Recommended Hosting for Forge Servers: Minecraft Recipes Guide

In heavily modded Forge servers in Minecraft, recipe management is crucial due to the extensive crafting systems introduced by various mods. Players can encounter tens of thousands of recipes, especially in complex modpacks that combine technology, magic, farming, and automation. Crafting advanced machines requires a network of smaller components, leading to significant server load during crafting operations. Automation increases demands on servers, as multiple systems may run concurrently, generating thousands of crafting events every minute. Server performance is influenced more by CPU speed than by RAM, with high-frequency processors facilitating quicker recipe evaluations. Effective hosting configurations should include powerful CPUs and fast storage to maintain tick stability. Regular server management practices, such as avoiding large automated crafting loops and scheduling restarts, can enhance performance. Keeping mods updated and testing new ones before deployment can help prevent recipe conflicts and maintain stability.

Generating Referentially Consistent Synthetic Test Data for PostgreSQL in .NET Application Modernization

Satyajit Gokhale, Aiswaryaa Venugopalan, Ruchi Agarwal, Nits Jeganathan, Khurram Khawaja, Vijay Mandadi, and Luke Huan contributed to this article. AWS Transform offers a .NET application modernization service that allows enterprise customers to migrate from Microsoft SQL Server to Amazon Aurora PostgreSQL Compatible Edition. This migration reduces licensing costs and enhances scalability while utilizing an open-source ecosystem. Schema conversion tools can assist in translating DDL to PostgreSQL-compatible definitions, but correctness must be verified by teams to ensure performance under real-world workloads. Traditional testing methods, such as using production data or manual checks, are not scalable and raise privacy concerns. Therefore, there is a need for realistic synthetic data generated at scale that adheres to the migrated schema's constraints. AWS Transform for SQL Server modernization employs an AI agent to generate constraint-respecting synthetic data at scale during the migration workflow. This process involves loading the PostgreSQL schema into a live database, constructing a dependency graph for data generation, and distributing tasks across multiple sub-agents. The agent validates each generated INSERT against the live database, ensuring compliance with constraints and providing error diagnostics for any violations. The synthetic data generation workflow consists of four stages: schema analysis, establishing generation order, distributing tasks across sub-agents, and validation with error recovery. The agent extracts metadata from the PostgreSQL schema, determines a valid table generation sequence, parallelizes data generation while maintaining referential integrity, and generates and validates data row-by-row against the live database. Each successful insertion enriches the context for subsequent generations, while errors are handled through structured diagnostics and iterative regeneration. The process ensures referential integrity and preserves the generation state, allowing for recovery from interruptions without data loss.

Proof-of-concept exploit released for Certighost Windows AD CS vulnerability

A proof-of-concept exploit for a vulnerability in Windows Active Directory Certificate Services (AD CS), identified as CVE-2026-54121, has emerged, allowing authenticated attackers to compromise an entire Windows domain. Microsoft addressed this vulnerability in its July 2026 security updates. The flaw enables attackers to manipulate machine account attributes, obtaining certificates to impersonate critical domain controllers and execute privileged Active Directory operations. Researchers H0j3n and Aniq Fakhrul discovered the vulnerability and publicly disclosed it with a functional exploit that exploits a fallback mechanism in AD CS. This exploit can automate the extraction of sensitive credentials through a DCSync attack. Microsoft has since implemented additional validation measures to enhance security against this vulnerability.

AI taught to design efficient farms in Minecraft – mathematical modeling and constraints are used

The emergence of virtual assistants in gaming, particularly in agricultural simulation within Minecraft, enhances the gaming experience by providing players with instructions and explanations for farming tasks. A developer named Serranegra has created an AI tool that optimizes farm construction by generating an optimal arrangement of blocks based on player input regarding terrain and desired crops. For example, the AI's solution for sugarcane cultivation increases yield from 54 to 61 units while improving land utilization from 66.7% to 75.3%, representing a 13% efficiency increase. However, the tool's benefits vary by crop, with negligible gains for some, such as cacti and wheat. Serranegra has made the source code of the "optifarm" project publicly available on GitHub for collaboration.

New Certighost PoC exploit lets attackers hijack Windows domains

A proof-of-concept exploit for the "Certighost" vulnerability (CVE-2026-54121) has been released, affecting Windows Active Directory Certificate Services. This vulnerability allows authenticated attackers to compromise a Windows domain by manipulating machine account attributes to obtain certificates from AD CS, enabling them to authenticate as that machine or even as a domain controller. The flaw was reported to Microsoft on May 14, 2026, and addressed in the July 2026 Patch Tuesday updates. The vulnerability exploits a fallback mechanism in AD CS during certificate enrollment requests, allowing attackers to direct the Certification Authority to their controlled systems. The researchers demonstrated that a low-privileged user could create a machine account and use it to impersonate a domain controller, leading to potential domain compromise. Microsoft has added validation to the chase process in the July updates to prevent this exploitation. For those unable to install the updates, a temporary workaround involves disabling the chase fallback, though this has not been extensively tested.

I Built My Second ETL Pipeline. This Time, I Started Thinking Like a Data Engineer

The author transitioned from a data analyst role to a data engineer, creating a 12-month self-study roadmap focused on learning by building projects. The first project was a GitHub ETL pipeline, which evolved from a simple Python script to a more complex system using SQLite and GitHub Actions for automation. The author realized that the challenges of data engineering lay in system design and orchestration rather than just writing ETL logic. For the second project, the author built an automated RSS ingestion pipeline to explore engineering decisions in creating a reliable data pipeline. The project emphasized the importance of separating application responsibilities from orchestration tasks, leading to the use of Docker for consistent execution environments and Kestra for orchestration. The author validated each component of the project incrementally: first the Python ETL, then PostgreSQL, followed by Docker, and finally Kestra. This approach ensured that each layer functioned correctly before adding complexity. The final architecture included distinct responsibilities for each component: Python for data processing, PostgreSQL for data storage, Docker for execution, and Kestra for orchestration. The author learned that effective engineering involves considering system reliability, error handling, and observability, shifting the focus from merely writing code to designing entire systems. The experience transformed the author's mindset, emphasizing the importance of incremental building and the separation of execution and orchestration responsibilities.
