Some sanity for C and C++ development on Windows
A hard reality of C and C++ software development on Windows is that there has never been a good, native C or C++ standard library implementation for the platform. A standard library should abstract over the underlying host facilities in order to ease portable software development. On Windows, C and C++ is so poorly…

How to Build an Escrow Product
Escrow is a payment setup where the payer sends funds to a third party rather than directly to the payee. If certain conditions are met, the third party routes the funds to the recipient; if not, the funds get returned to the sender. Escrow is particularly useful for high value payments because the payer can rely on…

What Java Modules Are About
When the subject of Java modules comes up in online discussions every so often, I get the sense that many people misunderstand what it is that modules are supposed to do. That's understandable, as the name 'modules' does not evoke the precise purpose of the feature. There are many kinds of modules, even in the Java…

Mea culpa: How developers fix their own simple bugs differently from other devs
This paper from Zhu and Godfrey looks at single-statement bug fixes in Java code: more specifically, at the differences between how bug are fixed by the people who created them and how they are fixed by other people. The authors found that people fix their own bugs more quickly than other people's, which falls under…

In C++, is empty() faster than comparing the size with zero?
Most C++ programmers rely on "STL" for their data structures. The most popular data structure is probably vector, which is just a dynamic array. The set and the map are other useful ones. The STL data structures are a minimalist design. You have relatively few methods. All of them allow you to compute the size ……

A Bestiary of Functions for Systems Designers
Whether your game surfaces its numbers to the player or not, odds are it has underlying systems that rely on them, and you use functions to determine how those numbers affect each other. In other words, a mathematical function is usually at the core of the answer to a bunch of frequent game design questions.
