@ -9,7 +9,7 @@ Vertical Bars In Graphite
I am working with txStatsD and Graphite. I was having the hardest problem looking through the txStatsD code today finding how to graph something as an event, not a data point. I eventually went into every option on the graphite dashboard and found an option to make a bar.

This is the option that you must use when you want to mark events. For example we want to know “Server restarted”, we would use this technique, as it doesnt make sense to aggregate “server restarted”. Using nonzero as infinite is a good way to show an event took place.

Last night I migrated a lot of my old code from one GitLab account to another (`tyrelsouza <https://gitlab.com/tyrelsouza>`__ to `tyrel <https://gitlab.com/tyrel>`__) in an effort to clean up some of my usernames spread across the world. While doing that I noticed my `django-dbfilestorage <https://gitlab.com/tyrel/django-dbfilestorage>`__ Python module that has been sitting and rotting for three years. I played around a little bit in order to port it to Python 3.9, but I ran into some base64 errors. I tried a little bit but it was late and I couldn't figure it out. My resolve is that I have been away from Python for too long so the little things - that I knew and love - had fallen away. I mentioned this to my friend Alex and he said *"make a barebones github cli (readonly?) with issue viewer, and stats display"*. I've embarked on a journey to refresh my Python well enough to repair DBFS.

I knew I wanted to use ``httpx`` as my network client library, it's new, fast, and I have a couple friends who work on it. I started with a barebones ``requirements.in`` file, tossed in ``invoke``, ``pytes``\ t, and ``black``. From there I used ``pip-compile`` to generate my ``requirements.txt`` - (a tip I picked up recently while adding Pip-Compile support to the `Tidelift CLI <https://tidelift.com/cli>`__) and I was good to go.
The `docs for the GitHub API <https://docs.github.com/en/rest/overview/resources-in-the-rest-api#schema>`__ are pretty easy to read, so I knew all I really needed to do was set my ``Accept`` header to be Version3 and I could view the schema. With the schema saved to a ``.json`` file I then wrote a ``GHub`` class to pull this data down using ``httpx.client.Client.get``, super simple! The only two endpoints I care about right now are the user and repos endpoints, so I made two ``get_`` functions for each. After a little bit of work - which I won't bore you with the super intricate details - I have a functional cli.py file. For now, the only interaction is a propmt from ``rich`` for a username, and then you get a fancy table (also from ``rich``) of the first page of results of repos, stargazer/watchers/forks counts, and a description.

Prompting for the username and showing my table of repositories.
It was a fun evening of learning what's changed in Python3 since I last touched it, especially as I've spent the majority of my career in Python2.7. Type annotations are super awesome. I'll probably pick it up again once I get some more free time later in the week. It's also nice blog fodder! I already have a million things I want to do next - pagination, caching, some more interaction.

One of the first things I did when I moved into my house was research some automation. I initially bought a half dozen `ESP8266 devices <https://www.amazon.com/gp/product/B07HF44GBT/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1>`__ and tried to figure out what I could do with them. I found Home Assistant and set that up on my server computer, along with ZoneMinder for security cameras.

I knew I would need some sort of relay (domain purchased from is gone) and `reed switches <https://www.amazon.com/gp/product/B00LYCUSBY/>`__ to trigger the door and sense its position, so I purchased some from the internet. But my friend Paul said all I needed was a `MOSFET <https://www.amazon.com/gp/product/B071J39678/>`__ so I bought one of those too. I tried to figure out how to trigger the door with a mosfet, but I was never able to. I won't document those failures.

All together this is shown on my Home Assistant Lovelace dashboard using two cards, one that shows a closed door, and one with an open door (both actual pictures of the door!) with a button to open it. Once it opens or closes the other card switches into place, Home Assistant at least at the time didn't have good conditional cards like I wanted.
