How To Install Ubuntu 20.10 Groovy Gorilla

13 hours 57 min ago

This tutorial explains Ubuntu 20.10 Groovy Gorilla computer installation. You will prepare at least two disk partitions, finishing it all in about twenty minutes, and enjoy! Let's start right now.

About This Tutorial


This tutorial is practicable for normal installation as well as dualboot, UEFI, and even external drive ways. 

  • Normal: most computer users will need this.
  • Dualboot: users who wants both Ubuntu and Windows in one computer will need this. This needs separate partitions prepared beforehand.
  • UEFI: users with >=2011 computers will need this. This needs one additional partition called efi.
  • External: for users who want to install, not only make bootable, Ubuntu into a pendrive or external hard disk drive. The only difference is where you put the bootloader on.


Preparations


Ask experienced knowledgeable computer users near you guidance in following this if you have no prior experience in partitioning and doing backup.

Partitioning example

First preparation, Download Ubuntu 20.10 and create a bootable flash disk drive using tools like Unetbootin or Rufus, GNOME Disk Utility, or GLIM.

Second preparation, with GParted on LiveCD, create three hard disk partitions: 

  • first one tiniest, a FAT32 by 100MegaByte with label FOR EFI;
  • second one a little bit larger, a FAT32 by 1GB with label FOR SWAP; and
  • third one the largest, a FAT32 by >=20GB with label FOR ROOT.

For Dualboot mode, make sure you properly backed up important data from Windows and its data partitions to external storage drive. For BIOS Legacy users, you do not need and simply ignore the making of EFI partition above. For UEFI users, you do need to make those three partitions. For disk partition size, I recommend a 100GigaByte ROOT for serious and permanent use. For external installation, you can install Ubuntu into a USB Flash Drive or similar device by choosing correct bootloader location as explained in partitioning section below.


Booting & Entering Setup

Make sure your BIOS ready, now boot up your computer to USB > then, select Try It instead of Install It on Ubuntu selection screen > you see a pink orange desktop with a gorilla picture, that is "preview" or LiveCD session, then double click Install Ubuntu 20.10.

 1. Select Language


First page, select English and continue.

2. Select Keyboard


Second page, select English (US) and continue. You can change it later to Arabic, Japanese, Chinese, etc. anyway.

3. Select Networking


Third page, select 'I don't want to connect' and continue.

4. Select Normal


Fourth page, select Normal Installation instead of Minimal and continue.

5. Select Manual Partitioning


Fifth page, select Something Else also known as Manual instead of others and continue. You might be asked to do unmounting then do it.

6. Create Disk Partitions & Bootloader


Here you will utilize 3 partitions you have created beforehand.

  • 1. Create EFI partition(*): click the smallest sized partition > Change > switch Use as: to EFI System Partition > OK.
  • 2. Create SWAP partition: click the middle one > Change > switch Use as: to swap > check mark Format the partition > OK.
  • 3. Create ROOT partition: click the largest one > Change > switch Use as: to EXT4 Journaling Filesystem(**) > check mark Format > select mount point / > OK.
  • 4. Select bootloader install(***): choose the same disk address where you made ROOT partition above, for example, choose bootloader /dev/sda if your ROOT is /dev/sda1.   
  • 5. Click Install Now. 

 

*) BIOS Legacy users do not create this.

**) Choose EXT4 for hard disk, but instead choose EXT2 for installation into USB flash disk. 

***) For external install, do not choose internal hard disk address but choose your external drive address where your ROOT partition is made.


7. Fill User Profile


Here you determine own timezone then username & password pair.

  • 1. Timezone: click a point on the world map to choose yours. As example, mine is Asia/Jakarta, Indonesia. Go next. 
  • 2. Username: determine username > determine computer's name > determine password > determine either Login Automatically to mimic most Windows computers (for convenience) or Login with Password as usually Ubuntu user's do (for security) > go next.


8. Wait


Now you will only need to wait up to fifteen minutes while enjoying beautiful slideshow. You can have a cup of coffee or chit chat with friends here. The secret is, here thanks to you chose Try It (aka LiveCD) earlier, you can even write documents or play audio as you can run all the programs on your screen.


Finish


Once finished, Ubuntu 20.10 says Installation Complete so click Restart Now to enjoy your new computer. Congratulations!

Lenovo ThinkPad Booting GNU/Linux USB

Thursday 22nd of October 2020 01:23:00 PM

Lenovo ThinkPad users can boot USB drives finely. As Ubuntu Buzz often publishes booting articles, now let's learn how to practice that on computers using ThinkPad as example. By making this tutorial I hope I give abilities to all computer users who didn't know yet they can do this amazing thing. Let's go!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.


What Is Booting

Computers work by a mechanism called booting that is finding the storage and reading the operating system. When user starts up his computer he does booting. Operating system is an important software set stored in storage without it computer does not work. On PC and laptop, an OS normally stored in hard disk drive (HDD) however in fact there were OSes stored in floppy disk drive also known as diskette (FDD), in Compact Disc (CD) or Digital Versatile Disk (DVD), and in modern days even in USB flash drive (USB).

What Is a USB Drive

A USB storage device sometimes called USB pendrive, USB stick, or flash disk, or whatever else. It is a digital storage that connects to computer through USB standard.

Goal

To run an operating system stored in a USB drive.

Making Bootable USB

An operating system should be inserted into a bootable drive in order to make computer runs it. To create one, use one of these tools.

 

Insert Drive

Plug your pendrive stick to USB port on your computer.


Start The Computer

Turn your computer on. 

Setup BIOS

(1) Press special key to enter your BIOS. As example, on Lenovo ThinkPad it is F1, on Acer it is F2, and on ASUS it is Del, on your computer it depends on what message appears quickly under manufacturer logo when you boot up.

(2) Go to Booting section and make sure computer chooses USB as its first device to boot before HDD and CDROM. 

(3) Save and Reboot. On most computers, the key is F10.

Run Operating System

Now you see GNU Operating System runs. Your screen should see the appearance of GNU/Linux distro you run. On my example my Lenovo ThinkPad runs Ubuntu.


Shutdown and Restart Quickly

Different to Windows or macOS, GNU/Linux has special keyboard shortcuts called Magic SysRq. It works as long as kernel is staying at the memory and not in panic condition. To shutdown instantly, press Alt+Printscreen+REISUO. To restart immediately, press Alt+Printscreen+REISUB. These Magics work with all Debian and Ubuntu distros family. Known distros without these are Fedora and openSUSE.

Setup KOrganizer with Operation Tulip Online Calendar

Thursday 22nd of October 2020 11:14:00 AM

Anyone using Kubuntu will see KOrganizer the best desktop calendar and anyone knows internet knows NextCloud technology a complete solution to live online. Now we find Operation Tulip a generous online service for data storage and calendar based on that technology. This tutorial explains how to synchronize your desktop and your online calendar the easy way.

