Author: Wang, JoshI. Basic overview of Kafka1. What is Kafka?The definition of Kafka on the Kafka website is called: adistributed publish-subscribe messaging System. Publish-subscribe is the meaning of publishing and subscribing, so it is accurate to say that Kafka is a message subscription and release system. Initially, Kafka is actually a distributed message queue used by LinkedIn for log processing, and the log data of

such as Ruby and Python had attracted many startups. Until a few years ago, Ruby on Rails was a revolution in WEB development. Many startups have developed innovative products using the RoR and Python Web frameworks. But now interestingly, due to the challenges of performance and scalability, these applications are being rebuilt by other Web technology stacks. Using a dynamic type language in a large application is like drinking a drink with too much sugar. At first, the sweetness of the sugar

forest dimensionality reduction.Indeed, in the age of big data, the more data, the better, seems to have become axioms. Once again, we explained that the performance of the algorithm could lead to less than expected performance when the data data set is too noisy. Removing less or even invalid information can only help us build a more scalable, universal data model. The data model may perform better on the new data set.Recently, we consulted a data analysis team from

established on a large scale.Accurate connection standards are what I think the next generation of mobile internet apps must solve in terms of technical architecture-similar to the REST architecture, to isolate the App status into precise unit pages, and then add a stable address representation. This must be achieved by Apple, Google, and Microsoft platform-level players sitting down to establish unified standards like Web URLs. It makes no sense to play in small circles. Of course, another pos

exactly lightweight, but with only one protocol to support the API, it doesn ' t has a lot of excess bagg Age. I outline some quite subjective reasons why I like this new Web API. From an objective and primitive point of view, the Web API is designed and exists for HTTP. A complex problem with WCF is that it provides everything in every transmission protocol, as Matt Milner in his blog post explains. You have to do some work to apply WCF to HTTP. In contrast, Web APIs are designed to be built

expand and deepen their business. It is not a charge to developers in the early stage. It is a developer's business model that operators need to adapt to, because it is not necessary to try and use APIs. For example, Facebook and LinkedIn are both social networks, but they are driven by different business models. For Facebook, the API business model will help Facebook get users and improve user participation; for

Use Python to master machine learning in four steps and python to master machines in four steps To understand and apply machine learning technology, you need to learn Python or R. Both are programming languages similar to C, Java, and PHP. However, since Python and R are both relatively young and "Far Away" from the CPU, they seem simpler. Compared with R, which is only used to process data, such as machine learning, Statistical algorithms, and beautiful graph analysis data, Pthon is advantageou
