called the host byte order. 2. When the formatted data (32bit or 16bit) A problem occurs between two hosts with different byte-order 2.1 solution: The sending side always converts the data to be sent to big endian in the send, the receiver knows that the data is always big endian byte order, so the receiver can decide whether to convert (small segment conversion, big endian byte sequence does not convert) according to its own situation 3. Endian byte order Network byte order 4. Process byte pro

Calculation frequency:Given a sequence T:hist = {}For x in T:HIST[X] = Hist.get (x,0) +1The result is a dictionary that maps the value to its frequency. Divide it by N to convert the frequency into frequencies, which is called normalization:n = float (len (t))PMF = {}For X, freq in Hist.items ():PMF[X] = freq/nTo draw a histogram:Vals, Freqs = Hist.

/*Chararraywriter implements the output stream with arrays as the target. Chararraywriter has two constructor functions: chararraywriter () chararraywriter (INT numchars) in the first form. A buffer of the default length is created. Second, the buffer length is specified by numchars. The buffer is stored in the Buf member of chararraywriter. The buffer size can automatically increase as needed. The number of characters maintained by the buffer is included in the count member of chararraywriter.

After Apache is started, five idle sub-processes are waiting to accept the request. You can also refer to minsparese

)] GenerallyNUnit vector. For quaternion, four values can be used to record rotation, rather than the sixteen values required by matrix. Why is it convenient to use quaternion to calculate rotation? First, quaternion is a plural number. If you still remember a little complex number knowledge, you should know that the geometric meaning of the plural multiplication (Cross multiplication) is actually to rotate the plural number. For the simplest plural P = x + yi, if it is multiplied by another p

we will create a store that uses an AJAX proxy. As a preparation, we build a model:Ext.define (' User ', { ' Ext.data.Model ', fields : [' id ', ' name ', ' email ')}); // The Store contains the ajaxproxy as an inline configuration var store = ext.create (' Ext.data.Store ', { ' User ', proxy: { ' ajax '), ' Users.json '} ); Store.load ();Our example are going to load user data into a Store, so we start off by defining a Model with the fields that we expect th e Se
