• How to write markdown (.md) files.

Java/Kotlin Bootcamp:

The course started by:

1. Jobs and Organizational Tasks

2. Agile Development ++ (Software Project Management)

3. Logic and Computational Thinking

   1. Requirements:
      • Functional: It is funtionalities
      • Non-funtional : Funtionalities properties/How it works
   2. Which resources I do have (and is obtainable)
   3. What are the problems?
   4. Which requirements changing, or incertainty, might break your projects?
   5. Break your problem into a tree by reducing the problem in easier tasks
   6. For each task look for:
      • Patterns
      • Abstractions
      • Process
      • Math model
      • Data Struct
      • Big O techs
      • Design Patterns
      • Architecture Patterns
      • Binary search
      • PA/PG
   7. Create an Diagram
   8. Implement!

4. Git Github:

   • Git: local software
     • Distributed Logic
     • Works by using SHA1 for hash
     • Commits
     • Blobs
     • Trees
     • GitHub is a cloud based Git
     • git clone
     • git add (directory)
     • git commit -m (message)
     • git commit (will open text editor)
       • Use imperative verbs (subject): "Implements Functionality X"
       • Be more descriptive (Body)
       • Use reserved keywords (Futter) to redirect or versioning.
     • git push origin (branch)
     • git pull
     • git branch
     • git checkout -b (nova branch)
     • git log
     • git log --oneline
     • git checkout (branch or commit hash)
     • git config --global (properties or alias)
     • git stash
     • git merge
     • To pull request:
       1. Fork
       2. Clone
       3. Create new branch
       4. Push changings
       5. Pull requests that branch to Original one
     • Use SSH or Token to commit changings to cloud.
   5. Why Docker. How to Docker. Click here for more
      • Stays on a base OS, in general by virtualization controled by the "HyperVisor" (a system that limits and translates the systems call between systems).
      • A server can have more the one OS installed on top of it.(Generaly it is Linux Server)
      • An OS can have more than one container running in the same time.
      • The base OS (with Docker Engine) deploys automatically the containers as soons as it is demmanded
      • Docker do not needs to recopy a base OS so it is lighter and more performatic
      • It is a good match to Microsservices architecture
      • Brings Cloud to reality
      • The container needs to be compatible with the base Operational System.
      • Virtual Machines have more funcitionality and have more operations than containers, tho. To acess a server using ssh

ssh user@IP

To find server IP (you need to be inside the server):

ip a
