I've built a read/write lock and have been testing it without encountering any problems. It was made to avoid writer starvation, but I believe it works against reader starvation as well. I've seen alternatives online, but was wondering if this is a solid implementation. If you use a normal shared...

Is this a correct way to copy elements from array origin to array location? #include <stdio.h> void copy(const int *origin, int *location, int n){ int i; for(i=0;i<n;i++){ location[i]=origin[i]; } }

I implemented a simple snake clone in C++, using SDL2 for the graphics part. Gameplay-wise, its pretty much classic snake: The player is able to control the snake with "WASD", food gets spawned randomly and if you eat it, you gain speed and length. The game is lost once you collide with yourself....

The code j...

I am writing a piece of code for C# Web Api, letting the clients to pass a column name and sort direction as parameter. Although there are, like, 30-ish properties, so the following code (despite it works) gets ugly after a while. What are my options to avoid repeating this seemingly same pieces ...

I'm "playing" with ARM assembly on a Raspberry Pi, reading various tutorials and posts to help - no, it's not a college assignment, I'm too old for college! I'm pleased with getting the following code to take a decimal value (between 0 and 255) and output the binary string equivalent to the scree...

I use Argo Workflows to dispatch lists of jobs defined in a CSV. I accomplish this by chaining a bunch templates together, which involves: Breaking up the CSV file into individual JSON objects Parsing the JSON into parameters Actually passing the parameters to individual pods The YAML which acc...

I am doing the Assignment 1 part c from MIT OCW. The question is to find a percent of monthly income saved so that you can pay the down payment in 36 months. My code: salary=float(input("Enter your annual salary: ")) cost = 1000000 semi_annual_raise = 0.07 low = 0 high = 10000 down=0.25*cost #d...

This is my attempt of implementing an efficient, cache-friendly, vector for polymorphic objects. From now on I will refer to "virtual functions" as functions which are dependent on an object's underlying dynamic type, though they might not be strictly marked "virtual". MEMORY MODEL OF POLYMORPHIC...

I got an initial array, I am checking against another array to find how many objects have at least one instance of the Domain in data. I wonder if there is a more performant way to achieve the same goal. const data = [ { Domain: 'google.com', '# Reocurring Domains': 0 }, { D...

So, I wanted to make a function which will return nth prime number when calling it for the nth time(it should return 2 when I call it for the first time, 5 when I call it for the second time, then 11...). I had a problem with this until I discovered static int which solved my problem. Since I am ...

I made a very simple interpreter of the untyped lambda calculus in Coq. I'm still very new with formal methods and I'm sure I'm doing a lot of things very wrong. The spec is also very very weak currently. For example, a bug with the stack fully permitted by the spec caused an infinite loop. Fulle...
