sedo parking

After two days of collective training, we have improved a lot in terms of the number of students, and gradually gained confidence in the examination on the 19th. Early in the morning on the 18 th, I first checked the car separation ticket by the examination team and then found the corresponding examination car in the parking lot. The coach asked us to wait at the entrance of the test room. Then he went over. 20 people in the same group gradually r

Objective Recently, our company to do a parking detection system in China, a large city of formal large-scale commercial. As the background service of the system developers, from the first two people, until now only I am a person, looking back on the path of the past few years, filled with emotion. Fortunately, although the original design although the architecture is not very good, but because the focus on performance, so now the service is running

forward a leap, easy to cause rear-end collision. If the car happens to be the first in the queue, it is more likely to hit pedestrians on the sidewalk or bikes with a faster speed.The second situation, in the case of rear-end, the first reaction is to loosen the foot brake, then the car will be further forward, whether the front of the vehicle is stopped or moving pedestrians, are not safe.The third situation, hanging p block solves the first two cases of hidden trouble, but the p block has a

concentrate a large amount of information in the results. For example, if the node A = red is written, A = red is written instead of another name. For the leaf node, You need to display the Action in more detail ), the effect may be as follows: The data of some decision tables can also be organized as decision trees or used to express more suitable data. The decision tree can quickly and effectively associate multiple related rules. The decision logic at each level may be clearly viewed through

waiting for the resource timeout thread. Waiting for monitor entry and in Object.wait (): Monitor is the main tool used in Java to implement mutual exclusion and collaboration between threads, and it can be viewed as an object or class lock. Each object has, and only one monitor. As you can see from Figure 1 below, each monitor can only be owned by one thread at a time, which is "Active thread", while the other threads are "waiting thread", waiting in two queues "Entry set" and "Wait set" respe

products, gaming experience is very critical. If the information with authoritative orthodox characteristics, the QQ space is biased emphasis on the enjoyment of easy pleasure. The experience of desktop gaming, advocates the strategy of setting up operational barriers and game points, creating a sense of user achievement. But in the WAP-side gaming experience, this penalty strategy should be restrained, but it is necessary to use the interactive design to provide a more convenient and quicker e

needs to exchange information with the database server, read the data dynamically from the database and form a "static" Web page to return to the user's browser, and then explain the execution by the browser.Based on the above process of Web page execution, if the "read data from the database" is executed only once and a "static" HTML snippet is inserted, inserting the code into a page that needs to be read dynamically from the database can reduce the cost of accessing the database, thereby inc

Template method ModeDefines the skeleton of an algorithm in an operation, and delays some steps into subclasses. The template method allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm. Popular is that there are a lot of the same steps, in some places there may be some differences suitable for this mode, such as the big talk design mode in the test scenario, everyone's paper is the same, only the answer is not the same. This scenario

be transported bricks the same reason. Corresponding to the action of the Acquirep is Releasep, the M assembly of P to load off, the work is done, the hamster needs to rest, the car also to the parking lot, and then go to sleep. When the Gopher (M) gets its own car (P), it enters the factory and begins to work, which is called the schedule above. The code for simplifying schedule is as follows: Static VoidschedulE (void) {G *gp;gp = Runqget (m->p); i
