300 sats \ 2 replies \ @CruncherDefi 19 Dec \ on: [Not-so-daily puzzle] Nested roots science
Saw the hint before trying to solve all by myself :((
k = sqrt(7-sqrt(7+k))
k^2 = 7-sqrt(7+k)
sqrt(7+k) = 7-k^2
7+k = (7-k^2)^2
7+k = 49 - 14k^2 + k^4
k^4 - 14k^2 - k + 42 = 0
You can probably solve it analytically, but I quickly guessed k=2 looking at the numbers.

Increasing efficiency IS solving a problem of having low efficiency. What kind of question is that?
20 sats \ 1 reply \ @CruncherDefi 3 Dec \ parent \ on: Ecash on Bitcoin - Gandlaf thoughts on ecash, after working on cashu for 2 years lightning
I just gave it as an visual example. Other app developers might not be constrained by legal reasons when it comes to transferring out.
Also as an app developer I might prefer using open source standard and protocol rather than 3rd party solution like Stripe (or some other closed integration).
In this vision each app would be a small bank for its users and for their purchases.
22 sats \ 4 replies \ @CruncherDefi 3 Dec \ on: Ecash on Bitcoin - Gandlaf thoughts on ecash, after working on cashu for 2 years lightning
I always like to think that Ecash could be used by app developers to implement those various app-points or app-wallets thing. Think Starbucks app: you top up your wallet, you buy coffee later.
But that way instead of reinventing the wheel each time apps could use the common sound money protocol instead. Imagine the interoperability!

Slurp. That is some delicious russian propaganda! Do like!
I could point out methodological holes in your 'post', but we both know that you are not interested and would not care.

So you're saying that people need a "protector" and to delegate responsibility to him/her?
He never said that.
Having rules does not imply you have a 'protector'. You might be protector yourself. Or your community might enforce rules collectively. Or code/machines might enforce rules.
Communities were figuring out rules since all of humanity and it is okay.

Hashrate follows the price. If price goes up, more miners are spun up because profit margins get better.
0 sats \ 0 replies \ @CruncherDefi 7 Nov \ parent \ on: Jason Lowery releases his Bitcoin policy recommendations for the US government bitcoin
The way I understand it is that it builds on the idea of using bitcoin paywalls as a DDOS deterrent.
For example, if you require 1000 sats for trying to open an SSH connection to your machine you effectively limit capabilities of unwanted people connecting to you.
And if you think what kind of 'resource' makes sense for such use-case, bitcoin is the one. It's neutral (for example if you would use USD for paywalling, US could attack you as many times as they want, because they can mint new units). It's physics-bound, so there is upper bound of how many trials they can use (USD has no upper bound).
Think about 'waiting in a line to a doctor'. Can the doctor be DDOSed? Not really, his waiting room won't accommodate 1000000 people - there is not enough 'physical space' resource to fit that many people.
Because bitcoin is physics bound as well you can replicate this kind of limitations in the cyberspace in some sorts.
142 sats \ 0 replies \ @CruncherDefi 3 Nov \ on: [Daily puzzle] Light bulb problem science
Pick a switch A. Continually turn it off and on for a really long time (we want the light bulb to burn out). Turn on switch B. Switch C is turned off.
You go into other room.
Burned bulb was controlled by A, lit one by B, non-burned unlit by C.

Autistic, genuinely wants to progress humanity but with poor self-error correcting mechanisms. Also too much ego driven - he could use some humility here and there.

Have you considered that having a backup planet might be a good thing? It takes one unfortunate cosmic or geologic event to wipe us or significantly set us back.
Humanity must hedge those risks and going multi-planetary is the only way forward.

What about those "I confirm I am not from US/UK, as SN service is not available to those jurisdiction" modals? It seems this is the way many projects are going for.

275 sats \ 0 replies \ @CruncherDefi 18 Oct \ parent \ on: Why stablecoins and stablechannels are dumb bitcoin
When two things compete in the same category ("store of value"), they are either equal, or one is worse.
Nope. With enough experience you see that usually there aren't better/worse things - only trade-offs. Things are not one-dimensional as you suggest.
If they exist, blockchains and lightning channels are a worse place to do that than other systems like sql databases
What about people that are blocked from banking system? Uncensorability is the main feature of bitcoin blockchain.
They do not need to create these fiat-denominated obligations, and once entered, they usually have escape clauses
Citation needed. Of course most people have fiat-denominated obligations and saying they don't, won't change the factual reality.
44 sats \ 1 reply \ @CruncherDefi 4 Oct \ on: The ethics of borrowing in fiat, in order to buy bitcoin bitcoin
Regardless of ethics, it inevitable. It's just simple game theory.
Of course it would be better if no one did that (cooperation). That way we would smoothly transition into bitcoin system without people getting massively rekt.
But if someone defects and does that, others will get taken advantage one. So the only counter play is to defect yourself and also borrow fiat to get bitcoin.
Also this game was played for decades by rich with other hard assets already.
200 sats \ 1 reply \ @CruncherDefi 30 Sep \ on: [Daily puzzle] \sum{n=1}^m n^3 = \left( \sum_{n=1}^m n \right)^2? science
Yes, assuming it's true, it's true for both m and m-1. Lets substract both-sides of equations for m and m-1 and we get:
m^3 = ( 1+2+3+...m)^2 - (1+2+3...(m-1))^2
Rth side is two arithmetic series. We can simplify:
m^3 = ( (1+m) * (m) / 2 )^2 - ( (1+m-1) * (m-1) / 2) ) ^ 2 m^3 = ( (m+1) * m / 2 )^2 - ( (m-1) * m / 2 )^2
Divide both sides by (m / 2)^2
4m = ( (m+1) )^2 - ( (m-1) )^2 4m = ( (m+1 + m-1) ) * ( (m+1-m+1) ) 4m = ( 2m ) * ( 2 ) 4m = 4m

Facts matter.
Exactly.
Bullet flying in your direction pierces your body, it's a fact. Rocket flying into your house explodes, it's a fact. You can destroy a rocket with counter weapon, it's a fact. You repel kinetic force attack with kinetic force, it's a fact.
Your wishful thinking won't make those facts untrue. If one is getting attack physically, the only counterplay is to defend physically.
Si vis pacem, para bellum

This thread is showcase of how quickly the SN legend @DarthCoin can fall down and be exposed. I see nothing but rambling, ad-personams and zero logical thinking from the guy in this thread.
I hope it's an eye opener to regular SN users to not treat the guy as some kind of oracle.

Being apolitical doesn't give you rocket protection. Bullet flying in your direction doesn't give a fuck about you being apolitical.

Just stop with this idiotic bullshit.

Spend and replace. When Laszlo replaced the spend coins after pizza purchase, effectively no bitcoin upside profit is lost.

Tbh this kind of flow "You buy a game on steam, I send you btc" formalized in some app/protocol/nostr_convention with reputation system could be a cool bottom-up distributed alternative to things like bitrefill/robosats.
