This... definitely this. You generally cannot test your own work. You have too many assumption about how it works.

What developers SHOULD do is unit testing. One way to make this more bearable is to "code to the test". First create the unit tests which will prove your code does what it is supposed to.. then code until the tests pass. It's more like a game this way.

Go get Algorithms in Java and implement the algorithms. Not only will you learn about algorithms but simple tasks like this teach you a lot about coding that you can't learn from a book. That would be things like testing, and debugging.

Next implement something!
Good beginner projects are conway's game of life.
Tetris or breakout.

You can also go to one of the programming challenge websites and start working through their problems.

Then you really need to find a project that you want to implement. If not that at least an open source project that you can contribute to.

Comment Statistics may or may not = math (Score 1) 572

Statistics in it's purest sense is simply math. Very few people know very much about this.

Statistics in the wild is generally bullshit! You should not be able to get two equally qualified people the same data set and receive two different answers!

As for statistics for performance measurement? If you are doing something important than analyze worst case performance. Statistics doesn't come into play in this case.

The issue is more like this.
If you don't know what a splay tree is you will never know when to use one. It's a problem of not knowing what you don't know. It is very rare that you will need a datastructure and then go find one. You will use the tools you have to solve the problems in front of you.


Researchers Take Down a Spam Botnet 207

The Register is reporting on the takedown of a botnet once responsible for 1/3 of the world's spam. The deed was done by researchers from the security firm FireEye, who detailed the action in a series of blog posts. PC World's coverage estimates that lately the botnet has accounted for 4% of spam. From the Register: "After carefully analyzing the machinations of the massive botnet, alternately known as Mega-D and Ozdok, the FireEye employees last week launched a coordinated blitz on dozens of its command and control channels. ... Almost immediately, the spam stopped, according to M86 Security blog. ... The body blow is good news to ISPs that are forced to choke on the torrent of spam sent out by the pesky botnet. But because many email servers already deployed blacklists that filtered emails sent from IP addresses known to be used by Ozdok, end users may not notice much of a change. ... With [the] head chopped off of Ozdok, more than 264,000 IP addresses were found reporting to sinkholes under FireEye's control..."
