They list Anthropic as one of their customers and appear to have conducted penetration testing for them previously, so they're likely one of those trusted organizations.

Clawforce is an open-source control plane for managing Clawbot agent teams.

Deploy a team of agents in a few clicks. Configure characters, skills, MCP integrations, and tools through a UI. Agents can plan, coordinate, and execute tasks collaboratively.

Includes per-agent controls: runtimes (process, Docker, k8s), tool approvals, and permissions.

New comment by xuancanh in "Yann LeCun to depart Meta and launch AI startup focused on 'world models'"

xuancanh — Wed, 12 Nov 2025 09:32:23 +0000

Meta did exactly that, kept him but reduced his scope. Did the broader research community benefit from his research? Absolutely. But did Meta achieve a good outcome? Probably not.

If you follow LeCun on social media, you can see that the way FAIR’s results are assessed is very narrow-minded and still follows the academic mindset. He mentioned that his research is evaluated by: "Research evaluation is a difficult task because the product impact may occur years (sometimes decades) after the work. For that reason, evaluation must often rely on the collective opinion of the research community through proxies such as publications, citations, invited talks, awards, etc."

But as an industry researcher, he should know how his research fits with the company vision and be able to assess that easily. If the company's vision is to be the leader in AI, then as of now, he seems to have failed that objective, even though he has been at Meta for more than 10 years.

In industry research, someone in a chief position like LeCun should know how to balance long-term research with short-term projects. However, for whatever reason, he consistently shows hostility toward LLMs and engineering projects, even though Llama and PyTorch are two of the most influential projects from Meta AI. His attitude doesn’t really match what is expected from a Chief position at a product company like Facebook. When Llama 4 got criticized, he distanced himself from the project, stating that he only leads FAIR and that the project falls under a different organization. That kind of attitude doesn’t seem suitable for the face of AI at the company. It's not a surprise that Zuck tried to demote him.

> It was strange to me that there was no log-as-service with the qualities that make it suitable for building higher-level systems like durable execution

There are several services like that, but they are mostly kept behind the scene as a competitive advantage when building distributed systems. AWS uses it behind the scene for many services, as mentioned here by Marc Brooker https://brooker.co.za/blog/2024/04/25/memorydb.html. Facebook has similar systems like LogDevice https://logdevice.io/, and recently Delos https://research.facebook.com/publications/log-structured-pr...

New comment by xuancanh in "Amazon Aurora DSQL"

xuancanh — Wed, 04 Dec 2024 18:11:47 +0000

My guess is from the customer's perspective, DSQL seems to have too many limitations, making it feel more like an enhanced version of a NoSQL database with SQL semantics, ACID transactions, and multi-region capabilities rather than a truly distributed version of a relational database. It seems the DSQL team doesn't fully understand why relational databases remain widely popular today. What makes them great is their flexibility, which lets them handle all kinds of use cases and adapt as things change. But all the limits on transaction size, column size, etc.., and too many missing capabilities pretty much take away all the big advantages relational databases usually offer.

The limit is for query operations, not just transactions.

AWS tends to prioritize performance and scalability over functionality, which is reflected in the design of DynamoDB, SimpleDB, and now DSQL. I'm also not a big fan of this style. It doesn't give customers the flexibility to choose their own trade-offs like Spanner does and assumes that customers can't make these kinds of decisions on their own.

xuancanh — Wed, 14 Aug 2024 23:29:25 +0000

It's because of the way most companies build their status dashboards. There are usually at least 2 dashboards, one internal dashboard and one external dashboard. The internal dashboard is the actual monitoring dashboard, where it will be hooked up with other monitoring data sources. The external status dashboard is just for customer communication. Only after the outage/degradation is confirmed internally, then the external dashboard will be updated to avoid flaky monitors and alerts. It will also affect SLAs so it needs multiple levels of approval to change the status, that's why there are some delays.

What he said is true, AWS uses Rust heavily in some of AWS core systems https://aws.amazon.com/blogs/devops/why-aws-is-the-best-plac....

Some of the open source projects you can find are AWS Firecracker https://github.com/firecracker-microvm/firecracker and Cloudflare Pingora https://github.com/cloudflare/pingora
