Last month, I got an invitation to Stripe Sessions 2026, and I still do not know exactly why. Maybe it was because my title says Director of Engineering at Toss. Maybe it was because I have been spending too much money on AI tools, and many of those payments quietly
The next book club selection with Ms. Salle was the Earthsea Cycle by Ursula K. Le Guin. The first book I read in the club was The Dispossessed, and I became almost obsessed with the beauty of her prose. I even tried to imitate her writing style for a while.
In the previous post, I set up Gemma 4 locally with MLX and connected it to my usual local-model workflow. That post was mostly about the environment itself: getting the model running, exposing it through an OpenAI-compatible endpoint, and making it usable from tools like Open WebUI. Once that was
In my previous post, I explored what it looks like to run coding agents with local LLMs on an M3 Ultra Mac Studio. That write-up was mostly about the environment itself: treating a single machine as something closer to personal infrastructure, capable of hosting multiple models and running them continuously
Introduction I started Yogurting in 2002 at Taff System, a Korean game studio that later became NTIX Soft. I began as the lead server programmer and later took on the role of producer. This post is also available on Medium. If you’re a paid Medium member and happen to
This past week, Crimson Desert has been everywhere, sitting right at the center of the conversation before launch. There were interviews, technical demos, and carefully edited gameplay clips coming out of Pearl Abyss, each one trying to show a bit more of what the game could be. And almost immediately,
Baseball is back now in 2026. Yes, we had the World Baseball Classic (Korea had extreme ups and downs, which was thrilling), and the Cactus League. But this past Wednesday was the real return of baseball. The 2026 season opened with a single game, just one, between the San Francisco
Introduction Last week, I was back at GDC for the second year in a row personally (as an indie game dev wannabe). I have been coming on and off since around 2000s—not consistently, but enough times to have a sense of what the conference feels like when it is
1. Introduction Last year, I spent some time thinking about how to invest the incentives from my previous employer. Instead of putting everything into stocks or something more conventional, I ended up buying a personal desktop machine with unusual power: a Mac Studio M3 Ultra with 512GB of memory and
A few days ago, I happened to notice that not a few people are still reading an article I wrote almost three years ago about Python on macOS. That surprised me a little. In tech years, three years is almost eternal. Back then, Intel Macs were still common. Apple Silicon
1. Introduction It’s no longer just hype: coding agents are everywhere. I’ve been using Claude Code heavily at work. My current company runs on Spring Boot with Kotlin, while my previous one used Go. I understand our business logic well and the kinds of problems we solve every
Speaking of the year-end, I had a surprisingly peaceful long vacation this time, since we didn’t go on any road trip. In the first half of the break, I dusted off my Steam Deck and finally dug into a game that had been waiting in my library for a
