Through the internet, they get the integration and one spot result for every one of their wants. Whatever they are searching for, they get everything at a spot like [hotel bookings] (https://travelportalsolution.com/hotel-extranet/), flight bookings, holiday bookings, [bus reservations] (https://travelportalsolution.com/redbus-api-integration-or-seatseller-api-integration/), and so on. 

![API Integration](https://dev-to-uploads.s3.amazonaws.com/i/ixja2rs2sqso7h1cvc6z.jpg)


Prior to when the integration technology was not there, voyagers used to visit various web portals for various bookings like for flights they have to go to the flying site, and for hotel booking, they have to look for a good hotel site. Looking for so numerous things at a time builds the chaos, yet it was a lot of time taking too. From the travel planner’s point of view, the mode was likewise not something that could carry great benefit to them. The need for one spot to wind up all travel related explorations prompted Travel API integration. It is a stage that gives one exclusively spot to get the best travel look through the outcome. 

With this travel technology, travel agents or specialists can incorporate their site and can offer the best opportunities of the business to their clients too. Along these lines, the traveling hunter remains in his site for a more drawn out time and consequently, enormous traffic will be changed over into great business also. XML API integration gives the most ideal measurement to the travel site to draw in an ever-increasing number of voyagers towards it. This isn't at all shoddy also. Depending upon the business type and the spending travel agent can decide for Direct API, 3rd party API, and white label travel portal solution. For all these integration travel agents need to contact the best travel technology service provider that can give all this with the requirement made by the agent and is in the budget.

Python - A beautiful language without prettier!
Published: 2020-09-08 05:40:02

Prettier is an opinionated code formatter and ensures that the code I was working on is as hellish as it was not originally intended to be.

If you are working in a big team and want consistent code formatting without manual intervention(code reviews), I might recommend Prettier, but if you are working alone like myself then I wouldn't.

Prettier is available as VSCode extension which can be enabled and it automatically take cares of formatting. You could even set preference when to format the file i.e. on file save or when you paste text etc.


Now the first option is to disable the VSCode extension. I am sure this is not what you are looking for as it is pain to enable and disable the extensions every time you switch projects.

Other option is to enable Prettier only when a configuration file is present in the project. To enable this option open VSCode settings

On Windows/Linux - File > Preferences > Settings
On macOS - Code > Preferences > Settings
Search for Prettier:Require Config and make sure it is checked

Prettier:Require Config

Kubernetes - First deployment
Tags: kubernetes, devlog
Published: 2020-09-08 05:12:50

# Deploying new stuff

Start a new pod using deployments as follows:
```bash
kubectl run "<deployment-name>" --image "<container-image>" "<commands-passed-on-to-container-image>"
```
This creates 3 resources - deployment, repliac sets and finally a pod / pods. 

A deployment consists of one or more replica sets, replica sets consists of pods.
Deployment allows scaling, rolling updated and rollbacks. A replica set makes sure given number of identical pods are running, it also allows scaling.
Since deployment "manages" it's replica sets, configuration in deployment will override changes in replica set configuration made from CLI.

# Watching logs for a running pod
```bash
# Logs for a deployment
kubectl logs "deploy/<deployment-name>"

# You can use common switches like tail and follow with this
kubectl logs "deploy/<deployment-name> --tail 1 -f"
```
Logs command can only pull logs from one pod, if you have multiple identical pods running, logs will stick to just one pod till that gets terminated.
You can also pull logs for a specific pod - using get pods to get pod ID, use that ID with logs command.

# Scaling pods
```bash
kubectl scale "deploy/<deployment-name>" --replicas "<number>"
```
It'll scale no. of pods to new replicas number.

# Deleting resource
```bash
kubectl delete "<resource-type>/<resource-id>"
```
Delete send SIGTERM to shut down pod gracefully, as soon as one pod is in "Terminating" state, replica set will start a new one to match total replicas configuration. Once grace period expired, Kubernetes will then kill container in "Terminating" state, this grace period is configurable to suite variety of application lifecycles.

How to set up a free custom domain on Github Pages
Tags: javascript, webdev, beginners, tutorial
Published: 2020-09-08 04:43:06

For this tutorial I will be assuming you have already setup a site on Github Pages that's being run on the standard ***USERNAME.github.io*** domain. If you haven't done so, a quick Google search will yield lots of articles explaining the process. I'm using Bluehost as my domain provider, but the steps should be similar for any major domain provider.

## Setup in Github repository
In your Github repo for the site, navigate to the "Settings" tab. Scroll down and you will find an area for Github Pages setup. In the Custom Domain section, enter the domain name you want to use and click save.
![Github Domain](https://i.imgur.com/UEKZ7VS.png)
If you're using a static site generator, you may already have a file in your repo called CNAME. If you don't, you can create one. Inside this file, place the domain name. 
![CNAME](https://i.imgur.com/NQKTehC.png)

## Host record setup
Now open the domain provider that you are using, and navigate to the DNS section for the domain you are interested in using. 

First you will need to add four A host records. The host record for each of these is "@". The image below shows what it looks like on Bluehost. 
![A host](https://i.imgur.com/3B5bev3.png)
The four IP addresses (at the time of writing this) for each record to be added are:
- 185.199.108.153
- 185.199.109.153
- 185.199.110.153
- 185.199.111.153

Next, we need to add a CNAME record for the www site record. This will be in the format ***USERNAME.github.io***
![CNAME](https://i.imgur.com/P3zGhXl.png)

That's it! The records will probably take some time to update, so be patient. After they update you should see your site live on the domain you've provided.
Optimized Balanced Paranthesis solution in Python.
Published: 2020-09-08 04:31:25

**Problem Statement: 
Given an expression string, write a python program to find whether a given string has balanced parenthesis or not.**

**Sample Test Case** : 
**Input:** '([{}])'
**Output:** 'Yes'

Although, you have seen many solutions to this problem. For example, using stack, using a queue, and even linked list and 
using some graph algorithms too. Here, I am sharing a very straightforward and understandable strategy to solve the balanced parenthesis problem.

We can solve it by using the string's replace method.
Let begin.

 `   string = input()`
 
First, we will take the input string contains a series of parentheses.
```
> n=-1
> while len(s)!=n:
>    n=len(s)
>    s=s.replace('()','')
>    s=s.replace('[]','')
>    s=s.replace('{}','')
> if len(s)==0:
>    print("Balanced")
> else:
>    print("Imbalanced")
```

We will run the loop till length of string and n becomes equal. Inside loop, we will take string length in n so that n can store the past length. Now, we will try to replace matching brackets like [], {}, () if they are present in string with empty string. After that again, string length will be compared with past length n.

This will become equal when there will be no more matching brackets. And this condition can arise in 2 cases :
1. When the string was balanced and finally it becomes an empty string due to constant replacement.
2. When the string is imbalanced and there are no more brackets to be replaced.

If we get an empty string in the output, then we have got a balanced parenthesis string, else we got an imbalanced string.


*Hope this answer helps you in becoming a better competitive programmer. Feel free to ask any questions in the comment section and keep coding guys:)*
Tabifier Action - Convert Leading White spaces to Tabs
Tags: actionshackathon, showdev
Published: 2020-09-08 04:11:48

Want to work at Piep Piper? :man_technologist: :woman_technologist:
You must use this action in all of your repository!


### My Workflow
This action converts leading whitespaces in your repository to tabs. Richard Hendricks will be happy!

This action takes 1 optional input - `tabLength` (default value is 4 - means 4
spaces will be replaced by 1 tab. The values are always rounded up, _e.g._ 7
spaces will be replaced by 2 tabs). Note that, files inside `.github` directory
are ignored. Along with this, you also need to specify the `github_token` environment variable.

Here is an example workflow:

```yaml
name: Tabify

on:
  push:
    branches: [ master ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Repo checkout
      uses: actions/checkout@v2
    - name: Tabify
      uses: ayan-b/tabifier-action@master
      env:
        github_token: ${{ secrets.GITHUB_TOKEN }}
      with:
        tabLength: 4
    - name: Commit and push
      run: |
        git status
        git add .
        git config --global user.name "github-actions[bot]"
        git config --global user.email "41898282+github-actions[bot]@users.noreply.github.com"
        git commit -m "Tabify"
        # change the link according to your repository
        git push https://ayan-b:${GITHUB_TOKEN}@github.com/ayan-b/tabifier-playground HEAD:master
```


### Submission Category: 

Wacky Wildcards


### Link to Code

The action can be found in this repo:
{% github https://github.com/ayan-b/tabifier-action %}


### Additional Resources / Info

You can see this action in action [here](https://github.com/ayan-b/tabifier-playground).
