** TRAVEL BAN FOR NYC ** All bridges, highways, and streets will be closed to traffic from 9pm Sunday thru noon Monday. No cars, trucks, scooters, or e-bikes. Limited exemptions for essential and emergency movement. This is projected to be NYC’s worst blizzard in a decade, with extremely dangerous conditions. Please take this seriously. Stay home if at all possible.

@bernhardsson I’ve seen them around downtown Brooklyn too. They are highly aggressive, invasive pioneer plants that thrive in disturbed, open areas. Impressive

I’m fascinated by these plants because their unique ecological niche seems to be construction sites in NYC where they are abundant and grow like 20 ft tall in a year. Never seen them anywhere else.

Private donations are now paying for the US military? What could go wrong? nytimes.com/2025/10/24/us/…

@AWSSupport I want to list all the EKS clusters in a project regardless of region. "gcloud container clusters list" will show something like the following. Notice the LOCATION column. No need to get all the regions then loop over each one.

Sorry you're having trouble, David. I'd like to forward this feedback internally, but I would need more details around this to do so. Please could you send me more info on this via DM? You can also ask this question on re:Post, so our community can engage with you there: go.aws/aws-repost. ^NR

One reason why I miss @googlecloud. To get all my GKE clusters in a project, I just run "gcloud --project X container clusters list". In AWS I have to run this abomination (fish shell) that requires a nested for-loop (once for regions, once for clusters). Is there a better way!?

for r in (aws ec2 describe-regions --query 'Regions[].RegionName' | jq -r .[]) echo $r for c in (aws --region $r eks list-clusters | jq -r .clusters[]) echo $c aws --region $r eks describe-cluster --name $c --query 'cluster.version' --output text echo; end; echo; end

to get off the wait list, especially if you're a * founder or key engineering decision maker at a company that's Series B+ or more than 10M in funding * current or prospective customer * someone interested in joining. We're hiring across the board! jobs.ashbyhq.com/modal?utm_sour…

Modal's Series B announcement party in NYC is tomorrow! We’re celebrating and excited to share it with our fellow builders in the city. This party’s invite-only. There'll be margs and merch. RSVP with link below then DM me partiful.com/e/5CvtfCR52jG2…

The best part about working on @modal is watching our customers literally build the future. Today, they’re using @modal for everything from generating AI music to powering real-world robots to curing cancer. And yet, this is just the beginning. We have so much more to build. If you like making computers do impossible things to solve user problems, please reach out. Especially if you are interested in low-level or large-scale systems, applied AI, GPU performance, delightful user experiences, security, or any combination of these.

It's true – @modal has raised a $87M Series B at a $1.1B valuation to advance the future of AI infrastructure.  Thank you to @Lux_Capital, @Redpoint, @AmplifyPartners, and others. Now more than ever, AI demands a complete reinvention of traditional compute infrastructure

We reverse-engineered Flash Attention 4.

I’m joining @modal to lead Product Marketing, and I couldn't be more excited. I’ve learned to go where the developer love is. Find that, and the rest will follow. That’s exactly why I was drawn to Modal. @bernhardsson and @akshat_b are building the tools that data and AI teams need, with a level of care and understanding that shines through in the product. I'm so pumped to tell this story 🚀

Excited for this event! Two companies pushing the edge of what’s possible with computing and Python. If you’ve used uv or ruff or Modal, you know what’s up. Come! luma.com/0s73i81b?tk=pH…

Please listen to this. open.spotify.com/episode/3OTsi2…

At @modal we've built every layer of the AI infra stack from scratch — from filesystems and networking to our own async queues and multi-cloud GPU orchestration. I sat down with @narayanarjun from @amplifypartners to go into depth on all of this, including the fun ways the Linux kernel has tried to stop us along the way:

Thanks to @raydistributed, @hsun_kai , and KubeRay maintainers for the nice gift for contributors.

> highlights include API server V2 and the Ray Autoscaler V2, both deliver improvements in reliability and observability over predecessors. v1.4 also introduces Service Level Indicator metrics, providing actionable insights into the health and performance of Ray clusters

KubeRay v1.4 is available. Happy to be part of an active, supportive open-source project and community. anyscale.com/blog/kuberay-v…
