Striving for competence

A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

Engineers ... experts and the hidden need.

First of all I have to make my biggest thanks to the author of this video, because is the perfect exemplification of what happens in reality.

The real problem is that engineers (I know a bit on them being part of the professional order) usually really think they are experts that know how to do all.
Engineers often consider themselves modern “Leonardo da Vinci” able to cook, build, plan, draw and whatever and often, as in this case, they end up falling prey of the old saying “Never argue with a fool, onlookers may not be able to tell the difference”.

In fact, engineers usually like to get tangled in these sort of discussions to be able to demonstrate their expertise in “drawing red lines” and remarking that others do not know geometry.
Unfortunately this is not the proper way a real professional should behave.
Here the customer is presenting himself not with the need but with his “better” solution, usually because asking for help is much more difficult and generically customers have the approach “I'm paying you and you have to do as I ask”. They need to be in control.
The real expert has to be able to explain that if the customer is looking for a professional he should before describe the need and letting him propose the solution, so the right question here is “why?”.
Being able to go to the root of the problem and not letting the customer draw you into useless discussions. “You have a problem and you need a professional solution? I will be your expert!” “You have a problem and you have your solution? Ask the expert that came up with the solution to implement it for you!”.
This is why many project fail, because few people were asking the right questions or simply refused to stand up and leave.
Again thanks for this wonderful video.

FaceRig - New Indiegogo campaign for realtime CGI rigging

It has been a passion of mine, but never had the time to dedicate effort.
This project should make things easier.
Hope that there will be a SDK to create own characters.
Take a look at it and consider to perk for it.

JBoss 7.1.1 + GeoServer 2.2.5: logging

To enable correct logging of GeoServer in a JBoss 7.1.1 installation we'll need to modify the previously defined jboss-deployment-structure.xml

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
            <module name="org.apache.log4j" />
            <module name="org.slf4j" />
                    <path name="com/sun/imageio/spi"/>
                    <path name="com/sun/imageio/plugins/common"/>
            <module name="" />
            <module name="org.jboss.ironjacamar.jdbcadapters" />

Than you need to set the following jvm-option in the host.xml file: GEOSERVER_LOG_LOCATION

 <server name="geo1" group="geo-server-group" auto-start="true">
            <jvm name="default">
                <heap size="128m" max-size="512m"/>
                    <option value="-DGEOSERVER_DATA_DIR=/home/jbossas/geoserver_data,-DGEOSERVER_LOG_LOCATION=/var/log/jboss-as/geoserver.log"/>

In the example you also see that is possible to define a data dir in the same way.

PHP library for calling WSO2 API manager publisher

My need is to create an application that manages the creation of API from a single central point (a PHP site).

The WSO2 API manager has some interesting REST API that can be used to create programmatically an API.

To manage these API better I've developed (still in development) a library that calls the API manager, manage errors and wrap the whole up.

If you need it here is the link to github.

WSO2 Tutorial - BPS

In this tutorial of the WSO2 path I'm working with the BPS version 3.0.0 and WSO2 Developer Studio version 3.0.0.

The objective of this tutorial is to show how to implement a simple process and deploy it in the BPS.

I'll use here a standard default installation of the server (no external DB for process management and so on)

TEIID 8.1 tutorial - Part 15 - Support Update

In this new tutorial of the TEIID series I'll show how to update the original table from the VDB view.

Usually when operating with TEIID designer the "orange" view model proposes just to read/select from the source table.

To be able to Update/Insert/Delete from the original table we must enable the "Support Update" checkbox as shown in the figure below.

In the video I'll show the whole procedure.

WSO2 Tutorials

I'll start a new tutorial line dedicated to the WSO2 product suite.

Here is what I'm preparing:
1) Business Process Server - example process and deploy
2) API Manager - publishing of an API and usage from the store
3) API Manager - TEIID SOAP service publishing

More will come.

GeoServer 2.2.5 + JBoss 7.1.1 and Oracle

As I posted some time ago, I'm using GeoServer version 2.2.5 on a JBoss 7.1.1 installation; now I'm working with an Oracle Database so I've added the Oracle extension. And added it in the "$WAR/WEB-INF/lib/" the jar that is downloaded as a separate package (mind to download the same version for the GeoServer you are using).

I had this problem accessing oracle tables:

The problem is due to a classloading mechanism of the AS.
