Find JIRA issues mentioned in Confluence Page

I have been walking through a lot of pages in internet but have not found any answer except one. However, the answer is not complete, so I will share my experience here. This feature is very useful, especially to summarize the issues found during certain tests, where the tests are reported in a confluence page. I found that there are so many questions about this, but Atlassian seems does not want to bother with this request. I found one way to do this by the following tricks Take one JIRA issue that related to the target confluence page (in this case, say it is GET-895) Find the global ID of a JIRA issue: http://bach.dc1.scram.com:8080/rest/api/latest/issue/GET-895/remotelink It will show the JSON like this: [{"id":28293,"self":"http://bach.dc1.scram.com:8080/rest/api/latest/issue/GET-895/remotelink/28293","globalId":"appId=662e1ccf-94da-3121-96ae-053d90587b29&pageId=105485659","application":{...

If and For in Wolfram Mathematica (with examples)

IF Condition in Wolfram Mathematica The syntax is as follows xxxxxxxxxx If [ condition , what to do if true , what to do if false ] Some examples Example 1. Simple command x x = - 3 ; If [ x < 0 , - x , x ] 3 Example 2. If condition in a function abs [ x_ ] := If [ x < 0 , - x , x ] abs /@ { - 3 , 2 , 0 , - 2 } { 3 , 2 , 0 , 2 }   For in Wolfram Mathematica The syntax is as follows For [ start , test , inc , what to do ] Some examples Example 1. Simple Loop xxxxxxxxxx For [ i = 0 , i < 4 , i ++, Print [ i ]] 0 1 2 3 Example 2. Another simple loop For [ i = 10 , i > 0 , i --, Print [ i ]] 10 9 8 7 6 5 4 3 2 1 Example 3. Print list a = { 10 , 3 , 9 , 2 } For [ i = 1 , i < 5 , i ++, Print [ a [[ i ]]]] 10 3 9 2

Mininet/Containernet Problem: Exception: Error creating interface pair (s2-eth5,s3-eth1): RTNETLINK answers: File exists

If you did not shut down the previous running mininet/containernet network (e.g. if you lose your connection to remote server), you will got the following error when you try to rerun your mininet network Traceback (most recent call last): File "./mynet.py", line 31, in <module> net.addLink(d2, s1) File "build/bdist.linux-x86_64/egg/mininet/net.py", line 403, in addLink File "build/bdist.linux-x86_64/egg/mininet/link.py", line 430, in __init__ File "build/bdist.linux-x86_64/egg/mininet/link.py", line 474, in makeIntfPair File "build/bdist.linux-x86_64/egg/mininet/util.py", line 202, in makeIntfPair Exception: Error creating interface pair (d2-eth0,s1-eth2): RTNETLINK answers: File exists In order to solve the problem, you need to clean up the previous running topology by using the following command sudo mn -c It will clean up all your cache. It will be something like this $ sudo mn -c *** Re...
