Installing LibreOffice 7.0 on Ubuntu 20.04 LTS

Wednesday 12th of August 2020 04:25:00 PM
We're happy LibreOffice 7.0 finally released early August this year. This tutorial explains things for you wanting to get it on Ubuntu 20.04 LTS Focal Fossa. This tutorial offers you standard ways (Deb) as well as alternative ways (AppImage, Flatpak, Snap) you may choose to install it. For merely testing purpose you must start with the AppImage one as it is safest to your system. Finally, congratulations to LibreOffice community and gratitude to all the developers! Happy writing!

Deb
This is the standard way to install LibreOffice on Ubuntu. If you install it this way, your previously installed LibreOffice will be removed and replaced with the version 7.0 one.
  • Go to https://libreoffice.org/download/download.
  • There is a notice "Download LibreOffice 7".
  • Choose your operating system on the selection "Linux (64-bit) (DEB)".
  • Click "Download" button. 
  • You got a file named "LibreOffice_7.0.0_Linux_x86-64_deb.tar.gz".
  • Extract the file.
  • You got a folder named "LibreOffice_7.0.0_Linux_x86-64_deb/".
  • Find within that folder a folder named "DEBS".
  • You got a bunch of files which names ended with ".deb".
  • Open in Terminal by right-click within this folder.
  • Do installation command.
  • Wait the process.
  • Finished.
  • You successfully installed LibreOffice 7.0. 




Snap
Not available yet at the moment.

This is a new way to install software on Ubuntu. This will not replace your originally installed LibreOffice.

Flatpak
This is a new way to install software on Ubuntu similar to Snap. This will not replace your originally installed LibreOffice.

  • Run first flatpak installation to your system[1].
  • Run flatpak command[2] to connect to the software repository. 
  • Run flatpak command[3] to install LibreOffice 7.0.
  • Finished. 
  • Successfully installed.
  • Run LibreOffice Flatpak[4].

[1]
$ sudo apt-get install flatpak[2]
$ flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo[3]
$ flatpak install flathub org.libreoffice.LibreOffice
    [4]
    $ flatpak run org.libreoffice.LibreOffice
    AppImage
    This is the universal and quickest way to install software on GNU/Linux. This way is similar to Windows's user's way to get EXE applications and so does MacOS's user's DMGs. This will not replace your originally installed LibreOffice.
    • Go to AppImage download page.
    • You see a notice "LibreOffice as Appimage".
    • See More Downloads, go to Stable page, Basic section, find the LibreOffice 7.0 choice.
    • Download LibreOffice-7.0.0-x86_64.AppImage
    • You got LibreOffice 7.0 AppImage file by 200MB size.
    • Give executable permission to it.
    • Run it. Watch one minute video below.

    About LibreOffice

        Converting with GIMP

        Friday 31st of July 2020 11:55:00 AM
        In this tutorial you will learn to change format of photos with computer program GIMP. This means you can transform a picture from any format to JPEG, PNG, PSD, TIFF, BMP and many more. This includes making color photo into black and white too. Just like before, this tutorial also accompanied by a one minute video practicing it. Finally so you won't forget it, this tutorial is part of the GIMP for Authors the series. Enjoy editing!

        Subscribe to UbuntuBuzz Telegram Channel to get article updates directly.
        Formats
        Digital pictures are stored in computers and cameras with certain formats namely
        • JPEG .jpg .jpeg - the most popular format, excels in storage size, doesn't support transparency.
        • PNG .png - second most popular format, excels in quality, supports transparency.
        • GIF .gif - Graphic Interchange Format, animated picture, can also used in still picture.
        • BMP .bmp - Microsoft Windows Bitmap, you may want to produce a bmp to make something in Windows or involved in game making.
        • ICO .ico - Microsoft Windows icon file, you found as disk drives logos and websites favicons.
        • PSD .psd - Adobe Photoshop native format file, 
        • XCF .xcf - GIMP native format file.
        • and read here for more.

        (Same picture converted into several different formats: notice the file size between the original JPG and BMP, GIF, PNG, PSD, and XCF)
        GIMP and Formats
        GIMP can handle raster, vector, and container image formats. Its native file format is XCF. Mainly as raster editor, it can handle so many raster formats explained here and also support more rare formats by plugins. It can also read vector image format SVG and further export them to raster images. It also can read and write Adobe Photoshop native image format PSD.

        Download Examples
        Here are original and converted photos you can download to practice yourself.

        (This photo is a wallpaper in Zorin OS by Jeremy Bishop stored in /usr/share/backgrounds)
        Converting
        • Open any picture.
        • Go to menubar File > Export (Ctrl+Shift+E) > Export dialog appears.
        • Select destination folder.
        • Type the desired extension after the picture file name such as photo.png or photo.gif.
        • Click Export.
        • An additional dialog may appears to give you further settings such as compression and quality. Accept it anyway. 
        • Picture exported in the destination folder.
         (Exporting – this is how we convert a photo from one format to another) 
        Convert to XCF
        Filename format is .xcf. This is the native format and can always be opened in GIMP.
        Convert to PSD
        Filename format is .psd. This can be opened later in Adobe Photoshop.

        Convert to PNG
        Filename format is .png. Generally big in size, this can be opened in any picture viewer.

        Convert to JPEG
        Filename format is either .jpg or .jpeg. Usually any picture file size goes smaller if converted to this format.

