How To Use Download Managers on Ubuntu and Android

Saturday 24th of July 2021 06:40:00 AM

Persepolis and Download Navi are two download manager apps for Ubuntu and Android, respectively. They can help the users accelerate download speed and keep track of what files had been saved. This tutorial will explain how to use them to download files from the internet after installing them to desktop and phone. I hope this tutorial helps Ubuntu users who have computer and phone altogether.

Subscribe to UbuntuBuzz Telegram Channel to get article updates.


About The Applications

Persepolis Download Manager (PDM) is a free libre open source, cross platform, IDM-like program available officially on Ubuntu since version 20.04 Focal Fossa.

Download Navi is an Android phone app, available freely at F-Droid app store (read our quick guide). It is a very fast download accelerator and manager for mobile users. 

Features of both apps:

  • Accelerate download speed up to 16x splits
  • Automatic naming of files (Navi)
  • Pause and resume
  • Dark theme 
  • Browser integration (Persepolis)

 

Installing Download Managers

On Ubuntu:

    • Open Terminal.
    • Press Enter after typing the command line below. 
    • Persepolis installed.
    $ sudo apt-get install persepolis

     

    On Android:

    • Open F-Droid. 
    • Search for Download Navi.
    • Click INSTALL and accept everything else. 
    • Download Navi installed.


    Basic Downloading

    Now we learn how to download a file over the internet regardless it is a document, a program, a video or audio, or anything else. The basic is you just need to get the link (URL) on web browser and insert that link into the download manager. Let's practice with this exercise website https://file-examples.com.

    To download a video: 

    • go to Video Files Page, 
    • select a video, 
    • right-click a Sample Video File,
    • Copy Link,
    • paste link in the download manager program, finally
    • start the download;
    • for the other files repeat steps above.


    I think it is clear and easy to do. Now, let's jump to the next practice.

    Download YouTube Videos

    INVIDIOUS (website) is a convenient way to download YouTube videos. For example, let us see this one hour Beautiful Nature Scenery video.

    On Ubuntu:

    • Right-click the playing video. 
    • Copy Video Link.
    • Open Persepolis and add new download. 
    • Paste the link.
    • Start download. 
    • It downloads. 
    • Once completed, the video is saved in Downloads.

     



    On Android: 

      • Open browser to the video above.
      • Click Download.
      • It plays on new tab in dark background.
      • Copy the URL from the address bar.
      • Open Download Navi, add new download.
      • Paste the URL.
      • Start download.


      The Progress and The Result


      Here's how both downloads happening and finishing. Once again, for the other types of file, the ways to download are just the same.

      Progressing with about 7MB/s speed:

      Resulting in saved videos:


      That's all. I hope this will be useful for all dear readers.

      10 Hidden Useful Tricks for Mastodon Users

      Tuesday 20th of July 2021 03:02:00 PM

      This is a list of hidden yet useful tricks for Mastodon users. For new comers, Mastodon is like Twitter but blessed with federation and privacy features. Now let's start!

      Subscribe to UbuntuBuzz Telegram Channel to get article updates.1. Dark theme 

      It's useful for our eyes and may save laptop's battery power. To enable it, go to Preferences > Appearance > change Site Theme option to Mastodon (Dark) > Save Changes > go back to Mastodon > dark theme Enabled. 


      2. Paste a Toot URL to Search Box

      This allows you to open the toot from different instance, so you can like, comment, and share the toot without opening new window. For example, this is my profile, and that is other person's profile, please notice both instances are different, so how do I comment to him? To do it, I copy and paste the URL into Mastodon's search box and amazing, I can comment!



      2. Use Simplified Federation

      Featured on Ubuntu Buzz before, it helps you follow friends across different instances. Without it, you should type your Mastodon identity over and over again just to like, comment, or follow someone in instances different to yours.


