AFAIK there are actually no 1500w HPWHs currently, the normal hybrid 220v models have a small 500 watt compressor thats very efficient and keeps the airflow requirements low which helps with installation placement and ducting if needed, then still have the electric elements if needed to boost.

The 120v model HPWH's I have seen do not have electric resistive elements and instead have around a 1000W compressor, so they recover faster purely on heat pump and can run off a standard 15 amp circuit while staying well under the NEC 80% rule which would be 12 amps, they are closer to 10 amps.

They do require more airflow and are generally noisier due to larger fans and compressor.

Then you have dedicated split system HPWH's like SANCO that use an outdoor unit like a minisplit and pull around 1800 watts putting well over 6kw into the water, these are probably the future or whole house heat pump systems that heat both water and air(and cool) as combined unit.

That sounds very familiar to me... I know of a guy like that, who will rapidly jump on and propose and implement half-baked "tactical" solutions to any production incident. As you say, he is valued by management, because he is very responsive, at all hours, and always has some kind of snake oil "fix" to offer for any problem, and generally maintains a bit of a "mad scientist" vibe.

The issue is that, most of his "fixes" are just rearranging deck chairs, increasing timeouts, decreasing timeouts, adding memory, upgrading random libraries, etc., and he's constantly operating in "emergency mode", trampling on other people's work and priorities to get his "urgent" stuff out the door. He also just sort of throws things at the wall - "what if we change / disable X to fix this, would that break any client use cases?"... well, I dunno buddy, you are the one proposing the change, you have access to the logs, you are the genius, why is it _my_ job to evaluate your stream of half-baked ideas to separate the wheat from the chaff?

Ultimately, we co-exist, and I'd even say there are things to learn from him, i.e. being responsive is important and hugely valued. Over time, I've learnt not to get sucked into his urgent, half-baked proposals to save the world, I just say look, if you think that's a good idea, go for it, do it, but... you don't get to force it down everyone's throat and pretend there is consensus, I have my own, different priorities that I am not going to drop for you.

I have the same experience. I have felt it specially when moving to a new iPhone with 90 or 120Hz screen refresh frequency. Everything is so smooth that becomes pleasurable already by itself.

But not only that, also my work iPhone got recently upgraded from an old SE with small screen and laggy performance to the new 16e, and I found myself more eager to check work emails, ms teams than ever before.

I don’t think that’s a good development, but at the end it’s my responsibility and my own decision on how I use those devices. That also means I will probably downgrade to a worse iPhone instead of getting the best available.

> Framework machine with Fedora

Unfortunately Framework only ships to a limited amount of countries, and they also prohibit commercial resale and go out of their way to block parcel forwarders. So as a result, it's not available for ~90% of the world's population, so I wouldn't recommend it as a general recommendation for a global audience.

> I use Project Bluefin which I’ve found to be fantastic

Why Bluefin and not Aurora (KDE)?

> You can get Ubuntu pre-installed (I heard that’s the better choice over Fedora for Lenovo) and select from a few curated options

Not sure where you heard this from, but Ubuntu is possibly one of the worst Linux distros you could've recommended. It might work fine initially, but it will eventually break during regular usage/updates (generally due to Snap, or due to other Canonical shenanigans). Even if you disable Snap, there's a good chance it may break during a dist-upgrade. See: https://ounapuu.ee/posts/2025/02/05/done-with-ubuntu/ and the related HN discussion: https://news.ycombinator.com/item?id=42949222

There are times where it is reasonable, especially for bug fixes where there is a test to explicitly check that the bug is fixed. In that case, I might check out the code, revert the fix, and ensure that the test fails. There have been a few times I did that and the test still succeeded, so I can confirm that the test is not testing the right thing (in a very mature project, complexity or test settings can obscure what your test is actually doing, especially if it is an E2E test).

for me it got dramatically worse. it cant read whole files of concatenated code anymore. seems like its attention is much smaller. doing lots of piecemeal behind-the-scenes cmd line stuff now instead of just seeming to "understand" everything in one go. somewhat catastrophic for me. so bad that i was surprised to discover that chatgpt 5 is still worse

As far as my doctor's diet guidelines go, that'd be 'effectively 17g of "sugar"'.

I've been told to use an offhand rule of fiber vs sugar as a ratio. For every 1 gram of fiber 'up to' 50 of carbs ~ calories, with lower better.

