Online Learning: A Bachelor's Level Computer Science Program Curriculum Introduction [Update: See also the follow-up post to this piece, An Intensive Bachelor's Level Computer Science Curriculum Program.] A few months back we took an in-depth look at MIT’s free online Introduction to Computer Science course, and laid out a self-study time table to complete the class within four months, along with a companion post providing learning benchmarks to chart your progress. In the present article, I'll step back and take a much more broad look at com-sci course offerings available for free on the internet, in order to answer a deceptively straightforward question: is it possible to complete the equivalent of a college bachelor’s degree in computer science through college and university courses that are freely available online? The former question is more difficult to answer than it may at first appear. Yet, this does not mean that all the necessary elements for such a curriculum are not freely accessible. Our hypothetical curriculum will simplify this model.

Hacker Fundamentals: The Everyman's Guide to How Network Packets Are Routed Across the Web Hacker Fundamentals: The Everyman's Guide to How Network Packets Are Routed Across the Web In general, hacking and information security is not just one discipline, but a number of them, and today we will look into some of the networking concepts. In the last Hacker Fundamentals, we talked about the OSI model as well as a little on TCP/IP and the protocols that make up the suite. We already covered how your data travels the OSI model, layer by layer, and talks with other machines on your local network. Much of the 'talking' on a local network are broadcasts. No routers were hurt in the writing of this article. A Tale of Two Packets: Internal If you remember correctly, an IP address has two components, the network section and the host section. Let's say you wanted to send data to another computer on your local network at home. The first thing that gets done is the computer looks at the address on the packet being sent.

The Elephant in the Universe: Dark Energy – One Minute Astronomer In our brief look at dark matter, you found more than 80% of the matter in the universe is a type of particle or particles that emit no light, interact very weakly with matter in our everyday world, yet exert profound gravitational influence on the rotation of galaxies and the movement of galaxy clusters. Although particle physicists have a few good ideas, no one knows for sure what this dark matter might be, which is a little unsettling. But it gets even stranger because astronomers have since discovered most of the universe is made not of matter but a strange and unidentified type of energy– “dark energy”– that accelerates the expansion of the universe and may one day carry distant galaxies forever out of view. It all started with an attempt to weigh the universe. In the late 1980s and into the 1990s, two teams of astronomers, one led by Saul Perlmutter and another by Brian P. Type Ia supernovae have been observed for decades. A supernova in a galaxy far, far away.
