Principles

Some of the ideas I stand for. A collection of beliefs that guide how I live, code, build products, and work with others.

01

For Life

5 principles

  1. 01

    Be a prism, not a mirror. Seek to digest and break apart information, not just pass it on to someone else.

  2. 02

    Be conservative in what you do, be liberal in what you accept from others. (Robustness principle)

  3. 03

    Observe. Accept. Release. Transform.

  4. 04

    Sharing is growing and caring.

  5. 05

    Learning by doing. Teaching by example.

02

For Programming

12 principles

  1. 01

    Know your tools and build your own for repeated workflows.

  2. 02

    Done is better than perfect.

  3. 03

    Write code that's easy to replace, not easy to extend.

  4. 04

    Develop. Preview. Ship. Repeat.

  5. 05

    Premature optimization is the root of all evil.

  6. 06

    Read the Manual (RTFM).

  7. 07

    Documentation Driven Development (DDD).

  8. 08

    Open Source All The Things!

  9. 09

    Some programmers are 10× more efficient than others. I know because I've been both a 10× programmer and a -1× programmer.

  10. 10

    You may think that software development at a software company serves the customer directly, but you'd be mistaken. The organisation is the software development team's primary customer.

  11. 11

    The Web is my empathy medium.

  12. 12

    AI is an amplifier. It amplifies experience. It also amplifies confusion.

03

For Building Products

5 principles

  1. 01

    First, do not harm.

  2. 02

    Build. Measure. Learn.

  3. 03

    Experiments instead of Products.

  4. 04

    Fight the right fight.

  5. 05

    The code was never the bottleneck.

04

For Building Organizations

4 principles

  1. 01

    Individuals and interactions over processes and tools.

  2. 02

    Culture is what you document.

  3. 03

    Develop a culture where hard conversations are actively encouraged. Care deeply, but challenge directly.

  4. 04

    Collaboration requires leading by example. And by example I don't mean being someone with lots of ideas. I mean someone who actually enacts on their ideas and tries to get stuff done.

I don't know where I'm going, but I know who I'm going with.

I don't know where I am, but I know that I am in myself.

I don't know what God is, but God knows what I am.

I don't know what the world is, but I know it's mine.

I don't know what I'm worth, but I know not to compare myself.

I don't know what love is, but I know that I enjoy its existence.

I can't avoid the blows, but I know how to resist them.

I cannot deny violence, but I can deny cruelty.

I can't change the world, but I can change myself.

I don't know what I do, but I know that what I do does to me.

I don't know who I am, but I know that I am the one who doesn't know.
