Bitcoin Cart - Free Shopping Cart for AppEngine

I am pleased to announce the official beta version release of the shopping cart application I have been working on.

I have fallen in love with bitcoin, and wanted to create a new shopping cart option for people looking to sell online using BTC. It is also integrated with google checkout as an alternative.

The suite calculates shipping prices via Fedex, and calculates the smallest size box needed for a given amount of interior boxes.

This software is totally free, and I just ask for a small percentage of your bitcoin sales as a donation.

Bitcoincart deploys to Google's Excellent AppEngine infrastructure. If you are not familiar with Appengine, it is very easy to setup and use... Also it is free for low traffic sites. If you need a hand getting it set up, get in touch! edcolmar@gmail.com

Real Estate Business Card Design

One of my designs was featured in a "design inspiration" blog post showcasing some really really nicely designed business cards.

Butterfly mining

This is a short video that Amna and I just finished.

It is for a competition sponsored by butterfly labs for one of their new ASIC based bitcoin mining devices.

Butterfly Mining from Ed Colmar on Vimeo.

We shot the footage at cherry creek, near Silver City NM.

I composed all of the music in Renoise. This was the first time I composed the music starting with the video footage. As opposed to writing a piece of music and forcing the video to match.

Editing was done in Sony Vegas, with a little bit of help from Illustrator for the type.

This is a remix I just completed of Jason Snell (Bombardier)'s new techno track "Nemesis".

Signal Peak

This is a new original track.

This one I suppose I would call hard techno, even though it does not fit the normal "four on the floor" rhythmic style. In fact, the second half of the piece is 6/8. It is 140 BPM. It is hard. Therefore it is hard techno. =)

I had a lot of fun with this one, and it deserves to be played loud.

I also made some ringtones out of some of the components.

From the archives: Complete Sets from Trust Replicate 2002

My recent experience with the Raspmc media center led me to the mixcloud plugin, which is great!

So, I decided to adopt mixcloud as my official repository for dj sets.

Here is the complete archive from the Trust Replicate 2002 camp out.

The video gives an overview of the event, and complete sets are found on my mixcloud page.

Enjoy!

Encrypted communication over the web with App Engine

I took on a project for an international environmental and human rights organization recently. They needed a way to communicate over the web using private, anonymous, secure methods.

I decided on the DOMcrypt firefox extension to handle the encryption. Big thanks go out to David Dahl for spearheading the effort, writing the extension, and providing near real time support for questions and bugfixes.

The site uses appengine's ndb for storing public keys, user contact lists, and encrypted messages. https is enabled and required. Users are encouraged to browse using TOR to further enhance security and anonymity.

Users are further encouraged to download the package and run separate isolated instances of the code to completely segregate themselves from a "primary" communication site.

This is being released as an open source project, and I welcome any and all comments and critiques. Please feel free to use it for your own encrypted communication needs.

The demo lives here, and contains links to all source code:
