I am trying to add a ruby tag for every word in a paragraph. The html doc looks somthing like this

I am very new to DC/D3 libraries. I am trying to incorporate DC with ReactJS by having a separate pure JS file that is a reusable D3 component. I am following this example here. Here is the dummy data I am using: json snippet.

This is my App.js:

I was solving a problem to determine whether a graph contains a cycle. I solved it using the coloring method (in the visited array I will mark, 0 if it has never visited, 1 if it is visited, and 2 if the tour of vertex is done) for this I wrote the code:

I am in college learning SQL vis Postgresql. This is my first post here so if I'm not posting correctly, let me know. I have a question that has me stumped.

A bank setup with multiple users having multiple accounts at multiple branches in multiple cities. The question wants to find any users that have at least 1 account at every branch in a specific city.

There are 3 branches in Brooklyn. I need to find all user ID's that have at least one account in each branch.

If they do not have at least 1 account in each branch, it should not return anything for that user.

I don't know how to return multiple rows with different results from the same column and REQUIRE the specific branch names be present or return nothing at all. (userID = a on one row, b on another row, c on anther row or do not return userID at all.) I do not want the entire answer, I just need to know what function I can use to do this and maybe some general guidance on what to do.

I can provide the table information if needed.

Thank you.

I have run some Python code in Windows 10 and gotten the Traceback error below. Does it mean the string that is supposed to be an int occurs in line 347 of /DeOldify/deoldify/filters.py or line 1943 of /lib/site-packages/PIL/Image.py?

For context, below the traceback error, I've also included the steps that lead to this error (I attempted to colorize a black and white film clip based on the DeOldify Colab https://colab.research.google.com/github/jantic/DeOldify/blob/master/VideoColorizerColab.ipynb but only succeeded at colorizing the first frame as a .jpeg) and the full terminal output.

EDIT: Thanks to @Daweo's response, I discovered the problem was with the arguments I entered into the terminal as indicated by "", line 1. The correct command should have been:
video_path = colorizer.colorize_from_file_name(file_name='my_video.mp4', render_factor=render_factor)
Also, the code for colorizing a photograph is from https://colab.research.google.com/github/jantic/DeOldify/blob/master/ImageColorizerColab.ipynb

I'm currently going through the paper Extensibility for the Masses. Practical Extensibility with Object Algebras by Bruno C. d. S. Oliveira and William R. Cook (available many places on the internet - for example here: https://www.cs.utexas.edu/~wcook/Drafts/2012/ecoop2012.pdf).

On page 10, they write:

Adding new data variants is easy. The first step is to create new classes Bool and Iff in the usual object-oriented style (like Lit and Add):

I have hand-written an ELF32 object file that I would like to link via. gcc but I get an undefined reference when I try to use my function/label. I have it defined in a test C file as extern yet this does not change anything.

This object file contains the following assembly:

I'm creating this website for a company for my student co-op and I had this header made for my website and when I made it, it worked completely fine. Now when I check on my phone I press the services button for my dropdown menu and it doesn't come down, but when I try on the google chrome dev responsive tool, I can click the drop down menu but I also cant unclick the menu. I understand that I have a lot of code written in my CSS file, I do have stuff labeled though like header/home page.

My Issue:

When I click on my responsive navbar when it's resized to a smaller ratio. I click the bar and my nav menu pulls up but when I click on my services drop down menu It doesn't come down, Although it works on google chrome responsive dev tools. But when I click the services button and it works the dropdown wont go away when I click it again, how can I fix this? Majority of my navbar is labeled "Header" in my css file. I decided to put my whole file in as maybe something is over writing it but I have no clue it is?

I am trying to import from a file with a name passed from console. This works for the first import from JSON, but when I try to import a js file, I can't use the function:
