Samurai company was developing a pay-per-view system based on a pre-loaded hard-drive. It was initially conceived to work connected to regular PCs running Windows or Linux and the software was being developed in Python.

However, the upcoming start of Digital TV transmissions in Brazil meant that set-top-box equipment would become commonplace and the opportunity to have this system inside set-top-boxes came up.

Solution

Most of the digital tv set-top-boxes in Brazil are running Linux on a ARM or MIPS platform, allowing the usage of what had been already developed in Python by the client.

Triveos:

• ported the interpreter and Python VM to the MIPS and ARM platforms
• ported Python libraries to be used in ARM and MIPS platforms

Comprices was developes for the “Nokia Sem Limites” contest. This app allows people to compare prices between different supermarkets in a collaborative way. The system has a client app that runs in a Nokia S60 mobile phone and a server running on Google App Engine.

In this app, prices have to be filled in when consulting the price of other supermarkets, and are stored for future comparison.

Development

The client app was made with Python for S60 and the server was developed with Python and Django running on Google App Engine. The entire project took 3 days from start to finish.

OnData contacted Triveos in needed of a way to integrate their printing management and billing system (called PrintSystem) to CUPS.

PrintSystem exposes a SOAP webservice that requires print job information (number of pages, username, etc), while returning whether the job is to be allowed or not.

The Solution

Initially, the Tea4CUPS backend was used, having our module as a Te4CUPS preprocessing hook, allowing all document data to be processed before being sent to the printer. However, this was not enough to meet project requirements. Hence, the solution was changed to behave as a CUPS filter as well.

The entire solution was developed in Python.

Customization

After the main project finished, OnData contacted us again to customize the solution for one of their customers. This involved adding business rules and integrating with Novell eDirectory^TM authentication.

Our customer needed a way to rapidly create web sites for their customers in the realty business. They needed a way to provide web sites in a fast manner, integrated with each company’s database, while providing a search engine.

The Solution

An entire website management system was developed, in Python/Django, offering a control panel to an adminitrator (in this case, our customer, the company that contracted the system), and a sub-management control panel, to the company that contracted a website from our customer.

We’re a national reference concerning these tools, actively participating in the developer community and having been contracted to give training on behalf of Nokia and having tutorials published in magazines.

Training

We offer training in Python for Nokia® S60 mobile phones

Real Estate Fair

The customer, for real estate fairs it was promoting, wanted to allow its customers to take a ‘virtual tour’ around places on sale using Google Earth™ in an interactive and fun way.

Proposed solution

Here’s how Triveos solved the problem:

1. A projector shows Google Earth’s screen on the floor, in front of the person that wants to use the system
2. Using a Web interface an operator enqueues the person’s name and the desired place while setting a time limit for the walk.
3. The system asks Google Earth™ to reposition itself over the coordinates corresponding to the first place of the queue
4. The customer then can walk around the neighborhood using a Dance-Pad controller
5. When time runs out the navigation is locked as to wait for the next person in line
6. Customers can also direct the navigation to several tourist attractions and famous places in the world

Technical Characteristics

The application is composed of two modules:

• Queue management system: Uses Python/Django and jQuery for a fully dynamic AJAX interface
• Navigation system: Python/Pygame and integrated with Google Earth™ through COM

This app runs exclusively under Windows

This training is aimed at companies willing to train their employees.
