Plot Bubble plot using excel 2013

This is a way to address data of three dimensions, like heatmap or surface plot
But the sizes of bubbles instead of color/Z axis indicate the value you want to show over a 2D grid.

Insert -> In the charts area, click the scatter, choose bubble

Then select data. And then type in X value, Y value and Bubble size

In the example above, I set each datapoint to be an individual data series. So their colors look different

Git: fastforward --- Define your finished branch to be master branch

Figure 3-13. Hotfix branch based on master

You can run your tests, make sure the hotfix is what you want, and merge it back into your masterbranch to deploy to production. You do this with the git merge command:

$ git checkout master
$ git merge hotfix
Updating f42c576..3a0874c
Fast-forward
 index.html | 2 ++
 1 file changed, 2 insertions(+)

You’ll notice the phrase “fast-forward” in that merge. Because the commit pointed to by the branch you merged in was directly upstream of the commit you’re on, Git simply moves the pointer forward. To phrase that another way, when you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

Your change is now in the snapshot of the commit pointed to by the master branch, and you can deploy the fix.

Figure 3-14. master is fast-forwarded to hotfix

how to split linux command into multiple lines:

ls -l \
   --reverse \
   --human-readable \
   --full-time
       

Using the backslash in this way allows us to embed newlines in our command. Note that for this trick to work, the newline must be typed immediately after the backslash. If you put a space after the backslash, the space will be ignored, not the newline. 

(copied from http://linuxcommand.org/wss0060.php)

Troubleshoot:

avoid whitespaces disturbing the backslash, as mentioned here:
