[HOW TO] How to install NetBeans 6.0 on Ubuntu Linux

In the previous post had given the news about the release of version Final
Netbeans 6.0. And surfing the net a bit, I saw that there are many who do not know how to install this magnificent IDE (Integrated Development Environment) from the file extension. Sh is available for operating systems GNU / Linux.

Thus, this paper will describe briefly, and step by step ", the way how to install Netbeans IDE 6.0 on your favorite Linux distribution, including Ubuntu.

But first, it is important to note that, for proper or optimal functioning should be considered the system requirements, taking into account, of course-the minimum requirements in terms of Hardware and Software concerns.

Among the most important, to avoid installation problems, is to have our system installed in the Java SE JDK version 1.5.0_14 (5, Update 14) or higher (including JDK 6, Update 3).

Let's go to the above:

1) Download Netbeans

As is already known, NetBeans is characterized by providing "packages" downloads, which are not other things that the base of the IDE with additional tools, which categories are: Web & Java EE, Mobile Applications, Java SE, Ruby, C / C + +, all in one (full version).


As in the first instance, we downloaded the file varies according to the particular needs of each. Personally, I recommend downloading the full version (all packages) to make it available at any time.

can download the full version with:

~ / $ wget-c descargas/netbeans6.0 http://download.netbeans.org/netbeans/6.0/final/bundles/netbeans-6.0-linux.sh

2) Installing NetBeans

2.1) Once downloaded the file, proceed to execute it as follows:

~ / $ sudo descargas/netbeans6.0 netbeans-6.0-bash linux.sh

Notes that, if all goes well, will have output like this in the terminal:

~ / $ sudo bash descargas/netbeans6.0 netbeans-6.0-linux.sh
Password :
Configuring the installer ...
Searching for JVM on the system ...
Extracting installation data ... Running the installer wizard
...

And then, you get the wizard that will guide you through installation.


2.2) note that the default installation of the full version, install all packages:


If you only need one package individual, such as Web development and Java EE, or otherwise do not have much disk space, proceed to customize the installation by clicking on Customize ...

so selected packages required for Web Development with Java EE + Apache Tomcat.



2.3) Accept the License.

Since NetBeans is governed by the terms of the GNU GPL V2, we can not agree more ;-)
accept it

2.4) Installation Folder.
note the default location for the installation of NetBeans is / usr/local/netbeans-6.0 , we can change it if they want.
Similarly, if we have two or more can choose JDK's right for our IDE.


As we choose to install Tomcat (in preferences), we can change the location of the folder that has by default.

2.5) begin the installation

For that, see a summary of what will be done in the installation and immediately start it.





If all Installation went well, then observe:


3) Running NetBeans

Once installation is complete (in the folder you specified), run the IDE.

Assuming the installation folder is not changed, execute the following:

~ $ / usr/local/netbeans-6.0/bin/netbeans




Simple, right ?
now to schedule! xD

NetBeans 6.0 is now available

With a timely worthy of imitation, today released the version 6.0 of NetBeans.

NetBeans IDE is a free , ie Integrated Development Environment Open source software developers. So that we can get all the tools you need to create professional desktop, enterprise, mobile applications and also for the Web, using this programming language Java, C / C + + and even Ruby. The concerned IDE runs on many platforms including Windows, Linux, Mac OS X and Solaris, it is easy to install and use.

NetBeans version 6.0 includes significant enhancements in addition to new features, including a rewritten infrastructure completely from the editor, support for multiple languages, new productivity features and a streamlined installation process that can install and easily configure the IDE to suit our needs exactly.

This is good news no doubt for those who are immersed in the world of software development. More so for those expecting the launch of this new version (like me).

Soon I'll be describing in a little more detail about the new things that bring this magnificent tool.

No more to say at the moment, I invite you to download the brand new version .

Physics

In this post I will talk about one of the open source projects that caught my attention, because its main purpose is to provide libraries that allow us to simulate, taking into account the field of physics, the behavior of various objects and interactions that may exist between them, when, for example, there is a collision, or free fall acceleration due to a force, etc.. The project in question is called Box2D .

Box2D physics engine is open source, written primarily for games. As the name suggests, Box2D is purely a 2D engine. However, it is a project that has grown beyond its beginnings in which was limited to simulation, and can now handle convex polygons and other shapes available in the not too distant future.

Examples of features that provide the libraries Box2D, the next animation allows us to move various objects such as boxes, spheres, pendulums, among others, simply by using the mouse. You use the directional pad (<- y ->) for a change of scenery.

As you see, the demos of these libraries can be challenging to understand some concepts. It also can be used to create some animation or application related to the field of physics in 2D.

Days Ubuntu geek in Bolivia, November 2007

The Ubuntu Local Community Bolivia last few days is preparing a series of events to present and disseminate the new version of Ubuntu: Gutsy Gibbon.

