-<p>There are two software projects that have had huge influence on the
-quality of free software, and I wanted to mention both in case someone
-do not yet know them.</p>
-
-<p>The first one is <a href="http://valgrind.org/">valgrind</a>, a
-tool to detect and expose errors in the memory handling of programs.
-It is easy to use, all one need to do is to run 'valgrind program',
-and it will report any problems on stdout. It is even better if the
-program include debug information. With debug information, it is able
-to report the source file name and line number where the problem
-occurs. It can report things like 'reading past memory block in file
-X line N, the memory block was allocated in file Y, line M', and
-'using uninitialised value in control logic'. This tool has made it
-trivial to investigate reproducible crash bugs in programs, and have
-reduced the number of this kind of bugs in free software a lot.
-
-<p>The second one is
-<a href="http://en.wikipedia.org/wiki/Coverity">Coverity</a> which is
-a source code checker. It is able to process the source of a program
-and find problems in the logic without running the program. It
-started out as the Stanford Checker and became well known when it was
-used to find bugs in the Linux kernel. It is now a commercial tool
-and the company behind it is running
-<a href="http://www.scan.coverity.com/">a community service</a> for the
-free software community, where a lot of free software projects get
-their source checked for free. Several thousand defects have been
-found and fixed so far. It can find errors like 'lock L taken in file
-X line N is never released if exiting in line M', or 'the code in file
-Y lines O to P can never be executed'. The projects included in the
-community service project have managed to get rid of a lot of
-reliability problems thanks to Coverity.</p>
-
-<p>I believe tools like this, that are able to automatically find
-errors in the source, are vital to improve the quality of software and
-make sure we can get rid of the crashing and failing software we are
-surrounded by today.</p>

+ <description><p>En standard er noe man samler seg rundt, ut fra ideen om at en får
+fordeler når mange står sammen. Jo flere som står sammen, jo
+bedre. Når en vet dette, blir det litt merkelig å lese noen av
+uttalelsene som er kommet inn til
+<a href="http://www.regjeringen.no/nb/dep/fad/dok/horinger/horingsdokumenter/2009/horing---referansekatalog-versjon-2/horingsuttalelser.html?id=549423">høringen
+om versjon 2 av statens referansekatalog over standarder</a>. Blant
+annet Abelia, NHO og Microsoft tror det er lurt med flere standarder
+innenfor samme område. Det blir som å si at det er fint om Norge
+standardiserte både på A4- og Letter-størrelser på arkene, ulik
+sporvidde på jernbaneskinnene, meter og fot som lengemål, eller
+høyre- og venstrekjøring - slik at en kan konkurrere på hvilken
+standard som er best. De fleste forstår heldigvis at dette ikke
+bidrar positivt.</p>
