They had split ergo boards back in 1983??? WTF who the heck keeps these row stagger boards going. This board looks like endgame material, If this thing was more normal, it’d kill a whole section of the ergo mechanical keyboard industry for good reason.

This keyboard layout looks weird af the mix of column staggar and row stagger is wild. Not sure if its genius or an abomination.
That solenoid though is absolutely wild though, I kinda want one TBH.
and the clear plate with the diodes laid out on it in a herringbone pattern is a very nice touch.

Very interesting approach to htmx [2] and fast api. It uses separate decorators for returning template partials and json that can be stacked to include both options on a single route. The templates are explicitly set in the decorator. Separate decorators are used for full page and partial pages. I don’t see an example of full and partial pages being combined. I think the demo app must be behaving in a spa like fashion where it does not get all of the data when it calls index and index will ask for user-list.

🌟 For when you really just want to serve some files over HTTP right now! - svenstaro/miniserve

miniserve is a sweet http server, replacement for python -m http.server. It’s fast, runs off a small binary, but why would I want to use it over something that already exists on most machines, because it includes a bunch of features like qr codes, pretty themes, and uploads. I’ve used python -m http.server many times to transfer files from one machine to another in a pinch, like at a family members house. But what if they have an android, windows, or something not easy to get a python repl running on, you can run miniserve and upload from their device rather than hosting from their device.

Background Tasks - FastAPI
FastAPI framework, high performance, easy to learn, fast to code, ready for production
fastapi.tiangolo.com [1]
fastapi [2] comes with a concept of background tasks which are functions that can be ran in the background after a function has been ran. This is handy for longer running functions that may take some time and you want to have fast response times.
Here is an example from the docs
from fastapi import BackgroundTasks, FastAPI
app = FastAPI()
def write_notification(email: str, message=""):
with open("log.txt", mode="w") as email_file:
content = f"notification for {email}: {message}"
email_file.write(content)
@app.post("/send-notification/{email}")
async def send_notification(email: str, background_tasks: BackgroundTasks):
background_tasks.add_task(write_notification, email, message="some notification")
return {"message": "Notification sent in the background"}

diskcache has a peekitem method that allows you to lookup the expire_time of a cached item without changing it. I recently used this to implement debounce for fastapi [2] background tasks with multiple workers running. since all the workers I care about are on the same machine, but running in different processes diskcache was a great option. All workers have access to the same disk, but not the same variables in memory.

Supply chain attacks are so big these days engineers definitely need to take these into consideration. It’s wild that such a simple attack vector hit some really big applications. This particular vector is so easy to avoid. You are already hosting web content, just curl the file and self host [1] the script, then you own it. That eliminates this attack vector all together, but doesn’t completely remove supply chain attacks, the js file can still hit external apis internally.
What I see has happened in this case is that the owner of the domain polyfill.io changed. so anyone who directly linked to them got a malware injected script used.
I can only imagine the number of applicatons that are not even being maintained anymore getting hit by this. TLDR, if you are taking something to production, where you are goind to deploy it and let it run, host the js yourself. these cdns are great for prototyping, but tread with caution.

Well spoken prime. Co-pilot is a fantastic tool for templating, boilerplate, or just getting something done that is just outside your knowledge or care to know. Bit if you really want to learn something, you need to use your hands. Reading the solution only gives you the happy path. This does not give you that path that most people would take, and completely misses debugging. If you are very new and learning it’s unlikely that you can write large blocks of code without running a test or a script to try it. Taking these shortcuts will hinder your ability to do it yourself.
If I were to devils advocate here, copilot is still not the greatest at the big picture, you still have to drive, and tell it I want to use python, fastapi [2], I want to load settings from .env. taking these shortcuts can help you move quick and get the big picture.

Interesting, linux supports 32 programmable buttons, special buttons that do nothing that hotkey programs like xbindkeys can pick up and run things, seems like it would be very intersting to use on a macro pad.

For job based containers pre-compile your pyc for faster startup.
Alpine linux is probably not what you want for python. Many packages such as postgres ship pre-copiled binaries that work for most linux distributions wich use glibc, but alpine uses musl so the binaries will be incompatable requiring you to need to install a bunch of build dependencies.

How to Configure DNS over TLS (DoT) Using Unbound DNS in OPNsense
Going beyond the basics of home networking
homenetworkguy.com [1]
Setting up DNS overTLS in opnsense has made my dns just a bit more secure and reliable. I recently had an outage of half the internet within my house. This also hit some of my friends and not some. It did not hit my mobile network. What seems to have happened is a dns issue with my isp not resolving some domains. This setup corrected my issue and I was back online more securely.
Note
I did try to setup the family resolver and found it was blocking some sites I am ok with. I decided to drop back to the vanilla resolver and let other services within opnsense control blocking where I can caontrol the whitelist myself.

Argo events is an event driven automation framework for kubernetes that can create kubernetes objects among other things based on events. I’ve been using native kubernetes cronjobs to kick off jobs based on a cron trigger.
For instance I am running reader.waylonwalker.com every hour, to rebuild the site and re-deploy it. It takes about two minutes to fetch every rss feed, so this is a nice application of a job compared to a web server fetching the feeds live. Now my posts may be up to an hour stale but they load fast.
Argo events takes event drien architecture to the next level allowing to be triggered by many more things, and do many more things than creating a cron job. I’m definitely thinking about dropping this in my homelab [2].
