I turned 23 Vanta RED tests GREEN in 14 days. Here is the exact command for each one.

The problem Vanta does not solve Vanta is excellent at telling you what is wrong. The dashboard is beautiful. The RED tests are clear. The remediation instructions are detailed. But Vanta does not fix anything. Every RED test represents a gap between the compliance requirement and your current infrastructure. Closing that gap requires someone to write a Kubernetes network policy, modif...

Technically interesting bits if you want to ...

Your LLM Bill Is 45% Too High. Here's the One Prompt Trick That Fixes It

Most developers ship AI features without looking at the bill. Then the bill arrives, and it's five figures. Here's the part nobody tells you: up to 45% of your tokens are pure fluff. Filler words, restated questions, "As an AI assistant...", apologies, repeated context. You're paying Claude and GPT to be polite. That stops today. The politeness tax Every LLM response is padded with t...

From Model to Product: Where AI Projects Actually Break

Most AI projects don’t fail in training.

Let's Encrypt short-lived certificates are quite strict, so you should use an ARI-capable client

Let's Encrypt short-lived certificates are much harder than they look if you think of them as just a shorter version of 90-day certificates. If you issue and renew multiple certificates for multiple subdomains in a short interval, you can hit certificate issuance rate limits more easily. Short-lived certificates increase the number of renewals, so these limits become much more visible. https://l...
