MozFest 2014, day 2

As I was typing the final paragraphs of my previous post, hundreds of Flame devices were being handed to MozFest attendees that had got involved on sessions the day before.

When I arrived (late, because I felt like a lazy slug), there was a queue in the flashing station, which was, essentially, a table with a bunch of awesome Mozilla employees and volunteers from all over the world, working in shifts to make sure all those people with phones using Firefox OS 1.3 were upgraded to 2.1. I don’t have the exact numbers, but I believe the amount was close to 1000 phones. One thousand phones. BAM. Super amazing work, friends. **HATS OFF**

Berlin Web Audio Hack Day 2014

As with the Extensible Web Summit, we wrote some notes collaboratively. Here are the notes for the Web Audio Hackday!

We started the day with me being late because I took a series of badly timed bad decisions and that ended up in me taking the wrong untergrund lines. In short: I don’t know how to metro in Berlin in the mornings and I’m still so sorry.

I finally arrived to Soundcloud’s offices, and it was cool that Jan was still doing the presentations, so Tiffany gave me a giant glass of water and I almost drank it all while they finished. Then I set up my computer and proceeded to give my talk/workshop!

It was an improved and revised version of the beta-talk I gave at Mozilla London past past week:


Note to self: maybe remove red banners behind me if wearing a red shirt, so as not to blend with them

Invest in the future: build for the web!

I spoke at GOTO Amsterdam a few weeks ago. I was really thrilled to be back in the Netherlands after so many years! So thanks to Sergi Mansilla, who curated the HTML5 track, and the organisation in general for bringing me there!

The talk wasn’t recorded, but I made a screencast just in case you really want to listen to me. I am also posting the outline/notes I wrote, and they differ in places because I don’t read them during the talk (I don’t even have them handy) and I sometimes went a bit off topic, but that’s the beauty of improvisation!

Here are the slides, and the slides source code just in case you wanted it too.

On to the notes-expect some MASSIVE GIFs and amazingly clever photomanipulation! tee hee hee!

Inspecting the Web Audio Vocoder demo with Firefox’s new Web Audio inspector

I wanted to understand how the Web Audio Vocoder demo by Chris Wilson worked but I didn’t feel like reading the whole code upfront, so I decided to open it using the new Web Audio inspector that you can find in Firefox Nightly.

The Web Audio inspector will render a graph with all the nodes in the current Audio Context, so it’s ideal to get a feel for the vocoder’s internal structure.

And the structure is PRETTY COMPLEX, as you can see in this massive GIF:

Here’s the Vocoder code, just in case you want to read it too!

Full credits for the Audio Inspector go to Jordan Santell, also of Dancer.js fame! :-)
