Juri's Writings: Implementing a REST API with node.js
http://juriswritings.blogspot.com/2015/04/implementing-rest-api-with-nodejs.html
A blog by Juri Urbainczyk Juri on Google. Wednesday, April 8, 2015. Implementing a REST API with node.js. It was quite clear that the API should be REST with JSON as transport protocol. Unfortunately, we only had less than 4 weeks to design, implement and test the mock API. Thus, only a very lightweight technology could make this possible, like node.js. Var http = require('http');. Var express = require('express');. Var url = require( "url" );. Var path = require("path");. Var fs = require("fs");. So, in...

Juri's Writings: An HTML5 canvas component for ExtJS 4
http://juriswritings.blogspot.com/2013/06/an-html5-canvas-component-for-extjs-4.html
A blog by Juri Urbainczyk Juri on Google. Tuesday, June 25, 2013. An HTML5 canvas component for ExtJS 4. As I described in another post. ExtJS 4 features components for graphics ("Ext.draw.Component") which are based on the standard HTML SVG tag. But what if we liked to use a canvas tag? ExtJS does not bring one of those - thus we have to create one. Picture 1: Solar system simulator written with the canvas component. And now, the most interesting part of the source code:. Extend: 'Ext.Panel',. ThistempC...

Juri's Writings: Devoxx 2013 - The coming of lambda
http://juriswritings.blogspot.com/2013/11/devoxx-2013-coming-of-lambda.html
A blog by Juri Urbainczyk Juri on Google. Tuesday, November 19, 2013. Devoxx 2013 - The coming of lambda. This year, there was no unique theme standing out. The hypes of the years past, Mobile, Cloud, NoSQL, BigData, are now regarded as standard. There were still presentations about those topics, but they are “normal” now. This of course is a good thing, although great emotions and extraordinary news are missing. Java 8 expected with Lambdas and support for parallel execution. Public class MyListener {.

Juri's Writings: Devoxx vs. JavaZone
http://juriswritings.blogspot.com/2014/09/devoxx-vs-javazone.html
A blog by Juri Urbainczyk Juri on Google. Tuesday, September 23, 2014. Devoxx vs. JavaZone. Every now and then I get queried which of the Java and Web conferences in. I would recommend. Often, the most sensible answer seems to be: “the one closest to you”. Nevertheless, since I visited JavaZone in. In September 2014, I think it may be time to make a thorough comparison after all. But which are the criteria? The number of rock star speakers? The volume of soft drinks available for free? If you have picked...

A blog by Juri Urbainczyk Juri on Google. Saturday, December 22, 2012. ExtJS Game of life – testing the Ext.draw library. I always wanted to check out the ExtJS graphics library (Ext.draw) and thus I decided to implement the Game of Life in ExtJS as a kind of prototype. The following screenshot shows the results, a running game of life on a 40x40 grid. A running 40x40 game of life in ExtJS. Details about the Game of life can be found here: http:/ en.wikipedia.org/wiki/Conway%27s Game of Life. In order to...

A blog by Juri Urbainczyk Juri on Google. Monday, August 27, 2012. Textfield with an image: how to write a Sencha Touch 2 component. Let's assume we'd want to write a component, which displays a string together with an image. This would come in handy, if we need to display the name of a customer (e.g. 'Pfefferminzia') and it's logo. The following picture shows the component in action - in the second row of the dialog. Extdefine("myapp.view.CustomerDisplayField", {. Extend: 'Ext.Container',. ThissetHtml('...

Juri's Writings: Should Domain Objects contain business logic?
http://juriswritings.blogspot.com/2012/07/should-domain-objects-contain-business.html
A blog by Juri Urbainczyk Juri on Google. Sunday, July 1, 2012. Should Domain Objects contain business logic? Should all of it be in the service functions or should all logic go into the domain objects or should we have a mix? The picture below shows two services using two domain objects each. One domain object is used by both services. Should the logic be distributed? It can get even more complicated, since domain objects may also call one another, thereby using the logic of the other domain object.
