I really do want to learn and love it. It seems I love all the things which are told about it, but, I think JJ has a tutorial problem. I would really want something which focuses on concepts of it rather than workflows. May be some diagrams? I know that JJ-ists think that it is very easy to understand wall of cli printed text, with ascii trees and hash prefixes in bold, but it really isn't. Especially for target audience of tutorials (folks new to JJ).

https://jj-for-everyone.github.io is the most approachable jj tutorial I've seen. I wouldn't say it focuses on workflows, but it does take a "learn by doing" approach a bit more than the "data model first" approach it sounds like you might prefer.

It's still a young tool, it's not surprising that tutorials are a bit lacking (honestly there are surprisingly many for its age). Maybe be the change you want to see in the world and make one? (Which would be an... interesting... way to learn the tool for sure).

The point being made is that if smoothing over time becomes sufficiently cheap then smoothing over space is supplanted.

It would be nice if this happened before the next Carrington Event (or the next nuclear war with orbital EMP weapons.)

I get that, I'm just disagreeing that we should be looking forwards to storage becoming that cheap. Particularly when our cheap energy sources (solar, wind) have a lot of location specific variability over time.

With some exceptions for sufficiently remote (or sufficiently always-sunny and not too dense) places that local grids themselves are no longer worth it

Batteries are probably going to kill long-range transmission lines and open up remote generation at a scale never thought possible. Desert solar, remote hydro, etc etc. As the price continues to fall and the density continues to rise the economics of transmission completely change and will decouple the location of power generation from the use of that power dramatically. This decoupling of location and use will drastically reshape energy production. Right now is likely the time to buy sunny land in the middle of nowhere but near train tracks.

I think long range transmission remains a thing anywhere having a local grid remains a thing (which will be most places for other reasons).

Load-balancing the area having a cloudy few days and the area having a sunny days and the area having a windy few days and so on will remain extremely valuable. It lets you install a lot less batteries and isn't that much infrastructure given that the last mile problems are dealt with already.

Here are some numbers: January 2025, the output of solar was ~1500 GWh, it peaked in June at 10500 GWh. So the lowest output was about 15% of the maximum, this year.

https://www.energy-charts.info/charts/energy/chart.htm?l=en&...

Looking at wind, the ratio between min and max per week is about 1:5 (~1200 vs ~6000 GWh). Just as there is always some solar power generation, there is never no wind, though looking at those charts there were 4 weeks in the late summer of 2023 when production was low consecutively, between 700 and 1000 GWh.

> it peaked in June at 10500 GWh

And 8280 GWh the previous June for those wondering roughly how much of this was due to more solar panels being deployed.

Ok now shift summer sun into winter.

gpm · 2 days ago

Just build more solar. You generate excess electricity in summer and enough in winter. This isn't a problem.

There are different LIPO chemistries. LFP in particular has little problem with being fully charged. You'll see it get swapped in for lead acid chemistries even in places like car/motorcycle batteries.

If you want an Lithium power supply then the keyword to look for is "LFP".

gpm · 2 days ago

And LFP is also cheaper per unit energy and less of a fire hazard. Hard to imagine why you would use a different lithium-chemistry in a UPS.

Correct if I'm wrong, but without any new entrants, the market effectively cornered by a few players and high demand from data centers, how will the prices come down? Just like the GPU prices post COVID and bitcoin demand, how will there be any incentive to bring down consumer prices? The only scenario I can think of is chinese firms catch up and swoop in to corner the market.

gpm · 2 days ago

If demand stays high existing firms will increase capacity to make more money, and then will compete against eachother on price to sell their new extra capacity. They'll do the same to prevent new firms (in other counties or not) from having an opportunity to come into the market and undercut them.

An illegal price fixing cartel could defeat the first pressure on prices (though is unlikely to). The second pressure would exist regardless.

GPU prices have primarily stayed so high because there's kept being new surprising sources of excess demand that the market didn't anticipate. I.e. it has yet to reach "eventually". Also to some extent Nvidia's government enforced monopoly on CUDA (via copyright) has meant they don't have any competitors with equivalent products. And software creates a so called "natural monopoly" because it has zero marginal cost while hardware generally doesn't.

The concept of everyone dying at 40 is a myth/misunderstanding anyways - the reality was a lot more bimodal than that.

gpm · 3 days ago

Eh, here it's more of a simplification than a myth as used in my comment. There are two effects:

1. We've reduced infant (and childhood) mortality. My comment isn't talking about this effect but it did drag down average life expectancy substantially. Including this effect life expectancy at birth in the stone age might have been as low as 20... but as you say the bimodality means this is a deceptive statistic when used this way.

2. We've made it so you on average live longer even if you survive childhood, my comment is really just about this part of the effect. It's still a simplification because saying "on average if you survive childhood you die at 40" isn't the same as "everyone dies at 40" but closer to "adults die at all ages in a reasonable smooth monotonic curve and 40 is about the average age they live to but some get lucky and live to 80 or whatever". But then "don't use ultrasonic dehumidifiers" is like this too, using one won't kill you at some specific age, it will just slightly increase your chance of death every year for the rest of your life however long that ends up being.

The number 40 was picked out of a hat, too. It should be right for some areas at some times just by coincidence though and since I was non-specific that makes me right ;)

How did we survive the last 3.5 billion years?

gpm · 3 days ago

We didn't have access to modern technology... like ultrasonic speakers?

Also we died at a young age. Everyone dying at 40 isn't incompatible with the species surviving but it's what advice like that is usually trying to avoid (and even less extreme outcomes).

I don’t understand why you would have a logging microservice vs just having a library that provides logging that is used wherever you need logging.

gpm · 3 days ago

Logs need to go somewhere to be collected, viewed, etc. You might outsource that, but if you don't it's a service of it's own (probably actually a collection of microservices, ingestion, a web server to view them, etc)
