============= optimization of large-scale website Architecture =====================A small website, such as personal website, can use the simplest HTML static page to achieve, with some pictures to achieve beautification effect, all the pages are stored in a directory, such a site on the system architecture, performance requirements are very simple, with the Internet business is constantly enriched, Website related technology After these years of dev
Database scale and capacity planning includes estimation of system resources required to meet enterprise-level business objectives. Good capacity planning not only focuses on meeting current needs, but also adjusts the system size for future needs, so that the database infrastructure can be seamlessly expanded based on changes in business needs. In addition, a good plan will take into account workload changes

In the Word2013 document window, users can set the display scale of the document page as needed to more flexibly view page effects. Users can set the WORD2013 document page display scale in two ways.
Method 1: Use the Zoom dialog box
Users can set the page display scale in the Zoom dialog box, as described in the following steps:
Step 1th, open the Word2013 do
Recently, the problem of mesoscale estimation in visual tracking has been solved by combining scale space theory.
First post a scale space blog: Click to open the link
Then there are several methods based on the scale of the mean_shift, although now Mean_shift has no OVA.
Paper 1:
Mean-shift Blob Tracking through scale
Today I have studied scale and resolution in openlayers and learned something I didn't know before.I. First, I will clarify several concepts: 1. Scale: Scale, ratio of distance on the graph to distance on the field. 2. Resolution: resolution. Each pixel represents the field distance (MAP units per pixels ). 3. Extent: MAP range (four ). 4. zoomlevel: zoomlevel (0
An important quality of a leader is the direction and pace. Its level is suitable for gray scale. A clear direction is generated in chaos. It stands out from the gray, and the direction changes with time and space. It often becomes unclear. Neither white nor black nor either

Uigesturerecognizer class
This class has a series of subclasses, each of which is used to identify a specific type of gesture. They are:
Uitapgesturerecognizer-Click the gesture. It can be configured as "click" or "combo" recognition.
Uipinchgesturerecognizer-"Kneading" gesture. This gesture is usually used to scale a view or change the size of a visual component.
Uipangesturerecognizer-"Pan" gesture. Recognize drag and drop or move actions.

Develop a Winsock application with a large response scale using the completed Port
It is not easy to develop network applications. However, you only need to master several key principles --
Create and connect a socket, try to connect, and then send and receive data. What is really difficult is to write a program that can accept less than one and more
Thousands of connected network applications. This article will discuss how to use Winsock2 in Windows
able to use the base class object. For example: I like animals, I must like dogs, because dogs are the children of animals, but I like dogs, can not be concluded that I like animals, because I do not like mice, although it is also an animal.For example, there are two classes, one class is BaseClass, the other is the subclass class, and the subclass class is a subclass of the BaseClass class, so if a method can accept a base class object base of BaseClass type, such as: Method1 ( Base), then it
Ggplot2 Scale Related SettingsScale settings: Mainly used to adjust settings for each layer after Ggplot drawing.1. Related attribute scale settingIncludes Scale_size (), Scale_alpha (), Scale_shape ()As you can see from the name above, these three settings are primarily related to the Ggplot layer properties, including size, transparency, and shape.The main parameters for this setting are listed below:SCAL
file. The disadvantage is that when many files need to be updated, each column of the file needs to be written to the database separately. The most common solution is to use a similar log structure merge (LSM) method for bulk write operations. Many column-type databases improve read performance by adding a complete sequence to the table.Splitting data through columns can greatly reduce the amount of data read from the hard disk, as long as the query operation is in a subset of all the columns.I

Agile features are better suited for small projects and smaller teams, but as agile is used by more and more companies, agile is moving into large-scale organizations and starting to serve large projects, thanks to the support of agile at scale and other related theories. A recent Forrester survey shows that large-scale agile is maturing, but there are still many
This is the Oracle Coherence 3.5 book, Chapter One: Achieving performance, Scalability, and availability Objectives, section II: Achieving Scalability, the database extends the part of the reading notes.Traditional relational databases are difficult to scale, usually vertically scaled, but scale horizontally only when they reach a certain level.The scale-out of t
, Software Configuration Management does not play a significant role, but for large-scale software development, Software Configuration Management is crucial because of the large number of developers, large programs, and complex systems.Software Configuration Management is so important for software development management. Its main idea and content lies in version control. Version control is one of the core ideas of Software Configuration Management. It
Estimation of the scale of software projects has always been complicated because of the complexity of the software, the lack of historical experience, the lack of estimation tools, and some human errors, the estimation of the scale of software projects is often far from the actual situation. Therefore, estimation errors have been listed as one of the four major causes of software project failure.
