"This is going to be the greatest next 10-20 years." @alighodsi

Sat down with arguably the most visionary entrepreneur of our time, @Databricks Founder/CEO, at @CalHacks in front of 3,400+ student engineers.

PSA: Databricks is tripling new-grad hires this year.

[Jeremy Fiance @jfiance]

I had the chance to host the keynote at @CalHacks last weekend with @alighodsi, Founder & CEO of @Databricks, in front of 3,400+ student engineers.

If there’s one thing the event proved, it’s that this generation was made for the AI era.

Databricks is tripling new-grad hires this year, and you could see why. Today’s engineers are building, shipping, and learning at a pace that matches the technology itself.

Ali’s message to the crowd: lean into that intensity.

Grateful to Ali for joining and to the Cal Hacks team for putting on an incredible event. You created something truly special for thousands of future builders!

Congrats to the winners of the Rox Tech Prize at Cal Hacks - @vardhans03 and @jpsingaraju 🏆

We challenged hackers to build AI agents powered by LLMs - systems designed to act autonomously on messy, real-world data

Their agent system that continuously monitors clinical trial protocols for regulatory compliance was fantastic!

[The Daily Californian @dailycal]

From Friday to Sunday, energy drinks, mattresses, computers and tech start-ups littered the floor and tables at the Palace of Fine Arts in San Francisco, where nearly 3,000 “hackers” competed in the 12th annual Cal Hacks, a three-day hackathon

Cal Hacks 12.0 was insane! I'm super proud of the whole team for pulling it off :D

We had 3.3k hackers and 700 projects were shipped - that's double last year's Cal Hacks!

Plus we did it all at the Palace of Fine Arts w/ great food, a silent disco, and beautiful designs.
