Earth3D

Earth3D
Earth3D is a program that visualizes the earth in a realtime 3D view. It uses data from NASA,USGS, the CIA and the city of Osnabrück.


The program's features are
  • viewing the earth as a whole
  • zooming in until countries, cities and even single houses become visible (if I had such maps, so this is currently limited to the city of Osnabrück, Germany)
  • embedding external data like current earthquake positions or cloud data

Using Web Cameras in Linux

GTK+ UVC Viewer
This magnificent application can capture and view video from webcams and built in laptop webcams and strangely it gives 300% more high quality video than in Windows.
If you ask, this is my favorite software in Linux.

Lesson 3
Using Linux Terminal
 Linux Terminal is the same thing as the DOS prompt or CMD in Windows. It does the same thing.
But it has different commands.



Terminal Keyboard shortcuts

Tab  : Autocompletes from the cursor position.

Ctrl+a : moves the cursor at the beginning of the line (equivalent to the key Home).

Ctrl+e : (end) moves the cursor at the line end (equivalent to the key End).

Ctrl+p : (previous) recalls the previous command (equivalent to the key ).

Ctrl+n : (next) recalls the next command (equivalent to the key ).

Ctrl+o : executes the found command from research.

Ctrl+l : clears the screen content (equivalent to the command clear).

Ctrl+u : clears the line content before the cursor and copies it onto the clipboard.

Ctrl+k : clears the line content after the cursor and copy it in the clipboard.

Ctrl+w : clears the word before the cursor and copy it in the clipboard.


Ctrl+d : sends an EOF marker, which (unless disabled by an option) closes the current shell (equivalent to the command exit). (Only if there is no text on the current line)

Ctrl+c : sends the signal SIGINT to the current task, which aborts and closes it.

Ctrl+z : sends the signal SIGTSTP to the current task, which suspends it. To return to it later one can 
enter fg ['process name or job id'] (foreground).

Ctrl+x Ctrl+x : (because x has a crossing shape) alternates the cursor with its old position.

Alt+f : (forward) moves forward the cursor of one word.

Alt+b : (backward) moves backward the cursor of one word.

Alt+Del : cuts the word before the cursor.

Alt+d : cuts the word after the cursor.

Alt+u : capitalizes every character from the cursor's position to the end of the current word.

Alt+l : lowers the case of every character from the cursor's position to the end of the current word.

Alt+c : capitalizes the character under the cursor and moves to the end of the word.

Alt+r : cancels the changes and put back the line as it was in the history.

Lesson 2
Linux Filesystem Hierarchy

As in Windows, Linux does not have a C:\Windows directory or a C:\ drive! :O

The C:\ drive equivalent in Linux is "/" (forward slash), It is called the root directory.By "C:\ drive equivalent" I mean that system or as you know in windows, the system files are stored in "/" of Linux.


 Bin Directory
Open WINDOWS/System32/ in a Windows installed computer and you'd see a mass of exe files!. Same in here; the bin/ contains system binary files that are necessary for Linux.
In Linux bin directory is the equivalent for System32 directory in Windows.

Boot Directory
If you know how to go around in Windows, you'd have heard about a file named "AUTOEXEC.BAT"
Which is a file that is used by Windows Operating System in the boot process.And any dos command added to this file will get executed in the boot process.
Example: adding echo Hello! will show up a Hello! message when you start the computer.
Yes, you can also use it for destruction, if you're a lamer enough. The method was used in making the FIRST computer virus of the world. :)


Anyway; back to the point, Boot directory contains files that are necessary for the boot process of a Linux system.

Dev Directory
Don't get to this now, lets talk about it later.

Etc Directory
This is the most interesting directory in Linux for hackers. Because this directory contains a file with user names and encrypted passwords of the users in the computer.

The etc directory contains system configuration files of all kinds.

Home Directory
This directory contains equivalents of "My Documents" in Windows separated in to user named folders.
Example: If your user name in Linux is Mike, It contains all Documents, Music, Videos of Mike in the home directory.

Mnt Directory
All devices, hard drives, thumb drives are mounted here as a folder before it can be used. This is a automatic process.
So mnt directory contains mounted devices.

Lib Directory
lib directory contains equivalents of DLL files in Windows.

Tmp Directory
tmp directory contains temporary files.
Proc Directory
Contains real-time kernel processors in text files. Don't think about this now.
