Just bought a iPod Touch 32G edition. It has safari browser. I use it to browse one of my Blog powered by WordPress. The text and images are so small. I know I can enlarge them by two fingers, but it is still has width problem.

I thought it must be some plugin can do it to make a blog mobile.

I did a google search and find this one: WordPress Mobile Pack
I install it on the backend of WordPress.

Just a few clicks to config it and it works.
I went to my blog. Wordpress detected my browser and knew it is from an hand held device. So it gave the mobile version of Blog.

It is perfect. I don't need to setup an separated domain for mobile device. Just like some site named as m.example.com. The regular site domain is www.example.com.

The configuration steps as below.

I have an WordPress MU installation on my VPS. I am always looking for the way to improve the performance.

I found WordPress has a Memcached plugin here.

The WPMU I installed is the latest one, v2.9.1.1.

The Memcached plugin is v2.0.1.

Installation instruction said:

1. Install [memcached](http://danga.com/memcached) on at least one server. Note the connection info. The default is `127.0.0.1:11211`.

2. Install the [PECL memcached extension](http://pecl.php.net/package/memcache)

3. Copy object-cache.php to wp-content

I have memcached installed correctly, which I used for MovableType either.
I did copy object-cache.php to wp-content.

The problem is when I add a page in Wordpress, it is not shown in the list of page links. The page is shown as usual.

I thought it is cache problem.

To keep your WordPress safe, use WordPress built-in upgrade facility.

Yesterday a vulnerability was discovered: a specially crafted URL could be requested that would allow an attacker to bypass a security check to verify a user requested a password reset. As a result, the first account without a key in the database (usually the admin account) would have its password reset and a new password would be emailed to the account owner. This doesn't allow remote access, but it is very annoying.

It is so happy to know that WordPress 2.8 released tonight.

The most important change is to make WordPress faster. I like it.
Find more information about the release here..

You can download it here for free.

I will find time to upgrade my installation of WordPress.

I saw a very strange comment in this blog, which is hold for review.

Website: ' AND 1=0) UNION SELECT 1 FROM wp_users WHERE user_login='admin' and substring(reverse(lpad(conv(substring(user_pass,8,1), 16, 2),4,'0′)),4,1)='1′ /* (IP: 124.217.250.190 , svservers.com)

It is same as what is mentioned Attack of the Wordpress-Hacking Spam Trackbacks.

The stupid spammer or hacker try the wrong Blog platform. I am not using Wordpress. It is MovableType.

It is a big news in WordPress user group. WordPress 2.5 released.

To upgrade you previous version, you have to follow the upgrade guide here.

If you are same as me, have a WordPress installation on Dreamhost, it will be very easy to upgarde. Just One-Click.

Let me go through the some new features in WordPress 2.5.
User Features

• Cleaner, faster, less cluttered dashboard


• Dashboard Widgets


• Multi-file upload with progress bar


• Bonus: EXIF extraction


• Search posts and pages


• Tag management


• Password strength meter


• Concurrent editing protection


• Few-click plugin upgrades


• Friendlier visual post editor


• Built-in galleries

Dreamhost's Newsletter mentioned that the One-Click feature is improved.
WordPress One-Click is easier.

I do not try the brand new easy install. I just use it upgrade feature.

It is very fast and easy. Just click the Upgrade to 2.3.3. The plugins are still OK.
No other operation needed.

Use Saving code G2SAVING when sign up Dreamhost, you can save $50 and get 1 extra FREE lifetime domain registration.

Another security upgrade is out for WordPress. This one is fairly urgent, as it allows other members of your blog to "hijack" posts not written by them.

From WordPress Development Blog.

WordPress 2.3.3 is an urgent security release. If you have registration enabled a flaw was found in the XML-RPC implementation such that a specially crafted request would allow a user to edit posts of other users on that blog. In addition to fixing this security flaw, 2.3.3 fixes a few minor bugs. If you are interested only in the security fix, download the fixed version of xmlrpc.php and copy it over your existing xmlrpc.php. Otherwise, you can get the entire release here.

Please upgrade to the latest version as soon as possible.

I have an installation of WordPress for one of my Blog. It is running over one year.
For WordPress, I have something to record related to the tag, the most important feature of Web2.0 or Blog.

As every WP fans know, WordPress is V2.3.1 now. It is free for download, and Open Sourced.

The embedded tag system of WP 2.3.1 is still not good enough. So I try to find a better one, not the best one.

Simple Tags is popped up into my eye. The latest version is 1.2, works on Wordpress 2.3.x. That means it is WordPress 2.3.x native plugin.

To install it is very simply, I don't want to repeat the readme file of the download package. You can find it.

To use it, is also very easy.
I'd like to list some feature I do like.

1) Suggested tags
2) Mass Edit Tags
3) Related posts
4) Tag cloud
5) Post without tags

At the end of this post, the site I mentioned in the beginning is Self-Study Resource.

Now I want to upgrade Dreamer's blog to WordPress 2.2.1 from 2.2.0.
This blog is hosted on Dreamhost.

I'd like to keep the record of upgrade.

1) Backup your database.
Dreamhost backup the MySQL database every day. So if you have no post in the past 24 hours, you don't need to do a manual backup through PHPmyAdmin.

2) Backup ALL your WordPress files in your WordPress directory.
Just ssh to the server, and run the command to backup all files.

tar -cvzf dreamer-2.2.0 dreamer.g2soft.net

3) Deactivate ALL your Plugins.
I sign in as administrator, and deactivate all plugins.

4) Download and extract the WordPress package from http://wordpress.org/download/.
Download the 2.2.1 package, I downloaded zip file and uncompressed it.

5) Upload all filles to the Server

6) Run upgrade.
http://www.mydomain.com/wp-admin/upgrade.php
There is no database update needed.

7) Activate the Plugins I used before.

Done.
