Moved to Rackspace Cloud

KahWee — Mon, 08 Feb 2010 03:02:08 +0000

A couple of days ago, I encountered a database corruption. One sentence: My access log grew so huge it took up 100% of the disk space; MySQL can no longer write the database files and a few tables got corrupted.

Okay I cheated on the one sentence.

Rackspace Cloud has similar build as Slicehost (my previous host). I moved a few of my blogs over. Currently Slicehost is like an expensive DNS server. That said, Rackspace Cloud is cheaper than Slicehost. Slicehost is a subsidiary of Rackspace. Well anyway, if you do like to use Rackspace and would like to make my day, use my referrer code ‘REF-KW’ without quotations. It gives me some rebate, I think.

Addons.Mozilla.org is currently using CakePHP but they will no longer in 2010. They decided to adopt Django. (Source: Micropipes.com)

Bye Apache, Hi Lighty

As planned, Apache is no more. Say hi to Lighty

Made a few silly mistakes along the way and almost accidentally deleted my folder of pictures even. Things got a little more responsive. I haven’t used any caching solutions for WordPress. Caching is going to be tough work.

I just let PHP CGI spawn happily:

Lighttpd don’t exactly take up a lot of resources too.

Tonight I’ll fix the server

It’s been requiring almost a daily restart. I think it’s probably MySQL or Apache’s fault. Or perhaps it’s just my fault for being a miser not wanting to pay for more. Either way, I’m going to fix it. So far, I’m done with the virtual hosts. Lighttpd isn’t as hard as I thought. PHP is working fine already. I’m still in the midst of testing if WordPress works. Once I’m done with that, it’s “sudo apt-get remove apache2″.

Character encodings are important!

KahWee — Sat, 03 May 2008 14:11:06 +0000

I’ve been reading about character encoding recently, in particular to the various unicode standards. I’ve been rather pissed off with setting up the wrong collation in MySQL, I just realized that at my other blog, I have posts that are in utf8_unicode_ci, latin1_general_ci and utf_general_ci. This is what you get when you migrate database blindly without knowing what is character set. I regret not reading enough. Now I set everything to utf8_general_ci.

Anyway, something about another encoding set – GB2312 – caught my attention.

Here’s a trivia, the older Chinese encoding GB2312 cannot write the former Chinese Premier Zhu Rongji’s name. His name has often appeared as 朱熔基. Zhu disapproves of this and prefers the correct version, 朱镕基.

Later, GBK is established and his name finally can be written correctly. GBK is an extension of the GB2312 character set for simplified Chinese characters, used in the People’s Republic of China.

Well, another trivia about him:

Zhu is known for his technical intellect. In 1997 at a state banquet in Australia, Zhu left for the bathroom, and was gone quite a while. Concerned security staff finally went off to find him. He was in the bathroom, studying the water-saving dual-flush system which he had just disassembled. As a hydrologist, Zhu grasped the impact such water savings, multiplied by China’s huge population, could have on China’s infrastructure. (Source: Wikipedia)
