39. Fast, Memory-Efficient Hash Table in Java: Borrowing the Best Ideas
One day, I ran into SwissTable—the kind of design that makes you squint, grin, and immediately regret every naive linear-probing table you’ve ever shipped. This post is the story of how I tried to bring that same “why is this so fast?” feeling into Java. It’s part deep dive, part engineering diary, and part cautionary tale about performance work. 1) The SwissTable project, explained the way it feels when you first understand it SwissTable is an open-addressing hash table design that came out of Google’s work and was famously presented as a new C++ hash table approach (and later shipped in Abseil).

55. How well do you know C++ auto type deduction?
One of the most iconic C++ features is the language’s ability to deduce types with the auto keyword. In this post, I’ll give a series of code snippits. Your job is to assess what will be deduced for v in each case. Determine for each: The deduced type If it is a value, an lvalue or rvalue reference, or a pointer Which CV qualifiers are applicable Some of these may not even compile, so “this won’t work” is a totally valid answer.
