As other's have probably said, if they're just working on theory i.e. never had a working prototype, they won't have a demo model until 24hrs before they're going to ship some

if, which is what they should have done, is run a prototype model of one

of course they should do this and then have much testing etc. before mass producing so maybe up to a week minimum before shipping a batch they should have a working product; why not show it off?

Perhaps because, as I mentioned above, it would show nothing.  It would, in fact, be mainly a waste of time and Avalon may not have a compelling interest in impressing the segment of the community who would be be impressed by such a feat.

Again though, it would not be big effort or waste much time, so why not?  An ominous reason could be that it would be admissible,  incontrovertible, and documented evidence that they were running a scam if that happens to be the case.



You are right, it takes 5 minutes to take a reflex plugin the sd card and upload the pictures.
2 minutes using an iPhone.

That's a lot of time to waste.

I will buy BFL. Do someone want to bet against me that Avalon will not ship on time? 100BTC ready here.

non è che stai rivendo i bitcoin che il tuo amico mi ha fregato?

Dovevi comprarglieli e fare il chargeback! Tongue tanto sono "amici"...

Faccio fatica a credere alla faccia tosta di certa gente (che mi minacci di denuncia ora? Haha) @jahcopo, Diego è un ottimo trader e con postepay ti vende tutto quello che vuoi, te lo consiglio.

Why the hell is the forum unable to cope with the traffic given how much has been donated to upgrade the software?  Seriously, the software upgrade seems like vapor-ware at this point.

the forum needs to be running on http://www.litespeedtech.com/ instead of apache

which i have offered up a license 100% free for use on the forum (i'd even pay the support/updates contract)  (for sale in this thread https://bitcointalk.org/index.php?topic=122271.0)

Seriously ?
Why not simply use NGINX with PHP-FPM instead (If not already using it) ?

NGINX is already used by many large sites and is blazing fast - I don't think there will be much debate over it.

PHP-FPM is slightly faster than SPAWN-FCGI or custom script dispatcher, but consumes much less memory (as all php processes share memory).

Also, moving from MySQL to MariaDB could be helpful. "Normal" MySQL is not really developed anymore, as Oracle does not give a duck about it - they only want your money by selling you closed source extensions.

I have already moved my 2 servers with 50+ million views/month to MariaDB and I am serving ~35 million views with single quad-core server (but of course heavy caching is involved).

Wink

I use XtraDB instead of the standard InnoDB. I serve 40 req/s med and 100 req/s top on a single server. It heavily depends on the patter of the visits.

Una curiosità per i più esperti:
la chiave privata è abbastanza sicura ? Quanto tempo si impiegerebbe per craccarla ? Se tutti si mettessero insieme con una potenza attuale di circa 300 petaFlops quanto tempo ci si impiegherebbe ?
Considerando che esiste amazon ec2 e quindi la potenza sarebbe disponibile da subito, dipende tutto da quanto costa.

Riusciamo a fare 2 conti ?

Ciao

I due conti non te li so fare, però ho un paio di informazioni utili. 1, non devi considerare la lunghezza della chiave privata ma dell'indirizzo pubblico. Più chiavi private possono collidere nello stesso indirizzo pubblico. 2, non è in flops che si misura la potenza di hashing. 3, gli indirizzi pubblici sono di 34 caratteri, il primo carattere è il protocollo e alcuni caratteri sono di checksum dell'indirizzo, quindi non so quanti sono i caratteri di entropia, ma considero che siano 30; 30^62 = 10^91.

La domanda ora diventa, ha senso eseguire le trasformazioni elencate in questa pagina, https://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses per un campo di ricerca di 10^91 (spannometricamente ci sono combinazioni da provare che atomi in tutto il territorio italiano) oppure è più remunerativo usare questa potenza di calcolo per minare bitcoin?

Per ora, conviene minare.

In futuro chissà.

25% of queries are delivered from the query cache, which seems pretty good.

