Tbh I had no idea this was even a thing until recently. I've been working with Rails for a while now and somehow never came across it. So let me explain it the way I understood it. You know how we normally do associations in Rails, User has many Posts, Post belongs to User. Two different models, two different tables. Simple. But what if a model needs to reference itself? Like same table, same mode
On March 29, 2024, Andres Freund — a Microsoft engineer and PostgreSQL contributor — noticed something odd while investigating unexplained CPU usage in SSH on a Debian testing build. liblzma, the compression library bundled with XZ Utils, was performing extra work it had no business doing. After careful analysis, Freund had found one of the most sophisticated software supply chain attacks ever dis
The Counter Galois Onion (CGO) Migration: Tor's Cryptographic Engine Swap If you've ever dug into Tor's internals, you know the network is a masterpiece of practical anonymity. But like any long-running system, its crypto stack was starting to show its age. Enter the Counter Galois Onion (CGO) Migration - one of the most significant under-the-hood upgrades Tor has seen in years. It's a fundament

Why I built another Ruby test runner inspired by Playwright Test Ruby already has great testing tools. If you are building Rails applications today, you probably use one of these combinations: RSpec + Capybara Minitest + Capybara Rails system tests Maybe Selenium, Cuprite, Ferrum, or Playwright through Ruby bindings These tools are mature, battle-tested, and widely used. So the natural question
By QuantaLabs | April 2026 | quantalabs.cc | quantachain.org Five days ago, an independent researcher named Giancarlo Lelli broke a 15-bit elliptic curve key on a publicly accessible IBM quantum computer and collected a 1 BTC bounty from Project Eleven. The result was debated — some Bitcoin developers showed the winning result could be replicated with random noise, suggesting limited true quantum
Adding a third person to an encrypted conversation seems like it should be simple. It isn't. The cryptographic properties that make 1:1 messaging secure — forward secrecy, post-compromise security, deniability — become significantly harder to preserve as group size grows. When Signal introduced group chats, they faced a problem that doesn't exist in 1:1 messaging: how do you efficiently encrypt a
