Introduction to Krita Stabilizer

Krita Stabilizer is the most important feature of this software, and by enabling this feature, we can provide smoothing to our brush stroke. There are some parameters also with this feature that are adjustable, and by adjusting them, we can make a variation in the smoothing quality of brush stroke. You have noticed many times that when you start to draw your raster artwork in Krita, you faced a smoothing problem in brush strokes. There is a couple of things for this issue, and you can short out these things by following some designing technique in this software.

How to Use Stabilizer in Krita?

A stabilizer actually works as a smoothing agent for brush stroke. Now let me tell you why you need to smooth brush stroke and what happens when we do it?

Now go to the tool panel, which is on the left side of the working screen and select Freehand Brush Tool or press the B button of the keyboard as the shortcut key of it.

Choose your desired brush preset from here. I will take a basic brush preset to explain to you about the stabilizer feature.

Set size of the brush as 10 pixels from this Size option.

You can also set the size of the brush tip from Edit Brush presets dialog box. Just give your desired value in the Diameter option of the chosen brush.

Now draw a line with this brush.

And zoom it at 100%. You can see there is jazziness in this line, and it is not smooth. Due to this issue, your artwork may look blurry, which is not good for you.

Now the canvas size is very big. Draw a line with the same brush preset parameters, which we used last time in an 800 x 800 pixels document.

When you zoom in, you can see only 100% zoom; it is much smoother than the previous one. So I will suggest you take a bigger size of document for your artwork in Krita software. Document size below 1000 x 1000 pixels will act as a baby size for your artwork, and you will not get your desired result.

And draw a line you can see it is lots of jazziness in it.

For having more smoothness in line, we can do a couple of things, such as we can use smoothing settings in the brush. Here on the right side of the working screen, you will have the Tool options tab, and in this tab, we have Brush Smoothing options.

Let me tell you about these options one by one. First is will select a Basic option and draw a line next to the previous line, which I have drawn with the None option of Brush Smoothing.

One more time, draw a line, but this time select the Stabilizer option of this list, and you can find a difference between each option. With the Stabilizer option, you will have a smoother line than all of the options. Here when you select the stabilizer option, the mouse cursor will change into two circles; tip like that and out circle represents delay time during drawing with it.

Delay can be understood as controlling the speed of drawing any stroke that means when the value of delay is less, then the stabilizer will provide less stoppage in drawing any stroke, or if delay value is more, then there will be more stoppage during drawing and speed of drawing that stroke becomes slow. Due to slow speed, there will be good smoothness on any stroke.

For example, if I draw this curve with less value of delay, it will be less smooth.

And if I increased the delay value, then you can see it is smoother than the last one.


Now you can understand how important a Stabilizer is in Krita? You can use this feature of Krita to have a good quality of the result of your art work. It is easy to handle it because it offers adjustable parameters for dealing with our different requirements. I am sure it will be a very helpful feature to your art work in Krita.

Learn How To Use Boolean Operators In Matlab

Introduction to Matlab boolean

MATLAB Boolean operators are used to return logical values (True for 1 and False for 0) in case we want to check if a condition is met or not. Boolean operators are very useful in codes where we need to execute code lines based on certain conditions.

Start Your Free Data Science Course

Hadoop, Data Science, Statistics & others

For example, we can compare 2 numbers using logical operators and get True in the output if the numbers are equal else False.


How to use Matlab boolean with Examples?

