The Monkeys Chased Away Puffy, or, Replacing OpenBSD with NetBSD at the Point of Sale

Geschrieben von Marc Balmer am Mon, 12/21/2009 - 12:13

About one year ago, I wrote about how we used OpenBSD at the point of sale at the Basel Zoo. Well, the good news first: We replaced OpenBSD by NetBSD for our POS applications, both in development, but also for deployment. That might sound like a radical step, but in fact it is not. It is just the consequence from OpenBSD not being ready for prime-time in an enterprise world. The lack of proper SMP support, for one, is a major problem with todays computers being mostly multi-core.

NetBSD's GPIO Revisited

Geschrieben von Marc Balmer am Sat, 07/25/2009 - 21:11

I reworked the GPIO framework in OpenBSD last fall. Now I have taken my work to NetBSD and updated their GPIO implementation. While there, I corrected some mistakes made in the OpenBSD implementation and took it a step further. More development will take place in NetBSD, and there is quite a few interesting upcoming things to watch out for...

If you are interested in the latest userland accessible GPIO stuff, and the most up-to-date GPIO implementation, then keep an eye on NetBSD -current. This is where I am working on new stuff.

See http://blog.netbsd.org/tnf/entry/gpio_revisited for details. And stay tuned.

Starting X11 Applications on OpenBSD at Boot Time

Every now and then someone asks on the OpenBSD public mailing list if it is possible to have a graphical application start at system boot time, circumventing the usual xdm login screen. I had to do exactly this a web browser is to be started for visitors to browse the web. Another application are point of sale systems where the POS application handles the login.

When Puffy Meets the Monkeys, or, OpenBSD at the Point of Sale

Basel has one of Europe's most beautiful zoological gardens, called the Zolli by the locals. It has a breathtaking aquarium with an enormous variety of rare fish, corals and lower animals. Pufferfish and Xenocara can be watched in their natural habitat. Starting january 1st, 2009, those two fish no longer only swim around in their aquariums but every visitor to the zoo must pass them...
