rxx | Minimal framework for react rxjs mvi architecture | Reactive Programming library

I've got many files with names like the following format:

File name Revision_Series.random_obs1.random_obs2-random_obs3.txt

The idea would be to strip everything from Revision_Series until the file extension.

Revision_Series will always have the format Rxx where xx is 2 digits.

Costea Voda 4A R03.Showed-Unliked.Has4Changes.zip

Costea Voda 4A R11.Showed-Liked.Is.Final.zip

which should become

Costea Voda 4A R03.zip

Costea Voda 4A R11.zip

I'm working with spss code. I'd like to print RXX result that was computed by spss to console(output file). Is there in spss any possible way to do this?

Code shown below:

I have to write a program in AVR assembly that takes in a pointer to an integer array when being called by a C program and performs operations on its elements without actually outputting values. For simplicity's sake, let's say I want my program to double the value of each element - Such that given the array {2, 4, 6, 8}, calling a print method in C separately from what I wrote will print {4, 8, 12, 16}.

My problem is I don't understand how to alter the values of the array's elements and have those changes persist after the function doing so has finished executing. I can't return anything through register r24, because I need to return a different number for a different purpose.

My idea was, since the input on register r24 comes in as a pointer to the first element of the array, I would mov r26 r24, associating(?) the array with the X pointer, and then ld that to another register so that I can use the X pointer to increment through the array, as in ld r18, X+.

And while I have little trouble navigating the array, I don't understand how to give my changes permanence, if that makes sense. I'm under the impression that I'm expected to use st and/or sts to solve this, but I'm struggling to understand how they work. My attempt was to reserve a pointer like Z to be associated with the input array, and every time I had a value ready to replace an old element in the array, I would write st Z+, rXX, putting the value at index Z and subsequently pointing to the next index. This didn't work, so I'm left wondering: what do I need to do to link the memory of my local registers with that of the inputs provided to the program?

I need to request 3 items from a user then,

1. Request the price of those three items from a user
2. Calculate the total of all three
3. Calculate the average
4. print a statement saying "the total of product 1, product 2, product 3 is xxxx and the average is xxxx

I've tried to use 6 strings (so 3 for the products and 3 for the prices) so I could call each value separately. But then I was told an array would greatly shorten the code and neaten it up so I tried that but I'm battling to call it forward. I know how to work out the average and total but I'm struggling with the array part.

I currently have an Observable that is, in fact, a sequence of chunks of a source file, using this method.

It "chunkifies" the stream as a sequence of byte[].

The problem is that, given this sequence, I would like to write it to a destination stream. In other words, I have to dump each byte[] to a file stream until the sequence is finished, but also, I should await until the sequence finishes.

So far, this code I created works, but I'm afraid it's not the correct way to do it way to do it. The relevant part in which the IObservable is handled is the Download method.

I have an array with words, some ending with special characters. I would like all the special characters at the end of the words to be deleted. Is there an elegant way to do it?

I have a project that I created in Visual Studio. I created a GIT repository, cloned it down to my computer and copied the VS project into it. Now I am doing some learning on that test app.

I made a change to a file like this and did a commit:

I am trying to exchange the token that was given to me by the amazon cognito for a role that is defined on Identity pool, using "assume_role_with_web_identity" of boto3 but it gives me this error:

"botocore.exceptions.ClientError: An error occurred (AccessDenied) when calling the AssumeRoleWithWebIdentity operation: Access denied"

I must have missed something on the policy?

I already tried to change the policy for the lambda, to this:

I have written the code in R (see below). It works when N=100. I need to run the dist_statistic function N=1000 times.

Inside this function, the Cholesky decomposition is used implicitly. For the Cholesky decomposition, the matrix must be positive definite. But the elements of the i-th matrix are random numbers. I do not control positiveness. As the result I see the error:
