Right, the heat pump will reduce energy use to maybe 1/3 of a gas furnace, but natural gas is something like 6x cheaper for the same amount of energy, so it is an expensive folly.

If California is serious about this, they need to reign in the utilities to reduce prices and or stop the attacks on solar installation.
This is interesting, because it seem to be a start at solving the Fulmar Problem.

A fulmar is a cliff nesting sea bird (with a defensive habit of noxious projectile vomiting). They spend their early life on a ledge, but one day they have to start flying. And if you are a fulmar you have a very limited time to learn to fly.

So the question is, how does a baby fulmar learn to fly in 10s!

It would be interesting to know how much computing power is required for training (compared to the power reqùred to run the controlling NN).

My own view is that the network architecture is important, so fulmar brains have evolved with a neural architecture that enables extremely quick learning to stable flight.

I played around with a few ideas on using GAs to evolve NN architectures for rapid learning during my PhD 25 years ago, but ended up going in another direction.
> I haven't been to Africa or the Americas, but I'd say from my perspective, that things in the US are just extra large.

That's probably it.

I've also been to New Zealand, and everything was smaller there too. Though still not as small as stuff in Europe.

Cars are where it holds the most true. I told my American friend we're thinking of getting a Mazda CX-5. His reaction was, "why so small?"

I told my Portuguese tutor I was considering the same car. He asked why we needed something so large.
Of course, but that's all pretty clear cut (at least in this example) and well spelled out in the retraction.
that's correct. they speculated -- they're economists, not sociologists -- that it was about status, hours, lifestyle, and the get-rich hail-mary long-shot potential.

workin McDs or Kinkos is eating shit every day, wearing a uniform, etc. and is fundamentally emasculating when compared to gang culture.
The downward pressure depends on where you're sitting. Here in Kentucky, being able to pull in a FAANG salary that's based on the cost of labor in Seattle is a huge upswing in salary.
This is simply how foveated rendering works. Nothing is broken here.

It's an optimisation technique that is needed now because we don't have the resources to handle the full resolution. But this will change over the coming years.

For now maybe just increase the font size on the spreadsheet.
I hear what you're saying here, but I like to delay going in the second direction as long as feasibly possible.

In theory, the idea that "people can specialise where appropriate without having to understand the whole thing" sounds good. In reality, so many, many, many bugs and piles of technical debt pile up from developers with a worms eye view who don't understand how the whole system works. Eventually you have to make this compromise, but resist it as much as you reasonably can, and always strive to grow developers so they know as much of the system as they possibly can.
Has anyone found a good way to control all the features of a heat pump with home automation? I’ve been lookin at Daikin and Mitsubishi but Daikin no longer has an open api and I don’t see much on Mitubishi. It seems like every heat pump comes with its own proprietary remote, and the thermostats and Wi-Fi modules (if available) don’t integrate well.
They are not. We just killed all the fast-moving formats in favor of the internet.

Books about new things were always outdated before they got distributed, and information circulated in magazines, booklets, journals, etc. We got a short time window when books became faster, and people tried to use them that way, but as the experience showed, fast books are still not fast enough.
I appreciate your objectivity, these are not the most usual things to say.
Building codes are much more than you think. At least in Europe there are codes for accessibility, dwelling design, room height, utility rooms, mechanical resistance, stability, hygiene, environment, noise levels, general safety, energy management, sewage, power, even bathrooms must be done by certified people.

All those above are just few and general top-hierarchy of a forest of rules.

Yes, those are all important and good for you, BUT all that add up to the cost for the actual build.

The land itself that is to be developed has to go through a long line of expensive processes, tests and certifications. Investigations to ensure that there is no disturbing bird nesting areas, or too close to small streams that may have rare species.

Again, all that is good, but cost and will drive up the price of the final product.

I've a relative in construction, and he notes that margins are so small it doesn't make much sense for all that effort when there are other options.
Different PoS chains will have different characteristics, but I was curious about this claim so I dug up some numbers for Ethereum, Bitcoin, and Visa:

Transactions in 2023:

Bitcoin: 174310000
Ethereum: 583530000
Visa: 212600000000

Energy consumption:

Bitcoin: 167.8 TWh/yr
Ethereum: 0.0067479963 TWh/yr
Visa: 197.57 TWh/yr (2021?)

Energy consumption/tx

Bitcoin: 962.652745 kWh
Ethereum: 0.011564 kWh
Visa: 0.929304 kWh

It's entirely possible some of these numbers are wrong or off so please check my math, but it looks like Ethereum is the most energy-efficient of the 3 on a per-transaction basis, maybe an order of magnitude better than Visa.

Bitcoin on the other hand is 3 orders of magnitude worse than visa on a per-transaction basis. I suspect both Bitcoin and Ethereum also transact more value in USD per transaction (if you're willing to consider funny crypto money at spot prices) on average, than Visa, by virtue of them having a much higher transaction fee which is also borne by the address making the transaction.

