[DDN] comparison of video blogging compression techniques

2006-04-25 Thread Andy Carvin

Hi everyone,

One of my video blog viewers asked me for an explanation of various 
quicktime compression techniques I use to make my online videos smaller 
for different audiences. I've just published my response:


http://www.andycarvin.com/archives/2006/04/andys_video_blogging.html

In this demonstration, I start with a 10 megabyte video shot in avi 
format, 30 frames per second, 640x480 pixels, 16 bit stereo. I then 
produced seven compressed versions of it, including ones that utilize 
varying frame rates, screen sizes, compression codecs, and audio 
compression.  The most compressed version I created is 97% smaller than 
the original avi video, and is potentially quite suitable for video 
blogging in low-bandwidth situations around the world. Some examples:


Original uncompressed video (10 megs):

Significant compression (1.8 megs, 82% reduction):
http://www.andycarvin.com/video/demo-3ivx.mov

Extreme compression (292 bits, 97% reduction):
http://www.andycarvin.com/video/demo-3ivx8bit160.mov

Here's a chart featuring all of the videos and their settings:

Anyway, I hope this is useful for those of you exploring the world of 
video blogging.


thanks,
andy

[DDN] Open Source Computer Asset inventory/help desk application

2006-04-25 Thread Kinyua Martin
Dear All,
 
I am looking for an open source computer asset management/helpdesk
application that I can use within my project. I have some that I am
evaluating (mainly from sourceforge). Is there anyone out there who has
successfully implemented a computer asset management application? I
would be interested in comparing notes.

[DDN] COUNTRIES: NIGERIA : LIBRARIES: Nigeria: Nigeria's Library System: Is It Collapsing or Transforming?

Nigeria: Nigeria's Library System: Is It Collapsing or Transforming?

Economic and global technological developments, most prominently,
Information Communication Technology (ICT), are having tremendous impacts
on Nigeria's library system, portraying it as collapsing or transforming,
depending on the conception and perception of the traditional values and
functions of library one holds.

The impact of each of these factors depend on and vary according to the
nature and statutory functions of each type of library in the country's
development system. More striking are developments in the libraries of
universities and higher institutions and the national library.

The current situation of university libraries, for example, is partly
deplorable due to the depreciation of the value of the country's currency,
the Naira, in foreign exchange, and the virtual paucity of funds for the
regular acquisition of hard copies of materials - textbooks, journals and
all other necessary research and learning materials; and partly
gladdening, due to the transformation they are undergoing from their
age-old essentially hard-copies form, to the electronic or digital form,
thanks to the ICT.

In the entire library system, university libraries have better funding
generally. They were well funded previously by the National Universities
Commission (NUC), Professor Doris Bozimo, the Ahmadu Bello University
Librarian, recalled, lamenting, But because of this foreign exchange we
are now experiencing, we find that whatever amount of Naira we have, by
the time we change it to Dollars or Pounds, we get very few books, and
right now, there is very little funding for university libraries, because
Vice Chancellors are not even able to pay salaries.

Complaining passionately of very little funding, she admitted that
university libraries in the country now, do not take normal delivery of
books and other volumes because generally, funding for the universities
has dropped drastically. So a lot of their libraries do not have the
resources to buy the books. 95% of the books universities use are
imported, and we don't have the funds to buy them. Very few university
libraries now buy books from abroad, because the resources are simply not
there. We have some books online, but they are very few.

[DDN] Drupalib: a place for library druplers

2006-04-25 Thread Phil Shapiro
hi Digital Divide Network community -

 i first learned about drupal from DDN member taran rampersad. drupal is a
very flexible and powerful free content management system (CMS.)

see http://en.wikipedia.org/wiki/Drupal

  for those of you who work in libraries, here's a new web site for library
people interested in use of drupal.  

  this message below is from the web4lib email list.

Hi,

I've set up a website for people who are implementing, or who are
considering implementing, the Drupal Content Management System in
libraries. Drupalib (http://drupalib.interoperating.info/) is intended
as a place for Drupal implementors to share ideas, configurations,
themes, and maybe even to incubate the development of some modules that
allow commonly desired functionality in library websites. It's based
roughly on drupaled (http://drupaled.org/), and features a blog, a
forum, and a listing of drupal sites implemented by libraries.

Correction Re: [DDN] comparison of video blogging compression techniques

2006-04-25 Thread Dave Pentecost
Hi Andy

Others may have caught this. But you got my attention when your post
listed the extreme compression example as 292 bits. Wow! Actually, I
show 288 kB once I downloaded it.

Good work!
