From me +1 for the TeX whitepaper.

And I actually did read it. Sorry: Another "I made this shiny coin and by issuing it, I hope to make tons of money".

Quote
Some users may elect a minting process instead of purchasing a “DinarCoin”. This creates
a reverse process, where the user deposits funds (directly or through an agent) to the LP.
The LP then places a sell order and once the order is executed a corresponding position is
opened and an XAU contract is associated with the minted coin.

This is really not even "minting" (let alone "mining").

A different flavor of Ripple.

final verdict: no

Ne ich kann die Nasen da oben einfach nicht mehr sehen.  ...
Deutschland kann man nur noch von außen helfen.

Ja, die Gesichter sind recht unerträglich geworden.

Hinsichtlich "Hilfe" wird es aber so kommen, dass sich Deutschland "von innen" ... äääh ... "umstrukturiert".

Das kann man von außen schön vorausschauend beobachten.
Gefallen tut mir das nicht. Ein Land mit komplett dysfunktionalen Selbstheilungsprozessen ist kein schöner Anblick.

Billiger kriegt ihr aktuell nirgend wo Strom

Ich habe Mai bis Juli im Schnitt jeden Tag 50kWh nicht nur für umsonst, sondern ich weiß (fast) nicht wohin damit.
Sind 25KWp auf dem Dach und die sind sogar für Winter optimiert, sonst müsste ich mit knapp 100kWh kämpfen.
Der Strom wird teilweise im Warmwasserboiler verbraten und die Familie gezwungen sich jeden Tag mindestens 10 Minuten mit warmem Wasser berieseln zu lassen.

Und wie machst du das bei Druckern die selbst speichern?
Das ist auch ein Problem

Hierzu als Ergänzung, dass ein jeder Drucker heute auf jedem Ausdruck irgendwo ein paar Pixel hinterlässt, die auf Modell und Seriennummer schliessen lassen können. Das "heute" kann man locker als "seit mindestens 10 Jahren" interpretieren.

Also irgendwo Papier klauen, mit Handschuhen wg. der Fingerabdrücke und irgendwo ausdrucken -> der Empfänger kann trotzdem herausfinden auf welchem Drucker welcher Seriennummer das wann gedruckt wurde und heutzutage vermutlich bald danach auch wo der Drucker physisch steht.

Ich empfehle alte Nadeldrucker.

If you don't want to (or can't) disclose details of the current "big project", maybe you could at least share a pointer to past successful "big projects" of yours.

Right...

"Big Project" -> "Many People" ->

has to be really really successful, because then it would have to feed "many people".

High performers, who actually would be able to pull something like that off, know what to look for before they engage.
This thing (what to look for) I would like to call "proof of work" (because in crypto context it has a funny ambiguity to it).

By proof of work in this context I mean if you want to gather capable (yes? hopefully?) people around you, you have to present already something done, some resources, some proven track of record. In short, you have to prove yourself!

This is actually quite the opposite from "Grow the project from zero together".
It would be: "Look here, I have done this and this and THIS already, so let's build on that..."
This "from zero together" could only work, if you had plenty of charisma - and I haven't seen proof (or even glimpse) of that either.

-have relations with many countries.
-Build our own businesses

You know - it's called

megalomania
ˌmɛɡ(ə)lə(ʊ)ˈmeɪnɪə/
noun
obsession with the exercise of power.
synonyms:   delusions of grandeur, obsessionalism, grandiosity, grandioseness; More
delusion about one's own power or importance (typically as a symptom of manic or paranoid disorder).


In severe cases, you can get a medication for/against it.

LBC going down around 20:00 UTC, downtime about 30 minutes. (= should be up 20:30 UTC)

New IP will be 185.157.21.48, should the DNS not catch up soon enough, you could enter that in your /etc/hosts
for lbc.cryptoguru.org

Post quality should not be determined by just the size of your post. The only reason it is done here is because that is the easiest way to gauge post quality, but it is most certainly not definitive nor accurate.

Now I understand why some Gonzos here do full quotes  of long posts only to add a "Well done!" or similar.

I'm sure you will find a better algorithm yourself, but in case you'd like some input, feel free to PM me. I have done some "text quality metrics" in the past, so maybe you could get some inspiration from that.

1310  Bitcoin / Project Development / Re: Large Bitcoin Collider (Collision Finders Pool) on: November 18, 2016, 04:42:10 PM



I let it run overnight and tried running it again. This is the result.

LOL.

By typing something which belongs on the command line as input to the LBC itself, all it got was "q" which it interprets as QUIT.
Try to input the query command on the commad line. In your case like this:

Code:
[osboxes@osboxes collider]$ ./LBC -q

And you should actually see an output similar to this:

Code:
Server answer to 'query' is:
{
"lastsee" : 1479426435,
"ips" : {
"111.222.111.222" : 3104,
"192.65.33.65" : 234
},
"done" : 2817168
}
'done' means we have delivered   2954.015 valid Gkeys.

You have to distinguish between "when the program runs" (then it listens to the keys "e" - end and "q" - quit)
and "when you are on command line" (then you basically are starting LBC)

Der Server ist natürlich noch in Betrieb und das wird noch ein paar Milliarden Jahre so bleiben.  Wink

Wenngleich mit kleinen Unterbrechungen.
Diesen Sonntag Abend wird der Server wegen Umzug ca. 30 Minuten offline sein.
Da das länger ist, als die Client Retry-Zeiten, wird ein Restart der Clients nach dem Termin notwendig sein.

Ich empfehle, die clients nicht mit extra-langen Arbeitszeiten zu starten (-t 30 ist ok), damit nicht unnötig viel Arbeit verloren geht.
Vermutlich setze ich hier noch einen PING ab, bevor wir mit dem Umzug beginnen.

1312  Bitcoin / Project Development / Service outage sunday on: November 18, 2016, 09:55:17 AM
Sunday evening (UTC) the LBC server will move to newer greener pastures and there will be a downtime of about 30 minutes.
Because this is longer than the retry-time of the clients, they need to be restarted after that.

I'd suggest to start your clients with "-t 30" so in any case there would not be much work lost.
I'll probably PING here shortly before we shutdown and move the server.

1313  Bitcoin / Project Development / Re: Large Bitcoin Collider (Collision Finders Pool) on: November 17, 2016, 11:20:01 PM
Earlier I ran ./LBC -q to see my status, and it quit. Going to have to reread the thread to work everything out.

Which happens if you query the status before having delivered a single block.

Before rereading the thread, I'd suggest the manual: http://lbc.cryptoguru.org:5000/man/user
where I try to have the distilled information from the thread.

perl LBC -c 2 -t 600
Fetching adequate work... Malformed answer: server didn't send minversion requirement.

Der Server ist natürlich noch in Betrieb und das wird noch ein paar Milliarden Jahre so bleiben.  Wink

Die Meldung ist interessant, denn das ist einer der Tests mit denen der Client checkt ob das gegenüber ein legitimer Server ist.

./LBC statt perl LBC, aber das ist nur rein kosmetisch. Was sagt denn

Code:
./LBC -v

?? Wenn das älter ist als 0.899, einfach neue version holen:

ftp://ftp.cryptoguru.org/LBC/client/LBC


Die sollte sich auch künftig selbst aktualisieren.

I'm new to Linux, so please forgive my stupid questions. Ive installed the required programs listed in your manual, but when I try to run the script, I get the "command not found" error. I'm running it with sudo.

I also tried using "sudo perl LBC.pl -h" after searching for a while, but it returns a BIGNUM error and says that JSON isn't installed.

I installed the necessary programs and downloaded your script to my desktop. Am I missing something obvious?



It does not need the .pl extension, but you may need to invoke it like that

Code:
sudo ./LBC -h

the ./ is necessary, because . (the current PATH) is often not in the $PATH environment variable.
The messages upon 1st invocation are plenty and may look quite disturbing.

(the program is mentioning what is not installed and will install the required modules. During that installation, it shows the output of the installation, which is terse.)

Let the program vomit and wait for a while, eventually all will settle and the help will appear.

1317  Bitcoin / Project Development / Bitcoin - RIPEMD160 on: November 15, 2016, 12:32:12 PM
Spent 48h quality time with RIPEMD160, have fastest C implementation of bitcoin-specific (a.k.a. 32byte input) RIPEMD160 in da world! (for 64bit CPUs)
Take that brainflayer, supervanitygen and Linux kernel!

