Fires, plumes, and wind shifts. Stay clear of the south flank of these fires in Nebraska, which will open up as the front surges through.

Using AI ethically: 6 tips for bringing AI tools into learning and work AI tools are everywhere. We offer several ethical considerations for how and when to use them.

6 tips, ahem, 6 reasons to just not use it cause it takes 6 times longer to consider all these things than to just do the real work yourself. its not about the answer its about the learning journey

overlooking a series of circular water filled tanks of a sewage treatment plant at night. 

lights line a long brick building on the horizon as a blue-black sky is stark behind a veil of thin puffy clouds in the distance.

good night, sewers.
good night, streams.
good night, operations and maintenance teams.
good night, settling tanks.
good night, stream banks.
good night, engineers, scientists, crews, managers, inspectors, analysts too.
a good night for us means serving with care.

good night, sewers, everywhere.

Another anniversary. 15 years ago today, the M9.1 Tohoku earthquake and tsunami swept through northeaster Honshu, sweeping away whole towns and killing almost 18,000 people. Five years later, this town of Otsuchi was still struggling with what to allow to be rebuilt.

It's finally out! 3 years after its release in French, my book on phage therapy, antibiotic infrastructure, and the possibility of pluribiotic medicine is now available! Thank you to @ColumbiaUP and to Vincent Lepinay, who has welcomed me into his collection!

Very happy to see "Pretending not to know reveals a capacity for model-based self-simulation", a collaboration with @chazfirestone.bsky.social and @ianbphillips.bsky.social, out in Psych. Science!

The shingles vaccine is incredible #learnsomethingnew #sciencefacts #vaccineswork TikTok video by Alex Falcone

This video is imparting genuinely amazing news about the shingles vaccine, but also contains a description of vaccines that made me laugh so hard I had to sit down. β€œWe inject the dead version so that when the live one shows up it knows we’ve killed before” is both accurate and SO FUCKING FUNNY

there is never a good time or place, said this critic. too much to do, not enough resources or time to do it.
but yeah, im with you. how we gather feedback and id problems or solutions or concepts of a solution is never easy. definitely a multisolving candidate though;

They built a system specifically for precision, so i agree. The irony is that, from a cost loss perspective the road to improving is higher pod first then tails into lower false alarms.

I think the social penalty is incurred only if there is no explanation. the social contract has to be renewed and renegotiated with our constituencies. warnings are a service not just a text product

Evidence to warn is overrated. Lead time is about taking chances and yes β€œover” warning. Imperfect observations, imperfect science …

Not sure we have a system for the tyrrany of the tiny or single storm, let alone design a precise one. But i think we can have a more robust approach.

Loud frog. Not a peeper, though the volume was still high from nearby peepers; this green fellow was calling out vigorously

Lunchercise brought me to these loud fellows. Two kingfishers, two pileated (same ones) and a host of small birbs were all very excited to be in nice wx.

Study Finds That Execs Are Outsourcing Their Thinking to AI The same class of business executives who heaped AI onto us by the shovelfull aren't immune to its effects.

Outsourcing their what now?

An LLM does not need to pull a trigger or automate a missile to serve the cause of war. It can work to make obscene violence feel justified and rational β€” to give you the illusion that you have β€œthought the matter through.” 🧡

Design agency price list displayed on black letterboard: ranging from 'WE DESIGN EVERYTHING' at 500 EUR to 'YOU DESIGN EVERYTHING' at 8000 EUR, with prices increasing based on client involvement. Shows ironic pricing structure where less designer involvement costs more.

Being close is all we should expect. Precision isnt the goal, just beyond our capability. and definitely a value add for estimating the worst case scenario
