The Netherlands is a leader when it comes to food production due to innovations in agricultural techniques which improve efficiency. Growing a kg of tomatoes in the Netherlands uses 9.1 liters of water. The global average is over 210 liters of water per kg ow.ly/fGQn30nEJYM

Amazing to see the Nobel Prize being awarded to Geoff Hinton from UToronto, and John Hopfield from Caltech. Both are my alma maters and had the good fortune to work in their departments :) #DeepLearning #NobelPrize2024

Introducing Willow, our new state-of-the-art quantum computing chip with a breakthrough that can reduce errors exponentially as we scale up using more qubits, cracking a 30-year challenge in the field. In benchmark tests, Willow solved a standard computation in <5 mins that would

If you have been impressed by DeepSeek’s chain of thought reasoning, or the model’s introspection, you are about to be blown away by its multimodal reasoning capabilities. Introspection on text and images jointly is next level fascinating!

the most important issue that nobody has discussed about AI programming tools is Tabs vs Spaces. Almost all AI programming tools: o3-mini, copilot, cursor, etc use spaces for code indentation. Is the tabs vs spaces issue settled by AI then?

One weird quirk about the Geocoding system: "Null Island" at 0° latitude and longitude, is a spot in the Atlantic Ocean, where countless mapping errors default. It was once home to a real "Soul" weather buoy. This weather buoy got referenced so many times in error that it’s a

Experienced the Google Maps API woes both myself, and others, using it for Civics and census data. Skyrocketing costs from surprise bills and high usage fees, incomplete global coverage in rural areas, privacy risks with data tracking, and vendor lock-in. Time to ditch it for

Even in 2025, Monte Carlo dropout (keep dropout on at inference, 20–50 forward passes) remains one of the most effective ways to get calibrated epistemic uncertainty in remote sensing tasks. The original Gal & Ghahramani 2016 trick still beats many fancier methods for free,

Let’s look at the Ultimatum Game: I give you $100 and tell you to propose a split with a stranger. If they accept your offer, you both keep the cash. If they reject it, you both get $0. Pure economic theory says you should offer $1. The stranger should rationally accept, because

Loss aversion runs deep in the US housing market: homeowners expecting even a nominal loss are roughly 51% less likely to sell. These predictable behavioral frictions help explain why U.S. household mobility fell to a record-low 11.2% in 2024. AI modeling can now map these biases

It is rare for the Prime Minister of India to single out a private space mission. Mission Drishti : GalaxEye’s OptoSAR satellite, represents a meaningful step in India’s Earth observation capabilities. A natural point of comparison is Pixxel, India’s leading hyperspectral Earth

Sentinel-1D’s successful integration into the Copernicus constellation represents a solid reinforcement of Europe’s operational C-band SAR capability. Operating at approximately 693 km with modes delivering up to 250 km swath at ~5 m × 20 m resolution (IW) and 400 km at coarser
