Profiling Python and Ruby using eBPF
tl;dr In our continued efforts to expand and improve your profiling experience, we are excited to announce new additions to our language support: Ruby and Python. All the features that are described in this blog post have recently been released as part v0.26.0 of Parca Agent. ~~While currently these language supports are in beta, they can be enabled using the --enable-ruby-unwinding and --enable-p
How do Ruby & Python profilers work?
Almost all of these profilers live inside your process Before we start getting into the details of these profilers there’s one really important thing – all of these profilers except pyflame run inside your Python/Ruby process. If you’re inside a Python/Ruby program you generally have pretty easy access to its stack. For example here’s a simple Python program that prints the stack of every running
Generational GC in Python and Ruby - Pat Shaughnessy
Both the Ruby and Python garbage collectors handle old and young objects differently. Last week I wrote up the my first half of my notes from a presentation I did at RuPy called “Visualizing Garbage Collection in Ruby and Python.” I explained how standard Ruby (also known as Matz’s Ruby Interpreter or MRI) uses a garbage collection (GC) algorithm called mark and sweep, the same basic algorithm dev
Visualizing Garbage Collection in Ruby and Python - Pat Shaughnessy
Note: This post is based on a presentation I just did at RuPy in Budapest. Instead of just posting my slides I thought it would be more useful if I wrote it down as a blog post while it’s still fresh in my mind. You can also watch the video recording of the presentation. FYI I’m planning to do a similar presentation at RubyConf, except I’ll remove the Python info, and instead compare how GC works

Announcing Topaz: A New Ruby — Topaz 0.1 documentation
Announcing Topaz: A New Ruby¶ Posted: February 6, 2013 I’m extraordinarily pleased to today announce Topaz, a project I started 10 months ago, to create a brand new implementation of the Ruby programming language (version 1.9.3). Topaz is written in Python on top of the RPython translation toolchain (the same one that powers PyPy). Its primary goals are simplicity and performance. Because Topaz bu
The Full Monty - from Ruby to Python n00bie
Ruby developers are a pretty spoilt bunch these days. The community has overall done a great job of rolling many of the advances in modern development practice into the tools and conventions we unconsciously put to work every day. Now I wonder what life is like in the Python community? Like many Rubyists, I've played around with Python and Jython on and off. But nothing serious. And although you c
Dynamically adding methods with metaprogramming : Ruby and Python - /code/blog
I came across an interesting post Metaprogramming: Ruby vs. Javascript, which discusses and contrasts about how metaprogramming can be implemented in Ruby and Javascript. I thought it might be fun to document the same from a python perspective as well. Here are the discussed samples. All the ruby code is quoted from from the blog post linked to above whereas the python code is what I wrote. 1. Ini
