On Tyranny: Twenty Lessons from the Twentieth Century A historian of fascism offers a guide for surviving and…

I know it feels the world is going up in flames, and that you need a break instead of “lessons”. And you’re right.

But yet again this (short) book is what I‘d hope everyone in my country would read before voting.

Happened to be reading “Never split the difference” alongside “How to talk so kids will listen” and some of the advice is eerily similar.

I hope bath time doesn’t end soon end up sounding like hostage negotiations 😂

The Poet, the Physician and the Birth of the Modern Vampire From that famed night of ghost-stories in a Lake Geneva villa in 1816, as well as Frankenstein&#39;s monster, there arose that other great figure of 19th-century gothic fiction - the vampire - a creat...

Ok so Lord Byron was there when the modern vampire was born.

His “Childe Harold's Pilgrimage” also draws eerie similarities to “Childe Roland to the Dark Tower Came”…. which sparked the Dark Tower series, featuring, well, ‘Salem‘s Lot and Vampires abound.

Just Stephen King things man…

Great summary of why most GenAI predictions are off

> Building systems remains hard. Can I assume you’re familiar with Amdahl’s Law? That’s what’s going on: a massive speed up on a portion of the problem, but as that portion speeds up it becomes less and less of a contributor to the overall speedup

💯 agree

This take by Chip Huyen is what sold it for me.
How writing evolved from pigskin to press and Google Docs to abstract away the act of putting down ink to arranging and sharing ideas widely, LLMs can do the same for code

[5/5]

We’re not quite there yet with LLMs, which explains the current resistance from experienced SWEs. But if history is any guide, we almost certainly will be.

What a fascinating time to be alive!

- To see source files from a dependency, or to answer questions
  about a dependency, run `go mod download -json MODULE` and use
  the returned `Dir` path to read the files.

- Use `go doc foo.Bar` or `go doc -all foo` to read documentation
  for packages, types, functions, etc.

- Use `go run .` or `go run ./cmd/foo` instead of `go build` to
  run programs, to avoid leaving behind build artifacts.

Here are three lines from my AGENTS.md that make agents a lot better with Go.

Go has great CLI tools, but many people don't know about them, and so agents are not trained to reach for them.

Maybe the Go project should maintain a Go development skill?

Coincidentally there's a proposal from 2019 to add a -json flag to 'go doc' that could make it even easier for agents to use.

I've been trying to pick it up and bring it over the finish line!
