The StandardClaim is embedded in the custom type to allow for easy encoding, parsing and validation of standard claims. tokenString := "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJmb28iOiJiYXIiLCJleHAiOjE1MDAwLCJpc3MiOiJ0ZXN0In0.HE7fK0xOQwFEr4WDgRWj4teRPZ6i3GLwD5YCm6Pwu_c" type MyCustomCla...

The StandardClaims type is designed to be embedded into your custom types to provide standard validation features. You can use it alone, but there's no way to retrieve other fields after parsing. See the custom claims example for intended usage. mySigningKey := []byte("AllYourBase") //...

For C# there exist many wrappers that offer an interface to communicate with OpenCL. OpenCL.NET: This is one of the most low level wrappers out there. It offers a complete implementation of the OpenCL API for C# without adding any abstraction at all. So C\C++ examples are easily ported for this ...

Atom is versatile and flexible text editor and has hundreds of community-made, open-source packages that can compile and run source files, for many languages. This guide will show how easy it is to code Python with the Atom editor. This guide assumes you do not have Python nor Atom installed in you...

The key of parallelism is to use multiple threads to solve a problem (duh.) but there are some differences to classical multithreaded programming in how threads are organized. First lets talk about your typical GPU, for simplicities sake I'll focus on A GPU has many processing cores, which make it...

The typical scenario for your memory usage is to store the source data and the processed data in the global memory. When a threadblock starts, it first copies all relevant parts into the shared memory before getting their parts into the registers. Memory access latency also depends on your memory s...

OpenCL Kernels can be either executed on the GPU or the CPU. This allows for fallback solutions, where the customer may have a very outdated system. The programmer can also choose to limit their functionality to either the CPU or GPU. To get started using OpenCL, you'll need a 'Context' and a 'Devi...

To initiate any operation on your devices, you'll need a command queue for each device. The Queue keeps track of different calls you did to the target device and keeps them in order. Most commands can also be executed either in blocking or non-blocking mode. Creating a queue is pretty straightforwa...

scons describes running phases itself. Running it over an empty SConstruct yields this: $ scons scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... scons: `.' is up to date. scons: done building targets. To suppress phase messages, add -Q op...
