Imaginary problems are the root of bad software

  • Imaginary problems can often be the root cause of bad software.
  • Miscommunications and long chains of communication can contribute to the creation of imaginary problems.
  • The persistence of imaginary problems can be driven by incentives to maintain job security and avoid fixing real problems.

Industry Reactions

  • The software industry's incentive system often prioritizes creating more solutions rather than focusing on what is actually needed, leading to bad software.
  • The industry's emphasis on features and innovation over stability and usability has resulted in complex and unnecessary designs, contributing to confusion among users.
  • Solving real problems for users and delivering stable, efficient, and usable software is important, and there is value in focusing on practical solutions rather than technical complexity.

A single line of code made a 24-core server slower than a laptop (2021)

  • The performance of a benchmarking tool called Latte was unexpectedly slower on a 24-core server compared to a laptop, despite having more cores available.
  • After investigation, it was discovered that the issue was caused by the use of shared reference counters (Arc) in the tool's code, which led to congestion and poor performance on the server.
  • The problem was addressed by implementing separate reference counters for each thread, resulting in improved scalability and linear performance scaling on the server.

Industry Reactions

  • The use of asynchronous code, coroutines, and parallelization techniques in programming.
  • The importance of dividing work in a way that maximizes parallelism and minimizes contention.
  • The impact of data structures and algorithms on parallel performance.
  • The challenges and trade-offs in scaling parallel programs.
  • The potential performance gains in optimizing code for parallel execution.

Goodbye, Twilio
