Blast Radius: What a Leaked Secret Breaks

Why identity-local signals and topology signals are two layers of the same blast radius The credential with the widest blast radius sometimes has no secret to flag. See how GitGuardian and Anyshift rank risk by what actually breaks. By Louis Fradin • 23 Jul 2026 • 7 min read 👉 TL;DR: Identity-local signals show whether a credential or machine identity is risky. Topology signals show...

Compressing an image to exactly 50KB in the browser, with no server

Indian government exam portals have a rule that has quietly shaped a lot of my code: your photo must be under 50KB. Not "small". Not "optimised". Under 50KB, or the upload is rejected. Every free tool I found for this wanted me to upload the photo to a server, wait in a queue, and create an account. For a file I just wanted to shrink. So I wrote it myself, in the browser. This post is about the ...

I Built Software for Families Who Share a Holiday Home (So WhatsApp Stops Running the Place)

Sharing a holiday home with family or friends is great until the admin starts. Who’s in next weekend? Did someone already claim Easter? Who was meant to book the cleaner? Where’s the WiFi password / insurance cert / “how to winterize the outdoor taps” note? For most groups this lives in five group chats, a half-maintained Google Calendar, and a Drive folder nobody trusts. I kept running into...

WWDC’26 Viewing Guide

I've been following WWDC since 2011* and over the years I've developed my own process for watching sessions. Over the past 15 years, I've gone through all the stages from denial (I missed all the videos, for example, in 2014, when I couldn't accept Swift's appearance), to bargaining ("I still CAN watch all of them!") and finally accepting and creating my own approach to watching WWDC. So here's ...

Mythos Asks the Right Question. It Doesn't Answer It.

AI is compressing exploit timelines. The real question isn't whether your vulnerability management playbook needs to change, it's which part of it you've been getting wrong all along. The conversation happening in security circles right now goes something like this: Mythos is here. Exploit timelines are collapsing. Does the vulnerability management playbook need to change? The honest answer is

Displaying async values in Flutter

The build method in Flutter widgets is synchronous. That means it doesn’t like to wait for anything. But sometimes, we need to wait for a value to arrive in order to display it. Let’s think of a simple weather app that displays only the temperature of a city. The app needs to make a request to the backend, get the temperature value, and finally display it. It will have to wait for a response from...

Good Documentation Explains the Decision, Not Just the Code

A pattern I’ve seen many times in software projects is that documentation starts too late and documents the wrong thing. A team ships a feature, the code works, the tests pass, and everyone moves on. Maybe someone adds a README section, maybe not. If they do, it usually explains how to run something, how to call an endpoint, or what a component does. That kind of documentation is useful, but it o...

OpenWorker: Andrew Ng's Local-First AI Coworker, Explained for Developers

OpenWorker shipped in late July 2026. It is MIT-licensed, runs on your own machine, and takes your API key instead of selling you inference. The pitch is narrow and worth repeating exactly: it is an agent that hands you finished work, not a chat transcript. A drafted document on disk. A Slack reply with the real numbers in it. A calendar that has actually been rearranged. There are a lot of desk...

J-space in practice: using Anthropic's Jacobian lens to decide what an LLM can forget

Anthropic published Verbalizable Representations Form a Global Workspace in Language Models on July 6, and the vocabulary it introduced is suddenly everywhere: J-space, the Jacobian lens, a global workspace inside Claude. Most of the discussion so far is about interpretability and alignment auditing, which is fair, since that is what the paper is about. I had a narrower and more mercenary question...

Dockerfiles: Building and Running a Node.js Application in a Container

Introduction Containers provide a consistent way to package applications together with the dependencies and configuration required to run them. A Dockerfile defines how that container image is built. In this project, a Node.js application was containerized using a custom Dockerfile, with the image built, tested, inspected, modified, and rebuilt throughout the implementation. The proj...

The Shift to Edge-Computing: Middleware Security and Scaling

Originally published on tamiz.pro. The traditional client-server model, with its centralized data centers, is rapidly yielding to a distributed paradigm: edge computing. This shift isn't merely about moving servers closer to users; it fundamentally redefines how middleware operates. Middleware, the critical software layer that enables communication between different applications or components, mu...

The Return of the Robot: Why Humanoid Form Factors Are Finally Working

Originally published on The AI Prism For decades, the humanoid robot was the ultimate punchline in Silicon Valley. Every few years, some demo would go viral. A clunky metal bot would slowly walk up a ramp, pause, and immediately faceplant into the carpet. We had robots that could weld car frames perfectly, but we couldn’t build one that could walk up a flight of stairs without tipping over. ...

How to Build an AI Kill Switch (and Why Every Agent Needs One)

An AI kill switch is a single control that stops an autonomous AI agent immediately. It halts everything the agent is doing at once and cancels work that is already in flight, without you first having to diagnose what went wrong. Every agent that can take consequential actions needs one because, when an agent goes off the rails, the failure is usually fast, automated, and self-amplifying. By the t...

Struggling to start coding from scratch even though I understand syntax when reading code

How do I think I’m currently learning programming (JavaScript) and I’ve noticed a problem with my learning process. I understand the basic concepts like variables, loops, functions, arrays, and objects. When I read code written by others, I can usually follow along and understand what it does. However, when I try to solve a problem on my own or start coding from scratch, I often get stuck and don’...
