Discover gists

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Filling an array or slice with a repeated pattern

Looking for an efficient pure GO approach to copy repeating patterns into a slice, for a toy project, I ran a few tests and discovered a neat approach to significantly improve performance. For the toy project, I am using this to fill a background buffer with a specific RGB color pattern, so improving this performance significantly improved my acheivable framerate.

All the test were run with a buffer of 73437 bytes, allocated as follows

var bigSlice = make([]byte, 73437, 73437)

Fill the slice with the value 65 by looping through each element and setting the value

How to push tagged Docker releases to Google Artifact Registry with a GitHub Action

Here's how I configured a GitHub Action so that a new version issued by GitHub's release interface will build a Dockerfile, tag it with the version number and upload it to Google Artifact Registry.

Before you attempt the steps below, you need the following:

A GitHub repository that contains a working Dockerfile
The Google Cloud SDK tool gcloud installed and authenticated

	// Spec http://www.ecma-international.org/ecma-262/6.0/#sec-json.stringify
	const replacer = (key, value) =>
	value instanceof Object && !(value instanceof Array) ?
	Object.keys(value)
	.sort()
	.reduce((sorted, key) => {
	sorted[key] = value[key];
	return sorted
	}, {}) :
	value;

	Model::

	/Select/
	select('col1','col2')
	->select(array('col1','col2'))
	->select(DB::raw('businesses.*, COUNT(reviews.id) as no_of_ratings, IFNULL(sum(reviews.score),0) as rating'))
	->addSelect('col3','col4')
	->distinct() // distinct select

	/From/
