In other "incorrect calendars" bugs, there's the Rockchip RK808 RTC, where the engineers thought that November had 31 days, needing a Linux kernel patch to this day that translates between Gregorian and Rockchip calendars (which are gradually diverging over time).

Also one of my favourite kernel patch messages: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin....


My favorite: For one day all the Microsoft Zunes froze for the entire day, only to recover on their own 24 hours later when the infinite loop in their leap year code had finally resolved: https://web.archive.org/web/20090313105752/http://www.zunebo...

To be fair, that's nowhere near as daft as september, october, november, december. Latin for seven, eight, nine, and ten is: septem, octem, novem, decem. Those are the nineth, 10th, 11th and 12th months.

Edit: Whoops, correct eng -> latin nums


You may know this but originally they were 'correct' because the start of the year was March.

Which wouldn't be that weird, except that the earliest Roman calendar started in March and ended in December, having only 10 months!

The Romans were of course well aware that this left a gap of about two months between the end of one year in December, and the beginning of the next year in March. But they just didn't bother counting this period as part of the calendar year. Presumably because there was no agricultural reason to need accurate dates during winter.


AIUI, there is some confusion over whether this is actually the case. The pre-Julian calendar had 12 months, plus an optional intercalated month (they were aware that their ‘year’ had the wrong number of days, and periodically shoved in some extra time to patch it up). The 10 month calendar, if it existed, would have been very early and there’s not much hard evidence that it was actually used. Numa Pompilius, who was allegedly responsible, is a mythical figure and probably not an actual historical king.

Numa did try to name and consolidate the winter months, but it wasn't very popular.

The months were for productive seasons, winter for everything else.


Also French revolutionaries ;-)

I'm French and occasionally like to (re)read about the revolution period and every time I come to the calendar stuff I can't help but think "Really? This was stuff we wanted to spend time on?"

"I hate that SEPTember OCTOber NOVember and DECember aren't the7th, 8th, 9th, and 10th months."

"Whoever f---ed this up should be stabbed."

"I have excellent news for you."



We named the eighth month after a guy whose name was Eight, but October was taken so we called it August instead.

No? How is it octem and not octo? Does the flat bar accent do something?

>The Latin word for "eight" is octō. [0]

And indeclinable.

40 years since I studied Latin and a few glasses of wine and it was late ...

Good $3 MEMS gyros are about 100x better than that now - look at anything new made by Invensense in the past couple years. And their drift is pretty Gaussian-distributed, so the error scales as sqrt(n). If you combine 8+ of them on one board you can get about 5deg/hour stability...

I can't prove it either way, but it's pretty clearly LLM-generated slop!


What makes you think that so confidently?

It's not "standard professional practice". It's explicitly against Meta's TOS.


The irony isn't lost on me that it's the USA, the country with some of the most permissive gun laws in the world, that's imposing these draconian rules on 3D printed guns - or is this pressure from the gun manufacturing lobby?


Politically the US is very much not a monolith on this topic and many states and localities have passed laws that were later struck down as unconstitutional. This is a bill in California, which does have about the strictest laws that the federation allows them to have, and they would place even stronger restrictions on guns if they could. This is not really ironic as much as it is pushing the envelope for gun control as far as they legally can.

But also, California regulators likely see the regulatory landscape as the reason this law is needed rather than in spite of it.

Gun manufacturers are likely against these types of regulations because many of them would affect manufacturers and the tools they use too.


> strictest laws that the federation allows them to have

Note that "the federation" allowed states to have stricter gun laws until recently when we got a new partisan supreme court that is out of step with the previous 200 years of jurispudence.


It was confirmed for the previous ~130 or so, at least, since United States v. Cruikshank... although I certainly wouldn't want to go back to those days before the Bill of Rights were incorporated against state/local governments... Basically it was a blank check for racists to suppress minorities.

The result of United States v. Cruikshank was that southern states were allowed to to prohibit black individuals from owning firearms to defend themselves from the KKK. Not exactly a great example of gun control.

What's also crazy it is that it is also relatively recently that the first amendment was incorporated against states and localities as well.


> Gun manufacturers are likely against these types of regulations because many of them would affect manufacturers and the tools they use too.

No chance. For them compliance is the easiest thing in the world to law like that


Well, the NRA has come out against all of these proposed bills and has mentioned concerns about requirements that they may place on manufacturers.

The gun manufacturer's trade association has consistently said that 3D-printed "ghost guns" are more fantasy than reality, and that legal designs don't cause any more trouble than other legal guns: https://www.nssf.org/articles/3d-printers-cannot-produce-und... .


> is this pressure from the gun manufacturing lobby

Definitely not, it's pressure from the anti-gun lobby that keeps pushing "one more bill that this time will actually change violent crime statistics, we promise!"

These bills are being introduced in the states that already have the most restrictive gun control already, yet to nobody's surprise, hasn't done much to curb violent crime. But the lobby groups and candidates campaign and fundraise on the issue so they have to keep the boogeyman alive rather than admit that the policies have been a failure.


Ironically the anti-gun lobby seems to drive a lot of gun sales, perhaps it is not what it says on the tin?


I have three guns. One I inherited, two I bought right before California turned up gun restrictions. Possibly the greatest time for gun makers was when Hilary Clinton had a clear lead in the race for president.


A democratic governor/president is the greatest salesman for the gun industry. When a Dem is in office, the right wing comes out with all of the "they're coming for your guns" which is followed by a spike in gun sales.


The latter doesn't make the former untrue. There are plenty of people that want to eliminate all private gun ownership altogether, even if their public speech is more moderate.


I bought my three when I saw videos of the ATF under Biden start random "knock and talk" sessions for those who recently bought more than one firearm. They're all in a friend's gun safe as I have had bouts of depression, so I won't keep it in my home... I know it kind of defeats the purpose... but I'm very much a supporter of all of my civil rights, including and especially 2A.

I do some range days a couple times a year.


No conspiracy required. There's a lot of money to be made lobbying against guns - in the hundreds of millions of dollars a year - regardless of efficacy.


There are dumb arguments on both sides of this debate, but "one more bill that this time will actually change violent crime statistics, we promise!" is definitely one of the weaker arguments... pretty much all state-level gun control is worthless when there is no border control at state lines.


> states that already have the most restrictive gun control already, yet to nobody's surprise, hasn't done much to curb violent crime

The "most restrictive gun control" states in the US would still be generally by far the least restrictive gun control states in the rest of the developed world (you know, where gun-related deaths are a small fraction of here?).

Your answer smacks of "well, they tried and surprise surprise it doesn't work so why are we doing it?", i.e. "'No Way to Prevent This,' Says Only Nation Where This Regularly Happens".


Its just a political wedge issue in the US, its not really "about" guns anyway


It is hard to police guns when there is free travel between the US states, yet only individual states can be relied upon to pass any reform. A broken federal government means guns are easily exported from red states with practically zero gun laws to blue states where they are used to commit crimes. States are often forced to recognize rights granted by other states because such an interstate jurisdictional question naturally bubbles up to the aforementioned dysfunctional federal system.

Similarly to how many (most?) guns used criminally in Mexico actually come from the United States.

Edit: I'm not surprised by the downvotes, but I am amused. These are objective facts. Any basic research will yield many studies (including from the American government) showing that the majority of guns used in crimes in Mexico are traced back to the States. Americans love the boogeyman of dangerous Mexican cartels so much they never seem to ask themselves where these guns come from in the first place. Hint: look in the mirror.


> These are objective facts.

The characterization of the federal government as "broken" (at least in this capacity) and "dysfunctional" is a normative judgment you're making based on your own subjective value preferences.

Some -- perhaps most -- Americans regard the federal constitution's ability to restrain states from enacting policies that transgress against generally accepted individual rights as desirable, and working as intended.


That wasn't the objective fact in question, and I think you know that. A humorous one to contest anyway, given it is well known most Americans take a dim view of federal politics, especially when their favored party is out of power. This is a country where national elections are routinely decided by roughly a percentage point.

Are you willing to concede most guns used by criminals in Mexico come from the United States? That would be a question of fact, not characterization. And that, if it is easy enough to smuggle guns from red states into Mexico to commit crimes, it stands to reason it is even easier for red states to do the same to blue states? Or are you going to invent some other strawman to attack in your defense of your "individual rights"?


> Are you willing to concede most guns used by criminals in Mexico come from the United States?

No -- nor am I willing to assert the opposite, because I have no knowledge of the topic. I will ask, though: why is the place of manufacturer of guns used by criminals is Mexico something worth worrying about?

> And that, if it is easy enough to smuggle guns from red states into Mexico to commit crimes, it stands to reason it is even easier for red states to do the same to blue states?

Well, yes, of course. But I assume that this will be the case regardless of any attempted policy at any level of government, because I do not believe suppressing the movement of firearms is an attainable goal at any scale in the first place.


[flagged]


> Well maybe you should endeavor to get some knowledge? Yet it seems like you are saying it's irrelevant because you are uninterested in suppressing the movement of firearms, because it's not an "attainable goal". So really, you aren't interested in investigating this fact. That's fine, that's your business.

Yes, all of that is correct.

> Regardless of your own personal interest, it is a fact, and one you could confirm and learn more about rather easily.

I could, but I could also spend my time learning about many other topics which would yield useful insights, develop skills, help me understand the world better in ways that actually matter, among many other things. Why would I then spend time studying something for which the outcome would be the same regardless?

> So, if the best you can come up with is a more dressed up version of the other reply's "idgaf" well again that is your business.

Well, no, it's not just that I don't give a fuck, but rather that I think the entire line of inquiry is a waste of time in itself, in that all it will do is provide a rationalization for one normative position or another, and offers little utility to anyone beyond that. Arguing over it is like arguing over how many peanuts are in a particular jar -- yes, there's an objectively correct answer, but the question itself is of no importance, and not worth bothering to answer.


> A broken federal government means guns are easily exported from red states with practically zero gun laws to blue states where they are used to commit crimes

So why are the crime rates in most of these "red states" you are referring to often so much lower?

> Any basic research will yield many studies (including from the American government) showing that the majority of guns used in crimes in Mexico are traced back to the States

I couldn't give less of a fuck if this were true "research" or not: this isn't my problem, nor is it a valid reason to restrict my rights.

Also, please: a multi-billion-dollar criminal enterprise can't build or buy a machine shop and enslave or hire some machinists? They can build submarines and drones, but just couldn't possibly operate without US firearms? What reality do you live in?


The 10 states with the highest murder rates in 2024 were: Louisiana, New Mexico, Alabama, Tennessee, Missouri, South Carolina, North Carolina, Mississippi, Arkansas, Maryland.

Not seeing this so much lower crime rate in red states here.


>So why are the crime rates in most of these "red states" you are referring to often so much lower?

The welfare states have higher murder rates.


> hasn't done much to curb violent crime.

> they have to keep the boogeyman alive rather than admit that the policies have been a failure.

It's a documented, empirical fact that there is a marked correlation between common-sense gun laws and reduced rates of gun deaths.[1]

[1] https://everytownresearch.org/rankings/


Until knife killings start to rise (UK). Beyond this, I've seen several interventions of armed citizens stopping a crime in progress, when the police are still in route. When seconds count, the police are only minutes away.

My dad was ex-army, retired PD (detective, undercover) and a heavy 2A advocate. I grew up with guns around so it wasn't some weird, scary thing to see. I have many friends who also are heavy 2A who also grew up with guns in the home. It's first a matter of familiarity and second a matter of civil defense. I'm not a fan of "must flea" laws, and not a fan of restricting gun rights at all.

And yeah, if you can afford a tank and the ammo for it, as far as I'm concerned, you should be able to own and operate it. I would draw the line at nuclear weapons and materials.


I was with you until the whole tank thing.

Where's the line you're drawing between tanks + everything else up until nuclear weapons?


It is, in fact, legal (but very expensive) to own a tank ( https://www.drivetanks.com/ , yes, that's a company, but a rich enough motivated person could fill out the same paperwork). Apparently each exploding shell is a NFA taxed destructive device ( https://youtu.be/GW2U0qORdLE ).


Who do you think makes the tanks? It's typically corporations, but could just as easily be a person... It isn't a socialist/communist company doing the work.

It's pretty much already the case that people can have access to these weapons, I'm just being explicit.


"documented, empirical fact"

I won't try to make as strong a claim as the person you are responding to, but unfortunately, the politicized nature of the topic makes research on gun violence, especially as it relates to gun laws in the US, extremely fraught. The vast majority of research articles are plagued with issues. One should not just blanket trust the research (in either direction, and there are definitely peer reviewed journal articles pointing in different directions).

The claim you responded to was too strong, but for similar reasons, yours is also far far too confident.


Same thing with anything in regards to drug use in the United States. Dr Carl Hart talks about how hard it is to get anything that doesn't show harm published https://en.wikipedia.org/wiki/Carl_Hart


I'm responding to someone making assertions with zero cites, and I cite a source. If anyone has a cite showing that loose gun policies results in lower rates of gun deaths, they're free to present that.


I'm impugning the entire field of research, why would I then provide an opposing citation? My own claim should lead you to not trust it. I'm also not making any particular directional claim that would require such a citation.

I'm arguing that your statement, citation supported or otherwise, was stronger than I believe is warranted. You (correctly) criticized the original comment for making a stronger claim than they were able to support. You then technically did a better job in supporting your own claim (in the sense that you made any attempt to support it at all), but, in my opinion, you still made the same mistake of making a claim that was much stronger than warranted.


> My own claim should lead you to not trust it.

Your own completely unsupported claim?

No, that's not how it works.


I didn't say it was strong evidence or that one should just accept my claim, but regardless you have to agree it would be weird for me to say "the entire field is untrustworthy....but here is a paper anyways".


Your entire position is weird. The claim that there isn't a single source worth citing strains credulity. "That which can be asserted without evidence can be dismissed without evidence."


"there isn't a single source worth citing" is not my claim. It's that the field has a very high amount of highly politicized dreck and it can't be _generally_ trusted. I'm sure there are good citations. But one can't know if any particular citation is a good one without diving into the details (probably while having some degree of subject matter expertise), and any randomly selected article is more likely than not to be bad. As such, most people should not take the existence of a citation as proof of very much since it is more likely than not to be borderline useless. Especially given that the worst, most politically motivated articles (again: in both directions) are likely to be the ones that tell the strongest stories and have the least nuance and are therefore likely to be the most often cited.

This is an area where lay people should stay out of it, and should _definitely_ not be making strong claims like "documented, empirical fact" based on a shallow reading of someone else's summary of the literature.


I would dispute your source just by look at my own state, which has incredibly open gun laws, including free open carry and having had these laws since before anyone here was born, and a massive hunting population, and yet is claimed to be in the top half of strong gun laws. It is ranked significantly above Texas, and yet I know for a fact that my state has way more permissible gun laws than Texas, both historically and currently.

So I already know they are fudging the numbers, presumably because my state usually votes democrat and they want us to look good.

Hell its got Vermont as #17, but it has some of the highest gun ownership rates and most permissive gun laws in the nation.


"a source" - You "cited" the most left-leaning, well-funded anti-gun lobby in the United States. Is that who passes for a "source" these days?


Attack the source as much as you like, it's not refuting the point in any way.


Isn't the validity and credibility of the source critical to it being supportive of your argument? Seems like a reasonable counter-argument in my opinion.


I provided a source, and so far all those who’ve disagreed have only provided opinions. No one has cited anything that contradicts my source, so I don’t think it’s reasonable to say that the validity and credibility of my source has been impeached. ‘I don’t like it’ is not a valid criticism of a source.


No, you don't want criticism except on your own terms, but that's not the same as convincing people you are correct.


Not only the source, but the specific repoprting has been refuted already by others.

So you have failed to present an argument, and then continued to fail to support it. So all you have done is express an opinion. Those are fine and allowed, but of no significance to anyone else.


Do you have a source that isn't the anti-pickle alliance's statistics on anti-pickle laws proving why you should implement their anti-pickle laws?


"gun deaths."

You ever wonder _why_ they state the problem in such an abstract way?

It's because that statistic is an abstract itself. It combines, in my view inappropriately, suicide, murders, and accidental injuries.

There are 2x as many suicides every year over murders.

Anyone bandying about the "gun deaths" statistic has either been misled or is attempting to mislead others.


Not only that, the vast majority of gun related killings are with handguns, but they keep trying to outlaw the "scary" rifles.


The most common gun death is suicide so that tracks pretty well.

But I doubt most people count suicide as “violent crime”.


They do get included by anti-gun people who want to pump up the numbers. You can't trust anything but the government statistics broken out by type of death.


“Common sense” is a red flag for me. Obama (who I voted for twice, don’t come at me) pitched revoking second amendment rights for people on the Do Not Fly list as “common sense”. My common sense says we shouldn’t use a secret, extrajudicial government watch list with documented problems with false positives to revoke constitutional rights.


"Common sense" is an oft-used tactic in this space: if what I am pushing is common sense, whatever you are pushing is senseless.


Garbage methodology, state by state policies need to use something like a difference in difference study measure actual effect sizing


It's also a documented empirical fact that arresting the criminals in DC has reduced shootings to virtually zero.


https://www.criminalattorneycincinnati.com/comparing-gun-con...

Yet another lie by ommision. Violent deaths by guns have no relation to strength of gun laws. What your link measures is the number of accidental deaths by guns. If gun owners want to kill themselves it's not my job to keep them safe.


> If gun owners want to kill themselves it's not my job to keep them safe.

Not so fun fact, the person most likely to be killed by a gun in your home is you.

Some places deal with that reality head on, and it has an outcome that a lot of people are okay with.


Well, Canada is trying to keep guns away from you but is also perfectly willing to help you kill yourself.


> Not so fun fact, the person most likely to be killed by a gun in your home is you.

No shit: people commit suicide (which your "statistic" you lifted from Everytown, Giffords, or VPC - anti-gun lobbies includes.)

Suicidal people aren't a valid reason for my rights to be restricted, sorry.


> Suicidal people aren't a valid reason for my rights to be restricted, sorry.

You also have a right to travel around the country, but that doesn't mean you're allowed to drink and drive. There are plenty of valid, constitutional reasons for firearm ownership to be restricted to qualified individuals. When these restrictions are in place, many fewer people die. It is what it is.


According to the first militia act, every able bodied male over 18 is what defines a qualified individual. Beyond that, you're actually required to own a firearm in that case.


Can you show me where the right to drive a car is Constitutionally-protected?

Also, what a shitty analogy: suicide is by definition a self-harmful act, DUI is almost always a socially-harmful act on its own.

(And in many states, you can DUI on private property, by the way.)


> Also, what a shitty analogy: suicide is by definition a self-harmful act, DUI is almost always a socially-harmful act on its own.

"59% of people who died in crashes involving alcohol-impaired drivers in 2022 were the alcohol-impaired drivers themselves"[1]

Also, people who commit suicide with their firearms typically have families who suffer.

[1] https://www.cdc.gov/impaired-driving/facts/index.html


So are you advocating to outlaw alcohol? I mean, since people get depressed and drink which drives more depression and kill themselves... I guess you're suggesting that all depressants should be outlawed.


On the other hand, no one from the pro-gun camp is involved with or wants to involve themselves with drafting common-sense gun regulations to reduce the impact of mass shootings while respecting Constitutional rights. Everything from that side seems to revolve around arming schoolteachers and permitting more guns in more spaces.

So of course you're going to have wildly-overreaching proposals making it through committees and put to the vote, because no one from the other side is there to compromise with. Americans prefer to debate on the news circuit instead of the committee floor.


If somebody has a really stupid proposal -- such as "make all 3D printers refuse to print guns" -- I don't see why I have any obligation to "compromise" with them. Or to talk with them at all. Other than, perhaps, explain that they ought to learn about the things they want to regulate before they start making proposals. The fact that they have an incredibly long track record of bad proposals, and many strongly-held opinions based mostly in ignorance, is just entertaining.


You don't cooperate with abolitionists using compromise. You will never come to an agreement that satisfies both parties. By definition it is impossible.

Interests are also not always clear, any movement that wants to restrict activities using the law, is going to attract opportunistic power-seeking individuals. There's always crazy carve out exceptions in these proposals that allow the wealthy and the powerful to use and possess firearms that regular people cannot reasonably expect to have. It's laws to protect the powerful from the everyone else. Billionaires are creating armed doomsday compounds in countries like New Zealand, while supporting legislation that makes it harder to own a gun for self defense.

Also mass shootings are statistically the least likely cause of a gun related death. They are in the news because they are novel, not because they are likely to happen to most people.


I have an inalienable right to not be shot in public. So do my kids. The right to live should be paramount, far and above any excuses one might make about billionaires controlling all the guns.

Maybe we should enshrine that right in the Constitution as the Zeroth Amendment, because it is seriously being trampled as of late.


Unfortunately the constitution has never been the reason or means for protecting our rights. It is only an after the fact acknowledgement of them. It doesn't secure them, we do.


Indeed. Liberia had almost the same constitution.

Give a different or changing culture the same constitution, they can turn things into/remain a shithole very quickly.


