If you’ve ever walked around San Francisco, you’ve probably seen these big heart statues - like Butterflight on Union Square. ❤️🗿🌁

There are 100+ of them all over the city. Read on for a few I saw on recent city walks.

I wrote about the Hearts in San Francisco public art project before, which places large heart-shaped statues all over San Francisco.

Today we saw two more of them on Union Square:
* Double Delight–Michael Osborne
* There is no try–Lawrence Noble

🌁🗽🇳🇱 SF and NYC are featured heavily - so if you live in either, you’ll see your city through a new lens. And of course, lots of Netherlands too :)

The updated 10th-anniversary edition adds over 100 pages - but gets a bit political.

🏙️ Book Review: Walkable City by Jeff Speck

“How Downtown Can Save America, One Step at a Time.”

Loved this deep dive into what makes a city thrive through walkability, bikeability, and smart planning. Lots of data﹠anecdotes make it a compelling yet easy read.

The Firebase documentation now contains a full list of which API key permissions it requires for each product. This is really handy if you want to lock down your API keys to your specific project needs.

The *last* one?

We're typically only a few, but I've had it with up to 6 people too.

We often see some folks don't dial in at all or do dial in and stay muted. When they then speak (and wave for the laptop they think is the central microphone), I just tell them to unmute - and nod encouragingly :)

Still no reason to hide it that well, Kevin. :-p

j/k: thanks for helping surface cool features. 👏

I did *not* know about this feature.

I use the unsubscribe button in the email subject line in gmail regularly, but never knew there's an overview of all subscriptions.

That might mean that it's quite well hidden. 😅

Hmm... It's been quite good for our team. All-but-one of us turns off their speaker volume (the last one turns it way up). But all microphones stay on all the time.

This new Google Meet feature is called Adaptive Audio, and it's seriously a 🤯 level change to the usability. No more audio feedback loops (ever?)!

🎙️ Are multiple attendees joining your Google Meet call from the same room?

They can now all stay unmuted, and Meet auto-selects the best microphone for each speaker. It's cool to note quality difference when it switches microphones, but also easy to get used to.

It's like being transported back to the '60s both with the music and the styling. Great attention to detail, so: explore!

Look at that: Brasa Bros on the corner of South Van Ness and 21st in the Mission will (some may say: finally) open tomorrow!

The food looks delicious, and the sidewalk setup they were testing today also looks fun.

I also had to think of this older article that I was re-reading today.

There's something really cool about being able to have so much condensed knowledge in your lap/on your desk.

> I have a coding project where I use the Firebase Realtime Database. Each child node under “path” has a property “timestamp” with the unix timestamp in millseconds. Write a Node.js script to delete all child nodes that are older than 2 days.

Oooh... that *does* sound cool!

Can you ask it to write a Node.js script to delete expired nodes from Firebase (full prompt in next reply and in the link) and see if it spits out a variant of the code from my Stack Overflow answers?

El Techo is gone, but not forgotten. 🏙️ The iconic San Francisco Mission rooftop bar now lives on as Cubita, a Cuban-inspired bar by the same team. Think rum cocktails, empanadas, cubano sandwiches, and rooftop views. 🍹🌆
