Linux Fu: Shell Scripts in C, C++, and Others

At first glance, it might not seem to make sense to write shell scripts in C/C++. After all, the whole point to a shell script is to knock out something quick and dirty. However, there are cases where you might want to write a quick C program to do something …read more

Lambdas for C — Sort Of

A lot of programming languages these days feature lambda functions, or what I would be just as happy to call anonymous functions. Some people make a big deal out of these but the core idea is very simple. Sometimes you need a little snippet of code that you only need …read more

Add Scripting To Your C++ Programs With ChaiScript

If you are writing a program that has a technical user base, it is a nice touch to make the program scriptable. In fact, you might want to do the hard work in a programming language and then use your scripting language to build out features. In theory, this should …read more

The No-CPU Computer Gets A C Compiler

C is the most perfect language and it will run on anything. It will even run on a computer without a CPU.

The computer in question here is the Gigatron, a fully-functional ‘home computer’ the likes of which you would find in the late 70s and early 80s, complete with …read more

A Compiler in Plain Text Also Plays Music

As a layperson reading about some branches of mathematics, it often seems like mathematicians are just people who really like to create and solve puzzles. And, knowing that computer science shares a lot of its fundamentals with mathematics, we can assume that most computer scientists are also puzzle-solvers as well. This latest project from [tom7] shows off his puzzle creating and solving skills with a readable file which is also a paper, which is also a compiler for C programs, which can also play music.

[tom7] started off with the instruction set for the Intel 8086 processor. Of the instructions …read more

Nim Writes C Code — And More — For You

When we first heard Nim, we thought about the game. In this case, though, nim is a programming language. Sure, we need another programming language, right? But Nim is a bit different. It is not only cross-platform, but instead of targeting assembly language or machine code, it targets other languages. So a Nim program can wind up compiled by C or interpreted by JavaScript or even compiled by Objective C. On top of that, it generates very efficient code with — at least potentially — low overhead. Check out [Steve Kellock’s] quick introduction to the language.

The fact that it …read more

Demystifying The ESP8266 With A Series Of Tutorials

If your interest has been piqued by the inexpensive wireless-enabled goodness of the ESP8266 microcontroller, but you have been intimidated by the slightly Wild-West nature of the ecosystem that surrounds it, help is at hand. [Alexander] is creating a series of ESP8266 tutorials designed to demystify the component and lead even the most timid would-be developer to a successful first piece of code.

If you cast your mind back to 2014 when the ESP8266 first emerged, it caused great excitement but had almost no information surrounding it. You could buy it on a selection of modules, but there were no …read more
