Coding with AI

From Copy-Paste to Autonomous Agents: A Subtle Introduction

From Copy-Paste to Autonomous Coding Agents: A Subtle Introduction Hello, my name is Taeseo Um, currently on the ML team at HyperAccel. There is a running joke among developers that our job has always been about googling the issue, clicking the first link that pops up, then copying from Stack Overflow. In some ways, the arrival of AI coding tools didn’t change what we do — it just made us dramatically better at it. Over the past few months, our team has ridden almost every wave of AI-assisted development, from the earliest interactions to the autonomous agents we rely on today. Here’s what that journey looked like, what we learned, and where we think it’s all heading. ...

Building an Internal Development Environment with Kubernetes Chapter 1: Why Kubernetes?

Building an Internal Development Environment with Kubernetes Chapter 1: Why Kubernetes? Hello! I’m Younghoon Jun, a DevOps Engineer on the ML team at HyperAccel. For those of you reading this, what kind of environment do you develop in? I imagine you’re working in various environments—local setups, SSH server access, cloud services, and more. HyperAccel develops on an environment built on top of a Kubernetes cluster. We spin up Pods based on devcontainers pre-configured with the packages needed for development, then connect to the container to do our work. To make things easier for our internal developers, we’ve created and provided a Devcontainer Portal. ...

Polyhedral Analysis

Polyhedral Analysis

Today I brought a somewhat different topic. Have you ever thought it would be great if a compiler could automatically transform loops for optimization or parallelization while using it? Compiler engineers have had the same concerns. One approach that emerged is the polyhedral compiler, which is used by LLVM’s Polly project and MLIR’s affine dialect. Today I’ll introduce this approach. Basic concepts Before going into detail, let’s go over some basic concepts. Most of these are easy to encounter with a little linear algebra. ...

CES 2026 Key Highlights from a 2025 Participant (feat. SAMSUNG, SK, LG)

CES 2026 Key Highlights from a 2025 Participant (feat. SAMSUNG, SK, LG) Hello! I’m Hyunjun Park from the HyperAccel ML Team. CES, which started in Las Vegas on January 6th, successfully concluded on January 9th. I participated in last year’s (2025) CES and operated the HyperAccel booth, and based on that experience, I’d like to review this year’s (2026) CES. Some might wonder why I’m posting this now instead of last year. ...