All of this is necessary to be able to understand what I'm actually doing when programming the OpenCL code.
Learned a lot about GCC and even spent half a day f*ing assembly programming. Which is fun until you see what code the C compiler generates.
I've put the generated assembler source on the FTP server:
ftp://ftp.cryptoguru.org/LBC/source/ripemd160_256.zip

The *-0 is from the original https://github.com/ryancdotorg/brainflayer/blob/master/ripemd160_256.c
the *-latest is mine, about 20-30% faster.
Evolution may be visible:

Code:
-rw-r--r--  1 root root   34149 Nov 15 09:22 ripemd160_256-0.s
-rw-r--r--  1 root root   32182 Nov 14 11:21 ripemd160_256-1.s
-rw-r--r--  1 root root   33774 Nov 14 11:52 ripemd160_256-2.s
-rw-r--r--  1 root root   32899 Nov 14 13:08 ripemd160_256-3.s
-rw-r--r--  1 root root   32899 Nov 14 13:23 ripemd160_256-4.s
-rw-r--r--  1 root root   32724 Nov 14 14:29 ripemd160_256-5.s
-rw-r--r--  1 root root   32856 Nov 14 14:41 ripemd160_256-6.s
-rw-r--r--  1 root root   32236 Nov 14 15:02 ripemd160_256-7.s
-rw-r--r--  1 root root   29246 Nov 14 16:31 ripemd160_256-8.s
-rw-r--r--  1 root root   28825 Nov 15 10:01 ripemd160_256-9.s
-rw-r--r--  1 root root   28253 Nov 15 13:12 ripemd160_256-latest.s

I still can't believe, that the C compiler generates better assembly code than me, but then again I learned assembler on small MCUs and have not much experience on modern x86_64 architectures. If anyone believes he can manually improve the assembly in ripemd160_256-latest.s - feel free.
I also can't believe the compiler doesn't generate any AVX(2) code, so if you see optimization potential there, feel free also.

Why did I look at RIPEMD160? I benchmarked the various components in HRD-core and the result was:

Code:
29.20s     total runtime
19.82s     - 2 x RIPEMD160
13.67s     - 2 x SHA256_Update
13.60s     - 2 x bloom check
 7.98s     - 2 x SHA_Final
 0.10s     - sec256K1_ec_pubkey_batch

(results for the original code). RIPEMD160 now takes about 2 seconds less.
I'll push a new HRD-core generator to the FTP soon. No need to do anything, LBC will auto-update on startup.

1318  Bitcoin / Project Development / Go Generator source code on: November 11, 2016, 09:48:48 AM
I have released the source code for the old Go generator. You can download it here.

This was used by the first versions of LBC and as you can see, it's a very stripped down version of

https://github.com/saracen/directory.io/blob/master/directory.go

actually, it's a stripped down version of the "compute" function in there.

After compilation, you can run it like

Code:
genh160 "block-number"

and it will vomit about 40MB of binary stream to your screen.  Wink

So you might want to do

Code:
genh160 "block-number" > file

That file is 2 x 220 hash160s (each 20byte). "2 x" because it's for the compressed and uncompressed public keys of the respective private key.

Last night I pressed 'e' and then enter and I just logged  in and the screen session was dead, so it worked.

I was probably just impatient and using a large time of work.

Good to hear.  By the way, I use tmux - even when starting it up on my local notebook.
If I have to restart the complete X window system, the LBC in tmux still survives all of
that nicely. Screen probably does the job too, but it's such an old and crufty code...

On a side note, the pool just searched 47 bits of the search space and covered the equivalent of 1.1 trillion pages on directory.io
At the current pace we are checking around 265000 pages on directory.io per second.

For example, you would buy $100 AWS code for $5 worth of BTC?

More like $2000 for $100 worth of BTC. $100 is too small volume.

If you have e.g. codes which are valid only for a short period of time, I can use them and the price should be ok for something which is about to expire within 1-2 weeks.

Yes, I have now the means to burn $2000 AWS credit in a week.  Grin
