It's Leonhard Euler's birthday today! He was born in Basel on April 15, 1707.
Euler was a relentlessly energetic mathematician, physicist, astronomer, geographer, logician and engineer who founded the subjects of graph theory and topology and made pioneering discoveries in analysis, number theory, mechanics, fluid dynamics, optics, astronomy and even music theory. When he lost sight in his right eye, he remarked
"Now I will have fewer distractions."
and even when he became almost blind in his other eye he averaged one paper a week.
I love how he seized the day and explored all the possibilities available to him. Harnessing the tools of calculus, he came up with dozens of amazing formulas, like the one below.
But how do you find a formula like this???
It's not magic: it uses a method called "Euler's continued fraction formula" which can produce *many* similar formulas. This method is not easy to guess, but you can check it using high-school algebra, especially if you don't worry about convergence - which Euler didn't, not much anyway. Then, to apply this method, you need to know some calculus.
Let's see how it works!

@Pwnallthethings great stuff and great to see you back on Mastodon. do stay.
@timkmak sorry, I didn't realize that. ok then, some Canadians:
John Rieti, Jennifer Pagliaro, Ben Spurr, Michael de Adder (he is on Mastodon but has stopped posting here), André Picard, Matt Elliott, Ed Tubb, Aaron Rose, Blake Murphy,
Also,in my earlier list I should have mentioned Jon Passantino and Olivia Solon.
Sarah Sanders blames 'design error' for form asking job applicants to name something nice about her https://www.rawstory.com/sarah-sanders-job-application-form/
@mattblaze @delfuego thank you for the clarification. It does seem to me that espionage is unlikely to be in play here. But we'll see.
@delfuego @mattblaze thanks, that's what I always thought. Was therefore very surprised by Matt's post.
Some interesting tidbits from the warrant affidavit for accused leaker Teixeira:
https://www.documentcloud.org/documents/23777278-teixiera-affidavit (HT @kevincollier )
- He was arrested yesterday, but the warrant was issued this morning, which suggests he was arrested as an emergency measure. Things moved quickly in the last two days.
- At least one of the Discord users ("User 1") is cooperating. I wonder if it's the kid in the WaPo piece or someone else.
- Some "consciousness of guilt" in the access logs thrown in in ¶ 27.
“running a Nazi bar is not […] standing up for free speech. It’s building your own brand as the Nazi bar and abdicating your own free speech rights of association […].”
[…]
"your reputation when you refuse to moderate is not “the grand enabler of free speech.” Because it’s the internet itself that is the grand enabler of free speech. When you’re a private centralized company and you don’t deal with hateful content on your site, you’re the Nazi bar.”
From @mmasnick:
@nirnaeth there are also notification APIs. those don't require any extra tools for the user like Feedly. somehow none of the blogs I follow use them. only sites I do not care about try to offer me notifications.
@timkmak totally forgot Michael Weiss. he should be right up there near the top of the list.

thank you that was very helpful
