And That’s a Wrap!

Another year another Leetspeak; and it was great bringing this conference to life.

We had a really nice venue this year and great speakers with really insightful topics that left many of us inspired. The theme was “It’s Alive”, and in truth, that is exactly how it felt. The whole event was bustling with life — everything from the sessions to the conference floor. All the knowledge, the awesome Lego creations and the little museum seemed very appreciated; and I am really happy about that.

We all learnt a lot about bringing and keeping things alive and I hope you all enjoy your Estimote and use it to breath life into your environment.

I, myself, was totally beat when everything was packed and we, the crew, finally arrived at John Scott’s to decompress. In a sense I was not very alive. However it was great seeing so many people there having a great time talking and hanging out. I really enjoyed the energy in the room.

This year we closed the ticket sales at a staggering 425 tickets which makes this years Leetspeak the biggest so far. In the end we got 221 green, 24 yellow, and no red votes for the conference — which I appreciate a lot. I really hope we can do even better in the upcoming years!

On twitter we hit number one in Sweden in the morning and managed to hold on to that place for quite a while. We did this with a whooping nine hundred something tweets and that does not count re-tweets or the #1337gos hashtag.

All in all it was really nice having all of you there and it was great fun putting it all together. Thank you for being part of a wonderful community!

Soon we will be posting pictures and videos from the conference so stay tuned.

I am looking forward to doing it all over again!

See you all next year.

Open-source overload!

We certainly never made a secret of the fact that we <3 open-source at tretton37, both building and contributing. That is why we are REALLY EXCITED to see what an absolutely awesome turn out, from the open-source community, that we are having at this years Leetspeak! Some of the biggest projects in the .NET open-source community are going to be represented, by the people who created and actively contribute to them.

Why is this so awesome, you ask? Fortunately these people love their projects and open-source in general and are more than happy to strike up a conversation on either. So if you want to learn more about either of these projects, or have questions related to open-source as a whole, why not take the opportunity to chat with them?

We’ll see you there!

Why should you come to leetspeak?

I first came to Leetspeak in 2012. It was also first ever Leetspeak, but I didn’t know that at the time. To tell the truth, I didn’t know much about tretton37 or Sweden. I knew Martin Mazur, having met him two weeks earlier at DevDay. He impressed me as a person and sold me tretton37 as a great company, and it seemed to get even better when he added “and we also make our own conference in two weeks in Malmö” but he continued “unfortunately it’s already sold out”. This didn’t stop me. Let’s just say that I took “sold out” to be a state of mind.

It blew my mind. I was amazed that a couple of hundred of people were willing to sacrifice their Saturday to learn. I was even more amazed that people were sacrificing their Saturday to teach others for free. And we’re not talking just “any” people, but top tech speakers. Those two conferences in the autumn of 2012 changed my life and my approach to software development as a career. I realised how much is out there, and how much I still have to learn. It turned me into conference junkie, and since then I’ve attended or spoken at over 20 conferences. However, still to this day, these two remain my favourites.

Leetspeak is made by developers for other developers. It’s designed to be small and friendly – a real community feeling. We know that the biggest value of events like this is meeting new people and getting inspired by them. We understand that attendees want to learn new things, and that’s why we have hand picked 6 great speakers with interesting, inspirational and entertaining talks. We always host Leetspeak on a Saturday, which makes it possible for a larger audience to attend. And – the icing on the cake – we make it affordable for everyone. It’s almost more expensive not to come! Alongside all of this – and possibly most important factor – we keep the quality high.

So, in other words, Leetspeak is awesome. Lots of smart people just like you from all around Europe, some great talks and a beautiful venue. If you’ve attended before, you know what I’m talking about. If you haven’t, then this year is your chance. Treat yourself. I’m coming and you should too!

Don’t Worry; We Can Remind You!

Nobody likes SPAM or hotel-californa-mailing-lists that you forgot you ever signed up for and now can’t leave — even if you “check out”. Last year we where in Gothenburg and maybe not everyone is interested in getting mails from us about Stockholm. Also we promised we wouldn’t spam you — so we wont.

This is why we started a new mailing-list for Leetspeak 2015 instead of re-using last years list. If you are on the list you will get a friendly poke about important events such as:

  • Reminders before and when tickets are released.
  • Pre-conference happenings.
  • Other stuff we think you might be interested in.

And as always we promise we will play nice with your information and not shared it with others. If you are interested, sign up below!

Meet the Speakers

The speaker committee has been working really hard these last couple of weeks to finalize this year’s speaker lineup. There were many interesting speakers contacted and a couple even contacted the committee — even though we did not hold an open CFP.

When we launched the site we announced our first three speakers — Karoline Klever, Balázs Suhajda, and Scott Wlaschin.

Karoline is a passionate .NET developer that loves to continuously challenge herself both when it comes to software and sharing knowledge.

Balázs, even though he works with interface development by day, loves the blinky-lights and buttons by night. Not only that but he labels himself as an eco-conscious life-long-learner which I am sure will contribute to extremely interesting content.

Scott has over 20 years of experience in software development and a huge passion for F#. Not only has he created but he is also a very active and well-known speaker in the F# community.

So what are we adding today?

