@Cowboyincognit0 @chris_borns They're nearly all gasoline. The EV ones may never materialize.

$160k per truck they took the Workhorse entry design and Oshkosh is building it. So what did we get?
• Bad aero
• Back door they aren't allowed to use for entry
• Build slapped and glue together by a drunk robot.
• Aluminum construction
• Improved fuctionality
The thing is crazy expensive for what it is.

@Katrina_Lexxa @ashleyschendel My back definitely felt better when I switched to the front pocket!
English

@ashleyschendel I never did understand wallets anyway.
How can one sit comfortably with that thick thing in their back pocket.
English

Very rarely will you need to buy your husband a new wallet, but when that day comes, it is somehow a major household decision and you cannot screw it up.
Men will carry the same wallet for 20 years with the corners falling apart and still say it’s fine.
So this is not the moment for creativity. Slim, durable, leather if he’s a leather guy, metal if he already likes that kind of thing.
Do not surprise a man with a weird wallet.

@OleBeeM @ashleyschendel How do you stay under 10% utilization with only one card? Just a huge credit line? I have to swap between cards constantly.
English

@ashleyschendel Wallets are done.
1 credit card in your pocket only.

@VargasKevi23363 I had a kid tap my back bumper in traffic, he pulled over with me. His licence plate screws punched holes in my bumper, but really not that bad. Sometimes it's best to just let it slide. He could have fled.

Encontré una nota debajo del limpiaparabrisas cuando salí del supermercado.
Pensé que era publicidad. Casi la boto sin abrirla.
La abrí.
Decía: "Le rayé el carro sin querer al abrir mi puerta. Está en el lado del conductor. Lo siento mucho. Si quiere hablar, aquí está mi número."
Fui al lado del conductor.
Había un rayón. No enorme, pero tampoco pequeño. De esos que uno ve y suspira.
Miré el número. Miré el rayón. Pensé en todo el proceso. El seguro. Las llamadas. El taller. El tiempo.
Llamé.
Contestó una voz joven. Muy joven.
Le pregunté cuántos años tenía.
"Diecinueve", dijo. "Es mi primer carro. Llevo dos semanas con él. Lo siento mucho, de verdad. Puedo pagar el arreglo aunque me tarde un poco."
Silencio corto.
"¿Dejaste la nota tú solo o alguien te dijo que lo hicieras?"
Dudó un segundo.
"Yo solo. Mi papá me dijo que si alguna vez pasaba algo así simplemente me fuera. Pero no me pareció bien."
Miré el rayón otra vez.
"Olvídalo", le dije. "Ya tenía otros."
No era del todo verdad.
Pero él tomó la decisión correcta solo, a los diecinueve años, yendo en contra del consejo de su papá.
Eso valía más que el rayón.

@Computim @davepl1968 Yeah was thinking that but the keying is off. M12 C code seems most similar. Maybe a proprietary keying.
English

@davepl1968 Looks like a 4 pin M12 Male. We used to have them on PLCs and various industrial devices at the plant I worked for. Not 100% sure based off the dimensions.
English

Can anyone ID this connector?
It looks like a 4-pin male mini-XLR, but it isn't one.
They're used in DEC hard drive sequence cables, where the initial power draw was so high that you can only power one up at a time, so they sequence through special in and out ports on each drive, connected by these cables.
I have a couple of DEC 70-19690 cables with these ends, and I could sacrifice them, but I'd much rather find a source for the actual plug/connector... if I could ID it!

@chachabenny42 @centristpeater Doing some reading about the place I saw the sign, I guess it's for the birds. The birds will eat the ticks, so they cannot spray/kill off the ticks.
English

@LarsBolduc @centristpeater for what reason? genuinely asking
English

@NefflynB That would happen to me, It was from cleaning my glasses with my shirt. I have stopped since due to this wear and tear.

@aakashgupta Wait, but bicycles stay upright without a driver to output controlling responses.
English

The physics of why bicycles stay upright is one of the most embarrassing unsolved problems in classical mechanics.
For 150 years, textbooks said gyroscopic precession from the spinning wheels kept you balanced. In 2011, a team at Cornell and Delft built a bicycle with counter-rotating wheels that canceled all gyroscopic effects. Zero precession. The bike still stayed upright.
Then they said it was trail, the geometric offset where the front wheel touches the ground behind the steering axis. The Cornell team built a bike with zero trail. Still stable.
They published in Science. The title was basically "we've been teaching this wrong for a century." The actual mechanism is a feedback loop between your lean angle and the steering geometry. When you start to fall left, the front wheel turns left, which pushes the contact patch under your center of mass. You correct without thinking. Your vestibular system and motor cortex run a continuous control loop at roughly 5-10 corrections per second.
The reason you fall when you stop is that the correction loop needs forward velocity to function. Below about 5 mph, the geometry can't steer fast enough to catch your lean. Einstein was right about the keep-moving part. He just got the mechanism backward. Balance on a bicycle has almost nothing to do with momentum. It's a real-time control system that happens to require motion as an input.
The cyclist in this video doing a track stand is running that control loop manually at near-zero velocity. That's harder than riding at full speed. The scooter passengers don't need any of this. Three wheels. Static stability. Physics solved that one a long time ago.

Life is like riding a bicycle. To keep your balance, you must keep moving. —Albert Einstein

@zapatas_mom Not owning the roof, not owning the ground, not owning the bushes. Basically the same as renting, but quadruple the price. Who would want a condo?!?

@K21A27A Gorgeous big body. Old big body cars sit on the road like nothing else, commanding.
English

@laurenfbuf Just exudes style at every single angle, no matter where the eye lands.
English

@AutoPap I've seen enough videos of Ferraris burning to the ground. Gasoline is to be respected.

@Locus_Solus3303 One time I was at a brewery campus with lots of one type of tree. Apparently trees communicate with each other and can synchronize. All of them dropped their pollen within 10 minutes of each other. Just clouds of pollen coating a lot of people.