Subscribe to UbuntuBuzz Telegram Channel to get article updates.About The Tools


KOrganizer
is a complete desktop calendar similar to Mac's or Windows' built-in Calendar application. It works with multiple accounts and supports the popular iCalendar format. It supports colors and categories and is able to work offline.  It is developed by KDE.

NextCloud is latest computing technology in the field of online storage developed from the earlier one named OwnCloud. Any company or organization with enough capacity can make their own Google Online Services such as office suite, storage, mail, calendar, video call, and more simply by installing this on their server. NextCloud is Free Software. It is founded by vice president of KDE.

Operation Tulip is an European online service that is based on NextCloud technology. They claim to be fully Free Software based, own complete control over their hardware, and promise to never sell or share user's data.


Goal


Synchronizing KOrganizer with Operation Tulip.

Register


In order to use Operation Tulip, you must register first. Note: after registering, I suggest you to save every account in your password manager app.  


Pair

 

In order to connect KOrganizer to Operation Tulip, you must pair them.

  • With browser, login to your Operation Tulip.
  • Go to Calendar.
  • At the first time, you see only a blank month with one Personal section.
  • Click Settings & Import on lower left and scroll down until you see CalDAV.
  • Click Copy Primary CalDAV Address.
  • The URL copied.
  • Run KOrganizer.

Add Calendar by right click on lower left box > select DAV Groupware Resource > on the dialog appears enter your Operation Tulip username and password > select Configure Resource Manually > Finish > a 2nd dialog appears > on General Configuration, type Display Name: Operation Tulip; Username: your username; Password: your password > on Server Configuration section, click Add > 3rd dialog appears > on Remote Calendar Address section, paste the URL you copied from Operation Tulip > on Discovered Collections section, click Fetch and it lists out online calendars you have > OK > back to 2nd dialog > on Synchronization section, uncheck Limit CalDAV Retrieval Time > OK > KOrganizer paired.



Schedule

 

Creating schedules on web will be seen on desktop. Reversely, creating schedules on  desktop will also seen on web. Now rest easy and start coloring your month.

Here's my KOrganizer on desktop:

 
Here's my Operation Tulip with only one calendar I display:

Groovily Going Ubuntu 20.10 Gorilla

Wednesday 21st of October 2020 04:05:00 PM
Groovy Gorilla is the birth name of Ubuntu 20.10 the next generation computer operating system with latest technology. As its version number suggests, it is the October release this year after the April one 20.04 LTS as traditionally Ubuntu released twice a year since its first inception in 2004. Now I have the chance to see what’s new in Groovy for dear readers who are curious plus how it works on Lenovo ThinkPad. Let’s enjoy! Subscribe to UbuntuBuzz Telegram Channel to get article updates.


About This Article


I run Groovy with my laptop Lenovo ThinkPad T430.

  • Intel Core i5 Quad Core @ 2.6GHz
  • Intel HD Graphics
  • 4GB of RAM
  • 320GB hard disk
  • Centrino wifi
  • Bluetooth
  • Touchpad and TrackPad


OS Specification


  • Name: Ubuntu
  • Version: 20.10
  • Support lifespan: 9 month until July next year
  • Desktop environment: X11, GNOME 3.38
  • GNU: GRUB 2.04, Coreutils 8.32, Bash 5.0, GnuPG 2.20, GNOME, Tar 1.30, Gzip 1.10, Debugger 9.2, Wget 1.20
  • Kernel: Linux 5.8
  • Tools: systemd 246, rsync 3.2.3, apt 2.1.0, dpkg 1.20, snapd 2.47, packagekit 1.1.13
  • Applications: LibreOffice 7.0, Mozilla Firefox 81, Mozilla Thunderbird 78, Remmina 1.4.8, Transmission 3.0


Image


Computer operating systems are distributed in image file that name mostly ended with .iso or .img. Ubuntu is also distributed as images we can download, run, preview, and install, and pass it on to our friends. For the 20.10 Groovy Gorilla I use the image not officially released yet or more specifically “final freeze” development version. The image file is named groovy-desktop-amd64.iso by size 2.8GB dated 15 October 2020.


Ubuntu Computers


Right now Dell, Lenovo, Star Labs, and LaptopWithLinux sell their Ubuntu PCs and laptops preloaded. We can now purchase ThinkPadand XPS high end laptops with 20.04 LTS. We have choices with LabTop and Clevo lines of laptops preloaded with Ubuntu too. Not only them, fortunately Tuxedo and Slimbook, the vendors who made Kubuntu Focus hardware a reality, sell their computers with Ubuntu preloaded too. We can expect they all OEM vendors will ship Groovy Gorilla as well later. The availability of OEM computers like that will lift the burden on end-users to do manual installation just like what manufacturers do with Windows computers for decades.


Booting


Ubuntu Groovy gives three installation options namely Ubuntu, Ubuntu (safe graphics), and OEM Install (for manufacturers). 


Automatics
Once installed, Ubuntu Groovy just works on my ThinkPad laptop. All hardware detected automatically. This will make Microsoft users happy.
Appearances


Here’s how Groovy Gorilla looks like.


Identity


Ubuntu has unique identity just like Microsoft Windows and Apple MacOS have their owns. Groovy user sees their computer by its looks. Top and left panels with such Yaru colors blended between purple orange. Now all icons are displayed equally without classification into Frequent and All. Now icons arrangements can be drag and dropped manually.



Applications


Just like any earlier Regular releases, 20.10 updates its applications so they are the latest and greatest right now. As you can see below, it brings LibreOffice Seven the greatest Free Libre Open Source Software office suite today along with latest Rhythmbox Player, Mozilla Firefox and Thunderbird, and built-in Ubuntu Desktop Guide.


Now making documents got more excitements thanks to Seven.


Connectivity


Networking works smoothly. Wifi, ethernet, and bluetooth doing their jobs seamlessly on my ThinkPad T430. Everything is instantly detected once Groovy has been installed without requiring additional driver discs or such.

Login Screen
Here's how we logging in to Ubuntu computer on 20.10.


As simple as always without any noticeable changes. However, technically speaking, Ubuntu by default runs under X11 mode while Wayland mode is available to choose from the gear button as depicted in picture above.

Installation


Ubuntu successfully keeps its easy install tradition. Imagine to install an OS only under fifteen minutes, that’s Ubuntu for you, without hassle of separate driver discs neither antiviruses. Groovy finishes very quickly continuing its great tradition.



