Wenn man diese Fehlermeldung ‘umgeht’ indem man die Bibliothek nur dynamisch baut, dann kompiliert alles fein; aber weil die Funktionen weiterhin fehlen, tritt der Fehler dann eben zur Laufzeit auf und man kann umsomehr Stunden mit Debuggen und Suchen verbringen.  :-|

Oder anders formuliert: Wenn mich am EeePC der Lüfter nervt, kann ich dann einfach einen Kälte-Akku aus dem Eisfach drunterlegen?

Mit dem DTA-Leser stelle ich nun ein Beispielskript online um Dateien entgegenzunehmen und ihren Inhalt anzuzeigen. Ist in einigen Situationen recht nützlich…

pfSense: M0n0wall’s big brother; bigger, more complete, and more customizable. But with one major problem: no IPv6 support. It is 2010, with only 1-2 years until the IPv4 address pool exhaustion… deploying network infrastructure without IPv6 support is ridiculous and not an option. – Another problem seems to be a limited support for bridge setups: There are always a number of standard pf rules, which are hard to circumvent in case of problems. I nearly settled to use the web-interface for IPv4, and insert my own IPv6 rules into the PHP scripts. But this would have made it even harder to maintain than a solution without any web-interface.

NanoBSD: So I finally took the chance to build my own small FreeBSD system for the task. NanoBSD is basically a script to do a FreeBSD ‘make world’, allow for some customization, and finally put everything into a CF-ready disk image. Of course the first attempt required several changes after installation (it’s really hard to think of all configuration steps beforehand), but everything went well without major problems.

Thus I chose NanoBSD. YMMV, and I would not recommend it for anyone not familiar with BSD. – But with four other BSD servers the additional maintenance effort is really small; possibly even easier than with any non-standard or web-based configuration.

I like the new logo for Mailman.

To extract single DB dumps from a complete dump find the line numbers where the single DB dumps start. Then use sed to print only the lines from the start of the searched DB and the next one. mysqldump seems to use separate passes for data, stored routines, and triggers — so there may be multiple ranges of lines in a complete dump:

fgrep -n 'Current Database: ' dump_all.sql
sed -n -e '86226,93282p' -e '123249,123254p' \
  dump_all.sql > db_test.sql

diff loads the files it works on into memory, thus it cannot be used for large files (>= 1Gb). To extract multiple DBs or to compare dumps it is useful to split the SQL dump at DB boundaries:

split -p 'Current Database: ' dump_all.sql

The resulting partial files can be renamed/concatenated to one file per DB (using tcsh syntax here):

foreach f ( x?? )
  set dbname=`head -1 $f \
  | sed -e 's/^-- Current Database: .\(.*\).$/\1/' \
    -e 's/^-- MySQL dump.*$/dumpheader/'`
  test $dbname && cat $f >> part-${dbname} && rm $f
end

If we did this with two SQL dumps in $dir1 and $dir2, then we can compare them chunk by chunk (assuming every DB on itself is small enough to fit into memory for diff):

foreach f ($dir1/part-*)
  diff --ignore-case --ignore-space-change \
    --ignore-blank-lines -u \
    $dir1/$f $dir2/$f >> /tmp/diff.out
end

Non-techies see these resources as abundant and dirt-cheap because they do not cost any money. – Whereas techies regard them are scarce and expensive because no amount of money can completely revert a bad allocation.

I highly recommend to participate because it is a great opportunity to get the experience of working with a mentor in a large open source project.

And don’t be afraid to apply (beware of impostor syndrome). If you have a project in mind and are able to describe in a few sentences why it’s useful then you should go for it. If you have doubts or questions then you can still ask on the project’s mailinglist or IRC channel to get a second opinion.
