> Car infra takes next to nothing to plan and build. Trains, trams, metro, anything big at all really, takes decades, riddled with corruption, environment destruction, landscape change.

As opposed to building highways, parking lots, massive car sized neighbourhoods etc...?


I can't recall a strike ever preventing me from getting to work in my car?


My cat was missing for a few days about a month ago. It was really stressful. Currently, I’ve put an AirTag on her which works okay since she’s an outdoor cat but I still get paranoid when FindMy hasn’t updated in a while. I would really love to support this project!


Our cat once disappeared for a week and we still have no idea where he has been. We have already said good bye since we presumed it got caught by a fox or some other predator. Returned exactly 7 days later as nothing happened, in good shape, not particularly hungry, nor dirty. Go figure!


Some cats have multiple houses. Lots of people love cats, and if a cat starts frequenting their houses, they will start feeding them and kind of adopting them. Cat lives in the new house for a few days, then go back to original house, stay for a while, and go to the second house, and so on.


We considered this option, and since we live in a remote countryside, we actually asked the neighbors around in few km radius. None knew anything. Mystery still unsolved. Happened only once.


Probably stuck in a shed, barn or other outbuilding that is infrequently used by the owner. Cat goes in while door is open, sleeps, resident leaves and closes door, cat is now stuck. The cat however will hear an approaching human and rush the door when it's opened next.

It happens to cats all the time when you live near farms, you either get used to it or learn to keep your cat indoor.

(If you only ever 'adopt' stray cats, it's a reasonable coping strategy to consider their presence somewhat ephemeral)


Happens to mine all the time! I figured a while back that he was just staying on the outdoor bench of a neighbor, and he had access to the food of her cats.


First prototype is great anyway. Could be made smaller over subsequent iterations!


Wondering if flex PCBs would allow to redistribute some of the components around the collar instead of having them as one big chunk.


Better to wait for v2 or later of "the ultimate solution for pet tracking" (from the video).


> I don't particularly like vscode. It's heavy and slow and janky, particularly on older laptops. I don't like being sucked back into the Microsoft ecosystem after spending years getting away from it. But ultimately, I want to just get on with my job, and my job is not Lua Developer or Neovim Plugin Expert.

Personally I've started paying for intellij and using it with it's vim emulation. I know it doesn't solve the problem of being clunky on older laptops, but it is an amazing experience to use. I get the best of both worlds, I get really good vim emulation so I don't have to relearn editor shortcuts, I get the benefits of a modern full fledged IDE with many useful features that work out of the box with basically 0 configuration (debugger, git, tasks, etc.)


Same. I like it better than the vscode vim emulation, which is more “strict” and turns to the visual mode when selecting anything with the cursor. Which I personally think is the worse part of vim.


Intellij IDEs for my day job are awesome.

I do have a personal all-products license as well, but I hesitate to go “all in” and be dependent on them.

But it is ok to just use a lot of editors for different things. VS Code is ‘good enough’ a lot times. I like writing notes in emacs org-mode. NeoVim on the command line. Sometimes I use Helix, I think it hits a sweet spot between snappiness and minimal configuration.


No it’s not the same. One of them is an institution conceived through organisation of people, laws, traditions and customs, the existence and membership of which is a choice. The other categories are associations made by accident of birth. I don’t have a horse in the race but it is important to understand that those situations are not the same. When people say stuff like ACAB they are free to criticise the existence of the police as an institution as they please.

Just because someone says you are a Christian because you were baptized or whatever doesn't make it so. Religion is just as much a choice as an occupation.


> Just because someone says you are a Christian because you were baptized or whatever doesn't make it so. Religion is just as much a choice as an occupation.

Hard disagree here. I didn't choose to be born to parents of a fundamental baptist cult. I didn't choose to be subjected to physical abuse in the name of that religion, or to be sent to seminars ingraining deeply harmful ideas about self and the roles of men/women. I didn't choose to spend my entire adult life in therapy unwinding the bizarre ideas that had been hammered into me as a kid.

Yes, you can "choose" to leave your religion behind, but many cannot choose to avoid the indoctrination, abuse and twisted mental models that can come from the experience.

I left my faith behind around age 18. 20 years later I'm still actively working on getting rid of the rest of the baggage.


Okay but none of what you said refutes my statement. Being subjected to abuse is orthogonal to your religious identity.


> Religion is just as much a choice as an occupation.

