Aplicação: Serviços Académicos da Universidade de Aveiro

Anuncio o lançamento da aplicação SACUA ou Serviços Académicos da Universidade de Aveiro, que permite a qualquer utilizador da Universidade de Aveiro consultar os números atuais das senhas dos serviços académicos sem ter de aceder propositadamente ao PACO ou outra interface web, bastando para tal ter este programa instalado no computador pessoal.

Este software resulta de um fork de conteúdo que virá a ser integrado na próxima versão do DETI-Interact, um sistema de interação com ecrãs públicos presente no hall de entrada do Departamento de Eletrónica, Telecomunicações e Informática (DETI) melhorado por mim por forma a suportar interação através do sensor Kinect.

O SACUA pode ser descarregado no final desta página.

O SACUA é tornado possível através do Academic Playground & Innovation.

Sistemas operativos: Microsoft Windows 7/8

Colloquium of Robotics and Cybernetics

In 1998, Kevin Warwick connected his own nervous system to a computer. The deed transformed the expert in Cybernetics of the University of Reading in the world's first cyborg. The unusual and sometimes controversial English Professor is one of the presences at the Colloquium of Robotics and Cybernetics that the University of Aveiro (UA) organizes on October 13, 2012.

Colóquio de Robótica e Cibernética

Em 1998, Kevin Warwick ligou o próprio sistema nervoso a um computador. O feito tornou o especialista em Cibernética da Universidade de Reading no primeiro ciborgue do mundo. O invulgar e, por vezes, polémico professor universitário inglês é uma das presenças do Colóquio de Robótica e Cibernética que a Universidade de Aveiro (UA) organiza a 13 de Outubro de 2012.

Getting PrimeFaces mix of Selects, Objects and Converters to work

If you are having problems with the AJAX Select components from PrimeFaces when selecting Java objects, inside a DataTable or not, this solution might work for you.

Google Earth Plug-in and the ATL 10.00

While playing with the Google Earth Plug-in to integrate in a WebBrowser control of a WPF application I'm currently developing, I started getting this strange background text instead of the map/earth: ATL 10.00.

ATL 10.00

I needed to do two things to get my page working. one simple thing.

Aligning contents of PrimeFaces' PanelGrid

If you are trying to align the contents of a panelGrid and nothing seems to work (styles that you define eventually don't appear in the rendered page) then this might help you.

EJB is null inside RESTful web service

While developing my enterprise application and learning Java EE at the same time, I came to a situation where injecting an EJB inside a RESTful web service class would be the same as nothing. The EJB variable was always null.

So, what did I change to fix this?

Error creating managed object for class

Well, while developing my enterprise application in NetBeans 7.1.2 with GlassFish 3.1.2 as the application server, the following most notable error appeared and made the project unable to deploy:

Error creating managed object for class: class org.jboss.weld.servlet.WeldListener

and a bunch of other errors and exceptions.

Generated Facelets templates not applying / can't find CSS stylesheets

Using NetBeans, I created a Facelets template and a Facelets template client through the wizards provided. No changes were made to the source code.

However, when navigating in the generated template client with my browser, I noticed that the sections "inserted" (e.g, header, footer, content) were not being stylized in any way.

After a great deal of head banging onto the wall, I finally found a solution for this.

Fixing remote GlassFish server errors on NetBeans

If you are having errors when adding a remote GlassFish server to your NetBeans installation and you are sure there's connectivity between you and the remote server and all the required ports are open, a possible cause might be not having the remote secure administration enabled (which is required if you want to deploy remotely).

No Program Associated with Emptying the Recycle Bin Error

When trying to empty the recycle bin in Microsoft Windows Vista/7/2008/2008 R2 (and probably XP, though it was not tested) via the "Empty the Recycle Bin" option, the following error appears:

Adding comments in GNS3 IOS baseconfig files

If you want to write some comments in your GNS3 baseconfig files for the Cisco IOS, you can use the exclamation mark. It is mainly used for separating commands for easier reading. Everything that is written after the exclamation mark is ignored.

Here's an example:

Unable to write inside TEMP environment variable path

I stumbled upon this beautiful error when trying to re-install my PostgreSQL 9.1.3 server: Unable to write inside TEMP environment variable path.

After some research and trial-and-terror [sic], I came to the conclusion that the essence of the problem had been a tiny change I made to my system's file associations (via Notepad++).

Here's how I solved it and how you can do it too:

Running GlassFish as a service on Windows (Error 1067)

I've been trying to run GlassFish as a service on Windows:

asadmin.bat create-service

Unfortunately, that task didn't show up easy due to one little detail: GlassFish was installed on the famous Program Files folder. Other causes may just need a restart of Windows.

When starting the service, it says: Error 1067: The process terminated unexpectedly. And it really terminates.

Change Jenkins or Hudson HTTP port number

One of the things server administrators of Jenkins or Hudson CI solutions often want to do, is to change the HTTP administration port.

I'll show you how, in 4 different ways: For Windows (service), WAR file deployed in GlassFish, Natively in linux and finally, using wrapper.

It's pretty simple:

Creating KDE's Dolphin services and integrating AES Crypt into it

The main objective of this post is to give you a quick glance at how you can create service menus and plugins for use under Dolphin, the default file manager in KDE.

In order to achieve the goal, you need to know what service you want to create for Dolphin. That's where I present you AES Crypt, a nice simple application that allows you to encrypt/decrypt your files in an easy and cross-platform way. Unfortunately, the linux version lacks some features, like UI integration (for obvious reasons), and it's up to us users to make something about it.

Waiting for UDev events to be processed

A couple of days ago my netbook started taking too long to start up and giving me timeouts while processing events from UDev.
This happened during the boot auto-detection of devices in my distro of choice, Arch Linux.
I found out that it was related to my wireless adapter, Broadcom BCM4313 and a recent commit to udev.

I will present the issue encountered and a possible solution for it. I will especifically show how to do it under Arch Linux and, finally, I will leave you some useful links.
