You mean condenser instead of evaporator, the evaporator is inside the furnace and has no controls as it’s just a coil. The outdoor a/c unit contains the condenser and compressor and has the contactor (and controller if it’s an EC motor) for the compressor motor. The contactor control coil is 24v and the contact is closed when a call for cold is received from the thermostat.

Newer A/C units have EC motors with variable speed motor controllers and newer furnaces will have an EC motor blower fan and lots of factory control points wired up to a controller, mostly for the burner (and related gas/burner safeties).

Still, even in newer furnaces and a/c units, the thermostat is the main controller as like you said, the calls for heat/cool are the only input to the system.

Commercial HVAC controls for air handlers, boilers, and chillers have a lot more control points, an AHU can have 40 or more control inputs and outputs tied to it. Discharge and return air temp, multiple differential pressure sensors, static pressure, outdoor air temp, outdoor air pressure, duct avg temp, etc. These systems are much more complex than any home HVAC setup and usually have multiple controllers networked back to a master controller which orchestrates everything.

But what determines that the UI has changed for a specific URL? Your software independent of the planner LLM or do you require the visual LLM to make a determination of change?

You should also stop saying 100% open source when test plan generation and execution depend on non-open source AI components. It just doesn’t make sense.

Alternatively, hi tom, you're a human being with opinions and you're allowed to discuss whatever you like on this site just like anyone else.

i think dang is successful at moderation in part because he does have a reputation and track record of being fair and unbiased in his moderation, and i do agree showing bias in conversations can make people question moderation decisions more, but i'm not sure tom is showing bias by including information relevant to people he knows, and i think he can both discuss however he likes while also being transparent and genuine in unbiased moderation

tom has and does stay out of debates and in-depth conversations around HN related stuff. he's simply dropping some information in to dispel disinformation, which i think is reasonable

Well, what do you today if there is a power outage for a couple of days and all your home appliances are electricity dependent? Do you think you should have learnt how to collect firewood and cook outside? Or how did people survive even before fire and cooking was discovered?

Nope, you don't need worry that AI would remove your skills. Those skills are no longer necessary, just like how you wouldn't need cooking outside using firewood. Alternatives would be available. If that means degraded quality of the things, so it be. That would be the norm. That's the new standard. Welcome to the new world. Don't be nostalgic about the good old days.

yes, this and the hope that i'll find a better opportunity to reconnect, like a better reason to call, so that the risk of rejection is reduced.

i recently reconnected to a bunch of people that i haven't spoken to in 20 years. i figured i am not going to find a better opportunity, and if i don't reconnect soon i'll probably never do it.

As is the thermostat is a set of brains that can be swapped in and out as time goes on. I just swapped two thermostats in two homes a few weeks back and it took <20 minutes each with no prior knowledge, even though in both cases I had to swap the backplate.

What is the benefit you see of moving the swappable brains closer to the heating system? Doesn't that actually make the whole system more complex because now you have two separate devices where there is currently one?

> To extend your metaphor: AI is like a magic microphone that makes all of my singing sound like Tony Rice, my personal favorite singer. I’ve always wanted to sound like him - but I never will. I don’t have the range or the training. But AI allows my coding level to get to that corresponding level with writing software.

My experience with LLMs leads me to believe that it's more likely that the magic microphone in this case makes you sound still very, very bad, but being that you're not a good singer you can't tell the difference between very, very bad and Tony Rice's singing. You sang the song, though, i.e. the solution was reached.

I'd argue that there's another perspective, more complimentary to US politics. There's obviously a list of "experts" aligned with RT narrative which they use depending on the topic. No media like RT wants someone from this list to be too visible and appear too often, whether they are pay-rolled shadowy or not. So it looks like not so many "experts" are eager to be on alert on this list.

After the recent spate of announcements for coding LLMs, I dug up a problem from my early days in programming contests.

A simple, naive solution from these LLMs runs 1000-2000x slower than the winning solution depending on the algorithm the LLM uses.

Asking the LLM to "make it faster" can knock the runtime by 10x. Close but no cigar.

Further prodding for even faster solutions sometimes shows glimmers of bridging the mental gap - but inevitably, the LLM doesn't know what to do with the newfound knowledge and wallows in its local minimum. Typically ending with "this is the fastest code to solve the problem".

