Databricks has acquired Neon, a startup specializing in serverless Postgres, for one billion dollars. This acquisition aims to help businesses dismantle data silos and enhance AI capabilities. Currently, over 80 percent of databases on Neon's platform are generated by AI. Neon, founded in 2021, offers a fully managed serverless Postgres database and has been recognized as one of the top developer databases. The integration of Neon's technology with Databricks' platform is expected to improve efficiency for developers and enterprise teams, reduce performance bottlenecks, and lower costs. The acquisition is set to finalize later this year.
The Amazon Aurora PostgreSQL-Compatible Edition has integrated support for pgvector 0.8.0, enhancing vector search capabilities significantly. This version achieves up to 9x faster query processing and delivers 100x more relevant search results compared to previous iterations. Key improvements in pgvector 0.8.0 include:
- Up to 5.7x improvement in query performance for specific patterns.
- Introduction of the iterative_scan feature, enhancing recall for filter queries requiring approximate nearest neighbor (ANN) index searches.
- Improved cost estimation for more efficient query planning, allowing the selection of traditional indexes for complex filtered searches.
- Flexible performance tuning with two modes for iterative_scan: relaxed_order and strict_order.
Previous versions faced challenges with overfiltering, where combining vector similarity search with traditional SQL filters resulted in fewer results than expected. The HNSW indexing algorithm accelerates vector similarity searches by creating a multi-layered graph structure for efficient navigation.
Iterative index scans in pgvector 0.8.0 improve query reliability and performance by applying filters during the scanning process, reducing false negatives and enhancing performance. The configuration options for iterative scanning include off, strict_order, and relaxed_order, with relaxed_order providing the best balance between performance and accuracy.
In performance tests, pgvector 0.8.0 demonstrated substantial improvements across various query patterns, with significant enhancements in result completeness and recall. The database can now efficiently handle enterprise-scale applications, such as e-commerce and recommendation systems, with high performance and result quality even as product catalogs expand.
Best practices for deploying pgvector 0.8.0 include using HNSW with recommended parameters, creating additional indexes on commonly filtered metadata columns, and tuning query parameters based on specific use cases. Operational best practices involve using Graviton4-based instances for optimal performance, monitoring and tuning slow vector queries, and considering partitioning for very large tables.
App Actions on Windows have expanded to include Progressive Web Apps (PWAs) starting from Edge version 137. Developers can now publish their PWAs to the Microsoft Store, allowing for enhanced user interactions. App Actions enable users to access key features of an app directly from their current context, reducing distractions from switching between applications. For example, the note-taking app Goodnotes allows users to send text directly to the app without toggling windows. Developers can integrate App Actions into their Microsoft Store PWAs by defining an Action manifest, setting up a custom protocol handler, configuring the app as a share target, and packaging the app for the Microsoft Store using PWABuilder. Optionally, developers can define a PWA launch handler and test actions using the App Actions Testing Playground.
Microsoft is updating its Windows Notepad app with new text formatting options, including bold and italic styling, hyperlinks, lists, and Markdown support. This update is currently available to testers in the Canary and Dev Channels on Windows 11. A new formatting toolbar has been added at the top of the application, allowing easy access to these features. Users can toggle between formatted Markdown and Markdown syntax views. Notepad retains its plain text functionality, and users can clear formatting or disable the new features in the app settings. This update follows the introduction of an AI-powered Write function, enhancing Notepad's capabilities.
Microsoft has introduced text formatting capabilities in the Windows 11 Notepad application, allowing users to utilize Markdown-style input. This feature is part of the Windows 11 24H2 update for Insiders in the Release Preview Channel. Users can apply formatting options such as bold, italic, hyperlinks, lists, and headings, while also having the option to revert to plain text easily. The update is being rolled out to Windows Insiders in the Canary and Dev Channels with version 11.2504.50.0 of the app. This enhancement is part of a broader initiative to modernize Notepad, which has included features like multiple tabs, a built-in character counter, spell check, autocorrect, and AI-powered text summarization and generation. Users can disable new AI functionalities or uninstall the app to revert to the classic notepad.exe program.

The Vietnamese government has instructed telecommunications companies to block the Telegram messaging app, citing security concerns and the dissemination of "anti-state" content. This directive was issued by the Telecommunications Department and requires service providers to report compliance by June 2. A document from the Ministry of Public Security indicated that 68% of approximately 9,600 Telegram channels and groups in Vietnam were classified as “bad and toxic,” involved in activities such as anti-state messaging, fraud, and drug trafficking. The government referenced Article 9 of the Telecommunications Law and Decree 147 to justify the ban, claiming Telegram had not complied with regulations. Despite the ban, Telegram remained accessible in Vietnam as of the report date. Telegram expressed surprise at the government's actions and confirmed it is responding to legal requests from Vietnam.
Antivirus software is crucial for digital security, providing protection against malware threats. Users may need to disable antivirus temporarily for reasons such as system resource consumption, particularly during resource-intensive tasks like gaming, or to bypass false positives when installing applications. Disabling antivirus software poses risks, especially when browsing the internet, as even legitimate sites can be compromised. Precautions to take when disabling antivirus include disconnecting from the internet, avoiding USB drives, using trusted networks, closing non-essential applications, verifying the legitimacy of downloaded files, and limiting browsing to secure websites. Users should promptly re-enable their antivirus after completing necessary tasks.
Windows collects telemetry data, which includes hardware specifications, installed software, and system events, but does not reveal personally identifiable information. This data is encrypted and sent via HTTPS during significant events like system crashes. Users can manage optional data collection settings during initial setup or in the Privacy section of the Settings app, with enterprise versions offering more control. Mandatory data collection in Windows is more extensive than in macOS, while Linux has minimal data collection due to its decentralized structure. Users can disable some data collection, but some information will always be gathered unless advanced measures are taken.
