Critical PHP PDO Driver Bugs Expose Firebird SQL Injection and PostgreSQL DoS Risks

A recent examination of PHP's database driver layer revealed two significant vulnerabilities in PHP Data Objects (PDO) affecting the pdo_firebird and pdo_pgsql drivers. The first vulnerability, CVE-2026-25289, allows SQL injection attacks through NUL byte manipulation in quoted strings, compromising the safety of SQL statements. The second vulnerability, CVE-2026-25290, can cause application crashes due to null pointer dereferencing when invalid multibyte character sequences are processed. Both vulnerabilities stem from assumptions about C string handling and have been addressed in a security release. Researchers recommend treating binary input as untrustworthy and encapsulating financial workflows within atomic transactions.

From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley, where they were advised to focus on analytics rather than OLTP databases, which were considered a solved problem. However, upon developing Databricks, they found that OLTP databases were cumbersome, challenging to scale, and fragile. This led to the creation of Lakebase, a serverless Postgres database designed to address these issues by externalizing the write-ahead log (WAL) and data files into independent services. Lakebase architecture separates the WAL into a distributed service called SafeKeeper and data files into another service called PageServer, allowing for improved durability, scalability, and performance. This architecture eliminates data loss risks associated with disk failures and misconfigurations, simplifies high availability, and allows for elastic compute resources. Lakebase also introduces LTAP (Lake Transactional/Analytical Processing), which enables transactions and analytics to operate on a single data copy in real-time, avoiding the need for separate data copies and reducing costs. The system retains Postgres's ACID semantics while storing data in open columnar formats, making it accessible to both transactional and analytical engines without the delays and complexities of traditional replication methods. The architecture allows for unlimited storage, serverless compute, and instant branching, while ensuring that analytics can read the most current transactional data without affecting transactional workloads. LTAP aims to unify transactional and analytical processing by leveraging distinct compute engines for each workload while integrating at the storage layer.

15 years later, the PS2 gets a Minecraft port, and it actually hits 30fps

The Sony PlayStation 2 is the highest-selling gaming console ever, with sales exceeding 160 million units. Minecraft is the most sold non-arcade video game, second only to Tetris in overall sales. Minecraft was never officially released on the PS2, but a developer has successfully ported Minecraft Pocket Edition version 0.6 to the PS2, allowing it to run without modded hardware. The port achieves frame rates exceeding 30fps despite the PS2's limitations, using a custom "OpenGL adaptor" and various strategies to manage the console's 32MB of RAM. The optimized version of the game is called OptiCraft.

Microsoft Open-Sources PostgreSQL Extension for In-Database Durable Execution

Microsoft has introduced pg_durable, a PostgreSQL extension that enables developers to execute durable workflows within the database, reducing the need for external orchestration systems. It simplifies workflow management by allowing developers to express long-running, fault-tolerant SQL functions directly in SQL, managing execution concerns like retries and recovery. Workflows are defined in SQL, with the extension handling retry states, progress tracking, and checkpointing. A pg_durable function operates as a graph of SQL steps that can resume from the last durable checkpoint after a failure. The extension preserves execution states within PostgreSQL tables, ensuring workflows can withstand crashes and restarts. It includes a domain-specific language (DSL) for scheduling and parallel execution. An example of a durable function is provided, demonstrating sequential and parallel execution using specific operators. pg_durable is particularly useful for vector embedding pipelines and scheduled maintenance tasks. Architecturally, it consists of a PostgreSQL extension and a background worker built on Rust libraries, without any external control plane. Durable execution allows long-running workflows to automatically resume from failure points, simplifying distributed system architecture.

TeamViewer integrates Windows AI VSR into Assist AR

TeamViewer is collaborating with Microsoft to integrate on-device artificial intelligence through the Windows AI API in its Assist AR product for frontline workers. The new Video Super Resolution (VSR) feature, announced at Microsoft Ignite 2025, enhances video quality by reconstructing and sharpening incoming video streams on the receiving Windows device, which helps reduce artifacts and optimize bandwidth usage. This feature is particularly useful for remote supporters dealing with weak or unstable mobile connections, improving the efficiency of remote assistance.

‘This world means so much to us’: Overwatch’s game director celebrates its 10 year anniversary by mapping out how it all began

Team 4 is celebrating the tenth anniversary of Overwatch with nostalgic game modes, exclusive cosmetics, and loot boxes. Game director Aaron Keller shared that development began in mid-2013 after the cancellation of Project Titan. He revealed that some concepts from the abandoned project influenced Overwatch, including character Cole Cassidy. The team had a limited time to pitch Overwatch and focused on seamless information delivery in gameplay, such as health indicators and sound cues. Character designs were initially met with skepticism but later generated excitement. Iconic maps like King's Row and Throne of Anubis were developed, with Anubis being the first completed map after extensive conceptual work. Keller expressed gratitude to the community for their support over the past decade.

Трёхмерная реконструкция аварий на трассе А-7: Патерна, Пикассент и Торрент

The operation "Exit" in Valencia province led to three simultaneous accidents on the A-7 highway, causing over six kilometers of traffic congestion. Accident analysts utilize three-dimensional documentation, including digital photogrammetry and laser scanning (LiDAR), to accurately capture collision points and vehicle trajectories. This data helps determine liability and structural deficiencies. The 3D models created allow for the calculation of impact speeds and simulation of vehicle interactions. Additionally, these technologies enable predictive simulations to test modifications for traffic management and improve safety measures, ultimately aiming to reduce accident rates on busy corridors.

Review: Pragmata PC Review: Path Tracing Is A Game Changer

Path tracing scalability is maximized on the RTX 5090 with 4K DLSS quality mode, while the RTX 5070 can achieve a commendable experience using optimized settings at 1440p DLSS balanced mode. The RTX 5070 is the most prevalent Blackwell GPU according to the Steam Hardware Survey, indicating that path tracing is becoming mainstream. Optimal performance in Pragmata on an 8GB GPU requires selecting the lowest texture quality setting due to bugs and potential stuttering with medium settings. Higher mesh quality settings may reduce geometry on 8GB cards. Optimized settings for Pragmata include various configurations for ray tracing, texture quality, and shadow quality, closely mirroring developer settings for current-generation consoles. Enabling the shadow cache option significantly improves frame rates by reusing existing shadow data.