Resource Utilization


Surprisingly, Groovy uses only about 800MiB memory after a fresh install far better than 1000MiB on the previous releases with GNOME desktop. Its CPU utilization is also quiet.  It even works well on a virtual machine with 2 CPU and 1.5GiB memory done with the friendly tool AQEMU.


ThinkPad Specials 


For Lenovo users especially ThinkPad owners, as i use T430 here's my experience with Ubuntu 20.10. It is a happiness.

  • Touchpad: works.
  • TrackPoint: works, the point and its three red buttons.
  • Keyboard: works, plus Fn and Ctrl keys can be swapped from the BIOS.
  • Fn combinations: work
  • Special keys: everything works: mute, up/down, mic, 
  • Speakers: work, both left and right.
  • Indicators: work, wifi - disk - battery - moon.


Afterword


I am excited to review Groovy. I am satisfied. As we could see in this article, everything just works as expected. I wish you find same excitements with Groovy. What do you think about Ubuntu 20.10, o dear readers?

How To Install QStarDict with English-Indonesian on Ubuntu 20.04 LTS

Saturday 17th of October 2020 04:13:00 PM

There was a really good desktop dictionary program StarDict available on Ubuntu for years. It means a lot for education! Unfortunately, it was no longer available on 18.10 "Cosmic Cuttlefish" and later since it got discontinued. That means 18.04 LTS users can still install it but 20.04 LTS users lost it. Fortunately, we have its modern replacement named QStarDict with same functionalities available for 20.04. This tutorial explains how to get it to your system and supplies example in adding dictionary data and finally how to use it.

 

 Thanks to free software community StarDict now lives again!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.

 Install QStarDict


Do command line below:

$ sudo apt-get install qstardict festival

Add Dictionary Data
StarDict divides its program and its dictionary data to work for you. It means after you install the program you must install the dictionary files yourself. There are so many language files available such as Indonesian-English as well as English-Indonesian since StarDict had been around since very long time. QStarDict works the same way. Here's how to add dictionary data by example Indonesian><English.
  1. Download English-Indonesian dictionary files at GitHub
  2. Extract it.
  3. Copy its folder contents.
  4. Paste them into your ~/.stardict/dic/ folder. 
  5. If it doesn't exist then create it and paste them. 
  6. Correctly placed items look like picture below. 

Run QStarDict


Find QStarDict on your start menu and run it. Picture below shows my QStarDict easily found at Kubuntu start menu, panel, and desktop.


Search A Word


On its window, type a word in English and you see list of Indonesian words displaying automatically on the fly. Try the same thing from the other side Indonesian to English. Picture below shows an example, suppose I don't know the meaning of the word distribution then I type that on QStarDict and I can see the meaning in Indonesian pemberian.


Scan On Screen


This is the coolest feature of QStarDict. 

Open an English webpage and try to double-click a word. Conversely, try it on an Indonesian webpage. To enable or disable this feature, give or remove check mark on Scan option by right-clicking QStarDict icon staying at system tray.

It can also scan document.

Yes, it can scan PDF as well.



Spell a Word with Voice


It is another cool feature of QStarDict as it can speak out loud every English word. For example, Indonesian students can learn English pronounciation word by word at home this way. Do a scan like above and click the speaker icon.


Note: if you don't hear anything, install the package festival as mentioned above.

Afterword
That's all. I hope you enjoy learning languages on computer by using QStarDict. Thank you very much Huzheng for creating StarDict the best desktop dictionary ever. Thank you Alexander for creating QStarDict its continuation. See you on the next tutorial!

Dell Ubuntu, Lenovo Fedora, and Slimbook Elementary OS

Friday 16th of October 2020 03:17:00 AM

This year good news coming one after another. Everything starts with Fedora announcing Fedora on Lenovo ThinkPad laptops, then Ubuntu announcing Dell XPS Focal Fossa, and now elementary OS announcing both Slimbook and Pine64 PineBook laptops. Now everybody globally can find Ubuntu, Fedora, and elementary OS preloaded on branded laptops and PCs. This means GNU/Linux desktop goes mainstream. I am happy to see this. I really want to sum them up in one article so everybody sees these great moment. For everyone who loves Free Software community here's the news for you!


Subscribe to UbuntuBuzz Telegram Channel to get article updates.



Dell XPS and Ubuntu

 

Following Ubuntu LTS release April this year, Canonical, the company behind Ubuntu, announces the availability of Ubuntu preloaded Dell XPS laptop. Read the official news. Visit purchase webpage.



Lenovo and Fedora

 

Following latest Fedora GNU/Linux release June this year, The Community announces the availability of Fedora Workstation preloaded Lenovo ThinkPad laptops. Read the official news. Visit purchase web page. Watch the unboxing video by Fedora leader Matthew Miller.



Slimbook and Elementary OS

 

Following latest update of elementary OS this September, and welcoming the next version 6.0, elementary OS announces a very good news that Slimbook the Apple-like European computer maker now ships their MacBook-like laptops and iMac-like workstations  with elementary OS preloaded. Personally, when I look at the picture for the first time, I think it is pretty suitable for the workstation to have elementary OS and that is exactly what I want to see for years. Read the official news.  Visit the purchase webpage Pro X laptop and Apollo workstation.


Surprise, not only Slimbook but apparently also Pine64 the ARM technology laptops and smartphones maker wants to join the retailer group and will make Pinebook laptops preloaded too. It is still in development between two parties and you with ARM knowledge can participate too before the real shipment begin. What makes Pinebook became a best seller is thanks to ARM technology used you can imagine a standard laptop but with battery efficiency and low weight of a smartphone then no wonder everyone knows wanted it. Before elementary OS, Manjaro has been successfully shipped with Pinebook and we are now wishing the real thing happens soon with elementary. However the photo is already available at elementary website and it is so appealing. Read the official news


Afterword

 

We are glad to see these good news. I agree with what Fedora Magazine said, this is really "good opportunity to grow our community" both in technology and in business. I also agree with Valentin David in his presentation at GUADEC 2020 that GNOME should be "Preinstalled on hardware", citing a GUADEC 2012 quotation, to expand our community further. That's why I see these news all are good and I want to witness more. I wish more computer models will be supported by Lenovo for Fedora, more models for Ubuntu by Dell, and soon the real things will be ready for PineBook elementary OS. Further, I expect ASUS, FUJITSU, TOSHIBA, and other vendors will also join our community to ship GNU/Linux operating systems with their computers. It would be lovely to see greater job vacancies opened thanks to these. Finally, here's my summary I hope you will like it.

