The exercise contains the following parts:
- Make your own Linux live boot stick. Try it with some other computer than the ones in school lab. This part doesn’t require installing the OS on your computer – if you do so, make sure you do proper backups first
- List of the hardware of your test computer (’sudo lshw -short -sanitize’)
- Install three new software that are new to you. Try each of them in their mainly tasks
- Check what licenses the installed softwares use. Explain shortly, what rights and duties those licenses provide for you as an end-user
- List the software you use for your daily usage (ie. MS Word), their main purpose (ie. text preparation) and a controversial free Linux-software (ie. Libreoffice Writer). If a program doesn’t have any free Linux-counterparts, list it anyway.
First I start with creating the live boot stick and test the booting with my Lenovo Thinkpad T570 laptop and windows 10 installed (secure boot is already turned off)
Sat 25.8.2017 18:49:00
Started with downloading a latest image of a Xubuntu OS from the xubuntu website.
I’m going to pick the latest LTS-release availabe and use an HTTP-download source from Sweden proxy. The latest stable 64-bit release appears to be xubuntu-16.04.3-desktop-amd64.iso
The download took total of 13 minutes for a 3.7 Gb ISO-file, so apparently it’s a pretty slow to fetch an image file via HTTP-download, since it’s only provide from a one source at a time. During the download, the average download bandwith jumped between 3-8 Mbps.
Now it’s time to install an USB live stick creator application and, for Windows 10 operating system I’m currently using, I chose Rufus not only because it’s free and open source application, but also the UI is very simplified and mimics
the standard window of the Windows drive property popup, which makes it more intuitive to use in the Windows environment.
after downloading, I tried to open Rufus, but for some reason, it seems to hang on the background and doesn’t seem to load any visible UI. Even the task manager is unable to kill the process, so I believe the startup process is stuck somewhere.
After looking around the cause, I found out that the File History software I enabled earlier, before starting to studying this case, is still writing a mirror copy of the current personal files into my external drive and does that reeeally slowly
(as any other windows pre-installed backup program, it doesn’t show any progress bar to estimate, when it would be done with it’s job or at least indicate, it’s not
stuck in). After killing the backup process (I’ll just finish it up with some other tool later) Rufus started to work again, so I believe it had hard time on identifying
my external hdd during the backup process.
Next thing would have been finding the path of my downloaded Xubuntu iso-file, but after checking the download history, I found out that it apparently failed after all. This time I chose to download a more trustworthy torrent file and start a cluster download by using this very good, open source bittorrent-client Deluge, which is available on multiple
platforms, including several Linux distros, Mac OSX, Windows and FreeBSD
after having a break, I noticed my torrent-download being completed and it turned into a seeding mode.
Now back to Rufus..
From the screenshot, you can see that I have a 7.8GB sized USB stick attached into a D- drive letter and for a partition scheme I’ve chosen ”MBR partition scheme for BIOS or UEFI” so it can support both BIOS and UEFi boot options.
”File System” has to be FAT32, otherwise it won’t support partitions sized over 1GB.
”Cluster Size” of 4kb is just fine, since I don’t happen to have a volume over 16TB.
”New Volume Label” is fine with 7.8Gb, therefore it uses the entire capacity of the usb stick.
”create a bootable stick with” will be ISO Image, since the downloaded file is formatted with ISO-packaging. By clicking the the disc image next to the dropdown menu, I can choosethe path to the ISO-file.
here I’m going to pick the Xubuntu image I torrented.
now it says ”Using image: xubuntu-16.04.3-desktop-amd64.iso” at the bottom, which means we are ready to start burning, so I just click ”Start” and Rufus gives me the following popup:
apparently Rufus is capable of analyzing the bootloader used by the chosen image, and now it recommends me to connect internet for downloading the most
latest version of syslinux-bootloader. Probably this is not recommended, since a bootloader is often made bootable for that certain iso-file, but
just out of curiosity I’d like to see, how the Rufus handle such situation, so I just click ”yes”
Now the Rufus is telling me that the file is typed as ”ISOHybrid” and I can burn it as ISO-mode or DD-mode. Here I believe it’s referring to a dd-application
from unix operating systems, that is used for writing disks and disk images bit-by-bit into a chosen output (i.e. another disk). Therefore I’m curious to see
this ISO-option it’s offering here.
