New WAL Archiving Tool ‘pgrwl’ Delivers Zero Data Loss for PostgreSQL in Containerized Environments

The project is a research platform for streaming Write-Ahead Logging (WAL) archiving, focusing on achieving RPO=0 during recovery scenarios in containerized environments. It replicates features of pg_receivewal, including automatic reconnection, streaming into partial files, and error checking. Installation requires a single binary, and debugging can be done with a preferred editor and a Docker container running PostgreSQL. Key features include streaming WAL archiving with replication slots, secure handling of .partial files, support for S3/SFTP backends with optional compression and encryption, a built-in HTTP server for serving WALs, minimal configuration options, and testability through Docker-based integration tests.

Google says Gemini 2.5 models are only getting better with Deep Think and Flash

Google has announced enhancements to its Gemini 2.5 models, including the 2.5 Pro version and the new 2.5 Flash model, which improves speed and efficiency. The 2.5 Pro will include native audio output controls for developers to customize speech. Enhanced security measures will protect against malicious instructions and prompt injection attacks. Project Mariner's functionality will be integrated into Gemini and Vertex AI. Google is also introducing insightful summaries for developers to aid in debugging, along with cost control features through a "thinking budget." A generally available model will be released, and support for Model Context Protocol (MCP) will facilitate the integration of open-source tools into Gemini projects.

Defendnot: A Tool That Disables Windows Defender by Registering as an Antivirus

Cybersecurity developers have created a tool called defendnot, which disables Windows Defender by utilizing undocumented Windows Security Center (WSC) APIs. This tool is a successor to the no-defender project, which was taken down due to DMCA challenges. The developer reverse-engineered WSC’s validation algorithms and identified Taskmgr.exe as a suitable process to host the necessary code. Defendnot persists across reboots by adding itself to Windows autorun and can be managed via a command-line interface with options to disable Windows Defender and Windows Firewall. Unlike its predecessor, defendnot does not use third-party antivirus code. Security experts warn that disabling protection mechanisms should only be done in controlled environments by knowledgeable users.

Software engineer taught Microsoft Copilot to analyze Windows crash dumps

Software engineer Sven Scharmentke, known as Svnscha, has developed an open-source tool called mcp-windbg for crash dump analysis, available on GitHub. This AI-driven tool automates the execution of WinDBG/CDB commands, improving productivity in debugging tasks. Svnscha highlights the challenges faced during development, particularly in creating the interaction layer with Microsoft's Command-Line Console Debugger (CDB). The tool enables natural language crash analysis, contextual debugging, and root cause identification, benefiting software engineers and support teams. However, users are advised that a foundational understanding of debugging principles is necessary to effectively utilize the tool, which serves as a "simple Python wrapper around CDB."
