Our own Michał is going to speak at DevConf. And we have tickets for those of you who want to join him.

How do we usually facilitate a design sprint with our clients? Find out from our brief day-to-day report on our latest one we had with one of our customers.

A seminar organized by The Confederation of Swedish Enterprise in which we discussed effective language training for enabling immigrants to enter the job market.

During October, 1273 people gathered together all over the world to run for a cause. Together we raised awareness for girls and women all over the globe.

From October 1-31 we will run as much as we can to benefit a charity of our choice. For each 1337 meters we run, tretton37 will donate 50 SEK to the organization Girls in Tech.

As a side project at tretton37, a few of us ninjas have been working on a project we call LeetHack. It’s a system for competition, a chance for learning and a social event for nerds.

It is a hard thing to present things in a good way at meetings. When things are hard people often fall back on default. The default way of presentation is often Power Point by Microsoft. The culture in many companies sometimes is like: If you have a digital presentation then you are prepared for the meeting, otherwise not. This is not the modern way of meetings. This will hopefully give you some ideas how to make something differently: To be a presentation-ninja

Over the years we have been involved in many different Open Source initiatives, and always with our own passion for software craftsmanship at the core.

tretton37 will be hosting CoderDojo for girls between 7-17 years to get started with programming.

Last night, tretton37 was awarded the Most Diverse Company of the Year and we could not be prouder!

For all of you eagerly awaiting the upcoming devnull developer game in February, we’re arranging a series of weekend algorithmic challenges!

Escape from devnull is a science-fiction or fantasy adventure that you experience by coding it. Solve the problems - claim the prizes.

At tretton37, we believe in challenging the norm to progress. Now it’s time for us to challenge it once again.

Part 1 in the series about hardware programming. Introduction to circuits and electricity

It all started off with some spare time and an idea, so a little pet project was started to construct a magic mirror.

Escape from devnull is a science-fiction or fantasy adventure that you experience by coding it. It is also one of the greatest and most fun development tournaments that one can attend.

At tretton37 we have always used and developed open source software, it is just one of the ways we create value by sharing knowledge. During the last few years we have used Nancy for customers and pet projects, and during the years Nancy has grown to be a fantastic lightweight framework.

For us tretton37 knowledge and knowledge sharing has always been top priority. Our business model hinges on sharing knowledge, not only with our clients but also with the community and each other. This makes experimenting with different ways of learning key to our success.

The burning question came from one of the youngest members in the audience. As I gathered my thoughts, I noticed how the rest of the group was looking at me with the eagerness and impatience typical of someone whose thirst for knowledge is inversely proportional to their age. I felt the energy in the air. And so I began to give my answer.

Open source and the open source community are, and always will be, an important part of our company culture. It was not too long ago that we spent a full day contributing to various open source projects, as a small way for us to show our appreciation for the projects and all the hard work that goes into them.

I started at tretton37 just about a year ago. My first couple of weeks at tretton37 involved a lot of mug posting to the far corners of the globe. I couldn’t quite understand why requests were coming in from all over the world for a mug that had something about France being bacon on it. I just didn’t get it. So, I bought in about 900km of bubblewrap, thought “computer nerds are a funny bunch” and posted them off. Job done.

På lördag arrangerar tretton 37 sin systemutvecklarkonferens för tredje gången. Bolaget har vuxit till nittio anställda sedan starten 2010. Inom tre år vill man vara 150 medarbetare och etablerade utomlands.

ColdFront is a brand new, single-day front end conference taking place in Copenhagen on the 4th of September 2014. It’s kicking off in style with a pretty impressive speaker line-up, which can be found here.

Previously I’ve discussed the challenges of organising our Knowabunga days due to the wide range of different and exciting interests we have here at tretton37. When planning companywide activities we have to cater to all of these interests or we run the risk of not getting a return on the investment. We are convinced that learning goes hand in hand with the individual’s aspirations, and therefore interest is an important factor. I like to think that we have succeeded with that so far, but we can always strive to make it even better.

