I love lambda expression. Whether it's in Java, Kotlin, or Javascript (arrow function). It helps me remove verbosity from my code

Just like async/await in Javascript and C#, Kotlin Couroutines is trying to make asyncrhronous programming easier by enabling you to write async code with imperative style

There's an error in your Android build and it points to your annotation processing code. But, you can't debug it. Here's how to do it.

Getting a Pull Request (PR) from a Forked Repository in Github can be quite confusing. Here I put a note to self about the behavior that apparantly I keep forgetting.

I repeteadly googling about the ABI Jar implementation in Gradle when in fact, Kotlin has the feature built-in with different name

So this is my new blog, it is a bit different from the previous one. Well technically this is a lot different from the previous one

Sometimes, we need more than one query to execute in one operation. Let's say you have to replace an item.

Android Arch's Room - Transaction

On the previous post, we already discussed the basic Room from AAC (Android Architecture Component). In this post, we're gonna explore the how to create a relationship between tables

So, on the first post we already have an introduction or more like a sneak peek to Room data access object code. Let's get our hands dirty now!

Android Arch's Room - Getting Started

My first reaction when Android Architecture Component is out is just **meh..** I mean come on, the ViewModel is heavily tied to Activity and Fragment and basically i don't need it because i use Conductor…

On the previous post, we already discussed how your view should have its own model. We also have discussed how you can make a simple redux-like state machine in Kotlin.

On the last ADB meetup, we have a conversation about what framework we usually use in creating a REST API. Then, Adonis.Js is being mentioned. I know Adonis but haven't got a chance to test it, so let's test it now!

After reading a bunch of unidirectional data flow, Cycle.js's MVI and this article about implementing MVI in Android by Hannes, I'm convinced that this is how I should write my code from now on.

Simple State Machine

Not so long ago, on my Android's MVP architecture, my view layer does not have a model. The view only renders what the presenter tell them to do which is good because then, we have a passive view. But, there's no representation of the view itself.

A Model for Your View

Last Saturday I was attending a workshop for Spring Boot in Makers Institute Bandung. The prerequisite for the workshop is we have the tools installed on our private machine. Besides the obvious Java, we also have to install MySQL.

Seeing FizzBuzz implementation in Clojure with clojure.core.match makes me wondering if Kotlin has the same pattern matching capabilities or at least some resemblance in the way of doing matching.

Suppose you want to test some Kotlin code, but it is too simple for you so you don't want to create a project in your IDE and it also too complex to put it in your REPL

I think we already know that the domain that we use to access some website is just a masking to IP(s). All that fancy name like this blog will be translated to IP by the DNS. But how we can override it?

Domain Name Resolution with /etc/hosts

If you're familiar with OOP then you must be familiar with constructors. A constructors is a special method of a `class` that initialize an object of that type. Simply put, a constructors is a function that return your object.

Kotlin 101 - Constructors

There is some code that we write everywhere. It doesn't have **state** and usually small enough to become a `class`. We often call it a helper function and in Java we used to save it in some `*Utils` class.

Kotlin 101 - Extension Function

Often times we don't want to expose our server IP address to public. We just want to access our domain address.

HTTPS make the internet better and safer. It allows us to communicate securely in insecure channel such as public Wi-Fi or Internet Cafe.

So we already create `Interface` in Java and convert it to lambda with in Kotlin through SAM conversion. How about `interface` in Kotlin? As the previous part suggest, currently there's no SAM conversion in Kotlin interface.

What will you do if you want to test some Kotlin syntax?  Chance you are opening your favorite IDE or text editor (not mentioning `vim` or `emacs` user in here) are very likely.

Experimenting Kotlin without Editor

Although a lot of my friends and colleagues use jsoup, i never had a chance to use it. It's my brain default to not choose Java as the language for parsing HTML.
