			<content:encoded><![CDATA[	<p><a href="https://www.levelostar.fr/">Le vélo Star</a> is a public bicycle rental service provided by Keolis for the city of Rennes and it opened last year. At first, data were not provided officially, although one could look at the source of their google maps use to see that a list of station was available as a <span class="caps">XML</span> file and detailed informations were in <span class="caps">HTML</span> fragments. However, Rennes Métropole has decided to open up its data and the first step in this direction was done early this week by Keolis Rennes providing an <a href="http://data.keolis-rennes.com"><span class="caps">API</span> for Le Vélo Star</a>. </p>

	<p>So, I wanted to do something with it. Building a google maps stye application would have been easy but I tried for something different. I first started by building a script that would collect and store the data (number of bikes and slots available for each station) using <a href="http://oss.oetiker.ch/rrdtool/"><span class="caps">RRD</span></a>. Graphs are nice, but it wasn&#8217;t helping much seeing the whole picture. So instead, using a background image generated from <a href="http://www.openstreetmap.org">OpenStreetMap</a> I built a <a href="http://www.youtube.com/watch?v=H5ytqWZgSa0">time-lapse animation of the stations&#8217; usage</a>. </p>

	<p>All the code I wrote is available on my <a href="http://github.com/stanguy/velostar">Github repository</a>, except for the animation bit, were I currently used iMovie.</p>]]></content:encoded>

			<content:encoded><![CDATA[	<p>So, Apple showed the world its new world domination toy, the <a href="http://www.apple.com/ipad">iPad</a>. What do I think about it? First, the name is silly and boring. The device seems interesting with limited capabilities, but most probably due to physical and technical constraints. Sure, it can&#8217;t do multitasking and it is just an oversized iPhone, but one has to take into account that the thing is thin and that the battery is good even though the display and the faster processor would be more power-hungry than those on the iPhone/Touch.</p>

	<p>Would I buy one? Not yet. Although I&#8217;m a good target, I think that this is still a bit expensive (not even speaking of the cash cow represented by the various storage capacities, and what about the OS updates?) for what it can do and my pocket are not that deep. I would rather keep a laptop instead, at the time being, for home usage. Hopefully, in one or two years, it will get better feature-wise. Would it get more &#8220;open&#8221; to other apps? Not sure Apple would let go. </p>

	<p>However, I think this represents a kick in the nuts for the eReader market. Many of those compete on the features and in the end are expensive old-fashioned (b&#038;w) devices. If I had to choose between an Apple iPad and any 10&#8221; eReader, at the same price, I think the <span class="caps">LCD</span> screen would win this time. I don&#8217;t know if they could compete directly with the iPad. Build a cross-over device with ePaper and touch capabilities at the same time? Not likely to win. My guess is that they would better try to go against the touch/iphone, with simple/cheap 6&#8221; devices, where they can&#8217;t be reached by glossy and battery-hungry gadgets.</p>]]></content:encoded>

<span id="more-323"></span><br />
Sure, the usual culprit is most of time the flash plugin. Ok, that&#8217;s an external thing, that could be an excuse. But my guess is more on the thread management (which was already the subject of my previous post). Sometimes it would freeze loading a page when moving the mouse around. (I would bet on some kind of race condition between the cookies handling and the javascript interpreter).<br />
If somebody wanted to bad mouth apple, one could say that they send out buggy software, crashing, being slow as molasses (I&#8217;m looking at you, iTunes), but mostly on older operating system releases, to push people to the upgrade way.<br />
Bleh!</p>]]></content:encoded>

And since I was having some spare time recently and some good weather, I was also playing a bit with my <span class="caps">GPS</span>. So, one thing leading to another, and the rewrite starts to look good. But I still have quite a few features to add. And with some luck and  inspiratio, I may even be able to finish the original application.</p>
