the := operator is a shortcut for declaring and initializing a variable in one line (Go uses the value on the right to determine the variable's type). Taking the long way, you might have written this as: var message string message = fmt.Sprintf("Hi, %v. Welcome!", name)

You can close the single quotes before starting the double quotes and do the reverse at the end of that inner section to achieve what you want:

To manage a variable-size stack frame, x86-64 code uses register %rbp to serveas a frame pointer

At times, however, local data mustbe stored in memory. Common cases of this include these:.There are not enough registers to hold all of the local data..The address operator ‘&’ is applied to a local variable, and hence we must beable to generate an address for it..Some of the local variables are arrays or structures and hence must be accessedby array or structure references.

We cannot make the above statement reactive because we touch tmpCopyAsTemplates.

It works if you always want b to be the value deriving from a. However in the example above, we want the value of b to be temporarily out of sync of a.

My mental model has always been that a reactive declaration like $: b = a * 2 defines b in it's entirety ("Here's my recipe for b and all the ingredients, please Svelte make b always up to date"). And outside of this declaration b is immutable.

For me there is a distinct difference between these two scripts: let a = 1; $: b = a * 2; let a = 1; let b; $: { b = a * 2 }; The first example defines a "recipe" for how to create b and b is completely defined by that declaration. Outside of that it is immutable, data flows only into a single sink. The second example declares a variable b and then uses a reactive statement to update it. But it also allows you to do with b whatever you want. If someone wants to go that route (definitely not me), they are free to do so at their own risk of ensuring consistency.

First of all, here is what I meant by updating reactive declared variable

The intention of the issue #2444 was to propagate the changes of the reactive declared variables back to its dependencies. in the context of this example, would meant, updating b should update a as well.

The intended behavior for the code snippet above is to reactively update b when a changes allows b temporarily go "out-of-sync" of a when calling update, setting b to 42 in this case, b is not always a * 2 however, if a changes again, b will be updated back to a * 2, instead of staying at 42

You declare a reactive variable and it's dependencies ("recipe").

I don't think these are two different interests in contrast with each other. I wanna update that temporary object and when the dep changes I re-create the temporary object. Simple as that.

local variables such as x are often kept in registers rather thanstored in memory locations. Register access is much faster than memory access.

I've seen (and fixed) Ruby code that needed to be refactored for the client objects to use the accessor rather than the underlying mechanism, even though instance variables aren't directly visible. The underlying mechanism isn't always an instance variable - it can be delegations to or manipulations of a class you're hiding behind a facade, or a session store with a particular format, or all kinds. And it can change. 'Self-encapsulation' can help if you need to swap a technology, a library, an object specification, etc.

a principle I use is: If you have an accessor, use the accessor rather than the raw variable or mechanism it's hiding. The raw variable is the implementation, the accessor is the interface. Should I ignore the interface because I'm internal to the instance? I wouldn't if it was an attr_accessor.

I have been wrapping instance variables in accessor methods whenever I can though.

Also, Sandi Metz mentions this in POODR. As I recall, she also advocates wrapping bare instance variables in methods, even when they're only used internally. It helps avoid mad refactoring later.

Local variables can even be declared with the same name as a global variable. If this happens, there are actually two different variables with the same name: one local and one global. This helps ensure that an author writing a local variable doesn’t accidentally change the value of a global variable they aren’t even aware of.

The GROUPS subcommand specifies an unknown variable or a long string variable.

Paths are traversed in the order they occur in the search path. By default, this means the files in app/assets take precedence, and will mask corresponding paths in lib and vendor.

Understanding types of variables

Otherwise, please take the time to read about declarations hoisting (MDN, Adequately Good) and variable shadowing, as these concepts are key to fully understanding TDZ.

Feature predictive power will be calculated for all features contained in a dataset along with the outcome feature. Works for binary classification, multi-class classification and regression problems. Can also be used when exploring a feature of interest to determine correlations of independent features with the outcome feature. When the outcome feature is continuous of nature or is a regression problem, correlation calculations are performed. When the outcome feature is categorical of nature or is a classification problem, the Kolmogorov Smirnov distance measure is used to determine predictive power. For multi-class classification outcomes, a one vs all approach is taken which is then averaged to arrive at the mean KS distance measure. The predictive power is sensitive towards the manner in which the data has been prepared and will differ should the manner in which the data has been prepared changes.

Mutual information is one of many quantities that measures how much one random variables tells us about another. It is a dimensionless quantity with (generally) units of bits, and can be thought of as the reduction in uncertainty about one random variable given knowledge of another. High mutual information indicates a large reduction in uncertainty; low mutual information indicates a small reduction; and zero mutual information between two random variables means the variables are independent.