        Convert to GIF
        Filename format is .gif. This can be opened in any picture viewer and displayed on websites.

        Convert to Grayscale
        For any color photo for any format, go to menubar Image > Mode > Grayscale > photo turned into black and white.

        Censoring
        As one minute video above shown, here is how to do it procedurally:
        • Select an area you wish to be censored using select tool.
        • Go to menubar Filters > Blur > Pixelize > OK.
        • Repeat censoring by pressing Ctrl+F to make censored area more unclear.
        • Unselect by pressing Ctrl+Shift+A.
        • Export.
         
        Examples
        Here are examples of doing censorship to general pictures and to text. Think of Zorin screenshots below as generic photos – colorful, natural, not rigid – and think of email screenshots below as text documents – complicated, boring, rigid –. The former appears in the one minute video above.

        Before:


        After:



        Before:
         

        After:

        (Notice my email address on top and sender's email addresses on middle are all censored)

        Exercises
        Continuing the previous exercises, now do these ones to improve your censoring:
        • Censor your friend's faces. 
        • Take screenshot of your own Gmail inbox and censor the mails.
        • Take screenshot of your Saved Logins in Mozilla Firefox with all password displayed and censor the passwords.
        • Take screenshot of your ifconfig output and censor the MAC addresses.

        Power - Part II of Ubuntu 20.04 LTS Review

        Thursday 16th of July 2020 09:13:00 AM
        Ubuntu is an operating system that
          does not require installation to run,
          neither activation,
          neither drivers CD for vga and wifi,
          neither antivirus.

          Previously the first part talked about Panorama - the appearance overview of past and current Ubuntu. Now this second part will talk about Power - the technical aspects "how it works" of Ubuntu most notably the installation and add/remove applications and configurations. Briefly, Ubuntu Desktop now transformed into more a mobile alike system similar to Android or iOS. Here you will find the one gigabyte memory load this version, how much the app installations changed, and things important about Ubuntu. Enjoy!

          Subscribe to UbuntuBuzz Telegram Channel to get article updates directly.< Preamble | Part I | Part II | Part III >< Download Links | Install Guide | Afterinstall | Basics | Unity | Education >

            1. Installation and Performance
            Installation & performance: on Hardy, Ubuntu size was under a compact disc capacity and required twice memory size swap partition. Now on Focal, Ubuntu is unfit unless in a dvd capacity and leaves the old swap formula. At first boot after freshly installed, Focal takes 1GiB of ram in my specification. Compare this to three hundred megabytes with Hardy.

            (Installation process of Ubuntu 20.04 LTS - showing one slide among slides that says 'An Operating System Available to Everyone, Developed for Anyone that will Just Work for Anything You Need' including the slogan)

             (One gigabyte RAM more or less to run Focal Fossa and noticeably high CPU percentage at first few minutes depicted in [Pic. 1] [Pic. 2] [Pic. 3] and see Hardy [Pic. 4])

            (Multibooting - nowadays we are lucky we can make one installation media with multiple operating systems (not limited to just one like the old Hardy era) and so does with this one I made)

            The biggest difference to Hardy era is that now Ubuntu got many vendors sell computers preinstalled with it. Even you can now preorder from System76, Entroware, or Star Labs a laptop with 20.04 already. This reduces users needs to install and in turn reduces risks for us -- just like what vendors like Asus or Toshiba did for decades with Windows --
            (Branded Ubuntu computers - these are three new vendors namely System76 from the US and Entroware and Star Labs from the EU aside from officially certified vendors such as Dell and Lenovo)

            2. Add and Remove Applications
            Application installation: it changed a lot. From the absence of Synaptic and GDebi, inconsistency of Software Center, introduction of a new software delivery technology called Snap, despite the unchanged Debian package system (.deb - apt - repository) still powering underneath. In short, now we obtain applications mainly through the Software Center.

             (Ubuntu Software Center conveys you applications -both libre and proprietary ones- under Canonical's Snap new technology)
            (Remember this? It is the legendary Synaptic Package Manager that came with Hardy long before Ubuntu Software Center)
            When we use Ubuntu Software we use Snap. Snap is the new way we users receive applications and their updates. On the other hand, Snap is also a new way application makers deliver applications and updates they made to us the users. What makes Snap special is it standardizes other distros beyond Ubuntu and makes software makers easier to share or to sell their apps.

            (Ubuntu Software displaying installed applications)
            3. Settings
            Way of controls: they changed too and it is now centralized. On Hardy everything is scattered, while on Focal everything is centered in a control panel named Settings. This eases everyone to find their configuration quickly and repetitively despite actually we can still access them individually like before by searching on the start menu.

            (Control panel - from system identity to power management, taking care about hardware devices or language localizations, everything to configure is now centered in this gear-iconed Settings)
            (Scattered Settings - years ago, Hardy placed different places for different settings and now Focal leaves out these in favor of a centred one)
            Tweaks: Ubuntu now separates between the Settings and the Tweaks. It is understandable that Ubuntu wants to be 'just works' - it expects most users (especially enterprises and individuals) to use it as is without tweaking animations - fonts - themes - whatsoever. However if users want to, they can, but additional tools may be needed and Tweaks is the most prominent one.

