		<description><![CDATA[I&#8217;ve been having some problems with nasty black somewhat conductive sooty stuff getting onto my PCBs. I decided the quickest solution was conformal coating to protect the PCB. But I&#8217;ve never done that before and don&#8217;t know how. At first I thought of painting on epoxy with a paintbrush. But I was worried that once [...]]]></description>

		<description><![CDATA[The general problem with numeric date formats is this &#8211; what does &#8220;04.07&#8243; mean? Is it July 4th or April 7th? Or April 2007? Maybe July 2004? The answer is it&#8217;s ambiguous unless you have some other clues.  In general the separator is the clue; a dot (.) means it&#8217;s in Euro order (Day;Month;Year).  A [...]]]></description>

		<description><![CDATA[&#8230;indeed the best thing about patents is that they eventually expire. (And I say this as an inventor with multiple issued patents.) See, for instance, http://news.cnet.com/8301-10784_3-57374941-87/litigation-lunacy-silicon-valleys-lost-its-collective-mind/?part=rss&#38;subj=news&#38;tag=2547-1_3-0-20. And in general: http://www.techdirt.com/. Having said that, I guess I have to also say that I&#8217;m not against patents in principle, only in practice. I usually try to stay [...]]]></description>

		<description><![CDATA[Back in September 2011 I wrote about the rocket telemetry system I built using the Microchip MRF24J40MB radio module. As I mentioned back then, I ended up re-writing Microchip&#8217;s &#8220;MiWi P2P&#8221; stack to vastly simplify it for my application. A few people have asked for a copy of my simplified driver code, and today I&#8217;m [...]]]></description>

What mechanism could have created the hole? I took one look and said &#8220;cosmic ray hit&#8221;. But I was joking. The pot is [...]]]></description>
