Published: 2023-01-20 12:14:47

## Initial check

 The importance of thoroughly inspecting a used MacBook before purchasing
 Buying used can be a great way to save money, but it's important to make sure you're getting a device in good condition
_Check find and system preferences, security privacy, unlock lock_
_Remove Last User Apple ID_

## Year of manufacture

 Discover the year of manufacture immediately upon seeing a used MacBook advertisement
 This information is important because it indicates the possible usage time of the machine and also points to the remaining deadline for the product to be considered obsolete

## Serial number

 Check the MacBook's serial number to ensure its authenticity
 It's important to verify this aspect to guarantee the product's originality

## Hardware test

 The Apple Hardware Test (AHT) contains a set of diagnostics that will test the Mac's hardware
 This is the best way to rule out possible problems with the used MacBook's hardware

## Keyboard and trackpad

 Check each key individually and inspect the trackpad's condition
 A simple stuck Shift key can cause a lot of trouble on a daily basis
 The quality of the trackpad is one of the MacBook's signatures, so if it's not working properly, be suspicious

## Battery condition

 Checking the battery condition is very important
 Replacing a Mac's battery can be quite expensive, depending on the MacBook model
_if possible check if the charger is the original_

## Camera (iSight)

 Few people remember to test the Mac's camera
 The best way to check if the MacBook's camera is working is to open the Photo Booth app or the FaceTime application

## Sound and audio

 Make sure the device's internal speakers are working properly
 Check the input by connecting a pair of headphones to test the port, just to be sure
_Make sure your internet connection is working_

## Screen

 Look for dead pixels on the screen by opening a completely white image in full screen
 It's normal for a pixel or two to not light up after a while, but it's important to check this condition

## Conclusion

 In summary, before buying a used MacBook, it's important to thoroughly inspect the device to ensure you're getting a product in good condition
 By checking these aspects, you can be sure you're making a good purchase and saving money. Remember that buying a used MacBook can be an excellent option, as long as you're aware of the possible risks and are prepared to check all of the above aspects. By following these tips, you can be sure you're making a safe purchase and be ready to enjoy all the advantages of a MacBook in great condition.

My Goals to 2023! Are you ready?
Tags: devops, cloud, productivity
Published: 2023-01-20 12:03:00

This is my first time writing in a dev blog. I am super excited that I have time for this.

In our lives, we always have tasks; every day we go to work and back home and don't have time to stop and write something from our hearts or our brains. So I decided to write some of my goals for the new year. 

One of my first goals is to take always tasks that have a small effort and do them right now and not postpone them for later. I think this is very important and should be good.

Another goal is not personal; this one is from the professional side. We always have new challenges at work and new tasks, so we can do them in a couple of ways. But I think making decisions is super important for boosting your career as a professional. As well as learning new tech stacks and completing expertise in the ones I already know.

Another goal which I must keep from last year is to always learn and never stop. Active learning is one of the best ways to expose myself to new tech stacks, research and implement it in my work.

And one of the last of my goals is to start and complete some side projects, take on some DevOps projects that can solve problems for R&D teams and make their work better. This project can be in IaC, CI/CD, Cloud, etc.

In conclusion, I think we need to sometimes stop and think about our next goals and which goals we want to achieve from last year.
I hope my first article in the blog will not be the last one :)
Securing Your Network: Understanding the Differences between Security Groups and Network Access Control Lists
Published: 2023-01-20 12:01:25


Security groups and network access control lists (ACLs) are both important tools for securing your network on the AWS cloud, but they serve different purposes and have different use cases.

Security groups are like a bouncer at a club. They control inbound and outbound traffic to and from your resources, like a bouncer controls who can enter and exit a club. Just like a bouncer checks IDs and only allows certain people to enter the club, security groups check the IP addresses and ports of incoming and outgoing traffic, and only allow traffic that meets certain rules. This way, security groups can help protect your resources from unauthorized access and malicious attacks.

Network ACLs, on the other hand, are like a security guard for a building. They control inbound and outbound traffic at the subnet level, like a security guard controls who can enter and exit a building. Just like a security guard checks IDs and only allows certain people to enter the building, network ACLs check the IP addresses and ports of incoming and outgoing traffic, and only allow traffic that meets certain rules. This way, network ACLs can help protect your entire subnet from unauthorized access and malicious attacks.

One key difference between security groups and network ACLs is that security groups are associated with individual resources (such as an EC2 instance), while network ACLs are associated with subnets. This means that security groups provide a more granular level of control over traffic, while network ACLs provide a more broad level of control. Additionally, security groups only allow or deny traffic, while network ACLs allow or deny traffic and also prioritize traffic with a number range from 100-32766.

In short, security groups and network ACLs are both important tools for securing your network on the AWS cloud, but they serve different purposes and have different use cases. Security groups are like a bouncer at a club, controlling inbound and outbound traffic to and from your resources at the individual resource level. Network ACLs, on the other hand, are like a security guard for a building, controlling inbound and outbound traffic at the subnet level.

AWS OpenSearch: The Ultimate Data Discovery Tool
Published: 2023-01-20 11:52:39

By <u>Namwakira Pauline</u>


AWS OpenSearch is a service that allows you to easily add search capabilities to your applications and websites. It is built on top of Elasticsearch, a powerful and popular open-source search engine.

An analogy for AWS OpenSearch would be a search engine like Google. Just like Google allows you to search for information on the internet, AWS OpenSearch allows you to search for information within your own applications and websites. It allows you to index your data, create search domains, and define search fields, so that users can easily search for the information they need.

The working of AWS OpenSearch is based on three main components:

1. Indexing: This is the process of adding your data to the search engine, so it can be searched later. This is similar to indexing a book, where you create an index of terms and their page numbers, so you can quickly find the information you need.

2. Search domains: A search domain is a collection of search fields that are used to search a specific set of data. It is like creating different sections in a library, where each section has books on a specific topic.

3. Search fields: Search fields are the specific data fields that you want to search, like the title, author, and ISBN number of a book.

AWS OpenSearch offers several **solutions** such as:

1. Cost optimization: You can use reserved instances and spot instances to lower the cost of running the service.

2. Monitoring and troubleshooting: You can use CloudWatch and Elasticsearch service domains to monitor and troubleshoot the service.

3. Customization: You can use Elasticsearch plugins and custom scripts to customize the search engine to suit your needs.


AWS OpenSearch offers several **advantages** such as:

1. Easy to use: The service is easy to set up and use, and it allows you to add search capabilities to your application with minimal coding.

2. Scalable: It can handle large amounts of data and traffic, so it can grow with your business.

3. Customizable: You can customize the search engine to suit your needs, including defining search fields and search domains.

However, it also has some **disadvantages** such as:

1. Cost: The service can be expensive, especially if you have a large amount of data or a high volume of traffic.

2. Maintenance: The service requires regular maintenance and monitoring to ensure that it is running smoothly.

3. Limited control: As it is a managed service, you have limited control over the underlying infrastructure.

In summary, AWS OpenSearch is a service that allows you to easily add search capabilities to your applications and websites, it is based on Elasticsearch, it's similar to Google, it uses indexing, search domains, and search fields. It offers advantages like easy to use, scalable, and customizable, but also has some disadvantages like cost, maintenance, and limited control. AWS OpenSearch also offers solutions to optimize cost, monitor and troubleshoot, and customize the search engine.
Text To Speech Converter with JavaScript
Tags: webdev, javascript, beginners, html
Published: 2023-01-20 11:36:54

Converting text to speech using HTML, CSS, and JavaScript can be done using the SpeechSynthesis API. 

The **SpeechSynthesis API** is a built-in JavaScript API that allows you to convert text to speech directly in the browser without the need for any external libraries.

Here is an example of how to use the SpeechSynthesis API to [convert text to speech](https://foolishdeveloper.com/text-to-speech-converter-javascript/) in HTML, CSS, and JavaScript:

**HTML Code**
```html
<div id="text-to-speech">
  <textarea id="text"></textarea>
  <button id="speak-button">Speak</button>
</div>

```
**CSS Code**
```css
#text-to-speech {
  display: flex;
  flex-direction: column;
  align-items: center;
}

#text {
  width: 300px;
  height: 100px;
  padding: 10px;
  margin-bottom: 10px;
}

#speak-button {
  padding: 10px;
  font-size: 18px;
  background-color: #4CAF50;
  color: white;
  border: none;
  cursor: pointer;
}

```
**JavaScript Code**
```js
// Get the text area and speak button elements
let textArea = document.getElementById("text");
let speakButton = document.getElementById("speak-button");

// Add an event listener to the speak button
speakButton.addEventListener("click", function() {
  // Get the text from the text area
  let text = textArea.value;

  // Create a new SpeechSynthesisUtterance object
  let utterance = new SpeechSynthesisUtterance();

  // Set the text and voice of the utterance
  utterance.text = text;
  utterance.voice = window.speechSynthesis.getVoices()[0];

  // Speak the utterance
  window.speechSynthesis.speak(utterance);
});

```
This example creates a text area and a button in the HTML, styles them using CSS, and then uses JavaScript to add an event listener to the button that converts the text in the text area to speech when the button is clicked.

This is just a basic example and you can customize it further according to your needs by, for example, adding more options to the speech synthesis and also you can use libraries such as responsivevoice.js, meSpeak.js or annyang.js to add more functionalities and features.
Top 3 Factors of Website Development and Designing
Published: 2023-01-20 11:31:19

In today’s technological world, no business can groom without a website. An online identity of a business is as important as it’s offline identity. The importance of having an attractive online identity needs no descriptions because everyone, who is up to date with the technology, knows that digital marketing plays a crucial role in increasing revenue. 

The only way to create an online identity for your business is to create a website for your company. A website, developed and designed by the best web design and **[web development company](https://www.qmoniqs.com/web-development)**, can make your business reach a broader audience in comparatively less time.

You can save that extra money in the marketing of your website, and hence ensure better conversion for your business.

**2. It’s in trend**
There was a time when only a small fraction of the companies used to have a website for their businesses. But nowadays, almost every business has its own website and the reason is the increasing involvement of people towards the online websites. People, in the form of visitors, tend to surf the internet for “n” number of reasons. From getting informed by getting up to date with the technology, from shopping online to paying bills at one tap, reasons to surf the internet are many and so as the websites. So, designing a website is no more one-of-a-kind thing. Hence, if you have something to sell or offer, get a website designed and developed and flow with the trend.

**3. It keeps your customers connected to you**
If you want to keep your customers with you for a long time, get connected to a leading **[web design services company in India](https://www.qmoniqs.com/web-development)**, and let it reveal all about your business.

E-commerce has become the most suitable shopping means in recent times. Developing your online marketplace needs a lot of experience, expertise, and a comprehensive understanding of different platforms like WordPress, Magento, WooCommerce, Big Commerce, Wix, and many options.
Balancing Speed and Thoroughness: Best Practices for Reviewing and Approving Pull Requests
Tags: javascript, typescript, prs, codereview
Published: 2023-01-20 11:27:49

As a software developer, one of the most important aspects of your job is to review and approve pull requests (PRs) submitted by your team members. 

This process is critical for ensuring that the codebase remains clean, maintainable, and free of bugs. 

However, it can also be a source of frustration, especially when you are pressed for time and asked to quickly approve a PR without fully reviewing it.

One of the biggest challenges when reviewing PRs is balancing the need for speed with the need for thoroughness. 

On one hand, you want to be able to quickly approve PRs so that your team members can move forward with their work. 

On the other hand, you don't want to approve something that is going to cause problems down the road.

One way to strike a balance between speed and thoroughness is to establish a clear set of guidelines and expectations for PRs. 

For example, you might require that PRs include a detailed description of the changes made, as well as any relevant test cases or documentation. 

This will make it easier for you to quickly review the PR and identify any potential issues.

Another key aspect of reviewing PRs is to be proactive in identifying and addressing potential issues. 

For example, you might use automated tools to check for common coding errors or to check for compliance with your team's coding standards. 

By catching these issues early on, you can help to prevent them from becoming bigger problems down the road.

Additionally, it's very important to be transparent and communicate well with your team members. If you find a problem with a PR, don't be afraid to bring it up and discuss it with the person who submitted it. 

The sooner you can identify and address an issue, the less likely it is to cause problems later on.

Reviewing and approving PRs is an important part of the software development process. 

It can be challenging to balance the need for speed with the need for thoroughness, but by establishing clear guidelines, being proactive in identifying and addressing potential issues, and communicating well with your team members, you can help to ensure that the codebase remains clean, maintainable, and free of bugs.

**Remember**, it is better to take some time to review and approve a PR correctly rather than approving a poor quality one that can cause problems in the future.
It's okay to commit lint fixes
Tags: productivity, programming, git, discuss
Published: 2023-01-20 11:12:28

Trigger-warning, this is all highly opinionated. If you feel different about it, let's discuss :smile:

It bases on my assumption, that a "clean" git history is something **I might want to achieve** but **I don't necessarily need to achieve** and the tradeoff between what I get by a clean history and the work I have to do for it seems to be negative for teams below enterprise-level size. Therefore commits about "lint fixes" are totally okay imo.

Here are some rather technical arguments:

- good commit messages are much more of importance; you can [use a convention for commit messages](https://www.conventionalcommits.org) that describes lint fixes; example: 
```"fix(ui): eslint compliance"```
- if you use a convention then you can easily filter these commits: 
```git log --invert-grep --grep="eslint compliance"```
- you can still use git [squash-merge](https://git-scm.com/docs/git-merge#Documentation/git-merge.txt---squash) if a clean history is of most importance

Here are some rather human arguments:

- for newcomers and beginners it's often much easier to first commit the work they have done (feel safe; make sure things a working) and then apply formatting, refactoring etc.
- convention over configuration does imo also apply to the dev environment, which is why I regularly omit pre-commit hooks
- I also like to avoid to put my juniors into a skinner-box that only lets them pass, once they behave as I intend them to; rather I'd like them to learn conventions

What do you think? Something is missing? Is this unprofessional and I should never step a foot into your company's door? Let's discuss :smile:
Scala class inherit or extend another case class not possible
Tags: scala, bigdata, datascience
Published: 2023-01-20 10:52:16

#Scala case class inherit , #extend , #case class , #case class #inheritance #code #coding_question

## 
It is not possible that we can not inherite another case class .

**If you want to inherite then you can create Trait**
Here we create Student Trait
case class Student(identifier: String) {}

case class SportTeam (salary: Long) extends student
Here we define a Student
trait Student{ def identifier: String }

Here we create class which is extends Student
case class SportTeam(identifier: String, salary: Long) extends Student

## Case classs not able to extend of another case class because of following -

1. It led to wrong circumstances and unexpected behaviour.
2. It produce issue in multiple problems in the pattern matcher.
3. Case class most consistent with inheritance would violate the spec.
4. Scala doesn’t generate a copy method if one already exists in the class/traits the case class inherits.

1. Pay them.
2. Warn them if you find they are working. The culture should expect everyone to recover before working.
3. Encourage everyone to have an illness plan – where can anyone find what work needs to be covered, and who’s best placed to cover it.
