3 Tips For Making a Popular Open Source Project in 2024 [Ultimate Guide]

Fancy watching this as a video instead? Click below: Introduction I have around ~10k GitHub stars. I’ve come up with a bullet-pointed actionable list of how to make open-source projects popular. One of the projects I created had 67 lines of code and had only existed for 3 days

Packaging Your Rust Code

Packaging Your Rust Code

I recently went through the trouble of distributing a Rust package. I wished that there was a simple guide on distributing one package to many platforms, so I wrote this guide. Follow me as we publish my package, RustScan, to multiple distributions. Semantic Versioning Semantic Versioning is a system defining

Divide and Conquer Algorithms with Python Examples

Divide and Conquer Algorithms with Python Examples

Often I’ll hear about how you can optimise a for loop to be faster or how switch statements are faster than if statements. Most computers have over 1 core, with the ability to support multiple threads. Before worrying about optimising for loops or if statements try to attack your

Ripgrep cheatsheet

Tip: Use match statements instead of hash maps

Tip: Use match statements instead of hash maps

Hashmaps are often touted as the fastest way to store & lookup data. They have O(1) constant time lookup, which means no matter what you look up it will always take the same amount of time. Whereas other search algorithms (Binary Search, for instance) take O(log n) time,

An Algorithm for Finding Anagrams

An Algorithm for Finding Anagrams

Finding anagrams of words does not look like a difficult problem but has an interesting solution. An anagram is a word or sentence that can be transformed into another word or sentence. Elvis has all the same letters as Lives, so Elvis is an anagram of Lives. The way most
