De Free Technology Academy geeft vanaf januari mastercursussen over vrije software. Het is een initiatief van onder meer de Open Universiteit Nederland. Al het cursusmateriaal is vrij toegankelijk.

Er wordt gestart wordt met 2 modules:

• The concepts of Free Software and Open Standards
• The GNU/Linux Operating System

Hogeschool NOVI start in januari met een alternatief voor Information Technology Infrastructure Library (ITIL)-trainingen. De hbo-studie IT Service Management (ITSM ) richt zich naast ITIL versie 3 op andere denkwijzen over beheer, waaronder ISO 2000, BiSL en ASL. Volgens de hogeschool is de studie nodig omdat ITIL met versie 3 een complexe weg inslaat die wat betreft certificering veel kosten met zich meebrengt. Bovendien is de waarde van de ITIL-certificaten buiten de ict vrijwel nihil.

Fontys Hogeschool Techniek en Management en aanbieders van Linux-trainingen beginnen samen een Nederlandse versie van Het Linux Professional Institute (LPI). Dienstverleners als Ictivity, StarTel en AT Computing doen mee aan het initiatief.

Three tutorials that demonstrate the capabilities of Oracle Service Bus, in particular the functionality that isn't included in Oracle ESB:

• Exposing a simple service: getting to know OSB basics such as Business and Proxy Services, and simple routing rules and transformation capabilities based on XQuery.
• New adapters: getting to know the adapter support in OSB such as the e-mail adapter.
• Data enrichment: more advanced routing and transformation capabilities of OSB.
  

Web creators might aim for beautiful, accessible, usable interfaces to house their smart, web-native content, but they don’t often have learners’ goals or needs in mind—if they even know what those needs are. Learners require more from us than keywords and killer headlines. They need an environment that is narrative, interactive, and discoverable.

In this presentation, based on real-life cases from the financial industry, Michael Poulin shows how to use 7 service oriented principles, Composability, Autonomy, Contracts, Abstraction, Loose Coupling, Reusability, and Discoverability, to handle service behavior in the execution context and UI changes, and how to prepare for unexpected changes.

Een tip uit deze post:

Make sure when testing with a software load balancer that it uses HTTP cookie affinity rather than IP address affinity.

This is bad when testing because it means that if you run a test script from a single machine it will only target a single machine in the cluster.

Aanbieder van ict-cursussen Compu'train gaat verhuizen. De opleider heeft een nieuw pand gekocht in Utrecht. Doordat de ruimte efficiënter kan worden ingedeeld, is in het nieuwe kantoor meer lesruimte op minder oppervlakte. Compu'train verhuist maandag 2 november naar het nieuwe pand.

Service orientation is a paradigm that frames what you do. Service-oriented architecture (SOA) is a type of architecture that results from applying service orientation. We have been applying service orientation to help organizations consistently deliver sustainable business value, with increased agility and cost effectiveness, in line with changing business needs.
