Creating Text | Inkscape

Saturday 6th of March 2021 10:28:00 AM

This is the fourth of Inkscape For Students the series after we learned about Fonts before, now we will learn how to create text. When doing design with computer, you will find text is an important part -- you will earn so much by just learning text alone. This is why this series invite you to practice firstly with text before shapes and colors. Now let's learn and practice!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.


Summary

  • Fill and Stroke 
  • Text Tool (T)
  • Write text
  • Choose font
  • Color text
  • Formatting text
  • Transforming text

 

1. Fill and Stroke

 

Fill is color of the content. Stroke is color of the outer line. Picture below will help you understand it.

Text above is an English word WELCOME! typed with the font Liberation Sans with four different styles. The red fill as well as the black stroke can be replaced with green, blue, yellow color etc. This is the basic of text coloring.


2. Text Tool 

Text Tool (T) is the tool you will use to make text in Inkscape. It is located on vertical panel on left, above Gradient and under Calligraphy tools. When it is activated, you will see a Text Toolbar on top and Text Properties on the sidebar on the right.

Below is Text Toolbar divided in 4 sections:


Descriptions:

  • (i) font selector, format selector, text size selector.
  • (ii) vertical distance, alignment, super/subscript, horizontal distance.
  • (iii) horizontal distance, word distance, horizontal kerning.
  • (iv) making vertical, horizontal, rotational text; writing mode, text direction Left-Right (like Latin) / Right-Left (like Arabic).

3. Create Text


Use Text Tool (T) and click on the canvas and type a word and press Esc. This is the basic of making text in Inkscape.



4. Change Font


Use Text Tool and click the text and block select it and select a font from Font Chooser on toolbar. For example, change a text font (typeface) from Times New Roman to Liberation Serif.


5. Change Text Size


- Using Select Tool (S)
- Using Text Tool (T)

Use Select Tool and select the text and 8 arrows appear around it and drag one to resize the text either it is shrinking or enlarging. 


6. Color Text


- Color Swatches
- Color Palettes
- Eyedrop Tool (D)

To color a text, select the text, and click a color from the palette. To color the outline of text, hold Shift and click a color. To copy an existing color from an imported picture into the text, first select the target text, second activate Eyedrop Tool (D), and finally click the existing color.


7. Format Text


Formatting a text means making it looks like what you want. Changing its thickness (Bold), leanness (Italic), and of course size (Size) and alignment (Alignments) are things involved in it. You can use Inkscape to create such formatted text.

  • To make a text bold, use Text Tool to select it and click Bold.
  • To make it italic, do the same and click Italic.
  • To align a paragraph left, do the same to it and select align left. 
  • To align a paragraph justified, first use Text Tool to create a text box, then make a paragraph in it, select all, and finally select align justified.

Below is example of basic text formatting. They are an English word WELCOME written in three different formats namely regular (default formatted), bold, and italic.


Below is example of alignments. They are welcome words in several different languages aligned left, center, and right, and also justify.




8. Text Spacing


Text spacing can be controlled freely in Inkscape. You can make blank distance between writings as you wish, either it is vertical or horizontal, either it is between letters or even words.

Vertical spacing. Change this to control space between stacked text lines.

Horizontal spacing, letter wise. Change this to control space between letters, numbers, or characters selected.

Word spacing. Change this to control space from word to word.

Kerning. Adjust this to 'move' a letter horizontally so it pleases your sight while surrounded by another letter(s). Learn more about kerning here.

Below is example of vertical spacing:



9. Transform Text

 

Text can be transformed in a way or another in Inkscape. They are resizing, rotating, and flipping. 

  • To resize a text, use Text Tool, select it, and select a size among size selections (12pt, 16pt, etc.) from the Font Selector. 
  • Alternatively, resize text by Select Tool, select it, and drag one of 8 arrows surrounding it around. Additionally, holding Ctrl key will make it proportional.
  • To rotate a text, use Select Tool, click the text, click it once again, and drag one of 8 rotating arrows surrounding it. Additionally, holding Ctrl will guide your rotation rigidly. 
  • To flip a text, use Select Tool, click the text, and click either Horizontal or Vertical flip button on the toolbar.


Afterwords

That's all for this time. You have learned basics text creation in Inkscape including how to type, color and manipulate it. Next time, according our Table of Contents, we will learn about drawing and coloring. Finally, I wish you enjoy this. See you next time!

Codeberg Code Hosting is now with Documentation

Tuesday 2nd of March 2021 10:11:00 AM

Codeberg is now the only Gitea-based code hosting with its own user guide & documentation! This guides everyone to start their public software development with ease -- similar to the guide GitHub users enjoy for years. I like Codeberg as I frequently mentioned it (see here, see here) as the Free Libre Open Source Software code hosting. It is certainly good news and everyone is invited to improve the documentation together. Congratulations, Codeberg!