            (This tool is needed if you want to disable animation, customize multiple themes, change fonts, work around window borders, and anything about makeups)4. Extensibility
            Extensibility: talking beyond defaults, Ubuntu now supports extensions to  desktop 'makeups' and its functionalities. The most excellent example is that you can couple between desktop and phone -- this magic is called GSConnect -- and continuously monitor your download upload numbers -- using Netspeed -- among other awesome examples.

             (Android phone seamlessly integrated to Ubuntu computer - a Xiaomi Redmi to receive picture files sent from my Focal Fossa laptop over wifi - notice also the download upload counter atop)

            5. Detailed Information
            Last but not least, here is more detailed info about Focal's internals.
            • Kernel version: 5.4.0
            • GNU versions: bash 5.0, coreutils 8.30, libc 2.31, gdb 9.1, grep 3.4, gpg 2.2.19, gzip 6.7.0, tar 1.7, sed 1.30, wget 1.20.3

            LibreOffice Writer: Page Formatting

            Tuesday 7th of July 2020 09:40:00 AM
            Page formatting is determining page size, margins, boundaries, and orientation. With this we prepare our document for printing papers and how it would look like in general. You will utilize menubar Format a lot in this case. Let's go!

             


            Page Size
            • A4
            • F4
            • Letter
            • Legal

            To change page size, go to menubar Format > Page > select a size among size choices > OK. You will see your right sidebar Page section confirms page size according to your selection. For F4 size, if you don't find it on selection, select User size and manually determine width=21cm height=33cm.

             (Menubar Format > Page)
            Page Margins
            • Left margin
            • Right margin
            • Top margin
            • Bottom margin

            Margins are spaces between outer and inner areas of page. To change margins, go to menubar Format > Page > insert numerical values for example 4 - 3 - 3 - 3 centimeters for the four edges left - right- top - bottom > OK. Now all pages will be formatted with margins you determined.

            (Three pages with 2-2-2-2 margins)
            (Three pages with 4-3-4-3 margins)

            (Three pages with 6-4-6-4 margins)
            Page Boundaries
            Boundaries are lines surrounding inner area of page. To add boundaries, go to menubar Page > Borders > add four lines surrounding the page > OK. Now every page will have boundaries. To remove boundaries, go to same menu and remove every line.

             (Writer document with eight pages all bordered)
            Page Orientation
            • Portrait
            • Landscape

            Do you want portrait or landscape pages? To set up, go to menubar Format > Page > Page > Orientation > choose either one > OK. Now all pages will be formatted according to your orientation selection.

            (One page with Landscape orientation)

            Collection of Multiboot Making for Distros

            Saturday 4th of July 2020 07:33:00 AM
            Thanks to my business going well with shipping many usb flash drives in Indonesia, I managed to make multiboot many distros previously I could not. Most notably are Deepin, openSUSE, Slackware which are not supported, aside from the ones automatically supported to make multiboot with notably Ubuntu family and Fedora, not to mention others. Now as I have many notes about them I want to list them out here in one place. Happy booting!

            You want to make multiboot?
            Learn first about using GLIM tool and then learn one among these tutorials.

            Distros

            I hope more GNU/Linux distros coming!

            Making Zorin OS 15 Works with GLIM Multiboot USB

            Saturday 4th of July 2020 07:14:00 AM




            In late 2019 I successfully ship multiboot drives with Zorin OS as one among many operating systems within them. I have made the articles in making them multibootable most notably openSUSE, Deepin, and Slackware, as they were actually not supported by GLIM multiboot maker. However, I forgot that I have not made such article about Zorin as I thought I have. Now I remembered it in 2020 and this is the article you can learn once again to make it bootable like what I am currently doing with my latest Zorin articles. Enjoy!




            Get Zorin OS
            Download it at zorinos.com.


            Change inc-zorin.cfg
            Create a new file named inc-zorin.cfg in your flash drive's boot/grub/ directory and save code text below.
            # Zorin
            for isofile in $isopath/zorin/Zorin-*.iso; do
            if [ ! -e "$isofile" ]; then break; fi
            regexp \
            --set 1:isoname \
            --set 2:version \
            --set 3:variant \
            --set 4:arch \
            "^${isopath}/zorin/(Zorin-([^-]+)-([^-]+)-([^-]+)\.iso)\$" "${isofile}"
            menuentry "Zorin OS ${version} ${arch} ${variant}" "${isofile}" "${isoname}" --class zorin {
            set isofile=$2
            set isoname=$3

            Screen Zoom and Mouse Indicator on Ubuntu 20.04

            Saturday 4th of July 2020 06:21:00 AM
            Ubuntu can help you to enlarge screen items and easily display cursor movements to your audience. This article is a company to Focal For Teachers and continuation to Screen Zoom on KDE. This is practicable to every GNOME operating system not only Ubuntu but also Fedora, Red Hat, Zorin and others. You can watch practical examples in this new video below and also image editing videos I published recently. For teachers and tutorial makers, this article is for you. Enjoy!

            (Ubuntu for teaching in two minutes - this video displays how to zoom in and make the cursor looks clearer to audience)
            Examples


            1. Screen Zoom
            • Enable: Alt+Super+8
            • Disable: Alt+Super+8
            • Configuration: System Settings > Universal Access > Zoom

            Don't forget that Super key is Windows key on your keyboard. For the configuration, for most cases you will only need Magnification 1.50 and Follow Cursor Movement type of zooming and no Crosshair.

