Horizon is a subproject of OpenStack that provides a Web front-end console (called a dashboard) to demonstrate the functionality of OpenStack. Usually, we start from horizon, Dashboard to understand the OpenStack. In fact, Horizon does not add any new functionality to OpenStack, it only uses the OpenStack part of the API, so we can extend the horizon function and extend the
You can see that all clients have issued certificates. the "+" sign is successfully issued. if the certificate has not been signed, you can use
Puppet cert -- sign node1.canghai.com
To issue the certificate. after the certificate is issued, run
Puppet cert list -- all
The certificate has been issued.5. install the puppet dashboard on the server.Install mysql

test case starts with a line contains three number N, M (2
OutputFor each test case, you shocould print the minimum steps. "Bad Luck !" Will be print, if they can't meet each other.

Sample Output11Bad Luck!
S and Z are in the same maze. One of them takes one step, and the other takes one step in the opposite direction. How many steps can be taken to the same location or the two are adjacent?

is the statistical value to be allocated. (X1, Y1, Z1 )... A total of eight points represent the center coordinates of the eight statistical intervals. The above formula uses the Mark H (x1, Y1, Z1) to represent the statistical intervals to be accumulated. This formula is used in programming, but I use the bin label to represent the bin block, just as in the preceding 3D histogram diagram (Binx = 1, biny =
mechanism starts, the algorithm iterates through the zval of the element/member within the Zval array/class and RefCount minus 1, if the zval is reduced to 0 after the traversal is completed, It means that this zval is a memory garbage that he will be destroyed, see the example below
Copy Code code as follows:
$a = Array (1, 2, $a, $a);unset ($a);
Easy to know $a pointing zval, assuming Z1 refcount=3,is_ref=1
When unset ($a) e
describe what I expect to observe on page loading. TDD allows me to focus on one problem at a time, write only enough code to pass the test, and then proceed. In this test, I will use a simulated object framework named NMock2 to build an interface simulation implementation.

In my MVP implementation, I decided to attach the dashboard to the view that will work with it. It is always good to create an object when the object can work
Elasticsearch Kibana Installation notes
Kibana is a dashboard used for ElasticSearch analysis and query. It is worth noting that Kibana puts the analysis before the query, which is probably distinguished by other clients.
For more information about Kibana, see here.
Install Kibana
In addition, I still use head and bigdesk. Of course, their positioning is almost different. Head is easy to use for data browsing and query. bigdesk is used for ElasticSear

We know that the coordinates of the triangle vertices are (x1, y1, z1), (x2, y2, z2), (x3, y3, z3), (x4, y4, z4 ), you can use either of the following two methods to calculate the volume of a single triangle:
1. Use the hybrid product of Vectors

This is the formula for z rotation. The same method can be used to introduce the x rotation, y rotation formula. Summarized as follows:
