FreeBSD for High Density Servers

To promote FreeBSD to High Performance Computing or High Density Servers under such circumstances, it is considered to be very important to share the information about how to install, how to setup, how to manage, how to patch and how to fix to work FreeBSD correctly with those machines. In this session, I am going to talk about how to install FreeBSD to MicroModularServer and how to manage and control those servers. To install FreeBSD to High Density Servers including NEC MicroModularServer or HP Moonshot, you need another skill compared to install to common PCs and rack mount servers. This kind of servers (low energy consumption, low computing power and high space efficient) are good for too many edge servers/web servers at limited rack space, for example, as an alternative system for Blade servers or many cores servers like Sun Fire T1000/T2000.

Billion Tables Project (BTP)

Aka how long a "\dt" takes on a 1B tables database Usually "large" databases are considered as such for the high number of records they hold, reaching billions or even more than that. But what about creating a billion... tables? Sometime ago, this apparently crazy question was found in a database soup. It may not be your day-to-day task, but the task of creating them exposes some topics about PostgreSQL internals, performance and large databases that may be really worth for your day-to-day. Join us for this talk, where we'll be discussing topics such as catalogue structure and storage requirements, table speed creation, differences between PostgreSQL versions and durability vs. table creation speed tradeoffs, among others. And, of course, how long a "\dt" takes on a 1B tables database :) This talk will explore all the steps taken to achieve such a result, raising questions on topics such as: The catalogue structure and its storage requirements. Table creation speed. Durability tradeoffs to achieve the desired goal. Strategy to be able to create the 1B tables. Scripts / programs used. How the database behaves under such a high table count. Differences in table creation speed and other shortcuts between different PostgreSQL versions. How the storage media and database memory affects the table creation speed and the feasibility of the task. If it makes sense to have such a database. It is intended to be a funny, open talk, for a beginner to medium level audience, interested in large databases, performance and PostgreSQL internals.

auditdistd - Secure and reliable distribution of audit trail files

Security Event Audit is a facility to provide fine-grained, configurable logging of security-relevant events. Audit events are stored in trail files that can be used for postmortem analysis in case of system compromise. Once the system is compromised, an attacker has access to audit trail files and can modify or delete them. The auditdistd daemon's role is to distribute audit trail files to a remote system in a secure and reliable way. The talk will provide background to the Security Event Audit facility in FreeBSD and will describe auditdistd daemon in detail. The auditdistd daemon is a good example of using modern sandboxing mechanisms, like capsicum. During the talk audit subsystem and auditdistd daemon will be presented live.

BSD Multiplicity

Ever since the University of California, Berkeley CSRG implemented the chroot(8) command and system call in its BSD operating system in 1982, the community-developed BSD Unix derivatives have set the standard for the introduction of plurality to the conventionally-singular Unix computing model. Today's system operators and developers have an array of BSD-licensed multiplicity strategies at their disposal that offer various degrees of both isolation and virtualization when introducing plurality. This paper will survey current and experimental BSD multiplicity strategies including chroot, FreeBSD jail, NetBSD/Xen, Amazon EC2, compatlinux, GXemul and SIMH, plus experimental strategies such as FreeBSD BHyVe, compatmach, Usermode NetBSD, Dragonfly BSD vkernel, OpenBSD sysjail and NetBSD mult. As an applied survey, this paper will both categorize each multiplicity strategy by the Unix environment to which it introduces plurality and demonstrate the usage of the utilities relating to each solution. The survey criteria consist of five distinct Unix environments to which plurality is introduced: • Machine Multiplicity, as distinguished by the introduction of native and foreign hardware system and their distinct Instruction Set Architectures defined by distinct physical hardware systems, virtualized instances of them, or software emulattions of them (NetBSD-Xen/EC2, GXemul, SIMH and BHyVe) • Kernel Multiplicity, as distinguished by a plurality of executing kernels (Usermode NetBSD, Dragonfly BSD vkernel) • Init Multiplicity, as distinguished by distinct kernel-spawned init processes and their descendant processes (mult) • Userland Multiplicity, as distinguished by distinct userlands with optional process tables and their descendant processes (chroot, FreeBSD jail and sysjail) • API Multiplicity, as distinguished by distinct foreign Application Programming Interface compatibility layers (compatlinux, compatmach) The reader will thus come away with a set of working examples for each solution that they can implement on their own. In addition, this survey addresses key host and guest administrative considerations applicable to each multiplicity solution: • Storage Device considerations: Are they hardware or software-based? What image and file system formats are supported? • Network Device considerations: Are they configured by the host? From within the guest? • Console Device considerations: Does the guest appear on the host console? Is it redirected to a network-aware solution such as VNC or X11 over SSH? • Kernel considerations: Is the native or foreign guest kernel modified? Does it reside within or outside the guest userland? • Userland considerations: Is the guest userland modified? Does it lend itself to customization through additive or subtractive techniques?

