The Dutch Debian Distribution Initiative is a Chamber of Commerce registered firm that since ca. 1997 (in various forms) is aiming towards the ongoing distribution of the Debian GNU/Linux Operating System on a low-profit basis.
The DDDI is being operated by the two brothers Anne and Maarten Bezemer, Delft University of Technology engineers (Master degree) in, respectively, Electrical Engineering and Technical Informatics, with a very wide interest in everything having to do with electrical currents. These days, they are entrepreneurs and occupy themselves with all kinds of IT and telecom related affairs, in which Debian plays an important role.
The CDs and DVDs we provide are Recordables (CD-Rs and DVD+/-Rs), that we burn ourselves on customer request. For series of up to a few thousand items, this is cheaper than having them manufactured by a CD/DVD production company. Furthermore, since we keep no stock at all, official updates can be applied very quickly.
The brand of media varies, as we are continuously searching for the best quality media at an acceptable price. This way, it may happen that two subsequent identical orders are delivered on different brands or types of media.
We currently burn CDs and DVDs using two NEC ND-3551A writers. CDs are usually written at 16x speed and DVDs at 12x speed, as this has proven to give the best results for most media brands.
Prior to shipment, all CDs and DVDs are completely checked for readability with an extremely sensitive LiteOn CD/DVD drive, which enables us to remove all less good CDs/DVDs from the series.
The content of all CDs and DVDs labeled "Official" comes directly from http://cdimage.debian.org, the site on which the official Debian CD and DVD images are published. The "Unofficial" CDs/DVDs originate from other sources.
The website of the DDDI forms a complex unity with the back-end programs. All aspects of it were developed in-house. Next to an efficient system for production planning, there is a direct interface with gnucash for accounting purposes.
As far as necessary, the webpages use 'POST' requests to transfer data to the CGI programs that generate dynamic pages 'on the fly'. No Java[tm] or 'cookies' are used, which makes all pages work in any browser.
All CGI programs are C programs that use the cgic standard library. The database used is a Berkeley db2 type with binary tree indexing. The records contain a fully recursive data structure of arbitrary length, which eases programming considerably.
The total size of the C code is more than 8000 lines. The code is completely internationalized; at the moment there are English and Dutch language libraries of about 70 kB text each.
Very limited warranty
Because we don't want you to blame us or the Debian project, we do our very best to prevent and (if at all possible) resolve any problems. But because we use many services of third parties, for example postal services, we can only offer a very limited warranty, solely on things we do ourselves.
Therefore we apply the following rule:
If any customer is unable to read a CD or DVD provided by us in
his/her CD-ROM drive of at least 24x speed or DVD-ROM drive of
at least 8x speed, respectively, AND we can (still) read that CD/DVD
after return shipment, then a free replacement CD/DVD will be shipped to
that customer. For the first replacement CD/DVD, this rule is
applicable as well. As usual, the return shipment of the 'unreadable'
CD/DVD is to be paid for by the customer.
(The second condition is necessary to exclude any possible transport damage, which is not covered by any warranty. Still, the applied packaging materials virtually guarantee undamaged delivery. As noted above, we only ship CDs and DVDs that we can read ourselves.)
In all other situations there is NO WARRANTY WHATSOEVER, namely as detailed here:
THERE IS NO WARRANTY FOR ANY PRODUCT, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EVERY PRODUCT IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF ANY PRODUCT IS WITH YOU. SHOULD ANY PRODUCT PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW WILL ANYONE BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE ANY PRODUCT (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF ANY PRODUCT TO (INTER)OPERATE WITH ANY OTHER PRODUCT OR ITEM), EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
This also means that we do not accept any liability if the postal service does not deliver a package. However, in practice, there hasn't been any problem with this. On request, we can organize insured (registered) transport of the packages. However, this means so much more work for us that we will charge EUR 13.00 extra per package. A request for insured (registered) transport must be made using the comments facility when placing the order. We will then adjust the total price manually.
