How I Built a $0/Month Ecommerce MVP Without Shopify

A founder came to me with a simple requirement: 100+ products Customers need to browse products Customers need to place orders through WhatsApp No online payments No monthly Shopify subscription The interesting part? He didn't need a traditional ecommerce platform. He needed a simple way to display products and receive orders. The Problem The original idea could easily turn into a large ecommerce application: User accounts Authentication Shopping ...

What I learned trying to benchmark local LLMs honestly

I had eight models sitting on my laptop and no idea which one I should actually be using. I could get tokens per second out of llama-bench . That told me llama3.2 was fast. It told me nothing about whether llama3.2 was good — whether the quantization I'd pulled had quietly broken something, whether the 8B model I'd been avoiding because it felt sluggish was worth the wait. So I built the thing that measures both. It's called homebench, and most of the month I spent on it went not in...

Mitigating HTTP Request Smuggling

The Problem When malformed or abnormal HTTP requests are interpreted by one or more entities in the data flow between the user and the web server, such as a proxy or firewall, they can be interpreted inconsistently, allowing the attacker to "smuggle" a request to one device without the other device being aware of it. HTTP Request Smuggling HTTP Request Smuggling exploits discrepancies in how front-end (proxy/load balancer/WAF) and back-end servers parse HTTP requests, speci...

I built a spend cap for LLM calls. It failed by 4.2x under parallel load.

Provider spending limits don't stop anything. They're alerts wearing a brake's clothing. The documented cases from this year are ugly. A developer set a $250 cap and received a $10,138 bill overnight. An AWS customer with anomaly detection enabled was charged $30,141 for a single Bedrock inference run — no alert fired. FinOps teams reported burning an entire annual token budget four months into the year. None of that is because models are expensive. It's structural: provider caps run off b...

Magic Link Audits Without Full URLs

Passwordless login looks simple from the UI, but the audit trail behind it can get risky fast. I have seen teams protect their token table carefully, then leak the same access path into logs, traces, and support dashboards because the full magic link felt "temporary enough." It is not. If a magic link can still sign a user in, it should be treated like a credential. That means your observability stack, help desk exports, and debug tooling should never become an easier place to find it than th...

A 200 response is not a page, and your policy check is grepping an empty shell

Pulse Width Modulation in ESP32

Note: This post is not completed yet. Introduction ESP32s have a peripheral module called LEDC , which stands for "LED Control" or "LED PWM Controller". It is used to dim external LEDs using a technique called Pulse Width Modulation (PWM), which works by switching the LED on and off too rapidly for human eyes to notice. Virtually all ESP32s only have one LEDC. Inside the LEDC of the original ESP32, there are 4 timers and 16 channels. Controlling the LEDC The...

Modeling SCHD's dividend growth, in TypeScript

SCHD (Schwab's U.S. Dividend Equity ETF) shows up on every "best dividend ETF" list, but rarely for the reason that actually matters: its dividend grows . The starting yield is modest — somewhere in the 3–4% neighborhood — yet SCHD has raised its dividend on the order of ~10–12% per year over its life. That's the whole game. A flat 6% yield pinned to a share count that never moves eventually gets lapped by a 3.5% yield that grows and compounds. I wanted to make that math tangible, so I built...

Microservices vs Monolith: The Quest for the Holy Grail (Inspired by Monty Python)

The Quest Begins (The "Why") Picture this: I’m sipping coffee, staring at a screen full of latency spikes, and the product manager keeps asking, “Why does our API choke whenever traffic spikes?” We’d just shipped a shiny new feature, and the monolith was groaning under the load. Honestly, it felt like we were trying to fill a bathtub with a teaspoon while the faucet was wide open. I remembered a similar scene from Monty Python and the Holy Grail — King Arthur’s knights shouting, “It’s j...

Things I Built While Figuring Out What Kind of Engineer I Want to Become

I Don't Want to Be Known for Knowing Technologies I've been thinking about something recently. As an IT student, it's easy to look at what other developers are doing and feel like you need to know everything. React. Next.js. Flutter. Kotlin. AI. IoT. Cloud. Databases. And then another framework appears. So I started asking myself a different question: What do I actually want people to remember me for? I don't have a perfect answer yet. But I think ...

