netbeans – it doesn’t start in ubuntu

I’ve installed netbeans on Ubuntu 16.04 from the official repositories.

sudo apt-get install netbeans

It opened correctly but I noticed it didn’t have all the plugins I required. First, i tried to install them from “Help | About | Plugins”. It complained about not having permission to extract/install the plugin. So, I closed netbeans and started it with root user, then it finished adding the plugins but when I tried to start it again with my regular user it wouldn’t boot.

I decided to remove netbeans repositorie’s version and instead download and install manually.

sudo apt-get purge netbeans

I’ve downloaded and extracted the OS independent full version of netbeans on my home directory ‘~/Apps/netbeans/8.1’ but when I tried to start it from the terminal nothing happened.

As it happens, the problem was that when I started netbeans as root it changed ownership of some files on two folders: ~/.netbeans and ~/.cache/netbeans

The solution is to delete those folders (those will be recreated when starting netbeans) and start netbeans again as a regular user.

sudo rm -rf ~/.netbeans ~/.cache/netbeans



Ubuntu – Instalar el cliente de spotify para linux

Es conveniente mencionar la relación que presenta el uso de las tecnologías de
información y comunicación (TIC) con la música y los jóvenes. En la actualidad, los jóvenes
emplean diariamente las TIC para incrementar conocimiento, buscar información, relacionarse
con otras personas o para divertirse. En la música, las TIC influyen en la manera en que ésta se
crea, se produce y se difunde; éstas también han generado cambios que ofrecen gran cantidad de
opciones musicales, desde la composición hasta el consumo de la música, y que gracias a los
medios de comunicación han permitido la distribución musical masiva, inmediata y global

En la página oficial de spotify nos dice como debemos instalar el cliente de spotify en linux

  1. Agrega esta línea a tu lista de depósitos al # editar tu /etc/apt/sources.list

Al parecer esto se debe a algún problema con sus servidores DNS, para instalarlo debes utilizar en vez de


JIRA – El campo de Reoulución no es actualizado

Screenshot from 2013-10-15 08:38:37

Estamos probando JIRA junto con Stash para administrar nuestros proyectos y el código fuente.
Lo que me gustó de la integración con Stash es poder “cerrar” una incidencia abierta desde un commit.
No se que haya modificado en nuestro servidor, pero las incidencias no estaban siendo cerradas, sólo se encontraban en un status “done”. Para corregirlo tuve que modificar el flujo de trabajo que utilizaba el proyecto, agregando una “post-function” que actualizara el campo Resolución a las transiciones que derivaban en el status “done”.


Acer Aspire 5745 – Battery indicator problem

I’ve just installed Fedora 15 on my laptop Acer Aspire 5745 and works great, but the battery indicator applet always shows that it’s 0% charged wether it’s connected to ac or not. I found this post which explains that it is due to a BIOS error which has been fixed, therefore to solve this problem you need to update the bios. Acer provides an update software which, sadly, only runs on Windows or DOS. I thought of doing it from a virtual machine, but that wouldn’t work because the VM has its own BIOS. So, the solution is to run a DOS version –freeDOS– from a live-usb and run the acer software as explained here.
You will need to:

  1. download unetbootin and make the file executable with the command chmod a+x unetbootin-linux-XXX
  2. execute unetbootin with admin privileges, sudo ./unetbootin &
  3. select FreeDOS in the Distribution
  4. select USB Drive in Type and your USB device in Drive
  5. copy the Acer update software for DOS in the USB
  6. Restart your laptop and boot from USB, enter the command prompt and run the utility

Now that your BIOS is updated, the battery indicator should work fine.

Note: This surprisingly also fixed the eject button, now it’s working.

BIRT – File Not Found Exception (Permission Denied)

I had a BIRT report working until I did an upgrade. While I was trying hard to find the root of the problem, I thought I should try the debug option, I had never done this. I thought it would be easy. I set up my breakpoints and clicked Run->Debug Report but the following exception was thrown:
Caused by: /rptComparativo.rptdesign.html (Permission denied)
I found the solution here.
Right click the Report in the Navigator Window (Open it if necessary) and select Debug As->Debug Configurations… You should have a debug configuration created for you with a name like “New_configuration”, make sure that Temp Folder is “/tmp” and click Debug. Once you start debug from this window, you should be able to do it from the Run->Debug Report menu in subsequent occasions.

GWT – No source code is available for type

I’m using GWT and SmartGWT in multiple projects. Since I had to reinstall Eclipse and all its plugins, Google Plugin for Eclipse included, I got an upgraded GWT SDK.
Many projects I have were failing to run with the following exception:

No source code is available for type

I found the solution here.

You can’t use GWT 2.3 yet.

ant4eclipse – Linked Resource does not exist!

I had to change from Ubuntu to openSUSE, at first everything seems to work smooth until I found this little glitches. I’ve tried just to copy my Eclipse installation from the backup to my brand new OS but it didn’t work so I had to install it again (uncompress it).
One of my worst headaches is solving project dependency but fortunately I found a way to ease this process.
With the migration I moved my files from /home/vladimir to /home/cirovladimir,  my eclipse workspace included. This led me to an error when I was trying to run the ant file I use to solve dependencies. The error description wasn’t very helpful, it just said “Linked Resource does not exist!”. I found this post which proposed to use the development version of ant4eclipse instead of the stable release, so I did it. I tried again and this time the error was more clear “The linked resource ‘/home/vladimir/Projects/Eclipse/tsj.estadisticas.model/src/tsj’ in project ‘tsj.estadisticas.web’ does not exist.”. This allowed me to spot the problem and change the path in the hidden file “.project” -which contained the references- accordingly.
