I am 72 and I have adopted 2 kittens this year. I am concerned about my age. Will they miss me too much if I die?

I have no doubt that your cats would miss you. Pets become really attached to their human families. If you were to leave them, they would mourn you.

However, you've already done the first thing you can do to make it easier for them: you've adopted two kittens. They have a bond with you, but they also have a bond with each other. I imagine you have considered arrangements for their care in case anything happens to you, like a hospital stay or protracted illness. I would also take steps to see that, in the event they must be rehomed, that they are allowed to remain together, at least for the initial adjustment period. In our church, when a person with pets passes away, congregation members do make an effort to make it as easy for their furbabies as possible.

You can do a few things to make your cats more attractive to potential adopters, like making sure they are spayed or neutered, have regular visits to the vet, eat healthy food, and are thoroughly housetrained. Keep a file on them in with your other important papers that records their names, date of birth (or approximate

Can you become a doctor if you are afraid of vomit? I have emetophobia.

I have emetophobia, and I’m a medical student.

It really depends on a few things:

  • Severity: Of course, if you have an extremely severe case of emetophobia, where you think about the topic for hours every day, I wouldn’t recommend becoming a doctor. If you were walking around a ward and all you could think about was ‘someone might vomit on me’ then unfortunately being a doctor is a pipe dream. My case of emetophobia is mild fortunately
  • Nature: Emetophobia can be a fear of someone else vomiting on you; a fear of yourself becoming nauseated and vomiting; a fear of vomiting via a certain method i.e. being drunk or catching norovirus. If you only fear vomiting yourself, then you could consider becoming a doctor. I myself only fear vomiting by catching norovirus: this could be a problem if someone came into hospital with norovirus. I would worry, but because my case is mild I would be able to get on with it
  • Reaction: Your reaction to, for example, someone vomiting a few meters away

In computer vision, is JPEG compression intrinsically better than a bitmap?

No, no and no.

First, no one ever uses compressed JPEGs directly in computer vision. It has to be uncompressed into RGB first. There’s no performance advantage.

Second, what JPEG considers nonessential and what computer vision considers nonessential are usually two very different things. Among other reasons, JPEG compression can be badly disruptive for CV purposes because you get blocking artifacts (apparent edges appearing where none were in the original image) and that can wreak havoc on motion tracking.

This also extends to MPEG-family compression methods. You usually don’t have a choice in the matter because you rarely have the luxury of feeding raw/uncompressed data straight from the camera into the CV library, or storing it in a lossless form, so you just have to hope that it’s compressed as lightly as possible, with an understanding that you end up with a degree of noise introduced during compression.

All else equal, wavelet-based formats such as JPEG2000 would be better because at least you don’t get blocking.

How does explain the concept of OOP in C++ language ? How do they work?

I cannot put a whole wiki here !

However , here is the gist :

Object consist of state aka attributes and behaviour aka interface.

They generally model the real world object , but they can be represent intangible stuff.

Real world objects like student , rectangle etc.

Intangible objects like set , list , DatabaseConnection etc

Attributes are represented by variables (simple or compound).

While behaviour is represented by methods or functions.

For ex:

Consider a rectangle object which has state (length and width) and behaviour may include getting toknow area , perimeter .

Responsible for itself:

The idea is that an object is responsible for itself.Imagine it like a person which you can communicate and interact with it , just like we do it it real world.

Class based language:

C++ is class based language . It means you have to create a class first and then create objects from it. There are also object based languages like Javascript , in which there is no need to create a class , you can directly create a object .

So whats a class ?

It basically a template that dictates what are the attributes and behaviour of the object.

Here is a example:

  • Human is class.
  • You and me
    • are objects created from Human class
    • have states
    • are same but still are different because we have different state
      • as we have different sex and some other attributes like height , weight etc

So human is a class , you and me are objects created from it.

OOP vs procedural:

The data being manipulated is wrapped or encapsulated within the object and only the privileged methods can access it.

In procedural methods have direct access to the data as they are globals.

So debugging gets little easy with OOP as you know that only the certain methods can modify it.

Other concepts include:

  • Inheritance
  • Polymorphism
  • Composition
  • Encapsulation

You better read some books about it:

One I think useful is :

  • Object Oriented Thought Process (Addison Wesley)

First understand the OOP concepts and look for implementation in languages !

Is the Elder Scrolls Online still a monthly payment system?

No, Elder Scrolls Online is not, and never was a monthly payment system. You pay for the game once, then you play.

They do have in-game purchases if you want extra’s (pets, houses, costumes, fancy horses, etc). This is completely optional. These in-game purchases are not required to play the game, or to have fun. They are simply “cute” little items to make your character more unique.

I have played ESO for about 10 months, and I've never spent a dime on in-game purchases. I like the game “as is”.
