A clarification of evil

Earlier I wrote in The Sun Download Manager is evil a subsequent generalization, and I wanted to make a clarification. I stand my by title, but not that the entire company is evil. Perhaps are 1am and being tired, and rather peeved I could not download the free software with any ease I needed to as they say “sleep on it”.

Let me further detail why the Sun download manager is simply to never to be used without due consideration. You first have no choice, if you use the Sun Download Manager to download software (I’ll have to review if you even have an option not to use it), you must accept the SSL trust requirement, to not accept is to not use the download manager, so straight away you have no option (this is the path to being evil). When you accept the trust of the download manager, you are signing over your entire computer to the software to which you don’t know what it’s really going to do. This is in essence how a Trojan horse works. This is how software from other sources can deceive people, even destroy all information on your computer. Combined with the fact that the download manager does a really stupid thing and places files in the ‘root’ directory of your machine is also something you should never allow and never do.

I really want to bring this to the attention of people, because I have plenty of friends and family which don’t understand computers as much, and what’s possible, and if say the trusted a Java Applet from Sun, they might just do this next time with a program who’s intent is to destroy, damage or transmit information on your computer.

This leads to the real justification of virtualization and always doing any web surfing or use in a dedicated virtual environment, however until this becomes simpler for the end user it’s not easy to configure and explain to a less experienced user.

Producing Skewness statistics with SQL

Skewness measures the asymmetry of a distribution. A perfectly symmetric distribution has a skewness of zero. A positive skew (right-skewed) means the tail extends to the right — a small number of high values pull the mean above the median.

Producing Chi-Squared statistics with SQL

The Chi-Squared test is one of the most widely used statistical tests for categorical data. It comes in two flavors: the goodness-of-fit test asks whether an observed frequency distribution matches an expected one, while the test of independence asks whether two categorical variables are associated with each other.
