The useDeferredValue hook - React 17.0 beta features
Tags: javascript, react, typescript, webdev
Published: 2023-01-08 15:35:51

## Introduction to the useDeferredValue Hook

React's useDeferredValue hook is a new feature that was introduced in React 17.0 as a beta release. It allows a developer to specify a value that should be used with a delay, allowing for the possibility of rendering an intermediate state while waiting for the deferred value to resolve. This can be useful in situations where you want to optimize the perceived performance of a component by rendering content as quickly as possible, even if it is not the most up-to-date.

## When to Use useDeferredValue

One common use case for useDeferredValue is when you have a slow-loading prop that is passed to a component, but you don't want to block rendering of the rest of the component while waiting for the prop to resolve. Instead, you can use a placeholder value or an intermediate state while waiting for the prop to resolve.

Another use case is when you have a value that is updated frequently, but the updates are not critical to the user experience. In this case, you can use useDeferredValue to only update the value after a certain delay, allowing for a smoother experience for the user.

## How to Use useDeferredValue
Using useDeferredValue is similar to using other React hooks. First, you need to import the hook from the react package:

```javascript
import { useDeferredValue } from 'react';
```

Next, you can call the hook within a functional component and pass it two arguments: the value you want to defer, and the delay time in milliseconds. The hook will return the deferred value, which you can then use in the component like any other value:

```javascript
const MyComponent = ({ slowLoadingProp }) => {
  const deferredProp = useDeferredValue(slowLoadingProp, 500);

  return (
    <div>
      {deferredProp}
    </div>
  );
};
```

In the example above, the component will render with the placeholder value of slowLoadingProp for at least 500 milliseconds before updating with the actual value.

It's important to note that useDeferredValue only delays the rendering of the value, not the resolution of the value itself. This means that if the value takes longer than the specified delay to resolve, it will still be displayed as soon as it is available.

## Conclusion

The useDeferredValue hook is a useful tool for optimizing the perceived performance of a React component by allowing for the rendering of intermediate states or placeholder values while waiting for slow-loading or frequently updated values to resolve. It is easy to use and can greatly improve the user experience of your application.

How to troubleshoot docker unauthorized 401 error
Tags: devops, docker, mvn, java
Published: 2023-01-08 15:19:04

This is an example from a public repository that was causing an issue. 

`https://github.com/MilenkoMarkovic/intens-api-2022`
    

I created a hub.docker.com account which comes with one free repository. 

Then proceed with the steps below:

Here is my test Dockerfile:

```
FROM openjdk:8-jdk-alpine

WORKDIR /opt/app

COPY target/aamdevsecops-1.1.1-SNAPSHOT.jar /opt/app/

CMD ["java","-jar","aamdevsecops-1.1.1-SNAPSHOT.jar"]
```

Of course, i changed the `<name>,` `<version>` and `<artifactoryId>` in `pom.xml` file to match my Dockerfile.

First, i built the package locally by issuing this command on the intense-api git project folder:

`mvn package`

Then, I built the docker image out of it:

`docker build -t aamdevsecops:1.1.1 .`

then logged in to docker with my hub.docker.com credentials.

docker login # you will be prompted for credentials of hub.docker.com account

tagged the image: docker tag <Image ID> aamdevsecops/devops-bootcamp:latest

then: `docker push aamdevsecops/devops-bootcamp:1.1.1`

Finally, I did:

`docker run --name aamdevsecops -p 8090:8090 aamdevsecops/devops-bootcamp:latest`

And here's the result:

Wireless Hacking 101: How to Crack WiFi Passwords
Published: 2023-01-08 14:55:57

Wireless hacking is a process of gaining unauthorized access to a wireless network. It can be used to gain access to an Internet connection, to sniff out sensitive information, or even to gain access to a computer system. Wireless hacking can be done with a variety of tools and techniques, and it is becoming increasingly popular due to advances in technology and the availability of wireless networks.


