How to connect bluetooth keyboard to Nokia 5800

By following these steps I got my Logitech diNovo Edge keyboard connected to my Nokia 5800. I can browse through my phone with the keyboard, surf the web. It was all thanks to this webpage that I got everything working.

The first step is to download and install an application that will handle bluetooth keyboard connectivities.

• Download the install file to the application in this address: http://nds1.nokia.com/phones/files/software/Nokia_Wireless_Keyboard_S60_31.sis (I browsed to this address directly from my phone, but you can also download it to your computer first and then transfer it to your phone).
• Install it

The second step is to set up the connection between the keyboard and the phone. This is done by a process where the phone gives a passcode to the keyboard in order to have permission granted to set up the connection.

• Open the installed application in Applications in the main menu.
• Select Options and choose Find keyboard
• If the phone asks if you want to activate bluetooth, select yes.
• The phone will now try to find the keyboard, select OK.
• Select More Devices.
• Select the keyboard.
• Select a passcode of your own choice (for example 123) and select OK.
• Type the same passcode on the keyboard and press Enter key.
• Select the language layout of your keyboard.

You can disconnect the keyboard by going back to the application, select options and disconnect keyboard. I also turn off the bluetooth by clicking the bluetooth icon in top of the main screen and switch Off.

Android: TicTacToe

During my summer vacation I took the opportunity of learning how to create application for the Android platform. A really great development guide is their own official guide. Anyway, after reading through the guide I was eager to try creating something, and the result is Tic Tac Toe for Android. :)

The download link is here. I have only tried running it on an emulator, so I would appreciate any feedbacks on running the actual hardware. It was fun creating a simple application such as this and I'll be aiming something bigger later on. Be sure to write comments about my application.

SSH: Changing SSH keys

I was thinking of changing my SSH key into a new key with no password, that way I would be able to make cron jobs that would remotely access my NAS for backup purposes. But after generating a new key ($ ssh-keygen) and transferring my new key to the NAS a message was always displayed every time I'd log in. "Agent admitted failure to sign using the key.".

• cherng@computer:~$ ssh cherng@server.com
• Agent admitted failure to sign using the key.

The solution that I found from this site was to make the computer forget the old identity of the former SSH key. This was done by running ssh-add -d, renaming the id_rsa and id_rsa.pub temporarily and log into my NAS, then log out and lastly change the names back to original.

• cherng@computer:~$ ssh-add -d
• cherng@computer:~$ mv .ssh/id_dsa .ssh/id_dsa.bak
• cherng@computer:~$ mv .ssh/id_dsa.pub .ssh/id_dsa.pub.bak
• cherng@computer:~$ ssh cherng@nas
• cherng@nas:~# exit
• cherng@computer:~$ mv .ssh/id_dsa.bak .ssh/id_dsa
• cherng@computer:~$ mv .ssh/id_dsa.pub.bak .ssh/id_dsa.pub

After doing all the steps above, the new SSH key should work. I hope this helped, because it did for me.

What music am I listening to right now?

If you look on the menu to the right you will see a list containing recently played songs. Last.fm features a widget which shows the latest songs I've been listening to. It's just something cool that I thought would be nice to have on my blog. :)
