As we know, an true experiment shocould have a treatment group, a control group, a independent variable related to treatment, dependent variable that measures the effect, random assignment, and various requirements to guarantee internal validity. the identification of experiment elements in this study is easy. because the Cause precedes the effect, we can tell that each post is the subject which the treatment works on, the t

In the eyes of many great gods, This is a water problem, but cainiao cannot afford to hurt, and it is not easy to understand English, and it is found that the BFS written for one day yesterday has been relentlessly wrong. ah, it's Valentine's Day yesterday, diaosi is typing on the code. It's still wrong. It cannot hurt... Now let's get down to the point. This is a question of the Minimum Spanning Tree, but the weights between each point are not given every day, we need to use BFs to find out. My

the Slope one recommendation strategy. Back to top of page SummarizeOne of the core ideas of Web2.0 is "collective intelligence", the basic idea of the recommendation strategy based on collaborative filtering is based on the mass behavior, providing individual recommendations for each user, thus enabling users to find the information they need more quickly and accurately.

"physical devices" mentioned here include network card devices, broadband router devices, ADSL dial-up devices, and even power supply devices that provide power to these devices. Generally speaking, the physical equipment performance is good or bad, we simply use the substitution method can solve the problem. For example, when all workstations in a local area network do not have access to the Internet, that this fault should not belong to the individual behavior, but should belong to

pages to the user is valuable, the search engine will give the website a good rank. So how do you do this in the long run? This requires us to regularly add content to the site. Web site content Increase irregular why will be down right? Just imagine, the site content increase irregular can you think this site is not a professional website, no special personnel to manage it? Then search engines will think that the content of such sites will not be of value. 3, two level domain name for unreaso

is also generated document and view two classes, it has been strange why so around the circle. Looking at Swing's design, it's full of MVC traces. It is an art, full of beauty, to study the mechanism of event monitoring, model-view separation, renderer/editor mechanism and pluggable lookandfeel in swing. And if you really hate these designs and think they're weird, it's likely that you've just turned from VB or Delphi, and these rapid development tools have helped you "kill" you.Swing is a good

. This server allows users to search for information in a variety of data sources, including enterprise databases and tables on users' desktops, customers do not need to build a large, single, and well-organized data warehouse, just as users use google search information on the Internet, employees can search all text-based data within the enterprise to obtain useful and relevant information. Mattos says IBM will likely use this feature in WebSphere. IBM is one of several companies that invest i

Hansson has clearly answered 5 reasons why founders should dismiss a workaholic: 14 hours a day of work, in the long run will only lead to exhaustion, the emergence of job burnout, can not improve efficiency. This collapse could have a heavy impact on the operation-and, according to Murphy's law, could cause the greatest damage. The workaholic believes that the way to solve the problem is to keep putting extra time into the problem. These employees are often far less productive tha
