- Comment on What realistically would happen if someone came back to life from the dead ? 1 week ago:
A few months ago, we had a question about what would happen if necromancy was possible and an undead was called as a court witness. I gave a rather fun-to-write, tongue-in-cheek answer, which might be germane to your question too. Here’s just a snippet:
So now we come back to zombies. Would a jury be able to set aside their shock, horror, and awe about a zombie in court that they could focus on being the finder of fact? If a zombie says they’re an eye-witness to a mugging, would their lack of actual eyeballs confuse the jury? Even more confusing would be a zombie that is testifying as an expert witness. Does their subject matter need to be recent? What if the case needs an expert on 17th Century Parisian fashion and the undead is from that era and worked in haute couture? Are there no fashion historians who could provide similar expert opinions?
- Comment on Can someone explain to me how a ventilation fan can suck LESS when on high compared to low? 1 week ago:
Constant Speed is probably what I was thinking of. And speaking of multi engine failure, you’ve just reminded me of the demise of TransAsia Airways Flight 235 where the right engine feathered itself erroneous, but then the crew misdiagnosed the situation and shut down the left engine. Mentour Pilot made a video on that particular accident.
- Comment on Can someone explain to me how a ventilation fan can suck LESS when on high compared to low? 1 week ago:
I like this answer. The only thing I would add is that when the fan blades are all stalled, it might seem then that drag and energy consumption should reduce, since there’s not much air moving. But in a cruel twist (fan pun intended) of aerodynamics, the useless spinning of stalled fan blades still causes parasitic drag. So not only does the fan not move air, it’s also consuming more energy than spinning a solid disk of the same moment-of-inertia.
When the engine fails for certain single-propeller aircraft, there’s sometimes a mechanism to lock the propeller to make it stop rotating, since it would otherwise “windmill” in the air and waste the previous kinetic energy that’s keeping the plane aloft. Or so I’m told.
- Comment on Is road or rail more expensive? 3 weeks ago:
The other comments correctly mention aspects like managing terrain and the width of railroads vs roadways. What I want to highlight is the development of road building methods at around the same time that metal-on-metal rail developed.
The 1800s were a wild time. Some clever folks figured out that they could put a contemporary steam engine – invented early 1700s; used only for stationary uses in lieu of water power – onto a wagonway. Wagonways are basically wooden or metal guides/flanges so that a horse-drawn wagon could be pulled along and stay perfectly centered on the path.
Up until this point in history, the construction of graded, flattened surfaces for moving goods didn’t change very much compared to what the Romans were doing with their roads. That is, a road had to be dug down and some soil removed, then backfilled with coarse material (usually large stones), and then a layer of smaller stones to try to approximate a smooth surface. The innovations the Roman introduced included a keen eye for drainage – freeze/thaw cycles destroy roads – and surveying methods (also to build things like aqueducts and canals).
But even the best built roads were still prone to rutting, where each passing wagon slowly wears a groove into the road. Wooden wagons wider or narrower than the groove would suffer poor performance or outright break down. The wagonways sought to solve that issue by: 1) forcing all wagons to fit within the fixed guides on the sides, and 2) concentrate the grooves to exactly within the guides. The modern steel-on-steel railway takes this idea to its logical end.
An adhesive railroad seeks to be: all-weather, heavy duty, and efficient. Like Roman roads before it, all railways (except maybe on-street tramways) need to excavate the soil and build it up, usually being higher and wider than the rest of the land. This sturdy base also provides a strong foundation to support heavy loads, preventing the steel rails from sinking or “rutting”. And finally, putting the wheel atop the rail makes for low-friction operation. Early wooden plateways sort-of did this, but they didn’t manage curves like how modern rails do.
All the while, instead of trying to support heavy wagons, another clever person sought to reinvent road building outright, postulating that if a surface could just spread out the load from light/medium traffic, then the soil beneath could be used as-is, saving a lot of earthworks. A gravel surface would meet this criteria, but gravel is not all-weather and can develop rutting. The key innovation was the use of binder (basically glue) to hold the surface together, such as tar. This sealing process meant the surface wouldn’t shift underneath traffic. This neatly avoided the issue of dust, made the surface water impermeable, and reduced road maintenance. So famous is this surfacing process that the inventor’s name can still be found in the surface for airport runways, despite runways always being excavated down to a significant depth.
So on one hand, rail technology developed to avoid all the pitfalls of 1700s roads. On the other hand, road surfacing developed to allow light/medium traffic roads to be economically paved for all-weather conditions. Both developments led to increased speed and efficiency in their domain, and networks of both would be built out.
Rail networks made it possible to develop the “streetcar suburbs” around major historical cities in the late 1800s. But on the same token, cheap road surfacing made it possible to build 1950s American suburbs, with wide, pedestrian-hostile streets sprawling in serpentine patterns. The fact that sealed roads are water impermeable has also substantially contributed to water pollution, due to increased rain runoff rather than absorbing into the underlying soil.

I’m personally very cautious about damage to/around batteries, due to !spicypillows@lemmy.world . At the very least, a photo might help depict the scale of the dent.
- Comment on Why is daisychaining multiple extension cords considered unsafe, even if only done to the length of a standard cable? 3 weeks ago:
I once read a theory on an electricians forum about how the USA electrical code’s mandated maximum distance between adjacent outlets on a wall, coupled with the typical bedroom layout, as well as home builders trying to be as cheap as possible, led to only a single outlet being placed directly in the middle of the longest wall. This is also the most logical position for a bed, so the theory is that the bed pressing against the outlet over time was a contributing factor to electrical-related house fires.
I cannot find where I read that originally, and certainly the granularity of nationally-reported fire data is not sufficient to prove that theory. And while the electrical code’s distance requirements haven’t changed, more homes will now put enough outlets so the only one isn’t behind the bed.
- Comment on Why is daisychaining multiple extension cords considered unsafe, even if only done to the length of a standard cable? 3 weeks ago:
I’m not trying to be ignorant, I’m just curious.
I think you’re in the right community! Don’t let anyone tell you to shy away from asking curious questions. (well, unless the question is also bigoted, illegal, baiting, sealioning, or otherwise disingenuous)
I’m not an electrician in any jurisdiction, but one answer for why two 2-meter (~6 ft) extension cords in series is inadvisable compared to a single 4 meter cord is that it’s not an apples-to-apples comparison. Longer cords necessarily have to be built differently than shorter cords, not only because of electrical codes (eg the NEC in USA) or product safety specs (eg UL, CSA) but also being well-designed for their expected use. There’s also the human aspect, which all good designs must account for as well.
