ng-repeat is the built-in directive provided by AngularJS, mostly used for listing the array elements on UI dynamically as per the changes in our model. Official "ng-repeat" docs can be found at : https://docs.angularjs.org/api/ng/directive/ngRepeat Also the most common error faced whil...

There are times when the framework's Random() class may not be considered random enough, given that it is based on a psuedo-random number generator. The framework's Crypto classes do, however, provide something more robust in the form of RNGCryptoServiceProvider. The following code samples demonstr...

Let's say a user wants to select data from different tables. A table is specified by the user. function get_value(p_table_name varchar2, p_id number) return varchar2 is value varchar2(100); begin execute immediate 'select column_value from ' || p_table_name || ...

Example below inserts value into the table from the previous example: declare query_text varchar2(1000) := 'insert into my_table(id, column_value) values (:P_ID, :P_VAL)'; id number := 2; value varchar2(100) := 'Bonjour!'; begin execute immediate query_text using id, value; end; / ...

Let's update table from the first example: declare query_text varchar2(1000) := 'update my_table set column_value = :P_VAL where id = :P_ID'; id number := 2; value varchar2(100) := 'Bonjour le monde!'; begin execute immediate query_text using value, id; end; /

This code creates the table: begin execute immediate 'create table my_table (id number, column_value varchar2(100))'; end; /

You can execute anonymous block. This example shows also how to return value from dynamic SQL: declare query_text varchar2(1000) := 'begin :P_OUT := cos(:P_IN); end;'; in_value number := 0; out_value number; begin execute immediate query_text using out out_value, in in_value; dbms_o...

This example shows an efficient way of calculating power using template metaprogramming. template <int base, unsigned int exponent> struct power { static const int halfvalue = power<base, exponent / 2>::value; static const int value = halfvalue * halfvalue * power<base, e...

The machine learns to predict an output when given an input. Each training case consists of an input and a target output. Regression The target ouput takes continuous values. Predicting the price of a stock Predicting a house price Classification The target output is a class label. Wha...

Unsupervised learning allows us to approach problems with little or no idea what our results should look like. We can derive structure from data where we don't necessarily know the effect of the variables. The most common type of unsupervised learning is cluster analysis or clustering. It is the ta...

Many modern Image Processing algorithms use patches are their basic element to work on. For instance one could denoise patches (See BM3D Algorithm). Yet when building the image form the processed patches we have many results for the same pixel. One way to deal with it is taking the average (Empir...

There are two ways to push an element to an array: array_push and $array[] = The array_push is used like this: $array = [1,2,3]; $newArraySize = array_push($array, 5, 6); // The method returns the new size of the array print_r($array); // Array is passed by reference, therefore the original ar...
