Modern app users don’t tolerate glitches — speed and stability are non-negotiable. Debugging across multiple Android devices, however, can be tedious if done manually. That’s why developers rely on Android Debug Bridge (ADB) to streamline development. With ADB, we can: In this guide, we’ll cover what ADB is, how it works, installation steps, and the most useful commands for debugging Android applications.

In less than 20 years, mobile apps have grown from a bright new idea to a cornerstone of our daily lives. And while Android accounts for the lion’s share of the market, iOS usage continues to grow exponentially: in 2024 alone, iOS apps and games were downloaded around 35 billion times. The Apple App Store is both a shop window and a marketplace for this global industry. But as iOS developers, how do we actually submit a mobile app to the store?

Data integration logging is the process of recording events and activities during data movement across systems, ensuring accuracy, troubleshooting, and regulatory compliance. In complex environments like those of Netflix and Airbnb, logging is critical for system reliability and performance. However, challenges such as managing large log volumes, inconsistent formats, and compliance requirements make effective logging difficult.

When your application suddenly fails at 3 AM, logs will be your best friend the next morning. But until this happens, we often treat logs as an afterthought. Sometimes there is a discussion on log levels or wording of the message, but we rarely go beyond that. After all, what's so interesting in pushing out a bunch of letters, perhaps with some additional metadata, which we will not use 95% of the time? The Elixir Logger module has us covered well. It's a solid foundation for our basic logging needs.

When managing Docker containers, effective logging is essential for troubleshooting, monitoring, and ensuring compliance. Mismanaged logs can lead to disk space issues, performance bottlenecks, and lost diagnostic data. Here's a quick breakdown of what you need to know: Choose the right logging driver: Options include json-file (default), syslog, journald, fluentd, and none. Each has unique benefits depending on storage, performance, and integration needs.
