Why High-Performance Android Apps Require More Than Just Kotlin and Jetpack

Smartphone users expect immediate feedback and seamless experiences from applications, which requires a holistic approach to mobile development that integrates user interface design with robust server-side capabilities. Challenges in app architecture and backend integration can hinder performance, particularly for high-level applications. Developers often focus on frontend aspects, neglecting the importance of backend processes, which can lead to issues such as inefficient API payloads and data fetching latency. Architectural bottlenecks, like excessive data retrieval, can waste bandwidth and battery life. A well-structured Android architecture can separate UI from data management complexities, aiding scalability. Modern tools like Jetpack Compose enhance UI development but can introduce performance issues if backend state delivery is inconsistent. Collaborating with specialized nearshore mobile app development teams can help US-based companies address these challenges effectively, benefiting from time zone alignment and cost-effective solutions while maintaining engineering expertise.

OpenAI Scales ChatGPT to 1M Queries/Second with PostgreSQL on Azure

OpenAI has optimized its database infrastructure using PostgreSQL to support 800 million monthly active users and process over a million queries per second without complex sharding. The architecture consists of a single primary instance with nearly 50 read replicas, achieving low double-digit millisecond response times at the 99th percentile. OpenAI employs best practices like connection pooling, query optimization, and strategic indexing, utilizing tools such as PgBouncer for efficient connection management. The company has achieved five-nines availability through failover mechanisms and has adapted to a tenfold increase in query volume within a year by tuning PostgreSQL parameters rather than creating custom solutions. OpenAI incorporates community-driven optimizations, such as custom indexing strategies and materialized views, and uses extensions like pgvector for managing vector data and embeddings. The organization continuously monitors for strain during traffic surges and adjusts by adding replicas or optimizing configurations. Their approach emphasizes simplicity, avoiding sharding to minimize operational overhead, and they plan to explore newer PostgreSQL features and AI-native capabilities in the future.

How to delete your OpenAI account in the Android app: Step-by-step guide to permanently remove data, manage subscriptions, and protect your privacy | – The Times of India

OpenAI accounts provide access to the ChatGPT API and related services. Users can delete their accounts through the ChatGPT Android App, but this action is irreversible, meaning all data will be permanently removed and the email address cannot be reused for new accounts. Account deletion ensures the removal of personal information, chat logs, and API usage records, although some data may be retained for legal reasons. The deletion process involves several steps: accessing the app menu, navigating to settings, going to data controls, and confirming the deletion. Users must cancel any active subscriptions separately, as account deletion does not automatically terminate them. After deletion, users will lose access to all OpenAI services, and their account information will be erased within 30 days, except for legally required data retention. Best practices before deletion include backing up important data, canceling subscriptions, and reviewing linked services.

Why AI Workloads Are Fueling a Move Back to Postgres

The database landscape has seen transformative shifts with the rise and fall of various technologies, leading to a resurgence in the adoption of PostgreSQL (Postgres) as a favored database system for modern AI applications. AI workloads have disrupted traditional managed database models, which were designed for predictable workloads, by introducing demands for high parallelism and continuous ingestion of large datasets. Engineering teams face challenges when scaling managed Postgres instances due to IOPS limits, throttling, and latency spikes. Major database vendors are emphasizing PostgreSQL compatibility, recognizing the need for a stable SQL system with strong transactional support. Despite its advantages, traditional managed database models present limitations, including reliance on network storage that introduces latency and IOPS constraints. A new model called Bring Your Own Cloud (BYOC) Postgres is emerging, allowing organizations to control their cloud environments while leveraging managed services, improving performance by colocating data with compute resources. Utilizing local NVMe storage with Postgres can enhance performance by reducing latency and IOPS limitations. Modern Postgres platforms facilitate efficient cloning processes that support parallel experiments in AI development, leading to shorter feedback loops and faster iteration cycles. The robust ecosystem of Postgres allows it to handle diverse workloads, streamlining data management and minimizing operational complexity. Developer velocity is a critical factor in the shift back to Postgres, as it enables rapid feedback and safe testing environments, empowering teams to innovate more effectively.

Vietnam’s dominant messaging app faces regulatory scrutiny over data policy update

Vietnam’s National Competition Commission (NCC) has ordered VNG Corporation to revise its updated service terms for the Zalo messaging app due to user privacy concerns. The NCC emphasized that users should not be forced to consent to personal data collection as a condition for using the app and that consent mechanisms need to be voluntary and clear. The updated terms require users to accept all data management provisions or face account deletion within 45 days, which has led to significant user complaints and a decline in app ratings. Zalo's average rating on Apple’s App Store has fallen to around two out of five stars, and it has slipped to 59th place in download rankings, while international apps like WhatsApp and Viber have become more popular. Zalo has around 78 million active users and operates over 17,000 official accounts used by government and businesses. The NCC intends to meet with VNG to discuss the updated policy, as part of a wider regulatory trend against coercive data practices in digital firms globally.

SSDs on some Windows machines with BitLocker enabled are about twice as fast thanks to BitLocker hardware acceleration.

Windows 11 Pro has introduced a hardware-accelerated version of BitLocker, enhancing storage encryption without compromising performance. This update allows compatible devices to maintain storage read and write speeds similar to when BitLocker is disabled. The hardware-accelerated BitLocker utilizes the encryption processor in the System on Chip (SoC) to streamline encryption and decryption processes. It is available on devices with a supported built-in encryption processor and uses the XTS-AES-256 encryption algorithm. Users can check if hardware BitLocker is enabled by executing the command manage-bde -status in the command prompt. Performance metrics indicate that CPU cycles during storage access remain consistent with machines that have BitLocker disabled, and benchmarks show that hardware BitLocker can double sequential read and random write speeds. The integration of the XTS-AES-256 encryption processor into Intel's upcoming third-generation Core Ultra processor, Panther Lake, suggests future advancements for hardware-accelerated BitLocker.

Here’s the latest on Google’s work to enhance Android backups

Google is refining its backup functionalities for Android users, focusing on the downloads folder and per-app backup settings. Users will soon be able to back up files from their downloads folder, but edits made to these files will not sync with the backup on Google Drive. Additionally, a new notification will inform users that disabling backups for a specific app will result in the deletion of its backup copy. The interface for managing app backups is also being updated to differentiate between user applications and system processes. These features are currently in beta and not yet publicly available.