Let us now understand how to use logical or Boolean operators in MATLAB. We will discuss 2 scenarios:

The use of Boolean operators in arrays

The use of Boolean operators in circuits

Example #1

In this example, we will use an ‘&’ operator between 2 matrices. An ‘&’ operator will give ‘1’ as the output if the corresponding elements in both the matrices are non-zero, else it will give ‘0’ as the output. The steps to be followed for this example are:

Initialize the input matrices

Use the ‘&’ operator between the matrices


A = [5 4 1; 5 2 0; 1 0 1] [Initializing the 1st matrix] B = [0 1 1; 0 0 0; 1 9 3] [Initializing the 2nd matrix] [Using the Boolean operator ‘&’ between the matrices. The output will be a matrix of 0s and 1s]

This is how our input and output will look like in MATLAB:


A = [5 4 1; 5 2 0; 1 0 1] B = [0 1 1; 0 0 0; 1 9 3] A & B


As we can see in the output, the Boolean operator ‘&’ gives ‘1’ as the output if the corresponding elements in both the matrices are non-zero, else it gives ‘0’ as the output

Next, we will see the use of the ‘&’ operator in the circuits

Example #2

When used in circuits, the ‘&’ operator will give ‘1’ as the output if both the variables are non-zero, else it will give ‘0’ as the output. The steps to be followed for this example are:

Initialize the input variables

Use the if-else loop along with the Boolean ‘&’ operator


[Initializing the 1st variable] [Initializing the 2nd variable] [Initializing the 3rd variable] [This loop with Boolean ‘&’ operator will check if both the variables are non-zero; In this example we have taken both ‘a’ and ‘b’ as non-zero] [This loop will check if both the variables ‘a’ and ‘c’ are non-zero]

This is how our input and output will look like in MATLAB:



In the 1st loop, both the variables ‘a’ and ‘b’ are non-zero, so the output after using Boolean ‘&’ operator is “Both the numbers are non-zero”

In the 2nd loop, the variables ‘a’ is non-zero, whereas the variable ‘c’ is zero, so the output after using Boolean ‘&’ operator is “Both the numbers are not non-zero”

Example #3

Initialize the input matrices


A = [2 4 6; 2 2 0; 3 0 7] [Initializing the 1st matrix] B = [0 4 1; 1 0 0; 2 0 3] [Initializing the 2nd matrix]

This is how our input and output will look like in MATLAB:


A = [2 4 6; 2 2 0; 3 0 7] B = [0 4 1; 1 0 0; 2 0 3]


Example #4

Initialize the input variables


[Initializing the 1st variable] [Initializing the 2nd variable] [Initializing the 3rd variable] [Initializing the 4th variable] [This loop will check if one of the variables ‘c’ and ‘d’ is non-zero]

This is how our input and output will look like in MATLAB:





Boolean operators are useful in cases where we want to check if a condition is met or not.

Boolean operators are also used in circuit codes where we need to execute code lines based on certain conditions.

How To Install The Latest Version Of Krita In Ubuntu

You’ve updated and upgraded your Ubuntu installation, but Krita remains in its pre-4.3 version. That’s because Ubuntu’s official repositories don’t offer the latest and greatest from Krita’s developers. Let’s see how to install the latest version of Krita on Ubuntu.

Via Snap

It’s a well-known fact that Ubuntu’s latest version prioritizes snap over apt. Although apt insists on installing a pre-4.3 version of Krita, the latest one is available through snap. Terminal fans can install it with:





Those who prefer the visual way of doing things can bring it on-board through Ubuntu’s Software Center. Start by running the software center app, then typing Krita’s name in the top search field.

Via AppImage

Krita’s developers also offer their much-beloved graphics application in AppImage format. It’s almost as easy to install and use as the snap version but requires you to go over a series of steps until you can use it. Plus, you will have to update it manually in the future. Still, this is probably the most familiar way of installing software for former Windows users.

When the process completes, open the folder containing the downloaded file in your file browser.

If you have difficulty executing it, you can make use of the traditional way to make it executable. Open a terminal and type the following command:

Via Apt

Krita’s latest version might be missing from Ubuntu’s official repositories, but you can still access it via the developer repository.

Start by adding the third-party repository to Ubuntu’s list:


add-apt-repository ppa:kritalime



Acknowledge any prompt which may appear. After you have done so, update Ubuntu’s software list with:


apt update

Finally, install it with a typical:





With the latest version of Krita installed in your computer, it is now time to sketch like a pro with Krita. If Krita is not to your liking, you can also check out some of the best image-editing software for Linux here.

Learn How To Use A Kreg Jig To Make Pocket Holes

Sharing is caring!



Make pocket holes with ease using a kreg jig! This simple tool makes building furniture and woodworking projects so easy!

Whether you’re making a wood countertop or a mirror frame, the kreg jig is such a handy tool to have around.

When I bought my kreg jig, I had no idea how much I would love it. Sure, DIY bloggers everywhere sing it’s praises, but would I find it useful? After over 2 years of using it, I’ve found that I love it.

We used it to build our farmhouse table, the bar in our sunroom, a cabinet in our kitchen (that still needs to be finished) and countless other projects.

Over the weekend, we built a bathroom countertop, and as I worked on it, I felt it would be helpful to write a guide on using a kreg jig to make pocket holes.

Using a Kreg Jig FAQs About the Kreg R3 System

We bought ours without knowing how useful it would be, so we bought a smaller kit and a clamp. Even though it’s not the large kit, it gets the job done.

The kit comes with a sample pack of screws. So far, I haven’t found that other screws work with the kreg jig. I’m partial to deck screws when building, so this bums me out a lot.

What is a kreg jig?

A kreg jig is a pocket hole jig. It allows you to make pocket holes without much thought or fuss.

Pocket holes are holes that drilled at at angle and can be filled. The pocket holes turn out perfect every time with a kreg jig.

What are pocket holes?

Pocket holes are used to join 2 pieces of wood without visible screws. They can be used to join 2 pieces to make a flat surface (like a table top), or to join 2 pieces to form a perpendicular angle (like an L or a cube).

Pocket holes are the best way to join wood, in my opinion. You get a strong surface without using glue. 

Why would you want pocket holes?

A kreg jig is also very useful for joining smaller pieces of wood together to create one large piece (like a tabletop or countertop.) It creates a very strong joint, which is really important for furniture.

It’s also useful for joining corners, particularly when you’re using thinner or weaker wood that you wouldn’t want to screw straight into, like plywood.

Can you use regular screws with a Kreg Jig?

Unfortunately, no. You have to use the kreg jig brand screws because other screws don’t fit.

Luckily, the screws are good quality!

They remind me of my favorite deck screws because they have a smooth shaft that creates tighter joints.

How to Use a Kreg Jig R3 to Make Pocket Holes

Measure the thickness of your wood. My wood was 3/4″ thick. Don’t make assumptions here. If you buy a 1×4, it’s not a true 1″ x 4″. It’s typically about 3/4″ x 3 1/2″.

Cross reference the handy chart that comes in the book with your kit. It tells you the setting that you need for your kreg jig and the length of screws needed. You will use this chart every time you use it, so don’t lose it!

Adjust the drill bit to the correct depth based on the wood thickness. Use the allen wrench to loosen the depth collar and move it to the correct spot as indicated by the case. Then tighten it with the allen wrench. Mine needed to be 3/4″, so I moved it until the edge lined up with the 3/4″ mark.

Adjust the jig to the correct depth. Be sure to use the arrow and not the top line like I did by mistake! You will have to redrill all the holes. Push each side up or down until it’s in the right place. (This part took me forever to figure out.)

Clamp the jig in the right spot. For the countertop we were building, we placed it about 3″ from where we were going to cut it, and about every 6″ after that.

Attach the drill bit to your drill.

Drill the pocket holes using the jig. The jig has 2 holes, but I normally just choose one.

Repeat for all of your holes.

Screw the wood together. When you are finished drilling all of the holes, change the drill bit to the driver and screw in the right length of screws. The guide will tell you the right length. Be sure not to over-tighten because wood needs a little breathing room to expand. We used clamps to keep the wood nice and tight. 

Repeat for the rest of your holes.

