Messenger Interoperability: Well-Intended, but Bad for Data Privacy

WhatsApp began supporting third-party messaging services in late 2025 in compliance with the EU's Digital Markets Act (DMA), which requires major tech companies to enable interoperability with alternative chat platforms. Threema has chosen not to implement interoperability with WhatsApp, citing concerns over user privacy and security, as differences in user identification methods could lead to compromises that weaken privacy protections. Threema believes that interoperability could reinforce WhatsApp's market dominance, reducing the incentive for users to adopt the Threema app. Additionally, Threema's business model relies on app sales for revenue, and a drop in downloads due to interoperability could threaten this model. Consequently, Threema has decided against pursuing interoperability with WhatsApp to maintain its commitment to privacy and security.

I Built My Second ETL Pipeline. This Time, I Started Thinking Like a Data Engineer

The author transitioned from a data analyst role to a data engineer, creating a 12-month self-study roadmap focused on learning by building projects. The first project was a GitHub ETL pipeline, which evolved from a simple Python script to a more complex system using SQLite and GitHub Actions for automation. The author realized that the challenges of data engineering lay in system design and orchestration rather than just writing ETL logic. For the second project, the author built an automated RSS ingestion pipeline to explore engineering decisions in creating a reliable data pipeline. The project emphasized the importance of separating application responsibilities from orchestration tasks, leading to the use of Docker for consistent execution environments and Kestra for orchestration. The author validated each component of the project incrementally: first the Python ETL, then PostgreSQL, followed by Docker, and finally Kestra. This approach ensured that each layer functioned correctly before adding complexity. The final architecture included distinct responsibilities for each component: Python for data processing, PostgreSQL for data storage, Docker for execution, and Kestra for orchestration. The author learned that effective engineering involves considering system reliability, error handling, and observability, shifting the focus from merely writing code to designing entire systems. The experience transformed the author's mindset, emphasizing the importance of incremental building and the separation of execution and orchestration responsibilities.

Microsoft is moving another Outlook feature behind a Copilot paywall

Microsoft will retire the Meeting Insight feature for Outlook users by early September 2026, after which users will lose access to meeting insights, relevant files, and emails. The company is introducing a new feature called "Prepare for this meeting" to summarize content for upcoming meetings. Previously, Meeting Insight did not require a Microsoft 365 Copilot license, but Microsoft is now requiring this license for Copilot Chat across applications like Word, Excel, PowerPoint, and OneNote. Microsoft has expanded its Copilot initiative to nearly 80 products and is shifting towards a paid model for features that were once complimentary.

From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley and was advised to focus on analytics rather than OLTP databases, which were considered solved. This led to the creation of Apache Spark and Databricks. However, during the development of Databricks, it was found that OLTP databases were not solved problems; they were difficult to scale and fragile. This realization led to the development of Lakebase, a serverless Postgres database designed with modern technology. Lakebase architecture separates the write-ahead log (WAL) and data files into independent, scalable services. The WAL is externalized to a service called SafeKeeper, which uses Paxos-based replication for durability, while data files are managed by PageServer, which stores them in cloud object storage. This design addresses challenges such as data loss, scaling, and performance interference between transactional and analytical workloads. Lakebase maintains compatibility with Postgres, offers unlimited storage, serverless compute, durable writes, and simpler high availability. It also introduces LTAP (Lake Transactional/Analytical Processing), which allows both transactional and analytical processing to operate on a single data copy in real time, eliminating the need for separate data copies and reducing costs. LTAP utilizes a unified storage layer that allows data to be materialized in both row and columnar formats, optimizing it for both transactional and analytical workloads. The system ensures that analytics can access the most current data without affecting transactional performance by using a log sequence number (LSN) to retrieve the latest changes. Unlike traditional CDC approaches, LTAP requires no explicit table replication, as all data is stored in a single governed copy. This architecture circumvents common issues faced by hybrid transactional/analytical processing (HTAP) systems, such as incomplete feature sets, lack of ecosystem support, and performance contention. The Lakebase architecture has unlocked capabilities like unlimited storage, elastic compute, durable writes, and instant branching, with ongoing developments anticipated in the future.

From monolith to Lakebase to LTAP: rethinking the database from storage up

Sixteen years ago, the author began their PhD at UC Berkeley, where they were advised to focus on analytics rather than OLTP databases, which were considered a solved problem. However, upon developing Databricks, they found that OLTP databases were cumbersome, challenging to scale, and fragile. This led to the creation of Lakebase, a serverless Postgres database designed to address these issues by externalizing the write-ahead log (WAL) and data files into independent services. Lakebase architecture separates the WAL into a distributed service called SafeKeeper and data files into another service called PageServer, allowing for improved durability, scalability, and performance. This architecture eliminates data loss risks associated with disk failures and misconfigurations, simplifies high availability, and allows for elastic compute resources. Lakebase also introduces LTAP (Lake Transactional/Analytical Processing), which enables transactions and analytics to operate on a single data copy in real-time, avoiding the need for separate data copies and reducing costs. The system retains Postgres's ACID semantics while storing data in open columnar formats, making it accessible to both transactional and analytical engines without the delays and complexities of traditional replication methods. The architecture allows for unlimited storage, serverless compute, and instant branching, while ensuring that analytics can read the most current transactional data without affecting transactional workloads. LTAP aims to unify transactional and analytical processing by leveraging distinct compute engines for each workload while integrating at the storage layer.

From Idea to Launch: Essential Steps for Building a Successful Android App

Building a successful app requires transforming a strong idea into a useful, reliable, and discoverable product. Key steps include addressing a genuine problem, developing an effective initial version, conducting thorough testing, and launching with a strategic plan. Many apps fail by neglecting essential steps, leading to confusion or lack of real need. It is important to identify specific problems the app aims to solve rather than starting with an extensive feature list. Understanding the target audience and their pain points is crucial for making informed decisions. Validation can be achieved by examining reviews of competing apps and engaging with potential users to assess interest in the solution. The initial app version should be the smallest iteration that delivers tangible results, focusing on the primary user journey. Outlining the user flow is important for a smooth experience, ensuring that permission requests are logical and intuitive. Early-stage apps should exhibit stability, integrating analytics and crash reporting from the beginning to understand user behavior. A gradual launch is recommended, starting with internal tests and moving to closed tests with target audience members. This phased approach allows for learning and adaptation, ensuring that the initial version effectively addresses a real problem and engages users.
