What I want is something that amounts to a stateful firewall/allow list on top of PiHole ... if a device is attempting to connect to an ip address which was not resolved by PiHole then it gets blocked ... Similarly if the RDNS for an address resolves to a domain PiHole would block it gets dropped as well.

Far too many apps/IoT/appliances have gotten smart and use DoH (or similar methods of circumventing network control). Despite that they all require routing and can still be forcibly cut off.


Similar story with Portmaster 2s and a wall of modems layed out. The resulting blinking lights acted like a load monitor of sorts as the activity would spread across the wall as customers dialed in after work and signed off at night. Not mention a wall of flashing red lights made a pretty good picture of ‘the internet’ for those just starting out on this adventure in 1997.


The biggest missing piece in these definitions? The tires. Most cars these days come with a very highway biased tire. These tires will fail very quickly in most conditions found on off road trails, especially those that are designated as 4x4 required. Failure can be as innocuous as limited traction or complete such as a flat tire from a puncture. If you are in a situation where a tire is punctured from lack of durability how do you think that space saver spare (or can of fix-a-flat) is going to help you get out?

The second major issue with AWD systems is often the clutch based systems that are engaged to transfer power ‘from the wheels that slip to the wheels that grip’. When used in demanding conditions these systems can overheat and shutdown. This also applies to brake biasing systems as well (brakes applied to spinning wheels to transfer torque to other wheels). It can be especially challenging for brakes as there is generally not sufficient air flow over the brakes to cool them during slower speed off-road travel.


No car with paint you care about should ever be washed in the sun. If you look around some detailer forums for basic car washing instructions staying in the shade and carefully drying your car are very important to avoid water spots, swirl marks, and similar damage. Cars with dark colors are particularly notorious for this type of damage.


> water spots, swirl marks, and similar damage

Water spots and swirl marks from being washed in the sun are not damage. It's just material left around from water drying. The grooves in the paint type of swirl marks are from rubbing the dirt and grit against the paint and nothing to do with the sun.


> No car with paint you care about

The Cybertruck is bare stainless steel with plastic trim, isn't it? So paint damage shouldn't be a concern.


I've owned many cars over 20 years and outside of cosmetic water marks due to evaporation on a hot car, have never heard of paint damage this way.


Ever own any cars with the flat/plain color(without sparkle/glitter)? I'm kind of wondering whether water drops can magnify the sun's ability to fade paint in a detectable way in those types of paints. I don't imagine it could unless the drops were forming in the exact same positions every time.


> No car with paint you care about should ever be washed in the sun.

Are you being serious?

I have never heard of cars being washed in any other way.


>> No car with paint you care about should ever be washed in the sun.

> Are you being serious?

Probably given "If you look around some detailer forums". I've seen the don't wash in the sun part, but it is about getting the "perfect" clean and not damage. The damage prevention parts usually involve reducing the amount of dirt and grit be rubbed against the paint like foam cannons, multiple buckets/clothes/mitts, grates, clay, etc.

> I have never heard of cars being washed in any other way.

I have a feeling you two are looking at it from vastly different perspectives. You seem to have a more utilitarian view of car washing. You know your car is going to receive damage as you use it. Minor scratches and fading that you have to inspect for are the least of your worries. The other person seems to view cars as important status symbols and any "easily" seen imperfection is a blemish.

They cite that the data in the study was from 2011-2015. Cars have changed significantly in that time so it is worth remembering that the common stability and traction control, and safety systems on cars sold today are significantly improved from those when this study was performed.

A performance automobile or sports car can certainly perform at levels that raise risks. That said I would rather be in an automobile that spends most of its time operating far below its capacity with sufficient performance reserve to handle emergency situations despite being significantly handicapped by a less than perfect human driver.


Wait, what?

- Performance cars tend to be bought by people with risky traffic habits. And no, just because somebody thinks of themselves as having the driving skills of a professional racing driver, and have the fanciest wheels they can afford, doesn't mean their driving skills, or more importantly, their appreciation of risk in different traffic situations, match reality.

- Few accidents are caused by lack of performance.


> Cars have changed significantly in that time

Too bad the drivers haven’t. I get the point that the cars are safer for risky driving but risky driving still doesn’t belong on public roads.


From the article: “ Research found speeding or jumping a red light less likely in a Skoda or Hyundai than in brands sold as ‘performance driving’”

Those safety systems are nearly irrelevant in the face of reckless driving. Most people, including those buying performance cars, are not spectacular drivers.


> That said I would rather be in an automobile that spends most of its time operating far below its capacity with sufficient performance reserve to handle emergency situations despite being significantly handicapped by a less than perfect human driver.

