Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

Improving your Windows Insider experience

The Windows Insider Program is undergoing changes to improve user experience based on feedback from the community. The channel structure will be simplified into two main options: Experimental and Beta. The Experimental channel will provide early access to features under development, while the Beta channel will showcase features planned for near-term release without gradual rollouts. Users will have the option to select specific Windows core versions and enable or disable features through a new Feature flags page. Additionally, transitioning between channels will now allow for in-place upgrades, preserving apps and settings, except when moving from Experimental Future Platforms. All Insiders will be transitioned to either the new Beta or Experimental channel, with specific transitions outlined for current users in the Beta, Dev, and Canary channels. Commercial customers will see similar changes, while those in the Windows Server Insider Program will not experience alterations.

Google’s New $3 USB Kit Converts Old Windows 10 PCs to ChromeOS Flex Machines

Google, in collaboration with Back Market, has launched a USB kit for installing ChromeOS Flex on aging Windows 10 PCs for a fee. This kit simplifies the installation process, allowing users to replace their existing Windows system easily. ChromeOS Flex is compatible with various PCs and some Macs, focusing on cloud-based tasks and supporting browser-based and Android applications only. A study indicated that ChromeOS consumes 19% less energy than similar systems. For every USB drive produced, an equivalent weight of electronic waste is recycled. Google plans to provide software updates for Chromebooks for 10 years and for Pixel phones for 7 years. Windows 10 support will end in October 2025, with Microsoft offering a free extended security update until October 2026. Approximately 32% of the market still uses Windows 10, with 121 million enterprise devices estimated to be operating on it. The ChromeOS Flex USB Kit is considered a pilot program, with potential for increased production based on demand.

Minecraft Movie 2: What do we know so far about the sequel

A sequel to A Minecraft Movie is in development, with a release date set for July 23, 2027. Mojang is collaborating with Warner Bros Pictures, and filming is scheduled to begin in April 2026 in New Zealand. The original cast, including Jack Black, Jason Momoa, Sebastian Hansen, Emma Myers, and Danielle Brooks, will return, and Kirsten Dunst will join as Alex, the first female default character skin from Minecraft. The plot is speculated to involve enchantments or a journey to The End, with hints from a teaser poster featuring glowing purple pickaxes.

PostgreSQL logical replication: How to replicate only the data that you need

Many organizations using PostgreSQL face challenges in replicating data across different logical databases while controlling shared information. PostgreSQL 15 introduces native logical replication with column-level and row-level filtering within publications, allowing precise control over data transfer between PostgreSQL databases. Logical replication operates on a publish-subscribe model, where the source database logs changes to the Write-Ahead Log (WAL) and applies publication filters to transmit only the relevant data to the target database. Two filtering modes are available: column-level filtering allows users to specify which columns to replicate, while row-level filtering uses WHERE clauses to determine which rows to include. Both filtering modes can be combined in a single publication. The SQL syntax for creating publications and subscriptions is consistent across various PostgreSQL environments, with specific configurations required for enabling logical replication. Use cases for logical replication include multi-tenant SaaS data isolation, regional data distribution for ecommerce, PCI DSS compliance in financial services, development and testing environments, and retail inventory management. Prerequisites for implementing logical replication include using PostgreSQL 15 or later, ensuring network connectivity, having a user with replication privileges, enabling logical replication on the source instance, and monitoring WAL retention. Logical replication has limitations, such as the need for a replica identity for UPDATE and DELETE operations, the non-replication of DDL changes and sequences, and potential performance overhead during initial synchronization and ongoing replication. After testing, it is advisable to clean up by removing replication resources to prevent unnecessary costs.

Russia’s Digital Hydra Reaches Space With State-Backed MAX Messenger

Russia's state-backed messaging application, MAX, has facilitated over 1,000 messages between the International Space Station (ISS) and Earth. This was stated by Dmitry Bakanov, head of Roscosmos, during an event in Moscow. Cosmonaut Sergey Kud-Sverchkov is using MAX to communicate with the Roscosmos press office. The application allows developers to create their own sticker packs, with participation from celebrities and bloggers. MAX is promoted through mandatory pre-installation on devices sold in Russia, with some state functions requiring its use. Critics have described this rollout as coercive, viewing it as part of a strategy to promote domestic digital services. Russia recently launched 16 serial-production satellites for the Rassvet broadband system, marketed as an alternative to Starlink, although its current launch capabilities are limited.

Linux 7.0 Cuts PostgreSQL Performance in Half

An AWS engineer reported a significant drop in PostgreSQL throughput on Linux 7.0, with performance reduced to approximately half of its previous capability. Benchmark tests showed that the removal of the PREEMPT_NONE scheduling option was the main cause of this regression. On a 96-vCPU Graviton4 instance, throughput measured at just 0.51x compared to earlier kernel versions. Salvatore Dipietro from Amazon/AWS conducted benchmarking analysis of PostgreSQL 17, revealing that Linux 7.0 delivered only 0.51x the throughput of its predecessors. The root cause was traced to kernel commit 7dadeaa6e851, which eliminated PREEMPT_NONE as the default option, leading to increased contention due to the new PREEMPT_LAZY model. Profiling data indicated that 55% of CPU time is consumed by spinning in PostgreSQL’s spinlock, causing significant performance degradation. When a revert patch was applied, throughput rebounded to 1.94x the baseline. The decision to restrict preemption modes in Linux 7.0 aimed to address issues within the kernel's scheduling model. Dipietro proposed a patch to restore PREEMPT_NONE, but kernel developers suggested PostgreSQL adopt the rseq time slice extension instead. Database operators running PostgreSQL on Linux face potential performance reductions with the upgrade to Linux 7.0.
