if you use linux you can use the string command to take a look at ascii characters in the binary, there is a web site listed, however I do not know how it is related to the scam mining software.

302  Bitcoin / Mining / Re: pushpool - open source pool software on: June 29, 2011, 11:22:40 AM

Under Centos 5.5 when compiling pushpool 0.5 I get this errrors:

/root/pushpool05/pushpool-0.5/msg.c:562: undefined reference to `htole32'
server.o: In function `cli_send_hdronly':

collect2: ld returned 1 exit status
make[1]: *** [pushpoold] Error 1

Can someone define htole32 and le32toh since they are not part of ansi C, and therefore fail to compile under Centos 5.5 using gcc 4.1.2

Thanks

Yes interest rates with bitcoins are possible, you could have a bitcoin bank.
Having a bitcoin bank would require some sort of guarantee that you get paid back, and as such there is a risk involved.

The difference with bitcoins assuming a risk of 0, with very little interest you could make a profit, unlike inflationary currencies were you have to cover for inflation, but in real life the risk is not 0, so some interest would be needed for a loan otherwise you would have loses.
304  Bitcoin / Bitcoin Discussion / Re: Shift the decimal point over? on: June 27, 2011, 09:39:38 AM
Very bad idea to shift to 6 decimal places.
From a mathematical point of view it makes no difference.

But from a press point of view it will make it look like there is hyper inflation, not good.
You do not want the average person to start comparing the bitcoin to the zimbawen dollar.

It is much better to use the proper term, microbitcoin 1/1000000 or milibitcoin, for 1/1000 if the value of the bitcoin goes up, or simply just use decimals, after all most transactions are online.
 
Bitcoin it is a currency anti inflation, and it is best to reflect that fact.

Use Linux, and take additional steps for added security.

Windows is insecure by default, to many viruses available, and not one antivirus is 100% perfect, they all have a margin of failure were new viruses go undetected.

There are also viruses for Linux but it is very rare, and Linux out of the box is more secure.

What everyone should do is run Linux, Debian (Ubuntu), Fedora, Mandrivia, etc.

And for those of you that have a lot of bitcoins encrypt and backup the wallet.
pgp, gpg, and best crypt, true crypt are all good choices.

True crypt is best for usb, or portable disks.
pgp or gpg are good for encrypting the wallet directly.
or in you want something transparent with best crypt you can configure an account to automatically mount an encrypted file system, once the file system is mounted it is no longer encrypted until you log out, so best crypt works best using a separate account that you log in, and as soon as you are done log out, once you log out the filesystem is unmounted, and it is an encrypted folder representing the filesystem.

The only problem is that if you are expecting a payment you can not have the wallet encrypted with the current version of the bitcoin client, therefore what you can you is use 2 accounts, one that keeps the wallet encrypted and you backit up, and the other that you use for receiving or making payments, after  that wallet reaches certain amount of money make a transfer to the wallet you keep encrypted, and then backup the wallet in encrypted form somewhere else.

That way you have 2 wallets, once for pocket change, like the wallet you carry in your pocket un encrypted, and the other wallet that has all the cash encrypted and backed up.

Also when using encryption use a secure algorithm, there are many that are very secure, and others are very easily broken.

Also when it comes to encryption always use an open source package.
There is an old saying that security by obscurity is snake oil, so rely on open source for your security.

Another reason for using encryption if your computer is stolen, with either windows or Linux it is possible to log on the system once the thief has physical access to your machine, however if the wallet is encrypted there is nothing the thief can do other than a brute force attack, and if you used a secure password with a good algorithm it is nearly impossible for the thief to gain access to the data in your wallet.
306  Bitcoin / Bitcoin Discussion / Re: My account request was rejected by MtGox - what should I do? on: June 24, 2011, 05:15:07 AM
Lets hope that all the accounts are active before they open up.
Otherwise it is going to suck big time for the ones that do not have the accounts ready.

Mtgox should make a guarantee to everyone that the accounts are ready before they open for business again.

I do not have my account ready, and have no clue when it will be ready.

I was told to reclaim my account again, and it is not working because I already had reclaim it, and was told to wait for a manual confirmation, but on the support ticket system I am told to check for updates on www.mtgox.com.

Are there a lot of persons having the same problem?
307  Bitcoin / Project Development / Re: [v4.1.2] Mining Farm ::: Annoying Bugs Sqwished! on: June 24, 2011, 01:22:41 AM
bug reports based on demo, which I believe it is 4.1.2 since I could not find the version number on it.

Under account details --> worker Status it displays
{ "User":{ "username":"sergio.3", "currSpeed":"0", "status":"Connected" }, "Pool":{ } }

CurrSpeed:0 it seems wrong since the miner it is running.

Under account details --> Overall Stats
The requested URL /json/poolstats.php was not found on this server.
The file is missing.

The estimated reward for the round seems to be off, since I am the only miner currently running the test and as time goes by the rewards goes down, that would make sense only if there were more miners joining the test.

Under Managed Workers, once a worker has been created the delete option does not work.

Hopefully this bug will be fixed on the next release.

Thanks

Alguien tiene noticia, de cuanto demora el proceso de verificacion de mtgox?

yo ya inicie el proceso de verificacion, pero falta la parte final en donde finalmente te puedes logear a tu cuenta.

Si alguien sabe algo por favor informar aqui.

si estas trabanjo en un bloque y otro minero lo descubre y reporta primero el se lleva el bloque.

Eso de tiempo perdido es cosa de como quieras interpretar tu las cosas:

Por ejemplo si lo tomas como tiempo trabajado no es tiempo perdido ya que durante el trabajo existia la probabilidad de descubrir el bloque, pero si usamos una deficion similar al lenguange de calle, como no se encontro nada durante ese tiempo, mucha gente condideraria esto tiempo perdido, pero si tomamos en cuenta que para encontrar algo es necesario perder el tiempo por la ley de probabilidades, entonces este para un minero no se deberia de considerar como tiempo perdido. La analogia al oro applica aqui, tu entras a una mina a sacar oro y un dia sales con nada, y te preguntas si se realizo trabajo, bueno muchos te dirian que si ya que al intentarlo tenias la probabilidad de encontrar el oro, otros te dirian como no encontraste nada entonces perdiste tu tiempo. Mi opionion es que si realizas un trabajo mientras la probabilidad de este sea superior a cero as hecho un trabajo y no as perdido tu tiempo.
311  Local / Español (Spanish) / Re: mtgox.com ha sido hackeado on: June 20, 2011, 10:57:46 PM
Lo que no se sabe aun son las perdidas totales que pudieran haver.
Ya que es possible que en dolares los crackers solo pudieran robar la cantidad de $1000, es posible que en bitcoins la cifra sea muy superior, ya que segun tengo entendido no hay limites en las retiradas de los bitcoins.

Una  buena idea que escuche que van a implementar es la de otra contrasen~a para retir dinero de mtgox.

La gente tiene falsas idea de seguridad por ejemplo limitar los intentos de logeo es bueno, pero poner un numero de intentos de 1 o 2 logeos es mala idea, ya que es bueno motivar el uso de claves largas, por otro lado si no hay control de intentos de el logeo en un par de segundos se podran hacer miles de intentos de logeo y eso es malo.

Unos 5 intentos de logeo, con un tiempo de demora de unos minutos en caso de falla de clave seria buena idea, despues de todo ningun cracker va a esperar 10 minutos por ejemplo para hacer solo 5 intentos, eso seria un intento por cada 2 minutos, en cambio sin medidas de seguridad se pueden hacer miles de intentos por segundo lo cual es malo.

si la cantidad de intentos se limita a un intento esto es malo, ya que habra una tendendia a usar claves simples que son faciles de craquear a fuerza bruta.

It would be a good idea to investigate what role has the windows os been playing with all the recent security problems with bitcoins.

It would be a good start when dealing with bitcoins to use Linux a much more secure operating system than windows, there are other OS that are also very secure such as OpenBSD, FreeBSD, etc.

Mcfee announce recently the first virus to steal wallets, but it only runs on windows, so In general Linux is a lot more secure.

It is very common to see a so called security expert use a windows computer, online security it is important, and such tools that provide that security should be used.

Windows itself is very insecure.
Linux is much more secure, and can be made more secure by the admin.

The ratio of virus in the windows world vs the linux world is huge, linux has less than 1% of total viruses that exists.

Hopefully the mtgox problem gets resolved soon.


313  Economy / Marketplace / New site offering VPN SSL VPN service in bitcoins, and VOIP on: March 29, 2011, 07:02:18 AM

The site is www.vpn3000.com
The price is the lowest on the market.
$40 USD  per year, or $8 USD per month.
We are giving a promotion for payments in bitcoin, 5% off, or 10%off if you identify the phone on the site.
We convert the dollars to bitcoins at market value.

For VOIP, I will give 5% off for bitcoin users, the way the 5% off will work, is that after we convert the bitcoins to dollars I will add 5% to your phone credit.

As far as voip goes, we support IAX, and SIP, and resale of voip  service.
Very low rates, no monthly fees for voip.

Has someone had trouble with the site https://en.bitcoin.it/wiki/Trade#VoIP since I have posted we web site there 4 times and ti always gets deleted by someone, this last time I posted it 3 times, to make sure it is getting deleted on purpose.

Has anyone had trouble of their postings getting deleted from the site: https://en.bitcoin.it/wiki/Trade#VoIP. could it get that someone does not like the competition?

The site vpn3000.com is all open souce software, for the vpn and voip, the site may look simple but it is all open source, and compliant with most web browsers.
