Bitcoin mining - a rookie experience

Happy New Year

It's my first blog post in year 2018 and it's a new technology.

So it's crypto currency time. Wherever we look it's bitcoin and altcoins. After some thought i decided to try the blockchain. Just like any other technologies i used in the past, i decided to go for something small and easy one. Mining.

Before understanding anything about blockchain, i tried mining. Yes I know it's not profitable one. but decided to go for it just to have some beginning.


So everywhere i looked for mining, it's always high-end GPU/ASIC. I don't have a decent CPU with me. And it says CPU mining is not profitable. Okay. I agree. And i still went for CPU mining. Just because i would like to start taste the bitcoin.


So  we need some wallet for keeping my precious currency. Am from India and i found ZepPay . It's a mobile based online wallet. Oh, so there is online and offline wallet. Do i need to go for offline wallet which is more secure? What i am go…

Angular4 - primeng, ngx-bootstrap

In previous post we tried to create module, component and routing. Lets look into how to add third party libraries.

You could check out the code from here.
git checkout -b part3.0 origin/part3.0
In Angular4 adding third party libraries is pretty easy. Install using npm and add the module. Its one of my most loved feature in Angular4.


PrimeNG is one of the most used and most popular Angular4 library. It consists lot of components and its easy to setup and use. Besides it does have a good team working behind this library. In my experience it's one of the fast developing library.
To install PrimeNg run

npm install primeng --save
npm install font-awesome --save
PrimeNg needs font awesome for icons . Unlike any other libraries , PrimeNG had separate module for each component, which helps to include only selected component in the bundle.
Lets include styles for the components. In .angular-cli.json add

"styles": [ "../node_modules/bootstrap/dist/css/bootstrap.min.cs…

Angular 4 - Modules, components and routing

In the previous post we created a new Angular 4 project. Lets check the how to add modules, components and routing.

You could check out the code from here.
git checkout -b part2.0 origin/part2.0
We are going to use bootstrap styling . So lets add bootstrap in our aplication . We are going to use only styling not the components.

npm install bootstrap@3
We need to add the bootstrap stylesheet in tha .angular-cli.json.

"styles": [ "../node_modules/bootstrap/dist/css/bootstrap.min.css", "styles.css" ],
Our first Module

Lets add a new module employee. Inside "src/app" run

ng generate module employee or
ng g m employee
Wait we are going to lazy load this module , so we need routing inside the module, right? So we are going to create the routing also.
ng g m employee --routing
Time for component

It will create new employee module with its own routing.lets add a component for listing the employee. So inside employee folder run

ng g c empl…

Angular 4 - The Beginning

When i first started using Angular 2 its in beta. Getting started with Angular is pretty easy. The team provided an awesome cli-tool which will help to create, develop, test and build the Angular project easily. We need to install the angular/cli (Formerly angular-cli) globally. Latest angular/cli(1.1.2 at the time of this writing) will create an Angular 4 project.

npm install -g @angular/cli
Suppose you need to create an Angular 2 project. What will you do? NOrmally what i will do is will install rc4 version of angular cli and create a new project, which will by default create a angular2 project. Then later will update to latest cli and the project will work smoothly in latest cli,

npm install -g @angular/cli@1.0.0-rc.4
So that's all about angular/cli. You could check out detail in here.

Lets create an application and try it. For creating new application run the following command.

ng new ngApp
This will create a new application and it will install all the dependencies . Do you kn…

Angular - 4 year road map

AngularJS is one of the most popular JavaScript frameworks in the web. The Google developed framework is considered as one of the easiest framework to kick start a project. Two way binding and the dependency injection is the highlight of this framework.
My journey with AngularJS started about 4 years ago. Then popular ver1.4 amazed me in its capabilities. Developer like me, coming from Actionscript and plain old JQuery , AngularJS is a good option to kick start a project. It give me the confidence in JavaScript world, and from then I have tried lot of framework and tools from JavaScript itself like requireJS, webpack, etc. I did projects in Angular from 1.4 to the current 2.0, and trying to upgrade to the latest 4. Angular has now become one of the fastest growing framework. The journey starts with 1.4
One of the stable and mostly uses version. Started working on this for small projects and it seems easy for development. Dependency injection and two way binding seems quite interesting. …
