To copy a texture to the device there are two steps necessary
Allocate the memory on the device
Copy the image to the device
_mem = clCreateImage2D($context, $mem_flags, $image_format, $width, $height, $stride, $source, &err);
The $mem_flags define how the memory is allocated. It can...
DRF offers the chance to further customize the behavior of the generic views/viewsets by allowing the creation of custom mixins.
How to:
To define a custom mixin we just need to create a class inheriting from object.
Let's assume that we want to define two separate views for a model named MyM...
To fix entities onto the camera such that they stay within view no matter where the user looks, you can attach those entities as a child of the camera. Use cases might be a heads-up display (HUD).
<a-entity camera look-controls>
<a-entity geometry="primitive: plane; height: 0.2; wi...
Let's assume we have a search results page that displays a user's search query back to them. The code below is an example of how this could be done in PHP:
Results for "<?php echo $_GET['query'] ?>"
For this to work, you would access the page with a URL like:
https://yoursite.te...
In this example, we take a sine curve plot and add more features to it; namely the title, axis labels, title, axis ticks, grid and legend.
# Plotting tutorials in Python
# Enhancing a plot
import numpy as np
import matplotlib.pyplot as plt
x = np.linspace(0, 2.0*np.pi, 101)
y = np.sin(x)

The following are some of the common extensions used in Fortran source files and the functionalities they can work on.
Lowercase f in the extension
These files do not have the features of preprocessor directives similar to C-programming language. They can be directly compiled to create object file...
Because Node.js runs on a single process uncaught exceptions are an issue to be aware of when developing applications.
Silently Handling Exceptions
Most of the people let node.js server(s) silently swallow up the errors.
Silently handling the exception
process.on('uncaughtException', functio...
Fixed-width files are text files in which columns are not separated by any character delimiter, like , or ;, but rather have a fixed character length (width). Data is usually padded with white spaces.
An example:
Column1 Column2 Column3 Column4Column5

As recently Apple rolled out iOS11 and Xcode-9, we can now debug apps on devices without connecting devices to Xcode through USB.
We can take advantage of wireless debugging feature added to this Xcode-9.
To enable wireless debugging, we have to configure some steps in Xcode.
1 First connect the ...
Given a rod of length n inches and an array of length m of prices that contains prices of all pieces of size smaller than n. We have to find the maximum value obtainable by cutting up the rod and selling the pieces. For example, if length of the rod is 8 and the values of different pieces are given ...
As it can be seen from the picture above, on a single application we can create:
Multiple databases
Each database can have multiple object stores (tables)
Each object store can have stored multiple objects
There are two steps that the code from example 1 carried out: one was tokenizing the input, which means it looked for symbols that constitute the arithmetic expression, and the second step was parsing, which involves analysing the extracted tokens and evaluating the result.
This section provides a ...
This method extends the jQuery prototype ($.fn) object to provide new custom methods that can be chained to the jQuery() function.
For example:
<div>Hello</div>
<div>World!</div>
<script>
jQuery.fn.extend({
// returns combination of div texts as a result
g...
Ok, so now you have your layer designed! This is how you define it in your .prototxt file:

name: "LayerName"
type: "Python"
top: "TopBlobName"
bottom: "BottomBlobName"
python_param {
module: "My_Custom_Layer_File"

Softmax regression (or multinomial logistic regression) is a generalization of logistic regression to the case where we want to handle multiple classes. It is particularly useful for neural networks where we want to apply non-binary classification. In this case, simple logistic regression is not suf...
