Virtual Photoshoot

As its name, the photoshoot will be performed where both photographer and talent are not physically at the same place. Yes picture will be taken from the screen while the talent will be on their phone/any camera. And yes, the image quality won’t be better than the screenshot! Then what? Personally I found that it is not the detail of the face or the dynamic range of the picture but it’s the link between photographer and the talent themselves. It still a work with directing, capture the moment, and acting!

Parse Excel with Kotlin

I want to share how to parse excel files using kotlin and apache poi java lib. repository can be found here. This example will parse a sheet with several cell type (number, string, date). The basic ideas are:1. get the Workbook instance by instantiating XSSFWorkbook(file: File)2. get the Sheet instance by call workbook.getSheetAt(idx: Int) or workbook.getSheet(sheetName: String)3. traverse every rows in the sheet by call sheet.getRow(idx: Int)4. traverse every columns in the row.

Chat Analyzer

Hi, today I want to share about whatsapp chat analyzer. You may curious about who is more often to chat, is it you or him/her, what is the most word you type, and how long you usually type a sentence to your friend.

How do life experiences shape our values?

We all experience life, but we don’t all live life for experience. I used to simply exist. I used to take what was given to me, positive or negative. I believed to be the way of this life. However, I stumbled across some interesting wisdom in a book called: Man’s Search for Meaning. It allowed my existential thinking to be brought to the surface, and it gave me permission to be me and take control of my life. Then a question surfaced from this new understanding: How do my life experiences shape my life? And Can I determine how I will experience life all together? I got some interesting answers from these questions. Here are the 3 ways life experiences …

Android Dependency Injection Using Dagger 2

Dagger 2 is a dependency injection library that relies heavily on annotation preprocessing to automatically generate a series of classes that provide dependencies to various parts of your application. The preprocessing occurs as part of compilation. The class files that are created are human readable — some are meant to be referenced just like any other java classes, others should just silently do their magic in the background. Dagger 2 uses the following annotations: @Module and @Provides: define classes and methods which provide dependencies @Component: enable selected modules and used for performing dependency injection @Inject: request dependencies. Can be used on a constructor, a field, or a method Module and Providers Get your bean ready with @Provides annotation on method level and remember to …

Talk to Pi

Raspberry Pi absolutely fit to become a “server”, at least mini server that can serve your need. But, there’s come a problem, how to connect my Pi from internet??  This question must come to most people who planned to create a smart things in their home. Sometimes we need to connect your Pi remotely while we’re outside home. There’s some solutions to solve it like VPN, ton of works websocket, port forwarding with extra prerequisites, remot3.it and dataplicity. Here i will only talking about dataplicity since I’m using it and it’s better than any solutions available above (Please let me know if you found a better solution doing this). Actually this kind of article also available here in raspberry pi help documentation. As you …

Initialize your Raspberry Pi

Ever wonder to have mini PC that probably just enough to become 24/7 server and even clustering them together? Likely Raspberry Pi could become one of your choice. Raspberry Pi is a computer powered by ARM micro processor and can run Linux in it. Unlike MicroController, this one is much powerful in terms of processing power but I cannot say  that Raspberry Pi is better than arduino and other microcontroller peripherals. They’re not comparable since they’ve made on different purpose. There’s considerations to take before you buy one : Purpose of the device Power usage Community support Features Difficulty level to achieve your purpose There’s more than raspberry pi and they may be more powerful too. But due to its …

Myoclonic jerks

This refers to that strange feeling when you lie down to go to sleep, and as you start to drift off your body is jolted for a second by what seems like an electric shock. In this moment, all of your muscles spasm so strongly that you almost fall out of bed, and you wake up straightaway. This phenomenon is the result of the fact that when you begin to fall asleep, the frequency of your breathing rapidly falls, whilst your pulse slows down only very slightly and your muscles are relaxed. Amazingly, your brain interprets these developments as heralding death. So it tries to save you by giving you a jolt. source: https://brightside.me

What is Refrigerator

Prior to the invention of refrigerators, food preservation imposed serious constraints. The best options were to suspend food in rivers, wells, or at the bottom of lakes, and absent these tactics, stable foods were heavily salted, spiced, pickled, or dried to prevent bacterial growth. With the industrial age, we began to understand thermodynamic cycles and—through an interplay of pumps, valves, and heat exchange—learned to cool food to arbitrary temperatures with the refrigerator cycle. We just saw that the refrigerator carries out a cycle to move heat out from the food compartment and into the room. This occurs via three main components: A pump that compresses gas. A valve that expands gas. Radiators that allow gas to exchange heat with the …
