JFokus 2013: Second confrence day

On the second day I didn't make as much notes as I did on the first. That doesn't mean that the session weren't interesting I just focused more on listening. I attended eight session on the second day where the last one was the most memorable one by Dan North but I'll go through them chronologically. Some of the text is word to word notes from the presentations and some are my view of how I understud and processed the topic in my mind.

Building scalable, highly concurrent and fault-tolerant systems: Lessons learned
Jonas Bonér told what makes systems slow and what kind of solutions can be used to speed them up or at least speed up the response to the user. 
First lesson to learn is There are no free lunches. If you use some approach it affects to something else. Some might use the phrase There are no silver bullets which means the same thing or at least that's how I undestud it.
Second topic was about concurrency. Mutables and threads isn't a good a combination…

JFokus 2013: First confrence day

This was my first time at JFokus but hopefully not last. I wasn't quite sure what to except. I had heard good things about the confrence and knew that it was quite big. It was more and better than I expected. There were over 1500 attendees and great session from beginning to end. If i get the opportunity to go again I'm most definitely going again.

On the first day I attended six sessions. I'm not going to write all my notes here but I'll try to give good summary of each session and the rest can be read from JFokus website where you can find presentation materials for both days.

Taking development to the edge This was the keynote of JFokus embedded, M2M & internet of things miniconfrence.

In the future everything is connected to each other and to the internet by everything meaning absolutly everything. Cars can share information of traffic, houses can tell if all the doors are closed and locked or the are the lights on.

Smart homes didn't succeed 10-15 years ag…

Vaadin meetup

I attended Vaadin meetup with a few colleagues on a way to JFokus 2013 and thought I should share my notes of the two. First post is about vaadin meetup that took place on a cruise from Turku to Stockholm.

I made notes of three presentations and one of them I had high expectations. There were also two other presentations that I didn't make any notes of.

Vaadin 7
Vaadin released Vaadin 7 framework the same day that the meetup was on so they had a presentation where they told about new features and future plans. I'm more of a backend programmer than UI programmer so my notes of this were pretty brief but here it goes.

Blogging from snowy Finland

First post on my first blog... Lots to say but can't deside what to say so I decided to start by a introduction of myself before we get into business.

I do software development for a living and that also happens to be a hobby of mine, what a nice coincidence. I work as a IT-consultant and I'm loving it most of the time. I get to see a lot of different environments and solutions but... there's always a but, I also see a lot that could be improved. With improvement I mean cleaner, simpler and easier to understand solutions.

I do most of my programming with Java, but I've had some experience with HTML, CSS, PHP etc. solutions in my past and in the last two years I've done some development with Groovy and modern JavaScript libraries.
Various relational databases have been part of my toolbox since I started web development with MS ASP and PHP over a decade ago. Recently I've also done development with NoSQL databases as a backend instead of RDBMS.
I haven't give…
