161  Bitcoin / Mining support / Bitparking says 0mh/s on: August 04, 2013, 04:03:20 PM
The hashrate reported at bitparking.com/(user) is saying zero.

I only have a single USB eruptor. It's saying:

162  Bitcoin / Development & Technical Discussion / Bash script to sound when coins received - need debug on: August 01, 2013, 09:28:23 PM
Goal: Make a sound when balance at an address reaches a set number of confirmations

So far:

Code:
#needs:
# - pulseaudio - for paplay
# - curl
# - blockexplorer not 404

address=$1
confirmations="6"
balance=$(curl --fail "http://blockexplorer.com/q/getreceivedbyaddress/$address/$confirmations") || { echo "Unable to retrieve balance" >&2; exit 1; }



while $BALANCE=0
do
 sleep 1s
 echo $BALANCE
done


echo $BALANCE at $ADDRESS received with $CONFIRMATIONS confirmations.
paplay /usr/share/sounds/startup3.wav

Needs a bit of tweaking.

I did a search and found bash scripts in this dev section so I'm posting here... but it doesn't seem the best section to post in, sorry if it's wrong
163  Bitcoin / Bitcoin Discussion / Re: idea: QRcard - fully offline hardware wallet on: August 01, 2013, 05:48:15 PM
All we need to have something workable ASAP is an android device with a camera and eink... but I don't think one exists (other than a Nook with USB camera clumsily hanging out)

Other than this I suppose there are android phones and cheap chinese tablets that you could solder over the wifi or try to put a switch on the antenna but they're not that small.
164  Bitcoin / Bitcoin Discussion / idea: QRcard - fully offline hardware wallet on: August 01, 2013, 11:40:53 AM
 2 items required:

- eink display
^ display good enough to show QRcodes, eink seems most appropriate
- camera
^ this can be cheap and low quality.

The devices generates addresses and transactions, that's all. Interaction is done via the screen and camera, nothing else.

While I think the various hardware devices are great this is a lot simpler to communicate to people than USB sticks.

It would be simplest to use Android, or something that can run python and use a client that already exists.

I'd like to make such a device but it's beyond me.
165  Bitcoin / Electrum / Re: Online label syncing plugin in Electrum 1.7 on: August 01, 2013, 10:01:41 AM
I just want to be 110% sure about this - we're just syncing labels which can be used to make a record of what each transaction was and is for, for easier accounting.
Transactions are noted but these can't be abused in any way and private keys aren't transmitted.

Thus, the encryption is there for financial privacy.

Just want to be totally sure that this is what it is?
166  Bitcoin / Electrum / labelectrum - labels only? on: July 31, 2013, 06:51:13 PM
I'm thinking of using https://labelectrum.herokuapp.com/ to syncronise my labels.

But I don't want to synchronise wallets because I see that as a risk even if its ssyncronisetore encrypted. Are the private keys transmitted or just the labels / history?

p.s. it would be nice to be able to freeze multiple receive addresses in one go by holding the shift and ctrl keys

168  Other / Beginners & Help / Re: Is the Bitcoin ecosystem sane? on: July 30, 2013, 11:47:02 AM
Acceptance is a very important indicator of how well Bitcoin is doing.

However, look at gold. I've tried a few times to see if a shop will accept a gold coin and they never do, or if they do they like to make a fat profit from it. Yet gold is still seen as a currency and countries in particular use it for payments.

The question then becomes,
how much is speculation and how much is real value? That's the hard one to answer. In particular it's difficult to unpick people who have a small store of emergency funds as BTC because it's harder to confiscate than gold for example.

171  Alternate cryptocurrencies / Altcoin Discussion / Re: Bitcoin bridge - Ripple on: July 23, 2013, 07:48:31 PM
The point I'm trying to make is that debt has been ill advised for a very long time.

 Yes, it has the advantage of making new connections in the financial system but it also allows for ebbs and flows and massive crashes due to the extra linking. Movements like this are natural for any network. When you take out a loan you allow the lender more than interest - but also an extra facet of control that is not at all obvious.

 Unlike Bitcoin, Ripple is based on this same broken system.

 I don't write off advise from a source because that source is unfashionable. All the major religions have something to say about debt. If you want to write off religion as a source for what people thought in the past then there isn't much left in history.

 Science is like a disrespectful brat right now to it's parents which are religion and philosophy. The attitude is slowly maturing.


In reading this thread we've seen a few people who don't know what Ripple is, nor how it is different.

With Ripple you are trusting other people to pay you back. That is "Promise to pay the bearer" as printed on GBP notes and specifically advised against as a bad idea in the bible. It's an IOU but unlike a Hawala notebook it's digital. Howeverm here's the interesting bit: you can infer trust to someone you don't know via someone else. Thus, if there's someone on the forum yoiu don't know you might be able to get trust via that someone else.

This is good when people are paying their debts but if it goes wrong the debt default Ripple goes through the entire system.

The other good thing is that Ripple facilitates setting up an exchange through the gateways. However, it's not as easy for the average user IMHO.

Finally, the whole thing is glued together with XRP and that is dodgy.

Scam or not, you must at least be aware of all this stuff!

wait you are referencing a book written a few thousand years before modern financial systems were developed for giving financial advice?

come on....

What I mean is that at a setting of 0.80/-0.80 I find that it tends to get to miss the very small timescale(daily), get it wrong on the short timescale(weekly) but get it right on the medium (monthly) scale.

This is of course very general and it hasn't been tested enough. The short weekly timescale is a shame. For example in the log here I have:

Which of course is the very opposite of what you want right!

Now, come to think of it, I remember why it caught the 70 dip - it was because I manually intervened and then used the bot to buy if anything changes.

I was hoping that I could use the EMA to catch those very large changes and basically create a less speculative more stable level but it doesn't seem to do that and just holding USD would be better at that.

Anyone had any wins with EMA?
Even though it's made losses I somehow how feel safer thinking that something less human is watching some coins for me. I'm not sure if it's too early to say experiment failed.


What values do you run it at?
Always seems to buy low and sell high for me... but it did catch the more major dips so far which is handy

Been running it for a few days, tweaking it ever so slightly and watching the results.

One thing I've noticed is a profit calculation hasn't been shown afaik for me in the time I've been running the bot in simulation mode.

Any known reason for this I've missed.

That is what it suppose to do. It follows the flow of the market so if the 'flow' changes a lot in a short time you will lose some money.
But once the market moves big in a certain way for a longer time period you will be on the right side.
173  Other / Beginners & Help / Re: Newbie Introduction/ASICMiner Erupter USB Question on: July 20, 2013, 11:22:48 AM
I did a group buy. I trusted because there was use of PGP and so forth signing who gets what etc.

I did only buy 1 though.

What I don't understand is why people get them. They're about $90 for one and I make about $0.03 cents merged mining off of mine which I expect probably doesn't cover the cost of electric running off a Raspberry Pi so there's need to have use of whatever system it's plugged into or buy more of them.

Surely all these people buying so many of them are making a loss.

It's a funny thing how the mining has changed. We started off in a decentralised manner with everybody able to mine and now it's more a case of - can you find the ASIC cheaper and before everybody else does (BFL probably the winner here).

Anyone with a Erupter seems to me to be supporting the decentralisaton but its at a cost to them. hmm... this is weakening BTC don't we think?

178  Other / Meta / Re: Purposely offering your own goods in someone elses thread... on: July 18, 2013, 11:59:47 AM
I think it is important to allow people to post competition in other people's threads.
Such free speech and free competition is exactly the sort if thing that enourages the market to be efficient.

It's a brilliant micro case study as to why people should be allowed to do things that are considered rude.
Another example would be standing outside a shop and poaching customers. It appears unfair but actually it is fair if the shop is free to do the same thing back to the poachers.

Being liberal on this is more efficient as it requires no action.
Being liberal also encourages the price to come down, better for consumers. And finally, it's a more efficient market.

In my culture I think it's rude but anglophone countries are particularly territorial and the UK is particularly territorial too. You wouldn't get the same opinion in Romania and probably many other countries (China) so you have to bear that in mind. They would say it's fair game.... no wonder those countries are on the way up.

edit: of course the disadvantage of a separate thread is that people are less likely to find that separate thread so it's worse for the consumer to have that and better to have a free-for-all.
Speak to a shop owner and he might say he's in favor of liberal business... but start poaching customers and all of a sudden capitalism seems to be a bad thing. That's the problem with people, it's all good when it's going there way but then when someone else starts doing the same they want special dispensations.

There's also these:

http://www.cxss.org.uk/drupal51/node/18

of which the easiest solution with support (in particular for arranging people, rather than just the tech) is:

http://www.cxss.org.uk/drupal51/?q=node/10
and fees to help with that: http://www.letslinkuk.net/practice/online.htm

or self hosting that to save some cash. The advantage of that system is that there's someone there to help set it up, host it (if need be) and be there to help if it's needed.
The disadvantage is that unlike Cyclos it's extremely basic. I'm assured that records can be exported from that system at at later date if needed.
180  Other / Off-topic / Local currencies accounting system 2013? (OpenTransactions ready for use?) on: July 18, 2013, 09:04:30 AM
 Last time I looked at LETs accounting systems was a couple of years ago now. What's changed since?

 Ideally we're looking for a way for members to go online, check their balance and pay and be paid easily. I shouldn't need to go into too much detail as to why the idea is to use this rather than Bitcoin or cash other than to say that there is some firewalling to the market this way.

 Last I looked we were going to use Ripple but it was very different back then and I don't want that much ease of connectivity to other markets.

 So what I'm looking for is decentralised accounting.

 Would this be OpenTransactions? Is it stable yet? (edit, update: No, not ready according to the git site) Is it (very) easy to use for old people? How would we handle people who don't really use computers? If so, where would be best to host it? I could pay for a low end server and do it but I'd rather use someone else if possible.

As an alternative, in a simple way Ripple could be used for this couldn't it? Let's say I was treasurer, then everyone would have to trust me with their currency. The next problem would be that I can't change my password and I can't share the job. So I think Ripple is no good (yet?).

 Any solution has to be totally ready as an alternative, in a simple way Ripple could be used for this couldn't it? Let's say I was treasurer, then everyone would have to trust me with their currency. The next problem would be that I can't change my password and I can't share the job. So I think Ripple is no good (yet?). And with a slick interface. There can't be any java interface shernanagans for the users.  

 What about more established online accounting systems? The most important thing is that any data can be exported and migrated to any new system that comes out down the line. Could a group edited Google spreadsheet actually do this since we have such a simple system?

 At the moment they're using one guy who makes a note of everything manually on the phone.

edit:

Just found Cyclos... seems like the best yet?
There's also https://www.community-exchange.org/ but it looks centralised and not making use of cryptography as much as Cyclos.
