Flutter Web SEO: Crawlable Content, JSON-LD, and Share Cards for a Canvas App

Open a Flutter web build in a browser, hit View Source, and the <body> you get back is a loading <div> and a <script src="flutter_bootstrap.js">. That is the whole page. Every heading, paragraph and link a human reads is pixels that CanvasKit painted into a <canvas> after a c

The Dedicated OCR Engine Lost to the General-Purpose Model — 300 Slower

Originally published on hexisteme notes. I had a 27B vision model running locally (IQ4_XS quantized, 15GB resident) and needed to decide whether it was worth using for OCR. The comparison was macOS's built-in Vision framework (VNRecognizeTextRequest) — a dedicated text-recognition engine, free, zer

A coding assistant drafted my Nginx config. Here’s what I still had to verify

I asked a coding assistant to draft an Nginx config for a small Laravel app on an Ubuntu VPS. It produced something usable in seconds. That is the useful part. The dangerous part is that a config can look completely reasonable, pass a quick visual scan, and still be wrong for the actual server. T

10 Vue Performance Mistakes That Only Show Up at Scale

Your Vue app feels fast when it has twenty components, one list, and a handful of API calls. Then the enterprise customer shows up with 80,000 rows, twelve nested filters, a realtime feed, and a dashboard that has been growing organically for three years. That is when the bill arrives. The frustra

Building Production-Ready AI Agents in Laravel

The dangerous version of an AI agent is not the one that gives a bad answer. It is the one that confidently calls a tool, updates the wrong record, sends the wrong email, retries itself into a loop, and leaves no recoverable trail. A prototype agent can be impressive and still be unsafe. A product

Your coding agent can write the UI. It can't see that it broke it.

Give a coding agent a failing test and it fixes itself. Give it a stack trace, a type error, a red CI log, and it reads the signal, reasons about the cause, and corrects. That loop is the whole reason agents feel autonomous on the backend. On the UI it falls apart. The agent edits some CSS, sees n

Why Most AI Agents Fail in Production

The demo is flawless. The agent reads the support ticket, categorizes it, looks up the customer, drafts a response, updates the CRM, and posts a summary in Slack. Everyone nods. Someone says, “This is going to save us hundreds of hours.” Two weeks later, the same agent has replied to the wrong cust

Upscaling can't recover what downscaling deleted — I measured how much

Here's an experiment you can reproduce. Take an image with fine structure — thin gridlines, text, sharp edges — shrink it to a quarter of its side length, interpolate it back up to the original size with bicubic, and compare against the original pixel by pixel. I measured two things: PSNR, and hi

Idempotency for Reliable APIs: A Practical Guide

Why Idempotency Matters When building APIs, network failures are inevitable. A client sends a request, the server processes it, but the response is lost. The client retries, and suddenly you have duplicate orders, double charges, or duplicated database records. Idempotency solves this by ensuring

How Lossless Log Compression Actually Works: Schema-Aware Encoding vs. gzip/zstd

Every backend engineer has had this conversation at least once: retention gets cut from 90 days to 30, or verbosity gets dialed down in production, because the storage bill for logs quietly became a line item someone in finance started asking about.
