Una novedad en Serverless bajo la lupa: AWS Lambda Web Functions

Introducción AWS anunció Lambda Web Functions, una forma de ejecutar aplicaciones web y APIs sobre Lambda ejecutando directamente un servidor HTTP de Node.js, sin adaptadores ni handlers por evento. Aquí te describo mi propio análisis. Este artículo no pretende ser una guía de cómo usar Lambda Web Functions. Hago un recorrido corto por las características que importan, referencio blogs de colegas y muestro mi propio enfoque de cuándo utilizarla y cuando No. Para no quedarme en la teoría, a...

How AI Agents Verify Work On-Chain (and Why Most Do It Wrong)

How AI Agents Verify Work On-Chain Most "AI agent" projects stop at the demo. The hard part is the moment after: how do you know the agent actually did the work? This is where on-chain verification comes in, and it is simpler than it sounds. Three mechanisms that actually work 1. Hash commitment. Before an agent starts, you commit to a hash of the expected output. When the agent finishes, you reveal the preimage. If the hash matches, the work existed before the claim was ma...

I Turned My GitHub Commit Graph Into Art You Can Frame

I was looking at my GitHub profile the other day - 847 contributions in 2024. All those late nights, bug fixes, and "fix: finally works" commits... and they just live as little green squares that disappear when you scroll. So I thought - what if I could print it? Frame it? Actually put the year I locked in on my wall? So I built Commit Print . What it is You type your GitHub username, pick a year, and it generates a clean, print-ready poster of your contribution graph. ...

Duplicate Reminder Processing: Prefer Idempotency Beyond 5-Minute Queue Deduplication

Short answer: if a shipment reminder can be delivered twice, assume at-least-once queue processing and claim a durable idempotency key before sending; queue-level deduplication is a useful filter, but its 5-minute window is not the correctness boundary. For a media shop sending a shipment update to many subscribers, I would choose durable send keys over deduplication alone. Ack only after the update has been safely persisted or sent. The catch is operational: the send-key store becomes part o...

Sub-20ms UK Companies House API: Address Sanitization, KYB & Balance Sheet Extraction

The live website demo is already running smoothly and handling real-time lookups with sub-...

Writing Email Sequences for a Niche Audience: A Practical Framework

Disclosure: this post was written with AI assistance. Generic email sequences fail in niches because niche audiences notice immediately when you don't understand them. A bookkeeper for dental practices, a climbing gym, a B2B tool for logistics planners: each audience has its own vocabulary, worries and buying cycle. This framework helps you write a short sequence that sounds like it was written by someone inside the niche. Step 1: Collect the audience's own words Before wri...

Building an AI bug-fixing agent that runs inside your GitHub Actions runner

Disclosure: I'm building a product around this (bugzero). This article was drafted with AI assistance, then reviewed and edited by me. Production errors are a good fit for an AI agent. There is a stack trace, there is a repository, and "done" has a clear definition: a pull request that a human reviews. What bothered me was the usual shape of these tools. You give a SaaS read access to your repositories, and often your AI key as well, and hope for the best. So I started from one rule: ...

Show HN: Stoke Money – Personal finance app built around a cash flow forecast

Hi HN, I've been through many finance tracking apps, starting with Personal Capital, then Monarch, and most recently Copilot. None of them have worked perfectly for my needs. All of these apps tend to model “cash flow” as the net sum of your transactions during a month, yet while credit card charges are reported immediately, they are typically deducted from checking (cash) accounts the following month when the bill is due. As a result, I've always had to maintain a separate spreadsheet to track ...
