Many classical email clients have the option to edit the senders address while composing the email. If the mail server does not allow this you usually get an error message on sending.

You are technically correct in saying that it's not a registration. Instead it's a sponsoring: https://en.wikipedia.org/wiki/Sponsored_top-level_domain

UDMH

At least that stuff is stable while in a tank. Imagine sitting next to tons of rocket grade hydrogen peroxide, slowly decomposing, just waiting for an excuse to go boom.

If you mean an Immune escape that is not a real problem for rabies because that virus has a slow evolution as you can tell from the fact that the same vaccines that were used in the 80s are still used today. Compare that for example to flu or Covid-19 vaccines where even two year old vaccine types are considered outdated and not used anymore.

[solved] help needed to understand this diagram of a water flow sensor (from a boiler) in c/askelectronics@discuss.tchncs.de
[–] user134450@feddit.org 2 points 2 months ago

That is probably inspired by EN IEC 81346-2 where "X" indicates a connector of some kind and the numbers following the X identify the connector and the relative position on the connector (for connectors with multiple contacts).

Reddit Undeleted all my posts and comments in c/mildlyinfuriating@lemmy.world

Actually using AI gibberish for this might be the best strategy of all, since Reddit seems hell bent on making money with AI training and feeding AI generated text into AI training has been shown to yield increasingly worse results over time. So you make the product Reddit is selling less attractive.

Uncoated aluminum boiler with brass group head corrosion risk? in c/coffee@lemmy.world
[–] user134450@feddit.org 2 points 2 months ago (1 children)

ah ok i mistunderstood what the group head is. if they are both permanently in contact with the water in the boiler then it would depend a lot on the water quality. Water with only a little conductivity (<100µS/cm) would not be a problem for pure aluminium or most alloys, since the aluminium would passivate much quicker than the corrosion could dig into it.
i would assume that a vessel made for boiling water is made of a highly corrosion resistant alloy but i can not know for sure.

[–] user134450@feddit.org 1 points 2 months ago (3 children)

but that only happens while there is water there, right? so given the limited amount of contact time i think this is not a concern. aluminum has a great capacity for self-passivation too, at least the typical alloys do.

So what do you think when you work with HeLas?