If you don't consider Ethereum transactions to be "effective work" than this isn't a relevant metric of course, but I'm curious how you're arriving at your figure.
Nobody's saying "apt is fragile." I used it as an example because it's the install command I'm familiar with, and the one I see most often in Linux install instructions. Ubuntu's popularity made it the default package manager when outsiders think "Linux."

One aspect of that mob mentality: You skipped past having evidence and reasoning for that assertion; it's just assumed. And then you act out in anger that anyone would question the mob's assumptions.
If you reduce it by 50% you save 50% waste. If you reduce it by 75% you save 75% waste. You dont' have to entirely wipe it out to save a lot of waste, just make it harder and/or more costly.

Attack the supply side, attack the demand side: tax it, regulate it, cap it, replace it. All of these can reduce the mining so they are all useful.

edit: to answer your idea that they will just move...

If these other places were as good or better for mining than where they are now, they'd already have moved. If you make them move to a worse mining situation, that's just proof that what you're doing is working.

I guess it depends on whether you believe capitalism and that "invisible hand" stuff is silly.

Those are good things. I want the autonomy to buy the best-for-me (safe, compact, rugged, beautiful) user experience possible, but I'm very happy that there's market competition (Fairphone, etc.) for customers who want the phone equivalent of a project car.
How? It's $0.52/kwh here, and before that rate increase, we were paying (edit) $278/mo in the summer for similar (70 year old 3 bedroom house), and slightly lower temepratures.
Show HN: I built a contest based video discovery platform with no algorithms
I'm excited to share with you my latest project, Curatrs – a video discovery platform that's challenging the norm. Unlike platforms driven by complex algorithms, Curatrs takes a fresh approach by centering around contests and genuine user engagement.

Why Curatrs?

Ever felt lost in the sea of algorithm-driven content (Tiktok FYP, Instagram Feed) ? I did too, so I built Curatrs.
Now we just need a similar package to smudge and blot the signature slightly, and add a little ink spatter, for the fountain pen look.

Every home in America should have a Heat Recovery Ventilator. They are extremely simple mechanically, yet because of their rarity they are still way to expensive to justify the cost instead of just opening a window. Policy could help a lot here.
Yes, HVAC contractors in the US massively overcharge.

I saved ~ 10k doing the install myself. The equipment is inexpensive, labor can be upwards of 2x equipment cost.
I also recommend the non-fiction physics book “The End of Time” by Julian Barbour. It explains these ideas directly, and inspired Stephenson to write Anathem.

Weirdly, I happened to be reading all 3 of these around the same time, not initially realizing they were connected.
Quite a few lighthouses have this characteristic, it’s usually one rotating light, and coloured glass for the different sections. The idea is that you can safely approach the lighthouse in the “white section” only, the others are for guidance: green to your right and red to the left (at least over here in Europe where we use IALA A, in America it’s the other way around). When you can see white, it should mean you have a clear way towards the lighthouse. Then, as you get nearer to your port, you get again a green light on your right and red on the left, and that’s the right way in.

As for where you’re with respect to any light, what you need is chart and compass. Usually there should be only one light with a certain characteristic in the area, which you can then track down in your chart. With a compass you get a bearing, and you now know you’re somewhere on a line. Find another lighthouse (or other landmark), get the bearing, and you can know where you’re fairly precisely!

I don’t think this will ever improve significantly (maybe a little bit with software tweaks) on AVP1 hardware.

The current algorithm is not terrible; it may be possible to improve the artifacting a bit but ultimately the rendering setup exists to cope with the resolution of the displays. The state of the art in cost-effective HMDs will need to advance a bit for this to really get “fixed”, as TFA notes.

It is telling that it took a very contrived test (a white grid of fine lines on black) for this to be obvious. Most things displayed by most users won’t run into this problem.

I agree that this thing is not yet monitor-replacement-level yet. I mostly just want it for watching movies in bed or on planes.

$5 to $7 Trillion? Developing cutting edge chip fabrication technologies is insanely expensive but that number still strikes me as far too high. Unfortunately, the article doesn't go into any detail on the allocation of funds for a capital raise that unprecedentedly massive. I don't doubt that Altman may have cited that range, my skepticism is more centered on the practical possibility of productively putting that much money to work in a relevant startup time frame (~five years). Maybe there's missing relevant detail, like perhaps he was referencing a cumulative total spend over a decade or longer.

