Amit's guide to math, algorithms, and code for hexagonal grids in games

Our design goals are safety, performance, and developer experience. In that order.

Contrary to popular belief, simplicity is also not the first attempt but the hardest revision

code, like steel, is less expensive to change while it's hot.

Safety

NASA's Power of Ten — Rules for Developing Safety Critical Code

• Use only very simple, explicit control flow for clarity.

• Put a limit on everything. Fail Fast

• Assertions detect programmer errors. The only correct way to handle corrupt code is to crash.

• Assertions are a safety net, not a substitute for human understanding.

  • Build a precise mental model of the code first.

  • encode your understanding in the form of assertions,

  • write the code and comments to explain and justify the mental model to your reviewer,

  • and use VOPR as the final line of defense, to find bugs in your and reviewer's understanding of code.

• No memory may be dynamically allocated (or freed and reallocated) after initialization.

• Declare variables at the smallest possible scope, and minimize the number of variables in scope.

• Good function shape is often the inverse of an hourglass: a few parameters, a simple return type, and a lot of meaty logic between the braces.

• Centralize control flow. When splitting a large function, try to keep all switch/if statements in the "parent" function, and move non-branchy logic fragments to helper functions.

• Centralize state manipulation. Let the parent function keep all relevant state in local variables, and use helpers to compute what needs to change, rather than applying the change directly.

Developer Experience

• Add units or qualifiers to variable names, and put the units or qualifiers last, sorted by descending significance. latency_ms_max rather than max_latency_ms.

• Callbacks go last in the list of parameters.

• Order matters for readability (even if it doesn't affect semantics). On the first read, a file is read top-down, so put important things near the top. The main function goes first.

• Don't overload names with multiple meanings that are context-dependent.

Testcontainers is an open source library for providing throwaway, lightweight instances of databases, message brokers, web browsers, or just about anything that can run in a Docker container.

The best components are those that provide powerful functionality yet have simple interface.

Do not add layers of abstractions for the sake of an architecture. Add them whenever you need an extension point that is justified for practical reasons.

Would you love me if I became a worm?, somebody could ask. I would respond that no, I don't in fact love you, for you are a worm.

Indeed I find humans more valuable.

This is a card game for teaching kids how to combine unix commands through pipes.

• make it for yourself first

• automate the backups; prefer to edit locally and push

• avoid SBCs (ie. RaspberryPi) and prefer PCs

• you don't have to let everyone in

I can't get the noise out of my head. People who watch the video express awe and disgust. And that is why Dutch software developer Bert Hubert's experiment is so powerful. It doesn't really uncover something that we shouldn't already know. Something we often choose to ignore. The brilliance is

Kind of controversial take on note taking systems. I can relate though, because i was lost in a burden of creating perfect knowledge management system for a long time without creating any knowledge. Simplest approach with commonplace notebook is what working for me now.
Comments are also useful.

Getting lost in your knowledge management system is a fantastic way to avoid creating things.
Most heart-stopping writing comes from synthesizing the previously unarticulated in the moment. Rather than reaching for your database, try channeling what’s in the air at this very second. These read/write errors are what we call originality.
Leonardo da Vinci kept all of his notes in one big book. If he liked something he put it down. This is known as a commonplace book, and it is about how detailed your note-taking system should be unless you plan on thinking more elaborately than Leonardo da Vinci.
Shun the useless adoption of the aesthetic of the useful. When something can be like work or like play, never make it work.

Personal goals are generally expected to happen later.
The reason it’s hard to get going on personal goals is that you’re already using all of your time. No matter who you are, you’re already using all 24 hours, every day, for something. Because this will always be true, goals that happen at all must happen now, while you still don’t yet have time.
Basically, you learn to work in small, uniform parcels of time. They’re short, timer-bound, and unwaveringly focused on a particular outcome. Most importantly, they can fit into real life, as it already is.

you can save stuff and it will auto label it. single page with all links, quotes, etc. smart search, tags
