Find nine consecutive natural numbers and fill them into a square array, such that the sum of the three numbers in each row, column, and diagonal of the array is equal to 60.

(If you, like me, are a programmer who doesn't really consider yourself a "math person", fear not... a bit of thought + your programming skills will help you find a solution!)

I saw today that my CoCalc (https://cocalc.com/) license was about to renew. I've been meaning to move to a more #SelfHosting or #P2P paradigm, so this was good timing for me to cancel. I left this message when doing so:

"I want to support Sage, and I like using CoCalc, but I don't want to put money towards a service that supports Microsoft, Amazon, or OpenAI in any way. I didn't care so much about this before, and I even log in to CoCalc with a GitHub account, but I'm tired of having my work scraped for profit by people who donate to fascists who are destroying my nation. I would consider returning if all ties to these corporations were cut and cloud computing services came from responsible companies, perhaps in the EU."

I'm pretty sure I already have backups of everything I want from GitHub, so I can be done with them too. I should have quit when Microsoft first arrived. My plan is to switch to Radicle (https://radicle.xyz/) rather than another centralized service. I'll be sure to post about how that goes.

I admire anyone who puts this much diligence into a chat-up line.

"In Mathematics censorship and criticism cannot be allowed to everyone as in other sciences [...] ; the speeches of the rhetoricians and the defenses of the lawyers are worthless." – François Viète (1540-1603)

If America became fully fascist(which it likely will), how long will it last? Well, let's do a little chronology and math. Here are the number of years all the previous fascist nations of the last century lasted:

Italy: 21
Germany: 12
Spain: 36
Portugal: 41
Hungary: 0.5
Romania: 4
Slovakia: 6
Croatia: 4

If we use the mean formula (sum of numbers in set/number of units in set), we get an average of ≈15.6 years. So, expect around 16 years of American fascism.

I recently had a talk at CopenhagenJS to STOP using floating point numbers for math and money calculations. Today I became aware of PHP's `str_decrement` function which does "math" with strings.

It's like PHP heard me and went: HOLD MY BEER! https://www.php.net/manual/en/function.str-decrement.php