Now the Rufus seems to be ready with writing the ISO-file and to verify that, we can look inside the drive
boot stick seems to be ready for the boot test. I have already disabled secure boot on my laptop, so I can try immediately to boot with the stick
I was able to boot, but the resolution of the screen seems to be a bit outfitted. Probably I need to install some external graphic drivers to support Nvidia GPU.
The next thing is to test out the hardware recognition by using the following command
xubuntu@xubuntu:~$ sudo lshw -short -sanitize

Apparently it shows the system using the external Nvidia GeForce 940MX chip for graphics display, so that confirms that Xubuntu is missing the proper Nvidia drivers. I have to note that when I’m about to actually install a Linux distro on this laptop.
The next step is to install 3 new software by using a package manager,
so we start with sudo apt-get update.
I have to say, I’ve been using Linux, and especially Ubuntu, for a several years, so I find it hard to think of any new software I haven’t yet installed, so I just ended up looking for the most favorite programs listed on an Internet top ranking lists like this one http://www.omgubuntu.co.uk/2016/12/21-must-have-apps-ubuntu
and pick 3 software that I haven’t yet heard of.
After looking for a while, I ended up picking these three candidates:
– Ubuntu cleaner
– Clementine Music Player
Apparently for Neofetch, there’s no official Aptitude repository available, so I have to deal with the installation in an old-fashioned way: downloading sources packed in a tarball:
1. wget https://github.com/dylanaraps/neofetch/archive/3.2.0.tar.gz
2. tar xzfv 3.2.0.tar.gz unzipped neofetch-3.2.0 folder containing the actual source
3. cd neofetch-3.2.0 && ./neofetch makes it run
I have to admit, it’s pretty clear and works!
the next software is called Ubuntu Cleaner and again, this candidate doesn’t have any official installation repo on Aptitude,
but it does offer a custom ppa, if you trust them enough. You can also download the actual deb-package or sources from their github page.
Let’s try the deb-package, you can either use software center to let it install the package, or simply use command dpkg -i ubuntu-cleaner_1.0.4-1_all.deb
First I tried opening the deb-file with Software Center (picture above), but the install button was unresponsive for some unknown reason, so I ended up using terminal and dpkg-command.
when running dpkg, it encountered a problem with unmet dependencies, but those can be installed by calling sudo apt-get -f install and then dpkg -i ubuntu-cleaner_1.0.4-1_all.deb again.
clementine is the last application and it was available on the official repos. I just commanded sudo apt-get install clementine and it was immediately ready to use. Tested out a sample music file and it appears to play music, so at least my speakers do work.
Continuing the steps with identifying the licenses of the previously installed three softwares.
first, the Ubuntu Cleaner says on it’s github page, that the software is licensed with GPLv3.
NeoFetch on the other hand says on their github page, that it’s licensed under MIT , which makes it possible for me to release my own modified version of this app as a closed propiertary software.
Clementine says on their web page https://www.clementine-player.org/ that it’s licensed with GPLv3
For GPLv3 softwares, as a user, I have the four principles as a rights to use these products (run,study, modify, redistribute and sell copies), but it means also
that I have to pass these rights to my modified, redistributed product as well. With MIT-license, I can also take the sources, make a modified application
and keep the sources to myself if I want and relicense the software I have made.
The next task is to list my mostly used applications and their alternatives on free linux-side.
The softwares I mostly use are work-related stuff, which are
– skype for business
– Intellij IDEA
For skype for business, apache seems to have it’s own openmeetings teleconference application with the Apache Software License version 2.0
Intellij IDEA Community Edition is published under Apache Software License 2.0 and it’s available on windows, osx and linux. The community edition, on the other hand, doesn’t support Java and Spring development, therefore a true alternative would be an easyeclipse , which combines open parts of the Eclipse IDE and the available open source plugins and distributes the migration under GPL-license.
Slack is obviosly not a free software and after googling around, I happened to find a chat-client, that advertises itself as an open-source alternative for slack and it’s called MatterMost. apparently, it’s community version is licensed under MIT.
Telegram provides the source codes for all of their client applications https://telegram.org/apps with GPLv2 licenses for Android, iOS, OSX, WP and Telegram CLI and GPLv3 for web browser client, Desktop client (OSX,Windows,Linux). Therefore there is no need to find an alternative for this product.
