Modern Transactional Stack
Transactional databases have long been the most critical component of application design. Why? Because a steadfast database is generally the ultimate enforcement point for correctness in a messy, distributed world. Without them we’d overpay and undercharge. We’d lose riders trying to get home from the airport, and…

NP-complete isn't always hard
A common assumption I see on the ‘net is that NP-complete problems are impossible to solve. I recently read that dependency management in Python is hard because package resolution is NP-complete. This is true in principle, but the reality is more complicated. When we say “NP-complete is hard” we’re talking about…

Solving “Two Sum” in C with a tiny hash table
I came across a question: How does one efficiently solve Two Sum in C? There’s a naive quadratic time solution, but also an amortized linear time solution using a hash table. Without a built-in or standard library hash table, the latter sounds onerous. However, a mask-step-index table , a hash table construction…

C++ at the End of 2022
I must admit that some previous years for C++ might feel a bit “boring” and “stable”. New features, new standard every three years, meetings, conferences… life as usual (apart from some additional World/Economy/public Health events…).

JavaScript private class fields considered harmful
Today I mourn. What am I mourning? Encapsulation. At least in my projects. As a library author, I’ve decided to avoid private class fields from now on and gradually refactor them out of my existing libraries. Why did I make such a drastic decision?
