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.

Google must pay €4.1bn fine for using Android to ‘block’ rivals

Europe's highest court has ordered Google to pay a fine of €4.1 billion (£3.5 billion) for practices related to the Android operating system that stifled competition. The European Commission initially imposed a €4.3 billion fine in 2018, later adjusted to €4.1 billion in 2022, which the court upheld after Google's appeal. This is the largest fine ever levied against Google by the Commission. Google expressed disappointment with the ruling, stating it does not recognize their investments in Android. The original fine was based on allegations of three illegal practices, although it was noted that Android allows users to download alternative web browsers and use other search engines. Additionally, the European Commission previously fined Google €2.4 billion in September 2024 for abusing market dominance and €2.95 billion in September 2025 for breaching competition laws in online advertising. A Russian court also fined Google two undecillion roubles in October 2024 for restricting Russian state media channels on YouTube.

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.

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. The laptops were selected based on affordability, compatibility with Windows 11, and availability across multiple retailers.

From casual hobby to luxury investment: memory costs hit PC gaming hard

Two years ago, the gaming landscape was improving with affordable video games and devices like the Steam Deck making PC gaming more user-friendly. However, demand for AI data centers has disrupted manufacturing, causing component prices to rise significantly. Microsoft reported a 2.5 times increase in costs for memory and storage, leading to a 20% price hike for the Xbox Series S in the U.S. starting in August. Apple also announced a similar 20% increase on its hardware. The MSI Claw 8 EX AI+ has been launched at a price of ,499 in Australia, offering advanced gaming performance but at a steep cost. The Steam Deck remains a popular option at 9, while the ASUS ROG Ally provides alternatives for Windows users. The Nintendo Switch 2 offers a 1080p, 120Hz screen at a lower cost but lacks many major releases. Valve's Steam Machine was initially expected to start at 9, but due to the component crisis, it now starts at 9 for a 512GB model. DIY PC builds are becoming more accessible, with a recent build costing just over ,000. Consoles from Sony and Microsoft may offer better pricing for components despite recent increases. Cloud streaming services like Nvidia GeForce NOW and Xbox Game Pass are also emerging as cost-effective options.

Microsoft denies WSL 3 exists, reveals Windows 11’s WSL Containers ship next week

Microsoft has clarified that there is no WSL 3 in development, as stated by Craig Loewen, the Product Manager for the Windows Subsystem for Linux (WSL). The confusion arose from articles discussing a new feature called WSL Containers, which will be launched soon. WSL allows users to run Linux environments on Windows without dual-booting, while WSL Containers enable the creation and management of Linux containers directly within Windows, eliminating the need for third-party tools like Docker Desktop. WSL 1, introduced in 2016, served as a translation layer for Linux system calls, and WSL 2, launched in 2019, included a full Linux kernel in a lightweight virtual machine. WSL Containers is an enhancement to WSL, allowing developers to build, run, and deploy containers directly from Windows using the wslc.exe command. This feature is part of Microsoft's strategy to make Windows a more accessible platform for running Linux workloads, helping to retain developers who might consider switching to other operating systems.
