You'd probably notice this `__proto__` property every time you log an `object` into the developer console.

![proto](https://thepracticaldev.s3.amazonaws.com/i/8qwwzv6jwrgi3mys4g2b.png)

In this post, I'm gonna try to explain where this `__proto__` comes from, what it contains, and anything in between. So, let's get this `__proto__`.

First, let's understand how a JavaScript `object` gets constructed. Once you understand how an `object` gets constructed, `__proto__` property is gonna make a lot more sense than otherwise.

## How an `object` get constructed?

A JavaScript `object`, always, get constructed/produced by a constructor function. Now, you'd probably say "But, object literals? They are not constructor functions."

Well, object literals are just syntactic sugar. You can write objects without using object literals. See the example below, both syntax would produce the same output. The second approach gives us more power(which we won't discuss here) which object literal takes away from us.

```js
// an object using object literal
const person = {
  name: "John",
  age: 30
};

// an object using Object constructor function
const person = new Object();
Object.defineProperties(person, {
  name: {
    value: "John"
  },
  age: {
    value: 30
  }
});
```

Now that we know that every `object`, in JavaScript, is constructed by a constructor function, let's get back to the original question.

## What is `__proto__`?

`__proto__` is a property, in every JavaScript `object`, which points to `object`'s constructor function's `prototype` property. I know it's a bit hard to grasp, but let me simplify it for you.

Every constructor function has this `prototype` property on them. The picture below shows us `Object` constructor function's `prototype` property.

![prototype](https://thepracticaldev.s3.amazonaws.com/i/kvmju7afrsqloq7fftoc.png)

So, every `object`, we'd construct/produce from `Object` constructor function, would have `__proto__` property pointing to `Object` constructor function's `prototype` property.

## Example

When we use object literals, as we did in the example below, `Object` constructor function is used to construct/produce the object. Now that we have a `person` object constructed/produced from `Object` constructor function, we can verify that `__proto__` from our `person` object is same as `prototype` from `Object` constructor function.

```js
// an object using object literal
const person = {
  name: "John",
  age: 30
};
// verify
console.log(person.__proto__ === Object.prototype); // true
```

If you didn't understand something from the post, or I missed something, please, let me know.

The post [Get Length of the List using Python len() function](https://www.positronx.io/get-length-of-the-list-using-python-len-function/) appeared first on [positronX.io](https://www.positronx.io).

Hello folks, today we are going to learn how to **get the length of a list using Python len()** function. Python is the most popular programming language these days, and it offers a built-in function to calculate the size of the data in a list, array, tuple etc.

We are going to explore the Python `len()` function, this function takes a data object as a parameter and returns the number of items in a data list. Here, the important thing is to remember is if you pass a string as a parameter, then the **len()** method will return the number of the characters of the string.

{% youtube J-MKrg8JBtc %}

In order to build HA & Resilient applications in AWS, you need to assume that everything will fail. Therefore, you always design and deploy your application in multiple AZ & regions. So you end up with many unused AWS resources (Snapshots, ELB, EC2, Elastic IP, etc) that could cost you a fortune.

One pillar of AWS Well-Architected Framework is Cost optimization. That’s why you need to have a global overview of your AWS Infrastructure. Fortunately, AWS offers many fully-managed services like CloudWatch, CloudTrail, Trusted Advisor & AWS Config to help you achieve that. But, they require a deep understanding of AWS Platform and they are not straighforward.

![Support GCP](https://labouardy.com/images/dashboard-gcp.png)

That’s why I came up with Komiser a tool that simplifies the process by querying the AWS API to fetch information about almost all critical services of AWS like EC2, RDS, ELB, S3, Lambda … in real-time in a single Dashboard.

![Support Multiple AWS Accounts](https://s3.eu-west-3.amazonaws.com/komiser-assets/images/dashboard-aws-multiple.png)

Komiser is 100% Open Source, it support both AWS and GCP in one place. Azure support will released soon.

{% github mlabouardy/komiser %}

Hope it helps ! The CLI is still in its early stages, so you are welcome to contribute to the project on GitHub.

