"Game of Rars" – Exploring a New Remote Code Execution Vulnerability in WinRAR with Proof-of-Concept (CVE-2023-40477) https://lnkd.in/e2vfwuq5

Day 10: I managed to find and fix the problematic code in my application at last. Now it works once again! Thanks to the thread library, I can run the scraping operation and the GUI independently. #cpp #softwaredeveloper #bugs #100daysofcode #100daysofcodechallenge

Code coverage is a misleading metric. Even if you have 100% coverage, that doesn't mean your codebase doesn't have bugs. Instead, use the test confidence metric. If you are confident to ship the code to production after all tests are executed, then you have enough tests. But also, the more often you ship, the more confidence you will have in your tests.

Hello connections, Here is my solution to the Daily LeetCoding Challenge for January, Day 24. Problem link: https://lnkd.in/d-WX7saY Github Solution link: https://lnkd.in/dfZ8F7TU LeetCode Solution link (Detailed Explanation): https://lnkd.in/dfh_cnCX Time Complexity - O(n) Space Complexity - O(h), where `h` is the height of the tree. Learning from the problem: The main learning from this problem lies in combining depth-first search (DFS) traversal with bitwise operations to efficiently identify and count pseudo-palindromic paths in a binary tree. The use of XOR operations on the path variable, along with bitwise AND checks for pseudo-palindromic conditions, showcases a creative approach to solving tree-related challenges. #leetcode #problemsolving #cpp #datastructures #happycoding

Updating VS code

Code smells which are often together: 1. primitive obsession 2. if-else/switch branches 3. code duplication How do we beat them? 1. wrap primitive with object 2. factory method/object 3. guards 4. polimorphism Here is a fresh story from our RailsEventStore codebase, when we „just” wanted to cover another ActiveRecord adapter (postgis). https://lnkd.in/dWkwT8au Bonus quest: Do you see how the final code can still be improved?
