the beauty of a conspiracy theory is into making people believe that something happened (or could have happened), even if nothing did happen.

a conspiracy means "plan a criminal act", not "crazy story"


if it means "crazy story", it would be a brilliant legal defense in a court case.

Judge: "Mr. Neurotic Fish, you are charged with conspiracy to commit murder, how do you plead?"
NeuroticFish: "Oh please, you're prosecuting me with a theory, about a conspiracy? You can't be serious!"

Presumably you also think you'd win such a court case like that? Roll Eyes


if "conspiracy" means "fake bullshit" all of a sudden, the court system and the legal system need to change what their definition of that word is, and they need to do it quickly.


Or, maybe you could just, I dunno, learn what words mean before you use them?
842  Bitcoin / Bitcoin Discussion / Re: Statistics: Geez, I thought there were more females in bitcoin community on: October 13, 2019, 10:44:15 AM
There could be tons of them. If I were female why would I bother mentioning it?

I especially wouldn't make myself known here as I've seen some EXTREMELY strange reactions when someone outed themselves as one of those impossibly exotic creatures.

exactly

it's well known that women discussing technical subjects on the internet are engaging with the subset of the male demographic that is least likely to handle female company gracefully. Tech women learned a long time ago simply to not mention they are female, as it doesn't add anything to the discussion, and is almost guaranteed to cause some problem/friction eventually.
843  Bitcoin / Development & Technical Discussion / [meta] Rust in Bitcoin reference implementation on: October 13, 2019, 10:31:26 AM
Rust is a new-er programming language, and has a reasonably good reputation:

  • liked for being more difficult to make mistakes with than C/C++ (although not impossible, of course)
  • for being sufficiently powerful in expressiveness, yet relative simplicity compared to C/C++
  • disliked because compiling the actual Rust compiler was until recently not possible (we have gnu's guix system to thank for that)

So, there's been a Rust implementation of Bitcoin around for a while, and some good programmers actually preferred to spend their time re-implementing the existing Bitcoin client in Rust than to work on the reference C++ implementation. Which is a good plan in and of itself, as a proof of concept if nothing else.


There are now plans to implement Rust code into the main Bitcoin implementation: https://github.com/bitcoin/bitcoin/issues/17090

speaking as a non-expert on either language, but as a Bitcoin user who does understand something about coding and computer science, I'm unenthusiastic about this.


I understand the rationale:

  • Rust code has lower review burden
  • The plan is to duplicate non-consensus C++ code, to add redundancy to network consistency/reliability
  • Rust is proven these days, compiler can be bootstrapped

that's all ok.

however, one plan is not to use a Rust compiler that is bootstrapped from a trustworthy source (Canonical's Rust compiler). Call me nuts if you so choose, but that seems like a very cavalier decision to make with software that should be putting security first. You can say "trusting Canonical is subjective", in which case, it should be ruled out altogether in such a critical piece of software as Bitcoin

my other concern would be the "thin end of the wedge" argument.

The rationale for putting the specific Rust code into the Bitcoin codebase is sound; if headers fetching code fails in some unknown circumstance, maybe only the C++ implementation of the headers fetching code will fail, and the Rust headers fetching will continue to function without incident. Hell of a supposition to make, but it's somewhat reasonable, as there is some acceptance that Rust can be written in such a way that certain types of bug are less likely (but not impossible)

But this would make it too easy to say "let's just re-write the main implementation in Rust, piece by piece! After all, failover Rust code is working great so far!"


In the end, such a radical change (I'm sure that statement will be a point of contention, but it's essentially self-proving by the virtue of the fact that this is a contorversial change of direction) was always bound to be divisive.

The developers who are keen to send Bitcoin in this direction should realise that there's no real practical difference between doing something divisive for good reasons, or doing something divisive to cause problems in the project.


usual thread rules, + 1 extra:

  • no trolling
  • no trolls
  • discussing personalities or intentions or politics of those debating is not allowed, and will be removed, e.g. "Bjarne Sostroup says x about Rust" is disallowed, everything must be provable in it's own right, here in the thread, written by you

the technical merits and the consequences to how the Bitcoin project is managed are the focus of this thread
844  Bitcoin / Bitcoin Technical Support / Re: Raspberry Pi 4 performance on: October 13, 2019, 09:42:36 AM
I'm going to wipe and start again, but I was wondering if it was just me.

I would look for any changes made to the

  • linux kernel image
  • linux firmware
  • startup config (so, /boot/config.txt and /boot/cmdline.txt)


...relating to this latest update to Raspian, that's where any potential problems may have crept in. roll back to the old version to see if you can confirm the issue, then report that online (raspberry forums are best IMO for that)

these Pi-style computing boards are really not designed to be always-on servers, so getting them to work that way takes some additional effort. It can be done though.

there's another possibility: wipe an SD card too many times (or write too much to it in general) and you'll begin to increase unreliable behavior from the card, it's low quality flash memory that deteriorates quickly. It's better to use a SATA disk over a USB hub, particularly with the Pi4, as the Pi4 has a new SATA-over-USB protocol to improve that kind of setup (your USB hub needs to support the new protocol though)

I was near the end of downloading the blockchain data or blk?Huh?.dat when it started getting "warning 52 of last 100 blocks have unexpected version".

That warning is benign. There is no way to get rid of the warning, and that the warning exists does not cause any problems. You can safely ignore it.

I'll add that this happens because some Bitcoin miners decided to mis-use the protocol in a way that boosts the performance of their mining rigs.

and also to reiterate: this does not cause any problem, it doesn't matter in reality

benign warnings have been removed from normal logging before (1 just recently), there's a case to do that for this warning, or at least to change the text from "warning" to something more appropriate


I was able to figure out that when my 256GB SanDisk card got full, it was able to restart when I -prune=550 !
[snip]
I might get a 512GB SanDisk next time that'll cover the blockchain data.  200GB is not really enough for Bitcoin blockchain data anymore!

this, however, will cause you a problem. I think we reached the point where 256GB disks were unusable a while ago
845  Bitcoin / Press / Re: [2019-10-10] How the U.S. Government Tried – and Failed – to Shut Down Bitcoin on: October 13, 2019, 08:47:43 AM
Like in many conspiracy theories, everything is written in a shady manner.
The title tells "has revealed that her boss at the U.S. Attorney’s office asked her to look into shutting down Bitcoin"(*)
The "there’s this thing called Bitcoin and we need to investigate it"(*) part can be seen as a something normal or, if your head is conspiracy-oriented, can mean the introduction to anything bad you can imagine.
The article continues in a "conspirationistic" manner "While the U.S. Department of Justice’s (DOJ) goal may have been to shut it down"(*)

As people that understand (better or worse) Bitcoin, we know that Bitcoin cannot be "taken down" like this. Hence no crime. Still, it has all the ingredients for a conspiracy theory.
(Just as a clearer analogy: everybody who knows a tiny bit of physics understands that Earth is not flat and cannot be flat, still this doesn't stop the growing club of flat-earthers.)

I don't understand where the confusion was/is.

do you understand how to answer a simple, 1 dimensional question? you're so confused, you don't even know what you're confused about Cheesy


what crime was committed? you seem to think there was, what was it?

Now when we are against them and asking for our rights they are doing this for us.

no need to ask, take your rights

but don't expect people to respect you if you believe you have a right to destroy their possessions.

be very careful which direction you point your moral compass, especially when you have this very tense situation

to win, you must keep other Hong Kongers who do not protest on your side. Chinese/HK gov know that's powerful. They will try to get the non-protesting people to dislike you, which is why you must be so careful.

Plants and ecosystems can't just up and move as the climate changes.

if (that's an if) weather patterns and ecosystems are changing significantly, plants literally will up and move, as plants have multiple ways of propagating their offspring, and it always involves making use of either ecosystems or weather patterns (e.g. wind carries seeds; birds eat seeds and excrete them elsewhere)

nature's got it covered, and has been like this since the beginning of life. it's a dynamic system that has survived because of how well it adapts to adversity, and has done so in far more adverse conditions; for instance pre-life nothingness

Life started from amino acids & proteins created from natural processes, then winding themselves into naturally occurring RNA (how this naturally occurring RNA became the early bacteria that started life is, I believe, still unknown). This all happened with very high levels of CO2, 10%+, and virtually zero% oxygen.

To think that 0.04% CO2 levels can turn the Earth back into a planet that cannot support life is incredibly short sighted, and frankly, more than a little hubristic.

