Clarificador el artículo de The ecomodernist: El cambio climático por sí solo no explica los incendios forestales actuales.
Los cambios en el uso del suelo, la acumulación de material combustible, y las políticas de extinción de incendios influyen enormemente en la propagación. breakthroughjournal.org/p/cl…

Esto es importante en la etapa de tener hijos. La gente relaciona ambición con éxito profesional. La ambición aplica a toda actividad que quieras realizar.
Gran parte por la que la gente no disfruta tener hijos es la obsesión (que no ambición) con la carrera (de la rata). Tienes niños y sigues ofuscado en que te promocionen, o levantar más pasta o comprarte el coche más rojo que el del vecino.
Más allá de si tiene sentido eso o no, apárcalo para más tarde. Ya tendrás tiempo de currar como un loco en otra etapa. Acabas de tener niños, enfócate en ello. Esto no es una carrera lineal. Son etapas, disfruta cada una de ellas.
Para hacer algo bien tiene que ser tu único foco. No puedes tener 2 focos. Y menos 3. Si estás montando una familia como puedes justificar que la promo es mayor foco que tu hijo de 3 años?
I think ambitious people should treat life in “seasons” rather than trying to balance everything every day.
A few years massively overallocated to work. A period getting seriously fit. A year or two nomading. Then family takes priority for a while. Then maybe at 35 you go completely insane again and spend four years building a new company, and so on.
The mistake is thinking every metric needs to stay green all the time. Most great outcomes (building a company, writing sth serious, training for an event) need uninterrupted runs, not daily moderation. Sometimes work should suffer cause you’re travelling, sometimes your social life should suffer cause you’re building, sometimes career progression should slow cause family matters more. That’s fine.
And tbh it probably makes life more fun too. You get actual chapters and completely different versions of yourself instead of spending 40 years maintaining the same perfectly optimised routine. A few intense years in one city, a weird nomad phase, an obsession that takes over your life, then something completely different. Probably much more memorable than one very long well-optimised Tuesday.
It's why I encourage everyone to think of balance in years, not days. A good life can look horribly unbalanced on some random Tuesday and still be very balanced over 10 years.

I'm Italian. My wife is Chinese, born in Beijing.
Many of you have asked how to visit China for the first time. So we sat down and prepared this 101: which cities, in what order, and how to do a first trip properly.
We are both international. She studied in the US and worked in Hong Kong, then Europe. I've lived in more countries than I can count. We know well what most of you will look for in this trip: this is the advice we give our closest friends.
The short version: start with Beijing and Shanghai, leave Shenzhen for a second trip, and don't treat China as a one-week destination. And mind the weather: avoid peak summer and peak winter.
The good news: you are going to luxury you have probably never seen, better than Dubai, at a fraction of the cost.

How to climb all 4 layers of Claude in one weekend:
(even if you just signed up yesterday)
✦ Level 1: Claude Chat (Saturday morning)
Go to claude .com/download. Install the app.
Pay the $20. Select Opus 4.6 + Extended Thinking.
Connect Slack, Drive, Notion through Connectors.
Stop writing long prompts. Prompt this instead:
"I want to [TASK] for [SUCCESS CRITERIA]. Use AskUserQuestion before you start."
Most people stay here forever.
You're leaving 90% of Claude untouched.
Claude Basics: how-to-claude.ai.
——
✦ Level 2: Claude Cowork (Saturday afternoon)
Go to 'Cowork'. Create a folder "Claude-Cowork."
4 subfolders. About me, template, project & outputs
Create about-me .md: what you do, how you do.
Create anti-ai-style .md: words you'd never say.
Set Global Instructions (Settings → Cowork → Edit):
"Always read my files first, never edit my originals, deliver everything to CLAUDE OUTPUTS."
You just killed prompting.
From now on, your prompt is 2 lines + your folder.
Move on to Cowork: claude-co.work
——
✦ Level 3: Skills + Plugins (Sunday morning)
Open Cowork. Type: "Use the skill-creator to help me build a skill for [your most repeated task]."
Claude interviews you. Answer and be specific.
It generates a SKILL .md. Test it: "When would you use this skill?" If the description is vague, fix it.
Upload: Settings → Capabilities → Skills → Upload.
Now it fires automatically. No slash command.
Install Plugins: Cowork > Customize > Browse plugin
Skills with about-me .md. Skill handles the process.
Voice file handles tone. Two layers simultaneously.
Set up Claude Skills: nitter.gq/rubenhassid/status/203…
——
✦ Level 4: Code + Computer (Sunday afternoon)
Click the Code tab. Create a folder. Connect GitHub
(free account → Settings → Connectors).
Prompt: "Create a GitHub repo named [project]. Code everything. Don't ask for permissions."
Download VS Code. Install the Claude extension.
Turn on "Skip Permissions" to go 100x faster.
After your session, paste this: "Create a CLAUDE .md file with everything you learned about this project." Now Claude remembers your fonts, colors, and structure forever.
Claude code guide: claudecode.free
Claude Computer: Settings → Desktop app → turn on Browser use + Computer use.
Connect your phone with Dispatch. Text a task.
Schedule a recurring task: left sidebar → Scheduled → write the prompt → pick the frequency.
Claude Computer: nitter.gq/rubenhassid/status/203…
This is where you stop working inside Claude.
Claude starts working on your computer.
——
Saturday, you were prompting like it's ChatGPT.
Sunday, Claude is running your screen, building your website, & sending you text updates.
That's all 4 layers. In one weekend.

