Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.

How to Profile Modern PC Games with NVIDIA Nsight Graphics

Performance analysis in PC gaming has become more complex with the introduction of DirectX 12 and Vulkan, incorporating technologies like asynchronous compute, hardware ray tracing, and machine learning-assisted denoising. Understanding GPU performance requires advanced tools to analyze workload distribution and shader behavior, with NVIDIA Nsight Graphics being a key resource. NVIDIA Nsight Graphics is a graphics debugger and profiler for modern graphics APIs, featuring the GPU Trace Profiler, which provides detailed insights into GPU execution and performance bottlenecks. Recent updates have improved its utility, including a Flame Graph for the Shader Profiler and support for NVIDIA's DLSS in D3D12 applications. The Peak-Performance-Percentage analysis method focuses on identifying GPU workload constraints and optimizing utilization rather than relying on assumptions about performance bottlenecks. This methodology is applied using Nsight Graphics to analyze GPU traces from the game Cyberpunk 2077, contrasting traditional rasterization with path tracing enhanced by DLSS Ray Reconstruction. The test setup included an Intel Core i7-14700K CPU, 32 GB RAM, and an NVIDIA GeForce RTX 4090 GPU, capturing two scenarios: one with raster-only settings and another with path tracing and DLSS. The analysis revealed that the rasterized frame's most costly aspect was lighting processing, while the path-traced frame showed increased total frame cost and a hybrid workload involving rasterization, ray traversal, and AI-driven processes. Key findings indicated that modern GPU performance is heavily influenced by memory behavior rather than just shader arithmetic, with significant time spent on compute-driven lighting processing and data movement. The analysis also highlighted that ray tracing performance is constrained by memory efficiency, indicating that performance does not scale linearly with RT-core throughput.

Which messaging app takes the most limited approach to permissions on Android?

Messaging applications Messenger, Signal, and Telegram exhibit significant differences in permissions and operational behaviors that impact user privacy. Telegram has the fewest total permissions at 71, with 25 classified as dangerous; Signal requests 72 permissions, including 19 dangerous ones; and Messenger requests the most at 87, with 24 dangerous permissions. Messenger also has the highest number of vendor-specific unknown permissions. Access to sensitive resources is crucial for messaging functionalities, with permissions for contacts, camera, microphone, location, storage, and calendar being essential. Telegram and Messenger request additional system-level permissions, while Signal is more conservative and does not request certain permissions like phone-call control or overlay windows. The analysis, using the Mobile Security Framework (MobSF), indicates all three apps are in the medium risk category, with Messenger having more flagged issues. Telegram allows cleartext connections by default, potentially exposing traffic, while Signal uses encrypted connections by default and only permits limited cleartext traffic for certificate checks. Messenger's issues include world-writable files and remote debugging enabled in WebViews. Messenger uses third-party SDKs, while Signal and Telegram do not disclose third-party trackers. All three utilize Firebase Cloud Messaging for notifications without sensitive data leakage. Data exchange patterns show Messenger primarily routes traffic through North America, while Telegram and Signal focus on Europe with some additional connections in the U.S. and Asia.

Why Did Messaging App Telegram Fall From Grace in Russia

Russia plans to implement a full block on the messaging app Telegram on April 1, 2026, following increased pressure from authorities over six months, including halting calls, conducting regional shutdowns, and slowing functionality nationwide. Telegram has nearly 96 million users in Russia and serves as a media outlet and communication tool for various state agencies and military personnel. The app was initially embraced by the Russian government but faced conflicts leading to previous blocking attempts in 2017, which were largely unsuccessful. In 2020, Telegram was allowed to operate freely again, but the situation changed after Russia's invasion of Ukraine, with increased scrutiny following the launch of VK's messaging app, MAX. Recent developments suggest Telegram could be classified as an extremist organization, posing legal risks for its founder and users. Additionally, the Federal Antimonopoly Service claimed advertising on Telegram was illegal, complicating its market presence in Russia, where it hosts about 40 percent of the influencer market.

Russia thwarts protests over the blocking of a popular messaging app, but frustration persists

Authorities in nearly a dozen Russian regions have employed various justifications to cancel demonstrations against internet censorship and the blocking of Telegram, including citing "tree inspections," snow removal issues, and COVID-19 restrictions. Activists have largely refrained from unauthorized rallies due to increased crackdowns, opting instead for court challenges or smaller indoor gatherings. Telegram, with approximately 93.6 million users in Russia, is crucial for communication among government agencies and military bloggers, despite the government's push for a state-backed alternative. Protests against Telegram's restrictions have occurred, even among groups typically supportive of the Kremlin, with some activists being detained during attempts to demonstrate. Instances of small pickets have emerged, although many requests for rally permits are denied. Legal actions against the government regarding Telegram's restrictions have also begun, with a growing number of plaintiffs challenging the measures as violations of free speech and privacy rights.

МТС начал взимать ежедневную плату за использование VPN

MTS, a major mobile operator in Russia, has reclassified virtual private networks (VPNs) as equivalent to torrent services, imposing a daily fee of up to 87 rubles for users who wish to engage in private browsing. Traffic routed through VPNs will no longer be included in standard service packages, leading to additional charges for accessing blocked resources or securing connections. The new tariff structure charges users based on their region and plan, with fees ranging from 80 to 87 rubles per day for a quota of five gigabytes of specialized traffic. Users can block this service to avoid charges, resulting in the complete unavailability of VPN connections. This policy is seen as a response to pressures for new monetization strategies and aligns with government efforts to limit internet circumvention. The potential for other major telecom operators to adopt similar practices could impact net neutrality in Russia.
