occurrence of dirty reading. 03:repeatable read (can be re-Repeat): can avoid dirty read, non-repeatable reading occurs. 04:serializable (serialization): Avoid dirty reading, non-repeatable reading, the occurrence of phantom reading. Note: Four isolation levels highest: seralizable level, the lowest is the read uncommitted level; The higher the level, the lower the execution efficiency; The isolation level setting is only valid for the current link, and for the JDBC Operations database, a Conne

Introduction: The impression that programmers give many people is generally not good at communication, serious expressions, close thinking, serious work, calm and so on. Are these features related to program development? What problems will people with different personalities face in team development and what roles will they play in team development? Program Development is a kind of social behavior of people (development cannot be separated from society or applications). The management of program

(for example, 3*3 cell/block), the characteristics of all cells within a block descriptor concatenated together to get the hog characteristics of the block descriptor. 7) Descriptor The Hog feature of all blocks in image images in series to get the Hog feature descriptor of that image (the target you want to detect). This is the final feature vector that can be used for classification. the detailed proc

(Refer to the analysis content of csdn Bo main cy513) First, describe how humans recognize objects: How humans recognize an object, of course, to have a concept of what is in front of this object, the human life has begun by visual acquisition of all things in the world information, including an object shape, color, composition, and through learning to recognize the object of other information such as physical, chemical characteristics, Such informa

The whole C + + programming is done around the object-oriented way, the inheritance of the class is a very very important mechanism of C + +, the inheritance attribute can make a new class get the operation and data structure of its parent class, the programmer just adds the component in the new class that is not in the original class. It can be said that the content of this chapter is the key to C + + object-oriented programming. Let's briefly say the concept of inheritance, first look at the

In the early days of web design , we will first collect the expectations of the design direction, we often collect such suggestions: Product Manager: To be easy to use, conciseDesign Director: To feature, to highlightDepartment Manager: to the atmosphere, to unify...... The designer wants to three heads, both ways, gu this and Guppelt. First of all, for the site, vision and experience is one, complement and win together. Visual unity requires experience consistency, and experience innovatio

The examples in the book are relatively easy to understand, but because it is written by foreigners, the habit of example is not very Chinese characteristics, may occasionally look awkward, there are language habits are not Chinese wind. 　　Of course, after reading this book, you will be able to understand exactly what design patterns can solve for you, and what problems cannot be solved for you (such as not replacing your code). I've changed some of t

Lecture Video: What makes a good Feature? -Machine learning Recipes #3Https://www.youtube.com/watch?v=N9fDIAflCMYA classifier can have good performance only if you use a good feature. Providing or identifying good feature is one of the most important tasks when using machine learning.Suppose you want to classify a dog's category to distinguish between Greyhound and Labrador.We consider two characteristics, height (inches) and eye color.Here we assume

It's been a while since I've been learning about iOS for the language of shallow thinking oc. Today took a little time to think about the language characteristics of OC, let their heart not so impetuous, pay attention to the foundation, return to the source. OC as an object-oriented language, nature has object-oriented language characteristics, such as encapsulation, inheritance, polymorphism. He has the

confused. Other languages that have closure characteristics, which can easily invoke closures and have elegant syntax at the same time. In the example above, using a traditional loop in Scala can work, but do you write that? On the other side, it is said that the above topic can also be implemented using a PHP closure, but would you normally write this? It is certain that a PHP closure can be a sharp saber in some cases (such as deferred execution

Basic principle and characteristics of Crystal Oscillator Generally, the crystal oscillator uses the capacitor three-end (kobiz) AC equivalent oscillator circuit of 1A. The actual crystal oscillator exchange equivalent circuit 1B, where CV is used to adjust the oscillation frequency, generally, it is implemented by using a variable-capacity diode with different reverse voltage, which is also the mechanism of voltage control. The equivalent circuit of
