This TableDnD plugin allows the user to reorder rows within a table, for example if they represent an ordered list (tasks by priority for example). Individual rows can be marked as non-draggable and/or non-droppable (so other rows can?t be dropped onto them). Rows can have as many cells as necessary and the cells can contain form elements.

Can serialize the row ids for AJAX updates. Has a nifty ability to lock dragging inside multiple tbody's in the same table.

[2 cents] If you've got multi-column data you want to drag up and down, then serialize to your server, this looks great. Implementation seems thorough, docs are pretty good. Wish I'd had this for some arcane tablerow sortables I hacked together a couple years ago with straight javascript.

jGrowl is a jQuery plugin that raises unobtrusive messages within the browser, similar to the way that OS X's Growl Framework works:

Messages appear in a corner of the screen, then fade out. Can display 'strips' (for lack of a word) of sequential messages. Some people call this a toaster effect: like toast coming out of the toaster (and then more toast out of the same hole (hmm)).

[2 cents] Lots of options here...well explained, a good set of examples (but none for putting messages in the viewport bottom-right corner, which is where I'd probably use it). 7 releases so far, so it seems pretty active (though no dates listed and I didn't poke around). Definitely on my keeper list when the muse-case strikes.

The point: We often have to display large amounts of data on the web. Generally we show a table of values with headings and if we really wanted to get fancy we would use a picture of a graph. People like pictures. I like pictures. Why? Because it is far easier to interpret data when it is in visual form. However, creating a picture graph and updating it with new data can be a pain. In this tutorial, we?re going to use a jQuery plugin called Flot to create graphs on the fly.

[2 cents] Nice walkthrough for getting good results from the jQuery Flot plugin. Amazing piece of work, that plugin (but hey, I'm not all that mathy, so easily impressed). I'd definitely return to this if I were to want to dive into Flot a bit. Plus, NETTUS tutorials pretty much rock.

A simple, unobtrusive and customisable client-side method for easily embedding a Twitter feed into a web page:

[2 Cents] Relies on a twitter username, rather than a twitter search, to pull in the feed, which limits it. Of course, that'd be fine for someone who wants to pump their own tweets down into their page. No docs. Pretty sweet looking site that it's posted at.
