What is Machine Learning
Tom Mitchell in 1998 provided a modern definition: “A computer
program is said to learn from experience E
with respect to some tasks T and some performance
measure P, if
its performance on T, as measured by P, improves
with experience E”.
Learn from Experience E in doing the task T measured by improvement in performance P
Example of playing
- E: the experience of playing many games of checkers
- T: the task of playing checkers
- P: the probability that the program will win the next game.
OKD is the acronym for OpenShift Kubernetes Distribution = Origin Community Distribution: (https://en.m.wikipedia.org/wiki/OpenShift)
OpenShift Origin in 2015 with the release of the OpenShift Version 3 was renamed to OKD.
NOTE: OpenShift version 4.2 is already out.
From the terminal on your local machine, run the ssh-keygen command, and follow the directions to save the file to the .ssh directory for your profile.
Note: the keys can be used for SSH connection to AWS, Git etc..
Generating public/private rsa key pair.
Enter file in which to save the key (/home/user-name/.ssh/id_rsa): Type /home/your-user-name/.ssh/ and a file name here, for example /home/your-user-name/.ssh/mykey_rsa
Enter passphrase (empty for no passphrase): <Type a passphrase, and then press Enter>
Enter same passphrase again: <Type the passphrase again, and then press Enter>
Your identification has been saved in /home/user-name/.ssh/mykey_rsa.
Your public key has been saved in /home/user-name/.ssh/mykey.pub.
The key fingerprint is:
The key's randomart image is:
+--[ RSA 2048]----+
| .o .=.=o.|
| . .. *. +|
| ..o . +..|
| So . . . |
| . |
- This generates:
mykey_rsa file, which is the private key file.
mykey_rsa.pub file, which is the public key file.
- Run the following command to display the value of the public key file (
Should looks similar to the following:
Snap Binding using jackson databind and templating using thymeleaf.
