    <content:encoded>&lt;p&gt;Nokia's &lt;a href="http://www.nseries.com/products/n800/index.html#l=products,n800"&gt;N800 internet tablet&lt;/a&gt; is an intriguing device. When I originally got one a few months back I tried to treat it purely as a consumer object, just using the installed apps and things available through the obvious point-and-click channels.&lt;/p&gt;&lt;p&gt;As a consequence it served mainly as a portable (and expensive) internet radio, streaming me the &lt;a href="http://news.bbc.co.uk/sport1/hi/cricket/tms/default.stm"&gt;cricket commentary&lt;/a&gt; from the BBC. And when I upgraded my wireless network I somehow managed to make it WPA2 only, knocking the N800 offline. An offline N800 is an almost thoroughly useless device, so it went into the drawer and I forgot about it.&lt;/p&gt;&lt;p&gt;Ultimately you can't leave something that expensive unused, so I dragged it out again, fiddled the wi-fi router into compliance, and decided not to deny my hacker nature this time. The N800 is Linux underneath, so who could resist?&lt;br /&gt;&lt;/p&gt;&lt;p&gt;The result is two-edged, really: I'm a lot happier with the device, but on the other hand must conclude that the N800 is still a bit far from being consumer-ready.&lt;/p&gt;&lt;h3&gt;Must-have software&lt;/h3&gt;&lt;p&gt;So, what things did I install this time around that made the device happier?&lt;/p&gt;&lt;p&gt;&lt;a href="http://www.claws-mail.org/maemo/"&gt;Claws Mail&lt;/a&gt; is a nice email client that works well with my IMAP accounts, which all use SSL and TLS, have lots of messages and a deep folder hierarchy. I don't really want to write much mail on the N800, but an easy reading interface is a bonus.&lt;/p&gt;&lt;p&gt;The &lt;a href="http://www.internettablettalk.com/forums/showthread.php?t=4580"&gt;FM radio&lt;/a&gt; is something I can't believe I missed before. I had no idea this was in there, but plug some headphones into the N800 and they act as the antenna for an FM receiver. Desperately cute and old-world, a bit like when laptops still used to have parallel printer ports.&lt;/p&gt;&lt;p&gt;I had previously ignored &lt;a href="http://downloads.maemo.org/product/maemo-mapper/"&gt;Maemo Mapper&lt;/a&gt;, thinking it was useless without a GPS, but it turns out to work very nicely as a dedicated client for Google Maps, as well as several other mapping sources.&amp;nbsp;&lt;/p&gt;&lt;h3&gt;Must-do geeky bits&lt;/h3&gt;&lt;p&gt;Try as I might to like the touch screen, the first thing I had to do with the device was find a way of not using the stylus to do sysadmin type tasks on it.&lt;/p&gt;&lt;p&gt;So, first stop is to get a &lt;a href="http://maemo.org/downloads/product/osso-xterm-advanced"&gt;terminal&lt;/a&gt; up, figure out &lt;a href="http://maemo.org/community/wiki/HowTo_EASILY_BecomeRoot"&gt;how to use the root account&lt;/a&gt;, install a &lt;a href="http://maemo.org/downloads/product/dropbear"&gt;SSH client and server&lt;/a&gt;, and get my pubkey onto the N800. Now I could shell into it and use a decent keyboard.&lt;/p&gt;&lt;p&gt;On my local network I hate maintaining DNS if I don't have to, so the next thing I wanted was Zeroconf support in the shape of &lt;em&gt;avahi&lt;/em&gt;. One of the quickest ways to get this going is to install the &lt;a href="http://openbossa.indt.org.br/canola/"&gt;Canola&lt;/a&gt; media application, which uses Zeroconf to find shared music.&lt;/p&gt;&lt;p&gt;With these basics in place, the N800 supports APT package repositories familiar to Debian and Ubuntu users, so the device becomes a lot less weird and much more manageable. I felt the same pleasant familiarity as I did with the &lt;a href="http://times.usefulinc.com/2007/05/31-nslu2"&gt;NSLU2&lt;/a&gt;.&amp;nbsp;&lt;/p&gt;&lt;h3&gt;Things to look forward to&lt;/h3&gt;&lt;p&gt;The N800's video camera is neat, but nobody I know uses Google Talk for conferencing. Fortunately it seems that Skype for the N800 is &lt;a href="http://mobilitysite.com/2007/06/skype-on-the-nokia-n800-coming-soon/"&gt;just around the corner&lt;/a&gt;. Initially, video support is unlikely, but I imagine that if Skype on the N800 proves popular, it won't be far off.&lt;/p&gt;&lt;p&gt;The N800 is something I don't mind having kicking around the kitchen or nursery, so staying in touch with my family while I'm travelling will become a lot more fun.&lt;br /&gt;&lt;/p&gt;&lt;p&gt;Also, I'd like to get NFS running on the N800, but that requires the installation of a new kernel, which I've not quite yet had the time to do. Once that's done, all my media, photos and storage will be handily available.&amp;nbsp;&lt;/p&gt;&lt;p&gt;&lt;a href="http://times.usefulinc.com/2007/07/02-n800-again#disqus_thread"&gt;Join the conversation about this post&lt;/a&gt;&lt;/p&gt;</content:encoded>

