i have a forum running the same software and only the admin can delete accounts try messaging theymos >https://bitcointalk.org/index.php?action=profile;u=35

EDIT you posted while i was still typing
The docs suggest otherwise, so the admins have probably disabled account deletion:

Interesting, definitely some classes in there that can save me some time and trouble. license ?

dunno, lets say gpl for now

If you want people to actually be able to use it you'll need to put the license on Github, e.g. with GPL you need to supply a copy of the gpl, and should add headers to the file just to make things clear (See https://www.gnu.org/licenses/gpl-3.0.html ). Without clear licensing no responsible developer will touch the code with a bargepole. (GPL is a fairly safe first choice -- all improvements have to be rereleased as source code, and you can always switch to more permissive licences later should you wish.)

Add more swap, run bitcoind from git.


Doesen't swap wear the SD card?

(snip)
If you are concerned about swap wearing the SD card, just use a USB thumb drive or something to hold a swapfile instead.
I've worn out a few thumb-drives doing that back in the days when I used Knoppix (but those were fairly cheap thumb drives), better bet is a hard drive or ssd (not sure how good an idea the latter is) -- not as fast, but the RPi isn't that fast either.

Re: [REQUEST] Developing Bootable Bitcoin-QT

Probably best to start with Damn Small Linux, and customise things as needed from there -- I'm assuming you'd want to update the whole CD every time you have a new Bitcoin-Qt version, otherwise you'd have to store it on the USB drive -- but ideally you would set the system up to not run any executables from anywhere except the cd. (Using LUKS with usb drives works well, so no issues with encrypting things there.) It's probably also worth having a wrapper program which can launch Bitcoin-Qt (or Armory, which I'd include if I was doing this myself, at least once the stability issues are solved) and deal with the mounting/unmounting of the external drive.

I like to run Bitcoin-QT through Tor. But I can't operate Armory when QT has Tor running. So, I have to open QT, disable Tor proxy, restart it, then I can use Armory. Is there a better way to do this?
You'll need to play around with the configurations a bit for everything to work with proxies: I think I had to add "listen=1" to my bitcoin.conf for armory to be able to connect to it again.

Any numbers on how many people are using the BTC option so far? Would be quite interesting to have that, and average BTC payment (probably in dollar terms) would also be quite interesting.

It still relies on coinbase spotting the transaction and sometimes that's been slow.
I think that's probably the problem I had -- But anyway, just noticed there's both the bundle and also Alan Wake on sale, so just snapped that up too! This time I waited for 1 confirmation to see what happened, and that worked fine -- but I still think it really should be made a bit more obvious somewhere as to how long it could take, since people less experienced with Bitcoin etc. might get worried. Anyways, it's pretty cool that I can get stuff with my BTC, and I'm sure things will be improved with time!  Smiley

The coinbase pages seem a bit clunky -- especially not telling you about how many confirmations are needed (apparently 5) -- and showing that 0BTC are present up until that point meaning you have no way of knowing what's happening. Also annoying that the BTC price changed every time I pressed confirm payment again (how am I supposed to know that they payment will fail until it's 5 confirmations?) -- luckily the BTC amount decreased as time went on i.e. what I transferred was enough and that didn't cause any extra failures, but still not too user friendly.

Hi, thanks for your reply.

I ordered one a few days ago, i could cancel the deal and get a raspberry PI. But i wouldn´t use HDMI too and maybe go for lan and buy a usb to lan device.

I dont have much experience in usb to lan, do you think this works well with Linux ?

Would you recommend canceling the deal and get a PI instead ? So if it got heat issues, why dont remove the whole case and just apply a big heatsink ?

Thank you  Smiley
Yes, USB Ethernet adaptors are well supported under linux -- there isn't great variety in the chips that are used in these. In my case I got the cheapest one from Amazon, which was in fact a "Wii Lan Adaptor" -- note that they won't necessarily advertise Linux compatibility. USB Wifi adaptors are a bit more tricky, but if you do the research you can find a Linux compatible Wifi adaptor cheaply, e.g. I use a TP-Link TL-WN722N / TL-WN722NC which has a proper antenna + long cable (this one was considerably stronger than a simple usb-dongle without external antenna which I also had, i.e. let me reliably connect to a network which my phone and laptop couldn't connect to).

Yeah, but you can't run anything professional with a bitcoind that is restarted every hour.

I think the bitcoin community really needs to move out of the garage; if we're ever going to get this thing going.
You can't go professional running anything on a Raspberry Pi. It's not designed as a professional piece of equipment. Especially something as memory/storage intensive as bitcoin.

