Nah, it is a matter of weight. Roads are engineered specifically for the weight of these trucks. If these trucks are regulated stupidly, the cost of goods goes up very quickly, the cost of road infrastructure skyrockets, or both. Making cars obese to protect the dumbest humans is one thing, but the constraints are different here. A commercial driver’s license is supposed to be a real license with real qualifications. That is your only protection. In a society where driving is required, the regular license is a joke with superficial qualifications. It is just a tax on the populous.
- Comment on Is it normal that you feel very shaky as soon as you start to get hungry? 10 hours ago:
I do the shaky thing too, but I think it is just psychological tbh. At calorie crash levels of no blood sugar during extreme endurance sports, it is totally different. It is like someone straps lead weights all over your body. Everything feels heavy and nearly impossible to move.
There is probably some kind of dynamic regarding different types of sugar in the system that cause the shakiness.
Your brain ONLY works on sugars. So calorie crashing, like hitting the wall, is when your body has to start cannibalizing your own muscles for sugar to fuel the brain. I’ve never been anywhere near that level except on a bike after 4+ hours and 60+ miles. You feel like a puddle, and joints are like bending copper wire. There is no shakiness in that state.

Anyone here ever driven in a runaway trap system?
I was mildly scared of them when I was getting my commercial driver’s license ages ago. I was looking at potential jobs involving cranes or an excavator and lowboy. When a typical tractor trailer is fully loaded, you only have 3-4 full hard presses on the brakes before you lose them. Air brakes are inverted. The unpowered brakes state is fully engaged. The pneumatics are holding back the shoes; unlike typical cars that are pressing the friction material into a surface using hydraulics. When a truck fully engages the brakes, it lets all the air out. Then the reserve is used to refill the system to disengage. The engine’s compression is a primary component of the braking system. However, it is a manual transmission. Unlike manual cars, these do not have synchromesh (small clutches that spin up the secondary gear shaft to match the primary shaft speed). If you miss a shift, you only have around a 50-75 RPM window where shift will mesh at all. On top of that, the engine only revs 2k-3k RPM, so the transmission is usually an 8 speed with 2-3 splitters. That means there are 16-24 speeds total, and for any given speed, only one little shift window exists. I was scared of big downhills. When a truck is fully loaded, going down hill, and you’ve got to shift for engine braking, it can feel about like someone is fully depressing the accelerator in a regular car. That shift window passes super fast. One can rev match the engine to a small extent, but it is still easy to miss in an unfamiliar rig. You are more focused on staying in the lane when every visual indication you’re used to in cars is missing. Like you feel much larger than the lane and you only have around half a meter of extra margin split on both sides of the truck when driving minimum width lanes. So you miss the gear mesh, now you hard press the brakes to get the speed somewhere low where you are able to find a gear. Miss like that 3 times in a few minute span, and you’re likely to run out of air. That slams on the brakes, but that is not enough to stop a fully loaded truck on grades steeper than 5-6%. It is why the signs exist warning about the grade. You must use the engine AND brakes at these grades, managing the air levels in concert with the RPM and gear selected.
Anyone here ever fucked that up, or been in to a runaway ramp or engineered stopping surface?

