Turn from: Pseudo-computer scientist | Real Yard FarmFirst introduce a simple and very practical tool, that is multiprocessing. Pool. If your task can be solved with YS = map (f, XS), as you probably know, this form is inherently the easiest to parallel, it's really easy to compute this task in parallel in Python. For example, put each number squared:1 ImportMultiprocessing2 3 deff (x):4 returnX *x5 6Cores =Multiprocessing.cpu_count ()7Pool = mult

Analysis of problems caused by data of BigDecimal type Problem Description : The program needs to determine whether a field is 0 (the field type is BigDecimal), do not want to think, the object's judgment with equals? The result is a certain gap with the expected, see the code below and the results of the operation. public static void main(String[] args) { BigDecimal decimal1 = BigDecimal.valueOf(0); BigDecimal decimal2 = new BigDecimal("0.00"); System.out.println("the r

A container that implements fixed widths and supports responsive layouts. 当屏幕宽度 > 1200，则页面宽度固定为 1170px当屏幕宽度 992~1200，则页面宽度固定为 970px当屏幕宽度 768~992，则页面宽度固定为 750px当屏幕宽度 2 .container-fluid : Realize the container width is full screen 100%.4. Bootstrap grid system Concept: Bootstrap provides a responsive, mobile-first streaming raster system, which is divided into 12 columns by default as the screen or viewport (viewport) size increases. A raster system is used to create a page layou

city that starts with a letter B:Copy codeThe Code is as follows:SELECT titleFROM titlesWHERE EXISTS(SELECT *FROM publishersWHERE pub_id = titles. pub_idAND city LIKE \ 'B % \') Copy codeThe Code is as follows:SELECT titleFROM titlesWHERE pub_id IN(SELECT pub_idFROM publishersWHERE city LIKE \ 'B % \') Use NOT EXISTSNot exists is opposite to EXISTS. If the subquery does NOT return rows, the WHERE clause in not exists is satisfied. In this example, find the name of the publisher who does not pub

N is produced according to the following rules: NN/2 (NIs even)N3N+ 1 (NIs odd) Example 13: 13 40, 20, 10, 16, 8, 4, 2 1. Find the sequence of which is the longest in the number lower than 1 million. The output sequence contains a lot of previously computed data. Therefore, to cache the data, the following uses a dictionary. Note that when a large number is an odd number, the next number may exceed the maximum value of the type. So the following F # uses int64. Code It's Haskell's direct tr