What's an example of a modern passenger automobile that DOESN'T spend most of its time operating far below its capacity and/or WITHOUT sufficient performance reserve to handle emergency situations despite being significantly handicapped by a less than perfect human driver?


Try doing a panic stop, or even an emergency lane change, in a Suburban or Tahoe some time.


A panic stop is mostly a question of speed not the cars performance.

This means a speeding Porsche has worse handling than a Tahoe driven reasonably. Which is what this study uncovers, performance cars don’t offset reckless behavior.


That is false. At the same speed, the SUV will have MUCH worse performance.

Porsche 911 Turbo braking distance, 70mph-0: 133ft

For most typical SUVs, that value is 160-well over 200ft. That's multiple car lengths of distance. Easily the difference between rear-ending someone and not.


You obviously didn’t read what I said. “a speeding Porsche has worse handling than a Tahoe driven reasonably

On average the SUV and Porsche will not be driven at the same speeds therefore the actual stopping distances should not be calculated using that assumption.


You obviously made up a bizarre tangent that isn't relevant to the original comment at all.


It’s directly related to the actual research and counters your original statement. Aka when reality disagrees with your intuition, reality wins.

Plenty of BMW etc drivers made panicked stops before dying because they had gotten into a situation where their car and reflexes couldn’t save them from physics. No car can save people from stupid.


This study is really examining the driver’s behavior not the inherent safety of the cars.

The fact such improvements are available on other cars not driven as recklessly means 2023 and 2030 Porsche etc drivers will also be more likely to be involved in an accident. The only only way this changes is if the culture around these brands change or if cars stop allowing people to be in control because as long as someone can decide to drive at 120+ MPH physics dictates inherent risks.


The point isn't that these cars can perform at high levels, it's that the branding encourages people to.

My 2009 Toyota Sienna minivan has more guts to it than I'll ever use (and so it spends most of its time operating far below capacity), but minivan drivers aren't generally known for risky maneuvers and excessive speeds.

Stories like this remind me that in distributed systems time becomes a very imprecise concept at small scales.


What?


Think of it this way: you run a website that displays photos in chronological order. You receive these two photos. Which picture was taken first? How can you tell?


I've looked at user telemetry and the conclusion I've come to is that the only time you can trust is from systems under your control (i.e., submission time).


It's why the US patent system switched from "first to invent" to "first to file" in 2013. The last country to do so.

https://en.wikipedia.org/wiki/First_to_file_and_first_to_inv...


That's not an example of a distributed system, so it doesn't really clear up whatever the GP was trying to say about time in distributed systems at small scales.

But even if it was this is nonsensical. The visual content of a photo is generally not what is used to determine the moment in time when it was captured. There's metadata in the image format that specifies when the photo was taken.

There are pictures taken at almost the same moment in time all the time around the world, and there are many pictures taken of the same place, what's special about the situation here is that both of those things happened, and the subject isn't hyper famous, and it isn't a static object, so the chances of it happening were very low.


The distributed part is the clocks on the cameras across the world. The article discusses the timestamp is included in the exif data embedded in the jpeg file.

The clocks are most likely synchronized based on gps assuming they’re already pulling location data from the satellites, the time is “free”. However, the precision of the clocks is not specified and like any process is subject to error. So at the small timeframes here (sub millisecond), you are potentially within the margin of error. When the error bars of several measurements from distributed parts of your system overlap, how do you determine an ordering between them?


Whoever arrives first? Since they can't arrive at the same time because of sequential processing at the final step. So the guy who implemented the system will be the arbiter of truth.


Got it. Can’t know what time it is exactly if you have 2 clocks.


I’ve used the shaped orange foam 3M ear plugs extensively while riding a motorcycle. The wind noise is extremely bad for you given the duration and surprisingly high decibels.

One interesting thing I have noticed is that these plugs are extremely sensitive to being inserted correctly and despite extensive experience and good technique (which for me involves two hands, one to insert and one to pull the top of my ear for alignment) I still find the need to reinsert plugs on occasion.

Unfortunately the poor fit isn’t obvious until I am on the road at speed when the sound volume is higher than it should be. If this same situation arises in combat I can easily imagine that the higher intensity of noises would cause hearing damage far sooner and in addition it seems unlikely soldiers would call for a timeout to fix their ear plugs.


I switched from the 3M plugs to Pinlock plugs for most riding. The Pinlock ones are suitable for around town, twisties and short highway runs, but allow me to hear engines, sirens, conversations, etc. They slide in easily with a little water. I still use the foamies for long road trips.


Tangential but using water (which critically is not the same as sweat) to get earplugs in regularly would cause your doctor to have an annuerism.

