docs: ✏️ update links and improve content across multiple documents

Revised various documents to enhance accuracy and clarity. Updated links in Blockchain.md, Coordination.md, Politics.md, Problem Solving.md, and Machine Learning.md to point to more relevant sources. Removed outdated references in Dungeons and Dragons.md and Remote Jobs.md, and improved the packing guide in Trip Planning.md. These changes ensure users have access to the most current information and resources.

   - Blockchains are "trustless". There are mechanisms in place by which all parties in the [[Systems|system]] can reach a consensus on what the canonical truth is.
   - Power and trust is distributed (or shared) among the network's stakeholders (e.g. developers, miners, and consumers), rather than concentrated in a single individual or entity (e.g. banks, governments, and financial institutions).

+1. Frame the problem. Define a clear and concise objective with clear metrics. [Write it as a design doc](https://applyingml.com/resources/ml-design-docs/).
 1. Get the data. Make the data tidy. Machine learning models are only as reliable as the data used to train them. [The data matters more than the model](https://twitter.com/beeonaposy/status/1353735905962577920). Data matters more than the model.
 1. Explore the data. Verify any assumptions. Garbage in, garbage out.
 1. Create a model. [Start with the simplest model!](https://developers.google.com/machine-learning/guides/rules-of-ml/). That will be the [baseline model](https://blog.insightdatascience.com/always-start-with-a-stupid-model-no-exceptions-3a22314b9aaa). Evaluate the model with the defined metric.
 1. Make sure everything works end to end. _You design it, you train it, you deploy it_. [Deploy the model quickly](https://nlathia.github.io/2019/08/Machine-learning-faster.html) and automatically. Add a clear description of the model. [Monitor model performance in production](https://youtu.be/hqxQO7MoQIE).
 1. Make results (models, analysis, graphs, ...) reproducible (code, environment and data). Version your code, data and configuration. Make feature dependencies explicit in the code. Separate code from configuration.
 1. Test every part of the system ([ML Test Score](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/aad9f93b86b7addfea4c419b9100c6cdd26cacea.pdf)): data (distributions, unexpected values, biases, ...).
-1. Iterate. Deliver value first, then iterate. Go back to the first point and change one thing at a time. Machine Learning progress is nonlinear. It's really hard to tell in advance what's hard and what's easy. [Engineering projects generally move forward, but machine learning projects can completely stall. It's possible, even common, for a week spent on modeling data to result in no improvement whatsoever](https://medium.com/@l2k/why-are-machine-learning-projects-so-hard-to-manage-8e9b9cf49641). Track every experiment you do. [Keep a reverse-time sorted doc where we you bullet points of what ideas you've tried and how they've gone](https://operatorai.substack.com/p/why-do-we-write-machine-learning). Look for data flywheel, harnessing the power of user's generated data to rapidly improve the whole system. These are powerful [[Feedback Loops]]. Attempt a portfolio of approaches.

 - Your perception of reality has probably been at least a little manipulated. Your opponents are behaving the way they are based on a perception of reality that's different from your own.
   - What does this look/feel like to the people I don't know?
 - Everyone belongs to a tribe and underestimates how influential that tribe is on their thinking. Tribes reduce the ability to challenge ideas or diversify your views because no one wants to lose support of the tribe. Tribes are as self-interested as people, encouraging [[ideas]] and narratives that promote their survival. But they're exponentially more influential than any single person. So tribes are very effective at promoting views that aren't analytical or rational, and people loyal to their tribes are very poor at realizing it.
