Small addendum, there’s 94 commercial reactors that are generating power for the grid

But there’s a few dozen more active nuclear reactors that exist for things like training and research.

https://en.m.wikipedia.org/wiki/List_of_nuclear_research_reactors#United_States

I believe when talking about naval ships, commissioning is when they enter active service, so construction probably began early 90s, maybe even late 80s, and probably a few years of designing, bidding, etc before that. And of course there were probably all of the usual idiot politicians, bean counters, stubborn assholes, sales people, etc. involved who pushed for older tech. Maybe because everything else they had worked on the old disks, maybe they were skeptical of the new tech not being robust or tested enough or wouldn’t catch on, maybe it was just cheaper, etc.

I’m willing to bet that they somehow locked themselves into using 8 inch disks in the early to mid 80s if not earlier, when the 5¼ discs were still new-ish and the 3½ were brand-new or not even available yet.

His formatting leaves a bit to be desired, but that basically boils down to

1. Knives with certain features like a double edge, a handguard, butterfly knives and certain other one-handed opening mechanisms (I assume switchblades, maybe assisted openers, possibly gravity and flick knives) are weapons and can be owned but generally not carried

Otherwise…

2. Knives (and I assume this applies to other bladed tools as well since he mentioned an axe)with a blade length of less than about 5.5 inches are ok to carry for no particular reason, as long as either the blade doesn’t lock or it needs two hands to open it (from how he wrote it sounds to me like one or the other of those features is ok, but not both)

3. You can carry a bigger knife if you have a good reason that you need one, like if you’re going campings/hunting, or clearing brush with a machete (and from how he phrased it sounds like you could also carry a one-handed locking knife with a good reason)

4. You get carded to prove you’re an adult if you want to buy a sword (I assume knives as well)

Which is pretty straightforward, and actually similar to a lot of laws in the states (looser than some states I believe, and stricter than others)

Not really relevant to the comment you replied to and only tangentially related to some other comments in this thread. We’re talking about knives and soda caps here.

A lot of us don’t think of our knives as weapons, they’re tools.

It’s rare that I don’t carry a knife, and using it in self defense is the furthest thing from my mind every day when I put it in my pocket. I use it for things like opening packages, cutting string, sharpening pencils, use various other tools on the knife like screwdrivers, pliers, awls, I have a lot of outdoor hobbies like camping, hiking, fishing, and knives are kind of indispensable for those pursuits.

If I’m ever in a situation where I absolutely need to defend myself, and I don’t really foresee that ever being necessary, I’m probably not even going to think of using my knife in self defense, I don’t think of it as a weapon anymore than I think of my wallet being a weapon, it’s just something that lives in my pocket that I frequently need to use.

And knives make a shitty weapon, if you’re close enough to stab someone, you’re close enough to get punched in the face, or for your assailant to wrestle it out of your hands and stab you with it. You’d be better swinging around pretty much any larger object within arms reach to create some space. They say about knife fights that the loser dies in the street, the winner dies in the ambulance.

The knives I tend to carry especially aren’t good weapons, most need 2 hands to open, aren’t really designed ergonomically as fighting knives, most are fairly small so I’d have to get really lucky to hit anything vital and would probably just piss them off more and not stop the attack quickly, some of them don’t even have a pointy blade so not good for stabbing (I actually make it a point to choose less threatening looking knives for my EDC needs) some of them don’t lock open so they’d just as like close on my fingers as cause any harm to my assailant, and some of them actually lock in the closed position so definitely not good for a weapon.

I’m not saying that everyone who carries a knife has the same mindset. Lots of people do carry them as weapons, those people are idiots. And not everyone puts the same thought into the knives they carry and just get something that looks cool whether or not it’s functional for their needs.

I also don’t carry anything for self defense regularly and don’t own a gun (not opposed to gun ownership in general, but my thoughts on that are part whole 'nother debate,) in general if I feel like I need to be prepared to defend myself if I go somewhere, I just don’t go there. There’s a bit of privilege to that, since I live in a safe area and can make that call, not everyone is lucky enough to live somewhere they can feel safe. The only exception is the pepper spray I keep with my dogs leash, since my wife or I often end up walking her alone at night, and that’s more of a precaution against loose dogs, coyotes, etc. than against people.

There’s a lot to say about Americans’ love of violence and weapons and the sort of mindset we have about self defense, and overall I tend to think that a lot of my country is absolutely insane when it comes to those matters. That said, I also think people who look at the little swiss army type knives, or Leatherman multitools I tend to carry and see a terrifying deadly weapon have their own issues to work out too.