**Demonstrate how to use a brute-force attack to crack a WiFi password.**

A brute force attack is an attempt to crack a WiFi password by systematically trying every possible combination of characters until the correct password is found. Here are the steps to perform a brute force attack on a WiFi network: 

1. Download and install Kali linux operating system  which can you find inbuilt wifi hacking tools  

2. Scan for available WiFi networks in your area and select the one you want to hack. 

3. Enter the target network's name and click “start” to begin the attack. 

4. Type in the possible password combinations that you think might be the right one. 

5. The software will try each combination until it finds the correct one. 

6. Once the correct password is found, the software will display the message “successful”. 

7. You can now access the WiFi network using the cracked password.

 ![Merging Django contexts: merge dicts in Python](https://images.unsplash.com/photo-1453748866136-b1dd97284f49?crop=entropy&cs=tinysrgb&fit=max&fm=jpg&ixid=MnwxMTc3M3wwfDF8c2VhcmNofDEyfHxkaWN0aW9uYXJpZXN8ZW58MHx8fHwxNjczMTg3MjI2&ixlib=rb-4.0.3&q=80&w=2000)

While developing web apps for Django you will eventually need to join more than one dictionary together. This is because Django uses dictionaries to define the context for template rendering. But what is the case you would need to join a dictionary instead of just creating one in place?

The most common use case I encounter is when you have a dynamic common set of elements, such as a navigation bar or a footer, that appear on every page you render. In this case, for each page to be rendered, the context of the common elements and the context for the specific page will be needed. You will therefore need to combine multiple dictionaries.

Python offers multiple ways to combine multiple dictionaries. Let's quickly guide you through some of them.

## Using \*\* operator

I consider this to be the easiest method yet it's considered to be a hack. The double-star operator is a way to pass multiple arguments into a function directly using a dictionary.

```
common_context = {'site_name': 'Hello world site'}
page_context = {**common_context, 'page_specific_element': 'Welcome!'}
```

## Using | operator

This was [added](https://docs.python.org/3.9/whatsnew/3.9.html#dictionary-merge-update-operators) to Python 3.9. Using the "|" operator 2 dictionaries can be merged together conveniently.

```
common_context = {'site_name': 'Hello world site'}
page_context = common_context | {'page_specific_element': 'Welcome!'}
```

## Using update() method

After the execution of the following snippet the `page_context` variable holds a dictionary with the merged key-value pairs. Note that the result of the `update()` call is `None` so you can't use the method call directly in a return call.

```
common_context = {'site_name': 'Hello world site'}
page_context = {'page_specific_element': 'Welcome!'}
page_context.update(common_context)
```

There are a few more ways to merge dictionaries, such as the manual way of iterating through one dictionary and adding key-value pairs to the other, but I think the mentioned methods are more than enough to choose from. Hopefully, you can now have one less thing to worry about when rendering your templates in Django.

Happy coding!
TIL: Non standard postgres types in livebook
Tags: elixir, livebook, postgres
Published: 2023-01-08 13:01:43

Livebook has a new, nice feature that allows you to connect to a database. It works with basic data types.

![livebook screenshot](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/jdeansqhyq5ey9647oo3.png)

But I found a problem when the data type is not supported by postgrex.
![livebook screenshot](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/vvu21nwb2ba0pdfept1c.png)
In this case, you can either have to write a custom postgrex extension like the example [here](https://github.com/elixir-ecto/postgrex/issues/439). In postgrex GitHub repo, there are many [examples](https://github.com/elixir-ecto/postgrex/tree/master/lib/postgrex/extensions) for common data types, but XML is missing there.

You can also cast your field to a supported data type:
```sql
SELECT demographics::text from person.person   
```
![livebook screenshot](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/51c7kecpqws2dmqlayut.png)
To play with this example, you can install the example [Adventureworks](https://learn.microsoft.com/en-us/sql/samples/adventureworks-install-configure) database provided by Microsoft. I made an [elixir converter](https://github.com/dkuku/AdventureWorks-for-Postgres) that converts some of the files to a format accepted by PostgreSQL, and also updated the previous version to properly name the columns with underscores.

