Y'all, I'm feeling awful wistful and nostalgic these days.

For a bit, I thought I missed the old days of Austin on Rails but, just between you and me, I just miss y'all. I miss spending an evening at the pub with you folks, dishing that hot goss and planning schemes and dreaming big dreams.

It's no secret what happened - life and kids and work and shifts in priority. I get it. We all get it.

You can't step into the same river twice, said Heraclitus. I say we prove that jerk wrong.

Let's get together and sit and drink and talk and think and scheme and dream - add a comment if you're interested along with dates and times that work for you. This ain't a democracy but we can do our best to accomodate the most we can. This also ain't exclusionary - if you're reading this and don't feel like you were a part of the OG AoR scene but for some reason want to join us, you're heckin invited too. I've got a drink and a smile for all y'all.

# In case anyone is wondering how to easily use the :crypto hash or hmac API's from elixir-land, here you go.

File.stream!(filename, [:read, {:read_ahead, 65535}], 65535)
|> Enum.reduce(:crypto.hash_init(:sha), &:crypto.hash_update(&2, &1))
|> :crypto.hash_final
|> Base.encode16

# Line 3 opens up a stream, and we're reading in 64KB chunks from the FS which is roughly pretty efficient
# In line 4, we initialize our hash (which returns a context) and put that as the default value in the reducer
# The hash_update in the reducer returns the modified context. Remember arg1 is the item, and arg2 is the accumulator