You can see where I messed up and set the kreg jig using the top as the guide instead of the arrow. The correct length of screws would have been too short at this setting. Longer screws would poke through the beautiful top. Luckily, it doesn’t matter what the underneath of a countertop looks like!

Using a kreg jig is much easier than I ever imagined and it makes DIY projects look more professional. Now that you know how to use a kreg jig, you’ll be making beautiful projects in no time!

Have you ever used a kreg jig?

How To Use Pprint In Python?


Improve your Python output with the power of pprint! Properly formatted and visually appealing output can greatly enhance your code debugging experience. This article introduces pprint, a Python library that serves as a Data Pretty Printer. Whether you’re dealing with JSON files or working with dictionaries, pprint can help you handle large amounts of data more effectively. Say goodbye to messy outputs and confusing structures. Best of all, pprint is an inbuilt Python library, so no separate installation is required. Let’s dive in and make your outputs shine!

This article was published as a part of the Data Science Blogathon.

What is pprint()?

It stands for “Pretty Print”, and is one of the native Python libraries that allows you to customize your outputs with its numerous parameters and flags for its single class pprint(). Here is the official documentation to list all of its properties and usage.

pprint() Parameters

The library contains just a single class, called pprint(). There are in total six parameters that can be used with this class. Here is a short description of the parameters along with their default values:

indent: The number of spaces to indent each line, this value can help when specific formatting is needed. Default value = 1

width: Maximum characters that can be in a single line. If the number of words exceeds this limit, the remaining text will be wrapped on the lines below. Default value = 80

depth: The number of depth levels to be shown while using nested data types. By default, it shows all the data, but if specified, the data beyond the depth level is shown as a series of dots ( . . . ). Default value = None

stream: This is used to specify an output stream and is mainly used to pretty print a file. Its default behavior is to use sys.stdout. Default value = None

compact: This is a boolean argument. If set to True, it will consolidate complex data structures into single lines, within the specified width. If the value is the default (ie. False) all the items will be formatted on separate lines. Default value = False

sort_dicts: This is also a boolean argument. While printing dictionaries with pprint(), it prints the key-value pair sorted according to the key name alphabetically. When set to false, the key, value pairs will be displayed according to their order of insertion. Default value = True

Now enough with the technical stuff, let’s jump into the programming part!

Basics of pprint()

First, we import the pprint module at the beginning of our notebook.

import pprint

Now you can either use the pprint() method or instantiate your pprint object with PrettyPrinter().

Now let us create a sample dictionary to demonstrate some of the arguments of the class pprint().

sample_dict = { 'name': 'Sion', 'age': 21, 'message': 'Thank you for reading this article!', 'topic':'Python Libraries' }

If we simply print out this dictionary using print, what we get is:

{'name': 'Sion', 'age': 21, 'message': 'Thank you for reading this article!', 'topic': 'Python Libraries'}

Now that doesn’t look much appealing, does it? But still one might argue that this output format is okay since you can clearly see which value belongs to which key, but what happens if these values are extremely long, and nested. Or if the volume of our key-value pairs is much much more? That’s when it all goes downhill. It will become very very difficult to read, but worry not, print to the rescue:


Firstly, all the pairs have their separate row, which increases the readability tenfold. Also if you look closely, all the elements are automatically sorted according to the keys.

Text Wrapping

Most people might know the basics that I showed above. Now let’s use some of the other parameters to further customize our outputs.

