The author discusses the ongoing efforts to integrate reflection, a significant language feature, into C++26, highlighting two key components: P2996, which focuses on the foundational aspects of reflection, and P3294, which addresses code generation. The author references a statement by Andrei Alexandrescu regarding the limited utility of introspection without code generation. They contrast C++'s current reliance on C macros for code generation—which are problematic due to their lack of hygiene and primitive nature—with Rust's robust

At the beginning of the year, the author explored how DOS managed the memory limitations of the x86 architecture's real mode through various tricks. A critical, unanswered question was about the different "models" offered by compilers of that era, such as Borland Turbo C++, which included options like tiny, small, medium, compact, large, and huge. The author seeks to decode the significance and implications of these options, particularly in light of modern 64-bit computing with abundant memory. To understand

The content discusses a Boulder Dash-inspired game created in x86_64 assembly for Linux, which operates without any libraries, relying solely on the Linux system call interface. The game requires installation of git-lfs to access its data files and needs nasm version 2.16.03 (not 2.15 due to a bug). Users must ensure they have permission to write to /dev/fb0 by adding their user to the video group. Before playing, users should switch to TTY mode

Georgia and John McGinty from New Jersey sustained serious injuries in an Uber crash and have been denied the right to sue the company due to terms they accepted via the app. A state ruling indicated they confirmed their agreement to Uber's terms on multiple occasions, including a time when their daughter accepted them. The McGintys assert they did not realize this meant they were giving up their right to a legal trial. Uber stated that their terms require disputes to be resolved through arbitration, which typically leads to

The content discusses the disparity between the pricing of physical and digital games, highlighting that digital purchases don't grant true ownership, as services like Steam can shut down, leaving users without access to their games. It raises concerns about the potential loss of older games, citing examples like Atari cartridges and abandoned titles. The author's frustration is directed at companies for their high prices and tendency to monetize games through subscriptions and microtransactions, while also noting that piracy, though not theft, is a reaction to these practices. They emphasize

Dockworkers at ports across the United States, from Maine to Texas, initiated a strike on Tuesday over wage disputes and the issue of automation, which could lead to inflation and shortages if prolonged. The strike, marking the International Longshoremen’s Association's first since 1977, began after the contract for about 45,000 workers expired. Following the start of picketing at various ports, local union leaders emphasized their demand for a fair contract that protects jobs against automation. The union, having seen

In this post, the author outlines a method for setting up a local Kubernetes cluster using Kind, Terraform, and Kftray. The focus is on keeping all services internal to the cluster, thus avoiding the complexities and security risks associated with exposing services externally. Instead, kubectl's port-forwarding feature will be utilized, automated via Kftray for easy access to internal services. The prerequisites for the setup include Docker, Terraform (v1.9.5), and Kftray (available in
