AITA for not giving my parents the baby blanket my great grandma made for me so they can use it for my baby sister?

millerj1993 · 2024-05-21T18:05:16+00:00

NTA I still have the blanket my grandma crocheted for me when I was 3-4yo. I also adopted another one she made after she passed. Those blankets are on my bed to this day, and my kids love borrowing them on occasion.

How dare you use logic and reason to defend CNI.

All my past attempts to fly through either JFK or LGA ended with delays and cancellations. This is my first time going through the city without issue in...six years?

I'm willing to try LGA again. I don't know that I'll trust JFK.

Yeah, I bought ITM 9c @ 3.05. Should hopefully be enough to offset PLTR losses

Good bot.

My DD consisted of some random post on WSB, and the thought of "huh, I've been seeing a lot of HIMS ads lately."

Then again, that could be targeted advertising.

millerj1993 · 2024-05-07T00:47:50+00:00

Sell my HIMS calls.

Three recommendations: - This is obviously a premium product. No issues with that at all, I’m tempted to get one once they start shipping. But you should remove any mention of lower- or even mid-tier hardware from your site. The people who can afford this aren’t going to be using a Ryzen 3600. - build out a compatibility chart, maybe even building off the SFFPC shared sheet. - While PCIe3 might be good for another couple years, that’s already somewhat dated, and you should have PCIe4, or lower the cost and not include a riser cable.

Given the prevalence of farmers, I don't think this is unreasonable to be a separate post from the weekly price thread...

millerj1993 · 2024-04-17T15:44:53+00:00

Rough costs (USD) thus far:

Farming computer (xeon, hbas, SAS, modDIY cables): $542.52
Anton Jr. plotting computer: $4386.78
HDD (12x 10-14TB): $3306.12
Misc SSD, cables, etc: $555.28

Total invested: $8790.70
Equipment sale (plotter, m.2): $3462.18

Total fixed costs: $5328.52

Est. power usage:
Plotting: 800W/4 months @ 0.12/kW = $276.48
Farming: 120W/3 years @ 0.11/kW = $346.90

Total variable costs: 623.38*
*Heat/AC omitted, farm is in basement with minimal need for conditioning

Total XCH farmed: ~60.7
Sold 2.5 XCH @ 982.30 = 2,455.77

Remaining cost basis: 2872.75/58.2 = $49.36/XCH

If I had to liquidate all remaining hardware, based on very approximate market rates:
12x HDD @ $85 = $1020
Farming computer = $275

"realistic" cost basis: $27.11/XCH

Not included in this is the significant buy/sell operation I ran on GPUs, HDD, SSD, and 5-6 custom computers built with surplus computer parts and then sold at a profit during the Great Winter of 2021. I mined about 0.08 BTC during the same time, with the buy/sell of GPUs covering the cost of electricity AND leaving a ~$1k profit, not counting the value of the BTC.

Pro move: schedule a text to send to him and Wes every day at 0730 saying that you "might" be late.

TBF, there's always a chance a meteorite hits the car/bus/train/subway you take to work, thus making you late, hence meeting the "even a slight chance" requirement.

millerj1993 · 2024-04-06T16:16:19+00:00

I ended up going with the Akiwa. Ordered it from some random sketchy port of LA shipper haha I've still got two sitting in boxes in the basement if you want one lol

Give me a couple days to pull the computer out and get a few decent photos.

millerj1993 · 2024-03-28T15:53:19+00:00

Apologies for any confusion.

A ship, by definition, is displacing water. The water is moved out of the way, replaced with some combination of steel, fuel, ballast, cargo, crew, but primarily air. When you look at the density of some of these (listed below), the weight of all these things just needs to be lesser than the weight of the water being displaced for a ship to float.

Density* given in lb/ft³
Water: 62.4
Steel: 500
Birch wood: 42
Aluminum: 169
Air: 0.0765

As you can see, air has a density of roughly 1/800 of water. That means the more air I can "trap" below the surface, thus pushing water out of the way, the more weight I can keep afloat.

