1061  Economy / Trading Discussion / Re: SierraChart bridge - Realtime Bitcoin charts [v0.5] (MtGox, Intersango, ...) on: May 12, 2013, 05:42:33 PM
a separate question, please:
how can one avoid data gaps when not online? I am using the new bridge.

Also, how can one use the historical data and then continue with the bridge data. when I tried, it does not add the new data at all.

thanks you

I had the same problem! What I did was; I downloaded the mtgoxUSD.scid from here

SCID full history files:
from first trade 07/17/2010 23:09:17, to 04/30/2013 23:59:59 (UTC, tick accurate, precision 2):
(extract to C:\SierraChart\data\ before starting SierraChart) (18.2MB/182MB) <-- (8.2MB/86.4MB)

Then I made a new text file and named it scUTC.cmd. I edited this file with this
start sierrachartfeedUTC.exe --history=13
I used 13 because as of writing (12-5-2013) the last record in the mtgoxUSD.scid file is over 12 days ago. The default is 7 days, so it skips the 6 days before it creating the hole
Once you have all historical data, it does "opening streaming socket..."

I added the history command-line option, and set the default to just seven days, to discourage abusing the API server to catch up a full three year history by default. This also makes SierraChart useable for recent trade analysis in just a few minutes instead of hours or never.

When you start sierrachartfeedUTC.exe, it will resume downloading from the last timestamp, unless it's been over seven days since you last ran it (or if you are starting with my complete history file that's now 12 days old). The history option sets the maximum number of days back that will be resumed. If you have already downloaded the full SCID file or might not use bridge for over a week, you can then use the history option like above, setting it to 200 days for example, and it will still resume just where it left off when you last ran bridge (not downloading more data than needed).

I will update the history SCID download in a bit. This file is made with modified code that downloads history just to a certain checkpoint and doesn't pollute data with live stream, so it is a 100% true record of historical trades.

As of now, does Sierra works flawlessly with MtGox API or are there some problems?
This gets its data from; mtgox API doesn't have a feature to retrieve past trades.

"1bitcoin" was wasted on the bitcoineater, but I nabbed firstbits "1bitcoins". Somebody had to get it.
I could have waited until I found a better looking address, but it took long enough to find this:

You know that you can cut & paste from a console window, right? There is no need to post big repetitive images.

You should eliminate (or move into the next group) addresses that are alphabetically higher than 1QLbz7, as these are 58x higher difficulty, and can only be constructed with a 33 character address, equivalent in difficulty to an additional vanity letter.

You will also find success in using case-insensitive search by reducing the number of addresses down to ~5000-10000. A case-sensitive search starts at 260 times harder for a 10-character.

#vanitygen 1ABCDEfghij
Difficulty: 170408517192794400
[359.39 Kkey/s][total 276224][Prob 0.0%][50% in 10422.0y]

Difficulty: 654563965779613
[362.34 Kkey/s][total 455680][Prob 0.0%][50% in 39.7y]

I suppose I should also point out that the reason you see the error messages in the screenshot I quoted above is that you have lines that duplicate a shorter expression, such as I have demonstrated below:

#oclvanitygen.exe -d 0 -i -f 11-14.txt

Just trying out SierraChart now. I'm inexperienced and trying to figure out how to get data before <2011/06/26 for gox?

For some reason that's as far back as it goes. I used the "Bitcoin Data (MTGOX)" feed that came with the default install. I never tried the "MtGox Bitcoin Trading (under development)" option.

Am I doing it wrong? Smiley

It sounds like you are using the new Mtgox data direct from SierraCharts, and not the bridge. It may not have a complete history.

Try this:
1. Go to menu -> Chart -> Chart Settings, and set "Days To Display" to 1100 or more,
2. Set Bar period to 1-0-0 (1 day per bar),
3. Scroll to the left and see how far back it goes.

If they don't have older history, you can follow the instructions for using the sierrachartfeed above, using the mtgoxUSD SCID file, which has all history trades.

I'm down with adding a ripplescam signature, but I would write it a bit more eloquently. I think their medium-term plan is to get people to transfer them real money to fund their IOUs before they disappear, not just to have a 100% premine coin. Having that message in my signature would make my plan of disposing of those scamcoins on suckers/believers harder though Tongue.

Hello everyone,

So I am new to Bitcointalk, haven't felt the need to register (can usually find answers to most of my questions just by searching, although now that I am registered I will likely be getting more involved) but I recently became aware of Ripple via stackexchange.
Be aware that there was a flood of Ripple questions and answers on stackexchange, posted and answered by various sock puppets of opencoin, basically using that site as advertising. Take nothing there about ripple as anyone having a real question, nor interpret an answer being an honest one.

Yes cause they censored them, either conform to our standards or don't do business anymore.
You sure like that word. I thought I did too ... too bad you're well on your way to destroying its meaning.

What the heck are you talking about? How was anyone censored? Or are you just happily making up stuff? Sad
The only thing censored is by me hitting the ignore button on the OP and anybody else posting stupid stuff here. Plonk!
1073  Other / Beginners & Help / Re: Verification failed, check hardware! on: May 05, 2013, 10:05:30 AM
Yes, if you want a new driver to work, you can ask (with BTC) a miner kernel developer to rewrite the kernel you have chosen in guiminer to support whatever the newest driver and SDK has done to break OpenCL applications. This will benefit few, as dedicated miners already run the appropriate driver to give them not only working but the fastest hashing, and don't use guiminer.

This is the crux of the problem, your local blockchain database is corrupted and the client can't build on that. It doesn't have the intelligence to try to get the block 234410 again from the network and replace your screwed up version with the correct one.

You will need to delete the blocks and chainstate directories from your bitcoin data directory and attempt to resync the blockchain from the start. Typically this kind of random corruption indicates bad hardware, such as a bad sector on a hard drive or bad math from an overheating or overclocked CPU.
1076  Other / CPU/GPU Bitcoin mining hardware / Re: How many video cards can cool 3-4 Kilowatt air conditioner? on: May 04, 2013, 06:43:33 PM
The amount of heat generated by 1 kilowatt worth of computer (about four 200W video cards + system + 900W power supply inefficiency):

1kWh = 3,412 BTU

So we need 3400 BTU of A/C to remove that much heat generation.

The the next question is how much power will that cooling require. We must look at the the energy efficiency of air conditioning, which is typically given as SEER (seasonal energy efficiency ratio), which we must translate into an actual efficiency measure.

COP = 3.41214/EER

As a low-water benchmark, lets look at a 5000 BTU window AC unit ($110 on website)
Specs: EER=9.7, Watts=515 (calculated efficiency multiplier: 2.84)

So this particular model moves 1462W of heat with 515W. A central AC will be more efficient, so 3000kW * 2.84+ = at least 8000 watts (but nothing left to actually cool your house against summer temperatures).

Real miners don't use AC though, why reduce profitability? Put the units in a closed room with a window fan, or in the garage.
1077  Other / Beginners & Help / Re: Still a little confused on Wallets. on: May 04, 2013, 05:10:36 AM
Bitcoin gives you all you can eat addresses for free! Just put keypool=10000 in your bitcoin.conf file, now your wallet has 10,000 pregenerated addresses in it (you'll have a backup that never becomes obsolete).

There are 1461501637330902918203684832716283019655932542976 possible addresses. That's enough for 100x the world's current population to have 1826877046663628647754606040895353774 addresses each.

There will be a maximum of 2100000000000000 Bitcoin base units (a satoshi, or 0.00000001 bitcoin).
Even if every single base unit that will ever be created were put in a different address, there will still be 1461501637330902918203684832716280919655932542976 empty addresses. The chance of you generating an address that has a satoshi in it will be 1 in 695953160633763294382707063198230.

So in other words, it doesn't matter if you create lots of addresses and delete them. If you never use them, the network doesn't even know they exist.

Domains get hacked often. The problem is if someone hacked the domain registrar account and transferred the domain away, it may be a bit of work to get it back. It's 7pm on a Friday in Japan, 3am in the US. It will take time through the Transfer Dispute Resolution Protocol if the receiving domain registrar doesn't immediately hand it back on the word of registrar #1.
