How to Build Accessible Custom Dropdowns (Comboboxes) That Actually Work

Originally published on the AccessGuard blog. After our post on accessible modals resonated with so many of you, we wanted to tackle another notoriously tricky pattern: the custom dropdown, or combobox. Native select elements are accessible out of the box, but the moment you need custom styling, searchable options, multi-select, or grouped items, you end up reimplementing a lot of browser behavio...

How We Cut API Response Time from 2.3s to 180ms Using Redis + Smart Caching

p95 latency dropped from 2.3 seconds to 180 milliseconds. Same hardware, same database, same traffic. The only thing that changed was how we cached — and I don't mean slapping @lru_cache on a function. I'm writing this because every Redis caching tutorial I read before this project showed me the same 15-line example: redis.get(key) or fetch_from_db(). That code works in a notebook. It will absolu...

Private AI Inference on Midnight: Keep Your Data Secret, Prove Your Output is Real

Introduction There is a quiet problem at the heart of modern AI: the data powering personalised outputs often belongs to someone who never consented to share it. Artists, writers, musicians their work gets swept into training pipelines, their style replicated, and they receive nothing in return. But what if it didn't have to work that way? This tutorial shows you how to use Midnight a...

Making illegal state unrepresentable

A couple of years ago, I wrote that The Builder pattern is a finite state machine!. A state machine consists of states and transitions between them. As a developer, I want to make illegal states unrepresentable, i.e., users of my API can't create non-existent transitions. My hypothesis is that only a static typing system allows this at compile-time. Dynamic typing systems rely on runtime validatio...

Stop memorizing JS — think in execution context

Forget remembering JavaScript syntax; it's a crutch. What if I told you that the key to truly understanding JavaScript isn't memorizing endless functions and methods, but grasping how the code actually runs? This article is about shifting your focus from rote learning to thinking about JavaScript's execution context. Every time your JavaScript code runs, the engine creates an "execution context....

Why use an AI gateway at all?

Before picking a platform, I think it's worth asking: why even bother with an aggregation layer? For me, the pain point became obvious once I started juggling more than two model providers. Different API keys, different billing cycles, different request formats, and the constant context-switching between docs. If you're building anything that needs to switch between GPT for reasoning, Claude for ...
