“Invest in the future, build for the web!”, take 2, at OSOM

I am right now in Cluj-Napoca, in Romania, for, an small totally non profit volunteer-organised conference. I gave an updated, shorter revised version of the talk I gave at Amsterdam past June. As usual here are the slides and the source for the slides.

It is more or less the same, but better, and I also omitted some sections and spoke a bit about Firefox Developer Edition.

Also I was wearing this Fox-themed sweater which was imbuing me with special powers for sure:

fox sweater

(I found it at H & M past Saturday, there are more animals if foxes aren’t your thing).

There were some good discussions about open source per se, community building and growing. And no, talks were not recorded.

I feel a sort of strange emptiness now, as this has been my last talk for the year, but it won’t be long until other commitments fill that vacuum. Like MozLandia—by this time next week I’ll be travelling to, or already in, Portland, for our work week. And when I’m back I plan to gradually slide into a downward spiral into the idleness. At least until 2015.

Looking forward to meeting some mozillians I haven’t met yet, and also visiting Ground Kontrol again and exploring new coffee shops when we have a break in Portland, though :-)

Tools for the 21st century musician—super abridged dotJS edition

I attended dotJS yesterday where I gave a very short version of past past week’s talk at Full Frontal (18 minutes versus 40).

The conference happened in a theatre and we were asked not to use bright background so I changed my slides to be darker and classier.

It didn’t really go as smoothly as I expected (a kernel panic a bit before the start of the talk, and I got nervous and distracted so I got more nervous and…), but I guess I can’t always WIN! It was fun to speak in French if only one line, though: Je suis très contente d’être parmi vous!–thanks to Thomas for the assistance in coming up with the perfect presentation line, and Guillaume and Sasha for listening to me repeat it until it resembled passable French!

While the video is edited and released, here’s a sample in the form of slides, online and their source code in GitHub.

It was fun to use CSS filters to invert the images so they would not be a big white block on top of a dark background. Yay CSS filters!

.filter-invert {
    filter: invert(100%) brightness(2);

Also, using them in transitions between slides. I discovered that I could blur between slides. Cinematic effects! (sorta, as I cannot get vertical/horizontal blur). But:

.bespoke-active.emphatic-text {
  filter: none;
.bespoke-inactive.emphatic-text {
  filter: blur(10px);

I use my custom plugin presentation-fullscreen for getting real fullscreen in my slides. It’s on npm:

npm install presentation-fullscreen --save

then just


will add a new option to the contextual menu for making the whole body go fullscreen.

I shall write about this tip and how I use bespoke.js in general, and a couple thoughts and ideas I had during the conference soon. Topics including (so I don’t forget): why a mandatory lack of anonymity is not the solution to doxxing, and the ideal talk length.

Firefox OS Bug Squash party

Oh hey, here’s another belated post from Sole! But at least it didn’t take me a full whole year to write ^_^

We hosted the first ever Firefox OS Bug Squash Party at Mozilla London (also known as MozLDN) last week, thanks to the initiative of Francisco and Guillaume that mostly brainstormed it all with support from Valentin Schmitt.

Full Frontal 2014

I had the honour and privilege to speak at Full Frontal this year. I also had the chance to watch most of the talks, so here are some notes and thoughts on the ones I was able to watch (I was too late for the first ones, and I’m so sad, because I’ve heard they were so good!).

Tools for the 21st century musician

That is the title of the talk I gave yesterday at Full Frontal in Brighton. The video is still not out but here are the slides (and the source for the slides, with all the source for the examples).

If you were in my Web Audio workshop in Berlin, this talk followed the same style, except I refined some points and sadly forgot a couple. I also showed the Web Audio Editor in Firefox DevTools, which I didn’t in Berlin because Jordan was going to talk about it after me.

I had a little bit of a surprise at the end of the talk, when I “presented” for the first time a little project we’ve been working on for a while: OpenMusic. And I have “quoted” the presented word because the work has always been in GitHub in the open, so if you followed me in GitHub you might have seen all the repos popping up and wonder what the hell is Sole doing lately.

So, just in case you weren’t in the conference, OpenMusic aims to be a nice collection of interoperable/reusable Web Audio modules and components. This is an idea that Angelina sort of had when they saw my audio tags talk last year, and has been brewing in the back of our minds until a couple of months ago when the A-HA! moment finally happened.

And so I’ve been pulling apart components and pieces from my existing Web Audio-based code, because I realised I was doing the same thing over and over and I wanted to do new things but I didn’t want to do the same thing yet again. So, small npm based modules it is. And a bunch of them!

I’m a bit short on time lately (and I’m being very generous on this description), so some of the modules are a bit too rushed and a tad obscure, but they should work and have some minimal documentation already, and they’ll get better. Be kind while I deconstruct my hacks–or better yet, start deconstructing yours too! =)

Thanks to Remy for inviting me to this ultra cool conference… and accidentally triggering the A-HA moment!
