Solution:
$ brew uninstall freetype $ brew install freetype $ brew link -f freetype
ruby on rails – bundle reinstall
After an OS upgrade I needed to reinstall all the gems for my Rails project (well, I probably didn’t need to do it, but it seemed the quickest way).
Since I used RVM and only had one Ruby on Rails project I was working on, doing so is easy, though not intuitive.
To uninstall all the gems:
$ rvm gemset empty
Then install them the regular way:
$ bundle install
You might get an error that looks like this: “There was an error in your Gemfile, and Bundler cannot continue.”. Â If that’s the case, run:
$ gem install bundler
__rvm_cleanse_variables: function definition file not found
I started getting this error in OS X after I switched my Terminal shell from bash to zsh (with oh-my-zsh).
~/.rvm/scripts/initialize:50: __rvm_cleanse_variables: function definition file not found
To fix, run:
$ rm -f ~/.zcompdump
iOS: Make divs not have a shadow on touch
Similar to a previous Android issue, except this time for iOS. Â It’s not really a problem per-se, but it can make your UI look less clean. Â What happens by default in mobile webkit is that when you hold your finger on an element, a grey transparent box is overlayed on it. Â To remove this, use the following CSS property:
-webkit-tap-highlight-color:rgba(0,0,0,0);
What really matters is the last value in the 4 values, which sets the opacity to 0, in other words, makes it transparent.
OS X Brew – “Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master”
In the middle of a `brew update`, I killed the process with ctrl+c. Â This left the git repo in a broken state.
Please move or remove them before you can merge. Aborting Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master
To fix:
$ cd /usr/local $ git add . $ git stash $ git reset --hard
`brew update` should now work.
IE7 overflow: hidden is broken
If you’re having problems with overflow:hidden in IE7 or IE6, make sure you apply position:relative to the element, or overflow:hidden is ignored.
Client Side Javascript Error Logging
Karl Seguin just published a great short article on the why and how to log client side Javascript errors.  Read it here with some HN discussion here.
Update: Consider using Google Analytics to log Javascript errors.
Debug Node.js apps with node-inspector
If you’re writing code for Node.js, node-inspector is a must-have, and is far superior to Node.js’s built in debugger. Â What you get by using it is a Javascript debugging tool nearly identical to Chrome’s Javascript debugger, but for your Node app.
To install it, just use npm:
$ npm install -g node-inspector
Since you’ll be connecting to node-inspector via your browser, you’ll need to spool up the node-inspector server as so:
$ node-inspector &
Finally, run your app in –debug mode:
$ node --debug app.js
Connect to http://127.0.0.1:8080/debug?port=5858 and you’re good to go!
This setup description and more info can be found in the README.
Safari 5.0.5 won’t play HTML5 video
Trying to play HTML5 video in Safari but getting a blank video screen? Â Possibly with 0:00 second video length?
I posted the solution over on SO but basically this head scratcher can be solved by using a full URL for the <video>’s src attribute. Â If you don’t, Safari doesn’t even try to fetch the video.
I think this bug is only present in very specific versions of Safari (possibly just 5.0.5).
