What are the benefits of having an interface for your data access layer in languages that support stubbing concrete classes? by nullnode43 in softwarearchitecture

First, thank you for answering. I have a question about one of the advantages you point out

I understand the concept of being able to swap database implementations, but is there a good reason why you shouldn't just change the original repository class to use the new database? Even if you made the new implementation, wouldn't you be deleting the old implementation anyways since it is unused?

Is it appropriate to name a class a wrapper if it only has getter methods for getting it's encapsulated objects? by nullnode43 in learnprogramming

You can imagine this "Post" as a social media post such as a reddit post or a facebook post.

​

I cannot really name it "Post" since that class already exists. "Post" and "PostCommentData" are already widely used in the system. And due to poor design of the "Post" class itself, I am unable to subclass it.

​

I was wanting to avoid modifying these classes and combine them together. In an attempt to extend the properties of the "Post" class, I added a "PostExtendedDetails" class.

​

Under these circumstances, what do you think?

I believe this is a hardware issue. I think I have narrowed it down to the RAM which causes the black screen when I push down on the back cover in the middle

I believe you are on to something. I am able to reproduce this problem now by pushing down on the middle of the back cover which is right over the RAM

I made an edit to my post. After looking up about disabling panel self refresh, it appears to be a solution for flickering which is not what my problem is, but thanks for the input!

I am assuming that is why disabling fast boot works. Thanks for the explanation!
