Build a humanoid robot yourself! 🪚
OpenArm is an open-source humanoid robot.
It comes with full CAD, control code, firmware, and simulation tools, everything needed to build, modify, and operate it.
The arms are designed to be compliant and backdrivable. Teleoperation is supported, with force feedback and real-time gravity compensation so operators can guide the arm naturally.
Super important, on the simulation side, OpenArm works with platforms like MuJoCo and Isaac Sim, letting developers test policies in virtual environments before running on hardware.
Assemble it yourself from a kit or get it prebuilt, the goal is accessibility for research labs, small teams, and enthusiasts.
The project is run by @enactic_ai in Tokyo, Japan, and aims to lower the barrier for experimenting with dexterous manipulation.
Let's put robotics in mainstream! 🔥🔥

there will be no field jobs left. only field machines. 🙂
Cross-country remote-cabin operation of construction machinery has already been done in China.
Some claims to have done from 2,000 km away, with end-to-end control delay under 30 ms.
We're publishing our most detailed threat intelligence report to date.
It covers how people tried to misuse Claude—for cyberattacks, influence operations, surveillance, biology, and building weapons—and how we found and stopped them.
We disrupted every operation in the report, and used the lessons from them to strengthen our safeguards. Where appropriate, we also shared what we found with authorities and other AI companies.
These cases are not typical: we’re highlighting some of the most sophisticated misuse we’ve seen. But they’re especially important to discuss, because they show us where AI misuse is headed, where our safeguards work, and where they need to improve.
We’re publishing this report so others can spot the same activity on their own platforms, and so we can give the public a clearer view of how emerging threats develop.

questions i got today at @lennysan's summit and how i answered them:
Q: How is Notion evolving and positioning itself nowadays?
A: We've always been known to be your second brain - that is more important now than ever as AI needs context. We really want to make Notion the second brain for individuals and their teams regardless of what tools and harnesses folks want to use.
Q: What if my team is already comfortable in the tools their using and don't want to learn a new tool?
A: Thanks to Notion's extensibility, whether that's MCP, API, or SDKs, you really don't need to touch Notion to use it. You can work wherever you want and have Notion live as the brain/context for those tools and workflows.
Q: How do you see organizations really benefitting from using Notion?
A: Notion's value really becomes exponential when you start thinking about the amount of tools Notion can help your team replace. Notion can be the homepage for your company for docs, wikis, meeting notes, project management, etc. Having one place for everything makes people much more productive.
Q: What if I have data that exists outside of Notion? How can Notion be my second brain and context layer if it doesn't have everything in it?
A: You can bring whatever data into and out of Notion with our new developer platform at https://t.co/RgxLk5BVfE. Notion doesn't need to be your CRM but it can bring your CRM into Notion for example.
Q: What are you most excited about with upcoming Notion releases?
A: CUSTOM VIEWS! Finally you can build whatever view you want for your Notion data. You want Obsidian graph view in Notion? Don't wait for us to build it - you can build it yourself now. Currently in beta!
Q: My son/daughter is in high school. How can Notion be helpful for them?
A: I started using Notion in college. It was really helpful for me to track all my notes and homework assignments. It was super helpful once I started applying for internships and jobs to track all the conversations I'm having. You can imagine how helpful this will be once a high schooler starts needing to track college applications.
Now everyone can put data to work.
We’re introducing a new Data agent in ChatGPT Work so you can turn your company’s data into answers, interactive dashboards, and action—just by asking.
Just add the Data Plugin in ChatGPT Work, connect to the data sources and context you already use, and start the conversation. https://t.co/EG1nQFZfEU
