Welcome to cd3wd.com latest version, which comprises approximately 54 x 4.33 GB disks plus 6 partial bit and pieces (about 211 GB in total).
From today 15 August 2012 over the next weeks and months we will be uploading the content whose listings you can view below - apologies for these delays -
it is a massive amount of material and bandwidth, cost and connection quality here in Botswana Africa is not really up to the job - so we have to
courier external hard drives to our volunteers in high-bandwidth countries for them to upload to our website. BUT - meanwhile - we ARE ready to airmail free dispatches to
Third World country destinations and we can sell also the disks commercially - which we are pricing at US$ 6 per packet of 2 disks.
What is new and/or different? If you have the 2011/12 version already then the disk 1006 will upgrade its core material to the latest version (the core material is disks #1001 through #1006 -
6400 core titles).
Otherwise there are 2 main differences -
there is now significant formal educational material - for preschool (#100212), primary-plus-junior-secondary (#10028), for senior secondary (#10029), and for tertiary (#133).
There are also past exam papers (#136 and #137) and an excellent encyclopedia (#10035 - which we are only doing as an airmailed disk, since it can be downloaded from
). There is also a range of DVD-player disks - #10063, #10064, #10065, #10066 and #10071 - which mean that billions of people who have no computer
but who do have a DVD Player and a TV (or a TV with a USB port) can utilise digital content! This is such a significant and huge step forward, which the Aid and Development community as usual is doing its utmost to ignore... These disks cover about 30% of the core material from disks #1001 through #1006, and over time we can increase that to 100%. The 3 disks #100212, #10028 and #10029 already run 95% of their content on both computer and also on DVD Player, not to mention all of the preschool stuff on mobile phone.
Also there is a special medical disk
which combines computer and DVD player material, in view of the importance of medical and health material.
And we have downloaded and processed 99% of
KhanAcademy.org material and created 31 disks of instructional videos which are also on this website for downloading. These disks run on PAL-system DVD Players with no extra work or conversion - i.e. they are immediately useable by the billions who have DVD Player but no computer. The disks are grouped by subject and can be provided or sold on a standalone- or small group basis. They will also be ideal for operation through general purpose or through dedicated DVD Hire Services or Libraries (e.g. with US$ 0.25 per disk deposit, forfeited if disk is scratched on return).
Keep an eye on this website and also 'like' our
to get automatic updates. We will also probably start a google group for those who cannot or are not allowed to access facebook - that group will contain a duplicate of most or all of the facebook stuff as it is issued.... We welcome contributed material which is not copyrighted (we will even welcome handwritten material), and we welcome donations and sponsorship...
Note that our website
will be used only for microdownloads and for browsing.
Microdownloads can be of one, several, many or even all pdf and/or zip files, and can best be done by using Free Download Manager, which is downloadable from the web.
We will produce and provide .csv and text files to assist in that process. Microdownloads are the only feasible download method for almost all Third World locations, where
downloading 4.33 GB chunks is and will remain a dream for many years to come. Note that the DVD Player titles jpg files are offered for microdownload in zip files - one zip file per title - with average size about 20 MB (400 pages).
We no longer offer direct downloads of disks nor do we ourselves organise torrent downloads (but others are welcome to organise and host torrents using our material). But do not worry - you can download everything or as much as you want using microdownloads with Free Download Manager as immediately above. We encourage friends of cd3wd to do microdownloads and then to re-upload to their own websites and host parts of or even the complete cd3wd in parallel to ourselves. We will provide links to all these parallel sites. This creates a more sustainable model and keeps our data traffic allocation from exceeding our monthly limit (which then costs us money. which we do not have). If you do not already have a website, we would recommend
Brinkster Web Hosting, who very kindly give us their $36/month package for free. Their US$ 6.99/month package is particularly good value, giving 200 Gb space and 2000 GB per month web traffic.
