Very excited to see this as an official project!

I've been toying around with multiplatform frameworks like RN and Flutter for a side project of mine but they never feel right. I'd rather use the native UI per platform and have a nice way to share business logic. KMP exists but I think for most developers wanting to build an app it's more common to build for iOS first, and then port to Android later if the app gets traction. With a little foresight of keeping shared code in a Swift Package, it seems like that's getting more and more possible which is great to see.

Since no current AI thinks but humans do I’m just going to dismiss anything an AI says out of hand because you are pushing the cost of parsing what it said onto me and off you and nah, ain’t accepting that.

Northern Europe tends to have a mild climate in the places where people live. The Northern US is significantly south, yet gets significantly colder winters. There are places in Europe that get worse than the Northern US - but they are places where few people live and so not normally what you are talking about when talking about Europe.

Though good heat pumps are hard to find in the northern US. Most installers only know of gas furnace + A/C, and don't even try to install anything else. As you get farther south in the US heat pumps become common, but there it rarely gets much below freezing and so they don't need backup heating systems at all.

The strength of your heat pump shouldn't be outside surface temperature, but underground aquifer temperature. Those two temperatures are related but not as directly as they seem. A good aquifer in certain cavernous regions of the US might stay about 55 degF year round, regardless of outside surface temperature. 55 degF is still below what a lot of people want their home to be year round so a heat pump still has to supplement heat somehow in winters (or radiators or what have you), but a "free" boost to 55 degF is still a better starting place than 20 or 40 degF outside temperature.

I don't think latitude is a factor in how efficient a heat pump you can find, I think the type geography under you feet is (probably where "interior" regions probably have more luck than coastal regions), combined with how well regulated or unregulated your area's aquifer generally is (things like nearby wells and industrial water dumping will effect aquifer levels and temperatures). (Maybe not enough heat pump proponents realize that you only have good, cheap heat pumps if you have a powerful EPA and other Water protection groups fighting the good fight in your region.)

Incidentally, the longer forced reset triggers stay legal, the more real machines will have their value growth slow and, almost certainly, eventually tumble. The only reason this hasn't happened yet is because most people aren't yet familiar with them and many of the people who are just kind of assume that once they really go mainstream the government will put a stop to it, meaning "real" machine guns maintain their special status and therefore their special price. If FRTs stay legal for a long time and survive public scrutiny, then confidence in their future will grow and they will then eat much of the market demand for machine guns.

Of course, some machine guns would always remain valuable for their desirability as antiques, as long as people remain interested in them. That presumption of future demand for your collection might be a relatively safe bet for cool old guns in America, but it's still a bet.

Sounds like a useful feature tbh. I wouldn't ever work for a company again that didn't have fully flexible working (no requirements to come into the office at all if you don't want). But I also wouldn't lie to my boss about it.

I guess you can always use the web version via a VPN or something. I doubt it can deal with that.

All Ds I know pre-Hamas invasion were pretty much the same and would never vote out of party lines, but they wouldn’t say it that way. Rs say it more explicitly. All Ds pretend to be “independent” but they will find a way to rationalize their D. Both bases are quite sticky. There are events like Hamas that suddenly make a change in specific subgroups.

My daily driver is a 2014 Thinkpad. The only mod compared to stock is that I maxed out the ram. It's been an absolutely amazing machine, especially given that it cost all of $200 second hand (W540). I find it really hard justifying buying hardware that doesn't allow me to do anything that I couldn't do before. Up to 2003 or so I was always chasing the latest and the greatest but now I find that I can do everything I need on this old beast.

I didn't mean for it to be misleading, I apologize. In the post I mentioned my concern over the economic viability of solving this problem for them, I intended that to be a clear signal of profit motive on my part.

That's true, I am more interested in gauging if this problem is worth solving in the first place than I am interested in finding a specific solution. I am nonetheless interested in helping my friends.

No, sorry, I can't share a link.

I recently got an “older” generation robot vacuum for this reason. I wish the dreame debug board was more accessible. The designer and creator purposely made it this way so people would learn how to solder. I could solder but I no longer have the time or patience to source my own PCB and parts. Thankfully, someone sells one premade on Tindie.

> Personifying the LLM as being capable of knowing truths seems like a risky pattern to me.