Here in the USA, common extension cord lengths are ~2 m (6 ft), ~7.5 m (25 ft), ~15 m (50 ft), and ~30 m (100 ft). Of those cords, the common wire gauge used might be 18 AWG (~1 mm^2), 14 AWG (~2 mm^2), 16 AWG (~1.5 mm^2), and 12 AWG (~3.5 mm^2). I’ve intentionally rounded the metric units so they’re more analogous to common wire gauges outside the USA. Finally, the insulation used can be anything from “thin, indoor only” to “heavy, abrasion and sunlight resistant”. And while the USA technically has a boat-load of AC connectors, the grand majority will use the standard 2-pin or 3-pin 120v connector, formally known as NEMA 1-15 and NEMA 5-15 respectively. What this means is that chaining extension cords is both possible and somewhat common. The problem is one of mismatched designs.
From a cursory search on the website of a major USA home improvement store, the smallest wire gauge used for a 100 ft cable is 16 AWG. The largest is 10 AWG (nb: smaller numbers mean bigger wire). That thinner cable is marketed for outdoor use. The thicker cable indicates its use “indoor/outdoor” and for heavy-duty applications. It is also branded with a major power-tool company, which would be appropriate as power tools often draw high current.
Whereas looking at 6 ft extension cords, most are 16 AWG but a few were 18 AWG (thinner than 16) or 14 AWG (thicker). But I could not find any thicker cables than that, certainly nothing that uses 10 AWG (~6 mm^2). The “heavy duty” cables of this length also used only 16 AWG wire.
Because electrical resistance is additive in series, and because Ohm’s Law governs the voltage lost at the end of a cord, the use of insufficiently large conductors can cause voltage issues for high-current appliances. Appliances for USA-spec generally require 120 Volts +/- 10%, with utilities aiming to provide 120 Volts +/- 5% from the outlets. This means a “sufficient” power cord should not have a voltage drop of more than 6 volts, give or take. Of course, a high-current appliance will also cause a larger voltage drop than a low-current device, so we only consider the former case.
For a machine that draws 12 Amps attached to a 100 ft extension cord made of 18 AWG wire, the voltage drop would be 15 volts. This is bad for the machine, which now sees a lower voltage than expected. Had the cord been made of 12 AWG wire, the drop is an acceptable 3 volts.
So if you’re operating construction tools, it would be a terrible idea to use three random 6-ft cables, and you should instead use a single 25-ft cable. Even though it’s longer than you need, the fact is that most 25 ft cables use thicker conductors, which reduces the voltage drop overall.
But there’s also that peaky human factor. Sure, there would also be more connectors which could come loose, but the really pressing issue with daisy chained cords is when people do that indoors, because they only have light-duty 6 ft cables handy. And for that Christmas tree, they need to use attach three cables together to go beneath the hallway rug.
This is essentially the worst-case scenario: using thin conductor cords, with thin insulation, underneath very flammable household surfaces, which are also trodden upon by foot traffic. Every step on that cord weakens the insulation and fatigues the conductors. Over time, the conductor becomes thinner where it’s being fatigued, and this increases the voltage drop. An unfortunate result of a voltage drop is that it generates heat. For a cable which is uniformly thin, this heat is spread over the whole length. But for localized conductor damage, the heat is pin-point… directly under a flammable rug.
In the USA, some 3300 house fires started from an extension cord. Because these cords are not within the walls, they are usually beyond the control of often-strict building/electrical codes, something that’s been critiqued by a prominent YouTuber. The US CPSC even goes so far as to create memes to promote their messaging that space heaters – a common, high-current appliance – should not be used with extension cords or strips.
Of course, from an electrical perspective, even a ten-long chain of dinky extension cords would have no problem powering just a single LED night light. But it’s reasonable to ask: 1) is this just asking to be struck down by fate, 2) are there better alternatives like thicker/longer cords, and 3) why isn’t there an outlet where you need it?
(There’s also a scenario where too long or thin of an extension cord can cause a circuit breaker to fail to trip during a short circuit, but it’s fairly esoteric and this post is quite long now)
In short, the blanket recommendation to avoid daisy-chaining cords is to avoid the nasty and sometimes fatal results when that can go wrong, even with it might not always play out that way. There’s almost always something safer than can be done than daisy chaining.
- Comment on How do people end up winning lawsuits against companies due to a missing label or sign? 4 weeks ago:
IANAL, and lawsuits almost always end up being very fact-intensive, which means that the specifics of the case often make the difference. So it’ll depend. But broadly speaking, if there isn’t a specific law – eg ADA – that specifically assigns liability, then the most typical claim someone would try to make is a theory of negligence. That is, failure of the laundromat to behave with a reasonable degree of care.
In the absence of signage or disclaimers or waivers (like in some amusement park rides), the jury will have to assess whether this laundromat’s environment suggested some heightened sense of security (eg security cameras, even fake ones) or that management implied or leaned into marketing that made it sound like clothes wouldn’t be stolen there. But a typical coin-op laundromat has people going in and out at all times of day, so it’s not reasonable to think it’s akin to Fort Knox, even without a sign indicating that management disclaims liability for clothes theft.
As for posting that sign, it won’t change the general lack of liability on the laundromat in a case where someone snatches clothing. But the equation is different if, say, a patron asked a staff member to watch their laundry for 5 minutes as they make a phone call, and that staff member agreed but then went out for a smoke, resulting in an opportunistic thief stealing the $80 bras from the dryer. Here, the laundromat would carry liability, because although they don’t normally watch the clothes, they agreed to do it this once and did it so badly that the clothes were stolen. That’s negligence, despite the sign.
That said, posting a warning sign is generally encouraged, since a core principle of liability is that avoidance of harms is always going to be preferable than litigating after they’ve already happened. So if the sign causes patrons to stay near their clothes in the machine, then some amount of theft has been outright avoided. For this reason, courts seldom will punish a business for having an overzealous sign, unless the sign itself is materially false or the sign itself causes a hazard (eg a loose “Gusty Winds” highway warning sign that falls over in a light breeze, injuring a middle school student).
But to muddy the waters some more, another core principle of liability is that it should fall upon the person whose behavior if changed will prevent future harms. For stolen clothes, it’s quite clear that the thief should be liable for the value of the stolen bras. If a court instead holds the laundromat liable, then that creates a perverse incentive where rather than spending money on more/better washers, the laundromat must spend that money on cameras and private security. All for something which would be more cheaply solved by just watching the laundry, or perhaps installing hasps on the machines so patrons can bring their own locks.
On the flip side, denying liability means the patron has lost the value of their clothes. Perhaps they now have to spend more on “clothes insurance”, which only serves to benefit an insurance company rather than affording more bras. Adjudicating liability – in any legal system – is a thankless job and there are never perfect answers. Life is messy, and even the best civil tribunals struggle to make sense in all of the turbulent circumstances.
TL;DR: it depends
- Comment on How do people end up winning lawsuits against companies due to a missing label or sign? 4 weeks ago:
There is truth in this, but it needs a little bit more context. If a civil lawsuit – eg personal injury claim – goes to trial and either party requests a jury, then yes, the jury is mostly unrestrained in what sort of damages (or none at all) they find. But they don’t have absolute authority.
