This is a post by Joel Spolsky. The original post is linked at the bottom.

This is such a common question here and elsewhere that I will attempt to write the world's most canonical answer to this question. Hopefully in the future when someone on answers.onstartups asks how to split up the ownership of their new company, you can simply point to this answer.

The most important principle: Fairness, and the perception of fairness, is much more valuable than owning a large stake. Almost everything that can go wrong in a startup will go wrong, and one of the biggest things that can go wrong is huge, angry, shouting matches between the founders as to who worked harder, who owns more, whose idea was it anyway, etc. That is why I would always rather split a new company 50-50 with a friend than insist on owning 60% because "it was my idea," or because "I was more experienced" or anything else. Why? Because if I split the company 60-40, the company is going to fail when we argue ourselves to death. And if you ju

Basics of Unix philosophy:

- Use simple algorithms as well as simple data structures
- Data structures, not algorithms are central to programming - organise it well
- Fancy algorithms are buggier than simple ones

Rules:

Modularity - build out simple parts connected by well defined interfaces. Be able to update/upgrade the part without breaking the whole.

@knapsack-pro/cypress supports environment variables provided by GitHub Actions to run your tests. You have to define a few things in .github/workflows/main.yaml config file.

• You need to set KNAPSACK_PRO_TEST_SUITE_TOKEN_CYPRESS environment variable in GitHub repository Settings -> Secrets. See creating and using secrets in GitHub Actions.
• You should create as many parallel jobs as you need with matrix.ci_node_total and matrix.ci_node_index properties. If your test suite is slow you should use more parallel jobs.

Below you can find config for GitHub Actions.