WhatsApp to introduce report status update feature.
Tags: whatsapp, feature, news
Published: 2023-01-08 13:22:22

WhatsApp states that the ‘report status update’ feature is important for maintaining the safety of both the platform and its users.

WhatsApp have been rolling out new features every now and then, and enhancing its user interface. In a similar bid, WhatsApp teased the report status update feature in a recent blogpost on Wabetainfo.

WhatsApp shared a screenshot showing a “report” button within the status options. In case you report a status update, its content will be forwarded to the moderation team for review to determine if it violates WhatsApp Terms of Service.

The ‘report status updates’ feature is still under development on WhatsApp beta for Android and planned to be released with a future update.

WhatsApp`s new feature to allow transfer data on Android; Know details here
Tags: whatsapp, android, webdev, programming
Published: 2023-01-08 13:12:09

Meta-owned WhatsApp is reportedly working on a new feature called -- 'Chat Transfer', which will allow users to transfer their data from one Android device to another using a local network. According to WABetaInfo, the company will bring the new feature to a future update of the app as it is in the developing stage.

With this feature, users will be able to transfer chat history to a new device by scanning the QR code. It will eliminate the need for Google Drive, so users will no longer have to back up their chat data to the cloud service if they want to transfer the chats from one device to another, said the report.

Meanwhile, WhatsApp also launched proxy support for users all over the world, like millions of people in Iran and elsewhere who continue to be denied the right to communicate freely and privately. Choosing a proxy will enable them to connect to WhatsApp through servers set up by volunteers and organisations around the world dedicated to helping people communicate freely.

"We are making it easier for anyone to connect to WhatsApp using a proxy. So when a connection to WhatsApp is blocked, people have the power to restore access," said Will Cathcart, Head of WhatsApp.

Is it worth Switching to Mint OS from windows?
Published: 2023-01-08 12:51:59

Mint is a popular Linux-based operating system that is based on the Ubuntu distribution. It is known for its ease of use, stability, and wide range of software available in its repository. If you are considering switching to Mint from Windows, there are a few things you should consider:

- Compatibility with your hardware: Most hardware is compatible with Linux, but it is always a good idea to check if all of your hardware is supported before making the switch.
- Available software: While Mint has a wide range of software available in its repository, there may be some specific programs that you use that are not available on Linux. If you rely on a specific piece of software that is not available on Linux, it may not be practical to switch.
- Learning curve: Mint is a very user-friendly operating system, but it is still different from Windows. If you are new to Linux, you may need to spend some time learning how to use it.

Overall, switching to Mint can be a good decision if you are looking for a stable, user-friendly operating system and are willing to spend some time learning how to use it. However, if you rely on specific software that is not available on Linux or are not comfortable with the idea of learning a new operating system, it may not be the best choice for you.
"How to Get a 'GET' Response as an Array in Python
Tags: webdev, programming, tutorial, python
Published: 2023-01-08 12:50:24

If you are working with APIs in Python, you may want to retrieve the data from a GET request and store it as an array. In this tutorial, we will go over how to do this using the requests library and the json() method.
First, let's make a GET request to retrieve the data. We will use the requests library to send the request and store the response in a variable.

```
import requests

url = 'https://api.example.com/endpoint'
response = requests.get(url)

```
Next, we can use the json() method to convert the response to a dictionary.

```
data = response.json()

```
Now, let's say that the data we want is stored in the 'results' key of the dictionary. We can access it like this:

```
results = data['results']

```
The 'results' key contains a list of dictionaries, so we can iterate over the list and store each dictionary in an array.

```
array = []
for result in results:
  array.append(result)
```
That's it! Now you have the 'GET' response stored as an array in Python. You can access the data in the array by using the index, just like with any other list.

```
print(array[0])  # prints the first item in the array
print(array[1])  # prints the second item in the array

```
I hope this tutorial has helped you learn how to get a 'GET' response as an array in Python. If you have any questions, please leave a comment below."
