61  Other / Obsolete (selling) / Buying BTC 20-1000 on: June 16, 2011, 05:13:04 AM
Looking to purchase BTC from 20-1000 using either Paypal Mass Pay or possibly Dwolla. Trusted ebay user (same user name) with 10+ year history. If interested PM offers and we can workout terms directly.
62  Economy / Economics / MtGox huge buy on: June 12, 2011, 03:42:30 PM
Watching the market history over the last few minutes it looks like someone executed a massive buy at $23 causing the system to backup as it filled all orders up to that limit. When it finally completed the order all of those that got hot to try and jump on starting pushing, it was hard to get something in but if you did it right it was a quick 20%.
63  Bitcoin / Mining / phatk vs. poclbm effective hash rate on: June 02, 2011, 10:38:38 AM
Like many others that have experimented I see an increase of about 5-10% in my reported hash rate when moving from poclbm to phatk.

On my 5770s running 935/1500

poclbm: 199 Mh/s 2011.beta4
phoenix with phatk: 207 Mh/s v1.48

I however noticed the reverse with my stats on deepbit:

poclbm: <400 Mh/s (varies lightly based on luck but always stays above 400 Mh/s)
phatk: ~375 Mh/s

To help account for variations I have deepbit average over 60 minutes and I've taken multiple samples to help account for the fact that deepbit will shift some depending on how fast a given set of shares are solved. The following questions come to mind:

1. Are the client values accurate with regard to Mh/s?
2. Is poclbm more efficient at managing the work queue and fetching/submitting shares?
3. Other factors?

I haven't done it yet but #1 should be able to be verified fairly quickly, in fact I assume if it were a problem it would have already been caught.
