Landing on runway nine in Key West is a beautiful thing. Despite knowing that the duration of your stay will be less than an hour, an hour that will be truncated by an eager ground crew pushing for an early departure, you feel relaxed, relieved, even flush with content to be on the ground in Key West. Anticipating the warmth outside you laugh inside, for you left the cold air of the upper states mere hours ago. Revel in the jet age friend, revel.
</p>

<p><p>
Your eyes glide across the palm trees, hands fumble across the flaps, the lights, and miscellaneous switches, you mumble something to the tower, you&#8217;ve already checked out. There she is, a majestic beauty, the muse of your daydreams. What was it like? What a rugged, classy looking bird. A reflection of slower times.<img src="/files/CU-T1294.JPG" border="10" alt="Antonov An-24RV" hspace="20" vspace="20" width="500" height="153" align="absmiddle" />
</p></p>

<p>
The service of this Cubana Antonov An-24RV came to an end on March 31, 2003 flying unscheduled from Nueva Gerona to Key West with a fuel stop in Havana.  A man armed with two grenades forced this plane to Key West. At an airport ripe with business and regional jets the Antonov looks more natural in front of the Art Deco exterior of the Conch Republic Airport.
</p>

<p><span id="more-36"></span></p>

<p>
The An-24 was a product of the 1960s and was built through the late 1970s but its sturdiness has that older feel, maybe it&#8217;s the Russian design. I can&#8217;t help but wonder what it was like to fly this airplane. What was it like to ride in? I can picture myself with a straw hat and a wool suit. Cooling off with some Havana Club Rum on ice inflight. Oh, that ice had to be precious in Cuba during the summer. Now I think maybe a linen suit or seersucker perhaps. Yes, something cooler.
</p>

<p><p>
This plane has been here over four years but she showed her age before she arrived with balding tires and faded paint. Now she shows rust.  As the rear cabin door cracks open the smell of mildew billows out with the humid warm air. The Antonov is becoming a victim of the sub-tropical climate.
</p>
<p>
I wasn&#8217;t ready for the velvety blue seats as I am accustom to the grey tone interiors of today&#8217;s airline fleet. No over head bins. Just a rack for my hat, my coat, and the leather brief case that I carry &#8211; containing only a pen and my flask. The case was a gift but it looks good with my suit. Daydreaming again. <img src="/files/An24Cabin.JPG" border="10" alt="An-24RV cabin" hspace="20" vspace="20" width="500" height="334" align="right" />
</p>
<p>
Riding is fine but I am a Pilot.  I make my way through the cabin and the forward cargo compartment to the cockpit. The harsh Florida Sun shines through holes in the decomposing shades that cover the windscreens. So many gauges. Switches. All function, no form. The systems are all labeled in the cyrillic letters of the Motherland. Emergency placards stenciled on in Spanish. <img src="/files/An24Cockpit.JPG" border="10" alt="An-24RV cockpit" hspace="20" vspace="20" width="500" height="334" align="left" />
</p>
<p>
The well worn pilots chairs are covered in a green toned tropical leaf print fabric. A station for an engineer or navigator behind the co-pilot with a tiny desk and a large round window and no fixed chair. An observer seat behind the captain. Full oxygen masks and goggles at each station.<img src="/files/An24EngPanel.JPG" border="10" alt="An-24RV Engineer Panel" hspace="20" vspace="20" width="251" height="375" align="right" />
</p>
<p>
The cockpit is intimidating. A pilot IS the computer in this plane, recieving, interpreting, and responding to the data. Look at all of these gauges. Switches! So many switches.  I want to fly it. I want to hear what the engines sound like. I want to come through the mountain pass and land on the steaming, rain soaked, runway in Cuba after a summer thunder storm passes. Can you imagine that?
</p>
<p>
Rampers wait beside our plane, they are antsy, they want the ontime departure, the early departure. The passengers have been boarded and the bags loaded while we ogled the Antonov &#8211; dreaming of slower times.

			<content:encoded><![CDATA[<p>Making the commitment to partition your precious laptop&#8217;s hard disk in order to install the Ubuntu Linux operating system is not always an easy thing to do.  This tutorial will describe in detail how to install Kubuntu on a removable 4GB USB flash drive, and configure the bootloader to boot Linux whenever the drive is connected.</p>

<div style="text-align:center;">
  <img src="/files/usbuntu.jpg" alt="USBuntu" />
</div>

<p>Lately I have been fooling around with Kubuntu on a desktop computer and I really wanted to use it on my laptop.  However, I was
hesitant to partition my hard drive because I have a lot of documents and pictures and software that I would hate to lose in the event something went wrong.  Additionally, I don&#8217;t have a tremendous amount of free space on my hard drive to devote to another operating system.  So I decided to try to install Kubuntu on a USB flash drive.</p>

