Efficient C++: Performance Programming Techniques by Dov Bulka
Bulka and Mayhew's "Efficient C++" is an enjoyable and useful book, filled with helpful information that can be immediately applied to C++ programming. Its coverage of techniques for inlining, achieving the return value optimization, and avoiding temporary object creation is quite good. I also found the second chapter, which presents a case study about writing a tracer class, to be informative and a tidy overview of efficiency methods. There are also chapters discussing virtual functions, memory pooling, STL, and efficiency at the implementation and design levels. One helpful feature of this book is its presentation of a number of bar graphs illustrating the runtimes of actual… Read more
Vol. 3: The Subliminal Verses ~ Slipknot
There are three big problems with this album. First, all the aggressiveness and heaviness has been produced out of the guitar sound. Second, the drums are so quiet they might as well not be there. Third, Slipknot has forgotten how to write interesting songs.
I loved Slipknot's first two albums. I was impressed by the overall aggressiveness, percussiveness, and brutality of those albums. I was also impressed by the range of vocal styles and the incorporation of a variety of percussion sounds and scratching into loud, heavy music. Almost all the songs on those albums are catchy and make want to bang your head, if not beat the crap out of someone.
This album, however, has lost… Read more
Introduction to Perturbation Methods by Mark H. Holmes
I have read several books on perturbation methods, and this book absolutely the best. Perturbation methods are used in problems where the equations (algebraic, ODEs, or PDEs) involve a small parameter, or that evolve on multiple time scales that differ by orders of magnitude. The basic idea is to build an approximate solution to the equation based on a series expansion involving the small parameter. Usually two or more series expansions are built and then combined to yield a solution to the equation that incorporates dynamics on both the slow and fast time scales (for example).
The first two chapters introduce the basic concepts of asymptotic expansions. Several informative, though… Read more
