I'm in the process of rebuilding my homelab from the ground up, moving from a 24U full-size 4-post rack to a mini rack. One of the most difficult devices to downsize (especially economically) is a NAS. But as my needs have changed, I'm bucking the trend of all datahoarders and I need less storage than the 120 TB (80…
“These models somehow just generalize dramatically worse than people. It's a very fundamental thing.”
GitHub Actions has a package manager that ignores decades of supply chain security best practices: no lockfile, no integrity verification, no transitive pinning

An exploration of the evolution and meaning of the Forth programming language and its context in history.
While preparing for my Black Hat and DEF CON talks in July of this year, I found the most impactful Entra ID vulnerability that I will probably ever find. One that could have allowed me to compromise every Entra ID tenant in the world (except probably those in national cloud deployments). If you are an Entra ID admin…
In celebration of the std.Io introduction patchset landing today , here is the text version of a short, interactive demo I gave at Zigtoberfest 2025 .
Anthropic publish most of the system prompts for their chat models as part of their release notes. They recently shared the new prompts for both Claude Opus 4 and Claude …
A far more detailed explanation of prompt caching than anyone asked for: how tokens, embeddings, and attention make cached LLM tokens 10x cheaper and faster.