<p><span id="more-25"></span></p>

<p>I found some posts in the Ubuntu forums that helped
figure out how to make installing Kubuntu to a USB drive possible; <a href="http://ubuntuforums.org/showthread.php?t=80811">this one was the
most helpful</a>.
It&#8217;s very thorough and the thread covers many issues that arise
with different hardware configurations. My experience was slightly
different than what the post describes so I will detail the steps I
took to install Kubuntu on a USB drive.</p>

<p>First off, my laptop is a Dell E1405, and the USB drive I used is the <a href="http://www.sandisk.com/Products/Item(1925)-SDCZ6-4096-A10-SanDisk_Cruzer_Micro_4GB_Black.aspx">SanDisk Cruzer 4Gb</a>
which periodically goes on sale for a little less than 40 bucks. I
think the write speed is slow but it has a nice orange light which will
dazzle you while you wait. The 2 Gb version will work, but I had to do
a lot of software removal to make it happen (I will be testing Xubuntu
on the 2Gb drive in the near future). I highly recommend just using 4Gb
or more.</p>

<p>Secondly, I&#8217;m still relatively new to Linux. This certainly isn&#8217;t the be-all-end-all tutorial, and I can&#8217;t guarantee that these steps will work on hardware other than Dell&#8217;s E1405 with an Intel Pro
wireless card, or the San Disk Cruzer USB drive.</p>

<h4>Preparing the USB Drive</h4>

<p>Before you do any thing else. Uninstall <strong>ALL</strong> of the software that
comes pre-installed on the USB drive. When you plug in the USB drive
SanDisk U3 software automatically loads. Use the icon in the system
tray to find the uninstall feature. It is a bit hidden and I don&#8217;t
remember exactly what tab it is under. It might require a right click.
After I uninstalled U3 I also re-formatted the drive, not sure if it is
necessary.</p>

<h4>Getting Kubuntu</h4>

<p>Head over to the <a href="http://www.kubuntu.org/download.php#latest">Kubuntu download page</a>  and download the Feisty Fawn 7.04 Live CD and the Alternate install CD. There is a <a href="https://help.ubuntu.com/community/BurningIsoHowto">Ubuntu Documentation</a> page that will tell you how to burn the files on to a CD to make a bootable .ISO image using the <a href="http://infrarecorder.sourceforge.net/">Infra Recorder</a>
software. (The Live CD is not part of the actual install process but it
is helpful in determining what you computer calls the devices that we
will be installing Kubuntu on. It is also nice to have around for
future use.)
After your CDs are burned make sure to take them out of the CD drive.
You should then restart your computer and enter the BIOS Setup page as
your computer restarts. Verify that your computer will boot in the
order of CD, USB, then Hard Drive.</p>

<h4>Finding Your USB (Device Node) Name</h4>

<p>Insert the Live CD and exit the BIOS. The live CD takes a little while
to load. Once you are on the Kubuntu Desktop, plug in your USB device.
You can find the device node by putting the mouse pointer over the
device icon or by using the system menu icon, the second icon from the
left on the bottom panel menu, and select &#8220;Storage Media.&#8221; In the Storage
Media expanded menu you can see the internal drive and the USB drive.
Write down the name. On my Dell E1405 the USB drive is listed as
<code>/dev/sdb</code> and the hard drive as <code>/dev/sda</code> with the various drive
partitions numbered like <code>/dev/sda2</code>. So I know that I will be doing all of
my installing to sdb and NOT my internal drive sda. Other computers use
device nodes like hda or hdb.</p>

<h4>Installation</h4>

<p>When you are ready to install, log out and get the Live CD out of the
tray. When you restart the computer, enter the BIOS and insert the
Alternate Install CD. Exit the BIOS. The Install Menu screen be present
now.</p>

<p>The “Install in Text Mode” is the first option. Select it for a normal
install. I&#8217;ll just walk through my notes here and what I remember the
installer asking and the choices I made. IMPORTANT: Be careful not to
install GRUB Loader to the Master Boot Record!  This step comes after the
timezone and username selections.</p>

<ul>
<li><p><strong>Choose your Language and Country.</strong></p></li>
<li><p><strong>Detect keyboard layout.</strong> For US keyboards select “No” then select Origin&#8211;&gt;U.S. English and Layout &#8211;&gt;U.S. English.</p></li>
<li><p><strong>Network configuration.</strong>  If you are not connected to a network you
can hit “Cancel” or if a network is not present select “Configure
later”</p></li>
<li><p><strong>Hostname.</strong> Choose a name for your computer.</p></li>
<li><p><strong>Partition Disks.</strong> Select “Guided &#8211; use entire disk.” Select your USB drive. It should show a description of your USB drive and include the device node that you found earlier (e.g. <code>sdb</code>). <em>Do NOT</em> choose your internal drive!</p></li>
<li><p><strong>Finish Partitions and write changes.</strong> Write to disk&#8211;&gt; yes</p></li>
<li><p><strong>Choose Timezone</strong></p></li>
<li><p><strong>Choose Username, Username Account, and Password.</strong></p></li>
</ul>

<div class="help">
<strong>READ THIS:</strong>  The GRUB Boot Loader wants to install next. DO NOT install to MASTER BOOT RECORD. Select NO. If you do not select “NO” GRUB will install to
your hard drive.
</div>

<ul>
<li><strong>Write in your USB device node.</strong>  Once again, mine was: <code>/dev/sdb</code>.  (The text says you could use (<code>sdb</code>) instead of <code>/dev/sdb</code> but the installer didn&#8217;t like when I tried it that way.)</li>
</ul>

<h4>Configuring the GRUB Bootloader</h4>

<p>Your installation should now be complete.  Be sure to eject the disk before you shut down your computer.
When you start up again you will have to do some editing in the GRUB
menu. GRUB is looking at the wrong drive to boot so we need to tell it
to look at the correct drive. This editing is temporary for this start
up only.</p>

<p>When the GRUB menu appears, use an arrow key to move the line selection
so that the automatic start up timer stops. If you missed the timer the
system will try to boot and will give you some sort of Error 17 message
about invalid partitions or something. The ESC key should bring you
back to the GRUB menu.</p>

<p>Select the first line in the grub menu “Ubuntu Kernel&#8230;.”
Type &#8216;e&#8217; to edit.</p>

<p>In the next menu  select the first line <code>Root  (hd1,0)</code>.
Type &#8216;e&#8217; to edit.</p>

<p>Use the arrows and back space to edit the line
<code>grub edit&gt; root (hd1,0)</code> to read  <code>grub edit&gt; root (hd0,0)</code></p>

<p>Hit the ENTER key to make the change and you will be directed back to the previous menu.</p>

<p>Now hit “b” to boot Kubuntu!</p>

<p>You can make this boot change permanent by entering the terminal
from Kmenu-&gt; System-&gt; Konsole(Terminal Program)</p>

<p><strong>Editing GRUB menu.lst</strong></p>

<p>On my first attempt at installing Kubuntu on a USB I edited the <code>menu.lst</code> to make the
permanent change. It works fine until you do a kernel update. In my latest attempt I have not permanently edited the file and I have not done a kernel update.</p>

<p>To edit type:</p>

<pre><code>sudo nano /boot/grub/menu.lst
</code></pre>

<p>Use the arrow keys to navigate down until you see this just past the line that reads</p>

<pre><code>## ## End Default Options ##

title           Ubuntu, kernel 2.6.20-15-generic
root            (hd1,0)

kernel/boot/vmlinuz-2.6.20-15-genericroot=UUID=75660762-f5cf-4b5d-97$
initrd          /boot/initrd.img-2.6.20-15-generic
quiet

savedefault
</code></pre>

<p>change  <code>root   (hd1,0)</code> to <code>(hd0,0)</code>
make this change for the recovery mode “title Ubuntu, kernel
2.6.20-15-generic (recovery mode)” and memtest “title Ubuntu,
memtest86+” too. Both are the right underneath the first group that you
just edited.</p>

<p>The tutorial mentions making changes to
<code>## default grub root device</code></p>

<p><code>## e.g. groot=(hd0,0)</code></p>

<p><code># groot=(hd1,0)</code></p>

<p>so that <code># groot=(hd1,0)</code> also is changed to <code>(hd1,0)</code>.  One user posted
a comment about the kernel update reading the line with only one <code>#</code> to
determine the location of the Boot Loader. As I mentioned previously, I
have not made these permanent edits yet and do not know if they work. I
bricked my USB Kubuntu after a kernel update and had to start over
again. I&#8217;ll try making these edits in the near future and post my
findings when I can. In the meantime I edit the GRUB every time I
start up &#8230; I think it&#8217;s kinda fun.</p>

<h4>Hardware Issues</h4>

<p>If your hardware differs from mine or something is not working,
check out the tutorial I mentioned above. This tutorial makes many
edits in the terminal which I found my with hardware configuration or
Kubuntu version to be unnecessary.</p>

<p>The only major glitch I had with hardware was my screen resolution. The
<code>intel i810</code> driver didn&#8217;t want to give me the native 1280&#215;800
resolution. There was a quick fix found <a href="https://help.ubuntu.com/community/FixVideoResolutionHowto">here</a>.
Once again there are several steps listed, but for some reason all I had to do was go to the Terminal and type:</p>

<pre><code>sudo apt-get install 915resolution
</code></pre>

<p>After logging out and back in, my resolution worked. Again if you have
troubles or different hardware that link is a good place to start and
you may need to follow the additional steps to get your screen
resolution working.</p>

<p>The other nice thing is that you can mount your internal hard drive so
that you can read (and possibly write) files. This is great when you
need to access something from your hard drive and you don&#8217;t want to
shutdown your computer and restart without the USB.</p>

<p>That&#8217;s all for now. Hope this helps.</p>
