Advantage and Disadvantage of BlockChain

What is BlockChain Advantage and Disadvantage?
What is BlockChain Advantage and Disadvantage?

Blockchain is a public record of transactions. It’s also distributed, so instead of one person controlling everything, there are thousands of computers around the world connected to a network, and these thousands of computers together come to an agreement on which transactions are valid.

A blockchain, originally block chain,is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data.

Add Multicolor TextView in your Android project

Android TextView is capable of showing text in your Android app and previously we discuss how to add rotating animation with TextView. This tutorial explains how to use MultiColor TextView in Android application.

Multicolor TextView in Android

This is a simple library to display text with multicolor. Let see some demo of Multicolor TextView library:

How to Install Multicolor TextView?

Add to your app module build.gradle

compile ‘com.lombokcyberlab.android.multicolortextview:MultiColorTextView:1.0.0’

Do you know : Android MVP Pattern Example

For gradle 3.x

implementation ‘com.lombokcyberlab.android.multicolortextview:MultiColorTextView:1.0.0’

For maven add to your pom file:

<dependency>

<groupId>com.lombokcyberlab.android.multicolortextview</groupId>

<artifactId>MultiColorTextView</artifactId>

<version>1.0.0</version>

<type>pom</type>

Nothing Type For Kotlin Programming

A colleague approached me a while ago and asked me a question about Kotlin. What was this “Nothing type”, and what was it used for? I did not really have a good answer for him at the time.

Since then, I’ve found my answer.

In mathematics, bottom (often denoted as _|_) represents the absolute minimum value something can hold.

Nothing type has no instances. You can use Nothing to represent “a value that never exists”: for example, if a function has the return type of Nothing, it means that it never returns (always throws an exception).

Previously shared Kotlin post:

  1. Top 12 Advanced Kotlin Tips For Pro Developers
  2. Kotlin Parcelize – Developer need to know
  3. Create Firefox Extension Using KotlinJS

When we’re talking about types, we can think of Nothing as being the absolute bottom (leaf) object of any type hierarchy.

What we can see in this diagram (figure 1) is that Nothing is the opposite of Any. While every object you will work with in Kotlin implicitly extends Any, so to does Nothing implicity extend any object that exists. This makes Nothing the ‘dual’ or opposite of Any.

So, why is this useful?

Best 10 Kotlin Tips You must Know

Advanced Kotlin Tips on writing good Kotlin code and using what the language has to offer. There are many benefits of using Kotlin; it is concise, safe and most importantly it is 100% interoperable with Java. It also tries to solve some of the limitations of Java.

Top 12 Advanced Kotlin Tips For Pro Developers

Now is a good time to consider Kotlin for your next big feature or project, because Google finally announced it to be a first-class language for writing Android apps in Google I/O 17.

So here are some advanced Kotlin tips to help you start making use of what the language has to offer and writing good Kotlin code.

1. Singleton

Implementing lazy loaded and thread-safe singletons in Kotlin is really easy, unlike Java where you would have to rely on the complex double-checked locking pattern. And although Java enum singletons are thread-safe, they are not lazy loaded.

You must see this : Kotlin Parcelize – Developer need to know

  1. object Singleton {
  2. var s: String? = null
  3. }

Contrary to a Kotlinclass, an object can’t have any constructor, but initblocks can be used if some initialization code is required.

  1. Singleton.s = “test” // class is initialized at this point

The object will be instantiated and its init blocks will be executed lazily upon first access, in a thread-safe way.
