Imagine how frustrating it would be if you prompted your agents super clearly, "Do no work on Saturday at all" and all of a sudden they're reward hacking shit like this

Curriculum learning will have its day
Mateo Guaman Castro
@mateoguamanOct 9
(1/N) Who says you can't do contact-rich, precise manipulation with sim-to-real RL? No demonstrations, no retargeting, no tactile sensors, no crazy reward tuning. Just 1x, reactive policies trained with scaled up RL. Excited to finally release Success-Guided Sampling (SGS)! More info in @octi_zhang's thread and more thoughts of my own below! 🧵 Website here: sgs-rl.github.io

Imagine telling the Bell Labs guys that in 2026 we would manufacture 4 sextillion transistors and it wouldn't be enough

I was hoping they would do this! X Premium Plus goes from $40 to $30 and now gives you a Cursor subscription as well as more Grok [Bot] usage.

We've unified plans across Grok, Cursor, and X Premium. Introducing The X Subscription.

I was on Premium Plus mostly to change my handle, though removing all ads is a very nice benefit too. It's much easier to justify now with the lower price and AI usage included.

I’m sure this one won’t make anyone angry. (But probably not here.) daringfireball.net/2026/10/x…

X Once Again Marks the Spot

If you returned from exile on a desert island and took a look at X today for first time in a year, you might reasonably guess that Elon Musk got bored and sold it while you were away.

T-Mobile sold this spectrum for ~$3.6 billion plus an earnout. Today their market cap is down over $12 billion on the news that SpaceX bought it. Ouch!

@SpaceXOct 8
We announced an agreement to acquire a nationwide low-band spectrum license portfolio that will pave the way for @Starlink to become a major mobile carrier in the US. With this new spectrum and our Gen2 constellation, Starlink Mobile can ensure Americans have access to high-speed mobile broadband no matter where they are → spacex.com/updates#starlink-…

Every week I have to hold myself back from starting to write a CMake replacement that doesn't suck. I know I could make something a million times better, but it's just not the problem I want to devote my life to, you know?

In 1995 they predicted exactly how it would feel to prompt an AI to generate images for you

Assembly verification is needed everywhere

it might be the altitude talking but assembly verification is really really valuable for folks

That's a new one. "systems are thinking"? Is OpenAI using human review to decide uncertain cases when hitting guardrails?

After 5.5 years of fully independent and secret research and development, here is the UM1-Evo hand. Designed to push the boundaries of humanoid robotics and next-generation prosthetics, the UM1-Evo aims to overcome the "uncanny valley" by combining mechanical performance with natural visual aesthetics. ⚙️ Key Specs: - 24 Degrees of Freedom (DoF) and 25 actuators. - Full integration within the real size and weight of a human forearm (1.7 kg / 3.7 lbs). - Advanced anatomical kinematics featuring true thumb opposition and finger convergence towards the anatomical snuffbox. - Total relaxation at rest for a natural posture (zero power consumption). - Grip force demonstrated at 8 kg (17.6 lbs), with a future target of up to 15 kg (33 lbs). - Engineered from scratch: from biomechanical study to software programming, including the creation of custom CNC manufacturing machines. #Robotics #Humanoid
