standalone | PHP code for standalone command line version of UUP dump | Development Tools library

I looked for solutions here: Multiply columns in a data frame by a vector and here: What is the right way to multiply data frame by vector?, but it doesn't really work.

What I want to do is a more or less clean tidyverse way where I multiply columns by a vector and then add these as new columns to the existing data frame. Taking teh data example from the first link:

All of a sudden I am getting an error - 'Current topology does not support sessions' on MongoDB Compass. I have never seen this before on MongoDB Compass!!!

Below are the details on version/server

I want to implement some kind of notification system in my application but I have trouble with the calculation of the actual position of my notification. All notifications should appear in a separate stage and each notification should be aligned among themselves and each notification is a simple VBox with two labels (title and message).

I created a little standalone application with the issue I have.

As soon as you press the button on the main stage, a VBox will be created and added to a second notification stage. As soon as a seconds notification needs to be added, this second notification should be below the first notification and so on. Therefore I need to find the height of the first notification in order to position the second notification underneath.

I know I could use a VBox instead, but in my application the notification should make a smooth animation and push the other notifications further down. I removed the whole animation and removing part of notifications so the example stays as small as possible.

The problem is that all notification boxes have the same height - but they don't (if you modify the text and make it longer / smaller).

When I try to run command ng lint --fix cli throws this error:

I frequently receive PDFs that contain (when converted with pdftotext) whitespaces between the letters of some arbitrary words:

This i s a n example t e x t that c o n t a i n s strange spaces.

For further automated processing (looking for specific words) I would like to remove all whitespace between "standalone" letters (single-letter words), so the result would look like this:

This isan example text that contains strange spaces.

I tried to achieve this with a simple perl regex:

s/ (\w) (\w) / $1$2 /g

Which of course does not work, as after the first and second standalone letters have been moved together, the second one no longer is a standalone, so the space to the third will not match:

This is a n example te x t that co n ta i ns strange spaces.

So I tried lockahead assertions, but failed to achieve anything (also because I did not find any example that uses them in a substitution).

As usual with PRE, my feeling is, that there must be a very simple and elegant solution for this...

I have two files main.raku and TestMod.rakumod in a directory C:\Users\suman.

TestMod.rakumod

how can I move the current label closer to the current arrow. I.e. I want to move the i_1 closer to the arrow.

How can I make a standalone Windows executable(.exe) for my JavaFX project(I wrote in IntelliJ IDEA), without an installer for my program? I want the user to download the .exe file and run it out of the box, without an installer, even if they don't have a JRE on their computer. Is this even possible? So far I've read a little about the following options:

• launch4j - It seems to copy the required JRE files alongside the .exe
• install4j - It makes an installer, which, once runned, creates the .exe file.

So, if I have understood correctly, neither of these two will help me. I found this and this posts, but they don't cover my specific case. Excuse me, if I'm asking a stupid question, this is my first ever Java GUI.
