Get forced to wake up

Do you have a problem with your wake up time? Do you often get up too late? You deserve trying this app. Its name is Fajar Warrior Alarm, “just” an alarm app. Actually there are a lot of similar app in the PlayStore. But I choose this one for you, because it’s free (of course the others are free as well though), free of charge and free of ads, that’s the point. I hate apps that show ads so often. And luckily, there is still a generous developer who doesn’t take the user’s freedom to not showing ads in his app. I mean this alarm app.

So, what else that makes it awesome? The challenge to stop the alarm voice. You couldn’t stop the alarm, unless you type the exact same sentence (a hadith) in the input it has. Actually I searched for “math alarm” when I found this app. But unfortunately it contained ads, so I looked for another app instead. And it led me to this Fajar Warrior Alarm.

The idea is similar to the app I wanted in the first place. It won’t stop the noisy alarm until the user type in some expected text. It causes the user to use his/her fully consciousness when typing the answer. And hopefully make the user totally wake up. So curious about it? Just install it and try it on your phone. Good luck.

QR Code Scanner with Qt Framework + OpenCV

I need a program for scanning QR code and processing the data. For this purpose, there are several libraries which can help saving my time for developing it. For instance, ZXing library, or ZBar. For web developers, there are also corresponding library for scanning QR code, that are both client side (JavaScript) and server side (PHP).

Making Kinetic Typography in Linux

Kinetic typography is an animation technique for moving text in certain ways. It became quite popular since a few years earlier. There are so many tutorials out there how to do kinetic typography. Almost all of them are created with After Effects (AE).

As a part of OpenSource community, I have once wondered, was there exist a similar program to do kinetic typography that runs on Linux? The answer is, yes of course, but not as powerful as AE. Actually, I’ve found Synfig Studio that has a close functionality to AE to produce kinetic typography. But, basically Synfig is a 2D animation software. Therefore, I cannot compare it with AE, after all.

TL;DR, this is a tutorial I’ve found in Youtube to do kinetic typography in Linux

HTML5 App for Desktop Using Qt WebKit

Qt WebKit HTML5 App
Qt WebKit HTML5 App

It’s been a long time since the last time I wrote about Qt programming. This time I’d like to share my recent activity on developing the desktop version of my Android webapp, Hafal Quran. You can download it from Google Play Store by clicking this badge:
Android app on Google Play

My purpose is that the app can run on most platform. So it led me to choose HTML5 approach. And finally I come up with the app website which everyone can play it on http://hq.amzone.web.id. The Android app is the first platform-specific release of Hafal Quran.

While it looks like already reaches the final version, it actually lacks an important aspect, i.e dis-connectivity. We have to connect to internet to play it. Of course we cannot play it when go offline. So now, I continue its development to the next step: offline mode.

The first development should be focused on the Android version, as the users of mobile devices are the most and growing. But for now, I will make the offline version for desktop first. In this case, I choose to deploy it for Ubuntu Linux distro and the derivatives, particularly Grombyang OS Edu.

Technical overview

I utilize Qt framework for the development because I have some experiences in it. Besides, I decided to use Webkit as the engine of the app. And actually it is part of Qt framework itself. Webkit is the infamous engine for most popular browser, including Safari, Chrome, and even Opera.

But unfortunately, QWebKit module is now being deprecated since Qt 5. And it is now superceded by QWebEngine module. So, for now, I will still use QWebKit module of Qt4.

The drawbacks of using Webkit is probably about the memory usage. Since Qt modules are quite greedy in terms of consuming RAM.


FYI, the Android app was one of 50 apps that were selected at Finding Top50 Local Apps event, which was held by Baidu Indonesia last year.

KDE Connect, Link Your Android to Linux Box

[Versi bahasa Indonesia ada di halaman 2]

Recently, I had a chance to try out KDE Connect. It has KDE in its name, but you can try it on other DEs. Of course with some limitations, i.e Dolphin’s right-click menu for sending files may not available on another file manager. (I haven’t try it on another DE, though). To link your Linux to Android, you need to have KDE Connect app installed on your Android and Linux as well, and connect both devices to the same network.

You can read all about KDE Connect in its developer’s blog: https://albertvaka.wordpress.com. And these are my screenshots of KDE Connect in action:

Nokia Asha 210 dan Streaming Radio Online

Ikon MFRadioTernyata sudah setahun lebih saya punya hape Nokia Asha 210. Waktu itu pertimbangan beli hape yang pertama adalah harga, yang kedua kualitas. Yang ketiga dan seterusnya saya lupa. Ponsel Android dengan harga yang sama sebenarnya sudah banyak, tapi spek-nya kecil, dan tidak memenuhi pertimbangan nomor dua. Tahu sendiri lah.

Pada saat itu saya memang belum ingin punya Android. Dan sekarang pun sebenarnya masih sama, kecuali untuk develop aplikasinya. Untungnya saya tidak perlu punya Android untuk develop, karena sudah ada yang bersedia meminjamkan kapan saja. 🙂
