Why annotations? Generally we use annotation to facilitate the development and to make the code more clear and clean. What are annotations? Java 5 annotations provide standardization of metadata in a general goal. This metadata associated with Java features can be exploited in the compilation or ...

1 dimensional To integrate a one dimensional function f = @(x) sin(x).^3 + 1; within the range xmin = 2; xmax = 8; one can call the function q = integral(f,xmin,xmax); it's also possible to set boundarys for relative and absolute errors q = integral(f,xmin,xmax, 'RelTol',10e-6, 'AbsTo...

If you have an elixir file; a script or a module and want to load it into the current IEx session, you can use the c/1 method: iex(1)> c "lib/utils.ex" iex(2)> Utils.some_method This will compile and load the module in IEx, and you'll be able to call all of it's public methods. ...

// If you find yourself doing something like this... function fieldChanged(type, name, index) { if (name == 'salesrep') { var salesRepId = nlapiGetFieldValue('salesrep'); var salesRepEmail = nlapiLookupField('employee', salesRepId, 'email'); nlapiSetFieldValue('custb...

It is a basic human instinct to assess risk and to accept or take some kind of action on that risk. This is the essence of security, which is the body of knowledge that provides a framework around this instinct. Security defines three key concepts in a triangular paradigm - Confidentiality, Integri...

We initialize the data we want to interpolate: x = 0:0.5:10; y = sin(x/2); This means the underlying function for the data in the interval [0,10] is sinusoidal. Now the coefficients of the approximating polynómials are being calculated: p1 = polyfit(x,y,1); p2 = polyfit(x,y,2); p3 = polyfit(...

I would venture to say that 80% of the processing that goes on in modern computing systems does not require user interaction, such as kernel code for Linux, OSX and Windows. For those that do, there are two fundamentals which are interactivity via keyboard (pointing devices) and console. This exampl...

Spring is a vast framework, so the Spring framework has been divided in several modules which makes spring lightweight. Some important modules are: Spring Core Spring AOP Spring JDBC Spring Transaction Spring ORM Spring MVC All the modules of Spring are independent of each other except S...

You can always run JavaScript from inside itself, although this is strongly discouraged due to the security vulnerabilities it presents (see Remarks for details). To run JavaScript from inside JavaScript, simply use the below function: eval("var a = 'Hello, World!'");

The queue is a FIFO (first-in, first-out) data-structure, i.e. the first element added to the queue will be the first element removed ("first out"). Let us consider the example of customers waiting to be helped. Alice, Bob, and Dan are all at the supermarket. Alice is ready to pay, so she...

Prolog features exceptions, which are part of the Prolog ISO standard. An exception can be thrown with throw/1, and caught with catch/3. The ISO standard defines many cases in which errors must or may be thrown. The standardized exceptions are all of the form error(E,_), where E indicates the erro...

Set this attribute in your manifest's or element to enable or disable multi-window display: android:resizeableActivity=["true" | "false"] If this attribute is set to true, the activity can be launched in split-screen and freeform modes. If the attribute is set to false, the...

To Convert you date in dd/MM/yyyy format into milliseconds you call this function with data as String public long getMilliFromDate(String dateFormat) { Date date = new Date(); SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); try { date = formatter.p...

In this context, using the this pointer isn't entirely necessary, but it will make your code clearer to the reader, by indicating that a given function or variable is a member of the class. An example in this situation: // Example for this pointer #include <iostream> #include <string>...

This is an actual useful strategy to differentiate member data from parameters... Lets take this example : // Dog Class Example #include <iostream> #include <string> using std::cout; using std::endl; /* * @class Dog * @member name * Dog's name * @function bark * ...

Variables can be used in string interpolation. This allows you to dynamically generate selectors, properties and values. And the syntax for doing so a variable is #{$variable}. $className: widget; $content: 'a widget'; $prop: content; .#{$className}-class { #{content}: 'This is #{$content}'...

Graph Theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects. Did you know, almost all the problems of planet Earth can be converted into problems of Roads and Cities, and solved? Graph Theory was invented many years ago, even before the in...