Oh, grasshopper. You fail.

It wouldn't be so bad if this problem solving session was consistently reproducible. But every time I create a new session and give the problem, often times the naive solution appears. Sometimes the LLM can't even produce a working naive solution - even though the comments in the proposed source code shows the LLM knows what the correct answer is - the actual source code can't produce that answer.

Once, I decided to give some hints to the LLM to see if I could get it to jump the chasm. The LLM decided to limit its search space to a certain range - which I knew was wrong, and resulted in incorrect results.

I prompted the LLM to try and expand the search range, which it cheerfully tried and deduced an expanded search range - which was still too limited. Further prodding resulted in the LLM reverting back to the original search range. No amount of prodding would get the LLM to expand its search range. In a fit of rage, I told the LLM to use an arbitrary large search range which would cover the necessary search space. The LLM refused!

Dang - I was chatting with HAL from 2001 - A Space Odyssey.

I have been unable to repro that particular chat situation.

I guess we should be happy that the LLM can even produce a working solution - probably 5-10 years ago, we'd be gobsmacked. Even call it magic... But it's not remotely consistent.

> "Deports" is wrong word for removing a citizen. "Expels" would be more appropriate.

While this is true, the use of what's technically the wrong word highlights that the wrong action is being applied.

The action is a deportation. The targets are people who must/shall not ever be deported. Therefore the headline immediately gets attention for concisely describing a violation.

It depends what you're doing. High volume parts, absolutely. It's one of the things that bugs me about the "3D printers printing printers" type projects. 3D printing is terrible for mass producing parts. If you're making 1000+ of something, injection mold it.

Low volume, probably customized parts like R&D robotics tends to need? 3D printing is great, especially if the design files are available so you can modify the parts as required before printing. And then if you break something you can print another one off overnight instead of stalling your project for weeks waiting for new parts to arrive.

> Why can't they work on the local network? That would take no resources from Google

I'm guessing since the generations being shut down are explicit, I'm assuming there are more generations that aren't being shut down, so the simple answer is that they want to sell more of those devices, basically force people to upgrade.

So indirectly, letting people still use the devices locally, would mean they'll sell less of the newer devices, which probably have better margins, slurp up more data and will eventually be shut down too.

> "lose support" Is such euphemistic phrasing. Firstly "lose" is passive. Google is ending support

Indeed, had they started to support a product they would never say “15th gen Nest thermostats found support”. You know, they were walking through the woods and stumbled on some Google support. Isn’t that a nice coincidence.

Honestly, I'm surprised authorities haven't come down hard on these 'marketplaces' for neglience given how often they seem to completely ignore both safety and IP laws.

I guarantee a smaller company would probably be sued into oblivion if they were as relaxed about what they stocked as Amazon is. Same with an app store that was as willing to stock knockoffs and fakes as the iOS App Store and Google Play.

The fact these companies seem to be able to just stock anything and everything without any sort of oversight or quality control, and can just basically say "buyer beware" boggles the mind, especially compared to traditional retail and offline equivalents.

> It's not publicly known exactly how rich the Catholic Church is, as its wealth is wrapped in assets like real estate and art, but estimates suggest it's worth at least $10 to $15 billion.

That's laughable. The diocese of Paderborn alone, which is the richest diocese in Germany, is estimated to have 7.5 billion Euros. Cologne and Munich are also very rich.

The replies are getting absurd but unfortunately very illustrative of the state of Europe in 2025.

The "good intentions" have indeed led to a situation in which criminals are protected beyond the level of protection and rights afforded to victims and law-abiding citizens.

People can get in trouble by publishing CCTV footage to identify criminals, to give one basic example. But that's to be expected if some people think that even convicted criminals'privacy should be protected...

> A decade replacement cycle for network-connected computing devices is not crazy.

Sure it is, and it’s why we desperately need consumer protection laws mandating lifetime security updates for IOT devices.

My grandparents had a 100 year old home - some of their light switches were well over 30 years old. Why should I be forced to replace a smart light switch before its useful life is over? Because some company wanted built in obsolescence so they could sell more product?