I'm legit interested in this because I chase constant ear infections from needing to put in earbuds/plugs right after showering for my routine/work flow.

Have you ever had an issue?


I used to use water all the time to slide earplugs in, and never had any issues with ear infections. But I always had a nagging voice inside my head telling me it wasn’t a good idea.

Did I get lucky? Or maybe I’m just less susceptible to infections? I always made sure the water was clean, but I suppose if there were bacteria on the outer surface of my ear, the water would carry it inward easier than a dry fitting would?


It's luck, and maybe genetic thing.

Water cleanliness doesn't guarantee anything, bacteria is everywhere. Some scuba divers with the same technique get infections often, some don't (with same techniques). I got an infection on my first dive, then nothing ever again. Some get them every 6-7 dives.


> Water cleanliness doesn't matter, bacteria is everywhere[...]

It matters a lot, I've dived extensively, and the only time I've gotten an ear infection was in Indonesia, likely polluted runoff water contributed to that.

You'll find scientific articles backing that up, i.e. infections in general go up when swimming in untreated sewage/runoff, including ear infections.


I miswrote that. Water cleanliness matters, but it doesn't guarantee a lack of infection.

Sorry for the confusion.


Where in Indonesia?


Is it worse than having a bath where your ears go under water or a shower where water splashes into ears? Isn't that something many people do daily?


After a bath or shower, your ears are open to the air, and the water can evaporate.

The earplugs keep the water sealed in your inner ear for a long time where it can't dry, increasing the chance of infection.

Some people do just get more frequent ear infections than others, though, from swimming or even just daily showers/baths. That gets back to the luck/genetics thing.


Diving has total saturation and additional pressure driving the water deeper than water splashed at 1 atmosphere of absolute pressure.

Combat (or riding or flying) has longer duration of dampness than getting out of a bath/shower and going about your normal routine.


It doesn't take much. I just run them under the tap and flick most of the water off. It helps form a seal and then dries off. They always come out dry.

I can see how putting them in right after a shower can be worse since you might have water collecting in your ears.


Custom mold earplugs from a ENT or other similar vendor could be a good fit for you (pun intended)


Custom mold earplugs work _too_ well for motorcycling. They block emergency vehicle sirens.

I once got chased halfway down a mountain by a cop I couldn't hear (my KTM had nearly useless factory mirrors). Cop said he was leaning against n his horn and my foamies blocked it out entirely. Somehow I didn't get a ticket...


You can get ones with certain dB reductions instead. Those will allow you to still hear but at a lesser level.

This is great for reducing wind noise while riding, but still being able to use in-helmet comms and hearing things like sirens/honking horns.


You can also get ones that have interchangeable filters for different levels of protection (and they even make ones that are relatively "flat" across the audible band, which is great for movie theaters that have the volume too high).


Yeah this. Let them know what you're using them for and they'll tune the NRR and frequencies for your use case.


Custom ear plugs don't have a higher decibel reduction rating than foam ones.

They are mostly used for comfort and even frequency response.


I've got flange-shaped earplugs for the motorcycle, they seem to be just fine. Pulling up the ear is good practice for any kind of earplug though, I presume it straightens out the ear canal or something like that, I've used it for audio earbuds as well for a long time.

If they fall out, get different ones.

My dad had custom molded ones for his job (in metalwork), but that was well after the damage was done. He had tinnitus and he's now finally budged and got himself some subtle hearing aids.


You can do the custom-molded ones yourself now, I had some for motorcycle riding and they worked very well. Unfortunately the ambulance cut them off of me when I got in a wreck so they are toast now, but they did their job great up until then!

I used https://earfuze.com/ but I'm sure there are better ones out now.


Why not use a full head helmet with windshield?


Even a quiet helmet, at speed it's like a radio tuned to static turned up to a noise level just below painful. Windshields can actually make it worse, depending on airflow - turbulent air coming over the top and around the sides of the windshield is louder than clean smooth air. Windshields do more for fatigue, weather protection and aerodynamics.

I wear hearing aids due to motorcycle-related hearing loss, and I have never worn anything less than a full helmet.


That just does not work unless you have bubble around your whole body and I bet even then it’s sufficiently loud.

Unless you find the perfect windscreen, most have lots of buffeting and it’s actually quite hard to dial it in perfectly.

Helmets do absolutely zero to block noises.

Edit: just to add. I think it stands. The helmet does not block any sound. It may be aero dynamic enough that it helps prevent additional wind noise but it’s not blocking sound. Ear pro all the time.


It depends on the helmet and speed. When I got my Arai helmet, the speed where the wind noise is troubling went from 80kmh to 130kmh.


