If you use Zoom controls from Accessibility system pref, and using an external monitor, you may have experienced *very* slow performance after upgrading to Yosemite.
One workaround is to set Zoom Style to “Picture-in-picture”.
Then, click “More Options” and click “Adjust Size and Location” to change the size of the Picture-in-picture.
From what I’ve read, 10.10.2 may solve this issue. Some user’s of the beta reported better performance.
Update January 30, 2015: OS X 10.10.2 came out yesterday and it did solve this issue!
tcpdump out ASCII characters and not see headers

When you touch the Messages title bar, then click somewhere else on your screen, the messages app will move as if you dragged it. Such a strange bug and it was not sadly addressed in 10.10.1. Reproducible on any Mac, every time. How this could slip past QA is beyond me.
After installing Amazon Music on my mac, I noticed this background task “Amazon Music Helper” running. I tried to kill it, it came back.
The fix I used was to remove execute permission on that file:
chmod -x /Applications/Amazon\ Music.app/Contents/MacOS/Amazon\ Music\ Helper
Then kill the process again and it shouldn’t come back.
I have bought music since then and find that all the features (that I use) work fine. This thing isn’t even needed!
Came across this technique to get a screen session started as another non-root user on system startup. You could have this command in /etc/rc.local or any other location that runs on system startup as root.
Also, it doesn’t have to just be at system startup. These commands could be used at any time by the root user to start a screen session for another user.
This command must run as root. I had best luck when providing full paths to the executable and optional file arguments (like if you are passing a conf file)
su - username -c "/usr/bin/screen -dmS screenname ./executable"
So, for example, to get irssi started as chris in a screen session named irc, You could:
su - chris -c "/usr/bin/screen -dmS irc /usr/bin/irssi"
You can then log in to the box as chris and resume the screen session that root started.

Here is a nice trick to add a proxy that your HTML5 application can use to connect to any remote proxy. Apache can proxy the API request while also injecting the CORS header Access-Control-Allow-Origin to that remote API reponse.
# Proxy for BaseServer
Header add "Access-Control-Allow-Origin" "*"
Edit your .bash_profile and add the line:
#For Java 7:
export JAVA_HOME="`/usr/libexec/java_home -v '1.7*'`"
#For Java 8:
export JAVA_HOME="`/usr/libexec/java_home -v '1.8*'`"
Animate.css is a wonderful CSS animation library.
On the website, animations are grouped by types – “Attention Seekers”, “Bouncing Entrances”, “Bouncing Exits”, etc.
What I present is a revised order with In’s and Out’s grouped next to each other. This gives a nice effect when cycling through all the animations.