The caveat is that some jurisdictions have hard caps on the type of damages. Texas limits punitive damages (meant as punishment to ward off copycats from causing the same harms) to 2x the economic damages (loss of money or value; excludes emotional suffering) plus $750k. This was raised as an issue in the lawsuit brought in Texas against Alex Jones where the jury awarded approximately $50 million, although the judge did not determine that the Texas cap would apply, and so it didn’t. Jones could have appealed that decision, but I couldn’t find news articles suggesting he did.
There’s also a court’s inherent duty to deliver due process, which would allow a judge to cut down a jury award which is so outlandish that it is not supported by the evidence. This is similar to throwing out a criminal guilty verdict when no shred of evidence supported guilt. The opposite is rare, as a judge usually doesn’t increase a jury award; judges might add sanctions instead though.
The odd quirk is that the fickleness of juries – both criminal or civil – is often used to broker a settlement or plea deal. When Dominion Voting Systems sued Fox News, their suit requested $1.4 billion in compensation. But a jury could have found more damages than that. But it could also have been much lower. To avoid that gamble, the parties agreed to settle for $787.5 million. A settlement cannot be appealed and permanently terminates the lawsuit, which provides some peace to all parties. As for the merits of criminal plea deals, the pros and cons are better described here: www.ojp.gov/…/plea-bargaining-necessary-evil
- Comment on How do people end up winning lawsuits against companies due to a missing label or sign? 4 weeks ago:
that a law firm thinks it can make money
This is unfortunately rather common in the USA, specifically the issue of nuisance-value lawsuits: scholarship.law.nd.edu/…/351/
So even without a meritorious lawsuit, a law firm can extract what is essential a ransom, because for a targeted business or individual, they would have to pay their own way for a defense attorney, taking time to go to court, and all sorts of other headaches. It can indeed seem reasonable to just pay a few thousand dollars to the attacking law firm just to make them go away.
Even if one jurisdiction were to implement some of those proposed solutions to nuisance-value lawsuits, there are 50 US States and the federal courts, so pernicious law firms can just go forum shopping.
- Comment on How do people end up winning lawsuits against companies due to a missing label or sign? 4 weeks ago:
You’re going to have to clarify what jurisdiction, since USA law is going to be vastly different than EU law, in the realms of product, medical devices, and public accommodations liability.
But if we did examine the USA, then we can find some generalized rules. For product liability – the responsibility of manufacturers and distributors of a tangible object – strict liability will lay when a product has an inherent defect (meaning it didn’t become defective after the initial sale) and this defect causes some sort of injury. Although this criteria doesn’t depend on the frequency of injuries, if a product is accumulating a body count, that’s usually a good sign that there’s a defect. Causality is also important to establish, as well as any mitigations that may have existed. On this front, a manufacturer might argue that the warnings in the instruction manual specifically advised against diving headlong into a 30 cm deep swimming pool. And although warning consumers to not do something may be somewhat effective at discharging liability, warnings alone do not prevent someone from trying a lawsuit anyway; the popular wisdom that the “pages of warnings” in manuals are written by lawyers is only partly true, since most manufacturer prefer repeat business by customers that are still alive.
Medical product liability is similar, but slightly different because medical products are built for a specific purpose but a doctor can instruct a patient to use it differently, if medically appropriate. If not used as instructed by the manufacturer, the manufacturer is usually off the hook, but the doctor might be liable for medical malpractice. Maybe. Doctor liability in the USA is framed within a “duty of care”, meaning that the doctor takes on a responsibility to act with a reasonable degree of skill and competency. The “standard of care” idea is related, in that it sets the floor for what is reasonable for all doctors. It is, for example, grossly negligent to a drunk doctor to examine a patient. Harms from such negligence can be litigated through a malpractice suit. But this doesn’t mean all harm is actionable. A successful appendectomy that results in blood sepsis is always going to be a possibility, even with the best infection controls in place. If all the staff discharged their duties within their training, then negligence does not attach. Also, malpractice is not something which can be waived, because even if a patient doesn’t sue, a doctor’s medical license can be suspended. Whereas the risks of a surgery can be described in detail to a patient, for informed consent.
Finally, public accommodations law sets the floor for how public and private businesses conduct themselves if they provide goods or services to the general public. Very prominently in this realm is accessibility requirements, which are rules that assure the disabled will not have undue burdens that able-bodied people wouldn’t also face. The Americans with Disabilities Act (ADA) provides for very stiff fines for non-compliance, and because its objective was to set the standard, there is no provision for a “fix it ticket” approach for enforcement. That is to say, the ADA does not allow business owners to wait until a wheelchair user makes a complaint; they must follow the standard from day 1.
No doubt there is abuse of the liability laws – there’s nothing more American than filing “ambitious” lawsuits – and this is just a brief (and uncited, '“from the hip”) summary of possible areas of law that might answer your question. But I hope it gives you an idea of why a warning or sticker or sign might incur liability. Or at the very least, an unexpected lawsuit from left-field.
- Comment on If investing in the S&P 500 is such a surefire way to make money, then why isn't everyone doing it? 4 weeks ago:
To start, I’m assuming you’re talking about low-cost index funds tracking the S&P500. All of the “actively managed” funds tracking an index are, IMO, farces designed to extract money for the fund managers rather than delivering value to the (index fund) share holders. A passively-managed index fund is a fairly boring (and cheap) operation to manage, primarily buying and selling shares to keep the same proportions as the tracked index, be it the popular S&P500, the CRSP Total US Market index, or any other imaginable index. The low-cost appears in the very low expense ratio, some measured in single-digit hundreds of 1 percent (eg 0.04% for VTSAX).
As for whether an index fund tracking American large-cap stocks is a “sure fire” investment, absolutely not. Any investment needs to be viewed in terms of its appropriateness, such as being properly diversified (within one’s abilities) and the timescale must match one’s financial objectives. The conventional adage is that everyone would like to win the lottery, but when pressed for a more specific answer, most would say that they just want to live without worrying about finding an income. That is to say, they’re just looking for “enough”.
Practical financial advice aims to sustainably achieve “enough”, usually framed in terms of retirement but quite frankly, the process works for all sorts of goals, such as saving for higher education for oneself or a child, buying a car, building a marriage dowry, or planning to support aging parents. What’s distinct with these scenarios are: the amount needed, and the time remaining to achieve that amount.
For a mid-20s newly-employed knowledge worker (eg mechanical engineer), they have about 40 years until retirement age. Time is a very valuable asset, because time can overcome short-term problems like economic recessions or high interest rates. Even if a recession strikes just prior to turning 65, the nest egg will have grown with 40 years of dividends prior to the recession taking a small haircut. Alternatively, starting one’s career in a recession means post-recovery investments will bolster the savings.
The large-cap index funds (like S&P500) are high risk, high reward. For someone with a long time horizon and a good savings rate like a young professional, large-cap makes a lot of sense. But this is wholly inappropriate for a retired octogenarian who just needs to draw a steady income to pay their living expenses. After all, having already gotten so far in life, the meaning of “enough” changed from “high growth of nest egg” to “drawing down the nest”. So this retired person would probably have gradually swapped out their index funds for things like bonds, which pay less in dividends but are steady even through recessions and bad times.
For a longer discussion about investing according to one’s definition of “enough”, I would recommend reading some pages from the Bogleheads community, like this one: bogleheads.org/…/Bogleheads®_investment_philosoph…
- Comment on It's 54 degrees Fahrenheit (12 Celsius), raining moderately hard, the rain is cold, and there's a guy blowing around wet leaves with a leaf blower. What the hell is the obsession with leaf blowers? 5 weeks ago:
As it happens, it’s about 10 C (50 F) near me, and I did actually think about using my leaf blower for a very specific purpose in the rain: blowing the leaves clear of the gutters.
I saw outside my window that the autumn leaves formed a dam in the gutter, impounding an amount of water which started diverting onto the asphalt and the sidewalk. From what little I know about road construction, water intrusion is the greater enemy so I didn’t want to let the small pond sit there.
In the end, I just picked the leaves up by hand to remove the obstruction. But if I had a lot more gutter, leaf blower would be the first tool to come to mind.
- Comment on If a contestant on Jeopardy! gave the correct response "Alexandre Dumas" but pronounced the surname as "dumb ass", would the response be accepted? 5 weeks ago:
I don’t have much to add about the pronunciation question, but every time that Alexandre Dumas is mentioned, I feel compelled to recommend The Count of Monte Cristo, a work which I would describe as the mid-1800s rough equivalent to a shonen manga. The novel starts in 1810s southern France, just after the Napoleonic era, detailing the luck, misfortune, and events that befall Edmond Dantes, a young and intelligent sailor of modest means.
Admittedly, the unabridged book is quite a long read, with some print editions exceeding 1200 pages. The 117 chapters may be intimidating, but IMO it’s a worthwhile read. It’s also available in the public domain in the USA, so Project Gutenberg has an eBook of it from the 1888 English translation, retaining much of the “antique” translations, for added intrigue.
- Comment on I am about to board a flight. What sequence of events would occur if (by chance) for no apparent reason a window got completely smashed out? 5 weeks ago:
I’m only a passive yet very interested observer of aviation but am also a fairly avid cyclist. I think the equivalent analog for bikes is that it’s much easier to track a straight line when doing 50 kph than at 5 kph. Just like airspeed is needed for rudder surfaces to work, cyclists need speed to maintain horizontal balance and manoruverability.
- Comment on I am about to board a flight. What sequence of events would occur if (by chance) for no apparent reason a window got completely smashed out? 5 weeks ago:
I’m assuming your question pertains to a window failure while still on the airport grounds prior to takeoff. If instead you meant a window failure while airborne, I would suggest this Mentour Pilot video about Southwest Flight 1380 where an engine defect threw shrapnel at one of the cabin windows, smashing it open with disastrous effects.
Supposing the window failed prior to opening the jet bridge to allow passengers to board, it probably would have been noticed by the flight crew – ie the pilots, cabin staff – while doing their preflight preparations and checks, or by the ground crew, while loading baggage or food/supplies. Once notified, the boarding process would be delayed as the pilots assess whether the flight can continue – definitely not – and then the captain would use their authority to reject the aircraft for that flight, calling in the maintenance team and the airline so they can take the next steps. Practically speaking, this flight will be either heavily delayed or outright cancelled.
If instead the window failed after closing the doors and the aircraft has started taxiing to the runway, then there are some complications. With everyone seated for taxiing, passengers are not supposed to start walking around to notify the cabin crew. But the cabin crew may already be walking the aisles to check for stowed trays, seatbelts for takeoff, baggage obstructions, etc. So if they see a smashed window, that’s an obvious sign that the cabin is not secured for takeoff. At the end of the cabin checks, the cabin crew would normally telephone the pilots to convey a secure cabin. Here, they would explain the situation and the pilots would contact ground control to return back to the terminal.
But supposing the window broke after the cabin was declared secure, and the aircraft is about to line up onto the runway. In this case, everyone including the cabin crew are sat down, so a passenger who sees the window can’t really get the cabin crew’s attention by pressing the overhead button. Barring some sort of additional malfunction that the pilots could notice – like a major engine malfunction – this aircraft might actually take off.
When taxiing, the pilots have a number of things to do, and so the “sterile cockpit” rule means that no non-operational chitchat is allowed, to allow them to focus. Mentour Pilot has other videos on what happens when the rule is violated. Likewise, the cabin crew are trained to not disturb the pilots unless something absolutely flight endangering is happening, at least for the first few thousand feet of takeoff climb.
The theory is as follows: if an aircraft is on the ground and stationary, it is safe. If the aircraft is at cruising altitude and cruising speed, it is safe. But if it’s at low altitude (<1000 ft; 330 m), then it’s very easy for the flight to go sour. Hence, once an aircraft has reached a certain point in taxiing, it will basically want to take off. And we still have the problem that the pilots don’t even know the window broke.
So the aircraft rolls down the runway and takes off. Crisis? Not really. The plane will climb quickly up to some 3000-5000 ft, at which point the plane is configured for a steady climb to cruise. This is when the pressurization system would engage, since cabins need to keep the pressure to a breathable level. Although the system may also have noticed that the cabin pressure stayed the same as the outside air pressure for the entire climb. That’s a clear sign of a cabin air leak, and the system would indicate to the pilots of a pressurization failure.
This is the first indicator for the pilots, although at this stage in the flight, the cabin crew may also phone the pilots since they start walking around earlier than 10,000 ft altitude. A pressurization failure or broken window means the pilots must halt their climb and remain below 10,000 ft, which is the upper limit for human breathing without supplemental oxygen. The pilots would radio to ATC and request a return to the airport, or another nearby airport if need be. A pan-pan or mayday could be declared, depending on the captain’s assessment of the situation, or to obtain priority over any other aircraft wanting to land.
The last scenario before the Flight 1380 scenario is if the window broke just as the aircraft was passing 10,000 ft altitude, so there was no earlier indication of a cabin leak. In this case, there will indeed be a cabin depressurization, although it won’t be as severe as at cruise altitude. Some aircraft will automatically drop the oxygen masks, and the pilots will don their own masks, now cognizant that a full-blown emergency is underway. This is handled the same way: bring the aircraft down to a breathable altitude and call ATC. The oxygen masks are good for some 20 minutes, which is well more than enough time to return to a lower altitude and make a plan.
TL;DR: the entirety of Mentour Pilot’s YouTube back catalog truly sheds light on how the aviation industry keeps people safe. I highly recommend.
- Comment on Since removed comments can still be read in the modlogs, isn't removing comments useless? 5 weeks ago:
I’m going to address the question in two halves: what is the point of moderation overall, and what legal consequences exist when moderation (or the lack thereof) go awry?
Mike Masnick of TechDirt has written extensively about why moderation must exist for any large-scale, publicly-available web platform, most notably in this article describing the “moderation learning curve”. That article goes through the “evolution” of a supposed “anything goes!” platform that is compelled – by economic forces, public sentiment, existing laws on CSAM, and more – to do moderation. But even the very act of drawing a line in the sand will always be objectionable to someone somewhere, so it’ll always be a thankless job. Even harder is applying a moderation policy consistently.
But we’re getting a bit too philosophical. Why does a platform – from the largest like Facebook to the smallest Lemmy community of four people – do moderation? A few answers:
- If stated community’s rules are regularly violated, those rules cease to have any authority
- If users are not comfortable in a community, they will leave
- If posters do not feel welcome to post, they will leave
- If mods don’t take action on illegal or unpermitted content, they themselves might be removed/replaced by the server owner
- If the server owner knowingly hosts illegal content or fails to adequate perform minimal screening, their ISP/CDN might drop them as a customer
- If other platforms or venues exist for removed content, then it’s not really a negative impact on the "marketplace of ideas"
- If moderation removes content that the user-base liked, then those users are free to follow the content to another platform; there are no hostages taken on Lemmy, and radicalization can still form online just like it can form at the local library by reading Wage Labour And Capital
For the legal aspect, I can only write from a USA perspective; IANAL. Broadly speaking, Section 230 of the Communications Decency Act provides that: 1) a web provider that hosts content authored/submitted by another person will not share in any civil liability incurred by that person, and 2) no web provider will have civil liability for their moderation decisions made in good faith. Together, this means only the original author of some defamatory post can be sued for that defamation, not the platform. And if the platform removes that defamatory post as part of moderation, the original author does not have a right to sue the platform. In shorr, this provides a lot of protection from civil lawsuits if they do moderate, or if they don’t. But if they don’t, the practical issues from earlier will still arise.
But federal law imposes additional obligations for web providers, with civil or criminal penalties if not properly dealt with, for specific types of content. That is, content that enables sex trafficking, or CSAM. Sex trafficking was specifically carved out from Section 230, and CSAM is a possession crime: its mere presence on a hard disk, however acquired, is unlawful.
Putting this all together, a Lemmy mod that deletes a post is performing moderation. They might do so because the post is irrelevant to the users or violates some rule. Whether the mods leave the post up or take it down, the broad civil immunity of Section 230 means the platform can’t be sued for it, nor can the post’s author sue the platform. So the post remaining in the modlog does not pose any new legal vulnerability. Rather, removing the post proves the value of having mods, so that other users don’t even have to see it. Post removal intentionally curtails “freedom of reach”.
The exception to leaving content in the modlog is if it might be CSAM or otherwise illegal content. In that case, the mods can scrub it from even the modlog and anywhere on the platform. This complexity is why anyone hosting a Fediverse instance hosting other people’s content is advised to follow guides on how to do so. Here’s another one.
TL;DR: the mods have a job to do, everyone wants a healthy community, and the law has only a small – but exceedingly important – handful of obligations.
- Comment on Why can't someone create a public alternative to health insurance in the USA? 5 weeks ago:
Thanks for pointing this out. I offered State Farm as an example because they’re the largest auto insurer in the USA, but with just that example, I can see why someone might get the impression that mutual == bad. I happen to be a happy State Farm customer, but I’m aware this isn’t universal.
I’ve added Amica and Liberty Mutual USA as additional examples to address this.
- Comment on Why can't someone create a public alternative to health insurance in the USA? 5 weeks ago:
Health insurance at its core is very simple. … But in the USA…
I wrote this lengthy post a few months ago about why the American health insurance system is not efficient in comparison to the auto insurance system:
So to answer your question directly, the costs for healthcare in the USA continue to spiral so far out of control that it causes distortions in the health insurance market, to everyone’s detriment. Specific issues such as open-enrollment periods, employer subsidies, and incomprehensible coverage levels all stem from – and are attempts to reduce – costs.
The auto industry has examples of “mutual insurance” companies, where the company at-large is partly or wholly owned by the policyholders (eg State Farm). And that mostly achieves the objectives you’ve described for a non-profit automobile insurance pool. Sadly, this just doesn’t work in the USA, for the aforementioned bottom-line reason.
Hospitals and doctors go through intense negotiations with insurers to come to an agreement on reimbursement rates, but the reality is that neither has sufficient actuarial data to price based on what can be borne by the market. So they just pass their costs on, whatever those may be, and insurers either accept it into their calculations, or drop the provider.
When prices for service are opaque, how can any insurance company – even the most benevolent – properly price their policies? To stay in business would require always overestimating than underestimating. The extra revenue becomes either profit or float. But this float can’t even be beneficially used or paid out, in case the next quarter has more expensive claims to pay. Which brings us full circle to opaque pricing.
In this environment, the only remaining prudent thing for a benevolent health insurance company to do is to hold huge reserves. But that is not competitive against profit-seeking insurance companies that can undercut the benevolent company, who had tied one hand behind their back. Benevolent companies rarely survive.
- Comment on Can the public expect to get to see Luigi Mangione's 3 page manifesto in its entirety in a reasonable timeframe? 1 month ago:
There are a number of rights which are curtailed when in custody – whether pre-trial or as part of a sentence – but even under the appalling incarceration standards in the USA, the right to free speech is not something which is substantially limited while in custody, barring some very particular circumstances.
A defendant in jail awaiting trial has not, by definition, been convicted of any wrongdoing. So for pre-trial detention – where the purpose is to assure that the defendant won’t skip court – the only cognizance reason to curtail the defendant’s speech (either by mail, phone, or in-person) would be for jailhouse security reasons, as noted by various court rulings. The ACLU has litigated cases where prisons – ie post-conviction detention – violation the prisoners’ rights, so no doubt that pre-trial defendants in a jail would preserve more rights.
An example where free speech continued even while serving a sentence is when the Menendez Brothers gave a phone interview from a California prison, as part of a new documentary on the 1989 murders they were convicted of, now under scrutiny.
On the flip side, there are times when a defendant must have some speech curtailed prior to trial, even if they’re not in jail. Sam Bankman-Fried (SBF) comes to mind, who was ordered pre-trial to not communicate with employees of his exchange (unless all lawyers are present) as the judge agreed with prosecutors that he could try to manipulate them into lying to the feds.
What would be outrageous in that case was if the order was more sweeping, such as being restricted from talking about his own case, for which he has a First Amendment right to do so.
