A variable is considered dependent if it depends on an independent variable. Dependent variables are studied under the supposition or demand that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question.[a]

Are protected members/fields really that bad? No. They are way, way worse. As soon as a member is more accessible than private, you are making guarantees to other classes about how that member will behave. Since a field is totally uncontrolled, putting it "out in the wild" opens your class and classes that inherit from or interact with your class to higher bug risk. There is no way to know when a field changes, no way to control who or what changes it. If now, or at some point in the future, any of your code ever depends on a field some certain value, you now have to add validity checks and fallback logic in case it's not the expected value - every place you use it. That's a huge amount of wasted effort when you could've just made it a damn property instead ;) The best way to share information with deriving classes is the read-only property: protected object MyProperty { get; } If you absolutely have to make it read/write, don't. If you really, really have to make it read-write, rethink your design. If you still need it to be read-write, apologize to your colleagues and don't do it again :) A lot of developers believe - and will tell you - that this is overly strict. And it's true that you can get by just fine without being this strict. But taking this approach will help you go from just getting by to remarkably robust software. You'll spend far less time fixing bugs.

Public and/or protected fields are bad because they can be manipulated from outside the declaring class without validation; thus they can be said to break the encapsulation principle of object oriented programming.

Using a property or a method to access the field enables you to maintain encapsulation, and fulfill the contract of the declaring class.

Exposing properties gives you a way to hide the implementation. It also allows you to change the implementation without changing the code that uses it (e.g. if you decide to change the way data are stored in the class)

hedgeDoc := HedgeDoc new url: 'https://docutopia.sustrato.red/accesibilidad:23K?both# '; retrieveContents.

Remember there are two kinds of variable. Internal Variables and Environment Variables. PATH should be an environment variable.

All shells should tell you that your path is the same thing with BOTH of the two commands: # The PATH variable echo "$PATH" # The PATH environment variable env | /bin/grep PATH

But what if we’ve more elements to ignore? people = { "Alice" => ["green", 34, "alice@example.com"], "Bob" => ["brown", 27, "bob@example.com"] } No problem. Just re-use the underscore: people.map { |name, (_, _, email)| [name, email] } You can’t do it with any variable, though, at least in Ruby 1.9. It only works with variables that are called _: people.map { |name, (x, x, email)| [name, email] } # SyntaxError: (eval):2: duplicated argument name

We also need at least something in our CSS that can be set from outside. CSS custom properties are a great fit for this!

Since the significance of the number of functions varies with the number of all other functions (i.e., the size of the employed labor force), it should be ex- pressed as a ratio to the latter. Hence the lower the ratio of managers, proprietors, and officials7 to the employed labor force the greater is the concentration of power. (This measure will hereafter be called the MPO ratio.

With JavaScript, you can actually calculate the width of the scrollbar and whether it’s visible by comparing two properties—window.innerWidth and document.body.clientWidth. If these are equal, the scrollbar isn’t visible. If these are different, we can subtract the body width from the window width to get the width of the scrollbar:const scrollbarWidth = window.innerWidth - document.body.clientWidthWe’ll want to perform this both on page load and on resize, in case someone resizes the window vertically and changes the overflow. Then, once we have the scrollbar width, we can assign it as a CSS variable:document.body.setProperty("--scrollbarWidth", `${scrollbarWidth}px`)

We need to pick a name for that value to be remembered and we can use that symbolic name to retrieve the value later

Here’s a CSS variable (formally called a “CSS custom property“)

A great thing about CSS variables is their reactive nature. As soon as we update them, whatever property has the value of the CSS variable gets updated as well.

The standard cascade rules also apply to the CSS Variables.So, if a custom property is declared multiple times, the lowermost definition in the css file overwrites the ones above it.

Understanding types of variables

You can style a component by overriding the available CSS variables.

style.css now uses native CSS variables

Some GitLab features can behave differently for each environment. For example, you can create a secret variable to be injected only into a production environment.

Testing and Confinement - source that utilizes globals is somewhat more difficult to test because one cannot readily set up a 'clean' environment between runs. More generally, source that utilizes global services of any sort (e.g. reading and writing files or databases) that aren't explicitly provided to that source is difficult to test for the same reason. For communicating systems, the ability to test system invariants may require running more than one 'copy' of a system simultaneously, which is greatly hindered by any use of shared services - including global memory - that are not provided for sharing as part of the test.
