The SSR State Management Trap: defineStore vs defineContextStore

You ship a Next.js-style SSR app with a global user store. A month later, a user files a bug: "I logged in and saw someone else's profile." You can't reproduce it locally. Production logs are useless. The session cookie looks fine. What happened: your global store is a singleton on the server. Under concurrent requests, one request's setUser() wrote to the same object another request was reading....

Cloudflare is removing in-place DNS record type changes on June 30, 2026 — your Pulumi runs will start failing

Cloudflare announced on January 23, 2026 that changing the type of an existing DNS record via the API is deprecated. End-of-life: June 30, 2026. After that date, a PATCH or PUT against /zones/{zone_id}/dns_records/{id} that flips a record's type field — A → CNAME, CNAME → A, TXT → MX — stops being supported. The deprecation page doesn't promise a specific error code, just that "attempts to change...

I Didn’t Expect People to Care This Much About “Fancy Text”

It Started as a Tiny Side Tool Honestly, I thought this would be a “fun extra” tool. Not something people would seriously use. Because technically… 👉 It just changes text styles. That’s it. Or at least that’s what I thought. Then I Started Seeing Real Usage People weren’t just using it randomly. They were using it for: Social media bios Usernames Post captions Pro...

Step-by-Step: Deploying a Multimodal AI Model with Llama 3.2 and FastAPI 0.112 on ECS 4.0

68% of teams deploying multimodal AI models fail to hit production latency SLAs within 3 months of launch, wasting an average of $42k per failed initiative on idle GPU resources and engineer hours. This tutorial eliminates that risk: you’ll build a production-ready Llama 3.2 Vision deployment on ECS 4.0 with FastAPI 0.112, backed by benchmark-verified p99 latency under 400ms for 512x512 image + 12...

What is a REST API: Four Words That Power the Internet

The Menu You Never Questioned You’ve probably walked into a restaurant hundreds of times without ever thinking about how it actually works. You sit down. A waiter appears. You point at something on the menu. Food arrives. Simple. Comfortable. Familiar. But what if I told you that this exact same system — this quiet, organized dance between you, the waiter, and the kitchen — is how almost every...

Stop Using Python for Your Gen AI Apps, Use Go and Genkit Instead

Introduction For the last few years, every Gen AI tutorial, framework, and "hello world" has assumed one thing: that you are writing Python. It made sense at the start. The research community lives in Python, the model providers ship Python SDKs first, and the notebook culture is hard to beat for prototyping. But there is a quiet, important shift happening in 2026: the teams actually sh...

If you've been sending B2B cold emails the same way for 18 months, your reply rate just dropped to ~0% and you don't know why. I rebuilt my outreach this week after my reply rate tanked from 4% to <1%. Pulled fresh data from 5+ deliverability blogs (Autobound, MarketingProfs, HyperGen, Instantly), built a Python validator to enforce the new rules across 70+ template files in my repo, and shipp...
