Episode1 | Lions , Pandas , and Zookeepers | Data Manipulation library

I'm working on a dataframe with guests in tv-talkshows. It kind of looks like this:

I'm trying to take a few png images add them an enumerated grid and save them each image by itself as a single tiff file

the output I get is, first image with grid and numbers as required,

the first image is shorter then the others if that matters

other images are only numbered but without a grid

this is my code

I need to rename multiple files at once. Lets say I have a these files:

I have a collection named measurements. In this collection, there are only three fields: id (univoque), tmstamp (univoque) and value. Each row which contains a value greater than 0 is considered an alert. All the alerts that occur from the zero state to the next zero state is considered an episode. I want to query the data in such way that it returns it in episodes format. That is to say, each row is an episode.

In order to make it easier to understand, I'll put an example:

here is a piece of the xml data before i go any further

The cell in the DataGrid correctly updates if I change the value of the property in the code, but the value of the property does not change if I modify the value in the cell itself. In fact, if I modify the value in the cell, it immediately returns to the value it was set to before that.

I'm working on an app where you can set TV episode rating data, and I'm using this datagrid for that purpose. Here is the relevant XAML:

I have a main view controller called as HomeController(). There is a grouped table view with three sections. The first section should display data from my JSON file. To give an Idea, I want to display a list of tv series seasons like season1, season2, season3 in my first section.

If a user clicks on season 1, a new view controller will be pushed which contains a table view with rows displaying the titles of season 1 episodes. If user taps on an episode, again a new VC will be pushed where it will display the episode title in UILabel and episode summary in a text view.

Currently I'm passing static data like below

I have a bunch of jquery functions that I know would be better utilized in a for loop, but every time I try to set it up, it doesn't work.

Here is what I want the for loop to do:

I am trying to sort a large arraylist of objects for my podcast app. This is a Wear OS app so most devices have much less memory and processing speed than a normal modern Android device. Loading episodes in the correct order isn't very noticeable in podcasts with a small amount, but ones with hundreds of episodes take up to 10 seconds to sort. How can I speed this up?

I thought about sorting the episodes and saving them in the correct order in my sqlite database, but all episodes are stored in their own table. I'm guessing I should have saved dates as milliseconds rather than a string. I imagine there would have been a smarter way to store them initially, but now they will just be in the order they were found in all the users databases.

What can I do to speed up this process? Should I just do this in the background?
