A friend recently wrote “our personal database , about how they maintain a postgres database for various projects. I wrote something similar when I wrote about my personal api , though Rubenerd’s post made me want to write a little bit more about it.

Since I am already using django for various projects, my personal API is also built on Django. While I could modify thing directly using something like pgAdmin, building on Django means I can take advantage of the models and admin built in to Django.

There have been a few times while working with Django , where I have wanted to triger something only if the instance changed. Since Django provides a robust signals system, I decided to use that for my prototype.

First we need to import the packages we will use.

from django.db import models
from django.db.models.signals import post_save, pre_save, ModelSignal
from django.dispatch import receiver
from django.forms.models import model_to_dict

Next, we want to handle our pre_save signal. We want to store a snapshot of the original object so that we can compare it later.

Recently there is quite a lot of back and forth regarding ActivityPub based projects and Bluesky.

Drinking more water.

Similar to a friend figuring out water this is how I get myself to drink more water.

1. A while back, I bought several 500 ml bottles from Daiso for about ￥ 100. At the beginning of the day I fill each of them up and put them in the fridge.
2. Keep one at my desk. If I have a bottle next to me, I will reflexively drink sips while working.
3. Any time I empty a bottle, I scan an nfc tag on my desk to record it, and then get a new bottle from the fridge.

As a bonus, this also means short forced breaks throughout the day to empty water.

3D Printing is still somewhat magical. Several years ago, a friend gave me a ender3 that they were not using, and I have been using that for a few small projects, but it is an old printer so it is not always reliable.

Recently I have been considering 3D printing some more, and would really like to get a newer one. Not unexpectedly, my recent youtube recommendations and now subscriptions have included quite a lot of 3D Printing, such as channels like Print Farm Academy or Macy Makes talking about creating 3D printing businesses or Hands on Katie showing all kinds of things that she makes with 3D printing.

I am not particularly fond of Kubernetes and have tried to avoid it as much as possible, but at times it feels somewhat inevitable. In order to have a little more familiarity with how it works, I decided to go through Kubernetes the Hard Way and setup a cluster.

Note: If I was really going to use Kubernetes, I would likely use some project that managed it in a better way. Going through this excercise is the same reason I went through Linux from Scratch years ago to better understand how things were assembled together.

One advantage of having my own personal api is that I can put various useful scripts under a single repo and have them run. I have been using raindrop for several years, to collect bookmarks to read later. Often, while researching things, it would be useful to automatically group things into collections, so I wrote some celery tasks to help with this.

While USB-C mostly defines just the physical connector, the increase in Power Delivery options makes it a more appealing option for all kinds of devices. In some ways, I am lucky as an American than lives in Japan, most devices use the same plugs, and I do not do so much traveling as to need all kinds of adapters. That said, it is still somewhat annoying (first world problems) to have many different power bricks and large plugs on my desk. Is it yet feasible to move more small devices to USB-C and ditch all these power bricks ?

I have long been inspired by Aaron Pareki and his pk3 tool for his website. With some searching, one can find other kinds of personal management systems on GitHub or other developers writing about their own personal api with links to other examples. As a developer myself, I have my own personal API that I am able to add to as wanted.

In the interest of choosing boring technology my personal api is powered primarily by django and celery .

Previously, I would subscribe to many projects on GitHub to watch for releases. Over time, it gets difficult to check all your subscriptions as GitHub does not seem to have an easy way to request this list from the API. It can also increase some noise in your inbox from time to time. Recently as part of my slow migration off of GitHub, I have been switching to following the release feed in RSS.
