Been following the #MkDocs drama for some time. So sad to see a project with so much potential struggle so much. Hope a new maintainer is found soon https://github.com/mkdocs/mkdocs/discu

I am stepping down from MkDocs · mkdocs mkdocs · Discussion #3621
3 years ago I was given push access to MkDocs among a few other people, without a single word regarding how anything should be done. Even the ability to make a release hinged on a leftover API toke...

I’m becoming more and more resolute on getting a tatoo for my 50th birthday (in June).

As this would be my first one, I thought I’d just pose an open question: is there anything I should think through regarding size, placement or other aspects. Happy to get advice from people more experienced. I expect there are many rookie mistakes to avoid.

The tatoo will be Africa-related and likely involve a map of Africa. So, yeah, I have not decided on the artwork yet.

Increasing-decreasing patterns in the iteration of an arithmetic function
Let $Ω$ be a set of positive integers and let $f:Ω\rightarrow Ω$ be an arithmetic function. Let $V = (v_i)_{i=1}^n$ be a finite sequence of positive integers. An integer $m \in Ω$ has \textit{increasing-decreasing pattern} $V$ with respect to $f$ if, for all odd integers $i \in \{1,\ldots, n\}$, \[ f^{v_1+ \cdots + v_{i-1}}(m) < f^{v_1+ \cdots + v_{i-1}+1}(m) < \cdots < f^{v_1+ \cdots + v_{i-1}+v_{i}}(m) \] and, for all even integers $i \in \{2,\ldots, n\}$, \[ f^{v_1+ \cdots + v_{i-1}}(m) …

Update: After 8 hours of concentrated work broken only by 20 minute lunch break and 2 half hour meetings, I have managed to cut down a 2500 email inbox to just under a thousand...

Stability theorems for positively graded domains
Given a Noetherian graded domain $R = \bigoplus_{i\ge 0} R_i$ of dimension $d\geq 2$ with $\dim(R_0) \geq 1$, we prove that any unimodular row of length $d+1$ in $R$ can be completed to the first row of an invertible matrix $α$ such that $α$ is homotopic to the identity matrix. Utilizing this result we establish that if $I \subset R$ is an ideal satisfying $μ(I/I^2) = \text{ht}(I) = d$, then any set of generators of $I/I^2$ lifts to a set of generators of $I$, where $μ(-)$ denotes the minim…

I have a feeling that Simply Piano is the learning experience that DuoLingo wishes it was. I know they have different financial models but not being punished for mistakes makes a *huge* difference (to me, probably to others too).

My only good shot from totality (after I remembered to take the filter off the lens! 🤦‍♂️🤣). Totality was amazing and so I was drinking it all in. Temps dropped a good 10 degrees F, mosquitoes came out, the birds stopped singing, everyone’s solar lights came on, and it was incredibly dark. Really amazing!
And then it was over and everything started returning to normal!
