I am making a small improvement on TwitterPress to make it support Microformats hCard.
I tested with the Operator toolbar and Microformats bookmarklet, it looks good:
I will release an upgraded version of TwitterPress later. Sorry, I was too busy to upgrade TwitterPress, so it was still remain on preview version 0.1

I just upgraded my WPMU from previous 1.2.x to the current 1.3, so far so good, seemed everything is smooth.
Here is the steps I followed:
1. Backup MySQL Database. I finally didn’t use the backup data after all since no problem on the upgrade.
2. Decompress the WPMU in a new directory. I didn’t touch the old version, so just in case anything went wrong, I can quickly switch it back.
3. Copy wp-config.php and .htaccess from old installation to new one. Copy wp-content directory from old installation. (Notice that old files appeared in wp-content/mu-plugins directory will not required in new version since they have been moved to other place, only copy the plugins you installed in that directory. )
4. Switch apache’s virtual host setting and point to new directory.
5. The new installation should already work now, login to the management interface, run “site admin/upgrade”, then check if any plugin compatible problem.
I have no problem to upgrade after all.

This is a 0.1 preview version, I was suposed to implement more features and enable more options inside it, however some plan changed and I suddenly become very busy these days.(Life is random, isn’t it?) So I have to release this preview version out just in case I was sucked in some works so TwitterPress may be delaied too long.

I have installed an unfinished TwitterPress in my Chinese blog (in Chinese) for test, because most of my twitter friends speak Chinese…
Hopefully I will finish it in 1 or 2 days and release the first version. 
Here is a progress from an idea to the real thing…
idea: Twitter+wordpress = SNS enabled wordpress
prototye: A twitter based social network inside wordpress
0.1 (alpha) : this post…
0.1 (beta) : maybe tomorrow…

I am now working on an experiment: a wordpress plugin to turn wordpress into a social network, you can have friends lists, the latest updates of friends, the lastest posts of friends in your wordpress page.
This social network is based on Twitter, and it was inspired by AlexKing’s TwitterTools.
I will tweak it these days, when it’s ready I will release it so every one can play with it.
The original idea was here: Twitter+wordpress = SNS enabled wordpress

Today I spend about 10 minutes to wrote a small javascript code and wish to release it in my blog, then I spend almost 2 hours to find out how to get rid of boring WPMU(Wordpress Multi Users)’s post html tags filtering.
I searched across the Internet, lots of people are asking how, very few information are helpful. The official “how to use Javascript” is actually missleading. It suggest to install “text-control plugin”, turn off rich editor are totally useless in WPMU.
Finally I got a simple solution by hack some code:
edit wp-include/kses.php, found “Post filtering”, and simply comment out a line:
// Post filtering
//add_filter(’content_save_pre’, ‘wp_filter_post_kses’);
UPDATED (Jan 10, 2008)
Joe in his comment point out the better solution, thanks Joe!
At around line 742 of kses.php, do the following commenting out:
function kses_init_filters() {
// Normal filtering.
add_filter(’pre_comment_content’, ‘wp_filter_kses’);
add_filter(’title_save_pre’, ‘wp_filter_kses’);// Post filtering
// add_filter(’content_save_pre’, ‘wp_filter_post_kses’);
// add_filter(’excerpt_save_pre’, ‘wp_filter_post_kses’);
// add_filter(’content_filtered_save_pre’, ‘wp_filter_post_kses’);
}This allows you to only stop filtering of the POST, but the comments still get filtered.

AlexKing’s Twitter tools is a great wordpress-twitter mashup plugin:
Twitter Tools
This plugin creates an integration between your WordPress blog and your Twitter account. Pull your tweets into your blog and create new tweets on blog posts and from within WordPress.
Download | README | SVN Repository
Latest Release: Version 1.0, 2007-05-07.
However this version TwitterTools have some problem in my Chinese blog, all Chinese characters are displayed as “???”, that should be an encoding problem.
After I investigate this problem, I found it because my MySQL database’s character set is not UTF-8 unicode, so TwitterTools created a table as default charset, that cause the problem. Why wordpress’s posts show correct encoding? I looked through wordpress’s code, and found that they will force create tables in correct encoding and won’t just use default one.
After I pull some code from wordpress’s wp-admin/upgrade-schema.php and plugin TwitterTools.php, problem gone! (All previous data in the table remained problem, I just delete that table and re-activate Twitter tool again. NOTE: Deactivate TwitterTools seemed not delete that table, so you need to delete yourself. )
I will email Alexking the update and he may put this changes to his next version, but before he change it, I release an non-official version here:

Yesterday, I decided to host my feeds with FeedBurner like many bloggers do. There is no problem to create a feed of this blog, however when i tried to create a feed for my Chinese blog, FeedBurner refuse to continue because it said that my feed can’t be validated:
http://feedvalidator.org/check.cgi?url=http%3a%2f%2frobertmao.com%2ffeed
Sorry
This feed does not validate.
line 167, column 77: ‘utf8′ codec can’t decode bytes in position 10676-10678: invalid data (maybe a high-bit character?) [help]
…
In addition, this feed has issues that may cause problems for some users.
We recommend fixing these issues.line 115, column 21: description contains bad characters [help]
After I check the error message, it seemed that the problem is from my blog post content, I did copy/paste some text from some other website in some of my posts, but how could I know those text may contain invalid UTF-8 char? It seemed to be a serious problem.
I can’t believe that why FeedBurner can’t handle this, since my feed can be read correctly in Firefox, Google Reader, Bloglines, and a bunch of other RSS readers, aggregators. But since it can’t handle, and my feed did have problem to pass validation, it’s my job to fix it.
I wrote a very simple wordpress plugin to fix this problem, it will correct all possible invalid UTF-8 data inside the feed content. After I activate my plugin, my feed can pass the validation correctly, so I have no problem to use FeedBurner any more.
I release this simple wordpress plugin here, just in case someone else have similar problem as I had.
Download: wordpress plugin to fix the invalid UTF-8 data inside the feed
Version: 1.0
Install: Download and unzip the file in your wp-content/plugins directory, and then “activate” the plugin in your admin panel’s “plugins” menu.

I wrote a new simple wordpress plugin for my own use, but I guess maybe someone else may need it, so I release it here.
This plugin is very simple, it put a google search box right behind your blog post, and it fill this post’s title in the search box for you. With this search box, you and your reader can search the related information easier, they no longer need to open a window, browse to google and type in some words… now all they need is click the button.
The search box will only show up in single post display, it will not show in front page, category, search results, …
This version I only add standard google search form, in the future, if required, it can be configured to support site search, or google co-op search, and use user’s Adsense account to make some money from the search result. If anyone think such feature is important, let me know I may add it.
Download Here: Wordpress Plugin - Add Google Search box to blog posts
Version : 0.1
Install: uncompress it in your wordpress plugin directory, and activate this plugin.
