To understand what a daemon is,
I consulted The Linux Programming Interface and took notes related to it.

Basic Concept

Docker can be seen as a simplified virtual machine (VM).
Since it doesn’t install a full operating system, it offers a smaller footprint and faster speed.

Image

An Image contains a lightweight runtime environment,
including its libraries and executables.

Update

I’ve moved from Jekyll to Hugo.
This method is only applicable to Jekyll.

Sitemap

A sitemap is an .xml file that contains links to all the pages within a website.
With a sitemap,
a search engine can discover the pages and subsequently create indexes for them.
Then, people browsing the internet can find those pages using keywords.

Jekyll-sitemap

There is a plugin called jekyll-sitemap for Jekyll,
which automatically generates a sitemap whenever the website is rebuilt.

const with Normal Variables

Two ways to add const for normal variables:

const TYPE NAME = VALUE; // more common
TYPE const NAME = VAULE;

Both mean this variable cannot be assigned to another value.

For example,

Update

I’ve moved my blog from Jekyll to Hugo.
The method for adding a like button remains similar,
but the code and its placement need to be adjusted.

LikeCoin

I came across LikeCoin and it piqued my interest.
LikeCoin is a cryptocurrency,
which was created to encourage content creators.

Content creators can embed a Like Button within their content or web pages.
Anyone with a LikeCoin account who appreciates the content can click the button,
and the content creator will receive the corresponding LikeCoin.

The amount of LikeCoin a content creator receives depends on the account type of the likers.
The LikeCoin Foundation proportionally rewards free account likers,
while payment accounts are proportionally charged based on the number of likes they click each month.
More details can be found on LikeCoin’s Medium.

Every time a new folder is created and files are added in macOS, a .DS_Store file is generated within that folder. This results in numerous .DS_Store files scattered across macOS, and it’s quite annoying to add **/.DS_Store to every .gitignore file each time a new Git repository is created. Therefore, I found a method to prevent .DS_Store files from being tracked in all Git repositories.