Define "common-sense gun regulations", because every time someone tries explaining what that means it is almost always the exact opposite of common sense. Is restricting suppressors common sense? Because some of the nations with the most restrictive gun laws advocate for the usage of suppressors. Or bans on the scary AR-15, which is less powerful than most 60 year rifles which nobody cares about, especially when the vast majority of gun crime is committed with handguns. How about bans on gun accessories like types of stocks, slings, or bayonet lugs? How about sawed off shotguns which are less powerful than many "pistols" that shoot rifle rounds? Or shotgun/rifle combinations which were once a popular hunting combination for small game.

Either we should be allowed whatever semi-auto gun, or we should be allowed zero. Everything in between is a complete waste of time and effort and just leads to fucking over poor people for judicial profit because they can't afford $10,000+ lawyer that gets everybody with any money off of such charges.


Calling anything about gun control laws "common sense" is disingenuous at best. I'm coming at this from the "you go left enough and you get your guns back" side of the whole debate, but it's extremely difficult to solve a problem that consists of "tool used for its intended purpose, but in the wrong context".

Guns kill things. That's their primary purpose, it's why they exist. The people who aren't interested in guns for that purpose are easy to please: they don't really care about gun laws except in so much as they stop them from buying fun toys. They'd probably be fine with wildly invasive processes (being put on lists, biometric safeties, whatever), so long as they were given something in return. Something like, "You can have machine guns, but they need to be kept locked up at a licensed gun range".

People who just want guns for hunting are likewise easy to please. I'm not aware of any gun laws that have seriously effected the people who just want to shoot deer, because the tool you use to shoot an animal that isn't even aware you're there is pretty fundamentally different than those you to shoot someone who doesn't want to be shot.

The problem is people who want guns because of their utility against people, whether that means self defense, community defense, or national defense, fundamentally need the same things ( a need that is very expressly protected by the second amendment) as the person who wants to shoot a bunch of innocents. The militia folk might be fine with restrictions on handguns, but handguns are bar none the best choice for the self defense folk. The self defense folk might be fine with the existing machine gun ban, or other restrictions on long guns, but the militia folk need those for their purposes. The self dense folk are probably fine with being put on a list, but the militia folk who are concerned about the holders of that list are rightfully opposed to that.

IMO, the most effective gun law that isn't a complete non-starter to any legitimate groups of gun owners is the waiting period. It's an effective policy that substantially reduces suicide. That's a good thing. Requiring sellers to not sell to people under 18, or those who are obviously a threat to themselves and others is also largely unobjectionable. Punishing parents who fail to secure their weapons from their children, also a good thing.

No one's in favor of mass shootings, but it's not anywhere as simple as saying "common sense gun regulations".


Regarding your statement about the guns used against animals being different than the ones used against people is just wrong. The AR-15 is about the perfect choice against wolves or wild boar, just as a single example.

As far as the waiting period, there's a perfectly valid reason against that as well... if you are under eminent threat of violence from someone and want to be able to defend yourself/family/home today... it stops you from being able to do so.

I am okay with the (relatively quick) background check... when I bought my first guns a few years ago, I had to wait about an hour in the store for the results to come back (Phoenix). Even then, I'm not okay with secondary offense restrictions (weed, etc) as a restriction.


> IMO, the most effective gun law that isn't a complete non-starter to any legitimate groups of gun owners is the waiting period. It's an effective policy that substantially reduces suicide

If I own many firearms already, what exactly does a waiting period do besides infringe upon my rights?


If you own many firearms already, how is a 30 day wait preventing you from bearing them?

But yeah, the benefit does mostly arise for first time gun buyers. But that would require a master list of all gun owners. I'd prefer the wait per gun.


"A right delayed is a right denied" (*except when it's a right protected by the Second Amendment, I guess.)


"doesn't matter how many schoolchildren die if I can't buy my weapon right away"


Which "schoolchildren" died because of a firearm that was purchased inside of a 30 day window? None of the famous massacres would fit this bill; did you have an actual, documented event in mind or just feelings?

All of the gun grabbers I am aware of that are in favor of waiting periods try to make this infringement justified based on "crimes of passion" and other "heat-of-the-moment" nonsense - not "schoolchildren."


It's just an example, you're refusing any kind of gun regulation, doesn't matter what it is, dead kids is not a factor.

Casual gun ownership is the difference. In Europe you can get guns, but you do it for a purpose like hunting or sports, license and training is required.


They don't have any evidence because they are appeals to emotion.

If you look at the people doing the shooting you get a much better correlation but no-one wants to go there.


No evidence? Just look at Europe or Australia.


the places where they put you in prison for tweets ?

In the US one of the best demographic predictor of homicide rates is skin color. For instance, super white places like New Hampshire with the ~loosest gun laws in the country have extremely low murder rates.

If you take a look at say a heat map of the US where homicide is[1], it tracks extremely closely to where the black population is (New Mexico an outlier despite having stronger gun laws than most the surrounding states besides Colorado).[2]

What's also fascinating is that this metric is consistent even when controlling for socioeconomic status - ruling out "unfair circumstances! less opportunities!" arguments.


I'm not suggesting it, I'm asserting it.


Would you be okay with a 30 day waiting period for posing a news article, that included strict penalties for misinformation/disinformation? Since you have to wait to publish, you have less reason to get things wrong.


A 30 day waiting period on news articles doesn't meaningfully reduce actual suicides. One on guns _does_, without a corresponding harm to the buyer.


A 30-day waiting period on news articles _should_ meaningfully reduce misinformation. A lot of lives are ruined by misinformation/leaks in early news articles that are later disproven and those retractions are rarely covered as widely as the original false news.

I'm talking about saving people's lives here.


> I'm not aware of any gun laws that have seriously effected the people who just want to shoot deer, because the tool you use to shoot an animal that isn't even aware you're there is pretty fundamentally different than those you to shoot someone who doesn't want to be shot.

If you talk to hunters, they'll give you a long list of annoying laws.

California requires a background check to buy ammunition and prohibits state residents from importing ammunition. If you are a non-resident, you can bring ammunition in, but you cannot give it to your hunting buddies and you cannot buy ammunition in California. This is such a common problem that many hunting organizations have guides explaining the issue.[1] When I lived in California, I was unable to buy ammunition despite legally buying several firearms. Around 1 in 6 legal gun owners in California are incorrectly denied when purchasing ammunition.

California (along with several other states) bans civilian ownership of silencers. Hunters need to be able to hear when searching for game, and they rarely have time to don hearing protection before taking a shot. So the net effect of this restriction is to give hunters hearing damage and create more noise pollution. It's also a problem for anyone in rural areas who wants to dispatch pests, as gunshots annoy neighbors and can even result in the police being called.

California requires that long guns be unloaded when transported, but the definition of "unloaded" states that ammunition be stored separately. If ammunition is readily available near the firearm, California counts that as loaded, and you are committing a crime. If you have cartridge holder loops on your rifle's stock, they must be empty during transport even if the firearm is in a locked case.