Well, we wanted some more hardware, more IoT more things that are alive! We are really excited to bring Clemens Vasters, David Fowler, Anders Søborg, and Lars Jeppesen into the mix.

Clemens focuses on the Internet of Things, Smart Products, and digitally enhanced infrastructures in our daily lives. He is probably most known for his role as a lead architect of the Azure IoT Services and Service Bus Messaging at Microsoft.

David, also from Microsoft, works on the ASP.NET team and is known for things such as Azure deployments (kudu), NuGet and SignalR.

Anders Søborg & Lars Jeppesen are the authors of Monobrick, a .NET firmware replacement for the Lego Mindstorm EV3 – they are both senior developers and work with C#, C++ and embedded systems in their day-to-day lives.

I want to thank Andreas, Emy, Justin, Madeleine and Michał for excellent work on wrangling this lineup. They have done a fantastic job in getting relevant, high quality speakers that will give us the advanced content that Leetspeak is all about.

I have seen the abstracts for the sessions and it’s going to be fantastic! I’m looking forward to sharing them with you shortly.

Until then — stay tuned! And if you would like to get information about abstracts and tickets from us via e-mail, sign-up below!

Meet the committee!

“Do you want to join the speaker’s committee for Leetspeak?”. Just the bare thought of it was frightening when I first heard the words. Leetspeak, which has been sold out in only a couple of hours previous years, needs the absolute best speakers to become the success that it actually is. Without any experience of being part of speaker’s committees I decided – “heck, of course I will rise to the challenge!”.

I had no idea what I was getting into.

So, what does the speaker’s committee really do? In contrary to some popular beliefs, we don’t meet up and have “fika” all the time. Instead, we gather about once a week and discuss which speakers we would like to invite to the conference and what kind of sessions we want. Pretty simple, huh? Well, since the committee consists of Andreas, Emy, Justin, Madeleine and Michał – five people with five different minds and varying interests, it’s a hard task to solve – but it also enables variation amongst speakers and topics. For example Michał is conference junkie and loves F#, Andreas and Justin have a soft spot for hardware hacking, while Emy and Madde are passionate about creating a more equal tech environment.

The first thing we did was to start brainstorming for people that we wanted to invite to the conference and to connect them to the subjects they were speaking about. We knew we had six slots to fill and that we needed a theme that could run as a silver thread through the conference. With that in mind, we chose six different subjects that we found interesting and thought that the community would like.

Thereafter the speculations regarding a possible theme began. Based upon our vision about sessions ideas started forming, one crazier than the other, until we realized the essence of what we were doing – we were bringing a conference to life. Life is something that surrounds us all the time – our code base is alive (and sometimes even has a life of its own…) as our teams are alive and – hopefully – evolving over time. But it’s not always simple to keep something alive, it takes both passion and commitment, which is also the feeling we want the audience to have when they leave Leetspeak.

After deciding that “It’s Alive” was a good theme (especially since that permits us to do something cool like having robots on stage) we begun to map our list of possible speakers to the topics of our choice. This was a pretty simple and straightforward process. But then the fun part began – contacting the speakers and asking if they were interested in speaking at Leetspeak!

I was actually overwhelmed by the positive response we got, because most of the speakers that had to decline did it because they were already fully booked, and asked us to return in coming years. From this we learnt that it’s better to start contacting speakers in good time, perhaps to even as early as a year in advance. This is definitely something we will take into consideration. Since we know that Leetspeak is always taking place in October, creating preliminary plans shouldn’t be too difficult.

The process of contacting speakers was probably the longest, and was carried out in batches until we had a long list of people to choose between, and also a solid list of abstracts for interesting talks. Choosing six people, when we had so many awesome and worthy candidates, was probably the most challenging task we had to face. In moments like that, I really wished that Leetspeak would be a multi-track conference so we could just invite them all.

When that process was over, we simply handed the rest over to our awesome service delivery, who handles everything that has to do with booking flight tickets and accommodations. Though it’s not really really over for us yet – we are still waiting to release the three final speakers as well as all abstracts. It’s a bit nervous but also super fun to hear the feedback we get from the community and to see all the excited people that are waiting as much as us for the 10th of October. Time can’t fly fast enough!


Interesting facts:

  • Number of people contacted: 45
  • Amount of fika had: 0…
  • Craziest theme idea: “Something, something, something… code.”

Leetspeak is Back!

It’s on again! Leetspeak is back for a fourth year and we are happy to launch our website! Not only are we back we; we are back in Stockholm – this years conference will be held at Berns on the 10th of October with the theme “It’s Alive!”.

We felt that the theme, not only, is quite fitting given current trends but also represents something we, as software people, have always been quite familiar with. The idea that many of the things we create tend to take on life – maybe not in the classical sense – but in one form or another.

We have worked hard to build a conference that is both informative and fun this year with 6 speakers from around the world bringing you advanced content that will leave you inspired and confused. Today we are proud and happy to announce Karoline Klever, Scott Wlaschin and Balázs Suhajda as our first three speakers.

Stay tuned for more speaker announcments, session abstracts, schedule, and other news coming your way shortly. If you would like us to notify you of updates don’t hesitate to signup for our mailing list below!

Have a great day!
