Exercise: Add a button next to each item in the cart, click Minus One, and the quantity is 0 to delete the item. Use the usual method to use AJAX support first.1. Custom method Decrease, set the path routes.rb for it. put ' decrease ' in Resouurces:line_items's block, on:: Member2. Define this method in the controller.
Attention?? : You need to declare the instance variable @cart in action because you want to use render @cart render the front page sidebar. Here are the methods in the prev
to return for a second time, and then an exception will occur.
To resolve this situation, we can lock the interface when there is a network request and not allow the user to do more (the better way is to just lock some buttons rather than the entire interface.) But here's an example of locking the entire interface. Our solution is simple: When Qnetworkaccessmanager makes a request, we enter a new event loop that blocks the operation. Our code example is as follows:

Tags: code image send delay bandwidth technology pre class sendWithout assembly, the number of threads is simplified to a direct while loop recv, setsockopt so_sndbuf, So_rcvbuf set to 256*1024, the test result in a short time is 6.7gb/s. But the long test results are as follows: The horizontal axis of the ROS receives the number of event, in 40000 units. (x, Y) indicates that when Ros receives the x*40000 event, the bandwidth of the receiving end is Y gbits/s. Event size is 2KB. As can be seen

Recently I am studying multithreading, the title is derived from the first article of "second kill multithreading" (http://blog.csdn.net/morewindows/article/details/7392749) by Mr MoreWindows)Excerpt:
Question 5 (Google interview)
There are four threads: 1, 2
From the previous introduction, we know that in a binary tree, each node has only one data item, with a maximum of two child nodes. If you allow each node to have more data items and more child nodes, it is a multi-fork tree. This blog we will introduce the--2-3-4 tree, which is a multi-fork tree, with a maximum of four child nodes and three data items per node.1, 2

The 2-3-4 tree is a B-Tree of order 4. It is a self-balancing data structure that can be found, inserted, and deleted in O (LGN) time, where n is the number of elements in the tree. 2-3-4 trees and red black trees are equivalent, that is, each red and black tree can be conve
Chapter 1: a goal
A ship with no sailing targets, the wind in any direction is against the wind
1. Why are you poor? The first point is that you have not set the goal of becoming a rich man.
2. What are your core goals in your life? The fundamental difference between an outstanding person and a mediocre person is not talent or opportunity, but whether there is a goal or not.
3. One step ahead: Success begins with the target
Chapter One: a goal
A ship without a sailing target, wind in any direction is upwind.
1, why you are poor, the 1th is that you have not set a goal to become rich
2. What is your core goal in life? The fundamental difference between a distinguished person and a mediocre is not a gift, an opportunity, but a goal.
3, one step ahead of the start, life ahead of a big step: Success starts from the selected target

the color sample value is determined by the sampling frequency. In the MPEG-2, there are three proportional formats: (OR.

Sl is composed of additional data and a series of macro blocks. Its minimum length is 1 macro block.When the image width, it becomes the largest Macro Block length in the MPEG-2 layer. In order to conceal the err
section starts running, our program will be retrieved from the Rom, it is sent to the openmips processor for execution. Currently, openmips only implements one Ori command, so the test program is very simple, as shown in the following figure. The inst_rom.s file under the CD Code \ Chapter4 \ testasm directory is attached to this book.

by element id, class, and tagName.
1. $ ("# id"): id selector, document. getElementById ("id ");
2. $ ("div"): Element selector document. getElementsByTagName ("div ");
3. $ (". myClass"): class selector, which returns all elements of class = "myClass"
4. $ ("*"): returns all elements, mostly used for context search.
5. $ ("div, span, p. myClass"): A Multi-condition selector that returns all elements found
Section 5 of Matrix
In this section, we will introduce a commonly used method for processing matrices with higher levels, that is, matrix blocks. sometimes, we regard a large matrix as composed of small matrices, just as the matrix is composed of numbers. especially in operations, these small matrices are processed as numbers. this is the so-called matrix block.
To illustrate this method, let's look at an example.
