Install Python 3 and use VirtualEnv (OS X)

  1. Install xcode: $ xcode-select --install
  2. Install homebrew: $ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
  3. Create .bash_profile: $ touch ~/.bash_profile
  4. Put this line inside .bash_profile: export PATH=/usr/local/bin:$PATH
  5. Install python3: $ brew install python3
  6. Create virtual environment. To make it easily found, create it under home: $ cd ~ && pyvenv arwan
  7. Activate the virtual environment created: $ source arwan/bin/activate
  8. Now you can start working in the new virtual environment. Note that it is worth to look at requirements.txt to see required packages on certain projects.

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

Android studio in ubuntu - problem: 'tools.jar' seems to be not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE.

I love coding, especially Java. Because Android apps is written in Java, I would love to make one as well. Unfortunately, when I tried to install Android Studio on my Ubuntu yesterday, I got this error message: 'tools.jar' seems to be not in Android Studio classpath. Please ensure JAVA_HOME points to JDK rather than JRE. When I google on this error, there are so many websites and forums discuss about this error as well as the solutions. However, in linux (or ubuntu in my case), sometime we have different environment so that the solution will not always work (sometimes we have to do another thing before or after that solution). And this also happen in this case. Here are what I did then: 1. Know what exactly the problem is: the problem is that the JAVA_HOME in my system did not point to JDK. Instead, it points to a JRE. JRE can only be used to run java applications, not to build them. 2. Check the java path used by the system. In terminal, I typed the following: ...
