A good and easy alternative to the flawed rand() procedures, is xorshift, a class of pseudo-random number generators discovered by George Marsaglia. The xorshift generator is among the fastest non-cryptographically-secure random number generators. More information and other example implementaions ar...

call :FunctionX rem More code... :FunctionX rem Some code here. goto :eof This is a very simple function. Functions are in-program commands that do multiple commands at a time. Functions are made by creating a label and putting code in it, and once it is done, you add a goto :eof or exit ...

call :tohex 14 result rem More code... :tohex <innum> <outvar> set dec=%1 set outvar=%~2 rem %n and %~n are functionally identical, but %~n is slightly safer. goto :eof This takes the additional parameters from the call as if the function was a separate Batch file. Note: the ...

For this demonstration we will use service broker construction created in another part of this documentation. Mentioned part is called 3. Create basic service broker construction on database (single database communication). First we need to create a procedure that is able to read and process data f...

npm install --global yarn If you didn't have npm installed before, check there website documentation for more details. https://yarnpkg.com/en/docs/install

For the most of it, if you know NPM, you’re already set! That adds a ‘package.json’ file in the root of your project npm init === yarn init These are all the same: npm link === yarn link npm outdated === yarn outdated npm publish === yarn publish npm run === yarn run npm cache clean === ya...

BeautifulSoup allows you to filter results by providing a function to find_all and similar functions. This can be useful for complex filters as well as a tool for code reuse.

To illustrate how to use regr_slope(Y,X), I applied it to a real world problem. In Java, if you don't clean up memory properly, the garbage can get stuck and fill up the memory. You dump statistics every hour about memory utilization of different classes and load it into a postgres database for anal...

Lets first understand the problem, consider this figure- We want to calculate ϴ, where we know A, B & O. Now, if we want to get ϴ, we need to find out α and β first. For any straight line, we know- y = m * x + c Let- A = (ax, ay), B = (bx, by), and O = (ox, oy). So for the line OA- oy =...

Content Negotiation can be defined as the process of selecting best representation for a given resource. So Content negotiation means the client and server can negotiate between them so that client can get data according to their required format. There are three points on which internet depends, ...

ls() includes a type flag, which lets you find scene nodes of a particular type. For example: cameras = cmds.ls(type='camera') // [u'topShape', u'sideShape', u'perspShape', u'frontShape'] You can search for multiple types in the same call: geometry = cmds.ls(type=('mesh', 'nurbsCurve', 'nu...

When a Component is resolved from the Windsor container it must have a definition of the scope it is in. By scope meaning if and how it is reused and when to release the object for the Garbage Collector to destroy. This is the LifeStlye of the Component. The way to specify a LifeStyle is by registe...

By implementing your custom IScopeAccessor you can create different types of scopes. For the following example I have the two classes Foo and Bar in which Bar will be registered with a custom LifeStyle. Each have an Id to assist with testing public class Foo { public Guid FooId { get; } = G...

Define a new basic command A macro can be defined using \newcommand. For example: \newcommand{\foo}{Just foo, you see?} defines a macro \foo that expands to Just foo, you see?. It can then be used like any built-in command, for example after that definition: He said: ``\foo'' expands to He...
