Circle To create a circle, define an element with an equal width and height (a square) and then set the border-radius property of this element to 50%. HTML <div class="circle"></div> CSS .circle { width: 50px; height: 50px; background: rgb(246, 156, 85); ...

A closure can be defined with a typealias. This provides a convenient type placeholder if the same closure signature is used in multiple places. For example, common network request callbacks or user interface event handlers make great candidates for being "named" with a type alias. public...

;; disable automatic loading of packages after the init file (setq package-enable-at-startup nil) ;; instead load them explicitly (package-initialize) ;; refresh package descriptions (unless package-archive-contents (package-refresh-contents)) ;;; use-package initialization ;;; install ...

An element's opacity can be set using the opacity property. Values can be anywhere from 0.0 (transparent) to 1.0 (opaque). Example Usage <div style="opacity:0.8;"> This is a partially transparent element </div> Property ValueTransparencyopacity: 1.0;Opaqueopacity: 0....

To create a list of constants - assign iota value to each element: const ( a = iota // a = 0 b = iota // b = 1 c = iota // c = 2 ) To create a list of constants in a shortened way - assign iota value to the first element: const ( a = iota // a = 0 b // b = 1 c /...

iota can be used in expressions, so it can also be used to assign values other than simple incrementing integers starting from zero. To create constants for SI units, use this example from Effective Go: type ByteSize float64 const ( _ = iota // ignore first value by assigning to b...

The value of iota is still incremented for every entry in a constant list even if iota is not used: const ( // iota is reset to 0 a = 1 << iota // a == 1 b = 1 << iota // b == 2 c = 3 // c == 3 (iota is not used but still incremented) d = 1 << iota ...

Because iota is incremented after each ConstSpec, values within the same expression list will have the same value for iota: const ( bit0, mask0 = 1 << iota, 1<<iota - 1 // bit0 == 1, mask0 == 0 bit1, mask1 // bit1 == 2, mask1 == 1 _, _ ...

Download the Datastax PHP driver for Apache Cassandra from the Git project site, and follow the installation instructions. We will be using the "users" table from the KillrVideo app and the Datastax PHP driver. Once you have Cassandra up and running, create the following keyspace and tabl...

Changing some CSS attribute will trigger the browser to synchronously calculate the style and layout, which is a bad thing when you need to animate at 60fps. DON'T Animate with left and top trigger layout. #box { left: 0; top: 0; transition: left 0.5s, top 0.5s; position: absolute; ...

If you have a multi-parameter type-class with arguments a, b, c, and x, this extension lets you express that the type x can be uniquely identified from a, b, and c: class SomeClass a b c x | a b c -> x where ... When declaring an instance of such class, it will be checked against all other in...

HTML comments (optionally preceded by whitespace) will cause code (on the same line) to be ignored by the browser also, though this is considered bad practice. One-line comments with the HTML comment opening sequence (<!--): Note: the JavaScript interpreter ignores the closing characters of H...

There are two ways to define functions with multiple parameters in F#, Curried functions and Tupled functions. let curriedAdd x y = x + y // Signature: x:int -> y:int -> int let tupledAdd (x, y) = x + y // Signature: x:int * y:int -> int All functions defined from outside F# (such as ...

The term 'heap' is a general computing term meaning an area of memory from which portions can be allocated and deallocated independently of the memory provided by the stack. In C++ the Standard refers to this area as the Free Store which is considered a more accurate term. Areas of memory allocate...
