Good Principles
---------------
---

title: Join the fun
---
Good principles, or rules of thumb, are not so easy to formulate. They come from experience and abstract it.
If they don't come from, or not enough, experience they easily become just abstract and who really can tell
the difference (only one with more experience off course, and he/she does not need to read about principles).
A conundrum.
###Join the fun
- Microkernel
Or "leave it out if you can", is definately something i go by. A variation of make it as simple as you can,
but not more simple.
I am very open for people to join.
I just want to mention that this is my hobby, something i do in my spare time, for fun. I don't get any money and in fact,
running 2 companies, have to carve the time to do this.
As such i want it to stay fun. So i am looking for friendly, constructive, positive contact.
Please read the pages and the code and find something that interests you, possibly from the todo list.
Then talk to me what you are planning. Issues can be good to capture topic conversations, as there is no list.
Then fork and work on a branch before sending pull request.
I wrote some ideas in the about page, but here some more code related guidelines

wind is not just nice, it is essential. Software size is measured in tests passed, not lines written. Any
new feature is only accepted with enough tests, bugs fixed after a failed test is written.
- Layers represent an interface, not an implementation
It is said that every problem in computing can be solved by adding anohter layer of indirection. And so
we have many layers, which, when done right, help us to understand the system. (Read, layers are for us,
not the computer)
But implementing each layer comes with added cost, often unneccessary. Layers can and should be collapsed
in the implementation. Inlining, is a good example, a Jit another.
- Use names rightly
or the principle of least surprise. Programming is so much naming, so if done right will lead to a
natural understanding, even of code not read.
