Another holy war?

This is the basic process to install and build an existing GRUNT project with npm on CentoOS 7.

Here’s a solution to fix issues like this …

$ bundle exec jekyll serve
Configuration file: /home/jtingiris/src/josephtingiris.github.io/_config.yml
            Source: /home/jtingiris/src/josephtingiris.github.io
       Destination: /home/jtingiris/src/josephtingiris.github.io/_site

1. Create a GiHub personal acces token with only the public_repo scope selectd. Here’s the GitHub Guide

2. Make sure to copy the token now. It wont be shown again. If you loose it then you’ll have to create a new one.

3. Export the token as an environment variable, e.g. via .bashrc. i.e.

   export JEKYLL_GITHUB_TOKEN=330103c2f8b25f4a3301b5be3e0f56371a133301
   

4. Verify the token is in your environment, i.e.

   echo $JEKYLL_GITHUB_TOKEN
   

5. Alternatively, you can use it inline, e.g.

   JEKYLL_GITHUB_TOKEN=330103c2f8b25f4a3301b5be3e0f56371a133301 bundle exec jekyll serve
   

All said and done, jekyll should serve without warning.

$ bundle exec jekyll serve

This is a highlight test.

Normal block

alert('Hello World!');

print 'helloworld'

Highlight block

alert( 'Hello, world!' );

print 'helloworld'

def foo
  puts 'foo'
end

def foo
  puts 'foo'
end

1
2
3

def foo
  puts 'foo'
end

#include <iostream>

using namespace std;

void foo(int arg1, int arg2)
{

}

int main()
{
  string str;
  foo(1, 2);
  cout << "Hello World" << endl;
  return 0;
}

At the time this was written, Asterisk 13 is the current LTS (long term support) version.

Ensure httpd is stopped and disabled.

This is an emoji test. lol.

By default, CentOS 7 KDE Plasma Advanced Desktop Effects wont allow a Compositing Type of OpenGL. This is a bug; Attempting to enable OpenGL 1.2, 2.0, or 3.1 on a VMWare (workstation) guest causes KDE to crash. The Desktop Effect settings continously revert back to a Compositing Type of XRender.

One of the rewards of switching my website to Jekyll is the ability to support MathJax, which means I can write LaTeX-like equations that get nicely displayed in a web browser, like this one \( \sqrt{\frac{n!}{k!(n-k)!}} \) or this one \( x^2 + y^2 = r^2 \).
