Subsides are common for all forms of electricity generation, but LA’s 2019 1.997c/kWh power purchase agreement is hardly the far future. https://www.pv-magazine.com/2019/06/28/los-angeles-seeks-rec...

Anyway to use a specific example Capacity factor 26.6% (average 2015–2018) https://en.wikipedia.org/wiki/Topaz_Solar_Farm.

Bulk panels are $0.29 per W or 290$ per kW. PS-P72-330W https://sunelec.com/

If 1kw is worth 0.01997 $/h * 24 * 0.266 * 365 * 20 = 930$. Of course they don’t instantly break exactly in year 20. They lose efficiency over time so averaging ~90% over 25 years which is ~100% over 22 years. https://sunelec.com/wp/wp-content/uploads/2020/09/P72_outlin...

I can’t find an exact breakdown of costs spent on panels vs interest, instillation, inverters etc. But, at most we are talking about fractions of a cent worth of subsides to hit 2c/kWh.

I LOVE the way fish handles PATH. I just modify the $fish_user_paths variable (which is a universal variable) and I don’t have to modify any config files.

E.g. to permanently add `~/.cargo/bin/` to your PATH just do

set fish_user_paths $fish_user_paths ~/.cargo/bin

Not a browser-based app. It was an extremely customized peoplesoft. And the whole project ended in a lawsuit. We had learned a bit, so we took our time to get our duck in a row, and it was about 4 years before we started fresh with a different vendor.

Was that project worth it? We didn't have much choice. Our old ERP was close to 35 years old, and no longer supported, so we were paying large sums of money just to get annual compliance updates for state & federal requirement. The new system is fine, does what it needs to do, but it's a monolithic ERP system: It does just about everything, but it's mediocre at all of it with most of it's tech perennially 4 to 7 years out of date with the best of breed. So, in the areas where we really need best of breed, we bought that and integrated it into the ERP, which is considered the "system of record". So it's fine, it works, I guess. The real kicker though is that the system we ultimately chose, while not an Oracle product, still required an Oracle DB. Fortunately we don't actually deal with Oracle as a vendor though. Our vendor is basically a VAR.

The person likely is dual income. So, it might only be 3x their household income. Which is perfectly acceptable.

Getting a home for 2x your household income is basically impossible in this day unless you’re one very lucky remote worker who enjoys living in the middle of nowhere.

I’d say the upper threshold of 4x your annual income is where you’d likely want to throttle back. Any higher, you’re in very high risk or can’t afford it. But trying to get a home for below 3x your income? Basically impossible for most people.

Any drug dealer will tell you "Don't get high on your own supply". It is good business.
House prices don't really go up; land prices go up.

Land prices go up because the desirable land (land given value by its qualities, whether inherent or through value added through improvements) becomes more desirable.

Land prices also go up when money is cheap (low interest rates), as do other assets. In those circumstances, house prices (the house, not the land) will depreciate slower than usual because having a deteriorating house is better than having cash.
This is where I tend to gravitate. Even using ActiveRecord, what people consider the “ultimate” ORM, I still find it gets in my way. None of my colleagues write SQL queries, it’s all completely abstracted away behind ActiveRecord, and we are constantly running into issues where someone forgets an `includes` and we end up with an N+1 error. N+1 errors are so easy to slip into with an ORM, it’s pretty much one of our biggest performance issues.

This seems like the biggest trend the more I use RAILs: it’s great to iterate and prototype, but as soon as you hit scale the maintainability becomes a big issue. I’m not saying other web frameworks are immune or that this is a problem that cannot be solved, it’s just all of these abstractions and cascade of configuration objects to make RAILs do what you want end up getting in the way.

A query builder is the best of both worlds: semantics that resemble raw SQL with some ability for composition.
You say that as if a meter will not have catastrophic impact on the world.

'use low energy software' isn't that simple

me just being a person in the zoom era uses a combination of a windows gaming rig, an old mac for video conferencing, a new mac for xcode, and a linux laptop so I don't hate myself

the best tools don't work at all on old hardware. your time isn't free

we would need to legislate open APIs for every commercial service before it would be reasonable for tech professionals to use old stuff

only open source can work on old hardware

The thing is, though, that you have these conversions even within the imperial system (https://en.m.wikipedia.org/wiki/Imperial_units#/media/File%3...) but not within the metric system.

