The Rabbit Hole Generator gave me Macaron this week, Oracle’s open-source tool for checking software supply chain security. My first instinct was to file it next to every other dependency scanner I’ve used: point it at a package, get a list of CVEs back. That’s not what it does, and the gap between those two things turned out to be the actual point. A vulnerability scanner answers “does this package version have a known CVE.” Macaron answers a different question: “was this artifact actually built from the source code we think it was, by a process we can verify, with evidence that isn’t just the vendor’s word for it.” Those sound similar. They aren’t. A package can have zero known CVEs and still have no evidence at all connecting the file you pip installed to the GitHub repo everyone assumes it came from. ...

Every post in this series starts the same way: I open Notion on a Friday and there’s a tool waiting for me that I didn’t pick. That’s on purpose, and it took me building an actual automation to get there. For a long time before this series existed, I was stuck in what I’d call zero learning mode. I like learning new things, genuinely, but I’d sit down with time set aside and just… not know what to point it at. Too many options, no filter, no momentum. I wasn’t short on curiosity, I was short on a starting point. So I built one: an n8n workflow that picks a tool for me every week, does the research, and hands me a scoped 30-minute exercise, no decision required on my end except whether to actually do it. ...

A signature on a piece of software proves someone with a key signed it. It doesn’t prove much about where that software actually came from: what source it was built from, what process built it, or whether anything happened to it between “code written” and “artifact shipped.” Provenance is the term for closing that gap: a verifiable record tying a specific commit, through a specific build process, to a specific output, in a way that’s checkable rather than just asserted. ...

Most incident response tooling forces a bad choice on you early in a case. Either you’re in a spreadsheet or a plain notebook with no structure, or you’re setting up a cloud platform with procurement friction, a rigid schema, and a data residency conversation before you’ve even confirmed the phishing email is real. Neither one matches the actual shape of early-stage IR work: messy notes, indicators that need pulling out and tracking, and relationships between them that you don’t know yet. ...

Most “agent frameworks” are libraries that push the hard parts of production—orchestration, secrets, versioning, and audit logging—into ad-hoc glue code. As teams move from “chatting with a PDF” to shipping internal copilots, the need for a governed, observable runtime becomes undeniable. This is where Dify enters the stack. It’s a self-hostable “LLM app runtime” designed to turn agentic prototypes into real business services. What is Dify used for in LLM application development? Dify is an open-source LLM application development platform that provides a unified workflow engine, model gateway, and RAG subsystem. It allows developers to model AI applications as explicit directed acyclic graphs (DAGs), enabling governed orchestration of LLM calls, external tools, and retrieval policies with built-in operational telemetry and multi-tenant isolation. ...