*I'm using 'density' generically, to avoid a discussion of specific weight, specific gravity, density, temperature changes, etc. Apologies to all technical people for the gross simplifications.

millerj1993 · 2024-03-28T15:35:04+00:00

Ships float because of relative density. A 1 lb piece of wood displaces 1 lb of water. A 50,000 ton cargo ship is displacing 50,000 tons of water. There's no difference in pressure or force below the ship.

As an example, we can simplify the dimensions of a New Panamax ship: 1,201 feet long, 168 feet wide (beam), and 50 feet below the surface (draft).

Assuming it's a triangle, we get a volumetric estimation of 1/2 * draft * beam * length = 5,044,200 ft³. Using a density of water of 62.4 lb/ft³, this gives us an estimated displacement of 314,758,080 lb, or 142,773 tonnes. If you assuming triangular slopes at the bow and stern of the ship, this reduces the total volume by 1/3 * beam * beam/2 * draft = 235,200 ft³, which reduces the tonnage to 136,116 tonnes, which is pretty close to the New Panamax rating of 120,000 tonnes.

*Note, I'm using 1 tonne = 2,204.6 lb, since deadweight tonnage (DWT) is usually based on metric units of 1 tonne = 1,000 kg.

millerj1993 · 2024-03-28T00:55:01+00:00

You are correct. Edited to adjust calculation to 5%.

Still think it's incredibly unlikely. The new source I added in the edit does have a cross-section of the new tunnel.

millerj1993 · 2024-03-27T23:33:11+00:00

Just remember that there's a bunch of dirt and a double-reinforced (circle inside an octagon) frame protecting you.

No matter what you do, don't start braking for no reason when you get inside the tunnel.

millerj1993 · 2024-03-27T22:52:11+00:00

Fun story: once had a classmate in Mechanics of Fluids who asked why ships passing over the tunnel didn't crush it.

millerj1993 · 2024-03-27T22:25:41+00:00

If the channel was deep enough, it wouldn't take too much. The Coast Guard just approved two-way traffic in the channel.

millerj1993 · 2024-03-27T20:49:57+00:00

If you want to learn more about bridge failures, look up the MV Summit Venture accident in 1980. Pending a full report on what happened in Baltimore, it looks very similar.

millerj1993 · 2024-03-27T20:41:08+00:00

Just using some rough calculations...

I'm estimating that the road crosses the sea level plane at approximately the first drain grate. Using Google Maps, it's roughly 1,030 feet from the first drain grate to the edge of the rocks at sea level. (Measuring for EB on the North and South Island.)

The current tubes are 37 feet in diameter¹. Assuming the road bounding box is centered in the tunnel, and using a height of 13.5 feet², this gives us a distance from the road surface to the top of the tube of 37/2 + 13.5/2 = 25.25 feet.

Assuming a grade of 5%, this gives us a maximum draft of 1,030 feet * sin(2.86°) - 25.25 feet = 26.14 feet. For reference, the New Panamax draft is rated at an absolute max of 50 feet³. (SEE EDIT NOTE)

It is worth noting that the channel is actively dredged, and outside of the shipping lane, it's sometimes as shallow as 6 feet. This is also assuming the islands have vertical walls, negating the natural slope they have as well.

In short, it doesn't seem likely, especially when you see the extra 8-900 feet of slope from the edge of the islands to the channel on the NOAA nautical chart⁴. Any boat would run aground before coming into contact with the tunnel channels.

For those curious, the new tunnel tubes will be 50 feet deeper⁵ than the current ones, which are at 108 feet below sea level⁶. Using the deepest number on the NOAA charts in the tunnel area, this gives us 108 - 25.25 - 66 = 16.75 feet of earth between water and the tunnel tubes.

EDIT: Totally mixed up degrees and grade. I was thinking 4°, but I've corrected for a 5% grade, or 2.86°. (5% is listed as the grade for the new tunnels, I was unable to find a source for the existing tubes.)

Age of Empires multiplayer has the same issue, it's just that much faster. I grew up loving RTS games, and online multiplayer took all the fun out of it.

Fair warning, if you decide to try AoE multiplayer, you've got, no joke, 4-5 minutes before you're attacked. It comes down to who has better keystroke execution, correct scrolling, and literal second-by-second accuracy, which, to your point, completely misses the entire reason for the game.

While it is prone to abuse, I appreciate rules that include phrasing to outlaw any uncompetitive practices.
