This War Will Destabilize The Entire Mideast Region And Set Off A Global Shockwave Of Anti-Americanism vs. No It Won’t George W. Bush may think that a war against Iraq is the solution to our problems, but the reality is, it will only serve to create far more.

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?

same, but hopefully not for too much longer! also, that hack is awesome...

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 We also should only be showing this if 3 or more major releases (so 3+ years) out of date.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(3) we only do this console if it's more than a year out of date (fwiw: our contracts always include a commitment to upgrade within a few months of each release.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).

Help MN and maybe win these mittens! I’ll draw a name 2/1, so get me your name by 7pm central tomorrow.

Every $5 you give to mutual aid and every phone call to your reps is an entry. Email a pic of your receipt/call to mplsAngryMittens@proton.me

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 cohesiveβ€”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 β€œWestern 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 significantβ€”though not finalβ€”victory against authoritarianism, they proved virtually every MAGA social theory wrong.

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.

Love this idea! It's a tricky one to do in general because to render arbitrary opacities can be a performance nightmare (the leading technique, depth peeling, can be incredibly computationally intensive with many layers of low opacity surfaces). But we're working on it :)

There was so much confusion of people thinking that Desmos was all part of Amplify, sending us support requests about parts that we don't have any control over etc, and it was actually making things kind of hard for Desmos Studio (and I imagine for Amplify as well on the other side)

04.12.2025 01:07 πŸ‘ 5 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I wasn't involved in that decision, but one benefit is that it's now so much clearer which parts are Desmos (e.g. the calculators and everything else at desmos.com) and which parts are Amplify (e.g. activity builder etc, now at classroom.amplify.com)

not sure why it's suggesting those... the syntax for domain restrictions in Desmos is { condition }, e.g.: www.desmos.com/calculator/j...
