QUESTION
How to set "status" is 'UP' when the result of column "CountID" change from 0 to >= 1 by google script
I have 2 sheets, main sheet have table below, raw data sheet have raw data auto refresh every hour.
Column "CountID" from main sheet count id from raw data sheet using arrayfomula and CountA function. =arrayformula(COUNTIF('raw data'!A2:A11,A2:A))
In my official spreadsheet, the column index may change therefore, I must use the column header ("Status", "Count") to refer to column position.
"Status" column from main sheet using data validation dropdown list with up to 6 value like: (Cancel, Pending, UP, DOWN, Return ...)
Testing sheet: Testing sheet
The code below working and I just upgrade for column header reference to ensure script working when column index change.
Thanks
Jacques-Guzel Heron.
ANSWER
Answered 2022-Jan-27 at 11:16You can develop a fast Apps Script project easily to update the Status column of your Sheet by using installable triggers. I will show you how in the example below. I chose to run the trigger every half an hour with the everyMinutes method, but you can adapt it to your needs. First you would have to run the createTrigger function once to create the trigger. Then the function updateStatus will run automatically every half hour. Please check the SpreadsheetApp class to learn more about the applied methods.

I'm a beginner in C and have this problem: I'm supposed to make an app where you insert the coordinates of a triangle's vertices, and then it prints details about its area, perimeter and most interesting of all, it's supposed to print its angles. The code is supposed to be written using the double tangent equation from Heron's formula. I've tried doing it using atan(), but I guess I should add +n to avoid going out of the domain. Don't know how though.
Here's the equation. And below is my code:

For my class assignment I am working on code that uses loops utilizing Heron's method to find an estimate of the square root while also displaying the iteration and relative change.
I have the following code:
...ANSWER
Answered 2021-Sep-27 at 00:43You need to make the following changes to your code:
- the second line in your function should be
x.append(0.5*(x0 + a/x0)). You need the average of x and a/x (as in every other iteration). - the
printstatement should be executed before theif/elseblock to print the last line where your relative change falls below the tolerance.

I am using MongoDB with a Node API and one route needs to return a summary count of each type in a collection.
I am not using the MongoDB Aggregate pipelines because the data I need has already been sent to the API for other summary statistics in the same route.
Note: I have put the _id's below in single quotes for ease of use but they are mongoose.Schema.Types.ObjectId's.
So, given that I have an array of mongo objects like this:

Answered 2021-Jul-05 at 14:58There are multiple ways to do this, but the basic logic is doing a groupBy and match with lookup table. It would be easier to do with lodash or a helper library. But also without using JS it can be done pretty easily.
For a quick solution u can use this:

QUESTION
Official Flink Documentation states that for each core in your cpu, you have to allocate 1 slot and increase the parallelism level by one simultaneously.
One of my custom operators requires more than 1 CPU for computing (It is how it works in Heron). My system's cpu is 2.5. But Flink only uses 1 cpu. Do you know how can I config the Flink to use more CPU with only 1 slot?
...ANSWER
Answered 2020-Dec-18 at 10:25"One slot per core" is merely a rule of thumb. Nothing enforces this.
Each subtask (an instance of an operator chain) is single-threaded, but the slots within a task manager, and the task managers within a machine or container, will use all of the resources made available to them.

...ANSWER
Answered 2020-Nov-12 at 01:28char letters[8][20] = …; defines an array with automatic storage duration. Memory is reserved for it only during the function call. The statement return (str); returns a pointer to an element of this array, and then the memory is no longer reserved for the array. In C’s abstract model of computing, the array ceases to exist. In typical practice, the array is on the stack, but the printf call overwrites it.
You can fix this by defining the array with static storage duration, which reserves memory for it during all of program execution:
