An airhacks.fm conversation with Michael Bolz (@onemibo ) about:
The first line of Turbo Pascal in 1992, 286 Compaq with a Turbo button, writing an installer for friends, C64 vs. PC,
Jump and Run without jumping, writing some HTML code with DreamWeaver, What You See is NOT what you get, studying at the University of Applied Sciences in Karlsruhe,
building web based applications with Struts, Java is easier to learn than C/C++, starting with "public static void main",
then managing students with Java, writing UI tools in Swing / AWT for applying patches in CMS, JSF vs. Struts, the steinbeis foundation
system migration from EJB 2.1 to EJB 3.1 in 2008, EJB 2.1 required code generation with xdoclet - and EJB 3.1 was nice, Heidelberg is nicer than Karlsruhe,
the JAX 2012 meeting with JMS expert Ruediger zu Dohna, simplifications with JMS 2.X, copying museum code from the internet, copy and paste oriented programming, working for SAP, opensource at SAP,
starting Apache Olingo, the ODATA specification for accessing backends, backend for frontends, ODATA is queryable database,
ODATA exposes CRUD+ operations as standardised REST interface, Olingo is ODATA implementation for Java, Olingo is a raccoon, Olingo team started with 4 developers,
ODATA v4 is an OASIS standard, ODATA v4 is mostly based on JSON, 2 developers are currently maintaining Olingo, JPA extension only exists for the Olingo v2 and not v4,
most SAP services are available as ODATA endpoints, SAP's UI5 components can be also bound to ODATA, SAP UI5 widgets are also available as SAP ui5 WebComponents,
MaxDB, teaching ABAP developers Java, nightly conversations about the R3 VM,
in ThinWARs there is nothing to scan,
removing unwanted dependencies is a good idea, Vulnerability Assessment Tool (Vulas) by SAP research,
Vulas is going to be donated to Eclipse Foundation, Vulas scans transitive dependencies as well as the source code of the dependencies,
SAP runs a lot of Java apps internally, Olingo comprises two parts - the metadata and the execution part,
Olingo v2 comes with JPA extension and a Servlet as entry point, Microsoft contributed the Olingo client, Java Annotation extension for Apache Olingo V2,
Olingo is open for contributions, it is a good idea to discuss new features on the mailing list first, new Olingo features must be backward compatible,
