I’ve been using When can I use… quite a bit recently. It enables you to quickly determine if a html5, css3 or svg feature is enabled in all the different browsers. Very useful.

I’m working on a small javascript library to use svg drawings for presentations. This would allow you to display a single svg drawing similar to normal presentations on slideshare or speakerdeck. You can see the current state here: SVG Presenter test. I wanted to see if you can use webfonts in an svg drawing in [...]

I create most of my presentations using Inkscape (here’s an example: Presentation: Introduction to Scrum). This is quite a bit of work, as i need to export all the separate images, and import them into LibreOffice Impress. I’ve created a small javascript script that can be used to directly use the svg image as a [...]

One of the main goals that Software architects try to achieve is to design solutions that will last a long time. You’ll often hear an architect say that the product will have a life span of about ten years, and that all technical choices should support this goal. This means that any framework you select [...]

Not too long ago enterprise applications looked like this. All data stored in a single database. Data integrity was no issue, database links between all tables made sure of that. You could easily link between tables in different domains. For example, orders would link to products and customers. Unfortunately, most companies didn’t have a single [...]

Lots of news on Chrome OS today, but nothing to suprising as far as i can tell. Chrome OS is basically just an operating system than boots straight into a (full screen) browser. All your apps will be web apps. Seems logical. Most of the time i just boot my computer to get online: read [...]

Stefan Tilkov blogged on the recently created SOA manifesto. He’s a big proponent of using REST(ful HTTP) for achieving SOA goals. One of the reactions he got on a previous post on this topic states that REST and SOA are incompatible, as REST is not about services but about resources or documents (with a standardized [...]

I’m convinced that open webtechnologies are suited for more than just web page development. I don’t see why you can’t write desktop applications using open webtechnologies. So, I’m also pretty optimistic about what Google is trying to do with Chrome OS. Many of the problems people currently see with Chrome OS are in my opinion [...]

Firefox 3.5 has been released. Not everybody is excited about this release, but most reviews are quite positive. In my opinion, the enhanced javascript performance is the most important improvement, but features like the html 5 video and audio tags, offline support, @font-face, geolocation support and cross site XHR are not to be underestimated. As [...]

I’ve just been watching the google wave presentation. Pretty amazing application, it’ll probably scare the hell out of a number of communication software providers. But what’s even more amazing is that it’s almost entirely build using HTML 5. Just one feature needs the Google Gears plugin: drag and drop of desktop resources to the web-page. [...]
