Talking about Servo in Hackference Birmingham 2016

I visited Birmingham for the very first time last week, to give a talk at Hackference. Apparently the organiser always swears that it will always be the last hackference, and it has been “the last one” for the last four editions. Teehehe!

I spoke about Servo. They didn’t record the talks but I did an screencast, so here’s it:

📽 Here are the slides, if you want to follow along (or maybe run the demos!). The demos come from the servo-experiments repository, if you want to try more demos than the ones I showed.

If you watched this talk at ColdFrontConf, this one has more clarifications added to it, so complicated aspects should be easier to follow now (specially the explanations about layout calculations, optimisations, parallelisation and work stealing algorithms).

People enjoyed the talk!

Someone even forked one the dogemania experiment to display other images:

And Martin got so intrigued about Servo, he even sent a PR!

I didn’t get to see much of the city, to be honest, but two things caught my attention:

a) it was quite empty even during ‘rush hours’
b) people were quite calm and chill

That’s perhaps why Jessica Rose is always saying that Birmingham is The Absolute Best place. I will have to find out some other time!

A very funny thing / activity / experiment happened in the slot before my talk. It was a reenactment of the BBC’s Just A Minute show, which I have never watched in my life. Essentially you have 4 participants and each one has a little device to “stop the show” when the active participant messes up. The active participant has to speak for a minute on a given topic, but they cannot hesitate or repeat words, so it starts getting challenging! This was organised and conducted by Andrew Faraday, who also helped run the Web Audio London meetup a while ago and is always an interesting nice person to talk to.

So this, this was hilarious beyond anything I expected. I guess because I didn’t expect any funny thing in particular, and also because I didn’t have any preconception of any of the participants being a “funny person” per se, so the whole comedy came from the situation and their reactions. It had some memorable moments, such as Terence Eden’s “unexploded item in bagging area” (in relation to the Samsung Galaxy Note 7 exploding fiasco, plus the very annoying voice that anyone who’s ever used a self-service checkout till in the UK will recognise 😏).

After so much laughing, I was super relaxed when the time for my talk came! Every conference should have Andrew doing this. It was excellent!

Other interesting talks and things:

  • Felienne Hermans’ on machine learning and bridge playing AIs built with DSLs built with F# – I basically don’t know much about any of these subjects, so I figured this could be an interesting challenge. You can watch this recording of this talk from another conference, if intrigued.
  • Martin Splitt’s aka geekonaut talk on WebGL – if you have the chance to watch it, it will be quite informative for people who want to get started in WebGL and learn about what it can do for you
  • I’m certainly not a Web Audio beginner, but I tend to watch those talks anyway as I am always curious to see how other people present on Web Audio. Hugh Rawlinson‘s presentation on Web Audio had a few interesting nuggets like Audiocrawl, which showcases the most interesting things in Web Audio. He also worked on meyda, which is a library to do feature detection using Web Audio.
  • Jonathan Kingsley gave one of the most depressing and hilarious talks I’ve seen in a long time. IoT is such a disaster, and the Dyn DDoS attack via IoT devices, just a couple hours after this talk, was so on point, it almost seemed deliberate.
  • Finally Remy declared his love for the web and encouraged everyone to get better and be better to others – and also stressed that you don’t need to use all the latest fashions in order to be a web developer. It’s good when renowned speakers like Remy admit to not to like frameworks, despite also seeing their strengths. A bit of balance never hurt anyone!

The conference had a very low key tone, let’s say that it was a bit “organise as you go”, but due to the small scale of the conference that wasn’t much of a problem. As I mentioned before, everything was pretty chill and everyone was very approachable and willing to help you sort things out. It’s not like a had a terrible problem, anyway: my biggest problem was that my badge had been temporarily lost, but no one told me off for not wearing a badge while inside the venue, and I eventually got it, heheh. So yeah, nice and friendly people, both attendees and organisers.