Thus, after several days of organization, the Ubuntu community, present in the city of Cochabamba, has presented the following talks at the Universidad del Valle :

#	Who	Topic
T1	Ernesto Rico Schmidt	Introduction to Free Software and Ubuntu
T2	Ramiro Davalos	Tuning Ubuntu
T3	José Manuel Ajhuacho	Computer Security and safety information?
T4	Luis Alberto Aviles	Customization Guide GNOME desktop
T5	Benjamin Perez	Version Control
T6	Juan Jose Olivera	Environments programming

For reasons of force majeure and very beyond our control, the talk had to give in Faculty of Science and Technology UMSS, was suspended.

But activities are far from over (at least for two days), and that on Friday 23 November, will also feature talks and cited in Bolivian Catholic University in the city of Cochabamba.

Similarly, and as the last day of activity this month, on Saturday November 24 workshop will be held on installation for anyone who is willing to have Ubuntu Linux on your PC. The only requirement to participate in this workshop is to be registered to book a place with the respective relevant data from your computer.

And how could it be otherwise, members of the Ubuntu community resident Bolivia in the city of La Paz, are also preparing some talks, they will take place on 23 and 24 November.

• For more details about the event in the city of La Paz in: http://guglux.udabol.edu.bo

• can also get more information about the activities mentioned in the wiki the Bolivian Ubuntu Team .

Thus opens new horizons, new challenges for hackers to find some xploit and leverage existing vulnerabilities. Although who knows, we might try:

Login: admin Password

Or in another case, a Linux user could propose a solution with the command:

$ sudo rm-f / dev / panties

Maybe it could work, would not require much effort.

While the situation may inevitably become "critical" to some if the password were to expire at some point xD

cache: www.mipagina.com

• To find an article or publication that contains the word "software" in the URL, whether these pages html, jsp or php , also in the title has the word "ubuntu linux", the search would be:

inurl: software (html known for some?. Could it be that there could be some way to make such tricks with the form? Well, right there

[HOW TO] How to turn "what I'm listening to" using XMMS and aMSN

few days ago I did an upgrade of my system, creating a new partition to allow more space for my / home on my Ubuntu distro. To this end, we had to be formatted before installing, which is why I lost many of the features that were added prior to the various programs I installed :-(.
Well, now I take the liberty of creating these little guides for those in need, while restoring the particular characteristics I wanted for some applications.
On this occasion I will give know the steps necessary to activate the plugin for aMSN that allows us to display the song you're listening to (the nick shown below) using XMMS .

1) xmms-infopipe


For our XMMS
provide necessary information to the plugin that we just installed, we need xmms-infopipe
~ $
sudo apt-get install xmms-infopipe
Once installation is complete, restart xmms (the close and reopen).


2) Enable the plugin

proceed to enable the plugin installed just for xmms. By right clicking on the application, select the menu (Options -> Preferences -> General plugins) the plugin
infopipe
and check the box that enables: 3) Download the plugin need

music download music plugin called Official Site

aMSN project. Once
unloading, proceed to execute the following command:

~ $ sudo unzip music-1.5.zip-d / usr / share / amsn / plugins / This, copy 'music' in the plugins folder of our aMSN.

4) Enable and configure the music plugin



aMSN enable the plugin select the menu "
Account -> Selector
plug-ins" Music item, then pressing the button
Enable.
Once enabled, we configure it to work properly. In the same previous window, click on the button Set and the list of players Supported music select XMMS, see if the check box "Add to the personal message song" shows that actually is on. The "
Check new song every? Seconds"
specifies the time interval to be used as a reference to update the song displayed. That's all, and if you forgot a step, the plugin will work immediately. The result is something like this: Now you can show all your contacts what song you're listening xD.

[HOW TO] Installing Ubuntu pgadmin postgres and

are several reasons why I write this little
How To
, the second of this blog. One is the growing interest from some friends in the raid on the "Linux world, particularly in the use of Ubuntu. This little guide is limited to explain the installation of pgadmin
, a simple graphical tool, but widely used for the design and maintenance of databases in postgres. Also, explain the basics of installation and operation of one of the most popular DBMSs: PostgreSQL

.

It also rescue this guide can be used in versions 6.10 (Edgy Eft), 7.04 (Feisty Fawn), 7.10 (Gutsy Gibbon) and in fact be with the version 8.04 (Hardy Heron) of Ubuntu Linux .

