Environment: DOS/Unix console These days, programmers generally develop using some GUI IDE; however, it may happen that one is given only traditional command-line tools. In this case, using the classic program “make” to generate/update a program, especially when source code is spread across many unit files, may be a solution. I will briefly show where […]

Prime numbers have important applications in mathematics and computer programming. I met a mathematician on a return trip from Montreal, Canada on his way to a mathematical society meeting in the “Big Easy”. Having studied mathematics a bit (and realizing I could work for 35 years and never publish a new theorem), I asked him […]

Environment: .NET Introduction Object pooling and caching are very useful object-orented patterns. They work well for large or hardweight objects. For example, you can store GDI+ pens in some PenStore, which stores its pens in maintained cache. This pattern greatly improves the speed of your code without adding to the object heap’s overhead. How to […]

I used to be very concerned about this performance cost as well, but having written, built, and used many managed assemblies for several years now, […]
