Eclipse Online Collaboration
Problem:
Multiple sites with multiple developers all over the world. Some sites in different timezones. Developers across these sites may need to collaborate, to look at code at the same time. To discuss/review and develop it.
Need:
A collaborative framework in which to perform this. Simple Instant Messaging not enough. IMs become cumbersome when trying to discuss complex this such as code. The collaboration framework would include some form of instant messaging.
Solution:
Eclipse Communication Framework.
http://www.eclipse.org/ecf/documentation.php
Implementation on this that looks very promising, even for inter-office collaboration.
http://live.eclipse.org/node/543
Need to Know:
Code base, in Cola for instance, do the collaborators both have a copy of the modified code ? Or is it a host/client arrangement.
Security, what ports etc?
?

Mylyn and Xplanner
The webinar here gives an excellent overview of Mylyn, which is a task based UI for eclipse. I'm very interested to see how it would work with something like XPlanner.

File System Visualization
Link to linux.com on the subject.
Also check out this.
Getting xcruise going on Kubuntu was pretty easy, just install dev packages for X11 and XAW. The code itself is ok, and seems to run well. The limitation for me was it was hard to tell the size of directories they don't always face the right way. The navigation was also a little diffcult in that tyou get disorientated easily. This was a point the author also made.
As far as file system visualization goes I also looked at.
Filelight , on kubuntu 6.10 it is installable with apt-get or adept. I quite like it make it really easy to find out where the big files are and it scans the file system quite quickly. Defintely a thumbs up.
GDMap, works on kubuntu installable out of the box on 6.10. Its a lot like SpaceMonger, the display is good. You can't navigate with it. I'd still prefer Filelight.
I have noticed a limitiation in both Filelight and GDMap. They both cannot handle very large directories, I have one that is 13Gb and neither application attempts to display it. I'd guess and say the counter used to count size of files and directories isn't large enough.

Eclipse - XP Quote Key.
The quote key (") began change its behavior while using eclipse. What would
happen when pressing " is that it wouldn't appear until another key was
typed. Some of the other keys typed would cause french characters to
appear.
This was caused because XP was switching the keyboard layout after a
Shift-Left Alt combination was hit. I used this key combination in
eclipse and hence it triggered the behavior.
To change this: Start -> Control Panel -> Regional and Language Options
[Advanved] (Details) (Key Settings)
Select /Switch between input languages/ Click (Change Key Sequence)
De select /Switch input languages/ and / Switch keyboard layouts/
Click (Ok) all the way out.
Obvious really.

magic-smtpd and TLS
To get magic-smptd working with TLS.
From my qmailrocks.org installation of qmail. I made a symlink from /var/qmail/bin/magic-smptd to /var/qmail/bin/qmail/qmail-smptd
I then configured a bunch of files in /etc/magic-mail/control the ones applicable to TLS can be seen here, out put provided by magic-smptd -s
The problem I found with the .pem file created in the qmailrocks.org instructions was that it doesn't contain the DH part. So I found if I followed the relevent instructions for magic-smtpd and cat'ed the DH to my .pem things worked.
The other tip is to make sure the CN (Common Name) is the fqdn of your mail server.
