High-Resolution Bitmap Graphics with Commodore 64 BASIC 2.0: A Fast Screen Clearing Routine

High-Resolution Bitmap Graphics with Commodore 64 BASIC 2.0: A Fast Screen Clearing Routine

This article demonstrates efficient high-resolution bitmap graphics handling in Commodore 64 BASIC 2.0, focusing on a fast screen clearing routine. The author points out that native BASIC lacks direct bitmap manipulation commands, making conventional clearing slow. A clever solution utilizes the BASIC string storage mechanism: long strings filled with CHR$(0) overwrite the bitmap memory, achieving fast clearing. The technique is illustrated with a cosine function plotting example.

WXT: Next-Gen Web Extension Framework for Accelerated Development

WXT is an open-source tool revolutionizing web extension development. Supporting Chrome, Firefox, Edge, Safari, and all Chromium-based browsers, it builds both Manifest V2 and V3 extensions from a single codebase. Boasting lightning-fast HMR, file-based entry points, and default TypeScript support, WXT offers auto-imports and automated publishing. Framework-agnostic and compatible with any Vite plugin, it features a module system and remote code downloading, maximizing development speed and allowing developers to focus on features, not build scripts.

C++ Compiler Errors: Nonsensical Errors from a Function Declaration

C++ Compiler Errors: Nonsensical Errors from a Function Declaration

A developer adding XAML support to a C++ application encountered a series of compiler errors simply by including the winrt/Windows.UI.Xaml.h header file. The errors stemmed from what appeared to be a normal function declaration: `template struct consume_Windows_UI_Xaml_IExceptionRoutedEventArgs { [[nodiscard]] auto ErrorMessage() const; };` The root cause was a pre-existing macro named ErrorMessage in the developer's project, conflicting with the function name. This macro created an ErrorMessageString object and returned a pointer to an error message string. The macro's lack of boundaries caused the compiler to misinterpret the function declaration as a macro invocation, resulting in errors like "not enough arguments." The solution involved disabling the macro using #pragma undef before including the header or removing the macro entirely and replacing it with an inline function.

ChatGPT Clone in 3000 Bytes of C

2024-12-12

Developer Nicholas Carlini created a ChatGPT clone using only 3000 bytes of C code, powered by the GPT-2 model. This dependency-free implementation loads GPT-2's weight matrix and BPE file, then performs tokenization, matrix operations, transformer inference, and detokenization. While the output quality is not high, its efficiency is remarkable, producing multiple replies per second on modern hardware. This demonstrates the potential of compact code in implementing complex AI models.

QEMU Gains Vulkan Acceleration with VirtIO GPU Driver Update

QEMU version 9.2.0 and later now supports Vulkan acceleration for VirtIO-GPU thanks to the Venus patches. This represents a significant advancement in Vulkan graphics rendering for QEMU virtual machines. The article details the setup process, including installing necessary packages (Linux kernel 6.13+, QEMU 9.2.0+, Vulkan drivers, etc.), building QEMU from source, and creating a VM image. While virt-manager currently lacks Vulkan configuration support, command-line parameters offer a workaround. Troubleshooting tips are provided, along with notes on current limitations in virt-manager and libvirt.

Breakthrough in Reachability Analysis of the Domain Name System

Researchers have presented the first decision procedure for verifying the Domain Name System (DNS), establishing its complexity as 2ExpTime. The study formalizes DNS semantics and uses a novel abstraction based on positive prefix-testable languages, reducing the DNS verification problem to the verification problem for pushdown systems. This approach effectively models attack vectors in DNS, such as amplification attacks and rewrite blackholing, providing a new theoretical foundation for ensuring DNS security and reliability.
