Using the Ruby on Rails logger block syntax can significantly improve performance by reducing unnecessary object allocations and CPU usage when logging messages. When strings are passed directly to logging methods like `Rails.logger.info`, objects are created regardless of whether the log level allows the message to be logged. This can lead to wasted resources, especially if the log level is set to ignore certain messages. By utilizing block syntax, the logger only evaluates the block if the log level permits it, thus preventing unnecessary object creation. For instance, when logging debug information while the log level is set to info, using a block results in fewer object allocations compared to passing a string directly. Although the performance gains may seem minor for small applications, they can become significant as the application scales. Adopting this practice can lead to better resource management and improved application performance over time.
- Using block syntax in Rails logging reduces unnecessary object allocations.
- Directly passing strings to logger methods can waste CPU resources.
- The log level can be adjusted dynamically in Rails to control logging output.
- Implementing block syntax is a small change that can yield performance benefits in larger applications.
- This practice enhances resource management as applications grow in traffic and complexity.

Structured logs are the way to start
Structured logs are crucial for system insight, aiding search and aggregation. Despite storage challenges, prioritizing indexing and retention strategies is key. Valuable lessons can be gleaned from email for software processes.
Optimizing JavaScript for Fun and for Profit
Optimizing JavaScript code for performance involves benchmarking, avoiding unnecessary work, string comparisons, and diverse object shapes. JavaScript engines optimize based on object shapes, impacting array/object methods and indirection. Creating objects with the same shape improves optimization, cautioning against slower functional programming methods. Costs of indirection like proxy objects and function calls affect performance. Code examples and benchmarks demonstrate optimization variances.
Plaintext is not a great format for (system) logs
Using plain text for system logs poses challenges due to rich metadata. Approaches include augmenting logs with metadata, storing it separately, or discarding it. Tools can help manage metadata, making logs more structured than plain text. JSON, though text-based, may not be plain text.
