How we pushed CDC into Postgres, and turned replication into clockwork

Making data from transactional databases accessible to analytical databases is essential in modern data architecture, but it faces challenges such as fragile tooling, high costs, and complex operations. Snowflake has developed a Postgres service that addresses these issues by reimagining Postgres replication. Postgres is a strong operational database, but its change data capture (CDC) capabilities need improvement. Many data pipelines are fragile due to complexities in managing continuous data flow, schema changes, snapshots, and failures. To enhance user experience with Snowflake Postgres, a complete reinvention of the replication process was necessary. A new feature called data mirroring is in public preview, allowing resilient data replication into Snowflake with low cost, minimal lag, and transactional consistency. This feature directly pushes changes from Postgres into Apache Iceberg™ tables in transactional batches, which are then automatically applied to Snowflake tables without extra infrastructure. Change data capture records changes from a transactional database for replay on another system, primarily using logical decoding in Postgres. This method decodes WAL records into logical operations, but the client bears the responsibility for subsequent steps like backfilling, managing schema changes, and handling failures. Built-in logical replication in Postgres only addresses some complexities. A limitation of logical decoding is that the external system does not recognize the state of Postgres, making it difficult to detect schema changes or correlate snapshots with changes. The solution is to push changes from Postgres into a data lake, specifically into Iceberg tables using compressed Parquet format, with object stores like Amazon S3 as the destination. The mirroring process uses a new Postgres extension called snowflake_cdc, which continuously pushes batches of changes into per-table change logs and a meta log. This extension understands the Postgres environment, coordinating schema changes and complex transactions while ensuring alignment between snapshots and changes.

Sound Recorder, Camera, and Windows Studio Effects

Windows 11 includes a suite of audio and video recording applications: Sound Recorder, Camera, and Windows Studio Effects. The Sound Recorder app allows audio capture using PC microphones, featuring a navigation pane, recording area, and playback controls. Users can customize audio input in the Settings app under System > Sound, selecting microphones and adjusting quality formats like “CD quality” or “Studio quality.” Within the Sound Recorder app, users can change the recording format (default is AAC) to MP3, WMA, FLAC, or WAV and set audio quality to Best, High, or Medium. To record audio, users click the red “Start recording” button, with options to stop, pause, or mark significant moments using keyboard shortcuts. Recordings can be played back, managed, shared, renamed, or deleted through the app's interface. Users can also import compatible audio files into Sound Recorder. The Camera app allows users to take photos, record videos, and scan items using the PC's webcam, with an interface similar to smartphone camera apps. Users can customize camera settings in the Settings app under Bluetooth > Cameras, adjusting brightness, contrast, and resolution. Photos are taken in Photo mode, while videos are recorded in Video mode, with options for pausing without creating new files. Windows Studio Effects offers AI-driven enhancements for audio and video calls, requiring a Neural Processing Unit (NPU) for some features. Enhancements include automatic framing, background effects, creative filters, eye contact simulation, portrait lighting adjustments, and voice focus. Compatibility can be checked in Quick settings or the Settings app under Bluetooth & devices > Cameras. Each effect can be configured individually through the Settings app or supported applications.

Microsoft just decluttered Windows 11 Search after years of MSN tiles, ads, and trivia

Microsoft is rolling out significant enhancements to Windows Search, starting on July 13, aimed at creating a more streamlined and user-friendly experience for Insiders. The update eliminates clutter from the interface, removing web suggestions and ads, and replacing them with a clean home screen that displays recent searches. Each search result now includes clear labels indicating its source, and the layout has been improved for better organization. Sponsored product cards have been removed from web results, leading to direct answers without promotional content. Users can customize their experience with toggles to disable Bing web results or Microsoft Store suggestions. Local matches now take precedence over web results, improving search accuracy. File search has been enhanced to display results more quickly and include cloud files alongside local ones. Microsoft has also improved the reliability of Search, reducing crashes and loading issues. Users can enable the new features through the Feature flags page if they do not activate after a reboot. There is no official timeline for when these changes will be available to all Windows users.

Portal 2 just got a Steam Frame compatibility rating, hinting at the VR headset’s imminent launch

Valve is set to launch the Steam Frame this summer, with the classic game Portal 2 receiving a compatibility rating of Playable. The Playable rating is due to the lack of support for the Steam Frame's native resolution, meaning while the game runs smoothly, it won't utilize the headset's full resolution capabilities. The Steam Frame features a resolution of 2,160 × 2,160 for each eye, an upgrade from the Valve Index's 1,440 × 1,600 resolution. It also offers standalone gaming capabilities, unlike the Index, which required a PC connection. Valve's compatibility rating system includes Unsupported, Playable, and Verified categories. A late August release for the Steam Frame is anticipated, following the timeline of previous product launches.

As a longtime Android privacy nerd, here are 6 privacy apps I actually regret installing

The author shares experiences with six privacy applications that did not meet expectations. 1. Private Internet Access (PIA): A robust VPN service with a cluttered interface and concerns about its U.S. base; transitioned to NordVPN for a better user experience. 2. Brave Browser: Known for ad and tracker blocking, but had issues with Brave Search reliability, syncing, and battery drain; switched to Firefox with uBlock Origin. 3. LastPass: A former leading password manager that lost trust due to security breaches; moved to Bitwarden for its solid and secure platform. 4. KeePassDX: Impressive for local storage and clean UI, but lacked cloud syncing and required manual password management; eventually chose Bitwarden for convenience. 5. OpenBoard: A privacy-focused keyboard app that is no longer available on Google Play; basic features and installation hassles led to regret over its use; better alternatives exist. 6. OsmAnd: An open-source offline navigation app with extensive customization but a steep learning curve and rigid address searches; now prefers Organic Maps for ease of use.

Microsoft wants AI to customize your Windows 11 entirely with one sentence, shows off a demo

At Build 2026, Microsoft announced plans to enhance Windows 11 personalization through AI agents, with API endpoints available for developers to create tailored experiences. Product Manager Samantha Song highlighted the need for a more user-friendly interface that reflects individual preferences, noting current customization options can be cumbersome. Microsoft introduced "WinUI skills," enabling developers to use AI agents like Copilot to create native applications that interact with Windows APIs. Users could instruct AI to modify themes, such as creating a cherry blossom theme, which would adjust wallpapers and accent colors automatically. AI skills could also apply accent colors to File Explorer and download themed wallpapers. The theme module can orchestrate multiple actions, allowing users to change their entire Windows theme with a single command. Microsoft is exploring a themes agent for generating new themes. While currently an open-source project, there is potential for these features to be integrated into Windows 11, enhancing user experience through personalized customization.

Winlator is an application that enables Windows games to be played on Android devices by combining Wine with x86/x86_64 translation layers. The Snapdragon 8 Elite processor has compatibility issues, particularly with its Vulkan driver, making it less suitable for mobile gaming compared to the older Snapdragon 8 Gen 2. Users often resort to experimental drivers like Vortek to improve performance, but results can be inconsistent. The fragmentation of Winlator into various forks complicates the user experience, as each fork addresses different issues. GameHub, developed by GameSir, offers a more user-friendly experience but has faced criticism for invasive permissions. GameHub Lite is a modified version that improves performance and reduces tracking features. Ultimately, the Samsung Galaxy Z Fold 5 with the Snapdragon 8 Gen 2 provided a better gaming experience than the Snapdragon 8 Elite, benefiting from mature drivers and compatibility with GameHub Lite.
