If you were to give recommendations to your "little brother/sister" on things that they need to do to become a data scientist, what would those things be?

I think the "Data Science Venn Diagram" (http://drewconway.com/zia/2013/3/26/the-data-science-venn-diagram) is a great place to start. You need three things to be a good data scientist:

• Statistical knowledge
• Programming/hacking skills
• Domain expertise

Statistical knowledge

Twitter's API doesn't allow you to get replies to a particular tweet. Strange
but true. But you can use Twitter's Search API to search for tweets that are
directed at a particular user, and then search through the results to see if 
any are replies to a given tweet. You probably are also interested in the
replies to any replies as well, so the process is recursive. The big caveat 
here is that the search API only returns results for the last 7 days. So

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.
