> Ice storage air conditioning is already a thing in some places to take advantage of cheap electricity at night,

Most of South Asia still relies on ice for air conditioning, and food storage, and that hasn't changed in a century.

Why? People there only buy it for a few weeks in a year, during extreme heat, or when they slaughter livestock to preserve meat.

It's not yet economical for people to put few hundred dollars into an appliance they use few weeks in a year.

A lot of places may not even have electricity there in the first place.
I find it interesting that you position this guy as a "hero" with supporting arguments being that he brought failed legal action against someone else for calling him a name on twitter, while implying the reason he lost was because the hero chose to hire a crazy lawyer. Then say he's clearly a hero since the lawyer he chose has opinions about things you don't personally agree with, as if that has any relevance whatsoever to the legal case here.
For starters, it's almost 30ct per kwh here. But admittedly I don't know what they pay being at 12k employees, size-wise. Most of these computers are being used for mundane office jobs, so I'm fairly certain idling is what these machines do for most of their life. As for performance, I'm still running a third gen i5 at my job from 2012 and actually doing dev work. It's still doing just fine. I think I'll upgrade this time, but I skipped the last 3 models out of laziness.

I really want CSP to succeed for no other reason than I find it much more exciting from a childish mechanically fascinating point of view.

However, all indications at the moment are that solar + lithium storage is winning this battle. We are seeing larger farms with more installed storage every year.

Perhaps CSP might flourish in certain niches, particularly those where waste heat and / or industrial high temperature processes are required in addition to electricity production.
Thank you. I have added a note to the article with your correction :)
Yeah, it's more of a manual merge.

Long time I hadn't that much of a laugh browsing HN.
You are half right in that solar doesn't provide base load (obviously). However, other renewables do. E.g. offshore wind is pretty reliable and geothermal and hydro are pretty decent too. And storage seems a more economical alternative to having gas-peaker plants and is commonly paired with solar. Having all of that seems to be a winning solution for many countries that never had much nuclear to begin with and that are shutting down remaining coal and gas production.

Germany's energy sector is dirtier than France because France has a lot of nuclear power plants left from mid last century. And Germany of course built a lot of coal plants during that time and never had that much nuclear due to the political sensibilities of that era. Germany has invested a lot in early and relatively inefficient solutions over the last few decades. As these are being modernized, their cost will gradually improve. E.g. wind turbines from last century are a very different proposition than a modern 15MW offshore turbine. So yes, Germans paid a price for being early but they now they have a thriving industry that is about helping others switch to renewables.

Many coal plants in Germany are being shut down until 2038 and most of those French nuclear plants are reaching their end of life pretty soon as well. France has actually been decommissioning old nuclear plants for a while and has been gradually shifting to other renewables. E.g. wind and solar are growing relative to nuclear in France (quite a lot actually). Of course the issue is less urgent in France as they have (mostly) clean production already. But proportionally, nuclear is becoming less important for them.

Both France and Germany pay too much for their power. Solar and wind can be cheaper than that. That's actually what is driving these changes and that's the point of this article. It's not just a little bit cheaper but massively cheaper and still getting cheaper. We are talking orders of magnitude here (plural long term). Enough that you can consider some pretty wild solutions to address the base load issue and still end up with an overall cheaper solution.

New nuclear plants to provide base load don't make a lot of sense economically when that is true. This seems to be what you are implying. France is of course still building some new plants and they are deploying wind and solar too. They are doing more of the latter and less of the former however. The net proportion of nuclear is actually decreasing. That's true for most countries that are still building nuclear plants: they are increasingly less dependent on those plants. Like China, the USA, etc.

That's because the base load argument is simply wrong. Neither nuclear, coal, nor gas are long term needed for that. All of those are unattractive from a cost perspective long term.

I have an apple account with two different passwords. That work simultaneously, but on different services. The only way I figured this out is I evolve passwords with a numbering scheme; I kept forgetting the password, resetting, and incrementing a counter. I slowly realized I wasn't forgetting; it's that I had multiple passwords live.

I tested this as recently as 2 months ago.

That is exactly what the solar panels do. They aren't mounted directly on the shingles but offset a couple of inches from the roof. The area under the panels tends to be cooler than the rest of the roof.

Egypt's fertility rate has as far as I can tell dropped every year but a handful since the late 1950's:

https://data.worldbank.org/indicator/SP.DYN.TFRT.IN?location...

To suggest this implies some cultural resistance to reducing fertility seems to be fundamentally flawed.

It also doesn't really work like that - even countries with a culture that involves favouring large families see fertility rates drop as they develop.

This is not a "meme", but a simple observation from data that show that it has happened consistently to every developing country - including Egypt. What you can not do is assume it will happen at the same rate everywhere.

The world is full of gradients but also binary (aka black & white) systems. Charge is binary, computers are binary, life and death are binary. Systems can be either binary or gradients if one person believes something is binary or discreet that's his opinion and it's not automatically wrong.

This assumption that gradients are everywhere/ubiquitous/superior is not correct.

No wait let me reframe what I said.

How is it that someone can exist that can't comprehend the fact that many things in the universe aren't gradients and that they are in fact black and white? That is SO perplexing. It's baffling to me how someone can think like that and basically walk up to someone and examine them like some sort of sub human and announce that this other person is so perplexing because they don't think like them??

Like how come these people don't announce these things in public? They don't go to someones face and tell them that their opinions and behavior is so baffling? Why? Maybe it's because most people are aware that saying something like this is offensive. So they save it for HN where they can announce this garbage all the time without retribution from the other party.

It's just so perplexing to me how you, daniel, are unable to comprehend this. You say these "black and white" people are everywhere. Do you walk up to them in real life and tell them how "perplexing" you think they are? No. You don't. But you probably do it all the time on HN. So baffling this behavior.... I mean your not necessarily just plain old dumb and you aren't uneducated... yet you still do this on HN and can't see that it's an insult on HN just like it is in real life. So baffling that a human exists that thinks like this. I am truly perplexed.
Thank you so much!

Zulip is a really nice tool and a favorite of mine too. It's already on the list for tools we need an integration for.

Pricing is really hard. We aimed to make it as transparent as possible and tried to make it more attractive by only billing for active users. Maybe we could enable something like 'confidants' who can view decisions but aren't billed? Though if someone doesn't really interact with the app but just looks at decisions they aren't billed anyway. Really difficult, or maybe I just don't see it (yet)? Maybe you can elaborate what you would like to see there?
If you have something you want me to understand, please explain. I'm happy to listen to what you have to say. Like everyone else, I'm not perfect, sometimes I don't understand things and I need some help from people like you.

In the language of differential forms, a probability distribution would be a form of the highest order (dx ^ dy ^ dz in three dimensions), and f would be your typical map between manifolds. It would then receive identical treatment to a density, because in a sense that's what PDFs are - densities of samples in the limit of infinite samples.

It is hardly sloppy, the author just wrote it in the language of vector calculus. Another treatment, the one in my textbooks, addresses it with the determinant of the Jacobian matrix from the perspective of change-of-coordinates in multidimensional integrals. As always there are as many ways to skin a cat as there are closed curves on the 2-sphere.
> We are seeing larger farms with more installed storage every year.

Same is happening with CSP, just way less so in the US. CSP with MS storage is already cheaper on a LCOE basis than nuclear, esp factoring storage [0]. Lots of PV analysis never includes storage costs (and for obvious reasons).

I think Li tech is probably better served for individual consumer applications (because of all the constraints) than at the grid level.

In https://twitter.com/kuenzler/status/1397814747379154944 (German), Fredy Künzler from init7 talks about PON and why init7 is opposed to it.

He makes the calculation that from the ≈3000 CHF needed to connect a location with fiber, only 50 CHF difference come down to PON or AON. The advantage of dedicated lines (for all ISPs, too!) overweighs the financial savings in his reasoning.

Another good tip is to use Direct Attach Cables (DAC), which have a much lower power consumption and save you the cost of 2 fiber optics as well. This only works on short distances of course, but between the MikroTik and a few devices that might very well be the case.
> It should be very easy to merge accounts.

This can not be further from the truth. It is extremely difficult to do this. Anyone who says this is easy does not understand how difficult it is to do this across a modern distributed information system. Most services do not do this, because it is so exceedingly difficult, not because they don't want to.
I think this depends on what the ads are being used for. Majority of ads I see are for church services, or long rants on a particular religious topic by individuals who aren't selling anything. Most of my religious ads are not part of a big marketing campaign.

Centrist or progressive churches would also benefit from telling people what time services start. And some progressive Christians would want their opinion piece or podcast promoted. I'm sure those ads exist. I just don't see them very often.

For ads of this type, we're not talking about expensive bids. These fall squarely into the "$20 to promote this post" category.

This is very impressive. I’m in the midst of implementing an outdoor hydroponics system in much the same vein, except I’m mostly rolling my own sensors using arduino and LoRa for comms, as we are really distributed here - the pi running openhab which runs the show (not just the hydroponics, but energy production and routing, tank levels and pumps, river level monitoring, weather station and generic drip irrigation) is hundreds of meters away from the garden. Finding sensors that weren’t expensive or didn’t require hardwiring was a pita, so just went for very generic modules. Ultrasonics for tank levels and river levels are my favourite so far - something really neat about being able to measure depth without contact, and the modules cost me €6 or something crazy. Commercial gear was all the better part of €1,000 for the same function. It’s all a load of work, but it’s a lot less than managing the homestead by hand.

As I’m still in the midst of implementing - I have the physical end largely done, sensors mostly made, logic roughed out - I’m definitely going to be working through his article looking for gotchas.

I’ve gotta say, I am curious as to what drove him to build his own platform to run it - openhab works great for home automation stuff, even complicated home automation stuff — and grafana+influxdb give great insights.

I digress, but I’m literally trusting it with my life these days, as I’ve built a flood EWS around it - we live on a river that, once in a blue moon, goes crazy - but predictably so - so a simple model around the delta and double delta of level change and precipitation rates (both from our weather station and the one other weather station in the drainage basin with public data, as well as weather forecasts) tells me when it’s time to bug out, and when it’s time to just enjoy the sound of the rain on the roof and the rumble of the river. It proved itself gratifyingly accurate this winter. The river started to look scary, the weather was dreadful, and I was giving only a 5% chance of a flood entering the house - less than 1% of it being a dangerous flood. Evacuated anyway, as I didn’t trust it at that point, but we didn’t flood, and the peak level was within 5cm of forecast. Really short drainage basin makes the river dynamic but very easy to predict.

So yeah. Openhab. Super powerful for this kind of thing.

> How else do you interpret this but racism:

While the way it is phrased might not be perfect what they are saying still holds true. According to them Egypt has a very low scientific output, far lower than it should have.

Of course scientific output isn't everything. These Egyptians might be using the water and resources for something else other than science. But none the less, from a global standpoint that doesn't help "us", as in the world as a whole.

If the water was redirected to other nations these nations might increase their scientific output more than that of Egypt goes down, which means it's an overall win for humankind.

To address your second point about religion: Is it really? A lot of religions advocate for having many children. Christianity as well. While of course it isn't the only factor studies[1] show that religious people have more children.

So let's recap:

* The commentor claimed that the water might be more use to humankind as a whole if it is directed to another nation that might raise their scientific output more than that of Egypt will lower. This is questionable because it doesn't take into account other factors like production of goods. But in general it holds true, humankind as a whole gains the most by having water used as effectively as possible

* The commentor claimed that high birth rates are a result of religion. Once again this isn't a black/white matter. Religious people do have more children. Islam or Christianity, it doesn't matter. As such I would not call this in any way racist or islamophobic, though of course we are missing sources to know if this is actually the case. It might be or it might not be, but claiming it is definitely not the case and pulling the racism card is even more nonsensical as it discredits a possible, though not validated, option for why birth rates are high.

Their definition of successful targeting is different than yours. Back in 2019(?) Google published average display ad click rates of 0.03% I think. If FBs targeting gets them to 3% (100x better), that’s hugely valuable to them, while you still see mostly non interesting ads.
Linux "won" because SGI very loudly shit the bed and betting on Itanium, taking IRIX with it, DEC was in the process of making the future of Tru64 very confusing with the Alpha, a computer that didn't support their flagship OS, and HP was EOLing HP/UX because they bet everything on IBM's OS/2 Warp.

The only big UNIX vendor left was Sun Microsystems, and Solaris indeed dominated the 90s dotcom era. Everybody was running SPARC and SunOS servers.

It wouldn't be until the mid 2000s when Linux started picking up the pieces left behind after Red Hat started their server product and certification program.

For a long time, Linux was strictly a hobbyist OS. It later dominated by simply being the last one standing after everyone else fell.

It starts with a claim that is fundamentally false, though: the suggestion that Egypt's fertility rate is not dropping.

I hesitate to call it a lie, because it could simply be that they have not looked up the numbers. But it is questionable when they took time to look up a population pyramid but neglected to look up the actual fertility rate over time which would have immediately invalidated the central pillar of a comment that then went on to assign blame for a falsehood.