California requires that hunters use lead-free ammunition. Lead-free ammo is more expensive and less available than typical lead ammunition, especially if you're not hunting with a common caliber. Many hunters zero their rifle using leaded practice ammo, and are generally less experienced with their hunting ammo. This makes hunters more likely to miss an animal's vitals, prolonging its suffering. Lead-free birdshot makes sense, but considering how few rifle rounds are expended while hunting, and how it's legal to use leaded ammo for target shooting in the wilderness, the lead restriction on rifle ammo serves no useful purpose.

It's been years since I lived in California, so I'm probably forgetting some other laws that annoy hunters. But believe me: hunters are not happy with the current laws.

> The irony isn't lost on me that it's the USA, the country with some of the most permissive gun laws in the world, that's imposing these draconian rules on 3D printed guns - or is this pressure from the gun manufacturing lobby?

It's like saying "I am baffled by Europe, look at what Hungary is doing ..."

For example, some states don't need any permit to open or conceal carry, some have no minimum age requirements to buy guns, and the majority don't have any mention of 3D printed guns.

Federal law applies then about untraceable guns and or arms that cannot be detected by metal detectors. But those predate 3D printers as we know them today.


It's not the most "permissive gun laws in the world". In Norway you can buy a suppressor off the shelf with little to no paperwork.

If you live in CA and don't want to experience permanent hearing damage from shooting, you'll catch a Felony for simply possessing one. It's a big middle finger like the rest of California's gun laws.


I'm pretty much a gun control maximalist, but I would be more than happy to barter suppressor restrictions for pretty much anything else, since I agree with you that there's a good non-shooting-other-people reason to want to have them and I doubt they're actually that relevant to murder stats.


I mean on Amazon you can buy them too, you just might have to look for something like a "lawnmower muffler for 9mm exhausts".


That’s a felony everywhere though


Sure, if you're a big fan of getting your dog shot and yourself thrown in federal prison for 10 years.


I think the current government of California would significantly regulate firearms if they could. It’s prevented from passing more restrictive laws due to the US constitution and a Supreme Court which takes an extremely broad interpretation of the rights derived from the second amendment.


In the US there is a certain class of politician that considers poor people being able to exercise their rights a problem that needs to be solved.


Is that really limited to the US though?


It is both the USA and California. California doesn't allow most guns that other states allow and there is a lot of friction between CA and the USG.


This is a reaction to the inability to accomplish anything at the federal level in the "we have to do SOMETHING" vain.


^ This. The Feds are so utterly gridlocked in culture war nonsense and whatever dumb bullshit Trump is up to that they cannot effectively govern. States and activists groups are trying to address actual problems the country has, instead of just playing political games on Twitter.


Ah yes, the actual problem facing America right now... unsanctioned 3d printers.

Thank you California for acting on this, our top national priority.


To be fair, the CEO of UnitedHealth Group was murdered with a 3D-printed handgun. He made $10 million in 2023, or about 100 times the median salary of a UnitedHealth employee.


More people have been murdered with sharpened sticks. I'm eagerly awaiting the anti-whittling laws.


Yes, but this murdered person was important, you see.


You can make a gun with a piece of pipe and a nail. It's performative legislature.


This bill is performative legislature not because of pipes and nails, but because professionally manufactured guns are widespread in the US. Criminals in the US overwhelmingly choose this option.

Criminals have tons of options, including straw purchasing a CA compliant gun, straw purchasing a non-CA-compliant gun from Nevada, or just throwing a brick through the window of the nearest pickup truck with a Glock sticker on it.


The actual problem is gun violence which you absolutely, 100% know.


Which this bill will do nothing to solve, which you absolutely 100% know.


I know no such thing. The number one type of gun death is by far, suicide. When a gun owner takes a gun home (or in this case, prints one) statistically speaking they are more likely to use it to end their own lives or harm themselves more than anything else.

You could make a similar case for this as was made for the banning of highly toxic coal gas in the UK in the 1960's. Most suicides are acts of distressed individuals who have quick, easy access to means of ending their own lives. The forced changeover from coal gas to natural gas is largely credited with a reduction of suicide by 40% after it was done. https://pmc.ncbi.nlm.nih.gov/articles/PMC478945/

I don't think 3d printed guns have been around long enough to really provide meaningful data on whether this law will be effective, and on the whole, I'm not thrilled about it. But again, as was originally commented: this is an issue where states are, perhaps ineffectively and ineptly, attempting to solve what they see as problems, under a federal government that has shown itself incredibly resistant to common sense gun regulation that virtually everyone, including the gun owning community, thinks is a good idea.


> The forced changeover from coal gas to natural gas is largely credited with a reduction of suicide by 40% after it was done.

The mechanism of that reduction very well could be reducing the level of depression in the populace and thus suicidal ideation, rather than just making the means less handy (or of course, some combination). Coal gas, like any other gas used for combustion, doesn't burn perfectly and UK homes likely had persistent amounts of carbon monoxide roughly all the time since heat gets used not-quite-year-round.

From https://en.wikipedia.org/wiki/Carbon_monoxide_poisoning#Chro... :

> Chronic exposure to relatively low levels of carbon monoxide may cause persistent headaches, [...], depression [...].


> statistically speaking they are more likely to use it to end their own lives

What historical precedent is there for infringement of Constitutionally-enumerated rights of others based on suicides?

Why is this somehow a "gotcha" that would justify these infringements, in your mind?


> What historical precedent is there for infringement of Constitutionally-enumerated rights of others based on suicides?

There is no requirement that a precedent exist for limiting personal freedoms for the sake of safety. We infringe personal rights in the name of public safety all the time, not the least of which is current, existing gun regulations, all the way down to far more benign shit like speed limits, and not letting people scream "fire" in a theater. The 2nd Amendment was itself a modification to the constitution, ratified some time after the constitution itself. Hence the "amendment" part.

And as numerous gun activists have pointed out before me: The individual ownership interpretation goes only back to the 2008 ruling in District of Columbia v. Heller, and is not itself law, merely judicial precedent. The right for every single American to own a gun is not enshrined in any law, merely an interpretation of a law, and the law itself was written in an era of single‑shot, muzzle‑loading firearms, not modern semiautomatic rifles, and further, it was written to promote the creation of, and I quote, "well-regulated Militas," not "Ted up the street who owns the gas station."

Further, even if it was spelled out, in the 2nd Amendment, in clear words, that every single American had the innate right to buy and use an AR15, that does not make it unimpeachable or forever carved in stone: We can change that. We can amend the amendment, hell, we could reverse it entirely. The problem of gun violence is a hard nut to crack, and the culture of American gun ownership is long standing and on the whole I myself quite like guns. That said, I think they're far too easy to get right now, and I am far from alone in that opinion.


As far as I understand it, yelling "fire" in a crowded theater has not actually been legally tested. This was a non-binding analogy used in the decision of a supreme court case that found it was not a violation of the 2nd amendment to prosecute someone for speaking out against the draft (which was later overturned for obvious reasons).


The "fire in a crowded theater" line is by Justice Oliver Wendell Holmes, Jr. in Schenck v United States.[1] During the first World War, he ruled that it was constitutional to send socialists to prison for distributing leaflets that protested the draft.

