trying to get a raspberry pi to read QR codes from a webcam.

im using zbar tools

sudo apt-get zbar-tools

zbarcam /dev/video0


This works just fine in ubuntu

but im getting errors on the rpi im running weezy

 ERROR: zbar processor in zbar_processor_init():
     unsupported request: no compatible image format



anyone work with the pi to do this before? surprised im not finding more tutorials going over this online.

what ive found
http://www.raspberrypi.org/phpBB3//viewtopic.php?f=41&t=16025

bitping posted the source code so I can run the server myself. (if i can ever get this thing going) looking for a gethub or something for bitcoin monitor and cant find it or anything else similar.

trying to get into experimenting with bitcoin web development.


When I edit the bitcoin.conf on my default install it was blank just with a password. Im trying to set it up so it can act as a server.


testnet=0
server=1
rpcuser=admin
rpcpassword=1234
rpcallowip=*


yet when I do this I get the error

(authorization failed) error: incorrect rpcuser or rpcpassword (authorization failed)

on the command bicoind getblockcount

I tried bitcoind getblockcount admin 1234



if anyone could link a good tutorial on this Id appreciate it.

https://en.bitcoin.it/wiki/API_reference_%28JSON-RPC%29

is just too vague

im trying to deploy bitping.net from the github


I got most of the way but im unable to get the full menu bar to propagate (just getting start)

and I had to comment out

//require("notifications.php");
//require("notification.php");

because I cant find either of those in the gethub?

I made an order and now im digging around for it.

If my VPS can handle it id be willing to host this.

what is the difference from a hard fork and a soft fork?

is what we are going though now .7 to .8 considered a soft?

If I wanted to set up a web-service that kept a live hotwallet with the ability to send bitcoin. How difficult would it be to set it up so that only stored address's (linked to a offline wallet) would be possible recipients?

It might sound like a weird request. but say I wanted to use bitcoin in a closed environment. (only between wallets I own) And thereby making it less likely to be compromised.

intruder would have have to first inject his own address then compromise the hot wallet system. I could easily have a secondary server that stores all the approved address's as a redundancy.

thoughts?

im wondering have you measured your bandwidth usage?

trying

i=1;for x in `cat add2.txt`; do qrencode -S -o $i $x; ((i++); done

is returning

bash: syntax error near unexpected token `done'





I need the files in order, because the order they are in the txt file is very different then "alphabetical" how it dumps out on my desktop

I tried moving my excel around and it counts differently.

the files are saving as the bitcoin address, and it acting weird with the order

1A...
1Z
11

vr

11
12..
1A


I tried sorting by "time" but that didnt work
 

so, ran into a bit of a snag


I need to number the files in the order they are processed.

-o FILENAME  write PNG image to FILENAME. If '-' is specified, the result
               will be output to standard output. If -S is given, structured
               symbols are written to FILENAME-01.png, FILENAME-02.png, ...;
               if specified, remove a trailing '.png' from FILENAME.



if I try

for x in `cat add2.txt`; do qrencode -o  -S $x.png $x; done

it does a single file named -S


ive tried

$-.png

$'-'.png

for x in `cat add2.txt`; do qrencode -o -S  $x.png $x; done

for x in `cat add2.txt`; do qrencode -S $x; done



I dont understand "If -S is given" trying to get the -01 -02 -03 ext

qrencode -o test.png add2.txt

returns a singular file png of "add2.txt"



qrencode -o test.png $add2.txt


returns a singular file png of "add2"




qrencode -o $test.png $add2.txt

does nothing


What am I missing?


my txt file looks like this

https://dl-web.dropbox.com/get/add2.txt?w=79ca2f0c

I have Ubuntu running on VMware.

can you show an example?

http://www.aurora3dsoftware.com/buy.html

is only 20$

still looking...

Think I found a script but im not sure how to use it.

https://dl-web.dropbox.com/get/generate.py?w=1d77d447

"The QR4 Desktop QR Code Software package for office use costs 1489 €"

really? some one actually paid them that?

I've used the Google QR code generator before.

But I want to run a script that takes a list of address's (excel or csv) and turns them into hundreds of individual .jpg files.

ware do I start?
