My book "100 Truths You Will Learn Too Late" is currently on a -37% off promotion. The idea is that you buy the book this week and read a chapter a day for the first 3.5 months of 2022.

Below, excerpts of the first few pages (I'll post more tomorrow)

Here are some reviews, by the way.

The reactions of many researchers on finally being held responsible for having read the very paper they submitted are... something. Image
“But Luca, the problem is that being excluded from uploading the PDF on one specific website is a major career blow”

A few “whys” asked by someone who thinks from first principles and hasn’t been conditioned yet to accept the status quo can open a can of worms.

5 ADVANCED CLAUDE CODE TIPS I'VE BEEN USING

1) Self-improvement injection

“Create a UserPromptSubmit hook (global settings). Script echoes: If 8+ tool calls, append one optimization hint (reusable skill, memory pattern, or workflow fix). One sentence. Skip if exploratory.”"
2) Skills audit

"Create a skill that lists all my installed skills (project & global level) with their line counts. Then ask the user which to review for improvement opportunities (conciseness, clarity, overlapping scopes, token efficiency).”
3) Claude audit

“Create a skill that reads all CLAUDE .md files and checks for: redundant instructions, verbose phrasing, and content that could move to memory. Present findings and ask if the user wants to implement them.”

Highlights from today’s Jeff Bezos’ talk in Turin 🇮🇹:

“Advice to young people: go work to a company where you can learn best practices”

I fully agree: it should also apply to politicians, educators, and other high-leverage roles.

1/N Image
“You can be an entrepreneur within a company; good companies don’t eject mavericks but empower them.”

I add: it’s so important to select a great first job and first boss; it’s sad it’s mostly left to chance, esp. comparing how much time is spent studying and how little interviewing.

3/ “It’s harder to be kind than to be clever.”

How to kill a country's education system, in 10 simple steps

1) Give teachers tenure, so bad ones can't be fired.

Also, do not train them on how to teach, and do not provide on-the-job coaching. Act as if education were important for students but not for teachers.

1/10
Make better students study longer so they spend their prime years out of the workforce and delay the compounding of job skills.

An excellent way to also lower fertility rates, by the way.

2/10
Introduce a massive conflict of interest by making the same institutions responsible for both education and certification.
