Math teacher behind ProvocaTeach – a spicy little blog about making education better. I believe in play, openness, flexibility, care, & sufferance. Read my work at https://provocateach.art

The fact that Apple is disabling progressive web apps on iOS is an attack on competition and freedom in the app development space. I hope the EU hands their ass to them.

I thought I'd heard every reason math teachers are evil and math education is broken, but I guess I was wrong.

According to one Reddit math major, we are harming students by teaching that y = x^2 is a function.

It's not a function, he says, because it's not written with an f(x). 🤦‍♂️

Twitter is now my X 💔

Republicans are proposing an 80% cut to Title I.

Title I gives federal money to schools based on the number of low-income students. The program has been around since 1965.

This is wrong, especially coming from a party that claims to be sticking up for parental rights. What about low-income parents? Do their kids not deserve a high-quality education?

Call your representatives and tell them to oppose this bill.

Look, buddy, if all you want to talk about is tech and cryptocurrency, you're probably happy right now.

I, personally, would like there to be some lawyers, teachers, professors, politicians, writers, economists, world travellers, chefs, comedians, parents, athletes, accountants, chemists, physicists, salespeople, marketers, truckers, and boomers on here.

I feel like we're missing a lot of folks....

Anyone else worried that Meta is going to take over everything?

Most people want an easy-to-use site where they can expect reasonable content moderation by default (perhaps with an opt-out). And Nostr, for all its truly important innovations in privacy and decentralization and freedom of speech, is *not* easy to use and does *not* give people reasonable content moderation by default.

I know nostr:npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6 had a plan for allowing relays to set their own content moderation standards. However, as currently implemented, this gives users very little agency. Most comparison sites don't give you an easy way to see relay content policies; I've seen little evidence that content is *ever* moderated; and most clients encourage users to connect to 8-9 relays anyway, so your feed is still likely to get flooded with unmoderated sludge.

For example, suppose relay 1 is cool with criticism of religion, but relay 2 isn't. Where am I supposed to see that, as a user? There are no community guidelines available to read.

Nostr is already a little more hardcore thanks to the public and private keys. Now, I think public-key cryptography is the future of authentication whether we like it or not. So I'm cool with Nostr taking a stand on it. However, we have to keep track of how many barriers normies face signing up.

We need to get the normies on board if we want to beat Threads.

Code-based #cryptography: the perfect summer reading material.

Using the Fiat-Shamir protocol, this can be turned into a post-quantum digital signature algorithm, suitable for blockchain and other applications.

Happy Mother's Day to the Constitution! 🎆

Thank goodness for all the new Nostr users. I was worried this thing would be all Bitcoin all the time for eternity 😭

It's kinda like Bitcoin, but it's not on the actual Bitcoin blockchain.

The public key and a "digital signature" are sent over the wire with every note, like, repost, etc. (collectively called "events") you make on Nostr. The events are stored on the relay servers.

(OK, if that's enough for you, you can stop reading here. To learn more about the signature, read on.)

The signature is made with your private key and the message. Anyone who has the public key and signature can, through some math calculations, verify that they match. That's how the network knows it's you.

If I wanted to impersonate you, I would need to craft a digital signature that matches your public key. This is *nearly impossible to do* without the private key; I would need to basically try random signatures over and over again for years.

For more info, there's a great Computerphile video.

Kind of. You can get something called NIP-05 verification.

https://nostr.how/en/guides/get-verified

You may notice I have noahg@provocateach.art under my profile. I verified that I am affiliated with the domain provocateach.art by putting a special file on that website. That file says, "Hey, this public key refers to noahg." Since no one else (ideally) has access to that website, they know it's me.

If you don't want to set up your own website, nostrplebs and Iris and some others offer NIP-05 verification for free. So you'd get something like yuta@iris.to

Your public key / private key pair is what distinguishes your profile.

There is a display name that can be whatever you want.

Some clients (such as Iris) also allow you to register a separate username.

Imagine if we started calling this thing Cosa Nostr

This is a highly impactful decision, and I have mixed feelings about it.

In a just world, we wouldn’t need affirmative action. It was always a stopgap measure intended to correct for huge racial inequalities earlier in the pipeline – in academic opportunity, wealth, and housing.

To me, affirmative action always sent the message that we were OK with these inequalities. After all, adding a few points during the admissions process is much easier than making sure every student is equally prepared to succeed in college.

Now, affirmative action is gone – but structural inequalities in the K-12 system remain. Hopefully, we can refocus our efforts from the symptom to the cause.

Every student deserves equal access to a free, effective, and powerful education that prepares them for college or whatever else they wish to accomplish. That goal is far more important than any admissions policy.

(P.S. There is also a campus diversity argument to consider. However, California’s ban on affirmative action seems not to have impacted the racial makeup of its public colleges much, even after 27 years.)
