About this project
Now that its over:
Despite not meeting our collective goal, the work will continue. Please consider providing funds more directly to the project by going here:
The money will be used for the same purpose. I will continue to provide rewards based on the same reward structure with these exceptions. No rewards requiring funds to generate. Specifically, no t-shirts will be provided (I will figure out a way for people to buy them at a reasonable cost later through someone else). Also, anyone who contributes any amount of code or $$ will get listed as a contributor... no minimum.
Ready more about the campaign wrap up here:
In short, it will make Android devices like VERY powerful graphing calculators, but really there is so much more. Simple enough to be usable by anyone and powerful enough to be useful to everyone. This being funded will allow this to become all that is promised and be free and open source for everyone forever.
Going to (more than) port Octave and gnuplot to Android, providing them for free and ad free through the Android Market. This will greatly benefit math, science and engineering students and professionals all over.
If you are not familiar with Octave, check this out: http://www.gnu.org/software/octave/
If you are not familiar with gnuplot, check this out: http://www.gnuplot.info/

If you are wondering, a sombrero is the image you see as the project logo (not just a hat). It used to be the logo for Octave.
- Octave working on Android built with all required dependencies packaged as a free and ad free app in the Android Market.
- gnuplot working on Android built with all required dependencies packaged as a free and ad free app in the Android Market.
- Source code published openly.
- Push changes back as patches to Octave and gnuplot development teams after they are stable and debugged.
- Basic touch interface that looks like a terminal for Octave port. Basic m-file editor.
- Basic touch interface that looks like a terminal with additional plot windows for gnuplot port. Plot windows are not interactive at this stage.
- Octave and gnuplot ports hooked together through a socket (of sorts).
- Support, bug fixes and feature requests (won't grant all feature requests of course).
- All optional dependencies built into Octave port that are built into Octave releases.
- All optional dependencies built into gnuplot port that are built into gnuplot releases.
- All packages built into Octave port that are built as part of Octave-Forge releases. Reasonable way to add packages to device.
- Better touch interface for Octave port. Including fully debugged customized keyboard, significantly enhanced m-file editor, variable viewer/editor and history viewer. Various settings/preferences that will allow you to customize the look and behavior of the app.
- Better touch interface for gnuplot port. Including intuitive zoom, pan, etc.
- Prove interfaces across a range of screen sizes and other device parameters.
- Provide intents for other applications to take advantage of the capabilities provided. Meaning other apps can use these as their plot or math engines.
- Put all libraries and executables that this project is dependent on in an easy place for other developers to grab.
- Provide the standalone toolchain necessary for repeating this work by others. It is the NDK toolchain with modifications.
- Provide scripts that make updating which version of Octave is used under the hood is used easier.
- Blog about interesting issues encountered or lessons learned along the way.
- Port upcoming Octave use of OpenGL for plotting to Android.
- The sky is the limit...
If we get past the funding limit, exciting features will be added like reading sensor data for use.... Think of all the fun physics experiments you could perform.
When do I plan on getting there:
Fall 2012 - Octave, gnuplot mostly ported with basic interface in place.
Fall 2013 - all deliverables.
How obtainable this is and how quickly this actually occurs depends a lot on you.
How do I plan on getting there:
As mentioned in the project videos, I already have a release proof of concept of Octave running on Android. It can be enabled from the Settings->Preferences->Enable Experimental Interpreter option in the app called Addi, https://play.google.com/store/search?q=pname:com.addi . I also have a proof of concept of gnuplot built for Android running locally (there is some work to do on the interface before that can be released). But, going from a proof of concept to a finished application with all the deliverables listed being met is not a small task. Now that I have the proof of concepts finished, along with some other experiments I have done to prove feasibility, I can focus on driving towards completing the deliverables listed. The rate depending on the funding received, I will focus time and work through the list, providing releases at key points in development. Time will be set a side for support, bug fixes and some feature requests.
Why $50,000 dollars:
The reality is I am working on this project anyway. I am passionate about it and will achieve many of the deliverables over time regardless. What the money allows me to do, is to make some work/life changes to make this happen at a much accelerate rate, with higher quality and better support. Kickstarter is also an all-or-nothing program. If you don't meet your goal, no money is transferred. So, $50,000 is the minimum necessary for me to make changes that will noticeably improve the trajectory of the project. Ideally, we will hit a number that is much higher than this, which will allow this to become something truly awesome. Anything above the goal will be used for this project. Nearly all money will be used to pay for development time. I hope people find as much value in this as they have for funding some recent games on kickstarter, if so, this will be something truly great.
