Secure Boot certificate updates are broken on some PCs, Microsoft confirms

Microsoft has acknowledged that several older Secure Boot certificates have expired, necessitating updates for Windows 10 and 11 users. A temporary halt in the issuance of new Secure Boot certificates affects specific PCs, particularly various HP models. Most PCs will receive updates automatically through Windows Update, but some may require a firmware update from the manufacturer. Users may see messages indicating that Secure Boot certificate updates are paused or blocked due to known issues or hardware/firmware limitations. Until manufacturers like HP release necessary firmware updates, users cannot update their Secure Boot certificates. Although the immediate risk from expired certificates is low, it is expected to increase over time. Devices with un-updated Secure Boot certificates will continue to function normally, but they will not receive new security updates, making them vulnerable to emerging threats. Essential features that rely on updated security measures may cease to function correctly as new security challenges arise.

What Is Serverless PostgreSQL?

Serverless PostgreSQL is a fully managed cloud database model that separates compute and storage, allowing them to scale independently and automatically based on demand. It eliminates the need for manual infrastructure provisioning and capacity planning, charging only for active usage. Unlike traditional PostgreSQL setups, which require continuous resource allocation and manual scaling, serverless PostgreSQL provisions resources on demand and can scale down to zero during idle periods. Serverless PostgreSQL integrates with serverless compute platforms, enabling analytical queries to access the same data within a unified architecture. Key differences between traditional and serverless PostgreSQL include manual versus automatic provisioning and scaling, fixed versus usage-based billing, and high versus reduced operational overhead. Lakebase architecture is an emerging model that combines transactional databases with lakehouse foundations, allowing operational and analytical workloads to coexist on a single platform. This architecture minimizes data duplication and simplifies access, enhancing data management and analysis. Serverless PostgreSQL operates on a cloud-native architecture that enhances efficiency by allowing compute and storage to scale autonomously. It features scale-to-zero behavior, where compute resources are suspended when inactive and reactivated upon new queries. Major providers include Databricks Lakebase, Amazon Aurora Serverless v2, and Neon, each offering varying capabilities and integrations. Pricing for serverless PostgreSQL typically includes charges for compute resources, storage, and data transfer, with costs fluctuating based on workload activity. Cold start latency is a performance consideration, as reactivating compute resources can introduce delays. Strategies to mitigate this include keeping resources partially active or selecting providers with minimal cold start impacts. Serverless PostgreSQL is well-suited for OLTP workloads, while lakebase architecture is better for AI development, variable workloads, and environments requiring rapid iteration. Setting up serverless PostgreSQL involves choosing a provider, creating a database instance, and configuring access settings. It can also be used alongside serverless compute platforms for analytics, further extending its capabilities.

Microsoft’s new Windows 11 recovery tool is the ultimate Undo button

On July 19, 2024, at 12:09 AM EDT, 8.5 million Windows PCs, including devices from half of the Fortune 500 companies and the leading U.S. cybersecurity agency, experienced a catastrophic failure due to the Blue Screen of Death, leading to reboot loops. IT teams had to physically access each machine to resolve the issue by removing a problematic CrowdStrike file. CrowdStrike released an automated remediation tool three days later, on July 22. Microsoft pledged to improve Windows' resilience, introducing Quick Machine Recovery nearly a year later. Microsoft unveiled a new recovery feature called Point-in-time Restore, which allows users to revert their PCs to a previous state when functioning correctly. This feature generates daily snapshots of the entire system using the Volume Shadow Copy Service, retaining the three most recent snapshots and consuming minimal disk space (typically 2% of the system drive). Users can access the restore point through the Windows Recovery Environment after three failed startups, with the restoration process taking 30 to 45 minutes. Point-in-time Restore differs from System Restore, which creates less comprehensive snapshots and preserves document files. Point-in-time Restore is automatically enabled for systems with at least 200 GB drives in retail or OEM editions of Windows Home or Pro, while it must be manually activated for smaller drives. In Windows 11 Enterprise edition, it is disabled by default and may require administrative approval to activate. The feature intelligently manages disk usage, discarding older snapshots as needed, but users must enter a BitLocker recovery key if their system drive is encrypted. Users are warned about the risk of losing unsaved work when applying a restore snapshot, and reversing the operation is not straightforward.

Telegram’s ad business: How the messaging app makes money

Telegram has established an advertising model that focuses on monetizing public channels, selling ads based on channel topics rather than user identity. Revenue generated from ads is split evenly between Telegram and the channel owner, with no data-mining or behavioral targeting involved. The primary ad format is Sponsored Messages, which appear in public channels with at least 1,000 subscribers and consist of a text block and optional call-to-action button. Advertisers can purchase these ads through a self-serve portal without demographic targeting, ensuring no personal data is used for placements. Public channels are treated as independent units, with 50% of ad revenue going to channel owners, paid in Toncoin. Telegram's ad system has become more accessible by lowering minimum spend requirements. In addition to Sponsored Messages, Telegram is developing Mini Apps funded by its in-app currency, Stars. Regulatory scrutiny has increased, with various countries imposing bans or restrictions on Telegram for reasons related to content moderation and compliance, such as a temporary ban in India in June 2026 due to exam fraud investigations.

The database that refused to die: How Postgres survived its own creators

Postgres, originally developed by Michael Stonebraker in the early 1980s, is an open-source database system that evolved from Ingres. It was designed to handle complex data types and introduced user-defined data types, operators, and functions, leading to the support for abstract data types (ADTs). The initial commercialization of Postgres occurred through a startup named Illustra, later acquired by Informix. In 1995, graduate students Andrew Yu and Jolly Chen revived Postgres, transitioning it from QUEL to SQL, resulting in Postgre95, which evolved into PostgreSQL. Today, Postgres is one of the most popular database systems globally, known for its extensibility and high code quality. However, it currently lacks features like file-level encryption (TDE), which are standard in commercial systems, relying instead on the operating system for encryption. Efforts to implement TDE have faced challenges due to the complexity of required code changes.