pfSense 2.1: IPv6 and more

pfSense is a BSD licensed customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution. This session is being presented by the founders of the pfSense project, Chris Buechler and Scott Ullrich. At the time of BSDCan 2012, pfSense 2.1 will be newly released. This release adds IPv6 support to nearly every portion of the system, as well as some other smaller changes. This session will cover all of the changes in the 2.1 release, primarily focusing on adding IPv6 support to your existing deployments. With IPv4 address space dwindling and World IPv6 Launch coming up in June, now is the time to bring up IPv6 on your networks. While IPv6 brings new benefits, it also poses new security and connectivity considerations, which will be covered. Attendees will come away with all the latest on the project, as well as knowledge to securely bring their networks onto the 21st century Internet with IPv6.

XPlanung für einen Flächennutzungsplan mit PostGIS und QGIS

Im Flächennutzungsplan (FNP) wird die beabsichtigte Bodennutzung des Gebietes einer Gemeinde dargestellt (5 BauGB). In der Stadt Jena wurde im Jahre 2015 mit der Neuerstellung des FNP begonnen. Die Stadt hat seit mehreren Jahren das freie Desktop-GIS QGIS im Einsatz, als Datenspeicher dient eine PostgreSQL/PostGIS-Datenbank. Am Anfang stand deshalb die Überlegung, wie die Daten für einen FNP in einem GIS im allgemeinen und in PostGIS im besonderen sinnvoll modelliert werden können. Im Projekt XPlanung wird seit mehreren Jahren das Datenaustauschformat XPlanGML entwickelt, das den verlustfreien Austausch von raumbezogenen Planwerken ermöglichen soll. XPlanung wird schon seit 2008 vom Deutschen Städtetag und vom Deutschen Städte- und Gemeindebund zur Einführung empfohlen. Da es bisher jedoch keine frei verfügbare Umsetzung des XPlanungs-Standards für PostGIS gibt, wurde zunächst der Standard (Version 4.1) in der Datenbank implementiert. Jede Objektart wird dabei durch eine eigene Tabelle repräsentiert; Trigger sorgen für die Datenkonsistenz zwischen Eltern- und Kindklassen. Die Visualisierung und Bearbeitung der Daten erfolgt von QGIS aus mit einem eigenen Plugin und dem Plugin DataDrivenInputMask. Für jede FNP-Objektart gibt es eine Standarddarstellung in Anlehnung an die PlanZVo. Vorteile der dargestellten Lösung: für jeden Sonderfall gab es bisher eine sinnvolle Anwendung innerhalb des Standards; da XPlanung bereits alle im Zusammenhang mit einem FNP denkbaren Attribute enthält, war es folglich noch nicht nötig, weitere Attribute hinzuzufügen. Die Sachdaten lassen sich in QGIS gut editieren und eine PlanZVo-konforme Darstellung ist mit den Darstellungsoptionen von QGIS möglich. Als Nachteil erwies sich insbesondere die Tatsache, dass die Datenerfassung eine Aufgabe ist, die entsprechend qualifiziertes Personal und ein gewisses Verständnis des komplexen Standards voraussetzt. Noch gar nicht realisiert sind z.Zt. Schnittstellen, also die Übernahme von Plänen im XPlanGML-Format bzw. die Ausgabe eigener Pläne als XPlanGML.