I also liked that everything was super close to the train station. So there was no need for additional transportation, and we could use the many food places in the station to have lunch, which was super convenient.

Oh and Jessica as MC was the best, I really enjoyed the introductions she prepared for each speaker, and the way she led the time between talks, and she was really funny, unless presenters that think they are funny (but aren’t).

If you have the chance, attend the next Hackference! It might the last one! 😝

Here are other conference write ups: from Dan Pope and from Flaki (who stayed for the hackathon during the week-end).

“Hands-On Web Audio” at London JS meetup

I gave my “Hands-On Web Audio” talk at the London JS meetup, held at the offices of Just Eat. It was broadcasted as a Hangout, and also recorded so you can replay or see if you couldn’t attend:

If you want to play along, the slides are live here and here is the source code as well. Disclaimer: depending on your computer, they might be a bit too much in both Firefox or Chrome. There seems to have been a regression and the intro sound is extremely stuttering in “slower” computers (slower as in “a MacBook Retina”).

It was a bit awkward because their big screen was actually six TVs and most of the content in my slides is centered vertically on the slide, which coincided with the middle of the frames, so it was quite unreadable. That is why you’ll hear a number of comments akin to “oh this is very inconvenient” from me, during the talk.

After I finished the talk itself, we had a round of questions, and I also showed how to debug web audio with the Web Audio editor in Firefox DevTools.

Feedback on the talk seems really positive and I’m happy people got interested in playing with the Web Audio API and making dubstep! YES!

Great talk! I left inspired to go play. I’d used some features of the audio API before but Sole’s enthusiasm and dubstep obsession triggered a string desire to get creative with it again.

Spectacular demo by Soledad. She really knows what she’s talking about

I’m really happy that people were happy and interested in the API 🙂

Side note, 1

A few people asked me about the slides: how are they made?! are they WebGL?! can they use the system to make their own slides?

Answer: they are WebGL, and they use three.js underneath. Right now the system is quite hardcoded, but I’m happy to announce that I’m working on refactoring the code so anyone can build their own 3D slide deck, using their own demo scenes. So I guess I am building a slide deck framework… 😬 #sendhelp

You can have a look at the project here, but don’t send me requests yet, kthx. An online demo is available as well. Right now it can only render basic H1-H4 and P nodes… in 3D! Not bad!

Side note, 2

I was really excited that I made it to the meetup (!), because I forgot my phone home that morning. I found out when I was in the office already, and I didn’t want to go back. So I printed the map and started cycling to the meetup place. Except I didn’t know very well the area, so I got lost twice. Not too bad though, I stopped and produced my paper map and let people look at me with weird looks (“she’s looking at a paper map!”). Anyway, I used:

a) my brain, instead of trusting everything to a GPS enabled device
b) those little maps in the street showing where you are

and I made it!

The way back was easier as I knew the area before. I tracked my route using my fitbit, and was really pleased to see that I had reached almost 30km/h on my humble Brompton.

It was coincidentally also Cycle To Work day yesterday, so I was doubly pleased that I cycled to work and also to meet up.

Should there be a Cycle To Meetup day too? I think so 😏

ColdFront 2016

I spoke at ColdFront in Copenhagen last week. I joked that I just accepted the invitation because I wanted to go back to Copenhagen, and it actually wasn’t far from the truth as it’s a lovely city and I had a great time when I went there for At The FrontEnd last May: going through the airport is easy, the trains and metros are spotless and easy to buy tickets for, the city is beautiful in its flat Nordic way (Stockholm and Oslo are quite hilly), lots of interesting design stuff to look at, people were super kind and nice to me at every single point, attendees were really polite and so on and so on. How would you not want to go back to a place like this?

So when Kenneth reached out to see if someone could talk about Servo and given that I was working on Servo this summer, it sounded like the Perfect Plan.

Fast forward a few months, and I was in Copenhagen again.

