Snapshots
some of my side projects
Template2Pdf
Is a SAAS-API that fell out of some other project of mine.
I was in need for a "user generated template to pdf" solution and this is the result.

Datajones
My first experiments with html5 offline storage. Datajones allows the user to define and generate a form.
This form can now be used inside a mobile phone to collect data sets. Once the phone has a data connection,
the collected information get uploaded to a server, where they can get fetched as spreadsheet.

AaaRails
This software provides a REST like API to fill a database used by a aaa/radius
server with rather complex profiles while
keeping the payload of the api-calls as simple and human readable as possible.
It provides a basic web interface to setup templates and for manipulate of profiles.
Tested and running with the standard Freeradius 3.0 schema for Postgres.
Probably easy to rewrite it for other aaa servers.
It is open source: https://dev.beastiebytes.com/root/aaarails/
Caluanda
Reservation software.

Bored-Bookworm
Just a small website that buys me a present each year.
Mainly build to play around with the twitter and amazon APIs.

OpenAbacus
I wanted to play a bit with the HTML5 offline storage options.
Openabacus is a html5 application that allows you to put mathematical
formulas into your mobile phone for quick access.

Corillo
Community software for fitness clubs.

Ipop
Ipop is a small ERP system, with focus on easy integration with other applications.
It has modules for bookkeeping, workflows, sales and HR needs,
but is designed to delegate those tasks to other systems.
It is used to sell SAAS, setup accounts and access permissions.
It sells VSAT systems, access to wireless hotspot networks, various other
services and products. It configures access to NMS systems and displays
information from various sources.
