Edit: seems I was wrong about the escape mechanism for helium, it seems the primary mechanism is polar wind escape.

Also, hydrogen can also apparently escape from the Earth.

The redefinition of the mole in 2019, as being the amount of substance containing exactly 6.02214076×10^23 particles

Since the 2019 SI redefinition, avogadro’s number is a constant.

Edit: looks like we were both right! I was reading through your link and it seems the work reported by the NIST led to the exact definitions for Avogadro’s number and the Planck constant.

I think this would likely be most troublesome on some of the OG internet users that got a whole freaking /8, /10, or /12 or something like AT&T or universities. Up until very recently, and possibly even to the present, these organizations had such large IPv4 space, that there was no need to do NAT, and each device had a publicly addressable IP.

Since 2019, the kg is just defined in terms of the Plank constant and some math with the resonant frequency of cesium as well as the speed of light. There was too much variability in anything physical so they decided to just fix some constants at whatever value they were close to.

God I am painfully unoriginal

At the height of the French Revolution, he was charged with tax fraud and selling adulterated tobacco, and was guillotined despite appeals to spare his life in recognition of his contributions to science. A year and a half later, he was exonerated by the French government.

Goodness

I mean too much Helium isn’t a problem. It’s one of the few (only?) elements that will just disappear if you don’t do anything with it.

It’s light enough that it rises to the very tip top of the earth’s atmosphere and is then stripped away by solar radiation. That’s why is a depleting natural resource, not because it’s burned or used or anything, but because it just escapes.

unless you're sending megabytes of text or something

That’s exactly what someone malicious would do though, either in a single password submission or DOS via the password maximum repeatedly. IMO there is no functional security difference between a 64 and a 256 character password, so the NIST 64 character max is reasonable.

You can also just run it when you need it rather than having to add an extension. Just add a bookmarklet with the code here and just click it when you encounter a problematic website.

It’ll reduce your attack surface while still getting the job done.

When sharing a post, the app defaults to using the URL from the home instance of the poster. I’d prefer to share the link as it exists from my home instance.

The scented water is part of the new Baby Dior skincare collection, which also includes a $115 moisturizer for babies and a $95 cleansing foam.

 

With the state of Amazon currently, I can’t tell what is good and what is crap on there anymore. So I wanted to ask you fine people if you had any recommendations on cappuccino mugs. Not super worried about cost, but also don’t want to break the bank for some mugs.

Any recommendations / thoughts appreciated!

 

Hello!

I recently got a new espresso machine (a Breville Barista Express if that helps at all), and I have no idea how to get started picking espresso beans. I think I’d like a milder, darker roast for either lattes / cappuccinos but also good for drinking straight.

Where do I even go about finding a good bag of beans? Are there any recommended sites? Do you just go to your grocery store?

Any other advice for a brand-new first timer?

Any help is greatly appreciated!