That is a bit tricky.

Religion is definitely a choice if you're enough willing to make a choice, but most people just keep their parent's religion. People just believe what they were taught as children.

I'm atheist from atheist country so I don't necessarily get it, but it seems to be that way - see ratios of Muslim and Christians in Saudi Arabia versus Europe, for example.

Then there's more tricky cases where religion and ethnicity are heavily correlated or tied in even stronger way (e.g. Jews).


> but most people just keep their parent's religion.

Is that not a choice? Choosing atheism is arguably easier.


They cannot be serious saying that now law enforcement is better than a bad one. The latter you can at least try to change by joining and being a good guideline on how to be.

I know that sounds idealistic... but what are the alternatives? - A "new" police? What should make this better on second try? - No Police? I cannot imagine what would happen with people - A police that plays within the rules? Now i extend my argument on law people involved. They also have many bad actors and again the only chance i see is to be a good actor.

I'd be delighted to hear alternatives.


Only the one about blacks, no? Jew blanket statements that don't involve memes about noses attack the religion which is a membership to an organisation of people with traditions, laws and customs.


Correct me if I am wrong as I am not a physicist. I see a point that is important to consider, that you have potentially overlooked. First, you assume that dissolution of salt is a completely reversible thermodynamic process, which is fine. But considering it a reversible process, in order to reverse the process we need to do a certain amount of work which you have calculated. In order to do work we need an engine. The most efficient possible engine is a Carnot engine. It is known that a Carnot engine can never be 100% efficient (unless we can achieve infinite or zero temperature). Given that you calculated the amount of work needed to reverse the process, you still need to bound the efficiency by the efficiency of a Carnot engine. Alternatively you need to factor in the efficiency of a Carnot engine to get the minimum required energy input.


You are correct. Although technically, dissolution is not a reversible process. That's why you need to input energy to reverse it.

Carnot cycle, technically, doesn't apply to all energy sources directly.

For example, solar panels have their "hot side" at around 6000K, so Carnot efficiency would be close to 100%. Real solar panels have other limiting factors, and I believe the absolute achievable theoretical maximum is around 80%.

On the other side of the spectrum, wind turbines have very lousy Carnot efficiency because they're exploiting a temperature difference of just a few degrees. However, the "Carnot tax" is not paid by us directly, so we don't really care about it.


IIRC you can still buy iodine free salt, you just can’t advertise it as table salt. It has to be explicitly advertised as pickling salt or rock salt or the like. This is the case in many countries, not just India. It is arguably one of the most successful public health initiatives ever.


same was as in the US it is possible to get "ethanol", which is just alcohol that can't be legally consumed. One of my chemistry professors explained that their records keeping for "ethanol" was actually more much more strict than the actual hazardous substances they had in the lab.


That must have been exaggeration to ward off clever ideas unless it's in like Utah or something -- At my grad school in a fairly puritanical state, USP grade ethanol was just on the shelf in the supply room with no more security or record keeping than on bags of pipet tips. And yes, some people did learn that undiluted pure EtOH dehydrates mucous membranes most painfully


In Alabama you can only legally get alcohol from a state designated entity. This was at a state university, so they had a state license just like a store would. Along with that came all the regulations.


I think the subtle difference is that alcohol not for human consumption must be denatured, and can be synthesised.


No, that's the point. You can't use denatured alcohol in a lab. It has to be nearly pure ethanol, with some percentage of water.


My chemistry professors told us that if someone tried to drink the ethanol in the lab their throat would seal off and they would start to choke because it will suck the moisture out of your tissue due to it being nearly anhydrous.


My concern with some of these endavours is the opportunity cost to rescue services. Obviously, there is no question that if anyone is in danger in a remote location we should try our best to rescue them, but the corollary is that as a responsible citizen you should avoid putting yourself in situations where others have to go to great lengths to rescue you if it can be avoided.


Yep. Any rescue attempt here will endanger others at great cost.


Not an expert on submarine design, but if it's comparable to aircraft, each pressurization-depressurization cycle actually increases the stress on the vessel. Just because it worked once doesn't necessarily mean it will always work.

Yeah for which carbon fiber yube is a far more likely failure point given it's ulyrw low longitudinal compression strength not to mention risk of cyclic failure from delamination.


I think you’re right. The more I think about it the more I feel like Reddit to me is the comment section for thinks that either don’t have a comment section or have a bad comment section.