How To Use AQEMU Virtual Machine on Ubuntu

Thursday 15th of October 2020 04:19:00 PM

We are fortunate to have a good virtual machine tool AQEMU on GNU/Linux operating systems. With AQEMU on your Ubuntu computer, you can virtualize any operating systems very easily. It can replace and works similarly to the proprietary tool VirtualBox or VMWare step by step as you can see in this tutorial. Now let's learn virtualization!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.

What Is Virtualization


Virtualization is running an operating system on top of other operating system. The result is two or more operating systems running at the same time. To do virtualization, people use tools like Xen, VirtualBox*, VMWare*, Fusion*, or Virtual PC*. However, GNU operating systems with Linux kernel have advanced virtualization technology named AQEMU which is a complete solution similar to VirtualBox or VMWare. In a virtualization, the OS that runs the virtual machine called host or hypervisor, while the OS that is running in that virtual machine is called guest.

*) Proprietary software.


Summary

 

To do virtualization with AQEMU you will do 5 steps:

  • 1) Creating a new virtual machine.
  • 2) Creating virtual memory.
  • 3) Creating virtual hard disk drive.
  • 4) Adding OS image.
  • 5) Run virtual machine.

 

Get AQEMU


On Ubuntu operating systems, you can get it from Software Center. Example below is AQEMU found in Discover the software center on my Kubuntu computer.


Run AQEMU


Find AQEMU blue logo on your start menu and run it.

Example above is AQEMU found on Kubuntu start menu and also appeared on desktop wallpaper area. That means AQEMU has been installed on my Kubuntu computer. The start menu has been changed into classic style and AQEMU is located under System category. Your GNU/Linux computer should lookssimilarly.


Initializing AQEMU


Before anything, when you first launch AQEMU, you should do the initial setup. It asks you two things which are first create a hidden directory for everything, and second find the actual QEMU installed program on your system. Important: it is better to choose directory path in the largest free space disk drive you have as virtual hard disk files will be stored in this directory by default.


  1. By default, AQEMU displays a .aqemu folder path which is located in your home directory. In this example I let it be the default which is located in my home directory in my 20 GB filesystem disk drive. Click Next.

  2. It asks for where the QEMU program is exactly located in your computer. Click Search button and it will instantly find them. For example, in my Kubuntu they are located in two folders /usr/bin/ and /bin.

  3. It shows “finished” message. That means everything is okay and now you are ready to do virtualization.

  4. Successful AQEMU initial setup will look like picture above. It is AQEMU window with all buttons and an empty virtual machine list with all tabs displayed vertically.


1. Creating a Virtual Machine


First thing to do is creating a virtual computer or also known as a virtual machine.


  1. Go to menubar VM > Add VM > Add New VM > first page showing choices > select Typical > go Next.

  2. By default, AQEMU supports four different operating systems which are GNU/Linux, FreeBSD, Windows, and MacOS plus ability to generate your own support for another OS if you wish. Because this tutorial wants to virtualize Trisquel which is GNU/Linux, we will select Linux 2.6 template. On this second page, select Template > select Linux 2.6 > go next.

  3. On the third page, select KVM > go next. If you cannot select KVM here, enable Intel-VT or AMD-V virtualization feature on your BIOS and try again.

  4. On fourth page, give name to your virtual machine. Name it gnu. Go next.

  5. On fifth page, determine how much virtual hard disk size for your virtual machine. Normally GNU/Linux desktops are fine with just 20 GB. This hard disk is represented as file by size you chose in your computer hard disk drive. Go next.

  6. On sixth page, so that your guest OS can connect to the internet, select User Mode Network and go next.

  7. Finished everything on seventh page. Now click Finish.

  8. AQEMU with one virtual machine created will look like this. Pay attention to the five tabs presented vertically [Info] [VM] [Media] [Display] [Network].


2. Creating Virtual Memory


Second thing to do is determining how much memory for your virtual machine taken from your real computer memory. Select your VM name gnu > open the tab [VM] > set the memory to 1500 MB > Apply. 


By making virtual memory, your computer will share several GB memory for host and several GB other for guest. Bigger memory size means more applications to run on the guest but also fewer task can do on the host. For virtualizing modern operating systems like Ubuntu Desktop and Microsoft Windows, today >=1.5 GigaByte or 1500 MegaBytes virtual memory is good. For lightweight and old operating systems like Lubuntu or Windows 98, half gigabyte or >=512 MegaByte is enough. For example, as I want to run Trisquel 9 Etiona which runs well under 1GB memory, I determine here 1.5 GB for virtual machine so my host computer still has the rest 2.5 GB.


3. Creating Virtual Hard Disk


Thirdthing to do is creating a new virtual hard disk. Imagine this as hard disk drive where you install the operating system into. If you already made your virtual hard disk in previous step, skip this. If you want to change or move it to another disk partition, do this. 


  1. First thing is to see whether your VM has a virtual hard disk or not. Select your VM name from the list > open the tab [Media] > your virtual hard disk should exists there with the name HDA (/path/to/file). If it does not exist, or if you want to change it, go to next step. If you see everything is OK, skip this section and go to next section.

  2. To create new one, select existing HDA > click Manage Devices Properties (pen on paper button) > Properties dialog appears > click Create (green plus button) > Create dialog appears > click Browse > name the virtual disk image file > place the image file in computer disk drive with most free space > OK > select Format: qcow2 > determine size 20 GB > click Create. For example, I placed my file in my data partition New Volume (/media/master/New Volume/gnu-virtual-hard-disk-drive.img).

  3. A dialog appears informing that the virtual hard disk drive creation was created successfully.

  4. You went back to Properties dialog. Here you see your virtual hard disk drive image file is correctly located in the path you have created. In my example, it is /media/master/New Volume/gnu-virtual-hard-disk-drive.img. Close Properties dialog.

  5. AQEMU with a virtual hard disk drive set properly.


4. Adding OS Image


This is where you insert operating system image file you desire. For example, here I insert Trisquel GNU/Linux. The file extension is .iso by size 1.7GiB and my Kubuntu categorized it as raw CD image as you can see below.

  1. Make sure you know where you store the OS image file. For example, my Trisquel image by 1.7GiB size is stored in Downloads folder in my home directory.

  2. Go back to [Media] tab > click Add Devices CD (CD button) > Properties dialog appears > click folder button > Open File dialog appears > browse and find the image file > select the image file > Open > you went back to Properties dialog > OK.

  3. AQEMU with a virtual hard disk drive and an ISO image file means ready to run virtualization.


5. Running Virtual Machine


Select your VM name > go to menubar VM > Start (Ctrl+S). Now you should see the operating system runs. This results in two operating systems running where one as host and another one as guest. In this example, my Kubuntu is the hostwhere my Trisquel is the guest. This is the stage where you start the fun. You can install the operating system or simply preview it (LiveCD). For Windows and macOS and alike they can only be installed and cannot be previewed. But for GNU/Linux OSes they can be installed as well as previewed (LiveCD) and my Trisquel is one.



