Although the 8086 was most used in IBM PCs along with Microsoft, there were a number of other computers and Operating Systems that used it too: most notably Unix. That was a product of AT&T, and it already had Unix running on a number of other architectures. Those architectures used more convent...

Borland started out with a Pascal compiler that they called "Turbo Pascal". This was followed by compilers for other languages: C/C++, Prolog and Fortran. They also produced an assembler called "Turbo Assembler", which, following Microsoft's naming convention, they called "T...

When the GNU project needed an assembler for the x86 family, they went with the AT&T version (and its syntax) that was associated with Unix rather than the Intel/Microsoft version.

NASM is by far the most ported assembler for the x86 architecture - it's available for practically every Operating System based on the x86 (even being included with MacOS), and is available as a cross-platform assembler on other platforms. This assembler uses Intel syntax, but it is different from ...

YASM is a complete rewrite of NASM, but is compatible with both Intel and AT&T syntaxes.

Suppose that you have a pointer to an object of a polymorphic class: Shape *ps; // see example on defining a polymorphic class ps = get_a_new_random_shape(); // if you don't have such a function yet, you // could just write ps = new Square...

Background pages are implicit pages which contain background scripts. A background script is a single long-running script to manage some task or state. It exists for the lifetime of your extension, and only one instance of it at a time is active. You can declare it like this in your manifest.json: ...

A content script is extension code that runs alongside a normal page. They have full access to the web page's DOM (and are, in fact, the only part of the extension that can access a page's DOM), but the JavaScript code is isolated, a concept called Isolated World. Each extension has its own content...

Loop control statements are used to change the flow of execution from its normal sequence. When execution leaves a scope, all automatic objects that were created in that scope are destroyed. The break and continue are loop control statements. The break statement terminates a loop without any furthe...

Save with default parameters: df.to_csv(file_name) Write specific columns: df.to_csv(file_name, columns =['col']) Difault delimiter is ',' - to change it: df.to_csv(file_name,sep="|") Write without the header: df.to_csv(file_name, header=False) Write with a given head...

Got to Tools | Options | Source Control | Visual Studio Team Foundation Server click on the Configure User Tools: You can add separate overrides for 'Compare' and 'Merge' operations. Click on Add and select the operation you want to override. You'd need to type the path to the tool you use, and ...

An extensible derived type may be abstract type, abstract :: base_type end type Such a derived type may never be instantiated, such as by type(base_type) t1 allocate(type(base_type) :: t2) but a polymorphic object may have this as its declared type class(base_type), allocatable :: t1 o...

A derived type is extensible if it has neither the bind attribute nor the sequence attribute. Such a type may be extended by another type. module mod type base_type integer i end type base_type type, extends(base_type) :: higher_type integer j end type higher_type end ...

In order to get a view to slowly fade in or out of view, use an ObjectAnimator. As seen in the code below, set a duration using .setDuration(millis) where the millis parameter is the duration (in milliseconds) of the animation. In the below code, the views will fade in / out over 500 milliseconds, o...

var a:Number=0.123456789; trace(a); // 0.123456789 trace(a.toPrecision(4)); // 0.1235 trace(a.toFixed(4)); // 0.1235 trace(a.toExponential(4)); // 1.2345e-1 trace(a.toString(16)); // 0 - works for integer part only var b:Number=12345678.9876543; // a bigg...

Simple form using one variable: for i := 0; i < 10; i++ { fmt.Print(i, " ") } Using two variables (or more): for i, j := 0, 0; i < 5 && j < 10; i, j = i+1, j+2 { fmt.Println(i, j) } Without using initialization statement: i := 0 for ; i < 10; i++ {...

AngularJS directives are what controls the rendering of the HTML inside an AngularJS application. They can be an Html element, attribute, class or a comment. Directives are used to manipulate the DOM, attaching new behavior to HTML elements, data binding and many more. Some of examples of directives...
