Q: Is there a better way to apply a filter over an Either right value?

Julian EspinelSuppose you have an IO (Either String (String, [Int])) and you want to filter the [Int]. Let's say we want to use the following filter: :t filter even Integral a => [a] -> [a] As far as I understand we need to lift this function to be applied to an IO (Either String, (String, [Int])), so I did: ...

htmlizerI develop a CMS-agnostic PHP formatted HTML-CSS "contact now" panel, sticky in the bottom of a website screen. I format it in PHP because PHP supports include which I use a lot to well organize the code. The code is tested and works as can be seen from the following image. I ask a review of the c...

Q: Avoid global variable due to executor.map()

Lucifer UchihaI'm pretty new to python but after watching Mr Robot I felt inspired to make a CLI portscanner. With all the fancy console outputs you see in movies like a progress bar. It's finished and works nicely however I am not very happy with having to write twice global host_IP in main() and scan_tcp(). ...

Q: Rock paper scissors coding assignment

HartonI had a coding assignment to write a Rock Paper Scissors game. The main task is not to show a solution but rather to test the coding style. The rules are such: Problem: rock is "O", paper is "[]", scissors is "8<". George and John play RPC(rock, paper and scissors) a couple of times. I receive 2 ...

Q: Linked List Implementation in C#

Tobi AlafinI wrote an implementation of the Linked list data structure. I mostly did this because it's the simplest collection data structure (at least the simplest to implement), and I wanted to practice implementing IEnumerable<T> and IEnumerator<T>. I also wanted to play around with generics. This was en...

@Duga thats okay
This is a code review site question, but you also need to measure it, and make sure of what you're measuring. Printing to the terminal is really slow, compared to behind the scenes code. Try to "timeit" on the map generation, with no print. — Kenny Ostrom 47 secs ago

@SimonForsberg I create the commands in the place where the user messages come, from the handler of message events
I use the factory in such handler
> Passing both the A and B dependencies to the factory would make sense if that's all that's needed to create the other commands

Exactly, that was what I said, that it doesn't make sense here because that's not the case.
The commands are used when I receive the event of the user's message, which forwards to the command handler that makes use of the factory to find and execute the specified command
Also no this isn't console commands, it's for Discord
Q: Find Kth Element in the merged two sorted arrays?

Aryaman We have been given two sorted arrays and a number K . We have to merge the two sorted arrays in the sorted manner and return the element at the Kth position. My approach is to use two variables which will tell us where are we in the two arrays. Start comparing arr1[arr1_index] with arr2[arr2_in...

I probably should have added that I only been working with web development for less than 1 day. That is why I am asking the community. Good information about the codereview exchange, I didn't know that existed. And good information about the for inside of the while. Not sure why the down votes. Is stackoverflow for learning? Or punishing new developers for trying to learn? — portfoliobuilder 23 secs ago

@L3n Seems kinda pedantic there. Commands entered through a text only medium are commonly called console (text) commands.

Regarding my previous comment, in your case, if "Currently programmers are adding new changes without approval" refers to changes that were not suggested by the code reviewers, then that is a problem. I think better training is in order, otherwise @matt's joke is less of a joke after all. — TTT 26 secs ago

Questions about improving otherwise working code may be better suited for Code Review, but be sure to follow their content guidelines and How to Ask to ensure an on-topic question. As it stands, this question is too broad for Stack Overflow. — jmoerdyk 32 secs ago
hello guys some time ago I made this post which helped me a lot on a RC version.

and the project / library will grow in code and in number of files up to the version 2, I am working on it in github.

I wanted to bring it again for you to review and test it if possible but due to the size I do not know how to make a legible, neat and adequate post.

That would shorten th...