Testdisk to Recover Data from Deleted Flash Disk Drive

Sunday 28th of February 2021 03:34:00 PM

I deleted my flash disk drive. There were many files and folders within it -- now they are gone. Don't throw away nor wipe it out first, that's the advice I often heard. The secret is, actually we can save those data -- this is called recovery or undelete -- with certain hardware or software. Fortunately, gratefully, there is the best recovery software on GNU/Linux we can use, that is Testdisk, that has a very high success rate and is able to recover my data. I managed to recover 100% of one of my important folders with it. Below I share with you how I use it. You can practice this either on flash drive, hard disk, or SSD. I wish you success!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.Preface

I deliberately sacrificed my "hard disk" (a 32GB EXT2 USB flash disk drive actually) by doing resizing and experienced fatal failure. My data inside were Kubuntu operating system and thousands of files (yes, I installed OS not within HDD but simply USB flash drive). I want to test the Testdisk Tool as many of my friends said using it they managed to recover their hard disks by 100%, 90%, or 80% or so. That's really nice and now is my chance to do it too! Please keep in mind that recovery does not guarantee 100% success and results may vary between us -- so do this at your own consent and responsibility.


Requirements
  • You understand your own filesystem (directory structure, folder names, hidden files, addresses of your disk partitions, etc.).
  • You have basic ability of Terminal's command lines.
  • If you don't, you ask a friend who does.

 

How To Play

- Press Enter and Q to go next and go back, respectively.

- Press P and Shift+C and C to list files, Copy selected files, and recover them, respectively.

- Use arrow keys to move selection.

- Press colon ( : ) key to select one file/folder.

- Red and green text mean unselected and selected, respectively.

- Read carefully text on bottom every time you select a thing.

 

Get Testdisk

Add the program Testdisk first to your computer.

$ sudo apt-get install testdisk


First Step

I scan my flash disk drive. This is to find deleted disk partitions.

- Run the command line. 

- Select [ No Log ], continue.  

- List of drives appear including the deleted drive.

- I select the deleted drive.

- Select [ Proceed ], continue.

- Select [ Intel ] if the Hint says Intel, continue -- choose accordingly. 

- Name of the deleted drive appears with list of commands underneath.


Second Step

I list my deleted files. This is to see the files and folders which are supposed to be deleted or wiped out.

- I select [ Analyze ], continue.

- Select [Quick Search] command, wait.

- Partitions in GREEN appear.

- Select the deleted partition.

- Select [ Deeper Search ] command, continue.

- Wait for the process to finish. This may take a long time.

- Once finished, list of partitions appear. 

- Select the deleted partition.

- Press P key.

- List of directories appears from that deleted partition.


Third Step 

Finally, I copy and paste, copy a deleted folder from deleted partition, and paste it to my laptop hard disk drive. Recovery done!

- List of directories appears. 

- I navigate to the directory and files I want to recover.

- I select a file by pressing colon ( : ) key, the file goes GREEN.

- I press Shift+C, now my Home file system appears.

- I choose a destination folder within my HDD filesystem.

- I press C to process the recovery and save the files in the destination.

- Wait for the process to take place. The screen will say "Copying, please wait... 9458 ok, 0 failed". This may take long time. 

- Once finished, the screen will say "Copy done!".

- Files and folders recovered in the destination folder.   

 

Results

Below are my recovered folders and files. I just need contents of my Documents (99% success) and Pictures (100% success) -- because my business and teaching data were there (including my GnuPG key). Finally I can backup my Ubuntu Buzz screenshots as well as sales data.

My recovered 'Documents' folder:


My recovered 'Pictures' folder:


My sales data fortunately recovered:


IMPORTANT: please take notes that recovery may not always 100% success. So there will be some inconsistency or errors such as this example above, some strange files incorrectly placed in that folder.


Afterwords

Recovery is highly possible with Testdisk. In my case above, I got 100% success rate. There is no guarantee we can always recover perfectly but it is certainly worth trying. Do not throw away, nor write anything into, nor wipe out a deleted hard disk drive you have! I wish you success.

Starting LaTeX on Ubuntu with the User Friendly Gummi

Saturday 27th of February 2021 03:40:00 AM

Academics people and alike tend to love documents written with LaTeX -- one of the best text creation systems you can run on computer. The benefit is, the resulting document is truly beautiful. To start making LaTeX document on Ubuntu, you can start with the user friendly application, Gummi, which features preview. This short tutorial includes examples for basic texting and several math formulas. Now let's learn!

Subscribe to UbuntuBuzz Telegram Channel to get article updates.What is LaTeX? 

It is best to know LaTeX from the examples so you can grab PDF documents from KDE (KBibTex) and arxiv.org (Guix) among plenty plenty others to see how a LaTeX document looks.

(A beautiful book you can write too -- this is page 9 of KDE KBibTex program's user manual which is produced with LaTeX)

Basics

In LaTeX, basically you create everything with a start and an end. Everything is code with some frequent examples shown below.

Bold: \textbf{?}

Italic: \italic{?}

Underline: \underline{?}

Footnote: \footnote{?}

Bullets list: \item

Preparations

Install software needed to write LaTeX documents on your computer. Just run command below:

$ sudo apt-get install gummi texlive
First Step

Open start menu and run Gummi application. 

 

Create A Document

- Click File > New > a blank document appeared.

- Copy and paste this LaTeX code below.

- You instantly see the preview on the right.

- Click File > Save > give it file name document.tex > OK.

- Document created.


The code:

\documentclass{article}
\title{\textbf{Hello, \LaTeX!}}
\author{Ade Malsasa Akbar}
\begin{document}
\maketitle
\section{Introduction}
Hello, this is my document written with not word processor but {\LaTeX}.

\section{Basic Text}
I am a knowledge seeker who loves knowledge and now trying how good
{\LaTeX} is. Apparently, it is truly beautiful! It supports
\textbf{BOLD}, \emph{ITALIC}, \underline{UNDERLINE}, and also bullets
and numberings. Do not forget pictures as well.

\section{Mathematics Text}
Below is some examples of math formulas.
\newline
Basic addition: $ 1 + 1 = 2 $
\newline
Basic multiplication: $ 2 \times 2 = 4 $
\newline
Basic fraction: $ \frac{1}{2} $
\newline
Basic trigonometry: $ \cos (2\theta) = \cos^2 \theta - \sin^2 \theta $
\newline

\end{document}
The result:
The program when writing:
Example above should be self-explanatory that basically, \textbf{?} is BOLD; while mathematically every formulae should be wrapped in $     $ (a pair of dollar signs) and \times is multiply sign. You can grasp the rest yourself.  To create another document, simply copy paste example above and adjust everything else as you wish.

Edit Document

From the example above, please try to:

  • change the author name to yours,
  • change the title as you wish,
  • make some other bolds, italics, and underlines;
  • change the formulas by adding more additions, fractions, and cosines or sines;


Create PDF

Click menu File > Export as PDF > a PDF document produced in same folder as the .tex (dot tex) document file. Now your document can be opened in all computer devices including smartphones and can open collaborations with people across different operating systems.

 

Afterwords

That's all as a starter. I wish you feel the best experience of writing from here. For more exercise, try to read Wikibooks of LaTeX it gives you so many many examples to try. Enjoy writing!

Debian, KDE, and Trisquel Developments are now using GitLab

Friday 26th of February 2021 01:30:00 PM

It is exciting that now big software projects are using GitLab for their own development. Debian, the universal operating system, and KDE, the best computer user interface plus applications compilation, and also Trisquel, the completely free software computer OS are among them. You can click those mentioned links to get involved in the software developments. It is certainly a good news as it is good example for the other projects in sovereignty of the infrastructure (borrowing Trisquel's terms). I made this article after the Rocky Linux's one as I just realized how important it is. However, as an addition it is also good if there is a project maintains their own Gitea (instead of GitLab) infrastructure as both are certainly libre software. I wish the best for them all!

Rocky Linux, The CentOS Alternative, is now Using Gitlab

Friday 26th of February 2021 12:58:00 PM

This is a good example, that, Rocky Linux is now using GitLab, not GitHub, for its public development (software packaging) that everyone can join. We see in February 2021 it proudly presents its own serve  we can see it here https://git.rockylinux.org. Rocky is a continuation of CentOS GNU/Linux which is now in rapid development with its rapidly growing (despite new) community. This means Rocky is following Debian, Trisquel OS and the other big OS projects to use the Free Software code hosting GitLab (and alike). This is certainly a good news to see more libre software forge being used in real life by big projects. To contribute to Rocky, especially when you are sysadmins and in server businesses, you can click here to Get Involved. Finally, I wish the best for Rocky and its development.

Useful Tips & Tricks of Kubuntu KNotes

Thursday 25th of February 2021 04:41:00 AM
Kubuntu computer users benefit from its useful tool KNotes that is helpful to use everyday. For example, you can keep frequently used text in it and copy paste them quickly at any time you wish, such as chat group rules (including classrooms) and your online payment information. This is a list of tips and tricks using the sticky notes. Hope you will like it!

 Subscribe to UbuntuBuzz Telegram Channel to get article updates.

First Launch

When you first launch KNotes, you might find it asks for a storage location, so just follow and choose the place offered. Once launched, you can use it. See below, when all my notes are being opened on my Kubuntu laptop (I apologize it is all in Indonesian language as all my students & buyers are Indonesians).


 

What you can note?

For example, in quick way you can keep:

- basic notes, as in studying & learning 

- your groceries and schedules 

- your payment info, so buyers can pay money quickly to you

- phone numbers

- people's names & addresses

- rules & similar texts

- and many more!


Run at Startup 

Add KNotes in Autostart. To do so, open your start menu > Autostart > click Add Program ... > type knotes > select KNotes app > OK > done. Now Knotes will always be active on your system tray.

