@REDBURNBARREL @Orange_13241 @tommeyer1216 @snoproscott The sidewall of a tire experiences repetitive forces that cause it to flex every time the tire rotates. For every mile, that flexing occurs over 700 times. The tread flexes a lot less during driving and has additional, much stronger belts to prevent deformation.

@Orange_13241 @tommeyer1216 @snoproscott Right, but why won’t it hold compared to the tread

My toxic traits say it looks easy and I can do it myself

@AuggieBeee @snoproscott Holes in sidewalls are not safe to plug or patch. These types of repairs might last to the repair shop or fail at any time. It is safer (and could ultimately be faster and cheaper) to use a spare or call for help rather than risk an accident or vehicle damage.

@snoproscott These temporary plugs are fine for the sidewall. The package will tell you not to do that, but that’s just because they can’t legally recommend it. Pop one of these string plugs in, drive to the tire shop, and you saved $150 on a tow

@LivingTricks_ And, one of the least comfortable too. ;)

This might be the simplest chair ever made 😏

@PatrickETash @MachinePix The copper conductor is generating alternating magnetic fields that induce eddy currents in the teeth of the gear. The ceramic coating on the copper wire is likely to electrically insulate and protect the copper conductor.

@MachinePix Is that a resistive heating element?

Induction hardening teeth of a gear.

@joshmugayi @Rainmaker1973 We have 230kV and 500kV lines nearby. Most people cannot keep both feet high enough off the ground to prevent arcing through the air to the legs at 230kV. Nobody I know can at 500kV.

@Rainmaker1973 But when you running both feet rarely make ground contact at the same time? 🤔 (& You get out of range faster)

Here’s why you should never run if a high-voltage power line falls

@SaintOfStocks @Rainmaker1973 High voltage transmission lines carry sufficient voltage to break down the soles of everyday shoes. Even if it doesn't do this, it can follow the dirt, moisture or even the air around the soles. These voltages have no issue bridging past the shoes to your legs.

@Rainmaker1973 But shoes are bad conductor of electricity… y should we bother until unless on bare foot?

@ibenaija @lubuwargod @HotSotin Sorry for the belated reply. I have been busy with work. Item #1 is a disputed premise, but not necessarily a logical issue. If we disagree on this premise, then that would explain our difference of opinion. Item #2 is an inference that assumes many things.

@AstroPythagoras @lubuwargod @HotSotin Two logical issues: 1) you’re assuming we agree market economies are successful. “Successful” how defined? 2) if market economies are “successful” as they would define success, then they would have copied it fully. They didn’t.

Crazy idea: Let's split a country in socialist and capitalist halves and check in on them in 75 years.

@EthandHale @AJamesMcCarthy @tintintar I agree that having new players opens new possibilities. For clarity, my original concern was with the notion that SpaceX is "carrying NASA's lunar landing missions on its back." SpaceX does amazing things, but it's important to recognize the path already blazed for them.

I don’t think I was extrapolating too much, just taking your statements at face value and addressing your direct claims. It felt like you weren’t always addressing my actual argument and did some shifting of the goalposts. I see a lot of SpaceX FUD that seems reflexive and a bit over the top in response to relatively tame statements of hope about Starship progress. It’s important not to discount new platforms and entrants to manned space flight and allow these programs to finish testing and prove themselves before judging them.

And defund SpaceX and the other scam private companies doing ’space exploration’.

@EthandHale @Brett_327 @AJamesMcCarthy @tintintar You seem to be extrapolating a lot from what I have said. I am not anti-SpaceX. I believe they will play an important role in the future of space flight. SpaceX stands on a foundation of decades of NASA research and expertise and continues to push upward.

Regardless, your claim that SpaceX doesn’t have an established record carrying humans to/in space doesn’t hold water by any stretch. Comparing manned flight count is one thing, but discounting their entire portfolio of manned missions to make a point about Starship is pretty much just baseless slander. Also, by your logic we should never develop new companies or new platforms and should only ever do the thing we did before. That’s just not how technology innovation and evolution works. SpaceX has a pristine safety record with manned missions. Starship test launch RUDs are not foreshadowing of the platform’s safety for manned missions. Its testing to failure, which is very common in most competitive manufacturing industries. Hell, Apollo actually lost lives during ground testing.

@ibenaija @lubuwargod @HotSotin This is somewhat true. However, many of the economic reforms they implemented were motivated by the observations of success in market-based economies.

