How to run a function in ruby


How to run a function in ruby



So, this is already making me feel stupid, but I need the answer. I think I learnt it somewhere but I haven't used ruby in a while so I probably forgot.
I am trying to set an age inside of a function in ruby and then get the age displayed.


def set_age(new_age)
@age = new_age
end

def get_age
@age
end



But how do I get this code to run?

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss.

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...

iOS Top Alignment constraint based on screen (superview) height Let's say for example i want my view's top margin be 30 px for iPhone 6s and for the other screen i want to change this constants from 30 to X where X is proportional to total height of screen i.e. 36.5 for iPhone X, 33 for iPhone 6s plus, 25 for iPhone SE And so on .... I know i can take @IBOutlet of NSLayoutConstraint and change it programmatically but what i want is i want to set it like aspect ratio that we have for height width like subview's heigh width is proportional it's superview it changes with super view's height and width @IBOutlet NSLayoutConstraint 2 Answers 2 The constraint you need here is the superView's centerY set multiplier to 0.5 if you want the top anchor's constant to be 0.25 of screen height from the top , so adjust the multiplier according to this logic which is height_of_scre...
