I have some data that looks like this:

I have this code which prints multiple tables

I have been blocked on this problem for several days. I have bootstrap 3.3.7 in the project root folder. I am rendering some buttons in the django template that should open modal windows when clicked. But the modal functionality is not working. I am following the examples shown on this page: https://www.quackit.com/bootstrap/bootstrap_3/tutorial/bootstrap_modal.cfm

Here is the template code:

I am making a simulation with C (for perfomance) that (currently) uses recursion and mallocs (generated in every step of the recursion). The problem is that I am not being able to free the mallocs anywhere in the code, without having the wrong final output. The code consist of two functions and the main function:

evolution(double initial_energy)

I am new to rust and I was reading up on using futures and async / await in rust, and built a simple tcp server using it. I then decided to write a quick benchmark, by sending requests to the server at a constant rate, but I am having some strange issues.

The below code should send a request every 0.001 seconds, and it does, except the program reports strange run times. This is the output:

I am trying to create a shopping cart in JavaScript. When I click on the button, the price of item should increase according to the number of times I have clicked on the button. I've tried the below code but it's not working. The problem is that after clicking few times the multiplication goes like this: suppose initial price =49
49 x 1
49 x 2
94 x 3
282 x 4 (it should be 49 x 4); I have modified the code,it works fine in console.log() but gives different result if I assign the variable newPrice to document.getElementById().innerHTML

I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)

I read this answer, which clarified a lot of things, but I'm still confused about how I should go about designing my primary key.

First off I want to clarify the idea of WCUs. I get that WCU is the write capacity of max 1kb per second. Does it mean that if writing a piece of data takes 0.25 seconds, I would need 4 of those to be billed 1 WCU? Or each time I write something it consumes 1 WCU, but I could also write X times within 1 second and still be billed 1 WCU?

Usage

I want to create a table that stores the form data for a set of gyms (95% will be waivers, the rest will be incidents reports). Most of the time, each forms will be accessed directly via its unique ID. I also want to query the forms by date, form, userId, etc..

We can assume an average of 50k forms per gym

Options

• First option is straight forward: having the formId be the partition key. What I don't like about this option is that scan operations will always filter out 90% of the data (i.e. the forms from other gyms), which isn't good for RCUs.

• Second option is that I would make the gymId the partition key, and add a sort key for the date, formId, userId. To implement this option I would need to know more about the implications of having 50k records on one partition key.

• Third option is to have one table per gyms and have the formId as partition key. This seems to be like the best option for now, but I don't really like the idea of having a a large number of tables doing the same thing in my account.

Is there another option? Which one of the three is better?

Edit: I'm assuming another option would be SimpleDB?

I have two functions one thats triggered on a mouseenter event and the other on mouseleave. Both of these functions are repeated three times.

On mouseenter the classlist "active" is addded 5x and the text content is changed. On mouseleave the classlist active is removed 5x and the text content is set to an empty string, and the original image is displayed again.

When the mouseenter event listener is triggered, Depending on which image is being hovered (3 images).
the text content property that gets added various between the three "Photosnap" "Dine" "Nike".
As-well as the background color that gets triggered various between "red" "blue" "pink".

Hover state shown as red left image and normal state shown as right image
-The image shown here is one of three. It is displayed with a red background and the text content of "photosnap".
-The other with a blue background and the text content of "Dine".
-The third and final with a pink background and the text content of "Nike".

I hope this paints a clear picture i am having a hard time making this a code snippet.

I am trying to refactor this javascript so its not so repetitive. I'm new to javascript and having a hard time getting this to work as something other than what i currently have. I'm not clear on how to make a function that i can call inside of other functions to cut down on the repeated code. Or possibly use the "this" keyword ?
