hpr1620 :: Passwords, Entropy, and Good Password Practices

Right now for most of us the key to any security in our online life is the degree of entropy in our passwords. So what is entropy, and how does it affect our passwords?

Entropy is in general the degree of randomness or disorder in any given system. Sometimes it is very easy to assess, such as a password of 1234, which all too many people use. Because it is a simple sequence, there is no real randomness at all, and would be quickly guessed. And as we saw in the last tutorial, such passwords are quickly discovered in a dictionary attack. There are things you can do to make it less likely that your password will be cracked and used against you. - For more go to http://www.zwilnik.com/?page_id=530

This show is about programming on a Raspberry Pi with on operating system or libraries. In this programming environment, the only software that the CPU executes is the software that you write. This episode introduces how to configure the build environment and get a basic application up and running. From here one can leverage these techniques to build more sophisticated applications and deepen ones knowledge of systems programming.

Here is some of the source material that I used while working on this little learning experience.

This show includes two interviews with OggCamp attendees this year.

The first interview is with TDTRS co-host Peter Cannon, who is convinced that his podcast is the best Linux podcast there is and he is sure going to tell you why.

In the second interview I talked to Alistair (whose name I hopefully spell correctly), who told me that he would like to be a HPR host himself. So this ist his first appearance on HPR and hopefully not the last.

If this show only confuses you, search the Internet for the Android app Spaceteam, have some friends install it and start playing. To maximize the fun you preferably play in a public place.

hpr1615 :: 39 - LibreOffice Calc - Inferential Statistics Functions

Inferential statistics is how we draw conclusions from data and make predictions.

Inferential statistics is what you do to say that something is likely, or that it is not due to chance, or things of the sort. It goes beyond simply describing what is in the numbers and lets you say something about what the numbers in a sample might mean for the population that generated the sample. There are several type of Inferential Statistics that I want to address in this tutorial, beginning with the idea of a confidence interval. - For more go to http://www.ahuka.com/?page_id=861