            (Ubuntu 20.04 screen with large cursor, large text, cursor indicator enabled, cursor indicator, and zoom configuration)
            2. Enlarge Cursor
            • System Settings > Universal Access > Cursor Size > select one.

            Large cursor helps your audience follow your movements. It is one option when cursor indicator is not available and much clearer when combined with it.

            3. Enlarge Font
            • Enable: System Settings > Universal Access > Large Text > Toggle ON.
            • Disable: System Settings > Universal Access > Large Text > Toggle OFF.
            This is usable to make screen text looks clearer. This method is the faster one than reducing your monitor resolution.

            4. Typing Indicator
            • Enable: Alt+F2 and type command screenkey
            • Disable: Alt+F2 and type command killall screenkey

            Typing indicator or keystroke indicator displays everything you type to your screen so audience know what keys you are pressing. It is not preinstalled so you need to install it yourself (don't worry, it is easy) as the package name is screenkey.

            5. Cursor Indicator
            • Emphasize cursor: press Ctrl
            • Enable this feature: System Settings > Universal Access > Cursor Indicator
            This cursor indicator or cursor location is equivalent to same feature on Microsoft Windows. Watch the video to see it in action. 

              Note

              For Zorin 15, I found that mouse indicator is failed to show using System Settings but is easy to enable using command line below. It is thanks to Askubuntu discussion regarding GNOME.
              $ gsettings set org.gnome.settings-daemon.peripherals.mouse locate-pointer true #to enable
              $ gsettings set org.gnome.settings-daemon.peripherals.mouse locate-pointer false #to disable
              Happy teaching!

I present you here how to do that using Scale Tool and either manually or numerically shrink a picture. Below is a one minute video followed by explanations and exercises you can download. Don't forget this is the 4th part of GIMP Guide for Authors. Happy editing!
              (GIMP Resizing in one minute)

              Resizing
              • Use Scale tool (S)
              • Click on the picture
              • Eighth handles appear surrounding the picture
              • Drag one handle to any direction, or
              • Numerically type width x height values on the dialog,
              • Join the chain or break the chain in order to keep or keep no aspect ratio,
              • Click Scale button
              • Go to menubar Image > Crop to image size > picture resized.
              After resizing don't forget to Save As (Ctrl+S) GIMP document format .xcf and then Export As (Ctrl+Shift+E) actual picture file you want such as .png .jpg .gif.

              Ubuntu Phone Recap 2020

              Friday 3rd of July 2020 10:15:00 AM
              I found my community at Mastodon. They share a lot about Ubuntu Phone - particularly Ubuntu Touch operating system and its current maintainer The UBPorts Project and the hardware maker PINE64. Fortunately unexpected, two interesting things come - the arrival of Volla and also Fairphone which want to be the next Ubuntu Phone and powered with the Touch. These are interesting to cover in a short summary so this article is for you who are interested in Ubuntu Phone once again. Let's go!
              (Ubuntu Phones - photo by Ernmander from Mastodon published January this year republished here with his permission)
              In The Beginning
              Ubuntu Phone was Canonical's idea to begin with at 2011 - same years when Unity first introduced - and unfortunately abandoned at 2017. The concept was Convergence, the mobile operating system was Ubuntu Touch, and the hardware was Ubuntu Edge. Canonical wants Ubuntu mobile to work magically on desktop and laptop just by plug and play. They made a legendary crowdfunding that was closed with twelve million dollars and twenty thousands of comments. In the reality, Ubuntu Touch successfully powered BQ Aquaris, Meizu, and Galaxy phones. In the end, Canonical Ltd. as Ubuntu company discontinued Ubuntu for phone in favor of Ubuntu for Cloud and IoT.
              However, Ubuntu Phone apparently survives today not in Canonical's hand but in a small project called UBPorts who is doing everything to continue development of the Touch operating system and engage with device makers to make Ubuntu Phone real. It is truly exciting! Now we can see UBPorts efforts bear fruits as one by one Phones coming from PinePhone, Volla, FairPhone, and more.

              And for me myself, actually I have no interest in mobile phone as I am dedicated only in desktop computer field. However, if it is Ubuntu Touch we are talking about, then I am interested, and will be highly more interested when the hardware coming from our own Free/Libre Open Source Software community like Purism and PINE64. Thanks to people I mentioned in the Acknowledgement section, and thanks to Mastodon social media, I found Ubuntu Phone once again and now excited to convey this to the world. Last month I made a toot at Mastodon which surprisingly got many responses and it is the inspiration for this article. Hello world, this is Canonical's dream comes true!


              1. UBPorts and Ubuntu Touch
              Visit ubports.com - The UBPorts Project along with The UBPorts Foundation continue the open collaborative development of Ubuntu Touch mobile operating system and its user interface Lomiri (formerly called Unity8). One of amazing things created by UBPorts is easy OS installation procedure where we just install a software in computer then connect a supported phone device and click to install Ubuntu Touch into that device - very different to experiences we might have with Android 'custom roms flashing'. They are active at Mastodon (news) and Pixelfed (photos).


