Operators in JavaScript: The Fundamentals
Tags: javascript, operators
Published: 2023-02-04 10:03:25

**Operators**
Operators in JavaScript are symbols that perform specific operations on operands, or values, to produce a new value. In this post, we will discuss the different types of operators available in JavaScript and how they can be used in our code.

**Arithmetic Operators**
Arithmetic operators perform basic arithmetic operations such as addition, subtraction, multiplication, and division. These operators are +, -, *, /, %, ++, and --.

For example, 2 + 3 would evaluate to 5 and 10 / 2 would evaluate to 5. The % operator returns the remainder of the division of two operands. For instance, 10 % 3 would evaluate to 1. The ++ and -- operators are used to increment and decrement the value of a variable by 1 respectively.

**Assignment Operators**
Assignment operators are used to assign a value to a variable. The most commonly used assignment operator is =. Other assignment operators include +=, -=, *=, and /=. These operators perform the respective arithmetic operation and assign the result back to the variable.

For instance, x = x + 3 can be written as x += 3.

**Comparison Operators**
Comparison operators are used to compare values and return a Boolean value of true or false. These operators include ==, !=, ===, !==, >, <, >=, and <=.

For example, 5 == 5 would evaluate to true, while 5 == 6 would evaluate to false. The === and !== operators perform strict equality checks, meaning they check both the value and type of the operands.

**Logical Operators**
Logical operators are used to perform logical operations such as and, or, and not. The && operator returns true if both operands are true, while the || operator returns true if either operand is true. The ! operator is used to negate a value and return the opposite Boolean value.

For instance, true && false would evaluate to false, while true || false would evaluate to true.

**Ternary Operators**
The ternary operator is a shorthand for an if statement. It is written as condition ? expression1 : expression2. If the condition is true, the operator returns expression1, otherwise it returns expression2.

For example, let x = 5 > 3 ? "yes" : "no" would assign the value "yes" to x.

**Conclusion**
In conclusion, operators play a crucial role in JavaScript and allow us to perform various operations on values. Understanding these operators and their use cases can greatly improve our ability to write efficient and readable code.

ChatGPT! How and Where?
Tags: transformers, chatgpt, textmodel, uses
Published: 2023-02-04 09:53:59

**ChatGPT** is a powerful _language model_ developed by **OpenAI** that uses advanced machine learning techniques to generate human-like text. This model was trained on a massive amount of data and fine-tuned to generate high-quality responses to a wide range of questions and prompts.

**How ChatGPT Works:**

1. Preprocessing: The input text is passed through a preprocessing step to convert it into a format that can be easily processed by the model. This step involves tokenizing the text into individual words or phrases and encoding them using a numerical representation.

2. Encoder-Decoder Architecture: ChatGPT uses a transformer-based encoder-decoder architecture to generate its outputs. The encoder takes the input text and converts it into a high-dimensional vector representation, while the decoder uses this representation to generate the output text.

3. Attention Mechanisms: ChatGPT uses attention mechanisms to focus on different parts of the input text when generating its output. This allows the model to generate more contextually relevant responses by taking into account the context of the input text.

4. Generative Process: The decoder then generates the output text one word at a time, using a process called autoregression. The model uses the previously generated words and the input representation to generate the next word in the sequence.

**Uses of ChatGPT:**

1. Chatbots: ChatGPT can be used to build advanced chatbots that can respond to customer inquiries in a natural and human-like manner.

2. Content Creation: ChatGPT can be used to generate articles, summaries, and other types of text content, making it a useful tool for content creators and marketers.

3. Text Generation: ChatGPT can be used to generate creative writing, poetry, and even jokes, making it a versatile tool for writers and entertainers.

4. Question Answering: ChatGPT can be used to build question-answering systems that can provide accurate answers to complex questions in a variety of domains.

In conclusion, ChatGPT is a powerful language model that has a wide range of applications in the fields of natural language processing and artificial intelligence. With its ability to generate high-quality text responses and its versatility, ChatGPT has the potential to revolutionize the way we interact with computers and automate many tasks that previously required human input.

K8s Dashboard on OKE
Tags: oraclecloudinfrastructure, oci, k8s
Published: 2023-02-04 09:49:29

Bismillah...

We will learn on how to deploy and access Kubernetes (K8s) Dashboard in Oracle Kubernetes Engine (OKE). 

First, we will create filename oke-k8s-dashboard-auth.yaml with below details:

```
apiVersion: v1
kind: ServiceAccount
metadata:
  name: oke-admin
  namespace: kube-system
---
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: oke-admin
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: cluster-admin
subjects:
- kind: ServiceAccount
  name: oke-admin
  namespace: kube-system
---
apiVersion: v1
kind: Secret
metadata:
  name: oke-admin-sa-token
  namespace: kube-system
  annotations:
   kubernetes.io/service-account.name: oke-admin
type: kubernetes.io/service-account-token
```

Execute this command
`kubectl apply -f oke-k8s-dashboard-auth.yaml`

This command will create ServiceAccount, ClusterRoleBinding and Secret.

Execute this command to view token created for auth used later.

`kubectl describe secrets oke-admin-sa-token -n kube-system`

Then execute this to deploy Kubernetes Dashboard.

`kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml`

To run it on your local, run `kubectl proxy`

It now accessible at http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

paste the token created. Have fun!

Git Untouched
Published: 2023-02-04 09:19:14

As writing tradition entails, I have to Introduce Git and explain what it generally means but this is beyond just git, this article is more about git, as I believe you already have ground knowledge about git and you are looking to get in-depths this article is centered around "Git Revert", "Git Rebase" and "Git cherry-pick".

## We start off with the git revert:
The two commands needed to perform a revert are the git log/git reflog and git revert 
```
$ git log
```
```
$ git reflog
```
The git reflog command is used to record updates made to the tip of branches. It allows to return to commits even to the ones that are not referenced by any branch or any tag also the git log while  git log  shows commits in descending order based on commit datetime.

This two commands were mentioned first because it is needed to perform a git revert command. The git revert would most likely be used when you realize that there was a bug in your last commit and you need to rectify to continue working on new tasks. 

The git revert command will undo changes in a project commit history without tampering with it. This is why you have to run the `git log` or `git reflog` command to target the specific commit you might want to revert to.

```
git revert <commit hash>
```

## Git Rebase
The Git rebase command literally combines two source code branches into one. This command takes all of the commits from the branch you’re going to rebase(eg dev-branch) and replays them onto the end of the branch you’re rebasing(eg main branch) to and after it is successful, the dev-branch will be removed.

**Steps to take while you want to Git Rebase**

- First, confirm that the head branch has no outstanding changes.
`git status`

- You checkout the new-feature branch.
`git checkout new-feature`

- We tell Git to rebase the current branch onto the main branch.
`git rebase main`

- We swap back to the main branch
`git checkout main`

- We merge the new-feature branch into the current branch, which in our case is the main branch.
`git merge new-feature`

## Git Cherry-pick
Generally, the git cherry-pick command enables you to copy a commit from anywhere in your repository and append it to the HEAD of the current branch. 

One downside to using this command is that it creates duplicate commits which creates a foggy git history. To use git cherry-pick you need to find the commit reference you are interested in and the use `git cherry-pick <commit_reference>` after you have checked out the branch you want to bring in the particular functionality referenced in the 'commit_reference' into.

Variables in JavaScript: The Fundamentals
Tags: javascript, variables
Published: 2023-02-04 08:45:34

JavaScript is a dynamically-typed language that allows developers to store data in variables. Variables are containers that hold values, which can be of different types such as numbers, strings, arrays, and objects. In this blog post, we will go over the basics of variables in JavaScript and how to use them effectively.

**Declaring Variables in JavaScript**

In JavaScript, you can declare a variable using the var, let, or const keyword. The var keyword has been used for years and is still widely used in older JavaScript code, but it is generally recommended to use let or const for declaring variables in modern JavaScript.

The difference between var, let, and const is the scope and mutability of the variable. var variables are function-scoped, which means that they are only accessible within the function they are declared in. let and const variables are block-scoped, meaning that they are only accessible within the block they are declared in.

let variables are mutable, meaning that you can change their value after they are declared. const variables, on the other hand, are immutable, meaning that once a value is assigned to them, it cannot be changed.

For example, let's declare a variable name using const:

```
const name = "John Doe";
```
In this example, we declared a const variable name and assigned a string value of "John Doe" to it. Once the value is assigned, it cannot be changed.

**Assigning Values to Variables in JavaScript**

In JavaScript, you can assign values to variables using the assignment operator =. The assignment operator takes the value on the right-hand side and assigns it to the variable on the left-hand side.

For example, let's assign a value to a let variable:

```
let age = 30;
```
In this example, we declared a let variable age and assigned a value of 30 to it. The value of the age variable can be changed later in the code.

**Data Types in JavaScript**

JavaScript is a dynamically-typed language, meaning that the type of a variable can change based on the value assigned to it. There are several data types in JavaScript, including:

- Number: Represents numbers, such as integers and floating-point numbers.
- String: Represents a sequence of characters, such as words or sentences.
- Boolean: Represents a value that can be either true or false.
- Array: Represents a collection of values, such as a list of numbers or strings.
- Object: Represents a collection of properties and values, such as a person's name and age.

You can use the typeof operator to find out the type of a variable. For example:

```
let name = "John Doe";
console.log(typeof name); // Output: string

let age = 30;
console.log(typeof age); // Output: number
```
In this example, we declared two variables name and age, and used the typeof operator to find out their types.

**Conclusion**

Variables are an essential part of any programming language, and JavaScript is no exception. In this blog post, we covered the basics of variables in JavaScript, including how to declare variables, assign values to them
How one type of file compression functions?
Published: 2023-02-04 08:28:09

I understood the concept of compression involved reducing the size of files.  Some of the benefits of this process is freed up disk space, improved transmission speed, and better secured files.  However, I never learned the “how” about the process.  Today, I learned there are different compression algorithms that execute this process.  The Lossless type of file compression stores data in efficient manner by reducing redundancy.  I found an article written by Vicky that I feel provides a great example of this process.  A text like “eeeerrrssjjj” can be reduced to “e4r3s2j4”.

Swift: Conforming a protocol to a protocol.
Tags: swift, ios, mobile, programming
Published: 2023-02-04 07:54:42

In some cases you want to conform a protocol to another protocol that defines an associated type.
```swift
protocol CollectionSlice: Collection {
    func prefix(_ maxLength: Int) -> CollectionSlice
}
```
It’s not uncommon to run into an error like this:

`Protocol ‘CollectionSlice’ can only be used as a generic constraint because it has Self or associated type requirements
`
This is because the compiler can’t make sure that the returned `CollectionSlice` will result in the same underlying associated type as the defined protocol. Therefore, we need to setup a constraint that makes sure both types are equal:
```swift
protocol CollectionSlice: Collection {
    associatedtype Slice: CollectionSlice where Slice.Item == Item
    func prefix(_ maxLength: Int) -> Slice
}
```
Implementors of this protocol are now required to return a slice of the same type as its parent collection:
```swift
extension UppercaseStringsCollection: CollectionSlice {
    func prefix(_ maxLength: Int) -> UppercaseStringsCollection {
        var collection = UppercaseStringsCollection()
        for index in 0..<min(maxLength, count) {
            collection.append(self[index])
        }
        return collection
    }
}
```

Swift: Associated types. Constraints.
Tags: swift, ios, mobile, programming
Published: 2023-02-04 07:50:23

Now that we’ve seen how an associated type could work in a real case [example](https://dev.to/sergeyleschev/swift-associated-types-example-51ea) it’s time to dive a bit deeper into the available possibilities.

Let’s continue with our example showed earlier for defining a `Collection`:
```swift
protocol Collection {
    associatedtype Item
    var count: Int { get }
    subscript(index: Int) -> Item { get }
    mutating func append(_ item: Item)
}
```
What if we want to compare the appending item to any of the existing items before inserting? We need to have a way to compare for equity.

We can do this by constraining the associated type to, in this case, the `Equatableprotocol`:
```swift
protocol Collection {
    // The associated type now needs to conform to Equatable
    associatedtype Item: Equatable

    var count: Int { get }
    subscript(index: Int) -> Item { get }
    mutating func append(_ item: Item)
}
```
