*Sincere* apologies to everyone impacted by outages of Facebook powered services right now. We are experiencing networking issues and teams are working as fast as possible to debug and restore as fast as possible

Nobody can predict what is going to happen over the next 12 months but we haven't had a real bad tech downturn since 2000 (2008 terrible for lots of other folks but nbd for tech) let me tell you what starting a company in 2000 was like..

Facebook services coming back online now - may take some time to get to 100%. To every small and large business, family, and individual who depends on us, I'm sorry.

Here’s our new computer vision system achieving state of the art results in image segmentation, without needing any labeled training data. This new model was trained on random, unlabeled data, but quickly achieved state-of-the-art results. It’s awesome.

Only in Silicon Valley: conversation at lunch veers into programming handles and memory management in 1990s era MacOS - person at next table leans over and says “I wrote the memory manager for that macOS” 😂

Basic internet math for @elonmusk's claim load time in India is 20s because of 1200 RPC calls (v.s. 2s in US): Bangalore->SF is ~250ms 1200 *.25s = 5 minutes! Way off!! 20s load time = MAX of 80 sequential calls Reality is likely 5-10? 1200 is happing inside datacenter?

I was told ~1200 RPCs independently by several engineers at Twitter, which matches # of microservices. The ex-employee is wrong. Same app in US takes ~2 secs to refresh (too long), but ~20 secs in India, due to bad batching/verbose comms. Actually useful data transferred is low.

Our new AI system learned speech recognition in English with *zero* speech to text training data: researchers just gave it lots of audio, and it figured out what the words were. But it goes way beyond that - it learned Swahili too!

Maybe my favorite AI generated video so far. Prompt: "A fluffy baby sloth with an orange knitted hat trying to figure out a laptop, close up, highly detailed, studio lighting, screen reflecting in its eye.mp4" killer work @MetaAI !!

I have no idea if now is going to be the same, better, or worse than the 2000s crash. But bad times can last multiple years and if you can make decisions now that extend your runway that’s probably the right call

I sat between Sheryl and Mark for over 13 years and worked closely with her through all the highs and lows at Facebook/Meta, so let me share a few of the important bits that people need to know about her:

Until you’ve been a founder or small business owner it is hard to describe the awful pit-in-the-stomach feeling of “if this doesn’t come through, I can’t make payroll.”

We bought one cisco switch from Webvan - who also happen to have been funded by Sequoia Capital. I made a joke to our new funders that they bought this switch twice. Was funnier in my head….

I was an exec at @mozilla when @Google decided that the browser was too critical to be run by a nonprofit they don’t control. Sounds a lot like @Microsoft and @OpenAI today. This is an unstable structure at its core. Hope all my friends over there are doing ok
