I LOVE custom tools in sketchpad (didn't play with Cabri as much, but huge respect for them as well)

I absolutely love this from @prospect.org. Worth a read (and a subscribe!) prospect.org/2026/04/06/w...

totally makes sense to me to want sliders at the top -- I wonder if there's a feature focused just on that, especially since sliders are so tall

really like this idea! challenge becomes if the scrollable area gets too small (already tricky if the keypad is open e.g. on a phone). What kinds of things do you think you want to keep at the top most often? Is this like computed variable values? How many of them?

It's Mental Math Monday with the creator of Desmos, @eluberoff.bsky.social! With the digits 1, 1, 2, and 3, how many different 4-digit numbers can you create?

Also bonus question: What holiday was Desmos released on?

Desmos API Change Log

I'm at eli[at]desmos.com if we can help with the update. It's worth it, I hope - lots of improvements and no extra cost. More here: www.desmos.com/api/changelog

Quick follow up here - we updated the message to be less garish (standard console.warn now). Very sorry + grateful for bringing that to my attention. We also should only be showing this if 3 or more major releases (so 3+ years) out of date. please let me know if it's showing when it shouldn't!

Again though, frustration heard. We always try to keep in close contact with partners to make sure we don't get out of sync like this, and it sounds like we missed the mark here. I'm eli[at]desmos.com if I can help with this (or anything else, at any point).

(3) we only do this console if it's more than a year out of date (fwiw: our contracts always include a commitment to upgrade within a few months of each release. We don't enforce that, obviously, but it is a commitment for the above reasons)

(2) One reason for all of this is that we're constantly fixing small browser-compatibility things, improving accessibility, etc, and our team is way too small to support backports to arbitrarily old API versions. We commit to support the current and one prior, but further back than that is tough.

A few small details that might help: (1) updating should just be switching a v1.* to v1.11 somewhere. We work really hard at backwards compatibility so it should take no work past that, and there's no cost to upgrade to our latest version.

So sorry about the nuisance here, Chris! Which company are you with? I'm happy to help update however I can, and feedback received that a console warning feels unfriendly (we didn't want anything user facing).

Has this been a soul-searching moment for the fact-checking industry? Everything Harris says came, or is coming, true. And so much of it was labeled as "misleading" or "lacking context" at the time, on the grounds of "but he said he wouldn't!" (see, e.g. www.npr.org/2024/08/25/g... from @npr.org)

Every social theory undergirding Trumpism has been broken on the steel of Minnesotan resolve. The multiracial community in Minneapolis was supposed to shatter. It did not. It held until Bovino was forced out of the Twin Cities with his long coat between his legs.

The secret fear of the morally depraved is that virtue is actually common, and that they’re the ones who are alone. In Minnesota, all of the ideological cornerstones of MAGA have been proved false at once. Minnesotans, not the armed thugs of ICE and the Border Patrol, are brave. Minnesotans have shown that their community is socially cohesive—because of its diversity and not in spite of it. Minnesotans have found and loved one another in a world atomized by social media, where empty men have tried to fill their lonely soul with lies about their own inherent superiority. Minnesotans have preserved everything worthwhile about “Western civilization,” while armed brutes try to tear it down by force.

Last week in Minnesota, I watched ordinary people risk their lives to protect their neighbors. In the process, they not only won a significant—though not final—victory against authoritarianism, they proved virtually every MAGA social theory wrong. (gift link) www.theatlantic.com/ideas/2026/0...

I love this broken calc puzzles idea 😍. I think that turning off functions should be kind of straightforward, but turning off numbers and operations could be tricky... I imagine if "2" is broken you couldn't type "12" also, but what about if * is broken, should we break implicit multiplication too?

We've been talking about this one! Very hard to implement the general case in a way that'll work performantly with the rest of our system, but we're going to see what we can do.
