Comment What is Mathematics? by Courant and Robbins (Score 1) 467

The book "What is Mathematics?" by Courant and Robbins, despite its cushy-sounding name, would be my recommendation. First of all, it's written by two world-class mathematicians. Second, it's not a textbook; rather, it's what you might call a celebration of how awesome math is. If you want to succeed in college math without being miserable, why not try to see the subject as thing of beauty, rather than a burden? This book will definitely help you do that. If you read through the first half of the book (it shouldn't take long) you will have a chance to warm the math parts of your brain back up, and you'll learn some extremely cool shit along the way. (A bit of geometry, a bit of topology, a bit of algebra, etc.)

When you get to the authors' lucid explanation of the main ideas behind calculus, you'll realize that (1) calculus isn't scary, (2) the computations you need to learn how to do are fun, not hard, and (3) everything comes down to a few very intuitive ideas -- it may have taken geniuses like Newton and Leibnitz to come up with them in the first place, but they are part of our common intellectual heritage, not erudite ideas reserved for mathematicians and physicists.

And, although it's not a textbook, there are some exercises which will give you the chance to test your understanding. Again, though, they are fun, not grueling.

However, in this case the *stepfather* left a gun around that killed a child that wasn't his. He may or may not be suffering, and it should be investigated.

Read the article. Normally the gun was kept in a locked place away from reach by the children. He took the gun out because he thought he heard an intruder. After investigating, he let the gun on the table and didn't put it away immediately.

An experienced java programmer could manage to create memory leaks using threads but you almost have to do this on purpose ;-))

Wrong. You an have memory leaks in Java just as well. It's just more difficult.

I'd even go as far to say that experienced people are more likely to cause a Java memory leak, because they'll be doing unusual things for optimizing/caching and what not.

Usually, this involves Swing and dialogs that were closed and forgotten about, and not properly dereferenced.

Crazy Firewall Log Activity — What Does It Mean? 344

arkowitz writes "I happened to have access to five days worth of firewall logs from a US state government agency. I wrote a parser to grab unique IPs out, and sent several million of them to a company called Quova, who gave me back full location info on every 40th one. I then used Green Phosphor's Glasshouse visualization tool to have a look at the count of inbound packets, grouped by country of origin and hour. And it's freaking crazy looking. So I made the video of it and I'm asking the Slashdot community: What the heck is going on?"
