Write in front　　From the beginning to write code to now, has done several projects, BS and CS have, has always been a code of farming. However, as a progressive programmer, there is an ideal to become an architect. So, in peacetime work, but also actively to see a variety of books, see the Garden inside the fine article. Hope, in this pursuit of the dream of the road, can leave little bit, also is a kind of consolidation of knowledge, some share.Reading experience Soon after work, I read the fi

evolved from primitive mollusks, the earth experienced an evolutionary explosion that produced and perished at an unprecedented rate. "Unusually dangerous," Bezos concludes, "is not evolving." 」"Evolution" is not just a theory for Amazon, but a blend of tissue blood. Since July 1995, the advent of a "single cell" online bookseller, Amazon has grown into a giant online mall in its 14-year history, offering millions of goods and gaining more than $34 b

message middleware to solvePhase nine, the introduction of message middlewareAs the site continues to evolve, sub-modules that are developed in different languages and subsystems deployed on different platforms may appear in our systems. At this point we need a platform to pass reliable, platform-and language-independent data, and can be load-balanced transparent, can be called in the process of collecting call data and analysis, speculate on the site's access rate and so on a series of needs,

Chief Technical Officer of--ncrteradata Division StephenbrobstJoerarey, chief consultant, strategic technology and systems company The most successful data warehouses are progressively developed in a gradual manner, each of which improves the business value of information. In recent years, data warehousing has evolved to support enterprise decisions and even new heights for enterprise partners and customers.Previously, data warehouses provided strategic decision-making capabilities in certain ar

Applications are always the driving force behind technological development. In the face of increasingly complex business applications, the technical architecture of network devices has become a key factor in the scope of application of devices. Different application environments require different network devices. For example, the application of NGN needs devices based on the SoftSwitch technical architecture, for example, the vertical network needs to focus on routers, and the campus network foc

Messaging capabilities are an important support for the internet of Things (Ofthings, IoT), and many of the IoT technologies are rooted in the mobile internet. This paper describes the application and evolution of mobile Internet message push technology in IoT.I. IoT architecture and KEY technologiesFrom the perspective of development, wireless access is the core technology of IoT devices, identity device management and message push technology are the

ObjectiveIn C # we can customize delegates, but why does C # have to have generic delegates built into them? Because we often want to use a delegate, if the system built up some of the delegates you might use, then omit the definition of the delegate, and then instantiate the delegate step, so that the code looks concise and clean and can improve the programmer's development speed, he le! This article allows you to review the extension methods, as well as to understand the implementation of the

management technologies. This information, as master data, varies depending on the industry and organization. The technology itself can be used as a middleware, providing a platform for the system to find the approved data definition. For master data management to perform its functions better, it must be driven by a close working relationship between business and it. MDM Transactions and analytics applications SOA applications with three facets Metadata-driven architecture Cloud computing

Software evolution is the software maintenance and upgrade during the application period, this chapter mainly discusses the characteristics of software evolution, software maintenance and software re-engineering.Software evolution features include software maintenance is inevitable, software changes will lead to software degradation, in the early development of t

Everything is fine, but if you consider cross-platform and language, you ca

In Linux, we can do a lot of things. The beautiful interface also makes us forget the beautiful and silver-wasting world that Windows advocates for a while. However, in Linux, we always feel that different from Windows makes it hard for us to understand many simple things. This is also quite normal, because the environment is different, we will be overwhelmed within a certain period of time. On Windows, we can use outlook to complete mail tasks. However, many people do not know how to use this

on the evolution process of Web site architectureObjectiveLet's take javaweb as an example to build a simple e-commerce system to see how this system can evolve step-by-step.Features of the system: User module: User registration and management Commodity modules: Product display and management Trading modules: Creating Transactions and managing Stage one, single-machine building web siteAt the beginning of the site, we often run a

SSL type of Bio ---According to OpenSSL doc\crypto\bio_f_ssl.pod translation and his own understanding written (Author: dragonking, Mail:wzhah@263.net, posted in: http://openssl.126.com OpenSSL Professional Forum) As you can see from the name, this is a very important bio type that encapsulates the SSL rules in OpenSSL. and functions, equivalent to providing a good tool for using

At present, China's core switches are developing very rapidly, while also promoting the continuous improvement and Stability of core switches. Below we mainly analyze the evolution of the core switch architecture and the principles of various architectures. Applications are always the driving force behind technological development. In the face of increasingly complex business applications, the technical architecture of network devices has become a key

The core switch is still quite common. So I studied the Architecture Evolution of the core switch and shared it with you here. I hope it will be useful to you. Applications are always the driving force behind technological development. In the face of increasingly complex business applications, the technical architecture of network devices has become a key factor in the scope of application of devices. Different application environments require differe

the front and back end provide the infinite possibility of decoupling. But if we think that the use of NODEJS technology is to achieve the separation of the front and back, this understanding is too superficial, I will talk about my research on the front-end separation technology, and these technical solutions hidden behind thinking, I hope these thinking can give you a new way to understand the front-end separation technology.We have a deep understanding of the front-end separation technology
