Tijdens het LAC-2013 heb ik een presentatie verzorgd over Dynamische Architectuur Visualisatie. Tijdens deze presentatie heb ik laten zien hoe ik schetsen in SVG formaat gebruik als visuele ondersteuning van een presentatie. De svg versie van deze presentatie zie je hieronder. De volgende pagina biedt de mogelijkheid om slides van (more...)
The following is only relevant if you run Mendix on-premises. If you do, you probably have standard monitoring tooling that you use to monitor all your applications.
Mandrill is the transactional email service by the same folks who do MailChimp. I've written about it before, in particular how to use the mandrill-rails gem to simplify inbound webhook processing.
Mandrill webhooks are a neat, easy way for your application to respond (more...)

There are some good ruby gems available for dealing with OAuth 2.0 and talking to Google APIs, for example:
It is a pretty common pattern to branch depending on whether a query returns any data - for example to render a quite different view. In Rails we might do something like this:
query = User.where(deleted_at: nil).and_maybe_some_other_scopes if results = (more...)
So the best swag you can get from a technology conference is code, right? Well RedDotRubyConf 2013 did not disappoint! Thanks to some fantastic speakers, my weekends for months to come are spoken for. Here's just some of the goodness:
It all comes back to connectivity. Om Malik (TWiST #327 @00:37:30) has a brilliant characterization of the true impact of the internet:

Good news, I am back in blogging :) In recent years I have spent my time primarily on eazyBI business intelligence application development where I use JRuby, Ruby on Rails, mondrian-olap and many other technologies and libraries and have gathered new experience that I wanted to share with others.
Recently I did eazyBI migration from JRuby 1.6.8 to latest JRuby 1.7.3 version as well as finally migrated from Ruby 1.8 mode to Ruby 1.9 mode. Initial migration was not so difficult and was done in one day (thanks to unit tests which (more...)
Megar (“megaargh!” in pirate-speak) is a Ruby wrapper and command-line client for the Mega API.
In the current release (gem version 0.0.3), it has coverage of the basic file/folder operations: connect, get file/folder listings and details, upload and download files. You can use it directly in Ruby with what I hope you'll find is a very sane API, but it also sports a basic command-line mode for simple listing, upload and download tasks.
If you are interested in hacking around with Mega, and prefer to do it (more...)
Mandrill is the transactional email service by the same folks who do MailChimp, and I've been pretty impressed with it. For SMTP mail delivery it just works great, but where it really shines is inbound mail handling and the range of event triggers you can feed into to your application as webhooks (for example, to notify on email link clicks or bounces).
The API is very nice to use, but in a Rails application it's best to keep all the crufty details encapsulated and hidden away, right? That's what the mandrill-rails gem (more...)
There are a lot of people who think camera’s in tablets are a bad idea. “Nobody should be allowed to take pictures with a large tablet in front of their face.”
But if you can think outside of the traditional camera box for a moment, and start to think what’s possible if you combine a really portable computer with a decent camera, you’ll soon see interesting new possibilities.
Just a couple examples:
And that's a compliment!
Wow. This year we mark the 20th anniversary of the Visual Basic 3.0 launch way back in 1993.
It's easy to forget the pivotal role it played in revolutionizing how we built software. No matter what you think of Microsoft, one can't deny the impact it had at the time. Along with other products such as PowerBuilder and Borland Delphi, we started to see long-promised advances in software development (as pioneered by Smalltalk) become mainstream reality:
While converting my old wordpress blogposts to markdown i read some of my old posts. For example, here is what i wrote when Apple launched the iPhone in 2007:
In a couple of years mobile phones will be powerful enough to replace laptops for most common computing usages. You won’t need a separate laptop. You walk around with your mobile phone, in the office or at home you put it in a docking station, attach a keyboard and a bigger display, and you have all the computing power you need.
Some news this last week indicates we’re getting close (more...)
