Internals of Go's new fuzzing system
Go 1.18 is coming out soon. It's a huge release, but native fuzzing has a special place in my heart. Not much has been written yet on how Go's fuzzing system actually works, so I'll talk a bit about that here.

How Clang Compiles a Function
Minor nit: printing the predecessors of a basic block is a feature of the IL printer, not Clang. It is just visualizing information that is implicit in the IR anyway.

Elliptical Python Programming
One thing I love about Python is how it comes with its very own built-in zen. In moments of tribulations, when I am wrestling with crooked code and tangled thoughts, I often find solace in its timeless wisdom. Here's a glimpse of the clarity it provides:

My review of the C standard library in practice
In general, when working in C I avoid the standard library, libc, as much as possible. If possible I won’t even link it. For people not used to working and thinking this way, the typical response is confusion. Isn’t that like re-inventing the wheel? For me, libc is a wheel barely worth using — too many deficiencies in…

Comparisons in C++20
Now that the Cologne meeting is over and we’ve more or less finalized (at least before the NB comments come in) C++20, I wanted to take the time to describe in detail one of the new language features we can look forward to. The feature is typically referred to as operator<=> (defined in the language as “three-way…
