- excercising the tools within the Vagrant VM is fun …
- and certainly supplying the VM is a good and rather low-trouble start for the studies …
- but installing the tools in your real-life environment is the “challenge” …
- Appendix A lists the tools and their home pages
- http://csvkit.readthedocs.org – I just installed the csvkit, because I had a serious application for it – the Python pip utility showed a message grunting about a missing
Python.h, but csvlook etc got installed properly nevertheless

systemd journalctl is buggy, isn’t it?! config: x86_64-opensuse-13.2
- http://www.b.shuttle.de/hayek/mediawiki/w/index.php?title=Main_Page#systemd_and_the_journal
- my configuration:
x86_64-opensuse-13.2
# this is the code suggested by Lennart Poettering, # but it does not work for me # (complains improperly about $XDG_RUNTIME_DIR) : $ journalctl --since=yesterday -p err # but this works: $ journalctl -b -p err # and this, too: $ journalctl --since=yesterday

Bronshtein, Semendyayev, Musiol, Mühlig: Handbook of Mathematics, 6th Edition
- https://en.wikipedia.org/wiki/Special:BookSources/978-3662462201
- https://de.wikipedia.org/wiki/Spezial:ISBN-Suche/978-3662462201
- http://www.amazon.de/dp/3662462206
- https://de.wikipedia.org/wiki/Taschenbuch_der_Mathematik – nowadays (resp. for quite some while) there have been 2 parallel editions (plus translations) of this classic math book
As of 2015-04-02 you can’t even purchase the 6th edition as paperback – but there are sources, where you get it as PDF. Isn’t that appalling?

Yael Naim’s 2015 album “Older” on YouTube
With the help of ProxFlow I can watch it / listen to it w/o problems. Well, still pictures only, and I got the album as CD anyway – but on YouTube you can comment and ask questions …

my Synology DS713+ now runs a “hibiscus-server”, and my wrapper layer (bash+perl) and also sendxmpp
- https://www.synology.com/en-global/products/DS713+
- https://www.synology.com/en-global/products/DS715+ – not yet out
- https://www.synology.com/en-global/products/DS215j
- of course I would have preferred a DS715+ or DS714+, but they are not available, the DS713+ isn’t really as low power as the DS215j
- it’s fun to see my bash and Perl scripts to run just the same on an openSUSE machine and on a Synology DiskStation – with the help of ipkg (and a few tweaks)
- notification: running sendxmpp with literate “IM” (= instant messaging) is just amazing!!!
- how to explain, that running this software on such a capable “tiny box” looks so much better than on general purpose server hardware?
- if I only had a serious idea of how to create a business (that feeds me a little) from this!!!

more procmail rules to separate bulk from serious business e-mail messages
Bulk and serious messages are both from the same businesses, aren’t they? Yes, that’s right, but they use different From/Return-Path/… header field values.
So how to recognise bulk messages?
- Sometimes they use “news.” within the “Return-Path“.
- Sometimes they use the “List-Id” header field.
- Sometimes they use the “List-Unsubscribe” header field.
And they like changing they bulk mailing software resp. their providers, that certainly makes it tedious. But … it’s also fun to catch them, and to receive fewer messages within the message folders for the serious stuff, and to see them going to the message folders for the bulk stuff.
Right, and I am still (sort of successfully) improving the pretty printer for the procmail log file … – lots of relevant fields get UTF-8 / ISO-8859-1 / ISO-8859-15 encoded these days, and I certainly want to only see their decoded equivalents – and procmail itself only shows you the encoded originals.
