181  Bitcoin / Bitcoin Technical Support / Re: How 'Anonymous' is Bitcoin? on: October 22, 2014, 02:18:21 AM


Is it secure enough? I lost 1 BTC using blockchain + TOR (a few days ago) and 1 BTC using coinbase + TOR ( a few months ago)

I used them as hot wallets, while the rest of the BTC were, and still are in a cold wallet with Armory.

What was your client for the hot wallet that you lost money in?  What brand? How did you lose the money?  Keyboard logger?

All nodes on the network are equal and automatically assume 100% that information received from connected peers is malicious until independently verified by itself.
This is the cornerstone security model of the bitcoin network.

Any data received from a peer node containing invalid data (deliberate or by accident) will be ignored.


Yes, I agree, most of the time this is true.  But see this post below and consider the implications if the "canonical" blockchain had bit rot during this critical moment.

"Adopt this blockchain, it is the best one" and they are trustworthy, and people adopt it, but the blockchain has bit rot?  Anyway I'm not going to worry about it, it's not my job.

Thats not how bitcoin works. No full node just trusts another node. Most of your threads I read in the recent past could be avoided if you read the whitepaper.

You make an ad hominem argument, in an attempt to sound authoritative ("most of your threads"), a common rhetorical tactic.

Educate yourself and get back to us (note the royal plural) by reading this thread, pay attention to the quoted language:

Tony we've got same house edge of evry other dice site Wink
Please let informed before speak.

If you don't like gambling why you are in this forum section?  Huh

Why do you say I don't like gambling?  I play poker with friends all the time.  You are clearly Russian, as you speak in accusations, as is common in that country.  Also you are the front man, meaning the people who really built and backed your site are invisible.  Why they chose you, who speaks and writes badly in English, is a mystery, but possibly it's a very small group (probably relatives) and you are the only one that speaks passable English.  Anyway, as I say I wish you luck--you will need it.  I see you are hosting with GoDaddy, which is not my first choice for anonymity, as they will kick you off as soon as anybody complains (it won't be me, as I don't care what you do).  I bet you are in Russia however, where nobody cares about illegal gambling.  

Good luck!

http://en.wikipedia.org/wiki/Data_degradation ("Data degradation in memory can occur when the small electric charge of a bit in RAM disperses, possibly altering program code or stored data. The hypothesis that semiconductor RAM may occasionally be altered by cosmic rays[2] is also known as soft error.")

Private keys can be subject to bit flip errors, so individual wallet can lose coins if there is no backup to restore the wallet from. As for the rest, the network is embarrassingly resilient (faulty node is no different from evil node).

Thanks for the answer.  Well that's nice, but with Google, they did have RAID and apparently that was not good enough.  Let me find the article... no, I could not, but LOL I actually see this thread is already indexed by Google, so let's stay on topic and be nice so posterity can benefit from reading this...  the best I could find is here: http://serverfault.com/questions/77710/is-bit-rot-on-hard-drives-a-real-problem-what-can-be-done-about-it

So in a RAID system, where there's all kinds of redundancy, you can have bit rot that creates problems. So why not also in the Bitcoin peer-to-peer network?  I think it's possible, if somebody says: "Adopt this blockchain, it is the best one" and they are trustworthy, and people adopt it, but the blockchain has bit rot?  Anyway I'm not going to worry about it, it's not my job.

Tony i think you don't know what is house of edge.
House edge !=% Site profit.
House edge is a mathematical percentage number achievable with the percentage of winning bets.

Example.
If you play with payout 2.000 you have 49.50% Win Chanches, the Site Win Changes is 50.50%. So, our site have got 1% house edge
Do you understand?

From your site:  Payout: 1.980 X <=50.00.  So, on average, I lose 2%.  Is that standard with the other 'dice' shops?  If so, I see your point.  But if not, you are too expensive.  Anyway good luck, you'll need it.  If you get caught, the police in your country may ask for either a bribe, or, if they are European, will fine you and take away all your profits, maybe even jail you.

No 10965 is testing your site for random play.  He/she/it does not believe in the 'provably fair' stuff and wants to see if in fact the odds are fair.

10965 is welcome, I hope he can post the results of his test so you stop saying that it is not fair  Grin

I never said it is not fair.  What is your first language?  I speak several languages, maybe I can post in Russian for you?  But here's what I found about your site:  your payout is 98% on a 50% roll of the dice, meaning you (the house) takes 2%, whereas everybody else on this site:  http://bitcoindice.com/  only takes 1%

Why should we pay you twice what the other dice sites take?  What is so special about you?  That you have stock photos from Google Images of bikini models?  Please...do you think people are that stupid?  You don't even have live models.  I guess you believe, like PT Barnum, there's a sucker born every minute?  And sadly maybe you are right.

How many bets made 10965?

About 1800 in 50 min.

Hey 10965, if you read us, do you need developer api? ^^

It seems to me 10965 was betting mostly  0.00000000 BTC.  Why is this allowed?

Now 10965 is back!  Driving all the other users to the sidelines--why?  Why when 10965 plays, all the other IDs disappear?  {Edit:  OK they don't disappear but they seem to diminish}
190  Other / MultiBit / Re: Soooo I have $100 stuck in my wallet on: October 21, 2014, 06:41:24 PM
I have a multibit wallet I created a few weeks ago and fat fingered the password after I transfered the bitcoin I found that out! I tried every password I could think of and then some..  Embarrassed I assume there is no getting it back?

That's the problem when they don't have a "show password" checkbox.  If you make the same mistake in typing the password twice, you're hosed.
191  Economy / Gambling / Re: [ANN] BikiniDice is launched! on: October 21, 2014, 06:04:53 PM
As of this moment, your web page shows one user "10965" making all the bets.  Does not look good to me.  Who is user 10965?  is that a bot?  Where are the real people?

Anyway, good luck, since to be honest anybody who gambles is just looking for a pleasant experience while they lose their money, either slowly or quickly.  I would however use non-stock photo bikini models.  Aren't there any real models you can use from Ukraine or somewhere?
192  Bitcoin / Bitcoin Discussion / Re: PAYPAL FOUNDER PETER THIEL: “BITCOIN IS THE OPPOSITE OF PAYPAL” on: October 21, 2014, 05:52:46 PM
LOL why does Thiel use heroin as an example?  I would think pot is more common.  Sounds like he's trying to scare people.  Also wasn't he a founder of PayPal?  Yes.  So he has a vested interest in keeping his pals at PayPal happy (I'm sure he has friends there, even if he sold his stock).
193  Economy / Services / Re: Offering Programming/Scripting on: October 21, 2014, 05:49:50 PM
I suspect that until you can prove that you can actually write code, nobody is going to be interested in your services. It is going to be very difficult for you to find work without proof.

Some clients who hire developers don't want their work product being shown to others; I would think this is the rule actually for most clients.  At best you can just use their name and say "I worked on building this project ABC at client XYZ".  That's why Google etc wants a face-to-face interview or at least over Skype so they can ask you their infamous programmer's questions on the spot.  But the OP is making an interesting proposal: if you don't like my work, don't pay me.  Haven't seen that before.
194  Bitcoin / Armory / Re: Does Armory take a long time to synch up for you when you start it? on: October 21, 2014, 05:44:54 PM

That does not seem right.  It takes around half a minute to a minute for me if I just stop Armory and let it restart.  Perhaps you have a very slow harddisk or very little RAM, perhaps there is something else wrong.  But something clearly is wrong.  Have you tried looking at the log while it starts, maybe that can be an indication of what is wrong.

Where is the log file?  If it's in the menu or somewhere obvious I will find it.  I doubt my HD or memory is at fault, though I am pretty sure that if I switched to an SSD (as I might for other reasons) no doubt the entire process will be sped up considerably.
195  Economy / Speculation / Re: Wouldn't it be nice... (the LazyWhale algorithm) on: October 21, 2014, 05:41:20 PM


Interesting paper, didn't know it before. Thanks.

You know... the cool thing about the EMH (weak or strong, doesn't matter) is how easy it is to empirically falsify it. Just one factor, in one market that yields a result above the significance cutoff (maybe even adjusted for unpublished results Cheesy) is enough to at least declare the EMH for that market dead.

So, if you don't mind, I'll add a link to your paper to my canned response in the future:

Quote
To see how the new t-ratio benchmarks better differentiate the statistical significance of factors, in Figure 3 we mark the t-ratios of a few prominent factors. Among these factors, HML, MOM, DCG, SRV and MRT are significant across all types of t-ratio adjustments, EP, LIQ and CVOL are sometimes significant and the rest are never significant.

So you just make it up as you go along, or did you run the factors through a stats filter?  Re EMH, your empirical falsification would be Warren Buffet of course...

Good luck and let us know when it is open season to insult you... I'll be watching this thread. ;-)
196  Other / Politics & Society / Re: Anyone following the ebola outbreak? on: October 21, 2014, 05:14:29 PM
Good recent article on Ebola here: http://www.newyorker.com/magazine/2014/10/27/ebola-wars

Doctors and other health workers in West Africa have lost track of the chains. Too many people are sick, and more than two hundred medical workers have died. Health authorities in Europe and the United States seem equipped to prevent Ebola from starting uncontrolled chains of infection in those regions, but they worry about what could happen if Ebola got into a city like Lagos, in Nigeria, or Kolkata, in India. The number of people who are currently sick with Ebola is unknown, but almost nine thousand cases, including forty-five hundred deaths, have been reported so far, with the number of cases doubling about every three weeks. The virus seems to have gone far beyond the threshold of outbreak and ignited an epidemic.

[incoherent rambling about EMH and markets]

Here, have my canned response for cases like this:


Your canned response always includes an insult too?  How thoughtful (Not).

Although I doubt you will understand it, here is a paper [1] you should read and ask some grownups what it means.

Good luck with your market crystal ball gazing.  I expected to see a plea for donations for your so-called research, but happily I did not see you stoop that low.

[1]
http://www.nber.org/papers/w20592

Hundreds of papers and hundreds of factors attempt to explain the cross-section of expected returns. Given this extensive data mining, it does not make any economic or statistical sense to use the usual significance criteria for a newly discovered factor, e.g., a t-ratio greater than 2.0. However, what hurdle should be used for current research? Our paper introduces a multiple testing framework and provides a time series of historical significance cutoffs from the first empirical tests in 1967 to today. Our new method allows for correlation among the tests as well as missing data. We also project forward 20 years assuming the rate of factor production remains similar to the experience of the last few years. The estimation of our model suggests that a newly discovered factor needs to clear a much higher hurdle, with a t-ratio greater than 3.0. Echoing a recent disturbing conclusion in the medical literature, we argue that most claimed research findings in financial economics are likely false.

The hypothesis that semiconductor RAM may occasionally be altered by cosmic rays[2] is also known as soft error.")

A while ago --within the last two years I think-- Google claimed that one bit in a server farm rotted (I vaguely recall this is a 1 in a 10^12 event, but if you have enough bits it's possible), and this error somehow propagated and crashed their entire network.  Given this was Google who hires the best talent money can bribe, I wonder what would happen if somehow the BTC blockchain, if there is a canonical or gold standard version somewhere, suffered data rot, let's say a solar flare produced lots of cosmic particles that caused an error?  Would the entire BTC ecosystem come to a screeching halt?  If it happened to Google, it can happen here?

I'am personally using Electrum for the moment , and I don't know if it's that good.
and about where do I live , well I live in Algeria . and it's one of those countries where they use only Cash . (no paypal , no bitcoin , no skrill .. not even credit & debit cards).

LOL I've been there, done that.  Not Algeria but close enough.  Not to get too far off topic, but why don't you like Electrum?  Have you tried Multibit?  It seems so far easy to use.

Campbx is fading away and have multiple issues. Should probably remove from your list.

ok, I had deleted it.
if anyone foud another bitcoin exchange, I will add it

campBX is based in US, at least not gone away.

coinbase should be added to the list, for US people who don't care too much about privacy (or who plan to wash their BTC later anyway).  Coinbase also has a bad reputation when prices jump up or down; it is said they will cancel your transaction, but so far I've not heard them take anybody's money illegally.
