Enable TCP port 2375 for external connection to Docker

See this issue.
Docker best practise to Control and configure Docker with systemd.

1. Create daemon.json file in /etc/docker:

    {"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}

Generate a private key and a CSR(Certificate Signing Request )

Use this method if you want to use HTTPS (HTTP over TLS) to secure your Apache HTTP or Nginx web server, and you want to use a Certificate Authority (CA) to issue the SSL certificate. The CSR that is generated can be sent to a CA to request the issuance of a CA-signed SSL certificate. If your CA supports SHA-2, add the -sha256 option to sign the CSR with SHA-2.

Creating a 2048-bit private key (domain.key) and a CSR (domain.csr) from scratch:

openssl req -newkey rsa:2048 -nodes -keyout domain.key -out domain.csr

Debugging Travis CI locally using Docker

This assumes you've got docker-machine installed, running, and can do docker run

1. Get a debug instance running

    docker exec -it travis-debug bash -l

This is a collection of books that I've researched, scanned the TOCs of, and am currently working through.  The books are selected based on quality of content, reviews, and reccommendations of various 'best of' lists.

The goal of this collection is to promote mastery of generally applicable programming concepts.

Most topics are covered with Python as the primary language due to its conciseness, which is ideal for learning & practicing new concepts with minimal syntactic boilerplate.

JavaScript & Kotlin are listed in the Tooling section; as they allow extension of VS Code and the IntelliJ suite of IDEs, which cover most development needs.

Installing gcc 4.8 and Linuxbrew on CentOS 6

The GCC distributed with CentOS 6 is 4.4.7, which is pretty outdated. I'd like to use gcc 4.8+. Also, when trying to install Linuxbrew you run into a dependency loop where Homebrew's gcc depends on zlib, which depends on gcc. Here's how I solved the problem.

Note: Requires sudo privileges.
