Installing XEN on Ubuntu 7.10 (amd64)

Posted by suvi under Ubuntu, Virtualization

After finding how-to upon how-to that said to use "apt-get install
ubuntu-xen-server" and repeatedly banging my head against the wall
because it kept telling me the package wasnt found, I finally found the
Xen page at the Ubuntu Community site that explained the situation.
Apparently, there is no such package for amd64 kernels and you need to
specify each needed package. Thankfully, they list the command you need
over there:

(you do need to uncomment the universe repositories in /etc/apt/sources.list)

Prevent Ubuntu asking for the CD to install packages

Posted by suvi under Tricks, Ubuntu

Recent releases of Ubuntu have a feature where the installation CD
can be used as a repository for installing software, just like any
repository on the web.

The advantage of this, obviously, is it means that you can save
bandwidth for some packages that haven’t been updated since the
release, or even sometimes be able to install new packages without an
internet connection at all. The main disadvantage – the CD has to be in
the drive.

Learn OOP while creating 3-D animations with Alice

Posted by suvi under Multimedia

College computer
science students often find it difficult to get started in programming
languages like C++ and Java, largley due to the disconnect between
simple middle-school languages like logo and advanced object-oriented
programming (OOP) languages. To help bridge the gap, researchers at
Carnegie Mellon University (CMU) have developed an OOP language to
create computer animations using 3-D models, called Alice.

Making an Illustrated Book

Posted by suvi under Office, Tricks

One of the things we plan to do
different in the Geek Ranch (see What’s New
Down Here?) is build a lot of domes instead of conventional
buildings. The reasoning behind this is that they are quicker to
build, cost less and use mostly local materials and that which is
not local (in particular, steel) is used in lower quantities than
in conventional construction.

Creating an AS400 terminal with an Old PC and Ubuntu

Posted by suvi under Ubuntu

This how to uses Ubuntu 7.10 Server install. I am sure that this could be done with a much smaller install base, rather than server – I might have used the Alternative CD, or maybe even some other distribution like DSL, or Puppy Linux (if you needed GUI [graphical user interface] ). But for proof of concept this worked fine.  I used an Old Dell GX100 Optiplex with 256 MB of RAM (I don’t think I need any more that 128 [maybe even 64MB], but this is what was in the box when I pulled it out of the pile). It has a small form factor, and runs pretty quiet.

Writing Snort Rules On EnGarde

Posted by suvi under Security

There are already tons of written Snort rules, but there just might
be a time where you need to write one yourself. You can think of
writing Snort rules as writing a program. They can include variables,
keywords and functions. Why do we need to write rules? The reason is,
without rules Snort will never detect someone trying to hack your
machine. This HOWTO will give you confidence to write your own rules.

all kinds of great digital recording gear, from tiny portable recorders
to multi-channel mixer-recorders with CD burners, and Linux has a
wealth of good-quality audio recording and editing programs. The hard
part is figuring out where to start because there is so much to choose
