It is important to select the right API endpoint of SAP Cloud Foundry to deploy your applications on SAP Cloud Platform. In this blog, I’ll describe exactly how to do that. Logon to your SAP Cloud Foundry trial account by
How to change Jupyter notebook start up folder in Anaconda
In this post I’ll discuss how to change the Jupyter notebook startup folder in Anaconda which is installed on a Windows system. I find it easier to work in a startup folder where I keep all my development workspaces. So
What is Pooled Variance and how is it calculated
Definition Pooled Variance is a method to estimate the common variance of two or more populations (the underlying assumption here is that the variance of these populations is the same) by using the sample variances from these populations. Formula Pooled
Variance and Standard Error of the Mean – Derivation
Prerequisite concepts Expectation is the probability-weighted mean of the sum of all the possible outcomes of an experiment. It is also known as the expected value, mathematical expectation, EV, average, mean value, mean, or first moment. It is denoted as
How to check if an enum contains a given string
While programming in Java, there is a frequent requirement to check if an Enum contains a given String value. There are multiple ways to validate this. But I find the EnumUtils class of Apache Commons Lang the most convenient to
How to show line numbers in Eclipse
Although it is seems simple but I’ve seen people struggle with this. Therefore, I decided to put a real quick post on how to show line numbers in Eclipse editor. There are two ways to enable line numbers in Eclipse.
How to set maximum line length in eclipse
To set the maximum line length in Eclipse, open Eclipse and in the menu bar, go to Window -> Preferences and in the pop-up window, go to Java -> Code Style -> Formatter. This will open up the Formatter options
How to translate between coordinate systems that use different basis vectors
In my previous blogs I talked about Linear Transformations and how can we find the transformation matrix of a linear transformation. In this blog we will try to understand how to translate basis vectors between different coordinate systems with the
What is the significance of matrix multiplication
It is important to always think of a matrix as a representation of the transformed standard basis vectors rather than just thinking about a matrix as a rectangular array of random real numbers. With this thought, matrix multiplication can be
How to find the transformation matrix of a linear transformation
The transformation matrix is a representation of the transformed standard basis vectors. For example, in a 2-dimensional coordinate system if the transformed coordinates of the unit vector are, and that of unit vector are, These two basis vectors can be
