millisec | Prettify milliseconds with customizable format | Runtime Evironment library

I have run into what seems like a common problem in svelte but haven't found a good solution. I have a function that is called when a button is pressed in a component, the basic situation is shown below.

I have written

I have some data from event producer. In a "created_at column I have mixed type of datetime value.

Some NA, some ISO8601 like, some POSIX with and without millisec.

I build a func that should take care of everything meanning let's NA and ISO8601 info as it is, and convert POSIX date to ISO8601.

I want to clear the interval when stop button is clicked it seems the clearInterval is not working there as expected. The timer doesn't stop when handleStop function is triggered or when handleReset id triggered

Here's what I am trying to do:

I came across the code below for implementing sorting array.

I have applied to a very long array and it was able to do so in under a sec may be 20 millisec or less.

I have been reading about Algorithm complexity and the Big O notation and would like to know:

1. Which is the sorting method (of the existing ones) that is implemented in this code.
2. What is the complexity of the algorithm used here.
3. If you were to improve the algorithm/ code below what would you alter.

I have written out code to allow for an 8051 Microcontroller to be able to interface with an LCD and display a temperature that is read as an 8bit binary value on the LCD. The code was working when and was able to display text on the LCD however, when introducing code to allow for the temperature to be read, the program breaks. The error seems to be centralised around the function that reads the temperature from the ADC and seems to be about '_asm' which is something I have never dealt with before. The errors are listed below:

When I test the following code with #define N 100 , there's no error accures. But I change it into #define N 1000, error show's that fish: “./file” terminated by signal SIGSEGV (Address boundary error). Can somebody help? I'v tried to find answers from google, but I can't understand other's solutions which since to be same error different problem.... I know that multiply two matrix can work in a large amount such as 1000*1000 matrix. But I'm new to learn this multiply matrix.

I have a stream of nodes and a stream of edges that represent consecutive updates of a graph and I want to build patterns composed of nodes and edges using multiple joins in series. Let's suppose I want to match a pattern like: (node1) --[edge1]--> (node2).
My idea is to join the stream of nodes with the stream of edges in order to compose a stream of sub-patterns of type (node1) --[edge1]-->. Then take the resulting stream and join it with the stream of nodes another time in order to compose the final pattern (node1) --[edge1]--> (node2). Filterings on the particular type of nodes and edges are not important.

So I have nodes, edges and patterns structured in Avro format:

I have been struggling with a bit of bash code to generate an mp4chaps.chapters.txt file based on the time length of mp3 files so that when I have converted it to an audiobook (m4b) I can add the chapter information again.

I think I have solved it but I am curious if this can be done more elegantly?

My poc code (assumes that there are mp3 files in the folder you run this script in):