Edit: and to be clear, I’m potentially fine if the vendor takes the approach of open sourcing all firmware as a way to allow lifetime updates if they need to get out of the product for some reason and can’t maintain it themselves. “Reasonable accommodation”?

I have 2 young kids, run a widely used open source project and a startup, eat dinner with my kids 6/7 nights a week and do this. Here’s some ways how:

My best friend comes over once a weekend and we watch the TV that my wife doesn’t want to.

I participate in a sport (powerlifting) where I’ve made friends and there’s room to socialise while exercising.

I chose to move back to my home town and also go to college there.

I go to metal gigs with friends when the kids are asleep.

I’m happily married, my wife is training for a marathon and sees friends too.

We pay for a cleaner.

Don’t know that this is 6.5 hours in person with friends every week but I’d say it’s at least a couple of hours each.

It’s doable, it just might require not doing some stuff you already do and enjoy. There’s a bunch of stuff I did pre-kids that I don’t any more and would like to find time for again one day.

I know you're joking, but it's women that get the short end of the stick in media.

Men are (within reason) considered handsome in media even in old age. Wrinkles and gray hair can be seen as sexy (again, within reason), but only in men.

Women are discarded or relegated to sexless granny roles (except maybe for comedic purposes, where sexuality is the butt of a joke). Actresses are replaced by younger women because they are not sexy enough even when their male equivalents aren't (looking at you, Top Gun: Maverick).

I'm not saying there aren't exceptions in particular movies that deal with this topic; I'm talking about the general trend.

To be more clear, it's operatives of the Heritage Foundation who now work in the government putting this into place. Does anyone think Trump actually does much day to day? He often seems completely unaware of what's going on in his own government. I invite anyway to watch his evening press conferences where he's handed a bunch of Executive Orders, is told what he's signing (he has no clue), and signs it.

If this was the 90s or early 2000s I might agree more. But these days I really can't. I have network devices over a decade old, they still work great and are useful, and my computer itself that I still play modern games on is also over a decade old. Sure there is newer faster stuff, but I don't need or really have much of any use for that. A thermostat isn't gaining anything useful with faster networking or processing or any of that because what it already had was already way beyond any use case.

hm. Doesn't the existence of Vulkan subgroups and CUDA shuffle/ballot poke huge holes in their 'SIMT' model? From where I sit, that looks a lot like SIMD. The only difference seems to be that SIMT professes to hide (or use HW support for) divergence. Apart from that, reductions and shuffles are basically SIMD.

its a pecking order of successful predators. like young hackers, performers or sports stars, but for the over-40s crowd. Don't you see the stage character photos there? he plays that every day, very well.. with a reputation that backs it. This is similar to a local wealthy high school getting a retired world football star to coach the boys, except that the assumptions of goals, methods and scoring are obnoxious and/or forbidden to most regular adults. predictable. Rabbits and wolves..

I’ll add in a hot take. I think the entitlement of the more recent generations has a strong cause for this as well. I’m not one to say that millennials or whomever are more entitled than previous ones but when it comes to romantic connection - I definitely believe some are.

We see the rise of online dating apps being the number one way (by a large margin) for urban educated singles to meet their future partners. If you’re in a place like SF or NYC, you can completely forget about meeting your future spouse at some hobby, the gym, or even in a friend group. I think a lot of this has to do with entitlement - a strong belief that a person deserves a match that is unwaveringly perfect/better-than-themselves. This Disney-ification of romance is very strong among certain crowds.

In my view, this has a strong effect on social circles. People won’t introduce anyone anymore. You might have a party and people might end up together but the idea of specifically inviting people or introducing friends to each other for romantic purposes is, practically speaking for yuppie circles, gone. The main reason I’ve seen is that certain people have gotten increasingly hostile to anyone even suggesting a person to them that is less than perfect/godly. To the point where many people are afraid of suggesting anything and therefore will not risk their own reputation and friendship because they really feel they’ll lose their friend if they even suggest a potential romantic connection.

So, anyway, my belief is romance within social circles is quickly dying due to entitlement and this has a strong pusher for people to not put as much effort into them. Once that is established, it carries over into the rest of your life because you didn’t ever prioritize it. Therefore, even if you’re partnered, you have learned to live without.