I can see why I got downvoted now. People must think I'm a Blake Lemoine at Google saying LLMs are sentient.

> If you find truth in what the LLM says, that comes from YOU, it's not because the LLM in some way can knows what is true

I thought that goes without saying. I assign the truthiness of LLM output according to my educational background and experience. What I'm saying is that sometimes it helps to take a good hard look in the mirror. I didn't think that would controversial when talking about LLMs, with people rushing to remind me that the mirror is not sentient. It feels like an insecurity on the part of many.

Possibly an occasional refresher would help. I think it's just a weird thing to have. A roving stop sign that appears and disappears conditionally is going to have some people not see it (people accidentally run stationary stop signs on occasion), especially if you don't encounter school buses often. It's been maybe a decade since I needed to stop for one myself, I honestly cannot remember the last time.

> The operating paradigm is wrong there.

Agreed. In the U.S., the two-party duopoly is a manifestation of the problem. Neither party really stands for any long-term principle anymore (if they ever did). Although both parties will still sometimes selectively campaign on some historical principle, once in power they'll strategically weaken legislation, craft loopholes, defund enforcement or stage manage their votes so nothing that really matters to their stakeholders changes meaningfully.

Anyone still invested in the Kabuki theater of party vs party, even on a 'lesser of evils' basis, is missing the real meta that's unfolding.

no that isn't what it means at all

a global /run/lock dir is an outdated mechanism not needed anymore

when the standard was written (20 years ago) it standardized a common way programs used to work around not having something like flock. This is also reflected in the specific details of FHS 3.0 which requires lock files to be named as `LCK..{device_name}` and must contain the process id in a specific encoding. Now the funny part. Flock was added to Linux in ~1996, so even when the standard was written it was already on the way of being outdated and it was just a matter of time until most programs start using flock.

This brings is to two ways how this being a issues makes IMHO little sense:

- a lot of use cases for /var/lock have been replaced with flock

- having a global writable dire used across users has a really bad history (including security vulnerabilities) so there have been ongoing affords to create alternatives for anything like that. E.g. /run/user/{uid}, ~/.local/{bin,share,state,etc.}, systemd PrivateTemp etc.

- so any program running as user not wanting to use flock should place their lock file in `/run/user/{uid}` like e.g. pipewire, wayland, docker and similar do (specifically $XDG_RUNTIME_DIR which happens to be `/un/user/{uid}`)

So the only programs affected by it are programs which:

- don't run as root

- don't use flock

- and don't really follow best practices introduced with the XDG standard either

- ignore that it was quite predictable that /var/lock will get limited or outright removed due to long standing efforts to remove global writable dirs everywhere

i.e. software stuck in the last century, or in this case more like 2 centuries ago in the 2000th

But that is a common theme with Debian Stable, you have to fight even to just remove something which we know since 20 years to be a bad design. If it weren't for Debians reputation I think the systemd devs might have been more surprised by this being an issue then the Debian maintainers about some niche tools using outdated mechanisms breaking.

you might lose that above-average enthusiasm and expertise

yes, but montessori training can be done in one year (if you do it fulltime, my wife did i over multiple years 2 or 3 months each summer)), and it is entirely child focused. very different from traditional teacher training.

if we assume that every teacher starts their training with some amount of enthusiasm then the difference in enthusiasm and even more so in expertise should be minimal.

Bad reasons to hate something are bad press for Tesla, and how many people are going to read past a headline that confirms their bias? This isn't limited to Tesla, mind you, and is a broader statement on clickbait, and the state of the Internet and media and society today. Of course, anybody on Tesla's side knows to take Electrek and the rest of the Inernet’s coverage with a grain of salt, but with rabid fanboys on both sides, it's hard to know how large a grain of salt, and when.

I never really finished the project, thus only the rough qualitative benchmarks you get at the bottom (measured mostly by profiling and size(1)); I saw that it wasn't enough of a win in the larger context where I needed it, thus it made sense to stop early instead of making exhaustive benchmarks.

The blog post was mainly for curious readers, I'm surprised it hit HN at all. :-)

If there’s a legit long term demand for energy the market will figure it out. I doubt that will be a long term issue. It’s just a short term one because of the gold rush. But innovation doesn’t have to happen overnight. The world doesn’t live or die on a subset of VC funds not 100xing within a certain timeframe

Or it’s possible China just builds the power capabilities faster because they actually build new things

Recently went with heat pump water heater and cloths dryer, very significant energy savings and they both work great using around 1/3 the energy.

