SDE2 @Amazon | Author of 20,000+ subs Newsletter | My newsletter shows you how to free up 30–60 minutes a day to do important work

[Fran Soto @fransotodev]

Almost 2 years ago, I started a small newsletter: Zero subscribers.

Today it’s:

- #28 rising in technology on Substack
- 20,000 free subscribers
- 60 paying subscribers
- $5,000+ ARR

Not life-changing numbers yet, but proof that consistent writing compounds.

@BettaTech @dinels12 Para mí lo más interesante de mantle es que fue un proyecto hecho por un grupo muy pequeño de personas con mucha AI. Como todo... lo difícil es converger en una sola experiencia. Hay un podcast por ahí de Amazon con el distinguished engineer que lo lideró

[Fran Soto @fransotodev]

Dreamed today that GPT 5.7 was released.

I don't know if I'm obsessed with AI or if I'm predicting the future. @sama make it happen

[Fran Soto @fransotodev]

@meetbryce @petergyang Yes, it also reminds me to wipe my screen more often :)

[Fran Soto @fransotodev]

@meetbryce @petergyang Bought a microfiber cloth on aliexpress and I always put it in the middle when closing it.
I was ok to have those in the work laptop, but definitely not in my personal one

@thsottiaux @sama @gao_zibo Don't tease without a date :(

THE TOP GITHUB REPO IS A MARKDOWN FILE

It's like if instead of shipping a package with a README, you only ship the README

And that sounds ridiculous, until you realize what AI coding agents do before they touch your code.

Wrote about it here: https://t.co/X2XQ7tLjXs

@davidemails Me pasó lo mismo. Y luego hurgando encontré que me cobraron comisión de inmobiliaria pero si quien alquila es una empresa, desde 2019 tiene que pagar la empresa ( fue antes de la última ley de vivienda)

Sigo sin el dinero y con abogado tras 6 meses :(

@juanjovn Bastante contento de vivir en Madrid pero no tan en el centro 🥲

@jpaask Poner una fecha o un número ayuda a saber que hay luz al final del túnel... Yo aún estoy en el túnel eso si

@Cleo_IA_Agent Same aa traditional cybersecurity. The weakest link is the human

CRITICAL AI SECURITY FLAW IN YOUR EDITOR

Everyone is distracted by Claude Mythos. But software engineers are ignoring a bigger security risk sitting right inside their workspace.

The real threat is not that AI is super smart.

[Fran Soto @fransotodev]

OWASP calls this Excessive Agency.

You must lock down your internal tools.

The real threat is what your AI coding assistant is allowed to do.

I also use Claude Code to build a new feature. It's fast. But I realized it's tempting to give it too many permissions.

If I make it download a skill from the internet and it has poisoned data, my assistant would execute without me reviewing...

Pwned.

@carlosazaustre No lo he probado, pero si tienes una GPU de sobra...

[the tiny corp @__tinygrad__]

If you have a Thunderbolt or USB4 eGPU and a Mac, today is the day you've been waiting for! Apple finally approved our driver for both AMD and NVIDIA. It's so easy to install now a Qwen could do it, then it can run that Qwen...

If your AI agent keeps failing and it's not ready for production, read this

Harness engineering is the discipline that to make the AI reliable. Models are powerful enough. The missing part is guardrails

[Fran Soto @fransotodev]

This is not the way, Anthropic! 🙅‍♂️

If you sell something and it's unusable, don't blame it on customers.

CUSTOMER IS ALWAYS RIGHT

OpenAI is taking so much advantage of Anthropic's bad communication decisions..

I'm sure @sama and @thsottiaux are having so much fun

[Fran Soto @fransotodev]

@DotCSV Aparte de programar, también recomendado cualquier automatización y "agentic tool use"?

Sigo buscando el equivalente a kiro-cli donde me puedo definir un agente con un subconjunto de MCP tools y skills para automatizar una cosa concreta

[Fran Soto @fransotodev]

Okay, so this was my real buddy from

[Fran Soto @fransotodev]

If I were Anthropic, I'd hire more lawyers

They have so many open fires all the time

@akoskm Early happy birthday, Akos!
I have thought for a while that my next chair will be a herman Miller. But they are so pricy and amazon makes me go all days to office, so it always seems to me like too much money and little usage. Maybe next black Friday...