Yes, it’s time for another full-blown action-packed day of Knowledge! We’ll be enhancing our competence, and sharing our knowledge with one another – it’s the event we call Knowabunga! It’s also the final Knowabunga before we all head off to enjoy our well-deserved vacations :-)

We're happy to welcome you all to ‘Agilistas vs. Cowboys’ by Martin Mazur! The evening will kick-off at 17:30 with something nice to eat before Martin begins his session at 18:15. Afterwards we'll open the doors to our comfy office and you'll have the opportunity to grab yourself something to drink and carry on the discussion!

Our first knowledge day was code-named "Knowabunga Day". It is a direct reference to our favourite childhood cartoon; Teenage Mutant Ninja Turtles. One of the characters - Michelangelo - used to yell "Cowabunga!", a nonsensical word but with a lot of heart behind it.

Come join us for a night of board-gaming fun. Grab your Cloak of Obscurity, plot your railway line, and meet us in our Lund office from 18:00 for food, drinks, and a bunch of games!

Come and join us at our tretton37 office in Stockholm for an old-school movie night! We'll open up our doors at 17:00 and start the movie around 18:30, so feel free to drop in whenever you feel like during that time.

A while back I wrote about our knowledge sharing day and how we would spend that time on contributing to OSS projects. We are just around the corner for the second edition of this day which is now, after an evening of beer tasting, simply known as Knowabunga day. Yes, it's a word play on cowabunga, popularized to us swedes by the fictional team of four teenage anthropomorphic turtles, and the word knowledge. It's perhaps a bit on the corny side but it seems to have stuck so let's roll with it.

Maybe I am getting too old for travelling getting jet lagged or maybe it is just the fact that I had a surgery 2 weeks before going to the SPC that I was totally exhausted most of the time being there. I went to bed early every evening and got up early because I could not sleep any longer. So this is how it feels like to be an old man. Too tired to stay up at night and too alert to sleep in the early morning. So much for Las Vegas night life. He .. I blame it on the surgery and not the fact that I not so long ago turned 40. But the reason I went to this event was not to rumble in the jungle in the first place.

In 2012 I moved from Australia to Sweden to join the tretton37 family. This is my story, but it could also be yours. Well except for the “2012” part – that ship has sailed.

Leetspeak is a conference born out of the desire to bring inspiring, hardcore technical content to those who need to know. It's an alternative to all those big expensive conferences out there that are held on weekdays. It aims to be both affordable and accessible as it’s always held on a Saturday. We wanted to make it that anyone who has the drive to learn should be able to attend, not just those lucky few that can get sponsored by their companies and get time off work.

On Friday 31st January 2014 we started out with a fairly low level of expectation. It was "low" as in "we'd be happy if we get a pull request together" and there was also a whole stack of legal agreements that needed our attention. Some of the projects required that CLA's (Contributor License Agreement) were signed for a large variety of "you can't sue us" reasons. Expectations were also low due to the need for wading through large code bases and attempting to configure weirdly build set-ups, etc., things that may well occur when working on Open Source Software (OSS).

As developers and as companies we benefit tremendously from what is done within open source projects. We, and every one else profiting from this really owe it to the community to provide something in return - Quid pro quo.

Igår delades den årliga utmärkelsen EY Entrepreneur Of The Year ut på en galakväll på Slagthuset i Malmö. Deniz Yildirim, VD på tretton37, blev utnämnd till Årets manliga stjärnskott.

We created Leetspeak as a reaction to all the big expensive conferences out there. There’s nothing wrong with them content wise, but we felt that they excluded a lot of passionate developers that couldn’t afford or get time off work to attend. So we challenged the notion that a quality conference had to be expensive and scheduled on Monday - Friday. We created Leetspeak, affordable, on a weekend and with quality sessions/speakers that we at tretton37 would like to see.

It all started with a piece of paper with my name on it. You might think that I mean the ticket, but then you are not quite right. It was a place on the waiting list, meaning that I might get a ticket to Build. Nerves built up and I was of course hoping for that ticket every day. Fortunately, as you may have already figured out, that place on the waiting list turned into a genuine ticket, and who was happier than me? :-)

We love Knowledge Sharing! However, going to conferences like Leetspeak isn’t part of our daily work. Code crunches and weekend hackathons are nice activities but they just aren't feasible for everyone.