Create A Note

Click New Note when you right-click the yellow KNote logo.

Open a Note

Click a note among notes when you click the yellow logo.

Change Note's Name 

Double-click an opened note's title.

Color Notes

Paint it red, green, blue or one of available colors. To do so, right click an opened note's title > Preferences > Display Settings > change the Background color > OK > done. Do the same to the other notes. Example below showing my notes used in my daily life especially for teaching and commerce.


Search

Have many notes? No problem. Find a certain note easily with search. To do so, right click the yellow one > Find > type a keyword on the appearing dialog > found it. Example below is searching a frequently used word 'gnu' among my notes.


Show Notes Number

Finally, it can display '10' if you have 10 notes, and so on. To do so, right-click the yellow logo > Configure > Misc > give check mark to 'Show number of notes' > OK > done.

Afterwords

Some example from my daily life as I teach & trade via Telegram (a free fast messenger) are that KNotes is extremely useful to me for copy pasting classroom rules and also sending my buyers a price list + bank account as I sell GNU/Linux bootable flash drives. What I do? For years, I just need to copy and paste right from my system tray -- yes, the yellow logo!


That's all & happy computing!

Top 10 Useful Tips and Tricks for Kubuntu Users

Monday 22nd of February 2021 06:07:00 AM
Kubuntu computer users benefit from its full featured file manager and desktop. Here's my personal collection of tips & tricks on Kubuntu you might find them useful -- as I use and teach it daily for years. You will be able to do everything easily and easier, like bulk conversion as well as managing files more efficiently plus some others. Now let's go and enjoy!
Subscribe to UbuntuBuzz Telegram Channel to get article updates.
The Basics
- KDE: Kubuntu's user interface, the K in Kubuntu name, formerly means Kool Desktop Environment.

- Dolphin:
Kubuntu's file manager, you access folders & disk drives with it.

- Konsole:
Kubuntu's terminal, you command with it.


1. File Manager Split
Press F3. You can compare two different folders in one window side by side.

2. File Manager's Konsole
Press F4. You can open an integrated Terminal right within Dolphin without opening a separate one -- automatically following wherever you are in the filesystem. Excellent feature both for teaching and working currently exclusive for KDE users only.
(Picture of Dolphin with F3, F4, and F11 features all enabled simultaneously)

3. Bulk Image Resizer+Converter
Right-click several pictures and Convert them at once or Resize as you wish, easily and quickly. Excellent feature exists only for KDE users today. Extremely useful for graphic designers and alike. Read the guide here.

4. Additional Info View
Press F11. You can see file preview & properties on the right panel. Very useful for example if you have wide screen.

5. Tooltips Preview
Useful for previewing between images quickly in zoom. Enable it from the menu Settings > Configure Dolphin > General > Show Tooltips > OK.

6. Bulk Renaming
Use KRename to change name of multiple files at once. As its name suggests, KRename is a part of KDE and Kubuntu. Very useful for those who often work with thousands of files. Read the guide here.

7. Android File Transfers & More
On Kubuntu, right-click and send to Android -- and vice versa -- on Android, hold tap and share to Kubuntu desktop. You can transfer multiple files at any time with as many devices as you want. This works with wifi connection (no internet required). Excellently useful for daily use, for example, to transfer photos. The name of this feature is KDE Connect. Read the guide here.

8. Drag and Drop Pictures
You can drag and drop pictures right from the appearing notification or the image viewer Gwenview to anywhere. This convenient feature means you can send them quickly to Telegram. I benefit from this as a teacher.

8. Quick Access
Like magic, press some keys and computer does exactly a thing you want -- that is fully supported on Kubuntu. You can make custom shortcut keys to open a certain feature, program, or command -- or combination of them. You can also create new and edit existing start menu items. To do so, go to System Settings > Shortcuts to associate keys with commands you want -- and right-click start menu > Edit to change its items.

10. Quick Kill Programs
There are several ways to quickly kill hanged program. These are useful for troubleshootings:

- Press Ctrl+Esc then find program name then right-click and Kill
- Press Alt+F2 then type xkill then Enter then click the Skull cursor on an app
- Open Konsole and type killall firefox to force close Firefox, just change firefox with other program's name

11. Money Currency Check
Press Alt+F2 and type 1 USD in IDR to convert one dollar to Indonesia's Rupiah. Just change the IDR to JPY, CNY, or MYR for Japan's, China's, or Malaysia's currency respectively. This requires internet access.

12. 3D Cube Desktop
Useful for entertainment and inviting people to use same OS like yours. Enable it under System Settings > Desktop Effects > Cube > change the shortcut key to Win+S or anything else you like > Apply > play it.  Like example below when a student shows his Kubuntu to me via a Jitsi meeting.


That's all. I hope you enjoy it!

