The solution to this problem is being implanted, approximately from the year 2000 and will follow implanting during a lot of years more. This consists in replace all the software and hardware that use the IPv4 protocol to another that use the IPv6 protocol.

Phosphorus of a CRT screen
The screensavers, theoretically, serve to protect the monitors from the deterioration of the quality of the screen produced when you leave an image fixed during a lot of time. With the abandon of the CRT monitors in favor of the TFT-LCD, the screensavers leave of be useful, but a lot of people follow believing that still serve to save the screen.

Surely that a lot of times you have found webs impossible of be read, due to the color combinations used.
For that reason I've programmed a script that can transform any webpage making it more accessible. If you drag and drop this link to the bookmarks or favorite bar of your browser, and you click on it, when you find a web with colors that doesn't allow read it clearly, the web will change their color with the colors of Computable minds and the accesibility will be better in the majority of cases. If you want that the script will be executed always in all the webs, you can install it, having activated the Firefox extension Grease monkey, or using Chrome, and clicking in this link. Surprise yourself with the rest of "How to see better the web pages and improve its accessibility?"

Today I'm going to dedicate the post to explain some basic concepts about the files that the 99% of the people that use a computer don't understand it very well.
Some users know that the last letters that there are at the end of a file (the extension), identifies the type of file, so, for instance, an archive ended in .JPG is a type of file of image and another ended in .GIF is a different image format with other characteristics. This, is true for most cases, but causes confusion in the cases where the extension isn't of a concrete format, unless of a format container. Read all about of "Differences between extension and format in a file"

WiFi logo with bones behind
Neither me nor anyone knows if the radiations of WiFi networks and mobiles are bad to the health. There are an infinity of scientific studies about the effects of the electromagnetic non-ionizing radiations in the health, the fifty percent says that there are not evidences that prove that exists adverse effects, and the other fifty percent assert that there are. Read all about of "Are WiFi Networks healthy? (II)"
