Hi HN, I started this project because I was tired of BMP libraries that hide allocations, pull half of libc, or solve only one small part of the problem. There are many libbmp-style repos, but the functionality feels…

I recently came across this small ESP32 project and found the design ideas behind it very interesting. BPU (Batch Processing Unit) is a lightweight embedded scheduling core focused on keeping output pipelines stable…

I’m exploring ways to write data from userspace to Linux terminals (stdout/stderr) with minimal CPU cycles, syscall overhead, and binary size, beyond the common methods I’ve considered write(), writev(), splice(),…

For me, Hacker News is probably the best community on the internet. It’s not like others. Take Reddit, for example: at first glance it seems better, with tons of subreddits. But for a beginner, there is no real main…

I built this toolkit with my colleague to dive deep into OS internals and automate the identification of privilege escalation vectors. Written in pure C without external dependencies, it explores everything from Linux…

I recently used Deepseek and when sending another request in "Thinking" mode initially showed activation of "reading" mode, I sent a regular text request without documents so I don't know what that means. Well, I…

I've heard some people bragging about this and saying they use free internet, but I think it's impossible because there's no internet on the phone, even through Termux: aircrack-ng, hashcat etc. I mean, I don't know how…

I built stb_xml because I needed something faster than libxml2 for embedded work – it's a single-header XML parser that parses 1MB XML at 8,700 MB/sec (193× faster than libxml2) while being only 1.5KB (333× smaller). It…

I'm a regular developer, and I'm faced with the question of whether I'm really doing small projects like utilities or libraries - is that correct? I just always thought it's better not to waste time on something big to…

After years of wrestling with verbose bit-twiddling code in embedded projects, I created bitmask.h to solve a simple problem: most bit manipulation libraries are either too heavy (STL-style), too platform-specific…

I was annoyed by reverse engineering binaries and .so traditional tools like objdump, readelf and even strings fail at one critical task: finding numeric constants. Sections .rodata та .dynstr contain only names. That's…

Happy New Year everyone. I’m a programmer, and I just want to wish that the next year will be a bit safer than the last one. Even in 2025, we’ve seen how many risks are still around us in networks, devices, services,…

I searched the official Google website, but there are only old versions that are ~4 years old. But I've heard many people say that he is, so that's what confuses me.

I’m new to Android app modding and still learning the basics. I’m trying to understand how people usually find where premium or paid features are enforced in an app. What kinds of keywords, patterns, or places in the…

Hello HN! I'm developing ASCII Table Editor — a CLI utility in pure C for working with tables in the terminal. It's something between standard console tools and Excel, but without GUI. The utility supports creating,…

Every time I give LLM a big task, he gets lazy and writes a very small amount of code, and doesn't want to do everything in full, here's an example: recently I wrote a program in Python, I needed to translate it C++ but…
