After in-place upgrading this wordpress blog site to the latest 2.3 from 2.2.3 recently, I noticed a problem: auto-save generated an error at the bottom of the WYSIWYG editor window. I said ‘Google search’ turned up nothing, that was true for Google web search and Google group search. When I searchc against blogs, I found some wordpress.org developer discussion about this table being deprecated as of 2.3 release. wonder why auto-save code still uses it. Today, even ‘Google web search’ turned up a few entries. One of them are this deprecated post2cat table caused problem for UFW tag plugin. Read the rest of this entry »

Wordpress 2.3 was out this past Tuesday. I waited two days to be sure no major gotchas in terms of upgrade hurdles as well as security patches. Well, the in-place upgrade went smoothly. However, , I ran into a database problem about a missing table when editing the first new post, aka, this very post, though. Google turned up nothing!

Upgraded the site in-place this morning from wordpress 2.2.3 to wordpress 2.3, to get the following two new features. There are more new features, plus tons of bug fixes. Read the rest of this entry »

After three weeks use of the Trendnet TEW-432BRP wireless router, I experienced more serious problems.

• The unit resets itself randomly (every several hours or less than a couple of minutes). The computers/laptops behind it see ‘network disconnected’ then ‘network connected’, for both wireless and wired connections. No reasons were logged in the router log besides the fact it resets. All front LEDs go off dark then back on. Read the rest of this entry »

Last night, this site upgraded to the latest wordpress 2.2.3 from 2.2.2. Only one security fix was included for this release, to prevent a user from posting arbitrary HTML. Without this fix, “The user only needs to tamper data sent to post.php or page.php and add a field named no_filter with any value”.

Noteworthy on wordpress.org’s site about this release is apparent enhancements on pages of the changed files and bug fixed.  This is nicely done by ‘Trac’, a web-based software project management and bug/issue tracking system.  I never heard of Trac before. will check it out at http://trac.edgewall.org/.

Only the following changed files were replaced in-place for this blog site:

wp-includes/plugin.php
wp-includes/query.php
wp-includes/formatting.php

I recently upgraded and migrated a production instance of Confluence wiki. The task is interesting. The production instance of Confluence version 2.1.2 ran on a SELS 9 server with its ‘data’ directory NFS mounted. It uses external user management (CAS) with LDAP backend, plus a v8 DB2 database as the external database to store content of the wiki instead of the built-in suit-for-trial-only database. The new instance runs on RHEL 5 AS server with a v9 DB2 database.

My initial plan is to migrate the same old instance to the new data center, then upgrade whenever. Bossman overwrote the plan thinking it’d be a simple task to upgrade and migrate in one shot. Neither of us sees any feature in the new release as a deal-maker. I  guess common sense doesn’t always  win Read the rest of this entry »
