Ah, righto. They are minuscule amounts apart from XPM which is a few dollars. I had to trade the XPM into the other things and back again :p Probably lost it all in the spread, who knows



I can't click the buy or sell buttons anymore. This is the same with Opera, Firefox, Chrome & Midori on linux.
Could be something to do with the javascript auto copy/paste ?

sorry to quote bump myself but can anyone comment?

Jago25_98, it's been a long time since I've bought and sold on Vircurex but I think I recall this bug.  How much are you trying to buy or sell?  I seem to remember that the buttons wouldn't work when I attempted to enter really small values.  I think vircurex has certain amount thresholds and it was quite annoying because the site wouldn't warn you that your values were to small.

In my case, this would especially happen when I would try to get rid of fractional, USD/EUR values.  I think you can only use fiat to by any coin if you have more than .01 of that fiat currency to spend.

In fact, if I logged into Vircurex right now, I bet I have something like .0005 USD and .00001 EUR.  It annoyed me because I wanted to clear my balances but I was never able too.

Note: It's also worth noting that all other exchanges behave this way, however, the others that I have used have always warned me about my errant values.  Those exchanges are MCXnow, BTC-e and Cryptsy.

I think encryption of messages sounds great but not too many people know about it or how to use it and TBH I think encryption is a little difficult to understand. I mean, even Nimda was offering lessons on PGP/GPG encryption here on the Bitcoin forum where you would expect most members to be pretty tech savvy.

Very much agreed. It should be simpler.
I think the key to things like Blackberry Messenger that have become more widely used is that the keys are already generated. I know this is not as good as making sure you generate your own but it means it's alot more likely to be used. The insecurity this brings up only opens up a crack for feds and above to get in and most people only need a little bit more security than they currenctly have.

Thus an example,

 k9mail (or a new app) should automatically generate gpg keys and pair this to your email on install, unless otherwise instructed. The pubkey is attached automatically and al messages signed by default.

BitMessage is a decentralized, encrypted and peer-to-peer messenger. This program has seen a surge in popularity since the Snowden leaks.
TorChat is an easy-to-use anonymous messenger designed to fit nicely into the Tor environment. It has been widely used across the Dark Net spectrum since before Tor Mail’s fall.
PrivNote is a Clear Net messenger service that deletes notes once they’re read. Silk Road vendor RxKing prefers this service, but others refuse to use it, citing multiple security concerns.
SMS4TOR is a Tor-friendly version of PrivNote that has gained considerable traction thanks to its base a Tor hidden service.
I2P-Bote uses the I2P anonymizing software to provide a decentralized, encrypted, verified email service. The service is only in alpha and, due to its reliance on I2P, will probably not be widely adopted.
Privatdemail is an email service with a focus on privacy (as opposed to anonymity). Here’s a fun fact: You apparently can’t email Israel because the servers are located in an Arab country that forbids it. That policy will not inspire confidence, but even so, Privatdemail is already in use.
RiseUp is an email service built for “liberatory social change.” Users must apply and be approved for accounts, proving that they are activists fighting for positive change, which is whatever RiseUp’s founders deem it to be. In exchange, RiseUp keeps minimal logs, encrypts your data and defends your communications unlike many corporate email services.
Nym is a remailer that allows you to send encrypted emails without them being traced back to you, the sender.
Mixmail is a remailer similar to Nym but is much easier to use. It strips out identifying factors like an IP address, making a quick, anonymous email an easy proposition.
Jabber is a popular open-source, decentralized messaging system. It’s widely used by journalists already, particularly in the Middle East.
Tox.im is a currently-in-development tool that promises to allow encrypted and decentralized video and text chat reminiscent of Skype—only without Microsoft allowing the American government to listen in as they do.

I think an important test of Bitcoin is will people outside the USA buy Bitcoin to give a support level if the USA was to drop massively thus leading desperate people to cash in their BTC savings? - how to analyse that other than simply looking at country distribution?

If we look at:
https://en.bitcoin.it/wiki/Bitcoin_Ladder#Top_countries

we see a few BRIC countries...
 key ones for me are Poland & Russia. Brazil seems a bit reliant on USA trade? - as do the other big ones?

 So it's difficult to say what if would take for BTC to decouple to the dollar. One thing's for sure - we need to get Bitcoin spread more multilaterally & economically in order to further secure it. Growing use in USA antagonistic countries such as Venezuela & Russia is bullish. states.


edit: This presupposes a drop in the USA dollar and stocks. While many have been going on that the USA is about to fall for ages you have to remember that it is the global ruler and if times get tough cash tends to flow to the core, hence the USD bull run.
171  Bitcoin / Hardware / Measuring USB device power consumption with a Raspberry Pi (i.e. Block Eruptor) on: August 06, 2013, 12:58:22 PM
From:
http://elinux.org/R-Pi_Troubleshooting#Troubleshooting_power_problems

You can use a multimeter to compare power usage before and after you plug in your USB miner:



Code:
Results of tests:

Before tests: 4.90v available, 4.91v before polyfuse, 4.69v after polyfuse
With Eruptor: 4.54v avail, 4.91v before PF, 4.58v after
With no external power HDD: 4.90v before polyfuse, 4.46v after
Immediately after tests: 4.71v avail, 4.92v before fuse, 4.72v after and noted increased after 1min to 4.74v but after 5mins did not recover further; did not test for longer.