At just 30kph you are getting permanent hearing loss. https://www.noisyplanet.nidcd.nih.gov/have-you-heard/wind-no...


Cyclists typically don't wear full face helmets with wind deflectors.


the helmet makes the wind louder. Air slaps against the shell.


Said it in another thread but while sure it matters, it’s generally a pretty weak argument. It’s your ears and you can decide for yourself but even if it does not sound loud, over the course of a ride it can still be high enough to slowly cause damage.

To me it’s the same kind of argument of friends who would say it’s ok to shoot shotguns without ear pro. Sure it can be done but it adds up.


Maybe I don't ride enough for it to be an issue, but my hearing is top notch for a 35 year old.

I got tested and I'm at 20 y old levels of sensitivity.


And I don’t mean this the wrong way. Your experience is anecdotal. Maybe you ride in a city and slow speeds, maybe you have a windscreen that actually does decent job of creating a bubble over you, maybe you don’t ride for extended periods of time. Too many variables to account for. For the population though, ear pro is recommended for Motorsports. I had a bike once that caused buffeting from the hand guards. It might work for you but generally does not work for many.


If your Arai has the wind deflector in you are giving yourself oxygen deprivation at every stoplight. https://youtu.be/x_ej8sehs8k?si=9LtvP0TfhQzgNDVM


Never been an issue, and I'm susceptible to oxygen deprivation being a big guy with weak lungs.

I get dizzy in crowds, but never while riding.


My Shoei RF 1400 was extremely quiet. Supposedly one of the few helmets that you actually don't need ear plugs with unless you're going extremely fast.


I would be willing to bet the db was high enough to cause damage over enough time. It’s not just just the peaks but also the duration. I would be very surprised if generally helmets provide much if any meaningful db reduction.


Full-face helmets are still very noisy at highway speeds


Just 18mph of wind is enough to cause permanent hearing damage. Windshields and helmets don't block enough of the air (the rider needs some air ventilation for defogging in cold weather and cooling in hot weather.)

If you try to fully seal the helmet you cause measurable oxygen deprivation. https://youtu.be/x_ej8sehs8k?si=9LtvP0TfhQzgNDVM


If there's any airflow (and there better be for breathing and ventilation) there's wind noise at speed. You're always better off with plugs.


You might be shocked to learn people have tried that :)

It's hard to believe the amount of road noise on most motorcycles. It's not really comparable to rolling down the window in a nice modern car with good aerodynamics.


Is it legal to wear earplugs while riding on public roads?


Not only legal but strongly encouraged by our instructors to prevent hearing loss. There are riding specific earplugs tuned to block the wind and road noise more than sirens, horns, etc


It might surprise you to see how many states it is illegal in (IIRC it's close to half). This may even include states in which the motorcycle school instructors tell you to wear earplugs for hearing loss.


That isn't the case. The majority of the states have no law and a good chunk of the others have exceptions for hearing protection. A lot of the websites online have outdated info- e.g. most websites claim CA and OH ban earplugs, when this clearly isn't the case.


The California carve-out for hearing protection states: "The plugs or molds shall be designed in a manner so as to not inhibit the wearer's ability to hear a siren or horn from an emergency vehicle or a horn from another motor vehicle."

Ohio has a carve out specifically for motorcycles; operators of vehicles cannot (I used to own an RV where the wind and road noise at freeway speeds was well above safe levels for sustained operation).


In United Kingdom it's even recommend.

I dont agree that calling someone ignorant is a personal attack, or name-calling for that matter. if I had said "you're an idiot" it would be different, but ignorant is a fairly polite language, that somewhat distances from the sphere of "personal attack", and removes any accusation of motivation and bad intent entirely.


I hear you, but if that was your intent, then you weren't communicating it clearly, because calling someone ignorant in an internet comment is guaranteed to come across as a personal attack.

Moreover, "spewed BS" was name-calling and also guaranteed to come across as a personal attack, and in this context, one can say the same about "I feel sorry for you". That makes 3 swipes in just a single comment! Please edit out such things from now on.


> The majority of motorcycles are deliberately loud

this is peak reactionary nonsense - that majority of motorcycles are stock bikes from the manufacturer, ie appropriately muffled. like with absolutely anything else in life: you don't notice the ones that are muffled and thus, conversely, you assume the majority aren't.

> I can't say I have much sympathy for motorcyclists losing their hearing

it's just so weird to me that people will voluntarily be spiteful like this. like does this make someone feel good? to proudly proclaim their spite? i must've watched too much disney when i was a kid because when i'm spiteful i feel bad.
