The naive way to accept file uploads is to POST them to your API, let the server read the bytes, and write them to object storage. It works until the files get large or the traffic gets real. Now every upload crosses your infrastructure twice, once from the client to your server and once from your server to storage, and your server holds the whole file in memory or on disk while it does. On a serverless function it is worse, because functions have request-size and duration limits that a big uplo...

security #api #webdev #discuss The chat went live at 2 PM. By 2:14 it was a war zone. I thought adding real-time chat to my dev blog would spark pair-programming threads. Instead, bots flooded it with phishing links and slurs. One bot even dropped an oddly specific threat about my home city. I flipped on request logging. In the next 24 hours it logged 52 distinct attacker hostnames. IP bans did nothing. They came back from new IPs, new ASNs, new registrars. IP bans felt like swa...

Google's Custom Search JSON API is closed to new customers, and existing customers have until 2027-01-01 to move off it. That deadline takes searchType=image with it. I maintain cse-bridge , a small self-hosted service that speaks Google's customsearch/v1 wire format on top of your own SearXNG instance, so migrating is a base-URL change rather than a rewrite. Web search shipped first. This week I added image search — and it turned out to be much less mechanical than "map some mor...

Most AI image generators look like a prompt box with a Generate button. That is also how my first version started. But once real users entered the workflow, the difficult problems appeared somewhere else: browser refreshes, external task IDs, reference images, partial failures, credit refunds, private assets, and public artwork moderation. While building Magggic , I learned that an AI image generator is less like a form submission and more like a small distributed job system. This artic...

If your app stores files and you want real preview environments, you eventually hit the same wall: each preview needs its own storage, so you start provisioning a bucket per environment. That sounds cheap until you write it down. For every ephemeral environment you create a bucket, attach a policy, mint an IAM role or access keys, set CORS, add a lifecycle rule so it eventually cleans up, wire the credentials into the preview's config, and register a teardown step for when the PR closes. Then yo...

Introduction: Moving Beyond Traditional XML Layouts Android development has evolved significantly. The days of managing complex XML layouts with findViewById or basic View Binding are fading fast. Modern Android development demands clean architecture, reactive state management, and declarative UI tools like Jetpack Compose. In this deep dive, we will explore how to structure scalable, maintainable, and testable native Android applications using the Model-View-ViewModel (MVVM) architecture al...

A reverse proxy sits between clients and one or more upstream services. Instead of clients communicating directly with your application, every request first passes through the proxy before being forwarded to an upstream. Mature reverse proxies such as Nginx, Envoy, and HAProxy do much more than simply forward requests. They perform tasks such as load balancing, health checks, rate limiting, metrics collection, and much more. I wanted to better understand how some of these concepts work in ...

Recently, I've added a bunch of hype-monsters to my AI Werewolf : Kimi K3 Qwen 3.8 Max, Qwen 3.7 Plus, Qwen 3.7 Flash MiniMax M3 Plus the ones I've had for a while DeepSeek V4 Pro and Flash GLM-5.2 Sakana Fugu base and Ultra The last one is Japanese, not Chinese, but it was in the news a month or two ago and it belongs in this story. I sat down to write about how slow Chinese models are. Because they are all annoyingly slow even with a small context. I had the num...

If your files already live in Amazon S3, the pitch for storage that branches with your database is appealing but the word "migration" makes it sound like a project. It mostly is not. Neon's object storage speaks the S3 API, so the code you already wrote, the AWS SDK calls and presigned URLs, keeps working. What changes is how you point the client and where the bucket comes from, and that is a small, mechanical diff. The actual data move is a copy loop you can run once. The one thing to do up fro...

There's a workflow that basically didn't exist three years ago and now half the job-seekers I know use it: ask ChatGPT, Claude, Gemini, or any AI to write your resume bullets, get back beautifully structured text… and then spend forty minutes mangling it into Word or a drag-and-drop resume builder, fixing bullet indentation and font sizes by hand. Here's the thing that bugged me: LLMs already speak Markdown. Ask any chatbot for a resume and you get ## Experience , **Senior Engineer** , -...

What started as a vision for mapping urban gardens has evolved into something much bigger. Over the past weeks, we've built a complete decentralized ecosystem that connects IoT sensors, robots, and communities using Monero (XMR) and MYZ tokens. The Journey: From Gardens to Streets It all began with a simple idea: create a map for urban gardens. But we quickly realized that a map alone wasn't enough. We needed a full system that could: Monitor soil health in real-time Autom...

Part 3 of the User Connectivity Architecture series. Introduction The first post in this series described the pattern: a heartbeat on a timer, an Event Hub, a worker writing sessions into Redis, and Redis key expiration driving facility online/offline status. One detail matters later. The heartbeat interval is not hard-coded in the client. The API tells the client when to call next, and the default is 30 seconds. The second post covered two years of running that in product...