Appropriately, the First Amendment rights must be jealously guarded, even for people we might not agree with, precisely because it also protects people we do agree with.
- Comment on Why dont hackers just do white-cap hacking and figure out loopholes in valuable companies' stuff and use their fiduciary duty as a legal basis to compel patronage of their services? 1 month ago:
and use their fiduciary duty as a legal basis to compel patronage of their services
Do you mean a hacker should find a company’s tech vulnerability and then either: a) inform the company that a vulnerability exists and they should pay $XYZ to learn what it is, or b) inform the company that a vulnerability is known and it will be disclosed unless $XYZ is paid, or c) simply inform the company of the vulnerability and hope that they’ll pay the hacker to consult on how to fix it?
Scenario A is generally permissible, if such a vulnerability does exist. Things like NDAs and contracts can be agreed before the hacker describes the vulnerability, to legally protect the company in case the hacker was bluffing. That said, even without contracts, falsely claiming that a vulnerability exists or that the hacker knows what it is would be fraud in most jurisdictions.
Scenario B is blackmail, and is illegal. [shocked Pikachu face]
Scenario C is possible, although there’s no guarantee that the company is looking for consulting. Although if the hacker’s speciality is both how to identify and patch such specific vulnerabilities, this may be more likely.
That said, taking a step back, are you sure you meant to reference the fiduciary duty that corporate directors owe to their shareholders? This is not the same as the business judgement rule, where directors must act with reasonable prudence in the company’s best interest. The latter rule exists because there may be multiple tactics to fully honor the fiduciary duty, and it would be inequitable to allow suits against directors just because they decided to achieve the objective in different ways.
Neither the fiduciary duty nor the business judgement rule penalize a director just because a business challenge arises, such as a data breach. Rather, the fiduciary duty is violated when a director hides info from the shareholders, or does not follow explicit instructions from the shareholders. And the business judgment rule will not protect a director that is working in bad faith or taking unreasonable risks with the company’s assets.
Declining to hire a hacker as a consultant is a reasonable course of action. It would be a strange – but not impossible – instruction for the shareholders to order the management to “never negotiate with terrorists” but absent such a command, there wouldn’t be a violation of the director’s duty of care.
- Comment on Why don’t more people start profit-sharing companies or co-ops? 1 month ago:
The short answer is that starting or incorporating is the easy part, and the hard part is guiding the seedling of an idea through a array of hazards, any of which can quickly sink the plan.
For clarity, I will use the term “organization” to broadly refer to a group of people and resources dedicated toward a goal, which includes what you described as profit-sharing companies and co-ops, as well as the predominant business structures like for-profit corporations (ie INC, LLC) or non-profits charities, plus groups that use those structures in non-conventional ways, like 501©(4) “social welfare organizations” that incorporate for flexibility but constrain their operations to what is within their remit (eg DSA, NRA). Although it might seem that I’m focusing on tax-exemption by referencing the American IRS tax code, this is more a short-hand to refer to organizations voluntarily constraining themselves by their own terms, in contrast to even narrower types of entities which are constrained by law. The latter might include a Limited Liability Partnership, which in California is only granted for a union of lawyers, architects, or accountants.
As for why I’ve expended a whole paragraph to describe the different ways that organizations can form themselves, it’s because the formation often has little to do with the intent of the organization, the current or future size of the endeavor, or whether they’re likely to make it off the ground. Any and every organization enters this world as a small, tender operation, and neatly falls into what the US Small Business Administration (SBA)'s Office of Advocacy would describe to as a “small business”. This includes any prospective co-op or even a one-person venture, and unfortunately the odds are heavily stacked against small businesses.
Since co-ops and profit-sharing companies would play in the same capitalist environment, I think it’s fair to equate these organizations with “small businesses” at large, for the purpose of this analysis. From that SBA document, only two-thirds (67.6%) of new businesses last longer than 2 years, and less than half (48.9%) make it past 5 years. And of the businesses led by minorities – specifically women, veterans, Black, Hispanic, and Asian descendants – their percentages were even lower.
When you think about it, a successful organization requires 1) genuinely visionary leaders, as well as 2) the staff to carry out the objective, plus 3) resources to enable the organization, plus 4) a measure of luck. Much like in a game of Settlers of Catan, it is rare to hold all the requisites at once, let alone at the very start of the game. Whereas conventional stories of capitalist success generally focus on a genius or lucky young upstart that upends the business world through shrewd business acumen – thus providing their organization with the first requisite – I think the co-op and profit-sharing models start with having the second requisite, usually forming the initial group of dedicated employees.
And I don’t disagree that there are lots of community-minded individuals that are able and willing to come together towards a common cause. But the crux of an organization is that it, er, organizes people and resources in an efficient manner for that common pursuit. I am of the opinion that true leaders with the necessary impassioned drive and ability to inspire and rouse their organization’s staff are far and few between. And that’s even before considering their core competencies in addressing organizational crises, their handling of public relations, and their personal and business roles in the socioeconomic environment.
We need only look at the conventional business world to see where corporate leaders absolutely drop the ball and pull the organization downward, be it Boeing’s various CEOs following the MD merger, to convicted fraudster Martin Shkreli of Turing Pharmaceuticals, and more. But while there are a lot of really awful leaders taking their organizations down with them, there must also be run-of-the-mill leaders who do actual leadership, whether for manufacturing, charities, food banks, actual banks or credit unions, and more. The problem then for requisite #1 is a matter of incentive: for those leading successful capitalist organizations with nation-wide scope, what would attract them to help lead a smaller organization to provide daycare and pre-K at the local level? If there is a genuine shortage of qualified leaders, then capitalist incentives would mean they seek out bigger operations to use their skills, not smaller ones.
That, of course, just means that communities need to be producing more people that are qualified to be leaders (requisite #1), in addition to forming the communities that will become the staff of those organizations (requisite #2). I will not dwell on the third and fourth requisites, as it’s fairly obvious that even with good leaders and good people, if the means of production aren’t present, there’s not much to be done.
As a closing food-for-thought, much of what I’ve discussed above is very American-centric, as our notions of organization are both democratic yet republican in nature. That is, we want to enable the masses to participate (requisite #2), but we also expect leadership to be singular individuals (requisite #1). This does work, and certainly dates back the eras of kingdoms and empires – have you thought of the Roman Empire today? – but it may be worth exploring leadership that is also democratized.
Switzerland comes to mind, as their Federal Council – the closest equivalent to the US President or a company chief executive – is actually seven people, whom all serve as the collective head of state and head of government for the country. Note that this is not equivalent to a company Board of Directors, which is more analogous to the Federal Assembly of Switzerland, which is the parliament with legislative powers to set policy. Furthermore, this is not to be confused with direct democracy, which the Swiss also do, by way of referendums.
