First of all, a happy mid-Autumn Festival, in this week's training, another contact with Ajax, the last time on the AJAX study is not very thorough, but after two or three weeks after another contact, feeling a lot of clarity of mind;Ajax (Asynchronous Javascript + XML) Asynchronous refresh has an unparalleled role to play in satisfying the needs of users, and it is always necessary for us to do some of the necessary steps before writing AJAX operations:ajax--core XMLHttpRequest objects, and jqu

I'm still messing with the technology. In the past few years have also done something else, finally discovered or technical work their favorite (in fact, make other also very failure, not to be the boss to open should thank goodness). If there is a job that makes me want to sleep, I get up in the middle of the night and write something, only write the code. Since you like, but also to the company to make money (the company can also pay me), or continue to do it. People should do what they are go

However, it is necessary to clarify and understand the basic principles of Mog, and to sort out the realization of OPENCV, so that thor

SVM is a classic classification algorithm, the network has a lot of wonderful blog and books to explain, today I put together these materials, thanks to the share of Daniel![1] Jerrylead's blog, the author gives a fluent and popular derivation according to Stanford's handouts: the SVM series.[2] Carlsberg's introductory series of SVM speaks very well.[3] Pluskid's support vector machine series, very good. The derivation of the dual problem is very good.[4] Leo Zhang's SVM Learning series, which

JS simple console plug-in [For blogs and forums to run js]I wrote this item last year, but the level was not very good at the time, but I still implemented simple functions. Let me briefly introduce how to use this item. This is because when I write something in a forum or blog, I very much want to have a running function. Of course, most of the functions are implemented open. And there is no console for debugging in the IE6-7, so the brain was writin

1. In Java programming, multithreading concurrency is always somewhat confusing: why is concurrency generated? What is the impact of concurrency? What technologies (mechanisms) are available to handle concurrency in JavaI looked up some information about the causes of concurrency. There are two reasons for this: first, there is a shared resource and there is a modification to the resource (static variable), and there is a state variable in the object and the object is used incorrectly in multi-t
