Sharpiemarker , to Ask Science in Hi, can someone explain to my small brain what reaction this is or what happened?

Copper metal "dissolves" in nitric acid (HNO3). Actually, the nitrate ion oxidizes the copper metal to copper (II) ion while itself being transformed to NO2 gas in the process; the copper (II) ion then binds to six water molecules.

Unlike Apollo, will this be Free Software though?

Apollo did have a free tier and then a few paid tiers.

iirc, (I bought it many years ago), they had a one time Pro purchase that removed any ads and unlocked theming and such, and then the Ultimate which was a subscription to cover server costs of push notifications (although it did eventually end up having more features locked behind it).

While I personally did not go for the Ultimate subscription (didn’t really need the push notifications), I gladly paid for the Pro as it was well worth it IMO.

I think they meant Free as in Open Source

Freesoftwareenjoyer ,

It’s not exactly the same. The Free Software movement is about user freedom. Open Source is a term used by corporations to avoid mentioning that users should have rights.

Time to get him a jolly ball

its_prolly_fine OP ,

He only lives things he’s not supposed to mess with. He had obe when he was younger, didn’t care about it at all! Lol

Everythingispenguins ,

Seems like a pretty standard horse there 😂

aeternum , to aww in Meet Birdie, our new rescue!

Thank you for rescuing. Rescues are every bit as loving, and definitely deserving of a loving home.

My girl was in the shelter for like a year, because she was an old girl. I adopted her when she was 11 and now she's 15.

abbadon420 , to aww in Meet Birdie, our new rescue!

I hate to break it to you, but that’s not a bird. Though as a fellow dog person, I can understand the mistake.

fiat_lux , to aww in Meet Birdie, our new rescue!

Have you received your first purr yet? Did it feel like you'd won at life?

Radioactrev OP ,

This cat is a purring machine! She was only available for adoption at the shelter for one day. The staff knew she’d be picked quickly.

But yes, winning at life. I read somewhere you should record their purr so you’ve always got it.

fiat_lux ,

Audio and video, I promise you both are good ideas!

Y'know I never realized it until just now, but...

Why does a Borg need an 8-pack?

UnfortunateTwist , to fountainpens in My first Nakaya

Beautiful pen.

Question for the more experienced: is this a case of the feed not being able to keep up with ink usage?

argv_minus_one , to RedditMigration in Reddit has started assigning power mods to subs they took over.

I was wondering when they’d get around to doing that. RIP Reddit.

Is this a spot? Then it’s a perfect spot to sleep for cats.
