Happy Independence Day 🇺🇸

From battlefields and memorials to parks and protected landscapes, the places cared for by the National Park Service help bring our shared history to life.

you either die a frontier lab or live long enough to see yourself sell compute

@inductionheads Chat has spaces so you could be in a room by yourself and assign todos.

When I was your age - I was perhaps of similar opinions, life teaches you that age is not a disqualifier, lack of curiosity is. Time will tell what is right, but in a market that is evolving fast, having a POV is important and being able to pivot is equally important. Many of the largest tech companies are run by us old guys :). Older perhaps, irrelevant - trying not to be.

[Rohit Jnagal @jnagal]

Need to try it out. Sounds very promising.

Apple just made Docker Desktop optional on Mac.

And it is completely free.

This is apple/container. 26.5k stars no Github.

You can now run Linux containers natively on your Mac without installing Docker Desktop, without a background daemon hogging your RAM, and without paying $21 a month per developer for a commercial license.

Here is what it does:

→ Runs Linux containers as lightweight VMs directly on Apple Silicon using macOS 26 virtualization
→ Fully OCI compatible. Pull any image from Docker Hub, GitHub Container Registry or anywhere else
→ Written in Swift and optimised specifically for Apple Silicon. Faster and lighter than anything Docker Desktop does on Mac
→ Standard container CLI syntax. If you know Docker commands you already know how to use this
→ Push images you build to any standard container registry and run them anywhere

Docker Desktop charges $21 per developer per month for commercial use. Apple's version costs nothing and ships as open source under Apache-2.0.

Microsoft made Docker Desktop optional on Windows with WSL Containers last month.

Apple just did the same on Mac.

Docker is not going anywhere. But the era of paying for a GUI wrapper around containers on your own machine is quietly ending.

Good lord this edit. Insane.

[Rohit Jnagal @jnagal]

My car is reminding me that I should be driving to Moscone this week.

Missing my people at Databricks and following all the awesome new announcements and product/project launches. ❤️

Silly and brilliant

NEW: malware developers added nuclear & biological weapons text to to their spyware.

Goal? To trigger LLM safety refusals... so that their spyware wouldn't be analyzed by an AI security scanner.

Cleanest practical example I can think of for why over-indexing on first order safety alignment is risky.

When closed (and open) models ship with aggressive refusals, they will be sprinkled with second-order blindspots that attackers will discover...and exploit.

We are only in the earliest days of attackers leveraging these features, and it wouldn't surprise me if users systems that need to handle complex cybersecurity issues demand that models be less safety-blunted.

In the weeds: @SocketSecurity's post also shows why intention matters in how you design a malware analysis pipeline to avoid prompt manipulation.

In This House We Believe
- AI will get better every year, forever (get used to it)
- self-improvement is possible, but never infinite
- discovery is only meaningful if it impacts human lives
- learning history helps avoid the hubris of the moment
- we are not all going to die

Five cancers that used to be death sentences. Pancreatic. Glioblastoma. Triple-negative breast. Renal. Melanoma. The median survival for metastatic pancreatic cancer is still 6 months. Glioblastoma, 15 months.

Now personalized mRNA vaccines are producing complete remissions in some of these patients. Not responses. Remissions.

BioNTech’s pancreatic cancer vaccine has 6-year follow-up data. 8 of 16 patients who mounted an immune response are still alive. For a cancer that kills 95% of patients within 5 years, that's incredible.

Topol’s pyramid here maps the trajectory. From broad checkpoint inhibitors at the base to personalized neoantigen vaccines at the peak. The technology is climbing.

[Sarvam @SarvamAI]

We are excited to announce that Sarvam is partnering with @PixxelSpace to power the AI backbone of India's first orbital data centre satellite.

This is a first for the country, with India-built AI models running on an India-built satellite and both training and inference happening directly in orbit, without any dependence on foreign cloud or ground infrastructure.

Compute is cool again. Hard, unsolved problems at unbelievable scale.

Thrilled to be back at Google building the next generation of AI infra. Incredible pace and innovation across chips, models, and products.

Loved my 3 whirlwind years at Databricks building and scaling the serverless platform. Great engineers and leaders—no stopping this enterprise AI rocketship. I’ll miss working with this crew.

Taking the weekend to reset and reflect before the next boarding call.

Replit now deploys directly to Databricks.

Your apps run inside your Databricks environment while inheriting its security, governance, and data access.

Beta is live. Enterprises are already building with it and seeing massive acceleration in BI and internal tools.

In 2023, Chinese researchers set out to create a 'pig depression model' — a way to reliably induce depression in pigs for medical research.

The researchers (Yang et al, 2023) confined pigs so tightly they couldn't move and left them in a dark environment without food or water for 24 hours.

It worked: the pigs exhibited anhedonia — an inability to experience pleasure — along with anxiety and reduced appetite. The researchers concluded they'd found a promising way to induce depression in pigs.

Their inspiration? Factory farms. They tried out the total restraint after noting that sows, confined in gestation crates and kept chronically hunger, "have been found to be in a depression-like state."

The main difference? After 24 hours, the researchers let the study pigs out. On factory farms they never do.

the bigger story may be what comes next.

Ghodi said it out loud: "With the sort of SaaS disruption that we’re seeing, Databricks will definitely partake in that disruption"

He has the data, the AI... and now he's building the apps. Its the AWS playbook for the AI age.
