I wonder if you can run a big model on a hundred phones

[Chris Pretorius @Teejip]

one day your phone won't install software it will just write them from scratch

[Chris Pretorius @Teejip]

@tunguz one day my phone will have 2tb ram

@PeterDiamandis I said SpaceX will be worth more than Earth if we achieve our goals.

Obviously true.

[Psychology Today @PsychToday]

What if the rarest form of intelligence isn't a high IQ at all? Some of the most creative minds excel at connecting ideas from completely different fields—a trait psychologists call integrative intelligence. Here's how it works. https://t.co/Ia8wis2JmS

a Fourier transform for instance has the same values of the origin in the limit, so just see the bottles as functions and other shapes are being approximated . the diameter of a bottle is round like a circle which composes a ft, interesting.

[Santiago @svpino]

These guys trained a robot with water bottles, and the robot learned to pick up other objects it had never practiced on.

They did this using reinforcement learning:

1. The robot had to pick a bottle out of a messy tote
2. Then it had to hand the bottle to a person
3. Only water bottles. Nothing else.

After they finished training, they tested the robot on different objects:

• On bottles, the success went from 80% to 98%
• On snack cans, the robot's throughput rose 40%
• On soft bags, the robot's performance improved by 13% even though they're deformable and much harder to handle than rigid objects.

Snack cans and soft bags have different shapes and weights, and the robot was never trained on them.

This was just one of three use cases they tested.

Every hour we spend teaching a robot costs a ton of money. If they only get better at handling the one object they practice on, reinforcement learning will never be worth doing.

But if the gains carry over, we could focus on teaching the hardest possible tasks and let the robot apply that knowledge elsewhere.

Here is the full write-up by @TheHumanoidAI on the infrastructure they used and what they learned:

Showing more content from people you follow has been one of the fixes.

The algorithm not barraging you with similar content due to a few likes is another.

This is histotripsy: focused ultrasound blasts destroy cancer cells mechanically in minutes, sparing healthy tissue completely.

Extremely excited to announce our first air-to-air kill of a flying moth by an autonomous micro-drone. This is a big step towards completely eradicating mosquitoes.

you have to know how to avoid deadlocks and that there may even be something like deadlocks. they may even happen in seemingly simple things like logging and that claude will forget about it. even fab fable

Why is Anthropic hiring Software Engineers? Why aren't they using agents with loops to do all of this?
