Implementing Portable Threads and Mutexes
Implementing a portable framework for multi-threading doesn’t have to be difficult or error prone. With the right framework, implementing multi-threaded programs can be pretty simple, and you can hide all the platform dependent functions. You can also implement your threading…
Generating 64-bit Random Numbers in a Given Range
There are good standard ways of generating 32-bit random numbers. If you need something really simple, it is possible for example to generate decent random numbers with a Linear Congruential Random Number Generator:
Using BerkeleyDB to Store Serialized Objects in C++
I’ve been working on a C++ interface to Berkeley DB to support some ongoing projects. The goal is to create an interface that allows me to store serialized C++ objects in a database. Each object is flattened into a text…
