Software required for participation• Application for web conferencing system• We use Cisco Webex. In a small group of hands-on, if the lecturers and theparticipants agree, it may be Zoom or Microsoft Teams.

• Linux environment• The X Window System (X11) must be running.
• There is no direct calculation in this environment. It is only used as a terminal for
logging in to a PC cluster.
• Here, we recommend the environment where VMware is installed and Ubuntu isinstalled there. We will not respond to other questions. (It does not support
Mobaxterm or WSL. )• The Mac comes with a Linux environment out of the box, but you need to have
XQuartz installed. There are some cases where the software does not start on
Mac due to the graphic library. In that case, we cannot respond to such questions.

• Slack: Chat tool for questions and support• The web conferencing system uses only text, but Slack allows you to paste photos
and various other data to communicate with the lecturers.

• If you wish to take the Materials Informatics Course, you are required
to install the latest version of jupyter Notebook and Python3 by yourself,
so please check the website.

Image of online hands-on environment• It is desirable to have two displays. (Theexample is a notebook PC (12.1 inch) +one display (24 inch), Web conferencing
system screen, Linux environment andSlack screen.)• One PC is good. It can be useful to copy
and paste what is pasted into a web
conferencing system chat or Slackcomment to the Linux command line.
• If you don't have a display and you want
to do it on two PCs, it's better to operate
the Linux environment and Slack on thesame PC.

What is Slack?

https://slack.com/intl/ja-jp/• A high-performance chat tool that allows you to make groupchats, one-on-one messages, and voice calls.
• It can be used synchronously with various OSs. (It's also inUbuntu.)• If we actually use it, we will invite you by email from us.
• It is an auxiliary tool used to carry out the training efficiently, souse it as needed.
• If you use Slack for the first time, please read the introduction
on the official website.

Easy Linux environment

Notice• I only know the level that I can use in my research without
any inconvenience. I'm not a person who loves PCs andknows everything.
• Ask those sites and those people for maniac details.
• Therefore, it is not possible to give a systematic explanation.
It's just an empirical story I've used so far.
• Please install at your own risk. We do not take any
responsibility for that.

Install VMware Workstation
15.5 player

Linux environment construction using VMware• Since it is basically an operation inside a virtual disk, it does
not affect the Windows system. So if you don't like it, you canstop right away.
• Linux is installed here, but any OS can be installed.
• Since it runs on Windows, you can work in parallel withnormal Windows operations.
• There is also Oracle VirtualBox, a software that can do thesame, but this is not supported.

If you search for “VMware player” onGoogle, this site will appear at the top.

When you execute the downloadedfile, the following installer will start.

Follow the installer and proceed steadily.

Installation finishedAn icon like the one below is created on thedesktop. Click this to launch VMware Workstation
player. (Or select from the menu bar)

When you start it, you will be asked for your email address for non-commercial
use only for the first time, so enter it to continue

Create a new virtual machine, but download
the Ubuntu iso file to be installed there.

This figure is after
installation, so there isnothing in this field at
the beginning.

Download the Ubuntu CDimage fileIf you search for "Ubuntu" on Google,
this site will appear at the top.

クリックすると、最新版のサイトに行くClick here to go to the latest version of thesiteAs a result of clicking, it is saved as follows in
an appropriate download directory (“Download”
by default).

Select the Ubuntu CD image file with
VMware player and start the Ubuntu
installation on the virtual disk

Click here tocreate a new
virtual machine.

Click Browse and specify
the downloaded disk image(file with extension iso).

This is like an initial value
and can be changed afterinstallation. (You can dowhatever you want withyour settings.)

It seems that the default is
Ubuntu 64-bit, so if you
plan to install some OS in
the future, change it so that
it is easy to understand. Adirectory with this namewill be created.

The default virtual disk
size is 20GB, but you canchange it appropriately.
You can increase it asmuch as you like withthis setting.
The default is "Split thevirtual disk into multiple
files", but set it to "Storethe virtual disk as a singlefile".

Other than that, don't worry
too much and leave it as "OK"(probably). After that, theinstallation of Ubuntu willproceed without permission,and preparations arecompleted on this screen. (Inprevious versions of memory,the default was 1024MB, but
the default has changed withthe times.)

Do what you can do during installation.

Ubuntu installation finishedもし、Disadvantages of using Ubuntu with VMware• Files on Windows and files on Ubuntu cannot be shared.
• Backups of files on Ubuntu cannot be placed directly on thePC (Windows side) you are currently using, so you need tosave them on another medium. It is possible to recognize by
directly connecting the USB to the PC or connecting the HDD.
• Since it runs on Windows, I feel that it depends on theperformance of the PC. (It is an individual impression.)• I've shown Ubuntu 20.04 here, but 18.04 may be better. (LTS:Long Term Support until April 2023)
