  1. Financial Mathematics Resources on My Life as a Quant · · Score: 1

    The canonical text is Options, Futures, & Other Derivatives, by John C. Hull (I have the 4th edition). It's an excellent introduction to standard pricing models for options and simple interest rate derivatives. If you're interested in the mathematical underpinnings, I highly recommend Financial Calculus by Baxter & Rennie. It's concise but densely packed, and the principles are universal.

    If you want some web resources, try:

    1. A solid collection of credit derivative resources.
    2. An excellent overview of financial products.

    If you find the field interesting, lucrative jobs are available in derivatives technology and quantitative analysis at hedge funds and investment banks. The biggest cities for this work (in the English-speaking world) are New York, London and Chicago.

  2. Re:Out of curiousity on Writing Code for Spacecraft · · Score: 4, Informative

    Feature size. The smaller the feature (think gate level), the higher the chance it will be ruined by random radiation exposure. And that's the one-sentence summary of the "Radiation Effects on Microelectronics" class I took about 7 years ago.

    Smaller memory capacity for a given surface area implies larger feature size.

    By the way, the class I took was 1-on-1 with Prof. Stephen McGuire at Cornell. Extremely cool guy.

  3. Thank You, Industry Apologist on TiVo to Sell Your Fast-Forward Button · · Score: 1

    The "fixed block of advertising is the lifeblood of content providers" line is getting old. For decades, product placement WITHIN content has been gaining ground. Have you seen a $100 MM+ movie lately? The Mini and Dorritos ads are quite visible, but not irrating enough to repulse viewers.

    The future holds two options: pay-per-view on-demand content, and free content with integrated product placement.

  4. Try Mandarax Open Source Rule Engine on Jess in Action · · Score: 2, Informative

    My favorite is Mandarax. It's a Java-based backward chaining rule engine with excellent documentation. I've found it to be fast and extensible. And even better, it's LGPL!

  5. Why YOU Don't Get Cell Phone Spam on Protect Your Cell Phone From Spam · · Score: 2, Informative

    Have you ever wondered why you don't get calls from telephone solicitors on your cell phone? People in Europe certainly do. Why are Americans exempt?

    The answer is a simple but important legal decision: it's illegal for solicitors to bother you if YOU must pay for the call. In Europe, incoming cell calls are free, but in the U.S. you pay a per-minute charge for the privilege of answering calls.

    Text messaging spam will be illegal only if it costs the victim money. Unfortunately, providers are moving to flat monthly rates for text messaging services. I expect this will become a burgeoning spam market.

    Sincerely,
    Brock Arnason
