Then, by reviewing the cognitive dimensions of abstraction and the role of abstraction in computing education, we identify three cognitive processes underlying abstraction in computational thinking (e.g., filtering information, locating similarities, and mapping problem structures). We thereby propose a ...

What seems to be lacking is a suitable abstraction for programming pervasive computing environments.───看上去缺少的东西正好适合于编程普及运算环境。 From the previous section, you can see that virtio is an abstraction for a set of common emulated devices in a paravirtualized hypervisor.───从前...
[NSDI12]Resilient Distributed Datasets: A Fault-Tolerant Abstraction for In-Memory Cluster Computing 这篇论文粗略的讲了RDD的设计思路,以及常见的transformation/Action规则和宽窄依赖的基础概念。但是整片文章的视角都是多机并行,对于单机多线程并行并没有提及。 1 Intro 对于MapReduce类的应用,其对于多次计算需要...

12.And it is a timely antidote to oft-repeated abstractions about “cyberspace” or “cloud computing”. 该书也是对被热议“网络空间”或“云计算”这类概念及时说明。 「经济学人-文艺」 13.And these last works, in particular, were seen as a logical jumping-off point for abstraction. 尤其是这...
Resilient Distributed Datasets: A Fault-Tolerant Abstraction for In-Memory Cluster Computing 阅读笔记 提出问题: 数据的重用在很多迭代的机器学习算法和图算法中都很常见,如网页排名、K-means聚类、逻辑回归等。 另一个数据重用的典型场景是交互式数据挖掘,用户在同一数据集上运行多重即席查询。
