Service discovery on a local network

What is Avahi? ¶

Avahi is a system which facilitates service discovery on a local
network. This means that you can plug your laptop or computer into a
network and instantly be able to view other people who you can chat
with, find printers to print to or find files being shared. This kind
of technology is already found in Apple MacOS X (branded Rendezvous, Bonjour and sometimes Zeroconf)
and is very convenient. Avahi is mainly based on Lennart Poettering's
flexmdns mDNS implementation for Linux which has been discontinued in
favour of Avahi.

Screencasts on Linux Made Easy

Nov 19, 2008 6:10pm GMT

Dmitri Popov

Need to create a screencast to demonstrate an application feature or
nifty software technique? The easiest way to do this is to install the
recordMyDesktop screen recording utility and the gtk-recordMyDesktop
graphical front-end to it. Most mainstream Linux distributions include
both packages in their repositories, so you can quickly install them
using your system's package manager. On Debian-based distros like
Sidux, installing both packages is a matter of running the apt-get install recordMyDesktop gtk-recordMyDesktop command.

The utility saves the recorded video as a .ogv file, which is fine if
you want to share it with other Linux users. But if you want to share
the screencast with the world by uploading it to one of many video
services such as YouTube or Vimeo, you have to convert the .ogv file
into one of the formats supported by these services. To do this, you
need to install two missing pieces first: the mencoder command-line
video conversion tool and Windows codecs. Neither Debian nor Ubuntu
have these packages in their default repositories, so you have to add a
repository containing them. On Sidux (which is based on Debian Sid),
you have to add the following repository using either the terminal or
Synaptic:

deb http://debian-multimedia.org/ sid main</pre>
<p>
On Ubuntu, you have to add the Medibuntu repository, and the <a href="https://help.ubuntu.com/community/Medibuntu" target="_self">Ubuntu Documentation Wiki</a>
explains how to do this. Run then the following command to reload the
repository information and install the mencoder and w32codecs packages:
</p>
<pre>apt-get update<br />apt-get install mencoder w32codecs</pre>
<p>
Now you can convert the .ogv screencast into the .avi file using the command below (replace <i>input.ogv</i> and <i>output.avi</i> with the source and target files):
</p>
<pre>mencoder -idx input.ogv -ovc lavc -oac mp3lame -o output.avi

That's all there is to it.

How to "Install Linux Applications from Source"

A nice short overview

Compiling Source Files: Theory and Practice

This is a good overview and gives a detailed "How To".

Here is part of the file.

....So where does all this compiling and linking take place? Most Linux systems have a /usr/local subdirectory.
The "local" refers to things that are specific to the local machine. In
other words, if a particular program isn't installed on all Linux
systems by default, then it represents something that is additional to
that particlar local machine. So most third-party programs and
utilities should be installed under this /usr/local subdirectory.



There are quite a few subdirectories under the /usr/local subdirectory. Two of them are /usr/local/src (for source code files) and /usr/local/bin (for binaries). The make utility will usually put any newly-compiled binaries in the /usr/local/bin directory.



With Linux, you typically issue four commands to compile, link, and install a program:

./configure  (may not have this)

make

make install

make clean

configure is
usually an extremely long and hideously complex shell script that the
program's author (hopefully) generated to make your compiling
experience easier. It basically checks out your system to see what you
have and where it is and to make sure it has everything it needs. I
have also seen this same type of script given the name of the program
or driver with a .sh extension (example
'myprogram.sh' instead of 'configure'). However, such scripts are no
guarantee of a successful compile. Such a script may also create a
thing called a "makefile" that is used by the make utility in the next step.



The make utility is what does the actual compiling and linking. If it's going to bomb, this is where it will bomb.



make install puts the compiled binary file in the proper (/usr/local/bin ) subdirectory.



make clean cleans up temporary files that were generated by the compiling and linking processes.



Now that you know what you'll be doing, and how to do, lets compile a
program. (Even though compiling is only one step in the process, the
term "compile" is often used to refer to the entire process of
compiling, linking, and installing.)
...


I liked them telling one to go to the diretory you want the file to be in BEFORE you do the download/extraction.

Vista Follow Up

My experience with Vista has had some setbacks. My video card locks up when I have a Belkin WiFi card installed

My HP 6980 printer with duplex printing will not print duplex automatically even though the setup indicates it is in duplex auto mode.

Impressions of Vista

I came by a version of Vista (premium) and loaded it on my 2.6GHz P4 w/1GB and 300GB drive. So far it works ok. I can't see the advantage over Windows XP though and the learning curve is just as steep as moving to Ubuntu.

I have not LOADED the new version of Ubuntu. I think I will put it on a separate HD.

I also set the display resolution after using Envy with the preferences pull down menu. I am not 100% sure that the resolution sticks after I do a shutdown but I can always reset using the nvidia utility.
