We are excited to attend #RUSTasia!?As a company with deep roots in the PL community, we're looking forward to connecting with Asia's #Rust developers, sharing our experiences with #functionalprogramming, and discovering fresh perspectives.

In this episode of Signals & Threads, In Young and Ron touch on the porous boundaries between #trading, #research, and #softwareengineering, which require different sensibilities but are often blended in a single person. They discuss the tension between flexible research tools and robust production systems; the challenges of #ML in a low-data, high-noise environment subject to frequent regime changes; and the shift from simple linear models to deep #neuralnetworks. https://lnkd.in/gByVWdin

Will we see you at #SREcon Americas??We're looking forward to connecting with engineers who enjoy building resilient, high-performance distributed systems and managing complex infrastructure at scale.

In this month's #puzzle, test your spatial reasoning by positioning diagonal mirrors in a 10x10 grid to connect the start and ends of laser beams. Each laser's path must have segment lengths that multiply to match the clue numbers, with no mirrors allowed in adjacent cells. Note: Please hold off on sharing any puzzle theories or solutions until the end of the month when the challenge wraps up. We want to keep the puzzle fun and spoiler-free for everyone. https://lnkd.in/eNwH4U2a

We're looking forward to connecting with fellow physicists at the APS Global Physics Summit.?Visit our booth to talk about some interesting parallels between solving problems in #physics and navigating complex financial markets.

Jane Street is at #PPL2025 this week, where we're enjoying meeting fellow technologists who are passionate about programming languages, compilers, type systems, and software development.?Stop by our booth to say hello!

In this #TechTalk, Tudor Brindus, a software engineer at Jane Street, shares his expertise on reducing jitter—deviations from mean input processing times—in #lowlatency systems. Maintaining consistently low #jitter in a trading system allows us to offer tighter markets without incurring additional risk. Using a simple memory ping-pong application as a case study, Tudor walks through how to identify and resolve common sources of jitter caused by both #Linux kernel and microarchitectural conditions. https://lnkd.in/ehieKX4D

This month's #puzzle is delightfully cryptic: examine the word list and incomplete phrases. The rules aren't spelled out, that's part of the mystery. Can you find the proper noun solution? Note: Please hold off on sharing any puzzle theories or solutions until the end of the month when the challenge wraps up. We want to keep the puzzle fun and spoiler-free for everyone. https://lnkd.in/g9BxM8i3
