Add multilanguage support to Joomla site

Recently I’ve added multilanguage support to my Joomla site (Shall We Learn)

I was able to do so by following the following two resources:

2. Tutorial from Joomla YouTube Channel

My iOS Development Learning Plan

Since our family of four has slowly become an iFamily (two Mac Book, one Mac Book Air, one 21-inch iMac, two iPads, three iPhones, and one iPod), figure it is time that I should seriously consider learning how to develop iOS app. My thinking is that, even if I can’t make much off the App Store, at least I can make apps that our family and friends can use. And maybe one day, I could quit my day job and do iOS app development for a living, but that is for much much much later.

Here are what I would need

• To just develop using the simulator (comes with XCode)

Get a Mac (if you do not have any Mac, you could consider getting a MacMini which is affordable). Or if you do not want to buy or can not afford a Mac at this time, check out this instruction on how to Run Mac on Windows

Upgrade the OS to Mountain Lion

Download and install XCode 4.4 and up from App Store

• To test on a real device and to put app on the Apple Store

Sign up for the iOS Development program

Apple charges $99 for individual license and $99 for the company/team/organization license. If you would like to apply for your company, you need to provide documents to prove your affiliation with the company.

I have started and planned to continue following these steps:

To add a new jdk, I downloaded the jdk-6u-linux-i586.bin from the Oracle Java site. Unzip it

chmod 755 jdk-6u27-linux-i586.bin

./jdk-6u27-linux-i586.bin

It unzip it to a directory jdk1.6.0_27. I moved it to /usr/lib/jvm,

mv jdk1.6.0_27 /usr/lib/jvm

Then install the jdk1.6.0_27 as a Java alternative. The number 3 is for the priority.

update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk1.6.0_27/bin/java 3

Now if you do “update-alternatives –config java” again, you would see jdk1.6.0_27 got added as a new alternative. Type 3 and hit Enter to select.

Test publishing with Google Docs
