My Learning Plan for Getting Into Data Science from Scratch

Image
My decision to get into data science started way back when I was still in college in early 2015. I actually didn’t plan to become a data scientist originally, but a  quant  — someone who is essentially a financial analyst that uses advanced math and coding in their functions (e.g. risk management and algorithmic trading); however, a 9-month quant internship made me realize that I wanted to apply these skills to a wider context. A few blog post readings later, I concluded that data science was the field for me. Coming from a background in Applied Economics, I felt my econometrics heavy curriculum already gave me a decent foundation for the math; however, I still had no background in the models used in machine learning (e.g. neural networks, random forests). In addition, I looked through the courses for the rest of my stay in university and found nothing that taught us how to code our own algorithms. The gap was clearly my lack of knowledge in 1) coding and 2) machine learning mode

DevOps Series: Running Oracle Database 19C in a Docker Container

Introduction In this article, we will learn the prerequisites to install Docker follows with Docker installation and then using Docker container we will see how to run the database on it along with the listener. In our environment, we have used Linux 7.5 and Docker version as 1.23.1. We just need a very lightweight Linux machine to use the Docker. First, we are going to install the Docker engine and Docker compose. i) Install Docker Engine: sudo yum install docker-engine -y Before installing Docker Engine, ensure to make changes in your public-yum-ol7.repo file as mentioned by, A Simple Guide to docker installation on Oracle Linux 7.5,  Puneeth Prakash  (  https://blogs.oracle.com/blogbypuneeth/a-simple-guide-to-docker-installation-on-oracle-linux-75 ) ii) Start Docker: sudo service docker start #  docker — version Docker version 18.09.1-ol, build c3ab8a8 iii) Install Docker-compose: Docker Compose  is a tool that allows you to define and run multi-container Docke

Below are the steps to install docker using Oracle YUM repository: Step 1 . Set your proxy : Command :  export http_proxy=xxx.xxx.xxx.xxx:80 Command :  export https_proxy=xxx.xxx.xxx.xxx:80 Step 2 . Take a backup of existing public-yum-ol7.repo : Command :  cd /etc/yum.repos.d/ Optional Command :  mv /etc/yum.repos.d/public-yum-ol7.repo /etc/yum.repos.d/public-yum-ol7.repo_org1 Step 3 . Download the latest public-yum-ol7.repo from Oracle YUM repository: Command :  wget http://yum.oracle.com/public-yum-ol7.repo Step 4 . Make the following changes in your public-yum-ol7.repo file: Command :  vi public-yum-ol7.repo [ol7_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=https://yum.oracle.com/repo/OracleLinux/OL7/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1 [ol7_UEKR4] name=Latest Unbreakable Enterprise Kernel Release 4 for Oracle Linux $releasever ($basearch) baseurl=https://yum.oracle.com/repo/Ora
