Inside a Project configuration, you can Create build configuration: Manually Provide a Name and a Description. The Build Configuration ID is generated from the ProjectName, and the Build Configuration Name's. Once your configuraion is Saved, you can specify a Version Control Settings. This will ...
Usually when generating random numbers it is useful to generate integers within a range, or a p value between 0.0 and 1.0. Whilst modulus operation can be used to reduce the seed to a low integer this uses the low bits, which often go through a short cycle, resulting in a slight skewing of distribut...
// Let's take an arbitrary piece of data, a 4-byte integer in this case let some_data: u32 = 14; // Create a constant raw pointer pointing to the data above let data_ptr: *const u32 = &some_data as *const u32; // Note: creating a raw pointer is totally safe but dereferencing a raw pointe...
// Let's take a mutable piece of data, a 4-byte integer in this case let mut some_data: u32 = 14; // Create a mutable raw pointer pointing to the data above let data_ptr: *mut u32 = &mut some_data as *mut u32; // Note: creating a raw pointer is totally safe but dereferencing a raw pointe...
Unlike normal Rust references, raw pointers are allowed to take null values. use std::ptr; // Create a const NULL pointer let null_ptr: *const u16 = ptr::null(); // Create a mutable NULL pointer let mut_null_ptr: *mut u16 = ptr::null_mut();
Overloading the addition operator (+) requires implement the std::ops::Add trait. From the documentation, the full definition of the trait is: pub trait Add<RHS = Self> { type Output; fn add(self, rhs: RHS) -> Self::Output; } How does it work? the trait is implemented for...

Heap sort is a comparison based sorting technique on binary heap data structure. It is similar to selection sort in which we first find the maximum element and put it at the end of the data structure. Then repeat the same process for the remaining items. Pseudo code for Heap Sort: function heapsor...
Note: at is not installed by default on most of modern distributions. To execute a job once at some other time than now, in this example 5pm, you can use echo "somecommand &" | at 5pm If you want to catch the output, you can do that in the usual way: echo "somecommand > o...

The following documentation describes both MySQLi and PDO supported pagination solution. Go to https://github.com/rajdeeppaul/Pagination and download pagination.php file into your project directory. Let's say your directory structure looks like this: project directory | |--paginati...
There are quite a number situations where one has huge amounts of data and using which he has to classify an object in to one of several known classes. Consider the following situations: Banking: When a bank receives a request from a customer for a bankcard, the bank has to decide whether to issue...

Let's say we have 8 houses. We want to setup telephone lines between these houses. The edge between the houses represent the cost of setting line between two houses. Our task is to set up lines in such a way that all the houses are connected and the cost of setting up the whole connection is mini...
