Use DDD + GDB to develop ARM Linux programsToday, we have made some progress. Please write it down to avoid forgetting it.Since Linux runs on my board, I have been thinking about how to debug future programs. In fact, I am really a layman in Linux development. Today I know what GDB is. I believe that many people have been using LED and printf methods for debugging since bootloader debugging. When I complete the setup, I will plot a user partition in m

In actual projects, we may face different needs at any time. The elements of different aspects determine the development mode we adopt. For example, how complicated is it? Are all requirements clear enough? Do developers have sufficient knowledge about related services? Is the project construction period reasonable? All kinds of problems. This also determines that we may need to adopt different development modes to meet different needs. Here are some examples. 1. TDD TDD refers to test drive de

Queuing support, and support for cutting-side programming and other functions. Now that the business functions are almost complete, let's take a look at the implementation of the delivery operation.First, the Sales Order Management home page, where you can see all the user's order status. The specific effect is as follows:Click on the Shipping button to complete the product shipment operation, the user who created the order will receive an e-mail not

DDD domain-driven design: Infrastructure Layer What is a domain service? In the DDD book, some classes or methods are not good for Entity A, and it is not good for entity B, because

There are many ways to install the DDD method: Method One: Use RPM to install package (convenient to recommend) 1) direct to the corresponding URL download rpm installation package ddd-3.3.12-5.fc12.i686.rpm (Address: http://mirror.cse.iitk.ac.in/fedora-archive/fedora/linux/releases/14/Everything/i386/os/Packages/) 2 upload the corresponding installation package to the Fedora System (exp:/usr/local), and t

Overview:If the design is flawed at the architectural level, the solution is either farfetched or incomprehensible. It is difficult for a solution to apply DDD if it is built with a solution that relies on the inability to match the schema diagram and introduces too many dependencies. Architecture is a high-level design, if the design and understanding is wrong, will inevitably bring a variety of problems in the implementation. The architecture is the

Preface: The code that has been building the project structure before, a bit off our topic (DDD), this article we continue to talk about another important point of knowledge in DDD: Domain Services. About the use of Domain Services, the book is also more obscure, in this regard according to the blogger's own understanding of the use of this knowledge point.A preliminary study of

For specific needs, please see the previous blog: DDD Domain driven design practice of how to extract the model, the following is a specific entity, aggregation, value object code, do not want to say what is the entity, aggregation and other concepts, believe that the theory of things we have known. I am curious about ddd, not in real project practice, and even did not see the real

The concept of domain-driven design (DDD) originates from the book published by 2004 famous modeling expert Eric Evans: "Domain-driven design–tackling complexity in the Heart of Software" (Chinese translation: domain-driven design-the core complexity of software solutions), Chi Jianqiang in an article published in 2011, "Domain-driven design and practice", which describes DDD: The domain-driven design is i

Today, I carefully read a friend in the garden's article titled "A ray of sunshine: DDD (domain-driven design) how to focus on domain model (domain model) to deal with specific business scenarios." (Http://www.cnblogs.com/xishuai/p/3800656.html) this blog, I think this is an analysis of the summary of the nature of the DDD article, write well, But the strange thing is that no one reply, it may be because th

class , advanced developers can master the technical points I have mentioned above, although there are some discomfort in development, but they are also overcome as much as possible.Wait, the above mentioned the addition of this base class, the development caused a discomfort, which aroused my thinking, the following to talk about the intuitive what is the discomfort and solutions. 2.1 No physical deletions, only tombstone The real delete operation no longer occurs, and the physical deletion op

I was fortunate to have read many great gods on the realization of DDD, such as the landing of articles, learning more, benefited, in this recommendation: Www.cnblogs.com/hafiz/p/9388334.html78909897Www.cnblogs.com/netfocus/archive/2011/10/10/2204949.html6681253 The following reference to the structure of the official DDD, summed up the relevant experience of predecessors, and then based on their own micro-

Preface: There is almost half a month did not write something, feel so very sorry myself. Today, I read a blog post that reads: The more busy man, the more time they have to write blogs. Oh, seems a bit reasonable, Bo Master in order to prove himself is also busy man, this does not come to learn under the DDD so a sound tall on things. The previous introduction of the next MEF and AOP related knowledge, after the plan to share AutoMapper, warehousing

In fact, the infrastructure layer here is just some interface and base class of the domain layer, there are no other code such as day tools, just to illustrate some basic problems of the domain layer 1, the domain event simple implementation code, all comes to the asp.net design pattern book code Namespace DDD. Infrastructure.Domain.Events {public interface idomainevent { } } Namespace DDD.

follows: Last part: Thinking change Finally, we compare with traditional programming ideas:The first step in traditional thinking is to consider the data, separate the data from the behavior, and then model the data into a database table structure schema, which is actually the turbo Pascal of the enterprise.So the question is: what is the first consideration?The first thing to consider is the language language, which is the unified language, which u

This article is the second part of the implementation of the DDD framework, mainly introduces the realization of the application layer of DDD, and explains the service and assemble responsibilities and implementation in detail. A github address is attached at the end of this article. Compared to the shipping system example in the original book of domain-driven design, the business scenario for social servic

Google provides eclipse and plug-ins for Android Application development as development tools. Based on Eclipse, you can easily debug the APK. (For example, opencore Development) does not provide similar intuitive development tools and debugging methods. This article describes a debugging method based on DDD + gdbserver. Opencore C-level program debugging. The procedure is as follows: open a shell ADB Shell PS view mediaserver process number Gdbserver
