Computer Practice N4 App

[Baudilio Eliason]

Acomputer is more than just another household appliance. The vast amount of information and possibilities can be overwhelming. But you can accomplish a lot with a computer, and using one can be a good experience. Let's walk through getting started with your first computer.

The very first step is to turn on the computer. Make sure all the cables are plugged in correctly, and locate the power button. It's in a different place on every computer, but it will have the universal power button symbol (shown below).

Once turned on, your computer takes time before it's ready to use. You may see a few different displays flash on the screen. This process is called booting up, and it can take anywhere from 15 seconds to several minutes.

Once the computer has booted up, it may be ready to use, or it may require you to log in. This means identifying yourself by typing your user name or selecting your profile, then typing your password. If you've never logged in to your computer before, you may need to create an account.

You interact with a computer mainly by using the keyboard and mouse, or a trackpad on laptops. Learning to use these devices is essential to learning to use a computer. Most people find it comfortable to place the keyboard on the desk directly in front of them and the mouse to one side of the keyboard.

The mouse controls the pointer on the screen. Whenever you move the mouse across the desk, the pointer will move in a similar manner. A mouse usually has two buttons, which are referred to as the left button and the right button. You will often interact with the computer by moving the mouse pointer over something on the computer screen, then clicking one of the buttons.

On laptops, you can use the trackpad, located below the keyboard, instead of a mouse. Simply drag your finger across the trackpad to move the pointer on the screen. Some trackpads do not have buttons, so you'll either press or tap the trackpad to click.

The main screen you'll start from is the desktop. This is sort of like a main menu or a table of contents. From here, you can access the programs and features you need to use your computer.

Icons are used to represent the different files, applications, and commands on your computer. An icon is a small image that's intended to give you an idea at a glance of what it represents, like a logo. Double-clicking an icon on the desktop will open that application or file.

Menus are organized collections of commands and shortcuts. Click a menu to open it and display the commands and shortcuts within. Then click an item in the menu to execute it.

Now that you've learned how to turn on your computer and interact with it, take time to become familiar with these skills. When you're ready, check out our other topics to learn more. You can build on this foundation and learn how to do whatever you want with your computer.

Is there a way to set up the computer player (on the web site or app) so it plays using only a certain opening style (as white)? Or is there a chess app elsewhere that does something similar? This way I should be able to repetitively put into practice the principles I've been learning. Well, that's the idea anyway.

Good question but hard for me to answer as I'm a beginner. I think I'm just talking about common openings and attacks that would challenge a beginner but would be confidently handled by a more experienced player. Maybe setting the computer level low has this effect?

Of course over time I would learn openings and their "lines" just by playing games, but I feel being able to limit the computer to specific openings provides useful repetition which is a more efficient way for me to learn.

Thats what im talking about. You want a "style" but you dont know how to answer the question. As a beginner you dont want to limit what your opponent will play. The more youre exposed to, the more youll learn.

If u want to play against the computer in a specific opening line you can do it with Lucas Chess. Here's how--1. Click desktop icon. 2. Click Play 3. Click play against an engine of your choice. 4. Click Initial Moves. 5. Find your variation in Game Explorer on this website and copy fen. 6. Click Initial Moves. 7. Click clipboard Icon. 8. Click accept.

If you want to play against a specific style such as a tactical style or positional style you need to find a specific engine that has a reputation for playing in that style. This may take some research.

@Diakonia: Yes, exactly. I need to work on my openings and development. That's why I'd like to use the computer player (rather than waste a real player's time) to practice all the principles... but in a way that is more focused. (Thanks for the game analysis. That's pretty cool)

Yeah well I understand him just fine. If you want to practice e.g. Queen's Gambit Declined, but CPU keeps accepting the gambit, you keep getting into another line. Yes you can edit the board starting position, but it's not the same. People like havelock3 and myself want to try to learn a certain opening variation by practicing the moves. If the CPU plays different moves each time it makes practicing more difficult.

For future people searching this, I think this is the way it's done. Hover on "Learn" on the left dashboard column, then another dropdown menu comes up, select "Openings." You can practice whatever opening they have there. Should be common ones with e4, d4, and "other," but if you're looking for something specific type your opening into the "search" box. Click the opening you want and it will bring up the position. To practice with this position click the computer looking icon (as of 2021 it looks like a laptop, actually).

The only problem that I can't figure out is how to change the difficulty of the computer. It's set on 3200, which is so insanely high. I came in search of this feature and can't find it. Any help would be appreciated. Not exactly intuitive to find the settings to change here.

One sneaky way of accomplishing the any opening vs any bot is to set up the first however many moves of the position you want to practice on the setup/analyze board, then chose "play against a computer", then change to the bot you want to practice against. This works twice because you get the specific opening and position you want to practice with, AND you can have the computer telling you what move you could have played as the game goes on.

I will probably buy a new laptop, probably Pop!_OS pre-installed, in the next several months. Thinking ahead I am trying to mentally rehearse how to reconstitute my home directory (Pop 22.04). I back up only from $HOME with some exclusions, and I do not expect to need everything on my new device (unless it is just easier to do a complete $HOME restore).

Are there best practices for something like this? When I have restored a single file or folder in the past, I usually use the mount command followed by cp. However, I am thinking that would not be the most efficient for the entire $HOME. Also, my new laptop will already have a user and home/[user] with my name. Is restore to a tmp directory the answer? What have some expert users done in this situation?

Your mistake was to run init on the second host. init is for creating a repository. What you have effectively done is created two different master keys in the same repository which, to my knowledge, is unsupported. Because the master keys differ, neither host would be able to decrypt objects added by the other host.

And even this is not needed. I would actually not use it. What will happen is that first backup from new machine will take a bit longer as all files will be fully read/hashed/compared with stored data. If they are already in repo nothing new will be backed up anyway (but some metadata). Then subsequent backups will be as fast as before.

A single data loss incident can cause hundreds or even thousands of critically important files to disappear. Unfortunately, their recovery may not be possible even with professional data recovery services.

There are two types of customers all car mechanics dread. Teenagers who modify their vehicles without much common sense, and messy people who use their car as their trash bin. Computer users often do both things on their devices without even realizing it.

Public Wi-Fi networks can be extremely convenient. After all, they give you internet access in a place where you may not be able to obtain it. Their convenience comes at a price, however. And this price is your security and privacy.

Bonus Tip: Also avoid using USB charging ports in public spaces. These are also being used by hackers to introduce malware and monitoring software onto your device. This attack technique is called juice jacking.
