The latest blog posts to take off on Hacker News. 80,841 posts.
Hacker News was written in the Arc lisp dialect, a dialect created by Paul Graham. Arc was implemented on top of Racket, but that has now changed. HN runs on top of SBCL since (at least) September of 2024.But why? For performance reasons. I recently noticed that Hacker News no longer uses paging for long threads. In…
In this post, I demonstrate the optimal workflow for creating new Debian packages in 2025, preserving the upstream Git history. The motivation for this is to lower the barrier for sharing improvements to and from upstream, and to improve software provenance and supply-chain security by making it easy to inspect every…
I've spent the last week or two writing code to make sense of the massive hack of data from TeleMessage, the comically insecure company that makes a modified Signal app that Trump's former national security advisor Mike Waltz was caught using. I've decided to publish my code
We showcase a critical vulnerability with the official GitHub MCP server, allowing attackers to access private repository data. The vulnerability is among the first discovered by Invariant's security analyzer for detecting toxic agent flows.
Researchers from Penn Engineering have discovered nanostructured materials that can passively harvest water from the air without energy input, enabling water-harvesting systems for arid regions.
This is part 1 of a multi-part series on grass rendering. We’ll start by figuring out how realistic grass should look like, and how herbage can be modeled with the tools we have at our disposal in real-time 3D graphics. Then, we’ll look at how to implement different methods of grass rendering in Godot. However, most…
If you don't care about the explanation and want a direct link to the simulation, here you go .
How to use the `timeout` command to terminate processes after a specified time and how to combine it with `until` for smarter shell scripting.
Explore the surprisingly different security standards we apply to webhooks versus traditional API requests.

When people started calling my personal mobile number with questions about a voluntary organisation I'm involved with, I was confused: we weren't sharing that number. It turns out that Google had decided to take the number I used to verify my identity for Google Business some years prior and start putting it in Google…
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…
Ten years ago this week, in May 2015, the JSON Web Token (JWT) became RFC 7519 . This was the culmination of a 4.5 year journey to create a simple JSON-based security token format and underlying JSON-based cryptographic standards. The full set of RFCs published together was:
The Noam Chomsky Website.
My little corner of the web for sharing wherever my interests take me.

Ever had this weird gut feeling that something is off in your code, but couldn’t put the finger on why? Are you starting your projects with the best intentions, following all best practices, and still feel like your architecture turns weird eventually?
Stephen Wolfram explores how the number of neural connections affects capabilities like language and abstraction. How far we could go accounting for neural nets and LLMS, the fundamental nature of computation, neuroscience and the operation of brains.
Whenever a new piece of technology comes out (these days, mostly AI) I go to some effort to understand it. Usually I end up writing a post about it, so I can be…
So! Suppose you’re an intrepid engineer in a nascent Developer Productivity team. Your engineering organization has decided that it wants to move towards a monorepo . You’ve heard the stories told of Google, Meta, Uber - each a large technology company with developer productivity organizations consisting of hundreds…

It’s well known that video games today are disposable pieces of slop. Modern multiplayer games tend to fall into one of two categories: they’re abandoned after a while and the servers a…
When I first learned about Diffie-Hellman and especially elliptic curve Diffie-Hellman, I had one rather obvious question: Why elliptic curves? Why use this strange group that seems rather arbitrar…
