In search of a good Pen

I am searching a good pen. Easy, clean, since I have a very poor calligraphic skill.

I tried the following :


    Roller Ball Pens 0.5, Width of stroke: 0.3 mm

    So far the best I tried. A bit too fine and the grip isn't that good, but no big problem. 05/05/2007.


    Ball Point Pens, Width of stroke: 0.4 mm.

    The ink doesn't flow very well, looks like their "oil based ink" becomes hard.


    Ball Point Pens, Width of stroke: 0.4 mm.

    Big deception : the ink flow isn't steady some blanks and some splotch. It is sad because the shape and the grip is very good.


    Width of stroke: 0.6 mm.

    Stroke too wide for me. 10/04/2007.


    Fine Line Marker Pens 1.2, Width of stroke: 0.5 mm

    Stroke too wide for me. 05/05/2007.


Semantic Web, RDF and URI in the real world

My interest in Semantic Web has slowly diminished as so few applications and data are available. But I keep an eye on it and from time to time, I read an article.
This time : Cool URIs for the Semantic Web a note from the W3C. It is about the way you should serve content and uses URI for RDF, HTML and "Real Things". Conclusion is : there are no good way to do it, they present 2 very different solutions among others. So since both solutions are far from perfect, every one is making his semantic web.

One strange point : "a naming scheme should not confuse things and the documents representing them.". I have a mixed feeling about this. It states that a "Thing" should have an URI, but that URI should be distinct from the URI of the document describing the "Thing". So what is the point of having an URI if it just redirect to a real document. Just for reference ? Then why should it return something at all ? It is more practical. Sure. Then it looks like a mess resulting from theoretical and practical views.

Among the articles I read and didn't blog about :
- Some editors/publishers may see a value in adding metadata to their content (articles, reviews ...). This would provide more content to be retrieved with semantic Web applications.
- Computer will be able to add more significant metadata automatically. Normal users would just have to validate.
- Data-portability, will raise the need to detach the data and replace the format (HTML/CSS) with metadata. So one will be able to move his data from one site to another, each one providing its own format and applications.

No doubt that we are going to benefit from the semantic web on a large scale one day, but not today !


Easy creation of Java EE application

A bit like WaveMaker : Java EE Spider will allow you to create a Java EE Web application.
From the screenshots it seems to be "wizard driven".

They have controversial view about Model Driven Development, with the UML diagrams and code generation tools. I don't agree that MDD isn't agile, it is more in the way it is used and the culture associated.

It looks like a wave of UI-First Software Development things.

I feel like we are trying to establish a continuum from requirements and prototypes to final products, using successive iterations.


WaveMaker : easy web app creation

Good interview from Redmonk about WaveMaker : RIA Weekly #11 - WaveMaker.
So WaveMaker is an easy to use IDE and Framework to build web application. It is Open Source and based on Open Source : Spring / Hibernate / DOJO ... They gets data from Databases as well as WebServices.
- They use WaveMaker to build WaveMaker
- They point out the scattered state of AJAX libraries (DOJO, jQuery, Prototype, Scriptaculous ...) opposed to the clear path offered by Adobe or Microsoft.
- As a workaround they try to provide a level of abstraction above all those libraries, so you are not tied on a specific one.
- They mention Appcelerator too, wich is more database driven.
