Offloading SSD I/O Traffic by Creating Symbolinks

I’ve upgrade my 3.5 yo laptop to SSD for a month. I tossed away the CD-ROM and installed the HDD drive with a caddy. BOOM!! The performance is absolutely fantastic. And I can still keep all the things around in HDD drive.

And I hear lots of stories that SSD has its lifespan. The more you write on it, the shorter its life.

I’m on Windows 8 and I found most of the things on this post useful.

The one I like the most is mklink. It’s super useful. I used it occasionally whenever I want to share some resource across different projects. But anyway, the command is very easy. Let’s take Chrome as example. As we know, Chrome is greedy on cache – tons of writes – and I browse internet more than I breath. All right, that’s a bit exaggerating, but you get the point. So I decided to move it.

mklink "C:\Users\Mike\AppData\Local\Google\Chrome\" "D:\Users\Mike\AppData\Local\Google\Chrome\" /D

It’s pretty simple and handy. I did the same to Windows Search Indexes and a bunch of other folders.

Installing CyanogenMod on Nexus S

I’d like to play around Cordova to build cross platform mobile application. So, I took out my 3 years old Samsung Nexus S – the 1st phone I bought by the time I came to Australia. Tried to install CyanogenMod 11 which is based on Android 4.4 KitKat and design for better performence on low-end devices.

So I followed the instruction here. I’ve downloaded the rom and Andriod SDK. Managed to unlock the phone and then stuck at pushing the room via sideload method. It keeps complaining the protocol issue. And no luck with push method as well for very generic error.

So I asked the Google which led me to upgrade the rom manager. So I downloaded the one from this site. Then did the following to flash the manager

fastboot flash recovery recovery-clockwork-

Started over again with sideload, still with some random protocol issue. But this time, I was able to mount /data folder and ran the following command to push the rom.

adb shell "mkdir /sdcard/0/"
adb push /sdcard/0/

After the waiting for the installation. Reboot the device and here we go. New OS was installed.

Multi-user WordPress Hosted by IIS

I’ve been playing WebMatrix for open source projects. For Say you can start a WordPress instance with just a few clicks. It installs all the pre-requisites like MySQL database and PHP. Then downloads WordPress and bootstraps the configuration. All happens within just a couple of minutes. Which is amazing.

Everything goes well until you start to enable multi-site aka Network feature. The setup requires the site hosting on port 80. So I have to change the IIS Express binding and put a new entry to my local hosts registration. And I have to start WebMatrix as administrator.

This seems to be fine and it asks to update the web.config with new URL rewrite. But when I visit the sub-site. The address is not able to be resolved. After I asked the Dr. Google which led me to this post. There provides a better rewrite rules. Now everything works like a magic. ;)

AngularJS, Protractor, Visual Studio! SUPER DRY!!

I AM A .NET Developer. Visual Studio is the trench that I dig every day. AngularJS is the primary weapon that I use in the frontend. I want to have Protractor as my first aid kit which doesn’t play nicely without Node.js. But it’s all right, I can tame it!

Update: you might be interested in this sample project to dig in quickly. It contains a tiny AngularJS app and a few test cases.

Let’s shave the yak

Do you know that Node.js Project is actually a Node.js flavoured ASP.NET project?

  • Update selenium standalone server
    .bin\webdriver-manager update

  • Start selenium standalone server
    .bin\webdriver-manager start

  • Run test specs
    .bin\protractor protractor.conf.js


  • Include node_modules\protractor\lib\cli.js into project and Set it as Node.js Startup File
  • In project properties, configure Script arguments as protractor.conf.js


  • taskkill /f /t /im chromedriver.exe
    Sometimes you are stuck while debugging because previous chromedriver session was not terminated properly. Use this to kill all chromdrivers that lurks around.

  • Testing out Protractor interactively
    The tool provides a REPL-ish way to test selector.
    It helps to test while writing the test. Instead of test after you finish the test spec.

Sublime Code Preview UI

Excitingly, my package get merged into sublime package community list last weekend. And within a week, I got a pull request from Carl Furrow. Carl says it is the beauty of the open source. Anyway, it does make me feel so social in the bits and bytes world ;)

This package is totally inspired by Visual Studio Web Essential, which has a awesome code preview window for CoffeeScript, TypeScript etc. I really like feedback it provides as I am writing the code. So I ended up with this package provide similar code preview tool for Sublime Text.

The source code is hosted on github, feel free to contribute new features to the project!

#Appfest Sydney

#appfest sydney

Just spent 3 days join in the #Appfest Sydney since last Friday. Got a little bit tired. But it’s absolutely fantastic. This event is about windows 8 app, windows phone app and windows azure.

As I join the session of building apps for two platforms, talked by Microsoft technical evangelist, Nick Hodge. He is funny, and his style is somewhat like Scott Hanselman to me.

Shane Morris shared very good slides at keynote session for designing windows and windows phone app.


What I got from this 3-day event? A lot of freebies, fantastic catering, and most of all, the tips of designing and building windows, windows phone apps.

Mentors are very helpful. So there are many good ideas generated. I really enjoyed. Thanks for organizing such an event. And I decided to start my journey of building windows apps.

Steps To Big Data: Hello, Cascading

In previous post Steps To Big Data: Hello, Pail, we have defined our fact model and shown how to use Pail to store out data. What is fact model?

A Fact Model, as we see it, structures basic knowledge about business operations from a business perspective. “Basic” means that the knowledge it represents cannot be derived or computed from any other knowledge. It that sense, a Fact Model is a crucial starting point for developing more advanced forms of business knowledge, including measures and rules.

As described above, fact model cannot be derived or computed from any other knowledge. In other words, its purpose is to generate data. The process of generating data from fact model could be illustrated as below.

Cascading supports to create and execute complex data processing workflows on top of Hadoop using any JVM-based language(Java, Scala, JRuby, Clojure, etc.) Most cascading related libraries are in the Maven Repository

We are going to use cascading to count users’ actions.
