DNS is easy. You type bsdcan.org in your browser's address bar, hit enter and you will be greeted by your favorite BSD conference's start page. Actually... We will start by giving a short introduction into DNS from the perspective of a client. We will explore: where to send questions to: upstream resolvers learned from dhcp / router advertisements / static quad-x resolvers vs. doing recursion ourselves, what questions to ask: qname-minimization (yes or no), what...

Unveil in OpenBSD Last year the unveil() system call was introduced in OpenBSD 6.4 Unveil has continued to evolve and be included in more programs in OpenBSD base, as well as some in the OpenBSD ports tree. Unveil has gained new features and semantics as a result, with some of the underlying implementation details in the kernel changing considerably. This talk discusses unveil, how it is used in programs, as well as new changes to...

Automatically testing the pf firewall, using network stack virtualisation. For fun and profit, or at least for the sake of fewer bugs. We're all convinced that automated tests are a good idea. For some applications (e.g. grep, awk, cc, ...) this is very straightforward. Others are a lot harder to test, for example firewalls. Typically testing firewalls takes two to three hosts. One to send traffic, the firewall test host and one to receive traffic....

Many of us spend days and weeks planning, and implementing strategies for disaster recovery in the server room, whether corporate or personal. How many of us, however, can really say we're prepared to recover our primary computing system in the office ... or on the go? Or that it's secure enough that if it were lost, stolen, or seized we wouldn't lose important data, or lose sleep? In this talk we'll look at the various...

Netflix has built a CDN to distribute streaming media through most of the world. The content caches run a lightly customized version of the FreeBSD operating system's head branch. This presentation will describe Netflix's development process, and give some reflections on Netflix's experience using FreeBSD head in production. Netflix has built a CDN, called Open Connect, to distribute streaming media through most of the world. According to Sandvine, Netflix accounts for approximately 15% of all...

FOSDEM (Free and Open Source Development European Meeting) is a European event centered around Free and Open Source software development. It is aimed at developers and all interested in the Free and Open Source news in the world. Its goals are to enable developers to meet and to promote the awareness and use of free and open source software.

This talk will focus on 10 important features that makes it easier for users and developers alike to work with Exherbo. While the talk will focus on the current state of Exherbo and the short-term future the ideas being presented should be equally interesting for other distribution developers and users.

Wood is a renewable resource that can be used for a large number of applications ranging from material to chemical to energy applications. In the past, wood resources have been underused in Switzerland, but this is changing rapidly with the demand for more environmentally sustainable products and energy. It is therefore crucial to use the available wood resources in an ecologically optimal way. With this last forum in 2015, we intend to provide to the...

Laboya liegt an der Südküste Westsumbas (Ostindonesien), einer Insel, die aufgrund ihrer Lage nie von der Hindu-Kultur beeinflusst worden war. Erst zu Beginn des 20. Jhs. wurden Christentum und Islam auf Sumba eingeführt. Noch heute glauben die Einwohner an den Einfluß der Ahnen. Die Lebenden müssen sie nähren und für sie beten, um ihren Segen zu erhalten. Padu und Nyale bilden die beiden Hauptzeremonien im Jahreskreis dieser Ackerbaukultur (Reis, Mais und Maniok). Padu bedeutet "Bitterkeit",...
