Always fascinated with traffic light countdown in Amap in China. Turns out it is implemented by crowdsourcing motion data. Had thought they had integration with city govs (which they do but with just a small number of cities). What is Google doing with maps all these years?

Our internal LLM tool, built last March, allows Stripes to safely experiment with LLMs. With 3K Stripes using the tool weekly and over 700 shared prompts, the tool is reshaping how we work and build for our users. We shared more with @bentossell
How do you get your team to use AI? I gathered insights from Stripe, Google, Intercom, Zapier, Adobe and others and came up with 9 ways they help encourage employee adoption. - AI champions - Demos & workshops - Small experiments, cross-functional teams - Hackathons - Internal

8 years after my start date at Uber, I am calling dibs on recounting the tale of DIBS, drawing inspiration from Matt Basta’s captivating piece titled No sacred masterpieces. https://t.co/fkAPHiNew7

I joined Uber in October 2015 to work on the brand-new Driver Incentives Backend System. Jonah Cohen, my soon-to-be manager, called dibs on naming it DIBS just a few weeks before I arrived. Fast...

Summer time means I am going to help quite a few new grads to ramp up. Over the last few years I learned a few hacks to make the process more effective. In this post I describe the spin-up buddy setup, and some admin task tricks like the Slack user group.

I wrote a post to argue that leadership is not a title, but a skill. I referred to Tom Brady as an example of true leadership. It is too bad that Brady, as @patrickc would say, is not going to make a few more slam dunks in Super Bowl LVI later today. https://t.co/OajzGuchhl
