Implementing a fallback mechanism during system updates is crucial. If an update fails, it can prevent endless reboots by reverting to a stable version.
Keeping your Yocto project layers simple can reduce maintenance and complexity. Using minimal layers can help avoid outdated code and improve build efficiency.
Setting up a CI pipeline for Yocto builds can simplify the development process. It provides ready-to-use images for developers without requiring deep knowledge of Yocto.

CI/CD can contribute significantly to the cost of software infrastructure.
CI costs can increase at a quadratic rate over time due to various factors like team size and codebase growth.
Strategies to mitigate high CI costs include selective testing, maintaining code quality, and monitoring resources.

Poorly managed pull requests can harm developer productivity by creating bottlenecks.
Common issues in pull request management include lack of process, standardization, and visibility.
Toxic pull requests can be categorized into 11 types, such as outdated code, lacking documentation, and risky changes.

I/O-free tests are better for Test-Driven Development (TDD) because they are faster, isolated, and repeatable. This makes them more suitable for writing reliable software.
It doesn't really matter if tests are labeled as unit, integration, or acceptance tests. What matters is how easy they are to write and how quickly they run.
Successful software development practices like pair programming require a supportive company culture and a willingness from each developer to learn and adapt.

Quality is proportional to the quantity of feedback - more feedback means better quality.
Batching is inversely proportional to quality - more batching leads to lower quality.
Decreasing batching can be done through an Agile mindset, automated Continuous Integration/Deployment, feature toggling, early testing, breaking down large features, using MVP approach, and improving team communication.

Drone CI is a self-service Continuous Integration platform that simplifies CI pipeline configuration by using a .drone.yml file in the project's root directory.
Make sure the Drone service is public-facing with port 443 accessible, and use a read-through cache with Docker to ensure resilience to Docker Hub outages.
Add yourself as an administrator to new Drone installations to have full access to API features, set up cron interval as needed, and utilize the CLI tool for more advanced capabilities.

Data pipelines are transitioning towards a focus on reliability and efficiency, similar to software engineering practices.
Continuous Data Integration and Delivery in data engineering involves releasing data into production in response to code changes in a simple manner.
Observability and metadata gathering play a crucial role in ensuring data quality and preventing issues before they occur in data pipelines.
