Shear Pins are Smart (They're Mechanical Fuses)

Payback says...

He says he's "done for the day" because of it. Probably intends to get a new shear pin "tomorrow" and continue mowing. Depending on how far away everything is, it could be more efficient to avoid two extra tractor trips just to repair a pin.

I'm still at a loss on why he's waiting for a ride? Disconnect the tractor from the equipment, drive the tractor back... Heck, I'd think even once the PTO shaft was disconnected, he'd still be able to tow the equipment back using the tractor.

EDIT: Of course, I'd guess it would take a few tools to disconnect the equipment so it could drive back, or tow... so perhaps that's what he's waiting for, tools, not really just a ride, and then tow the tractor and equipment back...

Kurzgesagt - Do Robots Deserve Rights?

scheherazade says...

Thoughts,

IIRC the main argument against women's vote was that it would in effect give married men two votes (the expectation being that the wife was subservient to the husband, and would vote as she was told). AFAIK it wasn't because it was something difficult that needed to be taken off of their shoulders.

In actuality, if we stopped eating meat, we would stop breeding all the food animals (because who's gonna pay for it?), and it would be a massive near extinction event. It's not as if these animals are in the wild anymore, and most have been selectively bred to such extremes that they would die in nature (cows producing so much milk they would damage themselves if not milked, and sheep producing so much wool that they would die of heat if not sheared, etc). If using population as a metric, food animals are some of the most successful creatures on earth.

Introducing Handle - new research robot from Boston Dynamics

newtboy jokingly says...

I would like to ask you to think twice before signing up to be a test subject to help in developing robotic hand jobs. Wait until they have it perfected......unless you LIKE industrial hydraulic press and shear level forces applied to your penis, then do whatever floats your boat (but don't whine to me about your flat, mangled, or missing peen...I warned you).

Mordhaus said:

Misread the title initially, thought it said Handie, new research robot, was like "How does one sign up as a research subject?!"

THE CRUELTY BEHIND OUR CLOTHING - WOOL

transmorpher says...

That's the scariest bit. On the surface it looks like a peaceful farm, because when you're going past it, all you see is lovely green grass and sheep grazing, it looks lovely and peaceful.

You don't get to see the castration, horn removal, tail docking and mulesing without any sort of anesthetic - this happens to every single lamb.

You also don't get to see the workers having a bad day and abusing (after the product is removed from them). This might not happen to every sheep, but with around 30 sheep getting sheared an hour by each person, you can bet at that speed it's not a pleasant experience even without malicious intent.

Outsiders just see a lovely country side, with sheep grazing before and after the abuse.

newtboy said:

Having just come home from visiting Iceland, and after visiting farms there, and also farms in New Zealand, I can say unequivocally that most farms in those countries are what you think of, peaceful sheep in large bucolic fields enjoying their lives and not being injured during once a year sheering of wool that's otherwise a problem for them to shed naturally. I won't speak to Australia, since I've never been there...maybe all sheerers are dicks there.

Insane Bus Crash Aftermath

SFOGuy says...

I thought...well, I know, that some light poles are designed to shear off at the base...I suppose you really can't do that do a sign post that large...

bobr3940 said:

That is one heck of a pole they hit. Sheared through the front axle, tore through about 2/3 the length of the bus and was stopped by the rear axle and yet the sign appears to be still vertical.

You are once again mistaken....
Real verified stats are had to come by, but: "In the coral reef community there are many species of fish which fill this ecological role: roughly 25 percent of the fishes are herbivores or make plants a part of their diet/omnivores (Deloach, 1999)."
That's just fish, far more abundant than land animals by number or biomass, as a group are at least 75% carnivore (not omnivore).

"obligate carnivore" is not honest, scientific, or reasonable. That means 10% CAN'T eat plants, not that only 10% does. Most animals are neither pure vegetarian or carnivore. I know vegans have a history of ignoring omnivores as a category, because it erases their positions/arguments, but that doesn't mean it's not a major category, in fact it's THE major category.

Herbivores have digestive systems designed to break down cellulose. Humans have one stomach, not designed to break down cellulose, so if it's a choice between carnivore or herbivore, biologically we are carnivores, which makes removing the omnivore category just plain silly for vegans.

Why Are Aeroplane Wings Angled Backwards?

radx says...

