tl; dr; but if you are considering changing technology be sure to check redis. I love memcache but I wouldn't like my shares to stay just in memory.

Assuming btc dollar parity I was thinking like ~1200BTC. Of course it may end up higher (or lower) depending on offers. If you have just one card to sell, I may also be interested (especially if there will be second seller like you).

More exactly to Poland. Please send me you offers here or in PM including shipping (ideally some fast one, UPS seems ok). I pay in bitcoins, before shipping. We may need some escrow if you are not a long term forum member.

I like the simplicity, although few things I would change:

1. Too much space between lines.
2. It needs colours or at least shades of grey. Doesn't have to be extreme, but some faint cream or smth like that behind the text would be easier on the eye.
3. Use dark grey for the text to improve readability.
4. You need a logo

From functionality point of view, I would ad "Back to top" at the bottom of every article and "Go back to articles" at the top of every article. The latter should get you back to the place on the page where you were before entering the article - not the top of the page.

I like current simplicity so much that I'll share my disagreement:

1. OK for me
2. Please don't
3. Black on white is what I'm used to, and I would say this kind of a well tested configuration...
4. why?
5. "Back to top"? Seriously why people add these links on pages? I never ever click them.  There is this "home" button on your keyboard, and you can shift+click on the scrollbar also.

Reimplementing public APIs is permitted by law because APIs are statements of fact, not creative works.

However, copying things like header files or documentation is not allowed, as they are protected by copyright.

I used to work on the Wine emulator, so I am pretty sure it's safe Wink

Hah, nice. Great to have you around Smiley
166  Bitcoin / Project Development / Re: Project idea: clone Paypal API(s) on: March 30, 2011, 06:10:23 PM
Are you sure there cannot be some copyright issues? After all designing API takes some work, and I'm not sure if that design is free. With all these methods names and exact same error numbers it's hard to convince somebody that it was just coincidence.

I like it very much. Any chance for RSS/Atom ?
168  Economy / Marketplace / Re: bitcoin groupon on: March 30, 2011, 06:15:38 AM
My weekend got a bit longer, anyway, I'm glad there's some feedback Smiley

I've added link to the first post, may be helpful indeed, thanks. Also I introduced something like:

http://bitcoinity.org/soup

Because I like idea of reading all bitcoin news in one place. I'm putting the whole RSS's body there currently so I don't know if it won't turn out that somebody has problem with that (then maybe I'll just leave some links and little body with stripped html). You can add url manually, and I'm thinking about some voting (you know to have like news.ycombinator.com kind of news site for bitcoin), but I'm not sure if people want to visit site to view them (I like my rss reader personally), and because of this I'm not sure if there would be enough votes to make it usable.

Any kind of suggestions and ideas are actually worth more than my coding so very much welcome.

About open sourcing: I don't want to decide now something that I'll regret later, so I'm still wondering if that can really work out (but I guess it sounds good, but psst).

PS. http://bitcoinity.org/wanted?compact=1 XKCD leading so far Smiley
169  Bitcoin / Mining / Re: Nagios plugin for monitoring GPU temperature and fan speed? on: March 28, 2011, 02:03:49 PM
I prefer Munin as it works more out of the box, but I'll give it a try Cheesy

You would need to tune it for yourself but here's what I have for munin:


Code: (temperature)
#!/usr/bin/ruby

if ARGV.first == "config"
  puts "graph_title GPU temperatures"
  #puts "graph_args --base 1000 -r --lower-limit 0"
  puts "graph_category gpu"
  puts "graph_period second"
  puts "graph_vlabel temperature"
  puts "card0.label card0"
  puts "card1.label card1"
  puts "card2.label card2"
else
  out = `DISPLAY=":3" aticonfig --odgt --adapter=all`
  #puts out

  out.split("\n\n").each do |card|
    adapter = card.match(/Adapter ([0-9.]+)/i)[1]
    temp = card.match(/Temperature - ([0-9.]+) C/i)[1]
    puts "card#{adapter}.value #{temp}"
  end
end


Code: (fan speeds)
#!/usr/bin/ruby

if ARGV.first == "config"
  puts "graph_title GPU fan speeds"
  #puts "graph_args --base 1000 -r --lower-limit 0"
  puts "graph_category gpu"
  puts "graph_period second"
  puts "graph_vlabel speed"
  puts "fan0.label card0"
  puts "fan2.label card2"
else
  %w{0 2}.each do |id|
    out = ` DISPLAY=":3.#{id}" aticonfig --pplib-cmd 'get fanspeed 0'`
    speed = out.match(/Speed: (\d+)\%/)[1]
    puts "fan#{id}.value #{speed}"
  end
end

As you may have guessed this one is from machine that has 1x5970 and 1x5870. I was too lazy to do it using plugin configuration.

