The long-division algorithm is either boring or funny, depending on your viewpoint. The code itself, written in C-like syntax, implements long division for N-bit unsigned integers, playing with shifts and bitwise operations. The proof of correctness is demonstrated via Hoare logic using axioms for assignments, composition, conditionals, and while-loops. Finding the right loop invariant is […]

In this study, we introduce FFTNet, a novel spectral filtering framework that utilizes Fast Fourier Transform (FFT) to achieve global token mixing in a more efficient manner compared to conventional self-attention mechanisms. By leveraging the frequency domain, FFTNet efficiently captures long-range dependencies while dynamically emphasizing salient frequency components through a learnable spectral filter and modReLU […]
This WebAssembly runtime is unique because it is implemented purely in TypeScript types, allowing you to turn C code or WebAssembly into TypeScript types without any JavaScript runtime code. Surprisingly, it can run Doom, defying expectations. The repo is described as an “active crime scene” with the murder weapon still unknown. The author, @dimitropoulos, has […]
Author explores the debate around the demise of the USSR, focusing on the role of entrenched interests. Some argue powerful bureaucratic forces made reform impossible, while others claim the reform process was botched. Assessing Gorbachev’s role, some say he was weak, while others argue he wielded significant power. The essay delves into the General Secretary’s […]
In the midst of the Cold War, the XB-70 Valkyrie was unveiled as a bold replacement for the B-52, designed to be the ultimate weapon of mass destruction. As the son of a GE engineer who worked on the project, the author shares his father’s journey from a farm boy in Indiana to an integral […]
The rise of AI-generated history videos on TikTok has captivated millions, offering a unique first-person perspective of historical events like the Black Death and the eruption of Vesuvius. While creators like Dan and Hogne aim to spark curiosity, historians like Dr. Boyington raise concerns about inaccuracies, calling some videos “amateurish” and “sensational.” The debate centers […]
The author discusses the effectiveness of using LLMs for listwise document ranking, particularly in the context of locating N-day vulnerabilities through patch diffing. They highlight that this technique simplifies complex security engineering tasks by reframing them as document ranking problems. The surprising aspect is the demonstration that GPT-4o mini can efficiently locate specific functions fixing […]
The author shared a solution they found for an issue encountered while using Visual Code Insiders. They provided detailed steps on fixing the problem by editing the extensions.json file. By removing a specific object from the file, the issue was resolved, and the program started working again. This information may be helpful for others facing […]
ggwave is a tiny data-over-sound library that enables communication between air-gapped devices using sound. It implements a simple FSK-based transmission protocol with a bandwidth rate of 8-16 bytes/sec. Error correction codes are used for robustness. The library is versatile, suitable for various projects, and can be integrated with different audio backends. Examples include serverless file […]
Optifye.ai, a Y Combinator company, faced backlash for using AI-powered security cameras in factories to monitor workers. The demo video showed a supervisor calling out a low-performing worker, sparking controversy on social media platforms like X and Hacker News. Some criticized it as “sweatshops-as-a-service” while others defended it. The rise of AI in the workplace […]
