Rebuilding the Oroville Dam Spillway | Practical Engineering

newtboy says...

*quality engineering, sadly only required because the original contractors cut corners and no regulators caught it before it failed. IMO, the companies that built it should be paying that $1 billion price tag. They’re the ones who used low quality concrete, left out literally tons of rebar, and decided a soft dirt emergency spillway on an earthen dam was good enough.

This is why we need a $3 trillion infrastructure bill. Really, we likely need ten times that. We haven’t invested in infrastructure for decades.
Had there been regular real inspections they likely would have noticed the problem when repairs only cost $100 million. There are literally thousands of dams in America with similar, or worse issues, and no money to even properly inspect them, much less fix them before they fail. Waiting for them to fail costs at least 10 times what pre-failure repairs cost, but we only care after they fail.

Thanks Manchin, our nation is crumbling thanks to you joining the obstructionist Republican Party, someone needs to burn his yacht with his family on board while he watches, then burn him in his mansion and distribute his hundreds of millions back to the state he stole it from.
Edit: Btw- Goldman Sacks has revised their 2022 estimate for gdp based on Manchin killing the infrastructure bill from over 3% to barely 2%. >$200 BILLION just gone with his vote against America. This as Manchin says “the Democrats aught to push me into the Republican Party”, but you’re already there, Joe. They aught to deny you funding and primary you, but not hand another seat to Republicans as you suggest, traitor. They really aught to strip you of all assignments, all funding, all security, and start broadcasting your location 24/7 until you are gone. If you ask me, they aught to drop you feet first in a slow meat grinder and make a day of it, televised. Then they aught to forced feed you to your family before taking every dime they have and denying them any assistance from anywhere. That’s what aught to happen to skidmarks like you.

LMFAHS!!
That wall that cost billions, stole private property, broke dozens of environmental laws, fell in many many places, can be thwarted easily with a ladder, rope, angle grinder, truck, or climbing skills and hasn’t slowed illegal entries one whit? That wall? Ha! You’re funny.
Remaining in Mexico (as major targets for organized crime) during the lengthy asylum application (sometimes for years)….maybe you’re too ignorant to know that never stopped.
Regaining an energy independence that never existed? Um….yeah. We had a minor surplus last year, not because of more production but because the Trump recession and the Trump pandemic lowered demand to the point where oil producers were giving oil away for free. Yes, in summer we exported some oil, but never as much as we import in winter. This is another Trump lie you repeat without a thought and certainly without verification…because you still believe what he tells you despite everything he’s ever said being a blatant lie for his entire lifetime, multiple fraud convictions, being banned from charities because he stole from veterans and children,….the list of his crimes of moral turpitude is never ending.

Goo start….nice unintentional pun. (Sad you can’t help but fail at English even as you correct your original hilarious mistake).

Increasing our oil output is a goo start, but a god awful plan. It’s actually a non starter, Biden pushed oil companies to increase production for months, but they preferred high prices and high profits. They have millions of acres with drilling rights they don’t want to use because the profit margin is 5% lower and blame the fed for not giving them access to the last pristine national forests and reserves….so again I’ll ask you, nationalize oil? If you want to blame the government, they should have control, otherwise you’re just a whining baby crying over spilled milk and blaming the wrong people.

Requiring better fuel economy from vehicles and industry, phasing in electric vehicles and more green electricity production are actually GOOD starts, and what Biden is moving towards despite total opposition from Republicans on ANYTHING. That’s how you get actual energy independence….the only way in the long term.

Returning to Trumps policies of building the wall, Remaining in Mexico and regaining our energy independence is a goo start.

‘This is not a zoo’: Biden administration blocks filming

newtboy says...

Wait....I drink a line by the gallon? Probably better if you don't try to use metaphors, buddy. You don't know how.

Trump's plan? Working? Which one?
His plan to start a depression and epidemic concurrently, making America less appealing?
Or his plan to deny entry to even unaccompanied minors, leaving them alone in Mexico, ripe for abuse with no protections?

You know Biden is continuing the rest of the Trump plan so far, only letting unaccompanied minors across into refugee camps....like Trump did until he caught flack for caging them and denying it....don't you? Probably not. OANN isn't telling you that, and you abdicated your ability to think for yourself long ago.
No one opened the border. You're being lied to again by the same asshats that convinced you of the election fraud fraud. Why do you keep begging them to mislead you? Why do you so enjoy being a misinformed idiot, Bob?

It's odd you aren't complaining about caging them in over crowded camps (which I see as an abject failure by Biden's administration)...perhaps you can foresee the ridicule you might get for complaining about the same thing you defended Trump over?

If Trump's failed fence worked at all, there wouldn't be any making it....but it doesn't work at all....it's usually less secure than what it replaced. It can be cut through in minutes with battery operated grinders and takes days to repair. Some fell down from wind. Almost any section can be pulled down with a car and a chain in seconds. He removed imperfect barriers in favor of useless fencing, making it easy to drive truckloads of anything across the border at will. Thanks Trump....great plan.