Very nice. Much better than I expected. I recommend either not rounding dollar amounts or rounding up. I pledged 8.99USD for a DVD, but the site says 8.00$. Also, use USD instead of a dollar sign. Perhaps you'll allow users to select different currencies?
  • Thanks a lot Smiley
  • quiclky changed from $ to USD before going out, seems better indeed
  • will fix that amount summing bug as soon as I get back
  • other currencies sound very reasonable especially for some more local online stores, but I guess some conversion will be needed for easier comparison
171  Economy / Marketplace / Re: bitcoin groupon on: March 26, 2011, 05:39:45 AM
Um... sorry dude, I won't tell my mother my password and I won't tell you either.

Maybe I'll create a dummy account and use that login to check it out.

Read carefully and tell me where I wrote something that may suggest such thing (so I can fix it). I do not need you forum password. Forum account confirmation is done with sending a prvate message on the forum to bitcoinity user.

I'm about to hit the road so I won't be responding fast. Form of data presentation will be improved for sure because now it's hard to read.
172  Economy / Marketplace / Re: bitcoin groupon on: March 26, 2011, 03:47:14 AM
I have some travelling on the weekend, but I wanted to show you something before going away so here it is:

http://bitcoinity.org

I've implemented I think the most important part that is confirmation of forum accounts, and this very bruteforce basic wanted sites list. If you like playing with software that may crash at any moment, feel free to check it out.

Little problem is, that once I started coding I couldn't stop myself and now I want to add 100 things there :/1

Usability will be improved, currently I just focused on collecting data properly. I'll be very happy to hear about issues and suggestions. As for these already stated:

  • I guess I can add entering amount in bitcoins if you really think there is need for it (then I would recalculate their value according to some exchange everyday so that we have up to date total amount in dollars)
  • About open source, yeah well I think why not (no guarantees), I'm doing this for fun non profit, however I would prefer to build solid skeleton on my own, if there are any requests currently I think in many cases I may code them faster than it would take to cooperate with somebody on this.

PS. Looks awful as promised.
PS2. Fixing my english welcome.
173  Economy / Marketplace / Re: bitcoin groupon on: March 26, 2011, 01:39:43 AM
OK I've prepared something. And before I share in public I would love some alpha testers, to make sure it works not only for me. If you have a few minutes, please PM me.

More info to come.
174  Bitcoin / Bitcoin Discussion / Re: Move Bitcoin.org to a Bitcoin Host on: March 25, 2011, 05:12:45 PM
But it's just a nice idea for the bitcoin project itself to pay for everything in bitcoin!

Just to be clear: I do agree that is a very nice idea. I just don't think it's rational in terms of bitcoin promotion.

Whois for bitcoin.org says it is currently hosted on rackspace. Great solution would be of course to make some well known provider like this to accept bitcoins. It could be great promotion for them as bitcoin is becoming popular. But I used to be running a hosting company, and as bad as it sounds on this forum - I would not accept bitcoins. The reason is: police have been contacting me a few times, and their most reliable link to know who's behind some site is a payment that he made for hosting. So I would be afraid about this - if you cannot tell who's account is it on your server, maybe it was you that done this bad thing. Of course you take personal information from person that is buying account, and if it turns out to be fake, it's somebody's else crime to give you fake data not yours to accept it, you could also ask for some document scan for registration or whatever, I'm just saying that I think it's harder for such service providers to accept bitcoins than it is for let's say online stores..
175  Bitcoin / Bitcoin Discussion / Re: Move Bitcoin.org to a Bitcoin Host on: March 25, 2011, 04:08:01 PM
My opinion is that none of visitors care. Just use the one that's most reliable. I guess so far uptime is good and I think that:

P1 < P2 * PF

P1 - number of people that will care&know about the hosting provider
P2 - number of people that will care&know about this site being down
PF - probability of site going down because of using some fresh and not necessary reliable hosting provider

176  Bitcoin / Pools / Re: Cooperative mining (150Ghash/s) on: March 23, 2011, 06:11:27 PM
It looks like when block is being processed, no getworks are sent. I understand that this is a feature, but could you let miners work even of the fake shares? It causes GPU to cool down for a moment, and as far as I know the worst part about high temperatures are temperature changes. If 90C stays on the card all the time is probably more healthy for it than when you have 80C and cooling every half an hour to 50C (Thermal expansion and stuff). Also for me it causes diablominer to freeze sometimes, but that's some software issue and maybe just my misconfiguration. If it is not possible to implement for you, maybe somebody have some suggestions on how can I keep them busy? I'm quite busy myself lately so something like writing software to switch to local mining or whatever for this time is too much for me.

177  Economy / Marketplace / Re: bitcoin groupon on: March 23, 2011, 07:22:10 AM
Youre missing something obvious here. Would a bitcoin  merchant want to be involved in a bitcoin groupon ? Then you can use bitcoins or at least a link to the product....
Its also good if a hundred bitcoiners get a discount at a USD store

Idea is obviously neat, but putting it in compressed version I think we are still far too small for this to work.

Its also good if a hundred bitcoiners get a discount at a USD store  Smiley
This gives me an idea. People want to buy stuff with coins, but the merchant doesn't take coins. Intermediary accumulates orders and bitcoin payments from consumers and negotiates a bulk deal with the merchant. Consumers get to use bitcoin. Intermediary pockets the difference. Merchants get extra sales and eventually take Bitcoin directly.

Easier said than done I'm sure.

I guess it's essentially a sales affiliate who handles currency conversion too.

Basically as above. I think we are too small yet. Intermediary would also need to take high risk currently because of bitcoin price changes while collecting bitcoins. And there are not that many of us, so discount rather wouldn't be high, so I would prefer to exchange my btc to dollars manually at desired rate, and then have pleasure of just clicking and having (without sharing with 3rd party what am I buying, and possibly also my address?)


But I'm just saying I don't think it would work yet. Whoever implements some idea first gets some advantage, so...these ideas are nice indeed.
178  Economy / Marketplace / Re: bitcoin groupon on: March 23, 2011, 01:12:01 AM
I'm really glad there is some interest. I was missing some project lately that I'm not doing for money Smiley I already started and I will let you know how it goes.

About discussion:
  • I think we should stick to dollar amounts - btc value still varies quite much and $ value is something that mechants understand
  • about escrow, I'm skeptical. ScriptGadget argument seems valid for me, and also I think our community is still small enough to trust these people with higher number of posts. From our side, I'd like it to be understood that if you declare yourself, you gonna buy it, but from the store owner side, it's rather obvious these are not 100% transactions, it rather only shows potential interest, so my vote would be rather against the jar, but I'm totally open for discussion
179  Economy / Marketplace / Re: bitcoin groupon on: March 22, 2011, 12:02:44 PM
OK, so I do agree forum is not the most efficient way for this, like for also so many other stuff that we are doing here.

I'm happy to put a site. Site will have a feature to confirm your forum account there (by sending private message to dedicated forum account), so while browsing it you still have some idea that these are not random people.

It will look awful, and it will work nice. But if I create such site (I need about 15h for this, I have a full time job so I'd need 3 days), are you willing to use it for such purpose? I do think it is more efficient, but I don't want to try to spread community outside forum. I'm happy to spend my time and create such thing if only there is some interest.
180  Bitcoin / Project Development / Re: Bitcoin.org Redesign (mockups inside) on: March 21, 2011, 10:56:49 PM
I don't want to hijack the design discussion...
... but I would like to open up discussion of content.  I'd like to see the bitcoin.org home page to be less about bitcoin-the-software and more about bitcoin-the-currency

+10

On wikipedia it's also confusing that this quick info box is containing information like: "Written in: C++", "Size 5.2 MB - 9.7 MB". It seems common to me that people think at the beginning it's all about this program and not protocol.

Also I like idea of having just a button for system detected from user-agent and just some extra link for showing others.
