In the Optimizely CMS world, we see GUIDs everywhere. They are unique identifiers for content types and more. As part of Optimizely CMS development, developers are advised to always specify GUIDs in their Content-Type declarations. If one isn’t specified, the DB assigns one dynamically when saving the Content-type. A big reason for this is that […]

I had a bug in a TM1 application recently that was very difficult to track down, and it was because I didn’t understand the different ways that TM1 might respond to vague or incorrect MDX expressions.  MDX makes some unexpected assumptions.

I have heard many people say, “I’ll just download a screen reader and test that bug”. Using a screen reader takes time and practice to use in a similar way that a user with a disability would use the tool. It’s important to know the keyboard shortcuts as well as understanding how to use them […]

Completable-Future is used for asynchronous programming in Java. Asynchronous programming means writing non-blocking code by running a task on a separate thread than the main application thread and notifying the main thread about its progress, completion or failure. This way, main thread does not block/wait for the completion of the task and it can execute other tasks […]

If you are upgrading to Optimizely CMS 12, one of the breaking changes to consider is the change to the Dependency Injection(DI) framework. Earlier versions of Optimizely CMS had their own DI hosting framework that supported other concrete DI implementations, like StructureMap. With CMS 12 and ASP.Net Core, DI framework is built into the system. […]

Customization is Crucial One of the essential customization concepts in Sitecore is the ability to customize the flow of the application globally without having to add a rendering to every page or include code in a universal layout.