I find that people are preoccupied with history. Always looking back and referencing the past to make decisions about the future. One important fact to remember is that it is just that – history. What I mean by this is that the events we are reflecting on occurred in a context which is very different from our current situation. The processes we wrote, the work we did, the technology we used has eventually become stale. Everything has a shelf life simply because time moves forward and the context changes.

Under helgen den 16-17 februari kommer tretton37 att hålla ett välgörenhets-event för Team Rynkeby. Totalt 16 utvecklare, designers och testare kommer att samlas på tretton37s kontor i Stockholm och Lund. Där kommer man tillsammans att utveckla en webbapplikation för att underlätta Team Rynkebys välgörenhetsarbete. Team Rynkeby är ett nordiskt välgörenhetsprojekt som syftar till att samla in pengar till Barncancerfonden i Sverige, Sylva i Finland och Børnecancerfonden i Danmark.

Last week I had the opportunity to attend the SharePoint conference in Las Vegas. There were 10 000 attendees and around 4 000 exhibitors and speakers. Lots of people!

You are very welcome to our very first Mingle & Jingle event in Stockholm! The evening will be filled with great company, glögg and lussekatter. To top it all off - we're hosting the event in our brand new office.

You are very welcome to join us for an evening filled with gingerbread cookies, lussekatter, glögg and great company.

Malmö and Stockholm is participating in the Global Day of Coderetreat 2012!

This September, we had the fortune of partaking in Sweden Windows Azure user Group's Cloud Burst 2012 event. The event, hosted at Microsoft's facilities in Stockholm, brought attendees from all over Sweden as well as people from abroad, including our neighbour country Finland and even from Indonesia! And thanks to Streamshed, the event was not limited to the available seats in Microsoft's conference facilities, but was also live-streamed ... and recorded.

Last week, three of us from tretton37 in Lund had the opportunity to, along with two guys from a telecom company in Copenhagen, attend Dan North’s two-day masterclass, Faster Software Delivery. The class was held at Foo Café in Malmö which is an independent meeting place for people within the IT industry in the Malmö/Lund area in the south of Sweden. Foo Café is located in Media Evolution City, which is a nice place for this kind of event. In addition to that, the coffee and food served were great. (On a side note, it was really interesting to see six software guys trying to set up the AV in a meeting room)

We at tretton37 love to code and now, for the first time, it's time to bring that love to Stockholm. We would like to invite all of you developers in Stockholm to a robot battle to celebrate that Winter is coming.

It was just a matter of time. We have done it internally, and on a smaller scale in the past, and now we at tretton37 are elated to unveil Leetspeak, our first ever, full day conference, open to the public!

As the European football championship draws ever closer, we at tretton37 thought that we should warm up with an epic cloudball event! Cloudball is a fantastic game developed by Giraff in cooperation with Microsoft.

We at tretton37 never do anything half arsed. We’re into SharePoint and we mean it. We are ninjas, even on SharePoint!

Have you ever been in a software project where the IT staff that would run the system in production, was accounted for right from the start? My guess is not very often. In fact, it’s far too rare to see functionality being built into software systems specifically to make the job of the IT administrator easier. It's a pity, because pulling that off doesn't require as much time and effort as you might think with tools like PowerShell.

I'm sure you're familiar with this situation, and if not, you're either lucky or new: Starting a new assignment and taking over someone’s code, code that is in some sort of state of decay or disarray. Bonus points if the original author isn't even around anymore to answer any questions you have. Extra bonus points if there's no source control.

You know how your mother told you to never talk to strangers? Well, she was wrong. Not talking to strangers means never leaving your comfort zone, never exploring anything new and never learning anything beyond that what is familiar - .NET.

We would like to welcome you to an evening in the spirit of the holidays, with glögg, gingerbread cookies and socializing. There will even be a chance for you to try out flying the LeetZeppelin!

During Øredev this year we decided to have a zeppelin in our booth, and to make it more fun we decided that it should be remote controlled! After a few iterations (hardware projects can be done agile too) we ended up with the following thing - an Arduino powered zeppelin that communicates with a computer using XBee and is controlled with a Wiimote connected to the same computer. The leetZeppelin was built by Fredrik Leijon (@fleijon) and Marcus Olsson (@macke). We think that all the gazing at the sky and half opened mouths proves that it was a huge success!

As soon as we saw that Roy Osherove, the author of The Art of Unit Testing, was looking for companies to help him host TDD courses in Sweden we immediately responded. We didn’t want to miss out on such an opportunity - to have Roy Osherove come to our office in Lund and teach TDD!

Det Lundabaserade kunskapsbolaget tretton37, som hjälper sina kunder att nå sina mål med hjälp av olika typer av mjukvarulösningar främst på .NET-plattformen, arrangerar för första gången konferensen Leetspeak.

Recently I was struggling with how to share and re-use code between my current client projects. An easy copy-paste of the code wasn’t an option, off course, since I don’t want any duplicated code. I could probably create a separate solution with the code I want shared and branch that code from our source control to the projects that need the code. As soon as I thought of this option I saw problems with people forgetting to merge back any changes in the shared code.

There comes a time in the life of an IT department when you want to migrate your projects from one TFS instance to another, e.g. from a 2008 to a 2010 installation, and you'd like to keep your version control history. To help us, Microsoft gave us TFS Integration Tools (there is an unofficial version at CodePlex too). It comes with documentation, but it's very theoretical and not very hands-on or, frankly, useful.

How often do we as developers get a chance to practice and really hone our craft without focusing mainly on the end-result? Wouldn’t it be great to try? We thought so! That’s why, in the spirit of Corey Haines, we’d like to invite you to a Code Retreat for a full day at our office in Lund.

tretton37 har tecknat ramavtal med Sembo avseende leverans av expertkompetens inom systemutveckling med Microsoft .NET. Under 2011 väntas affären omsätta närmare 10 MSEK och samarbetet avses därefter fortsätta.

Our awesome company tretton37 has grown from only two developers to 23 within only 13 months. Yet, we still want to grow and some surely wonder why… Here is a quick insight to my thoughts.

A while back ago I had the opportunity to take part in the development of a SharePoint Web Part that should display a plain list of open orders in a SPGridView. My previous experience of SharePoint hadn't exactly been a fairytale and nicknames like SharePain and PainPoint were frequently used in our team. These nicknames are still used from time to time but experience has shown me that by using test-driven development when developing a SharePoint Web Part the implementation can be made rather friction free. But to be honest the deployment process is not my friend and weird things keep surprising me.

A couple of weeks ago Dan North published the article "Programming is not a craft", discussing some potential risks with the Software Craftsmanship movement. This stirred quite a discussion between software professionals all over the globe. Many have strong arguments for each side, of course Bob Martin chimed in but also Martin Fowler. Marcin Floryan has a write-up collecting several links to different resources putting forth arguments for both sides.

The small Microsoft specialist tretton37 was founded by two consultants from one of the big listed consultancy companies. Contrary to many other competitors in the same region, tretton37 has made a strategic choice not to pursuit clients within the telecom sector.

We at tretton37 like to hang out and have fun while stilling our hunger for new knowledge. So we decided to do something fun and useful one evening every week.

Being a knowledge company sharing what we know and constantly learning new things is central to the work we do. What better way to share our ideas and thoughts, both as individuals and as a team, than through a shiny new blog?

We want to invite everyone to an open evening of holiday socializing. Even if the Internet is great we would like to meet up in person, chat and wish each other a fantastic holiday season. Please feel free to drop by our office for some drinks and snacks.

We want to welcome everyone to a full evening of building and fighting virtual robots. Let's all come together eat some pizza, drink some beer, program virtual robots and watch them blow each other to bits.

We are happy to announce that the nice folks from Blue Pebble are joining the tretton37 family.

We at tretton37 want to take some time to wish everyone a 1337 summer. During the last 7 months we've managed to build a really awesome business and we owe a big deal of it to YOU!
