Built a thing I've started living in recently, and open sourced it: https://t.co/d71zAdCU17

My interaction with agents has moved mostly into docs. They write them, we discuss, they edit and on and on. Sometimes they build what's in the doc, other times the doc is what ships.

And thanks to Thariq and the Claude Code team, these docs are now beautiful html.

But I didn't have an easy way to
- give feedback on specific parts
- ask questions about a paragraph
- ask it to simplify something
- or add more detail (collapsible sections in html are chef's kiss)

Redline lets you leave comments in html docs, and lets agents read those comments and reply as they edit the doc.

Runs locally, state stored in your html files, easily checked into your repo. No db, no 3rd party server, nothing.

It was fun building Redline - I was the user and the builder simultaneously. Literally was giving stream-of-conscious feedback to Codex (sometimes Claude Code) in one window while using the app with another CC instance as we worked on a fairly complex doc.

@signulll disagree. the future is path-dependent.

sprinkling AI is obviously dumb, but it’s also possible to overshoot

The secret to investing is to invest in unstoppable people building inevitable things.

[Umang Jaipuria @umang]

@iamtolux why is that a bottleneck?

[Umang Jaipuria @umang]

seeing much about how product management is important again, because when you can build anything, deciding what to build is important.

this is upside-down logic on two counts:

- deciding what to build is important when building is hard, not when its easy
(there are other things that become more important)

- roles are a bundle of responsibilities, and no role's bundle will survive the impact with AI. you cannot talk about the future of product management without unbundling it first.

Kudos to bchesky and daniellurie.

SF should feel like Florence during the Rennaisance, Constantinople of the Byzantines, Babylon of Nebuchadnezzar, the Timurid Samarkand, Paris during Belle Epoque, the Khmer’s Angkor, Athens of Pericles, the Ptolemaic Alexandria…

Today, I stood with Airbnb co-founder and CEO Brian Chesky to announce his $100 million gift to San Francisco’s parks. This is the largest single-donor gift to the city in San Francisco’s history, and will support the development of new parks, upgrades to existing spaces, expanded hours at recreation facilities, and much more. 

An initial $39 million will help unlock five projects in neighborhoods across our city. SoMa, the Mission, Bayview-Hunters Point, Potrero Hill, and downtown will all see transformational projects finish sooner, bringing more welcoming public spaces to residents across San Francisco. 

As Mayor, one of my top priorities is making San Francisco a city where families can put down roots and build their futures. Earlier this year, we launched our Family Opportunity Agenda—a citywide effort to bring down the cost of living and expand economic mobility for San Francisco families. 

We're building more housing, protecting tenants, expanding access to affordable childcare, and keeping public transportation safe, reliable, and affordable. We're also investing in the public spaces families rely on every day. 

Our parks are an essential part of what makes San Francisco such a special place to raise a family. Our recreation programs provide exceptional and affordable opportunities for San Francisco families. With this investment, we're bringing those opportunities to more neighborhoods across our city, expanding access to recreation, and making our parks even better for the families who use them. 

San Francisco has created enormous opportunity for the people who have built their businesses here. And with that success comes a responsibility to give back to the city that helped make it possible. So, my ask to every leader who sees what Brian has done today is simple: help us create more opportunities for the people who call San Francisco home. Now is the time. Our city is coming back. Don’t just watch it from the sidelines. Be a part of it.

two possible reasons for this:
- lack of will
- lack of state capacity

Diwali night pushed Delhi into a pollution nightmare, with an Air Quality Index hitting an insane 2,518.

Firecrackers blanketed the capital in thick, toxic smog, raising serious health alarms.

@floydophone Ahhh, sorry to hear. Saw some report that measured traffic impact and claimed there was none. Obviously personal experience trumps that.

Curious, what might explain the pink areas right next to the highway? Property prices?

[Umang Jaipuria @umang]

It’s the same people - they really must not like nice things.

This quote from Rob Delaney is the perfect response to the viral Seth Rogen clip about how much happier he is than his friends with kids. Not because one is better than the other (there are a million ways to be happy or miserable, and people should do what they want!), but because it's true that while the things that are hard about parenting are easily imaginable, the joys are pretty unknowable until you're in it. I say this a recently happy childless and now happy childful (2+ months) person.

"Whenever someone tells me they’re expecting their first baby and they’re nervous, I tell them the following: “Oh my goodness, that’s wonderful. I am so happy for you. Listen, of course you’re nervous but here’s the deal: you’re ready for all the bad stuff. You’ve been very tired before. You’ve been in pain before. You’ve been worried about money before. You’ve felt like an incapable moron before. So you’ll be fine with the difficult parts! You’re already a pro. What you’re NOT ready for is the wonderful parts. NOTHING can prepare you for how amazing this will be. There is no practice for that. There is no warm-up version. You are about to know joy that will blow your fucking mind apart. Happiness before this? HA HA. Mystery? LOL. Wonder? Fuck off! You are about to see something magical and new that you have no map for! None! This is it. Are you ready for that? Are you? No! No, you’re not!"
