Goto day 1 roundup – distribute all the things

by DotNetNerd 25. September 2014 15:21

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.


Goto keynote "Does the browser have a future"

by DotNetNerd 25. September 2014 09:59

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.


NoSQL the Sequel, now with SQL - the revenge of DocumentDB

by DotNetNerd 9. September 2014 14:23

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.

Providing feedback

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.




Microsoft track at GOTO

by DotNetNerd 14. August 2014 11:00

8486791170_005e569bec_b 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.

Robust integration with Redis on Azure and Polly

by DotNetNerd 13. July 2014 12:56

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

Redis on AzureThe 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.


NDC talk: “Cloud beyond scaling: realtime webapplications”

by DotNetNerd 8. June 2014 09:37

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.

NDepend review

by DotNetNerd 2. May 2014 15:13

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.


Build 2014 announcements for C#

by DotNetNerd 4. April 2014 17:38

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...

Fun with Mocha.js and Should.js

by DotNetNerd 20. February 2014 14:13

Since the amount of javascript in an average website has exploded, the need to unittest that code has become apparent. I think we are still a bit behind in this respect, as I often hear from people don’t know what “the right way” is to create such as setup. Sadly this seems to mean that they never got off the ground and skip testing clientside. Without starting any kind of war on this, I think most of us like at least some number of tests and the option to do TDD.

Well I may already have painted myself into a corner, as I don’t claim to know the one and only “right way”, but I have found a way of going about it that I really like and have fun with. Shortly put, I have been playing around with Mocha.js and Should.js – supported by the Chutzpah test-runner and testem that allows a light weight way of running tests while doing TDD.


Realtime data displays with Firebase

by DotNetNerd 27. January 2014 10:34

images Lately I have been working quite a bit with displaying data in realtime on the web. I was even lucky enough to get the chance to talk about it at the Warm Crocodile Developer Conference – showing off how this can be done from your favorite SPA frameworks AngularJS and EmberJS.

One of the things I really like about these kinds of solutions is that all of a sudden it has become easy to do something that hardly was possible just a short while ago. All thanks to websockets, and technologies that utilize it. Firebase is just one such tool, and in many cases you may want to go low-level and build your own backend with eg. SignalR. It is still not too much work, and probably the route to take for most larger applications. However when Firebase is sufficient, life cannot be much simpler for getting things done.
