Hacktoberfest's update

PRs count if: Submitted in a repo with the hacktoberfest topic AND during the month of October AND ( The PR is merged OR The PR is labelled as hacktoberfest-accepted by a maintainer OR The PR has been approved ) https://hacktoberfest.digitalocean.com/hacktoberfest-update

[cclauss]

PSA: I am checking out for the month of Hacktoberfest. I have some important work that I must attend to so I will stop contributing to this repo for the next 30 days. I would encourage maintainers to stick with the rules that have gotten us this far: be friendly, insist on best coding practices including all that is in CONTRIBUTING.md (functions, type hints, doctests, etc.)

If you see PRs that are useless or show that the contributor has not read CONTRIBUTING.md please mark those PRs with the invalid label and close them. (Hacktoberfest organizers look for the invalid label.) Do the same for any contributor who is disrespectful. If we consistently demonstrate that we have high standards and no tolerance for disrespect then the spamers will go elsewhere.

See you again in November.

[poyea]

Please observe that, from now on, a PR has to be marked hacktoberfest-accepted, approved or merged in order to be counted towards the event. For maintainers, please add the labels hacktoberfest-accepted to PRs that are NOT spams, even if you can't review those PRs at the moment. As usual, we label spams as invalid.

Hi @poyea , Mark please issue #2402 as resolved in the first message of that issue.

[poyea]

Sure.

[thevirtualbuddy]

Hi @poyea & other maintainers, I am interested to contribute one of my projects to this repository. The project is a simple CLI application (python based) which has the following functionalities:

1. Encrypt and encode data in an image.
2. Decode and decrypt data from an image.

It uses Caesar cipher (encryption & decryption) and Image Steganography(encoding & decoding).

Can I contribute it to this repository?

[poyea]

Yes. You may also see if there's any related implementation in ciphers.

[thevirtualbuddy]

@poyea Thank you for the quick response. It has caesar cipher #1958 but it doesn't have image steganography combined with it. So, should I work on the existing code or work fresh?

Or should I create a new folder as Image Steganography?

[poyea]

You may add a new one, as the current one works with strings, unless you can modify it make it compatible with images or matrices.

[thevirtualbuddy]

Thank you @poyea I will add a new folder as Image Steganography.

[cclauss]

Please create a new directory only if there are going to be multiple Python files in it. If it is just a single Python file then please find and existing directory to put it in. We do not want to force visitors to click into and out of tons of directories to find something of interest.

[poyea]

Yes, add a folder if you have images related to that, but in general, we want to avoid this.

[thevirtualbuddy]

I am a bit confused here now :'). If I should add it in Ciphers as caesar_ciphers_with_steganography or create a new folder?

[cclauss]

How many Python files will your proposed new folder contain?

[thevirtualbuddy]

@cclauss I can combine all the files in a single file. Right now, I have the files divided as caesar.py, steganography.py and driver.py So, only one file.

[cclauss]

Cool. Then do it whichever way that you think best. Thanks.

[MonarchChakri]

Hi @cclauss / @poyea Added file_utils.py under others and created a PR https://github.com/TheAlgorithms/Python/pull/2735 A utility files helpful for all common file IO. Please review and merge.

[dickyw71]

Hi @poyea & other maintainers,

I have a fix for issue #1901 and I would like to submit.

My YAML Workflow file auto-closes empty issues. The file-path name is .github/workflows/auto_close_empty_issues.yml.

The workflow checks whether a new issue body is empty and if so it uses the close-issue action to auto-close the issue and send a notification email to the repo owner/maintainers.

I have tested the Workflow works as expected in my own repo.

Is is ok for me to raise a PR?

[FirePing32]

Hey @cclauss @poyea Can i add some chemical conversitions to /conversions as a part of hacktoberfest ?

[breezko]

I’ve added #2782

[dhruvmanila]

As mentioned, please include for Hacktoberfest or something like that in your description to signal us that this PR is for Hacktoberfest otherwise we wouldn't know that you participated or not.

[dhruvmanila]

@cclauss @poyea Should we add #2786 and #2695 to Hacktoberfest?

[FirePing32]

@dhruvmanila yeah....for hacktober fest....I am making a PR for conversions

[ChiragBolakani]

Hey @poyea and other maintainers, I would like to contribute to the web_programming folder with a webscraper which will allow users to scrape presentations and then download them.

