Just a heads up, the whole “you don’t have to aim” is a complete myth. Shotgun spread is completely blown out of proportion. It’s somewhere around 0.5" to 1" per yard with barrel length, choke, and shot type affecting spread. Unless you’re insanely rich and live in a mansion, you’d be within 10 yards so you’d only get 5" to 10" of spread which really isn’t much especially since the pellets may not be evenly distributed within that diameter.

For anyone looking to buy a gun, educate yourself first to know what you’re getting into and go to the range consistently so you know how to use it. If you don’t do both of those, you’d be at risk of hurting yourself or someone else if ever you have to use it in a life or death situation.

There is a much cheaper way that doesn’t use hard drives. It uses magnetic tapes, LTO-9 tapes specifically.

Each LTO-9 tape cassette can hold up to 45TB of data (compression is used to store it on the raw 18TB).

An LTO-9 tape drive can cost $10,000. Assuming you get the full 45TB per tape, you’ll need 2223 LTO-9 tape cassettes to store 100PB. Assuming you buy in bulk, you can get each tape cassette for $150 which puts you at $333,450 for the tapes.

Since the tapes don’t use power when not in use, this concludes the total cost. None of this accounts for storing all 2223 tapes or maintenance to ensure data is still intact on them but this comes out to $343,450 in total to store 100PB using magnetic tapes. While the cost is much cheaper, it’s much harder to access the data as it’s not immediately available since you have to fish out the drive you need and plop it into the tape drive then wait for it to read.

Let’s assume you have all hard drives and in a setup with absolutely zero redundancy in case a drive fails.

We’re using the Seagate Exos X24 (24TB) drive which is roughly $700 each brand new.

You’ll need 4167 of them to store 100PB. Which puts you at $2,916,900 just for the drives.

Let’s assume you already have the enclosures, racks, and servers for a small datacenter ready to go.

A drive can use 4-9w of power when spinning so assuming all drives are active (to ensure quick data access and data repair) that’ll be roughly 27086w for all the drives at 6.5w per drive. Every month (30 days), that is 19502kWh of electricity used. 40 years is roughly 349,680 hours so that comes out to around 9,471,433kWh used.

Assuming you get some damn good electricity rates at $0.12USD per kWh, it’ll cost $1,136,572 to run just the drives.

So in total, assuming you already have a datacenter with the capacity to install all the drives that runs on absolutely zero power, you’ll spend roughly $4,053,472 over the course of 40 years.

I’ve a massive blob like this one time when the nozzle got clogged and the extruder created enough pressure to push the filament through the threads of the hotend block. It was on an Anet A8 and I ripped a lead off the thermistor trying to get the plastic off so I ended up replacing the entire hotend.

You can try to heat up the hotend to a fair bit under the melting point of the filament to where it’s soft and somewhat pliable but not runny or sticky and then trying to peel it off. Though you’d risk damaging any leads to the thermistor, heater, or your hands if you’re not careful.

Good luck on fixing the printer and getting back to printing again. 3D printing is a really time consuming hobby

What does being a person mean to you? Could a sufficiently advanced AI become a person and if so, at what point would it become a person that deserves to be treated the same a human? If a machine can be a person, would it be plausible for a person to become a machine? For example, with transhumanism being possible, would a human that has ship of theseus’d with machine components instead of biological components become a machine instead of a person?

I was born in the current millenia so I wasn’t around during the aerospace boom but it makes me kinda sad that looking back, there was so much innovation and hope for a future. I remember talking with some older people in how they thought we’d be living on the moon or Mars by now after seeing the Apollo missions and seeing commercial supersonic flight. I still remember going to the library and checking out books about how technology was developed and reading in awe about the insane engineering behind each thing.

It’s just sad that all of the potential and movement was just shutdown by politicians and the rich just so they could get that extra little bit more wealth and power year after year.

Don’t forget sexism too
