Virtue Garnishes: The 3-Second Mental Hack That Short-Circuits Bad Habits
You’re about to send that email. The one where you “correct” that coworker’s suggestion with a snarky reply. Your fingers are already typing the passive-aggressive opener when something interrupts: you notice the tightness in your chest, the heat rising. You recognize it: a “whisper” as the Ledger of Life calls it. You jot down “w: […]
Rust CLIs with Clap
Types Define Interfaces Types are important. In fact, I’d guess that the expressive type system in rust is the single biggest reason why so many developers love the language. Types allow us to have a contract between parts of the system about our data and how to interact with it. All programming languages have the […]
The Email Startup Graveyard: Why 80%+ of Email Companies Fail
While countless email startups have burned through millions solving non-existent problems, we at Forward Email have quietly built actual email infrastructure from scratch since 2017—proving that sustainable email services require engineering, not just venture capital. This is an exhaustive analysis of email startup failures, acquisitions, and the fundamental misunderstanding of what email actually is. Warning […]
Claude Code now supports Hooks
Claude Code hooks are user-defined shell commands that execute at various points in Claude Code’s lifecycle. Hooks provide deterministic control over Claude Code’s behavior, ensuring certain actions always happen rather than relying on the LLM to choose to run them. Example use cases include: Notifications: Customize how you get notified when Claude Code is awaiting […]

Entropy of a Mixture
Entropy of a Mixture Given a pair (p0,p1)(p_0, p_1)(p0,p1) of probability density functions and an interpolation factor λ∈[0,1],lambda in [0, 1],λ∈[0,1], consider the mixture pλ=(1−λ)p0+λp1.p_lambda = (1 – lambda) p_0 + lambda p_1.pλ=(1−λ)p0+λp1. How does the entropy H(pλ)=−EX∼pλlnpλ(X)H(p_lambda) = -E_{X sim p_lambda} ln p_lambda(X)H(pλ)=−EX∼pλlnpλ(X) of this mixture vary as a function of λlambdaλ? The widget […]
The New Skill in AI Is Not Prompting, It’s Context Engineering
Context Engineering is new term gaining traction in the AI world. The conversation is shifting from “prompt engineering” to a broader, more powerful concept: Context Engineering. Tobi Lutke describes it as “the art of providing all the context for the task to be plausibly solvable by the LLM.” and he is right. With the rise […]
Senate GOP budget bill has little-noticed provision that could hurt your Wi-Fi
Michael Calabrese of New America’s Open Technology Institute told Ars that 6 GHz and CBRS “are the most vulnerable non-federal bands for reallocation and auction.” While the spectrum for auctions is to come from frequencies between 1.3 and 10.5 GHz, much of that spectrum will be off-limits either because it’s specifically excluded or because it would […]
