Since I tend to forget ::

svn propedit svn:ignore directory

then *.log, etc.. that you would expect in a .cvsignore.

If your working on RedHat enterprise 4, trying to install rmagick and you get an error like this ::

Magick::ImageMagickError (unable to read font `/usr/share/fonts/default/Type1/n019003l.pfb'):

try installing urw-fonts. That is all.

I’m not much for re-canning Techcrunch posts, but edocr seems pretty neat. Check out this Vi cheat sheet.

I should have really taken better notes as I got setup using fink, but here’s a braindump of what I needed for rails to work for me. Note, rmagick and me are not near as angry with each other as we were under macports.

Install Fink

Go Here - You should be able to figure out the install.

Set it to unstable

# Edit /sw/etc/fink.conf
# set Trees line
Trees: local/main stable/main stable/crypto unstable/main unstable/crypto

Edit Jan 21, 2008: You’ll probably want to do a fink update-all and/or fink -dv selfupdate here.

Install fink packages

$> sudo fink install mysql mysql-client  mysql15-dev mysql15-shlibs
....
$> sudo fink install ruby ruby18 ruby18-dev ruby18-shlibs rubygems-rb18
....

Edit Jan 21, 2008: If you want rmagick, you’ll need to fink install imagemagick or imagemagick-nox .. it will take a while

Make sure you’re using the fink ruby

You may need to open a new shell or update your $PATH but this what it’ll look like if it’s correct

jro@fireant:~/Desktop$ which ruby
/sw/bin/ruby

Time for some gems

$> sudo gem update --system
....
$> sudo gem update
....
$> sudo gem install mysql
....
$> sudo gem install -y rails
....
$> sudo gem install rmagick -- --disable-htmldoc
....

Edit Jan 21, 2008: You’ll probably want to setup daemonic to start mysql on system startup.

sudo daemonic enable mysql

Hopefully there aren’t too many typos/mistakes due to my poor notes. If you find any, throw up a comment and I’ll patch the post.

The only software I’m really missing right now in fink is nginx, but I’ll have more on that soon. :)

I’ve been a pretty happy user of MacPorts/DarwinPorts for the past couple years, and all was good. I could install all the UNIX goodness to run a rails stack and have most of the network/security apps I was used to from the Linux world. But, recently I stuck in a dynamic library situation with ImageMagick and the rmagick ruby gem that was causing me a lot of grief. So, I removed ports and my gems and started over, but still no dice.

In a perfect world, I’d have rolled back to the last working ImageMagick package and go on my happy way. Unfortunately, that doesn’t seem to be an option with MacPorts if you don’t have the old versions still compiled on your system. Of course, I didn’t because I naively decided to start from a blank slate (see above). Ultimately, I decided to try the out Fink before digging too deeply into how to fix the linking issue.

I’d used Fink for about a month when I first dipped my toe into the Mac waters, so I had some idea how the system worked. It’s based on some Debian tools like dpkg and apt-get, and offers both binary and source packages. Much like Debian, I had to immediately switch to unstable to get any sort of useful ruby install. Also, unless you can live in Candy Land and only need stable tree, I’d avoid using apt-get no matter how much your Debian/Ubuntu love makes you want to. The “fink” command line is really what you want.

And my favorite bit, is that I can rollback packages! Check it out:

It’s the 9th and last video in the series, but you can order a DVD through the rails envy site.

From a mailing list entry by William Davis, ::

sudo rm -rf \
/opt/local \
/Applications/MacPorts \
/Library/Tcl/macports1.0 \
/Library/LaunchDaemons/org.macports.* \
/Library/StartupItems/DarwinPortsStartup

Why? Well if like me you run into some strange OS X dynamic linking issues and want to reinstall all your ports, or if you want to try out fink and make sure you don’t end up hitting your old ports applications.

Go about 1/3 of the way in and watch the remove a person from the photo example. It’s not perfect, but it’s impressive how easy it is to do. I just tried it on the site, and it is really that easy to remove stuff from a photo. While it’s not undetectable, it definitely makes for a printable picture without that guy you didn’t invite to the party.

The 2nd to last video in the series. It speaks pretty well for itself.
