Where to find a job online?
June 14th
Throughout our working lives, and especially considering the current situation, one of the many tasks that we perform every day are 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 sites where you can find information and other related tools.
Needless to say, we can not ignore other in our research as visit companies to deliver our curriculum in hand, searching for deals on the press, known ... Internet gives us the ability to access at a time many offers, but we can reject as easily.
Before starting the process to update our curriculum and whenever necessary to create a personalized letter for each job. After we find what is our motivation, what we do, we would like to work, what are our expectations and then send us a question: have the training and / or experience required for the job that interests us ? From the moment we have only to decide which is our area of activity, municipality, county or area of activity where we work.
The process for finding a job through the Internet can be summarized in these steps;
- Access to the page with the job.
- Search the offers that may interest you, there will be time to discard it later.
- Register on our site, we ask for personal information, as well as introduce our resume.
- Inscriure'ns the job you want. At this point the company receives our interest in the job offer and start the selection process.
- Wait for a response, usually via the website, but they can also contact us via email or phone, especially if you think our profile right. It may take hours or days, so be patient. Most entries end at this time.
- If our bid is chosen company will contact us, we probably ask for more information or a personal interview.
HP buying 3Com
April 30th
HP once again shows 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 break 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 are not talking about anything new in the world of software we have seen Google buy anything that puts him ahead, but other companies like Adobe and Microsoft will not fall short.
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!

A netbook the company?
January 25th
Set 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 an ideal tool for business and people need to move constantly, entrepreneurs, freelancers and employees in general in many professions.
If you want to buy a netbook must ask ourselves a series of questions as necessary to make use of it:
- I really need a laptop? I go with a cell phone, blackberry or a PDA (PDA)?
- How many hours at work I can not connect the computer?
- I 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 laptop with these characteristics? The advantages of a netbook:
- Attractive price, cheaper than a laptop-sized "normal" (around 300 €).
- Better mobility, less weight (maximum 1-2 kg), occupies less space. Easy to transport.
- We have almost all the capabilities of any conventional computer, Internet, spreadsheets, PDF documents, system environment Windows (or Linux) are compatible with any program.
- The duration of the battery can work part time (4h), and in some models almost reach the 8-10am.
Disadvantages of a netbook:
- Low power, some applications may not work or go too slow, such as application design, CAD, 3D ...
- Limited functions, but today is not a big problem not having CD-DVD when there are USB sticks 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. You 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 more clear about what you can and what you can do with a mini-laptop.
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.
Create an inner shadow effect with Gimp
January 22nd
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 to 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. You will be 4 minutes thinking about the font you want to use.
Creation process;
- Create the image with the desired size: menu File -> New (CTRL + N)
- Color black and white text.
- Add text to a size considerably if we see the effect better with a font that is sufficiently thick, or with bold style.
- Duplicate the layer with the text.
- Create a new transparent layer (using the image size) over the duplicate text.
- Right on the transparent layer and choose Merge Down.
- Select the text with the color selection tool, and cut the selected part.
- Right click and select Menu -> invert (CTRL + I), fill the new selection with black (CTRL + O).
- Discard the selection, that is, remove all selections.
- Duplicate the layer with black text inverted.
- Select the original layer with the text upside down, right, filters -> blur / blur -> Gaussian
- Depending on the size of the text we can more or less value, the higher the gradient reaches farther.
- And we have our text with a perforated shade inside.
NOTE: Remember to save the file format *. xcf to maintain layers and properties of each element separately. You can then save a copy in the format that you feel (jpg, gif ...).
I created a video (screencast) with the entire process of creating this effect;
