The example of this article is about jquery's simple implementation of web-layer expansion and contraction effect. Share to everyone for your reference. Specifically as follows:
This demonstrates the jquery Web layer expansion, layer shrink code, with buffering animation effect, click on the specified text or button, you can expand the specified layer, click again will be the layer, similar effect on the i
Can the ipad Pro be plugged into an expansion card? The ipad Pro can not plug an expansion card.
The ipad Pro thickness is 6.9 mm, 0.8 millimeters thicker than last year's ipad Air 2, and weighs more heavily than the ipad Air 2, which feels slightly bulky. But the ipad Pro's size and storage capacity have increased. The ipad Pro offers 10-hour endurance, and the display area is nearly 10% larger than other

PHP Dynamic Expansion Module installation所谓动态模块,就是一个独立存在的.so文件。php一旦编译完成后,想要再增加一个模块的话要么重新编译php,要么直接编译一个扩展模块,(生成一个.so文件),然后在php.ini中配置一下,就可以被加载使用了。这里我们用redis来做实验。First we go into the cd/usr/local/src/directory.First we want to see which modules are loaded in PHP/USR/LOCAL/PHP/BIN/PHP-M//View moduleWe found that there was no Redis module, and then we went to download a module.wget Https://codeload.github.com/phpredis/phpredis/zip/developThen rename the
Insus.net in the near period of time at the request of friends, write a GridView multi-layer nesting and folding and expansion. This feature of the GridView multi-layer nesting is not a problem, because has done an infinite number of times, but the folding and expansion of the function, but spent a lot of time (online looking for information), although found information can be referred to, or understand it,
needs to be allocated 17 times100,000 need to be assigned 23 times1 million need to be assigned 28 timesTherefore, according to the actual situation, it is necessary to roughly allocate an initial capacity. But if your initial capacity is too large and the data is growing slowly, it is wasting memory.How to choose, or to see the specific application of the scene.(2), HashMap capacity growth modeHashMap mainly use arrays to store data, we all know that it will hash the key, the HA operation will
Kotlin Extension
Kotlin can extend the properties and methods of a class and do not need to inherit.An extension is a static behavior that does not have any effect on the extended class code itself.
Extension of the class, what a ghost. Anyway, I have never seen Java, the following look at the expansion of the Kotlin bar. I. Extension methods
is to add a method. 1. Extension methods can add new methods to existing classes, do not modify the original
daily 100w, suddenly jumped to 1000w, this time can take the data separation, we can according to user ID different distribution, If you take the form of%2, or%10 form, of course, this form of the future expansion has a lot of restrictions, when I from 10 partitions to 20, all the data have to repartition, then will be a very large amount of computation; Here are some common algorithms:Hash algorithm: Is the way to use user_id%;Range: can be divided
Previously built a CentOS (7.0, x64) VM, has not been aware of its hard disk space. Yesterday, the system suddenly pop-up warning, said the root directory space is insufficient.In this case, you can only add space to it.
I've actually increased my hard disk space, but to write this blog, I've added 10GB hard drives again.
On the premise of the virtual machine shutdown , first, through VMware to the virtual machine to add some hard disk space, the following figure:After clicking "Expand", wait a
The 4th Chapter RTOs the SMP expansion design and realizes the single core RTOs SMP expansion, needs to solve the system initialization, the task scheduling, the CPU synchronization and mutually exclusive, as well as the interrupt processing and so on aspect question, this article will propose the corresponding solution for these problems, and carries on the SMP extension realization on the uc/os-ii. 4.1 Sy
Expansion and collection of grouped aggregations in reports and techniques for dealing with irregular hierarchies (do not expand without child elements, delete + symbols)
The expansion and the effect of packet aggregation is very common in the SSRS, and sometimes there are some more special situations to deal with. For example, when grouping merge, some hierarchies are irregular, and some groups have two l

Docker container once started, the parameters can not be changed, production environment is the most common change is the port mapping, in order to solve this problem, then the first plan, this article lists two port planning scenarios, if there is a subsequent maintenance to increase the port mapping scenario, this paper also gives the dynamic port mapping expansion scheme.

Label:When our application reaches a certain scale, our data will skyrocket. The original database may not meet our read and write requirements. But the growth of data is a business-wide delight, but the bigger headache is how to achieve effective expansion. How to do it without error.The simplest is the sub-database table.So how does the database know which machine to read the data on?Like I had a 10w record before. Now consider placing the top 10w