[gupta-niharika]

Hey I'd like to work on one of the issues. I'm a first timer

[poyea]

Hey @cclauss @poyea Can i add some chemical conversitions to /conversions as a part of hacktoberfest ?

We'd love to see that.

[poyea]

@cclauss @poyea Should we add #2786 and #2695 to Hacktoberfest?

If the work is original and non-trivial, we should put the tag on it. Ideally, all non-spam PRs should be tagged. Of course, it would be even better if the build passes at the same time.

[mandloiaditi]

Hi, I would like to implement DSW algorithm to balance binary search tree. May I take up this task and add the implementation to data_structures/binary_tree folder ?

[FirePing32]

I have created a PR https://github.com/TheAlgorithms/Python/pull/2944 @cclauss @poyea . I have added molecular_chemistry algorithm in /conversions.

[Satyamkumarai]

Hi @poyea I'd like to contribute to Python/maths/factors.py as part of hactoberfest I have implemented a fast prime no Generator function Can i Create a PR?

[verdantfire]

I want to add the implementations of Operating Systems scheduling algorithms. Should I add features upon the basic algorithm structure written by @cclauss (to maintain consistency) or use my own?

[SimonLammer]

I've opened the PR #2916, is there anything I still have to do moving forward?

[radadiyamohit81]

Hello @poyea, I would like to contribute to your repository that I have build one Deep Neural Network (Research Work) for greater accuracy . Can I contribute it to this repository?

[KmrAnish04]

Hello @poyea, I am beginner to this programming and open source world and I have not much knowledge about DS/Algo but I want to contribute to this repository. So I have some python3.7 scripting program, can I add my program to "other" directory of this repository. I will be thankful by contributing to this repository. Regards, Anish

[TheSussex]

Hi @poyea I'd like to add a Number Guess python algorithm to the repository, can I go ahead?

[Ed1123]

Hi, this'd be my first PR to a public repo so I'd like to keep it very small (very). I'm starting by improving the documentation for this two algorithms (newton_method.py and newton_raphson.py).

I know it is a small contribution and know that it may not count towards Hacktoberfest. If you have any feedback on how to make it count I'm all ears eyes. 😄 If there is no way it can count it'd ok. It will serve me to get familiarized with how Github and PR's work (I'm following this tutorial by DigitalOcean for that).

[sumitmohite0501]

Divide and Conqrer added #3202. all chechpoint pass

Hi @poyea, I came across with an implementation of the secand method in which many improvements can be done. Should I just modify that file or add a new algorithm?

[KaLiMaLi555]

Hi, I wanted to add a implementation for a Data-structure called KD-Tree. It has various uses like multi-dimensional partitioning and searching. Is it a nice idea? If so where should I add it?

[dark00infinity]

solution of euler problem38 added #3452 . all checkpoint pass

[cybov]

Can someone pls look into my PR #3420

[shabab477]

@cclauss, @poyea could you look into 3468

[skhurana852]

Hi, I would like to add implementation for Banker's Algorithm which is a deadlock detection algorithm that uses 2d arrays. Can I contribute?

[BasilVictor]

@poyea or any of the other project maintainers, I have created a program and have created a PR, but there has been no response of any sort 😔 Can someone review #3512 and give any feedback if any, so that even I can contribute here.

[cclauss]

@BasilVictor There are 460+ open PRs on this repo and before Hacktoberfest started there were 30. All maintainers are snowed under with the silliness of Hacktoberfest on a set of tasks that we do for no remuneration.

Is your algorithm (#3512) really differentiated from / better than the four pages of other distance algorithms in this repo? You have checked the box I have read CONTRIBUTING.md. but your submission contains no type hints, no doctests, a function name that is not in snake_case, and no URL to a source describing the algorithm.

[GGn0]

Hello maintainers! I think there might be a problem with the PR #3110 One of the two Travis CI checks seems to be still in progress (for over 16 days!) but clicking the details shows that the build passed after 19 minutes here's a link to the build

[SOUMEE2000]

Hello @cclauss. This is my first time contributing to anything. So basically, I submitted three PR s that are for the c language directory. A stupid question, but can they be thought of as participating for hactoberfest?

[shabab477]

@dhruvmanila @cclauss, @poyea could you look into 3468. Thanks!