My experience with U.S. students is that they are having a much harder time making sense of the imperial system (that they are used to) than doing problems in metric, even though they don’t use it in everyday life.

I came here to point out nuclear and fusion also. Lets say you can get the energy cost to near zero, the the 200+ euros left per meter sq could be cut down by looking for construction or scaling efficiencies and even the fact that if energy is near zero from nuclear or fusion power, it might end up lowering construction costs if it can be diverted into use in heavy machinery. I'd love to see this same experiment powered by a small Thorium prototype reactor.
Ask HN: What is the biggest monolithic app in a VM/baremetal?
There are plenty of debates and talks about monolithic vs microservices touting the benefits of each. Most such talks seem to indicate that monolithic apps scale badly. By that they probably mean horizontal scaling && developers/teams scaling, but we have good options for vertical scaling these days via monstrous VMs with high RAM/CPU from almost all cloud providers.

What is the biggest (scale) application(s) that you have personally seen or worked with in a single VM or baremetal server ?

The scale could be in terms of maximum requests per second, volume of data transferred, maximum parallel connections, etc.

The most popular example that I could think of is Expensify where they handle 4million qps in a single monster machine with 1TB RAM via Bedrockdb https://blog.expensify.com/2018/01/08/scaling-sqlite-to-4m-qps-on-a-single-server/

I am looking for similar examples of big products on a single machine or VM. Not on a super-computer, mainframe, specialised appliances (like SAP HANA), etc. but normal X86 boxes or cloud VMs. I am curios to know how much of HN crowd choose these over complex things like Kubernetes and their thoughts on these.

> that no one in Texas (of all places) would rather freeze to death than willingly accept the risk of being frozen to death by a tyrannical government that promises things then breaks promises

These are the exact same pathology. You're drawing a distinction based on whether one is "government", but they're the same type of lethargic entrenched entity, regardless of how they were chartered.

The actual problem is the lack of accountability. The free market philosophy points us to exit as an ideal of accountability. Sometimes exit works very well - switching electric providers during quiescent times to get pricing that better matches your usage. And sometimes relying on exit fails terribly, like this rare event where it is easier to balk at obligations rather than have prepared enough to fulfill them. If we care about exit in general, then it behooves us to recognize when it fails.
>Socialism creates another bunch of perverse incentives

And capitalism creates other perverse incentives, such as middlemen all trying to get their cut of various fees, charging rents, building competitive moats, obfuscating the paperwork so you can't even figure out what basic services cost in advance... kind of like the health care system currently in the U.S.

Part of the issue is that the insurance pool needs to include low risk individuals to work.

If everyone under 30 says “I won’t shell out for private insurance, and if something catastrophic happens, fuck it, I’ll declare bankruptcy”, the system falls apart for everyone. Unpopular as it is, this is the logic behind the ACA mandate.

It’s a terrible outcome, unless you’re rich enough not to care about insurance to begin with. You get coverage that’s unaffordable for higher risk people who need it, and uninsured “healthy” people one stroke of bad luck away from disaster.
They are a sketchy company, from the over-zealousness to defend their "IP" to the price they demand for their yearly software, to the creepy vibe their articles about young female players have. So no sympathy from me, go stockfish.
It's not really about "productivity", it's about "wasted time". To be clear, I don't consider idle, leisure, even completely bored time to be "wasted". In fact, my favorite vacation is generally cruising because (1) they give you a menu of things to you can do that day, you pick, you don't have to think. (2) it's mostly pre-paid so budgeting is easy and (3) it's generally easy to find a cruise where it's expensive/impractical to have any internet service allowing me to completely disconnect.

Wasted time is "I have a handful of really low priority things that I'm never going to do so I'll look at Netflix and see what I haven't watched yet". For me, though, it's a bit more than that. Our budget allows us to live just fine, but with what amounts to very little work, I can literally take my family on a vacation about every two months.

Before eye-rolls abound, we travel extremely cheap -- I'm talking week vacations, family of 6, under a grand. And I decided a long time ago that my priority with my children would be to put my money toward memories rather than "crap". We've had gift-less Christmas's in favor of a (way over-budget) vacation[0] more than once and we'll probably only do it that way from here on out.

Given a choice between channel-surfing-Netflix, which I get plenty of (and I think a lot of us find ourselves in that spot) and driving around to places in my local city that I haven't been before (and it's surprising how many there are), I'll take the extra paycheck. Honestly, I'm nearly out of things to repair/improve in my home with my spare time. There's still a whole lot closed down up here.

