Mac: moving large amount of files off to external drive

I have tried to clean up my hard drive in preparation to upgrade to SSD. Moving files using Finder FAILS all the time an in the end you don't know what was copied and what was not.

I used rsynch tool because it it smart enough to copy ONLY new and changed files, so I can run it multiple times and transfer only the differences (delta).

$ sudo rsync -varpog --progress ~/Documents/SourceDir/ /Volumes/1TB_BU/DestinationDir/  Password:building file list ... 8943 files to consider.DS_Store      159748 100%  121.10MB/s    0:00:00 (xfer#1, to-check=8941/8943)2013-08-15 09.35.24.mp4    87290465 100%   22.57MB/s    0:00:03 (xfer#2, to-check=7445/8943)2013-08-15 11.51.18.jpg

Mac OS X: Yosemite: increase responsiveness

In this tutorial we will perform steps to increase responsiveness of the Mac.

Run CleanMyMac2 app

It is not a free option, but considering the amount of disk cleaned it is worth it.

Reduce Transparency

Apple > System Preferences > Accessibility > Display > Select "Reduce transparency"

You can toggle this on and off and you will see that you are not missing much.

Clean Notification Center

I don't ever use notification center so there is no reason for it to update

Apple > System Preferences > Extensions > Today

Clean Desktop

Move all items from Desktop to Documents, or where ever you wish.

Simplify Dock

• Minimize windows using "Scale effect" which is simpler than "Genie effect"
• NO to "Animate opening windows"
• YES to "Automatically hide and show Dock" - if you don't have to see it, don't show it

Speed up Finder

• since we are supposed to keep Desktop clean, it is a good default option to open
• YES to "Open folders in tabs instead of new windows
• NO to "Spring-loaded folders and windows"

Clean up your WiFi settings

http://osxdaily.com/2014/10/25/fix-wi-fi-problems-os-x-yosemite/

Turn off your WiFi

I am providing the following tasks in command line, but they can be done using Finder as well.

$ mkdir ~/Desktop/wifi_plist_backup

$ sudo mv /Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist ~/Desktop/wifi_plist_backup

Password:

SystemConfiguration $ sudo mv preferences.plist* ~/Desktop/wifi_plist_backup/

Re-start the computer, turn ON your WiFi

Java: interest rate calculator

In this tutorial we will write a simple command line Java program that calculates compound interest rate.

Create new Module (application)

Homework: add JavaFX UI to your app

Homework: add another method to calculate amount LEFT at the end of each year if given monthly amount is paid.

Java: Hello World

In this tutorial we will create the simplest of Java applications, an app that prints customary "Hello World" to the console.


Create new application module:

• FILE > New Module...
• Select Maven Module

Create new Java class "HelloWorld.java"

public class HelloWorld {
   public static void main(String[] args) {
      String myText = "Hello World!";
      // print to console
      System.out.println(myText);
   }
}

Run the app:

/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home/bin/java -
Hello World!
Process finished with exit code 0

IntelliJ IDEA: Create new Project (whole class) and new Modules (applications)

In this tutorial we will create a new Project (for the whole class) and new Modules (applications).




File > New Project...

For the whole class we will select Maven type.
Select your (newest Java SDK)
Next

This setting is for the WHOLE CLASS, we will create particular Modules (applications) later.

FINISH

At this point we have a new PROJECT with a first MODULE for the whole class.
You can use this module as a final project, or you will learn soon how to create new modules.

JavaFx: Hello World

In this tutorial we will print the customary "Hello World" to console and the the GUI using JavaFX.

• First we have to create a new Module (new application)
• select Maven app
• 
  

Type in group ID "edu.clc.cit137"
Type in artifact ID "javafx-hello"

Create a NEW Java Class (or File) named "HelloWorld.java"

Analyze the simple GUI in the image below.

Please type all Java code, click on the image to enlarge full screen.

In the second part of the code we have an EVENT handler for the BUTTON.
And layout of the widgets using HBox and VBox.

Finally, notice that package says "helloworld", however we are not in that package. Control click (command 1) on RED underline until options show up, select "Move to package..."

Run the app

IntelliJ IDEA: installation

In this tutorial we will install IntelliJ IDEA

Please download free IntelliJ IDEA

https://www.jetbrains.com/idea/download/


Select "Community Edition FREE" Current version is 14.x



After the installation you want to go to preferences and open your PLUGINS setting, some of the necessary plugins will be:

• Maven Integration
• .gitignore support
• JavaFX
• Terminal

Java: find jar

When you are looking for a given Java class, you can use this online database to locate jars:

Example, looking for log4j

http://www.findjar.com/index.x?query=log4j

Among others I get response:

[JAR] log4j-1.1.3.jar in log4j/log4j/1.1.3
[JAR] log4j-1.2.11.jar in log4j/log4j/1.2.11

Maven: installing apk, or arr, or jar in .m2

Sometimes you get a built artifact (apk, arr, jar) and instead of keeping it in your Downloads, or com up with a nice folder structure, you can simply put it in your Maven .m2 repository, that what it is designed for.

$ mvn install:install-file -Dpackaging=apk -DgroupId=com. mycompany.android -DartifactId= SomeApp -Dversion=1.4.42.0 -Dfile=/Users/uki/Downloads/SomeApp-1.4.42.0.apk

TextWrangler: formatting XML file

Go to directory where TextWrangle keeps all the scripts:

$ cd ~/Library/Application\ Support/TextWrangler/Text\ Filters 

Create a new file for XML formatting:

Text Filters $ touch FormatXML.sh 

This will open the new file in TextWrangler (or whatever editor you have set).

Text Filters $ edit FormatXML.sh 

Enter this text in that file and save:

#!/bin/sh
XMLLINT_INDENT=$'\t' xmllint --format --encode utf-8 -

Now you can format any XML by selecting TextWrangler menu: 

Text > Apply Text Filter > FormatXML
