Dive into the internals of profiling interpreted Python and Ruby code using eBPF

At the beginning of the year, I wrote a bunch of articles on the various tricks DOS played to overcome the tight memory limits of x86’s real mode. There was one question that came up and remained unanswered: what were the various “models” that the compilers…

Abstract interpreters are tools to compute approximations for behaviors of a program. These approximations can then be used for optimisation or for error detection. In this paper, we show how to describe an abstract interpreter using the type-theory based…

Undefined behavior (UB) in the C programming language is a regular source of heated discussions among programmers. On the one hand, UB can be important for compiler optimizations. On the other hand

In view of the addition of __VA_OPT__ first to C++ and now to C23, there had been interest in extending the C preprocessor to include recursion. The basic idea would be that __VA_OPT__ can be used …

The moment that spawned this article was when I asked myself how hard
can it be to make sure two types have the same size at compile time? Well…
it’s complicated. In here, we’ll do a deep dive into the limits of compile
time metaprogamming in today’s (and…
