backlog refinement

Scrum has three ceremonies: Sprint planning meetings, sprint review meetings, and scrum daily meetings Sprint Planning Meeting (sprint planning meeting) Prepare for the start of the sprint based on the product or project plan developed by the product owner. The product owner can be a customer or customer representative or agent. For product companies, the customer is the market, and the product owner plays the role of market agent. A product owner needs a vision to determine the final goal of t

Client side: Call SOCKET socket = new socket (remoteaddress, 1287), client side will bind the client's PID to a random unused port ; Call SOCKET socket = new socket (remoteaddress, 1287, localaddress, 1288), client side will bind the client's PID to the sp

The sixth chapter Agile processRead the sixth chapter to understand what an agile process is. "Agile Process" is a collection of values and methodologies in the context of software engineering. Agile is a thought, or a value, that covers several methodologies for software development.The approximate process is as follows:1. Step one: Find out what needs to be done-product Backlog.2. Step two: Determine what the current sprint needs to resolve--sprint

designs the entire product as a product backlog. Product backlog is a list of requirements. (BacklogIt can be understood as a requirement or something to do)2. Hold a product backlog plan meeting, estimate the time of each backlog, and determine which backlogs need to be completed in the first sprint, that is, the

IceScrum is an Open Source tool (under GPL). Now lastest IceScrum 2 version R2 #15.1 is Released.Introduction IceScrum is an J2EE application for using Scrum while keeping the spirit of a collaborative workspace. It also offers virtual boards with post-its for sprint backlog, product backlog and others. The tool offers everything that is in Scrum: The role management: Product Owner, ScrumMaster, Team mem

: the analysis above seems to require the smaller the paragraph, the better, but because we need to save the code table to decompress the huffman compression result, each section must have a different code table, so the section is too small to save the code table. In this way, it seems that the section should be as large as possible, so that the number of saved parts of the code table should be as small as possible.Gzip adopts this policy to determine the section size: lz77 compresses every 4 k

extreme programming, scrum, feature drivenDevelopment and crystal etc. Scrum was raised by hirotaka Takeuchi and ikujiro nonaka in 1986. The skeleton is shown in Figure 1. Figure 1 The lower circle represents an iteration of development activities thatOccur one after another. In scrum, it was called sprint. Each sprint isAn iteration of 30 consecutive calendar days. The output of each SprintIs an increment of product. The upper circle represents the dailyInspection that occurs during the sprint

offset of the slave server (2) Master Server replication backlog Buffer (3) server running ID 3.1.1 copy offset Both the master and slave servers maintain a replication offset: Each time the master server sends a n-byte command to the slave server, it adds n At its own copy offset. Each time the server receives n bytes of data, it adds n At its own copy offset. For example, if the current offset of the master-slave server is 100 and the master-sl

messages and no new packages are coming. The table is not fine. Figure 1 below: In the figure above, there are 13 steps, the application process uses a blocking socket, the flag flag bit is 0 when the Recv method is called, and the user process does not have process sleep when it reads the socket. The kernel uses 4 queue containers when processing received TCP messages (when the list is understood), receive, Out_of_order, Prequeue, and backlog queues

The behavior of the backlog argument on TCP sockets changed with Linux 2.2. Now it specifies the queue length for completely established sockets waiting to be accepted, instead of the number of incomplete connection requests. The maximum length of the queue for incomplete sockets can be set using /proc/sys/net/ipv4/tcp_max_syn_backlog. When syncookies are enabled there is no logical maximum length and this setting is ignored. See tcp(7) for more infor