The eclipse from Orion.
On April 6, external cameras attached to the Orion spacecraft's solar array wings captured the Moon backlit by the Sun during a solar eclipse.
ALT The Moon, backlit by the Sun during a solar eclipse, is photographed by NASA\u2019s Orion spacecraft. Orion is visible in the foreground on the left. Earth is reflecting sunlight at the left edge of the Moon, which is slightly brighter than the rest of the disk. The bright spot visible just below the Moon\u2019s bottom right edge is Saturn. Beyond that, the bright spot at the right edge of the image is Mars. Credit: NASA

Un analista enviado al estrecho de Ormuz con 15.000$, un Xiaomi, un equipo de grabación oculta y un paquete de puros cubanos tumba el precio del barril del petróleo un -5,7%. 👇
- Firma un acuerdo en la frontera de Omán prometiendo no recopilar información. Lo ignora.
- Se sube a una lancha sin GPS con un desconocido, se mete en el Estrecho de Ormuz mientras sobrevuelan drones y llega a 18 millas de la costa iraní.
- Se da un baño en el mar mientras se fuma un puro.
- La Guardia Costera lo detiene y le confisca el teléfono.
- Consigue volver a casa y escribe un artículo para contar todo lo que vio.
Lo que descubrió este analista de @citrini cambia todo el análisis de Wall Street:
Los barcos apagan el GPS y falsean destinos → los datos “oficiales” no los cuentan → Wall Street cree que hay poco tráfico → Wall Street cree que el estrecho está cerrado → el precio del petróleo sube más de lo que debería
Los datos que usan todos los hedge funds para valorar el riesgo en Ormuz tienen un punto ciego del 50%:
Irán tiene 29 petroleros cargados moviéndose con transponders apagados. Han movido 3B$ en crudo hacia Malasia desde que empezó la guerra.
Los generales retirados en la CNBC, los analistas de satélite y los traders de Bloomberg están mirando la mitad del tablero. Un tío en una lancha con un Xiaomi y unos cigarros ha obtenido mejor información que todos ellos.
El precio del barril de petróleo cae de 115,50$ a 108,90$ en unas horas.

Honestly, this is the most accurate diagram I've seen.
Waterfall: You plan for 18 months and deliver exactly what nobody needs anymore.
Agile: You deliver something usable at every step, but the CEO keeps asking, "Where's the car?"
AI: You get the car on day one. It has six wheels, the doors are on backwards, and it has a rocket launcher. You spend more time making it yours than actually "building"; it's shaping. owning. verifying. That's what the best AI developers do now. They don't build. They shape and own.

British Airways. Lufthansa. Swiss. Austrian. Air France. KLM. Cathay Pacific. Singapore Airlines. Finnair. Virgin Atlantic. All suspended flights to Dubai. The busiest airport in the Middle East is running on Emirates, Etihad, and hope.
The suspensions are not symbolic. British Airways has cancelled all flights to Dubai, Abu Dhabi, Amman, Bahrain, Doha, and Tel Aviv, with Abu Dhabi routes suspended into later this year. Lufthansa Group, covering Lufthansa, Austrian, Swiss, and Brussels Airlines, suspended Dubai and Abu Dhabi until at least mid-March with rolling extensions. KLM cancelled Dubai until 28 March. Cathay Pacific until 31 March. Finnair until 29 March. Singapore Airlines until at least mid-March. Every carrier cites the same three words: airspace, insurance, safety.
The insurance is the mechanism. War-risk premiums for Gulf airspace surged 300 to 1,000%, and no airline’s risk committee will authorise a route where the premium assumes a drone can reach the fuel supply and the fuel supply just proved it can be reached. Hours ago, the Dubai Media Office confirmed a drone incident near DXB that set a fuel tank on fire. Civil Defence contained it. No injuries. But the fire is not the problem. The fire is the evidence that the risk committees used to justify the cancellations, and the evidence just updated in real time.
DXB processed 95.2 million passengers in 2025. It connected 260 destinations across six continents. It was the physical proof that the Gulf was open, safe, and central to global aviation. Seventeen days of war have reduced it to a hub running limited schedules on its home carriers while every major international airline that made it the world’s busiest routes its passengers through Istanbul, Doha, and Singapore instead.
Emirates and Etihad are operating limited services and gradually resuming. They have no choice. DXB and Abu Dhabi are their homes. But a hub is not defined by its home carriers. It is defined by the international network that feeds it. British Airways feeding London passengers through Dubai is what makes DXB a global hub rather than a regional airport. Cathay Pacific feeding Hong Kong. Singapore Airlines feeding Southeast Asia. Lufthansa feeding Frankfurt. When those carriers leave, the hub becomes a terminal with runways and a fuel tank that was on fire this morning.
The suspensions are temporary. Every airline says so. Every statement includes “pending airspace stabilisation” and “subject to review.” But temporary in aviation means something specific: it means the route remains cancelled until the insurance market reprices the risk below the threshold at which the route generates positive margin. The insurance market will not reprice the risk until the war ends. The war shows no sign of ending. Araghchi told CBS “as long as it takes.” The insurance cancellations are not temporary. They are indefinite with a euphemism attached.
The tourism economy that lost $600 million per day was calculated when the airlines were merely cautious. The DFM Real Estate Index that fell 30% was calculated when the airport was merely disrupted. The fuel tank fire converts “disrupted” into “targeted.” And targeted airports do not attract the 95.2 million passengers who made DXB the world’s busiest. They attract the insurance adjusters who calculate whether the airport can reopen at premiums anyone will pay.
Dubai built its economy on connectivity. The airlines that provided the connectivity have left. The fuel tank that powered the connectivity is on fire. And the war that caused both is being fought by a regime that says it will last as long as it takes, funded by an economic empire of 812 companies that no bomb has touched.

