A practical guide to cost optimization with Lakebase Postgres

Lakebase is a fully managed Postgres database designed for modern application development, featuring an architecture that separates storage and compute with a serverless compute layer. This design allows for cost efficiencies through various mechanisms: 1. **Branching**: Developers can create isolated environments for development, testing, or experimentation without duplicating storage costs, as branches share the same underlying storage. 2. **Autoscaling**: Lakebase adjusts compute resources based on activity levels, allowing users to pay only for the compute they use. It can scale down during low activity and can be suspended entirely after inactivity, reducing costs to zero. 3. **Read Replicas and High Availability**: The separation of storage and compute allows for adding read replicas and high availability without incurring additional storage costs, as these instances utilize the same storage layer. 4. **Synced Tables**: Integration with the Databricks Intelligence Platform enables efficient data syncing, allowing users to sync only the necessary working set of data, which helps avoid unnecessary storage and sync costs. 5. **Sync Modes**: There are three sync modes (Snapshot, Triggered, Continuous) for transferring data from the Lakehouse to Lakebase, each with different cost implications based on data freshness requirements. 6. **Right-sizing Compute**: Users can set the initial compute range during project provisioning to avoid over-provisioning and unnecessary costs. 7. **Monitoring and Metrics**: The Lakebase Metrics dashboard provides insights into working set size and cache utilization, helping users optimize their compute sizing and performance. 8. **Point-in-Time Restore (PITR) and Snapshots**: PITR maintains history for recovery within a configurable window, while snapshots offer discrete recovery points. Both are priced lower than standard storage, making them cost-effective options for data recovery. Lakebase costs are categorized into compute, storage, and serverless pipeline compute for syncing data. Compute is measured by CU usage, while storage includes branch storage, PITR history, and snapshot storage, all tracked separately. Users can access detailed usage and cost information through system billing tables.

DBtune autonomous optimization blows PostgreSQL bottlenecks away

DBtune, a startup based in Malmö/Lund, Sweden, was founded in 2020 by Dr. Luigi Nardi as a spin-off from Stanford University and Lund University. The company focuses on enhancing PostgreSQL's capabilities through autonomous database optimization technology and has raised .4 million in a seed round from various investors in July 2023, with support from the Wallenberg Foundation and Vinnova. DBtune's technology utilizes agentic AI for optimizing PostgreSQL databases by tuning server parameters, optimizing indexes, and monitoring autovacuum processes. The release of DBtune version 4.0 incorporates machine learning and AI to dynamically adjust server parameters and suggest optimal indexing strategies. The platform identifies and ranks potential index opportunities based on workload and provides recommendations for new indexes and maintenance of existing ones. A case study with Midwest Tape demonstrated a 10.8x performance improvement in database query runtime after employing DBtune for performance tuning. Benchmarking tests showed a transaction throughput increase of 87% during initial optimization, with a further 17% improvement on an already optimized system. Disk I/O activity was reduced by 43%, and WAL generation decreased by 23%. Dr. Nardi emphasizes the need for AI-driven optimization to manage the complexities of PostgreSQL databases and rising cloud costs, suggesting that significant code adaptations will be necessary for achieving fully autonomous PostgreSQL.

Microsoft confirms a Windows update can close games that use AC-3 audio

Microsoft has acknowledged an issue related to a Windows update (KB5124010) released on September 22, 2026, which has caused unexpected closures of various games that rely on AC-3 audio decoding. This issue affects Windows 11 versions 24H2, 25H2, and 26H2, while server editions remain unaffected. The problem primarily impacts legacy applications that depend on Windows' built-in audio decoding, particularly older PC games using the Dolby Digital codec for pre-rendered cutscenes and licensed soundtracks. Microsoft has confirmed the issue but has not provided a list of affected titles, workarounds, or a resolution timeline. The status remains unchanged as of October 7, and the issue persists regardless of user action.

Pixel 11 users are reporting Google Maps freezes and strange visual glitches in Android Auto

Users of Google's Pixel 11 series are experiencing significant issues with Google Maps while using Android Auto, including freezing, flickering, and graphical glitches. Reports describe "pixelated black static" appearing in place of the map, affecting both wired and wireless connections. Attempts to resolve the issue by uninstalling the app or clearing its cache have been ineffective. The root cause is unclear, and it is uncertain if Google is addressing the problem. Some users have found that keeping their device unlocked improves performance, while others report no issues. An earlier update to Google Play Services aimed to fix connection bugs, but feedback on its effectiveness has been mixed.

Lemuroid Setup Guide: 20 Retro Systems [2026]

Lemuroid is an open-source Android frontend built on top of the Libretro core ecosystem, maintained by developer Swordfish90. It is distributed under the GNU General Public License v3.0 and has 4,371 stars, 366 forks, and 595 open issues on GitHub. Late 2026 is a good time to set it up due to its active development. It is available on Google Play, F-Droid, and GitHub, providing redundancy in case of policy changes. Lemuroid supports twenty systems, each mapped to a specific Libretro core. PlayStation 2, GameCube, and Nintendo Switch are not supported. It requires Android 6.0, 500MB of storage, 3GB of RAM for 8-bit and 16-bit systems, and legally dumped ROMs/ISOs. BIOS files are required for PS1, PSP, and DS cores. It is recommended for managing multiple systems in one library.

Google Admits Some ‘Complex’ Android Apps Run Poorly On Intel Googlebooks

Googlebooks, designed for Android smartphones, is facing compatibility issues with certain complex Android applications on Intel x86 versions. Google stated that most apps run well on both Intel and Qualcomm versions, but some complex apps need developer adjustments due to their original design for ARM chips. Google is collaborating with app developers and chip manufacturers to improve performance and compatibility. They have created a selection of optimized apps for Googlebooks, but users can still download apps from the Play Store without these optimizations. Compatibility issues have not been specified, and Intel Googlebooks use a hardware translation layer for ARM apps, which may affect performance and battery life. Currently, there are three Intel Core 5 Googlebooks from Acer, ASUS, and Lenovo, and two ARM models from Dell and HP. Further testing will provide more information on app compatibility across these platforms.

Microsoft confirms Windows 11 26H2 is crashing some games and apps, promises to fix it in the next update

In October 2026, Microsoft is addressing ongoing issues from its September updates for Windows 11, particularly related to audio decoding. Certain applications and games using Windows' built-in AC-3 (Dolby Digital) audio decoding may crash when users adjust volume or audio settings. This issue primarily affects older applications and games, while most modern apps are expected to function normally. Microsoft has issued multiple updates, including a mandatory Patch Tuesday update and an emergency patch, but some audio problems remain unresolved. The September updates also introduced a significant increase in security fixes, addressing 974 vulnerabilities compared to 86 in September 2025. Additionally, an emergency update disrupted the functionality of File History, which Microsoft is investigating. An optional update aimed to fix File History but led to new crashes in various applications. Microsoft is currently working on a resolution for the audio-decoding bug without a specified timeline.
