What is Symbian Signing?

Symbian signed is, its application signing program that promotes best practice in Symbian OS content and application development. The program tests applications against industry-agreed criteria in support of network operator and mobile manufacturer requirements.

Symbian Signed offers three signing options to support the different needs of Symbian OS, these options are

Test House Certification: Suitable for ISVs with a small number of applications. Applications are submitted to the Symbian Signed portal and tested by an independent third party test house.
Self-Certification: Suitable for ISVs with more than 15 of their own applications that require Symbian Signed status. ISVs or network operators certify their own applications through the re-use of internal, recognized quality assurance processes.
Publisher Certification: Suitable for application publishers, Symbian OS licensees and network operators or any public software distribution portal owner. The publisher tests and certifies the application using its own quality assurance processes on behalf of the originating ISV.

Symbian Signed typically guarantees that a signed application

• No files remains on the phone when the application is uninstalled
• The application only creates files on the drive where it has installed unless the user has explicitly given permission to write files elsewhere.
• The application can be closed thought the applications task list.
• The application detects low memory conditions and behaves correctly. Typically it should not start under particularly low memory conditions as this may compromise other key functionality of the phone.
• The application pauses when necessary, for example when there’s an incoming call.
• The application does not crash when storage memory is full.
• The application consumes too much system resources
• The application has been signed against a valid developer identity certificate.

How "Bluetooth" name is coined?

What is Bluetooth?

Bluetooth is the term used to describe the protocol of a short range (10 meter) frequency-hopping radio link between devices. These devices are then termed Bluetooth - enabled. Today Bluetooth technology has become a norm to replace cables from short range electronic appliances. Bluetooth radio modules operate in the unlicensed ISM band at 2.4GHz, and avoid interference from other signals by hopping to a new frequency after transmitting or receiving a packet.

Do you know how Bluetooth name is coined?

Bluetooth has a very interesting namesake in the person of a 10th century Danish King. Personally responsible for the unification of Denmark, Norway and Sweden, King Harald Blatland’s legendary affinity for tooth-staining blueberries gained him the nickname of Bluetooth.

Just as King Blatland successfully united different cultures centuries ago, bluetooth technology has united the realms of today’s electronic devices with resounding success. As a wireless tip of the hat to King Blatland, Bluetooth technology has embraced the runic alphabetic characters for H and B as its logo.