About the X-1 being the first manned vehicle to break the sound barrier: there are records of Bf 109Fs surpassing 950km/h TAS in a dive when they tried to solve the issue of elevator and aileron lock-ups at very high speeds. I wouldn't call it far-fetched to assume that both G10 and K4 could surpass Mach 1 in a high-altitude dive without the wings shearing off. Alas, no proof. Just an interesting bit of aviation.

Super Crazy Accident

YEEEEEHAAAAAAW!

AeroMechanical says...

Wow. That was awesome, but could have easily knocked a big hole through that ugly building (probably an orthodontist office). A win for aesthetics, but a loss for the insurance industry.

And is that a big trail of diesel its leaving behind it as it slides? I approve of this stunt in its entirety. The world needs more ridiculous stuff like this just for the shear stupid fun of it.

star wars prequel-nostalgia critic gets owned by Mr plinkett

Jinx says...

Couldn't agree more on the lightsaber fights.

I think it was Lucas himself who asked that the lightsaber should be moved as if it had real weight even though it was made of, well, light. I think the fact the actors appear to have to exert themselves to throw and parry blows makes the whole thing seem more intense despite the slower pace of the fight. Vader crumbles under the shear force of the enraged Luke's blows - does anybody ever get overpowered in this manner in the prequels? I understand this logic that Jedi at the height of the Republic would be more skilled with a blade, but it results in two characters flailing around striking the air in front of their opponent with blows that appear to have no force behind them at all.

Sheared

Your Tax Dollars (Hard) At Work.

eric3579 says...

MUSKEGON COUNTY, Mich. — A Norton Shores man was arrested Sunday after leading police on a chase on his moped.

Norton Shores Police were dispatched to a home on Reneer Avenue west of Leon Street after Richard Shear, 28, allegedly threatened his mother and girlfriend with a sledgehammer and a knife and tried to set the house on fire.

Sources tell FOX 17 that the suspect’s mother called police after he threatened her with the weapons.

He`s accused of threatening his girlfriend too, but she told FOX 17 that never happened.

Sources also tell FOX 17 Shears attempted to light the house on fire by pouring gasoline on his landscaping then throwing a candle.

They say he also slashed an SUV’s tire before hopping on the moped and fleeing.

As FOX 17 took a closer look at the incident, we learned Shear has a history of drunk driving arrests, but we’re told he is also seeking help for mental health issues.

We’re told Shear, just like many other servicemen and women, suffers from Post Traumatic Stress Disorder (PTSD), a result of his time spent serving overseas in Iraq during his eight years in the Marines.

Those close to him tell us he has been struggling with PTSD, abusing alcohol to prevent dealing with the deep seeded issues and hitting rock bottom on Sunday.

Police say the chase ended back at Shear’s home when he tried running back inside but was arrested by police.

His bond has been set at $100,000.

A little bit about Anti-Theists... (Blog Entry by kceaton1)

kceaton1 says...

BTW, I wanted to add a small comment at the end of this. Something I didn't add back then (but, looking back upon it, I think I should have).

It is regarding the little comment I mad e about feeling a connection to "something" bigger than me, then describing what this "feeling" was like.

I wanted to make it clear that the human mind, our testimony, and our eye-witness accounts are very, very undependable... A sad, but absolute truth.

Most cases that have been thrown out of court later on--once new evidence is brought to light; like DNA evidence--has shown over and over again that in many of these cases, the "victims" or prisoners sent to jail--for doing nothing--were sent there almost entirely on eye-witness testimony and accounts. Then the DNA shows that their entire "story" (because that IS exactly what it should be called), merely served as a way to put an innocent man in jail, and to keep that DA/prosecutor's record as close to "awesome" as possible (because we really DO care FAR too much about a DA's record than whether the person being prosecuted should actually be here, let alone if they are guilty or not). The defense attorney has the same problem; I'm not really sure WE should care about these things (only so much as to whether the state IS actually bringing cases to court that SHOULD be there...).

I have severe sleep apnea and also narcolepsy. With this I get sleep paralysis (basically every night) and an extreme amount of hypnagogic hallucinations (more than powerful enough that i fully understand why many believe in both ghosts and aliens--amongst other creatures). The "feeling" and situation I described above can very easily be traced back into this little issue of mine. It creates everything you could imagine--I even had a hypnagogic hallucination powerful enough that it felt as though someone or something was trying to yank me "through" my bed (hello, Nightmare On Elm Street"--I was actually more intrigued by the event than anything else, akin to a researcher). While most people would have run yelling from there house, or at the least gone to get comfort and forgone sleeping in that room AND bed for quite sometime...I went right back to sleep.