Most of my energy is for HVAC cooling in the south and that is already a heat pump. The house is well insulated and also have solar so along with the water heater and dryer I am around net zero in mid summer and and now that temperature is more mild I am producing much more than using even with one EV as well.

It really nice to have an all electric house along with at least one car and a large solar backup system I am pretty self contained and don't really have to change anything if grid goes down.

I do not, in any way, disagree with holding Gaggle accountable for this.

But can we at least talk about also holding the school accountable for the absolutely insane response?

You talk about not selling to schools that have "zero tolerance" policies as if those are an immutable fact of nature that can never be changed, but they are a human thing that has very obvious negative effects. There is no reason we actually have to have "zero tolerance" policies that traumatize children who genuinely did nothing wrong.

"Zero tolerance" for bringing deadly weapons to school, I can understand. So long as what's being checked for is actual deadly weapons, and not just "anything vaguely gun-shaped", or "anything that one could in theory use as a deadly weapon" (I mean, that would include things like "pens" and "textbooks", so...).

"Zero tolerance" for particular kinds of language is much less acceptable. And I say this as someone who is fully in favor of eliminating things like hate speech or threats of violence—you don't do it by coming down like the wrath of God on children for a single instance of such speech, whether it was actually hate speech or not. They are in school; that's the perfect place to be teaching them a) why such speech is not OK, b) who it hurts, and c) how to express themselves without it, rather than just treating them like terrorists.

?

I’m not sure who would really care about this feature.

We can usually tell based on your background. And the people that have to be in office are tracked typically with badge swipes. And if you’re really that determined to work remote and your company doesn’t support it, wouldn’t it be better just to find a company that does rather than sneaking around?

I attended one for elementary and middleschool. Early on everything we did was in groups. Take the multiplication flash cards and quiz eachother. Mess with the abacus. Look at the geological periods chart, etc. All the stuff seemed pretty fun to me. Yes, we had outdoor recess everyday, alhough we had a good setup with a big playground and some woods on the property. A lot of montessori setups I see now look really spartan like almost a daycare center.

But in hindsight I could tell it depends heavily on the teachers as well as the students you are saddled with because of how much group stuff there is. There was clear divisions between the kids who would reliably do their work and the kids who procrastinated and played around flicking pencils at eachother all day. This was generally possible while the main classroom teacher was busy with some subset of students for a lesson or some other work.

Once we got access to desktop computers we replaced the pencil flicking all day with games. They'd be in the main classroom but we'd just turn the crt monitors to the side to hide it. This was long before IT surveillance tools, we had full internet access too. Gameboys a plenty.

There was a lot of fluid experimentation however. At one point we took all the shelving in the room and turned it in such a way to create sort of cubicles. I think the idea was to get the kids who probably had ADHD to lock in and do their work more vs being tempted to socialize and screw around all day with their friends. Eventually they banned us from turning the CRT monitors as well.

Would a more rigid school structure help other kids? Sure, probably, but I don't think what public school was doing would have helped those kids much. Honestly montessori is a lot like the adult working world now that I am in that and see the parallels. A lot less handholding and you needing to not give into procrastination and ask mentors for individual direction from time to time. Group work and discussion coupled with independent work. Project based education that is more like actual real life work projects vs the dry lecture/memorize/exam patterns. That being said it was more "traditional" and less montessori towards the end as they had to prepare you for a proper highschool setup, so more formally scheduled classes and a lot less free time in the main classroom.

HN flagging is just shadow moderation.

I asked dang if I was shadowbanned from flagging. He said yes, if I flag something then it doesn't count because I flagged the wrong things in the past.

The conclusion is that flagging isn't really up to user choice, but is up to dang who decides which things should be flagged and which shouldn't. It's a bit like how on Reddit, the only comments you can see are the ones that agree with the moderators of that subreddit.