That is where you are projecting nonsense into my words. I only speak for me and my experience. I never presume to speak for anyone else. I know what I do not know. I never claimed something was universal. I claimed that your universal is offensive and prejudiced me while trying not to be confrontational about that. If you wish to experience the misery I went through that is entirely up to you. Such is not universal. An intelligent person learns from their mistakes. A wise person learns from the mistakes of others. If they choose to listen or ask questions, sharing my experience gives others the chance at wisdom from what I have learned the hard way. I believe toxic and harmful relationships are universally bad. You are welcome to dispute that if you would like. If you are advocating for harming others, such spurious sadism is rather malevolent and disgusting from a sadistic type of person that lacks many levels of self awareness. That is most unlikely. Much more likely is the possibility you are projecting your own misery onto others, and if that is the case, I am sorry for your misfortune. I do not wish to state what is or is not. I am aware I do not know you and I certainly do not wish to steal your narrative voice.
For someone in a position like myself, I am not conventionally disabled. I am fully mobile, but unable to sit up or stand for more than a few minutes. Both are the same to me. I must stay laying down most of the time. I cannot even get dressed and travel someplace and retain any meaningful part of myself. I am in constant pain that never fades, and I will die young and in terrible misery. I love some stranger I have never met enough to avoid them. I do not wish to be their burden, to watch me falling apart and die young. There is no foolish fate in the world. No one is at a loss if I abstain. That is a special circumstance. Still for others, before I was like this, I would have been much better off if I had simply explored my curiosity and interests. The people I met along that path were many orders of magnitude better for me than those I found while looking.
- Comment on Anon tells a true story 1 week ago:
You don’t understand what I have said. The idea that people must partner is nonsense. I am not required to be a beggar. Implying that everyone must pair is nonsense. I do not care where people meet. Being happy with yourself if far more critical when it comes to building a good relationship. I have been in many long term relationships. When I was young, I made the mistake of thinking I had to “find someone” and compromise. That was one of my dumbest moves in life. The idea that this is normal is idiotic and a main reason people get in terrible situations in life. Work on you first, then you will find someone that intersects your life in naturally compatible ways. If not, that is fine too. Going looking only results in finding people that like to go looking. That results in misery unless you want to spend your life looking.
You are also inferring that my preferred sexual orientation as asexual is invalid. That prejudice is offensive to me in its primitive lack of self awareness and depth.

I never said that. You are crazy. You have no grounded scope of the subject as a whole. I’m talking about far more than you realize, but have no way to fix your ignorance because you have multiple errors stacking and have not given me enough information to diagnose those issues. I do not mean any of that as an insult or to be mean. I was young and ignorant too. You have made assumptions that are incorrect, and I would like to help but cannot.

Anyone can detect any transmitted radio signals. The ARRL books explain how. I’m too lazy to go look at my copy to photograph the section of the physical book in my room. The frequency licensing is totally irrelevant here. That will just be changed and noise will get broadcast over the band. If you keep trying to transmit, someone will find you. You are literally creating a beacon in all directions that points at you. Everyone will be listening, but one by one there will be no one to listen to. This is standard stuff. Every military unit has radio counter measures. You are very limited in real output power already. The big boys will blow you away because they have no such restrictions. It is one of the reasons why there are power limits. Now if you can hide something useful and encrypted near the noise floor, that is one real possibility, but in this age of software defined radio, you are still going to get caught.

Meshtastic is still radio just the same. It is a transmitter and will get triangulated, but that is irrelevant to what I said. What I am talking about is how all radio devices you actually use are easily logged. Cell towers are one way, but the device is easy to log more locally. For instance most big retail stores are logging people in the door and their movements. Heck, it has been a few years since the papers about how people can be tracked based on changes and response times within WiFi coverage using standard consumer hardware. It would not surprise me if this is used by some now. The air tags nonsense, that is the same type of thing. The real reason you do not have removable batteries in mobile devices is so that you cannot turn them off. They are never fully off. That is how stuff like air tags still work. Stuff like Intel’s ME, AMD’s PSP, and ARM’s TrustZone are the systems that are used. It is a whole extra operating system running in the background on your hardware. These have a lower root level access to everything on your hardware. It is trivial to log signals from all mobile devices that pass a given point. It may still require some coordination to correlate cellular and video manually but I highly doubt that. In all likelihood, the current generation of hardware is already collecting this data. Look at all the stories of people getting caught a few days after crimes. That was unheard of 2 decades ago. Now it is practically a given. If you are in public and transmitting radio signals now, you are fucked. We would all need to dress up as Tusken Raiders to have any chance at anonymity now.

Radio is trivial to triangulate the broadcaster if someone tries. You can receive anything, but not transmit. If you have line of sight, lasers can be focused to some extent to limit scatter.
One of the biggest changes in Ukraine has been attaching a very thin fiberoptic wire to drones for their connection up to a few miles away. That is evidence of what is truly required and pragmatic. So, start running similar lines if you really care and can come up with a way of hiding them. The only real option is to go dark in practice. There is no way to stop from being forced into becoming a slave in all but name.

