without stopping services, depending on the security and correctness of the upgrade. We believe this can be done. We need to consider the code changes when designing the application and restrict updates to some predefined points. The service speed will not decrease before or after code upgrade.
Dynamic agesIn dynamic languages, DCE is the most common feature. However, to run dynamic languages on static virtual machines, you need to do a lot of work [See for example 33]. Using DCE as a VM mec

discarded, including NO. 0 media packets, 5th media packs, and NO. 0 redundant packets. The receiving FEC is unable to recover because the number of packets received is 8 plus the number of redundant packets received is 1, the total is less than the total number of media packets (10). For the second group, only two media packets are lost and can be recovered normally. The experimental results shown in Figure 5 show that the inference is correct, No. 0 media packets, 5th media packets are lost,

Problem descriptiononce Upon a time, in the mystical continent, there are a frog kingdom, ruled by the oldest frog, the Eld Er. The kingdom consists of N cities, numbered from east to west. The 1-th city, which are located to the east of others, are the capital. Except the capital, links none or several cities to the west, and exactly one city to the east.There is some significant news happening in some cities every day. The Elder wants to know them a
database connection in A1.
A5 = join @ 1 (A2: sales, SellerId; A3: emp, EId)The above code connects A2 and A3 to the left, and the connection field is the SellerId of A2 and the Eld of A3. For the sake of intuition, the two pieces of data after the connection are named sales and emp respectively. Function join performs join calculation. Option @ 1 indicates the left join. The calculation result is shown in the left join:

The Linux kernel uses the Special Data Type atomic_t instead of the integer type that uses the C language directly, which is due to the following reasons:
(1) The atomic_t function only accepts the atomic_t type.
(2) Using the atomic_t type can avoid Compiler Optimization. Atomic operations are very important to using the correct memory address.
(3) The CPU architecture can be avoid
how to use redundant services to improve the QoS (response time, reliability) of composite services ). (S3) discusses how to find the weak point to be improved in the composite service, and proposes two methods: Brute-fource search and pattern-based search (which are not clear in this article. (S4) discusses how to use a method similar to n-Version Programming to improve QoS of a composite service.
