As usual with things like this: a decent client library that's at least somewhat up-to-date (official or no) goes a long way to helping you decide which [x] provider to use. In this case: SMS gateways that send to the UK.

"This is all very preliminary, but here is a first pass as a Processing Kinect library." Ooh.

"Simple javascript (+backend) library for web-annotation". Looks really good.

"gRaphaël’s goal is to help you create stunning charts on your website. It is based on Raphaël graphics library." And that's what I've been looking for.

"Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library." Looks really rather interesting, and potentially beautiful.

"The Collision Detection Kit is a package of classes for pixel-precise, shape-based collision detection for all display objects. It is written in Actionscript 3.0 and meant for Flash Player version 9 and higher. The kit comes with several features to control how collisions are detected, and provides data for the user of the kit so they can do something about the collision." Might be interesting, we'll see.

"I gave a presentation on Treetop last night at lrug - seemed to go down well. There aren’t many examples of treetop grammars I’ve seen, so it might be useful if you find the main site’s documentation a bit impeneterable." Roland drops some Treetop science, and it looks very useful. Good stuff!

"Protovis is a visualization toolkit for JavaScript using the canvas element. It takes a graphical approach to data visualization, composing custom views of data with simple graphical primitives like bars and dots."

"pc_user is a lightweight authentication library for CodeIgniter. It focuses on simplicity and security." Indeed it does.

Custodian is the Ruby gem for accessing the Guardian Open Platform Content API that James Darling, Kalv Sandhu, and I (although my contribution was minor) built. There's a Google Code link to it, but I'd imagine the github version is where the action will be.

"A Ruby library that wraps the Viapost SOAP API, providing an easy way of sending post (you know, real letter box post) from your applications."

"FeedTools is a simple Ruby library for handling rss, atom, and cdf parsing, generation, and translation as well as caching. It attempts to adhere to Postel’s law—i.e. a liberal parsing and conservative generation policy." Wasn't aware of this until now, remarkably.

"AlterEgo is a Ruby implementation of the State pattern as described by the Gang of Four. It differs from other Ruby state machine libraries in that it focuses on providing polymorphic behavior based on object state. In effect, it makes it easy to give an object different “personalities” depending on the state it is in." Oh, that could be really handy.

"Flare is an ActionScript library for creating visualizations that run in the Adobe Flash Player. From basic charts and graphs to complex interactive graphics, the toolkit supports data management, visual encoding, animation, and interaction techniques. Even better, flare features a modular design that lets developers create customized visualization techniques without having to reinvent the wheel." Oh, that could come in useful

"A whimsical riff on the bookmobile, Mr. Soriano’s Biblioburro is a small institution: one man and two donkeys. He created it out of the simple belief that the act of taking books to people who do not have them can somehow improve this impoverished region, and perhaps Colombia." Awesome.

"If you've ever needed to produce PDF documents before, in Ruby or another language, you probably know how much it can suck. Prawn takes the pain out of generating beautiful printable documents, while still remaining fast, tiny and nimble. It is also named after a majestic sea creature, and that has to count for something."

"Nothing quite prepares you for the culture shock of Jay Walker's library. You exit the austere parlor of his New England home and pass through a hallway into the bibliographic equivalent of a Disney ride." Incredible.

"Yahoo! Design Stencil Kit version 1.0 is available for OmniGraffle, Visio (XML), Adobe Illustrator (PDF and SVG), and Adobe Photoshop"

"Syncopation from Sonzea provides a hands-free solution to keep your iTunes® music collection synchronized across multiple computers running Mac OS X." And this is what might make a Squeezebox practical chez nous.

Thomas Jefferson's entire library - and his reviews of books in it - exists as an account on LibraryThing. I'm glad that things like this exist in the world, and that the Internet makes them possible.

New release of jQuery: as usual, it's a blend of rather impressive performance boosts and some neat new functionality.

"Drawing on inspiration from Plotr and PlotKit, software developer Ole Laursen wanted to bring the same plotting functionality to jQuery. So he built his own jQuery plugin and called it Flot." That looks rather nifty.

"WWW::Mechanize and Hpricot on Steroids". An interesting looking screenscraping library; I'm a big fan of both HPricot and Mechanize, so it'll be interesting to put this to use at some point.

Simple, effective Ruby library for creating AIM chatbots.

"Most introductions to jQuery focus on designers and inexperienced developers. I’m going to try to explain why jQuery should be of interest to experienced programmers as well." Excellent introduction to jQuery from Simon.

Gosu is a 2D game development library for the Ruby and C++ programming languages, available for Mac OS X, Windows and Linux.

jCodeViewer is a jQuery plugin which allows you to turn any div, textarea or pre tag into a simple Code viewer in an inobtrusive manner.

If in doubt, compress your own - the Prototype team aren't going to do it for you, after all.

Really lovely way of handling paginated searches in Rails - think I'm going to try this out on current project.

MonsterID is a method to generate a unique monster image based upon a certain identifier (IP address, email address, whatever). It can be used to automatically provide personal avatar images in blog comments or other community services.

"Amb is a library that allows you to choose from a number of possibilities." Offers up some lovely possibilities.

Someone beat me to the punch - takes a different tack to my acts_as_akismet, but definitely worth a look.

FasterCSV is exactly what it says - a faster CSV library for Ruby
