1. Install the Go package under Windows, download the address Http://www.golangtc.com/download
2. Set the GOPATH environment variable, the PROTOBUF obtained from GitHub will be downloaded to the Gopath directory
3. Install the GIT package, https://git-scm.com/downloads/
4. Add the path of the GIT.exe in the path variable D:\Program files\git\bin (choose the path you installed yourself)

1. OverviewGenerator is a new data type introduced by ES6 and looks like a function that yields can be returned multiple times, in addition to returning with return.Generator is defined by the function*, (note the * number),2. ExampleFunctions cannot save state, sometimes global variables are required to hold numbers;2.1' Use strict ';functionnext_id () {varID = 1; while(id) {yield id; ID++; } returnID;}//Test:varx, pass=true, G=next_id (); for(x = 1; x ) { if(G.next ().

Classification of Java Heap
Divided into two categories: Younggen and Oldgen. Among them, Younggen is divided into three parts: Eden,from survivor and to survivor, the proportional default is: 8:1:1
PermGen does not belong to the Java heap category It is important to note that, starting with Java8, PermGen has been canceled and replaced by Metaspace, with the difference: PermGen contains class Metadata,class static variable and interned string, But Metaspace has only class metadata,

PHP5.4 can already bind a method to an object and make it simpler in PHP7:
Class HelloWorld{Private $greeting = "Hello";}$closure = function ($whom) {echo $this->greeting. ' ' . $whom; }$obj = new HelloWorld ();$closure->call ($obj, ' world '); Hello WorldGrouping with use statements
The USE statement can only be written before PHP7.

Python's yield keyword Many people may not be very familiar with, the first to know that the keyword is to look at Xrange's document, which mentions yield. Later began to use Tornado, Tornado asynchronous mode of interest, also turned a tornado source, a lot of things are still smattering.Recently turned over the Python source code, looked at the yield realization, found that the principle is very simple!The simplest usage: def Simple_yield (start): N = start while yield n n + = 1if __
function's return value:function Makerangebygenerator ($range) { for ($i = 0; $i $range; $i++) { yield $i; } return "Finish yielding";}
When iterating through all the elements of generator, we can read the return value of the generator through the Getreturn () method:$gen = makeRangeByGenerator(100);foreach ($gen as $i) { echo $i.‘echo $gen->getReturn();*
Question:I wrote a function that uses a random number generator that generates an integer random number as a parameter. Then a function is written to generate a random number generator with different distributions based on parameters for the previous function. I called some random number generation functions of the boost library based on the specific probability distribution, but many functions produce the double type.
My function defines the random number generator as boost: function
