I'm currently working my way through Jeremy Kun's A Programmer's Introduction to Mathematics. One of the exercises in Chapter 2 asks you to create a web app to implement secret sharing using polynomial interpolation. I went a little overboard and made PolyShare. I put a bit more effort into the app than strictly required to answer the book question and this post goes into some of the details.
I recently setup a couple of static sites by hand using CloudFront in front of S3 for https. I decided the next time I needed to set one up I'd automate it using Terraform and Terragrunt and this blog post is a brain dump of my notes on that.
MicroConf Europe 2015 was without doubt one of the best conferences I've ever attended. The talks were great and so were the conversations with the other attendees. If you're interested in bootstrapping you should definitely get a ticket to a future one.
I ran into a little trouble hooking up websockets when playing with an
ember-cli front end app and a
phoenix backend server recently. I
thought I'd document what I did to get them working for others trying this out.
I make no claims that this is the best way to do things but it's working for
me so far. If you know a better way please let me know in the comments or by
OTP Supervisors can restart their children in four different ways and to better understand which one to use in a given scenario I wanted to summarise a few patterns I've seen.
I read a great post by Graeme Mathieson that walks through how he sets up a new Rails 4.2 project from scratch. At the bottom of the post he mentions it takes him half an hour or so. I've been meaning to play with Rails Application Templates and figured this would be a good opportunity to see what they can do and if they can cut down this boilerplate time.
Yesterday I went to Erlang Factory Lite in Berlin. It was a great day of presentations and chat about Erlang and Elixir. Highlights for me were hearing José talk about Elixir and chatting with Robert Virding at lunch after seeing his talk on Erlang.
A little while ago Paul Wilson tweeted about some troubles he was having while converting an example from the Erlang and OTP in Action book to Elixir and adding tests. I'd just been doing the same thing and I wanted to expand on my reply to him here.
