the quantitative part of the encoder according to the subjective quality standard, the encoder tries its best to save the bit rate while achieving this quality standard. The key lies in the Evaluation Method of the encoder's subjective quality. This is a combination of CQ and VBR. It can also be viewed as automatic.One of the optional values of MVBR weilong Chinese Edition 5 is "filling data without damaging the minimum bit rate". In my opinion, if t

After completing the deployment of map data, you can develop the TileSource Url ing algorithm based on the self-deployed map data, then, you can load and present your deployed map data in the same way as loading Google online map data. Modify the algorithm used to load online map data so that it can adapt to loading Google Maps data deployed by itself.

Index Tuning Recommendations1. Calculation of indexed columnsFor example, we want to find the age and name in a data record with ID greater than 100 in the table Tb_test.
The correct SQL statement is:
Select Age,name from tb_test where ID > 1*100;
The SQL statements that are not recommended are:
Select Age,name from Tb_test where id/100 > 1;
2. Concatenation of indexed columnsFor example, we want to find the IDs and age in the records in table tb_test with name
Thank you for your enthusiastic reply. Sorry, I didn't make it clear when I described the problem, which delayed your time. For example, the word "Chongqing", because the word "heavy" is a multi-tone word, reads: C, Z; and "Qing: Q should combine all the pronunciations: CQ, ZQ, "...

reasons. First, you need a queue to save the job. It also needs to be used to track the data structure of terminated threads. In the previous articles (see references at the end of this Article), I have mentioned thatPthread_join? The use of "Clear queue" (called "CQ") can solve the problem of waiting for any terminated threads (this issue will be discussed in detail later ). The following is the standard queue code. Save this code to the files queue

Summer Training Summary
When I joined boblee and yyd during the summer training session last year, I was the only one who trained at the base to review my postgraduate entrance exams and then joined YJ and CQ this year, three people can perform problem training at the base. I think about myself as a newbie last summer, and I can only hold the thigh of two teammates. This year, as a member of a team,
true, not afraid of no opportunity, afraid of not prepared, not to improve their own always think of some have not. Writing simple things can still play the flowers. Do not touch advanced things must be their level is not enough, and not other, otherwise knowledge is always more and more wide. In school know what may be learned in school to the community but there is no soft use, can society really need it? In the company found that the direction of demand is the direction of their own developm

Working Group
I will demonstrate how to create a multi-threaded workgroup. In this solution, we have created many worker threads. Each thread checks wq ("work queue") to check whether there is any work to be done. If there is work to be completed, the thread will remove a node from the queue, execute the specific work, and then wait for the new work to arrive.
At the same time, the main thread is responsible for creating

classified, the high-priority communication (CoS = 4-7) can be sent to the acceleration (high-priority) queue, while the low-priority communication (CoS = 0-3) is sent to the common queue. This scheduling is essentially a priority queue algorithm. Generally, a layer-3 LAN switch is used for LAN core. For example, the Catalyst 6500 series provides additional QoS features for priority voice communication and supports IP priority classification, you can also provide multiple queues for each interf
