The Performance of Arrays - Chris Burrows - 2 views

Development .Net Arrays Covariant Performance Reference

shared by Joel Bennett on 20 Jul 10 - Cached
  • arrays of reference types are covariant in their element type, but not safely
  • where did that exception come from? It came from the runtime, which was in a unique position to know what the real type of the array object was, and the real type of the element. It needed to determine if the assignment was allowable and throw if not. Now if you think about this for a minute, you can see that it’s going to have to perform that check for every assignment to an array element
  • arrays are covariant only for reference types?
  • ...3 more annotations...
  • So if I want to have an array of reference types, but get the runtime to treat it like an array of value types, what have I got to do? Just wrap the reference type in a value type
  • So I got rid of that check, right? But I added the initialization of a value type. Did I win or lose? Let’s do some timing to figure it out.
  • when I build Debug binaries, the Reference<T> trick makes my example about three times SLOWER.

    Arrays are covariant only for reference types. If you use a struct wrapper to turn a reference type into a value type, the initialization of the value type takes less time than array assignment.

Fabulous Adventures In Coding : The Stack Is An Implementation Detail, Part One - 0 views

blogs.msdn.com/...-an-implementation-detail.aspx

clr cli .NETGeneral c# memory allocation

shared by Matteo Spreafico on 14 Aug 09 - Cached
  • Almost every article I see that describes the difference between value types and reference types explains in (frequently incorrect) detail about what “the stack” is and how the major difference between value types and reference types is that value types go on the stack.
  • I find this characterization of a value type based on its implementation details rather than its observable characteristics to be both confusing and unfortunate. Surely the most relevant fact about value types is not the implementation detail of how they are allocated, but rather the by-design semantic meaning of “value type”, namely that they are always copied “by value”.
  • Of course, the simplistic statement I described is not even true. As the MSDN documentation correctly notes, value types are allocated on the stack sometimes. For example, the memory for an integer field in a class type is part of the class instance’s memory, which is allocated on the heap.
  • ...3 more annotations...
  • As long as the implementation maintains the semantics guaranteed by the specification, it can choose any strategy it likes for generating efficient code
  • That Windows typically does so, and that this one-meg array is an efficient place to store small amounts of short-lived data is great, but it’s not a requirement that an operating system provide such a structure, or that the jitter use it. The jitter could choose to put every local “on the heap” and live with the performance cost of doing so, as long as the value type semantics were maintained
  • I would only be making that choice if profiling data showed that there was a large, real-world-customer-impacting performance problem directly mitigated by using value types. Absent such data, I’d always make the choice of value type vs reference type based on whether the type is semantically representing a value or semantically a reference to something.

    There's a plethora of new HTML5 form input types (13 new ones to be exact) that make creating engaging and easy-to-use web forms much easier for web designers. The new HTML5 input types give us data validation, date picker controls, color picker controls, inline help text, and more in the web browsers that support them. Advantage of HTML5 Form Input Types The benefits of these new input types are tremendous for web designers. First, the new input types reduce our reliance on client-side- and server-side-scripting for validating common data types like dates, email addresses, and URLs. For mobile UI developers: You know that creating cross-platform web forms using HTML4 standards is a pain. Using HTML5 form input types could make things easier. For instance, a form written with HTML5 can utilize the mobile device's native specialized keyboards depending on what the target input type is. Here's an example of using HTML4 input types (on the left) for entering dates in a web form versus using the HTML5 date input type (on the right):

Values, Types, and Operators :: Eloquent JavaScript - 0 views

eloquentjavascript.net/01_values.html

javascript programming

shared by fspore on 27 Jun 15 - No Cached
  • Not all operators are symbols. Some are written as words. One example is the typeof operator, which produces a string value naming the type of the value you give it.
  • Having such numbers is useful for storing strings inside a computer because it makes it possible to represent them as a sequence of numbers. When comparing strings, JavaScript goes over them from left to right, comparing the numeric codes of the characters one by one.
  • There is only one value in JavaScript that is not equal to itself, and that is NaN, which stands for “not a number”.
  • ...16 more annotations...
  • In practice, you can usually get by with knowing that of the operators we have seen so far, || has the lowest precedence, then comes &&, then the comparison operators (>, ==, and so on), and then the rest. This order has been chosen such that, in typical expressions like the following one, as few parentheses as possible are necessary:
  • The difference in meaning between undefined and null is an accident of JavaScript’s design, and it doesn’t matter most of the time. In the cases where you actually have to concern yourself with these values, I recommend treating them as interchangeable (more on that in a moment).
  • . Yet in the third expression, + tries string concatenation before numeric addition
  • When something that doesn’t map to a number in an obvious way (such as "five" or undefined) is converted to a number, the value NaN is produced.
  • Further arithmetic operations on NaN keep producing NaN, so if you find yourself getting one of those in an unexpected place, look for accidental type conversions.
  • g ==, the outcome is easy to predict: you should get true when both values are the same, except in the case of NaN.
  • But when the types differ, JavaScript uses a complicated and confusing set of rules to determine what to do. In most cases, it just tries to convert one of the values to the other value’s type. However, when null or undefined occurs on either side of the operator, it produces true only if both sides are one of null or undefined.
  • That last piece of behavior is often useful. When you want to test whether a value has a real value instead of null or undefined, you can simply compare it to null with the == (or !=) operator.
  • The rules for converting strings and numbers to Boolean values state that 0, NaN, and the empty string ("") count as false, while all the other values count as true.
  • where you do not want any automatic type conversions to happen, there are two extra operators: === and !==. The first tests whether a value is precisely equal to the other, and the second tests whether it is not precisely equal. So "" === false is false as expected.
  • The logical operators && and || handle values of different types in a peculiar way. They will convert the value on their left side to Boolean type in order to decide what to do, but depending on the operator and the result of that conversion, they return either the original left-hand value or the right-hand value.
  • The || operator, for example, will return the value to its left when that can be converted to true and will return the value on its right otherwise. This conversion works as you’d expect for Boolean values and should do something analogous for values of other types.
  • This functionality allows the || operator to be used as a way to fall back on a default value. If you give it an expression that might produce an empty value on the left, the value on the right will be used as a replacement in that case.
  • The && operator works similarly, but the other way around. When the value to its left is something that converts to false, it returns that value, and otherwise it returns the value on its right.
  • Another important property of these two operators is that the expression to their right is evaluated only when necessary. In the case of true || X, no matter what X is—even if it’s an expression that does something terrible—the result will be true, and X is never evaluated. The same goes for false && X, which is false and will ignore X. This is called short-circuit evaluation.

  • Definition: A traits template is a template class, possibly explicitly specialized, that provides a uniform symbolic interface over a coherent set of design choices that vary from one type to another.
  • An important use of traits is as "interface glue"—universal non-intrusive adapters. If various classes implement a given concept in slightly different ways, traits can fit those implementations to a common interface.
  • Definition: A traits class (as opposed to a traits template) is either an instantiation of a traits template, or a separate class that exposes the same interface as a traits template instantiation.