6. Stop Virtual Machine


To stop virtual machine, go to virtual machine window menu bar Machine> Power Down. To restart, select Resetinstead of Power Down. Alternatively, inside the virtual machine simply use Shutdown or Restart button available on the operating system. It is just like real computer, you can rebootor shutdown it.

 

Afterword


That’s all with AQEMU use basics. Thisdoesn’t give you more techniques like USB connectivity or advanced ones like networking but I wish it’s enough for beginners to start their virtualization life. By making this article I want people to recognize the free software AQEMU as the alternative to the proprietary VMWare or the – unfortunately– currently nonfree VirtualBox. 

 

My Lenovo ThinkPad and Ubuntu

Wednesday 14th of October 2020 03:55:00 PM
At Saturday 10 October 2020 finally I purchased Lenovo ThinkPadthat I wanted for a long time. It replaces my old laptops Asus and Acer which are already unusable for all my works especially here at Ubuntu Buzz. Now I have a decent computer to write Ubuntu articles I love here. As an avid Ubuntu user, of course I tested it immediately with 20.04 and it made me so happy everything runs faster and better. I feel it is perfect. It is a T430 from 2012 with Intel Core i5 and four GB memory and 320 GB hard disk drive plus its trademark red trackpad and everything else. I found it new by price Rp2,5 millions or roughly $169 so I think I’m lucky. I now can recommend ThinkPad to everyone especially those who want laptop to run GNU/Linux and Free Software. To share my happiness with you, below I listed details of my ThinkPad with important notes.

My Thinkpad Summary


It is dream comes true laptop to me. Its design looks cool. It works perfectly with latest Ubuntu and Kubuntu LTS. It works very well with latest Trisquel Etiona too but the wifi does not work along with the bluetooth. The display is just like what I want a fine non shining one so now I can photograph my display just fine. The important part is my ThinkPad does not have NVIDIA Geforce nor ATi Radeon which makes me very happy I feel free from troubles. It lasts for 3.5 hours according to my test at its first days which is very good for me.


Specification


  • Processor: Intel Core i5
  • Memory: 4GB
  • Hard disk drive: 320GB
  • Video card: Intel HD Graphics 4000
  • Booting firmware: UEFI and BIOS Legacy 
  • Ethernet: Intel Gigabit

How To Install Ubuntu With ‘D Drive’-like Data Partition

Monday 12th of October 2020 03:18:00 PM

Actually it is very easy to install Ubuntu alike operating systems with data storage partitions similar to Drive D: to mimic tradition of Windows computers. What you need to do is just install Ubuntu like usual but create one additional large partition without attaching mount point to it. The result is you will always see one data partition ready to use just like you usually found while using Windows. Just because apparently many people asked it then I make this tutorial to help. As stated it is for Ubuntu alike, you can also practice this to Fedora, openSUSE, Manjaro, and others.

 (A Kubuntu laptop with New Volume displayed as data partition)

Preparations


Prepare separate disk partitions. Don’t just create system partitions, but also create data partitions. This kind of setup is actually what traditionally Windows Computers are where C is for system and D is for data.


Installation


Do operating system installation like normally we do it. But the only difference is let the data partition without mount point. If you don't know how, here are installation guide examples which includes explanation on dualboot and uefi modes:

 

Finish


Finish the installation like usual. Nothing special.


Result


Once you run your Ubuntu computer you will have data partition ready to use. Happy working!

Fix Failed To Fetch When Updating Trisquel Flidas

Saturday 10th of October 2020 05:13:00 AM

You may find you cannot update your Trisquel 8 computer. In my case, the issue is after about one year have not been used, today I run my Trisquel and I am unable to get more applications. For such issue, In most cases, the solution is to change your software sources and try updating once again. Below is how to fix it.

Subscribe to UbuntuBuzz Telegram Channel to get article updates.

Error Messages


Here is the error message you may encounter:

W: Failed to fetch [URL] Unable to connect to [URL]
W: Some index files failed to download. They have been ignord, or old ones used instead.

Picture below shows the error my computer experiencing:

Cause


In my case, it is caused by my repository is no longer working anymore. Inactive repository makes your Trisquel computer unable to get software and updates resulting to error above.  (To my inactive repository''s maintainers in India I say my gratitude and respect you gave me greatest things ever on computing.)

Fix


Change your download source from the inactive one to an active one. To do so, open Software & Sources > click the Download from button > click Select Best Server > wait for a while > finally pick the one that selected automatically by the computer. For example, in my case as I live in Indonesia, computer picked me the United States one as the fastest for me. See picture below.

Then simply do a reload or $ sudo apt-get update command line. Fixed Trisquel computer in this case should shows normal output lines without error message above like picture below. You can even see download speed, size, and time.

Proof

 

Test it! Try to install a new application. In my computer, I tried to install KeePassX a nice password manager and it works successfully. You can do it either by Synaptic Package Manager or command line $ sudo apt-get install keepassx .

Have a nice day!

Save Webpages You Care About to Archive.org

Wednesday 7th of October 2020 04:34:00 PM

Archive.org is the time machine of the internet. You can find on it any web page ever published since 1996. Think Google but you can go back to any point in history of every result. You can also be part of the time machine or contributing to it. This article invites you to try The Internet Archive and contribute by saving pages you love to be a history everyone can read. Believe me it is fun!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.What Is Archive.org? 

Go to www.archive.org it is the Internet Archive. It currently holds 400 billions web pages according to Wikipedia as well as three millions movies, four hundreds thousands of computer programs, and seven millions audio files. Yes Internet Archive is not only a search engine, but also a giant storage of digital files. The point in this article is that Wayback Machine, the time machine within Internet Archive, can bring us back to a point in history for any web page ever published. That means it can reveal dead websites too. You can imagine how much benefits you can get from using it correctly, say, for historical or even crime proving purposes.


Wikipedia Uses Archive.org 

Ever read Wikipedia's references? You might saw links that followed by words "archived from the original" and if you follow the link you'll find the web page in a point in history. If you look closer, actually archived web pages there are in the Internet Archive. Check for example references on Ubuntu. That's an excellent example how Internet Archive benefits us.

Searching

 

Type the address of website you like in www.archive.org. Then you will see history of that website saved within Internet Archive. For example, if you enter the address ubuntu.com you can see history of Ubuntu website from time to time since first introduction 2004. Try other websites too!

1) Go to Internet Archive

2) Search for ubuntu.com like below. This is an example. You can type any other web URL address.

3) You see full history of ubuntu.com web page shown as a calendar. There are blue and green bubbles showing when the time Internet Archive saved them.



