thread goes to sleep, it enters the blocking state (whether or not the cpu is idle or not, it will still be paused, which is mandatory). When the sleep time ends, the system enters the ready state. You need to compete again to seize the cpu permission, instead of immediately executing the method after sleep. Therefore, the actual interval is greater than or equal to the sleep time. The java Thread class provides two static methods to pause a Thread. 1 static void sleep(long millis)

as hardware raid, and features are not as good as hardware raid. Next we will introduce various RAID technologies I. RAID 0 The band technology is used to write data in parallel on multiple disks in bytes or bits (the starting offset of each disk is the same, and the subsequent segments of a certain number of bytes, i/O read/write performance can be improved, but it does not have data redundancy like raid1. Once the hard disk fails, it will be done. The structure is as follows. Ii. Raid 1 The

client, name/value pairs are a good choice because server and server-side languages can easily interpret name/value pairs, as well as using XML when returning data to a client. There are several ways to get the XML response from the server and use the more standard code to extract the data, which is used in the client.Listing 1. Server response (XML format)----to treat XML as plain textThe simplest choice for working with XML (at least in terms of learning new programming techniques) is to hand

Determine the compression format based on the application's actual situation. Personally, is it more likely to use the fastest compression speed or the best space compress

architecture and Activity, and the lifecycle of an application ). I believe I can handle this.However, if you want to develop a lower-layer architecture, such as embedded development (Android driver development), you need to know more about it. After all, Arm + Android is very promising this year. you need to understand Linux, Arm, C, C ++ and other knowledge. After all, this requirement is quite high. you

Xception: Here we have a picture of a Scottish barrel, especially my favorite Scotch whisky, Lagavulin. Xception correctly classifies this image as "buckets".The last example is to classify using VGG16: A few months ago, when I finished the game of the Wild Hunt, I took this photo of the monitor. VGG16 's first prediction was "home theater", which was a reasonable prediction because there was a "TV/monitor" in the top-5 forecast.As you can see from the examples in this article, the

. Thanks to Juanny's document, it is very helpful to understand the element values in x264_scan8. This is mainly an intermediate addressing matrix, it allows you to conveniently find the color and brightness of MB in the corresponding cache and zero_count.Scan8 [] is actually the scanning sequence and storage location of 4x4 blocks. You can see the function of scan8 in the 8x8 matrix. t indicates the block on the current block, L indicates the Left Bloc

project (following the same package naming rules as java programming ). Your package name must be unique among all the package names in the Android system. Therefore, you 'd better choose to use the Reverse Domain Name of your organization or publisher as the package name. In this project, you can use a package name similar to "com. example. myfirstapp. However, you cannot publish an application with the package name starting with "com. example" on

3 native graphics engine implementation Native graphics engine graphics drivers have provided framebuffer-based Drivers Based on Linux kernel. Currently, they support linear 2 bpp, 4bpp, 8bpp, and 16bpp display modes. As we have seen above, most of the interface functions provided by gal are related to graphics. They Call graphics drivers to complete tasks. The graphic driver shields the details of the underlying driver and completes the underlying Dr

mind map is roughly divided into two categories: one is the integration of thinking , such as the production of reading notes, work plans, personal resumes, meeting records, activities, etc., the other is the discrete thinking (generally involves thinking discrete situation is not too much), such as literary creation, Creative work, such as pre-activity planning, imagination and associative ability, is biased towards some non-specific thinking exercises.If you differentiate from specific work s
