Frequent failures and partial failures are inherent in distributed systems, requiring more robust design and the ability to take on increased costs. In distributed systems, careful coordination requires the help of data locality and partial availability.
Code "greppability" is when code is easy to search through thanks to easy-to-understand names. Dynamically constructing identifiers (e.g., table names and function names) makes code searching harder. Use flat, unnested structures for namespaces and components as it makes it easier to locate specific elements through simple searches.
Ken Kocienda saw Steve Jobs and Brian Chesky work up close and found that they had few key similarities. They both had deep intuition, a tireless work ethic, an unwavering commitment to their vision, and a fantastic ability to effectively guide and empower their teams. At the same time, they had differences such as Steve Jobs advocating for leaving smart people alone, while Chesky believed that founders needed to be more in contact with the “lower levels” of the company.
The "Project Hydra Effect” is when starting new projects feels more rewarding than finishing existing ones, leading to a cycle of endless beginnings and unfulfilled potential. Unfinished projects have an allure to them because there is comfort in their potential while also avoiding finality and criticism. However, not finishing projects leads to missed opportunities, mental clutter, and a lack of confidence.

Despite the Varnish cache project having over 150,000 lines of code, the average productivity of the two main developers of the project over ten years is estimated at only 5 lines per hour. This low productivity is a result of prioritizing quality and correctness over speed, as shown by extensive testing, meticulous code style, and a focus on avoiding errors. The lack of user complaints about Varnish suggests that this approach has successfully achieved its goal of producing high-quality software.
This article goes over a developer's journey in optimizing the boot time of a Raspberry Pi Zero 2 W for a solar-powered WiFi camera. The goal was to minimize energy consumption by reducing both the boot time and the power draw during boot. Various hardware and software techniques were explored, including disabling unnecessary components, adjusting kernel settings, and creating a custom Buildroot system with a stripped-down kernel. By implementing these optimizations, the boot time was reduced from over 12 seconds to less than 3.5 seconds, resulting in a fivefold reduction in energy consumption.
