1061  Bitcoin / Press / Re: 2013-04-26 CBC - Revenue Canada says BitCoins aren't tax exempt on: April 28, 2013, 05:45:55 AM
"Barter transaction rules apply where BitCoins are used to purchase goods or services," Canada Revenue Agency spokesman Philippe Brideau said in an email."
...
"But as the CRA statement shows, governments are starting to pay attention."

So the reporter emailed for a comment, was pointed to existing 1995 rules, and concludes that governments are "paying attention"?

Joo got scooped:
http://www.huffingtonpost.com/john-pavley/miner-mike-the-bitcoin-mi_b_3171118.html?utm_hp_ref=technology

"Bitcoin fixes Blizzard's World of Warcraft gold mining?" Really?


The emphasis of any article these days should not be on mining, except mentioning that it's completely pointless to mine unless you want to put thousands of dollars into capital and have a sound plan to obtain a solid ROI; that the currency is best obtained by and used for commerce. The mistake reporters make is to rehash what has already been written many times about Bitcoin filtered through their own noob misunderstandings.

Every article about what shirt Miley Cyrus is wearing today doesn't have a background on who she is, where she came from, how many records she sold, along with interviews of the "weirdos" who are fans and editorializing from the writer about how she isn't a legitimate artist. You can't report on just what Bitcoin is, because it was news two years ago; if your beat is Bitcoin, go find some news.

as long as you see continuing block downloads, everything is fine. The number of blocks remaining is obtained from a calculation of the most recent block number from multiple peers - if you don't have enough peers for consensus, or one is sending you bad data, then Bitcoin will use block 216116 as the best height in it's display calculations instead.

Alright I got this scumbag!He replied back to my second email address. Any recommendations on what to do now?

Send him an email asking please for a refund, as you see that ASICs won't ship for a long time. But first go to spypig.com and get a tracking image you can put in the email you send so you can get the person's real IP address.

Thanks for that, I got his IP, his location, the type of computer and browser he is using. He is in Wisconsin. So what should be the next step? Should I report him to the police or something?
There are websites where you can see if the IP address is a Tor exit node - if it is, then the information is useless. You can at least use the information to more forcefully demand a refund.

bitcoincharts is alive again.

Every attempt I make to download the whole history, it often gets through a month or two but always ends up crapping out with a 502 error.

These errors persist even with the rebirth of bitcoincharts. They seem completely random, with no relation to the amount of data or the amount of time since the last request. I can wait five seconds between requests that are 1/20 the size of maximum and they still randomly happen. Of course the bitcoincharts API overview does say "Don't query more often than once every 15 minutes!", but that would make getting any amount of history beyond a single request take forever.

Therefore I have tried to make code that figures out what bitcoincharts wants and only gives up if it has way too many 502 errors. It slows down and requests less data upon errors to reduce hammering the server:

I made it work with the latest drivers and cgminer, just answer the default questions, and you'll soon be on your way to making less than one "minimum transaction fee" in BTC per month.
1069  Bitcoin / Mining support / Re: What do I buy and/or install to get started? on: April 27, 2013, 01:52:31 PM
I'm very confused as to why a senior member with nearly 300 posts is asking the most basic question possible?

"Empty vessels make always the loudest sound; the less virtue, the greater report. Deep rivers pass away in silence ; profound knowledge says little ; but what a murmur and bubbling, yea, sometimes what a roaring, do they make in the shallows ! The full vessel gives you a soft answer, but sound liquor. Samson slew a lion, but he made no words of it: the greatest talkers are the least doers. As when a rabbi, little learned, and less modest, usurped all the discourse at table; one much admiring him, asked his friend in private, whether he did not take such a man for a great scholar: to whom he plainly answered, For aught I know he may be learned, but I never heard learning make such a noise."

So that you can see your original and only question is clearly answered, end of thread:
Is anyone familiar with the 8800 GTS in regards to mining?
Yes.
1071  Bitcoin / Technical Support / Re: Running programs written in Python on: April 27, 2013, 01:30:14 PM
I would suggest that if you don't have the skill to read arbitrary code from the Internet and understand it, especially if the author is targeting Bitcoin users, that you do not run such code on your computer - it could as easily have obfuscated "upload wallet.dat to hacker" code.

The code snippet you linked is for executing a trade on btc-e, you must do more than just click on it, it requires your api key and secret key be added to the code, and you must use command-line parameters to specify what currency and type of order you wish to execute. It says that on line four of the code. Original thread: https://bitcointalk.org/index.php?topic=97359.msg1075244#msg1075244

All that is needed is to download and install Python. For Windows: http://www.python.org/ftp/python/2.7/python-2.7.msi

The code only requires standard libraries, but you may find other advanced code that require other common-but-not-included libraries, such as greenlet, twisted, zope, boost, etc.

Here is some code which takes command line options; try saving this as example.py and running it from the command line. Master this first:

import sys; print ' '.join(sys.argv)

I've got one, it rips out a considerable 14MHash/s, which is enough to earn 1 BTC in approximately never.

anyone else seeing the error message about mysql server failure using deepceleron's exe?

if so, anyone got a clue when it'll be sorted?

if not, uh... help?
All of http://bitcoincharts.com is currently down (the source of Sierrachartfeed data), replaced only with "Our MySQL server started to fail this night. We're migrating to postgres now, but this will take some time." This is a first in two years. This may also create a gap in history if they don't have a separate grabber, so anybody else that has some alternate mtgox API logging, KEEP IT GOING so that bitcoincharts can resurrect any missing data!
1074  Economy / Trading Discussion / Re: SierraChart bridge - Realtime Bitcoin charts [v0.5] (MtGox, Intersango, ...) on: April 26, 2013, 04:11:59 PM
on SC data feed since the data is properly formatted and you can use tick charts for example the only problem is they dont have data since day 1

With the exe version I just uploaded, data should be tick-accurate, although you need to set chart display appropriately (apparently the SCID can't set appropriate defaults).


Permanent fix for tick (adjust appropriately for other exchanges):
Go into Menu -> Tools -> Chart Settings. Pick "Edit Global Symbol Settings". Choose Service "SC Historical Data", and press New. Then edit on the "General" Tab:
-Symbol: mtgoxUSD
-Price Display Format: .00001
-Tick Size: 0.0000100
-Currency Value Per Tick: 0.0000100

Now in Menu -> Tools -> Chart Settings, "Price Display Format" and "Tick Size" is auto set to  ".00001"

Temporary Volume Fix until next SierraChart Launch:
Go into Menu -> Tools -> Chart Settings. Go to "Advanced Settings 2" tab and change "Volume/Open Int. Multiplier" to "0.01". Press Apply

See volume:
Menu -> Analysis -> Studies. select "Volume" and press "Add>>", and OK.

Looks like:


Bar analysis
Go into Menu -> Tools -> Chart Settings.
Set Bar Period to "Number Of Ticks", "Range Of Ticks", set the number, and do whatever analysis you want.

I wonder if there is any way to get Sierra Chart to display Level II data like: Orderbook and Sales

For daytrading it is quite important to receive the most actual tick data possible. I was comparing the chart display on MTGOX USD to the chart @ http://bitcoin.clarkmoody.com/ and I had the impression it was lagging behind that website. I wonder which feed is more up2date: the one from bitcoincharts or the one SierraChart is feeding?

I just logged trade times vs actual UTC time I received them on my computer (I have sub-1-second accuracy using NTP). Here are the results:

The average delay time is 15 seconds. If you use clarkmoody, it gets its trades to your browser directly from mtgox websocket; you can compare it's console and see that the bitcoincharts data is pushed in approximately ~30 second chunks (which is adequate for charting 1-minute intervals, there is no trading in bridge-connected sierrachart).

I might take a look at getting data from MtGox again, which is how SC is getting their feed (but how much do they delay?...). It was the original method, but was switched due to problems:

Version 0.4 released, fixes non-working streaming from MtGox. It is now using socket interface to bitcoincharts instead of MtGox's socket.io.

Pros - sierrachart now supports live streaming of all bitcoin charts, not just MtGox.
Cons - there's currently implemented only polling between bitcoincharts and mtgox and chart updates are delayed 5 seconds in average. But tcatm is working on socket.io support on his side, so it will gets better soon.

Enjoy! :-)

So you sent your money to someone you never met, over an anonymous payment network? You can contact law enforcement, but even if you said you said you wired $5000 of real dollars with Western Union to a Nigerian Prince, there isn't much they can or will do. The won't even go bust someone who stole your cel phone when you have their GPS location and a picture of them.

Search Google to find other scammers (selling a preorder for bitcoin payments only, no phone number, etc):
site:craigslist.org asic bitcoin

The highest likely IP address is http://www.speedguide.net/ip/184.5.139.15 , a Centurylink in Charlottesville, Virginia, however the other two payments that have been sent from the address have had relay connections in England and Germany, so the person likely knows how to anonymously scam.

This has happened so many times, I'm really shocked it's still happening. You shouldn't be using Paypal for Bitcoins - ever.

Paypal is not to be used for digital goods -- their de jure rules, our de facto rules. She may not have even claimed fraud, but Paypal may have reversed the transaction because you broke their rules (probably eBay's, too) and don't consider the transaction valid.

What was in the email Paypal sent you?

We've concluded our investigation into the transaction detailed below.
*snip*
What did they send before that? Generally, they'll have someone personally oversee cases and give you updates.

feedback was positive on ebay....paypal and ebay are huge scammers
Sellers cannot leave negative feedback even on the most scummy thieving users - they disabled that because bad feedback on criminals makes for a "negative user experience". eBay universally screws the seller, since the seller will always be easier to get money from (even by sending to debt collection if you withdrew the money) than the criminal using a hacked account, and then they take away the feedback ability that would make eBay look like a scammer's paradise for doing this.

eBay used to be just about collecting exorbitant fees on money and merchandise they never touched (and just let people leave honest feedback), Then they got into the PayPal business (so they could move money around in their system with 3% friction until it is all theirs), but then they realized that they couldn't let themselves eat the cost of fraud.

Every attempt I make to download the whole history, it often gets through a month or two but always ends up crapping out with a 502 error.  This is in Win 7 Ultimate 64.  Tried running as admin, increasing the buffer and running in XP SP3 compatibility mode all to no avail.

I can't make bitcoincharts not go down. http://www.tomshardware.com/forum/237521-49-what-gateway-error
Is there a particular exchange/currency that it is always getting or date you never get past when you see this error?

The history download will continue where it left off when the bridge program is restarted - the program SHOULD stop if it gets website errors, otherwise it will skip history downloading and get the live trade stream. After the live ticker data is added to the database with the current date and time, you will never get data older than that.

trying out the new feed from deepceleron. looks to be good. it's currently grabbing the history for me. to make sure i'm doing this right:

for the windows exe, the multiple exchanges option should look like this, right? "sierrachartfeed.exe -s mtgoxUSD,bitstampUSD,btceUSD"


There should be no space between the -s and the option.

You can also use sierrachartfeed.exe -s* if you want to download EVERY ticker, which is about 40 of them.

For those of us lacking programming expertise, is there a compiled version incorporating the recent changes discussed here? TIA.
Yes. 10 posts back.
