babysign
DATE: | 17th September 2011 |
TAGS: | iOS iPad iPhone JSON |
DESCRIPTION: | This babysign app is designed to show you how to sign with your baby. This contains over 300 signs to enable you to communicate with your baby prior to speech.
Available for the iPhone, iPad and iPod Touch, we also have footage of our amazing babies using signs in everyday situations. The benefits of babysign are manifold so we will tell you just a few: *Communicate before your baby can talk using simple easy to learn signs *Enhance the bond between you and baby *Encourages earlier speech and increases spoken vocabulary *Can increase IQ by around 12 points *Gives your baby confidence! *An added bonus is that the signs are based on British Sign Language so not only will you be learning something fun you will also be learning a new language for yourself. We are sure you will be glad you are a babysigner! |

Tube Tracker
DATE: | 31st May 2011 |
TAGS: | API Core Location CSS Full Website iOS iPad iPhone Javascript jQuery JSON PHP Python |
DESCRIPTION: | App Store statistics:
A multi-platform live departures application for London Underground and DLR trains. Q. What advantages does your app have over other Tube apps? All of the apps on the App Store do not do anything more than either relay TfL's API data, scrape TfL's website or scrape the DLR Daisy website. Although these are the best sources of information, they only update (roughly) every 30 seconds, and the data is often incomplete or malformed. We have a server that collects all of the information from the API (i.e. every station prediction/summary) simultaneously, and the information from DLR Daisy. As the stations don't get updated at the same time, but contain redundant information, we are able to get fresh information every (roughly) 5 seconds by piecing all of the predictions together. We also do a lot of other stuff, like:
Innovative train details screen - shows each train's stops, including how many minutes to each station. Works on all versions (including first generations) of iPhone, iPod Touch and iPad. No need to purchase separate versions! We also have a web version at TubeTracker.co.uk |

Latin Squares
DATE: | 16th April 2011 |
TAGS: | API C++ Git iOS iPad iPhone JSON |
DESCRIPTION: | A Latin square is an (n x n) grid of cells. Each cell contains exactly one symbol from the set S = {1, 2, ..., n}. If you look down any column, or across any row of the Latin square, you'll see every symbol precisely once. If you've ever completed a Sudoku puzzle, then you've built a Latin square on the symbols {1, 2, ..., 9}.
This app provides comprehensive coverage of the field of Latin squares, including: * Theory, * Books, * Journal articles, * Unsolved Problems, * Notable Latin squares It also includes a random Latin square generator (using a Markov chain pioneered by Jacobson and Matthews' Markov chain in 1996). You can generate Latin squares for any order up to 11. Once you have generated a square, you can then find transversals that lie within it (if there are any). The app will be updated with new content as and when it appears in the community. It has been built as a universal iOS app, so it will look good on an iPhone, or an iPad. It also demonstrates a custom class that I built: the CUIHorizontalPickerView. Additionally, all of the content, and even the navigation structure, is read in via an API, so the app can be updated without having to pass through Apple's approval process. All of the source, which is Objective-C++, is available from my github page. |

Strings
DATE: | 1st March 2011 |

DesignMC
DATE: | 18th February 2011 |
TAGS: | GAP Git |
DESCRIPTION: | A GAP Package to generate uniformly distributed random 2-design with block size 3. This code, which heavily utilises L. H. Soicher's DESIGN package, is a GAP implementation of an extension of Jacobson and Matthews's 1996 paper Generating Uniformly Distributed Random Latin Squares.
Once you have loaded the package, you can play around with generating some uniformly distributed 2-designs in the following way: gap> a:=LS(10,1); |

Curatr
DATE: | 29th August 2010 |
TAGS: | API iOS iPad iPhone XML |
DESCRIPTION: | NOTE: This app has been replaced by "Curatr for iPad"
Curatr was made with the new generation of smart touch interfaces in mind When you are properly engaged in a Social Learning experience you need to get access to your community wherever you are; its why we made Mobile a key feature of Curatr from the start. For Apple devices, such as the iPhone, iPod Touch and iPad, we have developed a specialist App which your users can download and install. The App presents users with a bespoke interface which is both intuitive and innovative. Our unique visualisation approach makes it easy to handle huge amounts of information, even on the small screen. For Android devices, Curatr works out-of-the-box. As Curatr is a Flash application, your phones (from version 2.2) are ready-made Learning Environments when coupled with Curatr. By allowing your users to Connect with their learning community on the move, you bring a whole new world of utility to your Learning. The app is somewhat updatable without resubmitting to Apple as the content is all retrieved from our API. |

The Maths Site
DATE: | 1st January 2005 |
TAGS: | CMS CSS Flash Full Website Javascript MySQL PHP XML |
DESCRIPTION: | In 2004, I began studying for a degree at Queen Mary, University of London. Like most people, I found the jump from A-levels to degree level quite tough and during this time I was always on the lookout for ways to get involved with my peers to ease the transition. There were plenty of academic activities to join, such as PASS, and many of the faculty members were always approachable and available for a chat should one require it. However, I still felt that there could be more - a way to bring groups of friends together to chat about both academia and their social lives, maybe even play games, so I got to work on building a website to rectify this.
The website features all the latest mathematics news, a collaborative blog by lecturers, a book shelf, a list of courses and course information, a bespoke forum, puzzles, games, podcasts and videos. There is also a full, custom-built CMS too. |

Forum Demo
TAGS: | CMS CSS Full Website Javascript MySQL PHP XML |
DESCRIPTION: | This is a forum that I coded from scratch. It has everything that you'd expect from a forum like the ability to create users with different privileges. For example, some users cannot see certain topics, maybe some users can edit or delete posts etc.
Posts may have attachments (as many as they can fit in 8M), polls and emoticons. Also topics can be locked or pinned to the top as well as split in to two topics, or merged in to one. This is the forum that I used in creating The Maths Site. |
