Re: SierraChart feed/bridge reborn - Realtime Bitcoin charting

There is no guarantee on the order of the data so you'd need to sort it in some cases. Sorting can be done in O(n log n) so it shouldn't be a huge problem. I'll consider pre-sorting on the server in the future but please don't rely on it!

The reason for the unsorted output is likely that I've switched to a database backend that can run things in parallel now or maybe it just went unnoticed until now for some other reason.

Crossed orderbooks are completely natural on exchanges like bitcoin.de and localbitcoins due to manual order matching done by the users -- not automatically by the exchange!

Provider (Hetzner) messed the routing up. I couldn't even reach the server and the support didn't understand the problem ("Ping works fine so your server is up").

The site you saw seems to be served from 176.9.79.205 while bitcoincharts.com is 176.9.79.196.

Complete dumps (updated once a day) are now available from bitcoincharts:
http://api.bitcoincharts.com/v1/csv/
This is a beta feature and might change without notice.
Is it tick data? Starts from 26.05..
Doesn't look like from the very beginning..


Where did you get that 26.05 from? It's the complete history.

CC Licensed photos of people using Bitcoins?
by

on 27/03/2013, 06:55:42 UTC
Hey,

I'm looking for CC licensed photos showing people using Bitcoin. Please post URLs (with license and copyright information!) if you have made such photos. I intend to use them on bitcoin.org as background images.

Things I have in mind:

* Smartphone used for transaction
* "bitcoin accepted here" sticker on door (no brand names should be visible)
* a pretty map of the world showing transactions
* physical coins, bitbills, ...
* ...

Re: client command line option -wallet= in addition to -datadir=?

Patch here: https://github.com/tcatm/bitcoin/commit/126fdaef110aca47acf888a2e599167554280fe7
Branch multi-wallet: https://github.com/tcatm/bitcoin/tree/multi-wallet

It allows to select between multiple wallets within the datadir. e.g. bitcoin -wallet=foo.dat will load $DATADIR/foo.dat (or create it if it doesn't exist). Don't use it to access wallets outside the datadir.

Try http://bitcoincharts.com/charts/mtgoxUSD and click "Load raw data" (below the chart). It'll show you a table with the same data (+weighted price for each interval) as is shown in the chart.

The chart viewer at http://bitcoincharts.com/charts/ will now display the raw data used to render the chart in a table below.

(I've got tons of emails asking for raw data...)

Re: Bitcoin v0.4.0 (Linux) stale connections handling

IIRC the problem is because your router is not closing those TCP connections correctly so as far as bitcoin is concerned those connections are still open.

Yes, it's the total number of bitcoins generated; not the number if bitcoins "available".

Maybe you can ignore merges when counting number of commits, as these rarely contribute code themselves?

I'm using github's API: https://github.com/api/v2/json/repos/show/bitcoin/bitcoin/contributors/anon

Looks like someone did that and it now includes people who didn't contribute a single line of code to the satoshi client (which the little box is all about).

Live at http://188.138.99.158/ (hopefully soon on bitcoin.org). It's updated daily via a cronjob.

Source code: https://github.com/bitcoin/bitcoin.org

Feel free to make pull requests to improve it. You can even extend it with jekyll plugins.

I recently created this chart http://i.imgur.com/sotmB.png (y: seconds, x: blocks)

Maybe it's something you could add to your site? It might be useful to detect irregular timestamps.

I have this feature in my development branch and I'm going to push the changes to bitcoin.org within the next days.

Here's a screenshot. Should I have missed any aliases let me know and I'll add them.