NOTE: For example, user name, I'm using the account that I have in my machine and called Luix, which also has administrator permissions. In your case, it is more likely to be another ;-) Let's go to the above, do so in an elegant and interesting, using a terminal ;-)
1) Installing PostgreSQL
relatively important as detail- - be installed PostgreSQL version 8.2


Luix @ machine: $ sudo apt-get install postgresql-8.2

This command will install from the repositories that have -en nuestro caso, Ubuntu - los paquetes: libpq5 postgresql-8.2 postgresql-client-8.2 postgresql-client-common postgresql-common, si es que no lo tenemos instalados.
Una vez instalado postgreSQL, necesitamos acceder a la cuenta postgres.

luix@maquina:$ sudo bash
root@maquina:# su postgres

Hecho esto, nos aparecerá un nuevo prompt:


postgres@maquina:$

Ahora crearemos un usuario para las Bases de Datos, usando el comando createuser seguido del nombre de usuario que necesitemos, en mi caso crearé el usuario luix:

postgres@maquina:$ createuser luix
¿Será el nuevo rol un superusuario? (S / n) s
CREATE ROLE
proceed to create a database to experiment, in my case I will create the database mydb:

postgres @ machine: $ createdb mydb CREATE DATABASE


Once done
we return to the console of our user account by doing:

postgres @ machine: $ exit root @ machine: # exit
Luix @ machine: $

Then, we start postgres:

Luix @ machine: $ psql mydb


This command will show output like this:

Welcome to psql 8.2.3, the PostgreSQL interactive terminal.
Type: \\ copyright for distribution terms
\\ h for help with SQL commands
\\? Help psql commands \\ g or end with semicolon to execute a query
\\ q to quit mydb = #



Which tells us that we have entered into the database. At this point, we can execute all SQL commands we need.

As a last step, for security reasons, we can change the password of our user database.


mydb = # alter user Luix with password 'password';

ALTER ROLE
To exit the database do:


mydb = # \\ q

Finally, to connect from the console to the database you just created, whenever they need it, simply run the command:

Luix @ machine: $ psql-h localhost
mydb Password: password

That's all in the management of postgres from the console, now see the installation and operation of pgadmin.

2) Installing pgadmin


Luix @ machine: $ sudo apt-get install pgadmin3

The above command will allow us to install the packages: libpq4 pgadmin3-data pgadmin3
Well, now run the program just install:
Luix @ machine: $ pgadmin3 &

Once this is done, proceed to add a server for our program, following the menu:

File -> Add Server ...

Enter the requested information in the dialog presented:

Address: localhost Description: Connecting to localhost
maintenance BD: mydb
Username: Luix
Password: password


In 'Address' we enter the location of our database, in our case will be 'localhost' since we are working with a local database. In
'Description' preferably describe the connection to the server you are creating.

'BD-keeping' in this field enter the name of the database that we will manage.

'Username', for that, enter the user name and account created in the DBMS. 'Luix' in our example.
'Password', enter the password you assign the user name you have created. We

to 'accept'.

Then, we Double-click 'on the new connection is created and then observe something like this:





rescue the interface should be provided by pgadmin is very friendly, You can do everything from create a table to create more databases, based simply right click on the desired item in the left pane. For example, if we create a table we must right-click on the item 'Tables (n)' and then 'new table' (where n is the number of tables we have today), to fill the name and owner.

In short, it's just "exploring" some options and menus of the program, according to our needs, of course.

PD. Any errors or comments can do it THROUGH a comment or sending me an e-mail.

[HOW TO] How to create a local repository using the ISO's Ubuntu

Until recently I had at my disposal repositories
DVD's to install the packages needed GNU Linux distribution I'm using now Ubuntu 7.04 (Feisty). But sometimes it is very inconvenient to switch from one DVD to another when installing a particular package with their respective units. So I decided to copy the DVDs to my hard drive to make more dynamic the maintenance of my system.

The only drawback, perhaps, whether the space they can occupy the DVDs, which become 16 GB for the packages. Deb repository.

this little guide may also serve to those without Internet access (ie relatively slow) and need to install / update certain packages of the system and can also save the time it takes to switch from DVD to DVD when installing a package with many dependencies.

Here are the steps taken:

1) Burn the DVDs as ISO images on your hard disk.


is very convenient to copy each of the DVD's the repository for images, because for some reason-perhaps because of lack of disk space in the future, we want to delete the local repository and / or need to create new copies of itself in for DVD's, even to copy them to a friend of yours.


1.1. We enter the DVD into the appropriate drive and run:

$ dd if = / dev / dvd of = / home/usuario/ubuntu7.04/ubuntu_0.iso


This command creates the file "ubuntu_0.iso" (the first DVD) in the folder / home / user / ubuntu7.04 /. Repeat the process for each of the DVDs
Until this point we have the following files: ubuntu_0.iso
ubuntu_1.iso ubuntu_2.iso
ubuntu_3.iso

2) Create mount points.


we need to create folders in which we will mount the file later.


iso $ sudo mkdir-p / mnt/ubuntu7.04/CD0
$ sudo mkdir / $ sudo mnt/ubuntu7.04/CD1
mkdir / mnt/ubuntu7.04/CD2 $ sudo mkdir / mnt/ubuntu7.04/CD3

Done, we already have the folders list.

