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.

PostgreSQL vs SQL Server 2026: $0 vs $15K License

PostgreSQL has become the most utilized database for developers for two consecutive years as of 2026, while SQL Server has introduced native AI capabilities and vector search functionalities in its latest release. PostgreSQL is favored for new projects due to its permissive licensing, cross-platform operation, and extensive ecosystem of extensions, whereas SQL Server is preferred by organizations already using Microsoft products for its robust tooling and enterprise support. As of June 2026, SQL Server ranks third in the DB-Engines popularity ranking with a score of 698, while PostgreSQL ranks fourth with a score of 688. Developer adoption trends show that 49% of respondents in the Stack Overflow 2024 Developer Survey use PostgreSQL, compared to 27% for SQL Server. The latest stable version of PostgreSQL is 18.4, released on May 14, 2026, while SQL Server 2025 (version 17.x) became generally available on November 18, 2025. PostgreSQL is free under a permissive license, while SQL Server's Enterprise Edition can cost upwards of ,123 per two-core pack, with an eight-core minimum. PostgreSQL supports various operating systems, including Linux, Windows, macOS, and BSD, while SQL Server operates on Windows and Linux. PostgreSQL uses PL/pgSQL as its primary procedural language, allowing for multiple procedural languages, whereas SQL Server uses T-SQL. PostgreSQL's JSONB type offers rich indexing, while SQL Server added native JSON support in its 2025 release. Both databases are capable of handling high transaction volumes, but PostgreSQL excels in read-heavy scenarios due to its multi-version concurrency control, while SQL Server's columnstore indexes provide advantages for analytical workloads. PostgreSQL supports tables up to 32 TB, while SQL Server can handle a maximum database size of 524 PB. SQL Server's high availability technology includes Always On Availability Groups, while PostgreSQL offers built-in streaming and logical replication. The security features of both databases meet enterprise standards, with PostgreSQL providing a transparent patching process and SQL Server integrating with Microsoft tools. Real-world usage examples include Stack Overflow using SQL Server, while Instagram and Reddit utilize PostgreSQL. Developer sentiment increasingly favors PostgreSQL for new projects, emphasizing flexibility and open-source solutions. For new startups or greenfield projects, PostgreSQL is recommended due to its zero license cost and compatibility. Existing Microsoft enterprises are advised to stick with SQL Server for its integration benefits. Migration from SQL Server to PostgreSQL is becoming common, with a structured approach required for successful transitions.

Binance’s Android app privacy fight is back in the spotlight

Binance is facing scrutiny regarding the data collection practices of its Android app, which some users believe functions more as a data collection tool than a trading platform. Concerns have been raised about the app's extensive permissions and tracking capabilities, with a report indicating the presence of numerous tracking components, including SDKs from TikTok and WeChat, and over 50 system permissions. Binance's privacy portal states that data is collected for account management, security, marketing, fraud prevention, and legal compliance. Despite this, there are questions about whether the data collection practices are proportionate to the app's intended functions. Binance has a history of legal issues, including a guilty plea in November 2023 that resulted in a .32 billion penalty for anti-money laundering violations. The exchange claims to tailor its privacy framework to regional regulations, but user concerns about the app's tracking capabilities persist. As of early 2026, Binance has over 300 million registered users, making any privacy-related disputes potentially impactful. The ongoing scrutiny may lead to gradual adjustments in Binance's practices rather than a complete overhaul.

Google is pushing Android app building into a faster, more agentic era

Google is introducing a streamlined workflow for Android app development through its AI Studio, which integrates native app building and reduces the time from concept to launch. At the I/O 2026 event, Google highlighted that developers can now create functional Kotlin code using natural-language prompts, access a browser-based emulator, and conduct internal testing without extensive setup. The AI Studio can generate production-quality native Android code via Jetpack Compose, allowing for in-browser previews and easy project transitions to the Internal Test Track. This initiative aims to enhance the developer ecosystem, particularly benefiting startups by minimizing early experimentation costs and enabling faster iterations. Google is also addressing developer loyalty by providing effective tooling that encourages developers to stay within its ecosystem. The AI Studio connects with Google Workspace and offers a mobile app for project iteration, positioning itself as a gateway for broader software projects. This evolution in Android development emphasizes a shift away from traditional setups towards an AI-assisted workflow, influencing the speed and adaptability of startups.
