dangerously curious bitcoins

Some things you find on GitHub are more interesting and frightening than others.

This one is both and some more. What is it you ask?

R2 Bitcoin Arbitrager is an automatic arbitrage trading application targeting Bitcoin exchanges.

So it’s buying and selling Bitcoins. And it’s doing this on different markets.
On the topic of arbitrage Wikipedia has something to say:

In economics and finance, arbitrage is the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices at which the unit is traded.

For example, an arbitrage opportunity is present when there is the opportunity to instantaneously buy something for a low price and sell it for a higher price.

Now this already is the second version of the tool and already 2 years old. See it as some sort of interesting archeological specimem. Please refrain to actually so something harmful with it.

I am writing this down here because apart from it’s obvious horrors this is a good starting point to understand how these computer-trading-systems do work in principle.

Given that an architectural drawing is also included it gives all sorts of starting points to thoughts.

Also. What could possibly go wrong if a tool to buy/sell on actual markets with actual bitcoins is confident enough to include the “maxTargetProfit” configuration option. Effectively setting the top-line of profit you’re going to make!!!111

where is the heat? – click-track your weblog…

AJAX is the key to rich web applications. And finally someone bridged the gap between click-tracking and those rich web applications.

With “Crazy Egg” is is possible to track the users of any site right down to their clicks…how cool is that (well if the users-webbrowser is configured to allow that) ?

Mashable.com was able to test it on their website…which looks like this:

After one our Crazy Egg created this heatmap…showing where the users clicked the most…

4500mAh battery for the HTC Himalaya / MDA2

Mhhh… I NEED to get one of those. But $140 is quite a bit if you can get a 1200mAh battery for less than $20.


“With normal usage it was 70.5 hours real time duration before I reached the 10% minimum level at which I needed to put it back on charge, that’s a predicted total of over 75 hours duration and a Pocket Plus measured usage of almost 19 hours – Wow!”

Emma’s Mini: Beat Generation Mad Trick

On my proceeding mission to evangelise the world with great music I have something for you. It’s even more than just music: it’s a seminal way of buying music. But from the beginning: First the music.



Emma’s Mini: Beat Generation Mad Trick


It’s actually the first album of Emma’s Mini. And it’s not brand new because it came out in 2003. But it’s exactly what I had in mind that very moment I found it. I only heard one song and I bought the ablum straigt away. And I did not regret it. It’s cool. It’s innovative. Fits perfectly in my collection and will fit even more perfect in yours.


Because maybe the fewest will know Emma’s Mini already, here’s a short info on them:


“emma’s mini is a duo based in Seattle, WA. They first started making music together in March of 2002 and in April of 2003 they self-released their first album, beat generation mad trick.


Taking their cue from bands such as lamb, Massive Attack and Moloko, emma’s mini is creating a new and exciting sound, seamlessly blending Suzanne McClean’s rich, lush vocals with Demian Shoemaker’s innovative beats and soundscapes.”


And indeed: Suzannes voice is great… and “soundscapes” is the word I also would have chosen when I should describe the music itself… Infact: Go and hear the complete album. And more important: If you like it, buy it! It’s really worth the money. (what a great transition…)


Emma’s Mini is not under contract at a major label. Infact they are – as far as i know – not under any contract. But they sell their music through Magnatune.


And Magnatune describes itself that way:


“We call it “try before you buy.” It’s the shareware model applied to music. Listen to 356 complete MP3 albums we’ve picked (not 30 second snippets). We let the music sell itself, because we think that’s the best way to get you excited by it. Our selection is intentionally small: we never waste your time with mediocre music. If you like what you hear, download an album for as little as $5 (you pick the price), or buy a real CD, or license our music for commercial use. Artists keep half of every purchase. And unlike most record labels, our artists keep all the rights to their music. No major label connections and no venture capital. We are not evil.”


And they mean it. You can choose how much you would like to pay for the music…from 5 bucks upward…that’s great because you get the music without DRM or any other limitation… You even buy the exploitation right on the tunes… How cool is that!?



Magnatunes recommends a price…but you can change it easily, preferably upward.. ;-)

wie A9 die Yellow Pages gemacht hat…

A9 bietet ja seit neuestem in seinen Yellow Pages auch Fotos der Strassenfronten der Geschäfte in den Yellow Pages an. Und sie verraten auch, wie sie das gemacht haben. Nämlich mit speziell ausgestatteten Autos – ausgestattet mit Kamera+GPS+Notebook. Geniale Idee!



“Using trucks equipped with digital cameras, global positioning system (GPS) receivers, and proprietary software and hardware, A9.com drove tens of thousands of miles capturing images and matching them with businesses and the way they look from the street.”