      3. Create Lists

      Lists help you watch over certain people separately. For example, you may create three lists of "My Family", "Football Friends", "Cooking Friends", which contain your family, and your football friends, and your cooking friends. For example, as I love GNU/Linux distros, I make Distros List like below. On Mastodon, Lists can only contain people you followed. To create a list:


      4. Pin Your Toots

      You can hold at maximum 5 toots on your profile. To do so, select Pin on profile under tripe dots button on a toot.



      5. Preview Toot

      There is no actual preview post feature on Mastodon, but there is a trick, that is useful. To preview a toot, create a toot > select privacy Direct > Toot! > check it in Direct Messages > to actually post it first click Delete and Re-draft > make it Public > Toot!


      6. Private By Default

      How to make every toot you publish more private by default unless you specified otherwise? To do so:

      - Go to Preferences

      - See Preferences > Other > Posting Privacy

      - Change Public to Followers-only 

      - Check opt-out of search engine to make Google etc. not indexing you (optional)

      - Save changes



      7. Featured Hashtags

      Did you see a person's profile has some special tags with numbers? Those are Featured Hashtags. They are useful to present yourself more, for example, as I often toot about free software I had #FreeSoftware featured hashtag, so everyone can click it and find all my posts about free software. To create them:

      - Go to Preferences

      - See Profile > Featured Hashtags

      - You will be offered with hashtags you often use

      - Type one hashtag, like #Sport, and Add

      - A featured hashtag created, for example, #Sport 100

      - Repeat steps above to add more hashtags


      8. Statistics

      Everyone loves statistics. On Mastodon, you can figure out how many posts you had, as well as follows and followers, block and mute, bookmarks and you can download all these data too.


      9. Stop Email

      It is useful to have your free space, to reduce unnecessary emails sent to you.  



      10. Advanced Mode

      Finally, mastodon has a beautiful, multiple column interface called Advanced Mode. Look at picture below. To enable it:

      - Go to Preferences

      - Check Enable advanced web interface

      - Click Save Changes

      - Go back to Mastodon

      - Search a tag you love, for example, #Food, #Sport, or #Nature

      - Click a tag found, then a column of that tag appears

      - Click triple lines button to the top-right, click PIN

      - Click UNPIN if you want to remove a column


      That's all and enjoy Mastodon!

      How To Play SuperTuxKart for 2 Players

      Sunday 11th of July 2021 07:52:00 AM

      Ubuntu computer can be used to play with your kids! SuperTuxKart is one game among games available that is very fun and amusing to be played with 2 players on 1 computer. You can play side by side only with existing keyboard even without additional joy sticks. Vroom, vroom, let's play!


      Subscribe to UbuntuBuzz Telegram Channel to get article updates.

      Install SuperTuxKart

      On Ubuntu you can get it by doing command in Terminal:

      $ sudo apt-get install supertuxkart

       

      Run the Game

      Find the game on your menu by name SuperTuxKart with the logo of a penguin driving a red car.

       

      The Basics

      For 1st player, the movement keys are ARROWS Up, Left, Down, Right and the select key is Enter.

      For 2nd player, the movement keys are LETTERS W, A, S, D and the select key is 0. This is what we want to configure below.

       

      Initial Configuration

      In order to play with 2 players, you must have two usernames, two different keyboard setups, and enable Vertical split. Player 1 is already existed so we just need to create player 2 username. This way, you can play it together with your existing keyboard. 

       


      To create player 2:

      1. Go to Options. 

      2. Go to Players. 

      3. Click Add. 

      4. Select Offline Accounts. 

      5. Type name like "krita" or "puff" under Local Name. This will be player 2.

      6. Click OK. 

      For example, on my computer, player 1 is "penguin" and player 2 is "fox".


      To create player 2's keyboard:

      1. Go to Options.

      Ubuntu 21.04 Review - A Fun Computing

      Saturday 10th of July 2021 07:19:00 AM

      This is our review of Ubuntu 21.04 Hirsute Hippo. This release is a dedication to Adam Conrad, a respected Ubuntu Developer, who passed away earlier this year. It is a fun computer operating system, quick and responsive on today's hardware standard, with full of useful apps and amusing games, with a few of challenges and shortcomings. Let's see it together.

