Important Notes to Set Up Shared Folder and Clipboard in VirtualBox

Latest version of VirtualBox (4.3) has some new features whose every users wants. Two features which I really love are shared directory and shared clipboard (clipboard copy). By using shared folder feature, we can create some directories on host operating system which can be shared with guest operating system. Guest operating system can read data from the shared directory or write data to it so that host operating system can write or read the data. By using shared clipboard feature, we can copy some text data from host OS clipboard to guest OS and otherwise.
To use that features, we need some proper configuration process before and while running our virtual machine. I noted some points that is important and I hope we don't need to waste much time on configuration.

Download latest version of VirtualBox with its Guest Additions

You can download the installer from HERE. On installation process, you should include Guest Additions installation. Guest Additions is a sort of plugin for VirtualBox application which will be integrated with guest OS. When installation was finished, you can install your guest OS as usual.

Set Up Shared Clipboard

Before you run your virtual machine, you should configure General setting of your machine. On Advance tab you should specify type of sharing capability. You have to choose bidirectional option if you want to share data either from and into guest OS.

Set Up Shared Directory

Before you run your virtual machine, you should configure Shared Folders setting of your machine. You must specify shared directory path in your host OS and set your shared directory name. The shared directory will be accessed by guest OS according to its name. I suggest not to use any special character or space for its name.

Install VirtualBox Guest Additions on Your Guest OS

After you run your guest OS, you must mount Guest Addition installer from your host to guest OS. You can see complete instructions from Ubuntu Documentation here. You can also use these following steps.
  • On main window of virtual machine, you can press "Right Ctrl + D". This is default shortcut key to mount image of Guest Additions from VirtualBox application to virtual machine.
  • Autoplay application will run installation process after you mount the image. If the autoplay application doesn't run, you can run manually or choose proper installer application from mounting directory. For example in Ubuntu it will be on "/media".
  • You can also download image from repository by using this command "sudo apt-get install virtualbox-guest-additions-iso".

Set Up Shared Directory on Guest OS

After Guest Additions is installed, you can set up shared directory on guest OS. You can see complete instructions from Ubuntu Documentation here. You can also use these following steps.
  • Create directory for your shared directory on guest OS. For example, you use Linux as your guest OS, you can create "/home/your_username/your_directory". Your directory name should be different with shared directory name which you set up on VirtualBox manager before.
  • Mount shared directory to directory that you are determined. 
  • On Linux as guest OS, you can use "sudo mount -t vboxsf -o uid=$UID,gid=$GID shared_directory /home/your_username/your_directory". 
  • On Windows as guest OS, you can use "net use x: \\vboxsvr\shared_directory".
  • On Linux as guest OS, if you get error message "Protocol Error" when you mount the shared directory, you can try to mount shared directory by this command "sudo mount.vboxsf shared_directory /home/your_username/your_directory".
  • If you can't run "mount.vboxsf" command, you should install the app first by this command "sudo apt-get install virtualbox-guest-utils".

Rangkaian Sensor Infrared dengan Photo Dioda

Keunggulan photodioda dibandingkan LDR adalah photodioda lebih tidak rentan terhadap noise karena hanya menerima sinar infrared, sedangkan LDR menerima seluruh cahaya yang ada termasuk infrared. Rangkaian yang akan kita gunakan adalah seperti gambar di bawah ini. Pada saat intensitas Infrared yang diterima Photodiode besar maka tahanan Photodiode menjadi kecil, sedangkan jika intensitas Infrared yang diterima Photodiode kecil maka tahanan yang dimiliki photodiode besar. Jika  tahanan photodiode kecil  maka tegangan  V- akan kecil . Misal tahanan photodiode mengecil menjadi 10kOhm. Maka dengan teorema pembagi tegangan: V- = Rrx/(Rrx + R2) x Vcc V- = 10 / (10+10) x Vcc V- = (1/2) x 5 Volt V- = 2.5 Volt Sedangkan jika  tahanan photodiode besar  maka tegangan  V- akan besar  (mendekati nilai Vcc). Misal tahanan photodiode menjadi 150kOhm. Maka dengan teorema pembagi tegangan: V- = Rrx/(Rrx + R2) x Vcc V- = 150 / (150+10) x Vcc V- = (150/160) x 5

Raspberry Pi Bluetooth Connection

Raspberry Pi 3 provides built-in bluetooh module. Latest Raspbian has been bundled with tools for enabling bluetooth connection. Bluetooth icon will be showed up on top right corner of the desktop. It's a tool to discover available bluetooth devices and connect Pi with bluetooth devices. It is easy to connect any bluetooth-enabled electronic device with Pi. But, sometimes Pi will fail to make a connection especially for bluetooth device which has no standarized services. From terminal, we can use bluetoothctl tool to scan and connect with a bluetooth device. You should make sure that BlueZ protocol stack has been installed by running $ apt-get install bluez Run bluetoothctl to enter the tool command window Turn the power on by running power on (Optional) You can set AutoEnable=true in /etc/bluetooth/main.conf if you want to make the bluetooth auto power-on after reboot. Run devices to see which devices have been paired Run scan on if your desired device has not pair

How To Use Git in Netbeans

Git is a popular version control application nowadays. Recently I have created a note about its differences with SVN and how to use it in Eclipse . There are many Git client tools. But I just want to show how to use Netbeans built in Git tools. It makes development process easier because it has been integrated with the IDE. Create Remote Git Repository We need remote Git repository so everyone can store or receive any revision or updated files through the networks. We can setup our own Git server or use public Git server like Github . In this note, I use Github. 1. Create an account in Github and create an empty Git repository Create an empty public repository in Github 2. Get the remote repository link Your Github Repository URL Create a New Project in Netbeans and Create Local Git Repository After we have a remote Git repository, we can create a project which will be stored to remote repository. We also need to create local repository before we can push

Run Python Scripts Using PHP in a Linux Environment

How to run python or other scripts using PHP or other popular web programming languages in a Linux environment? Problem We want to access PHP program through a web server application (Apache/Nginx). The PHP program need to run other scripts stored in the same machine. Sample Problem PHP program is located in /var/www/html/index.php Python program is located in /var/www/html/capture.py Python program will access Pi Camera, capture an image, and store it in /var/www/html/assets/photo.jpg Solution index.php should access and run capture.py script. The script is as follows: $output = shell_exec("python /var/www/html/capture.py"); Execution of external program using shell_exec() or exec() will block the program. The next line of PHP codes will be run after external program returns an output. So, we shouldn't run excessive amount of external program. Clients will wait too long on their browser. If our application actually need many external pr
