While playing with Ubuntu on a VirtualBox hosted by OS X Mavericks, Vim seems much faster than it being in iTerms2. How could that be? So I took the following steps to test things out: <ul> <li>Installed exact configurations with Vundle on the VM.</li> <li>Vim in Terminal.app</li> <li>MacVim with GUI.</li> </ul> Nope, Vim is still more responsive on Ubuntu. In fact, text input seem more responsive on this VM than the host OS in general! I thought I came to the light switching to OS X after using Linux as desktop for years, and now this? <a href="http://developer.android.com/reference/android/util/Log.html#wtf(java.lang.String,%20java.lang.Throwable)">WTF</a>? Defeat and confused, I went to the Internet, and found <a href="http://stackoverflow.com/questions/4489885/how-can-i-increase-cursor-speed-in-terminal">something close to an answer</a>. Under System Preferences-Keyboard, drag the two slide widget ("Key Repeat" and "Deley Until Repeat") to the right most. Suddenly, Vim become faster! Turns out, key repeating is very important for Vim users.

Turns out, it's not as straight-forward as one would think. Using <code>homebrew</code> will not work: <pre><code> brew install PyQt5 --with-python3 </code></pre> This is because of <a href="https://github.com/Homebrew/homebrew/issues/25735">an unfortunate choice</a> made by the homebrew maintainer regarding Python 3. So installing from <a href="http://pyqt.sourceforge.net/Docs/PyQt5/installation.html">source</a> is the way to go. Following the installing instruction, you would download and install <a href="https://web.archive.org/web/20140410074945/http://pyqt.sourceforge.net/Docs/sip4/installation.html">sip</a> first, the install <a href="http://pyqt.sourceforge.net/Docs/PyQt5/installation.html">PyQt5</a> itself. Except that's not enough. When you run <code>python configure.py</code>, you see this error: <pre><code> error: Use the --qmake argument to explicitly specify a working Qt qmake. </code></pre> It's pretty self-explanatory. <code>qmake</code>, the build tool for qt is needed here. Install qt5 with homebrew and proceed: <pre><code> brew install qt5 </code></pre> Afterwards, you should be able to import <code>PyQt5</code> in a Python 3 REPL.
