This article is about the Y combinator, a fixed-point combinator that provides a way of using recursion in scenarios and programming languages where symbols are not available. The concept of the Y combinator itself is closely related to lambda calculus (λ-calculus) and functional programming languages. More…
In a previous post, I’ve shown how to use the rayon framework in Rust to automatically parallelize a loop computation across multiple CPU cores.Disappointingly, my benchmarks showed that this only provided a 2x speedup for my workload, on a computer with 8 CPU threads.Worse, the total “user” and “system” times…
When doing systems programming we often need to wait for something to happen. Common examples might be waiting for some data to come through a socket or waiting on a lock. We also often want to wait on any of several conditions to become true. A web server might be handling many sockets at once, waiting for any number…
I recently learned Spotify provides downloads for users’ streaming history. For me, this is over 10 years worth of data, so at the very least it seemed like a good nostalgia trip. This post covers some of my analysis of my personal export, and hopefully is a good starting place if you’re interested in exploring your…
Get an introdcution to Early Cascade, a novel process injection technique that is effective against top tier EDRs while avoiding detection.
To help crime analysts get started with python, I am early releasing Data Science for Crime Analysis with Python, an introductory book for analysts.
If you are not sure if the code you plan to commit is acceptable (e. g. when taking code that was submitted with a problem report), ask a developer who is familiar with that part of the system for review. If you're new to the Project, check with your sponsor.

In distributed systems, for instance when scaling out some workload to multiple compute nodes, it is a common requirement to select a leader for performing a given task: only one of the nodes should …
Resolving PS2SDK Soft Reset Issues
I've been thinking a lot about personal data lately: where it's stored, how to extract it, and what to do with it. Here's where I landed.
MIT student who enjoys performance engineering, compilers, and creating unconventional code
Sometimes, programming projects are too easy and boring. Sometimes, they're too hard, never ending or producing subpar results.
I did a livestream where I talked about Object Storage. The how and why. The Bad Old Days. And also the neat and interesting stuff just beyond the basics. I figured I'd cover that in text as well.
Inspiration of how we can use PDF as an attack vector and perform multiple attacks with huge subsequences to the victim.
OCaml's let … = … in … is very confusing. When nested, you can't tell how it's nested.
Learn how to use PaliGemma, a vision language model developed and released by Google that has multimodal capabilities.
An expose on Implicits and Local Coherence
Using a full-featured RPC framework for IPC seems like overkill when the processes run on the same machine. However, if your project anyway exposes RPCs for public APIs or would benefit from a schema-based serialisation layer it makes sense to use only one tool that combines these—also for IPC. Microservices for…
Parenthetically Speaking: Articles by Shriram Krishnamurthi
What Is Declarative Programming Broadly speaking, there are two ways to program/instruct a computer to perform a task, they are imperative...
MP 90: Building a complete Django project from a single file. Note: This is the first post in a series about building a full Django project, starting with a single file. This series will be free to everyone, as soon as each post comes out. 1 For a long time,
I first encountered Jenkins in 2007 while contributing to the Apache Nutch project. It was called Hudson back then. The nightly builds for the project ran on Hudson at that time. I remember sifting through my emails and reviewing build result notifications to keep an eye on the patches that got merged into the trunk…
tl;dr : Software shadow stacks could deliver up to 8x faster stack trace capturing in the Go runtime when compared to the frame pointer unwinding that landed in go1.21. This doesn’t mean that this idea should escape from the laboratory right away, but it offers a fun glimpse into a potential future of hardware…
Or: The Most Expensive Linked List I’ve Ever Written
As far as I know, the next meeting of EmacsATX, the Austin Emacs Meetup group , has a planned topic: Org mode . I was going to make a post about the common Org functions I use frequently, but I thought that I should start with common commands I used for generic Emacs when I started using it more than twenty years ago…
tl;dr: programming book authors: put all the code in the book! An extreme antipattern for a programming book is “download the author’s idiosyncratic library code from some random URL an…
