Error accessing database OpenbravoPOS in Ubuntu
July 16th
It seems that new versions of OpenbravoPOS not just like Ubuntu. I have seen that if we try to start the program an error saying it could not find the driver database, whether we wanted to use MySQL or Derby.
The error that appears is the following:
Database Manager message
DNG_00_0000
Danger: Can not connect to database. Database driver not found.
com.openbravo.basic.BasicException:
Can not connect to database. Database driver not found.java.lang.ClassNotFoundException:

Ubuntu 10.4, Lucid Lynx is already among us
April 30th
I recommend using the download via the BitTorrent network , in contrast to the direct downloads faster as more people download it in 15-20 minutes you can have it. If you try a direct download servers you are probably saturated.
You have no excuse not to download the 700MB better invested in the season includes some new features as we discuss and simply encourage you to try it, it's as easy as downloading the ISO file, burn it to CD with any program that allows PC and start the system including Ubuntu LiveCD. If you like what you see then you can make a facility shared with your Windows system with few problems. Even you have an available install Ubuntu from a Windows utility called Wubi .
Is there a version for each PC, 32bits, 64bits, for servers and even a version for netbooks (small laptops).
You're taking too long to try it!

Tools to remove anti-virus programs
January 23rd
Neither have I gone mad or is a typo. While it may seem like nonsense, sometimes we have to remove a virus from your system. It may be several reasons, such as a malfunction of the same, a change of antivirus, reinstalling programs, etc..
Usually just use the uninstaller found in the list of programs or through the control panel. But at other times we may find that it is very difficult to remove a virus, either the typical errors in uninstaller, installation of more than one antivirus program that blocks the other, a system malfunction operating or because they simply will not appear on the list of programs to remove it. In such cases, should be aware of the existence of free utilities that serve to eliminate the virus from our system permanently and more or less safe, without modifying the system registry files or delete files manually.
In most cases they are the same antivirus companies that offer these tools, to support their users. One of the main advantages of these programs is that we can clean the whole system of registration of the virus that may reside in our system.
Just today I had to fight for a while because of a bad installation that I caused myself, ignoring the warning that with so much knowledge I had ESET NOD32 meanwhile wanted to install it and still there was another resident virus in the system. After a few tests, re-installations of programs and restarted the computer I had no choice but to entrust myself to one of these utilities.
Of all the utilities that I've been using Symantec's Norton have been (by far) and Panda (in their disputes with printers, Internet access ...). It is not strange for what reason, but it is quite common that some antivirus like Norton, give problems when trying to remove them from the system and force us to use these utilities.
I leave you with a list of tools to remove the virus;
- How to remove Norton - Norton removal tools - Norton removal tool (direct link)
- Remove Panda Antivirus Pro 2009 - Utilities to remove Panda, PandaSecurityUtility and uninstaller_09 (direct links)
- McAfee Cleanup , to remove McAfee anti-virus utility.
- Removal Tool for Kaspersky Lab products - Kaspersky Removal Tool "Klean" (direct link)
- How do I remove it manually ESET security product? - Eset uninstaller (direct link)
- Avira Support Downloads - Avira AntiVir Registry Cleaner (direct link)
- Install Avast Uninstall Utility - aswclear (direct link)
- Uninstall AVG - cleanup utility (direct link)
NOTE: Refer to the conditions and issues to consider for each tool, some need to run them under special conditions, such as in security mode (failsafe).
Some links and reference;
- How to Uninstall McAfee Security Center
- How to Remove Antivirus Panda
- How to solve problems that can occur in removing other antivirus (Panda)
- Uninstaller (removal tools) for common antivirus (Eset)
- AVG 9.x Uninstall / Re-Install Instructions
One fact is fun enough that many companies offer a page reference tools to remove programs from the competition and so how can hide their products.
I hope that this article no longer have more trouble installing Uninstall the antivirus rebels.
Linux video editing easy, thanks to OpenShot
January 18th
There are many programs to edit video, but not all are focused on a specific user. As we shall see OpenShot is a video editor that combines a number of features that its competitors lack.
Often, in the edition of our videos we have to consider three things;
- Power of our computer.
- Price video editing program.
- Complexity of the program.
Power: Obviously the first point is important, but any current mid-range computer meets the requirements without much effort. As for the processor (CPU) with an intellectual or a CD or C2D do AMD Athlon, 2GB of RAM (depending on OS), a video card if not integrated onboard the better and more hard drive can store more videos.
Price: One of the best professional video editing software is Adobe Premier, but not its 700 € cost make it suitable for everyone, Pinnacle Studio is more attractive with a very economical price (less than 100 €). Remember that Pinnacle offers everyone a free product called Videospin that although compliance with the above function has some limitations when exporting the video. Considering the price, look for a video editor free and also available for Linux.
Complexity: Please note that the more things we can do with a program is more complete, but also increases the difficulty. Often I hear people complain about the difficulty of Adobe Premier, when you simply should rethink what they do. What is the best video editor does not mean that it is the best solution for them. Often a simpler and less complex program will do what they need / want to do.
Given all this, look for a video editor that is free, easy to use and available for Linux. Jahshaka now CineFX platform and is free, but too complex for an average user, Kino is simpler, but I just do not convince, OpenShot, easy to use, free and available for Linux. There are many others, I always recommend trying out a few and stick with what you need to offer.
What can we do with this free video editing program (OpenShot)?
- Non-linear video editing.
- Transitions, video effects to image.
- Multi-track video and audio.
- Split screen to show more than one video at a time.
- Chroma key, to change a color to a video, that is, the typical green screen background that is used in special effects.
- Key frame animations.
- Export to various video formats (avi, mpeg) and codecs (DivX, XviD, H.264), among others.
The OpenShot includes an interface very similar to other video editors like Pinnacle Studio and is available in many languages. It is ideal for creating videos that we either send Internet services like YouTube or Vimeo.