      Subscribe to UbuntuBuzz Telegram Channel to get article updates.
      What's New?

      Among many others, here's the highlight: 

      • Hippopotamus theme by the codename Hirsute Hippo.
      • 2.6GB and 1.1GB size for Desktop and Server, respectively.
      • Wayland is officially the default. 
      • Active Directory (AD) support at the installation time.
      • ZFS technology choice at the installation time.


      What's new in Ubuntu 21.04

       

      1. Installation

      Hirsute takes about 15 minutes to complete the installation to a laptop. Now, Ubuntu supports corporate users who work with Microsoft's technology as it features Active Directory (AD) domain configuration built-in visible in Ubiquity. Post-installation, at the beginning user will be presented with a nice welcome, a privacy setup, and an All Done! message before going to the workspace. If user installs Ubuntu in dualboot mode, the bootloader appearance is still the same as the usual GNU GRUB 2.


      2. Appearance

      Here's how Ubuntu Desktop 21.04 looks like. Picture below is taken with 1920x1080 (1080p) display resolution and Hirsute desktop looks fit & proper on it. It features a hippopotamus as the wallpaper, as usual, with orange-pink-purple color theme. For Windows and MacOS users, its right and fixed top panels are its trademark.


       As a bonus, please enjoy this slideshow of Ubuntu Hirsute.

      1900's

       

      3. Applications Included

      Hirsute offers latest and greatest of today's Free Libre Open Source Software (FLOSS) applications by default. The names are the same but the versions are mostly upgraded for example Firefox web browser's now v88, LibreOffice document suite's now v7.1 Community Edition, and GNOME Apps are now v3.38. Visit here to see them all.

      For new comers, you may notice it follows standard buttons on the right of each window -- however, each window's title bar is huge. Only with Firefox, it doesn't have title bar separated with the contents, but rather combined with tab bar, which can be reverted back by going to Customize menu and enabling both Title bar and Menu bar.

      4. Performance

      Hirsute makes use of ~800MB. It still works on a computer with 1500MB of memory. On a 10 years old laptop, Pentium 64-bit, Hirsute works with 2, 4, and 6GB of memory. However, it works fast and responsive on ThinkPad T430 with Intel Core i5 processor.


      5. Subtle Improvements

      There are several small but noticeable improvements we will find in Hirsute. For example, our daily tools got fresh designs & new features, such as Backup, Screenshot, and Software & Updates. Let's visit them.

      Software & Updates under the Updates tab now incorporates Snap package updates. What is Snap? You might find our Snap explanation useful (click here).

      Screenshot got a new design! It is more compact, clearer to see and use. Full, window, and free shot options are now displayed in three large buttons horizontally rather than three small radio buttons vertically with Delay timer displayed at the bottom. Notice the round corners at the bottom of its window? That's the sign that Ubuntu will eventually updates its apps to GNOME Apps v40 and yes several apps in Hirsute are already v40 such as Calculator.


      Backups (also known as DejaDup) got new design too. It's now simpler with only two options at the beginning, and further configuration later. Ubuntu makes the user able to backup to Google Drive automatically thanks to Backups. 

      Software now can inform the user about sources of an application whether an app is from official repository (DEB) or Snapcraft.io (Snap) if available. Like example below, an app called Snap Store installed (called Ubuntu Software at application menu), is shown to be a Snap, not a DEB, that can be updated from Snapcraft.io.



      6. Application Installation

      To add/remove apps, we use Software. It is the central place to manage all apps and updates. Generally, Ubuntu applications are divided into two kinds, the official packages (DEB) and the Snapcraft packages (Snap), user may choose in Software. In general. one first run Software and then search for a wished app and then press Install button to finish it and finally run the app from the Application Menu.