Fonts Use | Inkscape

Thursday 18th of February 2021 11:34:00 AM
After learning Open & Save, now we will learn about Fonts, before we learn about Making Text later. This Part III of the tutorial for students series discusses what are fonts, how we use fonts, and to get them to design & illustrate with Inkscape on computer. You will learn from here font families like Sans Serif Mono as well as their styles Bold Italic Regular aside from basic knowledge about fonts across operating systems with examples and pictures included. Happy learning and let's go!
Subscribe to UbuntuBuzz Telegram Channel to get article updates.[ In this series: Preamble | Part 1 | Part 2 | Part 3 ]

About Computer
To understand the rest of this simple tutorial, it is good to learn a little bit of computing. The main topic is computer -- it is an electronic machine which works with operating system (OS) otherwise it won't. In short, to display text on screen, computers use digital files --in fact, a certain type of programs-- called fonts, that styles how a b c ... z being drawn on screen.



By OS, it is a choice between GNU/Linux - Windows - macOS. By fonts, it is like applications, there are so many fonts (sometimes called typefaces) such as Times New Roman or Liberation Serif, they can be copied and used between different OSes. You obtain new fonts as files with a certain format, .ttf and .otf are the most popular ones, either from your friends or by downloading from the internet.

A user sees choice of fonts on his computer via programs, mainly a word processor (like Writer), or an illustrator (like Inkscape), or file manager (like Nautilus).

A Font
Fonts are choices and shapes.  Fonts (also called typefaces) are a part of computer operating systems (OS). Talking about fonts always involves a talk about OS choices. An OS brings its own fonts and will be different to other OS’ fonts for a user. For a user of Windows OS, you’ll be accustomed to these names – Arial, Courier, and Times New Roman. For a user of GNU/Linux OS, instead, you’ll know Liberation, DejaVu, and Free. A font consists of alphabets, numbers, and other characters in certain shapes. Every font is a file stored in a folder and used to draw text on screen. Fonts are the shapes of those text. Choices of fonts are choices of text shapes. Fonts are universal so they can be stored, copied, and used across OS choices – so you can use Arial on GNU and Liberation on Windows for example. Thus, a font is a collection of letters - numbers – characters drawn in certain style of shapes Bold - Italic - Regular which can be used repeatedly to produce text with computer. 

Types of Font
Serif, Sans, and Mono families are three kinds of font.

The particularity of Serif family is they are sharp. Look at the tips of every letter. Examples of Serif family fonts:
    • Times New Roman
    • Liberation Serif
    • FreeSerif
    • DejaVu Serif 


The particularity of Sans family is they are dull. They do not have “serif” and thus the name “sans-serif” meaning “without-sharp tips”. Examples of Sans family fonts:
    • Arial
    • Liberation Sans
    • FreeSans
    • DejaVu Sans 

The particularity of Mono family is they are square. Pick a letter and you will see the width and the length are equal – so are other letters. Seeing text in Mono fonts is like seeing text typed with the old typewriter machines. Examples of Mono family fonts:
    • Monospace
    • Courier New
    • Liberation Mono
    • DejaVu Mono
    • FreeMono 

Styles of a Font
Every font has some set of styles a computer user can choose. An excellent example is Ubuntu or DejaVu font with the most complete style choices. However, most fonts usually only have the first three styles. They are:
 - RegularThe default choice.
- BoldThicker text.
- ItalicLeaner text.- CondensedThinner text, narrower letter's width.
- LightThinner text, smaller letter's stroke.- Bold Italic, Condensed Bold, Condensed ItalicCombinations of available styles.

Sizes of a Font
A font supports multiple size. This makes computer can resize enlarge or shrink text very easily. To change a text size from one to another, thanks to fonts, a user clicks whatever size he wants on the computer and it changed. Below is my name typed with a Sans font with five different size (8, 10, 12, 15, and 20 points).

OSes and Their Fonts

Computer OSes bring some fonts by default and a user can add more if he wishes. You are good to know this as different OS creates different traditions or habits to the users because of their default fonts. What you need to know is that fonts are universal so ones from an OS can be used in the other OSes and vice versa -- that means Arial can be used on GNU/Linux, Liberation can be used on Windows, and vice versa, so does with Apple Garamond from MacOS. Below is OSes and their default fonts: - Windows: Arial, Comic Sans, Helvetica, Times New Roman
- GNU/Linux: Liberation, DejaVu, FreeFont- MacOS: Apple Garamond, Lucida Grande, Andale Mono

Where to get more fonts? 

 

Getting more fonts is as easy as copying some files to computer. Among the ways to get them:

- Ask your friends for copies
- GNU FreeFont 
- Liberation Font
- Libertine Font
- Ubuntu Font
- Comfortaa Font 
- Dafont.com


How To Install A Font
Fonts are installed on your OS, not in your application. A font is a stored file with the extension .ttf or .otf. To install one, double-click a font file and press Install button. Once a font has been installed on your OS, you can use them on Inkscape.


