Where did software go wrong? (2020)
Software is broken, but it's not because of NPM, startups, AI, or venture capitalists. A deep dive into how we think about and produce code, and how our software systems reflect the manic state of the modern world.

Starting with microservices
Starting a greenfield project with microservices is easy. The promises are wonderful but often they are far from reality. This time I’ll share my experience on the truth about microservices when starting a project from scratch.

The Sad State of Debug Performance in C++
By now it should be (hopefully) widely known that the term “zero-cost abstractions” is a misnomer. Although, to be clear, it's more of an unfortunate name.

Removing characters from strings faster with AVX-512
In software, it is a common problem to want to remove specific characters from a string. To make the problem precise, let us consider the removal of all ASCII control characters and spaces. In practice, it means the removal of all byte values smaller or equal than 32. I covered a related problem before, the … Continue…

Literate programming: Knuth is doing it wrong (2014)
Literate programming advocates this: Order your code for others to read, not for the compiler. Beautifully typeset your code so one can curl up in bed to read it like a novel. Keep documentation in sync with code. What's not to like about this vision? I have two beefs with it: the ends are insufficiently ambitious by…

Build the Modular Monolith First
Even talking about building a monolith today, is a bit taboo. It is all about microservices at the moment, and has been for a few years. But they aren’t a silver bullet…

Hand-optimizing the TCC code generator
I am on a number of different compiler mailing lists. One of those is the mailing list for the Tiny C Compiler . Imagine my surprise when a recent email mentioned our latest series and suggested trying a similar approach to improve the code generator in TCC. I was interested to see if there were any low-hanging fruit…

Map Data: False Assumptions
Famously, engineers tend to make wrong assumptions about a lot of things: Names and time are two well-known examples. Maps are a rich source of edge cases. Especially when you start dealing with gl…

Delimiter-first code
A new top-level syntax for programming languages is proposed to show advantages of this method. New syntax is arguably as simple, but more consistent, better preserves visual structure and solves some issues in code formatting.

Jax vs. Julia (Vs PyTorch)
A while ago there was an interesting thread on the Julia Discourse about the “state of machine learning in Julia”. I posted a response discussing the differences between Julia and Python (both JAX and PyTorch), and it seemed to be really well received! Since then this topic seems to keep coming up, so I thought I’d…