Fiber also has other benefits https://www.cdc.gov/diabetes/healthy-eating/fiber-helps-diab...

This is pretty neat. I remember making floppy-based "distributions" back in '98 to do utility tasks (imaging Windows PCs over UDP broadcast being one I spent a long time on). So many memories of "make bzimage", hanging init scripts, reboots. So many reboots.

Charmingly, the "modern" process doesn't seem wholly dissimilar. I would echo the comments of one of the sibling comments here: Targeting this to RPi would be fun and educational. Maybe I'll give it a try.

Agree. I wouldn't say it's broken; the somewhat-overlapping Venn Diagram metaphor is apt. But like many other domains of power, there's a persistent belief that those who are recognized (promoted) are indeed the best candidates and that false negatives eventually correct themselves.

Believing otherwise is psychologically dangerous: if the system is somewhat arbitrary, then that opens up the possibility that their promotion was also somewhat arbitrary and not under their control.

This got both of my parents. What's interesting is that neither of them really used a computer or smartphone much, but both got addicted to iPads in their late 60s.

What they do in their free time is their business, but it often even messes with human interaction. I've been midsentence with them in person when they'd just pull out their iPad for a quick scroll, completely oblivious that I was even there or talking to them. What's weird is that it almost reminds me of a person taking a quick vape or smoke... I'm not even sure they realize why they're doing it.

I remember watching one of the first React demonstrations/talks, and the biggest selling point was literally "You have a web page with various elements, and some of them needs to keep in sync, at Facebook we have chat messages and notifications, and they need to be in sync regardless of where you are, even on the same page, how do you solve that?" and then outlined how having one place for the state to live solves that issue without resorting to two-way data-bindings, instead data only flows in one direction.

Not sure if React isn't being presented as such anymore, but that's still the problem I see React solving, not more, not less.

Imagine if compilers were only available via the SaaS model. Developers and the tech community in general would never accept this, and compilers were open sourced well before the internet had developed to the point where it would even be possible. Nobody would trust a system that sent their proprietary code off to a data center to be compiled to binaries for their platform on a monthly subscription model - the idea is ludicrous.

Currently the only SaaS product that still makes sense are LLMs, but this is temporary - anyone with sense realizes that the ideal situation is to run an open-source LLM model locally and privately, but this still requires a significant investment in high-end hardware and IT technical people.

That's the basic calculation: is it overall more efficient and less expensive to hire a skilled IT team to manage your in-house solutions, mostly open-source, including security patches, than it is to rely on external providers who charge high monthly fees and use all manner of sneaky tactics to keep you locked into their products? The latter is going to win in the long run.

If you already don't believe me, and want to think the worst, I won't be able to change your mind.

In another comment I've explained why I think this "OP is the real problem" narrative probably isn't the case, just based on other data points I've had.

> You have a engineer in your team who thinks you are a looser and incompetent. This is why he second guesses you at every point, because he does not believe that you can make adequate decisions

I do think this is broadly correct, though.

> they have very little respect for you as a leader, they love working with you because it allows them to do what they want

This is incorrect. They actively seek guidance from me regularly. As I mention in another post, three engineers joined the team specifically to work with me. I don't have doubts about this.

> The opinion of your boss towards the "problem engineer" seems quite positive

This is wrong too. He's called him an asshole.

> Nobody respect your leadership. Your staff doesn't and your manager doesn't.

This is also wrong. I was promoted recently. My reviews are strong in a tough, calibrated org. My team is widely trusted, a complete 180 from the state before I joined when it was falling apart.

Again, if you're already dead-set on reading the worst, you'll be able to do so. But I came here for actionable advice. You gave judgment, but not advice. What's the point?
Show HN: Xcuts – A package manager, shell, and more, made in iOS shortcuts
by libHacker | 2025-10-25 14:39:45+00:00
Xcuts is a programming tool designed to help people create shortcuts (or javascript programs), and to be able to package and run them. It took me a while to iron out all the issues.

I added tons of features to Xcuts, including:

- a way to run js programs, which can depend on js libraries, in ShortTerm - lots of commands, such as: head/tail, touch, mkdir, file, date, echo, wget, cd, qlook, exit, mail, grep, rm, ls, cp, sort, cat, mv, and $SB (.sbundle archive editor and text editor). - automatic recursive dependency resolving and autoremoving - a core unix-like filesystem stored in iCloud drive/Shortcuts/ROOTFS or, in ShortTerm, simply /ROOTFS. - a program that lets you display html and create callbacks to the shortcuts app that can make changes to the html displayed (UICuts).

