Compile-Time Sorting in C++ With Templates: Why Heapsort Falls Apart
14+ hour, 31+ min ago (613+ words) Tried implementing sorting algorithms as pure template metaprogramming. Not constexpr, not consteval. The old way, where the compiler does the sorting during template instantiation and the "output" is a type. Quicksort worked. Mergesort worked. Heapsort turned into selection sort. That…...
" The Case of the Vanishing Digits: Why 123, 456 = 64?
2+ day, 7+ hour ago (279+ words) That is a great idea! Acknowledging the mentors who helped you understand a concept adds a nice personal touch and builds community. Since you're currently working through his DBMS playlist and following his roadmap, it fits perfectly. Here is the…...
I Built malloc() from Scratch in C " Here's What Went Wrong
2+ day, 12+ hour ago (219+ words) I decided to implement my own memory allocator in C to understand it better. This wasn't for production use, just to learn how allocation, fragmentation, and concurrency actually behave in practice. I also benchmarked it against glibc's malloc to see…...
Data Structures | Computing (9569) | GCE A-Level - Higher 2 (H2)
4+ day, 9+ hour ago (909+ words) Don't worry if some of these concepts seem abstract at first. We'll use plenty of real-world analogies to make them stick. Let's dive in! A Stack is a linear data structure that follows the LIFO principle: Last-In, First-Out. Analogy: Think…...
Your Struct is Wasting Memory and You Don't Know It
4+ day, 12+ min ago (1337+ words) We write structs by listing fields in whatever order feels readable. Name, then age, then score. It compiles. It runs. The compiler silently bloats it, misaligns it, or both, and you ship it without ever checking. Here are three structs…...

The Problems with C++ and Its Evolutionary Dead End
4+ day, 19+ hour ago (409+ words) This explains why new "C++ killers" appear regularly. Almost every new systems programming language has at some point been promoted as a successor: safer memory model, better concurrency, clearer errors, and a more modern development experience. Many of them are…...
Pattern: sliding window (Variable window)
