When calculating an eigenvector you may change its sign and the solution will also be a valid one.

So any PCA axis can be reversed and the solution will be valid.

Nevertheless, you may wish to impose a positive correlation of a PCA axis with one of the original variables in the dataset, inverting the axis if needed.

A pattern p implies a type T if the pattern matches only values of the type T.

The rare cases in which monkey-patching has to be used as a last resort tend to be cases where you don't have access to the source code to implement a proper solution, or where you're somehow unable to define a subclass of the class you're hoping to fix or extend.

It's a bad practice in most other cases and often a final resort in a codebase that has become burdened with too many bad design decisions, when it's not trying to fix a third party solution for which you don't have the code.

• Assumes your dates are in Column A of your worksheet.
• Can be used to replace the CreateSubsetWorkbook sub you have.

You can still use the PromptUserForInputDates and then call this sub instead of CreateSubsetWorkbook.

The problem is with the scanner class. Because when you use call z=sc.nextLine(); this call first take the input from the line where you enter the number to push into the stack because int p=sc.nextInt(); this line only take one integer but does not finish the whole line.

So you can manually finish the line by adding a sc.nextLine() before taking the input for yes or no. By adding the extra nextLine() will finish the current line when you inter the integer.

Your image size is 2x2 and the image format is RGB. Therefore the length of a line is 6 bytes. By default OpenGL assumes that the start of each row of an image is aligned to 4 bytes.

This is because the GL_UNPACK_ALIGNMENT parameter by default is 4. Since the image has 3 color channels (GL_RGB), and is tightly packed the size of a row of the image may not be aligned to 4 bytes.
When a RGB image with 3 color channels is loaded to a texture object and 3*width is not divisible by 4, GL_UNPACK_ALIGNMENT has to be set to 1, before specifying the texture image with glTexImage2D:

This is called Template Method pattern.

This pattern allows children class to implement only the relevant bit of logic without the knowledge that is encapsulated in the parent class.

In your words, it allows every specific pizza store to define some characteristics of a pizza without knowing how the pizza must be prepared, baked, cutted, boxed.

Apache Arrow utilizes a pretty similar idea of Java off-heap storage as Apache Ignite does. For Apache Arrow it means that objects like IntVector don't actually store data in their on-heap layout. They just store a reference to a buffer containing an off-heap address of a physical representation. Technically it's a long offset pointing to a chunk of memory within JVM address space.

When you restart your JVM, address space changes. But in your Apache Ignite native persistence there's a record holding an old pointer. It leads to a SIGSEGV because it's not in the JVM address anymore (in fact it doesn't even exist after a restart).

You could use Apache Arrow serialization machinery to store data permanently in Apache Ignite or even somewhere else. But in fact after that you're going to lose Apache Arrow preciousness as a fast in-memory columnar store. It was initially designed to share off-heap data across multiple data-processing solutions.

Therefore I believe that technically it could be possible to leverage Apache Ignite binary storage format. In that case a custom BinarySerializer should be implemented. After that it would be possible to use it with the Apache Arrow vector classes.
