There are many ways to communicate with servers using Unity as the client (some methodologies are better than others depending on your purpose). First, one must determine the need of the server to be able to effectively send operations to and from the server. For this example, we will send a few pie...

Executable JAR files are the simplest way to assemble Java code into a single file that can be executed. *(Editorial Note: Creation of JAR files should be covered by a separate Topic.) * Assuming that you have an executable JAR file with pathname <jar-path>, you should be able to run it as f...

An NSPredicate can use substitution variables to allow values to be bound on the fly. Objective-C NSPredicate *template = [NSPredicate predicateWithFormat: @"self BEGINSWITH $letter"]; NSDictionary *variables = @{ @"letter": @"r" }; NSPredicate *beginsWithR = [templ...

Objective-C NSArray *heroes = @[@"tracer", @"bastion", @"reaper", @"junkrat", @"roadhog"]; NSPredicate *template = [NSPredicate predicateWithFormat:@"self BEGINSWITH $letter"]; NSDictionary *beginsWithRVariables = @{ @"letter&qu...

In Julia, you can have an Array that holds other Array type objects. Consider the following examples of initializing various types of Arrays: A = Array{Float64}(10,10) # A single Array, dimensions 10 by 10, of Float64 type objects B = Array{Array}(10,10,10) # A 10 by 10 by 10 Array. Each ele...

We can use the [] to create an empty Array in Julia. The simplest example would be: A = [] # 0-element Array{Any,1} Arrays of type Any will generally not perform as well as those with a specified type. Thus, for instance, we can use: B = Float64[] ## 0-element Array{Float64,1} C = Array{Flo...

In Julia, as in many other languages, it is possible to interpolate by inserting values defined by variables into strings. For a simple example: n = 2 julia> MyString = "there are $n ducks" "there are 2 ducks" We can use other types than numeric, e.g. Result = false j...

If you have void F1(MyType1 x) { // do something } void F1(MyType2 x) { // do something else } and for some reason you need to call the first overload of F1 but with x = null, then doing simply F1(null); will not compile as the call is ambiguous. To counter this you can do F1...

The Deque is the only Python data structure with fast Queue operations. (Note queue.Queue isn't normally suitable, since it's meant for communication between threads.) A basic use case of a Queue is the breadth first search. from collections import deque def bfs(graph, root): distances = {}...

After finding an official Julia package, it is straightforward to download and install the package. Firstly, it's recommended to refresh the local copy of METADATA: julia> Pkg.update() This will ensure that you get the latest versions of all packages. Suppose that the package we want to inst...

Using an AppCompat theme, the ProgressBar's color will be the colorAccent you have defined. 5.0 To change the ProgressBar color without changing the accent color you can use theandroid:theme attribute overriding the accent color: <ProgressBar android:theme="@style/MyProgress" ...

According to Material Documentation: A linear progress indicator should always fill from 0% to 100% and never decrease in value. It should be represented by bars on the edge of a header or sheet that appear and disappear. To use a material Linear ProgressBar just use in your xml: <Progres...

Julia Symbol literals must be legal identifiers. This works: julia> :cat :cat But this does not: julia> :2cat ERROR: MethodError: no method matching *(::Int64, ::Base.#cat) Closest candidates are: *(::Any, ::Any, ::Any, ::Any...) at operators.jl:288 *{T<:Union{Int128,Int16,Int...

This is a continuation of the "main class" and "executable JAR" examples. Typical Java applications consist of an application-specific code, and various reusable library code that you have implemented or that has been implemented by third parties. The latter are commonly referr...

Search for a lemma when you know what its conclusion ought to be: Coq < SearchPattern (S _ <= _). le_n_S: forall n m : nat, n <= m -> S n <= S m You can also search on a partial conclusion (the conclusion and one or several last hypotheses). Coq < Require Import Arith. Coq &...

Consider this CSV data: #id,title,text 1,hello world,"This is a ""blog""." 2,second time,"My second entry." This data can be read with the following code: // r can be any io.Reader, including a file. csvReader := csv.NewReader(r) // Set comment char...

How does an RDD gets partitioned? By default a partition is created for each HDFS partition, which by default is 64MB. Read more here. How to balance my data across partitions? First, take a look at the three ways one can repartition his data: Pass a second parameter, the desired min...
