Mutt has a little-known feature to detect duplicate messages. I’m quite sure it detects duplicates by their Message-ID header, but it could be from something else in addition to that. You can do a pattern match duplicate messages in a mailbox and do whatever with them, e.g. delete or move them somewhere else.

Let say you want to delete all duplicate messages in the current mailbox. Just do a tag-pattern (bound to T here), put in ~= as the pattern, then all duplicates will be tagged. After that, you can delete tagged messages (bound to ;d, or just d if you have $auto_tag=yes).

Duplicate messages are also indicated by = in the thread if you sort the messages by thread and you have $duplicates_thread=yes (it’s yes by default).

1. I finally read this article (which had been sitting for a long time in my thick pile of printed “read-later” articles) from Apple Developer Connection about XMLHttpRequest which plays a major part in AJAX, which has been discussed a lot lately in the web development area and is used by popular services such as Gmail, Google Maps, Google Suggest and many more.

2. Maybe I should have named this category “Things I Learned Yesterday” since I usually post after midnight.

3. There are still a lot of people who are so naive and believe everything they got from the Internet or from forwarded emails, especially urban-legend or scarelore kind of stories. I hate those.

4. CeBIT Australia exists and it will be held from 24 to 26 May 2005 at Sydney Exhibition Centre in Darling Harbour. I’ll be there if I don’t have any exams or anything like that during that time. Free online registration.

5. Need to put less ginger and more salted fish for my spicy eggplant with minced pork.

6. A second look on iSCSI and iSCSI on Linux, and a first introduction to Vinum Volume Manager after reading a Slashdot post about Firewire storage.

7. There are several available options for backup solutions that are POSIX ACL aware, including using star, proper backup program like Arkeia, patched NFS (out-of-the-box with SuSE), rsync with ACL patch, etc. Info from this post, googled after answering a mailing list post.

8. “IT Research Methods” is such a boring and useless (at least for me) subject. It’s hard to force myself to do the assignments for this subject. I wouldn’t have taken the subject if it weren’t mandatory. Oh, what the hell, might as well make something useful out of it since I’ve already paid for it.

9. Evolution 2.0.x doesn’t provide an alarm for contact items such as for contact birthdays and anniversaries. I haven’t looked at the source code yet so I don’t know how hard it is to implement this. It’s surprising since I thought many people would have wanted this useful feature.

Runlevels in Gentoo are meaningful names instead of numbers. However, underneath they are still numbers, and the mapping is done in /etc/inittab. The symlinks are in /etc/runlevels.

    l0:0:wait:/sbin/rc shutdown
    l1:S1:wait:/sbin/rc single
    l2:2:wait:/sbin/rc nonetwork
    l3:3:wait:/sbin/rc default
    l4:4:wait:/sbin/rc default
    l5:5:wait:/sbin/rc default
    l6:6:wait:/sbin/rc reboot

This is different than what I was used to (Red Hat and Fedora). In RH or Fedora, runlevel 3 is the default runlevel with no X, and runlevel 5 will start X and a graphical login manager like gdm. In Gentoo by default the graphical login manager is started at boot when the xdm service is added to the default runlevel with rc-update add xdm default.

As you see from the snippet of my /etc/inittab above, runlevels 3, 4 and 5 all map to the default runlevel. So if I wanted to make runlevel 3 and 5 behave like RH or Fedora, I could change the map for runlevel 3 to, say, console and then create the console directory in /etc/runlevels then start adding the services I want to start in the console runlevel with rc-update add ... console, minus xdm of course.

6. There’s a Japanese pr0n model/actor named Anna Ohura, not to be confused with Anne Ahira. (Via a dream I had the other night. As if I’d tell you.)

8. The notorious TBE managed to screw up my Firefox, again, after an upgrade. I had to make a backup of my Firefox profile, delete the extensions directory and reinstall all of my Firefox extensions. It was strange that after I reinstall TBE it was working fine again. So I stuck with it, for now… but one of these days…

9. I finally know what Podcasting is about. I’ve heard about it for so long but I couldn’t be bothered to look it up in Wikipedia or Google until this morning. (Via blogwalking to Priyadi)

10. There’s a Wiki clone written in Ruby called Instiki that seems to be recommended by some people. Not in portage yet, so I haven’t bothered trying. (Via Nat)

I was looking for a way for CVS to send email whenever someone commits something in the repository. It’s possible by editing the CVSROOT/loginfo file and specifying a handler script. The script can basically do whatever with the information, including sending emails.

I came across a post talking about utilising the CVS loginfo file, but with a twist. It outputs to RSS instead of emails. Clever.

I modified the script to work with our work environment. Nothing major. But it got me learning Ruby. This was my first “fling” with Ruby. And I love it.
