Working on AI for Tableau Pulse Discover has been a journey - full of surprises, challenges, and real insights about how people actually use data. The limits of AI for analytics. I wrote a bit about that here:

A new simulation lets the Milky Way blossom star-by-star, 100 billion points of light weaving themselves through time with the help of an AI surrogate. Computational mycelium, able to grow whole galaxies in silico, revealing patterns we could never see by hand across deep time.
The simulated Milky Way: 100 billion stars using 7 million CPU cores
Researchers have successfully performed the world's first Milky Way simulation that accurately represents more than 100 billion individual stars over the course of 10 thousand years. This feat was acc...

The twin probes just launched toward Mars have an Easter egg on board
Two twin spacecraft are on their way to study the effects of space weather on the planet Mars, adorned by “easter eggs” including a couple of kiwis.

The decline and fall of stars in the Universe
The cosmic star-formation rate rose and rose for billions of years, peaking about 10-11 billion years ago.
Today, it's slowed to a trickle, and someday, will cease altogether.

The decline and fall of stars in the Universe
For over 10 billion years, the cosmic star-formation rate has been dropping and dropping. Someday, the final star in the Universe will die.

I was reading that after 48 years, the Z80 microprocessor finally ended production in 2024. An 8-bit superstar that powered arcade cabinets, homebrew dreams, and whole eras of computing. Hard to believe a chip from 1976 outlived so many of its successors. 🤯 #trs80

3I/ATLAS is the first interstellar object bright enough for amateurs to image: so fabulous to see the delight ☄️😍
I got it... I actually got it... Interstellar comet 3i, imaged from the middle of light-polluted Kendal, at 6am this morning, using my Seestar S50... This comet was already billions of years old before our Sun was even *born*... Very chuffed with this!

Derided today, BASIC’s strange, free-form jumping system helped inspire the movement to remove GOTO from most languages > a kind of mythic serpent whose chaos taught civilization to build walls.

Japan once dreamed of a winged craft called HOPE, a spaceplane meant to slip from orbit and land like a thought returning to Earth.
But the Cold War thawed, budgets cooled, and the vision dissolved like spores in sunlight.

Europe once built a mockup for a 3-seat spaceplane called Hermes. It could’ve launched on Ariane 5 and glided home like a mini-Shuttle. Then politics killed it.

Randall’s idea is that a thin, unseen disk of dark matter periodically tugs the Solar System as we oscillate through the Galaxy, shaking loose comets from the Oort Cloud and sending extinction-level barrages toward Earth like a cosmic metronome of catastrophe.

🛰️ The new ESA deep space dish features a cryogenically cooled signal amplifier chilled to around -260 °C (≈ 13 K noise temp) to slash thermal noise and boost sensitivity. With that ultra-cold LNA, the station can pick up signals far weaker than a cellphone transmission from Mars.

How does the Very Large Telescope in Chile keeps its vision razor-sharp? Each 8.2-m slowly loses reflectivity to Atacama dust. Engineers clean them with CO₂ “snow,” but every 18 months the 23-tonne mirror is trucked to a facility, stripped of old aluminium, and given a fresh 80-nanometre coating.
