Ghost: A Database for Our Times?

Ghost, developed by ghost.build, is an "agent-first" Postgres database platform designed for AI-related applications, allowing developers and AI agents to create, fork, inspect, query, manipulate, and delete databases easily. It is free to use and hosted on Ghost’s Cloud infrastructure, making it suitable for testing, prototyping, and disposable database environments. Users can create databases on demand, execute SQL queries, and discard them when finished, contrasting with traditional managed databases. Ghost integrates with AI tools like Codex and Claude Code, providing direct database management capabilities through its MCP server. To install Ghost, users need a supported coding agent and a GitHub account. Installation commands differ for Linux, macOS, and Windows. After installation, users can verify the Ghost MCP server and interact with it through their coding agents. Examples of using Ghost include creating a sales data database, utilizing Ghost CLI commands, and experimenting with databases through AI agents. Ghost allows for rapid database manipulation and is ideal for proofs of concept and experimentation, although caution is advised before using it for production data.

Google’s ‘Pixel Glow’ might have several lights as laptop animation surfaces [Video]

“Pixel Glow” is a forthcoming feature for future Pixel phones that will use subtle light and color on the back of the device to notify users of significant notifications while the phone is face down. It will be compatible with Gemini and will notify users of calls from favorite contacts. The Pixel Diagnostics app includes a “Color LED Check” to test the functionality of the LEDs, which will illuminate in red, green, and blue hues. Google is incorporating eight LEDs for the “Pixel Glow” feature, with a system designed to detect hardware failures. An animation has been discovered that shows an LED strip along the inner edge of an upcoming Pixel laptop, potentially illuminating in colors similar to the Gemini interface.

Constructive Open Sources Agentic DB, the Postgres Memory Layer for AI Agents

Constructive has released agentic-db, an open-source Postgres database aimed at improving AI agents with features like persistent memory, structured knowledge, and hybrid retrieval. This database allows for efficient searching, filtering, and ranking of information, addressing inefficiencies associated with traditional markdown file storage. Key features of agentic-db include long-term memory, conversation tracking, a versioned registry for skills and tools, rules and policies for governance, task orchestration, and runtime observability. It is delivered as a single installable Postgres schema, indexed for multiple retrieval modes, and supports integration with various AI assistants through generated Agent Skills and CLIs. agentic-db is available under the MIT license for local use, with a cloud offering in development for secure, scalable solutions. Developers can access it on npm and GitHub.

You can now run WSL on Windows 95, in case you’re crazy, too

Hailey has developed the Windows 9x Subsystem for Linux (WSL9x), which allows the 6.19 Linux kernel to run on Windows 9x systems without a graphical user interface, relying instead on a terminal experience. WSL9x consists of three main components: a modified Linux kernel that interacts with Windows 9x APIs, a virtual device (VxD) driver that initializes WSL9x and manages userspace events, and a simple 16-bit DOS client for passing commands to the Linux kernel. The system handles syscalls through a general protection fault handler due to limitations in the Win9x architecture. However, this setup poses security risks as both the Linux kernel and Windows kernel operate with the same CPU privileges, meaning instability could occur if either crashes. Comprehensive instructions for installation are available on Hailey's Codeberg page.

How to Profile Modern PC Games with NVIDIA Nsight Graphics

Performance analysis in PC gaming has become more complex with the introduction of DirectX 12 and Vulkan, incorporating technologies like asynchronous compute, hardware ray tracing, and machine learning-assisted denoising. Understanding GPU performance requires advanced tools to analyze workload distribution and shader behavior, with NVIDIA Nsight Graphics being a key resource. NVIDIA Nsight Graphics is a graphics debugger and profiler for modern graphics APIs, featuring the GPU Trace Profiler, which provides detailed insights into GPU execution and performance bottlenecks. Recent updates have improved its utility, including a Flame Graph for the Shader Profiler and support for NVIDIA's DLSS in D3D12 applications. The Peak-Performance-Percentage analysis method focuses on identifying GPU workload constraints and optimizing utilization rather than relying on assumptions about performance bottlenecks. This methodology is applied using Nsight Graphics to analyze GPU traces from the game Cyberpunk 2077, contrasting traditional rasterization with path tracing enhanced by DLSS Ray Reconstruction. The test setup included an Intel Core i7-14700K CPU, 32 GB RAM, and an NVIDIA GeForce RTX 4090 GPU, capturing two scenarios: one with raster-only settings and another with path tracing and DLSS. The analysis revealed that the rasterized frame's most costly aspect was lighting processing, while the path-traced frame showed increased total frame cost and a hybrid workload involving rasterization, ray traversal, and AI-driven processes. Key findings indicated that modern GPU performance is heavily influenced by memory behavior rather than just shader arithmetic, with significant time spent on compute-driven lighting processing and data movement. The analysis also highlighted that ray tracing performance is constrained by memory efficiency, indicating that performance does not scale linearly with RT-core throughput.

GuLoader Leverages Polymorphic Malware and Trusted Cloud Infrastructure to Evade Detection

GuLoader, also known as CloudEye, is a downloader malware that has been active since late 2019, primarily used to fetch and install secondary malware like Remote Access Trojans (RATs) and information stealers. It employs legitimate cloud services such as Google Drive and Microsoft OneDrive to host its malicious payloads, allowing it to evade detection by security tools. GuLoader utilizes advanced techniques including polymorphic code, which alters its appearance to avoid static detection signatures, and exception-based control flow to confuse analysis tools. Over the years, GuLoader has refined its tactics, including the use of software breakpoints and various exception types to redirect its operations. It also employs dynamic XOR encryption to obfuscate internal data, making it difficult for analysts to extract URLs. The malware's continuous evolution poses ongoing challenges for security researchers. Indicators of Compromise (IOCs) include specific hash values for different versions of GuLoader from 2022 to 2024.

Google Translate’s latest upgrade surprised everyone by turning into a chatbot

Google Translate’s new AI-powered Advanced mode can engage in conversation rather than just translating text due to "prompt injection," which causes the model to struggle with distinguishing between translation requests and instructions. Users have found that this mode, based on a Gemini-based large language model, can respond to inquiries rather than providing straightforward translations. The older Classic mode remains a reliable option for consistent translations without unexpected interactions.

After 21 years, GTA: San Andreas speedrunners discover a wild 31-step skip that lets you beat the original PC port in under an hour

A new speedrunning technique for the PC version of GTA: San Andreas allows players to complete the game in under an hour using a method called the Arbitrary Jump in Script (AJS) skip. This technique involves approximately 30 precise steps and was detailed by Reddit user Vitosi4ek. The AJS skip enables speedrunners to execute a JUMP instruction that leads directly to the game's conclusion. The discovery comes 21 years after the game's release, reflecting its lasting popularity and the innovative efforts of the speedrunning community.
