the most bandwidth in the intranet. (Figure 1) 2. Who is downloading BT? Requirements: BT downloading is an enemy of slow lan network speed. If someone uses BT downloading in the LAN, the speed will be slow. We often say that Bt is essentially a point-to-point communication, using the BitTorrent protocol. During BT download, the two "handshakes" of the BT peer protocol must be passed ". If someone uses BT to download files in the Intranet, it will occupy a lot of network resources, maki

I graduate design is to do an Android-based mobile Office system, I work with classmates, responsible for some of the functions of the Code implementation and interface design, login registration, to do reminders and schedule management.From the design of the various functional modules to the implementation, although the basic functional requirements of the original subject, but there are many shortcomings, some features of the bug has not been resolved, some functions need to be optimized, the

The book has used cliffs to describe software boundaries: if you can walk confidently and safely on the edge of a cliff without falling down, the flat will almost never be a cinch. Boundary conditions are special cases, because programming is fundamentally about creating problems on the boundary. The practice shows that faults often appear on the boundary of domain or range of definition.1. The concept of the boundary value

What is the R language? R language, a free software programming language and operating environment, mainly used for statistical analysis, mapping, data mining. R was originally developed by Ross Ihaka and Robert Jes (also known as R) from Oakland University in New Zealand and is now developed by the R Development core

) Presto:facebook in November 2013, Presto, a distributed SQL query engine, was designed to specialize in high-speed, real-time data analysis. It supports standard ANSI SQL, including complex queries, aggregations (aggregation), connection (join), and Windowing Functions (window functions). Presto designed a simple abstraction layer of data storage that can be qu

The characteristic analysis of C/s structure and b/s structure In order to distinguish from the traditional C/s mode, it is specifically called B/s mode. Recognizing the characteristics of these structures is critical to the selection of the system. 1, the performance of the system In the performance of the system, B/s has the advantage of its remote browsing and information acquisition flexibility. Any time, any place, any system, as long

function according to the product functional requirements and design instructions, test engineers must design and execute test cases based on product functional requirements and test plans, and also refer to the product design instructions. Therefore, the purpose of the test plan is: determine what to test, how to test, and what quality standards to meet. How to generate effective test solutions?If you just copy the product requirements and some design instructions and give a test progress plan

based on defined performance objectives to determine whether the system meets performance requirements, at the same time, you can analyze the System Bottleneck Based on the stress test results, and then perform corresponding optimization. There are still a lot of tools that can be used for stress testing, such as LoadRunner and jmeter, however, the stress testing topic is too big. I will not talk about it here, but I don't know much about it. Analyze System performance bottlenecks Based on th

Software development is a complex system engineering that involves various factors. In actual work, various problems may often occur, or even failures. How to summarize and analyze the causes of failure and draw useful lessons is the key to a company's success in future projects.The requirement content is unclear and cannot be fully grasped. This is a problem we often encounter. On the one hand, due to the lack of IT knowledge of the customer (demand

associating the model with variables of interest has only recently arisen. Data such as this is usually handled by the generalized estimation equation (general estimating equations, GEE), but the GEE method is progressive and assumes a wide range of samples. I want a generalized linear model with beta-two R. An updated R pack estimates the model: Ben Bolker wrote the Betabinom. and SPSS didn't. Integrated document Publishing. R seamlessly integrates

Four ways to back up your database: L Full Backup: Creates a copy of the data that exists in the database when the backup is complete. differential backup: Records only data that has changed since the last database backup. Differential database backups are smaller than database backups, and backups are faster, so you can back up more often, and regular backups reduce the risk of losing
