		<description><![CDATA[Minix seems to be inspiring more operating systems nowadays. Microsoft Research is investing on a micro-kernel (they call it multi-kernel, as there are slight differences) called Barrelfish. Despite being Microsoft, it&#8217;s BSD licensed. The mailing list looks pretty empty, the last snapshot is half a year ago and I couldn&#8217;t find an svn repository, but [...]]]></description>

What I saw was a bunch of experts discussing the plethora of standards that could be applied (very important) but few people seemed too interested in the privacy [...]]]></description>

		<description><![CDATA[I&#8217;ve been working with workflow pipelines, directly and indirectly, for quite a while now and one thing that is clearly visible is that, the way most people do it, it doesn&#8217;t scale. Workflows (aka. Pipelines) If you have a sequence of, say, 10 processes in a row (or graph) of dependencies and you need to [...]]]></description>

		<description><![CDATA[Mike Stonebreaker (Ingres/Postgres) seems to be confused as well&#8230; First he said Google&#8217;s Map/Reduce was &#8220;Missing most of the features that are routinely included in current DBMS&#8221;, but earlier he said to ditch RDBMS anyway because &#8220;modern use of computers renders many features of mainstream DBMS obsolete&#8221;.

		<description><![CDATA[Recently I&#8217;ve posted this entry about how NFS cache was playing tricks on me and how sleep 1 kinda solved the issue. The problem got worse, of course. I&#8217;ve raised to 5 seconds and in some cases it was still not enough, than I&#8217;ve learnt from the admins that the NFS cache timeout was 60 [...]]]></description>

		<description><![CDATA[I use LSF at work, a very good job scheduler. To parallelize my jobs I use Makefiles (with -j option) and inside every rule I run the command with the job scheduler. Some commands call other Makefiles, cascading even more the spawn of jobs. Sometimes I achieve 200+ jobs in parallel. Our shared disk BlueArc [...]]]></description>

Seems pretty nice but some things worries me a bit &#8230; Of course a highly interconnected backpane and some smart shortest-path routing algorithms (probably not as good as Feynman&#8217;s) is much faster (and reliable?) than gigabit ethernet (myrinet also?).

		<description><![CDATA[When updating the nodes I have to download several times (N for N nodes) the same packages, so a good idea is to have a proxy that would do it for me once and all nodes get from the local copy. For that we have the good old squid. On the Master node: $ sudo [...]]]></description>

		<description><![CDATA[To stop copying everything all the time I needed a shared disk. Parallel Virtual File system was my parallel FS of choice but also I needed a quick and not so fast and reliable filesystem for tests. For that, I chose NFS. Later I can install PVFS if I need to.