It’s possible that rather than needing to develop more skilled leaders, an alternative is to assemble a small, core group of individuals who together have enough skills to competently lead a co-operative organization. This would certainly be more tractable, although I haven’t given enough consideration as to how this would work, and whether there are any existing models to look at. It might or might not mirror the qualities needed from existing, successful co-ops and profit-sharing companies, with REI and WinCo Foods coming to mind.
- Comment on how do you workout when you don't have much time? 1 month ago:
This is a shorter answer than I typically would write, but any sort of exercise program should be atuned to your specific circumstances, since if it’s not practical to execute upon it, then it’s not going to sustainably achieve its objectives.
As for me personally, I wrote my program based on a friend’s five-day-per-week program, which splits the days into: arm day, back/shoulders day, chest day, leg day, and core day. I specifically do not want to be overworking certain muscle groups without adequate rest. Each day takes no more than 60-70 minutes, including warm ups.
Might I suggest posing in c/gym or c/homegym for advice on how to tune your current program; there shouldn’t be a need for a full rip-and-replace.
- Comment on Can a disk image with multiple partitions be shrunk in a reasonably easy way? 1 month ago:
I’m sure there’s probably some sort of mdadm invocation to shrink an existing RAID1 mirror pair, but in the absence of that, one option is to create the mirror pair you want on your 2.5" SSDs, and then shrink-and-clone the filesystem from the NVMe mirror to the 2.5" SSDs, using something like Gparted.
In that way, you end up with the mdadm pair that you wanted, and the filesystem is correctly sized.
- Comment on why is the mexican-american war considered "the last war of humanity"?? 1 month ago:
I don’t have a complete answer, but the mechanization of warfare should have a lot to do with it. Things like the semi-automatic pistol – they would have called it an “automatic” pistol during that era – the modern hand grenade, the airplane for reconnaissance (although lighter-than-air balloons might have been used? IDK), and other weapons wouldn’t have really appeared for the Mexican-American War (1846-1848).
Or did you mean the Spanish-American War (1898)? I think the same logic still stands, especially since train networks would have been more fully developed by the turn of the century.

- Comment on Can someone explain the framework of the current British... idk is empire the correct term? 1 month ago:
For other examples of countries-in-countries, we can look to Switzerland, Germany, and the USA. A casual observation of all three are that their first-level political subdivision is known as a “state” and not “province” or “territory”.
Swiss history – which I admit I’m not that clear on – shows that the modern sovereign state formed as a loose confederation of smaller kingdoms unifying together. Indeed, the foundational document of the modern Swiss Confederation in 1848 directly drew inspiration from the USA Constitution of 1789. However, they made some modifications, such as having a 7-person Federal Council, which together fulfill the role akin to the American President. That is, the role of Head of State and also Head of Government (aka a Prime Minister). This style of executive governance hews more closely to the rich Swiss traditional of direct democracy, rather than that of a purely representative republic.
Germany, specifically the successor state of West Germany post-WW2, and then the unified state of Germany post reunification, is a federal republic. A republic to restore the functions of the earlier Weimar Republic, and a federation of states because of USA influence in drafting the Basic Law – Germany’s Constitution – following WW2. But unlike the USA federal system, the German system would mimic the parliamentary system of Westminster, being that of the United Kingdom. So while governmental power is distributed amongst the several states and the federation, the governance would be through indirect election of the Prime Minister. The idea is that by dividing power this way, no mustached fellow with fascist ideas could take control of the organs of power again.
Finally, examining the oldest continually-operating example, the USA currently is composed of a strong federal entity and 50 US States that wield all remaining power not reserved to the federal government. But initially, this is not what the American Founding Fathers had in mind at all. The late 1700s envisioned the original 13 colonies of the early United States of America to be independent countries that confederated for common causes, like defense and foreign policy. The precursor to the US Constitution – the Articles of Confederation (1777) – tried this, but problems quickly arose because each State had their own currency, debt levels, legal systems, and often undermined each other to advance their own position, such as favoring in-state citizens in lawsuits filed by out-of-state citizens. This made trade difficult and the federal government had little power to do anything about this.
Even with the revised US Constitution document, the whole weak federal government thing continued until the 1860s during the American Civil War, with the aftermath being a federal government that fully asserted its powers under the US Constitution. Any notion of US States being country-like would have fully evaporated by then, especially during Reconstruction when the Guarantee Clause was used to install military governance in the defeated southern states until reintegration into the Union. Such a thing would be impossible for a modern country/sovereign state.
To that end, the modern US State is still a sovereign entity, in that certain things are wholly within their domain and not of the federal government’s. But US States are still beholden to the US Constitution, use the same money as the Union, and must honor interstate commerce and contracts from in- and out-of-state, as well as judicial rulings from the federal court system. But this dual sovereignty system post 1860s continues to evolve, with some states encroaching on federal authority, such as with border control.
Aspects of these three example countries find their way into most of the modern governments of Western countries, so hopefully this was a useful explainer.
- Comment on Can someone explain the framework of the current British... idk is empire the correct term? 1 month ago:
I’ll take a cursory stab, but other references exist for the minutiae of how these things came to be.
Britain == United Kingdom Great Britain == an island wholly within the UK United Kingdom: a sovereign state (eg USA, Germany) composed of the constituent countries of England, Scotland, Wales, and Northern Ireland, plus a few overseas territories. Briton: a British citizen, or someone tracing their ancestry to the UK constituent countries
The short answer for why a country (UK) can have countries (eg Scotland) in it is because the notion of sovereign states (the modern definition of countries) only came into existence in the 18th century or so.
Canada, formerly the Dominion of Canada, formed from the British North American holdings plus the French parts that the British bought (ie Quebec). Granted self governance in the 1860s, independence in the 1930s, and finally full “patriation” in the 1980s to remove all vestiges of the UK from Canadian laws. However, the independent Monarchy of Canada remains, and just happens to coincidentally follow the exact same selection rules as the British Monarch. So the King of Canada will be the same person as the King of the United Kingdom, even though the Government of Canada is no longer controlled by the Government of the United Kingdom. In both sovereign states, the King is a figurehead from where authority and governmental legitimacy emanates, and the current King of Canada continues the tradition since Queen Elizabeth II that the Monarch’s appointed Governor-General of Canada shall represent the Monarch in all Canadian matters, meaning the Monarch will not directly involve themselves.
Why still keep the Monarchy of Canada? The voters haven’t chosen otherwise, to pursue a republic or any other form of government. The same applies in Australia, although it’s slightly more complicated as each Australian State derives their state-level authority from the Australian Monarch, whereas Canadian provinces exist as a part of the singular Canadian confederation. Nevertheless, with the Monarch delegating power within each of his “realms” to the respective Governor-General, becoming a republic is a matter of passing bills in the parliamentary system. Barbados did exactly this in 2022, replacing Queen Elizabeth II with a republic.
