People seem shocked that the author of Clean Code doesn't read code anymore. But that should not be surprising.
Why did I write Clean Code? What is the goal of keeping code clean? To get it out of the way of the real job -- thinking.

I can now probably say this:
Two months ago, inside Anthropic someone suggested building a token leaderboard.
A heated internal debate followed and the decision was made to *never* ever do it… because several people inside Anthropic simply thought ahead of the consequences
Sources: Amazon has shut down an internal leaderboard that tracked employees' use of AI tools after workers tried to boost their scores with needless tasks (@rafeuddin_ / Financial Times)

This works surprisingly well:
• Ask Claude Code to fix a bug
• Let it work and figure it out
When it finishes, use this prompt:
"Knowing everything you know now, delete your fix and implement a better|concise|elegant version."
Claude will use the first pass to explore and learn the problem. Sometimes, this will lead to suboptimal code.
The second pass will be better because Claude already knows the problem and can write a better solution.

This GitHub incident is insane. Merge queue commits have been reverting previously merged commits at random.
This not only breaks the mental contract teams have with Git in general, but is subtle enough to be really hard to unravel after the fact.

¡Vuelve DeepSeek! Han lanzado de código abierto la V4.
Versiones: Flash y Pro. Contexto de 1 millón de tokens.
No es el mejor modelo pero es...
¡20 veces más barato que Opus 4.7 y GPT 5.5!
Para muchos casos de uso va a ser más que suficiente:

ALT Captura de un tuit de DeepSeek anunciando “DeepSeek-V4”, supuestamente disponible y de código abierto, con contexto de 1M barato. Presenta dos modelos: DeepSeek-V4-Pro, con 1.6T parámetros totales y 49B activos, y DeepSeek-V4-Flash, con 284B totales y 13B activos. Termina invitando a probarlo en chat.deepseek.com mediante Modo Experto o Modo Instantáneo. Todo muy épico, como si el contexto de 1M viniera a salvarnos de copiar y pegar trozos de documentación como cavernícolas.

GStack is an open-source toolkit built by YC President & CEO @garrytan that turns Claude Code into an AI engineering team — with skills for office hours, design, code review, QA, and browser testing.
In this video, Garry walks through how GStack works, starting with Office Hours, a skill modeled after real YC partner sessions that pressure-tests your idea before you write a line of code. He demos it live, going from idea through adversarial review, design mockups, and automated QA in a single session.
Memory on Claude Managed Agents is now in public beta.
Your agents can now learn from every session, using an intelligence-optimized memory layer that balances performance with flexibility.
New in Claude Code: auto mode.
Instead of approving every file write and bash command, or skipping permissions entirely, auto mode lets Claude make permission decisions on your behalf.
Safeguards check each action before it runs.

Si quieres entender Big O Notation de una vez por todas, esta guía es una joya.
Ejemplos interactivos, diagramas claros y explicaciones sencillas.
En la universidad hubiera pagado por tener algo así.
Si te dedicas a programar, lo tienes que leer:

Scrum is a cancer.
I've been writing software for 25 years, and nothing renders a software team useless like Scrum does.
Some anecdotes:
1. They tried to convince me that Poker is a planning tool, not a game.
2. If you want to be more efficient, you must add process, not remove it. They had us attending the "ceremonies," a fancy name for a buttload of meetings: stand-ups, groomings, planning, retrospectives, and Scrum of Scrums. We spent more time talking than doing.
3. We prohibited laptops in meetings. We had to stand. We passed a ball around to keep everyone paying attention.
4. We spent more time estimating story points than writing software. Story points measure complexity, not time, but we had to decide how many story points fit in a sprint.
5. I had to use t-shirt sizes to estimate software.
6. We measured how much it cost to deliver one story point and then wrote contracts where clients paid for a package of "500 story points."
7. Management lost it when they found that 500 story points in one project weren't the same as 500 story points on another project. We had many meetings to fix this.
8. Imagine having a manager, a scrum master, a product owner, and a tech lead. You had to answer to all of them and none simultaneously.
9. We paid people who told us whether we were "burning down points" fast enough. Weren't story points about complexity instead of time? Never mind.
I believe in Agile, but this ain't agile.
We brought professional Scrum trainers. We paid people from our team to get certified. We tried Scrum this way and that other way. We spent years doing it.
The result was always the same: It didn't work.
Scrum is a cancer that will eat your development team. Scrum is not for developers; it's another tool for managers to feel they are in control.
But the best about Scrum are those who look you in the eye and tell you: "If it doesn't work for you, you are doing it wrong. Scrum is anything that works for your team."
Sure it is.

It's incredible how many tech teams still measure productivity with things like:
- # of PRs
- # of JIRA points
- Avg cycle time
- & other JIRA/Git metrics.
These data points help middle managers with spreadsheets & charts to show upwards.
They don't make your team deliver more!

My nr. 1 remote working tip:
Don't put one or more boxes of delicious cookies on your desk. They will, through the magic of async work I suppose, disappear.
