Subreddits have dropped off too. I assumed the migration was to discord or tiktok or other plublic squares.
Specialized forum content, discussion and community suffered with the VerticalScope rollup that borged them all a few years back. They immediately upgraded the forum software to be phone app compatible (more eyeballs) and forum quality died soon after. No one is have good discussion, arguments, stories or history while phone posting on the can or in line at the DMV. It is all repetitive drive-by comments or questions that could be answered by a quick search of the forum so it is short attention span theatre now. I saw this across multiple forums that got rolled up by VS.
Interesting post. I noticed that your Optimal: L=2997mm is the same four leading digits as the speed of light 299792458 m/s.
I always thought there was a connection between geometry and the math and physical constants. Once I was thinking about Einstein's equivalence principle between gravity and acceleration and his elevator-in-space argument. He claimed that there is no experiment that the man in the elevator could do to determine if he was in a gravity field or accelerating rocket. It occurred to me that all he had to do was wait because the rocket could not accelerate at 9.81 m/s forever. So I did the math lightspeed/acceleration of gravity = 30559883.59 sec = 353.7023 days for 86,400 sec/day or 96.9% of a year to get to c. Just a coincidence, they say.
Holy... i hadn't noticed the speed of light thing!...collab with me if you like. i'm super stoked for engagement , even if someone disproves it all. :)
TY!
I think that now that IPV6 has 2^128 addresses that some of these can be assigned to individuals as a unique ID, maybe at birth like SSN. It could serve as the base of a public key and secret private key blockchain system controlled by the individual or his trusted agent in some kind of identifier/authenticator system. If properly implemented it could serve as an anonymous ID and age verification system on the internet which seems to be coming soon in a not-so anonymous form to a fascist, commie or authoritarian govt near you, i.e. all of them as current events now show.
I don't know if that would work but it is an interesting idea to me. However, it also illustrates that authentication and protecting user identity on the web without sacrificing anonymity is a _political_ problem not a technical problem. I have always been told that when thinking about security you have to define what threat are you trying to protect yourself from. I see discussions on security and virtually all of them ignore that the govt or govt controlled corps (i.e. fascism) is a much bigger threat to individuals and freedom than so called "hackers" or "terrorists" and other boogie men, etc.
The best advice I got on breaking a bad habit is that you can't do it by ordering yourself "don't do X" which takes will power and teeth-gritting effort. Any success with this method will fail over time. The problem is that it is like telling yourself to not think about pink elephants which makes you think about pink elephants.
So the trick is to set the rule [don't do X, do Y instead] and immediately stop thinking about X and move on to Y. Just shut down the "do X" thought and shift to Y. "Y" can be anything even the absurd like patting the top of your head 5 times because it breaks your subconscious programming. In fact, the absurd Y's seem to be more effective BECAUSE they a silly or ridiculous. Of course, as you gain skill at this method you can start using more productive Y's like doing 10 pushups or do a quick household chore, do a small task on your to-do list, etc. Once the subconscious program is broken then thoughts to do X will fade and you can move on to X2 that you want to change.
You don't actually own your phone if ownership implies control over your property. You just get to pay for it. This was always the goal of our corporate/government "partnership" AKA fascism.
Can't wait for Windows 12 to have a mandatory S-Mode and a Microsoft account tied to your PII, for your protection. No anonymous writer can publish the 21st Century equivalent of the Federalist Papers and our tyranny is safe.
Absolutely. The closest analogy is the social upheaval and changes in societal institutions resulting from the printing press. Read Clay Shirky's "Newspapers and thinking the unthinkable" for a sketch of the impact of the internet.
I used to design PID process controllers in industry. In watching this vid I realized one reason that designing a self-driving car is so difficult. Toward the end, in the process control diagram, he has [Vehicle] as the controlled process. This reminds me of the old math joke about "assume a spherical cow". The difficulty with a self-driving car is that it isn't just the vehicle that has to be controlled but [Vehicle + Current Road] so the controlled process is not just difficult to model but that it is changing all the time and sometimes rapidly.
I think learning it all on your own is not efficient even for a genius. At the very least (assuming you are a genius) you should do a double major in Electrical Engineering and Mechanical Engineering and a minor in philosophy at a mid- or top-tier university. EE and ME are the practical expression of the foundation of classical physics. Einstein's early work was related to integrating these two fields. In short (I am a bit sketchy on the exact details since it has been a while), before Einstein there was an odd inconsistency in Maxwell's equations whereby the results differed if the magnets were moving or the coils were moving in generating electricity. Since all motion is relative, at least mathematically, it should not matter which was moving. Einstein's revolution amounted to modifying the concepts of space and time (using Lorentz transformations) to make that inconsistency go away BUT it is possible that that is not the only possible solution to the puzzle. Once you get your BS degrees you should get your PhD in physics at a mid-tier school or no one will listen to you.
The reason you need to minor in philosophy is to understand the history of the field going all the way back to the Greeks. Most importantly, you need to clearly define a theory of concepts and apply it to fundamental concepts such as existence, consciousness, free will, space and time. Current physics (and math, btw) are vitiated by inconsistent fundamental concepts. In fact, Einstein's concept of spacetime is a denial of consciousness (an axiom) and a deadend. The fundamental concepts in physics should be lightspace and gravitytime to avoid this error. You won't learn much in modern philosophy courses in regard to these issues but you need to understand the history and read Ayn Rand's Philosophy:Who_Needs_It, Introduction_To_Objectivist_Epistemology and the title essay of her anthology For_The_New_Intellectual.
Hard agree on the EE + ME foundation. Most physicists reach their limits because they don't understand parallels between or capabilities of different established domains of applied physics. Plus, engineering gives you good advanced and backup job opportunities.
It is always easier to find a job when you have a job. Once you have made the decision to leave then putting up with the on-the-job BS is psychologically easier because it reinforces your decision and you know that you are working on getting out, hopefully soon. Also, in today's environment (lots of tech layoffs incoming) it might take you a year to find a suitable alternative. Make sure you have some savings for the transition, brush up your resume and start networking with friends, asssociates or a head hunter. Do not bad mouth your current employer in interviews and don't tell your employer or any coworkers, that will move you to the top of the layoff list if word gets out.

tldr; Vertical Scope and phone app use.
