Fast vs. Slow System Calls: How Signals Wake Up Blocked System Calls

2025-06-03

This article delves into the core differences between fast and slow system calls in operating systems. Fast system calls (like `getpid()`) return immediately, while slow system calls (like `read()`) may block waiting for external events. The article focuses on how signals interrupt blocked slow system calls, demonstrating with code examples how to handle `EINTR` errors and use the `SA_RESTART` flag. It also explores the nuances of disk I/O and how the kernel handles different system call types, comparing the strengths and weaknesses of various I/O models (blocking I/O, non-blocking I/O, I/O multiplexing, signal-driven I/O, asynchronous I/O, and I/O Uring).

US Anti-Piracy Symposium Pushes for Site Blocking

2025-01-29

A recent USPTO anti-piracy symposium highlighted the need for site blocking in the US. Experts discussed the evolution of piracy into a sophisticated, multi-level industry offering "piracy as a service." The brazen behavior of some pirates, openly advertising and even trademarking their services, further emphasizes the urgency. While site blocking is effective in over 50 countries, the US lags behind, partly due to the 2012 SOPA failure. The symposium advocated for a dynamic US site-blocking system, learning from international examples to avoid overblocking and swiftly target new pirate domains.

Meta Secretly Leaks Private AI Chats: A Privacy Nightmare

The Mozilla community accuses Meta of secretly using private AI chat conversations as public content, unbeknownst to many users. They demand Meta shut down the Discover feed until real privacy protections are in place; make all AI interactions private by default with no public sharing option unless explicitly enabled; provide full transparency on how many users unknowingly shared private information; create a universal, easy-to-use opt-out system preventing data use for AI training; and notify all users whose conversations may have been made public, allowing them to permanently delete content. Meta is blurring the lines between private and public, jeopardizing user privacy.

California's Net Neutrality Law Survives Federal Ruling

Despite the overturning of the Federal Communications Commission's (FCC) attempt to regulate broadband internet service, state laws in California, New York, and elsewhere remain intact. This week's ruling by the 6th U.S. Circuit Court of Appeals striking down the FCC's open internet rules has little bearing on state laws enacted during the years-long tug-of-war over the government's power to regulate internet service providers. Experts suggest this ruling, along with other decisions and the Supreme Court's stance on a separate New York case, has effectively solidified state regulators' efforts to fill the void. California boasts one of the nation's strongest net neutrality laws, signed into law in 2018, preventing anti-competitive practices deemed harmful to consumers. The law has survived legal challenges and prompted changes in how internet service providers offer plans and services.

PDF Parsing: A Battle Against the Spec

2025-08-04

Parsing a PDF seems straightforward: find the version header, cross-reference table, object offsets, and finally build the catalog dictionary. Reality, however, is brutal. The PDF specification is not a hard and fast rule; real-world files are full of non-compliant situations, such as incorrect `startxref` pointer locations, garbage data at the beginning of the file, and malformed cross-reference tables. The author, by analyzing a large number of real PDF files, reveals these problems and points out that existing PDF viewers work because they handle non-compliant situations. This article explains the challenges of PDF parsing in an easy-to-understand way and provides valuable experience for developers.

Double Detonation: A New Theory for Type Ia Supernovae

Double Detonation: A New Theory for Type Ia Supernovae

The origin of Type Ia supernovae has long puzzled astronomers. The traditional view involves a white dwarf accreting mass until it reaches the Chandrasekhar limit, triggering an explosion. However, observations suggest a higher frequency than this mechanism predicts. A promising new theory, the 'double detonation' model, suggests that helium accumulating on a white dwarf's surface fuses (first detonation), triggering the fusion of carbon and oxygen in the core (second detonation), leading to a supernova. This bypasses the need for the Chandrasekhar limit, potentially explaining the observed frequency, but the rapid succession of explosions and complex environment make observational verification challenging.

YouTube's New Anti-Adblock Technique: Fake Buffering and How to Bypass It

2025-06-20

YouTube has rolled out another round of anti-adblock measures, one of which is "fake buffering." Videos experience artificially long buffering at the start, proportional to the ad duration. This is because YouTube's InnerTube API, when adblocking is detected, returns video streams from GVS (Google Video Services) with delays. The author found a solution by modifying a uBlock Origin filter to add `isInlinePlaybackNoAd: true` to the JSON request. However, YouTube implemented a locker script, necessitating a workaround by hooking Object.assign.
