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".

Configuring Swap Memory on Ubuntu Using Ansible

If we maintain a Linux machine with a low memory capacity while we are required to run an application with high memory consumption, enabling swap memory is an option. Ansible can be utilized as a helper tool to automate the creation of swap memory. A swap file can be allocated in the available storage of the machine. The swap file then can be assigned as a swap memory. Firstly, we should prepare the inventory file. The following snippet is an example, you must provide your own configuration. [server] 192.168.1.2 [server:vars] ansible_user=root ansible_ssh_private_key_file=~/.ssh/id_rsa Secondly, we need to prepare the task file that contains not only the tasks but also some variables and connection information. For instance, we set /swapfile  as the name of our swap file. We also set the swap memory size to 2GB and the swappiness level to 60. - hosts: server become: true vars: swap_vars: size: 2G swappiness: 60 For simplicity, we only check the exi

Master Slave Replication to Automatically Backup Your MySQL Database

We can make backup for some databases by periodically running a kind of dump query, like mysqldump in MySQL. That's the simplest method but it can drain our server resources and it's not suitable for large databases. MySQL comes up with master-slave features that allow you to replicate your database to another location (slave). This mechanism enables MySQL to generate a log file which records any action performed to the database. Then, that action will be run in slave database too. For example, we have two database servers with IP address 192.168.0.1 (Master) and 192.168.0.2 (Slave). 1) Configure my.cnf in master server # Master Settings # locate where the changes record will be stored log-bin = /var/log/mysql/mysql-bin.log # set unique ID for master database in master-slave network (up to you) server-id = 111 innodb_flush_log_at_trx_commit = 1 sync_binlog = 1 # select database which will be replicated # by default system will log all databases binlog-do-db =

Installing VSCode Server Manually on Ubuntu

I've ever gotten stuck on updating the VSCode server on my remote server because of an unstable connection between my remote server and visualstudio.com that host the updated server source codes. The download and update process failed over and over so I couldn't remotely access my remote files through VSCode. The solution is by downloading the server source codes through a host with a stable connection which in my case I downloaded from a cloud VPS server. Then I transfer the downloaded source codes as a compressed file to my remote server through SCP. Once the file had been on my remote sever, I extracted them and align the configuration. The more detailed steps are as follows. First, we should get the commit ID of our current VSCode application by clicking on the About option on the Help menu. The commit ID is a hexadecimal number like  92da9481c0904c6adfe372c12da3b7748d74bdcb . Then we can download the compressed server source codes as a single file from the host.

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

Resize VirtualBox LVM Storage

VirtualBox is a free solution to host virtual machines on your computer. It provides configuration options for many components on our machine such as memory, storage, networking, etc. It also allows us to resize our machine storage after its operating system is installed. LVM is a volume manager in a Linux platform that helps us to allocate partitions in the system and configure the storage size that will be utilized for a specific volume group. There are some points to be noticed when we work with LVM on VirtualBox to resize our storage. These are some steps that need to be performed. 1. Stop your machine before resizing the storage. 2. Set new storage size using GUI by selecting " File > Virtual Media Manager > Properties " then find the desired virtual hard disk name that will be resized. OR , by running a CLI program located in " Program Files\Oracle\VirtualBox\VBoxManage.exe ".  cd "/c/Program Files/Oracle/VirtualBox" ./VBoxManage.exe list

Setting Up Next.js Project With ESLint, Typescript, and AirBnB Configuration

If we initiate a Next.js project using the  create-next-app tool, our project will be included with ESLint configuration that we can apply using yarn run lint . By default, the tool installs eslint-config-next and extends next/core-web-vitals in the ESLint configuration. The Next.js configuration has been integrated with linting rules for React and several other libraries and tools. yarn create next-app --typescript For additional configuration such as AirBnB, it is also possible. First, we need to install the peer dependencies of eslint-config-airbnb . We also add support for Typescript using eslint-config-airbnb-typescript . yarn add --dev eslint-config-airbnb eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks yarn add --dev eslint-config-airbnb-typescript @typescript-eslint/eslint-plugin @typescript-eslint/parser After that, we can update the .eslintrc.json file for the new configuration. { "extends": [ "airb