The HDD was noted as not fully spinning up.

Conclusions:

- a HDD needs external power no matter what. I expect if I was to test a flash drive power use is lower
- a Block Eruptor is right on the limit of what my Pi can supply. What probably happened was that it worked at first but then an increase in CPU load pushed the Polyfuse into action. This was then increased by the HDD when I tried that to test it. Now the PolyFuse has a lower limit so neither will work - I have to wait for the USB PSU to arrive before I can the Eruptor back in like I did before
- the PSU isn't supplying 5v, probably due to poor cabling
- the PolyFuse doesn't recover fully when stressed but this is no big deal

Thanks folks and in particular jbeale :-)
This has also been very useful in giving a way to measure what voltages USB devices consume.

Is there somewhere with more info on these sticks just as how to assess if they are heat damaged

+1

I would imagine heat damage will cause one of 2 things:

1) reduced hash rate. These run very precisely (ive got 335 Mhash and 334.9 Mhash respectively), and heat damage to the asic chip would result in fewer (if any) hashes.
2) increased error rate: much more rejected shares or hardware errors.

I find with a small heatsink to add slight cooling bonus, my HW errors sits around 1.3%. Without any cooling, and the 2 devices horizontal above eachother and creep up to 1.5-2.3% error rate. this alone makes a little bit of forced cooling a bonus for hardware lifespan and ROI

Thanks for sharing the experience of this.
Who designed the Eruptor? Don't they have some kind of page or tool for querying the device?

AFAIK the USB Eruptor is very basic - USB-Serial interface -> ASIC. No diagnostic output, no temp sensor, no firmware. I can see header pins on the board though

WL-500g Deluxe (WL-500gx)   BCM5365P/BCM5364P 200MHz   SoC   802.11g (BCM4306 + BCM2050)   32MB SDR 32bit   4MB   2 x 2.0 (VT6212L)

I'm not sure that'll have the resources to run cgminer :/
But It should at least start. The compiler optimization maybe set for later processors.

Yeah that's probably it... though I would have expected something more verbose to help me figure that out. I guess if so I'd have to figure out how to cross compile... easier to change to openwrt and use the supplied distro copy.

Meanwhile, the beaglebone (angstrom) doesn't recognise the Eruptor with lsusb.. perhaps not enough power even though the Eruptor lights up and all looks ok...

...and USB ports on the Raspberry Pi are producing errors now. So all 3 platforms each have their own problems...

175  Bitcoin / Mining software (miners) / Re: CGminer v3.3.1 on Broadcom based DD-WRT / OpenWRT on: August 05, 2013, 04:20:32 PM
its integrated as a service

so you start it like this sudo service cgminer start/stop

I see what you're saying but I wanted to check the binary does actually run before installing as a service... it should run. I would expect if I installed the whole thing it would still fail

What's the router?

WL500G-Deluxe so that's a BCM4702/4710. One has a very old Oleg firmware, the other has what appears to be the latest DD-WRT from 2010. I've only tried the DD-WRT one andthat's the one that gave illegal instruction
177  Bitcoin / Mining software (miners) / Re: CGminer v3.3.1 on Broadcom based DD-WRT / OpenWRT on: August 05, 2013, 01:18:25 PM
a NFS share on start-up could well work. I think you could do that with a start-up script in the admin panel. Mount it top /opt and you should be golden

Though that does mean you'll need another computer on all the time... so why not hook the miner up to that???

because then I'd need a USB hub and mine's taking ages to arrive from china.

Just tried running cgminer-3.3.1-mipsel on dd-wrt v24-sp2 (build 14929) ((old - will try upgrading...):
Code:
root@router:~# ./cgminer -n
Illegal instruction

Seems I'm just talking to myself here using this thread like a diary. I was hoping someone might chime in and tell me a way to monitor the temp on the USB Eruptor.

Tried a USB flash drive in the Pi and it works... and the Eruptor works on the laptop (I've no USB powered hub yet to help with testing) which all points to the mips compiled cgminer... but different versions and I still get 4bytes etc and so forth.

I still think I've overstressed the Pi USB ports somehow. It would be good to be able to know that the ports are ok for sure.

update:
Now running on a BeagleBone but need to create the /dev/ entries for /dev/ttyUSB0 or AMU0...
179  Bitcoin / Mining software (miners) / Re: CGminer v3.3.1 on Broadcom based DD-WRT / OpenWRT on: August 05, 2013, 11:51:14 AM
 I don't want to use a powered USB hub if possible since I only have one miner. However, I think the problem is that I need to put the cgminer executable somewhere and that therefore needs extra USB storage right - and therefore a USB hub.

Unless I mount a network share...?

An alternative in NZ would be good. The guy running BitNZ... I think sounds like a busy guy and doesn't need the income so much. I think it's run, certainly at the start as a charitable thing for Bitcoin point of view.

As such, I hate to say it since it's a profit making thing but... don't moan too hard as we need the site up and running.

Hopefully an alternative in NZ will turn up at some point as a backup.

I'd also like to see a market order option to help newbies. That change didn't happen either which makes me think it's always going to be a bit neglected.