This is all written in shortcuts, so that means you don't have to install any apps. In additon, it's offline and you don't have to connect to anything.

I recorded some demo videos: [https://www.icloud.com/sharedalbum/#B2d5oqs3q2kl8t2]. One of the videos showcases something I ported to Xcuts, called csvf (https://github.com/matthew-james-brewer/csvf). It's written in javascript + shell script.

I've been working on this for a while. What do you think of it?

> My computer in 2010 was achieving basically the same tasks it achieves now - I can browser the web, buy goods online, watch videos, chat with people, play video games, and so on. My computer today is 10-20x more powerful than the 2010 one, yet somehow everything is slower, uglier, and less reliable.

The problem is that everything after `-` is a service. Someone needs to keep those running.

By way of analogy: You don’t pay Walmart a one-time $30 fee and expect fully stocked shelves forever. You pay a small portion of every purchase to keep the supermarket service running.

> You're lucky. In my experience no-call lists don't work.

I don't think so, I've had friends and acquaintances that had the same issue as you, multiple spam calls per day. I helped them add themselves to their national list, and after a month or two the constant spamming stops.

I think you might just be unlucky living in country that doesn't have such list that works OK. I've lived in multiple different countries so far in my life, and it's been the same thing in all of them, adding myself to the list eventually makes the spam stop.

In feedback and promo docs my leadership and soft skills were called out as exemplary and distinctively strong.

If anything it's the opposite. I don't think my technical skills are as strong as some peers at my level. A big part of the difficulty is that the other engineer is more experience in certain technologies than I am. I'm self-aware enough to recognize those cases, and don't try to override him.

I made some open source software myself and my desire is to see my code used as widely as possible.

So the ONLY reasonable choice for me is to release my code with a non-viral license. A copyleft license is TOTALLY UNREASONABLE for me because it limits the reach of my software.

(My license of choice is MPL-2.0)

I think it's also important that HN doesn't have infinite scrolling. It's old-school: 30 items per page, click at the bottom to go to the next page.

I made a rule for myself that I would never go past page 2 of HN. So, each morning, I see 60 items, and if none of them interest me, then I just move on with my day. I think that's why I never became addicted.

For products like Photoshop and AutoCAD, it would have been great to have the option to use it for a few months and stop. This way, I can subscribe when work is available and I can offset cost by earnings. Of course, I am speaking as a freelancer.

However, what I understand is that this level of on and off of subscription is very difficult.

I've come to the opinion that for the vast majority of apps I've built, it could all be built using HTML + CSS (all built server side). I can sprinkle in little bits of interactivity using something like HTMX. And I'll have a website that is very easy to optimise, has phenomenal backwards compatibility, and gets rid of a whole class of issues associated with SPAs.

I often regret in my career not pushing back more on "requirements" that ended up requiring a more complicated app, whereas the customer would have been happier with a simpler solution.
by stavros | 2025-10-25 14:42:51+00:00
There's only one reason for this: You aren't the customer, so your incentives aren't aligned with the vendor's. Your data is being sold to other companies, so you getting value out of the software is only necessary insofar as it keeps you there. That's not where the vendor makes their money.

Classic enshittification. Unfortunately, I have no idea how to evade it.

What would you recommend/what do people do for power and access for in-wall sensors? Pulling power at least once per room (assuming you can share at least 1 node with another room) and being able to access it if you need to reflash feel like hard problems.

OR, am I completely missing the point that it's "through walls", not necessarily in-wall (though that would work). A wall-wart-sized device containing the ESP32 board could be plugging in to each room and share the node (on the opposite wall) of the next room?

Very cool project and love the HA integration as well. I'm using PiR and mmWave (Z-Wave and Zigbee) currently but obviously you either have to run power for those or deal with replacing batteries, this seems much more maintainable and unobtrusive.

When a person leaves an organisation, it’s difficult to find all the various team accounts they have been added to in order to remove them. So you end up in a situation where people no longer in the organisation frequently still have access to anything non-SSO.

That’s a very obvious, legitimate security issue, why are you accusing people of being insincere about it?

The problem with Postman isn't that we couldn't pay the developer a living, it's that it had to grow and grow and grow until it could extract the maximal amount of money from whatever corporate user it could get, in the process losing what made it good in the first place (simplicity).

