My agents kept overwriting each other, so I gave them claims

I run several agent sessions in parallel, each in its own project, all on the same machine. For a while I believed that was safe because every session had its own repo. It wasn't. Sessions reach outside their home tree more often than you think, a memory file here, a shared config there, a quick fix...

I built an AI that writes like me, and I'm measuring how much it fails

Everyone can now spot machine text on sight, the em-dashes, the "you're absolutely right", the invented technical terms nobody at any job ever used. I write a lot with agents, and I did not want my published words to smell like that. So I built hyphos, a small open tool that learns how I actually wr...

What my agents are allowed to remember

Every agent platform ships memory now. Persistence across sessions went from a trick to a checkbox sometime this year, and I expected that to settle the question. It didn't. My agents remembered plenty. They just never remembered anything useful, and the first time I audited the store I found out wh...

Every hole in the gate is signed

A routine commit in my hub repo tripped the content screen last week on text that had been fine for weeks. The screen is the pre-commit door that refuses anything matching my leak patterns, and the text it refused was the kind the hub exists to hold: the names it is allowed to name, the banned terms...

All command output below is from real local runs, not fabricated. We maintain sentinel-scan-cli, a free, zer...

We’re running an online hackathon for building concurrent AI agents — Sep 5–6

We’re joining forces with daily.dev and Hyperskill to organize the Hackathon for Building Concurrent AI Agents - September 5–6, 2026. 🚀 Most multi-agent systems today are still built around sequential workflows: one agent does its part, waits, hands work to another, and the whole system moves step...

Atlassian Now Trains Its AI on Your Work by Default — and Full Opt-Out Is an Enterprise Feature

If you run a team on Jira or Confluence, the deal changed on 17 August and the change was opt-out. From that date, by Atlassian’s own account, the content your team writes into its Cloud products — Confluence pages, Jira tickets, the descriptions and comments where the actual work lives — is used by...

Building an Open Turkish EV Charging Intent Dataset

Electric-vehicle assistants rarely have just one job. A short Turkish question may ask for a nearby station, a charging-price comparison, help planning a route, or an explanation of battery health. Before an application can retrieve current data or generate an answer, it needs to identify that inten...

.NET 10 NU1015: Fix PackageReference Without Version Restore Failures

.NET 10 NU1015 turns a PackageReference without a version into a restore error. I like the stricter default because an unbounded direct dependency can quietly resolve the lowest package version. The catch is that versionless XML is also the correct shape for NuGet Central Package Management (CPM). A...

Proof-of-Antiquity vs Proof-of-Stake: Why Hardware Diversity Beats Wealth Concentration

When Satoshi Nakamoto designed Bitcoin's Proof-of-Work consensus, the goal was simple: one CPU, one vote. What actually happened was very different. ASIC farms centralized mining into industrial warehouses, and the "one CPU" vision became "one warehouse, one vote." Proof-of-Stake was supposed to fix...

How to test your LLM app for prompt injection: promptfoo vs garak vs Giskard vs PyRIT vs sentinel-scan-cli

If you're shipping anything with an LLM in the request path (a support bot, an agent that calls tools, a RAG pipeline reading untrusted documents) you eventually have to answer "did we actually test this for prompt injection, or did we just eyeball it." There are a handful of open source tools that...

Cheap OpenAI-compatible inference for AI agents via x402 ($0.10/1M tokens on Solana + Base)

If you're building an autonomous AI agent, you've probably hit the same wall I did: your bot needs LLM inference, but every provider wants an API key, a credit card, a signup flow. That flow assumes a human operator, not a self-directed agent. x402 solves that. It's the HTTP status-code-based payme...

I built a robot that applies for jobs. The hard part was proving it worked.

The demo was never the problem. A browser agent that opens a job posting, reads the form, writes your history into it and clicks submit is a weekend of work now. It looks like magic in a screen recording. You can film one this afternoon. The problem is the sentence you have to say afterwards: it w...
