How Aurora Blue-Green Upgrades Cut Our Postgres Downtime by 50X

Paxos has implemented Blue-Green upgrades to improve database maintenance for asset trading, achieving a 50-fold reduction in downtime from 30-120 minutes to approximately one minute. This upgrade strategy allows for real-time synchronization between a blue cluster handling production traffic and a new green cluster with the updated version. Challenges included issues with CREATE ROLE statements disrupting upgrades due to temporary roles and the necessity to drop replication slots before PostgreSQL 17, which could lead to data loss. Additionally, upon the green cluster becoming primary, it acquires a new cluster ID, requiring updates for clients using RDS IAM authentication. The transition to PostgreSQL 17 is anticipated to resolve the need to drop logical replication slots, preserving Change Data Capture (CDC) continuity.

Linux running on a PS5 turns it into a Steam Machine that plays PC games

Researcher Andy Nguyen has developed a method to convert a PlayStation 5 into a Linux-based device, similar to a Steam Machine. This modification is only possible on launch-era PS5 consoles running system software version 4.5 or earlier, which dates back to December 2021. The process involves using a specific exploit to boot the operating system from a USB stick or the console's M.2 SSD expansion slot. The setup allows access to Ubuntu 26.04 LTS, utilizing 15GB of memory, all eight cores of the Zen 2 processor at 3.5 GHz, and all 36 compute units of the RDNA 2 GPU at 2.23 GHz. Users can control cooling by increasing fan speeds for overclocking. The output resolution is limited to 1080p, with performance tests showing comparable frame rates to the native PS5 environment for games like Black Myth Wukong, Crimson Desert, and Pragmata. However, issues such as stuttering and artifacting may occur due to the Proton compatibility layer and memory management challenges. This experiment suggests potential for emulation and playing PlayStation 3 games at enhanced settings.

Microsoft enables Hotpatching by default: Windows updates without restarts become a reality

Beginning in May 2026, Microsoft will introduce Hotpatching as a default feature for compatible systems, allowing security updates to be applied without requiring a restart. Hotpatching updates code directly in the memory of running processes, enabling selective updates without interrupting the entire system. It does not replace monthly security updates but alters their activation process on eligible systems, categorized as security updates within the monthly B releases. Eligible systems must be running Windows 11 version 24H2 or newer and possess suitable licenses such as Enterprise, Education, Microsoft 365, or Windows 365. Management of these updates will be facilitated through Windows Autopatch or Microsoft Intune. Microsoft will continue to utilize baseline updates that require a restart, which will alternate with Hotpatch months. Hotpatching aims to reduce the frequency of restarts tied to security updates, particularly benefiting environments where uptime is critical. However, planned restarts will still be necessary, and robust telemetry and maintenance practices will be needed to ensure smooth operation.

Microsoft’s new Windows Update approach could make restarts less annoying

Microsoft is transforming its Windows Update system to reduce user frustration and enhance the experience. The company aims to minimize disruption from updates, promoting a more predictable update rhythm and greater user autonomy. Key changes include a unified monthly restart cycle to avoid multiple restarts, simplified management of updates allowing users to start, stop, or pause updates easily, and the ability to restart or shut down devices without immediate installation of updates. New PCs will allow users to pause updates during the initial setup. However, updates can only be paused for a maximum of 35 days to ensure security and system stability. Additionally, users will receive alerts regarding critical updates, including warnings about the retirement of older Secure Boot certificates.

Vampire Crawlers finds the perfect balance between strategy and automation, and it gives me that Survivors feeling all over again

Vampire Crawlers builds on the mechanics of its predecessor, Vampire Survivors, allowing players to collect and deploy cards with reduced cognitive load during battles. The game features a synergy system that enhances damage output through strategic card selection and mana management. Combat consists of fast-paced waves of enemies, and players can utilize a Play All feature for automation, which can be effective if they have a strong deck. The game is currently featured in the Steam Deckbuilders Fest event.

Microsoft to retire Edge sidebar apps as part of Windows 11 simplification

Microsoft is retiring the sidebar app list feature from its Edge browser, starting with users signed in with a Microsoft account. The ability to add new apps to the sidebar has already been disabled, and existing pinned apps will be removed in a future update. Users will receive notifications prior to the full removal of the feature. Microsoft has not provided a direct replacement for the sidebar app list, and while features like Split Screen remain available, they do not replicate the sidebar's quick-access functionality. Microsoft plans to continue developing its Copilot integration within Edge, despite mixed user responses to the removal of the sidebar app list.

PlayStation 5 Linux Tested: Steam PC vs Native PS5 Games

Linux has been successfully implemented on the PlayStation 5, allowing users to run an open operating system on the console. This implementation, led by security researcher Andy Nguyen (TheFlow), utilizes an exploit for PS5 consoles with system software versions up to 4.5. Users can boot Linux from a USB or SSD, with Ubuntu 26.04 LTS providing around 15GB of usable memory. The PS5's hardware, including its Zen 2 processor and GPU, is fully accessible, with CPU speeds reaching up to 3.5GHz and GPU speeds up to 2.23GHz when boost mode is activated. However, running Linux on the PS5 presents challenges, such as sourcing a unit with the required firmware and limitations in resolution, as users cannot exceed 1080p. Performance tests showed that Linux can match the PS5's performance in some titles, but issues with memory management were noted, leading to stuttering and crashes in certain games. For example, reducing texture quality improved performance in games like Pragmata, while rendering issues were observed in Crimson Desert. The implementation allows for a unique gaming experience, but it also highlights the complexities and limitations of running Linux on a gaming console.