AFAIK, these tethered caps are mostly an EU thing (and at the very least are not widely used in my area of the US) and a lot of European countries are less knife-friendly than the US.

I feel like it’s a pretty common experience for a lot of us maker types- we come up with a solution to a problem, maybe we tried searching for one and came up empty, or maybe we just thought it would be fun to make from the get-go, then sometime later we stumble upon someone selling pretty much the exact thing we made and think “huh, so thats what these things are called” maybe with a touch of disappointment that your idea wasn’t as original as you thought, or maybe just intrigued because you just added another term to your vocabulary and you have a better idea what to search for next time.

Yours looks good though, It’s probably unnecessary but I’d be tempted to add like a U-shaped cradle piece to the top to help keep it in place if your computer ever gets jostled for any reason, and maybe a jam nut at the bottom to make sure it stays where you set it. Again probably totally unnecessary, but I always figure that if it’s worth doing it’s worth overdoing.

What sort of printer and filament/resin are you using? I’d worry a bit about it warping or sagging over time from the heat inside a computer. I know some materials can handle the heat better or worse than others, but I haven’t dipped my toes into 3d printing myself yet, so I may be overestimating how much of an issue it is.

And can your printer make decent screw threads, or do you have to clean them up afterwards with a tap and die or something? I’m not really up on the current state of 3d printers, but one of the first 3d printed objects I remember ever handling was back in high school 15 or so years ago. One of my teachers went to a conference where they were showing off new gadgets for computer and shop classes, and he brought back a couple 3d printed crescent wrenches for us to fondle. I remember the screws being really crunchy and they almost but didn’t quite work, so in the back of my mind I’ve always thought of functional screw threads as something 3d printers can’t quite do, so it’s wild to me if we’ve gone from barely able to make even a coarse thread with huge tolerances work to being able to make pretty fine threads with pretty tight tolerances.

Of course back then, they hadn’t even really settled on calling it “3d printing,” I remember that teacher calling it a “rapid prototyping machine” when he was telling us about it, and described it as being “like a 3d printer”

I may be misinterpreting what you’re describing, but it kind of sounds like you’ve reinvented the machinist jack.

Not throwing shade, it makes sense and there’s a reason that machinists the world over use them to tackle the same sort of problem of how to support sagging parts- it’s simple and it works. And coming up with the same solution shows that you have a good understanding of the issue and how to tackle it.

Just pointing it out because I love the overlap between different fields and hobbies, and maybe if you didn’t already know that machinist jacks were a thing you’ll find inspiration for a version 2.0 if you ever feel the need to make one.

I’d also like to see your version when you get around to sharing it.

I think the scam calls are annoying, but it takes basically no effort to ignore them when I’m not in the mood to mess with them, so I don’t mind them so much.

I figure though if I can keep one tied up talking to me for a few minutes that’s one less chance for them to be scamming someone’s grandmother. It’s a tiny drop in the ocean, but it’s still potentially one less person getting scammed that day, and that’s worth something.

So I don’t have any specific insight to what’s available in the Netherlands

But I kind of feel like maybe you’re explaining what you’re looking for poorly

First some terminology

SIM and e-SIM are basically how your cellular service provider knows that your phone is connected to your account. The phone that has either that physical SIM card inserted, or that e-SIM data gets the calls, texts, data, etc. that are supposed to go to you. Take the SIM card out or change the e-SIM, and that phone no longer gets those calls, texts, and data. Put that same sim or e sim on another phone and it starts getting all those calls texts and data.

VoIP is Voice over Internet protocol, basically sending a phone call over the Internet instead of over phone lines. This might be from a computer, or from something that looks like a landline phone (or maybe even is a regular landline phone with some sort of adapter) or from a cell phone with a VoIP app installed. To use it from a cell phone you’d need to have either a WiFi connection, or a cellular data connection, and to have that cellular data connection you need to have either a sim or e-sim.

I don’t think there’s any VoIP provider that’s set up to just use your phone’s dialer and text app to directly handle calls and texts (though I could be wrong on that, I don’t try to keep up with all of the different types of phone services out there) everything would have to go through their app. If you want to do that, and you’re either ok having no cellular data and all of your calls, texts, and data use would have to go over WiFi, or if you keep paying for a cell plan (and the associated SIM/e-SIM) maybe either just a data plan with no talk/text, or a regular plan and you just don’t use the talk and text parts, then you just need to track down a VoIP provider, sign up for an account, and install their app on your phone.

If you want to transfer your actual phone number from your cell phone to a VoIP account, either to use on your cell phone through that VoIP app, from a computer, or from one of those landline VoIP devices, I don’t think that’s really a thing. If you just want calls to your cell to go to your VoIP phone number as well you’re looking for call forwarding.

You might also be getting tripped up with things like WiFi calling, VoLTE/VoNR (marked by some carriers with terms like “HD Voice”) which are things that are all going to be dependent on a regular cell carrier, not a specific VoIP company, and may depend a bit on their network infrastructure and what features your partic6 phone does or doesn’t support.

Yeah, didn’t mean to imply that you were, just wanted to expand on options for deaf people that are already out there, and point out some of the relative strengths and weaknesses they have compared to text-to-911

This absolutely can be a useful tool for deaf people or others with hearing/speech difficulties.

However, there are already several ways for deaf people to contact 911 without text-to-911

I work in 911 dispatch, probably the most common way I’ve gotten calls from deaf people is through a video really interpreter. The caller is basically on a video call with an interpreter and they relay what’s being said to us. There’s very little delay in communication like there can be when you’re typing back and forth, and usually it works pretty well. There are some situations where it has its issues, if the caller is somewhere dark it can be hard for the interpreter to see what they’re signing, if they don’t have a video-capable device they of course can’t use it at all, and a lot of our deaf callers come from a behavioral health group home place in our county, and some of those callers have a tendency to just kind of walk off-street in the middle of the call, though it’s still kind of useful because the interpreter can at least try to describe what they’re seeing and hearing in the background if the caller didn’t hang up.

Also all 911 centers (in the US at least, I assume it’s probably the same elsewhere in the world) are required to take TTY/TTD calls. The classic example of these is the caller has a device that kind of looks like a typewriter with a little screen and a speaker and microphone they place a phone handset on. They type out their message,the device turns it into a bunch of beeping noises that go out over the phone line like a regular voice call, and the person on the other end’s TTY device (in our case it’s built into our computer phone system) decodes the beeps back into text. Most, if not all cell phones these days also have TTY built into them in the accessibility settings somewhere. There’s some grammar peculiarities because it doesn’t really include punctuation, and some tty users will use ASL gloss, which is a written form of ASL (ASL isn’t totally 1:1 with English, and if you don’t know what you’re looking at ASL gloss reads kind of like that bit from The Office “why waste time say lot word when few word do trick.”) It also allows for hearing or voice carryover, where the caller is able to hear but not speak or vice-versa, so you only need to use TTY for half the conversation and can communicate verbally for the other half. The 2 biggest drawback is that we hear all of these TTY beeps in our headset, and they get pretty annoying really quick, small price to pay though, and generally only one party can be typing at a time, so you have to wait for them to finish before you can reply.

I will say that, at least in my area, TTY is vanishingly rare. In the 6 years I’ve been here, I’d be amazed if we’ve gotten 3 calls from an actual deaf person using TTY, although we did have one mental health patient who used it on his cell phone and used it to just ramble nonsense at us. He had no hearing or speech difficulties, sometimes we were able to get him to talk to us

In either case, if you call from a landline, we get your address just like a regular phone call, with tty from a cell we also get your cellular location like a regular call. Video relay calls from cell phones can get a little funny location wise because of how the call needs to be routed, often it works out that we get a home address they have on file and not their actual current location. With texts the location data often isn’t very good (although we’re implementing some new technologies at my center that improve on it a bit, though it’s still not as reliable as a voice call in some ways)

I posted another comment/rant in this thread with some of my gripes about how people use text to 911 if you haven’t already seen that, and I do want to reiterate that it is a really good option to have available, we can always use more tools in our toolbox, and it can definitely be useful in some circumstances, but it does tend to get misused in some frustrating ways for us.

I work in 911 dispatch, there is an audible groan whenever anyone here gets a text to 911

Don’t get me wrong, I’m glad that it’s a tool that’s available, there are certain cases where it can be really useful, domestic abuse situations where you’re unable to make a voice call because you’re abuser is in the room or car with you, an active shooter situation where you’re hiding and don’t want to give away your location, people with hearing or speech issues, etc.

That’s almost never what it gets used for.

Most of the time it’s someone calling in some non-emergency. I suspect in their minds it’s probably quicker and more convenient for us to get a text, but it really isn’t. We’re not multitasking and taking other calls at the same time we’re on the text, when we’re on the text, that is what we’re doing, same as if we were on a regular 911 call. And that first text usually is missing some crucial information about what is going on, and it takes a whole lot longer to go back and for asking questions and waiting for an answer by text than if you just made a phone call, if they even reply at all to answer my questions, very often they put their phone in their pocket and never look at it again for the rest of the night. We can’t even call them back because we don’t know if it’s safe for them to speak on the phone, we just have to sit there for 5 minutes waiting for a reply that isn’t coming before we can disconnect.

I’ve also definitely had at least one instance where the caller was definitely texting while driving, and not for anything remotely urgent enough that they couldn’t have found somewhere safe to pull over first.

Agency policies will vary on how texts to be handled, I can only really speak for where I work.

Most calls, even a lot of actual actual emergencies, if my caller is cooperative and knows where they are, and the situation isn’t actively evolving while I’m on the phone, I can handle in about 2 minutes or less, sometimes I can even get it down to less than a minute. I’m going to easily spend twice that on most text conversations, and often I’m going to be tied up on it significantly longer.

Technology also varies a bit from one place to another, but we also don’t get the same kind of location info with a text like we do on a regular phonecall (and even on a call our location data may not always be super accurate or useful) we did recently get some of our systems updated, and we get more information than we did before, but it’s still less reliable than on a phone call.

And we also can’t transfer a text like we can with a voice call, so if you’re texting regarding something going on at your grandma’s house in another state (we get calls like that all the time, where someone tells a friend or relative about something going on, but can’t or won’t call 911 themselves) we have to either A convince you to take a voice call so we can transfer you, or B make a call to them while still texting you, and play middle man relaying questions and answers between you and the other dispatcher, so you’re tying up dispatchers in 2 jurisdictions on your call (it used to be that we weren’t able to make an outgoing call while we were on a text, so we’d have to have 2 dispatchers at our center tied up on these texts, one to message back and forth with you, and another to relay the info to the correct agency by phone. We’re a pretty well-funded county, so I’m sure there’s a lot of dispatch centers still out there where that’s still the case)

I already occasionally get people trying to send us pictures and links with no explanation (pro-tip, we can’t see your pictures or open your links with our current tech, and even if we could opening links would probably be a no-no from a cyber security standpoint)

If at all possible, please just make a voice call, it will be quicker. If you genuinely cannot make a voice call, at least make sure your first text contains the correct location (address, municipality, nearest cross street, apartment number or name of the business if applicable should cover your bases pretty well) and a good description of what is going on. Then please keep your phone with you and try to answer any follow up texts we send you quickly and succinctly.

And again, don’t get me wrong, it really can be an amazing tool when it’s needed, but it’s a massive pain in the ass for us when people use it when it’s not necessary and usually makes just about every part of our job harder and slower, which means slower responses to your emergency.

It’s going to depend a bit on the agency, different places use different systems and have different policies available to them.

Where I work, we used to have Google maps integrated into our CAD (Computer Added Dispatch) so it would sync to the built in map in our CAD. I believe it was some sort of 3rd party plugin, not something the cad developers officially supported, so it was always kind of slow and buggy, and some update that happened a couple years ago totally broke it so we no longer have that.

We do use Google maps through a web browser pretty frequently. We have most of the businesses, parks, schools, cemeteries, etc. loaded into our CAD, but they’re not labeled on the map, and sometimes being able to ask “can you see the Starbucks from where you are” can be kind of useful, and the satellite view is really useful for our more rural areas where they may not be many obvious landmarks and it’s all fields and trees.

Some departments have some stricter internet usage policies and such and may not be able to use Google maps.

Street view has its uses, mostly for narrowing down the exact address. Most of the time it’s not super necessary, we can send police out to the nearest intersection if needed, and they can find “the big house with a red door” or whatever themselves, but if we can narrow down the exact address, sometimes we may have important caution note attached to the address, and of course it can sometimes shave a few minutes off of our response time if our responders don’t have to go hunting for the right house.

One of the times street view came in particular handy for me was one time I had a 3rd party calling about something for a friend. They weren’t sure of the exact address, but they knew the road and some nearby landmarks that had it narrowed down to about 2 or 3 blocks. The caller kept saying that there was a “big yellow walkman” on the front porch, and was too worked up to really elaborate on what she meant by that. I turned to street view and just kind of went down the block looking at porches until I found one that had one of those fluorescent yellow/green “children at play” signs people put in the street that are shaped like a kid walking and it clicked that that was what she meant.

It’s not just youth, it’s people across the entire population that have issues reading maps.

I work in 911 dispatch, obviously a big part of the job is all about location. We spend a lot of our shift looking at maps on our screen trying to figure out where people are so we can send them help.

In training for a couple days, they busted out paper maps of our county and had us locate different intersections, landmarks, etc. our class skewed a bit younger, mostly millennials at the time (this was about 6 years ago) but also some Gen x and boomers. I’d say only about 3 out of the 12 of us were really proficient at all at reading a map.theru wasn’t any particular age bias, really what it seemed to come down to is “who was in boy scouts”

And it’s not a new thing, a lot of people have had a hard time with maps probably since maps were invented. It takes certain kinds of spatial reasoning skills that some people just struggle with. My boomer mom could never read a map, a lot of my grade school years were the days before GPS and half of my class always struggled with it when it came up in history/geography/social studies, it’s been used as a joke in movies for decades. It’s probably gotten somewhat worse since people don’t use paper maps as much anymore, but there’s also a “use it or lose it” aspect, I noticed that my own map and compass skills have degraded a little recently while hiking a new trail with a paper map, there’s probably a few older people who used to be pretty proficient at reading a map but would have a hard time with it since they haven’t had to in over a decade.

The zest has a very concentrated flavor, but not really any acidity.

However, ook into “super juice” it had a moment in fancy cocktail circles somewhat recently as a way to get more citrus juice from less fruit and also a product that will last longer in the fridge without the taste degrading.

Basically you peel your citrus, mix the peels with some powdered citric and malic acid (the ratio of acids depends on which citrus, I think lemon juice gets straight citric, lime and orange get a mix) and let them sit for a while, the acid pulls some of the oils and such out of the peels making “oleo citrate”, then you blend the oleo citrate and peels with water and strain out the solids and you’re left with something that is nearly identical to actual juice (and you could, of course, mix in the actual juice from the fruits as well)

I feel like there is probably something there you could work with to punch up your juice a bit. Maybe if you’re able to separate out the oleo citrate you could use that as sort of a citrus extract. Or if you just want more acidity and don’t need the flavor enhanced you could just add a bit of acid to the juice.

Technology connections on YouTube did a video on mini fridges a while back. He focused on the peculiarities of one specific model, but one of the things he did to try addressing some of the issues with uneven cooling was add a fan, and he found that it didn’t really help and made things worse in other ways.

IIRC, the fridge was designed expecting that certain parts would be cooler than others and accounted for that in how the compressor cycled on and off, but with the added airflow those parts stayed warmer than expected so the compressor never shut off.

This fridge very well might be different, and maybe the fan is helping in your case, but you might want to check that video out so you have some things to look out for in case it’s causing other issues that you may not be thinking about.

Even if it was for batteries, unless we get fusion factors down to something that can fit in a car, power drill, smartphone, etc. batteries are still going to be a big part of the equation.

Sure, you can generate enough juice to power whatever you want, but only as long as it’s plugged in, anything that needs to get detached from the grid is still going to need batteries, and you probably don’t want your car hooked up to a 10 mile long power cord for your commute.

The issue people are worried about is that no one is making the decision to kill kids, it’s the AI making the call. It’s being given another objective and in the process of carrying that out makes the call to kill kids as part of that objective.

For example, you give an AI drone instructions to fly over an area to identify and drop bombs on military installations, and the AI misidentifies a school as a military base and bombs it. Or you send a dog bot in to patrol an area for intruders, and it misidentifies kids playing out in the streets as armed insurgents.

In a situation where it’s human pilots, soldiers, and analysts and such making the call, we would (or at least should) expect the people involved to face some sort of repercussions- jail time, fines, demotions, etc.

None of which you can really do for a drone.

And that’s of course before you get into the really crazy sci Fi dystopia stuff, where you send a team of robots into a city with general instructions to clear it of insurgents, and the AI comes to the conclusion somehow that the fastest and most efficient way to accomplish that is to just kill every person in the city since it can’t be absolutely sure who is and isn’t a terrorist

There was one team fairly recently that thought they had developed one that got a lot of press, but it turned out to not be true.

But that was only for that one specific case, it didn’t prove that room temperature superconductors can’t exist in general, there are still other teams working on developing them, and theoretically they could be possible, we just haven’t quite worked out what materials will exhibit superconductivity at room temperature, under what circumstances, and how to make them.

And we have some materials that come pretty damn close, Lanthanum decahydride can exhibit superconductivity at temperatures just a few degrees colder than some home freezers can manage (although at very high pressures)
