Everything must come to an end

I finally got my new laptop after having a loaner for over a month so I can now resume blogging (at least more easily).  I’ve been excited about all of the new features and functionality of Essbase 11.1.2.4 and there has bee a flurry of blogs that have described that functionality. Today, Tim Tow posted one feature going away the VB API.   There are a number of other features that you might not be aware of as either completely gone or depreciated so they won’t be supported in the future.

Essbase VB API is Officially Dead

It is with a sad heart that bring you the news that, as of Essbase 11.1.2.4, the Essbase VB API is officially dead.  I cut my teeth in Essbase working with that API way back in the mid-1990's, but the writing had been on the wall for some time.  Microsoft stopped supporting VB years ago, so it was only a matter of time before this time would come.  That being said, I haven't used the VB API for any new Essbase work since about 2001; the Essbase Java API is alive and growing so my efforts have been there.

Here is the official notification:

5 Minute JavaScript #5 Globally Implied

JavaScript uses the var-statement to declare variables and bind them to a scope. But this statement isn’t mandatory. In JavaScript you are allowed to define a value without this statement. When you do not use the var-statement, the variable will be added to the Global Object (see previous post).

Binary search - is it still most optimal?

If you have a sorted collection of elements, how would you find index of specific value? "Binary search" is likely to be your answer. Algorithms theory is teaching us what binary search is most optimal algorithm for this task with log(N) complexity. Well, hash table can do better, if you need to find key by exact match. In many cases, though, you have reasons to have your collection sorted, not hashed.

Subscriptions

One of the most tiresome things to do when managing multiple applications is to keep things like templates, and security up-to-date across all applications.