Just for comparison TSMC's market cap is ~$500B, ASML (who makes the cutting edge fab machines) is ~$350B. NVidia itself is ~$1.7T but that also includes non-AI things. Even if you include buying smaller players in addition to those, you could theoretically outright own the entire relevant market for less than $3T. And that's at full de-risked, retail public market price in a very frothy time period. The new venture cost should be less, otherwise investors would be wiser to just buy the existing players with all their IP, proven know-how and market momentum.
> The person created probably close to trillions of value to humanity (his LEDs spawned multiple new industries), yet he was compensated less than what I make with web development.

While decrying unfairness towards a single researcher, you seem to ignore the contribution of who knows how many people comprising "multiple new industries". I mean, the people working in those industries also contributed to those trillions, no?

It definitely seems unfair to Nakamura. Just pointing out it's really hard to be fair to everyone, as your comment inadvertently proves. At least he got a Nobel prize, which means both recognition and money.

> In what world when server is down people wait for the next standup to announce it?

I'm not sure why this is so strange to you. There are many possible scenarios where a server can be down, with varying levels of severity/impact to our team.

It happens all the time. I have 4 things to do. One of them involves a server (that we don't own). It goes down. I file a ticket and work on the other 3 things. It doesn't need to be resolved immediately. But if it isn't resolved in 2+ days, it may affect our timelines. People should know. If it got resolved in a few hours, I've wasted people's time by emailing them.

If it's critical and we need it resolved ASAP, sure - email/IM others in your team immediately to let them know.

> Why not just create a shared channel (slack, teams, mattermost, irc, whatever the company standardized on) and use it to communicate asynchronously and resolve problems like that immediately?

This was answered in my comment: People often ignore it. I can't count how often I've been in non-SUM teams where a developer is asked "Why didn't you tell us?" only to have him whip out one (or several) emails/IMs where he did tell it. Calling it out (repeatedly) in a SUM gives other developers less deniability, and the SM will highlight it: "This person has pointed out 3 days in a row. What's preventing it from being fixed?"

But the question for you: Are you always going to leave it to the individual developer to decide what is important to tell others? He may view it as unimportant whereas others believe it is. Making them explicitly say it as a blocker in a daily meeting ensures the disconnect doesn't last long.
I thought of that, I am not rural (town is about 300,000 people)... Perhaps that is rural in some areas I guess.

The HVAC contractors here are pretty small, maybe they do not want to take the risk.

As someone else said, if I had more time, I would have purchased a few DIY split systems... I might do that for AC only, as I did not replace the AC at that time.

I have a suite of LG Minisplits installed in my apartment. While there isn't a distinctly open API, there's an integration that you can add to Home Assistant for access to the platform.

From there, I've got a few automations including:

- Automatically turning off "conflicting" units (Heat vs Cool)
- Schedules (set bedroom to cool at night) and "Away" modes
- Temperature overrides using custom built temperature sensors (BME280 to the rescue)
- Access and control via voice (via Google Assistants)

Unfortunately, the integration is reliant on the cloud, but you can connect a "traditional" relay based thermostat to them as well (with the loss of variable load control for the outside unit).

> Is this some old building?

Not that old. 2010, maybe?

It's a building with 4 stories. We're on the second (Portuguese would call it the first floor; like hackers, they count the ground floor as zero).

If you walk out our door, you see an elevator and a stairwell with an insulated steel door to the stairs. That's it; that's the only point of egress.

Though in a pinch, I could jump from the balcony and probably just break an ankle or something.
Single family homes are easy to build. I could build one myself - just myself in about a year (worked on a framing crew and have done every part of building a house). With access to experienced subcontractors (plumbers, concrete...) a house can be built by "one man" in just over 100 days, and banks will even give construction loans to someone wanting to attempt this - most inexperienced people can create enough of a plan to convince a banker that in less than one year they will have a house more valuable than the costs and so they will then get a regular mortgage on it.

However apartments because of size quickly get to the point where you cannot build them without already having experience. Banks know that the details are just enough more complex than a small house that they won't risk a loan on someone without experience. Which opens the question: how do you get experience without experience?
Common advice to beginners:

"Improve the position of your worst placed piece."

For better players, determine which is most effective:

1 Improve the position of your worst placed piece.

2 Exchange or minimize the potential of your opponent's best-placed piece (e.g. trade off their bishop on a long diagonal)

3 Maximize the potential of your best-placed piece (sometimes by a sacrifice)

4 Prevent your opponent from developing some pieces

This is over-simplified, of course, but the balance of the position must be taken into account.

"Many women allege that domestic violence is almost always ignored."

And you think, that is a good thing?

There used to be laws up until recently, saying there is no such thing as rape in a marriage. And that husbands need to tame their wifes. Some policemen amd judges still think like that.

Not my take.

And everthing else you argue, was besides every point I made.

I said explicitely, that police needs to investigate upon violence especially in political context, to determine if it is a real threat. Not to process every bloddy nose and not with guilt by association - unless the other protestors do celebrate the violence. Then there is at least suspicion by association and also possible guilt. Do you debate that?
