[Anam Hira @anamhira]

At Uber, one bug reaching production could cost millions in a single day.

So quality was solved with headcount. Rooms of people would manually tap through the app before every release.

Request a ride, add a card, cancel a trip, in 50+ languages, release after release.

Now coding agents have increased the throughput of changes by an order of magnitude. A room of people can't keep up anymore. Nobody can.

Here we used Revyl to run those same flows on Ubert (demo uber), sending our mobile use agent through the app on a cloud iOS device. Every step verified, with CPU, network, and state traces attached when something breaks.

What took a room of testers hours per release runs in 16 minutes, asynchronously.

Get started with our free trial and put an agent on your own app.

X has quietly launched its complete rewrite of X Web, starting with Logged-Out pages

Built with Tanstack Router and Tailwind, which brings in SSR Streaming, Vite, Rolldown, ES Modules, etc all the modern web practices

Congrats to the @Engineering Web team for pulling this off!

i dick tate everything now, not just ai related tasks

Sometimes I leave out context and just sit and watch the agents struggle. Reminds them who's still in charge.

@wamweaaa Grill-me? I found large tasks to be less accurate than doing small focused passes.

Here's something fun I've been thinking about.

Agents like eve are increasingly just files.

The shadcn registry is a protocol for distributing files.

could the registry be the distribution model agents need?

[Sam Lambert @samlambert]

Doing good engineering with AI still requires craft. The distribution of engineering ability remains unchanged.

I left IT for a trade. For several reasons, (AI was one of them but not the most pressing one).

1) I like AI. I have 12 apps in the app store right now. They are being used, (231 installs last week). But I can see the writing on the wall. IT jobs are not going away completely...

Your entire life will change when you realize that anything above zero compounds. That showing up consistently matters more than showing up perfectly. That small things become big things. Never allow optimal to get in the way of beneficial.

Envy and resent act as a dominant negatives on your ability to be inspired. Protect that ability at all costs.

Tip: prevent scrollbars from re-wrapping text.

Using "scrollbar-gutter: stable" fixes this

[rahul @0interestrates]

if you’re still writing loops that prompt coding agents you’re falling behind. you need to build a meta agent that infers what loops you would have wanted based on your vibe and then write those loops

Kitambo kidogo in my sheep era I thought Vision 2030 was about development.

Then I noticed every project that got finished tracks you, identifies you, or bills you.

Alafu zile meant to serve us, kina hospitals, schools, water stay incomplete.
