Helm Values Staging vs Prod: 3 Mistakes That Broke Uptime

Originally published on kuryzhev.cloud Context We had a single Helm chart deploying roughly 15 microservices, split across staging and production, with ArgoCD 2.9 syncing everything from a monorepo. The pattern looked textbook: one values.yaml as the base, then a values-staging.yaml and a values-prod.yaml to override whatever was different per environment. On paper, this is the recommended ...

AI-Assisted Engineering: Faster to Build Isn't Cheaper to Own

I like AI coding tools. I use them myself, and my teams use them too. That is probably the most important thing to say up front, because I do not mean this as an anti-AI post. The leverage is real. Scaffolding is faster. Boilerplate is cheaper. First drafts come together much more quickly. People get unstuck faster than they used to. I have seen tasks that used to chew up half a day shrink to t...

How I Fixed Broken Portrait/Landscape Gallery Alignment (and Open-Sourced It)

Why I Built a Responsive Image Strip Gallery (and Published It for Every Framework) A few weeks ago I ran into a layout problem that sounds simple on paper: put portrait and landscape photos in the same row, aligned, without cropping them into ugly square boxes. It turned out that no gallery — not Squarespace's built-in options, not the popular npm galleries — actually solves this clea...

Correctness Has a Price: We Benchmarked Fair Leaderboards

Engineering posts often end with: The new design is correct, scalable, and fast. Fast compared with what? When we changed Podium so tied players rank by arrival time instead of player ID, we added: a Lua script; a per-leaderboard sequence; a public-ID mapping; a second sorted set for ascending order. That design is fairer. It is also impossible for it to be free. So we built two benchmar...

Redis Cluster Won't Shard Your Hot Leaderboard

"We use Redis Cluster" can mean two very different things: Our dataset is distributed across Redis nodes. Every individual data structure is distributed across Redis nodes. The first can be true while the second is false. That distinction matters for leaderboards. In Podium, each leaderboard uses several Redis keys and atomic Lua scripts. Redis Cluster helps us scale a large fleet of indepen...

How to Generate E-commerce Product Pages in Bulk with AI

Article Summary Bulk-generating product pages with AI looks simple: send product attributes to a model and ask it to write persuasive copy. In practice, this approach often creates invented claims, mismatched specifications, repetitive content, prohibited wording, and formats that cannot be published across different sales channels.
