July 16th

Posted by Hande in software

It seems that new versions of OpenbravoPOS not just like Ubuntu. I could see that if we try to start the program an error saying the driver could not find the database, regardless of whether I 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:

Throughout our working lives, and especially considering the current situation, one of the many tasks that we perform daily is looking for work, and one of the means or channels that might be faster is through Internet, although we will focus on specialized portals sector also leave a list of other pages where you can find information and other related tools.

Needless to say, we can not leave out other means in our research as visiting companies to deliver our curriculum in hand, the research offers the press, known ... Internet gives us the ability to access at a time many offers, but we can reject with equal ease.

Before starting the process to update our curriculum whenever necessary and create a personalized letter for each job. After we find what is our motivation, what we do, we like to work, what are our expectations and then asked us a question: have the training and / or experience required for the job that interests us ? From this moment we have only to decide what our area of ​​activity; municipality, county or area of ​​performance where we work.

The process for finding a job through the Internet can be summarized in these steps;

  1. Access the page with the job.
  2. Find offers that may interest you, there will be time to discard later.
  3. Register on our site, we ask for personal information, as well as introduce our resume.
  4. Inscriure'ns the job you want. At this point the company receives our interest in the job offer and start the selection process.
  5. Wait for an answer, it's usually through the website, but they can also contact us via email or phone, especially if it seems appropriate to our profile. It may take hours or days, so be patient. Most entries end at this time.
  6. If our bid is chosen company will contact us, we probably ask for more information or interview.

HP once again demonstrates again that does not stop growing as a large corporation wants to do everything and have everything. Basically what it does is buy other companies with complementary products that give value to your brand and help to get into markets that had not fully exploited.

3Com has cost 7200 million dollars (USD), nothing to do with the 25,000 million that was paid by Compaq for some years now.

We're not talking about anything new in the world of software as we saw Google purchase anything that puts him ahead, but other companies like Adobe or Microsoft will not fall short.

I strongly 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, is as easy as downloading the ISO, burn it to CD with any program that allows PC and start with the system including Ubuntu LiveCD. Then see if you like you can 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).

Already taking too long to try it!

Define as anyone netbook laptop that is small in size, as might be less than 12 "(inches), not differentiate between netbooks and ultra-portable.

A computer of this kind is a perfect tool for business and people need to move constantly, entrepreneurs, freelancers and employees in general of many professional sectors.

If you want to buy a netbook must ask ourselves a series of questions that need to be made ​​by use of the same:

  • I really need a laptop? I go with a cell phone, blackberry or a PDA (PDA)?
  • How many consecutive hours of work I can not connect the computer?
  • Need Internet at any time? Where will I work has a connection? There will be wireless available? I need a mobile Internet access?
  • I work with the tools and programs I need?

What gives us a kind of laptop? The advantages of a netbook:

  • Attractive price, cheaper than a laptop size "normal" (around 300 €).
  • Better mobility, less weight (maximum 1-2kg), takes up less space. Easy to carry.
  • We have almost all the capabilities of any conventional computer, Internet, spreadsheets, PDF documents, system environment Windows (or Linux) and compatible with any program.
  • The battery life lets you work part time (4h), and in some models almost reach the 8-10h.

Drawbacks of a netbook:

  • Little power, some applications may not work or go too slow, applications such as design, CAD, 3D ...
  • Limited functions, but today not a great inconvenience not to have CD-DVD having usb-stick and external hard drives.
  • Small screen, you have to work many hours can tire the eye.
  • Reduced keyboard, although this aspect has improved lately.

Some of the utilities and functions that can be found in most netbooks:

  • We can use them for live performances of a product or service of our company through the screen, or even connecting to an external screen or video projector. Some models include a touch screen, are called Tablet PCs.
  • Allows access to the Internet through any wireless network (wireless / wifi) that is available. We can also purchase a USB modem with a card of any mobile telecommunications company.
  • We can synchronize contacts, calendar and media files with other devices via Bluetooth adapters.

I hope this article will be clearer what can and what you can do with a mini-laptop.

Utilities to remove antivirus programs

January 23rd

Posted by Hande in service

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, installations of more than one antivirus program that blocks the other, a system malfunction operating or because they simply do not appear in the list of programs to remove it. In these cases, you should be aware of the existence of free utilities that serve to eliminate the virus from our system more or less permanently and safely, without modifying the system registry files or delete files manually.

In most cases are the same antivirus companies that offer these utilities, in order to support their users. One of the main advantages of these programs is that we can clean the whole system of record that the virus can 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, so that knowledge, I had NOD32 meanwhile wanted to install it and still there was another resident virus in the system. After a couple of 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 used most were the Symantec Norton (by far) and Panda (in their disputes with printers, Internet access ...). Not for what strange reason, but it is quite common that some antivirus such as 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 from ESET security product? - Eset uninstaller (direct link)
  • Avira Support Downloads - Avira AntiVir Registry Cleaner (direct link)
  • Utility to uninstall Avast - aswclear (direct link)
  • Uninstall AVG - cleanup utility (direct link)

NOTE: See the terms and aspects 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 Panda antivirus
  • 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

Something is funny enough that many companies offer a page where you refer to the tools to remove hidden programs in competition and so how can their products.

I hope this article do not have more problems to uninstall the antivirus rebels.

This effect is very easy to create and believe that results obtained from a sufficiently attractive, the program will work with Gimp, remember that it is free and available for almost all systems (Windows, Linux and MacOS). Following this guide get a text that has a white shade above, as if bored.

Difficulty: Basic / easy. If you can click the right mouse button you can follow this tutorial.

Time Required: Less than 5 minutes. 4 minutes you'll be thinking about the font you want to use.

Creation process;

  1. Create the image with the desired size: File menu -> New (CTRL + N)
  2. Color black and white text.
  3. Add text to a size considerably if we see the effect better with a font that is sufficiently thick, or with bold style.
  4. Duplicate the layer with the text.
  5. Create a new transparent layer (using the image size) over the duplicate text.
  6. Right click on the transparent layer and select Merge Down.
  7. Select the text with the color selection tool, and cut the selected part.
  8. Right click and select menu -> invert (CTRL + I), fill the new selection with black (CTRL + O).
  9. Discard the selection, that is, remove all selections.
  10. Duplicate the layer with black text inverted.
  11. Select the original layer with the text upside down, right, filter -> blurring / Blur -> Gaussian
  12. Depending on the size of the text we can more or less value, the higher the gradient reaches farther.
  13. And we have our text with a perforated shade inside.

NOTE: Remember to save the file in *. Xcf to maintain layers and properties of each element separately. You can then save a copy in the format that you feel (jpg, png ...).

I created a video (screencast) with the entire process of creating this effect;
