Modern computer systems are quite fascinating.

At this year’s ECOOP, the Institute for System Software will be attending with the almost complete team and we’re going to present on a variety of topics.

It’s February!

Over the past years, two major players invested into the future of Python.

Modern CPUs, operating systems, and software in general do lots of smart and hard-to-track optimizations, leading to warmup behavior, cache effects, profile pollution and other unexpected interactions.

Most research on programming language performance asks a variation of a single question: how can we make some specific program faster?

Today is the 31st of July 2025, and from tomorrow on I’ll be “between jobs”, or as Gen Z allegedly calls it, on a micro-retirement.

Last year, we looked at how well sampling profilers work on top of the JVM.
