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...

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’...

Building an Aruba Central Producer in Go: Four API edge cases we had to solve

A deterministic infrastructure collector sounds straightforward: authenticate, call the API, normalize the response, and write JSON. Enterprise APIs quickly make that model more complicated. While building the v0.1.0 OSIRIS JSON Producer for HPE Aruba Networking Central, we had to account for different pagination models, inconsistent response envelopes, stack-specific query behavior, more than o...
