A Telematics Discussion

Don’t miss this very interesting Telematics Discussion on TFF’s blog (telematics Freedom Foundation). It really worths a reading.

Free Telematics: a model for the democratic control of telematic services

April 25th, 2007

It is not enough for citizens to be told to have certain rights as users of a given telematic service, under a license (such as FLOSS), or a legislations (such a national and global privacy protection regulations) or under a contract with the service provider (such as Terms of Use)
To actually control a telematic service, or a web service, a user needs reasonable practical means to verify the software AND the hardware of all servers which run at and beyond the point of decryption of my communications with such service (or “end servers”).
If such “end servers” interact with other external network services, I will know, by having access to their code of the “end servers”, which services, and all the details and conditions of such interaction.
It is not necessary to control servers and networks in between the client device and the “end servers”, as we can reasonably rely on the power of the latest encryption to totally secure from all software, hardware and cables in between. In fact, the communication could be intercepted in between, but the content could not be read. It could be stopped or deviated in between, but there is free software that, installed on both client and server can prevent that, or at least verify that it did happens.
This is not new. Democracies, for centuries now, have always provided citizens with reasonable means to verify that key constitutional rights were not widely abused. When I go to vote, I do not simply have the right that my vote be secret and fairly counted, but I rely on a good number of other citizens, randomly selected or with conflicting interests, which prevent the bad guys to put in place large scale abuses of such rights. There are also a number of process regulations, such as recounts, that further prevent such frauds.
In fact, in order to provide such concrete control over telematics, server rooms (or “cages”) hosting a such “free” telematic service could be physically managed applying those same (or enhanced) physical security provisions that are currently applied to ballot boxes during an election. In practice, physical access to such servers would be enabled only while a few randomly selected or elected users (or citizens) are physically present. For a more detail explanation on how that may be accomplished, see our proposed hosting requirements for such service
According to this model of telematic service provisioning, anyone could deploy a “free” telematic services, by developing new software or freely installing or extending any publicly available FLOSS software, and running those according to such hosting requirements.
Anyone can do this, without breaching any FLOSS license, by requiring the signing of a copyright assignment, or similar statement, whenever users, or anyone, wants to access the software source code.

For more info on how set up such “free” telematics service, see our draft Service Access Policies at

TestableEmailer – Enables you to write automated tests for emailing functionality

May 31st, 2006

Let us say that you have an application that includes an e-mail notification system. Essentially when certain application specific events happen, certain users are automatically notified by e-mail about these events. We have such an application and wanted to include the e-mail verification as part of the accepance test-suite.

TestableEmailer is a product that grew out of this need. It is a thin wrapper around MailHost that allows for a “test mode”. When this mode is turned on, rather than sending the mail through the Mail Host the product stores all the information in the email. This can be retrieved later and assertions made against what is expected from that e-mail.

TestableEmailer has been built using Five interfaces and views. It has been tested on Zope 2.8.6.

Get the product here.

Ever wanted to allow users to upload more than one file as an attachment to a document, akin to Gmail’s web interface?
The new Multifile Widget will allow you to do that. The picture below should illustrate how the widget works.