The judicial precedent set in that case was overturned in Brandenburg v Ohio.[2]

1. https://en.wikipedia.org/wiki/Schenck_v._United_States

2. https://en.wikipedia.org/wiki/Brandenburg_v._Ohio


The fact that the federal government is unwilling to restrict guns and other real causes of ongoing public health crises (such as massive passenger cars and trucks) even as the deaths pile up does not mean that any level of government should be piling onerous regulations onto other things that demonstrably cause essentially zero harm at the macro scale, such as 3D printers, non-commercial/non-military UAVs, and so on.

If the number of people killing themselves with 3D printed guns is not literally zero or vanishingly small at most, I would be very surprised.


> that's imposing these draconian rules on 3D printed guns

This is a bill with no votes - the first committee hearing is in March.

The purpose of the bill seems to be have some controversy & possibly raise the profile of the proposer.

The bill is written very similarly to how we enforce firmware for regular printers and EURion constellation detection.


It’s pressure from the anti gun obsessed nonprofits on the left like Everytown. Bloomberg has nowhere else to waste money and there are legislators willing to present bills authored by Everytown blindly. But in many cases gun control bills are known to be unconstitutional and pushed through anyways. It takes years for laws to be ruled unconstitutional by the Supreme Court and even if they are, states like Washington or California or Oregon will just pass the next Everytown authored unconstitutional bill with a slight variation.

The real fix is that we need to get rid of immunity for legislators. When they violate the civil rights of the constitutional rights of citizens through their actions, they must be held personally liable and must go to jail.


If by "the left" you mean the DNC, then sure. Otherwise, Marxists, Socialists, and other far left groups are perfectly fine with guns. Hell Vermont has some of the highest gun ownership rates and most permissive gun laws in the nation, while having Bernie Sanders as a senator.


> The real fix is that we need to get rid of immunity for legislators. When they violate the civil rights of the constitutional rights of citizens through their actions, they must be held personally liable and must go to jail.

Why are you so angry about this?


If someone prevents you from exercising your right to vote, would you be angry?


This only benefits expensive proprietary enterprise 3D print makers..


It's the anti-gun lobby. Bloomberg's band of morons who believe a government monopoly on force is good.

These bans are almost exclusively in states with already extremely strict (high rated by the gifford's law people) gun laws.

So far, there is zero evidence in the last 30 years more strict gun laws have curbed crime. The states with the strictest laws conveniently have the highest proportion of gun crime. The same people writing these laws don't understand what "per capita " means. Nor are they willing to confront the reality of what the data shows. The calculus for these petty tyrants has changed from banning guns wholesale to lawfare. Make owning and purchasing firearms so burdensome the market dies, and with it, the rights. This is just another play in that strategem.

Fun fact: More people died last year putting foreign objects in their rears than by AR-15s. That is how insane the anti-gun lobby has become. They are literally barking at their own shadow these days.


No amount of FBI stats about how often "assault" rifles are used will change people's minds. They don't like them and so want to take them away.

I don't know how to square the same people saying we're living under a tyrannical government also pushing legislation that makes sure said tyrannical government is the only one with guns.


I can't square people who think owning a gun will stop or prevent a tyrannical government. Especially when the tyrannical government just leverages its supporters as a vigilante force.


An armed populace creates a huge risk for a federal paramilitary force descending on a municipality with the intent to terrorize the citizens. They're not rolling in with tomahawks and tanks, they're coming in with assault rifles and window breakers.


It won't "stop" them but having to treat everyone like they might shoot back and show up with a 10:1 manpower advantage and armed to the teeth every time you wanna subject someone to state violence really puts a damper on your ability to do tyrannical government things.


The current time period is not proving that out. These are just ammosexual fantasies.


Not at all true. I haven't yet witnessed armed resistance to ICE, but it's in the cards, if the government wants to push. Given the number of veterans and folks that actually have skill with guns in the civilian populace, and the hiring standards of ICE, I think the civilian population, properly mobilized, would be incredibly effective at putting a damper on their illegal behavior.


Have yet to see that so I'm not putting stock in a hypothetical armed uprising.


It's an extremely dangerous line to cross, and it should be avoided if at all possible. At the same time, when no other options are available, it's better to be armed than not. I hope you never have to learn this first-hand.


It kind of is in that they're picking the easy targets. They're not being sloppy in places where wrong address has an unacceptably high (but still small) chance of having them confused for the DEA and shot back at by someone who isn't going to prison one way or another.


The problem with that thinking is that you have to have the will to act to stop tyranny, and no amount of armament will give you the will or the foresight to see it.


> So far, there is zero evidence in the last 30 years more strict gun laws have curbed crime. The states with the strictest laws conveniently have the highest proportion of gun crime. The same people writing these laws don't understand what "per capita " means. Nor are they willing to confront the reality of what the data shows.

I’ve seen this claim from a few people in this thread but everytime I look up gun deaths per capita Massachusetts and California are low on the list and both have strict gun laws compared to red states


Do you have a reference or at least some hard numbers for your "fun fact"?


Long gun homicides (justified and unjustified, "assault weapons" and grandpa's 30-06 combined) are typically sub-500 per year, see: FBI crime stats for the last N decades.

Pick whatever demise: falling off of ladders, roofs, etc. - it's not hard to exceed this number in any given year.


Can you redo your "fun fact" but include all types of guns?


Pew does what they can:

> In 2023, the most recent year for which the FBI has published data, handguns were involved in 53% of the 13,529 U.S. gun murders and non-negligent manslaughters for which data is available. Rifles – the category that includes guns sometimes referred to as “assault weapons” – were involved in 4% of firearm murders. Shotguns were involved in 1%. The remainder of gun homicides and non-negligent manslaughters (42%) involved other kinds of firearms or those classified as “type not stated.”

Interesting findings:

Most gun deaths are suicides with handguns.

Assault weapons are used in less than 5% of deaths.

Handguns account for 53% of the deaths.

Shotguns are negligable.

https://www.pewresearch.org/short-reads/2025/03/05/what-the-...


So basically the comparison to foreign body objects (of any type) to a single type of gun- which represents a tiny fraction of all gun deaths- is not a convincing comparison.


The point was that all the regulation on assault weapons doesn't have a meaningful effect. At best, you could reduce gun violence by 4%.

I wouldn't over-rotate on the comparison to foreign body objects: the point is, if you rely purely on the media to inform you about gun violence, you're going to get a funhouse mirror version of reality. It's way more exciting to write about the 40 school children killed in the last two years in mass shootings than the 16,000 depressed dads that blew their heads off in their garage with a handgun in the last 12 months (spitballing a bit, but 40,000 deaths, 50% of which are suicides, 80% of those are men).


I disagree- this subthread was not about assault weapons, it was about gun-control laws. But yes, if you limit yourself to assault weapons (itself a somewhat nebulous term that just muddies the discussion IMHO), then yes, you're not going to have a huge impact.

No argument that the media produces inaccurate representations about guns. I spend a fair amount of time reading articles and also spend a lot of time reading into the facts that they report.


Upvoted; I think this is a case where we are genuinely focusing on different aspects, and I see your point. My concern is that laws are often too performative. There's probably a lot to discuss there, but I suspect we largely agree.


