21. Two programmers are chatting: "I met a hot girl yesterday. I took her home and immediately started to kiss with hunger. She sat down on my keyboard and then ......" "Do you have a computer at home? What is the CPU model ?"
22. Why do programmers like UNIX: unzip, strip, touch, finger, grep, mount, fsck, more, yes, fsck, umount, sleep?
23. Computers are high-speed dummies, while programmers are low-speed
span, we re-enter national highway 224 before the town of nansheng. Looking at the miles buried along the National Highway, the relentless and excited shouted, "224 kilometers have not been missed !", In the past, she wanted to take a picture on national highway 224 at the 224 km logo. After crawling a small slope, I finally found the logo, but the idiot has rushed over. Only four of us stayed to take a photo. I have also done this on national highway 325 in Beihai, Guangxi,

windows. The problem is that even if you can do it, you may not do it. This is the so-called force of culture. In theory, you can read and study anywhere, but the most efficient place is the classroom and study. On the comfortable sofa in the living room, you can pick up the TV remote control.So in my own experience, it is better for a programmer to use a Unix-like operating system. It can help you improve your level and work efficiency in your daily life. This is a bit similar to photography.
. megui is very powerful and is the best choice for converting high-quality AVC videos. There are many containers that can be output, now, you can directly output MP4 files that can be played by PSP. (For a long time, this type of Universal Video suppression tool cannot directly extract videos that can be played by PSP)
Unfortunately, this software does not seem to have a Chinese version.
Why don't we recommend some previous dummies for videos with xf
. Because it is a learning phase, we use the debug version. In actual projects, we need to use the compressed version for release to reduce the file size. Next, we start our first Hello world Program with a consistent tradition in the programming world.Create a new one, change the file name to hello.htm, open it in a text editor, and write the following code:

Getting started with CSS-basic style sheet syntax (1)
Insert the webpage before and after the style sheet.
To better understand the role of a style sheet, Let's first look at a CSS application instance. In this example, you can easily compare the differences between the two web pages before and aft

your Azure Deployment Project, find package.xml:
Locate the Jetty startup line and add the JMX parameter after Java start : -dcom.sun.management.jmxremote=true-dcom.sun.management.jmxremote.port=1099 (the port can be defined by itself)-dcom.sun.management.jmxremote.ssl=false-dcom.sun.management.jmxremote.authenticate=falseFind Jetty Start line:?the above JMX parameter is added to the Jetty in the startup parameter

From the above output, we can know that the process number executed by tomcat is 5144.
2. Killing Processes
Run the following command:
pid = 5144 kill -9 5144
You can completely kill tomcat.
4. Exceptions
When I start IDEA tomcat again, the following error is reported.
Connected to the target VM, address: '2017. 0.0.1: 50363
run the so-called agent, like LoadRunner, to get a larger number of concurrent users. Depending on the signature of the official JMeter document, you need to do this yourself, but don't worry, it will be very simple ^_^1. Install JMeter on all machines that expect to run JMeter as load generator, and make sure one of the machines acts as a controller, and the other machine as the agent. Then run the Jmeter-server.bat file on all the agent machines-assuming we use two machines 192.168.0.1 and 19
