Big Clive's video description:

This is not a sponsored video.  I feel it's important that people should know about this evolving technology, and Naomi is working on making it affordable.

During the pandemic YouTuber Naomi Wu presented plans for traditional mercury vapour based UVC sterilising lights with a special housing, to sterilise air in a room without exposing the occupants to the 254nm UVC light.

With the evolution and availability of the new era 222nm excimer lamps, Naomi has gone on to design a full product designed to be easy and convenient to deploy in populated areas like medical practices, waiting rooms, retail environments, food preparation areas and live events.

The special feature of the 222nm wavelength is that it is long enough to deactivate viral and bacterial air contaminants, but short enough not to pass through the outer layer of dead skin or the tear-layer of humans.  That means that it is currently considered safe to use in occupied areas.

The filter on the front of the light seems to specifically pass 222nm.  Without it there is a very slight hump in the spectral output at around 237nm.  The filter attenuates that completely.

Excimer is an abbreviation of Excited-Dimer, where a dimer is the joining of two molecules.  In the case of the excimer lamps the molecules are encouraged to bond temporarily in a plasma discharge, and when they revert back to their non-excited state they emit a photon of light at a specific wavelength determined by the chemistry.  In this case it's molecules of Krypton and Chlorine that form brief molecules of Krypton-Chloride (KrCl), before reverting back and emitting 222nm photons in the process.

The process of creating the plasma is very similar to dielectric barrier ozone generators.  By coupling to the gasses capacitively the lamp also avoids contaminating the gasses with the electrode materials.

Note that the unit uses 500mA at 12V (6W) but has a generously rated 12W power supply that runs cool.

This technology looks like it may be valuable in medical, care, travel or social environments to limit the spread of pathogens.

I've been watching some One Marc Fifty stuff on YouTube. I can follow him well, and I'm decent at much of the hardware stuff. At least I can compile OpenWRT or do a basic Gentoo install with a custom kernel. I dread staring at NFTables, but can hack around some. I don't fully understand networking from the abstract fundamentals. Are there any good sources that break down the subject like Ben Eater did with the 8 bit bread board computer, showing all the basic logic, buses, and registers surrounding the Arithmetic Logic Unit? I'm largely looking for a more fundamental perspective on what are the core components of the stack and what elements are limited to niche applications.

I just realized I want to use self signed client certificates between devices. It was one of those moments where I feel dumb for the limited scope of my knowledge about the scale of various problems and solutions.

I've made the effort to secure mine and am aware of how the trusted protection module works with keys, Fedora's Anaconda system, the shim, etc. I've seen where some here have mentioned they do not care or enable secure boot. Out of open minded curiosity for questioning my biases, I would like to know if there is anything I've overlooked or never heard of. Are you hashing and reflashing with a CH341/Rπ/etc, or is there some other strategy like super serious network isolation?

My old man has a bunch of .dox stuff saved. He has complicated large files saved that are not supported by any of the FOSS conversion tools. I've tried Libre office, Abi Word, and every command line tool and converter I can find. These are entire book sized files.

I have a W10 machine with Word. Is extracting the .exe and running it with wine feasible without making an epic mess or massive project of this?

This is something that perplexed me a few years ago with Flash Forth on a PIC18/PIC24/Arduino Uno. I was using the Python serial emulator S-Term because it is simple in the source code and worked. I really wanted a way to load more structured Words into the FF dictionary with bookmarks in a way that made sense structurally. That lead to a desire to execute code from the uC on the host system, but I never wrapped my head around how to do this in practice.

As a random simple example, let's say I set up an interrupt based on the internal temperature sensor of the PIC18. Once triggered the uC must call a Python script on the host system and this script defines a new FF word on the uC by defining the Word in the interpreter.

How do you connect these dots to make this work at the simplest 'hello world' level? I tried modifying S-Term at one point, but I didn't get anywhere useful with my efforts.

You can't copy pasta this prompt. There are a few nodes that are specific to SD3 and required.

::: spoiler EDIT: more proof of the chain that lead to this image. They were not all this good. I'm cherry picking for sure and these are just webp's without workflows attached:

Prompt was through ComfyUI, so it is embedded in the image: https://files.catbox.moe/aiy8p1.png

It was supposed to be a pug kangaroo hybrid but the AI apparently wanted to throw in some monkey too.

I want to extract and process the metadata from PNG images and the first line of .safetensors files for LLM's and LoRA's. I could spend ages farting around with sed or awk but formats of files are constantly changing. I'd like a faster way to see a summary of training and a few other details when they are available.

Felt sexy, needed to share. Not my gen, just one from a NSFW LoRA posted on civitai.
