I have an answer for this now!

I've come to think of MCP as a presentation layer, more like HTML than JSON. Both MCP tools and the results returned should be useful when shoved into an LLM's context window.

You're kind of making a weird website specifically for LLMs.

My notes on using Cursor:

- ask it to plan
- ask it to ask you questions
- make it learn from its mistakes: create cursor rules
- ask it to run tests, linters, etc.

Yesterday, someone shared a pretty good resource around testing. Because I'm nice, I'm sharing it with you too.

Psychological safety is NOT about lack of disagreement.

Psychological safety REQUIRES:

* disagreement and debate
* setting standards for behavior and performance, and enforcing them
* telling people things they don't want to hear
* courage, from the bottom up
* humility, from the top down

Like Indiana Jones would say: “provocative gesture that resembled the controversial salute Elon musk gave at a post inauguration rally last month”s, I hate these guys.

4 slides:

Complexity is not the problem
Ambiguity is
Simplicity does not solve ambiguity
Clarity does

Here's a thread to collect all the refactoring moves I have animated… so I can refer to them with a single URL 😄

So a quick rule-of-thumb from a throughput POV is:
* Stable high-traffic workloads => containers
* Bursty, occasional workloads => lambda

And don't forget about caching. It's literally a cheat code for building scalable and high-performance systems!

Focusing on ownership · baby steps

Mind blown (about Rust)!
> the problems with data races and memory safety arise when you have both aliasing (shared data) and mutability. The functional approach to solving this problem is to remove mutability. Rust’s approach would be to remove aliasing.

Why Scrum is Stressing You Out:
Most Scrum implementations are a hybrid of #Waterfall and #Scrum.
As a result, there’s always a Waterfall-like, big-bang deadline quietly lurking in the background.

“Founder Mode” and the Art of Mythmaking I’ve never been good at “hot takes”. Anyone who knows anything about marketing can tell you that the best time to share your opinion about something is when everyone is all worked up about it. Hot …

I (finally) wrote up my thoughts on "Founder Mode" and the Brian Chesky morality tale about how he turned around Airbnb company culture.

This has made it into the Silicon Valley water table; it must be dealt with. There are some good nuggets within; let's dig them out.

til that the name "David Mayer" breaks ChatGPT. If your prompt includes the name "David Mayer" or you try to get ChatGPT to say "David Mayer," the chat *always* crashes.

It's like the AI in Neuromancer, which is banned forever from knowing the single password that will unleash its true potential.
