‘Tis the Season … To Write Better Code

The holidays are here and for web nerds that means only one thing — another wave of advent tutorials is hitting the web.

It doesn’t feel much like winter right now at the Webmonkey lair, but that’s okay because we mark the start of the holiday season by the launch of 24Ways, the grand poobah of advent calendars for web nerds. 24Ways has been an annual tradition since 2005, offering 24 articles packed with new tips and tricks showcasing some of the year’s best new ideas in web development.

This year’s 24Ways kicked off with a tutorial on HTML5 Video “Bumpers” by 24Ways founder Drew McLellan. Other articles thus far include how to start a project on the right foot, how to contribute code to the community and Geri Coady’s excellent article on Color Accessibility.

While 24Ways may be the biggest name in advent tutorials, it’s not lacking for competition these days. We also recommend the Performance Calendar, which tackles the often confusing world of website optimization. There’s also Digitpaint’s advent calendar which we enjoyed last year and has already published some nice articles this year, including this look at CSS filters.

If you’re missing another favorite, the PHP Advent Calendar, fear not, it has returned, but with a new name and domain: PHP Advent is now Web Advent. The name may have changed, but Web Advent offers similarly great content, like this article on Sharing What You Know by Heather Payne, the founder of Ladies Learning Code.

BBC Taps the Past to Showcase the Future of Web Audio

HTML5 offers developers new ways to display and work with both audio and video on the web. The HTML5 <video> element tends to get more attention, but the HTML5 audio element is equally revolutionary, perhaps even more so thanks to the work-in-progress Web Audio API (currently in the draft stages).

Developers at the BBC recently set out to push the limits of what you can do with HTML5 <audio> and the Web Audio API. The result is a new audio playground site that recreates the sounds of the BBC Radiophonic Workshop using the Web Audio API. Note that right now only WebKit browsers support the Web Audio API. (Firefox supports the older, deprecated, Audio Data API, but plans to ship support for Web Audio in 2013.)

The BBC’s Radiophonic Workshop project is one part cool demo, one part tutorial. It’s fun to play around with, sure, but another reason behind the experiment is to document how to use <audio> and the Web Audio API. The developers also wanted to put the API through some real-world use cases, to see if there are any limitations that could be addressed before the Web Audio API becomes an official standard.

Each of the four demos has a thorough code walk-through showing exactly how it works and which elements of the Web Audio API are being used. There are a couple of dependencies, namely JQuery and Backbone.js, but most of the code is working directly with the Web Audio API.

If you’ve ever wanted to explore the Web Audio API, these demos make a great introduction to how everything works. For more background on the project, see the BBC’s Research and Development blog.

So far the code doesn’t seem to be available through the BBC’s R&D GitHub account. You can always copy and paste from the demo site, but it would be nice if it was available for easy forking and experimentation.

Google Drive’s New ‘Site Publishing’ Takes on Amazon, Dropbox

Google has unveiled a new feature dubbed “site publishing” for the company’s Drive cloud hosting service. Drive’s new site publishing is somewhere between a full-featured static file hosting service like Amazon S3 and Dropbox’s public folders, which can make hosted files available on the web.

Google has set up a simple demo site served entirely from Google Drive to give you an idea of what’s possible with the site publishing feature. Essentially site publishing gives your public folders a URL on the web — anything you drop in that folder can then be referenced relative to the root URL. It’s unclear from the announcement how these new features fit with Google’s existing answer to Amazon S3, Google Cloud Storage.

The API behind site publishing works a lot like what you’ll find in Amazon’s S3 offering. If you use the Drive API’s files.insert method to upload a file to Drive, it will return a webViewLink attribute, something like That ugly, but functional URL becomes the base URL for your content. So, if you uploaded a folder named images, with a file named kittens.jpg, you could access it on the web at

There’s one drawback though, Drive’s site publishing doesn’t appear to support custom domains, which means it works fine for assets like images, CSS or JavaScript, but unless you don’t mind serving your site from some funky URLs, it’s probably not the best choice for hosting an entire site.

There are already numerous static file hosting solutions on the web including Dropbox and Amazon’s S3, as well as whole publishing systems that use Dropbox and S3 to host files, but for those who would prefer a Google-based solution, now you have it.

For more details on the new API see the Google Apps Developer Blog and be sure to read through the Drive SDK docs. If you need help, Google is answering questions over on Stack Overflow.

New Amazon Maps API Challenges Google

Amazon is once again jumping into the online mapping fray with a new Maps API for Android developers building apps for the Kindle Fire and Kindle Fire HD tablets. While it’s just for Android developers at the moment, several of Amazon’s other APIs have started small and grown into web-wide offerings.

Unfortunately, unlike like Amazon’s long since shuttered A9 map tools, it doesn’t appear to actually be using Amazon data. In fact, the new Maps API is really just an API wrapper around Nokia’s maps and geocoding interface, which also now powers the maps on

Like Apple’s iOS 6, Foursquare and other high-profile Google Maps defectors, the Amazon Maps API seems to exist primarily as an option for those who’d like to avoid the Google Maps API. Amazon’s announcement touts the API’s “simple migration path for developers who are already using the native Google Maps API on Android,” but neglects to mention any benefits developers might gain from dropping Google’s API.

In this early beta offering Amazon’s Maps API doesn’t have any features above and beyond Google’s API. The Amazon Maps API offers most of the same features you’ll find in the Google Maps API, including street maps, satellite images and custom overlays for landmarks and points of interest, but lacks street-view imagery, terrain maps and other features found in Google’s offering.

If you’d like to give the Amazon Maps API a try in your Android app, head on over to Amazon’s new Maps API site to request access.

Rails App Details Apple’s New ‘Passbook’ Web Service

Apple’s recent iPhone announcement contained one tidbit of interest for web developers — Passbook.

Passbook is a new app coming in iOS 6 that collects your boarding passes, movie tickets, retail coupons, loyalty cards, and more and stores them all in one place. Checking in for a flight? Just pull up Passbook and you’re done. Ditto for redeeming coupons, getting movie tickets and so on.

What makes Passbook interesting for web developers is that on the back end there’s a REST-style API for sending updates. The API allows developers to register web services which can then automatically update content on the “pass,” as Passbook entries are known. For example, you could update a coupon or add more credit to a pass based on a transaction on your website.

Passbook communication happens through Apple’s new PassKit web service. The PassKit API offers endpoints to get the latest version of a pass, control push notifications for a pass and query for passes registered for a device.

As with all things Apple, you’ll need a developer account to build anything, but if you’d like to get some idea of how

the web service end of Passbook works, check out Mattt Thompson’s passbook_rails_example. Thompson has put together a basic Rails app that shows how to work with Passbook, including how to register devices, get the latest version of a pass, get serial numbers for passes on a device and unregister a device.