Another basic usage is text wrapping. Suppose you are not satisfied by just printing the key-value pairs on separate lines, but want to have the text wrapped when the length of the line exceeds a certain amount. For this, we can use the width parameter.

pprint.pprint(sample_dict, width = 30)

Apart from this, we can use the indent parameter to add indentation in front of each row for better readability.

pprint.pprint(sample_dict, width = 30, indent = 10)

Here is an example for the usage of compact and width parameters:

import pprint stuff = ['spam', 'eggs', 'lumberjack', 'knights', 'ni'] stuff.insert(0, stuff[:]) pp = pprint.PrettyPrinter(indent=4) pp.pprint(stuff) pp = pprint.PrettyPrinter(width=41, compact=True) pp.pprint(stuff) Deep Nested Objects

Image Source: Missouri Dept. of Conservation

Sometimes while working with highly nested objects, we just want to view just the outer values and are not interested in the deeper levels. For example, if we have a nested tuple like this:

sample_tuple = ('spam', ('eggs', ('lumberjack', ('knights', ('ni', ('dead', ('parrot', ('fresh fruit',))))))))

Now if we use print or print, the outputs will be almost similar:

print(sample_tuple) > ('spam', ('eggs', ('lumberjack', ('knights', ('ni', ('dead', ('parrot', ('fresh fruit',)))))))) pp.pprint(sample_tuple)

However, if the depth parameter is specified, anything deeper than that will be truncated:

pprint.pprint(sample_tuple, depth=2) pprint.pprint(sample_tuple, depth=1) p = pprint.PrettyPrinter(depth=6) p.pprint(sample_tuple) pprint() vs PrettyPrinter()

The difference between these two is that the pprint() method uses the default arguments and settings of the libraries, which you can change like we previously saw, but these changes are temporary.

With PrettyPrinter(), you can create a class, with your own specifications and override the default settings to create permanent class objects which retain their forms and values all over your project.

import pprint coordinates = [ { "name": "Location 1", "gps": (29.008966, 111.573724) }, { "name": "Location 2", "gps": (40.1632626, 44.2935926) }, { "name": "Location 3", "gps": (29.476705, 121.869339) } ] pprint.pprint(coordinates, depth=1) > [{...}, {...}, {...}] pprint.pprint(coordinates)

As you can see, the arguments supplied were just temporary. Conversely, these settings are stored with PrettyPrinter(), and you can use them wherever in the code you want, without any change in functionality:

import pprint my_printer = pprint.PrettyPrinter(depth=1) coordinates = [ { "name": "Location 1", "gps": (29.008966, 111.573724) }, { "name": "Location 2", "gps": (40.1632626, 44.2935926) }, { "name": "Location 3", "gps": (29.476705, 121.869339) } ] my_printer.pprint(coordinates) > [{...}, {...}, {...}] Conclusion Frequently Asked Questions

Q1. What is Pprint used for?

A. Pprint (pretty print) is a Python module used for formatting complex data structures more readably and organized, especially when printing them to the console or writing to a file.

Q2. What is the difference between print and Pprint?

A. The main difference between print and Pprint is that Pprint is designed to format complex data structures such as dictionaries and lists, preserving their structure and providing indentation. In contrast, print is used for simple output of values or strings.

Q3. Is Pprint standard in Python?

A. Pprint is not a standard built-in module in Python, but it is included in the Python Standard Library, meaning it is available by default in most Python installations.

Q4. Is Pprint native to Python?

A. Yes, Pprint is native to Python as it is included in the Python Standard Library, allowing developers to utilize its functionality without needing external dependencies or installations.

Learn How To Speed Read With Syllable

Subvocalization is the act of “sounding out” words as you read them. Nearly everyone does it. It happens on a subconscious level. It is how we were taught to read and makes it possible to visualize the sound of words in order to interpret and comprehend them.

Syllable is an app that trains you to stop subvocalizing so you can read faster. It starts you off at a slow, comfortable pace, and works you up to 1,500 words per minute. You’ll be able to read an entire book during your lunch break with the help of this app…


With the most minimalist of designs, this app features two things: a white background and black text. There is a bright green border around your reading window, but there is very little else.

When you add an article to read in Syllable, it will be listed with the amount of time it will take to read based on how many words per minute (WPM) you’ve selected. For example, if you choose to read a particular article at 150 words per minute, it will show you that the article will take you four minutes and 36 seconds to read. If you speed up your WPM time to 250, it will shorten the time it takes to get through the same article to two minutes and 45 seconds.