I would admit, Biden isn't doing better at preparing for the numbers of refugee children, and he hasn't changed policy much beyond not abandoning children to the cartel sex trade, but treating refugee children like refugee children and not like criminal lowlifes is a step in the right direction. Now we need the infrastructure to handle them. For the money wasted on Trump's legacy fence we could have built it already and could have a functioning immigration system, but Trump had to have that fence....that Mexico didn't pay for.

Note, the main reason people are coming is narco terrorism, created by the war on drugs and made exponentially worse when Trump cut international funding to fight it when his ass wasn't properly kissed by other country's leaders. End the failed war on drugs and use that money to fight organised crime in central America and the flood will be a trickle overnight. Of course, the right has no interest in that, and ignore the evidence of how well decriminalization works.

🤦‍♂️

Trumps plan was working.
Biden plan was come on in and open the flood gates. No planning on trying to figure out how many people are out there ready to storm the gates..... He just open the doors and got a stampede.

kinda like Thanksgiving

Terrible flaw in expensive crowdfunded padlock

bitterbug says...

The *average* padlock isn't. But there are very high quality locks in the 80 dollar plus range that protect against people with tools.
They may not stop someone from getting past them in an isolated spot, but they're hardened enough that a person with a grinder will need 15 or more minutes ... and with that kind of noise and risk of attention it's not worth it.
So buddy goes and knocks off your master lock with a hammer

AeroMechanical said:

Meh, padlocks are not for securing valuable property or for securing property against someone with any sort of tools at all. They are for preventing opportunistic theft. 30 seconds to defeat the lock is plenty long enough for that. Of course, that is a pretty stupid design, so good video nonetheless. If I owned one already, a little solder or permanent loctite on the inner screws would probably do the trick.

Mostly though, The lock company lost me at $100 for the lock. A traditional dial is not *that* hard to work and I'd be worried about false negatives and dead batteries even with a high-quality finger print reader. Just buy a $10 padlock at the hardware store to lock up your garbage cans, or proper u-lock or quality cable to lock up your $600 bicycle (ie, something that will require 15 minutes to defeat).

Corn On The Drill Challenge Gone Wrong

AeroMechanical says...

When did this become a "challenge?" Are we curing Lou Gehrig's Disease or something?

Hair Cut with a Weedwacker Challenge? Nail Trimming with a Bench Grinder challenge? I can come up with more if we need to cure some more diseases.

If Meat Eaters Acted Like Vegans

transmorpher says...

I used to be a vegetarian, longer than I have been vegan, for nearly 10 years, because I was under the wrong impression of needing protein from eggs, milk and cheese to live healthy.

I came to the conclusion that as a vegetarian I'm still contributing to needless animal suffering, because it turns out that the dairy and egg industries are the two cruelest businesses out of all of them, and even then they are closely tied to meat production.

Male chicks being thrown by the bucket load into blenders and grinders because they are no use. The egg laying hens in the dark to save electricity costs, inside cages where they cannot move, or have fencing for a floor. Wings clipped, beaks chopped or burnt off. When they stop laying or collapse from exhaustion they get killed for meat anyway.

It's the same for the dairy industry, horns cut or burnt off, if they're born male they get turned into veal. Female cows constantly impregnanted to force milk production until they stop or collapse, then get turned into meat anyway.


I don't think I've called anyone a murderer, torturer or rapist. But people seem to love telling me that I do.

If anything I would be calling you an accomplice, since I doubt you are the one doing it. I wouldn't be doing it to make myself feel better, I'd be doing it because it's true. You're paying someone else to torture, and kill totally unnecessarily - There is no reason to eat any animal product for the majority of people on this planet.

I've put this out there in the past, and it still counts - if anyone can give me one good logical reason to eat any animal product, I'll eat a raw bloody steak on youtube.

Payback said:

That's pretty selfish and indicative of the main problem normal people have with vegans. You pontificate about your lifestyle, and how much better you are, and how we're murderers, and all we see is the extreme narcissism.

Vegetarians go plant-based for health, and/or for empathic reasons, whereas vegans are merely making a self-aggrandizing political statement.

What if the World went Vegetarian?

transmorpher says...

Go vegan instead https://www.youtube.com/watch?v=Y9nNa81dSoY
IT'S EASY! Just take a few weeks to get informed, don't jump into it. Read the books suggested below.

Vegetarian is a nice thing to do, but it should be really be only a stepping stone on your path to fully plant based diet. Plant foods are hearty delicious foods like pizza, burgers, lentil shepherds pies, pastas. You just swap out one or two ingredients that are from an animal origin, add more spices/herbs and you have a filling & healthy meal. You can stuff your face, and lose weight, lose the type 2 diabetes and heart disease as well. It's win win.

