I am very much a DIY'er and doing my own HVAC repairs have never been out of the question. Actually, I have rebuilt a couple of systems, less the pressurized parts of the system.

HVACs are great until they aren't and the need for repairs always comes up at the worst possible time. It would be nice to know more details for those reasons.

If you ignore the direct question about charging an HVAC, there could actually be a small, slow leak in my system as it stands. That'll get troubleshot in due time. (Still, I don't think I have ever had a system that didn't need the system to be topped off after a few years, even with no detectable leaks...)

It doesn't seem difficult: Ensure system is at correct temperature; attach a gauge; depressurize/pressurize as needed.

There has to be some "gotchas" in there somewhere. The equipment is cheap enough and I am fairly sure I can source the correct refrigerant easy enough.

Aside from needing to store and manage a small supply of refrigerant and that there are some annoying risks (like a system freezing over, etc..), what cost factor and equipment am I not taking into account?

I am fairly sure that I am being laid off with other Sr. Engineers tomorrow and need some ideas. Basically, I saw a calendar mistake by HR, so oops!

Meh. It's gonna suck for a bit, but whatevers. Life is more important than a shit job. :)

I just stumbled across this beast that was previously owned by a Russian sniper. It's got characteristics of an F-17 but it looks like the stock as been drilled out in places (or replaced) and I am about 60% sure that those are Vortex optics. Any ideas?

When browsing on lemmy.ca/c/all and I click through to a post, the local source instance and community for a post is shown as lemmy.world/c/hot. The source instance is something completely different and shown in the post info bar below the title.

This can get awkward when I think I am commenting on a post I think is on lemmy.world or lemmy.ca when it might actually be lemmy.ml.

Highlighting the source instance a little better would be super awesome.

Edit: The above Connect filter only works for title posts. It doesn't seem to filter comments or community names.

I mention this only because of some questions here and how people are going to the effort to censor out comments on this post.

Oops! I actually ment to post this in a ham radio community. RF is still RF, so it kinda fits here if you squint a little bit.

Tectonic activity bends rocks all the time, even hard ones like granite. That takes a ton of heat, pressure and time. It also makes sense that in the right conditions, sheets of rock simply don't have the room to shatter so they must bend.

Have we been able to do the same in a lab and would it have any commercial use? Bending a random bit of hard rock would be an interesting novelty, for sure.

I am creating a simulation to evolve simple, multi-cell organisms. (Just for fun!)

Neural networks are fairly easy to evolve, even more so when it's done by random mutations and not actual training. Build an ANN at random and introduce mutations with every generation. The ANNs that accomplish simple goals (by pure chance) live to duplicate with every evolutionary cycle. Fairly easy stuff.

I am stumped when it comes to creating something that would simulate the genes that represent a body. After some reading today, there isn't much info on how cells form into specific shapes for arms, hands, organs, etc. (I am sure there is a ton of data, but I don't know what subject to Google.)

Genes can create the patterns for specific chemicals and cells. How to cells then develop into functional body parts? What makes a heart the shape of a heart?

I think that having a better understanding of that concept can help me develop a framework for physical evolution, even if it as a very tiny scale.

(Putting the ANN in charge of controlling those different body parts is also easy. It's just a matter of allowing those physical traits to evolve first.)
