oho thanks to you too
The moral of the story is:
Whale insiders don't just massively run up a thin market with leverage, unless they've got a way to also bring it down waiting in their back pocket....
I don't suppose you would give any names?

... (moving on) they didn't run up the 2017 market. Or am I getting that wrong?

pl somebody school me on the bear market from early 2014 to autumn 2015
esp.: was it about the 'scaling debate'
or 'Chinese dumping'
other factors
?

ps i get that i can just 'research it myself' - goddamn lazy newbies
but would be interested to hear from this array of commentators
9486  Bitcoin / Development & Technical Discussion / Some 'technical commentary' about Core code esp. hardware utilisation on: July 06, 2017, 10:22:38 AM
thought this was worth preserving - was thoroughly off topic in another thread and may get deleted.
haven't edited the quote so there's lots of political stuff which would be off topic here (but it is your board!)
please see @-ck's thread for some initial commentary on point 13. otherwise,
invite dev and tech regulars to comment

The thing to bear in mind is that Core have an exemplary record for testing, bugfixing and just generally having an incredibly stable and reliable codebase.  So while people may run SegWit2x code in the interim to make sure it's activated, I envision many of them would switch back to Core the moment Core release compatible code.  As such, any loss in Core's dominance would probably only be temporary.

In short, I agree there's probably enough support to active a 2MB fork, but I disagree that Core will lose any significant market share over the long term, even if the 2MB fork creates the longest chain and earns the Bitcoin mantle.

Nokia was also good at testing and reliability, where are they now?

And Core code is shit, anyone experienced in writing kernels/drivers, or ultra low latency communication/financial/military/security systems would instantly notice:

1. The general lack of regards for L0/L1/TLB/L2/L3/DRAM latency and data locality.
2. Lack of cache line padding and alignment.
3. Lack of inline assembly in critical loops.
4. Lack of CPU and platform specific speed ups.
5. Inefficient data structures and data flow.
6. Not replacing simple if/else with branchless operations.
7. Not using __builtin_expect() to make branch predictions more accurate.
8. Not breaking bigger loops into smaller loops to make use of L0 cache (Loop tiling).
9. Not coding in a way that deliberately helps CPU prefetcher cheats time.
10. Unnecessary memory copying.
11. Unnecessary pointer chasing.
12. Using pointers instead of registers in performance sensitive areas.
13. Inefficient data storage (LevelDB? Come on, the best LevelDB devs moved onto RocksDB years ago)
14. Lack of simplicity.
15. Lack of clear separation of concerns.
16. The general pile-togetherness commonly seen in projects involving too many people of different skill levels.

The bottleneck of performance today is memory, the CPU register is 150-400 times faster than main memory, 10x that if you use the newest CPUs and code in a way to make use of all the execution units parallelly and make use of SIMD (out-of-order execution window size, 168 in Sandy Bridge, 192 in Haswell, 224 in Skylake).

One simple cache miss and you end up wasting the time for 30-400 CPU instructions. Even moving 1 byte from one core to another takes 40 nanoseconds, that's enough time for 160 instructions on a 4GHz CPU.

You take one look at Core's code and you know instantly most of the people who wrote it knows only software but not hardware, they know how to write the logic, they know how to allocate and release memory, but they don't understand the hardware they're running the code on, they don't know how electrons are being moved from one place to another inside the CPU at the nanometer level, if you don't have instinctive knowledge of hardware, you'll never be able to write great codes, good maybe, but not great.

Since inception, Core was written by amateurs or semi-professionals, picked up by other amateurs or semi-professionals, it works, there are small nugget of good code here and there, contributed by people who knew what they were doing, but over all the code is nowhere near good, not even close, really just a bunch of slow crap code written by people of different skill levels.

There are plenty of gurus out there who can make Core's code run two to four times faster without even trying. But most of them won't bother, if they're going to work for the bankers they'd expect to get paid handsomely for it.

So while people may run SegWit2x code in the interim to make sure it's activated, I envision many of them would switch back to Core the moment Core release compatible code.  As such, any loss in Core's dominance would probably only be temporary.

In short, I agree there's probably enough support to active a 2MB fork, but I disagree that Core will lose any significant market share over the long term, even if the 2MB fork creates the longest chain and earns the Bitcoin mantle.

So even a Core fan boy have to agree that Core must fall in line to stay relevant.

A fan boy can fantasize everyone flocking back to Core after they lose the first to market advantage.

But the key is even if Core decide to fall in line to stay relevant, they can no longer play god like before.

So what's your point.

that's twice now that @empowering has come late to a thread promising laughs and activities

while his manifesto is now the most comprehensive, can he deliver it in real time?

can anyone else be bothered to expand theirs beyond a scattered line or two?

might mass changes of vote at this late stage stand Lauda a chance, which is something ~77% do not want?

Operation "Autism Storm" and UASF are two fronts in a culture war. MSM liars and Bankster Statists vs everyone. Something BIG is coming.



sorry, bored. things pretty bullish on twatter, though

They can mine the wrong chain, that's fine.

We had all this with BIP-66 two years and one day ago.

Even if Core buys a million new Raspberry Pi and run UASF tomorrow, they still have no game.

This may be the first thing you've said that has any grain of truth.

Quote from: LukeJr
Rather, what matters is not that you’re running a node, but that you’re using it to receive transactions. This is what it means when people talk about economic nodes: nodes that people use for economic activity. So, if you use the wallet built-in to your Bitcoin Core+BIP148 node to receive your bitcoins, you’re doing your part to enforce BIP148.

Your talk of 'critical mass' is just gibberish and shows you do not understand bitcoin.

Miners have no say in these matters.

Users do. We can flood you with more transactions than Bitpay ever made.

Go away and learn bitcoin. Then go away again.

btw, before you start, I am one of the least 'pro-Core' people on here, but I am even less of a fan of nChain, the fake satoshi Craig Wright, matonis, DCG and all your gang of scammers.

Go away and learn bitcoin. Then go away again.
9494  Bitcoin / Bitcoin Discussion / Re: The "Satoshi Risk" on: July 03, 2017, 10:21:01 PM
So I can tell you with confidence that you mined very few blocks (e.g. 10 blocks)  during that time and you're not millonaire, or you are part of the Satoshi group, period.

Do I get to be Satoshi too? I was off by only a few days... https://i.imgur.com/w57rtbs.png

I know first-hand that there were several different people who mined before January 2010. It's kind of funny that history I've lived through is being questioned...

This 1 million figure was thoroughly debunked long ago by many an old hand. Sergio was wrong about it, and so many things.

lol and largely agreed

^ref your earlier discussion - how to get (back) into bitcoin - and the advice you were given - dollar cost averaging - thought this might amuse/interest you/all/some: http://trilema.com/2017/the-universal-plan-for-wealth/

my main takeaway for the purposes of this thread -
it's incredibly goddamn bullish - a kid scrapes together $20k worth of btc now ... puts in some not very hard work ... is a wealthy man in ... ?several years' time.
20k becomes what 200mil? in today's terms

i'd bet most of us want to believe roughly that sort of growth for the price, even if my definition of wealthy is an order of magnitude more than the next guy's

if we are right, then the dollar will decline so sharply at some - nearish-by - point
that dollar-cost averaging will no longer be a way in to bitcoin for the average working stiff
