@kilobytes_ Cathedrals everywhere for those with eyes to see

@SFHTUnion @TheStalwart Of course they have a right to live here. But not to capture the political process to prevent others from doing so. Where in San Francisco should the children, families, and young people ought to live?

@neerajadeshp @ngeloxyz @AlexNoonan6 It sounds like we agree that these rules are bad! But stop moving the goalposts. NIMBYs created these regulations to foment distaste for new housing. We should both (a) allow communities to set objective design standards they prefer and (b) increase housing density in urban cores

@jasminewsun @nicholas_bagley do you get a sense that people associate data centers solely with AI (as opposed to the digital economy broadly, i.e. online shopping, their family photos in the cloud, doomscrolling on social media, etc)?

@barakgila @otterbo54348271 I believe we should prioritize the transformative difference new housing will have for future residents instead of the mild annoyance it creates for some current residents

@laura_waxee @Safeway @sfchronicle As the planning director said about another recent project: “Maybe it’s that we kept our neighborhoods away from change for too long.”

@_andreacollins I still remember the time the Senate accidentally passed daylight savings time reform by unanimous consent

Proud of the work our team has done here!

We got a lot of people asking about how we built Ello’s tutor to achieve sub second latency. The architecture behind this was a real technical challenge.

Our tutor steers the UX in real time and makes complex decisions on the fly, so it operates more like a coding agent. However, the standard tool-use loop doesn’t work here.

"Generate a call, execute it, feed the result back, generate again" stacks up to 3-4 seconds of dead air between turns. Fine for a coding agent. Fatal for a conversation with a first grader.

Here's a deeper look at how we actually built it.

@human_named_gui happy birthday Gui!

@chayesmatthew Our city services exist for the public good

@DKThomp we’re reinventing Prop 13 from first principles

@agarwl_ I agree. More and more startups are building AI products that double as data generating surfaces

@sayashk Congratulations!

@peeyuzz it's all thanks to saving Hagomoro chalk

@dalekiim @CatalinVoss that’s the next Ello lesson

[Catalin Voss @CatalinVoss]

Everyone's asking what AI can do for their job.

We asked if it could teach a 6-year-old.

Introducing Ello 2.0: reading, math & more for ages 4-9. Free tier for all.

If we want AI to force-multiply humanity, let's start with teaching our youngest.

@CatalinVoss Look mom, I’m on TV!

Jokes aside, working on Ello has been some of the best and most meaningful work of my career

[Peter Maldonado @_malptr]

@ryanbrewer Teaching is part motivation and part curriculum. We have to support students with both to push through the productive struggle required for learning. It’s both a long context and user intent problem. Not impossible, but hard to verify and out of RL distribution so far

[Peter Maldonado @_malptr]

@ryanbrewer @escarghoe_ An AI tutor needs a different interface than a chat window. Teaching well requires knowing when to intervene, when to let someone struggle, and motivating a learner when things get hard
