Autarchy of the Private Cave

Since some WP release, the comment author’s link in comments is broken – it has ‘ external nofollow’ attached straight to the href attribute (which breaks the link).

I assume that the problem is caused by Google Analytics, namely the “track outgoing clicks” feature (as recalled, might be inaccurate feature name). “Track outgoing links” adds some JavaScript code to all outgoing links, and that script has tick characters like this one ‘ which, incidentally, are also used for delimiting the values of comment anchor tags.

Two most common reasons (and fixes) for the MySQL server has gone away (error 2006) are:

1. Server timed out and closed the connection. How to fix: check that wait_timeout variable in your mysqld’s my.cnf configuration file is large enough. On Debian: sudo nano /etc/mysql/my.cnf, set wait_timeout to at least 600 seconds (you can tweak/decrease this value when error 2006 is gone), then sudo /etc/init.d/mysql restart. I didn’t check, but the default value for wait_timeout might be around 28800 seconds (8 hours).
2. Server dropped an incorrect or too large packet. If mysqld gets a packet that is too large or incorrect, it assumes that something has gone wrong with the client and closes the connection. You can increase the maximal packet size limit by increasing the value of max_allowed_packet in my.cnf file. On Debian: sudo nano /etc/mysql/my.cnf, set max_allowed_packet to to something like 64M (you can tweak/decrease this value when error 2006 is gone), then sudo /etc/init.d/mysql restart.

If you get MySQL server has gone away (error 2006) when using MySQL ODBC driver – give this hint a try.

Update: as of FireFox/IceWeasel 3.0.14, this bug appears to be fixed.

When right-clicking many links in FF3/IW3, it quite often happens so that a random action is performed instead of opening the context menu (bug report).

One of the solutions work-arounds (suggested by Andre Pirard) is to slow-right-click, that is to hold the right mouse button down until the menu actually appears, then – and only then – release it. Or, you can even slow-right-click, move the pointer over the desired menu item, and then release – that will perform the desired action in a single long right click (instead of more common single right click with a following single left click.)

Alternative workaround (found at the bug report page): install the mouse gestures add-on, and restart firefox. Tested: works for me.

This bug/behaviour is otherwise unsolved.

Update: the same solution seems to still apply to dotProject 2.1.2; the post instructions have been modified for dP 2.1.2.

Update 2: fsmullin suggested a method to fix a similar error in index_table.php, the files_count_max cannot be found error when you click the FILES tab/menu item. His suggestion is now incorporated into the post.

In one of my recent posts about project management software I stated the desire to extensively test dotProject 2.0.4. However, many shared hosting providers appear incompatible with dotProject: the right to CREATE TEMPORARY TABLES in MySQL is not granted, but is needed by dotProject.

Here’s sample error (2.0.4):

query failed(CREATE TEMPORARY TABLE tasks_sum SELECT task_project, COUNT(distinct task_id) AS total_tasks,
SUM(task_duration * task_percent_complete * IF(task_duration_type = 24, 8.0, task_duration_type))/
SUM(task_duration * IF(task_duration_type = 24, 8.0, task_duration_type)) AS project_percent_complete FROM `tasks` GROUP BY task_project)

For 2.1.2, sample error would be:

Table ‘tasks_total’ doesn’t exist

I tried looking for solutions, and here’s what I found…

In Internet Explorer for Windows (tested with version 6 SP2), if you write CSS code similar to this:

and put your "floatbox" inside a container (such as DIV), you will actually see 200px of the left margin instead of the expected 100px. This problem is known as "IE margin-doubling bug".

In this post I collected solutions you can use to avoid this problem. The solution I'd recommend is at the end.