More junk stalkerware getting pushed. Try putting up a DNS white list (default blocking) firewall and then try white listing their servers.

Like if you need it for some reason, a virtual machine or separate hardware device and network are pragmatic.

Start with Plato’s writings about Socrates. Republic, is widely considered the best. You can listen to lectures like this old (one from Professor Sergue of Princeton YT)[https://www.youtube.com/watch?v=8rf3uqDj00A] from the 1990’s. Note that the late Professor passed a few years ago, so naturally YT promotes it because it is high quality content, in medium/low resolution, and no one is likely claiming the revenue. In other words, do not feel guilty about using Pipe Pipe, and perhaps just download a copy to keep on hand. That is a rather good 3 part lecture series. This is something your local library will have in book form. If you search for “mass market paperback” with Plato, you are likely to find new books at around $5 too. These generally have more updated text than gutenberg.org, but that has several options too.
Developing a philosophical mind and independent ethos like Socrates will do much to help you develop in very useful ways, both inside and outside your bedroom.

Good neoteny is forward slant to the face, near perfect symmetry, small nose and mouth, and a head to body scale of one to five.
The point is that most people cannot differentiate faces by descriptions well. There is a lot of translation involved between all the faces they know and those words. Facial recognition is much faster than word recognition in the mind. With strangers that have separate motivations and priorities, it is nearly impossible to effectively communicate this.

Bikes are anonymous, especially road. No one is watching or paying attention… Part of the problem too, but still. I’ve been through some shit on a bike, but honestly still recommend it 10/10. The odds of you encountering some political refugee with a third grade education and a four page long driving record are nearly zero. You will never learn an area like you will on a bike. I have been all over Orange county and have ridden a lot of Los Angeles, Riverside, and San Diego, all from just starting from home. I know places on a different level than most people, like I know the bike trails, back roads, fire routes, parks, military bases, and all the way down to connections that are not intended like through golf courses, sidewalks and stuff. I know of a bunch of eclectic pastry shops too because I would make them destinations to push up my miles. Like, today I’m going to hit up a Persian place in Tustin, then a French shop in Huntington Beach before heading home for an 80 mile day. It takes awhile to build up that kind of strength, but only around a year. It is the ultimate freedom.

Don’t get in this kind of trouble… Lasers do a remarkable and very disorienting job from a distance.

I’ve had asshole kids shine one at me commuting by bike at night. For a solid second or so, you will lose vision and be disoriented. Even a halfwit is not going to crash in that timespan, but it feels like someone turned off your brain for that second, like next level overload nonsense.

- Comment on I’m not saying that I agree with right- or center-wing views, and I do condemn transphobia. However, do you think there should be a distinction between critiquing beliefs held by transgender people, and engaging in transphobia? 3 weeks ago:
No. I think transgender people get more than their fair share of a shit show and deserve safe spaces free from any lines in the sand of others. Ultimately no one has a rich to project their beliefs onto others.
You have a right to all information sources, a right to skepticism, a right to error, and the right to protest in all nonviolent forms aka the right to offend others. Your rights never include infringing upon the rights of any other.
The idea that others are subject to collective critique is nonsense conjured by religious backwardness. I came from such an upbringing too. That is the toxic nonsense you need to try to purge. The peer pressure, negative feedback loop, and shaming only leads to problems. It is not real ethics or morality. It is a tool to get you to outsource your morality and ethics to a dubious source, and ultimately to have nothing more than a fear of getting caught. It is a system that fails at basic game theory; a negative feedback loop is incapable of producing positive outcomes. You cannot amplify from unity gain or attenuation. So ask yourself, is this a negative feedback loop. If the answer is yes, and you have nothing positive to amplify, then all you are doing is death by a thousand cuts and bleeding someone further. Be a positive force in the world and maybe just maybe you will have positive outcomes too.

It is every military. That is what makes a good military; meritocracy above all else. The success many countries experienced after total war was due to weeding out those that lack merits.

It stops the flow of money effectively pulling it from circulation and bringing everyone down.