It's in the article, it seems she wised up.

you're equally confused.

Neurotic Fish was suggesting this US Attorney made a plan to commit a crime, I'm saying that wasn't in the article. Despite how prevalent corruption is in US government departments, US Attorneys are usually prosecuting crimes, not planning them

If the child transaction is confirmed and included in a block, then the parent transaction would have to be in the same or a previous block as well.

right


Not sure about taint, maybe it won't, but do we know how companies like chainalysis works? Or do they use the same definition of taint as blockchain.info (.com) used to?

it's more about how actual Bitcoin transactions work, and whether this specific case (CPFP) segregates the inputs of the parent from the child.

Also don't forget that there are satellites now. Blockstream satellite should even be able to cover North Korea. With some effort, one could also make sure that mules bring in the required hardware to utilize the satellites.

Not 100% that I have the details right, but there was maybe a story about the collapse of the USSR that demonstrates how even mundane technology can tip the balance in fragile regimes; supposedly, middle-class Russians used fax machines to communicate coded messages to their anti-regime friends, and to print information pamphlets for the people without a fax machine.

If a country successfully bans miners, it still won't affect Bitcoin's network much, because mining is spread across the world, the worst case if it happens suddenly and in a country that hosts a large portion of miners, but even then it would just result in some temporary disruption.

and Lightning doesn't need mining to fundamentally operate. So, miner bans are even less disruptive the more Lightning is being used, it's effectively a hedge against any type of disruption to the blockchain layer (but the channel liquidity is of course restricted by however much is available before any problem starts, and at what rate new channels can be opened in the adverse conditions)


so, on-chain disruptions (like miner bans) are a bit pointless to attackers really

And bow down to their God
Lost the culture, the culture lost
Spun our minds and through time
Ignorance has taken over
Yo, we gotta take the power back!
Bam! Here's the plan

Step back, I know who I am
Raise up your ear, I'll drop the style and clear
It's the beats and the lyrics they fear
The rage is relentless
We need a movement with a quickness
You are the witness of change
And to counteract
We gotta take the power back"

If it was ever possible to break sha, bitcoin wouldn't worth thousands of dollars because it would look just stupid to rely on an asset that is subject to a mathematical or technological  development which could occur every moment.

you are speaking as the person who infamously claimed that SHA-2 ASICS broke SHA-2:

Actually ASIC is a crack against cryptography, it has always been since WWII and nothing has changed, when a cryptographic algorithm get ASICed, it should be considered a failure and fixed instead of being justified as 'inevitable', 'not a big deal' or even 'a good thing'!
It is just ridiculous how is it possible to have a cryptographic system of any kind being cracked by a specialized circuit and considered safe meanwhile?

It's interesting how the community has known about this all of along, while mainstream outlets report this as something sensational or just found.

BTC can play a significant role not only diminishing the control of the government over how the population transacts, but also protects individuals from the imminent depreciation of the currency that they hold. Again, this simply proves critics of bitcoin who say that it has no practical use completely wrong.

it's a reflection of the power interests at play. The implication is that people like Steve Forbes can afford to take the risk of saying this, but (as you point out) late compared to the internet fringe that made Bitcoin popular.

it also implies the regular newsmedia cannot afford to risk even printing the contrarian internet-homegrown perspective on this (and it's really nothing short of reality to say that Bitcoin empowers people, both good and bad).

the overall implication is that all of the media will repsresent a very biased view of Bitcoin, and a view that is biased in favor of the existing (corrupt) financial system. Even the media that are critical of the financial system are curiously critical of Bitcoin.

The highest efficiency coal plants are in the mid 30 to 40ish % efficient. Modern gasoline engines in cars are about 30% efficient with older models being lower, and some newer models being in the upper 30% range, with diesel vehicles being more efficient than gasoline. The world needs to change its power supply (not to solar...) before electric cars are any better for the environment than gasoline or diesel burning cars.

you see, this is where you guys are getting this so incredibly wrong


you don't have to threaten me with breathing taxes or certain extinction of human life to convince me that we can and should improve the efficiency of vehicles and powerplants, or that the current designs pollute in several ways that are not controversial.

what's wrong with compromising on your propaganda, when I can be so easily convinced that electric vehicles and non-fossil fuel power plants are good ideas that *I am* willing to pay for, for what I consider to be good reasons?