JUST IN: A drone just hit a fuel tank at the busiest airport in the Middle East. The Dubai Media Office confirmed it 23 minutes ago.
“A drone incident in the vicinity of Dubai International Airport (DXB) affected one of the fuel tanks. Dubai Civil Defence teams are currently working to bring the fire under control. No injuries have been reported so far.”
That is the official statement from @DXBMediaOffice, posted in English and Arabic, with thousands of views in the first half hour. The fuel tank is burning. Civil Defence is on scene. The airport that processed 87 million passengers last year, the global hub that connects 260 destinations across six continents, the physical embodiment of everything Dubai built over three decades, has a fuel tank on fire because a drone that costs less than a business-class seat through Terminal 3 reached the aviation fuel supply that keeps the hub operational.
This is the third confirmed drone incident at or near DXB since the war began. On 11 March, two drones struck near the airport, injuring four people. On 1 March, drones hit AWS data centres in the same corridor. Today, the target was not a server farm or a residential tower. It was aviation fuel. The escalation is vertical: from data to shelter to the liquid that makes the airport function.
Fuel tanks at international airports are not incidental targets. They are the circulatory system of aviation. DXB operates on jet fuel stored in tank farms adjacent to the runways. A sustained fire in a fuel tank does not merely delay flights. It grounds the refuelling infrastructure that determines whether aircraft depart at all. Civil Defence is containing this fire. The question is not whether this fire is contained. The question is whether the next drone reaches the next tank, and whether the insurance market, the airline route planners, and the 87 million annual passengers calculate that a 94% interception rate over an airport fuel farm is sufficient assurance to book the ticket.
The cumulative toll on the UAE since 28 February: 294 ballistic missiles, 15 cruise missiles, over 1,600 drones. Six dead. 141 injured. AWS data centres struck. Creek Harbour and 23 Marina towers burning from debris. The Burj Al Arab facade hit. Jebel Ali Port targeted. Fujairah oil zone fires. The Iranian Hospital closed. Five schools shuttered. Twenty-one people charged for filming. And now a fuel tank at the airport that defines the city burning while Civil Defence teams work to contain what the air defence system intercepted everywhere except here.
The $600 million daily regional tourism loss was calculated before a fuel tank at DXB caught fire. The DFM Real Estate Index was down 21.4% before a fuel tank at DXB caught fire. The $20 billion DFC insurance facility had zero confirmed takers before a fuel tank at DXB caught fire. Every metric of economic damage that existed this morning is now being recalculated against a new data point: the airport itself is no longer outside the target set.
Dubai built the busiest airport in the Middle East to prove the Gulf was open for business. Iran just proved it is open for drones. The fuel tank is burning. Civil Defence is responding. No injuries reported. And somewhere in the Gulf, a Shahed that cost $20,000 to $35,000 just imposed a repricing event on an aviation hub worth hundreds of billions by reaching the one target that converts a “drone incident” from a security event into an infrastructure crisis: the fuel that keeps the planes flying.

Don't ruminate, activate.
I find it is difficult to think my way into a better mood. When I sit and stew, the problem usually grows larger in my mind.
But if I activate — even if it's unrelated to the problem at hand — my mood tends to improve. Action breaks the spell. Move your body, go outside, play an instrument, work in a different room, do something.
Movement changes your state. And when your state changes, your perspective changes. New solutions appear. You notice options that were invisible when your mind was stuck running the same loop.