Is there life in Virtual Globes?

Virtual globes have been widely used during last decade mainly for simulating observations of the earth from the outer space and navigation experiences over its surface which may be portrayed with various types of views and textures. The present work aims to extend virtual globe capabilities by incorporating three dimensional events on them. Such events may include animation and motion effects on 3D models representing real world living or inanimate spatial objects, modeling of natural resources and phenomena representations and any type of geovisualized activities and demonstrations.

Druckbare Karten im Web erzeugen

Es gibt mittlerweile eine Vielzahl von Online-Diensten die OSM-Daten im Web präsentieren, aber nur die wenigsten davon sind auch geeignet druckbare Dokumente zu erzeugen. Dieser Vortrag wird vor allem eine Weiterentwicklung von MapOSMatic vorstellen; eine Service der sowohl großformatige als auch mehrseitige hochauflösende Kartendokumente erzeugt. MapOSMatic erzeugt großformatige Karten als PDF, SVG oder als hochauflösendes PNG. OSM-Daten werden mit Hilfe anpassbarer Stylesheets erzeugt und optional mit zusätzlichen textuellen und grafischen Informationen ergänzt, wie z.B. Straßenlisten für den sichtbaren Bereich. Die Ausgabe kann dabei als einzelne große Karte oder als atlasartiger Mehrseiter erfolgen. Das ursprüngliche MapOSMatic ist bereits länger verfügbar, die Entwicklung und Pflege ist aber leider in den letzten Jahren weitestgehend zum Stillstand gekommen. Der Vortrag wird sowohl das ursprüngliche Projekt als auch meine eigenen Anpassungen und Erweiterungen vorstellen.

DevOps Transformation at Absa Bank: Technical Evolution; Cultural Revolution

There is one thing that makes up DevOps. Tools. Tools and process. Okay two things. Tools, process and culture. Among the things that make up DevOps, tools, process and culture are three. And of course, nobody expects the Spanish Inquisition, which makes it tough to get teams to buy into new ways of doing things. We are delighted to share our DevOps transformation journey with you. First, there's the technical journey, such as how we are automating our infrastructure, and our software engineering practices (see www.practicesofmastery.com). Then there's the process journey such as how we have redefined our SDLC to remove friction, and our use of scrum. Finally, there's the cultural journey, such as how we're forming teams around customer value rather than functional silos, as well as our guerilla marketing campaigns (see www.productivitypact.org). Software mediates every interaction with our customers and the purpose of our transformation is to increase our ability to deliver higher quality software at higher velocity in the pursuit of customer value.

Test-Driven Development by Example

Are you writing software that can survive a rigorous refactor? Would a well written suite of tests make you feel more confident as you iterate? How do you get feedback as you add new features or fix a bug? Join me for an intense 25 minute live coding session where I build an ember application from the ground up test-first with nothing but the terminal and my favorite text editor! I'll share some of the tribal knowledge about what makes a great unit or functional test and how you decide to write one over the other.

Interactions Design with Ember 2.0 and Polymer

You've heard the hype about web components, but what does the spec provide other than small, re-usable chunks of markup? Web components provide an incredibly powerful and declarative way of structuring web apps. The Polymer platform in particular holds many hidden secrets, including a paradigm shift for interaction design: an animation library that bridges the gap between application states, providing a sense of context and clarity of purpose as you move through an app experience. We will show you how to leverage the power of Ember 2.0 and Polymer to create remarkable user experiences.
