         APRS Balloon Tracking Wanted - Raleigh Area - Feb 27

==== Please reply to:  Robert Krasowski <rkrasowski at yahoo. com> ====

Can you help with some APRS tracking, especially mobile?  Here's the
request I received from Robert Krasowski KB2PNM:

============ =
I am planning to launch balloon that hopefully will go up to 100,000
ft. Everything is completed, tested and I just waiting for time to
launch (27 Th of February).

I am in Asheboro. I plan to launch balloon from a location west from
my QTH. That will put landing zone close to Raleigh. Distance that my
balloon will travel as per latest jet stream speed and position give
traveling distance of balloon close to 200 miles with flight time 3h.
In order for me to catch up with the balloon I will have to drive
fast...

I am looking for somebody who can receive APRS from the car
(preferably) close to Raleigh. Balloon has GPS on board and APRS
transmitter, however, transmitting frequency will be 144.430MHz rather
than 144.390MHz. The reason for that is that I do not want to block
entire APRS network transmitting position of the balloon every 30 sec.

Check my Internet site www.anchorsat. com/balloon. html
Thanks in advance

I found this on KB6NU's blog (http://kb6nu.com/shackbox/) and it looks
like it might be an interesting Ubuntu derivative to check out.

I checked out the Web site, and am unable to evaluate exactly what the DVD
contains. I am not likely to download it, as 2 gigabytes makes for one huge
download. I always take the easy way out and get my DVDs from osdisc.com.
Alas, Shackbox is only available as a download from their site. A quick
Google check showed that a few glitches need to be ironed out. Live/CDs, or
LiveDVDs, can be memory killers.

I would like to compare the software list on Shackbox against what is
available from Ubuntu's repository. The Windows software is an interesting
addition. If they are running under Wine, you would definitely need a bit of
memory and a faster processor. Emulation does not exactly improve
performance.

I sure hope their packaging of Shackbox is better then there Web site.

Wine is not an emulator (in fact, I think it even stands for that
W-I-N-E).  It is a loader and a set of shared libraries that implement
the Win32 API using Linux calls.  That is, when someone calls
Win32OpenFileSomething(), it links to a function that actually opens the
files using Linux calls.  Some of these are low-level calls directly
from glibc, while others are nice window-ish dialog boxes written in
X-window primitives.  A good example of this is the "File / Open" dialog
box that you see in almost every Windows app.  WINE provides a "File /
Open" dialog box that happens to know how to navigate your home
directory, follow symlinks, and other Linux-ish things.

So... WINE will not be as slow as a CPU emulator, such as Qemu, which is
probably what you were thinking of.

You are correct in that WINE is not a true emulator as Qmenu. At some point,
all cross platform software faces the issue of differences between system
calls and their behavior. Just as the kernel uses the virtual file system to
create a common interface between applications and the wide variety of file
systems, so must cross-platform software provide a virtual interface that
hides the difference between kernel system calls. From user-space, system
calls are the only mechanism available to an application to communicate with
kernel space. Even extract kernel data from /proc (procfs file system)
involves a small set of system calls. One can stretch vfs a long ways. Now,
I have to find out how WINE works. It is a bad habit of mine - I am always
trying to figure out how things work. I am the under-the-hood guy.
