Bitcoin exchange rate plasmoid for KDE

[stakhanov]

I made a simple plasmoid to display the current exchange rate at Mt. Gox on KDE (a desktop environment for linux). You can download it from KDE look: http://kde-look.org/content/show.php?content=138572

Enjoy!

Sounds great

But.. is it just me, or is the ZIP file empty?   

[stakhanov]

It's not just you... Bummer!

Thanks for reporting, I'll look into it.

[stakhanov]

OK, it should be fixed now.

[Cryptoman]

How does one install it?

How does one install it?

Download the zip file, unzip it, and type:

Code:

plasmapkg -u btcRate

Then the plasmoid should be available when you select "Add new widgets" from the desktop or the panel. Let me know if it works!

[Cryptoman]

It installed fine, but when I went to add it to the desktop I got the following message:

This object could not be created for the following reason: Script initialization failed

I'm running OpenSUSE 11.3, KDE 4.4.4.

[stakhanov]

Could you run it with the following command, and paste me any error mesages? Thanks for testing, by the way!

Code:

plasmoidviewer btcRate

[Cryptoman]

Code:

> plasmoidviewer btcRate
QFont::setPointSize: Point size <= 0 (0), must be greater than 0

I think the problem is that you have python 2.6. I have uploaded a new version that should work better.

[Cryptoman]

Indeed, I have 2.6.5.  It works great now!  I sent you a donation.

[stakhanov]

Thanks!! I'm glad it finally worked out. Getting even a simple piece of software to work on other people's computers is hard!

[stakhanov]

Thanks to the generous anonymous donor who sent me 1.26BTC!

Hello and thanks for the plamsoid.


I wonder, why does your script call for gettrades.php and not tickers.php? Wouldn't the last one be easier to read?

Also, could you add the volume to the plasmoid, so we can juge the liquidity of the market too?

Thank you very much

[stakhanov]

Thanks for taking a look!

Could you give the full URL for tickers.php? I haven't been able to find that page.

I think I could add the volume info as a mousover popup. I'd also like to add a trend with rate of change, but I haven't figured out yet how to estimate these robustly.

Here's the adress: http://mtgox.com/code/data/ticker.php

And the content looks like this:

Code:

{"ticker":{"high":1.08,"low":1.0103,"vol":3741,"buy":1.033,"sell":1.0599,"last":1.033}}

Pretty simple huh?

Thanks for your dev

[stakhanov]

Ah, I see, thanks.

I prefer taking the full getTrades.php file, because I compute a time-weighted average rather than the last trade. But I could use the ticker file to display additional information.

[stakhanov]

I've just uploaded a new version. It doesn't show additional info yet, but it should improve the display in some cases, and refresh faster if you turn your computer on and off a lot like I do.

[breandan81]

that's pretty cool, thanks
