#AI needs guardrails, #BDD is that guardrails. Just dropped sunny-side—a pure Common Lisp Gherkin parser and Behavior-Driven Development library! It cuts out external runtime dependencies and maps human-readable .feature files directly to Lisp macros, running test execution natively inside the […]

Ran the same function through six languages and a real tokenizer. Go: 50 tokens. Java: 59. Lisp, hand-golfed: 27. A language's grammar decides what every call site pays for, whether the reader or the model needs it or not. #foss #programming #ai dwightaspencer.com/posts/26-lisp-token-cost/

The most honest clanker in the room gets a gold star... And I quote: > The test "is this LLM language" applied by me to my own output has a structural flaw — I can't reliably detect my own patterns. > The honest answer is that this needs a human editing pass, not another LLM rewrite pass. You […]

mlisp alpha is out: packages for Linux, FreeBSD, and NetBSD. A mailing list manager where the Maildir is the database. No separate state to drift out of sync, the archive is the audit trail. CAN-SPAM, GDPR, and CASL compliance are test-covered code paths, not a checklist bolted on after the […]

96% of OT incidents originate in IT. An attacker with zero ICS knowledge, one commercial LLM, and access to the IT environment can now map industrial assets in a single session. The capability gap is the boundary with no monitoring. The vNode gateway was exposed. The session found it. #OT […]

Just caught @ThePrimeagen's video. geohot: "agents frontload progress but never achieve polish" Low performers using agents produce high-volume slop with no feedback loop to catch it. High performers use agents as multipliers and self-correct constantly. The layoff wave isn't AI replacing […]

NY Assembly Bill A2228 would require criminal background checks to buy a 3D printer "capable of creating firearms." The bill text is broad. "Capable of" is not defined. Most consumer FDM printers can print gun components. So can a milling machine. So can a lathe. This is infrastructure for […]
