You can do it even even faster by replacing your if statements (works because the ascii values end in the digit they represent):

    if (d & 1)
       printf("odd\n");
    else 
       printf("even\n")

The article doesn't suggest that Bhutan has a future in the leadership of Tibetan Buddhism, but that when/if Tibetan Buddhism gets more fractured because of disputes around lineage, then Bhutan can become globally important in the thought leadership of Buddhism more generally, or maybe more specifically Vajrayana Buddhism.


There are 4 main schools of Vajrayana Buddhism: Nyingma, Kagyu, Sakya and Gelug, and the Dalai Lama is head of just one of them - Gelug. They have independent teaching transmissions and succession lines. There's common misconception about Dalai Lama being a kind of a "pope" for Buddhism at all, or for the Diamond way (that means Vajrayana) Buddhism in particular, which is simply not true.

Having said that, it is of course unfortunate that the issue with two candidates, one of them "manufactured" by the PRC regime, is on the horizon and most likely will happen. Please note this already happened for the Kagyu lineage, where two Karmapa candidates emerged in 90s; interesting that after few decades the Chinese one admitted recently he's not the real one.


Do you have a link to the Karmapa admitting he's not the real deal? I tried to google it but got nothing.


There is this: https://youtu.be/AdI4DMRFkm4

Although here he admits "he is not properly trained as previous Karmapas" that's not exactly the statement i claimed

There was also another one with a stronger statement, somewhere during covid, I need to dig more



Yeah, is-land means ice-land in Scandinavian languages.


There's been some development in crowd control, no? AI and robots will make this even better.

I remember somebody championing css features, I think Adobe, to make it possible to have overflowing content spill over into another container, like it is (was?) possible to do in Publisher. I'd love something like that, and have wanted it several times. But it was abandoned...


Never knew that. I think that in combination with CSS grid auto fill, that may have solved a huge chunk of paged columns.


Interesting. Now have a friend help you do it blinded.


Why would their way of handling memory for conversations have much to do with how they will analyse your user profile for ads? They have access to all your history either way and can use that to figure out what products to recommend, or ads to display, no?


It's about weaving the ads into the LLM responses overly and more subtly.

There's the ads that come before the movie and then the ads that are part of the dialog, involved in the action, and so on. Apple features heavily in movies and TV series when people are using a computer, for example. There's payments for car models to be the one that's driven in chase scenes. There's even payments for characters to present the struggles that form core pain points that that specific products are category leaders to solve.


What I want is a silent refrigerator, will this bring that? pray


I've been thinking about what it would look like to convert my GE fridge into a minisplit (i.e., move the compressor, condensing coil & fan outside).

You can buy R600a on Amazon right now. One $60 can will charge the system ~5 times.


With home HVAC, fridges, water heaters, and dryers all using now able to use of dependent on heat pumps I wonder how long it be before we see modular appliances that connect to coolant lines where the temperature differential is supplied by a central high efficiency heat pump.

Cars already have heat scavenging that can move heat from where it's being created through losses to places where it's valuable, like the cabin or battery pre-heating. Especially in cold climates it feels like homes should be next.


There's some commercial options for this, but it's not common. Usually, these devices just have their own compressors, because they all pale in comparison to the heat pump(s) used for climate control. For example, I have a HP water heater, and its heat pump is about 1/3 of a ton, whereas most homes need 3+ tons for climate control. Fridges are a fraction of that.

For HP clothes dryers, there's no efficiency to steal from somewhere else, because they use both the hot and cold coils - similar to (the same, really) dehumidifiers.

The tradeoff would also be running high-pressure refrigerant lines everywhere. That would require EPA certification (in the US, anyway) to connect/disconnect an appliance, and it would probably be less reliable. These sealed-system units are generally pretty reliable, because the refrigerant is installed at the factory under ideal conditions, and there's no connections that are made later that may be done poorly.


That is an interesting thought, but I assume that the working ranges of the different appliances are different so there would be some complexities and inefficiencies getting them all connected to a common circulation loop. If there was a thermal equivalent of a transformer used for alternating current, that would be amazing.


As far as I know all the common commercially available heat pump appliances all use the same refrigerants, so it doesn't seem like it would be that challenging.

In cars that have unified heat management the refrigerant cycle is handled as a separate element, with a manifold controlling individual coolant loops to each component. I'm picturing something similar for the home, with a coolant moving heat to and from each appliance using standardized communication to the manifold. There would probably need to be heat buffer tanks, but air to water heat pump systems for radiant heat already need this anyway.


A few years ago I was planning to build a velomobile that I would live out of for a year while circumnavigating Australia, and potentially indefinitely. (My plans changed.) I was disappointed at how hard refrigeration information was to come by (maybe I should have sought a traditional paper book), but I was kinda looking forward to figuring out if I could use one compressor to cool a small fridge, cool and perhaps heat the cabin, heat water, and heat a slow cooker (target 80°C). The bits I could work out suggested you might want a different refrigerant for the cooling and heating applications, or different back pressures; but I was rather hampered in my reckoning by my lack of domain knowledge—I was definitely going to have to talk to professionals! If so, and combined with the limited power collection available (<1m² usable solar panels on the vehicle, could lay out more while parked), butane was probably going to make more sense for cooking.

