Add pre-compiled Elixir on OS X

So, I've been a big Erlang fan for a few years now, and then found out about Elixir:  what I would describe as kind of a Ruby-ish creamy frosting on top of Erlang. But I'll address more on both in future. Right now, I thought I'd just give a quick and dirty way to add Elixir, if you've already got Erlang installed (hint: check-out this Erlang Solutions link for a pre-compiled Erlang solution).  You can also use brew to install both, but I have found that with the simplicity of brew, you give up having the most current version of software.  In both cases. The pre-compiled zip for the most current version of Elixir can be found here.  Unzipping reveals a folder containing everything you need.  For simplicity's sake, keeping everything pertaining to Elixir all within this folder makes the most sense.  By doing so, all that's needed is to position the folder, and then make links to all the executables in a directory already in our path.  Through the link, the OS will find the program, and everything the program needs (libs and such) are already where it expects to find them (in the folder). Rename the folder to: "Elixir".  The reason I do this is so that I can easily find it later, and just drag the old folder to the trash, replacing it with whatever the current version is (and not have to change any of the links-- drag and drop replacement).
NOTE:  the following assumes that you have "/usr/local/bin" on your path.
Now, move (mv) the newly renamed folder to the directory: "/usr/local/", so that the final directory path is now, "/usr/local/Elixir". Again from the terminal, change directories (cd) to "/usr/local/bin", as it's from here that we're going to set every thing up to play nice. With the current directory in the terminal now, "/usr/local/bin" add the following soft links to each of the Elixir executables (beginning '$' represents the terminal prompt in all examples): 

$ ln -s /usr/local/bin/iex  iex

$ ln -s /usr/local/bin/elixir  elixir

$ ln -s /usr/local/bin/elixirc  elixirc

$ ln -s /usr/local/bin/mix  mix
Now, you can double check everything: 

$ iex -v
$ elixir -v
$ elixir -v
$ mix -v
Provided everything is set up correctly, and you received version number's from each command, you're ready to rock with Elixir.

Passing Functions and Lambdas into Functions with Ruby

Ruby's New Style of Lambda Functions f = ->( m ) { p m } f.call( 1 ) #=> 1 Which of course means the same thing as: f = lambda { |n| p n } f.call(1) #=> 1 Ruby Proc Objects p = Proc.new { |n| p n + 2 } p.call(2) #=> 4 Using a Function as a Closure in Ruby def domo( k ) ->(m) { p m + k } end z = domo( 5 ) z.call( 5 ) #=> 10 Function :domo takes a single parameter. Within :domo , we create a lambda that takes a single parameter, and adds that parameter to the value :domo takes in as its parameter. Then, we assign z to be the result of the lambda in :domo with its 'k' parameter loaded with 5. When z is called, we pass (another) 5 to it. This parameter loads the lambdas n parameter. The lambda executes, essentially adding n (5) + k (5) and yielding the result of 10. The thing about closures such as this is, we can load the initial value of the lambda to be whatever we want it to be when assigning the function :domo '...

Fun with Meteor, React, and React-Bootstrap

React-Bootstrap is pretty cool. I decided to play with it a bit.  Here are the basics. In an already set up Meteor project (set up for React), it is added thus: npm install --save react-bootstrap Once this is done, you also need to add a bootstrap library. It could either be the twitter bootstrap meteor package, or you can link to it. For the purpose of my demo, I just grabbed a couple links from the React-Bootstrap site that they had handy for pulling in from a CMS: index.html <head> <!-- Latest compiled and minified CSS --> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap.min.css" rel="stylesheet"> </link> <!-- Optional theme --> <link href="https://maxcdn.bootstrapcdn.com/bootstrap/latest/css/bootstrap-theme.min.css" rel="stylesheet"> </link> </head> Now, let's make a layout, and then create a component tha...

OS X Process-Fu 101

OS X is of course a variety of BSD Unix, not Linux. Often is the case where Linux commands either don't work, or don't give the same results on OS X as they do on Linux. For example, a basic netstat will give you a long list of the processes making network connections on your box. On Linux, various command line options can help you drill down from there, to get the answers to more specific queries. On OS X, those same queries don't give you the answers you're seeking. This isn't a compare and contrast article between Linux and OSX. Instead, I'm just noting various commands that can give answers to some basic questions. On OS X, for example, to get an answer to the question: "What process is running on port 50224?" we would use: sudo lsof -Pn | grep 50224 This will give you a list of everything connected to port 50224, sans any kind of headings. A much more abbreviated command that will give you essentially the same things, but with column...
