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.

Cesium - der 3D-Globus im Web

Cesium ist ein performantes und interoperables Tool für die Visualisierung von Daten im dreidimensionalen Kontext. Stichworte zum Vortrag: 3D - JavaScript - Open Source - WebGL - Zeitabhängige Darstellung - OGC Standards - Openlayers 3 API - Demos und Beispiele. Mit der JavaScript Programmbibliothek Cesium kann ein 3D-Globus für das Web erstellt werden, ohne dass für die Visualisierung Plugins gebraucht werden. Cesium benutzt WebGL und unterstützt ausserdem OGC-Standards wie WMS oder WMTS. Dies macht es zu einem performanten und interoperablen Tool für die Visualisierung von Daten im dreidimensionalen Kontext. Die Präsentation stellt das Cesium.js Projekt vor und möchte folgende Fragen beantworten: - Ein Opensource 3D Globus - was kann Cesium? - Performante mehrdimensionale Visualisierung im Web - was steckt dahinter? - 3D ist überall - wo wird Cesium eingesetzt? Ausserdem wird die Kombination von Openlayers3 mit Cesium vorgestellt und ein Ausblick über die nächsten Entwicklungen gegeben.

FreeBSD Unified Deployment and Configuration Management

When we needed dozens of storage, processing and front-end machines for a prototype of a new cloud media service, we developed a cost-effective, but technically challenging hybrid strategy of purchased, rented dedicated and rented virtual servers. FreeBSD was an easy choice thanks to its performance, reliability, and unparalleled ease of management on a per–node level. However, while the number of infrastructure–level tasks kept growing and we needed to scale through beta and release stages, there was an obvious need to reduce complexity. After a year of tentative design and experimenting with partial solutions, we started implementing in November 2011, the result-in-progress being something we call unified configuration management (and deployment), bringing immediate returns on time invested. The talk focuses on a new unified approach to deploying and managing modern versions of FreeBSD across a wide variety of technical and administrative circumstances: different countries, data centers, hardware, access policies, boot methods, networking, support contracts, machine roles, etc. While avoiding any popular Linux-centric CM systems, such as Puppet, Chef, and CFEngine, we achieve very low complexity by leveraging rc(8), loader(8), glabel(8) and other existing instruments, such as pkgng, to their potential as necessary. The cornerstone is keeping configuration and deployment versioned and unified — same across all cases, with no duplication of common parts and very simple specification of per-role/per-case peculiarities. The approach spans everything from installation and booting to managing third-party and custom site-specific software. The method is being actively developed and applied in production environment of a popular online music service.

An Overview of Locking in the FreeBSD Kernel

The FreeBSD kernel uses seven different types of locks to ensure proper access to the resources that it manages. This talk describes the hierarchy of these locks from the low-level and simple to the high-level and full-featured. The functionality of each type of lock is described along with the problem domain for which it is intended. The talk concludes by describing the witness system within the FreeBSD kernel that tracks the usage of all the locks in the system and reports any possible deadlocks that might occur because of improper acquisition ordering of locks.

An Introduction to Verifiedexec in NetBSD

The verifiedexec feature has been part of NetBSD for some years now. It seems that a lot of people are unaware of the feature or do not know the full capabilities of verifiedexec. This talk will introduce the feature, what it can do and also what it could be capable of with some kernel changes. The verified execuction feature is a unique extension to the NetBSD kernel that allows an administrator to ensure the binaries and files that are being accessed have not been modified by comparing the fingerprint of the on-disk file with a "known good" copy of the fingerprint kept in kernel memory. This allows very fine grain control over what will be executed on the machine, even by root, and can provide assurance that files have not been modified. In this talk I will go over some of the history of verified execution, how it works and what it can do, then finally move on to what the next steps I want to take in the development of veriexec. Verified execution has been in NetBSD for a long time but it seems to be a feature that that is not widely known about, hopefully this talk can raise its profile somewhat.

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?

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.

A RESTful API for linking geodata

Publishing open data is a trend movement but still nowadays geographical information are often released as shapefiles despite this common format isn't recommended for such scope. We have used GeoNode, a spatial data infrastructure for publishing open geodata through standard OGC Web Services, with a RESTful API to model such resources to the semantic interoperability. GeoLinkeData is a django application based on a GeoNode template that allows to publish interlinked shapefiles as triple stores and search them with GeoSPARQL queries from a Virtuoso backend.

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.

Ephemeral Apps With Chef, Terraform, Nomad, and Habitat

In addition to composition and portability, one of the more commonly overlooked advantages of moving to microservices, containers, and infrastructure-as-a-Service is the ability to create highly-ephemeral, one-off environments for almost any purpose. Imagine a world where a code change can be tested in a completely isolated environment where 100% of the resources are ephemeral. Say goodbye to long-lived staging or QA environments and say hello to Chef, Terraform, Nomad, and Habitat. Terraform and Chef provide the foundation to build and provision infrastructure resources for your application. Running in parallel, these tools can often provision all the infrastructure required for a cluster in 2-3 minutes. Part of that process installs Nomad, an application scheduler akin to Mesos or Kubernetes, and the supporting resources for Habitat, which enables you to automate any app on any platform. Joined together, this toolset enables rapid development, testing, QA, staging, and more. This demo-driven talk with go from nothing to fully-empheral in snap of, press of a button.
