verse | Text transformations | Data Manipulation library

Much like the title says. I have followed my class tutorials but chunks seem to be missing and it gets a bit confusing flicking between video lectures and pdf's when you're not too well versed in such.

When the app is executed the user can search for a song by year, or display all records within the database. However, originally all records would display from clicking the search by year button instead of the display all button. The search function works as intended but the display all button I cannot seem to figure out, despite following my lecturer's tutorials.

The first section of code is "MainActivity.java" and the second is "OpenDatabse.java"

I have three nested v-for loops:

I want to write a simple desktop application to track the overtime work of our employees. Whenever one of our employees needs to perform some tasks outside our normal working hours we want to track them using "Kimai Time Tracking".

The application I am programming needs to get the duration of all recorded tasks from Kimai, add them up and store them on a local SQL Server as an overtime contingent for the employee to claim later.

This is the GET request I'm mainly gonna use:

GET /api/timesheets (Returns a collection of timesheet records)

and this is an example output from the Kimai Demo (Sorry for length)

I have a multidimensional array called verses:

Seems like this should be easy, but I'm really struggling here. I'm not well versed on Linux but I can get around. I just setup a new Ubuntu v20.04.2 Server and installed Apache2 on it. I then installed VSFTPD on it as well.

Now I'm trying to get it so when I login with user "remote" that I'm locked into the /var/www/html/ directory, but have write access to anything inside.

my vsftpd.conf file has the following uncommented settings:

In my app, the user chooses the chapter he wants to read, the verse he wants to begin from, and the end verse.

I'm going to store these three strings and show in his "reading history" list, where he can see all of his previous readings.

I read that you can do that by creating a class, storing these in an object and converting it to JSON then storing it inside sharedprefs.(or something like that). But I didn't understand them as they were a little different from my case.

this is the class:

I have a dataframe named grouped_train which lists the number of sales of each item in each store by month. Here's an example of the dataframe.

date_block_num item_id shop_id item_cnt_month 0 32 0 6 0 32 5 1 0 26 1 3 0 26 18 9 1 32 46 1 1 26 50 2

There are 33 date_block_nums which correspond to different months. I'd like to add two columns which list the sum of all sales by item_id in the previous month/date_block_num as well as the mean of sales for that particular item_id from all store_ids in the previous month, any rows where date_block_num == 0 should be None.

So, using the example df above, the output would look like:

date_block_num item_id shop_id item_cnt_month item_sales_prev_month mean_item_sales_prev_month 0 32 0 6 None None 0 32 5 1 None None 0 26 1 3 None None 0 26 18 9 None None 1 32 46 1 7 3.5 1 26 50 2 12 6

I've written some code for just the sum_item_prev_month column which I believe works and could easily change it to create the mean sales column as well, but with over 2.9 million rows in my dataframe, my code takes multiple hours to run. Admittedly, I'm not well versed with pandas, there has to be some vectorized formula I'm missing to speed up this computation. Here's the code I have so far.

I'm more versed in python/R than excel but this requires an excel specific solution, would love the guidance here!

I have a excel in the following form

So I'm not that well versed in linear algebra so I'm struggling with this.

I have a unit vectors v. I want to find two angles(angle 1, rotation around x-axis, and angle 2, rotation around z-axis) such that when I rotate v by them it aligns the vector v with the y-axis. From this question I have a function that can find the angle between arbitrary vectors and returns a rotation. But this function returns 3 angles. Essentially there is an infinite number of 3d rotation that aligns v with the y-axis so I want the two unique angles.

This the code I have now, it requires numpy and scipy:
