Welcome to the world of Edubuntu, a Linux distribution
designed for
schools and other educational environments. Built on the popular
Ubuntu, it is a complete operating system that includes an office
suite, web browser, many educational applications, and much more.
Edubuntu is designed to allow a teacher or network administrator to be
able to setup a complete classroom quickly and easily. Edubuntu is
committed to the principles of free and open source sofware which means
it is free of charge and will always remain that way. Open Source
software aims to preserve the freedom to use, copy, make changes and
distribute those changes. This means Edubuntu can offer higher quality
software at no cost, while allowing everyone to modify Edubuntu to fit
the exact needs of their particular environment.
Edubuntu is comprised of several key technologies, one of
which is
the Linux Terminal Server Project (LTSP) which allows you to boot thin
clients from an Edubuntu LTSP server. For educational environments,
LTSP lowers hardware costs by enabling the use of older machines as
thin clients, as well as reduced administration overhead by having only
to install and maintain the software on the server. When a workstation
fails, it can simply be replaced without data loss or reinstallation of
the operating system.
Any good educational platform should provide applications
specifically for it's target audience and Edubuntu is no exception. For
the younger crowd, just starting out with computers, Gcompris offers a
fantastic early learning environment. For slightly older pupils, there
are a number of games and activities from the Tux4Kids and KDEEdu
projects and for those in high school and older, there is a full office
suite as well applications for instant messaging, graphics, sound and
video. And that is just by default! Edubuntu also includes access to
thousands of other high quality open source programs at no cost.
Edubuntu builds to be a complete and ready to use educational
environment. As such, Edubuntu comes pre-installed with a complete
office suite, teaching and learning programs, pre-school resources and
much more across a range of categories. Here is a brief summary and
some screenshots for the most popular Edubuntu packages, and if you
need more, Edubuntu has thousands of additional applications ready for
you to install.
OpenOffice.org is a complete office suite similar to the
Microsoft
Office suite. It features a word processor, as well as spreadsheet,
presentation, drawing, database, and mathematical formula applications.
OpenOffice.org can open and convert most Microsoft Office documents and
has support for many different languages.
Firefox is the incredible successor to the hugely popular
Mozilla
browser. Amongst its many features are tabbed browsing, which makes
viewing multiple sites a breeze, pop-up blocking, live bookmarks and
great accessibility support. Combine these with its fantastic
customisation engine and you have the most powerful web browsing at
your fingertips.
Moving beyond the simple web browser, Edubuntu also comes with
an
email client and personal information manager, Evolution. Video
conferencing with Ekiga as well as instant messaging and chat with Gaim
provide communications tools that teachers and students need in an
Internet age.
In the graphics deparment, diagrams and flowcharts are a
breeze with
Dia. Xsane provides an easy to use scanner interface. 3D modeling and
animation are Blender's specialty. Image editing similar to Adobe
Photoshop is done using the GIMP. Scribus provides layout and
publishing capabilites similar to Adobe Illustrator.
For all your video and audio play and editing needs, Edubuntu
provides several programs including Rhythmbox for music playing and
Serpentine for burning audio CDs. Sound Juicer rips audio CD tracks to
your computer. Totem is an excelent video and movie player and you can
use Kino to edit video clips. Sound Recorder can be used to record
audio clips to your computer.
Edubuntu is based on, and is indeed dependant on Ubuntu. As
packages
are updated in Ubuntu, they are also updated in Edubuntu, as they share
the same repository. This also means that they both have the same
release cycle, which occurs roughly every six months. You will also
find that many Edubuntu developers are also developers for Ubuntu too.
Of course you can, as well as this document being translated
into
several other languages, there are a few Edubuntu localisation teams
around the world as well as a huge number of Ubuntu localisation teams.
If you think you can help, why not join up to your local team?
Edubuntu is built by a community of people, most of whom are
volunteers. Edubuntu welcomes the advice and feedback from as many
different people as possible. It's what makes this project work. There
is a need for help in every area - documentation, developing, testing,
advocacy, support, so if you want to get involved please do. Just email
the Edubuntu mailing list or join the #edubuntu IRC channel on
irc.freenode.net.
Ok, that headline may be a bit overblown - but Microsoft
Research has released part of a report on the "Singularity" kernel
they've been working on as part of their planned shift to network
computing. The
report includes some performance comparisons that show
Singularity beating everything else on a 1.8Ghz AMD Athlon-based
machine.
What's noteworthy about it is that Microsoft compared
Singularity to FreeBSD and Linux as well as Windows/XP - and almost
every result shows Windows losing to the two Unix variants.
For
example, they show the number of CPU cycles needed to "create and start
a process" as 1,032,000 for FreeBSD, 719,000 for Linux, and 5,376,000
for Windows/XP. Similarly they provide four graphs comparing raw disk
I/O and show the Unix variants beating Windows/XP in three (and a half)
of the four cases.
Oddly, however, it's the cases in which they report Windows/XP
as beating Unix that are the most interesting. There
are three examples of this: one in which they count the CPU cycles
needed for a "thread yield" as 911 for FreeBSD, 906 for Linux, and 753
for Windows XP; one in which they count CPU cycles for a "2 thread
wait-set ping pong" as 4,707 for FreeBSD, 4,041 for Linux, and 1,658
for Windows/XP; and, one in which they report that "for the sequential
read operations, Windows XP performed significantly better than the
other systems for block sizes less than 8 kilobytes."
So how did they get these results?
The
sequential tests read or wrote 512MB of data from the same portion of
the hard disk. The random read and write tests performed 1000
operations on the same sequences of blocks on the disk. The tests were
single threaded and performed synchronous raw I/O. Each test was run
seven times and the results averaged.
umm…
The
Unix thread tests ran on user-space scheduled pthreads. Kernel
scheduled threads performed significantly worse. The "wait-set ping
pong" test measured the cost of switching between two threads in the
same process through a synchronization object. The "2 message ping
pong" measured the cost of sending a 1-byte message from one process to
another and then back to the original process. On Unix, we used
sockets, on Windows, a named pipe, and on Singularity, a channel.
So why is this interesting? Because their test methods reflect
Windows internals, not Unix kernel design. There
are better, faster, ways of doing these things in Unix, but these guys
- among the best and brightest programmers working at Microsoft- either
didn't know or didn't care.
And if they're the best
and brightest, what do you think happens when the average Microsoft
programming whiz gets asked to program for Linux?
The Ubuntu team is proud to announce the Release
Candidate for version 6.06
LTS of Ubuntu, Kubuntu and Edubuntu - codenamed
"Dapper Drake". The Release
Candidated includes installable live Desktop CDs,
server images, alternate
text-mode installation CDs and an upgrade wizard
for users of the current
stable release.
We consider this release candidate complete, stable and
suitable for testing
by any user. We would especially recommend that current
Ubuntu 5.10 ("Breezy
Badger") users and developers use the upgrade procedure
described below.
6.06 LTS will be the first Ubuntu release with long-term
support: three
years on the desktop, and five years on the server.
Upgrade information for Ubuntu and Edubuntu 5.10 ("Breezy
Badger") users
------------------------------------------------------------------------
* Make sure you have good bandwidth since the
upgrade requires
that you download several hundred
megabytes of new packages!
* Because this is the Release Candidate, you need
to invoke the
update manager
explicitly. To do this, press Alt-F2 (or open
a Terminal using Applications ->
Accessories ->Terminal)
gksudo
"update-manager -d"
This step will not be necessary on the
final release.
