A close relative of mine teaches Maths to school students in different Grades. During a casual chat some time ago, he mentioned that he was trying to adopt an automated approach to selecting assignment problems based on each student’s performance so far. Obviously, there are many ways in which this can be done, but he […]
When you program in Rust, especially in a non-trivial project, there is a good chance that you will need to call “external” functions (usually, C/C++) that are available in a DLL (we are talking about the Windows platform here). It could be because you wish to re-use some code that you have earlier written in […]
A few days ago, I purchased Xojo Pro commercial license. In case you haven’t heard about the product, Xojo is a popular cross-platform development tool targeting Desktop, Web and iOS (Android is expected in the near future). It supports an Object-Oriented Basic language. It has been around for over 25 years and has been steadily gaining […]
Traits in Rust are an amazing feature and contribute significantly to the expressive power of the language. For someone coming to Rust with a C++ background (like me), Traits appear to be quite similar to Abstract Classes in C++. Although they are similar, Traits have certain characteristics that set them apart. In this article, I […]
Title: Introducing Blockchain with Lisp: Implement and Extend Blockchains with the Racket Language Author: Boro Sitnikovski Publisher: Apress Year: 2021 Blockchains are a hot topic these days and interestingly, I am getting involved in a project that uses Blockchain. Languages such as C++, Java, Go and Node.js are commonly used in such projects, so when […]
Languages such as C/C++ and Java follow an “eager” argument evaluation approach, where function arguments are evaluated before the function is entered. Of course, there are idioms and tricks that one can use to force “lazy” evaluation. The primary benefit of “lazy” parameter evaluation is that the parameter is evaluated only when it is used and […]
In the last article, I briefly explained how D language has built-in support for performing unit tests. I feel this is an advantage over many current languages. What if we want to run only a subset of unit tests? Although it is a good idea to run the unit tests every time there is a […]
While I admire D language for many of its elegant and powerful features, two features stand out in my opinion. These are support for Design by Contract (DBC) and Unit Testing. I am a great fan of DBC and will cover that feature in a future article. Today I let me briefly touch upon D‘s […]
When I heard the name Mixin for the first time in the context of Dlang, I imagined it would be something similar to the mixins of Common Lisp, but I was completely wrong! Mixins are a very interesting feature of D language. They allow code to be “injected” into the source at “compile-time” and hence facilitate “meta […]
One of the many “cool’ features of Dlang is “Universal Funcion Call Syntax”, which permits non-member functions to be invoked using the member function call syntax. When you add to this the fact that this applies not just to user-defined types but to primitive types as well, things get interesting. Let us look at some […]