What many vegetarians don't know is that the milk and dairy industries are often more cruel, than farms that just use animals for meat, and often they are also intertwined. For example, for a cow to produce milk, it must be pregnant. Where do all of the offspring go? Veal if they are male. Or they become milking cows if they are female - destined to be constantly impregnated for their short 4-5 year lives until they die of exhaustion, or can no longer produce milk from exhaustion, and turned then eventually into meat. There are plenty of videos online where a cow gives birth and the calf is dragged away by it's hind legs. They both cry out to each other for days until they're voices give out.
Also cows milk GIVES people osteoporosis because it siphons out calcium from your bones, since it is so acidic. If you measure the amount of calcium in a glass of milk, let someone drink it, and then measure the calcium in their urine, then the urine contains more calcium than what went in. And it's being leeched from the bones.

It's a similar story for chickens. Male chicks get thrown into a grinder ALIVE. Because they're no use if they can't lay eggs.


The toxic waste produced the by milk and egg industries (animal poo etc) destroys environments.

The antibiotics used to keep all of those animals of course ends up in the environment and it will eventually make a super bug which medicine cannot kill.

The job loss portion seems silly, since anyone farming animals is capable of farming plants like rice, potatoes, wheat and grains etc. Those are some seriously nutrient and energy dense foods, and very efficiently produced, and very healthy. Carbs have just gotten a bad reputation thanks the Atkins people. And well we know that Atkins died of a heart attack, he had a history of heart attacks infact. He died overweight.

It is much easier just to go "cold turkey" for 3 or 4 weeks, and become completely plant based since it means your taste buds will adjust and you'll never crave animal products again. Everyone wins, the planet, your health both physical and mental, and of course the animals.

There are plenty off great books with recipes that are familiar and hearty that can help people get started, it's easier than you think. Books such as:
The Starch Solution, Dr. John McDougall.
Negative Calorie Effect, Dr Neal Barnard.
Power Foods for the Brain, Dr Neal Barnard.
Engine #2 Diet, Rip Esselstyn.

Cat has impressive velociraptor purr

Engels says...

Our girl kitty has a similar purr. One of her nicknames is 'squawkles', cuz it sort of sounds like a bird sqawk put through a purr grinder.

World's Fastest Butcher

Hexagon cake knife? Hexagon cake knife. Hexagon cake knife!

Can't be much harder than my lawnmower blade, which seems to have been expertly designed to make sharpening large portions of it it on a bench grinder or even a whetstone impossible.

Extreme reduction gearing - 1:11,373,076

iaui says...

Ahhh, but that's part of the beauty of the thing. The grinder gears, as they're called, are just one outer ring of n gears and one inner ring of n-1 gears. The pressure of the planetary gear causes rotation of the grinder gear by meshing one notch over each full rotation. It's an incredible increasing of the gear ratio. I believe in the video he says 1 : 17,000.

zor said:

I like this but I deduct points because the planetary helical gears aren't even meshing teeth with the inside of the large gears. They're just rolling along...

War Thunder - Victory is Ours - Most Epic Game Trailer Ever

radx says...

And to expend on it for a bit, in order for them to use the iconic Tiger, a scenario with plenty of entrenched infantry is much more appropriate than any mobility-based warfare. Great tool to force a breakthrough, even greater tool to prevent a breakthrough.

For instance, the handful of combat ready Tigers deployed with the 502nd during the battles around Lake Ladoga in '43 were used almost exlusively in two roles: either to strengthen entrenched friendly infantry against attacking armor or to throw Soviet infantry out of trenches seized in previous assaults.

The entire area of operations around Leningrad, including the supply lines around Lake Ladoga, was one big trench warfare, with massive use of artillery. Armoured spearheads only enabled the following infantry to advance from one line of trenches to the next. Extensive breakthroughs and large scale encirclements were only possible in the steppes further south. The marshes and dense forests up north reduced everything to a meat grinder.

Awesome, Unique Design Makes this Lock Un-Pickable

MilkmanDan says...

Engineering a way to prevent picking (or at least make it VERY hard -- never say never) is cool. But, the fact that it remains weak against all the other ways to circumvent a lock (grinder, bolt cutter, hacksaw, hammer, whatever) would mean that I wouldn't want to pay very much for one even though the design is impressive.

I figure that 95%+ of the purpose of a lock is to prevent "casual" theft/entry. If someone *really* wants in there, it doesn't much matter how good your lock is.

Best of Hitchslap: Part One

VoodooV says...

your inability to move past a comment I made MONTHS ago is quite amusing. This is at least the 2nd time you've gotten really butthurt about that.

Must have really struck close to home.

Once again you show you don't know how things work. No one ever claimed love existed as a physical thing. Love is merely the description we have assigned to humans who exhibit a certain behavior towards other humans. No one ever claimed it was some sort of tangible...thing

Try again chum. Maybe after your next grinder hookup and you've had a chance to release your pent up desires and you're less cranky

lantern53 said:

There is no love, either. No one can prove it exists.

Since I'm commenting on this post, I secretly want to be an atheist, right Voodoo?