Synthesia, a game to learn to play piano
December 30th
If you think you've seen everything in music simulators such as Guitar Hero series (and all other * Bands or Hero), Singstar, such as DDR and we can add another name Synthesia game with a difficult to pronounce and even more difficult to master. The purpose of the game is nothing less than playing the piano. And I do not mean to pretend that you play the piano but to play the piano, playing the piano:
By way of summary, we say that the game is free and does not require a very powerful computer. The mechanics of the game is simple, vertical bars are going down the screen into a virtual piano keyboard, so you have to press the corresponding key at the right time. We will obtain the best score according to our skills and practice.
You can download the game from the official website: www.synthesiagame.com
Source of version 0.62 is available on the SourceForge project page , from this version the game has become free but not free.
Although the "game" is only officially available for Windows and Mac OS are working with a conversion for Linux called Linthesia. Although the official website of the project still will not find much information, you can download a preview version from sourceforge.net / projects / linthesia
I took a month to "play" in a position with this game, and I think now I can comment on the same property and knowledge. To remove all the juice we need music in this game simulator;
- A computer with Windows or Mac OS. Although since recently there is also a version available for Linux.
- A keyboard or piano "e" to exit USB or MIDI in and out.
- Find the songs you want played.
- Buy the " Learning Pack . "
If we want we can do with just a PC and a conventional qwerty keyboard (with letters and numbers of lifetime). Not required to have a piano to play this game, but if you enjoy the music and the game ended up buying a piano. For less than 150 € (200 € maximum) can have a good Yamaha keyboard with 61 keys and MIDI connections. I have been testing a Yamaha PSR-E323 Entry-Level Portable Keyboard , which has no USB connection, but if MIDI input and output, then I bought a USB to MIDI adapter like this, EMU Xmidi 1 × 1 USB MIDI Interface (29 €) or such other USB MIDI Cable Converter PC to Music Keyboard for under 15 € and runs smoothly.
Some may find it expensive, but if we start to count euros invested in plastic guitars that do not serve as an instrument of truth and games that teach us anything, it may change your mind.
If someone asks if it is worth paying for improvements to the learning package, the answer is without a doubt YES. For these reasons:
- Contribute to maintaining the project, which involves new features for future versions. For less than 13 €!
- You'll get a set of tools that allow you to learn to play piano. Not only to play.
If you have any questions you can access the forum of the game , where you can find all information and assistance possible, even to find that song in MIDI the way we like.
Anecdotally, we note that this game was called Piano Hero, until the good people of Activision (Guitar Hero poseidors) you were required to ask the creator to change the name because it was too similar to the game their property ... The Wikipedia is a source of information!
On youtube and you will find many similar channels and video dedicated to the game , I would highlight each of HDPiano.com you will find lessons to learn to play piano with the help of Synthesia.

The list of the 5 major free applications for home users
December 1st
Top ten lists and the like are a quick and easy way to show the "best" applications, often with news on over there for all tastes, and sold a few days ago it echoed in Noticias3D ( MuyLinux - SmashingApps ) with 15 large open source software projects.
I also encourages me to do it, but with a difference, create different lists of applications for each sector of users. I begin by the end user, for those who want to use a computer without being a hacker or have a university degree in telecommunications and computer engineers.
This list of open source software (open source) will consider most important the following criteria;
- Programs that can be used by any person regardless of their knowledge.
- Son of daily use applications, which cover the tasks that we perform at any time before a computer.
- All applications will be free and available free for various platforms (Windows, Linux, Mac).
- In almost all cases are also available in Catalan.
The list of the 5 most important applications for home users is this;
- GNU / Linux , with distributions such as Ubuntu , Debian ... I think that today, anyone can use a Linux distribution without many problems. Maybe the installation of the system is a separate issue, but if you know to install Windows you'll have no problem with Linux. And you can always try it with a LiveCD .
- OpenOffice , the free office suite's most important moment will find everything you need to create text documents, spreadsheets, presentations, diagrams ... And the most useful tools such as spell check in almost all languages and compatibility with other similar programs such as Microsoft Office (Word, Excel and Powerpoint).
- Mozilla Firefox , one of the best web browsers of the time. The points in favor, reliability and the large number of extensions that can add, such as to avoid the publicity of many websites.
- 7-zip , compression of files with one of the best levels of compression and supports many popular formats such as zip or rar.
- VLC Media Player , media player perfect for videos and DVDs.
Find an application that is missing? Do not you agree with the list?
Later I will create another list with a total of 10 free applications for home users and other more specific lists.