I use units(1), which also helps me avoid dimensional errors (dividing when I should have multiplied, etc.):

You have: 7.913e10 J / 550K / (1J/g/K) You want: kg * 143872.73 / 6.9505876e-06

maxerickson says, "Still big number," and 144 tonnes would typically be an unwieldy quantity of material if you had to buy it. But Standard Thermal's intention is not to buy dirt, just pile up already-on-site dirt with a bulldozer or excavator. If we assume 1.3 tonnes/m³, that's 110m³, or, in medieval units, 144 cubic yards. https://www.eaglepowerandequipment.com/blog/2022/03/how-much... tells us:

> An excavator could be used to dig anywhere from 350 to 1,000 cubic yards per day, depending on a number of factors including bucket capacity, type of ground, operator skill and efficiency level, and more. (...)

> One of the biggest factors that impact how much an excavator can dig in one day is the unit’s bucket size, which typically ranges from 0.5 to 1.5 cubic yards of bucket capacity. Most common regular-size excavators have a 1 cubic yard bucket capacity, and mini excavators are closer to the 0.5 cubic yard capacity.

So, with this number, we're talking about a few hours of work for a "mini excavator". https://www.bigrentz.com/rental-locations/pennsylvania/pitts... tells us that a "4,000 lb. mini excavator" rents for US$197 per day. So the expense of moving the dirt is not really significant, compared to other household projects such as replacing the roof, insulating the walls, or repainting the exterior.

Standard Thermal mentions that they are in effect firing the clay in the ground, that they've had significant trouble with resistance-heater reliability, and that their objective is to power steam-turbine power stations with the stored heat. These three facts lead me to believe that they're targeting a temperature closer to 1000° than to 600°.

Standard policy is I think mostly the same, but in Europe there's been arguments that those policies don't follow the actual consumer protection laws, which is a whole thing that I don't think really resolved one way or another.

It varies with country but I believe a number of protection laws specify normal use/testing a product is allowed, so you can open boxes and test functionality (norwegian law does this for sure). Excepting videogames from this is arbitrary, the argument from consumer protection agencies goes.

I believe in practice a number of games did get refunded when threatened with formal complaints along these lines, but that's far from a guaranteed thing.

Anyway, GOG decided to go with the generous interpretation (and the one all kinds of electronic goods except games and CDs/DVDs have), which is nicer for everyone, really

Resistive heat strips are what all electric furnaces use. It's just a bunch of coils of nichrome heating wire. The efficiency of a resistive heater is basically 100%. One Watt of electricity in gives you one watt of heat out.

The mistake people make is assuming a heat pump can do everything by itself anywhere in any climate. If you have cold winters, you need a dedicated furnace to supplement the heat pump.

I say supplement because while an electric furnace is near 100% efficient at turning electricity into heat, a heat pump can be far more than 100% efficient. And that's the crucial detail: a heat pump can give you more heat per Watt than a resistive heater when outside temperatures are warm enough.

> they're barely more convenient as raw sockets (there's framing, but framing is easy)

I think it's significant more convenient if your stack touches multiple programming languages. Otherwise you'd have to implement framing yourself for all of them. Not hard, but I don't see the benefit either.

> they also add a bunch of performance and complexity overhead over raw sockets

What performance overhead is there over raw sockets once you're past the protocol upgrade? It seems negligible if you connection is even slightly long-lived.

> And temperature 0 makes outputs deterministic, not magically correct.

For reasons I don't claim to really understand, I don't think it even makes them deterministic. Floating point something something? I'm not sure temperature even has a static technical definition or implementation everywhere at this point. I've been ignoring temperature and using nucleus sampling anywhere that's exposed and it seems to work better.

Random but typical example.. pydantic-ai has a caveat that doesn't reference any particular model: "Note that even with temperature of 0.0, the results will not be fully deterministic". And of course this is just the very bottom layer of model-config and in a system of diverse agents using different frameworks and models, it's even worse.

Thankfully this “update” shouldn’t affect me too much. We already have well established guidelines and schedules for remote work.

That being said, I feel like complaining about Teams. Who else is frustrated by its unusually short idle timer? Setting my status to “Away” after only five minutes just makes me look bad. There are definitely managers who somehow think that an 8 hour workday actually means 8 hours of continuous activity. Why can’t this be changed or configured to some other span of time? I wouldn’t complain about 15 minutes.

I got around this by downloading a program called caffeine. There are some other workarounds like preparing to start a fake call, or by entering a PowerPoint presentation and then alt-tabbing away from it.
