I heard the television show with Sheldon in it (I forget what it’s called, oh yeah, that’s right, Big Band Theory) on in the background and got to thinking about the cultural background of the main (male) characters: an ‘American’, an ‘Indian’ and two ‘Jews’.
Then I got to thinking about culture and for some reason particularly what I thought of Jewish culture. Basically they seem to me to value intelligence and seek wisdom; and I think that’s respectable.
Then I decided I’m hardly in a position to have an opinion because I have next to no experience in the matter being a relatively unworldly and untraveled individual, and that at any rate in general I cared about culture just about as much as I care about superstition.
I learned about the Mailman check_perms program today. Basically it reports on permission issues with the mailman database, which is good because I was having trouble with the permissions on the mailman database. Basically email for a new list wasn’t being added to the web archive because the right permissions weren’t in place to allow the mailman process to write there. Anyway, with the help of /usr/lib/mailman/bin/check_perms and the judicious use of “chgrp -h list” and “chown -R -h www-data:list” I think I managed to fix everything up.
Update: I had a problem after applying the above changes whereby I couldn’t access the web archive for Mailman lists anymore. But… I figured out how to fix it. Basically I added the www-data to the list group with the following command (and then rebooted):
Read the spec for Mailman 3.0. Looks like it will be pretty good. The feature that I’m interested in, and I’m annoyed I can’t do this with my current version of Mailman, is to be able to put a link to the web archived message in the bottom of the outgoing SMTP message. I.e. so there’s a link back to that message on the web in the message itself. Would be really handy for referencing. At the moment if I want a link I have to go to the web archive for the particular list and find it.
I want to post-process the output of an ‘ls’ command with ‘sed’ so that I can remove the ‘./’ prefixes that I can’t avoid going into the ls output (this is a result of using ‘find’ safely).
The thing is, if I pipe ls output to sed, then the default –color=auto setting applies and ls detects that it’s not talking to a terminal so doesn’t output colour codes. But I want colour codes, usually, so I need to change the ls command to use –colour=always, which I’ve done. This means I can have colour and also have sed format the ls output.
The problem is then what happens if I want to pipe my output to ‘less’? Then the colour code commands appear as garbage in the output stream. So, usually I want colour codes, and sometimes I don’t.
I’ve been through this process before (for older versions of MediaWiki than the 1.18 version I’m using at the moment, and things have changed) but yesterday I found myself following instructions for enabling support for mathematical equations in MediaWiki. So that’s up-to-date on my Morpheus (private) and Sixsigma (public at jj5.net) wikis (which are based on my jjwiki project). At the moment I have four wiki projects: bkwiki and bkdevwiki for Blackbrick, pcwiki for ProgClub and jjwiki for jj5.net. I also have another wiki project that’s not presently under version control called BBS for Blackbrick. I think I’ll roll the bkwiki, bkdevwiki and BBS projects into a single project (bkwiki), and the pcwiki and jjwiki projects into a single project (jjwiki) so that I only have two MediaWiki projects to maintain (for now). But, as usual, making things simpler demands more work… not sure when I’ll get around to that.
Today I learned about the SVNIndexXSLT Apache directive that lets you configure an XSLT stylesheet for your Subversion repository. Also found a whole web-site ReposStyle which makes me laugh — seems like overkill having a whole web-site for a repository stylesheet…
The SQL History feature of my phpMyAdmin setup wasn’t working, the history table had been configured correctly as ‘pma_history’ but there was no data being written into that table when I ran queries and the SQL History tab of the query window just showed a blank.
Eventually I figured out that in order for the pma_history table to be populated I needed to set the QueryHistoryDB setting to true. So I did that and now SQL History is working!
I think I’ve probably done this before (the links in my browser were marked as visited), but today I wanted to create a desktop/toolbar shortcut icon (with shortcut key) to a saved PuTTY session called “peace tunnel”. The “peace tunnel” opens an SSH session to a development server called “peace” and automatically configures a tunnel from port 80 on the localhost to port 80 on the server, so I can check on the progress of a web application under development.
I was configuring MediaWiki to allow uploads and was getting an error in the browser about the POST data being too large (“does not allow request data with POST requests, or the amount of data provided in the request exceeds the capacity limit.”). I had a look in the Apache error log and found:

So I did some research. I found this document, File upload size which suggested editing /etc/php5/apache2/php.ini which I did:
