Start of my  freelance career

In 2006, I got admission to pursue my Undergraduate degree. One of the senior students of my university told me about; He said I can get  freelance works from there. For the first time, I heard about it. I visited the site and signed up. At that moment, I didn’t know what is freelancing, what to do and how to get paid. In fact, I was doubtful and curious. Started to look for job and bid on the jobs that I could accomplish. Fortunately, within few days, one client knocked me and awarded a simple project. I first project was to find out articles online about time management. I was very excited and completed the job with care. She was very happy with my job and paid me full amount. She gave a very good positive review with 5 start rating.

How to load HTML code or file in UIWebView using swift?

Let me tell you my one secret about iOS designing. Sometime, in our design, we have to use table views / grids for example bank statement. If you are familiar with iOS designing and auto layout, you already know how difficult it is to design complex tables or grids. In such situations, I use UIWebView. In background I prepare an html source code, then display the code in web view. Today I’ll tell you how to load source codes in web view using swift. After that, I’ll show how to load local html file in web view.
 1. Create an iOS application in Xcode.
2. Add a web view in the View controller of the storyboard

UIWebView3. Drag and drop web view’s IBOutlet to our ViewController.swift

4. Write a method to load string in UIWebView

In the above code, we created a constant (variable) htmlCode and wrote some html codes there. In the second line we loaded the htmlCode in our web view.

5. Call the method in ViewDidLoad:
Run the code and see what have you done.

Load local HTML file in UIWebView

Writing source codes in ViewController is painful and time wasting. Better approach is to create html file in Dreamweaver or Sublimetext or any other html editor. We’ll save that file in iOS project and load in web view. So, let’s begin our work.
  1. Create an iOS application in Xcode.
  2. Add a web view in the View controller of the storyboard
  3. Drag and drop web view’s IBOutlet to our ViewController.swift
  4. Create an html file using Sublime text or Dreamweaver or any other html editor. Save the file in a folder and open that folder.screen-shot-2016-09-20-at-10-06-44-pm
  5. Drag the file from folder to our Xcode’s Project Navigator. After you drag and drop, a dialog box will appear. In the dialog box check the “Copy items if needed” checkbox.
  6. Write a method to load local html in UIWebView
  7. Call loadHtmlFile() method in viewDidLoad method:

You can download the whole project from github

How to load HTML url in webview using swift

Well, it’s very easy to load HTML url in a web view using swift. Suppose we want to show in a web view in our iOS application. We’ll do that in 4 easy steps. Let me tell you them step by step.

  1. First create an iOS application in Xcode.
    Add a WebView in the ViewController of the storyboard. Do not forget to add auto layout to WebView, otherwise you may can’t see the WebView.screen-shot-2016-09-13-at-10-45-27-am
  2. Drag and drop WebView’s IBOutlet to our ViewController.swift and name it: webView
  3. Now we’ll create a new method in ViewController.swift
  4. In ViewDidLoad method call loadUrl method:

Run the app. You will see google website is loaded.

If you use any non-secure url, Xcode will log an error in error console.

App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app’s Info.plist file.

The urls that start with http instead of https is called non-secured url. Due to security issue, iOS doesn’t load non https urls.
In such case we’ve to add some values in our Info.plist.  

Fix the issue of “App Transport Security has blocked a cleartext HTTP”


a. Open Info.plist file from left panel (File explorer).


b. Click on plus button (+) of any top level row. I’ll click the plus button beside Bundle Identifier.


c. A new row will be created. Type “App Transport Security Settings”  (without double quotes) in the row (key column) box. Hit Enter. It’s type should be a dictionary.


d.  Open the App Transport Security Settings row by clicking on Arrow head at the beginning of the row.


e. Click Plus button next to the row of “App Transport Security Settings”


f. In new row type “Allow Arbitrary Loads” (without double quotes)

g. Make it’s value to Yes.

Run the app again with any non-https link e.g.

Big Data for Banking Sector

In the field of nanotechnology, scientists of different fields such as physics, chemistry and biology work under the same roof. By the same way, in the field of Big Data, not only programmers, also statisticians, decision makers, system admins all work together. Big data is taking our modern computer based society to a new height. Still it’s the beginning of the journey and has started to reveal it’s possibility to different fields, such as social network, marketing, health care, law enforcement as well as banking and insurance Sector. Today we’ll explore the possibilities of big data in banking and financial sector.

Why Big Data in Banking Sector?

Big data deals with…
1. large amount of data (Volume),
2. coming from different sources and in different formats such as transaction data, customer photo, CCTV images (Variety)
3. that needs to be processed very fast (velocity).

Banking data has all these 3 properties. That’s why big data fits in banking sector.

There are 5 major areas of implementing Big Data in Banking sector:
1. Fraud Detection
2. Analyze customer sentiment and feedback
3. Analyze transaction history to discover trends around the year
4. Analyze customer’s spending history and behavior to offer personalized product
5. Customer Recognition

1. Fraud detection:
Currently banks detect frauds depending on ip address, unusual login time and “using wrong pin multiple time” etc. Big data changed the process of fraud detection. By analyzing large amount of data, applying algorithm and fraud pattern, it has become possible to detect and prevent frauds or unusual activity instantly.

2. Analyze customer sentiment and feedback:
It is easy to get new customers. But retaining them for long time is challenging. So it is important to analyze customer’s complain, suggestion, satisfaction and make decision based on analysis result. For example improving a service that is performing poor and dissatisfying customer, relocating ATM booth etc.

3. Analyze transaction history to discover trends
Banks have large amount of transaction history. By analyzing those data, we can discover trends of spending and savings of customers. We can find when and where users spend more amount of money. For example, before festivals customers spend more in shopping malls. By discovering these trends banks can offer better services for it’s all customers.

4. Analyze customer’s spending history and behavior
In this case, banks analyze single customer’s transaction history and behavior. This analysis helps management of banks to offer personalized products. For example, banks can offer dual currency products with benefits to the customers who travel frequently abroad. Banks can also offer special discounts to customers who make online transactions more often.

5. Customer Recognition: It is time consuming to recognize a customer when he or she goes to bank to withdraw money or perform other transaction operation. By using realtime analysis power of Big data, banks can analyze photo, signature, voice and behavior to recognize customer. This can save time and let bank stuffs server more customers.

Benefits of Cloud Server Hosting

Cloud Server Hosting

Cloud computing is expanding and becoming popular day by day. In the near future, most of the websites – if not all – will be hosted on cloud servers. Because, cloud server hosting has benefits over traditional single servers. It has some disadvantages too.

  1. Cloud server hosting  is Cost effective: In cloud server hosting, pricing is calculated based on CPU, RAM, storage any other resource you’ve used. In current scenario, we buy 10 GB space, use less than 1GB. For example,  my one client runs a local newspaper. He uploads news with images everyday. He unlimited space. After one year, we found that, it took only 1 GB space. So in cloud server you just pay for what you’ve used.
  2. Cloud server hosting is scalable: Suppose you have a online training website where you upload training videos and let subscribed members watch those videos. After 6 months, you found that the business is growing, number of members doubled and they are requesting for more videos. If you have bought a traditional hosting server with limited space, then you’d have to change the hosting package to upload new videos. In cloud server hosting, we don’t have to worry about it. If your business grows, needs more space and bandwidth cloud server will not stop you. You can use as much resources as you need.
  3. Security of cloud server hosting: Most of the cloud server hosting providers implement standard security features. However, responsibility for security doesn’t only depend on cloud hosting provider but also end users or customers. So, both parties should be concerned about it.
  4. Location of server: Some cloud hosting providers give you the opportunity to choose the location of your server. e.g, If your website’s most visitors are in Asia, you can select Singapore or Japan region. It helps to reduce server pinging time as well as increase performance slightly.


  1. Cloud servers have downtime, which is also true for shared hosting
  2. Cloud server’s performance may be slower than highly configured dedicated servers.