It's not an accident that my company migrated to three clients in the space as they all met Postman's fate, and we're probably going to migrate to a fourth one soon. I'm surprised Postman is still around, but I'd be even more surprised if it's doing well.

> You're the lead, so just assume that you have cart blanche to just book the meeting

You're right. I should just push this. I'm attempting to be collaborative but I'm ending up just being conflict-averse to the detriment of everyone. I'll do this this upcoming week.

> This is probably good feedback.

I'd like for it not to bother me so much. It just accumulates and has festered. I should've been more forceful and insistent sooner. It's been on the verge of being worthwhile to force the issue for a long time; it's an ambiguous case since it's mostly passive-aggressiveness, not plain meanness.

> Call him out on it. In public. Out loud.

I really can't see this turning out well for me. It's easy for me to smirk and laugh, and for me to end up looking like the asshole. I'd be playing his game and losing.

> And if he follows up "we can have a chat about this after the meeting" or "lets take this offline"

This is more my style.

Thanks a ton for this -- very helpful.

Most of the current elderly also grew up in an era where they believed cities and urban areas were bad, so they moved out to the suburbs where everything is farther away and requires driving. It requires a lot more effort to do anything and they have effectively isolated themselves.

My grandparents who lived in a city could walk down the street, get groceries, and easily meet friends for a snack or chat. Even when they were alone, they were part of a community. My parents' generation all live far away from each other, struggle to get out of the house, and are scared of strangers.

25 and 26 has been my experience with this as well (not at Amazon; at much smaller organizations) Those paradoxes happen there.

Just my opinion: one of the key mindset shift that happens before someone steps into staff and principal engineering is understanding that the technical choices you make are tradeoffs. You give up conceits (or one should) that a technical opinion is separated from context, while also getting to deeper technical principles that appear across architectural levels or disciplines (such as queues). You also see how technical systems are inseparable from the people using it, and being a part of it.

When you start seeing that, you start seeing that everywhere. You start to act in a way that is informed from that understanding. You need to be on the critical path in order to do what matters, but you also need to connect those dots that are overlooked.

But that is also one flavor of principal engineering. I tended to do the horizontal influence than deep technical and domain expertise. At early stage startups, people have to wear multiple hats, often exceeding the scope of what they were initially hired for.

My issue isn't specifically the subscription model, though it gets annoying and I prefer a one time fee, or the cost, I'm happy to pay, my issue is the lock-in accompanied with the SaaS subscription model. You stop paying you loose access to your work, esp. as most SaaS models aim for proprietary data formats and no, or deliberately really annoying and cumbersome, export abilities often only allowing exporting in their own proprietary formats "for backup", which are useless once you stop paying

Seems they were pretty spot on! https://trends.google.com/trends/explore?date=all&q=pytorch,...

But to be fair, it was kind of obvious around ~2023 without having to look at metrics/data, you just had to look at what the researchers publishing novel research used.

Adding heat to local water and returning it after one pass is the minimalist use of water. Usually there is little need for additives, like chlorine to kill bacteria. A lot depends on the water purity. Water with suspended food = chlorine to suppress assorted growths. This heat the water and can harm the ecology - depends on the volume/added heat. Often filtering is needed with algae etc and a small river plus large heat can damage the downstream ecology. Water is used because it is 'free' - a potentially false economy. Lakes are more tolerant, but not immune - depends on volume. Best use is water to cool in a closed system coupled with air forced radiators - these need additives for growth suppression and corrosion inhibition. This method does not use evaporative cooling, so it is less capable, but a sealed non contaminating system can be made. Most nuclear power uses evaporative cooling towers that evaporate large water volumes and must be treated for algae/bacteria/legionnaires disease and they must add fresh water and create toxic waste water that must be treated. It is a grubby business. Best is a pure air based heat dump, which is the higher cost as long as enough local air is added so the local environment is minimally affected. I expect local rules will be enacted to mitigate these effects

China doesn't have the resources to win a war.

The Malacca straits are to easily blockaded. China needs food imports and energy imports no matter how much alternative energy they build.

No, you can't truck or train it in over land.

They are still facing a massive demographic bomb. They're becoming increasingly authoritarian, which will begin to restrict their production efficiency. They may have a financial bomb as well.

Don't make the mistake that you think that India and Russia are going to be close allies of China.

Russia has extensive territories that China considers theirs historically. Likewise, India and China dispute many territorial issues.
