Why Go Rocks for Building a Lua Interpreter

news.ycombinator.com Roxy Light 2025-09-24 10:28:01

By Roxy Light I recently needed to build a custom Lua interpreter in Go. The exact reasons aren’t important for this blog post, but neither the reference implementation — which I will be referring to as “C Lua” throughout this article — nor the other open source Go Lua intepreters I could find were a good fit for my needs. Building a Lua interpreter ended up being a rather enjoyable months-long side quest. I’ve had a number of folks ask me to write about the experience since these sorts of proj

Performance Debugging with LLVM-mca: Simulating the CPU

news.ycombinator.com Ivica Bogosavljević 2025-09-27 18:41:09

Some time ago I had a performance problem that wasn’t easy to explain by just looking at the code, since the version I expected to be faster was actually slower. Since the problem is simple yet illustrative, I am using it as a showcase on how to debug performance issues using llvm-mca. According to it’s documentation llvm-mca is a performance analysis tool that uses information available in LLVM (e.g. scheduling models) to statically measure the performance of machine code in a specific CPU.

Beyond the Hook: A Technical Deep Dive into Modern Phishing Methodologies

A technical exploration of modern phishing tactics, from basic HTML pages to advanced MFA-bypassing techniques, with analysis of infrastructure setup and delivery methods used by phishers in 2025. Introduction In 2025, phishing is still the most prevalent kind of cyber attack on the planet. Indeed, 1.2% of the global email traffic is phishing. That's 3.4 billion emails each day, but only a low number results in a compromise since "only" 3% of employees would click on a malicious link. However,

Bloom Filters by Example

news.ycombinator.com Unknown 2025-09-27 16:56:09

Bloom Filters by Example A Bloom filter is a data structure designed to tell you, rapidly and memory-efficiently, whether an element is present in a set. The price paid for this efficiency is that a Bloom filter is a probabilistic data structure: it tells us that the element either definitely is not in the set or may be in the set. The base data structure of a Bloom filter is a Bit Vector. Here's a small one we'll use to demonstrate: Each empty cell in that table represents a bit, and the nu

Five decades later, 10 out of 12 scientists died after entering the tomb of the 15th-century Polish King Casimir IV.

Scientists Launch Wild New Project to Build a Human Genome From Scratch

They’re hoping the project will answer fundamental questions about the human genome and transform our understanding of health and disease.

According to Climate Central, the US experienced 60% more power outages during the summer seasons between 2014 and 2023 than it did from 2000 to 2009. This can be due to the increased use of electricity for air conditioners, wildfires, severe weather and downed power lines.