The British Isles includes both the Island of Great Britain (where Wales, Scotland, and England are) plus the Island of Ireland (where the Republic of Ireland, and Northern Ireland are), and a few smaller islands. So yes, every part of Great Britain is a part of the UK, but the UK also includes the Isle of Mann and the upper part of the Island of Ireland.
In all circumstances, “Ireland” means the Republic of Ireland; it’s almost never called “southern Ireland”. The whole history of British colonialism in Ireland is long, sordid, and full of misery, culminating with The Troubles of the 1960s and still causing concern post-Brexit due to the EU border basically dividing the Island of Ireland.
- Comment on What's wrong with Bluesky App? 2 months ago:
To start, let’s verify that Bluesky the app is indeed open-source. Yep, it is. But that’s not the same as having all the machinery be open-source, where anyone could spin up their own, compatible service; maybe named ExampleSky. To be compatible, ExampleSky would need to use the same backend interface – aka protocol – as Bluesky, which is known as ATProto. The equivalent (and older) protocol behind Mastodon and Lemmy is ActivityPub.
ATProto is ostensibly open-source, but some argue that it’s more akin to “source available” because only the Bluesky parent company makes changes or extensions to the protocol. Any alternative implementation would be playing a game of chase, for future versions of the protocol. History shows that this is a real risk.
On the flip side, Mike Masnick – founder of Techdirt, author of the 2019 paper advocating for “protocols, not platforms” that inspired Bluesky, and recently added member of the board of Bluesky – argues that the core ability to create a separate “Bluesky2” is where the strength of the protocol lays. My understanding is that this would act as a hedge to prevent Bluesky1 from becoming so undesirable that forking to Bluesky2 is more agreeable. To me, this is no different than a FOSS project (eg OpenOffice) being so disagreeable that all the devs and users fork the project and leave (eg LibreOffice).
But why a common protocol? As Masnick’s paper argues, and IMO full agreement with what ActivityPub has been aiming towards for years, is that protocols allow for being platform-agnostic. Mastodon uses are keenly aware that if they don’t like their home instance, they can switch. Sure, you’ll have to link to your new location, but it’s identical to changing email providers. In fact, email is one of the few protocol-centric systems in the Internet in continued use. Imagine if somehow Gmail users couldn’t send mail to Outlook users. It’d be awful.
Necessarily, both ActivityPub and ATProto incorporate decentralization in their designs, but in different fashions. ActivityPub can be described as coarse decentralization, as every instance is a standalone island that can choose to – and usually does – federate with other instances. But at the moment, core features like registration, login, or rate limiting, or spam monitoring, are all per-instance. And as it stands, much of those involve a human, meaning that scaling is harder. But the design suggests that instances shouldn’t get too large, so perhaps that’s not too big an issue.
ATProto takes the fine-grained design approach where each feature is modular, and thus can be centralized, farmed out, or outright decentralized. Now, at this moment, that’s a design goal rather than reality, as ATProto has only existed for so many years. I think it’s correct to say for now that Bluesky is potentially decentralizable, in the coarse sense like how Mastodon and Lemmy are.
There are parts of the Bluesky platform – as in, the one the Bluesky organization runs – which definitely have humans involved, like the Trust and Safety team. Though compared to the total dismantlement of the Twitter T&S team and the resulting chaos, it may be refreshing to know that Bluesky has a functional team.
A long term goal for Bluesky is the “farming our” of things like blocklists or algorithms. That is to say, imagine if you wanted to automatically duplicate the block lists that your friend uses, because what she finds objectionable (eg Nazis) probably matches your own sensibilities, then you can. In fact, at this very moment, I’m informed that Bluesky users can subscribe to a List and implement a block against all members of the List. A List need not be just users, but can also include keywords, hashtags, or any other conceivable characteristic. Lists can also be user-curated, curated by crowd sourcing, or algorithmically generated. The latter is the long goal, not entirely implemented yet. Another example of curation is “Started Packs”, a List of specific users grouped by some common interest, eg Lawsky (for lawyers).
So what’s wrong with Bluesky then? It sounds quite nice so far. And I’m poised to agree, but there’s some history to unpack. In very recent news, Bluesky the organization received more venture capital money, which means it’s worth mentioning what their long term business plan is. In a lot of ways, the stated business plan matches what Discord has even doing: higher quality media uploads and customizations to one’s profile. The same statement immediately ruled out any sort of algorithmic upranking or “blue checks”; basically all the ails of modern Twitter. You might choose to take them at their word, or not. Personally, I see it as a race between: 1) ATProto and the Bluesky infra being fully decentralized to allow anyone to spin up ExampleSky, and 2) a potential future enshittification of Bluesky in service of the venture capitalists wanting some ROI.
If scenario 1 happens first, then everyone wins, as bridging between ActivityPub and ATProto would make leaps and bounds, and anyone who wants their own ATProto instance can do so, choosing whether they want to rely on Bluesky for any/all features or none at all. Composability of features is something that ATProto can meaningfully contribute to the protocol space, as it’s a tough nut to crack.
But if scenario 2 happen, then we basically have a Twitter2 cesspool. And users will once again have to jump ship. I don’t personally use Bluesky, being perfectly comfortable in the Fediverse. But I can’t deny that for a non-tech oriented audience, Bluesky is probably what I’d recommend, and to opt-in to bridging with the Fediverse. Supposed episodes of “hyping” don’t really ring true to me, but like I said, I’m not currently an invested user of Bluesky.
What I do want to see is the end result of Masnick’s paper, where the Internet hews closer to its roots where interoperability was the paramount goal, and the walled gardens of yore waste away. If Bluesky and ActivePub both find their place in the future, then IMO, it’ll be no different than IMAP vs POP3.
- Comment on Why do the majority of women still take their partner's last name? 2 months ago:
Pew Research has survey data germane to this question. As it stands, a clear majority (79%) of opposite-sex married women changed their family/last name to their husband’s.
But for never-married women, only a third (33%) said they would change their name to their spouse’s family name. 24% of never-married women were unsure whether they would or wouldn’t change their name upon marriage.
From this data, I would conclude that while the trend of taking the husband’s last name is fairly entrenched right now, the public’s attitude are changing and we might expect the popularity of this to diminish over time. The detailed breakdown by demographic shows that the practice was less common (73%) in the 18-49 age group than in the 50+ age group (85%).
However, some caveats: the survey questions did not inquire into whether the never-married women intended on ever getting married; it simply asked “if you were to get married…”. So if marriage as a form of cohabitation becomes less popular in the future, then the change-your-family-name trend could be in sharper decline than this data would suggest.
Alternatively, the data could reflect differences between married and never-married women. Perhaps never-married women – by virtue of not being married yet – answered “would not change name” because they did not yet know what their future spouse’s name is. No option for “it depends on his name” was offered by the survey.
