Ran across an interesting talk about memcached here: http://www.facebook.com/note.php?note_id=393913...

This gets a bit in-depth, but it is a description of how Facebook is making use of, and modifying, memcached and the considerations in scaling Web 2.0 applications. There seem to be a lot of people out there using ROR to build applications for Facebook.

Wow. That must be some of that fancy Rails magic I keep hearing about.

"If you are adapting Assignment 5 for the final project, you may only use one self-defined feature."

I'm guessing that's from last year?

John:

At one point, you used a button in your GUI file window that brought up Terminal already cd'd to that particular directory. What was that? My wrists hurt.

Good enough(I just reread that and it sounded kind-of not nice when it was intended just as conversational...sorry).

I just used './', but that's just Unix-specific, right?

Reading for Sept 24. Going through the code in the Ruby text...p 78 in the pdf version. The code calls on the method 'require_relative', which is not part of the base until 1.9(I'm running 1.86). I get an 'undefined method' error. My guess is that just using 'require' and the full path to the file will make it work.

It's Dave, actually.
I may be off the map for what the book says. I haven't bought it yet, and I don't want to mislead anyone. But I think a pretty solid overall point to make is that Gems gets updated first.

Step 1 is actually making sure that XCode is installed on your system. That sets you up with Rails 1.2.6 and Gems 1.0.

I didn't realize that Gems had a flag for self-updating. What I did was per the ruby on rails download page.. Instead of updating Rails first, I went to the link for downloading Gems

Then I used Gems to update Rails. In Terminal type "gem update rails". Gems is pretty key because its the package manager.

For those who are doing this in OSX 10.5, make sure you update Gems before you use it to update Rails. If you don't use the updated version of Gems to execute 'gem update rails', it doesn't seem to know which version it has and you will end up with two versions of rails and some broken links in whatever system variables Rails is using to know which version it is. The rails website leads you to believe that you should run 'gem update rails' as the first step then run the setup.rb script to update gems.

If you do go down this path, run 'gem uninstall rails' and pick the latest version. Then use the newly installed Gems to re-run 'gem update rails'. After that, everything should work OK.

At least, that has been my experience.
