Solving Fizz Buzz with Cosines

0 CommentsEntertainment

🚀 Read this insightful post from Hacker News 📖 📂 Category: ✅ Key idea: By Susam Pal on 20 Nov 2025 Fizz Buzz is a counting game that has become oddly popular in the world of computer programming as a simple test of basic programming skills. The rules of the game are straightforward. Players say the numbers aloud in order beginning with one. Whenever a number is divisible by 3, they say 'Fizz' instead. If it is divisible by 5, they say 'Buzz'. If it is divisible by both 3 and 5, the player says both 'Fizz' and 'Buzz'. Here…

c++ – Is C++26 getting destructive move semantics?

0 CommentsEntertainment

🔥 Check out this awesome post from Hacker News 📖 📂 Category: 💡 Here’s what you’ll learn: Can I express a function that consumes an object? Meaning that its destructor is not run on the moved-from object? Like the proposed library function trivially_locate_at itself? template T* trivially_relocate_at(T* dst, T* src); Naively, if the library authors can, so should I. Problem: Where is the magic sauce? That function signature does not convey that it effectively destructs an object at src, or the reverse problem, that it effectively constructs an object at dst. I suspect the answer is no: The few examples…

💥 Check out this trending post from Hacker News 📖 📂 Category: 📌 Main takeaway: Tip or TLDR - I built a tiny, zero dependency armv7 userspace emulator in RustI wrote a minimal viable armv7 emulator in 1.3k lines of Rust without any dependencies. It parses and validates a 32-bit arm binary, maps its segments, decodes a subset of arm instructions, translates guest and host memory interactions and forwards arm Linux syscalls into x86-64 System V syscalls.It can run a armv7 hello world binary and does so in 1.9ms (0.015ms for raw emulation without setup), while qemu takes 12.3ms (stinkarm…

0 CommentsEntertainment

🔥 Explore this must-read post from Hacker News 📖 📂 Category: ✅ Here’s what you’ll learn: Providers of operating systems such as Microsoft, Apple, or Google will in the future have to ensure that they have a "youth protection device". This is intended to ensure that porn filters are installed at the fundamental level of PCs, laptops, smart TVs, game consoles, and smartphones, and that age ratings for websites and apps are introduced. This is stipulated by the latest reform of the Interstate Treaty on the Protection of Minors in the Media (Jugendmedienschutz-Staatsvertrag, JMStV), which the state parliaments passed on…

It’s hard to build an oscillator

0 CommentsEntertainment

🚀 Discover this trending post from Hacker News 📖 📂 Category: ✅ Main takeaway: There’s an old electronics joke that if you want to build an oscillator, you should try building an amplifier. One of the fundamental criteria for oscillation is the presence of signal gain; without it, any oscillation is bound to decay, just like a swing that’s no longer being pushed must eventually come to a stop.In reality, circuits with gain can occasionally oscillate by accident, but it’s rather difficult to build a good analog oscillator from scratch. The most common category of oscillators you can find on…
