Run docker without sudo

By default, you have to run docker using sudo. When you try to run it without sudo, you will get

$ docker images
Got permission denied while trying to connect to the Docker daemon socket

In order to run without sudo, you will need to do the following steps

  • Add the docker group if it does not already exist
sudo groupadd docker
  • Add the user to the docker group. If you want to add the current user, you can just use this
sudo gpasswd -a $USER docker

If you want to add, say user user1, then you should just do

sudo gpasswd -a user1 docker

After you do the above steps, log out and now you can run docker without sudo.

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

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":{

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
