As I wrote before the conference I was glad to see some good speakers on the Microsoft track. So of course I prioritized a couple of these sessions, and went to Mads Torgersens C# talk and to Mads Kristensen talking about tooling in ASP.NET. Well technically Thorgersens talk was on the architecture track, but you get the point.
The new world after Roslyn
The C# talk went a bit more into writing analyzers and codefixes than what I had seen before, so that was quite interesting and one of the very concretely usefull takeaways. The idea is that writing an analyzer is just like working with any object model. No more magic, so writing extentions is becomming something any developer can do and no longer reserved for the minority with too much time on their hands. Torgersen also demoed some of the new language features that I blogged about earlier, but on top of that let slide that primary constructors probably won't make it into the language for the final release in the comming version. The reason is that they want to do more and look at providing recordtypes as well as pattern matching - and want to make sure that they get it right. These are two great features that I miss from F# on a daily basis, so I was glad to hear this. I also aired the idea of make shorthands for stuff like factory methods, which could also reduce some of the boilerplate code that I see a lot. More...

At other conferences I have attended the last year or so, distribution and concurrency have been hot topics, coupled with functional programming and immutability which leands itself well to these kinds of problems. Todays program has certainly been no exception - at least for the talks I ended up picking.
The right Elixir for concurrent fault tolerant systems
In the afternoon I ended up sticking with the bleeding edge track, which has been really interesting. First off was a talk on Idioms of distributed applications with Elixir by Jose Valim, who wrote the language. In his talk Jose went over the idioms of Erlang, which is what Elixir is built on top of. He did a good job at presenting why light weight processes that are allowed to fail fast and recreated by supervisors makes it possible to build fault tolerant distributed systems that are easier to understand and run faster than other paradigmes often based on handeling exceptions via try catch blocks.

So first day of GOTO in Copenhagen has kicked off, with a somewhat provocative talk entitled "Does the browser have a future?" by Tim Bray - the farther of XML. His initial point was that the browser being declared dead hardly is a new thing since this also happened on the frontpage of Wired magazine in both 1997 and 2010.
A backend detour
Tim went on a detour to cover how this is the golden era of backend development, where life is good because you have few interfaces and testing is easy because it is machines talking to machines. He went over how Erlang, Clojure and Scala are popular but probably not the answer, where he was more optimistic about Go. This should hardly be a surprise, because he has been working at google for a number of years until quite recently. He did however make some good points about having a simple way to work with asyncronicity in a simple language. In the same way he made a short argument that it is also the golden era of persistence, with big companies using NoSQL solutions like Cassandra that enables them to build huge systems that scale with relative ease.

Sorry, but I can't help myself when a pun like this comes up. A couple of weeks ago Microsoft released previews of two new databases on Azure, called Azure Search and Azure DocumentDB. These two services make the storage story on Azure much more complete, for the needs of many a software developer. At least from my experience, they close a significant gap, where I have often gone "outside Azure", for something that would seem obvious for them to offer.
I have mostly been looking at DocumentDB, because it is more general purpose and because it is completely new - where Azure Search is built on top of Elastic Search. Having played a bit with the preview I am pretty excited to see how DocumentDB will progress. Certainly more than Ayende, who was quick to jump on the bashwagon - but of course he would hardly be doing his work if he didn't. As I wrote on twitter, I am excited about the idea, although I also feel that it has quite a bit of way to go before I would use it for production software.
As it turnes out, that tweet was read by the team building DocumentDB, so shortly after I was contacted and have been writing to them about my two cents on the subject. Suffice to say, that I like their openness and most of the answers that I am getting about where they are going. I was especially happy to hear that the preview version is limited with reguard to request sizes, and that performance is a key area of focus, so they will be looking at the feedback that they get on this.
From this experience I encourage everyone to give the team feedback. It can become a very good database, but as with a lot of projects, they need feedback.

Its a good thing I wrote my last blogpost when I did – otherwise I would not have had the chance to complain about the missing Microsoft track :) Shortly after I published my post, the conference announced just that track, and that Mads Kristensen is doing one of the talks on web tooling for ASP.NET. As a web-guy, that is really nice to hear, because Mads tends to have a bunch of good ideas to share, and he always gives a good talk. More...