See a Font In Inkscape,  enable Text Tool (T) and font selector will appear on the toolbar.  Click the font selector drop down and selections of font with their examples will appear.
Use a Font To use a font is to benefit from its shapes. Once a font is installed, you can type text in Inkscape with that font with its choices of shape (Bold - Italic - Regular)
To apply a font to a text, first select the letters in the text with Text Tool then select a font from the selector. To add more fonts to Inkscape, is to add them to the operating system (OS). See above to do it. Summary That's all. From this part, you learned about what is font, a brief explanation about computing and OS, understanding font families and their particularities, and of course how to get and use fonts in computer graphic design with Inkscape. Next time, according to our table of contents, we will learn to text -- do the basics of dealings with alphabets, letters, numbers, and everything else of writings. Enjoy learning and see you in the next part!

8. Calls

 

Calls are divided to voice - video - screen sharing. 

  • To call a friend, simply click the phone button beside his/her name and wait for the acceptance. 
  • To call with a video, instead of the phone button, click the camera button and when he/she accepts it both of you will see each other's face. This requires webcams.
  • To call with screen sharing, that is, your screen appears on his/her screen and vice versa, first do a video call and then click the Screen button and select Entire Screen. 
You can kill webcam by clicking the camera button so the camera got a slash line.
 Notes: at the moment, Movim can do these 3 things only for 2 persons at a time (no conference) and the screen sharing is not working on Android. We all wish the best improvements soon appear at Movim. I can confirm the official Movim app for Android from F-Droid today is unable to do screen sharing and using Firefox Mobile is a better experience.

8. File Sharing With Movim you can upload photos, screenshots, documents, programs, and any other type of files to your friends.  To share a file, enter a chat > click PLUS button > Upload > a file chooser dialog appears > select one file > Share > the file sent to your friend. Note: at the moment, Movim can share one file per upload and no multiple upload or multi files drag-and-drop either (unlike Telegram's). We wish it will be added soon by the developers. 
Summaries

 

We are happy with Movim --the easiest Xmpp chat-- today. To sum up everything, it offers us all:

  • Free software & gratis access.
  • Friends, group chat and blogging in one place.
  • Video, voice calls with 2-ways screen sharing.
  • Web, desktop and smartphone supports.
  • Front & back cameras support for phone. 
  • and many more!
 My comments are like the following. I as a Telegram user --who also explore others-- feel Movim is good for most people (casual persons). We all can access Movim completely without phone number (advantage over Telegram) and the use is truly easy (advantage over Element) and the messaging is reliable (advantage over Jami). Some features are not present at the moment but they are acceptable considering it is highly potential thanks to Xmpp as its underlying technology. Finally, in the alternative world, I believe, people who felt satisfied with Mastodon will feel Movim satisfying too. That's all and happy chatting!

Formats to Save:

  • PNG
  • PDF
  • PostScript
  • EPS

 

 

Default format:

Inkscape as a computer program has its own graphic document format which is called scalable vector graphics (SVG). SVG to Inkscape is like AI to Adobe Illustrator and CDR to CorelDRAW. When you drew and saved a document in Inkscape, by default it is in SVG graphic format. This SVG format has many benefits and among them is it is widely accessible by any computer user with graphics or web browser programs. For example, you will see SVG is the format of many logos of many articles on Wikipedia -- you can download them and open them in Inkscape.


Open and Save
 
  • To open a graphic document, click menu File > Open.
  • An Open File dialog will appear.
  • Click the file and click Open button.

  • Security phrase is different to password and different to key.
  • Security phrase and key are better created on desktop.
  • You need a password manager app like KeePassXC.

Final goals should look like below that means everything is okay and verified.

 (Results wished from practicing this tutorial)


1. Do not have Element?

Register freely at Element.io and download the Android app on F-Droid. This is already explained in Element Basic Guide.


2. Do not have a password manager?

Get KeePassXC. Follow this tutorial to setup one. Run it and save your pair of Element username password as an entry on it. This is also explained already in KeePassXC Basic Guide. For Android, install KeePassDX from F-Droid as it can reads XC's database.


3. First Login

Do your first login on desktop. Go to app.element.io and login. If you do not know how, learn it at Element Basic Guide. Once logged in, you see the first welcome message.


4. Setup Security Phrase and Key

Go to menu > Security & Privacy > Secure Backup > Setup > Set up secure backup dialog appears > Choose Enter a security phrase > generate a pass phrase with your KeePassXC password manager > copy and paste that pass phrase to Element > Continue > copy paste it once again to confirm > Save Your Security Key appears after your Security Key has been generated automatically > download it, save the file named recovery-key.txt in KeePassXC app > Continue > finished. Now, you have an Element password, a Security Phrase, and a Security Key, and finally once you have these guys everything will be easy. Important: make sure you saved them all in KeePassXC and never lost them.

When Element asks you Security Phrase, open KeePassXC, and copy-paste it.

