Finally got memcache working! I am compiling the steps here in case I need to do it again. First install libevent. This is a dependency to memcached, so need to get it. cd /tmp curl -OL https://github.com/downloads/libevent/libevent/libevent-2.0.17-stable.tar.gz tar -xvzf libevent-2.0.17-stable.tar.gz cd libevent-2.0.17-stable* ./configure make sudo make install Then install memcached. # Compile memcached utility cd /tmp curl -O http://memcached.googlecode.com/files/memcached-1.4.13.tar.gz tar -xvzf memcached-1.4.13.tar.gz cd memcached-1.4.13* ./configure make sudo make install At this point, if everything goes well, the memcache daemon should be ready to run.

Sometimes when you click on a qtip2 popup, you may want to close the popup somehow. For example, if your qtip2 popup contains a list of links, and clicking on the links will open up more popups. In that case, you would really want to close the previous qtip2 popup upon each link click. Well, here is how you can do that programmatically. $('.qtip:visible').qtip('hide'); Yeah, that’s it. Clean screen. Yeah~~~

My datatable was acting cool and all until I added a link to each integer element of a particular column. All of a sudden the sorting feature was acting weird. Before I had something like this 23 After adding a link, I have 23 It turns out after I added the links, the default sorting function is treating everything as string. So to fix that I will need to add custom sort function to explicitly tell datatable how I want to do my sorting. ...

Sometimes after working on a few TextMate windows, one of them will have its file directory tree drawer missing. I don’t know why this happens but to bring back the drawer, just go to the menu bar and click View -> Show Project Drawer. Also another tip is, if you prefer the drawer to come out from the right side but it always comes out from the left, all you need to do is 1. Hide the drawer 2. Move your TextMate window to the left side of your screen so there is not much space to display the drawer on the left 3. Show the drawer ...

It took me a while to find this out. If you need to change the default max width of qTip2, here is how. First set up a new style class. .my_width_setting_class { max-width: 1200px; min-width: 0px; } Then in the qtip style attribute, insert our newly created css class. style: { classes: 'ui-tooltip-wiki ui-tooltip-light ui-tooltip-shadow my_width_setting_class' } That will then override the default settings in jquery.qtip.css. ref: http://craigsworks.com/projects/qtip2/tutorials/styling/#dimensions ...

Too bad wp-codebox contains two divs namely wp_codebox_msgheader and wp_codebox, we cannot simply give the box-shadow to one single div. After playing with this a bit, here is my parameters. The css file is located at /your-wp-root/wp-content/plugins/wp-codebox/css/codebox.css. .wp_codebox_msgheader { box-shadow: 6px 14px 11px #808083; } .wp_codebox { box-shadow: 7px 10px 10px #888; } The overlapped area seems smooth with this setting. I also added bottom margin to the codebox, see if you like it. ...

Install Xcode first. You will need the one from the Mac App Store. You will need version 4.3 or above. Then install homebrew. Go to this link ( https://github.com/mxcl/homebrew/wiki/installation) to find the installation command. As of May 2012, the command is: /usr/bin/ruby -e "$(/usr/bin/curl -fsSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)" Then after the process finishes (it took like 30 seconds), run brew doctor This is just to make sure your environment is good to move on. If your Xcode is old you will get a complain here like the following: ...

When dealing with dynamic creation of DOM objects, sometimes you need to check if a certain element exists.
