SSH Login problem after upgrading Harmattan N950 to PR 1.1

Recently PR 1.1 upgrade notification poped up on my N950 developer device and as normal reflex I started upgrade.

This time update was supported over wifi and upgrade gone well, with some low memory warning which we can safely ignore.

But after upgrade I found that I could no longer ssh to device with root account. 

Root login via ssh (password or public key) is now disabled with PR1.1. But If you still want to login using ssh then you can try following work around.

You need to unlock developer account and set password for developer account.

To do this, on your device's terminal type devel-su (to access device as root) and then type "rootme" password.

devel-su

Now you have root access to device. Now you need to set developer account password, using following command.

passwd developer

Enter new password for developer account.

Now you can ssh using developer account and new password.

ssh developer@192.168.2.15

now if you wish to have root access you can type devel-su command,

devel-su

Now you will have access to root account. Following is output from my terminal.

ssh developer@192.168.2.15
developer@192.168.2.15's password: 


BusyBox v1.19.0.git (MeeGo 3:1.19-8+0m6) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/home/developer $ devel-su
Password: 


BusyBox v1.19.0.git (MeeGo 3:1.19-8+0m6) built-in shell (ash)
Enter 'help' for a list of built-in commands.

Audiobook Reader now available for N9 / N950 ( Harmattan ) on Nokia Store

I recently updated my Audiobook reader application for N9 Harmattan platform. It is also supported on N950. You can download it from Nokia Store from here.

For those who dont know about this application, Audiobook reader is simple Audiobook player which lets you add audiobook with single large audio file or folder with audio files for each chapter. It automatically bookmark the last position of audiobook and resume playback from that position. It also allow to add custom bookmark and playback from certain chapter from Audiobook.

For N9, I completely reimplemented UI layer to give native look and feel. For this version I am also showing book cover image, downloaded from AWS to give more feel of book.

Same as N900 version, this version also support custom bookmark support and chapter selection support. Volume can be changed by using Hardware key.

Enabling Booster support for QML applicaion in Harmattan

Recently I added support for Booster for My QML application. Its quite easy to add booster support for existing QML or new QML application.

I am wiring down my experience here in hope it will help someone.

The QML booster reduce application startup latency by creating instances of QApplication and QDeclarativeView the classes in MDeclarativeCache.

To use this class you will need to add following header.

#include <MDeclarativeCache>

And then you will need to use QApplication and QDeclarativeView class instance provided by MDeclarativeCache. Following code shows how that can be done.

QApplication* app = MDeclarativeCache::qApplication(argc, argv);
QDeclarativeView* view = MDeclarativeCache::qDeclarativeView();

To enable booster and link with it properly you need to add following line in to your Qt project (.pro) file.

# enable booster
CONFIG += qt-boostable qdeclarative-boostable
LIBS += -lmdeclarativecache

If you are planning to use applauncerd to launch application then you will need to use Q_DECL_EXPORT macro in front of main function from "QtCore/QtGlobal" header file as shown in following code.

#include ≶QtCore/QtGlobal>

Q_DECL_EXPORT int main( int argc, char* argv[] ) {
}

You will also need modify include path in your pro file in order to locate header file properly.

INCLUDEPATH += /usr/include/applauncherd

And finally in your desktop file, you need to use --type=d to launch application using booster.

Exec=/usr/bin/invoker --single-instance --type=d /usr/bin/appname
