Draw – Coordinates transformation of a table with multi-variable function values

In Mathematica, I have created a table for a function that depends on r and phi of the form

data = Table (f, {phi, 0, 2 x Pi, 0.5}, {r, 0, 20 x 10 -6, 0.5 x 10 -6})

Now I want to display this data in a 3D diagram, but to my knowledge, I would first have to transform the data into Cartesian coordinates, since Mathematica does not provide an easy way to draw functions that depend on multiple spherical coordinates (?).

I do not know which way is the best, because I'm new to Mathematica and do not really understand the syntax yet. I would be very happy about your help!

What is your honest opinion on the trump errors so far?

Ignore WT Door, who is an expert in Moscow trials because he lives there. He just tries to earn his trolling ruble from the GRU.

My honest opinion is that this was the source of many political achievements, but we knew that would happen. The Democrats have held a hearing on whether Trump has committed a criminal offense, and the Republicans have tried to hold their own hearing the Biden and the Whistleblower and literally anyone other than the one it is supposed to be about. If this is the best defense Trump has, it is not a very good one.

I still do not think the Senate will vote to remove Trump, but I do not think they would, even if they have video evidence that Trump is murdering a Hobo. The claims of the whistleblower were very well supported by each witness, even though it required several attempts by Sondland.

Ease of Use – Validity of inline help content over time as users switch from beginner to advanced

This is a question about an enterprise product.

Consider a selection menu –

Option 1

Help text (maximum 2 lines)


Option 2

Help text (maximum 2 lines)


Option 3

Help text (maximum 2 lines)


Remarks –

1) This help text has been added to the options as new users gave the feedback that the option label itself is not enough to indicate the intent of the option.

2) Advanced users state that they do not need to see the help text each time because they know the options well. That is very understandable.

Ask –

Our product has fairly distributed both ends of the user competence spectrum. Also note that users work overtime. A tooltip can not be used because we have found that it is being used less frequently and is causing additional friction for new users compared to immediate help. Given that standard principles of interaction design recommend designing for the intermediate user (Alan Cooper, Dan Normal) – is the tooltip the only way out? Or are there other thoughts?

Ask for advice. Thanks a lot!

System Agnostic – Save a character that does not fit into the group

I've been playing with my friends in a Warhammer campaign for about 7 months.

I have created a character that I thought would be interesting to me, as I intended to play him for a long time, and I wanted to give him some opportunities to develop his personality along that path. He was a thinker, not a great fighter, but he had a very high sense of self-worth and yet was completely unable to understand any form of sarcasm.
It turned out that I loved playing this character and the campaign went on and we had a really good time.

But recently we came into a situation where we had to infiltrate a place, and while one of my friends and I tried to find a way to go undetected, one of the others (playing a really reckless halfling) went to Leeroy Jenkins and decided to jump from one roof to another, followed directly by the other friend (a fearless knight). They discovered us, we were quickly surrounded by enemies and we were captured.

At the moment I got angry with her, and when I realized it, I decided to shut up. At the moment I really thought that they were ruining my fun and that this had to be tackled. But then I thought I might be the one who forces them to plan and organize things the way my character would.

The decision I made was to let my character go because he no longer had faith in his group. He did not fit his way of thinking, while the others got on well with each other. I was a bit sad to have to leave this character I liked to play, but I did not see any other solution and decided to create a character that fits in better with the team in terms of behavior.

Here's my question: Could I have "salvaged" my character before leaving the group? And if so, how?

Can I automatically run shortcuts for iOS Automation?

I had a problem where I sometimes forgot that the volume of my iPhone was quite high from a previous use. When I use my AirPods to make a call or listen to music, the volume is not automatically reduced to an appropriate level. Instead, loud, damaging noises are coming through my AirPods when the call starts or the music is playing, and I often have to remove them quickly.

I tried to fix this problem by using the new automation feature in shortcuts. I've created an automation that uses the Bluetooth trigger to run whenever my phone connects to my AirPods. In this case, the volume is set to 30%.

So far, so good.

However, when I use my AirPods, I only get a notification of shortcuts that I can use to execute the script (see below).

The little popup is actually a bit irritating – I want shortcuts to quietly regulate the volume without asking me to.

Enter image description here

Is it possible to have the automation function? automatically Execute a script when the trigger occurs?

Web Development – Architecture for replicating Dropbox Online File Viewer

I want to create an online website that has a similar feature to Dropbox. A teacher should be able to upload files so a student can view them without first downloading them. Dropbox supports viewing many files online, and it appears that only the parts displayed are provided to the client. My web application is a client-server architecture that consists of an Elm SPA that connects to a Go REST API. It only has to support the display of video, audio and PDF files. I assume that to display the file only the appropriate HTML5 component (for example) on the front-end page must be used (correct me, if I'm wrong), but in what format / on which Way, the files are deployed on the client side, so that:
1.) Is only the considered part delivered? (especially for pdfs – how do they serve only the page the user is viewing?)
2.) search is allowed? (Browse videos, etc.)

I read about:
1.) Partial content download
2.) HTTP 206 responses with range headers and
3.) Streaming protocols (RTMP, HLS etc.)

But I have no idea what to use in this case and if there is a better alternative. All instructions and resources for implementing this functionality are appreciated!

magento 2.1 – Custom column sorting of the UI component does not work

I'm creating 3 custom columns in the Sales Order Grid column:

  1. country
  2. Area
  3. city

Filters work, but when I try to sort the column, I see "Attention: An error has occurred".