       Today, Ubuntu is able to install apps from the central website, Snapcraft Store, by using web browser which will immediately runs Software once the Install button pressed. 7. Daily Life Purposes and Games

      Generally everything is centered into Files, the file manager, as we work with all data and folders in it. Ubuntu Hirsute can read write Windows' disk drives so you will find it convenient to just open the partition and work with the files if you are dualbooting. Viewing photos done with Image Viewer. Managing cameras done with Shotwell. Working with text documents done with Writer. Speadsheets done with Calc. Presentations done with Impress. For internet purpose, we have Firefox to browse the web and Thunderbird as our handy mail box.

      Viewing pictures are all easy with the Image Viewer since years at Ubuntu. Alternatively, on the same system we are also powered by Shotwell, a powerful camera & photos management tool, which is able to help arranging and cropping photos. These two are interchangeable if user wishes.

      Document makings are done with Ubuntu's office suite, LibreOffice. On Hirsute, it reached version 7, which had superb features like better Tab Bar (similar to MSO 2007) and better compatibility. User uses Writer to produce normal text documents including PDF files, Calc to produce spreadsheets and charts, Impress to produce impressive presentations, and Draw to edit PDF and produce everything similar to what MS Visio can produce.

      Browsing the internet, web and emails are done with the long living Firefox and Thunderbird on Ubuntu. On Hirsute, they reached versions 87 and 78, respectively.

      There are thousands of video games available on Hirsute. It also includes education games for school kids. When you open Ubuntu Software, you will be offered plenty, however there are proprietary licensed as well in there. Here's several games available (marked [*] is proprietary):

      Tux Typing and Tux Paint -- edu games for kids.
      SuperTuxKart -- funny racing similar to Crash Team Racing.
      OpenArena -- fast-paced multiplayer, 3D first person shooting.
      OpenRA -- war oriented real time strategy, similar to Red Alert.
      Flare RPG -- adventure, role playing game similar to Diablo.
      Megaglest -- medieval fantasy 3D game similar to Warcraft and Empire Earth.
      Wolfenstein[*] -- 3D shooting like Counter Strike.Steam[*] -- the famous portal of mainstream games.

      8. Graphics Purposes

      Ubuntu Hirsute supports your art & graphics purposes. Do you know that since years Ubuntu provides for us very good graphics software, used by professionals? Look at a beautiful table of applications below, by PIXLS, a Free/Open Source Photography community, the good news is that almost all applications mentioned here are available on Hirsute. More good news is that more graphics apps are still available on Hirsute even though they are not listed at PIXLS.


       

      Below is Image Viewer showing some beautiful photos of aurora and scenery. Photos displayed are taken from our favorite public domain source Unsplash.com.

       
      Below is Rawtherapee, one of tools used by PIXLS community, running on Hirsute to process photos. For those from proprietary software world, Rawtherapee is a similar tool to Adobe Lightroom.



      Below is Gimp, also one of PIXLS community tools, the infamous free/libre and great image editor for all computer users, available too on Hirsute to edit photos similar to what Photoshop is used for. 
      Lastly, below is Inkscape, one among great tools not mentioned by PIXLS, running on Hirsute to draw illustrations and edit vectors similar to Illustrator or CorelDRAW is used for. Artwork displayed is Island of Creativity by Bayu Rizaldhan Rayes the winner of Inkscape 2019 world contest.



      9. Educational Purposes

      Ubuntu Hirsute provides and supports many educational fields. It provides a clean user interface with accessibility features.

      (Scilab with Xcos, a mathematics suite, a replacement to Matlab and Simulink)

      Hirsute is also ready for teaching purposes especially the online one. As I run an online classroom using a combination of Telegram and Jitsi or BigBlueButton technologies, I can say doing it with Hirsute is nice. Below is a picture of one of my classes from June 2nd depicting in clockwise order, Telegram as the main classroom for students submitting all assignments, BigBlueButton as the screen sharing viewport, file manager showing course materials written and are readable with LibreOffice, the online course website, and the schedule table (created with Writer).



