VideoWriter videoWriter; videoWriter = new VideoWriter(outputFile, VideoWriter.fourcc('x', '2','6','4'), fps, frameSize, isRGB); //We have stated that we will use x264 as codec with FourCC //For writing, we add the following method and it will write the image we give as parameter...

This example is based on spring boot 1.5.1.RELEASE. with the following dependencies: <!-- Spring --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <dependency>...

Let's say we want to eliminate duplicated subsequence element from a string (it can be more than one). For example: 2,14,14,14,19 and convert it into: 2,14,19 Using gsub, we can achieve it: gsub("(\\d+)(,\\1)+","\\1", "2,14,14,14,19") [1] "2,14,19" ...

It is a common practice to name files using the date as prefix in the following format: YYYYMMDD, for example: 20170101_results.csv. A date in such string format can be verified using the following regular expression: \\d{4}(0[1-9]|1[012])(0[1-9]|[12][0-9]|3[01]) The above expression considers d...

Instead of invoking the Angular’s bootstrap code directly, wrap the bootstrap code into a function and export the function. This function can also accept parameters. import { platformBrowserDynamic } from "@angular/platform-browser-dynamic"; import { AppModule } from "./src/app&quot...

In android, every developer uses Anonymous Class (Runnable) at least once in a project. Any Anonymous Class has a reference to its parent (activity). If we perform a long-running task, the parent activity will not be destroyed until the task is ended. Example uses handler and Anonymous Runnable cla...

Sometimes you would want to start or remove an action on a specific node at a certain time. For example, you might want to stop a moving object when the user taps the screen. This becomes very helpful when a node has multiple actions and you only wants to access one of them. let move = SKAction.mov...

Task<T> is a class and causes the unnecessary overhead of its allocation when the result is immediately available. ValueTask<T> is a structure and has been introduced to prevent the allocation of a Task object in case the result of the async operation is already available at the time of...

Type Families are not necessarily injective. Therefore, we cannot infer the parameter from an application. For example, in servant, given a type Server a we cannot infer the type a. To solve this problem, we can use Proxy. For example, in servant, the serve function has type ... Proxy a -> Server...

Retrolambda lets you run Java 8 code with lambda expressions, method references and try-with-resources statements on Java 7, 6 or 5. It does this by transforming your Java 8 compiled bytecode so that it can run on an older Java runtime. Backported Language Features: Lambda expressions are back...

Adding a video that will autoplay on a loop and has no controls or sound. Perfect for a video header or background. <video width="1280" height="720" autoplay muted loop poster="video.jpg" id="videobg"> <source src="video.mp4" type="...

It is known for a while that dealing with loops in Blade has been limited, as of 5.3 there is a variable called $loop available @foreach($variables as $variable) // Within here the `$loop` variable becomes available // Current index, 0 based $loop->index; // Current ite...

wire a; wire b; reg q; always @(a) // b missing from sensativity list q = a & b; // In simulation q will change only when a changes In hardware, q will change whenever a or b changes.

Each attribute is associated with a component count, type, normalized, offset, stride and VBO. The VBO is no passed explicitly as a parameter but is instead the buffer bound to GL_ARRAY_BUFFER at the time of the call. void prepareMeshForRender(Mesh mesh){ glBindVertexArray(mesh.vao); glBi...

4.3 OpenGL 4.3 (or ARB_separate_attrib_format) adds an alternative way of specifying the vertex data, which creates a separation between the format of the data bound for an attribute and the buffer object source that provides the data. So instead of having a VAO per mesh, you may have a VAO per ver...
