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.

I thought Windows 11 broke GIFs, but the real reason was Google quietly pulling the plug on this service

Users of Windows 11 versions 24H2, 25H2, and 26H1 have reported an issue with the emoji panel where a message states that the "GIF service is not available" due to the discontinuation of the Tenor service on June 30, 2026. Microsoft confirmed that this issue occurs for users who have not installed the latest optional update that transitions from Tenor to GIPHY. To continue using GIFs in the emoji panel, users must install the latest Windows update; otherwise, they will encounter the error message. The transition to GIPHY was included in the June 23 preview update for the relevant versions.

Windows Defender ‘BlueHammer’ vulnerability now exploited as part of malware campaigns — CISA issues warning despite patch release on April 14

A race condition vulnerability in Windows Defender, known as BlueHammer, has been exploited by the hacker Nightmare Eclipse, allowing attackers to gain SYSTEM user access. Microsoft released a patch for this vulnerability on April 14, but the Cybersecurity and Infrastructure Security Agency (CISA) has flagged it as actively exploited in ransomware campaigns. The average time to apply critical OS patches across Windows 10 and 11 is now 127 days, with enterprise environments averaging 76 days. Estimates suggest that 15% to 26% of Windows 10 machines remain unpatched, with a conservative estimate of 20% translating to one in five machines being vulnerable. Microsoft has extended security updates for Windows 10 until October 14, 2027, but public awareness of the updates remains low.

Microsoft Shares Bounce From 52-Week Low as Italian Probe and Windows 10 Extension Create Crosscurre

The Italian antitrust authority, AGCM, has launched an investigation into Microsoft 365 for allegedly guiding users toward pricier subscription tiers by integrating AI tools like Copilot and Designer without explicit user consent. Microsoft has stated it will cooperate with the investigation. Last year, Australia’s consumer watchdog made a similar complaint regarding hidden costs related to Copilot during contract renewals. Despite this scrutiny, Microsoft shares rose to €327.90, a 5.71% increase, following a shift in investor sentiment towards AI-software firms. Microsoft also extended its Extended Security Updates (ESU) program for Windows 10 until October 2027, allowing users to delay transitioning to Windows 11, which could hinder hardware sales. The stock remains down nearly 19% year-to-date and is trading below key moving averages. The ongoing regulatory investigation and sluggish Windows upgrade cycle present challenges for Microsoft’s growth.

The Steam client was hurting PC gaming on Android — Valve’s VR headset accidentally solved it

Playing Windows games on Android has become feasible due to Winlator and open-source technologies like Wine, Box64, and DXVK. User-friendly applications such as GameHub and GameNative have emerged, enhancing mobile gaming experiences to rival dedicated handheld consoles. A major challenge was the reliance on the x86 Windows Steam client, which was resource-intensive on mobile devices. GameNative 1.0 introduced an experimental feature that eliminates the need for the desktop Steam client by using Valve's native Android libraries, improving the gaming experience significantly. Valve released Steamworks SDK version 1.63 in November 2025, which included native ARM64 libraries for Android, allowing for essential Steam functionalities without a translation layer. GameNative integrated these libraries, replacing the desktop client with a more efficient "bionic" Steam client that operates without a user interface, streamlining DRM and matchmaking processes. GameNative now supports Steam Guard TOTP sign-in, enabling smooth authentication and access to the user's Steam library. It downloads games natively, supports cloud saves, and is compatible with most single-player games with Steam DRM. The application boasts a high compatibility rate, with 221 out of 241 games in one user's library showing as compatible. GameNative 1.0 has improved performance with a Vulkan renderer and reworked controller stack. Despite its success, GameNative is not yet available on the Play Store, with nearly a million users sideloading the application. Developers aim to create a Play Store version that complies with Google's policies for easier installation.

Payday 2’s next update is “a massive undertaking” to modernize the FPS, stop crashes, and cut its install size by 60%

Starbreeze has transferred the ongoing support of Payday 2 to Sidetrack Games, allowing the original developers to focus on Payday 3. Payday 2 continues to attract around 30,000 players on Steam, while Payday 3 struggles with about 1,000 players. Sidetrack Games is planning a significant overhaul, migrating the game to a new 64-bit engine called Diesel 3.0, which aims to improve gameplay and reduce file size from 86 GB to 32 GB. An open beta for this upgrade is scheduled to start on June 30 and run until the end of July. The transition will require a complete re-download of the game, and some mods may break due to the engine change.

Windows RAT Uses Encrypted HTTP C2 and Registry Persistence After npm Infection

A malware campaign targets Windows systems through a malicious npm package named postcss-minify-selector-parser, which mimics the legitimate postcss-selector-parser. This counterfeit package installs a Remote Access Trojan (RAT) on developer machines, beginning with a multi-stage attack triggered by the installation of the package. The RAT can steal credentials, execute shell commands, and communicate with a remote attacker. Security researchers at JFrog identified this threat and reported it on June 22, 2026, noting that two additional related packages, postcss-minify-selector and aes-decode-runner-pro, are linked to the same publisher and remain live on the npm registry. The RAT employs encrypted HTTP communication with a command-and-control (C2) server and ensures persistence by creating a registry key under the Windows Run key. It has capabilities for remote shell execution, file uploads and downloads, and can steal saved login data from Google Chrome using Windows decryption APIs. The malware is designed for organized batch exfiltration of stolen data. Indicators of compromise include specific IP addresses, domains, file paths, and SHA-256 hashes associated with the malware components. JFrog advises users to remove the malicious packages, inspect their dependency trees, and treat any stored credentials as compromised.

I tested Microsoft PC Manager’s RAM-freeing tool and learned why high memory usage isn’t always a problem

Users of Windows 11 often report high RAM usage, with figures reaching 70-90 percent, leading to concerns about system performance and the need for memory upgrades. Microsoft has introduced the PC Manager application with a "Boost" option to help free up memory. High memory usage can be normal when Windows 11 caches files, but excessive consumption by poorly optimized applications may indicate a resource issue. The impact of memory usage varies by system; for example, 90 percent usage may be acceptable on a system with 96GB of RAM, while it could be problematic on an 8GB system. Context matters, as high memory usage on high-end machines often represents normal caching, whereas it may signal struggles on lower-end systems. The PC Manager's Boost feature can be useful before resource-intensive tasks but may reinforce misconceptions about high memory usage being inherently negative. Ultimately, performance issues, rather than memory percentage alone, should guide decisions about upgrading RAM.