---
In mobile development often there is a need to run a method couple of times, or on a fixed schedule , like playing an animation or fetching data every some seconds, according to the Android's best practices, it is recommended to use the Handler object, the following snippet can come in handy when you have a lot of reoccurring tasks 

```c#
import android.os.Bundle;

public interface IReoccurringTask {
    void run(Bundle bundle);
}
```

```c#
import android.os.Bundle;
import android.os.Handler;

public class ReoccurringTaskScheduler {

    private Handler handler = new Handler();
    private Runnable runnable;
    private IReoccurringTask reoccurringTask;

    private ReoccurringTaskScheduler(){}

    public ReoccurringTaskScheduler(IReoccurringTask reoccurringTask) {
        this.reoccurringTask=reoccurringTask;
    }

    public void Schedule(long initDelay, final long interval) {

        runnable = new Runnable() {

            @Override
            public void run() {
                try {
                    reoccurringTask.run(null);
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    handler.postDelayed(this, interval);
                }
            }
        };
        handler.postDelayed(runnable, initDelay);
    }

    public void Schedule(final Bundle bundle, long initDelay, final long interval) {

        runnable = new Runnable() {

            @Override
            public void run() {
                try {
                    reoccurringTask.run(bundle);
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    handler.postDelayed(this, interval);
                }
            }
        };
        handler.postDelayed(runnable, initDelay);
    }

    public void cancel() {
        if (runnable != null)
            handler.removeCallbacks(runnable);
    }
}
```

and you can define your custom logic like this 

```c#
private class ReoccurringLogicClass implements IReoccurringTask{

    @Override
    public void run(Bundle bundle) {

        //reoccurring logic
    }


}
```

and then use it like this

```c#
ReoccurringTaskScheduler rTask=
    new ReoccurringTaskScheduler(new ReoccurringLogicClass()).Schedule(1000,2000);
```

and cancel it like this 

```c#
rTask.cancel();
```

Happy coding :)

While coding sometimes little tiny things are so frustrating , like forgetting to instantiate a List object before adding a new item, an easy solution will be to write an extension method like this   
        
```c#
public static class ListExtension
{
    public static void Add<T>(this List<T> list, T value, out List<T> newInstance)
    {
        if (list == null) list = new List<T>();
        list?.Add(value);
        newInstance = list;
    }
}
```

and then use it like this 

```c#
[Test]
public void SafeAddTest()
{
    List<string> list = null;
    list.Add("test",out list);
    
    Assert.AreEqual(1,list.Count);
}
```
therefore whenever you want to make sure that the list that you are going to add to it is already instantiated you can simply pass the list instance as the second variable and that's it.

Happy coding :)

I was at ReactEurope and now I "get" React Hooks

---

Last week, I went to Paris to spend some time there with my family and to attend ReactEurope.

Based on the kind of mediocre design of their website I did not expect a lot of care to go into the organization of the conference. I expected a dull conference room in a hotel and some interesting talks.

I got some interesting talks and a dull, stuffy conference room in a dull, ugly area of Paris. The room was too small for so many people though. The air was terrible and people coughing and sneezing all around me. I was not capable of spending a lot of time in there.

Instead, I took some time to read through the [React Hooks documentation](https://reactjs.org/docs/hooks-intro.html). Let me just take a second to say how well written and how thought-out the documentation is. Really world-class. Unlike the ReactEurope conference.

I also started rewriting [my Grit editor](https://github.com/kahlil/grit) from [Preact](https://github.com/preactjs/preact) and [htm](https://github.com/developit/htm) to React with hooks. Just so to get familiar with them.

It is always hard to convey how features like that impact your development experience without trying it out. I have only rewritten a small part of it so far but I like it a lot.

The concept of custom hooks especially seems to have a lot of impact when it comes to simplifying your code.

Here is an example.

In order for Grit to work the user has to store the path to their Markdown files in the settings. I store the settings by using this ace package called electron-store by Sindre Sorhus (Shout out to him, what would I do without his stellar open source work?!).

This path needs to be shown in the UI via a state variable and it has to be synced back to the electron-store if it is changed.

So I created this custom hook called useElectronStore to read the path from electron-store and to set the filePath state variable from it and to set both, the state variable and electron-store, with the new value once it is changed.

And it makes getting and setting electron-store values incredibly easy. The API basically looks like this:

```
const [someValue, setSomeValue] = useElectronStore('someValue', '');

```

The `'someValue'`-string is the path in electron-store and the second value is the default value for it.

I can now say that I “get” React Hooks because ReactEurope was not that great. Works for me.

Does Anyone Know of Any *Discrete* Clustering Algorithms?
Tags: help, clustering, algorithms
Published: 2019-06-07 08:34:48

I'm doing some research into clustering algorithms and every source I seem to find discusses 2D (or higher-dimensional) clustering of continuous data. The nearest thing I've found to what I'm looking for is [this article](http://paulovinicius.com/uploads/3/5/3/1/35316805/2015_iros_rob.pdf) which discusses _discrete-continuous_ clustering (where the `x` and `y` axes are quantized into cells, but the `z` axis is allowed to vary continuously).

Has anyone come across any algorithms which perform cluster analysis of purely discrete data? Specifically 2D?
