I created numbase is an alternative to Base64 that encodes data into a single large number instead of ASCII characters. It's useful if you want to store or transmit data in numeric form and easily apply compression algorithms like Huffman.GitHub: https://github.com/Ferki-git-creator/numbase
Added: · Enhanced safety features: Comprehensive bounds checking throughout the codebase· New error codes: Added GIF_ERROR_BUFFER_OVERFLOW and GIF_ERROR_INVALID_LZW_CODE· Error message utility: New gif_get_error_string() function for descriptive error messages· Built-in testing framework: Comprehensive test suite enabled with GIF_TEST macro· Test runner function: gif_run_tests() for easy...
I've been working on a C library that combines the best features of Fortran's multi-dimensional arrays with NumPy's expressiveness and Julia's performance.Key features:· Fortran-style column-major arrays with A[i,j] indexing· NumPy-like operations (element-wise math, slicing, broadcasting)· Memory-safe allocation/deallocation· Efficient views instead of copies for slicing operations· Linear...
I used to make normal libraries - the hype quickly disappeared. And here I made something in 20 minutes, without fanaticism, and got 21 upvotes HN sometimes really works randomly.
This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with:- Stack operations (push/pop/dup/swap/over/drop) - Arithmetic (+, -, *, /) - Output (., emit, cr) - Stack inspection (.s, depth)Example usage: Stack s; stack_init(&s); dict_init(); exec(&s, "10 20 + ."); // Prints "30" exec(&s, "1 2 3 4...
Hi HN, I want to share my updated FSP (Find Similar Patterns) v2 text compression algorithm. I tested it on a non-trivial excerpt from Romeo and Juliet, and it achieved impressive results: original size 437 bytes, compressed size 358 bytes, compression ratio 1.22. Unlike traditional methods like LZMA or Huffman, FSP v2 searches for repeating 3–5 character patterns, storing references (REF)...

Hey HN, I’m trying to level up my productivity while working remotely. What’s one trick, habit, or tool that dramatically improved your workflow? Looking for actionable tips, not just generic advice.
GitHub: https://github.com/Ferki-git-creator/STB-Style-Single-File-C...Lightweight single-header JSON parser/generator for C/C++ in STB tradition. Implements RFC 8259 (JSON), RFC 6901 (JSON Pointer), RFC 6902 (JSON Patch), and RFC 7386 (Merge Patch). Zero dependencies, thread-safe, UTF-8 validation, file I/O, minification, and custom allocators. Ideal for embedded systems and cross-platform...
That said, it can serve as a basis:
On ESP32, you could adapt it to use LWIP sockets via ESP-IDF or Arduino, implement non-blocking I/O with FreeRTOS tasks, and reduce buffer sizes.
On bare-metal, it would require a lightweight TCP/IP stack (like lwIP or uIP) and rewriting functions to be fully event-driven and minimal on dynamic memory.
Also, please keep in mind this was the first version — mainly to see if the library idea resonates. I didn’t plan to make it fully optimized or MCU-ready yet. Future versions will definitely include improvements for embedded environments.
