【Java Tutorials】:并发(Concurrency)——入门
Computer users take it for granted that their systems can do more than one thing at a time. They assume that they can continue to work in a word processor, while other applications download files, manage the print queue, and stream audio. Even a single application is often expected to do more than one thing at a time. For example, that streaming audio application must simultaneously read the digital audio off the network, decompress it, manage playback, and update its display. Even the word processor should always be ready to respond to keyboard and mouse events, no matter how busy it is reformatting text or updating the display. Software that can do such things is known as concurrent software.

【知识图谱】:科普——万维网、语义网、知识图谱、RDF、RDFS、OWL、SPARQL、RDB2RDF、D2RQ、Protege
通过RDF(S)可以表达一些简单的语义,但在更复杂的场景下,RDF(S)语义表达能力显得太弱,还缺少诸多常用的特征。包括对局部值域的属性定义,类、属性、个体的等价性,不相交类的定义,基数约束,关于属性特征的描述等。因此W3C提出了OWL语言扩展RDF(S),作为语义网上表示本体的推荐语言。

【Fiber】: [转]React 为什么使用链表遍历 Fiber 树
To educate myself and the community, I spend a lot of time reverse-engineering web technologies and writing about my findings. In the last year, I’ve focused mostly on Angular sources which resulted in the biggest Angular publication on the web — Angular-In-Depth. Now the time has come to dive deep into React. Change detection has become the main area of my expertise in Angular, and with some patience and a lot of debugging, I hope to soon achieve that level in React.
