Shit that annoys you

Why does my printer make 5 minutes of weird mechanical noises before it finally decides to print? Damn thing sounds like an MRI. For that matter why does an MRI make all those weird noises? Makes no sense to me. I guess I shouldn't complain about the printer since it's replacing one that refused to make any noises, or print.

Agreed on the MRI. I had one recently and was like WTF? Umpteen years of high tech and they can't make a machine that doesn't sound like it's gonna blow up.

Hope you remembered to remove the piercings from your dick.

Hey, if magnets be wanting' to get it on, best be doin it on they're own damn time.

There are two groups of noises you hear. The constant pumping/whooshing is the compressor keeping the liquid helium cold which enables the superconducting main magnet to work. This is always on (hopefully).

The other noises are the loud buzzing sounds that only happen during the scan itself. These come from the extremely rapid pulsing of electricity in the wires inside the secondary magnet coils. There are secondary coils inside the main gantry body, and smaller ones they place on top of the anatomy of interest. The secondary coils make radiofrequency waves in order to induce changes that can be measured.

Essentially, the main magnet lines all the spins of every hydrogen atom in your body up in one direction, then the secondary magnets in the coils turn on and shift the spins a bit. We can measure how long it takes to get the spins lined up to the original position when the secondary is off, and mapping that data becomes the image as different tissue types have different responses. The secondary gets pulsed rapidly with a lot of power and shakes around making noise. Lots of subtle changes in how and where they are pulsed lead to the various buzzes.

^^ Cool. How do you know this? Are you a tech or did you just sleep at a Holiday Inn Express last night?

I'm surprised that doesn't hurt more.

[Vt-Freeheel]

Gotta align those atoms if we're ever going to get the transporter working.

And here I thought I wasn’t going to learn anything good today.

It can heat people up even if it doesn’t hurt.

Also have to make sure there are no saline filled lines coiled in the scanner. Remember the rules of thumb for electromagnets in high school physics? You can create a lot of heat by turning a electrolyte filled coil into an electromagnet.

Riding in to work today a lady was jogging against traffic in the bike lane with a perfectly good sidewalk ten feet to her left. For the love of God, why? It's a busy street that thankfully had a break in traffic at the time. She clearly had zero intention of yielding to me and I had to swing into the lane to not run her over. Could have been sketchy as hell if there were cars, as there normally is.

This drives me nuts too! I've thought of coming to a stop right in front of one of these people and asking them not to run in traffic. Gotta wait until it happens again and then pretend to be cheery when I ask.

I am sure they had right of way...

In CA pedestrians in the bike lane must walk/run against traffic and yield to bikes when possible. But they do things weird in Utah.

In Sacramento--walkers in McKinley park like to clog up the dirt and fine stone running path, even though it is a few feet from a sidewalk. Guess they like the softer surface. BUT on the American River Bike trail, the walkers and runners like to go on the paved bike trail (usually with their backs to traffic) when there's an excellent pedestrian path right next to the pavement. The moral--people will naturally do whatever is most inconvenient for others, not because they are evil but as a desperate scream of "I am here" into the meaningless void of the multiverse.

You 'are sure' a pedestrian prancing in traffic has the right of way? they can run wherever they want on a roadway?

Just to be clear, this is not a recreational bike path we are talking, it's a traffic lane on a street. By law in Utah joggers have to use a sidewalk. I don't care if joggers use the road if there's no sidewalk.

Even if the jogger is breaking the law, pedestrians always have the right of way in that you're not allowed to hit them and claim "but they were in the road!" So if "right of way" here is being used as "not breaking any laws" then they might not have it, but if "right of way" here is being used as "you must yield to them", then yes, they have the right of way.

I love you Danno, don't get me wrong, but do I really need to clarify this?

[Brock Landers]

I’m anti-jogger myself. And biker.

[Supermoon]

not because they are evil but because most people are just oblivious to their surroundings.

we recently looked at airbnb & vrbo for an OR beach weekend spot &, fuck me, the fees were as much as the published rates!

ie, the "rate" portion for 4 nights was half of the total amount once you got it calc'ed out

publish the fucking rate that covers costs as a single goddam number, and you will end up with customers who don't feel like they are wasting their time looking at properties

Hah, just did that myself. North of $500 for two nights at a place with a listed rate of $160/night.