5. Verify Other Sessions

While Element Desktop is still active, now we will login from the second device that is a Element Mobile (Android or iOS). Open Element Mobile > login with your username and password > a notification appears on desktop "New login. Was this you? Later | Verify" > same notification also appears on phone > click Verify on both devices > desktop will show two verification options, either it is QR Code or Emojis > select QR Code > a QR Code appears on desktop > scan it with your phone > click verify on both devices > done. 

Alternatively, if you cannot scan QR (perhaps your camera won't work), you still can verify by Emoji. When the verification choices appear, select Emoji, a set of cute Emojis will appear on both devices > click They match on both devices > verified > done.


Conversely, you can do Desktop Login after Phone Login above, and the methods are just the same.

Important: for your convenience, it is better if your Element Mobile (Android or iOS) to be always logged in and never logged out.

6. Trust a Device

Once you logged in with multiple devices, you may be asked to verify the other device. Element can be used just fine without this but you can do it if you want. This is a security that is good for us. When you encounter this, as long as you had Security Phrase on your hands, everything is easy as follows:

On desktop:

Click your profile photo / avatar > Security & Privacy > click Verify Them > your profile appears > under Security section, you should find green devices marked TRUSTED > if not, click it > Verify > a notification appears on Element Mobile > verify it either with QR or Emoji > done. 

On phone:

Click your profile photo > Settings > Security & Privacy > Active Sessions > Show All Sessions > you should see all devices marked green and trusted > if not, verify it like above either with QR or Emoji > done.


 When Element asks for Security Phrase, open your KeePassXC, and copy-paste it.

7. Verify This Login

Desktop Login, that is a login done when phone is already logging in, will ask to Verify This Login. Steps to do so: make sure phone is logged in first > go to desktop > login > Verify This Login appears asking for another device verification > a notification appears on phone > tap it > now on the desktop the two choices, QR and Emoji, appear > verify it like explained above > done.


8. When to skip verification?

Element can be used just fine with skipping verification. When you need to skip? When both devices are logged out, then either one (much easier if it is desktop) wants to login, select SKIP and continue to Element. Once a device logged in successfully, now you can verify both like explained above. 


When Element asks you Security Phrase, open KeePassXC, and just copy-paste it.

That's all. Hopefully this will be useful to you!

  • United Nations Whisteblower Says The Tor Anonymity Network Is Great For Human Rights Work

    US military subsidiaries such as the NSA, who use Tor for open source intelligence gathering, are not the only ones who need a secure traffic analysis resistant anonymity network like Tor. UN human rights lawyer Emma Reilly says it is "great" when working with human rights defenders. [...] We feel for her, she is not the only one who was forced to learn Pascal in her youth. We also feel for all the victims of the UN Human Rights Council who has been handing over names of human rights activists from the day it formed in March 2006. China is not only having a very negative impact on human rights activists who contact the UN for help, China is also committing grave crimes against pro-democracy activists in Hong Kong (香港). [...] The free software tool OnionShare is a very user-friendly program that lets you share files and setup chat-rooms over the Tor network in case you need to communicate with human rights activists or other endangered people in a secure fashion. You can follow human rights lawyer Emma Reilly on Twitter if you want to learn more about her important human rights work. She does not appear to have a fediverse social media account in case Twitter de-platforms her on behest of the Chinese regime.

  • How one woman fired up her online business during the pandemic

    Sophia Keys started her ceramics business, Apricity Ceramics, five years ago. But it wasn’t until a global pandemic forced everyone to sign on at home and Screen Time Report Scaries became a thing that her business really took off. She had never been active on social media, but decided to create relaxing videos of pottery throwing as a type of craft-ASMR (autonomous sensory meridian response videos that provide relaxation with a sedative, tingling sensation for some) early in the pandemic. These videos gained traction and Keys started building a community. A couple months into the pandemic, when she had more finished pieces than she knew what to do with, she posted about the sale on her Instagram page. She sold out. She now has over 21K followers and her ceramics sell out in hours. Amidst the chaos of 2020, here’s how Sophia expanded her woman-owned online business, found her own confidence on social media, and built a community around her handmade products.

