Overview of LAN Switches The LAN switch has developed into a more expansive space from the traditional hub-and-LAN. For example, Cisco's Catalyst 5000 series LAN switch includes an integrated switched hardware architecture that supports switched 10-mbps Ethernet and 100-mbps Fast Ethernet, with Fast Ethernet, FDDI, switched token Ring, and layer 3rd switching capabilities. This class of switches can provide exchange access to workstations, servers, n

Environment preparation Use two machines, one to do Docker private warehouse, one to do Docker image submission Make sure Docker is installed on both machines and start the Docker service The name of the Docker private warehouse is: Docker-registry, IP: 192.168.1.101 The Docker image is submitted with the name: Docker-app, IP 192.168.1.102 Installation of private warehouses and push of mirrors Execute the following command on the Docker-registry machine:docker run -

The different transaction isolation levels in 5 are defined in spring:1.Isolation_default(This configuration can be used in general); This is a Platfromtransactionmanager default isolation level that uses the default transaction isolation level of the database.2.isolation_read_uncommitted(uncommitted) This is the lowest level of isolation for transactions, and it allows a transaction to see uncommitted data for that transaction.This isolation level produces dirty reads, non-repeatable reads, and

synchronous operation----can use various methods of the deferred object to specify a callback function.Let's look at a concrete example. Suppose there is a time-consuming operation, wait:var wait = function () {var tasks = function () {alert ("Execution complete!　　　　");　　　　};　　SetTimeout (tasks,5000); };However, by doing so, the done () method executes immediately, not the function of the callback function. The reason is that the $.when () parameter

!") "); }; SetTimeout (tasks,5000); }; We specify a callback function for it, what should we do?Naturally, you will think that you can use $.when (): $.when (Wait ()) . Done (function () {alert ("Haha, success! "); }) . Fail (function () {alert ("Error! "); }); (Run code example 5) However, by doing so, the done () method executes immediately, not the function of the callback function. The reason is that the

! "); }) . Fail (function () {alert ("Error! "); }); (Run code example 4) This code means that you perform two operations $.ajax ("test1.html") and $.ajax ("test2.html"), and if all succeeds, run the callback function specified by done (); fail () if one fails or fails The specified callback function.V. Normal operation callback function interface (upper)The biggest advantage of the deferred object is that it extends this set of callback function interfaces from Ajax operations to a

operation----either an AJAX or a local operation, whether asynchronous or synchronous----can use various methods of the deferred object to specify the callback function. Let's look at a concrete example. Suppose there is a time-consuming operation wait: The code is as follows Copy Code var wait = function () {var tasks = function () {Alert ("Execution complete!") ");};SetTimeout (tasks,5000);}; We specify a cal

Before you deploy Docker, you need to preview the Docker command Docker basic command Docke pull nginx# Download Nginx mirrors Docke Push 192.168.161.117:5000/os/centos #上传本地制作的镜像到本地镜像库 Docker Images #查看下载到本地的镜象 Docker tag 980E0E4C79EC 192.168.161.117:5000/os/centos #将Image ID mirrored to 980E0E4C79EC mirror marked as 192.168.161.117:5000/os/ Centos Docker run-it

the database. Dirty reading, non-repetition reading, phantom reading (1) Dirty reads: dirty reading means that when a transaction is accessing the data and the data has been modified and the modification has not been submitted to the database, another transaction accesses the data and then uses the data. For example: John's salary is 5000, and his salary is changed to 8000 in transaction a, but transaction a has not yet been submitted. Meanwhile
