Has anyone figured out how to get the Duo Simulator to do the side-by-side app layout? I’d like to see how apps look next to another one (like Safari) and can’t see any way to get the Simulator to do this.

Mac and iOS developer at the Iconfactory, where he has worked on apps including Twitterrific and Tot. He writes about development at furbo.org.
Another bug with iOS 27.1: when your app launches in a partially folded state, the view’s traitCollection has a compact horizontal size class. If you close the Duo, and then open it partially, the horizontal size class is regular. This can lead to weird layouts when you launch an app in the partially folded state: only workaround is to close/open device again. Weirdly, auto layout constraints in a storyboard aren’t affected by this. It’s something in the UIViewController transition methods. Related

Last iPhone Duo observation for the day: Close/Done/Cancel buttons switch sides depending on if you’re in the left or right side-by-side layout. I get the “stay close to the thumbs” mantra that likely guided this decision. But it also moves the most important buttons around and presents the end user with an inconsistent layout. If someone gets used to an X button on the right and it’s suddenly on the left, does it do the same thing? A naive user may think it does not. Related
Another surprise: the closed (external screen) view has navigation on the right. But it can also be on the left in the side-by-side layout: Related

I find myself disagreeing with Terence Tao (a very scary phrase to say!) and think the core question posed is whether the "misalignment" is between the mathematical community and humanity. In other words - are the Millenium Prize problems meant to incentivize advancements for humanity or foster the field of mathematics and mathematicians? As a counter example, if there was a prize for creating a drug that cured a rare strain of cancer, we would not care if it was AI that did it. We would be happy it has been solved. On the other hand, if long running agents figured out the puzzle in "Kryptos"… AI alignment Related

RE: https://mastodon.social/@Mastodon/117117221397911074 After hearing feedback from people struggling with #Mastodon’s layout and navigation for a long time I’m really looking forward to these changes. And I’m really impressed with the work @imanijoy has put into researching user needs with surveys, interviews, and round tables. I feel like the community has never been so represented in the design process before. The screenshots are marked “in progress” for a reason though—it’s a process. Related

. @yurimilner was that world class investor. After one meeting he said he wanted to invest and asked me for a valuation. I threw out a number 10 pct below what i figured our next round would be. He said he would wire the money next week. I think it was $150m. Never asked for board seat or any terms. He ttly got what the founder of a high growth company cared about. No meetings. No terms. Dont bother us. Let us cook! Quoting @kevinleeme Whenever other founders ask me who my best investors are and who I’d recommend they work with, I name the handful of VCs who rarely bother us and trust us to operate. It’s funny how simply doing nothing as an investor can put you in the top 1% of a founder’s book. Related

So, a deployment of your agent uh in the real world generates data. That data then grounds the simulator and makes it more realistic. The simulator generates harder edge cases for the critic to score and for the agent to learn from.

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public

Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked

are left in their original language.