              The installer in action:

              (Ubuntu Touch installation from laptop to tablet - Photo by Ernmander originally published at Mastodon republished here with his permission)

              UBPorts official photos showcase:


              User testimony on how easy it is to install the OS:





              2. PINE64, PinePhone, PineTab, and Ubuntu Touch
              Visit pine64.org and their store - PINE64 is a promising computer manufacturer which focuses on ARM rather than PC architecture and they make PineBook the laptops, PinePhone the phones, and PineTab the tablets with official support for GNU/Linux operating systems. The good news is that they sell PinePhone Ubuntu Touch editions! Another good news is that their products are interestingly inexpensive. To order their Ubuntu Phone, visit their store link above.

              Everyone wants to know about PINE64 PinePhone Ubuntu Touch should look at Aral Balkan's toot:


              Video by Martijn can depict user experience of Ubuntu Phone these days:

              3. Volla Phone and Ubuntu Touch
              Visit volla.online and indiegogo.com - Volla is a new German startup who make secure phones via crowdfunding and they already ship Volla Phones with Volla OS and Ubuntu Touch in partnership with UBPorts. You can preorder one at Indiegogo link above and select Ubuntu Touch as the operating system choice.

              Volla Phone website with Ubuntu Touch:


              Volla preorder with Ubuntu Touch:


              4. Fairphone and Ubuntu Touch
              Visit fairphone.com and store - Fairphone is a phone maker company which focuses on life environment and making their hardware free software friendly. The second edition is the device promoted officially by UBPorts. However, unlike PINE64, Fairphone does not ship officially with Ubuntu Touch - that means we must install it manually after purchasing. To buy one you can go to the store link above.

              Promoted by UBPorts themselves:
               

              Photos from 2016:


              5. OnePlus and Ubuntu Touch
              Visit UBports Device Info - OnePlus is a Chinese phone maker company which the hardware are able to handle free software operating systems. Ubuntu Touch can run the best on the OnePlus One and it is currently 1st rank device according to UBPorts. You can buy one secondhand in the device info link above.

              The phone:


              Currently ranked 1st device:


              6. Purism, Librem Phone, and Ubuntu Touch
              It is amazing to see that even Purism, the maker of Librem and PureOS, interested in producing Ubuntu Phone as well that in 2018 they announced collaboration with UBPorts. Unfortunately, it seems now in 2020 the products are either not available anymore or the collaboration got cancelled. However, the idea is familiar - as Purism Librem also came to us via crowdfunding - and the phone design is adorable. I believe Canonical's crowdfunding - although unsuccessful - still inspired many of us including Purism too.



              7. More Devices
              Actually, there are more Ubuntu Touch devices in reality thanks to people made experiments with their devices such as:

              Sony Xperia:


              Nexus:


              Something fun but very meaningful:


              I believe all these can invite you curiosity once again in Ubuntu Phone.

              Acknowledgements

              Between Two Releases of Ubuntu 20.04 and Fedora 32

              Thursday 2nd of July 2020 09:47:00 AM
              Both Ubuntu Focal Fossa and Fedora 32 released in the same time April this year. They are two operating systems from different families namely Debian and Red Hat. One of their most interesting things in common is the arrival of computer companies like Dell and Star Labs (and Lenovo's coming) that sell special preinstalled laptops and PCs. I make this summary to remind myself and inform you all growth of these great operating systems. Enjoy!


              (These great computer OSes released beautifully this year)Subscribe to UbuntuBuzz Telegram Channel to get article updates directly.
              Ubuntu 20.04 LTS
              Fedora 32
                The Happy News

                My inspiration to write this comparison is Coming soon: Fedora on Lenovo a good news from Fedora Magazine. Following that, Ubuntu recently informs the availability of Dell XPS + Ubuntu 20.04 laptops. Thanks to these big news, we all excited to welcome and celebrate both Ubuntu and Fedora coming into mainstream computing worldwide - where most users meet their operating systems by purchasing computers. I also made a special article about this you can read.

                 (The big news from both websites Fedora and Canonical)
                Now more computer vendors selling both Ubuntu 20.04 and Fedora 32 laptops as we already can see companies from the UK and Netherland, Star Labs and LaptopWithLinux, now ship their LabTop and Clevo laptops worldwide with Ubuntu and/or Fedora. Of course this is another big news for us all and we are excited to see more good things happen soon.

                Borderlining with GIMP

                Wednesday 1st of July 2020 09:05:00 AM
                On your computer, with GIMP you can emphasize pictures in colorful ways. You can make red rectangle or ellipse to focus your readers to a point in a picture. Of course you can use blue, green, orange, and other colors too. It is easy to do once you know how. I present you here a new video again followed by short explanations, an example, and exercises. Lastly, don't forget that this tutorial is a part of GIMP Guide for Author. Happy editing!

                (GIMP borderlining in one minute)Borderline
                  • Use rectangle select (R)
                  • Make a rectangle selection in picture
                  • Select a color
                  • Go to menu Edit > Stroke Selection > OK
                  • Borderline applied to an area in picture
                  • Remove selection (Ctrl+Shift+A)
                  • Do the same if you use ellipse select (E) instead
                  You can adjust several things there: line color by color selector right under tools - line thickness by line width on Stroke Selection dialog - line smoothness by selecting 'Stroke with a paint tool: Paintbrush' instead of 'Stroke line' on that dialog. This way areas you want to emphasize will look clearer and it will help support your writings.



                  Example
                  As a tutorial author, of course I often emphasize my computer screenshots with color borderlines. For example, here is Zorin OS picture edited with Stroke Selection in red, green, and yellow.



