You can also use Laravel Artisan commands from your routes or controllers. To run a command using PHP code: Artisan::call('command-name'); For example, Artisan::call('db:seed');

Code coverage is a measure used to how often each source code statement and branch is executed. This measure is usually required when running a test suite to ensure that as much of the code as possible is tested by the test suite. It can also be used during profiling to determine code hot-spots and ...

We can use the unit type as a function argument to define functions that we don't want executed until later. This is often useful in asynchronous background tasks, when the main thread may want trigger some predefined functionality of the background thread, like maybe moving it to a new file, or if...

Since vim version 7.3 the feature 'persistent_undo' is supported, which makes it possible do undo/redo changes, even after closing vim or restarting your computer. It's possible to configure it by adding the following to your vimrc, but first create a directory, where your undofiles should be saved...

Suppose that we have a text and a pattern. We need to determine if the pattern exists in the text or not. For example: +-------+---+---+---+---+---+---+---+---+ | Index | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | +-------+---+---+---+---+---+---+---+---+ | Text | a | b | c | b | c | g | l | x | +-------...

Suppose we have an array: +-------+-----+-----+-----+-----+-----+-----+ | Index | 0 | 1 | 2 | 3 | 4 | 5 | +-------+-----+-----+-----+-----+-----+-----+ | Value | -1 | 3 | 4 | 0 | 2 | 1 | +-------+-----+-----+-----+-----+-----+-----+ We want to perform some query on thi...

This is just a small hack for those who use self-defined functions often. Type "fun" RStudio IDE and hit TAB. The result will be a skeleton of a new function. name <- function(variables) { } One can easily define their own snippet template, i.e. like the one below ...

Redis has a Windows port provided by 'Microsoft Open Technologies'. You can use the msi installer found on: https://github.com/MSOpenTech/redis/releases After installation completes you can see 'Redis' is a Windows service (and it's status should be "Started") To write an 'Hello world'...

Dynamic programming solves problems by combining the solutions to subproblems. It can be analogous to divide-and-conquer method, where problem is partitioned into disjoint subproblems, subproblems are recursively solved and then combined to find the solution of the original problem. In contrast, dyn...

Eloquent relationships are defined as functions on your Eloquent model classes. Since, like Eloquent models themselves, relationships also serve as powerful query builders, defining relationships as functions provides powerful method chaining and querying capabilities. For example, we may chain addi...

Method Overriding and Overloading are two forms of polymorphism supported by Java. Method Overloading Method overloading (also known as static Polymorphism) is a way you can have two (or more) methods (functions) with same name in a single class. Yes its as simple as that. public class Shape{ ...

Dynamic Time Warping(DTW) is an algorithm for measuring similarity between two temporal sequences which may vary in speed. For instance, similarities in walking could be detected using DTW, even if one person was walking faster than the other, or if there were accelerations and decelerations during ...

In general, we tend to back up the DB with the pgAdmin client. The following is a sh script used to save the database (under linux) in two formats: SQL file: for a possible resume of data on any version of PostgreSQL. Dump file: for a higher version than the current version. #!/bin/sh...

int x, y; bool ready = false; void init() { x = 2; y = 3; ready = true; } void use() { if (ready) std::cout << x + y; } One thread calls the init() function while another thread (or signal handler) calls the use() function. One might expect that the use() function ...

The IE=Edge meta tag is for telling the destination rendering engine to use the latest (edge) version of IE rendering engine, which enables responsive behavior in Windows phones. <meta http-equiv="X-UA-Compatible" content="IE=edge"> Occasionally this breaks images in Li...