A client of mine requested an integration with OpenWeatherMap, so like so many times before it was a chance to think about how to make such an integration robust and performant. Its as common a task as they come, but also something that tends to end up feeling more complex than I would like. Having heard a lot of good things and played a bit with Redis I felt that it would be a good choice for providing super fast caching, while also allowing for more than basic key/value storage.
Getting off the ground
The project is already running on Azure, so it was an obvious choice to give Azures new Redis based caching service a go. As of now the service is still in preview, but the the level of caching I need I feel quite comfortable with it. Getting started was as easy as most things on Azure - click add, fill in a name and press go. As every day as this has become, I am still blown away by how easy and fast it is every time I need to provision a new VM or service – and a Redis cache is no different.
On the downside I am not quite convinced by the new Azure portal, because to me the UX feels more shiny than useful. As of this writing the caching service is only available through the portal, but inspite of my reservations it was easy to get going, and it provides a nice overview of requests, storage space used as well as cache hits and misses.

As you may have noticed I have been blogging from the GOTO Conference in Aarhus the last couple of years. It has been a lot of fun and I really enjoy spending a few days absorbing as much as I can while trying to convey the messages through this blog. So even though I have moved across the country and closer to Copenhagen I was considering going back the GOTO in Aarhus this year. As it turnes out, this year there will also be a full-scale GOTO conference in Copenhagen!
It is nice to see that my move has coincided with the conference also taking place in Copenhagen, and it will be a great chance to meet more developers in this end of the country. I have been fortunate enough to do a fair amount of speaking myself this year, so I look forward to being an attendee this time around.
The tracks this year will be "People & Process", "Everything Connected", "Leading & Bleading Edge", "Enterprise Architecture" and a Solution Track. Far from all speakers have yet been announced yet, but I am glad to see Mads Torgesen on the schedule. It is a very interesting time in .NET with Roslyn being open sourced and looking to enter the finishing stages. On the down side he is also the only .NET speaker I see so far, which is a shame, with exciting things happening with ASP.NET vNext also. I am definately keeping my fingers crossed for someone in that space as well.
In any case, I am sure there will be pleanty of inspiring talks so I will be keeping up to date with the schedule and look forward to september.

This week I was at NDC Oslo, and besides seeing a bunch of awesome talks and having fun with equally geeky people I got to talk about building realtime applications with Firebase, AngularJS and EmberJS. It’s a topic I like, because I can give the audience something very tangable that they can try. On top of that it is a chance to build types of applications that were quite difficult just a few years ago – but now it has become almost trivial.
The awesome people behind the conference have already made the video from my talk available here.

Lately I have spent a bit of time with NDepend, who contacted me if I wanted a free license, in exchange for a blogpost. This was actually great timing on their part, as I was already thinking about giving it another go. Being completely honest I tried NDepend some years ago, and at the time I simply didn't know where to start and where I would get the most value from using such a tool. So back then I pretty much wrote it off, but have again and again heard good things from other developers who are using it.
My first thought when I ran NDepend this time around was that a lot had changed. The first thing that met me was a wizard for analysing a project, so I pointed it at my current project. This was the point I got derailed the first time I tried NDepend, because I remember being met by the code metric view which does look kind of scary - especially being new to a tool like this. Now however I was met by a dashboard, that is still complex, but a vast improvement since it gives a pretty good idea of some of the power that NDepend provides. I still can't help think that the tool could gain a lot by providing simpler guides through some key usecases though.

Its Build time again and I just finished watching Mads Torgesens keynote on day 3, where he has been talking about Roslyn and new C# features that are comming. I am really getting excited about Roslyn, with demos comming out that show how to write tooling extentions. Its one of those things that have always seemed out of reach for most things in every day development, simply because it was too much work and pain to do. With Roslyn being open sourced yesterday (by Anders Hejlsberg live on stage), it will provide options never seen before. So it is really a good time to be a C# developer.
On top of that todays demo got into some language features that the team at Microsoft are putting into C# and VB. As Mads said these are all relatively small features, but small as they might be they solve some real pains with todays C#. More...