                  Exercises
                  Picture being edited in the video is one among Zorin OS wallpapers just like what we saw in the previous part. I present it once again here as new exercises for you. If you don't know how to save picture yet, don't worry, simply go back to beginning of this series and do the exercises first. Happy learning!

                  Air Balloons (JPG) - download the photo. 
                  • Try to emphasize every single balloon with a red ellipse. Export to PNG.
                  • Try to emphasize different groups of balloons with red ellipses. Export to PNG.
                  • Try to emphasize only the big balloons with red ellipses. Export to PNG.

                  Cropping with GIMP

                  Tuesday 30th of June 2020 04:48:00 PM
                  With GIMP on your computer, you can crop pictures easily. The pictures are then can be inserted into your writing documents. I present you below a video and an explanation to do that. This article is one part of GIMP Guide For Authors. Happy editing!
                   
                  (GIMP crops a picture in one minute
                  Crop
                  • Crop tool on toolbox.
                  • Shift+C on keyboard = crop.
                  • Tools > Transform Tools > Crop on menubar = crop.

                  You can use either one of three ways above. Then drag and drop on canvas to form a rectangle. A special rectangle covers a certain part of the picture. Adjust the width or height by dragging the four handles. Click one handle to apply the crop. To undo, press Ctrl+Z. To redo, press Ctrl+Shift+Z (it is not Ctrl+Y here). To save, press Ctrl+S and it will be saved as GIMP's native format .xcf comparable to Photoshop's .psd (it is not the final picture). To export final picture, press Ctrl+Shift+E and determine the filename and the extension: type filename extension desired such as picture.png picture.gif picture.tiff picture.bmp picture.tga and others.

                  Exercises

                  Here are assets to crop for you. They are beautiful wallpapers you saw in video above.
                  • Aurora Borealis (JPG) - try to crop the aurora without the trees.
                  • Logotype (JPG) - crop the ZORIN wordmark like video above.
                  • Hot Air Balloons (JPG) - crop the baloons without the sky.
                  • Hexagons (JPG) - crop some deeper levels hexagons.
                  • Mountain Lake (JPG) - crop the water without the mountains.

                  Zorin OS Privacy Pack

                  Tuesday 30th of June 2020 03:46:00 PM
                  Here are my privacy and security tips with Zorin OS everyone can practice:
                   
                  Search engine - Startpage.com - visit this privacy focused search engine and click to make it default instead of Google.

                  Tracker protection - uBlock Origin - install this addon to your web browser and it will block all advertisements as well as online trackers.

                  Browsing security - HTTPS Everywhere - install this addon too and automatically every connection to websites will be forcefully encrypted.

                  Password manager - KeePassXC - install this program from software center and with this you do not need to remember your gmails, facebooks, and blogs account details anymore except one password to this program only you can open.

                  Email secrecy - GnuPG - with this emails will be encrypted in convenient ways and only the true recipients can open them. Evolution is the client preinstalled on Zorin.

                  Forgetful system - Zorin LiveCD - run the OS uninstalled on any computer from within a flash drive installation media then you get an anonymous system ready for every activity and this system wipes out all stored data once computer restarted.

                  Panorama - Part I of Ubuntu 20.04 LTS Review

                  Monday 29th of June 2020 10:53:00 PM
                  This is the first part of my review and here I talk about its Look and Feel or let me word it panorama. First, I present you here a video I name it Ubuntu 20.04 in One Minute that reveals to you the panorama of this amazing computer operating system including desktop animation effects and how one interacts with everything inside it. Second, I present you long explanations following it to emphasize the improvements since the age of Hardy Heron version twelve years ago. In panorama, it got so many changes in order to make it just works for most people yet still unique with its own humanity for human beings. So, let's go to the review and see you in the next part!


                  (Ubuntu 20.04 in One Minute - a video that portrays the desktop, start menu, system tray, panels, wallpapers, effects & animations, System Settings, and workspaces; dedicated to amuse everyone in this Corona pandemic)
                  < Preamble | Part I | Part II | Part III >
                  < Download Links | Install Guide | Afterinstall | Basics | Unity | Education >

                  Summary
                  • Identity.
                  • Menu.
                  • Activities.
                  • Searching.
                  • Headerbars. 
                  • Office suite.
                  • Wallpapers and themes.
                  • Missing things.
                  • Computers and laptops.

                   (This is panorama of a desktop computer running Ubuntu 20.04 operating system also known as Focal Fossa - notice the sharp colors and smooth forms it serves) (Picture 1.1)
                  Ubuntu panorama is now changed so much since the age of Hardy. It left Human theme set into Yaru these days - from orangeish brown-white in the past into greyish pink-white now. This is the new identity.

                  (Hardy - Nautilus file manager on left and System Identity on right - all blended in Human desktop theme) (Picture 1.2)
                  (Focal - Nautilus on left and Ubuntu Software on right and notice it is already Yaru right now) (Picture 1.3)
                  Accessing applications is now simplified using the large start menu symbolized by nine dots on bottom. A big benefit also is that now Super key works to open this menu and it's not unusable anymore. When you often use an app, you Favorite it to the left panel. You do not check multiple categories every time anymore unlike on Hardy.

