samsung – Messages for web not updating with new texts and statuses

I am trying to use Android Messages for web. I am able to connect to the phone using the QR code, but after the initial connection, I do not get new messages automatically or any notification – I have to reload the page to see them.

When I send the message, the “Sending…” status remains and is not updated to “Distributed” either.

I have tried in Firefox and Chromium. I am using Ubuntu. The computer and phone are on the same network, and I tried with the computer using a cable or WiFi. The phone is a Samsung Galaxy S9 and the app is allowed to run in background (no battery optimisation).

I have had the problem for quite some time now, I couldn’t say if it used to work in the past.

Relations between many category theory structures – introductory texts

There are many kinds of category theory structures. What are some good texts and good ways to remember the relations between them? For example, can there be a web of embedding relations between these category theory structures? (where can I find those webs to read.) Like which ones contain the other ones as more general cases. (Intersections and unions between different category theory structures.)

  • unitary braided fusion category = unitary premodular category

  • unitary fusion category

  • unitary symmetric fusion category

  • unitary modular category

  • monoidal category = tensor category

  • spherical fusion category

  • modular tensor category

Here are some facts I know of

1.

$$
text{unitary braided fusion category = unitary premodular category} supset
left{
begin{array}{l}
text{(1) unitary symmetric fusion category}\
text{(2) unitary modular category}
end{array}
right.
$$

  1. The center construction of spherical fusion category defines a modular tensor category.

Please feel free to make comments and give a list of advices.

evaluation – Mathematica 12.1 is treating all my cells as raw texts by default

I was once using Mathematica 11 it all works fine – when I create new Notebook (.nb) input like 1+1 and press shift+enter, it shows output(1):= 2 directly

But now for 12.1 when I create new notebook and do the same thing, it is treating my input 1+1 as plain text by default, when i press shift+enter there is just a linebreak.. no evaluation at all.

I find when I go to the menu -> cell -> cell properties and tick Evaluatable then the input can work well as Mathematica 11. BUT when i input Plot(x,{x,1,2}), it gives output -Graphics-!! Without showing what the graphic is! I then have to manually convert the output cell to StandardForm to show the graph! I have to do such things everytime, why is 12.1 getting me so much ados ..and how can i remove such tedious things making it funcation just like what mathematica 11 does?

Pardon me I’m a complete nooooooob and really searched goooogle tons of times not getting the answer….

unity – Change Text – Inside A button, inside a Canvas, inside a GameObject: Access all the texts inside of hierchy?

//....
Gameobject tile;
int count = 1;
float posX = 0;
float posY = 0;
....//

GameObject blueTile = (GameObject)Instantiate(Resources.Load("block_blue"));
tile = (GameObject)Instantiate(blueTile, transform);

for loop {
   ...
   ...
   tile.GetComponent().GetComponentInChildren().text = count.ToString();
   tile.transform.position = new Vector2((float)posX, (float)posY);
   count++;
}

As you can see by the image.
My line of thinking goes like this; I used to create Flash/AS3 Applications and Games. I have used a number of API’s and they usually have a lot in common. Unix, however, is very different and I may have not grasped the key concepts.

I want to access my PreFab, named in Assets/Resources (the root path)

“block_blue”

All I wan to do is set up a row and columns of a box with a number inside of it.

Before you go and ask, why the complicated mix of Objects? Well, Adobe had MovieClip and use of layers and also use of a timeline. Unix doesn’t seem to have this in setting up a Scene (the Stage in Flash).

So, I set up a block that looks like this (right of main image 66):
It’s a Canvas, to hold a Button, the button has a text. To move the Canvas, I put the Canvas inside a GameObject. This, to me, is like a MovieClip in Flash API.

**GameObject > ButtonLight, Button > TextBlack, Text**

I need to access TextBlack and also Text. Pretty easy right? I’ve been at this for 4 days, many many hours.

EDIT: It seems that it is working, somewhat.

Looking at the reference photo and the Hierarchy reference, it looks like the blackText behind the blueText is changing as expected. But I cannot access the top BlueText. The Blue Text is also a child of type Text, but it’s a second (layer?) copy of the text inside of the Button. So, it’s getting the first Child Text, but how to access the second Text?

python – Is there a way to visualize texts using a map?

I have a corpus about a particular topic and will analyse the themes on that corpus. Once the themes are identified, I have to associate those themes on a specific location on a map of a particular city where they frequently occured. For example, a theme of “unstable” occurred in XYZ town, I want the word “unstable” on top of location of XYZ town on the map so that when I hover my mouse over XYZ town, the word ‘unstable’ appears. Is this possible to accomplish in Python? If so, which libraries can be helpful?

formulas – How do I find the max value in a column only if it contains certain texts in google sheets?

you can cast a regex function with a capturing group over your entire column using an array and return the max item from the array.

=MAX(ARRAYFORMULA(INT(IFERROR(REGEXEXTRACT(C2:C9,"NB(d+)"),0))))

667

enter image description here

Regex Explanation.

NB matches the characters NB literally (case sensitive)

1st Capturing Group (d+)

d+ matches a digit (equal to (0-9))

+ Quantifier — Matches between one and unlimited times, as many times as possible, giving back as needed (greedy)
