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

Sixteen years ago, the author began their PhD at UC Berkeley and was advised to focus on analytics rather than OLTP databases, which were considered solved. This led to the creation of Apache Spark and Databricks. However, during the development of Databricks, it was found that OLTP databases were not solved problems; they were difficult to scale and fragile. This realization led to the development of Lakebase, a serverless Postgres database designed with modern technology. Lakebase architecture separates the write-ahead log (WAL) and data files into independent, scalable services. The WAL is externalized to a service called SafeKeeper, which uses Paxos-based replication for durability, while data files are managed by PageServer, which stores them in cloud object storage. This design addresses challenges such as data loss, scaling, and performance interference between transactional and analytical workloads. Lakebase maintains compatibility with Postgres, offers unlimited storage, serverless compute, durable writes, and simpler high availability. It also introduces LTAP (Lake Transactional/Analytical Processing), which allows both transactional and analytical processing to operate on a single data copy in real time, eliminating the need for separate data copies and reducing costs. LTAP utilizes a unified storage layer that allows data to be materialized in both row and columnar formats, optimizing it for both transactional and analytical workloads. The system ensures that analytics can access the most current data without affecting transactional performance by using a log sequence number (LSN) to retrieve the latest changes. Unlike traditional CDC approaches, LTAP requires no explicit table replication, as all data is stored in a single governed copy. This architecture circumvents common issues faced by hybrid transactional/analytical processing (HTAP) systems, such as incomplete feature sets, lack of ecosystem support, and performance contention. The Lakebase architecture has unlocked capabilities like unlimited storage, elastic compute, durable writes, and instant branching, with ongoing developments anticipated in the future.

Android’s Linux Terminal no longer restricts you to a single font and window in QPR1 Beta 6

The Android 17 QPR1 Beta 6 has introduced enhancements to the Linux Terminal app, including the ability to import custom fonts from phone storage and multi-window support. Users can now select their preferred font as the default and open new terminal windows via the three-dot overflow menu, with each window appearing in Android’s recents screen. The Linux Terminal app debuted on Pixel devices during the March 2025 Pixel Drop and has seen several improvements since its launch.

All Android users just got an important backup feature

Google is introducing a selective backup feature for Android users, allowing granular control over app data management. This update is initially rolling out to Pixel devices and users of Google Play Services version 26.24. Users can now selectively manage backups for each app, which helps conserve cloud storage space. The feature is available for those using Android 16 and Android 17, with other manufacturers expected to adopt it soon. Once activated, data is securely backed up to the cloud, but users should be aware that disabling backup for an app will permanently delete its previously backed-up data. To manage backups, users can go to their device’s settings under Google Services > Backup > Backup details. The rollout is gradual, primarily targeting Google Pixel smartphones. Most users will receive the update automatically, and they can check their version of Google Play Services in the settings.

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.

3 Old Windows Laptops Still Worth Buying In 2026

In 2026, the laptop purchasing landscape is affected by a price crisis due to AI data center demands, leading to higher costs for RAM, storage, and processors. Buyers are advised to consider laptops manufactured between 2019 and 2024 for compatibility with Windows 11, which requires a minimum of 4GB of RAM, with 8GB being the practical baseline and 16GB recommended for everyday tasks. 1. The Acer Swift X (2022) features an RTX 3050 Ti mobile chip, a Ryzen 5825U processor, and 16GB of LPDDR4X RAM, priced under ,000, and has a 4.4/5 rating on Amazon. 2. The Dell Latitude 7330 (2022) has a 1080p display, an Intel i5-1245U processor, and 16GB of RAM, available for around 0 from third-party sellers, and offers a convertible design. 3. The Acemagic LX15Pro is priced under 0, powered by a 5700U processor, has 16GB of RAM and a 512GB storage drive, and holds a 4.8/5 rating on Best Buy.

These Google Apps Need To Be Manually Updated On Your Samsung Phone

Google has rolled out updates for three system applications on Samsung Galaxy devices: Android System SafetyCore (version 0.925574157), Android System WebView (version 149.0.7827.91), and Google Play Services (version 26.22.33). These updates are not listed in the "Available updates" section of the Play Store and may require manual updating. Android System SafetyCore helps protect users from unwanted content, Android System WebView is essential for displaying web content in apps, and Google Play Services manages various functions like app updates and user privacy settings. To manually update these apps, users should go to Settings > Apps, select the app, and tap "App details in store" to access the Play Store. If other apps are not updating, users should ensure a stable internet connection, restart the phone, clear storage space, update the Android version, clear app caches, and check the system date.

Android finally lets you choose which apps are backed up, one by one

Google is rolling out an update that allows users to manage Android backups on a per-app basis, moving away from the previous all-or-nothing approach. Users can access this feature through Settings > Accounts & backup > Google backup, where they can see the three apps using the most storage and toggle backups for each app. Disabling the toggle stops future backups and deletes existing data for that app. The Device data section, including SMS messages and call history, remains unaffected. This feature is currently available on Pixel smartphones running Android versions 16 and 17 with version 26.24 of Google Play Services.

Former Microsoft engineer shrinks Notepad down to size

Dave Plummer, a former Microsoft engineer, has created TinyRetroPad, a minimalist text editor that is only 2.5 kilobytes in size. It aims to provide a simple text editing experience, reminiscent of older software like Notepad, which has become bloated over time with unnecessary features. TinyRetroPad includes essential functions such as Open and Save As dialogs, font selection, and printing capabilities, while using assembly language and the RICHEDIT50W from the WinAPI. The application requires more system resources to run effectively but focuses on maintaining lean code and binaries.
