## Help locating Javascript for Mouse Drag

I recently started working for a company that had been getting all of its software provided by overseas developers.

I was hired on because of my years of experience in software, but all of those years were in Windows Forms using C#. This project is still in Visual Studio, but largely it is controlled by HTML, CSS, and Javascript – which I am not good at.

My assignment right now: When User drags on a row on a table, a pointer appears on the left of the grid control, follows the row to indicate where the row is able to be dropped, and the row is moved to that location when the User releases the mouse.

Right now, the mouse is not moving 1 to 1 with the arrow. The more rows in the grid, the greater the discrepancy between the mouse and the pointer.

In the image above, the mouse is on “jp2code 035” while the pointer is up at “Task 13”.

I went into the Chrome console’s Source tab, went to the Event Listener Breakpoints, and put one on “Mouse > click”, but it didn’t break any execution.

I am not here to get you to solve the issue for me, but I don’t know how to find the code associated with this.

The file that is being called is called TaskListViewer, but it has no controls in the designer and very little code behind. Everything is loaded by the master page and source scripts.

Can anyone offer suggestions on how I could go about locating where the issue is in Javascript? For a Windows Forms application, I would simply look at event handlers for the control.

## Locating Eigenvalues with Arnoldi’s Method

Currently reading through Numerical Linear Algebra by Trefethen – Bau, Lectures 33 and 34 on the Arnoldi Iteration.

I’m having trouble understanding how and why exactly does the Arnoldi Iteration find eigenvalues. The book shows that the the characteristic polynomial of $$H_{n} = Q_{n}^{*}AQ_{n}$$ is the unique polinomial of degree $$n$$ such that $$||p^{n}(A)b|| = text{minimum}$$
The book then establishes a connection between this minimization problem and finding the eigenvalues of $$A$$, which I fail to follow.

Could someone please provide some insight/proof on why the eigenvalues of $$H_{n}$$ produce estimates for some eigenvalues of $$A$$ and why do these converge to the eigenvalues of $$A$$?

## unity – Best Practices for Locating Clicks

I am building a 2D board game in Unity with a static camera pointed down at the game board. During the active phase of each player’s turn, I want to detect where they click on the board. Fortunately, the board is laid out in an easy rectangular grid. (Essentially a trio of 5×5 grids).

Which of the following would be best practice to implement this?

1. Create invisible colliders for every square on the board and create a translation function that translates those back to board positions (5,3) with Raytracing?

2. Get the translated coordinates of the click and use a function to figure out which square (if any) the click is in using the mouseclick event handler (by calculating which square the grid coordinates fall in)?

3. Make each square a button with its grid identity encoded and use that in its “OnPressed” function?

Experience level: I’m just learning unity, but have written a lot of C# (and tons of other code).

## python – Foobar Challenge- Bunny Prisoner Locating

Keeping track of Commander Lambda’s many bunny prisoners is starting to get tricky. You’ve been tasked with writing a program to match bunny prisoner IDs to cell locations.

The LAMBCHOP doomsday device takes up much of the interior of Commander Lambda’s space station, and as a result the prison blocks have an unusual layout. They are stacked in a triangular shape, and the bunny prisoners are given numerical IDs starting from the corner, as follows:

| 7

| 4 8

| 2 5 9

| 1 3 6 10

Each cell can be represented as points (x, y), with x being the distance from the vertical wall, and y being the height from the ground.

For example, the bunny prisoner at (1, 1) has ID 1, the bunny prisoner at (3, 2) has ID 9, and the bunny prisoner at (2,3) has ID 8. This pattern of numbering continues indefinitely (Commander Lambda has been taking a LOT of prisoners).

Write a function solution(x, y) which returns the prisoner ID of the bunny at location (x, y). Each value of x and y will be at least 1 and no greater than 100,000. Since the prisoner ID can be very large, return your solution as a string representation of the number.

The following is the code that I wrote that.

``````
def solution(x,y):
n=x+y-1
s=(n*(n+1))//2
res=s-y+1
return str(res)

``````

The question looked pretty straight forward but not even one test case passed when I tried this code.
The code seems to work just fine on other ide’s.
Is my solution correct or did I understand the question completely differently?

## Locating faults using model verification

In many articles like the empirical evaluation of the technique of automatic localization of tarantula defects, there is a good explanation on how the tarantula algorithm can be used with test combinations. Is there a book or even an explanation on how this could be useful in the event of a pattern check? with an abstract accessibility graphic?

## Locating abbreviations for prompt date letters MM / DD / YYYY

If a website is located, will users still understand that D = day, M = month, even if these abbreviations are English abbreviations? (global site, public users joe)

## python – Reading and Locating Column Values

I have a .csv file divided into 2 columns with the same number of lines. In the first column, values ​​range from 1 to 8 (which are not in order). In the second column, the values ​​are divided between greater than 1 (> 1) and less than 1 (<1). What I want to do, but I do not know how, is:

Ex: the program reads the first column and takes the values ​​1 (there are several) and sees if the corresponding value in column 2 is greater than or less than 1. Perform this process for all the values ​​in column 1, c & Ie read the first column and get the values ​​2, then the values ​​3 until you read the values ​​8.

In the end, it is expected that something like

The first column value 1 has x values> 1 and y <1

The first column value 2 has x values> 1 and y <1

.
.
.

The first column value 8 has x values> 1 and y <1

## static content – Magento 2.2.6 replacing css files or less or locating the file to modify

I do not know why I find it so difficult, but I have a file that contains css that need to be fixed. The file and the code are in these files:

``````pub / static / frontend / website / my site / en_US / css / styles-l.min.css
var / view_preprocessed / pub / static / frontend / website / my site / en_US / css / styles-l.min.css
``````

The style change I have to do is only on `cashier / basket /` as well as.

I've looked for that same styles-l.min.css file in app / design / frontend / website / mywebsite / but that's not the place to be found.

I know I'm not supposed to edit these files, but when I edit these files directly, I get the desired result … but of course, when I deploy it, it is flushed. How can I make the right change?

It's not really a type of customer, so any help would be greatly appreciated. Thank you.

## python 3.x – Selenium locating elements according to several methods

I use Selenium to locate items in a page. Is it possible to combine two methods together?
Example:

Method 1: driver.find_elements_by_partial_link_text (& # 39; html & # 39;)

Method 2: driver.find_elements_by_class_name (& # 39; iUh30 & # 39;)

Ideally, I will use a method that finds elements that contain both the partial link text and the class name.