4) Pick one history point available among the colored bubbles. You can also see the Internet Archive's URL address of that page. Feels familiar? Yes, it is how Wikipedia gets its archived references.

5) You see ubuntu.com website in that point of history. Here is Ubuntu website in 2006 as is without any alteration saved perfectly by Internet Archive.

Quick Search

 

You can do searching above without visiting archive.org. Visit a website and click the button to see its history or last archived instantly from the Internet Archive. Very convenient, right? See last section to get that button on your web browser.


Is A Web Page Archived?

You can see whether a webpage you visit is already archived or not. Also, you can see whether the archive is up to date. Later on, you can contribute to the internet history by helping save web pages to Internet Archive! To check a web page, click the button and let it loads a bit to see last archived date.


Saving


Everyone can archive webpages to the Internet Archive! Visit a webpage and click Archive Page button and it archived instantly. As a result, now everybody can visit the webpage's history on the Internet Archive. You can share the URL address to your friends. You can repeat this process to any other web page. Pretty interesting, right?


The Button 

Actually it is an addon called Save To The Wayback Machine. that can be installed to Mozilla Firefox. Go to the addon page and click install there and voila you got the button we discuss above. Following picture is the screenshot of addons installed on my web browser and the emphasized one is the Save To. That's all. Finally, I hope you find fun learning internet history!

Happy archiving!

What To Do When Your Computer Fails

Tuesday 6th of October 2020 02:39:00 PM
This is a note I took based on my experience with computer failure. You can imagine worst situation when everything is closer to an end. It feels frustrating and can lead to despair. You may already found the signs that your hard disk drive, display, touchpad, USB ports, are already in worse condition. Before your machine die for sure, you can learn something from my reflections below as now mine died. It died after worked for me since 2016 almost nonstop everyday. I hope you would never experience any of my story and only got solutions and the good things if anytime things going worse.

Subscribe to UbuntuBuzz Telegram Channel to get article updates.
Keep Your Mind Calm
From freedom came elegance. From calm came reasons. From patience came solutions. When I got a trouble I keep talking to myself to calm. Only calm mind can solve a thing. Anger or despair alone cannot. I do not have particular attachments to slogans but GNU/Linux Mint’s slogan came first while I writing this so I put it here and thank you Clement Lefebvre!
Purchase A Capable Computer
First thing is to have a good computer. This is a thing we should do far before everything. A good one is a durable, tested, well acknowledged by capable people. I know I admire Purism Librem laptops until I think to have one, as well as System76’s and Entroware’s but they are expensive to me for now (with respects to them). For my next life, personally I wish I could buy Lenovo Thinkpad for sure as a replacement to the broken one. For a long time I learn about Software Freedom it is Thinkpad that is often praised by activists, and even more awesome than that, all certified laptops by Free Software Foundation in their Respects You Freedom are Thinkpad. I wish that for not only the hardware quality but also the best compatibility to GNU/Linux operating systems compared to other brands. Currently I see either the T430 or the X200 family is desirable. With a good computer you will find good life just any other people for decades long.
Backup
The failed part of my computer is hard disk drive. The problem is that all my data is there and no backup. I regret I didn’t do backup. My excuse is reasonable as I do not have external storage to store copies of files I have as they are gigantic. If only I had a spare external disk drive, I would had them all backed up right away. For my next life, I think I should encrypt all my data in a compressed archive and upload them anyway to online storage (perhaps multiple of them) I trust.
Fix Charger, Don’t Overcharge, Don’t Undercharge
This is electricity trouble. It was already a solved issue for me but when I got this trouble it was devastating. I could not work at all. I could not teach either. If you ever find anomaly with your charger, buy a new one correctly (expensive) or go to an electro technician to fix it up (cheap). I did the latter and it was really a solution. If you live with batteriess, don’t overcharge and don’t undercharge either. Overcharge by keep charging even though battery is full. Undercharge by keep using computer until it runs out of power without shutdown. Overcharge is bad to your battery. Undercharge is bad for your hard disk drive and your data.
 Use Non Journaling Filesystem
I believe I must use ext II for my next hard disk drives and not ext IV. I am a person who do not need much technology so even old one but works well (and prolongs my disk drive lifespan) will sufficient to me rather than the new ones that not. I am not interested in butterfly or cow. You cannot save anything if the hardware itself fails. I work heavily (much more heavier than average people) in data so filesystem that writes less is better than filesystem that writes more. Ah, and, actually my hard disk drive mentioned above is a solid state disk. I already used this trick for my SanDisk usb flash drives as I do not have spare storage I use them instead as places to install operating systems I was reviewing and as I said they work very well. 
Do Not Throw Away Components
Before this case, I already had another broken laptop, my first one. Fortunately I didn’t trash it. It is Asus X44C but it has a component worth keeping that is Atheros wifi compatible to Trisquel. It is truly a blessing. It means I can swap it (“cannibal”) to another laptop and I can run any of all GNU/Linux distros works with the wifi out of the box without worries. There are some possibilities other componets still worth keeping too, say, the LCD monitor can be sold with good price. 
Don’t Overheat
Heat kills. Overheat can destroy your hardware. I believe one of the causes of my hard disk drive failing is heat as Indonesia got very hot lately at noon and in fact this computer is already old. I do have a small usb fan but I don’t use it often as the cable is too short and my touchpad is unusable. For my next life, I plan to purchase a decent usb fan worthy for my laptop.
Don’t Use Failing Dongles
I have a reliable usb wifi I used for years. I like it. It was truly convenient. Unfortunately around the rising of Corona it showed anomaly so bad it made every of all operating systems I use (GNU/Linux) need to be forced shutdown. The worst, it occured very often randomly without predictable pattern and when it occured I always couldn’t do reboot or even reisub to save health of my hard disk drive. Since I removed it such problem never occurs again. I believe it was caused by either hardware bug or some physical failure. If you have failing dongle like that, stop using it, replace it with a new one if you can.
Buy Keyboard Immediately
If your keyboard shows signs of breakage, replace it right away. No matter whether you are an author like me, online teacher, programmer, designer, government worker, or simply computer user, your keyboard is your computing life. It is not a problem in my current case, but I had experienced broken ones three times, and every time it was disaster. Trust me it is counter-productive.
Bubble Wraps
It is a good idea to layer the inner parts of laptop bag with bubble wraps. Bubble wraps are shockbreakers. No matter it is ssd or hdd inside, your laptop deserves safety from shocks and bubble wraps can help and they are very cheap. Use some simple adhesive tapes to install them.

Summary
It is good to have good computer since the beginning. Whenever a hard disk starts failing, do not wait to backup. Whenever we can afford to buy good computer or replacing peripherals, do it immediately. Finally, I wish you all good computing life!

