In previous installments, I have begun to introduce the harvesting of domain idiomatic patterns (solutions for urgent business problems) by using domain-specific languages. For this task, DSL work is good because they are concise (with as few noisy syntax as possible) and readable (even by developers), and they stand out from more API-centric code. In the previous issue, I had shown how to use Groovy to build a DSL to take advantage of some of its features. In this section, I'll end the discussi

The evolutionary path of Java application architecturesWhen we set up a system, we usually need to think about how to interact with other systems, so we first need to know how the various systems interact with each other and what technology is implemented.1. Interactions between different languages of different systemsNow we commonly use webservice,http requests for interaction between different languages of different systems. WebService, or "Web serv

If the ML evolutionary tree is to be validated for high bootstrap values, the computational power requirement is high. Not parallel do basic impossible.So under a raxml, under Linux there are several ways to compile, look at the hands of the machine to support the AVX instruction set, so choose Avx-mpi way.Install Openmpi First, according to the online tutorial compiled on line, is slightly slow.But after the installation of MPICC, and then to compile

During agile development, do we still need to design the system architecture? In fact, Martin Fowler Dead? The answer is that we cannot ignore the design of the system architecture. Planned Design) different, we need an evolutionary design (evolutionary Design ). In the lifecycle of agile development, each iteration is used to enrich and update our design scheme so that it can meet the customer's require

The evolutionary design cannot be implemented in one step. It works as perfectly as planned to achieve the expected results as it fits the design of a building. many of the Construction bridges went bankrupt and rebuilt in the planned design model. At the beginning, the designers did not think that Zhongshan Avenue in Guangzhou would be congested. This is a failure of the plan design, I always thought that the demand changes were limited, and the city

First, the evolutionary history of programming languages: Machine language assembly language high-level languages1. Machine language:(1) The computer can only accept binary code, the instructions described in binary code 0 and 1 are called machine instructions, and the set of all machine instructions forms the machine language of the computer.(2) Machine language belongs to low-level language.2. Assembly Language:(1) In fact, the same quality and mach

Problem DescriptionAs is known to all, sepr (Liangjing Wang) had solved more than 1400 problems on POJ, but nobody know the days and nights he had spent on solving problems.Xiangsanzi (Chen Zhou) was a perfect problem solver too. Now this is a story about them happened two years ago.On March 2006, sepr Xiangsanzi were new comers of hustacm team and both of them want to be "The Best New Comers of March", so they spent days and nighthts solving problem

have been processed several times there is a certain pixel difference, or there may be a watermark.After solving the target position of the slider, are we just going to follow the displacement to drag the slider? The answer is no, look:You can see that there is a distance between the slider and the background image before sliding, it is necessary to make a displacement adjustment, after observation, this value is about 7 pixels, so: the final sliding displacement = the number of left pixels of
