Quantitative Financial Risk Management

Quant finance and risk sites worth checking out:

• Northstar Risk Corp.:
  My firm, and in my opinion the best third-party risk management software for the hedge fund industry. Also home to a small but growing collection of risk research papers.
  
  
• GARP.org:
  The Global Association of Risk Professionals. The largest, most recognized risk association there is and sponsor of the Financial Risk Manager (FRM) exam.
  
  
• Wilmott.com:
  Probably the most popular and comprehensive website dedicated to quantitative finance. The forums are a great place to search for answers to questions. If you can't find what you're looking for, ask nicely and somebody will likely answer your question before too long.
  
  
• NuclearPhynance.com :
  Another great quantitative finance site with great forums and a dedicated following.
  
  
• SYMMYS :
  SYMMYS is devoted to quantitative risk and portfolio management. SYMMYS was founded by Attilio Meucci. He has published some great papers (well written, innovative, and extremely relevant). He is also a great presenter. I have heard only good things about the quant bootcamp.
  
  

Web site design tools:

• Kompozer:
  The site was primarily designed using KompoZer, a good wysiwyg web authoring tool. The application is still a work in progress, but the price is right (free).
  
  
  
• FatCow:
  This site is hosted by FatCow. Cool name, good tech support, no complaints.
