Towards a Harness That Can Do Anything

https://eardatasci.github.io/c/ambiance/harvey.jpg
I've been thinking about how to free LLMs from the chat pane for a few years now. Watching what people have tried and seeing what worked (and didn't), I've formed my own opinions on the right way to approach it. Here are my thoughts, and what I've been working on recently. II. Everything should be transparent so that the Agent can self-develop or heal (or audited postmortem). ...

The well-calibrated Bayesian [pdf]

Suppose that a forecaster sequentially assigns probabil ities to events. He is well calibrated if, for example, of those events to which he assigns a probability 30 percent, the long-run proportion that actually occurs turns out to be 30 percent. We prove a theorem to the effect that a coherent Bayesian expects to be well calibrated, and con sider its destructive implications for the theory ...

Show HN: I built a smart proxy so your coding agent can run loose

https://trollbridge.dev/og-card.png
Stuck choosing between approving every outbound request the agent makes — death by a thousand interruptions — or running it wide open and hoping it doesn't reach somewhere it shouldn't? Set the boundary once, then let the agent run freely inside the VM, container, or Incus instance you put it in. trollbridge is the HTTP proxy that gates outbound; you stay in the loop only for the ...

Bootstrapping GDC with DMD

FreeBSD does not have a package for GDC, the GNU D Compiler, which is the D frontend of GCC. I frequently use GDC on FreeBSD as a research tool. As such, I had to actually bootstrap GDC for FreeBSD. I forgot to share how I did it; this post is intended to fix that. It's very straightforward and easy. If you have DMD, then you can easily get GDC. I wrote a small wrapper program to make it ...
