		<title>A platform too many</title>
		<description><![CDATA[With the new iBooks and iTunes U app, I&#8217;m missing a piece of the puzzle. Just as truckloads of schools have given the kids MacBooks, Apple rolls out the new textbooks to iPads only. Are we supposed to switch over the schoolkids to iPads now, and lose the OSX apps they use? It would seem [...]]]></description>

		<title>Another creator pattern for clusters</title>
		<description><![CDATA[This is about Cocoa, and in particular about class clusters. The problem I wanted to solve was having a class cluster with easily extendable hierarchy without too much interdependency. In my case, I want to create a number of different UITableViewCell descendants, depending on the particular data element the cell should handle. If the data [...]]]></description>

		<title>Dr Dobbs circling the drain</title>
		<description><![CDATA[I&#8217;ve subscribed to Dr Dobbs journal off and on for decades, probably for ten to 15 years in total. Wherever I turn in this house, I encounter stacks of old issues of DDJ, even though I&#8217;ve thrown away quite a number. A couple of years ago I stopped subscribing, since the main focus of DDJ [...]]]></description>

		<title>Death of medical articles?</title>
		<description><![CDATA[Check out this article on &#8220;Improbable Research&#8221;. In short, it&#8217;s an application that can take raw data and write an article around it. Personally, I think it&#8217;s a good thing if the result is more objective and complete than most journalistic writing we see today. Can&#8217;t be less researched, at least. But it also goes [...]]]></description>

		<title>Netbooting on OSX SL Server</title>
		<description><![CDATA[Once I got tftp working on IPv4, I still couldn&#8217;t get the Macbook client to download the boot or image files. Wireshark showed that the client didn&#8217;t get any file when it sent &#8220;acknowledge data block 0&#8243;. Nothing. So I installed tftp-hpa from Macports, hoping that would solve my problem, which it didn&#8217;t. But a [...]]]></description>

		<title>OSX SL tftp doesn&#8217;t work?</title>
		<description><![CDATA[&#8230;then this may be the reason&#8230; took me hours to figure out. Had to get it going for a netboot project, and the netboot just kept circling around the boot image download without getting much anywhere. First, check out Bombich&#8217;s troubleshooting, which put me on the right track without actually giving me the solution, but [...]]]></description>

		<title>Don&#8217;t trust iTunes gift cards</title>
		<description><![CDATA[This is what happened to me. I gave a friend $300 to buy gift cards for iTunes, and he got me six $50 cards in the Woodlands Best Buy store in Texas. This was in november 2009. Me and a relative redeemed three of these cards during the following months, but I only got around [...]]]></description>

		<title>The first thing you should do on a new Mac</title>
		<description><![CDATA[The very first thing you should always do on your new Mac is to make sure you run as non-admin. This protects you against most malware out on the net, since it makes it very difficult to install anything without you knowing about it. It doesn&#8217;t exclude it entirely, but it makes a major difference. [...]]]></description>

		<title>Macport and mono</title>
		<description><![CDATA[Just a heads-up: Macport quit working on my machine. Link errors, missing architecture in sqllite3 dynamic libs or something. After much agonizing, I began to suspect mono, especially since the sqllite3 library port wanted to link against was in the mono path. There&#8217;s a shell script in mono called uninstallMono.sh that does a fine job [...]]]></description>

		<title>Lecture</title>
		<description><![CDATA[I was invited to give a lecture to the International Masters Programme in Health Informatics at Karolinska Institute, and we recorded a video of the entire lecture, in total around 3.5 hours. The last part is about iotaMed, our open source project for a &#8220;new and improved&#8221; electronic health care record, which is knowledge support, [...]]]></description>
