Learning OCaml

Similarly to what exists for Haskell, I wanted to make a curated collection of good resources for getting started with OCaml.

Installation and getting started

Follow the installation instructions from the Real World OCaml book available here. This will get you accustomed to

Opam, the package manager, which also gives to the possibility of switching between OCaml versions.
Utop, a modern interactive toplevel
Set up of your enviroment, in particular #use "topfind" so that Utop finds your packages installed by Opam.

LambdaContext

Here is the raw output from examining the Python LambdaContext context object in a AWS Lambda function when called from a CloudFormation stack. More information on the context object can be found here : http://docs.aws.amazon.com/lambda/latest/dg/python-context-object.html

LambdaContext object : `print(context)`

<__main__.LambdaContext object at 0x7fd706780710>

LambdaContext vars : `vars(context)`

There are a bunch of ways to start. The main thing is to get some simple programming environment where you can try things and learn from your mistakes. Depending on how you like to learn you might want to start with a good book. I haven't read it myself but I've heard good things about How to Design Programs which you can read online here http://www.htdp.org/. There are also sites like https://www.codecademy.com/ and https://studio.code.org/ that have online instruction for starting programming. The latter may be aimed somewhat at kids but that doesn't really matter.

Another approach is to start by learning HTML, the language used to make web pages, which is not exactly a programming language but which will let you play with making a computer do something as well as giving you a chance to learn some of the mechanics of dealing with files and debugging your mistakes, etc. From there you can learn to make web pages more dynamic with Javascript, which is a programming language. In this case your programming e

Intro

The plan is to create a pair of executables (ngrok and ngrokd) that are connected with a self-signed SSL cert. Since the client and server executables are paired, you won't be able to use any other ngrok to connect to this ngrokd, and vice versa.

DNS

Add two DNS records: one for the base domain and one for the wildcard domain. For example, if your base domain is domain.com, you'll need a record for that and for *.domain.com.

Principles of Adult Behavior

Be patient. No matter what.
Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
Never assume the motives of others are, to them, less noble than yours are to you.
Expand your sense of the possible.
Don’t trouble yourself with matters you truly cannot change.
Expect no more of anyone than you can deliver yourself.
Tolerate ambiguity.
Laugh at yourself frequently.

An API search engine in Elm for Elm

Elm is a statically typed functional language that compiles to JavaScript. It's well-known for its developer experience: the compiler provides nice error messages, the package system enforces semantic versioning for all published packages and makes sure every exposed value or type has some documentation and type annotations.

Today, single page web apps are driving many websites that we use each and every day. Instead of having your browser request a new web page for each and every action you perform on a web page, single page web apps may load all in one request to smoothly and quickly transition with every action you perform.

When building single page web apps, you may decide to retrieve all of the HTML, CSS and Javascript with one single page load or dynamically load these resources as the user moves about your site. Either way, it can be a pain to bundle all of these assets together for the end user to download from your web server. This is where webpack comes into play.

webpack does all of the heavy lifting bundling all of your HTML, CSS and Javascript together. If you write your site all from scratch or depend on dependencies from npm, webpack takes care of packaging it all together for you. It has the ability to take your single page web app, cut out all of the code you don't need, then packa
