W. D. GANN'S

RECOMMENDED READING LIST

The following books come from W. D. Gann’s recommended reading list which was released to his students in 1946 as the fundamental background reading for any serious student of market forecasting. Many of these books are extremely rare, and we are proud to make available the largest selection of these books ever offered since Gann’s time. Many of these books have been out of print for half a century, and most are not available through any other source. We are currently reorganizing these selections into collections combining complete works of one author, or topically similar titles, to provide these essential resources as accessible prices. Check the Seeker's Sanctum for changing prices and availability.

Simple Programming Problems

Whenever I’m TA for a introductory CS class where students learn some programming language, I have trouble coming up with good exercises. Problems from Project Euler and the like are usually much too difficult for beginners, especially if they don’t have a strong background in mathematics.