Ps. you should probably look at http://binerry.de/post/28263824530/raspberry-pi-watchdog-timer for making sure you can deal with your Pi locking up (never happened to me, but I don't push mine very hard) if you are using it for something important.

Hm, interesting! I just feel a bit uneasy about feeding the routers "own" power back into it.

Feels like it might work fine until there is a spike in the grid and then: poof your hub is toast, and if you're unlucky your house burns down with it...

Do you know what the USB spec. says about this?

Edit: Please see this quote from a user on the raspberry forum:

Quote
If you leave the red wire intact, (and are thus "back-feeding" the PI, as its commonly called) you are in fact bypassing the PI's F3 polyfuse.

There is one single case I am aware of where this caused trouble when that user also used a badly designed power supply to feed the hub. The power supply wasn't properly regulated, and unloaded it outputted more than six volt! When he plugged it in it triggered the over-voltage protection diode of the PI (which triggers at about six volt) the resulting short circuit current though the diode, unimpeded by any fuse, overheated the diode so much that it melted a hole in the enclosure of his PI!

Its thus much better to "cut the red wire", and not to back-feed the PI!
http://raspberrypi.stackexchange.com/questions/4880/powered-hubs-backfeeding-and-safety has some more useful info. But basically unless you've cheaped out on an unregulated USB hub you won't cause damage, and in most cases things will just work without problems. Neither of my PIs has failed yet, the one which I have always-on hasn't crashed once. (48 days uptime ATM, i.e. since the last time I was rearranging cabling and had to unplug it.) If you're really interested I reccomend looking at some USB hub circuits online...

FYI: If you wan't to recursively both power the RPi with the hub and control the hub with your RPi at the same time just cut the red wire in the uplink cable.

Code:
-P +-------+
 | |       |
 | c       |
 | |       |
+-------+  |
|  hub  |  | < SOLUTION: Cut the red wire here!
+-------+  |
 | | | |   |
 p o o o   |
 |         |
 | +-----+ |
 +-| RPi |-+
   +-----+

o = other "power hungry" devices
P = PSU power
p = USB power
c = hub controller

For my part o = 1xBE USB and 2x50GH BFL, I hope the RPi will be able to run them!
That shouldn't be necessary -- both my RPIs are powered from the hub they control without any issues so far. (Although that might depend on the hub...) I've never heard of anyone having to cut wires for this sort of thing to work.

Re: Making 0-conf TXs relatively safe "again"
by
qualalol
on 18/05/2013, 09:55:50 UTC
The whole reason the block chain exists is to prevent double spends.
If anyone finds  a "safe" way to accept 0-conf transactions, without sacrificing any other major features of bitcoin (pseudonimity, decentralisation), this would render bitcoin obsolete - just through away all the blocks in favour of one big pool of unconfirmed transactions.

I don't see how why my proposed solution above doesn't work, and also why it should render the blockchain obsolete.

Maybe I wasn't clear enough; let me try again.

Say I am a customer, and want to buy a product from V for 0.1 BTC, double spend safe. I need to have *two* confirmed transaction for this purpose. Say I know the private keys for TX0out, which has 1 BTC, and for TX1out which has 3 BTC out. Both are deep in the block chain.

I will give a usual transaction to V which pays him 0.1 BTC, giving me 0.9 BTC change. But additionally I give him a transaction which says: "If you find two valid signatures for TX0out, this transaction gives the miner 2 BTC from TX1out, and 0.1 BTC to V".

Anyone care to explain to me why this would not work?
Because after you give the transactions to V you publish further transactions transferring all coins from TX0out and TX1out to another address you own... ?

BRING ON THE FORKS!

ITS PAST DUE WE FIX BITCOIN!

E-Mail BitHits.info@gmail.com if you are interested in doing this.

I'll be starting a website in the near future dedicated to fixing BitCoin before self-righteous fucks destroy it with what 'they think' is best for BitCoin.

Why do you hate freedom?

Miners now (post 0.8.2) will have the CHOICE (but not requirement) to restrict uneconomical transactions to improve the efficiency of the network.

What about choice do you find so scary?

The default option is scary, it should be set to 1 satoshi by default if anything.
No it shouldn't. The end-user should read the release-notes, make a decision on what they want, and change the default if they feel the need to change it. If they don't bother with that they are essentially saying "we agree with whatever the publisher thinks", and the publisher of the most commonly used branch believes 5430 is the best default. If you are downloading new software but too lazy to look at what it does then you have no right complain about it.

Re: WARNING! Bitcoin will soon block small transaction outputs
by

on 14/05/2013, 15:36:12 UTC
Gavin Andresen has changed the Bitcoin code to block any output with a value of less than 54uBTC:

https://github.com/bitcoin/bitcoin/pull/2577

Many Bitcoin users are going to be affected and see their funds blocked. For instance ASICMiner share payments, BitHits faucet payments, anyone depending on microtransactions. If you depend on small payments you need to change your business model now or find yourself shutdown overnight.

Gavin: It's sad that you aren't willing to speak about this publicly on the forums, rather than hiding away all the debate on GitHub away from the general public.

edit: To be clear, I like the patch: https://github.com/bitcoin/bitcoin/pull/2577#issuecomment-17138223

What I don't like is when I realized not once had Gavin or anyone else in the development team made a public statement that this change was coming down the line. If I hadn't made this post, for all I know it would have been hidden away in the next Bitcoin-QT with no warning at all, right when we all have to upgrade before May 15th.

Why isn't think on your blog or someone else so people have time to change the way their businesses operate? Why the secrecy?

For the record, the forums no longer count as "public" as in "well informed public" but "public" as in "mob". I can understand why this wouldn't have been done on the forum. No offense, but you're a user with 28 Posts and you're essentially accusing one of the most important guys in bitcoin of some sort of underhanded secrecy. That doesn't mean that you can't be right, but still, it's a mob mentality down here, and there are thousands of us down here ready to tear anything apart.


Well if walks and sounds like a duck, it is.  What makes this Gavin person any more important the anyone else?  I am willing to bet he profits from this somehow. Maybe all us unwashed masses should revolt. Down with the king
What makes Gavin important is that he maintains a bitcoin client, and a whole bunch of people decide to use his bitcoin client. They could instead very easily decide to have their bitcoin client supplied by any other random person that decides to maintain their own client. If everyone started obtaining their bitcoin client from someone else then Gavin would no longer be important. Everyone is free to choose who they obtain their bitcoin client from. They can even start maintaining their own bitcoin client. You can find the sources here, no one is stopping you from having your own client. Good luck in convincing others to use your client!

Re: The Switzerland of Bitcoin
by

on 02/05/2013, 16:48:59 UTC
We have to look past the fact how the OLD currency system used to work. Everyone knows that paper money is not made for online transactions. So for a country to become the 'switzerland' of bitcoin does not necessarily have to depend it's ENTIRE economy on bitcoin, it can simply adopt it's traditional currency for day to day & physical use  while adopting Bitcoins as the officially recognized currency for online transactions.
I see. So, Why isn't "The Internet" on the list?

Switzerland's economy is largely banking and finance-based. In order for something to become the "Switzerland of Bitcoin" it would need to base a large portion of it's economy on bitcoin services. If you mean by that, only online services, then why must there be a physical location at all?
False: The financial sector is only about 12% of GDP.

Switzerland looks as good for BTC as it does for Fiat precisely for exactly the same reasons: neutrality, stability, independence. Laws aren't set on the whims of those in Government or their sponsors (mainly since the people have full control over the laws, partly since you don't have one overall leader and/or leading political party), and due process is more or less guaranteed.

Updated again:
- Settings now stored -- the exchange and your update frequency/percentage are now remembered.
- BTC-E supported (SSL certificate problem found -- need to check exactly why this was happening but currently I'm not bothering with checking certificates as security isn't really an issue when checking the exchange rate).

I'm working on:
- Wallet notifier: using blockexplorer to check address balances.
- Maybe more exchanges. Definitely looking at including the http://www.ounce.me/ average, and other data from there.

Updated version is up, which should now work properly. Also offers checking of Bitstamp. (I'm having some issues with BTC-E at the moment, so that's disabled.)

The new version uses a php proxy/cache: this is to avoid the browser caching the json from the Exchange (by setting no-cache headers), and also to allow access to APIs that are only accessible via SSL (i.e. every exchange apart from Mt. Gox only lets you access the API via SSL -- the browser won't let js on a non-SSL site to access SSL sites and vice versa). Note that this new cache only updates externally at most once a minute, so setting your update time to less than 1 minute only means that your browser will contact my server more often, but my server still only contacts the exchanges at most once per minute.

Interesting colour scheme you used there lol.
I'm just living up to the stereotype that people who can code can't design UIs...  Wink