      10. Software Development Purposes

      Ubuntu Hirsute provides complete suites and choices of software development for developers. For complete desktop solution, we are offered the world class leading technologies, which you can use to develop cross platform desktop applications, among them are Qt SDK, and Glade + GTK, and Lazarus + FreePascal, and also Netbeans + OpenJDK. For web solution, we are also offered with the most popular technologies like PHP, Nodejs, and Django. The user can install them with Software or APT. These mentioned names does not limit the vast selection of other languages, libraries, and programming tools and utilities we will encounter on Hirsute.

      Below is Qt SDK to develop apps by drag and drop in Cpp language:

       

      (Designer, a part of Qt SDK, is being used to create a web browser application)

      And below is Lazarus IDE to develop same kind of desktop apps by drag and drop too in Pascal language:

      (Lazarus, a cross platform tool to develop cross platform GUI apps)


      11. Relationship with other OS Releases

      At the same time Hirsute releases, there are several other operating systems and technology also release altogether. Among them are, from the free software world, Deepin 20.2 and  Fedora 34 released alongside a happy news from Slackware 15 (finally announces its beta after five years of development) from GNU/Linux family and OpenBSD 6.9 from BSD family; while on the other hand from the proprietary software world, Hirsute comes at the era of Windows 10 and MacOS Big Sur.

       (This is Fedora 34 with the phenomenal GNOME Forty)

      Speaking about technologies other than OSes, Hirsute comes at the same time GNOME 40 (also known as Forty) releases as well as Plasma 5.21. We can hope for sure the next Ubuntu, Impish Indri, will include Forty desktop October this year.

      12. Compatibility with ThinkPad and Shortcomings

      We confirm that our test laptop, Lenovo ThinkPad T430, works well with Ubuntu Hirsute by all hardware detected and are functional. It is fast and responsive. All 4 USB ports work. Display, keyboard and touchpad as well as the red TrackPoint work as expected. Both bluetooth and wifi detected, work as expected. DVD-RW works as well. Indicator leds and the additional buttons over the keyboard all work. Lastly, the kill switch also works. As an important addition, our internet access tool, Huawei Mobile Wifi, works with the Hirsute ThinkPad either it is via wifi or automatic USB tethering. See our hardware list at Linux-Hardware.org.


      Minus points in this release to our understanding are:

      • It requires good hardware by today's standards and not suitable anymore on old (32 bit), lesser hardware (like 1GB memory, for example).
      • Unable to kill Firefox by name anymore with killall command.

       

      Conclusions

      Ubuntu 21.04 Hirsute Hippo is a fun computing for modern days. It works fast and responsive on a Thinkpad laptop. It sets out to be a standard of computing by competing with other desktop OSes namely Windows and MacOS with its own way -- with pinkish purple, animals, and GNOME. Once again, it just works. Last but not least, thank you Adam Conrad for all and everything humanity for human beings you have done on computing, on GNU/Linux and FLOSS, and especially on Ubuntu.

      How To Download openSUSE using Metalink

      Monday 5th of July 2021 03:02:00 AM

      Most operating systems can be downloaded in several ways we can choose which are usualy direct links and torrents. Unique among them, openSUSE is one that can be downloaded in another way which is called Metalink. It is a way of download, a technology, that joins direct links, mirrors and torrents in one to improve download speed and fix errors automatically. If you want to download this way, even for stuffs other than openSUSE, then this article is for you. What I can tell you as a daily torrent downloader is that Metalink is really fast. Now let's try.

      Subscribe to UbuntuBuzz Telegram Channel to get article updates.