I even ran some naive numbers on the amount of water that would condense in expected conditions, concluding it could be handy but I’d probably still need to source more water.


It's worth noting that the very earliest electric refrigerators had a separate condensing unit outside; see this interesting 1920s Frigidaire training video for an example of what that was like: https://www.youtube.com/watch?v=W-t7DqOAMME

There were also centralised systems for apartments where one condensing unit supplied many evaporators in the refrigerator in each suite.



That would've been easily invalidated by prior art from nearly a century ago; as I mentioned in a sibling comment, this was a common arrangement in the early days of domestic refrigeration.

Here's a video from someone who managed to salvage some of the components of such a system: https://www.youtube.com/watch?v=h1tXIYl20jA


Absorption refrigerators have been around for approximately a century, are silent, and a little more efficient than peltiers.


I used one for a couple years as my primary fridge. It was expensive, like $2k, didn't have very good temperature control and broke after 2 years and couldn't be repaired.


So... A little better than Peltier cooling in every other dimension too.


You can hear your refrigerator???


The latest wave of appliances is really fucking loud for some reason.

I think they're using different kinds of motor windings, bearings, insulation, etc. it's not related to the refrigerant or other system parameters. I've had older r600a fridges that were dead silent compared to anything sitting in a Best Buy showroom right now.


Likely high speed compressors --- the oldest hermetic systems used an induction motor running at 1800 RPM, then later they went to 3600 RPM, and now they're running on a VFD that possibly goes much faster. By making it pump faster, they can use a smaller compressor and reduce costs, at the expense of longevity and noise.


Ew.


They use lighter lubricant oils than were historically used, which allows more vibration. It’s also why compressors burn out far more quickly than they used to.



You can't? Refrigerators have always made a noticeable background noise as they cycle on and off.

The advantage of the newer variable speed scroll compressors in some high end fridges is that they can run continuously at a slower speed.


I'm not the same person, but I do not (and never have) noticed any noise when my fridge is running. Whether that means we have different fridges or different tolerances for noise, I'm not sure.


It's tolerance. I've bought several of the quietest fridges and they all bother me. Old fridges sound nicer but newer ones are actually quieter.


Is it the fridge noise in particular or all noises that you find you are sensitive to?


In practice the fridge is the only common thing. Most stuff in a house is quiet or, like fans or furnaces, make simple sounds that are easy to ignore.


More likely you have a noisier house/neighbourhood. I used to think my PC was silent until I moved to a quiet place and then I could suddenly hear it very clearly.


In an "open home" concept I guess it might make sense, but I've never lived in a place like that.

I guess all of the places I've lived the kitchen was always its own room, maybe adjacent to the dining room if anything.

No new appliances (>10y now I think about it, they came with the house.)


Yes, absolutely. In particular, I find this obnoxious when staying in hotel rooms that have a minifridge.


My wine fridge uses Peltier and is super quiet. It's the perfect application for this because wine doesn't need to be as cold as a normal fridge, and noise is a consideration.

It's not completely silent though, there's a small PC-like fan but it's way less loud than a compressor.


You might be able to swap that fan out for a higher quality one like a noctua.


oh thanks for the tip! I'll look into it.


They already exist! Well, small ones.

A hotel I was staying at had a small bar fridge that used a Peltier. I only know because it stopped working so I checked it and realized it was only a Peltier plus a heat exchanged (a cyclopropane loop).

I presume a full size fridge is outside of reach at this point.


Move it outside a cabinet, let it free stand. I found out that my nice kitchen niche for the refrigerator acted like a nice resonance chamber for the frequencies the compressor generated.

I can barely hear it now.


If the cabinet is poorly designed (or ventilation is otherwise obstructed), it will also retain heat, making the fridge have to work harder.


Simplest solution would be to have a compressor that is only active e.g. during the day (when the user is not at home).


But the user doesn't open the door when they aren't at home.


There will be greater fluctuations of temperature but that doesn't need to be a problem.


Peltier modules have no moving parts, so they're inherently silent


Why?


Not OP but it's a massive nuisance if you live in a studio. People don't realize how noisy a fridge is until there's one in the room that they sleep in.


New appliances are far better than old ones here. Especially old ones that (I assume) haven't been maintained and so are working far harder than they used to. I've lived in places with old ones that were fine and old ones that were awful, both. I've had much more consistently good results in places with newer ones.


Skill issue on the manufacturer's part. I live in a studio and never hear the fridge. This is part of a fitted kitchen, though, but I doubt the panel hiding the fridge makes that big of a difference.


Just today I ordered a 32dB Liebherr; the previous one had 35dB and could be heard all around the studio (I measured the noise using a dedicated sound meter).


You're saying that 0.999...=1, and simultaneously you are saying that 3 × 0.333... = 1 and not 0.999...

What? How can it be that a=b and a≠c when b=c?


I'm saying that, in the hyperreals as well as the reals, I am 100% certain that 3 × 0.33... = 1. I am not as sure that 0.999 = 1 with the hyperreals, BUT, if it's true as the author claims that 0.99... ≠ 1 in the hyperreals, then it must follow that 3 × 0.33... ≠ 0.99... in the hyperreals.
