Here's a top tip to avoid:
Ironbark smoke is abso-fucking-lutely vile. Do not use a couple of ironbark logs in your smoker unless they have completely burnt down to embers and can be used to ignite something that doesn’t make everything taste like sadness and other people’s headaches.
I just managed to ruin an entire barbecue this way. Learn from my stupidity: just never do this.

mix format and the ugly indent highlighting error
I had a bit of a mystery that was bugging me for ages. After enabling automatic formatting for Elixir files in VSCode, I was getting ugly highlighting that looked like this:
It turns out this is a feature of the RainbowIndents extension to show you where you have inconsistent indenting (e.g. 3 spaces, when everything else is 2).
The problem with this is mix format has unchangeable opinions about indenting, such as in a with statement, where it cares more about alignment than even/odd indent boundaries.
The fix is to exclude indentation errors for Elixir. In your settings.json add this:
With that in place, we now get plain ol' rainbow indenting:
This first appeared in a forum post on community.fly.io
I've updated it a bit with some clarifications and a fix for a version-clash issue I had.
$ mix phx.new hello --umbrella --no-ecto --install
$ cd hello_umbrella
Enable server in config/runtime.exs:
config :hello_web, HelloWeb.Endpoint, server: true
Add elixir_buildpack.config with the preferred Erlang and Elixir versions:
$ cat <<EOF>./elixir_buildpack.config
elixir_version=1.14
erlang_version=24.3
EOF
I had problems with too-specific versions in the above, so just use major versions, e.g. elixir_version=1.14 versus elixir_version=1.14.3-otp-24
Deploy the assets from within the web app directory:
$ cd apps/hello_web
$ MIX_ENV=prod mix assets.deploy
$ cd ../../
$ fly launch
Answer “no” to deploy request and leave fly launch, then set up the secret:
$ export SECRET_KEY_BASE=$(mix phx.gen.secret)
$ fly secrets set SECRET_KEY_BASE=$SECRET_KEY_BASE
Deploy:
$ fly deploy
Enjoy your app!
$ fly open
and the umbrella application is finally happily up and running!
Besides the steps above, here are the summary of the current differences in how Fly handles deployment between plain and umbrella.
to deploy an Umbrella via Fly:
server: true in config/runtime.exselixir_buildpack.config file to the projectSECRET_KEY_BASE executing fly secrets after fly launch and before fly deploy (you can’t just export it to an environment variable)iperfon MacOS:
brew install iperf
on Linux:
sudo apt install iperf -y
iperf -s
This waits for incoming connections from clients. Designate another machine as a client and run this command, substituting the IP address of your server machine for the sample one here:
iperf -c 192.168.1.2
Setup was:

When setting up profiles for AWS locally, start with your own credentials as default, then add profile entries for the different environments. e.g.
# ~/.aws/config
[default]
aws_access_key_id=AKIAIOSFODNN7EXAMPLE
aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
[profile staging]
role_arn = arn:aws:iam::0987654321:role/staging
source_profile = default
region = ap-southeast-2
output = json
[profile prod]
role_arn = arn:aws:iam::5678901234:role/prod
source_profile = default
region = ap-southeast-2
output = json
Well, of course Snoop Dogg has a cookbook with an introduction by Martha Stewart, and yes, I did buy it, thanks for asking.
Quick review: this cookbook is ideally something you give to a stoner teen that’s about to move out of home for the first time. The recipes are super-basic, with some nice twists, but require no complicated ingredients and the processes will not stretch anyone’s brain.
The layout and text are a lot of good, clean fun and nothing is taken too seriously. From that point of view, he’s done a great job at making cooking for yourself more accessible.
I’d keep this to give to my daughter when/if she moves out, but she’s already awesome at making schnitzel, bake cakes and muffins, etc. and she’s only 12, so I think she’ll be fine by the time she’s in her late teens…

Mucked around trying to get this right before realising I'd left out the + symbol in the format string. Derp.
Since I've been playing around with using Obsidian to organise myself, I tried out some of the MathJax support. These are some examples I've tinkered with.
An example of inline MathJax $\alpha, \beta, …, \omega$
$$\begin{matrix} 1 & x & x^2 \ 1 & y & y^2 \ 1 & z & z^2 \ \end{matrix}$$
$$ \begin{vmatrix} a & b \ c & d \ \end{vmatrix}=ad-bc $$
$$ \sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6} $$
$$ 10^{10} $$
$$ {x^y}^z $$
$$ x^{y^z} $$
$$ x_i^2 $$
$$ x_{i^2} $$
$$ \Biggl(\biggl(\Bigl(\bigl((x)\bigr)\Bigr)\biggr)\Biggr) $$
$$ \left(\frac{\sqrt x}{y^3}\right) $$
$$ \frac ab $$
$$ \frac{a+1}{b+1} $$
$$ x \approx y $$
$$ \sqrt[3]{4} $$
$$ \infty $$
$$ \aleph_0 $$
$$ \nabla $$
$$ \partial $$
$$ \Im $$
$$ \Re $$
The new improved Ozzie term for “Abbreviation” shall henceforth be known as a “brev”.
As in:
“I brevved it” “it's a brev” “I'm brevving it”
Let's make it happen, people!
Our reputation as the dimunitive-superpower of the world is at stake.