Well there is a lot of weird focus on entirely the wrong things when criticizing guns.


Your fun fact is misleading because it's specific to AR-15s. A better comparison would be all types of guns.


It's mostly the same Karens that want to outlaw guns altogether so come up with burdensome rules to inhibit gun ownership. I've always been pretty libertarian on 1A and 2A myself.


It is pressure from the gun control lobby. Everytown for Gun Safety, a gun control group, is the brains behind it. The states moving this legislation (California, Washington) are very hostile to gun ownership, and already have bans on assault rifles and printed guns. This is just another step in tightening the noose.


It's important to note that the USA also has some of the fiercest opponents of private gun ownership in the world.

The most important thing to note here is that a majority of the support for gun control in America is cultural. Even the loud-and-proud pro-gun people got extremely shy about their own principles once the Black Panthers started packing heat. On the flipside, it's also not hard to find gun control supporting Democrats that happen to own firearms in their house. There's a related cultural argument over "assault weapons", or "black guns" - i.e. the ones that look like military weapons rather than hunting tools.

The result of all this confusion - and, for that matter, any culture war fight - is a lot of stupid lawmaking designed specifically to work around the edges of 2A while ignoring how guns actually work or how gun laws are normally written. Like, a while back there were bans on purely cosmetic features of guns. Things like rail attachments, that do not meaningfully increase the lethality of the weapon, but happen to be preferred by a certain crowd of masculinity-challenged right-wingers. In other words, a ban on scary-looking guns.

What's going on here is that someone figured out how to make a 3D printed gun that will not immediately explode in your hand on first firing. In the US it's legal to manufacture your own guns, and there's no requirement to serial-number such a gun, which makes it more difficult to trace if that gun is used to commit a crime. You can't really stop someone from making such a "ghost gun" (practically, not legally), so they want to take a page out of the DMCA 1201 playbook and just ban all the tools used to make such a thing possible.

Personally, I don't think that will pass constitutional muster - but that also relies heavily on existing culture-war brained nonsense that happens to be standing constitutional principle. 2A itself can be interpreted in all sorts of different ways. The original interpretation was "no interfering with state-run slave catching militias", and then later that turned into "everyone has the right to own firearms". Nothing stops it from changing again.


No, this is probably an illegal CA law.

I'm a strong believer in 2a rights. However I think every type of weapon might require a license. So if you 3d print a gun that you would be allowed to own if you had already completed your background check, then you're gold.

If you end up 3d printing a nuclear bomb, the licensing requirements for that would be a billion times harder. (secure facilities, 24/7 guards, blood oath to the United States etc...)

They’re more American than whatever the fuck you are to have that thought


They've taken it down now and replaced with an arguably even less helpful diagram, but the original is archived: https://archive.is/twft6


Wow it’s even worse than I thought. I thought that convictungly morhing would be the only problem. The nonsense and inconsistent arrowheads, the missing annotations, the missing bubbles. The “tirm” axis…

That this was ever published shows a supreme lack of care.


The turn axis is great! Not only have they invented their own letter (it's not r, or n, or m, but one more than m!), it points the wrong way.


Lots of the AIisms with letters remind me of tom7's SIGBOVIC video Uppestcase and Lowestcase Letters [advances in derp learning]

https://www.youtube.com/watch?v=HLRdruqQfRk


It's like the Pokémon evolution of n through m, we need to notify the Unicode Consortium.


And that's what they dared to show to the public. I shudder thinking about the state of their code...


It really is wild / telling how fundamentally AI can screw up what seems like just basics like ... an arrow.


Is it truly possible to make GitFlow look worse than reality?


This passage from the post by the original creator of the diagramme summarises our Bruh New World:

"What's dispiriting is the (lack of) process and care: take someone's carefully crafted work, run it through a machine to wash off the fingerprints, and ship it as your own. This isn't a case of being inspired by something and building on it. It's the opposite of that. It's taking something that worked and making it worse. Is there even a goal here beyond "generating content"?


That reminds me of the (earlier) Apple and people saying that Apple just copies from the competitors. Well, they took the good parts and improved the bad parts. That's the excellence level you can achieve when copying.

This here is just so cheap, I would not even dare to call it a copy.


Apparently the new diagram is now a rip off of another one from Atlassian: https://bsky.app/profile/vurobinut.bsky.social/post/3mf52hmw...



It looks like typical "memorization" in image generation models. The author likely just prompted the image.

The model makers attempt to add guardrails to prevent this but it's not perfect. It seems a lot of large AI models basically just copy the training data and add slight modifications


Remember, mass copyright infringement is prosecuted if you're Aaron Schwartz but legal if you're an AI megacorp.


> It seems a lot of large AI models basically just copy the training data and add slight modifications

Copyright laundering is the fundamental purpose of LLMs, yes. It's why all the big companies are pushing it so much: they can finally freely ignore copyright law by laundering it through an AI.


> It seems a lot of large AI models basically just copy the training data and add slight modifications

This happens even to human artists who aren't trying to plagiarize - for example, guitarists often come up with a riff that turns out to be very close to one they heard years ago, even if it feels original to them in the moment.


TIMMMAYYY


This kind of thing, widely implemented, would be a game-changer for dealing with assets after someone's death! I maintain my family's IT infrastructure (Google Enterprise admin, webserver etc) and I've been tempted to write down 1/4 of my password manager root password and give it to each of my family members - but then we run into the problem where if any one of them loses their shard, it's unrecoverable. Some kind of ECC would be great - ideally where I could print it out onto various bits of paper with a user-definable redundancy, or better still, some kind of reciprocal system where (say) 8/10 members of a trusted friend group/family ring could unlock any other member's password...


Don't worry even if your heirs have the password, it's extremely likely that Google will find the login attempts "suspicious" and try to verify your identity by sending SMS codes to a phone number you last had in 2005, despite your best attempts to prevent it.


Shamir secret sharing is the cryptographic thing that you want. You can can configure any M of N to be needed to recover the underlying secret.

(If you have a trusted third party, you can also enforce a cooling off period: e.g. that any attempt to access results in a notification to the account holder that if not denied within some time period, access is granted)


Something along the lines of reed-solomon codes could work for you:

If you want to share your password with M family members such that you only need N to agree to recover the original:

Split your password into ordered chunks.

Make a polynomial p, of power N where the p(1) = chunk1, p(2) = chunk2, ...

Evaluate the polynomial at M other points: p(N+1),p(N+2)...

Gives those M new points to your family along with their index (+1,+2,...).

If less than N family members get together, they will not be able to figure out the password much better than guessing. If N get together, they can interpolate their points to form the unique polynomial which will match p. Then evaluate p at p(1),p(2),... to get your original password.

If you put the whole password into 1 chunk, and pad the polynomial with random extra coefficients or points to make the polynomial of sufficient degree, then they get literally no information on the password without having at least N cooperate. If you make multiple chunks then they can do a little correlation between the chunks without knowing the whole thing.

This is sufficiently simple you can even work this out by hand without a computer, though it would be somewhat tedious.


Reed-Solomon is error correction, not encryption.


Reed-Solomon and Shamir secret sharing are quite similar (even though in practice they're used for very different things).

