Diagram of the time server from the stratum-0 to the stratum-3
Have asked yourself sometime if exists an universal reference clock?. In reality doesn't exists, because the time is relative, but a lot of computer applications, specially for the programs that make operations in the stock exchange or bank transactions, is needed have the clocks in the earth synchronized.

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.

Cover of the movie Matrix Reloaded
Following with the prior post, I'm going to expose some questions of the science that would be solved if we were in the Matrix. You will see that some of them are so rare and could be considered a glitch in the Matrix or a programming bug. Follow discovering "Glitches in the Matrix"

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.

Apocalipsis 2038
A lot of programs wrote in C, Unix operating systems and others based in this, use a date format that consist in count the seconds that have passed from the midnight of the January 1, 1960, without counting leap seconds. This format is called POSIX and when arrives the moment 19/01/2038 03:14:07, the counter will show incorrectly the date 1901/12/13 20:46:52, causing errors in a lot of programs.
