Happy π Day! And Albert Einstein was born #OTD 147 years ago!
https://en.wikipedia.org/wiki/Pi
Isaac Newton used infinite series to compute π to 15 digits, later writing "I am ashamed to tell you to how many figures I carried these computations".
https://en.wikipedia.org/wiki/Pi#cite_note-Newton-60
"I am enough of an artist to draw freely upon my imagination. Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world."

https://www.gutenberg.org/ebooks/author/1630@gutenberg_org sorry. Pi day in this country is not until 31st of April. April having only 30 days. So of course piday will not happen.

@gutenberg_org @capnthommo https://brilliantmaps.com/wp-content/uploads/2015/01/dateformat.png Only the US uses that format. The rest of the world doesn’t. Which was the point. See you on the 22nd of July!

https://www.gutenberg.org/ebooks/author/1630@gutenberg_org Hang on, are we talking about Taylor or McLauren series here? Just curious about what the state of the art was at the time.

@capnthommo @gutenberg_org I think we're still allowed to have maths-based fun even if the date thing doesn't make much sense to us :)

@muddle we need to access this book to get a proper answer https://books.google.com/books/about/Pi_Unleashed.html?hl=pt-PT&id=QwwcmweJCDQC

@drdusty Glad you managed it!

@muddle Should be Taylor series as mentioned here (as far as I remember): https://www.gutenberg.org/ebooks/76404

@gutenberg_org Thanks! I somehow thought that the Taylor series was somewhat later than Newton's work on calculus but I guess that they were contemporaries and Newton would have been aware of Taylor's work (as well as earlier formulae for pi).
This could become a bit of a rabbit hole, but I'm reminded of Fabrice Bellard's more recent calculations (probably since surpassed?) and wondering what new techniques he used...

@gnarf @gutenberg_org I know. I was just having a little fun of my own playing agent provocateur

Romagna mia fatti capanna / 2
@anarchia
Gli affitti esaaaaaaaaaagerati dell’ Azienda ASL. di Davide Fabbri (*) Una inchiesta sullo spreco di danaro pubblico dell‘Azienda USL della Romagna. Sono letteralmente vergognosi – quasi inverosimili – i canoni annui di locazione che l’Azienda USL della Romagna ha corrisposto...Vedi l'articolo

I received a phone call from a rival company asking for a character reference for one of my staff. The employee in question is the worst in my team. Incompetent, always late, and not the nicest of people. So of course I gave the most glowing reference I've ever given.

@heals I have a 500 character limit when writing any kind of post including supplies. People who are not on stock mastodon often have a much higher character limit, and some of those people do not have the ability to say anything important in under 1000 words

È vero: su Android la maggior parte delle persone usa Chrome non perché sia migliore, ma perché è preinstallato. Stesso discorso per il motore di ricerca impostato di default.
Solo l’idea di cambiare browser è già fuori dalla comfort zone per molti.Personalmente uso Fennec F-Droid https://f-droid.org/it/packages/org.mozilla.fennec_fdroid/

Quick update since I rebased this branch for (eventual) 3.4 development. I cleaned up the channel code a bit so it now properly separates out the Key channel from the Cyan/Magenta/Yellow channels.