You can add articles from your Instapaper or Pocket account by setting each app to allow access from Syllable. When you save an article in either app, it will automatically be populated into Syllable. You can also add articles by copying and pasting a URL link or write or paste your own text into a readable post.

In the settings section, you can change the font style, increase or decrease the size of the letters, switch from day to night mode, adjust the WPM speed, add more words to the screen from one to five, and change the brightness level of the screen.

App Use

To get started, log into your Pocket or Instapaper account. You don’t have to have these apps to use Syllable, but it makes it much easier to add articles. Once logged in, go back to your Pocket or Instapaper app and start grabbing articles to read. Then, open Syllable to see the generated list that will have all of your offline reading articles.

Pick a post by tapping it. When you do, you will be taken to a page that has a white background and the first word of the article. You can either start reading right away by tapping the word, or make the necessary changes to fine-tune your reading experience. I found that default starting WPM speed of 50 is much too slow and found that 225 WPM was a comfortable speed to begin my training.

You can also increase or decrease the size of the font. It is helpful to have large letters when trying to read fast, but not particularly realistic since the average font size of an article is 12.

After adjusting the speed and size of the words, try reading your first article. You will notice that you are not able to sound out the words in your head the way you normally do. This is because your brain is being forced to keep pace with the words that appear on the screen.

You can switch the screen to night mode in the settings section for a black background with white font. This works better when you are in a dimly lit environment because the bright white background can be harsh on the eyes.

While you are reading an article, you can tap the word to pause it, rewind a few seconds, and fast-forward a few seconds. When you’ve finished a whole article, you can tap it again to restart it.

When you are done reading an article, go back to the list to mark it as read. Swipe the post from left to right to bring up a check mark. Or, if you want to remove it from the list, swipe the post from right to left to bring up an “X” mark. This will delete the article from your list.

To add a new post without going through Instapaper or Pocket, copy the link to the article you want to read and then open Syllable. It will automatically ask you if you want to add the copied link to the list. Select “yes” to add it.

You can also write your own post to read in Syllable. Tap the plus (+) symbol at the top right of the screen to call up the options. Then, tap the “Text” tab and begin writing. You can either type your own words, or add an email that was sent to you, or some other text that you’ve copied. Just paste it into the Text post and tap the “Done” tab in the upper right corner of the screen and you can find it in the list and read it whenever you like. You’ll even be able to tell how long it will take to read at your current WPM pace.

The Good

If you are trying to learn how to speed-read, this is a great app for helping you retrain your brain to not sound out words. I love being able to add articles from my Pocket account. Plus, being able to copy and paste emails into the Text feature makes reading messages from others a more focused event. I am less distracted while reading and more engaged in what is in front of me.

The Bad

It would be nice to be able to add more reading apps to the list of compatible connections. I’d like to be able to add articles from the New York Times app or Flipboard to my reading list.

There were a few times when I was unable to restart an article that I had finished reading. I had to exit back to the article list and then select the post again in order to read it.


Syllable is on sale for $0.99, which is the perfect price for an app like this. Other speed-reading apps can be downloaded for free, but require an in-app purchase in order to access all of the features. Some of them cost $4.99 to unlock. I don’t know the full price of the app, but I can say it is definitely worth $0.99. However, anything higher makes it a niche app that would only be worth buying if you are really into the idea of learning to speed-read.


I’ve always wanted to learn how to read faster. I’m actually kind of slow at it. This app is great for slowly teaching you how to increase your WPM speed while helping you retrain your brain to stop subvocalizing when you read. It’s like Couch to 5K for your brain. If you are interested in learning how to speed read, download this app while it is on sale for $0.99.

Related Apps

ReadQuick is one app that also offers access to Instapaper and Pocket and lets you set the speed of words. Another similar app is Speed Reader, which has a more skeuomorphic look to it.
