On latency, measurement, and optimization in algorithmic trading systems

"The speed of light sucks." - John Carmack ‍ Software engineers within the world of low-latency automated trading (colloquially known as "high-frequency trading" or HFT) obsess over speed. From purchasing private bandwidth between microwave towers to analyzing x86 instructions from different compiler versions, those with experience in this industry have seen colossal time and expense committed to the problem of optimizing code and network paths for minimal execution times.

The War on the Walkman

news.ycombinator.com Louis Anslow 2026-03-03 06:33:43

🗓️ On this day in 1979 the Sony Walkman was first released, marking its 46th anniversary The Sony Walkman is now an icon of the 1980s, eliciting nostalgia for the ‘good old days’ of owning music, rather than renting it. Affection for the device is now universal, but that wasn’t always the case… The sudden rise of headphone wearing pedestrians - spurred by Sony’s lightweight headsets (17% the weight of others) - caused unease about an unfamiliar new world quickly coming into view.

Two and a Half Years in GameDev

About 3 years ago, I joined a GameDev company, without any prior experience making games or hands-on exposure to this industry. Statistically, this time is not even enough’s to release a single game. But during that window, I was lucky to meet many talented people deeply involved in modern GameDev, who shared with me their career journeys, war tales, and anecdotes, and helped me shape my vision. One unexpected outcome of this switch was that many friends and former colleagues reached out to me

How to get started with Old English poetry

news.ycombinator.com Colin Gorrie 2026-03-05 11:56:15

The Shipwreck (1805), Joseph Mallord William Turner Most people who know anything at all about Old English poetry will be aware of the existence of Beowulf. Perhaps they will even have read it. But far fewer will be aware of the 90% of Old English poetry that is not Beowulf. It’s a shame, because the back catalogue of Old English poetry — the deep cuts — are well worth reading. And, in general, these poems are much easier (and shorter) to read than Beowulf. The entire corpus of surviving poet

Building a Mac app with Claude code

I recently shipped Context, a native macOS app for debugging MCP servers. The goal was to build a useful developer tool that feels at home on the platform, powered by Apple's SwiftUI framework. I've been building software for the Mac since 2008, but this time was different: Context was almost 100% built by Claude Code1. There is still skill and iteration involved in helping Claude build software, but of the 20,000 lines of code in this project, I estimate that I wrote less than 1,000 lines by ha

Edible Microlasers Could Revolutionize Food Tracking and Safety

In a delicious turn of events, scientists succeeded in taking the optics of olive oil to create the first-ever microlaser made entirely from edible materials. If commercialized, they could offer an easy and safe way to monitor food or medications from inside your body.

Your brain works differently when you're using generative AI for a task than when you use your brain alone. Namely, you're less likely to remember what you did. That's the somewhat obvious-sounding conclusion of an MIT study that looked at how people think when they write an essay -- one of the earliest scientific studies of how using gen AI affects us.