This is why KNOWING what you are up against, what it can do to you, and how powerful it really can be (especially on your psyche and even your physical state is very important...). I knew all of this before it ever happened AND I had also noticed the hypnagogic hallucinations doing A LOT of very small auditory based things--all the time--to me, but they sounded realistic (like dogs barking off in the distance, people whispering outside your window...across the street, telephones ringing upstairs, people you know talking or saying things--like your name--sometimes to the point that you have to ask them if they called for you...and YES you do feel like an idiot, but if everyone knows your physical problems, due to the sleep disorders, they understand what it going on, and can laugh with you when it happens--EVEN the scary ones).

Sleep paralysis happens to be when your body tries to wake up, but it doesn't quite get there. hence you end up in a state were you are both awake and asleep at the same time (dreaming to be accurate). These events have a tendency to be a bit like the hypnagogic hallucinations, in that they can seem real, since you are half-awake. History has a great many examples of SP--the ones that don't seem that scary, like visiting angels. To those that can create bone-chilling "ghost stories", like demons and succubi. There is a very famous painting of a "breath-stealing" demon, depicting a SP event (many people did in fact DIE in their sleep from "lack of breathing", this is where SP fiction AND the reality of many of the SP sufferers having severe sleep apnea--something fully unknown in that day and age--were not taken into account, and instead it was a demon! Many people that DO have sleep paralysis events have dreams and dream like events that are close to and resemble each other, so there must be a basic psychological connection in the formation of many of these dreams--even space alien abductions seem to have this same thing in common...

So when a big SP or hypnagogic hallucination comes along, and just by chance it happens to mix with each either (if you suffer both), you can get some truly panic inducing events (go look these up, if you don't understand why they could be so panic inducing--you'll understand pretty quick why they SUCK; luckily, as I've gotten older my mind has created two ways to deal with sleep paralysis events; the first it created, and I don't know how to be honest, is that I realize in these "half-dreams" that if I relax I will gain all of my abilities back...sure enough it works every time, but it can be VERY hard to do this when you have a pure-evil, shadow of fear standing 10 feat from you; then lately...and I think this happened literally due to the shear volume and amount of SP events I've had...I can basically FORCE myself to move again through willpower alone, allowing me to wake up as well--doing this actually feels "odd", it feels uncomfortable, like you are "going against the grain" and then suddenly breaking through a wall that wasn't allowing you to do what you wanted; so I imagine this "ability" forcefully allows me to make my body stop it's "protective" mode that it is in as you sleep and it is ALSO what causes the "paralysis" in all sleep paralysis vents...it is just your body doing what it should)...

Also, from what I've noticed, it seems to me that almost all hallucinations at some level are directly linked with whatever in the mind allows us to dream or create very vivid "imaginations". Both my sleep paralysis events AND especially my hypnagogic hallucinations, accompanied by the fact that I have indeed ran into "run of the mill" hallucinations (caused by adverse effects from medical prescriptions in the past), they ALL seem to be essentially linked together from what I noticed. I'd have to look around and see if there are others that have as many vantage points as I do, and also agree that they seem linked.

Throughout history people have seen these two aspects as something they absolutely are not OR not even close too! Yet FAR too many people don't ask the absolutely obvious question that they ALWAYS should have! Why, do ghost, aliens, demons, angels, you name it, show up at NIGHT (or for those that have odd sleep schedules: when you are TIRED or about to SLEEP--or just have...)?!? The answer should, indeed, be obvious... All of these things have to do WITH our sleep or something with our ability TO sleep (you don't necessarily need to be asleep or need to have just woken up for this stuff to happen to you; my narcolepsy shows this is absolutely true--as I can get hypnagogic hallucinations at ANY time of the day, sometimes without warning). The creatures and gods we have created do indeed exist, but they are located at the border between where our brain can see clearly and when our brain could use some rest--then we all live in our dreams.

So, be careful about how much stock you put into anything you believe is true, especially because you "believe" you have witnessed or experienced something magnificent... Believe it or not, seeing is NOT believing! Science always had the right idea, you MUST allow others to confirm what you found, and if they cannot find it--no matter even IF you "found it"--you might need to be able to accept the harsh reality that somehow you didn't see or experience what you thought you did (but, it can still be amazing)...
