I’m excited to revisit this series to tell you more about a new part of our infrastructure - the feature we call transforms.

Better Apps with React Server-Side Rendering

Imagine you're a web developer. You have to create an app that leverages five different data sources. The project has 26 different views built in - and don’t forget to make it fast, easy to test, and reliable. I work on creating the tools that make this kind of app as easy as possible for developers to build and manage. My name is Matthew Drake and I’m a member of the Riot Data team.

404 Tech Blog Not Found: Welcome to the Bug Blog

So, why do Bug Blogs? Well, at Riot, we believe that a fundamental component of the development process is understanding that failures can and do happen. We make mistakes because we’re humans, and humans are far from perfect. And that’s okay! What’s important is to recognize failures for what they are, work to understand why they happened, learn from them, and make needed changes based on those learnings. That’s how we grow and that’s how we get better.

Runes Reforged: A Technical Retro

Hey folks! We’re going to take a trip back in time. The year is now 20xx, and we’ve decided that it’s finally time to send one of League of Legends’ most long standing, revered or reviled features (depending on who you ask) to the meme graveyard.

That’s right - it’s time to retire runes and masteries.

Profiling: The Case of the Missing Milliseconds

Hi, I’m Tony Albrecht, an engineer on League. I’m back with some more performance goodness. In the previous article, we tracked a slowdown reported in an LCS game and an issue with Swain that was first reported by players. For this article, we’re stepping back a little further and looking at how we can measure the aggregate performance of League over an entire region, notice a dip, and then narrow down the cause. In this case, we chased a 2ms per frame drop in performance to a single missing ASCII character in our code.
