In particular, we wanted to highlight one person that has had a huge impact on the music hacking scene – someone who pushes the boundaries of technology, someone who shares their knowledge with the community, and someone who embodies creativity and passion for music and tech. This person deserves a place in the Music Hacker’s Hall of Fame.

In the world of music and tech there is one person who stands out. He is one of the grand masters of the music hacking community. His name is Paul Lamere.

You can find Paul at just about every Music Hack Day, and his hacks are always technically challenging, forward thinking and fun. Paul is also the Director of Developer Platform at the Echo Nest where he leads the way for hackers to create new applications around music.

Paul is one of the nicest, most generous people you’ll ever meet, and he’s been a huge inspiration to us and other hackers all over the world.

For his passion, for his hacks, and for his kind and generous nature, we award Paul with a music hacking trophy and a place in the Music Hacker’s Hall of Fame. Give it up, for Paul Lamere!

You can follow Paul on Twitter, and read his blog at Music Machinery.

Make sure to check his hacks. There are too many to list, so here’s a few to get started:
Midem Music Machine
Six Degrees of Black Sabbath
Paul Versus Billboard

Plus some great hacks Paul did with his daughter Jennie:
Bohemian Rhapsichord
Jennie’s Ultimate Road Trip

We’ll see more people inducted into the Music Hacker’s Hall of Fame soon. There are lots of people who have contributed hugely to the music hacking community. Who will be next?

One of the important design decisions I made when building RocketPants was related to versioning – I believe it’s important in practical terms to version an API (within reason) but I strongly disagree with using custom content types to do the versioning for most things.

But why?

My argument for this boils down to a couple of small, key factors:

1. Discoverability

This predominately applies to public facing APIs but I believe it’s still important for general APIs as well. Discoverability of an API in this specific case refers to the ability to use a browser just like any other API client. AKA, I should be able to take a URL, type it into my browser bar, and see the body of the response. With the help of a good browser plugin or two (e.g. JSONView in Chrome), I may even get a structured and highlighted view of the data.

Doing headers is typically an extra step in most command line clients / http libraries (albeit not a hard one) but in most browsers it’s either quite a task (e.g. requiring an extra plugin) or just not possible.

I believe Echonest is a fantastic example of this – their API docs include links to example requests that work as in your browser, making it super easy to get started and to play around with the data, despite being versioned.

2. The Difference In Changes

My second issue refers to changes in side effects – specifically, in non-GET requests. Whilst the Accept-based approach still works as expected with HTTP caching and the like (since they’re used for normal content negotiation), but when different controllers implement different versions of the API call (e.g. creating something in version two has a different result than version one), your API will not function as expected.

Hence, the Accept based approach works for just different representations of the data, but when you change the logic, it starts to cause trouble – using a different endpoint completely (as signified by a different path) means it’s functionally a different resource and hence you expect those actions to change.

An aside: v1 versus 1.

This is a small one – I consciously chose to use /1/ in the generated paths for RocketPants over /v1/ for a number of reasons after talking to other developers. These primarily were based on the fact that A) it’s easier to scan (although only marginally), and B_ .to_i in ruby (and similar number conversions) work as expected with no surprises – the v adds no extra information but potentially offers confusion.

Conclusion

Ultimately, I believe you should choose the solution that feels right to you. My personal experience consuming and building APIs has led me to prefer this approach (and to be honest, if it was an ideal world, you’d probably eschew versions in favour of backwards compatible APIs with a decent deprecation time period), but for most cases I believe it’s more pragmatic to use versioning in the URL than it is to use header / Accept based versioning for the reasons above.

This is a BIG DEAL people!

Hackers will have one-time access to a range of exclusive data, including:

• Hottest 100 metadata from 1989 to 2011, including Rdio track ids and Echonest metadata. Hackers can query artists and tracks, and also the Hottest 100 ranking for that year.
• The ability to peek into extensive information about the Triple J Unearthed competition – 80,000 tracks and 36,00 artists who’ve submitted entries to Triple J Unearthed.
• Information about each weekly feature album on Triple J.
• Data about what’s on the radio now and what has been recently played.

If you’re coming along to Music Hack Day Sydney and this is the sort of data you’d love to hack on, there’s even more motivation. With thanks to Triple J and Otis Eyewear, we have a prize especially for the best hack built on the api.

Go forth and hack!

Wanna soak up the geek vibe and get caffeinated with code wizards and design lords but don’t know the different between a repository and a suppository?

Fret not, Hack-ling! You can join the team as a Music Hack Day Sydney volunteer!

Many hands make light work and in exchange for your faithful service, we’ll feed, water and entertain you AND give you a dope tee shirt. Winning!

Woo!

There’s a shedload of interesting humans already signed up for Sydney, and they are coming from near and far to share the experience.

One such human is Syd Lawrence; he’s making the epic trek from London just to join us for the first Aussie MHD weekender. He’s a freelance developer, part-time University lecturer and we hear Syd’s fans like to speculate as to whether or not he actually sleeps, because a new hack seems to appear on his blog every few minutes.

Syd has hacked the sh! out of the last few London hack days and if you don’t keep your eyes on the prize, his wizardry might sweep the MHD Sydney prize pool. Start hatching your hack plans people – you’ve been warned! ☺

What is a Music Hack Day?
So, are you into tech? Are you also into music? Well let’s make something interesting to do with music and tech!

I’ve been to heaps hack days and, in my experience, this is generally how it goes down…

A whole bunch of developers, designers, tinkerers get together in a room seeing what they can come up with if they really push the boundaries. All of them work on fun and interesting projects right throughout the night.

