Mount SSH using MacFUSE

willcodeforfoo () — Sun, 21 Jan 2007 23:14:06 GMT

This will also list the voume in the Finder, thanks to the volname option (I think)

mkdir -p ~/mnts/formandfx

sshfs kmarsh@formandfx.com: ~/mnts/formandfx -oping_diskarb,volname=formandfx

Building curb under Mac OS X

willcodeforfoo () — Sat, 06 Jan 2007 00:44:55 GMT

Had a bit of a problem getting curb to work in OS X, but if you have the curl port installed, its easy:

sudo port install curl

cd src

curl -O http://rubyforge.iasi.roedu.net/files/curb/curb-0.1.0.tar.gz

tar -zxvf curb-0.1.0.tar.gz

cd curb-0.1.0.tar.gz

ruby extconf.rb --with-curl-lib=/opt/local/lib/ --with-curl-include=/opt/local/include/

ruby tests/alltests.rb

sudo make install

Freeze Rails to Edge RC2 via SVN Externals

willcodeforfoo () — Fri, 05 Jan 2007 22:08:41 GMT

So you've already frozen to RC1, but need to upgrade to RC2?

cd ~/Sites/railsapp

svn propedit svn:externals vendor

# An editor will pop up, change RC1 to RC2 and save

svn up

svn ci -m "* Upgrade to RC2"

<3 SVN Externals

Bonus tip: I'm a habitual 'svn stat'er, and this helped speed up the process:

svn --ignore-externals stat
