Chaosradio Express: Der Hacker-Podcast der anderen Art
Ausgehend von der Aktion “CRE Kettenblogging für den Weltfrieden” alias blog4CRE ist dieser Post entstanden als Follow-up von Post 91 und der Follow-up von mir Post 93:
Auch auf die Gefahr hin, dass ich hier Kommentare erhalte, was “Kaffee” und “Wahlrecht und Wahlsysteme” denn mit Hacker zu tun haben.
Chaosradio Express kurz CRE geht den Dingen auf den Grund, sei es in technischen Dingen, Geschichte und Entstehnung wie auch im Bereich Kultur und Gesellschaft.
Dabei behandelt Tim Pritlove mit seinen kompetenten Gästen im Besonderen kritische Themen:
Stellt Fragen, welche die Medienwelt und die Gesellschaft schon lange nicht mehr stellen, und hinterfragt Antworten, welche die Gesellschaft schon längst akzeptiert hat.
Kampf gegen die Zensur oder die Untergrabung der Demokratie mittels Wahlcomputer und das dazugehörige Hands-on Erfahrungen mit Wahlcomputern ist nur ein Beispiel.
Auch die technischen Podcasts wie GSM Hacking, Wireles Mesh Networking und das Update dazu sind äusserst hörenswert. Ich vergeblich versucht, eine persönliche Favoritenliste aufzustellen: Es gibt einfache zu viele einzigartige Sendungen, welche ich gerne gehört und auch immer wieder gerne höre. Viele Sendungen sind Zeitlos und schon fast ein Stück Netzkultur geworden. Hört einfach mal rein!

JSendNSCA: Nagios Passive Checks in Java
JSend NSCA [1] is a Java API and command line tool for sending Nagios [2] Passive Checks to the Nagios NSCA add on.
By using the JSend NSCA core API, you can easily integrate your Java applications into a Nagios monitored environment thereby notifying Nagios of problems and issues during the running of your application.
The Jsend NSCA CLI command line tool wraps the API and allows you to send passive checks from the command line.
Please consider: Nagios has been forked, so it is also known as Icinga.

OpenNMS: enterprise-grade network monitoring platform
OpenNMS [1] is an enterprise-grade network monitoring platform developed under the open source software model. It consists of a community-supported, open-source project as well as an organization offering commercial services, training and support.
The full featured monitoring solution is written in Java and is released under GNU Public License. I used to use Nagios, but OpenNMS seems to be a Nagios killer. At least it is worth taking a deep breath. Get an impression on your own and try out the demo (username:demo password:demo).
In the current stable release technology preview series 1.7.0, OpenNMS uses the Spring Framework (WP: Spring Framework) 2.5 and a RESTful Interface was added.

GPGMail: GnuPG on Mac OS Mail
Via Mike:
I usually use Mozilla’s Thinderbird and the GnuPG Plugin Enigmail.
Mail on Mac OS is quite good but never had a GnuPG integration. If you need to use Mail and GnuPG, there is GPGMail, but keep in mind:
GPGMail is a complete hack, relying on Mail’s private internal API. Use it at your own risks!
Mac OS X 10.5 is required and it is released under BSD license (recently changed).
