How Effective are Classic Lookup Optimizations for Rails Apps?
We know
that Ruby and especially Rails applications can be very dynamic and pretty large.
Though, many of the optimizations interpreters and even just-in-time compilers
use have been invented in the 1980s and 1990s before Ruby and Rails even existed.
So, I was wondering: do these optimizations still have a chance of coping
with the millions of lines of Ruby code that
large Rails apps from Shopify, Stripe, or GitLab have?
Unfortunately, we don’t have access to such applications.
As the next best thing, we took the largest Ruby benchmarks we could get our
hands on, and analyzed those.

Reducing Memory Footprint by Minimizing Hidden Class Graphs
Tomoharu noticed in his work on the eJSVM,
a JavaScript virtual machine for embedded systems, that quite a bit of memory is needed
for the data that helps us to represent JavaScript objects efficiently.
So, we started to look into how the memory use could be reduced
without sacrificing performance.

Effortless Language Servers
Ever since my blog post in 2016, I have wanted a good language server for SOM and Newspeak.
Though, I didn’t really have the time to implement more than a few features.
I am working at the
School of Computing
at the University of Kent. My work focuses on programming language
implementation techniques, complex concurrent systems, and tooling.