Some people will be working on projects all night long, others will decide to wimp out and go back to a bed, but bear this in mind; those 8 hours you are asleep? Yeah, someone just finished another hack in that time.

Sponsors come along, provide you with some APIs to use and some assistance throughout the weekend. There’s food and drink to make sure you are watered and fed. And there are even prizes for the best hacks!

Why you should attend
Are you in a full time job? Wish you had more time to play? Yes, you! You should definitely attend.

When was the last time you tinkered with something new?

Have you tinkered with a Kinect yet? How about the SoundCloud API? Or perhaps you wanna create a custom Rdio player? Right then, well now is your chance!

Hack days are the perfect opportunity. You get to tinker with new technologies and you are surrounded by many brilliant minds working on awesome things. Everyone is there to help.

Or perhaps you just want to check out the Red Bull HQ ;)

Oh, and you basically get free food and drink for a full weekend!

What kind of stuff gets made at Music Hack Days?
Many different things have been made over the past few years at Music Hack Days.

From Kinect hacks, Arduino based hardware hacks, through to high-level web apps, or mobile interactive installations.

Funny hacks, useful hacks, hackety hacks. You name it, let’s make it!

My personal top 5 hacks
CTRL – Interactive Music Installation
Tourrent Plans – Better concert tour planning with science!
HearMyFace – A face expression based midi controller that injects true expressiveness into your music.
Midem Music Machine – Web based 3D animated audio visualisation.
Drinkify – Never listen to music alone again!

So, if all of that didn’t get you excited, maybe this video featuring Syd and fellow pommy hacker Paul King, will. It was shot by Pauline de Zeeuw at Music Hack Day London, December last year.

And if you haven’t registered yet, get your rear into gear and sign up here! (We promise we won’t let Syd win ALL the prizes!)

See you soon.

Contemporary artist, habitual tinkerer, electronic music lover and maker; David Spencer will join the Music Hack Day touring party from sunny Western Australia to create live art hacks at Red Bull Australia HQ.

You should Google him – he’s a cool guy and people go nuts for his paintings.

David Spencer "For the love i know"

David Spencer "The Twittering machine" (diptych)

David Spencer "Wool stories" (Fremantle street art)

Dave will be on deck to collaborate on projects and create sculptural pieces for the MHD Winners’ Trophies out of repurposed objects, hardware and pretty much anything you leave lying around.

We’re not sure what exactly is going to happen. We’re just going to keep throwing more awesome in the Music Hack Day pot, give it a shake and see what falls out.

See you there!

Do you have one of the Discovr apps and want to find another? We have you covered:

Double tap a node and, you guessed it, find our more about one of the Discovr apps.

We hope you like it as much as we do. We expect the app to be submitted and approved by at least the year 2052.

There are a lot of great Twitter client apps available, but there aren’t a lot of great ways to find interesting people on Twitter. Our previous apps (Music, Apps & Movies) have all recommended similar things, this time we are using recent conversations on Twitter to help you find interesting people.

Just like with the other Discovr apps, it’s an interactive connected map. Tap a circle on the map to see connected people or double tap to see their details. Tap and hold on any person to see a quick profile, where you can read their bio, follow or add them to a list:

Selecting ‘view profile’ or double tapping on a person will show you all their details (including their tweets), all of their recent connections, who they are following and their favourite tweets.

You might start following a lot of new people, so Twitter lists can help you with that and we’ve made them a large part of the app. You can add people that you’ve discovered to new or existing lists straight from the map page. On the bottom of the screen, you can also see some of our favourite Twitter Lists, your own lists, plus other people’s lists that you have been included in.

Here is a video of the features:

Discovr People is available for iPad, iPhone and iPod Touch running iOS5+. You’ll need at least one active Twitter account registered (in your Settings app).

If you’re anything like us, you spent much of the past weekend holed up with your new retina iPad, lovingly installing, updating and generally marveling at how good everything looks on the new screen.

Here’s what’s new in the Discovr updates -

Discovr Music 2.3

• Full support for the new retina iPad display
• View the Top Songs for each artist
• Improved song previews for international users

Discovr Movies 1.2

• Full support for the new retina iPad display
• Improved search functionality
• Performance updates

Discovr Apps 2.1

• Full support for the new retina iPad display
• Improved search page
• Improved app data

We actually camped out overnight at the Apple Store in Perth for the new iPad release, curious to meet and hang out with other eager Apple fans that hit the pavement in sometimes pretty unfavourable conditions.
Here’s some snaps from our visual diary…

Ben, Dave and Kristy all settled in out front of the Apple Store Perth. Only 13 hours to go! Coffee anyone?

For Discovr team member Ben, NOT camping out simply wasn’t an option, so Dave and I packed up our beanbags and joined him for the party. We happened to meet some really cool new friends along the way, each with their own interesting motivations for sleeping rough on Apple’s doorstep. (Shoutouts to our new friends and queue allies Trent, John, Kye and Kara!)

The most common response when quizzed about camping out – “Why not? Its fun!” Everyone had their own reason for loving the product, but getting their hands on the goods seemed to come secondary – people were there to meet other fans and share the love and experience. It was awesome to see such a strong focus on the community experience between fans.

The line is growing quietly but steadily, the front of the queue is snoozing and the new iPad makes its first appearance in the window

Ben's a happy camper - the Apple staff appear in the early hours of Friday morning and give him, and other queue dwellers, a ticket confirming his iPad of choice is reserved. Winning!

The main event! As the media throng gathers, the Apple Staff chant, cheer and greet #1 ticket-holder Trent before embarking upon a victory lap of the block. The Apple Store is open and ready for business!

Trent & Ben bask in the afterglow (or the glow of their new retina screens!) and media attention.
