Our bodies are just big bags of chemicals, and we understand what's going on with only a moderate degree of certainty. Have a solid read of results over at examine.com, I do, often, and you'll realise that even for basic activities like 'growing muscle' there are hundreds of factors, each with hundreds of factors for those. The immune system is even more complex, so, the medical industries monkeying with it is rudimentary at best. Yes, I know, scientists know A LOT and are very confident in themselves, just as 19th century surgeons were as well.

I'm happy to take the vaccine, once everyone else has taken it first (everyone else meaning 90%+ ish). If there are unintended side effects as history has show us has cropped up in countless chemicals introduced in to our daily lives it's better for me and my family that other people more accepting of risk take those chances.

We do have a family friend(~50-55yo group) who took the vaccine(AZ) and was so sick afterwards he could not attend work for 4 days. As a day rate contractor, that was about 5-6k on his pay rate.

I live in a country where COVID is not on the loose, testing and vaccination is free. At present the risk:reward is skewed heavily in favour of inaction.

There is one other thing slashdotters you should consider. Some people, myself included, are FAR MORE LIKELY to do something if we're not forced. The more I'm called out on making a rational decision, the more entrenched I become in rejecting what looks like blind fanaticism or groupthink, irrespective of the subject, all the time.

"Secondly, a solar roof costs an average of $20,000 to install, plus another $10,000 for batteries"

Mostly correct. Three big components.
Battery, 9.5k.
Board : mppt, inverter, controls, etc. 8k
Panels : (Less than $1\w). Lets say 4k-6k depending on needs
Install : 2.4k

All costs are in the past few months, in AUD and in a remote area.

I like off grid, but I can understand people who prefer grid connected zero storage systems. In Australia you can get 6.6w installed for under 5k making electricity for most houses effectively free. Think that through. 5k for free electricity almost forever. ROI here for most households will be about 36 months after which you'd have 27(~) years of free electricity. You would still pay connection costs.

Investing $5k in HYG would net about $19\month. 100% risk free obviously ;)

Somewhat.

I've got my offgrid house finally setup. It's small compared to some, but it;s a 6.6kwh of panels, 10kva inverter with ~10Kwh of battery. Total cost including installation was 30k AUD. I'm still paining the building and have these big 500w lights all about. Each evening I work until I don't feel like it, a few hours. The inverter eat about 5% each night on its own. The Battery doesn't go down much at night. The Battery was about 9.5k of the total. The battery so far is always full again by mid morning. and sits at 100% all day long. I have so much electricity that I use 150w LED pendants in my shed 'for a bit more light' during the middle of the day, the battery stays on 100%. Even with all this heavy use my use has never eve reached anywhere close to the rated 20% DoD. Never even gone under 50%.

Pretty soon my dump circuit will be used to run water pumps, heat the slab, hot water. All kinds of wasteful power uses. I have no lack of spare capacity for about 6 hours per day.

Power consumption at night is a bit more of a big deal on battery. Gas for oven and for heating it's best to heat the building for the evening, then turn it off.

Point here is that some small adaptions can be made voluntarily to halve the cost of a solar system. If I wanted a big aircon or a 6000w oven, the the solar system would need to be double or triple the size.

Most people would probably be ok with some small inconveniences to get 'free' electricity forever. The problem is, most people don't have the ability to build a house with the intent of energy frugality and high insulation, low use of heat bridges.

Big solar and big wind are not seeking to replace baseload. They are merely just profitable ventures. Taking yourself off grid IMHO is the better approach but since replace most of the houses in society is unviable the grid connected people will be stuck with a dysfunctional mess for years. Or, you can opt out.

I worked on a high freq system which tried to beat other market participant. The code was optimized to hell, there was CPU affinity, everything cut down. Short fibre cables, fastest aruba switches we could find, the list goes on. Then we realized we could squeeze a little bit more out of the CPU with immersion cooling, so, put it in to a tank of mineral oil. It worked well, but NOBODY in the team wanted to do maintenance or hardware upgrades on that server.

Yes, the server was colo'ed in the exchange too. Can't believe they even approved that. Our rack was the one with greasy fingerprints all over it. Many employers later, can't say I miss that server.

So, the virus sprang in to existence right next to a bioweapons lab with a spotty safety record in a country with a spotty record in running BSL-3 labs and had accidentally released 'other coronavirus' based research projects like SARS. The Chinese Government never admits to face losing mistakes it can hide, is also expected to be totally trustworthy this time. Then when lab workers admitted to the world what happened they were ignored and apprehended. Why not use Occam's razor here? Chinese government coverup of a lab screwup in a BSL-4 lab, that 'should' have had better operations, but didn't. Also, they may have been working on things they should not have, hence the months of stonewalling while they carefully reconstructed lab records. I mean expecting 'more of the same' is not exactly a conspiracy theory at this point.

Interglacials tend to last 10-20k years. Currently we're at ~12k in to this one. Lets not hasten the march towards ice ball earth by "it appears that we created a cascade effect by increasing planetary albedo in such a way that we can't reverse now that the feedback loops are operating.". Whoops doesn't really cut it. We're going back in to the ice age no matter what humans do, we just don't control enough energy to set the planetary weather (Kardashev Type 1). Geoengineering is probably best conducted on Mars where we can't end out own species due to miscalculations. Can we accomplish this before the interglacial ends? Probably. A few thousand years at the current increasing speed of scientific development is more than enough time for us to hit the singularity. Lets not rush to implement half baked idea's that are not necessary. Global warming(human caused or not) just bought us some time however earth feedback loops are sufficient to dissipate that burst of energy, and fossil fuels just won't last very long (when you count years in the 1000's, it's last like 4-7% of the next 1000 at most. We're heading back to ice ball earth.
