The pgp.net keyservers seem to be not really reliably these so I was unable to use them to retrieve the required Public key for validating the repositories’ packages.

this resulted in the following error:

Reading package lists… Done W: GPG error: http://download.opensuse.org ./ Release: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY BED1E87979EAFD54 W: You may want to run apt-get update to correct these problems

to resolve this problem just download the key directly  from the repository

wget http://download.opensuse.org/repositories/security:/
OpenVAS:/STABLE:/v4/Debian_5.0/Release.key

and import the key manually

apt-key adv –import Release.key

update your package lists

apt-get update

and it should work without problems.

store your settings in a file e.g. ~/.ec2/eu-settings

export EC2_URL=https://ec2.eu-west-1.amazonaws.com
export EC2_REGION=eu-west-1

and e.g. ~/.ec2/us-settings

export EC2_URL=https://ec2.us-east-1.amazonaws.com
export EC2_REGION=us-east-1

now we define two simple aliases as shortcuts to these settings.

# alias eu=’source ~/.ec2/eu-settings’
# alias us=’source ~/.ec2/us-settings’

calling ‘eu’ or ‘us’ from shell will now switch the regions for you.

you may check that it worked by typing env and noting the values for EC2_URL and EC2_REGION.

These two aliases will – for now – only work in your current login session. To persist the setting, just do the following…

Persisting the aliases in /etc/bash.bashrc

edit /etc/bash.bashrc (in debian – this might differ a bit in other linux distributions)

# vi /etc/bash.bashrc

add

alias eu=’source ~/.ec2/eu-settings’
alias us=’source ~/.ec2/us-settings’

below anything that is written there. And call

# source /etc/bash.bashrc

The aliases should work as previously, but will now be available after a system restart or new login to your machine.

Check again using env if you want to verify everything worked correctly.

As a prerequisite you should have already registered an account with justvoip.com or another BETAMAX service of your choice.

First you have to get the current Version of the VoIP Settings (V.3.0 at the time of writing) from Nokia which is, or at least was not bundled with my handset.

Download it here

Install the VoIP Settings Manager.  You will find it after installation in Menu > Control Panel > Net Settings > Advanced VoIP Settings. Open the Settings Manager and create a new SIP Profile with the following values:

Profile Name: justvoip
Service Profile: IETF
Default Destination: Internet (I am using VoIP via my Home-WLAN)
Default Access Point:  none
Public Username: sip:YOURJUSTVOIPUSERNAME@justvoip.com (Note: “sip:” will always be added automatically)
Use compression: No
Registration: When needed or always on (choose your preference)
Use Security: No

Proxy & Registration Server have identical(!) values:

Server Address: sip:sip.justvoip.com
Realm: justvoip.com
User name: YOURJUSTVOIPUSERNAME
Password: YOURJUSTVOIPPASSWORD
Allow loose routing: Yes
Transport type: UDP
Port: 5060

After setting up the profile sucessfully, you will be able to activate VoIP from the Homescreen within the same menu, where you activate WLAN scanning. Just select ‘enable justvoip.com’, or how you called the profile, to turn on VoIP. Doing so the VoIP icon appears on your homescreen (Phone with a globe). Selecting a contact  will now feature “Internet call” beside the normal “Voice call” option.

I have just made use of this residing in my home WLAN. Possibly you can also turn VoIP on using a UMTS connection.

Good luck setting this up on your E52 & Happy voiping!

This post in the Nokia Forums helped me setting this all up – please have a look for yourself  if you like.

Cakefest 2009 was held from 9th-12th July 2009 in Berlin. Luckily I was able to attend the two day conference part of it on Saturday and Sunday. The crowd was really international. People from all over the world gathered – even folks from Australia and Japan joined the event. The bakers were overall very friendly and helpful – the talks really great! Given to the fact that the network was shaky from time to time which doesn’t help if you are showing a way of deploying live into an amazon cloud there were no deficiencies.

Attending the Cakefest raised – among other things – the awareness of the importance of giving things back to the community. Further the importance of various development aspects were raised. Among them:

• Git is THE THING if you want proper version control – forget about SVN
• Think before you implement (this one should be obvious) – how you implement thing in the CakePHP way. Chose carefully which path you take: Component, Helper, Datasource…
• Datasources in general are entities where CRUD statements can be carried out. (Twitter is a datasource by this defintion)
• Implement and use testing as standard practice (implement your Tests directly after implementing any functionality)
• Continuous integration is a great thing (Tools: Phing, Xinc)
• Check out the CakePHP Media Plugin (this will resolve a lot of problems handling file- and mediauploads) and give feedback to David via GitHub
• Internationalisation is convenient with CakePHP – get sample code and slides here

Thanks for the great organisation of the event, I imagine this was no easy task to accomplish!  I am looking forward meeting you all at the next Cakefest in 2010!

Luckily this problem is already known and a Workaround to fix this problem exists.

Open up a terminal and type the following:

sudo invoke-rc.d system-tools-backends stop

sudo dpkg –configure -a

This resolved the error for me – thanks to Islevegan for his post on launchpad

The Upgrade ran without problems, but after restarting my system – a black screen was greeting me. A bit of research using Links showed me that I am not the only one running into problems after the upgrade.

After tinkering around and wasting almost a whole night I managed to have KDM, X and my Desktop running again.

If you are running into similar problems – Kubuntu Ugrade to 8.10 – X Server doesn’t start – KDM not default Display Manager, please have a read of my post to the Ubuntu Forums where I summarized my efforts getting my X-Server and Desktop back.

Not such a pleasant start – but I am looking forward
