We explore the universe to understand the mysteries of the vast starry sky, but we are rarely aware of the dangers of hiding in the depths of the universe, they are always staring at our Earth. If aliens visit us, the result may not be the same as that of Columbus when he stepped onto the continent of America. This is a historical and realistic situation.The dor

First, in some respects, monitoring is still poor and this will be explained in more detail below.
Second, monitoring is still a problem because more and more companies are starting to turn to MicroServices (microservices).
What monitoring tools are being used by the enterprise?Although many new tools have emerged in the market since 2011, many "old" open source tools, such as Nagios and Zabbix, still dominate the market. The interview found that 70% of companies are still us
traditional wireframe, the hand-drawn wireframe will have concrete content, text, icons, and pictures. So my design style and some ideas will be tested and validated in this sketch. I also use a freehand wireframe to test the elements of the user interface to make sure they are available. We'll test all the scenarios, and sometimes we'll have some design that's somewhere in between.
Sometimes when I need a formal presentation to my client, I use ink instead of
is a key building block for MEF. Composableparts supports applications to expose and use component extensions through exports and Imports.
contracts is a means of communication between Export and Import components. Contract are typically implemented through the Interface class. Contracts supports the MEF composableparts to avoid dependencies or tight coupling with other components.
conditional Binding allows you to load components that meet a specific metadata standard. In the example above,

GraphicsMagick is a branch of ImageMagick, which is faster and consumes less resources than ImageMagick, and large image processing sites such as Flickr and Etsy are already using TA.When using GraphicsMagick, the most frustrating is how to match graphicsmagick environment, consulted a large number of articles, are noted in Linux can not use Cmd.setsearchpath (path); , but after my experiment, is OK, and with

2. use rust to create php extensions
Introduction: In last October, I had a discussion with Etsy about how to expand writing for an explanatory language like PHP. Ruby or Python is now much easier than PHP. We have talked about the obstacle to writing a program that successfully creates Extensions. they usually need to be written in C, but i

When using GraphicsMagick, the most frustrating thing is how to configure the GraphicsMagick environment. I have read a lot of articles and noted that cmd cannot be used in linux. setSearchPath (path, you just need to put the path in the configuration file.