@AstroPythagoras @lubuwargod @HotSotin My point is that they have devised their own economic model that is not a copy of what America/the west wants to impose on places like Cuba.

@EthandHale @Brett_327 @AJamesMcCarthy @tintintar Yes, NASA shifted from more direct design, engineering and oversight to more of a contract-it-out model. NASA has launched 160 crewed missions. Two failed. Failure rate: 1 out of 80. SpaceX has < 25 crewed missions, arguably too small of a sample size for a valid comparison.

If we’re doing math, I’d encourage you to compare the fatality rates between NASA (which really means the defense primes) and SpaceX manned flights. Also consider that comparing “NASA” generically to any company doesn’t make sense since NASA itself doesn’t build rockets. SpaceX HLS will be a “NASA” rocket when it flies next year, just as much as SLS is. Last thing I’ll say is that it’s really not a good faith argument to compare unmanned test launches to the manned Apollo and Shuttle programs, each of which had multiple major incidents, including deaths. If HLS killed someone I would not defend it, but since that’s not the case, this really deserves a more honest perspective than what you’ve given.

@EthandHale @Brett_327 @AJamesMcCarthy @tintintar Carrying humans requires more than science. How many humans are going to volunteer to fly on a platform that had a 100% test success rate in 2024 followed by a 40% rate in 2025? NASA has an established record carrying humans. SpaceX does not. Astronauts can do the math.

HLS mission is next year and Starship has already flown a dozen times at cost to SpaceX. I have no ill will toward Blue Origin, but they’re demonstrably no closer to landing anything on the moon than SpaceX is, and they have a terrible launch cadence. SLS was nowhere near ready for the first several mission plan dates and taxpayers funded every delay and cost overrun. Starship V3 flight will reset expectations.

@swageir @NotThatHughes At any point in time, about half of the moon is lit and the other half unlit. We just see the portions of these facing Earth. This is the same for those looking at the Earth from a distant location.

@NotThatHughes How is that a stupid question? This is current moon phase from earth. It’s 75% lit. Meaning the opposite side from earth should be 25% lit

I love the notion that, because she was an English major, no one ever taught her about the sun.

@AwareFelis @kanavtwt The last embedded i486 cpus were shipped in 2007. A device that is 20 years or more old can still function using the same Linux version it already has. We have an old robotic arm that only runs on Windows 2000 or XP. For security, we block it from accessing the Internet.

@kanavtwt This will prevent old computers from running Linux. And by old computers I mean specialized hardware that don't get replaced as often as consumer hardware, like MRI Scanners or ATMs.

can a hardware expert tell how bad is it

@ibenaija @lubuwargod @HotSotin By officially embracing open markets and private ownership into their economic model, China has moved significantly away from the ideology that underpinned the revolution of 1949.

@AstroPythagoras @lubuwargod @HotSotin To be sure, how’s this different from what you’re responding to?

@gisellaesthetic Life isn't perfect. That's what makes it beautiful. The original looked fine to me.

I prefer retouching that retains the original characteristics of the photos to heavy editing.

@ibenaija @lubuwargod @HotSotin From the PRC constitution: A1: "The [PRC] is a socialist state..." A15: "The state shall practice a socialist market economy." Economists consider China to have a mixed system, though they call it by different names (e.g. socialist market, state capitalism, party capitalism).

@AstroPythagoras @lubuwargod @HotSotin Definitions matter. China is governed by the Chinese Communist Party, and its official ideology is still rooted in communism. That they’ve woven elements of markets and private ownership into their model is indicative of their genius.

@TansuYegen Triangles for the win!

This is how architects are chosen: one spaghetti truss at a time, until their dreams literally crumble under a bucket of sand. 😭💀

@ibenaija @lubuwargod @HotSotin I can call myself a brain surgeon. That doesn't make me any more a brain surgeon than I was before.

@AstroPythagoras @lubuwargod @HotSotin You guys like to have to both ways. It’s a communist nation definitionally. It is run by a literal communist party.

@audreybbonbon @angns @lisa_vaill @DrNeilStone Diagnosed cases of autism have increased. This is because the definition of autism has been significantly broadened in the last 30 years. At age 6, I was tested for hearing loss (I hear just fine). Today at age 6, I would likely be assessed to see if I am on the autism spectrum.

@angns @lisa_vaill @DrNeilStone Already done so in another part of the thread. If you’re arguing there has been no increase I’m afraid you’re deluded.

I'd rather my kid didn't get deaf or die from measles So I got them vaccinated And they are not autistic (which has nothing to do with the vaccine)
