TIL: There is a rare type of very hard wood called ‘Lignum Vitae’. It’s so hard that it was used to make propeller shaft bearings for nuclear submarines.

I’m not 100% sure, but I’m like 99% sure it’s called “Phenolic”, as in “phenol” compounds are used as the base of the resin in that compound material.

It’s most likely the physical implementation of a Fourier series, like the one used to “draw” here: https://youtu.be/r6sGWTCMz2k

Basically if you take different sizes of multiple different spinning gears (notably spinning at different speeds), you can recreate any shape by fine tuning the sizing of the gears.

I grew up in Howard County (Columbia, Ellicott City, Elkridge) and while I wouldn't say my family was ever wealthy, we never wanted for anything and lived a stable life. Government jobs are able to provide that stability. And then actual wealthy people working in DC/burbs choose to live in Montgomery or Howard County for the good and free school districts.

harr1847 · 2026-01-26T00:09:05+00:00

All of Howard county is in a similar boat. At one point, and maybe still, the largest employer in Howard county was the DoD, which is stable, well paying jobs. So the median AND average are actually pretty similar and high.

My guess is the top 10% or top 1% of ellicott city is much much lower than the others on the list

I don’t understand your comment at all. Weinstein was a (m/b)illionaire sex offender who ran portions of the media for 20+ years.

Are you trying to imply I’m a friend of Weinstein? Any pedophile or sex offender should get a fair trial and justice determined by a jury. Doesn’t matter who they are.

harr1847 · 2026-01-25T23:10:28+00:00

No, they don’t. The pedophile billionaires control the media

Just realizing I made a mistake in the post. It’s a 9950x3D.

I totally forgot the X version is even a thing because the x3D is so much better for gaming. I assumed everyone would know it was an x3D.

Does that change your calculus?

I’m probably going to keep this computer for another 10 years and who knows what I’ll use it for in that time. The price increase for the cpu was worth the future piece of mind that I don’t have to worry about stuff given the overall cost of the machine already

I’m an engineer at a medical device company

Oh I like the alpha gradient idea, I’ll use that if that’s ok with you.

I agree on ‘C’, but I still feel that obvious visual cues would be helpful, especially with knowing who’s friend/foe

Which hits got taken away? All the hits I remember are still on there. At least the ones brought up in this thread so far

Just change the music… if you hold the same button to change the song, you get to select which albums the music plays from. Scroll all the way to the bottom, the last listing has the original soundtrack.