An invisible character broke a security patch. Then it broke my review. Then it broke my review of the fix.

My open-source project, safari-mcp , got a security-hardening pull request from an automated scanner. The idea behind the patch was right. The patch itself un-parsed the codebase. Then the same defect infected my review of the patch, my review of the fix, and eventually the private note I wrote to remind myself to stop letting this happen. This is a story about one character, told in three acts, and it ends with a rule I now apply to everything I publish. The character U+202...

The KV Cache Is the Bottleneck: A 2026 Field Guide to Attention Variants

If you want to understand why 2026's frontier LLMs look the way they do — why one ships Multi-head Latent Attention, another interleaves linear and full attention, a third leans on sliding windows — stop looking at benchmark scores and look at the KV cache. Almost every architectural decision at the frontier this year is, at heart, a fight with the memory that autoregressive decoding leaves behind. This is a practitioner's map of that fight: what the KV cache actually costs, the lineage of te...

CPU Architecture Simplified

Why should you care? You write code. The compiler translates it. But who actually executes it? The answer is the CPU . Every program you run eventually becomes a sequence of instructions that the CPU executes. Understanding CPU architecture helps explain why: Some programs are faster than others. RAM is slower than CPU cache. Your CPU has multiple cores. A program can use multiple threads. Low-level optimizations sometimes matter. Programming concepts like loop...

I blocked accessibility overlays on 56 Shopify stores and measured what changed

Median change to the underlying markup: zero — in every one of six runs, across three samples drawn at different times. That sentence needs about two thousand words of context before it means anything, including the three occasions where I nearly published a number that was wrong. Here they are. Start with what it does not measure: whether a widget helps anyone. It measures whether a page's markup changes when the widget runs. A tool with a genuinely useful toolbar — bigger text, a readin...

Evidence-linked memory for coding agents: a reproducible alternative to replaying project history

Coding agents often inherit project context in one of two ways: replay a long transcript or project history, which is expensive and noisy; or pass along a short summary, which is compact but difficult to audit. There is a useful third design: keep an authoritative local record, derive searchable views from it, and compile a small task-specific context pack whose claims point back to exact evidence. This article explains that pattern through Qarinah , an open-source implementation...

Your AI Agent Costs Too Much Because Its Job Is Undefined

Model prices matter, but the largest waste often starts before the first token is billed. Undefined jobs make agents read too much, retain stale context, retry without a new strategy and call expensive models for routine work. The useful metric is not cost per token. It is cost per accepted task. Price the completed job, not the individual token Token prices are useful for procurement. They are a poor measure of whether an agent is economical. Suppose one model costs half a...

How to Verify a 'Trained-From-Scratch' LLM in 2026: A Provenance and Fingerprinting Guide

TL;DR — Can an outsider verify that an LLM was "trained from scratch"? In 2026, largely yes. Using only public Hugging Face artifacts — config.json , tokenizer.json , and embedding weights — you can fingerprint a model's lineage and place it on a spectrum from fully original to a straight port of a foreign base. This guide explains the method, what it can and cannot prove, and the open-weight debate that made it a 2026 talking point. Key takeaways Three public signals —...

Stop Writing CRUD Boilerplate: Generate a Complete FastAPI API From One Decorator

Stop Writing CRUD Boilerplate: Generate a Complete FastAPI API From One Decorator Every FastAPI project needs the same endpoints. GET /resource , POST /resource , GET/PUT/DELETE /resource/{id} — plus filtering, pagination, and sorting. And every project writes them by hand. Over. And over. I've seen codebases with 2,000 lines of nearly identical route handlers, where filtering is bolted on inconsistently, pagination is reinvented per endpoint, and permission checks are copy-pasted wit...

Bounded Contexts Not Borders: Why Microservices Are a Misnomer

I've spent the last decade preaching microservices, but I was wrong. What we call microservices usually means a bunch of loosely coupled and independently deployable units that are actually a misnomer. We need to focus on true functional boundaries instead of arbitrary borders. The problem starts with how we build them. We draw lines based on technical convenience, org charts, or vague requirements. Systems balloon with unnecessary complexity. Bounded contexts reflect the actual domain. T...