Over last few years I’ve been suggesting more people to disable Query Cache than to enable it. It can cause contention problems as well as stalls and due to coarse invalidation is not as efficient as it could be.

25% of queries delivered from cache doesn't necessarily means better performances.

I don't know about how optimized the indexes are for this decade-old board, but i'm sure that you would see a huge benefit converting to a 2013 board (xenforo is my bet, IPB of VB if you wish) and using InnoDB.

Ciao,

Notizia molto interessante.

Potresti linkarmi un documento ufficiale in inglese su questa cosa? Non trovo dati sull'uscita dal corso monetario delle vecchie banconote.
3391  Bitcoin / Bitcoin Discussion / Re: Holy F***, what is happening? Most Users Online today since 1 and 1/2 Years! on: January 12, 2013, 07:29:23 AM
Is mysql query cache enabled? AFAIK it is disabled by default and can really improve DB performance.

You can check with a SQL query:
Code:
Show variables like 'query_cache_size';
(0=disabled)

Thanks, I'll try enabling that!

Disable it.

I have no words to describe how dumb its to enable the query cache on such a website. Every time there is an update to a table the whole cache is invalidated (removed from the ram). Every time someone access the website the new cache is created, to be invalidate one second after.

It's counter productive. It only works with websites with no/infrequent upgrades.

If you are tiny on budget (why the hell are you using softlayer/rackspace?) and you want to improve the database performance, convert everything to InnoDB and set innodb_buffer_pool to your free ram. I suppose that the free ram should be bigger than the size of the database. If not, buy a new dedicated. Even an ovh.com/us should do, you can buy 2 monster servers for the price you pay now and setup a failover to withstand "poor" hardware iusses.

I could do that for you, I enjoy doing these things, but I'm sure you wouldn't trust me enought. So please study and fix this.

I used that number as an example. I also just proved my statement, the forums on the Deepweb are bigger than this, and there are 100's of them. Even the biggest profitable section of this forum is illegal. At least for about 90% of the forum. Do you have any statements to back up why you think it isn't used for a large majority of illegal activities?
The problem of the proof stands to who brings up the theory - show me these deep web forums.

Anyway... Not to break the Avalon's Gold Eggs...

But where is the prototype scheduled to be released on video 20 days ago? 20 - 10 days of "possible delay" = 10 days without our video!

Cheesy

One feature request for the new forum that is critical for me: The ability to post/reply via email.
E.g. is the Google Groups interface.

I hate logging into the forum constantly to do these stuff.

(Dunno if this has been discussed or not)
Some 2013 technologies first, then, maybe, some NNTP-like stuff.


Does anyone know what it is that's forcing pages like "recent unread topics" to be a certain minimum width?
Don't know, i can resize it without any problem.

I agree. Miners need fiat for juice and hardware. Sellers of illegal good need fiat for food, clothing and shelter. It's far from obvious that a majority of bitcoin trades are for illegal goods.


There's a lot more illegal activity that Bitcoins are used for than you may think. If you explore the DeepWeb you'll see what I'm talking about. The people doing illegal activities are usually the ones making the most money, because, well, for one they're taking the most risk. They're taking advantage of risky services without the risk involved. It all comes back to the anonymity Bitcoin provides. If somebody wanted to sell 100M's worth of guns and drugs, there best option would be to use BTC, because it offers absolutely no paper trail whatsoever.

Except that you can't sell 100M of bitcoins. In every sense.

I don't think that you can prove your statement, anyway. It's just your tought.

Because you know, they did nothing on 11/9 and Bin Laden did not took responsibilities for that.

I'll lean the same way, and didn't even click the video (yet), for I'm sure I've already seen it.
It's a funny one, its worth viewing, whatever your position is.

Non capisco questo accanimento contro i contanti. Io sostengo i bitcoin anche e perché mi offrono delle libertà, libertà che con denaro elettronico tradizionale mi possono essere ristrette dalla sera alla mattina. Anche il contante offre queste libertà, in forma diversa ma non necessariamente peggiore.

Vengano i bitcoin, ma lunga vita al contante.
