Install R in Ubuntu is extremely easy if you don't meet any exception, but if you meet, then you'd better be a very advanced linux user :-)

Very thanks to TopGeek and Capital of Statistics given this R lecture, as part of Seven Languages in Seven Weeks, the R language is more unique than the original Pragmatic book language Prolog.

The answer for Python Code Dojo Class Two, which I attend today as seven language in seven week hold by Shanghai TopGeek.

After I switch my blog to Octopress, I realize that compare with the Google App Engine, the Github gh-pages hosting service is much slower (10 times compare with GAE ping value, 6xxms vs 6xms)

So I believe it's better to hosting the static blog file to GAE, switch to GAE also enable server side script as a bonus if you didn't care about portable, which is the most reason I using Octopress.

There is tons of good installation guide for Rails, but I still think it's reasonable to log my installation here as I will change it time to time to make this blog ever better.

Just very glad to annource that I just finishing switch my blog from Micolog to Octopress.

Micolog is a Google App Engine based blog, when I decide to use at Auguest 2011, the GAE price model is not so tough and Micolog is quite good for personal tech blog choose.

But after GAE price policy changed, I meet quite a lot Datastore Reads quota over Free budget, which lead almost the original blog inaccsible 3~4 hours everyday.

At same time, in the passed year, my favor language also change from Python to Ruby, so to rebuild the blog using a Ruby language solution, the Octopress is more good choose for me.

The most unique feature of Octopress is it have no bandend DB require, all the blog content is purely static html file, which will be generate before deploy based on your markdown blog file. That make Octopress requirement very very minimal compare with Wordpress/Micolog. Basicly a static page site is already enough, so it make possible to just deploy this blog on Github directly.

Hoping for a long time, I'm not worry about the blog facility anymore.

I use the Gmail as my personal primary email, at the same time, my company using Exchange 2010 as email server, one of the feature I'm quite missing from my gamil is the calendar auto push similar to Exchange server. But I suddenly found in fact Gmail also provide the Exchange Active Sync support and here is how to enable it, I using Android account as example.

I use the Windows 7 and after you install Android SDK Tools, you can locate the USB driver at [C:\Program Files\Android\android-sdk\extras\google\usb_driver](file://C:\Program Files\Android\android-sdk\extras\google\usb_driver)

You need to modify the file android_winusb.inf (may need to save to Desktop and move to original folder due to Windows 7 protection), Add below line after section [Google.NTx86]

;HTC Incredible
%SingleAdbInterface%        = USB_Install, USB\VID_0BB4&PID_0CAC
%CompositeAdbInterface%     = USB_Install, USB\VID_0BB4&PID_0CAC&MI_01

If you use the x64 version, Also add below line after [Google.NTamd64]

;HTC Incredible
%SingleAdbInterface%        = USB_Install, USB\VID_0BB4&PID_0CAC
%CompositeAdbInterface%     = USB_Install, USB\VID_0BB4&PID_0CAC&MI_01

After you modify the file, you can in Device Manager and update the Andriod Device driver by manually click the button "Update Driver Software" and point to the folder of android_winusb.inf by install it.
