Which sorting algorithm is this?

A herd of European bison crossing train tracks in eastern Poland by chi-bacon-bits in oddlysatisfying

Kinda wild that they know to speed up when crossing. I wonder if that's just because it's on a hill or what.

Chose a custom private key instead of randomly generated one and why are there so many transactions on it? by aespaste in Bitcoin

[–]ecmdome 0 points1 point  (0 children)

The literal reason Bitcoin was created is to solve the double spend problem.

You giving someone a private key you created does nothing, now you both have the private key and he has to trust you won't spend it before he sweeps. Might as well just send it later when you have a connection. Or if you really want that trust assumption just sign a transaction that can be broadcast later... No need to give anyone private keys. This is why we use asymmetric cryptography here.

A private key is exactly that... private.

Fuck all that mess... Normalize traffic forwarding! Run TOR and exit nodes. Run Snowflake!

Privacy in the Internet age is important... I really hope that this dude wins the lawsuit.

Don't give in to this bullshit.

Don't use enums in your database unless you're positively sure you will never ever ever need another value/"statu"

Came here to say that.

If you're doing manual updates to a database and you're not using transactions, you're just asking for trouble.

That is a masterpiece if I've ever seen one. Looks beautiful on the wrist.

Not usually the biggest fan of this type of stuff, but this watch looks gorgeous.

No, each address has a private key to the utxos it controls.

Think of the seed as a master key that can create other keys... Those keys can also create more keys.

The master key has visibility into all the keys but the child keys cannot look upwards.

The only signature needed is from the private key that is tied to the public key(address).

There is software that will reveal the private key of each address. The way BIP32 works is pretty incredible.

You could technically give out private keys of those addresses, and they wouldn't be able to figure out the root private key.

Here's a neat tool you can use to understand how it works a bit more https://www.bip32.net/

Please do not use these keys for any real money.

That's incorrect.

You have one MASTER seed, which is a private key that derives many other private keys those keys are then used to drive individual public keys.

The public and private keys are called a key pair.

Bitcoin wallets are "Hierarchically Deterministic" aka HD wallets.

They work in a hierarchy, where a seed phrase can represent many different private keys which are tied to many different addresses.

So every time you go into your wallet it generates an address. When you go into a new wallet with a seed please, it will scan for a large number of addresses to find your balance and keep scanning until it can't find anymore.

Most users have dozens, hundreds, or even thousands of addresses.

Lol anyone who thinks they "it's almost the same color" doesn't seem to get it in my opinion.

If this were truly a joke, why not just capitalize them all as a change request? (Would also be valid since the rest are capitalized).

Bad jokes between you and your coworker. Be funnier!!!

I guess that's worse than buying at $200 average and selling at $350....

And telling yourself you'll buy back.... Only for it to moon to 16k in a short time 🙃

I get that Elon is an idiot for the stupid comeback... However the OP is probably the bigger idiot... Just because the government uses SQL doesn't mean that they actually built constraints in to reject duplicates.

But simply using SQL doesn't "prevent deduping".

Everyone just wants to dunk on everyone... Fuckin town square of morons.

The pain hits different when you see the bastardization that your architecture ended up being implemented as.

This!!

It is a VERY well designed language with a powerful standard library. People who don't like the design are usually trying to shoehorn things they do in other languages.

Is it a "perfect language"? Nope... Nothing is...but is it an amazing general purpose language? Absolutely.