[0] Partly because of that, we have a hard time when we aren't planning a post-Christmas trip. Our kids don't want much. I mean, they have basically everything in the palm of their hands from Apple and Gooble, as it is. :)
This question is probably better answered in hindsight. It's probably easier to look back and see who was the top insightful thinkers of their era throughout history. Some of the top thinkers of today might be having their ideas dismissed and will be found out later to have just been ahead of the time. But to take a guess I would say people like obviously Albert Einstein, Elon Musk, Vaclav Smil, Stephen Hawking, maybe people like JRR Tolkien, George Orwell, Jordan Peterson (before his chemical lobotomy), Tony Robbins purely from fame and attention. There's probably people who are much more insightful thinkers that no one has even heard of. Heck it could be someone totally unknown who just reads books and ponders things all the time.
Ask HN: No-Framework Responsive Design?
TL;DR: Any suggestions for learning responsive web design without any special frameworks?

I’m a python SW engineer with a basic understanding of HTML, CSS, and JS, and I’m looking to learn responsive design. I’ve seen JS frameworks come and go so quickly that I’d like to buckle down and learn more fundamentals of CSS and vanilla JS that don’t involve SPA frameworks, React, Angular, SCSS, etc.

I’ve used Bootstrap with Flask, but Bootstrap doesn’t offer enough control for my liking.

So, I’m trying to seek out any learning resources that don’t rely heavily on a superset of JS or CSS and instead focus heavily on web standards that work across browsers and platforms.

I’ve seen MDN and W3Schools, but those are mostly a string of disconnected docs. I was hoping for a more cohesive course or book / video series.

Any suggestions welcome, and if I’m going about this the wrong way, don’t hesitate to tell me.

What are you hoping to prove with this? In terms of what they are actually doing, it sounds like they're installing a lot of renewable energy. Indeed, more than most places. Do you also expect the Texas government to bust into oil and gas company headquarters and force them to say they believe in global warming?

What does it matter who believes what if the real things that are actually happening are that they build a lot of renewable energy sources?

Heroin overdoses are largely because of quality control issues that stem from criminalization. The drug is frequently cut with adulterants, and people shoot up because it's the most efficient way to use it.

If heroin was legalized, it could be standardized at a non-variable purity, and other methods of intake would be more popular. Lots of people were going blind from alcohol consumption during prohibition also.

> (usually people writing dumb code without realizing it's expensive)

Some years ago, one morning I gave a co-worker a recommendation on how to improve a loop that was unnecessarily hitting database through the Django ORM. He committed the fix that afternoon. Barely an hour later I accidentally reintroduced the exact same slowdown in the exact same loop when adding a different piece of data to it.

Soooo yeah, ORMs can be so simplistic it's too easy to do by accident even if you know exactly what's going on under the hood.

I suspect they're listing maximum power draw and not mining power draw like their other cards, otherwise they'll also be outer performed by their normal cards if properly optimised.
Other grids certainly could do even more to harden their power systems against extreme weather events. But Texas is clearly suffering the worst and most prolonged outage of all the states during this cold snap.
It really depends on what you run though.
Does that make the conclusions reliable?

I'm not sure why you want to use layman as a measuring stick.
Strongly disagree. Whenever you borrow money from someone, you start paying interest until your debt is repaid. On the global scale increasing debt means that more and more people are using someone else's money to accomplish whatever projects they do. Or that a larger an larger chunk of our economy is interest paid to existing capital holders that made money in the previous cycle and are not passively collecting rent from it.

If you compare it to the housing market, it's like seeing that more and more people move from owning their property to renting it, increasing the divide between the landlord class and the renter class. In the long run, this just brings more social tension, kills social lifts and ultimately brings more unrest.

I don't buy it. How do you define "standards of the day?" The worst of those at the time? The median?

There seem always to be people of the day that are in direct opposition to what you call the standard. As an example, Quakers and other abolitionists of the antebellum South famously aided slaves to escape to freedom via the "Underground Railroad".

Was anti-slavery the standard of the day? Or were the abolitionists progressive? Enlightened? Or were the slave-owners (the Millikan's) regressive. Provincial?

I think it's hard to say what the "standard fo the day" was. Maybe a historian can answer.
