Kubuntu 9.10 (karmic) 64bit firefox java plugin

For some unknown reason the (K)Ubuntu developers did not update the Java plugin for firefox after jaunty (yet?).

The version that Karmic (9.10) pulls out of the multiverse repository is still jaunty's (9.04).

So when you try:

apt-get install sun-java6-plugin

you'll get something like

   Reading package lists... Done
   Building dependency tree
   Reading state information... Done
   Some packages could not be installed. This may mean that you have
   requested an impossible situation or if you are using the unstable
   distribution that some required packages have not yet been created
   or been moved out of Incoming.
   The following information may help to resolve the situation:

   The following packages have unmet dependencies:
     sun-java6-plugin: Depends: sun-java6-bin (= 6-15-1) but 6-16-0ubuntu1.9.04 is to be installed
   E: Broken packages

Duh.

Actually if you have the Java Runtime Environment (JRE, package name sun-java6-jre) installed all files needed are already present.
Just not put in the right place on the filesystem.

So, run:

sudo apt-get install sun-java6-jre # install JRE if needed
sudo ln -s /usr/lib/jvm/java-6-sun/jre/lib/amd64/libnpjp2.so /usr/lib/mozilla/plugins/

This will install the JRE (if it's not already installed) and will symlink the firefox plugin for java in place so that it'll be found after a browser restart.

Seredipity default event_s9ymarkup plugin breaking URLs that contain underscores

The default Serendipity mark-up plugin (event_s9ymarkup) currently breaks URLs that contain underscores.

http://en.wikipedia.org/wiki/Statler_%26_Waldorf

will end up

http://en.wikipedia.org/wiki/Statler%26_Waldorf

because of a faulty regex. Garvin Hicking does not really want to fix this. (See this s9y support forum article for arguments pro/contra fixing it). So if you encounter this problem, your options are:

replace _ in URLs with %5F (aka manually urlencode it)
remove the plugin or disable it
patch the plugin

Patching is basically changing

plugins/serendipity_event_s9ymarkup/serendipity_event_s9ymarkup.php:

$text = preg_replace('/\b_([\S ]+?)_\b/','\1',$text);

$text = preg_replace('/\ _([\S ]+?)_\ /',' \1 ',$text);

If you want to be writing things like "Haha[lol]" (which I have no real use for ...), extend the "\ " with whatever you'd like to be o.k. to delimit bolded words beyond blanks. It should only be symbols that are not valid in URLs (so none of "$-_.+!*'()," which are all valid in URLs according to RFC 1738).

You may also want to consider replacing one underscore ("_") with two or more ("__") to make the detection, that you actually wanted to write bold text, more reliable.
