Satisfying memory ordering requirements between partial reads and non-snoop accesses

阅读更多关于 Satisfying memory ordering requirements between partial reads and non-snoop accesses

A method and apparatus for preserving memory ordering in a cache coherent link based interconnect in light of partial and non-coherent memory accesses is herein described. In one embodiment, partial memory accesses, such as a partial read, is implemented utilizing a Read Invalidate and/or Snoop Invalidate message. When a peer node receives a Snoop Invalidate message referencing data from a requesting node, the peer node is to invalidate a cache line associated with the data and is not to directly forward the data to the requesting node. In one embodiment, when the peer node holds the

Typical uml diagram for showing events

阅读更多关于 Typical uml diagram for showing events

问题 I have a couple modules. They communicate to each other through events. What UML diagram would typically be used to show this? Is there a non uml diagram people use? Any examples? 回答1: I think you definitely want a sequence diagram to show all the event interaction between modules in sequence. This is the preferred way to represent sequence of asynchronous messages between components 回答2: If you want to express the fact that a module A fires an event E that is handled by module B, I suggest a

In C++ how to best decouple 2 classes that must maintain collections of references to each other

阅读更多关于 In C++ how to best decouple 2 classes that must maintain collections of references to each other

问题 I am looking for advice on the most elegant and secure way to decouple two C++ classes that maintain collections of pointers to each other's types. I implemented it recently using a common base class for polymorphism and was told that it was an unsatisfactory solution. I am eager to learn other ways this can be achieved. Thanks in advance... I have added a simplified version of the class definitions below. I am aware that the SalesTeam class is not decoupled from SalesPerson here. // Global

Microservice, amqp and service registry / discovery

阅读更多关于 Microservice, amqp and service registry / discovery

问题 I m studying Microservices architecture and I m actually wondering something. I m quite okay with the fact of using (back) service discovery to make request able on REST based microservices. I need to know where's the service (or at least the front of the server cluster) to make requests. So it make sense to be able to discover an ip:port in that case. But I was wondering what could be the aim of using service registry / discovery when dealing with AMQP (based only, without HTTP possible

How to client-side validation and server-side validation in sync?

阅读更多关于 How to client-side validation and server-side validation in sync?

问题 Typically when writing a web-app we want to perform validation on both client side to offer immediate feedback and on server-side to ensure data integrity and security. However, client-side browser apps are typically written in JavaScript. Server-side can be written in Java, Php, Ruby, Python and a host of other languages. When server-side is backed by something like node.js, it is really easy to re-use the same validation code on both client and server, but if server-side is based on Rails

Hidden input fields vs Session Vs Cookie

阅读更多关于 Hidden input fields vs Session Vs Cookie

问题 What are the pros and cons of storing data in: Hidden input fields Cookies/local storage Server side sessions 回答1: Those three are not mutually exclusive things. hidden input A hidden input is just HTML sent to the client. It does not appear on the page to the end-user, but it is entirely accessible to the client. Meaning that the user can see it (just as they can see any HTTP response from your server) by using the View Source feature in their browser. cookie A cookie is just another HTTP
