Do you believe in magic? You will after using The Levelator® to enhance your podcast. And you'll be amazed that it's free, now even for commercial use.

So what is The Levelator®? It's software that runs on Windows, OS X (universal binary), or Linux (Ubuntu) that adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example. It's not a compressor, normalizer or limiter although it contains all three. It's much more than those tools, and it's much simpler to use. The UI is dirt-simple: Drag-and-drop any WAV or AIFF file onto The Leveler's application window, and a few moments later you'll find a new version which just sounds better.

ou've reached this page, chances are good that you were asked to capture a Web Traffic log.  Usually, this action is performed to track down a bug in your web browser or a website.

You can use FiddlerCap to take a snapshot of your Web Traffic, and send that snapshot to a debugging buddy who can troubleshoot the bug. 

To get started, just follow the steps below.

Fiddler is a Web Debugging Proxy which logs all HTTP(S) traffic between your computer and the Internet. Fiddler allows you to inspect all HTTP(S) traffic, set breakpoints, and "fiddle" with incoming or outgoing data. Fiddler includes a powerful event-based scripting subsystem, and can be extended using any .NET language.

Walkable neighborhoods offer surprising benefits to the environment, our health, our finances, and our communities.

Election leaflets are one of the main weapons in the fight for votes in the UK.

They are targeted, effective and sometimes very bitter.

We need your help to photograph and map them so we can keep an eye on what the parties are up to, and try to keep them honest.

RDFa helps bloggers and website authors make their web pages smarter by adding computer-readable information to a site. Details about yourself, events, places, books, and music are just some of the "things" you can describe using RDFa. By adding RDFa to your website or blog, you help computers interact with your website in a way that is more helpful to people visiting your site. RDFa makes web browsers smarter by giving people more options when viewing a web page, such as adding you to their address book, adding an event to their calendar, getting directions to a place described by RDFa, or searching online bookstores for a book marked up using RDFa. There are many possibilities with RDFa and this community is dedicated to RDFa education, development, and advocacy.

This session just went through 20 of the most used APIs in Drupal and described quicly what they can be used for. The presenter has also posted blog posts about some of these APIs in the month leading up to DrupalCon.

As a Masters student at DERI Galway, I research Semantic Web technologies and their applications in Content Management Systems. I was involved in the RDF in Drupal 7 initiative, lead by Stéphane Corlosquet, and am currently working on RDF documentation and related contributed modules.

I am currently working on a Google Summer of Code project to make it easier to bring RDF data into your Drupal site and use it in meaningful ways.

I also have contributed screencasts that give an introduction to Drupal 7.

here were presentations from the BBC about their Wildlife Finder, which pulls a lot of content and data from sources like Wikipedia and the WWF, and from Tom Heath of Talis talking about we need to move towards building applications for the 'web of things' rather than for the current 'web of documents'. Lin Clark gave an overview of how the next version of the Drupal CMS comes with RDFa capabilities built in to it.

Openly Local is a new project to develop an open and unified way of accessing Local Government information.

So far we have opened up data for over 140 local authorities, and more are being added every week, with more information being opened up too.

With this widget, you can make beautiful interactive timelines like the one below. Try dragging it horizontally or using your mouse-wheel. Click on each event for more details.

Node's goal is to provide an easy way to build scalable network programs. In the "hello world" web server example above, many client connections can be handled concurrently. Node tells the operating system (through epoll, kqueue, /dev/poll, or select) that it should be notified when a new connection is made, and then it goes to sleep. If someone new connects, then it executes the callback. Each connection is only a small heap allocation.

This is in contrast to today's more common concurrency model where OS threads are employed. Thread-based networking is relatively inefficient and very difficult to use. See: this, this, and this. Node will show much better memory efficiency under high-loads than systems which allocate 2mb thread stacks for each connection. Furthermore, users of Node are free from worries of dead-locking the process—there are no locks.

The Walkable and Livable Communities Institute is a nonprofit center based in Port Townsend, Washington.  Our mission is to make cities and towns throughout the world walkable, bicycle and transit friendly, livable, sustainable, socially engaging and welcoming places by improving their built form. It is challenging to have good health when our environments do not support us.

Walkable communities are thriving, livable, sustainable places that give their residents safe transportation choices and improved quality of life. Walkable Communities, in partnership with the Walkable and Livable Communities Institute, Inc., (www.walklive.org) helps them get there.
