Weekly, Planning, Start Of Project, End Of Project, Development Environment and New Team Member Project Management Checklists.

MailTunnel Description
The author writes:
Mailtunnel creates a bidirectional virtual data path tunnelled in E-Mail
messages. This can be useful for users behind restrictive firewalls that
only allow Mail-Access (usually through a central mailhub).
In a situation like the above, it’s possible to use mailtunnel to tunnel
anything from simple telnet sessions to SSH-PPP VPNs (practically anything
that can be tunneled over TCP/IP) to a non-blocked system on the internet.
This allows users(well..) behind even the nastiest firewalls to access
resources they’re not ment to access.
I wrote this piece of software in the spirit that it should be possible to
gain full netaccess, no matter how good you’re firewalled.