What To Do After Installing Kubuntu Focal Fossa

Sunday 4th of October 2020 10:20:00 AM
This is the traditional suggestions list for everyone having new computer with Kubuntu operating system. It is intended for version 20.04 LTS Focal Fossa right now. This includes tips and tricks about adjusting your battery management, desktop conveniences, apps recommendation, and more. I wish you enjoy friendly computing with Kubuntu by reading this. Let's go!
Subscribe to UbuntuBuzz Telegram Channel to get article updates.
Summary
    1. Battery Power
    2. ClassicMenu
    3. Clock
    4. Icons on desktop
    5. Don't group apps!
    6. Ad blocker + security + privacy
    7. KeePassXC
    8. Reload
    9. App Hunting
    10. Find Friends & Learn More

    Power saving
    Special for laptop users! To prolong your battery power duration, Kubuntu has excellent configuration under System Settings. You can do many things to reduce power consumption (hence comes power saving) and also decide what to do when the laptop experiences low battery (to avoid disk drive failure). To do so, go to System Settings > Power Management > On Battery > reduce screen brightness > reduce dim screen time delay > reduce suspend session wait time > Apply. To enhance it, still on the same dialog, go to Advanced Settings under Energy Saving > set low level a little bit higher e.g. 20% > set critical level also a little bit higher e.g. 10% and set action At critical level: Shutdown instead > OK.
    Clock
    You can switch Kubuntu's clock to show all details up to weekday and second. Personally I like it as it helps making my screenshots clear about when exactly I took them. To do so, select Configure Digital Clock by right-clicking it > Appearance > give check marks to Show date - Show seconds - Show local time zone > select Date format: Long Date > OK.

    Classic style menu
    Default start menu style is called 'Application Launcher'. Unlike the classic style called 'Application Menu', it cannot show many apps simply. To switch back to it, select Show Alternatives by right-clicking the start menu button > Application Menu > click Switch > you got Vista-like style start menu.

    Icons on desktop
    I like Kubuntu as it allows icons on desktop. You can put apps, documents, videos, ebooks on the wallpaper area like any professional OS can (even Android can!). To do so, open your start menu > drag one app > drop it on the desktop > select Link Here > voila! To do files or documents, the procedures are just the same unless you do it from Dolphin File Manager instead of start menu. 
    Following picture shows I can put favorite apps such as LibreOffice and Discover along with my frequently accessed folder Downloads and a pdf of Kubuntu User Manual.
    Have password manager
    Today every computer user should have a password manager. It helps us keep safely passwords, accounts, and secrets without us remember any of them. We just need to remember one master password, that is, to open the application to access everything kept within it. Install KeePassXC from Discover and learn here to use it.


    Don't group apps
    Kubuntu groups running apps on its panel.  This default behavior is not comfortable, as it makes the user works more just to switch to a window they want. You can switch back to no grouping. To do so, select Configure Task Manager by right-clicking a running app > More Actions and then on the appearing dialog select Behavior > switch to Do not group under Group: option > OK.


    Ad blocker and Security plus privacy
    As usual, taking care of your web browser is among the first things you need to do after having new system. Here once again I recommend three magics Startpage.com (privacy alternative to Google), uBlock Origin (to block ads and trackers), HTTPS Everywhere (security enforcer) you can install on Mozilla Firefox by going to addons.mozilla.org webpage. Read more about internet privacy at PrivacyToolsIO and also PRISMBreakOrg.
    Reload your repositoryUnlike Windows, Kubuntu works with repository – users get apps from a central place in the internet. So that you can grab more apps and get notified of new updates, reload your repository. Open Discover (the blue bag logo) and keep your internet access up for a while it will automatically do it for you. When you see yellow sign on bottom-left, it means your repository has been reloaded and you are ready. If you prefer doing it by terminal, it's fine, invoke the command line sudo apt-get update and let it go.
    Hunt applications 
    The purpose of operating system is for user to have apps. So is Kubuntu. Discover is there for you to discover tens of thousands of Free Software application for any purpose you can think and imagine. Video games, multimedia editors, programming tools, everything is prepared beforehand you can access easily here.

    Find Friends
    Official support community is kubuntuforums.net. Telegram community is also available at t.me/kubuntu_support. Internet Relay Chat (IRC) room is accessible via web or if you prefer using IRC client go to #kubuntu at Freenode.  
    Learn more
    Fortunately, Kubuntu Project provides us with excellent documentation we can read and download. Commercial support is available here for instance when you are a company just migrated from Microsoft Windows. The big clue is everything for Ubuntu is applicable to Kubuntu too. Finally, go to Ubuntu Official Help as recommended by Kubuntu website itself to learn more. 
    I wish you like it!

    How To Use KeePassXC Password Manager

    Saturday 3rd of October 2020 02:34:00 PM
    As I have stated many times in this blog, having password manager application is important for everyone using computer nowadays. Now it is a simple tutorial to begin using KeePassXC, a libre software to keep your passwords, identities, and secrets safely so that can access them all by a single master password only you know whenever you forget. Thanks to this app we can make passwords as secure as we want without the burden to remember any of them. Now let's start learning!Subscribe to UbuntuBuzz Telegram Channel to get article updates.
    Get KeePassXC
    Note: KeePassXC as appimage is a portable version for GNU/Linux you can learn here to run it. For Android, it is 'KeePassDX' a mobile app which is compatible with but not developed by KeePassXC.
    Objective
    Final results should look like my password manager below. 
    With this, I keep many online accounts in it safely I can look into at any time so the good news is I do not need to remember any of them anymore.
    First Step
    In the beginning, you create a new database with a password you decide. That is master password. Nobody can access passwords you store unless you who know the master password. After making one, exit the app.
    • 1) Create a new database and continue.
    • 2) Give the database name as you wish and continue.
    • 3) Let the encryption options as is and continue.
    • 4) Type master password you wish and repeat same password under it and continue.
    • 5) Save the database file (.kdbx) in a nearby folder for example ~/Documents and finish.
     Open and Close The App
    To make you accustomed to it, first, run the app and then, enter your master password. Now you see it is empty means ready for you to fill it. Instructions below are examples easy for you to follow to start keeping your credentials here.
    Store Your Secret
    • Username: life@gmail.com
    • Password: 1234567890
    Suppose one account you have consisted of pair above. Then for example you make new entry like these in the app:
    • 1) Go to menu Entries > New
    • 2) Fill Title: My Gmail Account
    • 3) Fill Username: life@gmail.com
    • 4) Fill Password: 1234567890
    • 5) Repeat Password: 1234567890
    • 6) Fill URL: www.gmail.com
    • 7) Click OK

    Look A Password
    Suppose you forgot one password. Suppose it is Gmail's. To see the password you kept, open the app and enter the master password and select the entry (Gmail here) and go to menu Entries > Edit  and click the eye button to see the password and click it again to hide it.Useful Tips
    • Don't let anyone know your master password.
    • Make sure you never lose your database file e.g. Passwords.kdbx as you can make backup of it to external storages.
    • Use Notes section in every entry to write down important information such as terms of service, sale discounts, or anything else.
    • Go to menu Database > Recent to access your latest opened database.

