Sony made this commercial in SF using 250,000 superballs and they used no CG at all! That's right they really did this:

Why I am pissed at Courier-IMAP

So for a few years I have been running a combination of Qmail, Courier-IMAP and Vmailmgr to allow for multiple virtual domains with many users without having to add each user to the system. I was doing some upgrading last night and I found out that the fine folks over at Courier have changed they way their authdaemon system works so that it is now incompatible with vmailmgr. Here is what they have to say about it:

I can only see the following minuses from losing the non-daemonized configuration. I believe the minuses are greatly outranked by the pluses.

There are some third party configuration libraries that only work in a non-daemonized configuration. I'm aware of one such library, vmailmgr. Unless it's been updated to work in daemonized mode, it will no longer work.

Great! So I just had to downgrade my upgrade of courier-imap. I am going to change my whole system soon and stop using vmailmgr and possible even qmail too. We'll see what happens.

Fixed Gear Gallery and Questions

So I sent photos of my fixie to fixed gear gallery and they posted them up along with my write up. When I woke up this morning I had a couple of emails asking me questions:

i have the same frame, but dont know how to get the shift lever mounts off. any help? also, what ratio?

Ok let me see if I can remember how I did this.

  1. unscrew the levers.
  2. I think I pried up the little plastic ring with my finger nail and then just turned it. One side is fixed and one side is like a nut.
  3. After you remove one side the other will just come out after you jiggle it a little.

Ratio:

  • Chainring: 42 teeth
  • Cog: 14 teeth
  • 78.8 gear inches

I saw you bike at fixedgeargallery.com (very nice by the way) and read that you had used a half link. I am currently building on a old reynold's 531 road frame with horizontal drop-outs so that shouldn't cause any problems but I have been thinking aboout converting my old kona kilauea mountainbike to my everyday fixie. The kona has more or less vertical dropouts so I have been told that the only way to go is the white industries ENO hub but I don't feel that I want to spend that much money on a hub so maybe the half link solution could be the thing for me. How do you construct a half link and if you would have time some day could you send me a picture of what it looks like? Any help would much appreciated.

The thing about the half link is that it may or may not work. You really have to try to know, you might not even need a half link depending on your bike's geometry. The half link just allows you to shorten the chain by half a link. It looks like a short link in a chain, but instead of a pin it has a screw and a flat square nut. It cost me $10 from the bicycle kitchen, I'm sure you could find one online. Sheldon Brown has a shot of a half link here on is great website.
