FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

turbo

Merged from https://github.com/joelparkerhenderson/git_commit_message and https://chris.beams.io/posts/git-commit/

General Rules

• Commit messages must have a subject line and may have body copy. These must be separated by a blank line.
• The subject line must not exceed 50 characters
• The subject line should be capitalized and must not end in a period
• The subject line must be written in imperative mood (Fix, not Fixed / Fixes etc.)
• The body copy must be wrapped at 72 columns
• The body copy must only contain explanations as to what and why, never how. The latter belongs in documentation and implementation.

Finding and editing chunks with NBT Explorer

Download: https://github.com/jaquadro/NBTExplorer/releases

Alternatively NBT Studio is much faster and cleaner but works the same way https://github.com/tryashtar/nbt-studio/releases/

1. Figure out which chunk you are going for.

1.a If you are crashing due to an entitiy or tileentity the crashlog might contain the exact coordinates

1.b If you have a waypoint there for example checking your map files can be helpful

1.c If your player is in the same chunk you can look up your players position
