Types of operating systems.

Operating systems normally include pre-loaded on almost any Computer you purchase. Many men and women use the operating system which comes with their computer, however it is possible to update or perhaps alter operating systems. The three most frequent operating systems for personal computers are Microsoft Windows, macOS, and Linux. A GUI enables you to use your mouse to click on icons, switches , and menus, and that which is clearly displayed on the display by means of a combo of images and text. Each operating system's GUI includes a different feel and look, so if you Switch to another operating system it might appear unfamiliar at first. However, modern operating systems have been made to be effortless to utilize , and the majority of the fundamental principles are exactly the same.

Microsoft established the Windows operating platform at the mid-1980s. There have been a number of distinct variants of Windows, but the latest ones are Windows 10 (published in 2015), Windows 8 (2012), Windows 7 (2009), along with Windows Vista (2007). Windows includes pre-loaded on many new PCs, which helps to ensure it is the hottest operating system on the planet.

MacOS (formerly called OS X) is a Lineup of operating systems made by Apple. It comes preloaded on all Macintosh computers, or Macs. A number of the specific models include Mojave (published in 2018), High Sierra (2017), and Sierra (2016). Based on StatCounter Global Stats, macOS users accounts for significantly less than 10 percent of international functioning systems--considerably lower than the percent of Windows users (greater than 80 percent ). 1 reason behind this is that Apple computers have a tendency to be costlier. But a lot of individuals do prefer the appearance and feel of macOS over Windows.

Linux (pronounced LINN-ux) is a household of open-source operating systems, so they may be altered and distributed by all around the globe. This differs from proprietary program such as Windows, which may only be altered by the organization that owns it. The benefits of Linux are that it's free, and there are several different distributions or variations you may select from. Based on StatCounter Global Stats, Linux users accounts for under 2 percent of international functioning systems. But most servers run Linux since it's relatively simple to personalize.

The operating systems we have been speaking about so much were created to operate on desktop and notebook computers. Mobile apparatus like telephones , tablets , and MP3 players Are distinct from desktop and notebook computers, so that they run operating systems that have been designed especially for mobile devices. From the screenshot below, you can view iOS running in an iPad. Operating systems for mobile devices normally are not as fully featured As those created for desktop and notebook computers, and they are not capable to Run each the exact same software. But, you can still perform a Great Deal of things Together, like watch videos, browse the net, manage your calendarand play games.

Simos Xenitellis: Using ibus-typing-booster for predictive typing in Ubuntu 20.04 LTS

Ubuntu 20.04 LTS has switched to using the IBus input framework for most (all?) languages, even those based on the Latin, Cyrillic or Greek scripts. Typing in English is not that demanding for your operating system; there is a one to one association between the key you press, and the result you see on your screen. But if you have to type accents, or type in some more complex script, then you need a more advanced input framework.

You wouldn’t notice a difference when typing on Ubuntu 20.04, unless your language has accents and when you type, you press special key combinations to add those accents. For example, «αηδόνι». Notice the accent on the «ο». When you type the accent and then the «ο», you get visual information on the imminent composition of «ό».

Typing in Greek on Ubuntu 20.04. Input is handled by IBus, and by default we can see visually the addition of the accents while typing.

But is it worth the effort to switch to something more complex when the old way used to work just fine? That’s a perennial question. My view is that once you switch to an input framework, you can do much more advanced and exciting things. This post is about using the ibus-typing-booster...

My view is that once you switch to an input framework, you can do much more advanced and exciting things. This post is about using the ibus-typing-booster plugin to IBus that adds predictive typing to the Linux desktop. Oh, you can also type emoji easily. 👍

Installing ibus-typing-booster to Ubuntu 20.04

Gunnar Hjalmarsson maintains a package at the ibus-typing-booster PPA. Follow the instructions to install on Ubuntu 20.04 LTS, for now. Gunnar has uploaded the package on Debian’s NEW queue and it is just a matter of months for the package to get accepted.

sudo add-apt-repository ppa:gunnarhj/ibus-typing-booster
sudo apt-get update
sudo apt-get install ibus-typing-booster

Then, log out and log in into Ubuntu 20.04. A reboot is good as well.

Configuring ibus-typing-booster in Ubuntu 20.04

We are adding the layout for the ibus-typing-booster to Ubuntu 20.04.

Go to Settings and click on Region & Language.You will see the current keyboard layouts (above the red arrow). There are two here, English (US) and Greek. Click on the + sign to add a new one.
We are adding a different layout from the existing English and Greek layouts. Therefore, click on those three vertical dots to open up adding other layouts.
The three vertical dots expand, and the list becomes somewhat longer, still covering any layout based on the two main language on my setup, English and Greek layouts. Still, click on Other as shown with the red arrow.
The list becomes bigger, therefore perform a search at the bottom of the window. Search for “typing”, in order to see “Other (Typing Booster)” in the list. Click to select it.
We have clicked to select it. And we can click on the green button that adds it to our system.
We have added the Typing Booster input method. In this setup, I have English (US), Greek and “Other (Typing Booster)”.
We can see Typing Booster in the keyboard layout applet. We are set to go.

We have configured the Typing Booster and are ready to start typing.

Using the Typing Booster

When you switch to the Typing Booster input method, you are boosting the last keyboard layout that you had selected. This previous sentence was the most important one in this whole post.

You can still use your existing keyboard layouts as normal, but if you want to boost one of them, them switch from that keyboard layout to the Typing Booster input method. The keyboard layout is then boosted, until you switch out of the Typing Booster.

We type using completion, i.e. predictive typing. As we type, there are candidates, which we may select instead of typing the whole thing.

Selecting a candidate can be done in several ways,

  1. Using the mouse.
  2. Using the arrow keys.
  3. Pressing the number of the candidate in the list.
  4. Pressing the corresponding function keys (F1 for 1, F2 for 2, etc).

Conclusion

The Typing Booster has many settings and can do many things. I think the important aspect is to use it and get used to using it. Initially it might be awkward when you type. But as you type more, the Typing Booster learns the words you are typing and becomes from intelligent in suggesting better candidates.

As soon as Gunnar’s package gets promoted out of the NEW queue, the package will make it into the universe repository and will be available to all. If you know someone that can look into the this, point them at the URL above.
