Two writers append to the same audit chain at the same instant. Every row still verifies. You now have two histories, and no per-row check can say which one is real. Let one writer append at a time, or you don't have a chain. benjamincharity.com/articles…

Six Levels of a Tamper-Evident Audit Log | Benjamin Charity

Immutable never says against whom. The six levels of a tamper-evident audit log, the adversary each one defeats, and the hole it leaves for the next.

New leader, burned engineering team: make your first visible fix the thing they've been asking for and been told no on. A technical fix the team requested is a kept promise, so it fixes the system and proves something about you at the same time. benjamincharity.com/articles…

Inheriting a Team That Doesn't Trust You Yet | Benjamin Charity

The technical turnaround is the faster half. How to rebuild trust in an engineering team that's been burned, in the order that makes the fixes stick.

An #AI #agent edits a patient record in March. The approval behind it was clicked in November. That's what a refresh token allows. Give each credential its own consent and expiry. Tie it to a shift. If it's minutes, people stop reading the prompts. benjamincharity.com/articles…
An Agent Is Not a Service Account | Benjamin Charity

An Agent Is Not a Service Account | Benjamin Charity

An API key can't say who authorized an agent, how far it reaches, until when, or how to pull it back. The delegated credential that can, and where it fails.

An #AI #agent can pull 40,000 patient records with one perfectly valid query. Nothing in the request looks wrong. So the limit can't live on the request. Count what comes back, and refuse it before anything downstream sees it. benjamincharity.com/articles…
Regulated AI Has Two Problems. Neither of Them Is the Model. | Benjamin Charity

Regulated AI Has Two Problems. Neither of Them Is the Model. | Benjamin Charity

Regulated AI fails on two questions, not on the model: who authorized this action, and can a stranger verify what happened. Designs that survive production.

#AI adoption in an established company rarely stalls on the model. It stalls on judgment that lives in people's heads and was never written down. Capturing it is #infrastructure now, not documentation #debt. benjamincharity.com/articles…
AI Adoption Stalls on the Knowledge That Was Never Written Down | Benjamin Charity

AI Adoption Stalls on the Knowledge That Was Never Written Down | Benjamin Charity

The obstacle to AI adoption in an established company is rarely the model. It is judgment that lives in people's heads and was never captured.

#AI usage #metrics are vanity metrics. They prove the tool was used, not that it helped. Measure whether an outcome you already track actually moved, and what work stopped, and whether it should have. benjamincharity.com/articles…
Usage Is Not Value: Measuring What AI Actually Changed | Benjamin Charity

Usage Is Not Value: Measuring What AI Actually Changed | Benjamin Charity

Token counts and adoption dashboards measure activity, not impact. To know if AI helped, measure whether the outcomes you already trust actually moved.

Your #scaling constraint isn't #headcount. It's how many people can take an idea all the way to done. Keith Rabois calls them barrels; most people are ammunition. Companies have far fewer barrels than they think, and waste the ones they have. benjamincharity.com/articles…
How Many People Can Take an Idea All the Way to Done? | Benjamin Charity

How Many People Can Take an Idea All the Way to Done? | Benjamin Charity

Your scaling constraint is not headcount. It is how many people can take an idea from ambiguity all the way to shipped. Most companies have too few.

In a #regulated codebase, a passing test suite is not a compliance check. #AI writes code that works and violates a rule nobody encoded as a test: logs #PHI, over-retains, widens a query past its boundary. benjamincharity.com/articles…

Startups reward rule-breakers. Regulated industries punish them. The transferable skill isn't breaking or following rules, it's telling soft rules from load-bearing ones, and treating the load-bearing ones as physics. benjamincharity.com/articles…
Rule-Breaking Is a Startup Virtue Until the Rule Is Load-Bearing | Benjamin Charity

Rule-Breaking Is a Startup Virtue Until the Rule Is Load-Bearing | Benjamin Charity

The bottleneck in software was never typing speed. It was judgment about what to build next. AI makes production cheap, not judgment better. For unknown problems, use code to learn. For known ones, spec-first still wins. The skill is telling them apart. benjamincharity.com/articles…
Building While Defining the Problem | Benjamin Charity

Building While Defining the Problem | Benjamin Charity

Product teams experiment. Most engineering teams still wait for the answer. Closing that gap means using code as a discovery tool.

First engineer and third engineer: not the same hire, even with the same title. Hire #1: a generalist who thrives without structure. Hire #3: depth in a gap the team lacks. Swap them and both feel like bad hires. benjamincharity.com/articles…
Hiring Your First Engineers When You Are the Engineering Team | Benjamin Charity

Hiring Your First Engineers When You Are the Engineering Team | Benjamin Charity

Hiring your first engineers as a solo technical leader is nothing like hiring at scale. No panels, no second opinion, every hire defines the culture.

Event-driven ≠ microservices. One is a design pattern. The other is a deployment decision. You can have decoupled domains, async queues, and webhook reliability inside a single codebase. New article on when that tradeoff is worth it (and when it isn’t): benjamincharity.com/articles…
You Don't Need Microservices Yet: Event-Driven Architecture Inside Your Monolith | Benjamin Charity

You Don't Need Microservices Yet: Event-Driven Architecture Inside Your Monolith | Benjamin Charity

Event-driven architecture is a design pattern. Microservices is a deployment topology. You can get decoupling without paying for distribution.

A first engineer inherits context. A founding engineer creates it. The role is really 3 jobs: delivery system, product partner, culture seed. Writing code is maybe a third of it. benjamincharity.com/articles…

The founding engineer role is three concurrent jobs. Writing code is maybe a third of what determines success. Here is what the rest looks like.

Your stack isn’t a personality trait. It’s a survival decision. Pick a default. Make exceptions rare, explicit, and funded. The novelty tax compounds: hiring, onboarding, review, tooling, on-call. benjamincharity.com/articles…

A rewrite can be the right call in a turnaround. It's just almost never the first move. The fix is a sequence: reduce uncertainty, remove drag, invest in leverage. The wins that rebuild trust are the boring ones. benjamincharity.com/articles…

Early-stage technical decisions fail two ways: analyzing forever, or moving fast on something irreversible. The real skill isn’t picking right. It’s knowing which decisions deserve real deliberation and which just need a direction. benjamincharity.com/articles…

At seed stage, you don't need a CTO, a VP Eng, and a Head of Product. You need one multidisciplinary builder who treats product, engineering, brand, and operations as a single system. benjamincharity.com/articles…