                  (Applications Menu - similar to Android's way of running apps) (Picture 1.4)
                  Work with apps is now using Activities button on top corner. Multitasking works with Workspaces that appear on right edge - as we simply drag window and click over workspaces to do that. One more great thing is you can run pinned apps by pressing Super followed by numbers.

                  (Busy - this view is called Activities Overview with three apps running on current workspace and seven more running on different workspaces beside - once again similar to Android's way to present running apps) (Picture 1.5)
                  Accessing files and folders is still with Files the beloved file manager of Ubuntu which on Hardy it was named Nautilus. It is clearly simpler now. No menubar, no toolbar, no statusbar either. Its the 3rd position on left panel. Now everything is done by that black topping you see on this screenshot - where the buttons back|forward - address - blank space - search - views - preferences - close all took place. It also does not show disk partitions as they are now hidden under + Other Locations section. The biggest improvement is the search is now excellently faster. Try it!


                  (Files version 3.36 right now leaving its legendary predecessor Nautilus version 2.22 on Hardy) (Picture 1.6)
                  Browsing the internet is now up to Firefox version 75 compared to Hardy age version 3.0. It supports thousands of addons right now including the amazing uBlock Origin, HTTPS Everywhere, and so on. It grows to accept new search engines aside from Google namely DuckDuckGo and Startpage - which respect user's privacy more. It plays out of the box many multimedia formats including mp3 and mp4 now. And of course it plays YouTube without asking for additional codecs.

                  (With this old Firefox many of us started knowing the internet) (Picture 1.7)
                  (It has been transformed so much in 2020 - notice the logo is different now and also no menubar neither statusbar) (Picture 1.8)
                  Just search, everything is connected to your Super key. For example, type photo and you find Image Viewer or type screen and you find either Screenshot or settings related to your display. Continuing the start menu above, it's fairly like the examples here, now you just type anything and it appears on your screen. It's as simple as that. Interestingly, it also searches into sections in Settings and also your files and folders. 

                  (Searching - this one is unlike Android - now the system improves a lot to display better and find faster) (Picture 1.9)
                  App windows toppings are now larger and darker with everything simplified. This means no menubars anymore in Ubuntu Applications. This is the great change since Hardy age. Did you notice that?

                  (Headerbars - this is honestly now a trend among Apple and Android products - a thick titlebar with everything on it to get rid of menubars and also toolbars which are considered obsolete - notice the position of search and navigation buttons) (Picture 1.10)
                  Now Ubuntu office suite features Word 2007-like toolbars which are loved by many as you may see below. I also like this toolbar style. It is not OpenOffice.org anymore but LibreOffice - a fortunate, professional and surviving free software now everyone enjoys the benefits. We can learn so much here that our community decision ten years ago to save OpenOffice.org from proprietary company was right and now we are the witnesses of this successful free software.

                  (OpenOffice.org 2.4 with Writer, Calc, and Impress running on Hardy - do you remember those sweet days?) (Picture 1.11)
                  (LibreOffice, a successor which surpasses OpenOffice.org, version 6 with Ribbon toolbar style) (Picture 1.12)
                  Ubuntu now eases us by adding open in terminal feature everywhere. This means in your home directory, system, partitions, external hard drives, anywhere else you can instantly invoke commands as you wish without fusses anymore. This extends functionalities without limits! This feature didn't exist on Hardy.

                  (Terminal & Nautilus - they are now one click away) (Picture 1.13)
                  Changing wallpaper is now integrated within Settings and not in separate modules anymore but it's still just a right click away. However,  Specifically this control panel will be discussed in the next part.

                  (Right-click & desktop wallpaper - Focal still keep context menu in one hand and Change Background feature on the other hand) (Picture 1.14)
                  Changing theme is now simplified too. If Hardy offered multiple ones, Focal only offers three namely Light - Standard - Dark. If Hardy offered theme customizations built-in, Focal does not. The idea is easy to grasp, Ubuntu wants to be just work and assume that users do less customization - by the proof of separate application available if you want to install and customize themes.

                  (Appearance Preferences - remember this? It is where we switch desktop theme and also enable 3D cube on Hardy.) (Picture 1.15)
                  (Settings | Appearance - this is the theme switcher as well as left panel visuals adjustment on Focal) (Picture 1.16)
                  Speaking a little bit technical, GNOME is the name of Ubuntu panorama. You see Ubuntu you see GNOME. It is unchanged since the old age. However, it is now version 3.36 (see its official video) on Focal compared to version 2.22 (read its release) on Hardy. For you didn't know, every GNU plus Linux system like Ubuntu separates between its system and appearance unlike Microsoft Windows so we find that here the user interface is actually an independent product from The GNOME Project.

                  (GNOME 3.36 - Ubuntu Focal browses the official website of its own user interface) (Picture 1.17)
                  Missing things exist which maybe make us feel a little bit emotional such as dragging icons to desktop, create new panel, file manager's split vertical, 3D cubes, wobbly windows, and the excellent old user manual which was really educating for user. Outside of  these, of course we missed Canonical's ShipIt program which sent freely Ubuntu CDs worldwide that I believe made this alternative operating system popular. I was a recipient of their CDs among so many other recipients. Were you?

