Advice on migrating current media library from standard shares to a single "data" share for Hardlinks (Atomic-Moves)

What's the best method for me to transfer my library and settings from binhex's "arr" apps with the old file handling method, to hotio's "arr" apps with hardlinks (Atomic-Moves)? From my knowledge, I'd move all the files with krusader/unbalance, import the libraries into the "aar" apps, and then copy the settings manually. Does this sound right?

2nd question- If I keep my music/audiobooks in the "hardlink" environment, will it cause me any issues since they get automatically handled by beets/mp3tag after download?

I've been running a 2nd download cache (HDD's) for my torrents and such, and then copy the files to my array. It's currently set up with "arr" apps -binhex). Following TRaSH's guide and Ibracorp's Video, I've setup my new "data" share and accompanying programs ("arr" apps -hotio).

What exactly does "relative to C-12" mean? A question regarding atomic weight.

So I'm trying to understand the definition of atomic weight (? a bit confused with the names as well). Here's what I understand so far:

- masses of atoms are cumbersome to express in kilograms, so scientists came up with a more simplified way of expressing them:

- by using the stable and abundant C-12 isotope, containing 12 nucleons, they defined the atomic mass unit as 1/12 of the atomic mass. Since the mass of the electrons is negligible, this essentially gives us an approximate mass of one nucleon (a proton or a neutron)

- by using C-12 as a baseline we can now define other isotopes' atom masses relative to C-12.

The thing I'm trying to understand is why other isotopes masses aren't integers like C-12. I thought the whole idea was to get integer numbers as an easy way of measuring atoms masses. My google searching found the following, which I'm struggling to understand:

- due to isotopes' different binding energies they all have different mass defects. The mass defect is defined as the sum of the components' masses minus the experimentally measured mass. I sort of get this, but:

- because the masses are relative to C-12 they will not be integers.

^ This is the thing I'm struggling with. Relative how?

So the C-12 experimentally measured mass / 12 equals 1 amu, meaning that the C-12 mass defect is "baked into" this unit. How do we determine the masses of other isotopes then, relative to C12?

Do we just experimentally measure the weight of the isotope atoms in kilograms, and then express them in amu? Is this what "relative to C-12" means?

Any insights are appreciated!

[Highschool: Atomic Weight] Relative Weight of Magnesium (Lab)

Can someone help me understand this please? I'm so lost. We were given questions after doing a lab on the relative weight of Mg.

We had to heat magnesium and expose it to oxygen every minute for 10 minutes until a reaction occurred. Here are the recorded masses:

reacted Mg = 0.077g, reacted O = 0.14g, MgO = 0.217g

Calculation #04: Ratio by weight of magnesium to oxygen = Mg/O *(literature value = 1.5)

0.077g/0.14g = 0.55

Questions

  1. What is the difference between an absolute weight and a relative weight? Use your experimental results as an example.
  2. Explain why the Mg/O ratio in calculation #4 can also represent the weight ratio per atom of Mg and O.

SILVER ATOMIC WEIGHT = 108

The number 108 has always been a highly revered number for thousands of years, coveted by many spiritual traditions and ascribed special significance in meditation and prayer. Considered to be the most auspicious number of all, 108 also happens to be the number of stitches on a baseball.

The wholeness of existence – Renowned mathematicians of Vedic culture viewed 108 as the number of the wholeness of existence. Astronomically, there are 27 constellations in our galaxy and each has 4 directions. 27 x 4 = 108. In other words, the number 108 covers the whole galaxy.

Screw height and weight standards

In a TikTok video (article link below) there is a female soldier calling out height/weight double standards between women and men. She brings a good point when you look at the standard of what it means being overweight when a lean women can't pass, but a clearly fat man can. She goes on to say what women have to do to get ready for ht/wt.

However, I think she doesn't see the big picture here. Women AND men struggle. As a guy who struggles with Ht/Wt every single time, I think I'm not alone in this sentiment. I'm lean, but that also means I have a pencil size neck which kills me. I see you CPT and SSG McFat passing ht/wt when you look like you ate a cow.

As a side note, for the 2nd time on my army life, I met the weight standard (189lbs) and gave the scale the middle finger. Screw you ht/wt standards!

Weight chart on Atomic xc skis

Hey there,

I have a question regarding the meaning of FBW value on this chart for an Atomic Pro C3 Skintec xc ski

I understand that the 0.52 mm value refers to the height of the ski base when Full Body Weight is applied at the balance point of the ski.

Yet, I can not figure out if:

1-that value is the average ski base height measured across the ideal skier weight range for that ski (i.e., 132-150 lbs) at FBW

or

2-that value is the ski base height measured at FBW for the mid-weight of the ideal skier weight range (i.e., 141 lbs)

or

3-anything else I am missing in that matter πŸ˜„

Many thanks for your help !

Tired of weight double standards in dating

I know this post will probably get me a lot of hate, but it's something that has just been building up in me for awhile.

I've had a big trouble dating, not going to lie. I know it's because I'm a bigger dude. But I'm just so done with the double standard with weight in dating. I see so many ads, profiles, etc.. of heavier women who call themselves a bbw,ssbbw,curvy,plus size or what have you and will have it say that they only date thin or muscular men. Really? I once said I like thinner women in a personals ad I posted on an old account and I got nothing but hate for it. It seems the "every size is beautiful" crowd only likes that for women and gives them the "you go girl! Get your man!" speech to them.

I'm really getting close to being done with dating. It's just getting more and more frustrating at this point. It seems women just get nastier all the time. And I'm not saying it's all women, but a vast majority of what I have seen are like this. I just don't understand the difference between a heavy girl wanting a thin dude or a heavy guy wanting a thin girl. But apparently it just means I'm some kind of pig who has an unreal expectation of women. But some how that doesn't apply to women at all?