    <title>Orange 3G data card</title>

    <description>A few notes on my new Orange 3G data card.</description>

&lt;p&gt;Another quick and dirty review.&lt;/p&gt;
&lt;p&gt;Recent trips to places without wi-fi left me with a staggering GPRS bill, so it
made sense to investigate a proper mobile data solution.  None of the packages
available in the UK are particularly cheap, I should say, but a lot better than
what I was paying for GPRS overage.&lt;/p&gt;
&lt;p&gt;I settled on the &lt;a href="http://shop.orange.co.uk/shop/show/handset/3g_mobile_office_card/detail"&gt;Orange 3G data card&lt;/a&gt; based on a combination of Linux compatibility
and network coverage.&lt;/p&gt;
&lt;p&gt;Plugging the card into my Ubuntu laptop, it appeared as a serial modem.  &lt;a href="http://www.timberwolf.ukfsn.org/debian-orange-3g.html"&gt;A
page by Jules Kavanagh&lt;/a&gt;
has extensive details on configuring the card.  I used his PPP settings and
they worked fine.&lt;/p&gt;
&lt;p&gt;&lt;div style="float: right; border-left: 10px"&gt;&lt;img src="http://usefulinc.com/edd/blog/contents/2005/06/3gcard.jpg"
width="384" height="294" alt="Orange 3G Card" /&gt;&lt;br /&gt;&lt;em&gt;Orange 3G card 
and my Sony TR1-MP&lt;/em&gt;&lt;/div&gt;&lt;/p&gt;
&lt;p&gt;So, here's the quick lowdown for anybody else in the UK and interested in this
card:&lt;/p&gt;

&lt;ul&gt;
&lt;li&gt;Seems to migrate between GPRS and 3G well&lt;/li&gt;
&lt;li&gt;Requires first run to be in Windows, in order to process the activation SMS that Orange send you.  (There is almost certainly a Linux way around this, but I couldn't get &lt;i&gt;gsmsmsd&lt;/i&gt; to read the SMS from the card and got bored.)&lt;/li&gt;
&lt;li&gt;Download speeds at least 256kps (advertised max. is 384kpbs, but 256 seemed more typical for me.)&lt;/li&gt;
&lt;li&gt;Throughput good, but latency poor, as with GPRS&lt;/li&gt;
&lt;li&gt;Comes with a protective plastic case, contrary to what is said in &lt;a href="http://www.theregister.co.uk/2004/10/27/review_orange_3g_card/"&gt;the Register's review&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;I appear to have got a 1GB allowance free for three months&lt;/li&gt;

&lt;/ul&gt;
&lt;p&gt;Consider me happy.  It was a life saver when my DSL migration messed up
this week and left me without internets for two and a half days.&lt;/p&gt;
&lt;/div&gt;
