The following function is an attempt to generate powers of two below the input number max. So powers_of_two_below(15u8, u8::BITS) generates 1, 2, 4, 8. It does calculate 16, but does not include it. This function avoids calculating powers that cause overflow by taking bits as input (since there d...

I want to check if I'm correctly disposing of resources using Ado.NET. I'm not sure when the 'using' statement makes .Dispose() irrelevant. Please bear in mind I'm aware I shouldn't hardcode my SQL commands, this is just for training purposes. Thanks in advance! internal void CreateTable(string...

I'm a new programmer currently coding a javascript alpha-beta pruning minimax algorithm for my chess engine, using Chess.js and Chessboard.js. I've implemented a basic algorithm with move ordering. Currently, it's evaluating around 14000 nodes for 8 seconds, which is way too slow. Is there someth...

Please review the code to categorize some uncategorized objects: const categorizeSimilarTransactions = (transactions) => { if (!(Array.isArray(transactions) && transactions.length)) return []; const uncategorized = []; const categorized = []; const orderIds = transactions.map(t...

I'm studying Dasgupta's "Algorithms". I solved this problem in C++: The garage sale problem. On a given Sunday morning, there are \$n\$ garage sales going on, \$g_{1}, \cdots, g_{n}\$. For each garage sale \$g_{j}\$ , you have an estimate of its value to you, \$v_{j}\$ . For any two garage sales...

As part of an online programming challenge, I wrote a program that implements a stack of integers, supporting adding and removing elements, finding the last inserted element, and the minimum element. The premise is that all methods must be implemented in constant O(1) time. In my code, I opted to...

My intention is to create an API as generic and DRY as possible using Go. To achieve this, I have made some more or less common decisions: To use AJAX call to avoid reloading page when updating the web page. Instead of using Go. To exclude hard coded queries from the API to reduce the endpoints ...

I am refactoring some legacy Python code and thought I'd put the config into it's own file as below. My question is whether I'm trying to be too clever with the last part? Could I just return the dictionary of endpoints and be done with it? The idea for the dictionary is that it could be shared a...

This moves on from Python: best way to setup a config library slightly I have the following code which builds up a dictionary of endpoints that I iterate through later on. Is this the cleanest, most scalable and performant way? I was thinking of adding a list as a key to the library file with key...

I am currently trying to automate API testing using Python. I have stored the API endpoints in a CSV file and read the data through the loop to fire the requests. But I am getting HTTP Error 400. The requested URL is invalid as it's unable to encode the link while extracting the URL from CSV. The...

I would appreciate to have your opinion on this code and whether I can refactor it and make it cleaner, I don't like the fact that I have 3 nested for loops, wi-hich makes the complexity of this code O(n3). categories = {} for k1, v1 in res["relationship_types"].items(): for k2, v...

I have written a piece of code which select each ID whose value equals something, then select a subset for each ID and then work with the subdata. My dataset has over a million entries, thus the code execution is very slow. Am I doing this the most appropriated way ? condition = (df["TYPE_APPEL"]...

I have this code for endpoint in endpoints: if key in endpoints[endpoint]['keys']: yield endpoint pylint suggests iterating it with .items() for parent,child in endpoints.items(): if key in child['keys']: yield child Now when I do, I get a warning about an unused variabl...

If you check the generated code for these functions: int a[]{1, 2, 3, 4, 5, 6, 7, 8}; auto find1(int const v) noexcept { auto p(a); [&]<auto ...I>(std::index_sequence<I...>) noexcept { ((*p == v ? true : (++p, I - I)) || ...); }(std::make_index_sequence<std::size(a)>()); return p...

I have an application where a list of objects must be passed to an SQL stored procedure. The application needs to be aware of the unique ID that is has been given once inserted into the database. My idea is to pass many objects up to a stored procedure using a TVP, keeping it to a single query to...

Is it right to put this code, inside this class, like this? playlist = QMediaPlaylist() url = QUrl.fromLocalFile("music.mp3") playlist.addMedia(QMediaContent(url)) playlist.setPlaybackMode(QMediaPlaylist.Loop) player = QMediaPlayer() player.setPlaylist(playlist) playe...

I have a dictionary that I am writing to a csv file, however I am only writing the values. I want to know if there is a faster way than using a for loop. I am using python 2.7 here is my code. empty = "" with open("parse_data.csv", "w") as f: for key, value in order_dic_keys....

i have made this code to copy a folder to another disk, and it works, but i think there is a better way, the problem is if i don't use the replace, it says the folder exists and it is correct the 'T': is real. Can someone point me to the right path? src = folder_path folder_path_copy = folder_pat...

I use four bools, if true a wall is in that direction bool top = true; bool bottom = true; bool left = true; bool right = true; Then I work through the four and create a wall for each //Create Walls if (top) { GameObject myWallSelection = WallSectionTop[Random.Range...

Make a request to get a token to access some APIs. Use SQL to get a list of users. For each user, need to call 3/4 APIs and store the in...

I have an Android viewmodel for a Fragment that requires the user to perform multiple tasks. In addition to a LiveData object to track the status of each task, I also need a LiveData that tracks a summary of the status of all the tasks.

Background I wanted to write an event loop that supports scheduling, but found that no implementation of priority queue that I know of supports waiting on a condition variable (the idea is that the looping thread will wait on the condition variable and if the wait timed out, it means that it can ...

These commands do what I want, but I'm trying to find out the best approach for this. My main areas of concern are: error handling and disposal of resources. In regards to error handling, I'm catching the errors by wrapping the caller in a try catch. In what concerns to disposal of resources, is ...

I have a lot of Input documents, which contain collections of sentences. I would like to use an online sentiment API to attach sentiments to each of these sentences (how positive or negative the sentence is, on a scale of 0.0 to 1.0). My code returns, for each Input, an Output which contains a mo...

I made a code that simplifies the job of sending anything to print with the windows api. The module has a Document object which stores a reference to the actual device context within it. You can access some of the real dc functions, like Document.dc.Polygon to draw polygons. Any recommendation or...
