Benzene at 200

Published: 2025-06-16 | Origin: Hacker News

Benzene, a compound first isolated by Michael Faraday in 1825, is celebrated for its significant impact on chemistry and various industries. Faraday discovered benzene while examining the components of illuminating gas, noting its aromatic smell and unique properties that defied simple chemical classification. Its stability and distinctive cyclic structure were not understood until later in the 19th century. Benzene, a colorless and volatile liquid, became a crucial solvent due to its ability to dissolve nonpolar substances. Its re

How fast can the RPython GC allocate?

Published: 2025-06-16 | Origin: /r/programming

The author, CF Bolz-Tereick, conducted a study on the performance of the RPython garbage collector (GC) regarding object allocation times. To investigate this, they created a benchmark program that continuously allocates instances of a class while preventing the RPython static optimizer from removing allocations by keeping multiple instances alive. Each instance occupies 16 bytes on a 64-bit architecture, consisting of the object's data and GC metadata. The author notes that while this method slightly increases workload, it effectively measures allocation

Python is removing GIL, gradually, so how to use a no-GIL Python now?

Published: 2025-06-15 | Origin: /r/programming

The Global Interpreter Lock (GIL) in Python is a contentious feature that simplifies language design but also limits the performance of multi-threaded programs on multi-core CPUs, contributing to the perception that "Python is slow." However, a significant change is on the horizon: proposed PEP 703 aims to gradually remove the GIL over the coming years. The article discusses the GIL's history, its current implications, and future outlook, while also providing a beginner-friendly guide on how to set up and

Improving my previous OpenRewrite recipe

Published: 2025-06-15 | Origin: /r/programming

Last week, the author explored OpenRewrite by creating a Kotlin recipe that organizes files according to official directory structure guidelines. They plan to enhance the recipe by automatically computing the root package instead of requiring users to set it manually. In pure Kotlin projects, files should align with the package structure while omitting the common root package, placing code directly under the source root. The original recipe required users to specify the root package, but the author intends to automate this process by analyzing source files to determine the longest prefix

Modifying an HDMI dummy plug's EDID using a Raspberry Pi

Published: 2025-06-15 | Origin: Hacker News

The author needed to change the monitor that a cheap HDMI "dummy plug" emulated from a 4K display to a simpler one without 4K support. Dummy plugs are small devices that trick a computer into thinking a monitor is connected by mimicking the necessary video signal circuitry. They contain an EEPROM chip with Extended Display Identification Data (EDID), which holds information about the supposed monitor’s characteristics. The author's objective was to replace the dummy plug’s EDID with one from a 1080
