macos – Apple Music Library Does Not Sync Correctly Between Two Macs

I use a Mac mini as a server and an iMac to work on. I maintain my music collection on the iMac, but I regularly copy the chances over to the Mac mini using an AppleScript with a rsync command.

This used to work fine for the time I was using iTunes. Now, under Catalina, changes to the library are not noticed by the Apple Music App on the Mac mini.

I know the Music Library file is updated correctly, and also the individual albums and songs get copied to the Mac mini just like they should. For example, Roon is running on the Mac mini too, and it notices the changes. But the Apple Music App just shows the status of the collection of the time where I first copied the whole collection to the Mac mini.

Are there some cache files somewhere I have to take care for? So far, the AppleScript syncs the folders /Users/User/Music/iTunes and /Users/User/Music/Music (only from iMac to Mac mini).

formatting – HowTo “correctly” avoid clipping in GraphicsRow[{Labeled[Graphics[]]}]? Both images and labels

$Version

(* "12.1.1 for Mac OS X x86 (64-bit) (June 19, 2020)" *)

gr = GraphicsRow({Labeled(Graphics({Circle()}), 
    "A(ThinSpace)=(ThinSpace)B(ThinSpace)-(ThinSpace)!(*FractionBox(
(C), (2)))"), 
   Labeled(Graphics({Circle()}), 
    "A(ThinSpace)=(ThinSpace)B(ThinSpace)-(ThinSpace)!(*FractionBox(
(C), (2)))")})

enter image description here

The clipping does not occur. Compare your values for these options

AbsoluteOptions(gr, {ImageMargins, ImagePadding, PlotRange, PlotRangeClipping,
   PlotRangePadding})

(* {ImageMargins -> 0., ImagePadding -> All, 
 PlotRange -> {{0., 1152.}, {-606.9, 0.}}, PlotRangeClipping -> False, 
 PlotRangePadding -> {6., 5.}} *)

Perhaps one or more defaults have been changed.

EDIT: Using an older version I observe the problem

$Version

(* "12.0.0 for Mac OS X x86 (64-bit) (April 7, 2019)" *)

GraphicsRow(
 Labeled(Graphics({Circle()}), #) & /@ {
   "A(ThinSpace)=(ThinSpace)B(ThinSpace)-(ThinSpace)!(*FractionBox((C),
 (2)))",
   "A(ThinSpace)=(ThinSpace)B(ThinSpace)-(ThinSpace)!(*FractionBox((C),
 (2)))"})

enter image description here

The easiest solution is to use Row instead of GraphicsRow

Row(Labeled(Graphics({Circle()}, ImageSize -> Small), #) & /@ {
   "A(ThinSpace)=(ThinSpace)B(ThinSpace)-(ThinSpace)!(*FractionBox((C),
 (2)))",
   "A(ThinSpace)=(ThinSpace)B(ThinSpace)-(ThinSpace)!(*FractionBox((C),
 (2)))"})

schema.org – Am I formatting this FAQ Microdata Markup Correctly?

Am I formatting this FAQ Microdata markup correctly?

I added FAQ Microdata markup to pages similar to this:
https://www.catseyepest.com/pest-library/bees-hornets-wasps/wood-wasps-horntails

The code seems to be displaying as:

<div itemprop="mainEntity" itemscope="" itemtype="https://schema.org/Question"> 
<h3 itemprop="name">What is the difference between horntail wasps and bees?</h3> 
<div itemprop="acceptedAnswer" itemscope="" itemtype="https://schema.org/Answer"> <div itemprop="text"> <p>Horntails wasps, although cousins of the wasp, are not truly wasps. They do not sting or bite. They are rather large, about an inch long, and the female horntails have a long horn-like tail that is used for depositing eggs into a tree. H3: Are horntail wasps aggressive? Horntail wasps are completely harmless. These insects are not true wasps and can’t sting or bite.</p> 
</div>
</div>
</div>

The website appears to be changing the original code to itemscope="" when that is not how it is displayed in the Google example.

This markup seems to work well until I updated it because I noticed that I added:

<div itemscope itemtype="https://schema.org/FAQPage">

Then removed it and now the impressions and clicks from FAQ markup have dropped off.

Do I need to keep the above line in? Does it matter that the page isn’t specifically a FAQ page only?

When I test this in Structured Data Testing Tool, it comes back with no errors as Question.

But the Rich Results Test says the page is not eligible for rich results.

Could anyone let me know the proper way to use microdata here?

xml sitemap – Can’t view my page map correctly?

I have installed the geolocation module to view the location maps that I have on my website
enter image description here

Also I checked the Google map API , and added google maps API key , after create the location content type and make sure that Manage form display to show me the geolocation google map api – geocoding and map
enter image description here

then I added the content that I want but I got this error (this page can’t load google map correctly)
enter image description here
is there something wrong with the steps that I followed?

spellcasting – Am I correctly understanding the number of spells a wizard can prepare?

Looking at the Dungeon Worlds’s Wizard playbook Prepare Spells move, it seems quite clear how it works at the first reading:

When you spend uninterrupted time (an hour or so) in quiet contemplation of your spellbook, you:

  • Lose any spells you already prepared
  • Prepare new spells chosen from your spellbook whose total levels don’t exceed your own level +1
  • Prepare your cantrips which never count against your limit

So, assuming that wizard reaches 9th level (not very realistic in DW, but just for sake of argument), and decides to take one of the 9th lvl spells, he will have two spells prepared – his 9th level and some other 1st level. If he had chosen proper moves while advancing, he could possibly prepare 9th level and 3 1st level spells, but that’s it.

Do I understand it correctly, that regarding spells, wizard can chose from very limited amount of spells prepared at once, unless he reaches high level and decides to stick with only with low-level spells?

calculus and analysis – How to find the limit correctly

I want to use MMA to find the limit of $lim _{n rightarrow infty}left(frac{sin frac{pi}{n}}{n+1}+frac{sin frac{2 pi}{n}}{n+frac{1}{2}}+cdots+frac{sin pi}{n+frac{1}{n}}right)$.

Limit(Sum(Sin((i*Pi)/n)/(n + 1/i), {i, 1, n}), n -> Infinity)

However, the above code does not get the correct result (the answer is $frac{2}{pi}$).

What can I do to get the right results?

calculus and analysis – How can I calculate the sum of this series correctly?

I already know that this numbers series $sum_{n=1}^{infty} frac{1}{3^{n}+(-2)^{n}} frac{(-3)^{n}}{n}$ is convergent.

SumConvergence(((-3)^n/(3^n + (-2)^n) 1/n), n)(*True*)

But the following code can not find its limit value, I want to know how I can correctly find the limit value of this series?

Limit(Sum((1/(3^n + (-2)^n))*((-3)^n/n), {n, 1, m}), m -> Infinity)
Needs("NumericalCalculus`")
NLimit(Sum((1/(3^n + (-2)^n))*((-3)^n/n), {n, 1, m}), m -> Infinity)
