无用知识的有用性

弗莱克斯纳

[按] 30年代美国普林斯顿大学校长亚伯拉罕·弗莱克斯纳(Abraham Flexner)教授曾以 “无用知识的有用性”为题，发表过一篇在科学界有影响的文章。该文章强调了基础研究以及自由探索的重要性。全文一万余字，现节译如下，以餐读者。

Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

	// 3D Dom viewer, copy-paste this into your console to visualise the DOM as a stack of solid blocks.
	// You can also minify and save it as a bookmarklet (https://www.freecodecamp.org/news/what-are-bookmarklets/)
	(() => {
	const SHOW_SIDES = false; // color sides of DOM nodes?
	const COLOR_SURFACE = true; // color tops of DOM nodes?
	const COLOR_RANDOM = false; // randomise color?
	const COLOR_HUE = 190; // hue in HSL (https://hslpicker.com)
	const MAX_ROTATION = 180; // set to 360 to rotate all the way round
	const THICKNESS = 20; // thickness of layers
	const DISTANCE = 10000; // ¯\\_(ツ)_/¯

	# find and remove .DS_Store
	find . -name .DS_Store -print0 \| xargs -0 git rm -f --ignore-unmatch

	# create .gitignore file, if needed
	touch .gitignore
	echo .DS_Store > .gitignore

	# push changes to GitHub