It’s shocking how few relationships I’ve seen are from social circles. If anyone ever studies how people 25-35, educated, and living in major cities dates… being single will be more common than any non-app method.

There's an auto fuel tax in the US. Increasing that from $0.184/gallon for gasoline and $0.244/gallon for diesel to say $1.50/gallon and $2.00/gallon would ensure massive losses for that party in the next two or three election cycles.

Increasing the tax on aviation fuel to $2/gallon wouldn't produce massive shifts in the next several elections, therefore it's easier to implement.

Well, software design and architecture are the big ones. Programming a system in its most basic sense is pretty easy, while structuring it so it's understandable and easy to maintain is a whole 'nother story. If you need a great example of what happens when you don't have that... well, look at any 'vibe coded' product going viral on social media. The creators have no idea what their tools are doing and no plan for anything going forward, so are drowning under a pile of auto generated code they have zero understanding of.

Feels like software security knowledge will probably remain relevant for a while too. It's all well and good getting an LLM to code the system, but without any idea of what exploits are being used against that language/framework/software as a whole, you're almost certainly going to get hacked at some point or another.

But to be honest, I'd also programming in general will still matter in 10 years, especially for more niche domains. Yes, stuff like Claude can throw together apps and programs in JavaScript or PHP or Python, but they don't have training material for every language or domain. If you're not working as a web developer, then things probably aren't going to change as much as you think they will...

The purpose of this evil is to spread fear, provoke a response and get publicity, push and prod the system for weakness/loyalty, condition their supporters to accept these atrocities as normal and necessary, and to communicate the blueprint by example, as it gets repeatedly acted out in public. The message is this is how we're operating, so if anything looks weird to you, trust the plan because we're on the same team (wink wink). I wouldn't be surprised if we start seeing domestic terrorism and public lawlessness go unpunished if it's directed towards immigrants, journalists, judges, and other 'enemies'.

The wall was a waste of tax payer money and purely theatric since it hasn’t helped. Saying illegal immigration is a problem today basically acknowledges as much if it weren’t also backed up by statistics.

https://www.cato.org/blog/border-wall-didnt-work

No, illegal immigration is not the same as an invasion by another nation.

I don’t condone harboring criminals but if they are indeed criminals they should be tried in a court of law because that is the American way. On the other hand if these illegal immigrants are fleeing violence rather than creating it, have lived here for years and/or have kids born and raised in the US, then I can understand the grace afforded them by sanctuary cities as deporting them is not illegal but ethically questionable. Deporting someone who has never known anything but living in this country to another one they have no connection to because their parents brought or birthed them here illegally would be legal but would it be justice? I don’t think it would, I think it’s more complicated.

The true absurdity is thinking due process is optional in this country. How the party that purports an unwavering belief in the founding fathers, constitution, law, and American exceptionalism compromised so hard on a fundamental right is beyond the pale.

If it’s optional for these immigrants then it’s optional for every citizen if Trump deems it so; the precedent is set, just call someone the enemy and you’re good. Your only defense that this couldn’t happen to US citizens would be the courts and an adherence to societal and legal norms both of which Trump has shown clear indifference to.

Addendum:

Amazing, it already happened and got posted to HN.

https://www.aclu.org/press-releases/ice-deports-3-u-s-citize...

“New Orleans, LA - Today, in the early hours of the morning, the New Orleans Immigration and Customs Enforcement (ICE) Field Office deported at least two families, including two mothers and their minor children – three of whom are U.S. citizen children aged 2, 4, and 7. One of the mothers is currently pregnant. The families, who had lived in the United States for years and had deep ties to their communities, were deported from the U.S. under deeply troubling circumstances that raise serious due process concerns.

…

In the case of the other family, a U.S. citizen child suffering from a rare form of metastatic cancer was deported without medication or the ability to consult with their treating physicians–despite ICE being notified in advance of the child’s urgent medical needs.“

Truly, justice in action, protecting us from criminal pregnant women and children with cancer. Probably MS13 gang members. What a great and powerful country we’ve become, Jesus would be proud /s

Look I’m not against law enforcement, I’m sure we have common ground somewhere, but how can I take the illegal immigration rhetoric seriously, take a hardline stance, if this is part of reality?
