Symbian OS is an open operating system used primarily in smartphones. It is microkernel-based, uses C++ as its primary programming language, and has a modular architecture. Key components include the UI framework, application services, generic OS services, base services, and a kernel. Major versions include 9.0 through 9.5, which added features like improved security, location services, and multimedia support. Licensing originally involved signing applications, but Symbian is planned to become fully open source in 2009. Symbian powers a variety of smartphones across different manufacturer interfaces and has over 60% of the smart mobile device market share.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

15. License.. Symbian is not open source software yet. Phone manufacturers and other partners are provided with parts of its source code. The APIs are publicly documented and up to Symbian 8.1 anyone could develop software for Symbian OS. Symbian9.1 introduced capabilities and Platform Security framework. To access certain capabilities, the developer has to digitally sign their application. Have to sign via the Symbian Signed program; which uses independent Test Houses and/or phone manufacturer approval. In 2008 Nokia has stated that Symbian OS (including the platforms S60, UIQ and MOAP(S)) will become open source in the first half of 2009.
16. Application Programming Languages.. The native language of the Symbian OS is C++, although it is not a standard implementation. Other languages which can be used are, OPL – Open Programming Language is an embedded programming language found on e.g. the Nokia 9200, 9300 and 9500 Communicator series mobile telephone/PDA Python Visual Basic Simkin Perl together with the Java ME and PersonalJava flavours of Java.