3) Mount the. Iso mount points enabled.


This step is easy, simply run:

$ sudo mount / home/usuario/ubuntu7.04/ubuntu_0.iso-r-t iso9660-o loop / $ sudo mount mnt/ubuntu7.04/CD0
/ home/usuario/ubuntu7.04/ubuntu_1.iso-r-t iso9660-o loop / mnt/ubuntu7.04/CD1
$ sudo mount / home/usuario/ubuntu7.04/ubuntu_2.iso-r-t iso9660 - o loop / mnt/ubuntu7.04/CD2 $ sudo mount / home/usuario/ubuntu7.04/ubuntu_3.iso-r-t iso9660-o loop / mnt/ubuntu7.04/CD3

Or if you prefer, you could copy the following script that will do all that for us, the proper name of the file could be
montar_repositorio


# / bin / bash set-x

mount / home/usuario/ubuntu7.04 / ubuntu_0.iso-r-t iso9660-o loop / mnt/ubuntu7.04/CD0 mount / home/usuario/ubuntu7.04/ubuntu_1.iso-r-t iso9660-o loop / mnt/ubuntu7.04/CD1
mount / home/usuario/ubuntu7.04/ubuntu_2.iso-r-t iso9660-o loop / mnt/ubuntu7.04/CD2 mount / home/usuario/ubuntu7.04/ubuntu_3.iso-r-t iso9660-o loop / exit
mnt/ubuntu7.04/CD3
then proceed to give you execute permissions:


$ Chmod + x montar_repositorio


Copy the file to the root folder of the executable.
montar_repositorio
$ sudo cp / sbin /

Ok, with that little script, each time you start our system, simply run the following command to get the repository enabled.

$ sudo montar_repositorio


4) Modify the sources.list


Now we have our repository enabled, you need to edit the file / etc / apt / sources.list to update our list of available packages.

$ sudo gedit / etc / apt / sources.list Open the file mentioned and then proceed to discuss with the # all lines are not (preferably) to avoid problems with the repositories enabled by default, you see, refer to a website particular.
Once this is done, include the following at the end of the file: # Repository

local hard disk
deb file: / mnt/ubuntu7.04/CD0 / feisty main restricted universe multiverse deb
file: / mnt/ubuntu7 .04/CD1 / feisty main restricted universe multiverse deb file: / mnt/ubuntu7.04/CD2 / feisty main restricted universe multiverse deb
file: / mnt/ubuntu7.04/CD3 / feisty main multiverse


restricted universe Save the changes and close the file.

5) Update the list of available packages.


Now that enabled the repository, and also made the necessary changes to our sources.list, is simply to update the list of available packages:

$ sudo apt-get update

And if possible, update the system packages:

$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade

see, not so difficult to create our local repository, we just need the files. iso of packages. deb version we need for our distro Ubuntu.
I hope this guide will be useful.

thousands of fires swept through Bolivia to

A tremendous amount of smoke that reached the city of Cochabamba

(where I live), so much so that some days ago and could not see the Cordillera del Tunari.
and browsing the net a bit, I found an amazing picture that sums up the bad time that was going on our territory, beset by several, not thousands of fires.

However, it was learned that despite the relief that the rain that was meant to quell some of the fires and clearing to some extent the smoke, were many sequels that give rise to widespread concern to some extent.

Among those we mention, are the material losses, people who were left homeless, which could be further noted that some of their animals died. No doubt a fairly critical for these people, many of whom were forced to evacuate the affected areas.

But now, who or who is responsible for such losses, irreparable damage to the national environment, as well as the lungs of our planet?, Questions that remain floating in the air ... At some point, hopefully, be answered. Apparently, it still a great lack of awareness for the preservation of our forests, our animals, plants, our environment in general. One issue that will undoubtedly much more to talk.

To finish this brief commentary, I recall a song from one of the most important rock bands in Latin America, spoke of Mana. The song is called "Where the children play?", Whose lyrics have much to do-in protest, with all the events that are changing our world: thousands of destroyed forests, air pollution, pollution of the oceans, in order. I hope this way of thinking.

A pretty funny video, not wasted.

In an unprecedented event for the industry label, rock band prepares to launch his new album

titled "In Rainbows" which is available on its website for downloading. What is new is that fans who wish to acquire such material, however incredible it may seem, are the ones who will ultimately decide the price they will pay for the album. Many are those who think they finally made it as an "experiment" for the band, but we are the artists who are finally in all the right to undertake the promotion of music they play.
To finish this post, I leave you with one of the singles which was a true global success, Yes exactly, I'm talking about Creep.
