Last week was fortunate enough to play Metro's tablet. The visual style, is still my course, but really use but do not feel comfortable, especially when the horizontal browsing content list, the line of sight in the x axis and the y axis switch between, quickly feel dizzy, all this seems more ferocious than waterfall flow. Of course, it's just personal feeling, and I don't want to come to the conclusion that Metro doesn't use it. This translation can roughly represent my position, that is, compared to iOS, Windows this set of things do have a lot of original essence in it, I want to deepen the understanding through this article, ...

This article shows how to setup an active-passive session-aware load balancing cluster (SLBC) consisting of two FortiGate-5000 chassis, four FortiController-5103Bs two in each chassis, and six FortiGate-5001Bs acting as workers, three in each chassis.

"Editor's note" This article is reproduced from the @ zi mu yoyo personal blog. When touch-screen devices, such as smartphones and tablets, become popular, gesture manipulation is becoming more prevalent. This allows the user to directly touch the screen and manipulate the object. Although this is a more natural mode of human-computer interaction, gesture manipulation is still a problem in usability. So we need to design gestures that make it easier for users to understand. Once upon a time, computers could only be used through the command-line interface. If you want your computer to do something, you need to remember all the commands and enter them exactly. When ...

We can often see a variety of robots in science fiction films with human beings in the same stage, and human freedom of communication, and even smarter than humans. People would like to know how such a man-made machine is done, can we really create such a robot now? Joking, I'm not going to be able to explain this right here, but from another point of view it's simple to communicate with the robot. This is through the voice to realize the interaction with the machine, interaction of an operation, human and robot communication, one of its core is the recognition of speech, that is, the robot must first understand the Then this article will talk about Shimonoseki ...

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

If you have never set a root password for MySQL, the server does not require a password when connecting as root. However, it is recommended that you set a password for each account. If you have previously set the root user password, but forgot the password, you can set a new password. The following steps are for the Windows platform. The rest of this section covers the steps for the Unix platform. On Windows platforms, this step is: Log in to the system as an administrator. Stop the MySQL server if it is running. For as ...

Original: http://hadoop.apache.org/core/docs/current/hdfs_design.html Introduction Hadoop Distributed File System (HDFS) is designed to be suitable for running in general hardware (commodity hardware) on the Distributed File system. It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...

Calling the file system (FS) shell command should use the form of Bin/hadoop FS <args>. All of the FS shell commands use the URI path as a parameter. The URI format is Scheme://authority/path. For the HDFs file system, Scheme is HDFS, for the local file system, scheme is file. The scheme and authority parameters are optional, and if unspecified, the default SC specified in the configuration is used ...

"Editor's note" as an operating system, CoreOS uses a highly streamlined system kernel and peripheral customization to implement many of the functions that require complex human operations or Third-party software support at the operating system level, while excluding other software that is not core to the server system, such as GUI and package manager. Linfan, a software engineer from ThoughtWorks, will bring the "Walk Cloud: CoreOS Practice Guide" series to take you through the CoreOS essence and recommended practice. This article is based on the third article: System Services Housekeeper SYS ...

We believe that the goal-oriented design method consists of 4 p, i.e. process, pattern, principles, practices (processes, patterns, principles, practices), and I will discuss the first 3 p. Interaction design is generally a difficult and messy task, and interaction designers are often asked to imagine and define in a tight schedule a possible use of the latest technology, and no one has seen, we must have a deep understanding of the complex areas of products, must balance the competitive priorities, Must understand the constraints of the technology used and the machine ...