"Do not roll your own crypto" though.


There are much better systems for splitting data than just chunking it into N chunks, the most common is Shamir Secret Sharing[1] (the main benefit being that you can construct an M-of-N scheme easily and having N-1 shards provides you zero information about the secret). One word of caution -- a lot of software developers get enamored by the idea of information-theoretic security when they first run into it, but you eventually realise that useful applications of tools like SSS are actually quite rare.

Shameless plug: I wrote a project a few years ago to create PDF-based backups with sharded keys which would do exactly what I suspect you want[2], unfortunately I got stuck at the "make a nice UI for it" stage (everything works but it's just a CLI tool at the moment). I guess I should take a look at using an LLM for that these days... (I used this to store my password manager root password and necessary keys to pull and decrypt the encrypted backups of my server.)

[1]: https://en.wikipedia.org/wiki/Shamir%27s_secret_sharing [2]: https://github.com/cyphar/paperback/


A quarter of your password manager's password means it needs to be really long for it to not be bruteforceable if one or two quarters are recovered (on the order of at least 24 completely random alphanumeric characters)

Shamir's secret sharing scheme does not allow anyone to bruteforce it, no matter if they have 99 out of the 100 required pieces that unlock a 10-character password. If you want to do this sort of thing, I would recommend using a secret sharing scheme instead


We care about this porblem and are actively working on it, like the OP we also settled on shamirs secret sharing with a time lock mechanism.

However, there is still the issue of the service provider going offline or out of business which we don't have a solution for yet.

We have started with a good password manager and will be adding digital inheritance/social recovery soon! [0]

Take a look, thoughts and feedback welcome.

services going offline is a big concern for me! that's why my solution is offline first, I like the idea of the encrypted backup living in my friend's email inbox and working entirely without internet. a true hard copy.

for the time lock mechanism, how do you go about it? I'm interested in exploring using drand time lock, but that also relies on the service continuing to run (which is admittedly very likely) https://github.com/drand/tlock


You can give your password, or part of it, to your estate lawyer to attach to your will.

This is obviously more cumbersome, and probably costly, if you intend on changing your password. I guess you could change the part of it you don’t store with them.


yes! I am starting to do some planning on that myself, that's why I'm in that kind of mindset. If you know more people in this space, please share this with them! would love to get feedback


I wrote a project to do this a few years ago[1], it's mainly missing an automated mechanism to scan the PDFs and a GUI. Maybe you'll find it interesting.

[1]: https://github.com/cyphar/paperback


hey, this is a great idea! I'll link into your app from my readme. I really like that the PDF contains the entire dataset, not just the keys. I see lots of little details around organizing the PDFs, like document hashes, etc, very nice job!

Since you wrote it in Rust, I'd suggest compiling it to wasm and releasing a browser-based version


> Since you wrote it in Rust, I'd suggest compiling it to wasm and releasing a browser-based version

That was my eventual plan for having a single GUI for everything, the only problem is that there isn't a really obvious way to support scanning a PDF you upload -- basically you need a pure-Rust PDF renderer and there isn't one up to the task as far as I could tell. On mobile you could scan each QR code separately (though doing this from a webapp is probably going to be a fairly awful UX and most people would prefer to photograph the whole document and get everything scanned automatically).


use the webcam, you put the QR in front of the webcam, there has to be a library for this


Actually, after my comment I took another look and it turns out that only a few months ago someone released a pure-Rust PDF renderer called hayro[1] that seems to fit exactly what I need, so I will work on finishing this bit of paperback as soon as I have some spare time. Pure image scanning (with a webcam, phone camera, or uploading a photo) will also work since QR code scanning libraries like rqrr support scanning all QR codes in an image.

A lot of tests are designed as regression prevention. You know the system is working as designed, but what if somebody comes along and changes the Fibonacci function to compute much more efficiently (and, in the process, makes some arithmetic errors?).


My favourite one of this kind is the Rockchip RK808 RTC, where the engineers thought that November had 31 days, needing a Linux kernel patch to this day that translates between Gregorian and Rockchip calendars (which are gradually diverging over time).

Also one of my favourite kernel patch messages: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin...


It's always November, isn't it? I've once made a log collection system that had a map of month names to months (had to create it because Go date package didn't support that specific abbreviation for month names).

As you might've guessed, it lacked November, but no one noticed for 4+ months, and I've left the company since. It created a local meme #nolognovember and even got to the public (it was in Russia: https://pikabu.ru/story/no_log_november_10441606)


That's gold.

That hardware real time clocks keep time in date and time drives me batty. And no one does the right thing which is just a 64 bit counter counting 32khz ticks. Then use canned tested code to convert that to butt scratching monkey time.

Story my old boss designed an STD Bus RTC card in 1978 or something. Kept time in YY:MM:DD HH:MM:SS 1/60 sec. And was battery backed. With shadow registers that latched the time. Couple of years later redesigned it as a 32 bit seconds counter. With a 32khz sub seconds counter. Plus a 48 bit offset register. What was a whole card was now a couple of 4000 series IC's on the processor card. He wrote 400 bytes of Z80 assembly to convert that to date and time. He said was tricky to get right but once done was done.


I would guess that’s because those chips were designed for use in systems that didn’t have a CPU, but reading the data sheet, it doesn’t look as if you can easily hook up this thing to 7-segment LEDs, so maybe this is a matter of “this is how we always did it, and if it ain’t broke, don’t fix it”, and then ‘fix’ it, anyways?


I had some interactions with the guy responsible for the code that made our system do the right thing around Daylight Saving. Listening to him talk out loud as he thought about bugs was fascinating. He was clearly one of the smartest people I've met and I would quickly fall behind as he rationalized problems to himself. What a marvelous mind.


Some of them do have an epoch counter in addition to broken down time.


The Renesas RTC divides the 32khz clock by 256. And after waking up doesn't update the shadow registers till the next tick. So if you wake out of deep sleep you don't know what the time is for 8ms.

I know of one that draws 0.5uA in normal mode but 12uA in binary counter mode.


I propose naming the code that ensures this 8ms has elapsed "the yawn".

But to be fair, it doesn't seem that onerous an issue - the biggest problem would have been if this was completely undocumented. One obvious workaround is to read the time immediately on wake up, and then ignore the result until reading the time returns something different.


That one is up there with the all time greats.

>.< haha i remember this


And price. A PY32 is about $0.08 in quantity and can do a lot more than a 555 - which is at least 3 times more expensive...


and it comes with new set of problems: Now you need a FW guys to write and maintain software for it, then your hardware team may need to wait that FW guy to release software to test, or the FW guy need to wait hardware to test his software, etc.

Then in production, you need another stage to flash the FW, which add time and complexity.

Then security, cheap MCU usually has bad software protection, that means your software can be read out easily, not a big deal since the FW replacing the 555 would be dead simple anyway, but try to explain it to a non-technical CEO when he read about it on his morning's newspaper.


Puya? First time I hear of these things .. (having used ESP32, RPI Pico, Nordic and STM). Googling led me to OpenPuya https://py32.org/en/


Puya is a major flash manufacturer who ventured into ARM chips.