       

      Tools

      To do this, we need programs that support Metalink technology you may choose:

      - Aria2, installable on any OS

      - KGet, installable on any GNU/Linux


      On Ubuntu, you can install both tools by a command line below:

      $ sudo apt-get install aria2 kget

       

      Where to download openSUSE

      software.opensuse.org is the download place of openSUSE. For a release, openSUSE may release a bunch of download options which user can choose, which are normal download (.iso), mirror download (.iso), BitTorrent download (.torrent) and Metalink (.meta4) and old Metalink (.metalink).

       


      Where to find metalink downloads

      To find that metalink option to download by example of openSUSE Leap 64 bit Full DVD:

      1. Go to download place.

      2. Find the page where all DOWNLOAD buttons available. 

      3. Click the option button and find Metalink and click. This will download a file which name ended with .meta4. This can be downloaded with ARIA2.

      4. Alternatively, click the option button and find Pick Mirror and click. On the new page opened, click the link which ended with .metalink. This can be downloaded with KGet. 



      Download Metalink with ARIA

      You are expected to master the basics of command lines to do these.

      1. Run Terminal. 

      2. Go to the download folder. 

      3. Find the file which name ended with .meta4. 

      4. Run the aria2c command line followed by the file name, for example:

      $ aria2c opensuse-x-y-z.iso.meta4

      5. Wait for the download to finish. 

      To pause, press Ctrl+C. To resume, simply repeat the same command in the same directory.



      Download Metalink with KGet

      An easy and user friendly way to do Metalink download is by using KGet.

      1. Run KGet. 

      2. Drag and drop the .metalink file from browser to KTorrent window. 

      3. Alternatively, drag and drop the .metalink file from file manager.

      4. KGet will ask you further the file(s) to be downloaded and in this example it is openSUSE by 4 GB size so give check mark to the file you want and click OK.

      5. Wait for the download to be finished.

      In this example, on a broadband connection I usually use I got a 8 MegaByte per second speed (openSUSE will finish in 15 minutes) with Metalink while usually I can only get maximum 3 MB/s with BitTorrent.



      About openSUSE

      openSUSE is a German originated computer operating system with green lizard logo that is free, libre, and open source software. As an OS, openSUSE can be installed to any PC, laptop and server just the same as any other OSes like Windows or MacOS.  openSUSE is developed by a team of community, funded by SUSE company, with world wide community members based on GNU/Linux operating system and is tightly related to the commercial SUSE Linux Enterprise operating system. It is popular with its easy to use thanks to YaST feature that represents a central of all aspects of openSUSE's configurations starting from the system install to everything else. It is made available in two choices, Leap and Tumbleweed, to fulfill the needs of both Stable and Latest Technology for all users. Visit its website at www.opensuse.org.

       

      About Metalink

      Metalink is a technology to download big files over the internet. It downloads by combining normal download links, mirrors, and P2P in one resulting in faster download speed -- can even faster than BitTorrent. Several operating systems provide their downloads as Metalinks, as an alternative offering to Direct Link, Mirrors and Torrent, for example, openSUSE and MidnightBSD and also do great free software projects like LibreOffice. To download Metalink, user should use a program that supports Metalink, for example, like Aria2 and KGet mentioned above. Visit its website at www.metalinker.org.

      How To Disable Camera Permanently on Firefox Browser

      Saturday 26th of June 2021 03:48:00 AM

      To disable camera permanently on Firefox, open the menu button > Preferences > go to Privacy & Security settings > Permissions section > find Camera > click Settings > check Block new requests asking to access your camera > Save Changes > finished. Now every website requiring camera will automatically be blocked to access the camera. For example, it is useful if you often do screen sharing via video conferences but had been disabling manually every camera access so with this trick now you will have it disabled automatically in every conference while all other features like microphone (voice) and text (chat) still work normally. Another important benefit is that now you can disable your camera without putting a sticker to cover it physically. Happy conferencing! 


      Camera privacy settings:

      Disabling camera and save the changes:

      To enable camera again, simply go to the same settings and uncheck Block new requests asking to access your camera and Save Changes.

      This has been practiced on Firefox version 81 with Jitsi Meet.
