Cocoa Search Engine
If you’re programming in Cocoa, Brian Cooke created a custom search engine for Cocoa using Rollyo that searches the main places you look for Cocoa answers. Its pretty handy.
Ruby on Rails is 1.0!
Congrats to the entire Ruby on Rails team!
Also - if you want to try out a Rails-powered site and you are a music fan, check out FanConcert: Music News by Fans for Fans, which is a social concert and album notification service. It’s created by my friend Ryan. He’s still working on it (i.e. it is in public beta, Google-style) but he’s constantly improving it.

How to fix certain SVN commit errors
If you’re getting an error message that looks like:
subversion/libsvn_client/commit.c:832: (apr_err=155005)
svn: Commit failed (details follow):
Then try backing up your project directory and re-check it out from Subversion using “svn co “.
If you then get something that looks like:
subversion/libsvn_wc/log.c:337: (apr_err=155009)
svn: In directory ‘YourProject/trunk/someDirectory’
subversion/libsvn_subr/io.c:565: (apr_err=2)
svn: Can’t copy ‘YourProject/trunk/someDirectory/.svn/tmp/text-base/foo.html.svn-base’ to ‘YourProject/trunk/someDirectory/foo.html.tmp’: No such file or directory
Then the problem may be that you have checked in both YourProject/trunk/someDirectory/foo.html and YourProject/trunk/someDirectory/Foo.html. Try to avoid this. This definitely causes problems on OS X and may on other systems.
To verify, execute “svn list /someDirectory/” and look for two versions of the file, but with different cases.
To fix, execute “svn remove /someDirectory/foo.html” or Foo.html, depending on which one you want to get rid of.
Poor Man’s FeedBurner
I wanted to get an idea of how many subscribers I had to my new blog MacHappy. It’s a blog I started to talk about Mac stuff and also the Mac apps I’m writing which I call Happy Apps.
I thought about using FeedBurner, but I really like hosting my own feeds. Plus I haven’t had the need for their wide array of services yet…except for the readership count.
So back to figuring out how many subscribers / readers for a blog. MacHappy is on Wordpress and its feed is at http://www.happyapps.com/blog/feed/, which means that the feeds all have “/blog/feed” in the URL. If you’re got a Wordpress blog, you’ll have the same sort of setup. This blog is hosted on Movable Type, which is a bit different since usually you have atom.xml or whatever you call your feed template (usually ending in .xml). I’ve actually got two feeds here: a feed for everything and a feed just for Eclipse.
Then you download your log file from your ISP.
Then run this nice series of piped commands (for Wordpress): grep /blog/feed yourLogFile | awk ‘{print $1}’ | sort | uniq | wc -l
(for Movable Type): grep .xml yourLogFile | awk ‘{print $1}’ | sort | uniq | wc -l
And for my eclipse.rss feed, something like grep .rss yourLogFile | awk ‘{print $1}’ | sort | uniq | wc -l
You should get a nice integer back, hopefully a nice big one. :)
It’s not exact since the same person could be checking from multiple locations throughout the day, but I think I’ll be using this to keep track of the trend.
