JS CodeRetreat #3 Highlights

First and foremost I would love to thank all the attendees that made the #jscr #4 such a cool event, which obviously made it worth spending another Saturday on working on our coding skills. And of course I would love to thank Martin Ruprecht who facilitated the event with me and Irene who has […]

Test public API, not implementation details

There are good reasons why programmers perform tests themselves in contrast to letting an external testing department (QA) perform the tests. The programmer is able to discover errors in code and in general design decisions much faster and can react immediately, as one might say, the feedback loop is very short. On the other […]

EmbedJS 0.2 and AMD

During JSConf.eu, we released EmbedJS 0.2. That release was mainly about a fundamental architectural change: the move to the AMD pattern for our features. Let me explain why we decided to do this, why we think this is a big step forward and what this means for the user.

Creating a persistent Dojo Object Store

As of version 1.6, dojo comes with the new Dojo Object Store API. This is an awesome thing, as it greatly simplifies the work with data stores in Dojo. Everybody who had to do with the traditional dojo.data API felt it was overly complex and hard to use – this has finally changed now. There […]

Using IndexedDB on Firefox

As Firefox 4 is now stable, chances are that the async IDB (IndexedDB) API is not going to change anymore. But IDB is not localStorage – it can be a major pain to work with. So, here is a guide on how to use IDB in Firefox as a key-value store. TL;DR There is example code […]

Object-Based Inheritance For ECMAScript 5

This post describes a simple, object-based inheritance system for ECMAScript 5 compliant runtimes. First, I will explain how inheritance works in JavaScript/ECMAScript, and how inheritance chains are built usually to give you a deeper understanding what I’m talking about. After that, I’ll introduce the new Object.create() method found in ECMAScript 5 and an inheritance system built on […]

Explaining EmbedJS

Last week, we tagged the current state of EmbedJS 0.1. This is a large step for us, and something we have been waiting for and wanting to do for a long time. And with doing so, the need arises to answer a lot of questions – and we better start sooner than later. So, here […]

indexedDB Updates – FF4.09b

IndexedDB is all the buzz right now, but it is pretty hard to find information about it’s implementations. In addition to that, the impls change on a weekly basis. So I figured it would be nice to summarize every now and then what has been happening around IDB in the last time. And as Mozilla […]

BarCamp Munich 2010 – seen through JavaScript and mobile eyes

First and foremost big thanks to the organizers and sponsors of this awesome BarCamp. It almost seems as if BarCamps have already passed their tipping point, but still every time I discover new and interesting things, I meet people who attend for the first time and are excited about it, which makes it really awesome […]

We are going to give four cool talks David Aurelio (of TouchScroll fame) – Interface Styling & Scripting for WebKit Mobile Jens Arps (our storage expert) – The hitchhiker’s guide to […]

Forgotten tricks for iPhones Safari

Safari om the iPhone is an incredible powerful browser and comes with a whole bunch of features. Besides the amazing support for CSS3, a superfast rendering engine and great JavaScript support, there are a few hidden gems I want to explain in this (and maybe following) blogposts. If you are interested in mobile web development, […]

One var statement for one variable!

JavaScript allows to comma-separate multiple variable declarations, like so: var i=0, j=1 . Declaring multiple variables using one var-statement accross multiple lines is a NO GO! I consider this evil. And I learned it the hard way. It might look pretty nice, looks like less code and more efficient. But it definitely is not so […]

HumanApi – the browser in the real world

During the Oredev speakers dinner last November, I was having an interesting discussion about the car industry and how Google in one swipe mangled up the turn-to-turn navigation market. During this discussion and other interesting conversations at the following JsConf, it it became more and more clear that we (web developers) should be able to […]

Dojo.workshop(“Haifa”) – the summary

August 9th was the day for the first Dojo event in Israel and thanks to Yoav Rubin from IBM Research Labs in Haifa, we were able to hold the event in the great Auditorium of the amazingly located IBM building in Haifa. To give you a little impression of what kind of working environment the […]

Some for-loop considerations

We have been developing some coding style guide lines to produce better code and make our code easier maintainable and portable. Also thinking about code inspection tools and continuous integration techniques which analyze the code will profit from a well defined and verifyable style. While discussing a rather simple rule I thought this might be […]