Games: Assassin’s Greed, Yorg, Wanted Raccoon and More

  • Assassin’s Greed

    I don’t think any sane person is going to disagree with the quote, “Power corrupts; absolute power corrupts absolutely.” For those unaware, that quote came from British politician Baron Acton in 1887. That’s one of the few sayings man has uttered that stands against the test of time. Keep in mind, Acton coined this phrase from politicians who said something similar even earlier than his time; Acton’s phrase just seems to be the most popular, since it reads like modern English. Now, I’m not trying to get into politics; we’re a gaming web site, after all. But sadly, after a number of events have occurred — for the gaming industry in particular — within the past couple of years, I feel like even us Linux gamers get the short end of the stick. True, we always had the short end of the stick, up until Valve stepped in and basically saved our bacon around 2012-2013. But as far as native Linux games are concerned, and as advanced as Proton gets, competition that has arisen lately can either be a plus for us, or, as I bring out here, competition can be more so of a nuisance than it is anything else. [...] Yeah, some were probably expecting me to point the gun at Microsoft first. I’m not a total Microsoft hater, as I do appreciate some of their work, like some of the code they’ve contributed to the Linux kernel. But I seem to hear it all the time. Microsoft bought this company. [...] Microsoft joined the Linux foundation late 2016. Supposedly, they’re a high-paying “Platinum Member.” I don’t know if their claim, “We love Linux,” is actually true. If anything, they consider Linux as a threat, as long as they’re not making revenue via this platform. They haven’t made any official drivers for Linux as far as their Xbox controllers are concerned. Microsoft is invested in Linux at least when it comes to their whole Azure cloud services, a competitor to AWS and Google Cloud, and they have made it easier to develop for Linux within Windows with the WSL module developed in partnership with Ubuntu. Microsoft tried to make their own locked garden during the Windows 8 era with the Windows Store and trying to force everyone to put their applications through there. Fortunately, they failed miserably, thanks in no small part to Valve creating SteamOS. But it doesn’t mean Microsoft won’t stop trying.

  • FOSS racer Yorg has a new release with improved gamepad support | GamingOnLinux

    Top-down open-source racing? Yorg is a little bit like some of the classic Micro Machines games and while rough around the edges as it's in development it's showing promise as another FOSS game. With fast arcade racing along with some amusing physics, Yorg is already a lot of fun with multiple tracks, vehicles and different drivers to pick from. You can play against AI, local multiplayer and experimental online multiplayer. There's weapons too, so you can blow everyone up.

  • Wanted Raccoon is an upcoming comedy game in the spirit of Goat Simulator

    Remember the craziness of Goat Simulator? Wanted Raccoon has a familiar theme of animals going wild and it's entering Early Access on March 19 with Linux support. A game that seems like a big gimmick but apparently there's a little more to it. The developer mentions an actual storyline and some sort of research system. You can ride skateboards, fight people, upgrade skills, and of course - steal food. Everything a good Raccoon does right? There's also something about a kidnapped family. Hero Raccoon to the rescue?

  • Building a Retro Linux Gaming Computer - Part 2: Selecting a Graphics Card

    Linux graphics support is still remarkably similar to how it was 20 years ago, even with all the progress that has been made in the years since. The Mesa 3D graphics library had its origins all the way back in 1995, and through the Utah GLX project attracted the attention of industry luminaries such as id Software’s John Carmack and vendors such as ATI, Intel, Matrox, S3, and 3dfx. By the turn of the millennium all of them had at least some support in Mesa. Nvidia went a different route, one which continues to set them apart to this day. Rather than choosing to cooperate with Mesa they instead ported their Windows drivers over to Linux directly, maintaining their own proprietary binary blob separate from the main Linux kernel. This driver model was also later adopted by ATI when they switched focus to their own proprietary “fglrx” driver, although this was largely reversed again after AMD acquired the company in 2006. By the time of Red Hat Linux 9 the Direct Rendering Infrastructure or DRI was firmly in place in Mesa and offered 3D support for a wide number of cards. This included the ATI 3D Rage Pro Turbo, which was the AGP card I had selected to test the machine. While a solid 2D performer it offered lacklustre 3D graphics even for the time of its release, and was intended more as an OEM graphics solution than for gaming. That makes them easy to find, but also not worth a lot.

10 Best Compression Tools for Linux

  • Server Security Tips – Secure Your Server with These Best Practices

    Servers play a vital role in organizations. Their primary function is to provide both data and computational services. Because of the critical role they play, servers hold confidential organizational data and information. Information is like gold nowadays, and hackers are gold miners. An insecure server is vulnerable to all sorts of security threats and data breaches.

    Fortunately, before any active exploitation, Popov fixed these bugs for the users. Popov has confirmed merging of these patches with the mainline kernel version 5.11-rc7. Also, the fixes have been “backported into the stable affected trees”. As Positive Technologies elaborated, this isn’t the first time Popov found and patched a vulnerability. Earlier, he has also caught and fixed two Linux, bugs CVE-2017-2636 and CVE-2019-18683, as well in 2017 and 2020 respectively.

  • Understanding Samsung Knox Vault: Protecting the data that matters most

    Eight years ago, Samsung set out on a mission to build the most trusted and secure mobile devices in the world. With the introduction of our Samsung Knox platform at MWC in 2013, we put in place the key elements of hardware-based security that would help defend Samsung mobile devices and our customers’ data against increasingly sophisticated cyber threats. Samsung Knox has since evolved into more than a built-in security platform, now encompassing a full suite of mobile management tools for enterprise IT administrators. But our mobile product planners, developers and security engineers have remained laser-focused on answering the primary question: how do we remain a step ahead of hackers and keep our users safe at all times? [...] In the first days of Android, the main focus was building a more open and flexible mobile operating system. Security was state-of-the-art for the time, inherited from the world of Unix and mainframe computers. But from the start, it became clear that smartphones were different; they were the most personal computers anyone had ever built.
