The author discusses the use of `dynamic_cast` in C++ and generally advises against it due to its negative impact on code readability. However, they acknowledge there are situations where using `dynamic_cast` may be justified, particularly in SDKs that evolve over time with versioned interfaces to maintain compatibility. In the example provided, SDK owners use versioning to prevent user code from breaking. They retrieve a basic pointer type (like `void*`) from a DLL, then attempt to cast it to

Subsecond is a Rust library that facilitates hot-patching, enabling developers to modify running applications without needing to restart them. This feature is particularly beneficial for long-running applications like game engines and servers, as it accelerates the edit-compile-run cycle. Subsecond also includes a method called "ThinLinking," which speeds up the compilation of Rust code in development mode, making it useful even outside of hot-patching. The library is designed for simplicity, allowing both application developers and library authors to easily

The article discusses accessing the NFC chip data in a passport using Linux, specifically with a tool called pypassport. The NFC chip, which stores passport information including biometrics, is secured by a password located in the Machine Readable Zone (MRZ) on the passport. This password comprises three data pieces, each with its own checksum, and the entire string also has a checksum, which can be partially lost if the passport is canceled by cutting the MRZ. The author faces a challenge since using

The article discusses a method to expedite and reduce the cost of OpenAI transcriptions by speeding up audio playback. The author recommends using ffmpeg to process audio at 2x or 3x speed before transcription, resulting in fewer tokens used and a shorter waiting time, with minimal impact on transcription quality. The writer shares a personal anecdote about attempting to summarize a 40-minute talk by Andrej Karpathy, during which they mistakenly believed the built-in YouTube auto-transcription feature wasn't available.

The content discusses the differences between improvisational creativity in jazz and structured processes in software development, particularly in modeling sessions. It highlights a phenomenon referred to as “the CTO effect,” where the first person to speak—often a senior leader—dominates the discussion, causing quieter team members to lose their voices. To counteract this, the author recommends starting modeling sessions with 10-15 minutes of silent brainstorming. This allows all team members to generate ideas simultaneously, preventing any single individual from steering the conversation

OpenAI is transitioning its Codex CLI from a TypeScript-based implementation to Rust to enhance performance and address limitations as the tool matured. While the TypeScript version served well for prototyping, it struggled to meet the demands of various use cases. OpenAI will retire the TypeScript CLI, which will still receive bug fixes temporarily, and focus on achieving feature parity with the new Rust build. The shift to Rust, as explained by OpenAI's Fouad Matin, is not ideologically driven;

The discussion around renewable energy costs is often clouded by misinformation aimed at promoting fossil fuels. A key point of contention is whether renewables can lower energy costs. An analysis of ERCOT data from Texas shows that they indeed can. Comparing August 2018 to August 2024, peak electricity demand rose from 65 GW to 80 GW, while solar power production surged from 1.2 GW to 18.8 GW. Despite the increased demand, the wholesale price of electricity in August

A new PNG specification has been released, marking a significant revival of the PNG format after over two decades of stagnation. This update is notable as the PNG format is recommended by major institutions like the U.S. Library of Congress and Canada’s Library and Archives. The new specification introduces High Dynamic Range (HDR) support using only 4 bytes in addition to the standard PNG overhead. Chris Lilley, a co-author of the original PNG, has written about how this HDR feature works. Additionally, animated

Theodore Nichols is advocating for the creation of "thnickels," which are thicker coins intended to offer a heftier feel compared to regular nickels. He has experienced issues, including a dispute with a neighbor regarding a prototype and an incident where burglars did not take him seriously when he defended himself with a bag of nickels. Theodore has set up a minting facility to produce these coins and is taking pre-orders with limited slots available. He has received significant interest through flyers and emphasizes the satisfaction

The content emphasizes the importance of user feedback and highlights an accessible text editor designed for simple needs, inspired by the classic MS-DOS Editor but featuring a modern interface similar to VS Code. Users can download binaries from the Releases page, and the latest version can be installed using WinGet, with the executable named "edit" and an alternative name "msedit." To avoid conflicts with existing commands, it's recommended to use "msedit" instead of "edit," and to assign an "edit" alias

The DRM GPU scheduler is a component of the Direct Rendering Manager (DRM) in the Linux Kernel, utilized by various GPU drivers to manage job submissions from multiple rendering contexts to the GPU. Its key functions include resolving dependencies, detecting timeouts, and crucially, implementing scheduling algorithms to select the next task for execution based on GPU capacity. Different kernel drivers interact with the scheduler in diverse ways; some utilize it primarily for dependency resolution and timeout detection, while others leverage its scheduling capabilities to determine the sequence

The blog post discusses the potential shift away from tokenization in large language models (LLMs) towards more efficient methods that better utilize computational resources and data. It critiques the tokenization process, specifically Byte-Pair Encoding (BPE), which creates a compressed vocabulary by merging frequent token pairs. The authors argue that while tokenization is a common practice in the transformer architecture, it is not a strict necessity and may hinder overall model performance. They advocate for exploring alternatives, such as the Byte Latent Transformer

The author discovers an undocumented easter egg in the original Power Macintosh G3's ROM while exploring its resources using Hex Fiend and a Mac ROM template. This ROM was used in various G3 models from 1997 to 1999. Among the findings, they noted a JPEG image of people who likely worked on the models, previously mentioned by Pierre Dandumont in 2014 but without a method to display it. The author also found a notable clue, a resource named “Native

The author addresses common misconceptions about X11's limitations regarding DPI scaling, fractional scaling, and multiple monitors. To explore these issues, they embark on a project to draw a circle on various screens that maintains a physical size of two inches, regardless of the monitor's size or resolution. They collect multiple screens to test this challenge and employ OpenGL for rendering, though they humorously note that their initial attempt resulted in a color wheel instead of a simple circle. The process involves handling window events and retrieving necessary

The author expresses frustration with using Python for one-off scripts due to dependency management issues, but this has changed with the introduction of the `uv` package manager, written in Rust. `uv` includes a tool called `uvx`, which functions similarly to `npx` for JavaScript, allowing users to run Python tools within a package while automatically handling virtual environments and dependencies. The author references PEP 723, which outlines a metadata format for single-file Python scripts to aid external tools. By
