clunk | Clunk - real-time binaural sound generation library

I am trying to show multiple sets of different polylines (each set represents one cycling route with its own start and endpoint).

There are ten routes in total I am bringing in from a JSON file. The problem is the map is consolidating all the individual ten routes into one mammoth polyline.

So It is sort of connecting them all together (you can just make out the very straight line connecting between each route and only one startCap and endCap icon).

I would expect/want to see ten different startCap and endCap icons and spaces between each polyline set.

So how do I make the map show each polyline route as distinct routes?

I am using flutter_polyline_points to decode the polyline route to the google map.

Code below and the JSON is on the live link to make it easy to emulate if that helps.

In essence in terms of steps :

1. I create the google map and have one main central marker on it.

2. I then bring in ten routes from a JSON file. These are ten objects in an array called Segments. Each object has a unique id I use for the PolyLineid and a unique polyline set of points in a string. So I bring in the JSON and then.

3. iterate over each object and decode the polyline string to polyline coordinates which I attempt to then add to the map as multiple PolyLines.

Also to here is the output I am seeing to bring the issue to life.

I have a 2D array in which I need each 'column' (axis=1) to be treated independently. For each column (1D array) I need a function applied to each length tail of the 1D array, to provide an array of length N as follows. How do I make it faster? Perhaps by removing the for loop. I was doing this with map/lambda/hstack until I hit a divide by zero error, which required the if/elif/else conditions to eliminate the march to infinity.

So I'm just starting out teaching myself JS from a cheesy textbook and there's a challenge to figure out what this code does:

I downloaded a TTF font called "Clunk" and I'm trying to apply it to some text.

Here's the code I'm using:

I am a very beginner in JavaScript and recently I am studying it on a book. I am trying to modify a script from this book that passes a number which is the number of letters in a word, and output the number of combinations of words you would get by scrambling the letters. While the original script lets you pass the number I want to modify it and allow the user to input a word, take it and return the number of words by scrambling the letters. My issue is that, when I run the code, I keep getting this error:

Uncaught TypeError: Cannot read property 'length' of undefined at thingamajig

Why is this happening?

I am developing a graphic viewer where you can mark pictures inside a given directory to redirect them to another folder. This is supposed to help sorting large clunks of unorganized pictures into smaller folders.

My problem is I don't know how to get the picture's when the only information I have is the path of the Directory they are inside. I found something called DirectorySearcher Class but since I am new I do not know how to implement this in my program or if it will even help.

If you know how to implement it(should it really be useful) or any other method to achieve my goal please tell me.

Thanks for reading.