                  (Right showing Ubuntu website promoting Dell XPS laptops with Focal and left showing newly branded laptops proudly selling with Focal as well) (Picture 1.18)
                  Finally, to close this first part, very happy news coming from computer manufacturers as now more Ubuntu laptops and PCs we can purchase compared to the old age with Hardy. Many of them are now coming with certifications too - that means even if they come not with Ubuntu we are guaranteed to have Ubuntu running on them finely. You can read this official news to see the processes behind. They grow in numbers and qualities. This is the outside panorama fortunately we can see the reality these days. To all these vendors I wish you all success!

                    • Screenshot - pressing Alt and Printscreen keys is still taking current window as well as pressing Shift instead is taking a free rectangle area.
                    • Audio and video playbacks - Rhythmbox and Totem are still here however changed they are.
                    • Utilities - even Baobab disk usage analyzer is still here although Brasero cd burner is no more. Of course File Roller archive manager is still here too.
                    • Titlebar's context menu - right-click on windows' toppings still work.

                      Ubuntu 20.04 Review - Just Works

                      Sunday 28th of June 2020 09:44:00 AM
                      Finally, this is my review of Ubuntu 20.04 LTS Focal Fossa on its Panorama, Power, and Life for all users divided in three parts after I used it in enough period of time. I go from the point of view of twelve years ago the legendary 8.04 Hardy Heron version and the slogan Just Work we easily find when installing this amazing operating system. Once one part finished, I will update this preface article until all parts finished. I am enjoying writing this and I hope you also enjoy this review series even better. Happy reading!

                      (Do you remember this legendary wallpaper? Now it's included again in Focal Fossa after twelve years thanks to Ubuntu World Cup held earlier this year.)

                      Acknowledgement...

                      Congratulations and gratitude to all Ubuntu developers! I want to say first these things. Even at worldwide pandemic of Corona virus disease these days, Ubuntu, brings us happy news: the leading free and open source operating system still release on time at April 2020 just as expected. A fortunate release also for everyone as Microsoft Windows Seven already reached end of life earlier this year. It brings a lot of new technology improvements by keeping its usability and user-friendliness. It is an operating system for everyone in this new age. I am glad I discover Ubuntu 20.04.

                      (The slogan Just Work appears on the installation splash screen of Ubuntu 20.04) 
                      Before we begin everything...

                      Do you remember? Ubuntu is an old African word meaning humanity for human beings. That is the tagline we already are rare to see these days and thanks to 20.04 we remember it once again. In the past, version 8.04 called Hardy Heron and this year this release 20.04 is called Focal Fossa. Focal includes Hardy Heron's wallpaper, the legendary one, from the age when we still often heard that Ubuntu tagline. Now Ubuntu grew very much leaving the old times all alone thanks to the advancement of GNU, Linux kernel, and especially the GNOME 3.36 user interface we are facing now. Compare that to that old version Hardy Heron released a decade ago that looks very plain with its double panel.

                      Our computer standard today is far more advanced than the Hardy Heron age. Aside from that, nowadays mobile phones have been a norm that almost everybody use. So that Ubuntu. Now it requires better computer specification and looks more like a mobile phone than a desktop. What I can guarantee you is, any computer that runs Windows 10 well can run Ubuntu 20.04 well too. My own specification is rather very low yet it still works with my two different installations of Focal. Don't worry to try Focal right now!

                      This series will go on...

                      Life is harder these days whcn Corona pandemic spreads so I finally decided to divide my review into three parts:

                      I. Panorama
                      First part will talk about everything look and feel and state of manufactured computers availability of Ubuntu 20.04.

                      II. Power
                      Second part will talk about technical aspects especially software installation method and configuration.

                      III. Life
                      Last part will talk about everything applications and how Ubuntu 20.04 can be used in real life.


                      Hardware used...

                      Computer I use to make this review is Acer Aspire One 756 - Intel Pentium 1.3GHz - 6GB RAM - Intel HD video card - Broadcom BCM4313 wifi - Ext2 Filesystem - 14GB disk partition on a usb flash drive branded SanDisk Cruzer Blade. This is the same hardware I had since years I made many GNU/Linux reviews here on UbuntuBuzz.

                      First links first...

                      Either it is waiting this series going, or you simply are curious, you can read the announcement links first.

                      To be continued to the first part...

                      Optimised authentication methods for Ubuntu Desktop

                      Still counting on passwords to protect your workstation? When set up properly, alternatives to passwords provide a streamlined user experience while significantly improving security. These alternative authentication methods can also easily be combined to create a custom and adaptive authentication profile. This whitepaper introduces three popular authentication methods that provide a solid alternative to passwords. Perhaps you’d like to configure your laptop for login using a YubiKey hardware token connected to a dock. Another option could be to login with a Duo push notification when not connected to the dock, but use a Google Authenticator one-time password when no network is available. Maybe you need a separate hardware token just for ssh authentication, and you always need to keep a long, complex password for emergency authentication should all other methods fail. All of these scenarios can be easily configured within Ubuntu. Read more

                        If you’re tired of playing chess on a screen, then perhaps you could create a robotic opponent like Instructables user Michalsky. The augmented board runs micro-Max source code, enabling chess logic to be executed on an Arduino Mega with room for control functions for a 6DOF robotic arm. The setup uses magnetic pieces, allowing it to pick up human moves via an array of 64 reed switches underneath, along with a couple shift registers. The Mega powers the robot arm accordingly, lifting the appropriate piece and placing it on the correct square.