I unfortunately had to miss the first talks of the day as Perfectionist Sole was obsessing over her talk and her slides, but what I saw was really interesting. It was a very good exercise of curation.

Bruce Lawson delivered a very interesting talk loaded with facts about how to deliver the web for everyone—not just rich people on the Western world! Lots of technical insights about Opera Mini optimisations and infrastructure (this was fascinating), lots of research insights as to how do people with unreliable expensive networks use their phones and data plan, etc. Building Proper Web Apps (my new rebranding for PWA, haha) is the answer to these issues. So… learn your tools for a brighter, speedier and more reliable future!

Then there was the break in which we tested our laptops with the A/V system. It turned out that the system was having some fun and introducing random glitches and red jitter so things could occasionally look funny. I was happy with the aesthetics but “sadly” the technicians fixed it during lunch—while we were enjoying the tacos and rye bread sandwiches outside!

It was then the turn for Mathias Bynens who talked about ways in which your browser can be fingerprinted via timing attacks, and other terrible things that left all of us really scared. Good talk explaining complex topics quite clearly.

I talked about Servo and how it is solving many problems, one at a time. You can watch it here:

Glen Maddern talked about strategies to avoid ending with “😈 Demonic CSS 😈”. He suggested a number of design ideas and even ‘tricks’ that you can actually use in most browsers (like currentColor), without having to add CSS preprocessors to a project. I think a gist could be: Just because you can write complicated stuff doesn’t mean you should. He also has started a series of screencasts where he talks about similar front-end topics in his funny and approachable way, be sure to check it out: Front End Center.

Finally Estelle Weyl talked about the need to go back to basics—again, to know your tools—for front-end developers. She asked urged people to reconsider bringing in another JS framework into a project if whatever they wanted to accomplish could not be done in a simpler way with “vanilla” JavaScript, and showed a few examples of ways front end developers are reimplementing things that the browser already provides support for, due to ignorance.

At the end of the talks, the two main organisers Kenneth and Daniel went on stage to tell us a bit about the history of the conference, how they started it, the debt they accidentally incurred in last year and how unhappy their accountant was, the terror of not selling tickets, and how this would be the last conference as Kenneth now lives in Vancouver and it’s very hard to organise a conference when you live so far away.

At this point everything got very emotional but fortunately Daniel and Kenneth hugged and said thanks, before we all broke down and started to cry. Then we clapped to thank them, Kenneth and Daniel took a deep breath and asked us to reposition to take the JS family photo, and we were off to the closing party which was at a well stocked brewery like 40 metres away (I had an alcohol free drink following my self-pledge).

It was lovely to talk with all the people there… I mean—I didn’t talk to all of them, but to the ones I talked to! Plus the weather was quite nice and we could be outside instead of yelling at each other inside the loud brewery.

Sadly, there won’t be another Cold Front so if you want to relive this, check the talks when they are published in their website. Or watch the talks from previous years in their YouTube channel!

Thanks for the lovely conference!

How to write a talk

Hey Sole, you have spoken on a lot of places and go to a lot of conferences, so maybe you have some advice on how to write a talk?

Yes, indeed I do! In fact, this question comes up so often that I figured it would be super useful to share my method with more people, rather than just individually 🙂

Before we start, allow me to highlight that this is my method, and it might not suit you. Talks come in many formats and shapes depending on their content, the audience and many other factors. I usually talk about technical stuff, and this guide is about writing that type of talks.

Also, if you’re the TL;DR type, I made you a flow chart (using draw.io):

Nodevember 2015: my keynote, and a novel in four chapters

I keynoted at Nodevember 2015, last November in Nashville, Tennessee. There were some technical issues with the audio and video not being very much in sync I think, and that’s why the video has taken some time to be published. Thanks to the organisers for recording it! It has been made available just today 🙂

What you might not know is that I almost didn’t make it to the conference. And I also had written a sort of novel detailing what happened before, during, and a bit of after. So, without further ado, here it goes:
