Working on Ghostnote which is a contextual notes & todo app. It allow you to add notes to Folders, Files, Applications, Documents open in applications and even URLs. Don't think there is anything like it out there. It will look kind of like this: http://grab.by/xJIG

Huh? That link shows a 404, and ghostnote.com seems to be a drum enthusiasts community.

Sorry I was an idiot should be fixed now.

SiteBox -- for website in a box -- is software that will allow users to quickly create a website. Think of it as wordpress.com but where each site has an integrated wiki. SiteBox uses markdown as its markup language.

People will also be able to run SiteBox on their own PCs to use as a personal wiki. Or to have offline backups of wikis on the net that can be easily resynced.

People will be able to collaboratively write a book using SiteBox. It will have version control, possibly using git with an easier user interface.

SiteBox will also have privacy-enabling features: people will be able to run it locally (on a PC or a Raspberry Pi) to communication using email and a collaborative wiki, and all communication over the net will be encrypted.

4 days ago I launched my first iphone app (Ticket Titan App). https://itunes.apple.com/us/app/ticket-titan-app/id838769146...

As a law firm we are only handling Florida, but as of now you can pay your tickets (traffic, parking, red light camera) or hire our firm to defend you. The future is much more interesting where we are seeking to become a niche search engine, whereas you will just take a picture of your ticket and the results will be attorney who practice on the jurisdiction filtered by their fee for that charge.

ZynAddSubFX - an open source synthesizer which due to some architectural flaws has spawned the need for a subproject of librtosc which is a hard realtime safe implementation of the OSC serialization protocol and a dispatch system to go along with it.

I'm working on a document-oriented database engine written purely in Python: BlitzDB! https://github.com/adewes/blitzdb My motivation was that I needed (wanted?) a pure-Python document database that does not have any dependencies (like pymongo) and provides querying capabilities similar to MongoDB. Currently, Blitz is under active development and comes with a file-based backend as well as a MongoDB backend. Contribut…

When this is used with a mongoDB backend, how much slower is it than just using pymongo?

It depends ;) It's a very thin wrapper around MongoDB, so normally the performance penalty should not be too large. The biggest slowdown will come from inspecting a document class to see if other document classes are contained within it (which will be replaced by DB references).

I've been writing an algebra editor. It automates much of the details of doing maths while letting you select or move equation fragments. It has been designed around solving back-of-the-envelope calculations so it starts and runs quickly, it's cross platform (a single executable Java *.jar file) and open source (http://sourceforge.net/projects/ket/). Once you get good at computer programming or maths on paper, problem solving becomes relaxed and automatic. Hopefully the same is true of Ket.

Just as you would write an essay by repeatedly redrafting it, real-world maths problems often require as much effort be put into understanding and clarifying problems as are required to solve them. And yet existing maths programs assume you know the question and need only break it into a series of standard steps (integrate, solve etc.) and leave the details to the computer. When doing maths on paper, you learn to recognize fragments and how to move them around. The intuitions are quite different.

The user interface lets you add functions and symbols which can alternatively be written in plain text, e.g. "sin(\alpha)^2=sqrt(x)". Equations are viewed in conventional mathematics notion and are updated quickly and smoothly. Click-and-dragging equation fragments lets you solve or substitute for variables and - with practice - perform algebra by various keyboard shortcuts.

Nothing as interesting as many of the projects here, but I've had around 10k visits this month and plenty of returning visitors, so I guess it's useful enough.

It's a very simple generator for static social media sharing buttons with support for Font Awesome: http://simplesharingbuttons.com/

Quite useful for mobile websites or email newsletters.