    Enjoy!

    Enjoy YouTube Without YouTube

    Thursday 1st of October 2020 12:40:00 PM
    Enjoying YouTube without YouTube means you can watch and download all videos from it everywhere by alternative ways so that you don't run nonfree software or surrender your privacy. There are good news I want to share with you as there are already Invidious and CloudTube for computer users while NewPipe for phone users. They are all free libre open source software developed by community you can trust. I am happy with these solution so I want you to share my happiness as well. Enjoy!
    FreeTube - a desktop app to enjoy youtube comfortably
    Subscribe to UbuntuBuzz Telegram Channel to get article updates.Background
    Since few years ago I stopped going to youtube.com as per I read the amazing essay JavaScript Trap and then I found Invidious from Trisquel Forum discussions. Thanks to Invidious, I can continue watching videos from youtube without going to youtube.com for years. I felt this is really a solution. That means I save my computing from nonfree javascript and at same time my online privacy plus I have ability to download the videos. I believe people will also love that. However, sadly September this year Invidious discontinued. The issue is videos I usually watch normally now cannot play in Invidious. The cause is that Google the owner of YouTube changes how users and software can access YouTube videos and eventually block ones they do not like. That's why making solution in this case is a hard job because the developer must update their software following YouTube's blocking otherwise the solution will not play any video. When I was looking for alternatives lately, I found CloudTube and NewPipe, then I immediately got nice experiences to share with you about them.
    For Ubuntu Computer
    InvidiousInvidious: this Omarroth's artwork is the beginning of all. By going to the website www.invidio.us we can watch and download youtube videos free from ads, proprietary javascript, and online tracking. Now it is discontinued, but there is still hope, as we can still continue watching by going to alternative instances say snopyta.org.
    CloudTubeCloudTube: fortunately, here is CloudTube a new Invidious-like web that lets us to watch youtube videos free from ads, javascript, and tracking. You go to CloudTube website and simply search and play any video. Currently it is still in active development at Sourcehut and written in Python the most popular programming language according to StackOverflow to attract more developers.
    FreeTube: finally, it is a decent desktop client everyone can use. It is like Invidious, and even more like YouTube app on Android, but you can run it as an app on computer to watch and download videos. Download it as AppImage and run it on Ubuntu. FreeTube is a serious software project that available for three major operating systems GNU/Linux, Windows, and macOS. When I encounter FreeTube once again, I felt it is very similar to NewPipe on Android. It is still in beta version but it works already you can try.  (FreeTube app runs on my Kubuntu laptop as portable application with several popular channels subscribed and cool videos displayed)
    Worth mentioning: MiniTube, Youtube-dl, PeerTube
    For Android Phone
    As many Ubuntu users have Android phone as well, here is a bonus for you all. I always recommend install apps from F-Droid instead of Play Store for it is better software center, completely free and secure, for Android.
    NewPipe: I think it is cool. It is the mobile YouTube player that is very convenient. It features search, watch, download, pause / resume, audio-only, quality options, subscribe, playlist, customizations, and many more. You will find it even better than the flagship proprietary YouTube app. Download it from F-Droid.
    (NewPipe: from left to right: searching for videos - displaying a video - playing it)
    Summary
    Let's continue to watch YouTube videos conveniently. I wish Invidious and CloudTube projects continue well. I wish this article introduces NewPipe well to the vast Android users too. Last but not least, I wish PeerTube will be mature enough soon so we will experience even more convenient video platform. For those who interested, feel free to read our previous articles regarding these:

    Enjoy!

    • Arduino Blog » Driving a mini RC bumper car with a Nintendo Wii Balance Board

      Taking inspiration from Colin Furze’s 600cc bumper car constructed a few years ago, Henry Forsyth decided to build his own RC miniature version. His device features a 3D-printed and nicely-painted body, along with a laser-cut chassis that holds the electrical components. The vehicle is driven by a single gearmotor and a pair of 3D-printed wheels, with another caster-style wheel that’s turned left and right by a servo steering. An Arduino Uno and Bluetooth shield are used for overall control with a motor driver. The Bluetooth functionality allows for user interface via a PS4 controller, or even (after a bit of programming) a Wii Balance Board. In the end, the PS4 remote seems to be the better control option, but who knows where else this type of balance technique could be employed?

    • Introduction to Ironic

      The sheer number of projects and problem domains covered by OpenStack was overwhelming. I never learned several of the other projects under the big tent.

    • Secure NTP with NTS

      Many computers use the Network Time Protocol (NTP) to synchronize their system clocks over the internet. NTP is one of the few unsecured internet protocols still in common use. An attacker that can observe network traffic between a client and server can feed the client with bogus data and, depending on the client’s implementation and configuration, force it to set its system clock to any time and date. Some programs and services might not work if the client’s system clock is not accurate. For example, a web browser will not work correctly if the web servers’ certificates appear to be expired according to the client’s system clock. Use Network Time Security (NTS) to secure NTP. Fedora 331 is the first Fedora release to support NTS. NTS is a new authentication mechanism for NTP. It enables clients to verify that the packets they receive from the server have not been modified while in transit. The only thing an attacker can do when NTS is enabled is drop or delay packets. See RFC8915 for further details about NTS. NTP can be secured well with symmetric keys. Unfortunately, the server has to have a different key for each client and the keys have to be securely distributed. That might be practical with a private server on a local network, but it does not scale to a public server with millions of clients. NTS includes a Key Establishment (NTS-KE) protocol that automatically creates the encryption keys used between the server and its clients. It uses Transport Layer Security (TLS) on TCP port 4460. It is designed to scale to very large numbers of clients with a minimal impact on accuracy. The server does not need to keep any client-specific state. It provides clients with cookies, which are encrypted and contain the keys needed to authenticate the NTP packets. Privacy is one of the goals of NTS. The client gets a new cookie with each server response, so it doesn’t have to reuse cookies. This prevents passive observers from tracking clients migrating between networks.

    • Hetzner build machine

      This is part of a series of posts on compiling a custom version of Qt5 in order to develop for both amd64 and a Raspberry Pi. Building Qt5 takes a long time.

I ended up setting up scripts to automatically provision a throwaway cloud server at Hetzner.
