Celebrating 7 years of happy marriage at the temple for the goddess of wisdom.

Happy Mother's Day!

I just met with President Emmanuel Macron in Paris to discuss new rules and regulations for the internet. We both believe governments should take a more active role around important issues like balancing expression and safety, privacy and data portability, and preventing election interference -- reflecting their own traditions of free speech. Last year we invited French government officials to look at how we manage harmful content on our platforms. Our systems now proactively identify 65% of the hate speech we take down before it’s even reported -- up from 24% a year ago. But there are nuanced decisions to make here, such as how we should handle content that isn’t illegal but might cause harm. This is an area where I believe companies should not make these decisions by themselves and there should be a public process with democratically elected governments. Today the French government shared their recommendations for a new model that sets guidelines around what’s considered harmful. This would create a more consistent approach across the industry and ensure companies are held accountable for enforcing our standards against this content. While I am sure we won’t agree on everything, it’s important to get this right -- people use lots of different online services and the internet should be one platform that everyone can access on the same terms. This is our first official collaboration on regulation with a government, and we’re hopeful this process could work for other countries. Thank you to President Macron for hosting us and for your leadership on these important issues.

Today at F8, I talked about how we're starting to build out a privacy-focused social platform. For the last 15 years, we've built Facebook and Instagram into digital equivalents of the town square, where you can interact with lots of people at once. Now we're focused on building the digital equivalent of the living room, where you can interact in all the ways you'd want privately -- from messaging and stories to secure payments and more. To bring this vision to life, we're building Messenger and WhatsApp into platforms for all kinds of private interactions and working on making end-to-end encryption the default for both. We've redesigned Facebook to make communities as central as friends. We've added new ways to buy things securely on Instagram. Augmented and virtual reality also create more personal and intimate experiences -- so we’re bringing WhatsApp to Portal, adding end-to-end encryption for all calls, and launching Portal internationally. And I'm very excited that this year we're shipping Oculus Rift S and Oculus Quest, the headset that gives you full freedom of movement with no cables. As we build more of our services around this privacy vision, we're also changing how we run our company. We're committed to consulting with experts on the major tradeoffs and social issues to find the best path forward, taking a more active role in making sure developers use our tools in good ways, and building out the technical infrastructure to support this vision. This is going to take time and we don't have all the answers yet, but we're focused on getting this right and doing it openly. I’m looking forward to sharing more with you as we continue on this journey to build a private social platform.

Being a mom is hard, and since we've had kids Priscilla has had a hard time sleeping through the night. She'll wake up and check the time on her phone to see if the kids might wake up soon, but then knowing the time stresses her out and she can't fall back asleep. So I worked on building her what I call the "sleep box". It sits on her nightstand, and between the hours of 6-7am it emits a very faint light -- visible enough that if she sees it she'll know it's an okay time for one of us to get the kids, but faint enough that the light won't wake her up if she's still sleeping. And since it doesn't show the time, if she wakes up in the middle of the night, she knows to just go back to sleep without having to worry about what time it is. So far this has worked better than I expected and she can now sleep through the night. As an engineer, building a device to help my partner sleep better is one of the best ways I can think of to express my love and gratitude. A bunch of my friends have told me they'd want something like this, so I'm putting this out there in case another entrepreneur wants to run with this and build sleep boxes for more people!

Schnitzel for days.

Happy birthday Beast, you wonderful crazy dog.

Here's to a great 2019!

I'm thankful for time with family, and that all the girls went along with my plan for matching pajamas.

Tonight we hosted the Breakthrough Prize to honor the top scientific achievements in physics, mathematics, and life sciences. @lupitanyongo and I presented the Life Sciences award to Xiaowei Zhuang for developing a new imaging technique and discovering hidden structures that make up our cells. Until now, these complex molecular structures were beyond the resolution limits of traditional microscopy. Research by two other of tonight’s honorees has led to a new understanding of how materials can conduct electricity, which could lead to huge energy efficiency savings and potentially be used in quantum computing — helping to speed up the pace of tools used for critical applications like medical research, climate forecasting, and artificial intelligence. It’s achievements like these that will move society forward for everyone. Congratulations again to all the awardees!

We hope you had a spooky Halloween!

Priscilla's challenge: run a 30 minute 5k before I run a 20 minute 5k.

Max's first running race. Priscilla ran the Stanford 5K for Heart Health (and got a new personal record!) Then the kids all dressed up as super heroes and ran 200 meters. It was chaos.

Happy 4th of July! Celebrating by taking Max on a long kayak ride and teaching her about freedom.

Today I met with President Macron in Paris. We had a great conversation about France as an innovation center for Europe -- given the strong engineering talent here and culture of entrepreneurship. We've seen this first hand with our major artificial intelligence lab and our Startup Garage at Station F here in Paris. They are both doing incredibly interesting work -- and it's why we will continue to invest in France in the years ahead. Thank you to President Macron for hosting me.

A nice night for a walk.

One dog. Two daughters. Three teams trying to build a better world. Four nieces and nephews. Five kid-free days to celebrate. Six years of happy marriage.

When your child can now make you breakfast (sort of). Happy Mother's Day!

Our first family seder. Happy Passover and Easter this weekend!

Today is Sheryl's 10 year anniversary of joining Facebook. At this point, it's hard to imagine Facebook without Sheryl. I always say it's never just one person leading a company -- it's a team. I know we face many difficult challenges, but there’s no one I trust more to work through this with. Sheryl, thank you for being such a great friend and partner, and for everything you do to bring the world closer together. Here’s to the next decade.

Baking hamentashen. Chag sameach!

新年快乐! Happy New Year!

Lunch date with my valentine.

First day of preschool. They grow up so quickly.

I'm going on parental leave for December to be with August and Max, so you'll hear from me a little less. We have a couple more Facebook and philanthropy announcements this year and then I'll see you all in 2018!

It was an honor to thank this group of veterans in person on the last stop of my Year of Travel. Thank you to all who have served.

Inspired by the Dreamers I met in Oklahoma City. A good reminder that we need to pass the Dream Act before the end of this year.

It's an honor to host Taoiseach Leo Varadkar T.D. at Facebook. It's inspiring to meet a new generation of world leaders recently elected as heads of state in countries around the world. Ireland is an important part of our global community. Dublin is where our international HQ is located and our Clonee Data Center will be one of the most advanced in the world -- and powered by 100% renewable energy.

Taking these little wild things out to trick or treat for the first time.

Today we're celebrating Javier Olivan's 10 year anniversary of joining Facebook! Javi has been one of the most influential people in Facebook's history. Javi, thank you for being a great friend and partner, and for everything you do to bring the world closer together.
