			<content:encoded><![CDATA[<p>After watching Ava use Thunderbird on <a href="http://www.redecho.org/2012/01/27/1078/">her new netbook</a>, I realised there was no reason I had to keep using the web interface when I wanted to read mail on mine. I have an ancient <a href="en.wikipedia.org/wiki/Post_Office_Protocol">POP3-era</a> habit of only setting up an email client on one machine at a time, but thanks to <a href="http://en.wikipedia.org/wiki/Internet_Message_Access_Protocol">the wonder that is IMAP</a> there&#8217;s no reason to keep that up. Messages will show up in as many places as I care to read them and all devices stay synchronised.</p>
<p>I&#8217;m not so happy with the default Thunderbird layout on this Eee pc screen, though. The fonts are clearly designed for a much larger screen, and they take up much more space than is necessary. There&#8217;s no preference setting that allows you to change the font size, but I found a <a href="http://www-archive.mozilla.org/unix/customizing.html#usercss">curiously obscure CSS hack that makes it work</a>. If you create a file named <code>userChrome.css</code> inside your Thunderbird profile directory, you can override all the factory style settings, whether they have options in the preferences box or not. Point size 9 works really well on this 1024&#215;600 screen. </p>

			<content:encoded><![CDATA[<p><a href="http://www.enertrac.net/">EnerTrac</a> has a <a href="http://www.enertrac.net/product.php">motorcycle hub motor</a> for sale which looks like just about the easiest way to get an electric bike rolling. (I mentioned this <a href="http://www.redecho.org/2009/04/20/605/">a couple of years back, when it was still a prototype</a>.) It&#8217;s hard to make a straight-up comparison, but it appears to be a fair bit more expensive than an equivalent non-hub motor. I guess that makes sense as it likely involves more custom engineering &#8211; they have to lace a wheel up around it, after all.</p>
<p>Looks like most people are running these motors at around 100 volts, and getting speeds up to about 75 mph. Not bad! I&#8217;ve been thinking about setting a 72 volt system, so my top speed would be more like 55 mph. There&#8217;s nothing &#8220;wow&#8221; about that but it would be plenty for a city commuter.</p>
<p>While I could probably get a more powerful non-hub motor, I&#8217;m tempted to go this route because it would make the project simpler &#8211; no more custom motor mount to design and fabricate, and no more chain and sprockets to spec and install (or maintain). I don&#8217;t really want to engineer the drivetrain anyway; I&#8217;d rather focus on the electrical components.</p>

It doesn&#8217;t appear to have the ability to store multiple loops at once, but I never really use that feature during live sets anyway. The console form factor is really nice and would allow me to set up a much thinner, lighter performance rig, since it wouldn&#8217;t have to accomodate rackmounted gear.</p>

There are other frames at similar prices, but the CB750 has a nice square engine compartment that would work well for holding batteries. I&#8217;m seriously tempted to buy it and start building an electric motorcycle around it, like, <i>now</i>. I imagine it&#8217;d take 3-6 months or so to get it running, but that seems well worth it if I end up with a bike I can ride to work every day.</p>

			<content:encoded><![CDATA[<p>The <a href="http://brutusmotorcycle.com/">Brutus electric motorcycle</a> is a stylish beast of a machine. It has a manual transmission, an odd choice for an electric bike, and they claim a 100 mile range. They&#8217;re pricing it up in Harley territory, though; it&#8217;s estimated to cost about $35,000. </p>
<p>The <a href="http://www.litogreenmotion.com/">Lito Sora</a> has a similar shape but more of a high-tech style; they use a CVT and claim 300km range. The design is a little too widgety for my taste, overall, but I really like that taillight. They have not shipped yet and are not advertising a price.</p>
<p>Zero comes at it from a more off-road background with their <a href="http://www.zeromotorcycles.com/street/">Zero S</a>, which is clunkier in style but actually exists here and now; for $14k you get a bike with ~100 mile range and an 88 mph top speed.</p>
<p>Brammo seems to be stuck in development hell; their web site has been offering pre-orders for the <a href="http://www.brammo.com/store/brammo-enertia-plus/">Enertia Plus</a> and <a href="http://www.brammo.com/store/brammo-empulse/">Empulse</a> models for over a year, but they are out of stock of everything but the older Enertia, in green. If the Empulse ever ships it will be a nice, fast, 100 mph sportbike costing about $14k.</p>

			<content:encoded><![CDATA[<p>I&#8217;ve been doing a lot of work on <a href="http://www.radian-lang.org/">Radian</a> lately. Today&#8217;s project was adding support for rational numbers, which means it can deal with fractions now and not just whole numbers.  I expect I will put out another binary release this weekend.</p>
<p>The dress for Jeanine is coming along slowly; I&#8217;ve been pecking at it in small bursts. I finished up the lining today and sewed it on to the body material along the neck line. I made a mistake I&#8217;ll have to go back and correct but it&#8217;s a simple thing. I doubt there&#8217;s more than an evening&#8217;s work left to finish the project.</p>
<p>Today I went over to West Seattle and picked up <a href="http://www.airlighttimespace.org/2012/01/new-industrial-serger/">an industrial serger for ALTSpace</a>. It&#8217;s made by some no-name Chinese factory, but it was priced to <i>move</i> &#8211; some guy who was the non-sewing half of a small fashion business ended up with all the gear, and after it took up space in his garage for a year he just wanted it gone. I tried it out and it works well; it&#8217;s very, very fast.</p>

			<content:encoded><![CDATA[<p>Ava just got an Acer Aspire One, the 522 model. We installed Ubuntu 11.10, which is very pretty and which has an install procedure about as easy as it could possibly be. The machine worked fine for about a day, then started locking up, seemingly at random. Oh no!</p>
<p>Ava eventually noticed that the lock-up happened when the machine connected to the network. After poking at it for several hours and going through a handful of reinstalls, I found this page which <a href="http://bernaerts.dyndns.org/linux/202-ubuntu-acer-ao722">explains the problem and offers a simple fix</a>:</p>
<blockquote><p>In fact, every time you try to connect to a wireless network, your netbook may freeze, the only option being a hard reset !</p>
<p>It seems that this bug comes from a conflict between the ethernet and the wireless adapter.</p>
<p>But the good news is that there is a very simple tip to avoid this bug : you need to setup a specific boot order, where the network boot is used first. With this setup, the ethernet adapter will be configured in a way that there won&#8217;t be any conflict with the wifi adpater at the time of wireless network connexion.
</p></blockquote>
<p>Ah, what a relief. The fix works perfectly.</p>

<p>This is pretty far out in &#8220;well, duh&#8221; territory, but after a couple decades watching law enforcement agencies get everything they ask for in the name of various imaginary wars on various imaginary bogeymen, it&#8217;s awfully satisfying to see them take a rebuff for once. </p>
