I created an Arduino compatible checkDevice() function for a circuit designed to enable detecting devices that are plugged in. Essentially testing if a pin is HIGH or LOW and storing up to 8 boolean results into a single Byte Basically, I am now at the point that I would like to turn everythin...

I managed to find a way to rotate a slice in-place (previous question on SO). The slice is linear, but represents a 2d square of elements. Is this approach efficient? Please check the previous question linked above if anything is unclear about the algorithm. Code enum Rotation { Clockwise...

I was looking to replace my use of axios with just fetch, but I didn't like how verbose fetch was with regard to handling JSON output (having to have a separate then call just to return the json). Unfortunately calling text() first to see if it's a JSON response and then only calling json() if so...

I'm learning OS development and have written a single stage bootloader that loads the kernel, enters to protected mode and finally jumps to the kernel. I'll very appreciate any feedback and suggestion about the code. I'll be definitely glad to see any suggestions on my build system (Makefile an...

My today's idea was to create a POSIX shell function to dump all given arguments, typical use would be to call it from a fucntion, where you already know some arguments are not well set (empty; not integer) and this way you can inspect all given arguments in one go. It reminds me of a PHP var_dum...

I am a beginner android developer. I am working on one of my applications. For this application, I wrote an algorithm that is needed to obtain data that is used to build a diagram. I have a list of objects (value, date). For these objects, it is necessary to build a diagram either in the last mon...

I'm trying to write something that can take a description and a date range and return all the dates that satisfy that description. Descriptions can be anything from the following... parsed_tests_dict = [ {"Saturday": [5]}, {"Sunday": [6]}, {"Weekend": [5, 6]}, {"Weekday": [0, ...

class Base: def __init__(self, param): self.prop = val self._validate(param) def _validate(self, param): 'Validation that uses self.prop in its checks' First of all, is it a good practice to set 'self.prop' and make the function use it, or pass it to the function? And if I want t...

I am working in a system that does not have room for an STL, however I do like the comfort of std::function. For now I am only using this to wrap lambdas, but some sort of std::bind replacement is also on the roadmap. Lets look at the usage first: function<void (bool)> _click_callback; ...

I am learning Rust. I have written a web crawler that would scrape all the pages from my own blog (which is running on Ghost) and would generate a static version of it. Because of this, I'm not interested in handling robots.txt or having rate limiting. extern crate select; use std::io::Read; us...

I would like to execute two database queries concurrently for quicker response time. Since channels seemed to be too verbose, I came up with the solution below. However, I'm not very confident about it and wanted to head your opinion and ask if there is a better solution for this. Thank you. var...

I'm trying to optimize my FilterArray function so I've thought to use the sorted column (when available). The original function loops through all items in the array, make comparison in various columns and build the resulting array. In this new version, I want to reduce the number of main loop's...

Here is the part of code and it's kind of long so I do not place the entire here. The program is called BP, and it allows users run 3 at the same time. Therefore, I want some reviews on the performance. Thanks. //structure part //Needed Functions in BP void bg(string, char* arg[]); void bgList(...

I've started learning C++ using Microsoft Visual Studio. I'm decided to create a simple GUI program that creates a "snowflake" wherever the user clicks on the screen. Seeing as how this is my first C++ program, I would greatly appreciate feedback on any aspect of my code. snowflakes.cpp // Decl...

I have implemented Dijkstra's algorithm in C++, but it seems a bit complicated since I really tried to follow the process of the algorithm as much as I could. If there's any simplification you would suggest, I would really appreciate, because this task was only for me to get familiarized with thi...
