Paolo Valdemarin: Starting today, we are distributing the Italian version of Radio. It took longer than expected to localize (have you ever noticed how much text there is in the help pages of Radio???), but now it's done.

I still don't know how many episodes this mini series will consist of, but today I'm focusing on the liveTopicsSeeAlso macro, which displays a list of related topics with each post.

If you look at the bottom of this post, as rendered on s l a m's home page, you'll notice the small type:

See also: liveTopics macros

Clicking on liveTopics or macros takes you to the topics index for s l a m, with an expanded entry for the topic you've just clicked on (takes a while these days, we're expecting transclusion to come to the rescue :-).

That is because the #itemTemplate.txt template file, responsible for the layout of each individual post, includes a line like this:

<%liveTopicsSeeAlso ( postnum:<%itemNum%>, htmlEnclosure:"span" ) %>

The first parameter, postnum, is actually a call to a standard Radio global variable, that returns the current post's identification number.

The second parameter, htmlEnclosure, specifies that I want my topics listed in a line which includes other elements - a permalink and a comments link. I achieve this result by enclosing the output of the macro in a 'span' HTML tag.

By default, liveTopicsSeeAlso encases its output in a 'div' HTML tag, which breaks the current line by creating a box-like effect around the topics list.

This is fine if you want your topics to stand out on their own, as demonstrated by multimedia mogul and html connoisseur Marc Canter in the top right corner of his posts.

I see that Marc knowingly uses another parameter, flDisplayInColumn, setting it to true to ensure that his topics are laid out in a stack, whereas the default false value displays topics in a space separated list, as on s l a m.

liveTopicsSeeAlso provides a bunch of other optional parameters.

• seeAlsoTag specifies the text to be used as a prefix to the list of displayed topics. The default value is of course 'see also'. You can provide an empty string (""), as Marc does, to prevent the display of any prefix.
• statusTag specifies the text to be used in the browser's status bar when the mouse hovers over a topic link. the text defaults to 'See more posts about: [the_designated_topic]'.
• htmlClass, htmlId and hrefClass provide the same services as their namesakes in liveTopicsHotButtons.

That's it for now. Next time, I'll probably play with liveTopicsGoogleJazz.

From the latest RHN alert: ... A read buffer overflow vulnerability exists in the glibc resolver code in versions of glibc up to and including 2.2.5. The vulnerability is triggered by DNS packets larger than 1024 bytes and can cause applications to crash.

This is potentially a bad one. More information on the CERT Vulnerability Note.

Jon Udell reviews NetNewWire Lite, the RSS reader of choice for all MacOS X users.

I found out that Brent supports OPML as a way to import and export news feed lists to and from both Radio and AmphetaDesk. Way cool !

NetNewsWire is very close to what a dream news aggregator should be. It's got a squeaky clean Cocoa interface. If you're running a Windows system (I heard you were quite numerous, surprisingly :-), and out of money to afford the switch, then you're out of luck too.

That is until Mikel and I can bring our activeAggregator to myRadio. Right Mikel ? :-)
