1. Asynchrony is not concurrency
Total comment counts : 35
Summary
The article discusses the crucial distinction between asynchrony, concurrency, and parallelism in programming. Asynchrony allows tasks to run out of order correctly, while concurrency enables multiple tasks to progress simultaneously, and parallelism allows for actual simultaneous execution. The author highlights that misunderstanding these terms has led to inefficiencies and complexities in software development, such as duplication of effort in libraries and poor user experiences. They provide examples to illustrate these concepts and emphasize the importance of recognizing asynchrony’s role without requiring concurrent execution, especially in languages like Zig.

2. Fully homomorphic encryption and the dawn of a private internet
Total comment counts : 30
Summary
Fully Homomorphic Encryption (FHE) enables arbitrary computations on encrypted data without the need for decryption, allowing for full data privacy during transmission and processing. Despite its impressive capabilities, FHE isn’t widely used due to its slow performance, with a current overhead of 1,000x to 10,000x compared to plaintext and high storage requirements. However, advancements are accelerating, with speed improvements of 8x annually, potentially making FHE practical for encrypted cloud computing and confidential blockchain applications. This shift could transform user data handling and enhance online privacy, moving towards “Privacy by default.”
Top 1 Comment Summary
The author discusses Fully Homomorphic Encryption (FHE) and its challenges, noting that while FHE schemes are improving, bootstrapping inherently imposes a significant speed overhead (~1000x), making it unlikely to reach plaintext performance. They highlight the difficulty in promoting hardware acceleration for FHE in an environment where computational resources are focused on large language models (LLMs). Ultimately, they suggest that confidential computing may be a more viable option than FHE for private LLM inference, despite reservations about trusting hardware.
Top 2 Comment Summary
FHE (Fully Homomorphic Encryption) is crucial for protecting privacy, enabling companies to ignore government requests to access encrypted data. Unlike end-to-end encryption, FHE allows companies to process data without ever seeing the plaintext. This reinforces the notion that privacy is a fundamental human right, limiting government power over citizens engaging in democratic activities like voting and free speech.

Total comment counts : 25
Summary
AI capital expenditures (capex) are significantly impacting economic statistics, contributing to GDP growth, and nearing historical peaks seen during the railroad and telecom booms. Currently, AI datacenter spending could reach approximately 2% of U.S. GDP by 2025, a dramatic increase from under 0.1% in 2022. This surge is reallocating funds from other infrastructure, prompting concerns about long-term implications on spending in different sectors. The scale of this private sector “stimulus” contrasts sharply with traditional infrastructure investments, raising questions about its sustainability and future economic consequences.
