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...
The backup menu is in the Administration Panel.
And in the Left menu, inside the Server Administration, go on Backup.
TeamCity (as of v10) does not automatically backup, but you can get TeamCity to back itself up on a daily basis by scheduling a task to hit the REST api. Typically you would also n...
// 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

// Create a mutable raw pointer pointing to the data above

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();
Rust has a default formatter for pointer types that can be used for displaying pointers.
use std::ptr;
// Create some data, a raw pointer pointing to it and a null pointer
let data: u32 = 42;
let raw_ptr = &data as *const u32;
let null_ptr = ptr::null() as *const u32;
// the {:p} mappi...
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:

Presumably the simplest way to use compose is with a View only. This allows you to include HTML templates without the need to declare a ViewModel with bindable properties for each of them, making it easier to reuse smaller pieces of HTML.
The BindingContext (ViewModel) of the View will be set to th...
Using compose with a View, ViewModel and Model is an easy way to reuse and combine different Views and ViewModels.
Given the following View and ViewModel (applies to each alternative below):

</template>

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...

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:
